Telomeres are nucleotide sequences located at the ends of chromosomes that promote genome stability. Changes in telomere length (dynamics) are related to fitness or life expectancy, and telomere dynamics during the development phase are likely to be affected by growth and stress factors. Here, we examined telomere dynamics of black-tailed gull chicks (Larus crassirostris) in nests with and without siblings. We found that the initial telomere lengths of singletons at hatching were longer than those of siblings, indicating that singletons are higher-quality chicks than siblings in terms of telomere length. Other factors likely affecting individual quality (i.e., sex, laying date, laying order of eggs, and clutch size) were not related to telomere lengths. Within broods, initial telomere lengths were longer in older chicks than in younger chicks, suggesting that maternal effects, which vary with laying sequence, influence the initial lengths. Additionally, telomeres of chicks with a sibling showed more attrition between hatching and fledging than those of singleton chicks, suggesting that being raised with siblings can cause a sustained competitive environment that leads to telomere loss. High growth rates were associated with a low degree of telomere shortening observed in older siblings, perhaps because slower growth reflects higher food stress and/or higher aerobic metabolism from increased begging effort. Our results show that developmental telomere attrition was an inevitable consequence in two-chick nests in the pre- and post-hatching microenvironments due to the combination of social stress within the nest and maternal effects. The results of our study shed light on telomere dynamics in early life, which may represent an important physiological undercurrent of life-history traits. PMID:27902754

Ample studies have established that parents as well as peers function as role models in the development of adolescents' alcohol use. The role of siblings, however, has been largely neglected despite the long-term nature of a sibling relationship. The present study examined the impact of siblings on drinking behavior of adolescents using longitudinal data from 416 sibling dyads. Moreover, we explored which factors (gender constellation of the sibling dyad, quality of the sibling relationship, and similarity in norms about alcohol) affect reciprocal influences in alcohol use of siblings. Descriptive analyses showed that although older siblings drink more frequently and intensively than the younger siblings, moderate associations were found between frequency and intensity of drinking in siblings. Findings of structural equation modeling demonstrated that alcohol use of the older sibling marginally affected drinking of the younger sibling one year later. Drinking of the younger sibling did not affect drinking of the older sibling. Further, we found no moderating effects of having the same or opposite gender as a sibling, a low or high quality relationship, and the same or different norms about alcohol, on the association between siblings' alcohol use and adolescents' drinking over time.

Sibling relationship quality moderates the associations between parental interventions and siblings' independent conflict strategies and outcomes.

This study extends research on sibling conflict strategies and outcomes by examining unique and interactive associations with age, relative birth order, sibling relationship quality, and caregivers' interventions into conflict. Each of 62 sibling dyads (older sibling mean age = 8.39 years; younger sibling mean age = 6.06 years) discussed 1 recurring conflict alone (dyadic negotiation) and a 2nd conflict with their primary parental caregiver (triadic negotiation). Negotiations were coded for children's conflict strategies, outcomes, and caregiver interventions; each family member provided ratings of sibling relationship quality. Results revealed that age was associated with siblings' constructive strategies, particularly in the dyadic negotiation. With age controlled, younger siblings referred more frequently to their own perspective. Caregivers' future orientation in the triadic negotiation was associated with children's future orientation in the dyadic negotiation; however, this association was most evident when sibling relationship quality was high. Similarly, caregivers' past orientation was positively associated with dyadic compromise, especially when relationship quality was high. Results reveal the value of simultaneously considering associations among parental, affective, and developmental correlates of sibling conflict strategies.

Tensions among siblings in parent care.

Lashewicz, Bonnie; Keating, Norah

2009-06-01

From a place of "genealogical equivalence" as children of their parents, siblings spend a lifetime developing separate identities. As parents near the end of their lives, issues of sibling equivalence are renegotiated in the face of equal obligations to provide care and equal entitlement to parent assets. In this paper, we hypothesize how unresolved issues of rivalry for parent affection/attention among siblings may be reasserted when parents need care. Data are drawn from a project about how parent care and assets are shared. In-depth interviews with three sibling groups experiencing conflict over sharing parent care and assets along with six Canadian legal case portrayals of disputes among siblings over how parent care and assets were shared are examined. Findings are that disputes occur when siblings perceive others as dominating parent care and assets through tactics such as separating the parent from other siblings and preventing other siblings from being engaged in decisions about care and assets. Discussion is focused on paradoxes faced by siblings given expectations for equity in parent relationships alongside perceived pre-eminence in care and asset decisions.

We examined profiles of sibling relationship qualities in 246 Mexican-origin families living in the United States using latent profile analyses. Three profiles were identified: Positive , Negative and Affect-Intense . Links between profiles and youths' familism values and adjustment were assessed using longitudinal data. Siblings in the Positive profile reported the highest familism values, followed by siblings in the Affect-Intense profile and, finally, siblings in the Negative profile. Older siblings in the Positive and Affect-Intense profiles reported fewer depressive symptoms than siblings in the Negative profile. Further, in the Positive and Negative profiles, older siblings reported less involvement in risky behaviors than younger siblings. In the Negative profile, younger siblings reported greater sexual risk behaviors in late adolescence than older siblings; siblings in opposite-sex dyads, as compared to same-sex dyads, engaged in riskier sexual behaviors. Our findings highlight sibling relationship quality as promotive and risky, depending on sibling characteristics and adjustment outcomes.

The role of older siblings in infant motor development.

PubMed

Leonard, Hayley C; Hill, Elisabeth L

2016-12-01

Previous research has suggested that infant motor skills may be affected by older siblings but has not considered whether this is due to specific characteristics of the older sibling or of the quality of the sibling relationship. The current study used a longitudinal diary method to record infant motor milestones from 23 infants with older siblings along with parent reports and standardized assessments of motor skills. Parent reports of the older siblings' motor skills and the sibling relationship were also collected until the infants were 18months old. The motor skills, age, and sex of the older siblings were not significantly related to any measure of infant motor development. A significant correlation was revealed between perceived agonism between siblings and infant fine motor skills at 18months, suggesting the importance of considering reciprocal effects of motor development on sibling relationships. Overall, the suggestion that older siblings may provide a good model of motor skills for infants is not supported by the current data. In the future, it will be important to assess the dynamic interactions between different factors in predicting infant motor development, allowing early identification of motor difficulties, which could affect other areas of cognitive development and health.

The Role of the Broader Autism Phenotype and Environmental Stressors in the Adjustment of Siblings of Children with Autism Spectrum Disorders in Taiwan and the United Kingdom.

Tsai, Hsiao-Wei Joy; Cebula, Katie; Fletcher-Watson, Sue

2017-08-01

The influence of the broader autism phenotype (BAP) on the adjustment of siblings of children with autism has previously been researched mainly in Western cultures. The present research evaluated a diathesis-stress model of sibling adjustment using a questionnaire study including 80 and 75 mother-typically developing sibling dyads in Taiwan and the United Kingdom (UK). UK siblings reported elevated adjustment difficulties compared to the Taiwanese sample and to normative data. Whilst higher BAP levels were generally associated with greater adjustment difficulties, differences were found across cultures and respondents. Although significant diathesis-stress interactions were found, these were in the opposite direction from those predicted by the model, and differed across cultural settings. Implications for culturally-sensitive sibling support are considered.

Bidirectional associations between sibling relationships and children's problem behaviors are robust, and links with prosocial behavior have also been reported. Using cross-lagged models, we were able to conservatively test temporal directions of links between positive and negative aspects of sibling relationships and children's prosocial behavior and conduct problems across a 3-year time span in middle childhood. The Avon Longitudinal Study of Parents and Children (ALSPAC; http://www.bristol.ac.uk/alspac/researchers/data-access/data-dictionary/) is an ongoing population-based study designed to investigate the effects of a wide range of factors on children's health and development. For the purposes of the current analyses, we included 2,043 ALSPAC families who had just 1 older sibling as well as the target child, with an age gap of no more than 5 years. Mothers reported about the quality of the sibling relationship and both children's prosocial behavior and conduct problems when the target child was 4 years of age and again when the target child was 7 years old. Confirming our hypothesis, individual child behavior was predictive of sibling relationship quality, and sibling relationship quality was predictive of later child behavior, providing robust evidence of bidirectionality for both prosocial behavior and conduct problems. It would be consistent to expect that an improvement in either sibling relationship quality or individual children's behavior could have a positive spill over effect. We also found evidence of older sibling dominance in the domain of prosocial behavior and the positive aspects of sibling interaction. (PsycINFO Database Record (c) 2017 APA, all rights reserved).

Depression is a clinically relevant dimension, associated with both positive and negative symptoms, in patients with schizophrenia. However, in siblings it is unknown whether depression is associated with subclinical positive and negative symptoms. Method Depressive symptoms and their association with positive and negative symptoms were examined in 813 healthy siblings of patients with a non-affective psychotic disorder, 822 patients and 527 healthy controls. Depressive episodes meeting DSM-IV-TR criteria (lifetime) and depressed mood (lifetime) were assessed with the Comprehensive Assessment of Symptoms and History (CASH) in all three groups. In the patient group, the severity of positive and negative psychosis symptoms was assessed with the CASH. In the siblings and healthy controls, the severity of subclinical psychosis symptoms was assessed with the Community Assessment of Psychic Experiences (CAPE). Patients reported more lifetime depressed mood and more depressive episodes than both siblings and controls. Siblings had a higher chance of meeting lifetime depressive episodes than the controls; no significant differences in depressed mood were found between siblings and controls. In all three groups the number and duration of depressive symptoms were associated with (sub)clinical negative symptoms. In the patients and siblings the number of depressive symptoms was furthermore associated with (sub)clinical positive symptoms. Finally, lifetime depressed mood showed familial clustering but this clustering was absent for lifetime depressive episodes. These findings suggest that a co-occurring genetic vulnerability for both depressive and psychotic symptomatology exists on a clinical and a subclinical level.

The association between unequal parental treatment and the sibling relationship in Finland: The difference between full and half-siblings.

Studies have shown that unequal parental treatment is associated with relationship quality between siblings. However, it is unclear how it affects the relationship between full and half-siblings. Using data from the Generational Transmissions in Finland project (n = 1,537 younger adults), we study whether those who have half-siblings perceive more unequal parental treatment than those who have full siblings only. In addition, we study how unequal parental treatment is associated with sibling relationship between full, maternal, and paternal half-siblings. First, we found that individuals who have maternal and/or paternal half-siblings are more likely to have encountered unequal maternal treatment than individuals who have full siblings only. Second, we found that unequal parental treatment impairs full as well as maternal and paternal half-sibling relations in adulthood. Third, unequal parental treatment mediates the effect of genetic relatedness on sibling relations in the case of maternal half-siblings, but not in the case of paternal half-siblings. After controlling for unequal parental treatment, the quality of maternal half-sibling relationships did not differ from that of full siblings, whereas the quality of paternal half-sibling relationships still did. Fourth, the qualitative comments (n = 206) from the same population reveal that unequal parental treatment presents itself several ways, such as differential financial, emotional, or practical support.

Sibling relationship quality and psychosocial outcomes among adult siblings of individuals with autism spectrum disorder and individuals with intellectual disability without autism.

2017-03-01

Research on adult typically-developing (TD) siblings of individuals with developmental disabilities remains limited, and outcomes for TD siblings appear to vary widely. For the current study, 82 adult TD siblings of individuals with autism spectrum disorder (ASD) or intellectual disability (ID) completed questionnaires about themselves and their affected sibling. Results of this study suggest that the attitudes possessed by adult TD siblings are important to consider when understanding adult TD sibling outcomes. Specifically, data indicate that higher levels of positive sibling relationship attitudes are related to TD siblings providing more aid/support to their sibling with a disability, along with having higher levels of general life satisfaction, and negatively related to levels of stress and depressive symptoms among TD siblings. Consistent with previous child research, siblings of individuals with ASD reported fewer positive sibling relationship attitudes compared to siblings of individuals with ID. Finally, group membership related to aid provided, depressive symptoms, and stress of TD siblings indirectly through sibling relationship attitudes. Overall, results indicate that sibling relationship attitudes may be particularly important to consider when conceptualizing sibling relationships when one sibling has an intellectual or developmental disability.

2009-01-01

Recent research has shed new light on individual development during the early adulthood years, yet few investigators have examined sibling relationships during this stage of life. These relationships undergo transformations as individuals enter adult roles and orient their lives towards friends and romantic partners and establish independence from parents and siblings. This review examines major life events and role transitions such as leaving home, completing school, obtaining employment, getting married, and having children that influence individuals and their sibling relationships. In addition, the review considers how sibling relationships may affect individuals during the transition to adulthood, and considers the context of family and culture. The article concludes with suggestions for future research on sibling relationships during early adulthood and beyond. PMID:20700389

Postdoctoral training is a typical step in the course of an academic career, but very little is known about postdoctoral researchers (PDRs) working in the UK. This study used an online survey to explore, for the first time, relevant environmental factors which may be linked to the research output of PDRs in terms of the number of peer-reviewed articles per year of PDR employment. The findings showed reliable links between the research output and research institutions, time spent as PDR, and parental education, whereas no clear links were observed between PDRs' output and research area, nationality, gender, number of siblings, or work environment. PDRs based in universities tended to publish, on average, more than the ones based in research centres. PDRs with children tended to stay longer in postdoctoral employment than PDRs without children. Moreover, research output tended to be higher in PDRs with fathers educated at secondary or higher level. The work environment did not affect output directly, but about 1/5 of PDRs were not satisfied with their job or institutional support and about 2/3 of them perceived their job prospects as "difficult". The results from this exploratory study raise important questions, which need to be addressed in large-scale studies in order to understand (and monitor) how PDRs' family and work environment interact with their research output-an essential step given the crucial role of PDRs in research and development in the country.

2016-12-01

The aim of this study was to describe a Neuman Systems Model-guided study of perceptions of family stressors experienced by adult siblings who share caregiving for their parents and the influence of these stressors on adult siblings' relationships. The task of providing informal care for disabled parents is often shared by adult siblings. Family stressors experienced as part of caregiving may affect the sibling relationship. A mixed-method study design was used. Data were collected during 2013-2014 from 84 adult sibling caregivers. Seventy-two caregivers provided quantitative data for the Lifespan Sibling Relationship Scale and the Zarit Burden Scale and 79 provided qualitative data for the open-ended question. Adult siblings experienced mild-to-moderate levels of burden from family stressors when they share parental caregiving. The amount of burden from intra-family stressors was negatively related to the adult sibling relationship. Beneficial and noxious stressors were evident in the participants' responses to an open-ended question. The health of the parents affected the lives of adult siblings in both negative and positive ways. Although the majority of the adult siblings expressed a willingness to care for their parent(s) in an attempt to reciprocate the care, they had received from them, challenges emerged from dealing with family stressors. © 2016 John Wiley & Sons Ltd.

2003-01-01

Studied here were the links between sibling differences in trajectories of change in the qualities of parent-child relationships and the qualities of sibling relationships across a 2-year period in adolescence. Participants were first- and second-born siblings (M age = 14.94 years for firstborns and M age = 12.46 years for secondborns) from 185 predominantly White, working and middle-class families. In home interviews, siblings reported on their dyadic family relationships. For reports of parent-child warmth but not parent-child conflict, results were consistent with sibling differentiation theory: Increasing differences between siblings over time in parent-child warmth were linked to trajectories of increasing warmth and decreasing conflict in the sibling relationship as reported by firstborns, and increasing warmth in the sibling relationship as reported by secondborns. The findings support the view that sibling differentiation may be a strategy for managing sibling conflict and rivalry.

1990-10-01

Children in grades 3, 6, 9, and 12 were administered the Sibling Relationship Questionnaire. Relationships were rated as progressively more egalitarian across the 4 grade groups, with adolescents reporting less dominance and nurturance by their older siblings than younger participants. Adolescents also reported less companionship, intimacy, and affection with siblings than younger participants reported. Levels of perceived conflict with younger siblings were moderately high across all 4 grades, whereas ratings of conflict with older siblings were progressively lower across the 4 grades. The findings suggested that sibling relationships: (a) become more egalitarian and less asymmetrical with age, (b) become less intense with age, and (c) encompass experiences that are partially determined by the child's standing in the family constellation.

Siblings of individuals with autism or Down syndrome: effects on adult lives.

2007-09-01

In this study, we examine instrumental and affective involvement in the sibling relationship for adults who have a brother or sister with an autism spectrum disorder (ASD) or Down syndrome (DS). We ask three research questions: (1) How do adult siblings of individuals with ASD differ from siblings of individuals with DS in their assessment of the quality of the sibling relationship and their experience of growing up with a brother or sister with a disability? (2) Are there gender effects on the sibling relationship and sibling experience in these two groups? (3) Which factors are predictive of variation in the sibling relationship for siblings of adults with ASD or DS? Data from 154 siblings who participated in two linked longitudinal studies were used. Seventy-seven siblings with a brother or sister with ASD were matched by age and gender to 77 siblings with a brother or sister with DS. The siblings in each group were between 21 and 56 years of age and over half were sisters. Siblings completed questionnaires on instrumental and affective involvement with their brother or sister with ASD or DS, the impact of growing up with a brother or sister with a disability on their lives, and their coping skills and feelings of pessimism. Compared with the siblings of adults with DS, siblings of adults with ASD had less contact with their brother or sister, reported lower levels of positive affect in the relationship, felt more pessimistic about their brother or sister's future, and were more likely to report that their relationships with their parents had been affected. For siblings of adults with ASD, a closer sibling relationship was observed when the sibling had lower educational levels, lived closer to the brother or sister with ASD, used more problem-focused coping strategies, and when his or her brother or sister with ASD had higher levels of functional independence. In contrast, for siblings of adults with DS, a closer sibling relationship was observed when the

Mother-Child Relationship in Youths with Attention-Deficit Hyperactivity Disorder and their Siblings.

Despite impaired mother-child interactions noted in youth with attention-deficit/hyperactivity disorder (ADHD), there is no such information for their siblings. This study aimed to test whether the affected and unaffected siblings, like youth with ADHD, also encountered impaired mothering and mother-child relationships as compared to typically developing youth (TD). The sample consisted of 122 probands (107 males, 87.7 %), aged 10-16, with DSM-IV ADHD, 44 affected (26 males, 59.1 %) and 78 unaffected (28 males, 35.9 %) siblings, and 122 TD youth. Both participants and their mothers received psychiatric interviews (K-SADS-E) about the participants and reported maternal parenting style, mother-child interactions and child behavioral problems at home. Based on both reports, probands with ADHD and affected siblings (only youth report) had more impaired relationships, more behavioral problems at home, and less perceived family support than unaffected siblings and TD youth. Probands with ADHD had higher maternal authoritarian control than unaffected siblings. The findings suggest that impaired mothering, mother-child interactions, and family support are related to the presence of ADHD diagnosis in both probands and their affected siblings.

Infection with Helicobacter pylori (H. pylori) is acquired mainly in childhood, with studies demonstrating this is related to living conditions. Effects of sibling number and birth order on prevalence of infection have not been extensively studied. The authors performed a cross-sectional survey of adults, aged between 50 and 59 years, previously involved in a community-screening programme for H. pylori in Leeds and Bradford, UK. Prevalence of H. pylori was assessed at baseline with urea breath test. All individuals who were alive, and could be traced, were contacted by postal questionnaire in 2003 obtaining information on number of siblings and birth order. Data concerning childhood socioeconomic conditions were stored on file from the original study. 3928 (47%) of 8407 original participants provided data. Prevalence of infection increased according to sibling number (20% in those with none vs 63% with eight or more). Controlling for childhood socioeconomic conditions and birth order using multivariate logistic regression, infection odds were substantially increased with three siblings compared with none [odds ratio (OR) 1.51; 95% confidence interval (CI) 1.06-2.15], and a gradient of effect continued up to eight or more siblings (OR 5.70; 95% CI 2.92-11.14). Odds of infection also increased substantially with birth order, but the positive gradient disappeared on adjustment for sibling number and childhood socioeconomic conditions. : In this cross section of UK adults, aged 50-59 years, sibling number in the household, but not birth order, was independently associated with prevalence of H. pylori infection.

  Although many children grow up with more than one sibling, we do not yet know if sibling dyads within families show similarities to one another on sibling affection and hostility. In the present study the hypotheses were tested that (a) there will be significant between family variation in change in sibling affection and hostility and (b) this between family variation will be explained by maternal affective climate, operationalized as positive and negative ambient parenting, differential parenting and maternal malaise.   A general population sample of families with single and multiple sibling dyads were visited twice, 2 years apart. Up to 2 children in a family acted as informants; 253 relationships were rated in 118 families. A cross-classified, multilevel model was fit to separate between-family and within-family variance in sibling relationships while simultaneously controlling for informant and partner influences.   Thirty-seven percent of the variance in change in sibling affection and 32% of the variance in change in sibling hostility was between family variance. The measured maternal affective climate including, maternal malaise and maternal ambient and differential hostility and affection explained between family differences.   Sibling relationship quality clusters in families and is partly explained by maternal affective climate. © 2011 The Authors.

This study investigates the new phenomenon of parents of donor offspring searching for and contacting their child's 'donor siblings' (i.e. donor offspring conceived by the same donor) and donor. Online questionnaires were completed by 791 parents (39% lone-mother, 35% lesbian-couple, 21% heterosexual-couple, 5% non-specified) recruited via the Donor Sibling Registry; a US-based international registry that facilitates contact between donor conception families who share the same donor. Data were collected on parents' reasons for searching for their child's donor siblings and/or donor, the outcome of these searches and parents' and their child's experiences of any resulting contact. Parents' principal motivation for searching for their child's donor siblings was curiosity and for their donor, enhancing their child's sense of identity. Some parents had discovered large numbers of donor siblings (maximum = 55). Most parents reported positive experiences of contacting and meeting their child's donor siblings and donor. This study highlights that having access to information about a child's donor origins is important for some parents and has potentially positive consequences. These findings have wider implications because the removal of donor anonymity in the UK and elsewhere means that increasing numbers of donor offspring are likely to seek contact with their donor relations in the future.

  Sibling relationships are among the most unique social connections, significantly affecting psychosocial adjustment. Previous reviews in the fields of chronic illness and disability have concluded that unaffected siblings of children with long-term conditions are at risk of poorer psychological functioning as a consequence. Much research has investigated the psychosocial impact of CL/P on affected individuals and their parents, yet comparatively little is known about the impact on other close family members.   To gain a better understanding of the experience of unaffected siblings of children born with CL/P, with a view to informing service provision and support.   Individual qualitative interviews conducted over the telephone/Internet with five siblings and eight parents, including five sibling-parent pairs from the same family.   Thematic analysis identified three key themes applicable across both parent and sibling interviews: perceptions of positive and negative impacts, factors affecting the degree of impact, and support for families.   This study provides insight into a population that is often overlooked in the context of cleft care. The analysis identified a number of sibling support and information needs, along with suggestions of how to incorporate support for siblings in practice. The findings suggest that an inclusive approach to health care encompassing all members of the family is essential for optimal familial adjustment.

[The situation of siblings of mentally ill people].

PubMed

Schmid, R; Spiessl, H; Cording, C

2005-12-01

The purpose of this article is to provide an overview of the current research regarding the situation of mentally ill persons. The relevant literature was identified by means of a computerized MEDLINE search on the years 1996 - 2004 with the key words "sibling" and "mentally ill"/"chronically ill"/"psychiatric disorder" (631 articles). Also the related articles in the MEDLINE search were viewed. Finally 170 articles of journals and books were included in the review. The situation of siblings of psychiatric ill has manifold aspects, which can be classified into the following categories: Burdens due to the relationship to the ill sibling, burdens because of the relations to the shared parents and other family members, and burdens in the daily life of the siblings due to the illness of his/her sibling. On the other side there are rewards and positive developments in their life because of the illness of the sibling. Personal variables like sex, family size and age at onset of the illness are an influence on the experience of the sibling. The revealed burdens of the affected siblings require necessary answers by political representatives, professionals in and outside a clinic, and the involved families.

Sibling popularity: A moderator of sibling influence for adolescent substance use.

PubMed

Wallace, Lacey N

Sibling substance use is a known correlate of adolescent substance use. Yet, not all siblings are equally influential. Sibling influence has been found to vary by age gap, sex, and birth order. Little research, however, has investigated whether siblings' peer context is also a source of variation. The present study tested whether more popular siblings were more influential for adolescent use of cigarettes, alcohol, and marijuana. Data were obtained from sibling pairs in the National Longitudinal Study of Adolescent Health. Findings indicate that older siblings have more influence on younger sibling marijuana use when they have more friends. These findings contribute to prior work examining which siblings are more influential and highlight the need to consider siblings as part of a greater peer context.

Quality of life of unaffected siblings of children with chronic neurological disorders.

To study quality of life (QoL) of the siblings of children with chronic neurological disorders. Between 1st August and 30th September, 2013, 50 children aged 12-18 y, whose child sibling was suffering from a chronic neurological disorder, were enrolled (Study group). Fifty age- and sex- matched siblings of apparently non-neurologically affected children were enrolled as controls (Control group). Those with more than one affected child or any affected adult in the family were excluded. QoL was assessed by a validated version of the WHOQOL-BREF in Hindi, and QoL was compared between cases and controls. The disorders in the index cases included cerebral palsy, 18 (15 with epilepsy); autism, 15; mental retardation, 12 and epilepsy, 5. The QoL in all domains was significantly poorer in the study group as compared to the controls. 64% study group children had insufficient knowledge about their sibling's condition. More than 1/4th study subjects faced difficulties in studies, play or work. There was no difference among the groups with regard to number of siblings who had 'dropped from the school'. The QoL of unaffected siblings of children with chronic neurological disorders was significantly impaired. Health-workers may consider including older siblings of neurologically affected children during family-counseling sessions, to provide information and suggest coping strategies. This intervention is likely to improve the functioning of the family unit as a whole.

The association of sibling relationship and abuse with later psychological adjustment.

PubMed

Mackey, Amber L; Fromuth, Mary Ellen; Kelly, David B

2010-06-01

This study of 59 undergraduate men and 85 undergraduate women explored how defining emotional and physical sibling abuse affected the frequency of reported sibling abuse. In addition, the current study examined how the emotional context of the sibling relationship (i.e., rivalry and conflict) moderated the relationship between sibling abuse and later psychological adjustment (i.e., depression and anxiety). Respondents completed self-report questionnaires of sibling abuse (CTS2-SP), self-labeling of sibling abuse, quality of sibling relationships (SRQ), depression (CES-D), and anxiety (ZAS). Results indicated differences in frequency of reported abuse depending on how sibling abuse was defined. Also, there were no statistically significant correlations between the CTS2-SP and measures of psychological adjustment. Although self-labeling as emotionally abused correlated with later anxiety, the emotional context of the sibling relationship did not moderate this relationship.

Sibling rivalry.

PubMed

Leung, A K; Robson, W L

1991-05-01

Rivalry occurs between most, if not all, siblings to a varying degree. Rivalry may be manifested as a verbal or physical attack, frustration, persistent demands for attention, or as regressive phenomena. When handled properly, healthy competition among siblings will lead to the acquisition of social, interpersonal and cognitive skills that are important to the development of the child. Mismanagement of the competition may lead to psychological problems later in life. The appropriate spacing of children and the preparation of existing children for a new sibling help to reduce sibling rivalry. Family situations that will potentially lead to jealousy should be avoided. Parents should not make comparisons between siblings and favoritism should be avoided. When episodes of sibling rivalry develop, the cause rather than the manifestation of the rivalry should be treated. Patience, love, understanding, common sense, and humor are important parental skills necessary to minimize sibling rivalry.

Sibling relationship patterns and their associations with child competence and problem behavior.

Buist, Kirsten L; Vermande, Marjolijn

2014-08-01

The present study is the first to examine patterns in sibling relationship quality and the associations of these patterns with internalizing and externalizing problem behavior, as well as self-perceived competence, in middle childhood. Self-report questionnaires (e.g., Sibling Relationship Questionnaire, Self-Perception Profile for Children, Youth Self Report) were administered among 1,670 Dutch children (Mage = 11.40 years, SD = .83) attending 51 different Dutch schools. Three sibling relationship clusters were found: a conflictual cluster (low on warmth, high on conflict), an affect-intense cluster (above average on warmth and conflict), and a harmonious cluster (high on warmth, low on conflict). Sister pairs were underrepresented in the conflictual cluster and overrepresented in the harmonious cluster. Children with conflictual sibling relationships reported significantly more internalizing and externalizing problems, and lower academic and social competence and global self-worth, than children with harmonious sibling relationships. Children with affect-intense sibling relationships reported less aggression and better social competence than children with conflictual sibling relationships. Our findings indicate that it is fruitful to combine indices of sibling warmth and conflict to examine sibling relationship types. Relationship types differed significantly concerning internalizing and externalizing problems, but also concerning self-perceived competence. These findings extend our knowledge about sibling relationship types and their impact on different aspects of child adjustment. Whereas harmonious sibling relationships are the most beneficial for adjustment, sibling conflict mainly has a negative effect on adjustment in combination with lack of sibling warmth. Implications and future directions are discussed.

Early onset of diabetes in the proband is the major determinant of risk in HLA DR3-DQ2/DR4-DQ8 siblings.

Islet autoimmunity is initiated in infancy, and primary prevention trials require children at high genetic risk to be identified before autoantibodies appear. To inform screening strategies, we evaluated risks of autoimmunity and diabetes associated with HLA DR3-DQ2/DR4-DQ8 in U.K. families. Extended HLA haplotypes were determined in 2,134 siblings from the Bart's-Oxford Study followed to a median age of 22 years. Risks of diabetes and islet autoimmunity (more than two antibodies) were estimated by survival analysis. Of 138 informative DR3-DQ2/DR4-DQ8 siblings, 63% shared both haplotypes with their diabetic proband, 29% shared one, and 8% shared neither. In HLA-identical DR3-DQ2/DR4-DQ8 siblings, the cumulative risk of diabetes by age 15 was 17% (vs. 6% in those sharing one haplotype or none; P = 0.095). Risk varied, however, with the age at the onset of diabetes in the proband; the cumulative risk of autoimmunity and/or diabetes by age 15 was 61% in siblings of probands diagnosed when younger than 10 years old compared with only 4.7% in those diagnosed after age 10 years (P < 0.001). The age of the proband at diagnosis, but not HLA haplotype sharing, was an independent determinant of sibling risk. This suggests that non-HLA genes or epigenetic/environmental factors that accelerate the progression of type 1 diabetes in the proband strongly affect risk in siblings.

The siblings relationship of adolescents with and without intellectual disabilities.

PubMed

Begum, Gazi; Blacher, Jan

2011-01-01

The sibling relationship of adolescents with and without intellectual disabilities was examined. Participants were 70 sibling dyads--each dyad was comprised of one 12-year old adolescent with (N=23) or without intellectual disabilities (N=47). Sibling relationships, behavior problems, and social skills were assessed using mother reports. Results revealed three findings. First, for typically developing adolescents, mothers reported more warmth in the sibling relationship for opposite sex dyads. For adolescents with intellectual disabilities, mothers reported more warmth in the sibling relationship for same-sex dyads. Second, for typically developing adolescents, mothers reported more status/power differences when the sibling was younger than when the sibling was older. For adolescents with intellectual disabilities, birth order did not affect status/power in the sibling relationship. Third, for typically developing adolescents, conflict was related to internalizing behavior problems. For adolescents with intellectual disabilities, conflict was related to externalizing behavior problems. Implications, limitations, and future directions are discussed. Copyright © 2011 Elsevier Ltd.

Still the Favorite? Parents' Differential Treatment of Siblings Entering Young Adulthood.

Siennick, Sonja E

2013-08-01

This study examined within-family stability in parents' differential treatment of siblings from adolescence to young adulthood and the effect of differential treatment in young adulthood on grown siblings' relationship quality. The author used longitudinal data on parent - child and sibling relations from the sibling sample of the National Longitudinal Study of Adolescent Health ( N = 1,470 sibling dyads). Within-dyad fixed effects regression models revealed that the adolescent sibling who was closer to parents went on to be the young adult sibling who was closer to and received more material support from parents. Results from an actor - partner interdependence model revealed that differential parental financial assistance of young adult siblings predicted worse sibling relationship quality. These findings demonstrate the lasting importance of affect between parents and offspring earlier in the family life course and the relevance of within-family inequalities for understanding family relations.

Profiles of sibling bullying.

Skinner, Jessica A; Kowalski, Robin M

2013-05-01

Considerable research has been done on childhood bullying, including its antecedents and consequences. Yet, with all of the attention on bullying, particularly school bullying, sibling bullying has been vastly overlooked. Sibling bullying is a type of violence prevalent in the lives of most children, but little is known about the phenomenon. The purpose of this study was to profile sibling bullying by examining prevalence rates, the extent to which siblings perceive sibling bullying to be normative, and victim-perpetrator differences in perceptions of sibling bullying. Twenty-seven sibling pairs who wrote stories about personal experiences of sibling bullying and victimization completed questionnaires about these experiences and responded to their sibling partners' stories. Of the siblings surveyed, 78% reported being bullied by their sibling and 85% reported bullying their sibling during their childhood. This is far greater than published statistics on peer bullying. Not surprisingly, victims viewed sibling bullying more negatively than perpetrators. Sadly, there was a norm of acceptance of sibling bullying among most of the sibling pairs. Practical implications are discussed.

Little is known about whether siblings have similar or different eating behaviours or whether parents tailor their feeding practices to different siblings. The main objectives of the present study were to examine similarities and differences in child eating behaviours and parental feeding practices with siblings and to determine whether child eating behaviours and parental feeding practices differ depending on sibling concordant (i.e. both siblings overweight or healthy weight) or discordant (i.e. one sibling overweight and one sibling healthy weight) weight status. Cross-sectional, mixed-methods study. In-home visits were conducted by research staff. Surveys were conducted with parents and anthropometry was collected on parents and siblings. Children (n 88) aged 6-12 years (mean age 9 (sd 2) years), their parents (mean age 34 (sd 7) years) and near-age siblings (mean age 9 (sd 4) years) from diverse racial/ethnic and low-income households participated. Results indicated that siblings with higher BMI engaged in higher levels of emotional eating compared with siblings with lower BMI. Additionally, results indicated that when families had sibling dyads discordant on weight status, the sibling who was overweight had higher food enjoyment and lower levels of food satiety. Additionally, within siblings with discordant weight status, parents were more likely to use restrictive feeding practices with the overweight sibling and pressure-to-eat and encouragement-to-eat feeding practices with the healthy-weight sibling. Family-based childhood obesity interventions may need to assess for sibling weight status when researching the home environment and intervene with parents to avoid using restriction or pressure-to-eat feeding practices when siblings are discordant on weight status.

Siblings' experiences of having a brother or sister with autism and mental retardation: a case study of 14 siblings from five families.

PubMed

Benderix, Ylva; Sivberg, Bengt

2007-10-01

The aim of this study was to describe the present and past experiences of 14 siblings from five families in terms of having a brother or sister with autism and mental retardation. Personal interviews were conducted with the siblings before their brothers or sisters were moved to a newly opened group home. Qualitative content analysis was used for the analysis of the transcribed texts. The analysis resulted in seven content categories: precocious responsibility, feeling sorry, exposed to frightening behavior, empathetic feelings, hoping that a group home will be a relief, physical violence made siblings feel unsafe and anxious, and relations with friends were affected negatively. The conclusion is that these siblings' experiences revealed stressful life conditions. Counseling for the family and for siblings is recommended to help them deal with their feelings and problems. For the siblings in these five families, a group home was a relevant alternative as a temporary or permanent placement for the child with autism and mental retardation.

Despite high psychiatric comorbidities in adolescents with clinical diagnosis of attention-deficit hyperactivity disorder (ADHD), little is known about psychiatric comorbidities in their siblings. We investigated the psychiatric comorbid conditions in adolescents with ADHD, their siblings, and healthy control subjects from their school. The sample included 136 adolescent probands with ADHD according to the Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition (DSM-IV), diagnostic criteria; 136 siblings (47 affected and 89 unaffected) and 136 age- and sex-matched healthy school control subjects. All participants and their parents received the structured psychiatric interviews for current and lifetime DSM-IV psychiatric disorders of the participants. The rate of ADHD (34.6%) in the siblings of probands with ADHD was about 7 times higher than in the general population. Probands with ADHD were significantly more likely than unaffected siblings (OR 6.38; 95% CI 3.43 to 11.88) and healthy school control subjects (OR 9.60; 95% CI 5.31 to 17.34) to have a DSM-IV psychiatric disorder, including oppositional defiant disorder (ODD), conduct disorder (CD), tic disorders, major depressive disorder, specific phobia (more than control subjects only), nicotine use disorder, and sleep disorders. The affected siblings were significantly more likely than healthy school control subjects to have ODD, CD, specific phobia, and to have consumed alcohol (ORs ranging from 2.30 to 20.16). Our findings suggest that siblings of probands with ADHD have increased risks for ADHD and that the affected siblings have more psychiatric comorbidities than healthy school control subjects. It warrants early identification of ADHD symptoms and other psychiatric comorbid conditions as well in siblings of adolescents with ADHD.

Children affected by HIV and AIDS have significantly higher rates of mental health problems than unaffected children. There is a need for research to examine how social support functions as a source of resiliency for children in high HIV-prevalence settings such as South Africa. The purpose of this research was to explore how family social support relates to depression, anxiety, and post-traumatic stress (PTS). Using the ecological model as a frame, data were drawn from a 2011 cross-sectional study of 1380 children classified as either orphaned by AIDS and/or living with an AIDS sick family member. The children were from high-poverty, high HIV-prevalent rural and urban communities in South Africa. Social support was analyzed in depth by examining the source (e.g. caregiver, sibling) and the type (e.g. emotional, instrumental, quality). These variables were entered into multiple regression analyses to estimate the most parsimonious regression models to show the relationships between social support and depression, anxiety, and PTS symptoms among the children. Siblings emerged as the most consistent source of social support on mental health. Overall caregiver and sibling support explained 13% variance in depression, 12% in anxiety, and 11% in PTS. Emotional support was the most frequent type of social support associated with mental health in all regression models, with higher levels of quality and instrumental support having the strongest relation to positive mental health outcomes. Although instrumental and quality support from siblings were related to positive mental health, unexpectedly, the higher the level of emotional support received from a sibling resulted in the child reporting more symptoms of depression, anxiety, and PTS. The opposite was true for emotional support provided via caregivers, higher levels of this support was related to lower levels of all mental health symptoms. Sex was significant in all regressions, indicating the presence of moderation.

Bullying among siblings.

Parents are often concerned about repeated conflicts between their daughters and sons. However, there is little empirical research of sibling bullying. To conduct a review of existing studies of sibling bullying. Are there any associations between sibling bullying and peer bullying at school? What are the consequences of sibling bullying? Is there good justification why sibling bullying has been so neglected in research? Studies of sibling relationships were reviewed. Four quantitative studies were identified that report on both sibling and peer bullying. Sibling bullying is frequent with up to 50% involved in sibling bullying every month and between 16% and 20% involved in bullying several times a week. Experience of sibling bullying increases the risk of involvement in bullying in school. Both, bullying between siblings and school bullying make unique contributions to explaining behavioral and emotional problems. There is a clear dose-effect relationship of involvement of bullying at home and at school and behavioral or emotional problems. Those involved in both have up to 14 times increased odds of behavioral or emotional problems compared to those involved in only one context or not at all. The empirical evidence is limited and studies are mostly cross-sectional studies. Nevertheless, the review suggests that for those victimized at home and at school behavioral and emotional problems are highly increased. Sibling relationships appear to be a training ground with implications for individual well-being. Strengthening families and parenting skills and increasing sibling support is likely to reduce bullying and increase well-being.

Emotion regulation in context: the jealousy complex between young siblings and its relations with child and family characteristics.

PubMed

Volling, Brenda L; McElwain, Nancy L; Miller, Alison L

2002-01-01

Jealousy is a social emotion that has received little attention by developmental researchers. The current study examined sibling jealousy and its relations to child and family characteristics in 60 families with a 16-month-old toddler and an older preschool-age sibling. Sibling jealousy was elicited in social triads consisting of a parent (mother or father) and the two siblings. Positive marital relationship quality (i.e., love and relationship maintenance) was a particularly strong predictor of the older siblings' abilities to regulate jealousy reactions in the mother sessions. Younger siblings' jealous affect with mothers was linked to the child's temperament, whereas older siblings' jealous affect with mothers was related to the child's emotional understanding. Younger siblings displayed more behavioral dysregulation in the mother-sibling triads if there was greater sibling rivalry reported by mothers. Session order (i.e., which sibling was challenged first in the jealousy paradigm) had a strong effect on both the affect and behavioral dysregulation displayed by the older and younger siblings. Results are discussed with respect to the need for future research to consider social relationships as developmental contexts for young children's emotion regulation.

The role of siblings in identity development in adolescence and emerging adulthood.

2010-10-01

This study examined the role of siblings on identity formation in adolescence and emerging adulthood, using a three-wave longitudinal design. Measures of identity formation were filled out by 498 sibling dyads. Sibling effects differed as a function of age and gender configuration within the dyads. Controlled for age, earlier-born siblings reported the most advanced levels of identity formation, and later-born siblings the lowest. Positive relations between siblings' identity and changes in identity of respondents provided support for modeling processes between siblings. The identity of earlier-born same-sex siblings, in particular, tends to be important in influencing identity formation. Contrary to the expectations, differentiation processes between siblings did not appear to influence identity formation. It is apparent from this study that both the gender and birth order of siblings affect whether their own identity formation processes influence those of adolescents and emerging adults.

High rates of obsessive-compulsive symptoms (OCS) in schizophrenia require pathogenic explanations. Personality traits may represent risk and resiliency factors for the development of mental disorders and their comorbidities. The aim of the present study was to explore the associations between Five-Factor Model (FFM) personality traits and the liability for OCS in patients with psychotic disorders and in their un-affected siblings. FFM traits, occurrence and severity of OCS and (subclinical) psychotic symptoms were assessed in 208 patients and in 281 siblings. Differences in FFM traits between participants with vs. without comorbid OCS were examined and the predictive value of FFM traits on group categorization was evaluated. Associations between FFM traits and OCS severity were investigated. Patients and siblings with OCS showed significantly higher Neuroticism compared to their counterparts without OCS. Neuroticism was positively associated with higher OCS severity and significantly predicted group assignment in both patients and in siblings. Patients with comorbid OCS presented with lower scores on Extraversion and Conscientiousness. Higher Neuroticism, and to a lesser degree lower Extraversion and Conscientiousness might add to the vulnerability of patients with a psychotic disorder to also develop OCS. Future prospective studies are needed to elucidate proposed personality-psychopathology interrelations and possible mediating factors. Copyright © 2014 Elsevier Ireland Ltd. All rights reserved.

This study examined within-family stability in parents’ differential treatment of siblings from adolescence to young adulthood and the effect of differential treatment in young adulthood on grown siblings’ relationship quality. The author used longitudinal data on parent – child and sibling relations from the sibling sample of the National Longitudinal Study of Adolescent Health (N = 1,470 sibling dyads). Within-dyad fixed effects regression models revealed that the adolescent sibling who was closer to parents went on to be the young adult sibling who was closer to and received more material support from parents. Results from an actor – partner interdependence model revealed that differential parental financial assistance of young adult siblings predicted worse sibling relationship quality. These findings demonstrate the lasting importance of affect between parents and offspring earlier in the family life course and the relevance of within-family inequalities for understanding family relations.

Stuttering impacts on the child in a variety of ways, notably in terms of communicative impairment and psychosocial impact. In addition, the stuttering disorder has a holistic impact, affecting those with whom the child who stutters lives. Within the family constellation, the closest person to the individual who stutters is often their sibling. This study investigated the experiences of fluent siblings of children who stutter to examine the impact that stuttering may have on their lives. A mixed methods research design incorporated qualitative semi-structured interviews and quantitative questionnaires. The results of the qualitative investigation revealed four aspects of children's lives that were affected by having a sibling who stuttered: the relationship between siblings, the impact on the fluent sibling, the impact on the parent relationship with both children, and the impact on the sibling's relationship with others. Findings revealed that siblings of children who stutter exhibited strongly negative emotions, and differing levels of responsibility associated with their involvement in the actual stuttering management programme. Furthermore, for the fluent sibling, secondary to having a brother or sister who stuttered, communication with and attention from their parents was variable. The results of the quantitative component of the study revealed children who stutter and their siblings demonstrated significantly greater closeness, and concurrently, increased conflict and status disparity than did the control fluent sibling dyads. The parents of the experimental sibling dyads also demonstrated significantly greater partiality towards a child, namely the child who stuttered, than did the parents of the control sibling dyads. The reader will be able to: (1) identify the themes associated with having a sibling who stutters; (2) identify how the quality of the sibling relationship differs between sibling dyads that do and do not consist of a sibling who stutters; and

Objective To compare academic achievement in children with oral-facial clefts (OFC) with their unaffected siblings. Methods 256 children with OFC were identified from the Iowa Registry for Congenital and Inherited Disorders, and 387 unaffected siblings were identified from birth certificates. These data were linked to Iowa Testing Programs achievement data. We compared academic achievement in children with OFC with their unaffected siblings using linear regression models, adjusted for potential confounders. In post hoc analyses, we explored modifiers of siblings’ academic performance. Results Achievement scores were similar between children with OFC and their siblings. Children with cleft palate only were significantly more likely to use special education than their unaffected siblings. Siblings’ academic achievement was inversely related to distance in birth order and age from the affected child. Conclusion Children with OFC and their siblings received similar achievement scores. Younger siblings, in particular, may share a vulnerability to poor academic outcomes. PMID:24993102

To illuminate how within-family differences in achievement may emerge, this study examined sibling experiences in middle childhood as predictors of sibling differences in college graduation. First- and second-borns from 152 families reported on their experiences with siblings and parents at ages 11.80 (SD = 0.56) and 9.22 (SD = 0.90), respectively, and on their educational attainment at about age 26. Significant childhood predictors of sibling differences in college graduation status included low sibling warmth, fathers' differential time spent with siblings, and perceived unfair differential treatment by parents. Findings suggest long-term implications of early sibling dynamics for educational attainment and provided novel insights into families' role in achievement. © 2018 Society for Research in Child Development.

Differential parenting and sibling jealousy: Developmental correlates of young adults' romantic relationships

PubMed Central

Rauer, Amy J.; Volling, Brenda L.

2009-01-01

Data from a survey of 200 young adults assessed whether the early nonshared environment, specifically parental differential treatment, was associated with romantic relationship distress through its effects on sibling jealousy, attachment styles, and self-esteem. Individuals who received equal affection from their parents in comparison to their sibling reported equal jealousy between themselves and their sibling, had higher self-esteem, more secure attachment styles, and less romantic relationship distress. Receiving differential parental affection, regardless of whether the participant or their sibling was favored, was associated with more negative models of self and others, which in turn were associated with greater romantic relationship distress. Results indicate that early within-family experiences may be particularly relevant for later healthy romantic relationship functioning. PMID:19050748

Fullerton, J M; Totsika, V; Hain, R; Hastings, R P

2017-05-01

This study explored psychological adjustment and sibling relationships of siblings of children with life-limiting conditions (LLCs), expanding on previous research by defining LLCs using a systematic classification of these conditions. Thirty-nine siblings participated, aged 3-16 years. Parents completed measures of siblings' emotional and behavioural difficulties, quality of life, sibling relationships and impact on families and siblings. Sibling and family adjustment and relationships were compared with population norms, where available, and to a matched comparison group of siblings of children with autistic spectrum disorder (ASD), as a comparable 'high risk' group. LLC siblings presented significantly higher levels of emotional and behavioural difficulties, and lower quality of life than population norms. Their difficulties were at levels comparable to siblings of children with ASD. A wider impact on the family was confirmed. Family socio-economic position, time since diagnosis, employment and accessing hospice care were factors associated with better psychological adjustment. Using a systematic classification of LLCs, the study supported earlier findings of increased levels of psychological difficulties in siblings of children with a LLC. The evidence is (i) highlighting the need to provide support to these siblings and their families, and (ii) that intervention approaches could be drawn from the ASD field. © 2016 John Wiley & Sons Ltd.

Siblings exposed to intimate partner violence: linking sibling relationship quality & child adjustment problems.

2014-01-01

Although the majority of families that experience intimate partner violence (IPV) have more than one child, most research to date has focused upon a single child within these families. A significant body of research has indicated siblings play an important role in children's adjustment and well-being. To address this gap, the three main goals of the present study were to compare the adjustment of older and younger siblings exposed to IPV, to describe and compare the quality of these sibling relationships from multiple perspectives, and to investigate how sibling adjustment and relationship quality influence children's adjustment. Forty-seven sibling pairs and their mothers were recruited from the community. Mothers self-reported on their violent experiences using the Conflict Tactics Scale, and also estimated the length of time their children were exposed to IPV. Mothers and children completed assessments of child adjustment and the quality of sibling relationships. Observers also assessed the quality of sibling interaction. Results indicated that adjustment between siblings was highly inter-related. On average, mothers reported sibling relationships as less positive but also as less hostile than did siblings themselves. Higher levels of sibling hostility, lower levels of sibling warmth and higher levels of disengagement each significantly predicted child adjustment; however, these effects were predicated upon the adjustment of the other sibling. The sibling relationships of children exposed to IPV made a difference in their individual adjustment, and their adjustment issues influenced how they feel about and interacted with their sibling. Sibling hostility played a stronger role in adjustment issues than sibling warmth. The nature of sibling influences and the direction of future research were discussed. Copyright © 2013 Elsevier Ltd.

Don't forget the siblings: School-aged siblings of children presenting to mental health services show at-risk patterns of attachment.

PubMed

Kozlowska, Kasia; Elliott, Bronwen

2017-04-01

Family therapists understand that children presenting for treatment are often bearers of symptoms signalling relational problems within the family system. Rather than addressing the children's symptoms in isolation, family therapists typically take those relational problems as their starting point in therapy. This study used the School-aged Assessment of Attachment (SAA) to assess the self-protective (attachment) strategies of the siblings of children presenting for psychiatric evaluation and also of the siblings of control children drawn from the normative population. Siblings of children in the clinical group were much more likely than siblings of control children to use at-risk self-protective strategies and to have markers suggestive of unresolved loss or trauma. School-aged siblings were found to use a broad range of strategies, and the pattern of change from first born to later born involved either a reversal of strategy or a shift to a more complex strategy. The study highlights that siblings of children presenting to mental health services are significantly affected by family relational stress. A family systems approach to assessment, one that enquires about the wellbeing of all family members, will ensure that the emotional needs of siblings are also addressed during the therapy process.

The study was carried out with the aim of determining the factors affecting and to evaluate anxiety situations and self-esteem of children with and without mentally retarded siblings. The sampling included 227 healthy children: 108 of them have mental retarded sibling and 119 of them do not have mental retarded sibling. The context of this study consisted of 15-18 year of age healthy children with mentally retarded siblings and 15-18 year of aged healthy children having at least one sibling between the dates February 15(st) and June 26(st) 2010. Personal Information Form, Rosenberg Self-Esteem Scale and Trait Anxiety Scale were used. It was found out that trait anxiety of 17-18 aged of children with mental retarded sibling (47.04 ± 7.3) was higher than that of the children without mental retarded siblings (44.05 ± 11.23) (P < 0.05). It was observed that self-esteem of children with mentally retarded sibling was not affected from the handicap of their siblings (P > 0.05). Trait anxiety score averages of children with mentally retarded sibling and experience some difficulties due to his or her siblings's handicap (47.00 ± 7.76) were found higher than those of those of the children without any problem with the environment (42.61 ± 7.48) (P < 0.05). Although the average score of trait anxiety and self-esteem in both groups were not significant different, score of trait anxiety for children with mentally disabled siblings was higher in comparison. It was concluded that anxiety of children with and without mentally retarded siblings increased as self-esteem of these children decreased.

This study was conducted to identify a potential neuroendophenotype for autism using diffusion tensor imaging. Whole-brain, voxel-based analysis of fractional anisotropy was conducted in 50 children: 19 with autism, 20 unaffected siblings, and 11 controls. Relative to controls, participants with autism exhibited bilateral reductions in fractional anisotropy across association, commissure, and projection fibers. The most severely affected tracts included the uncinate fasciculus, forceps minor, and inferior fronto-occipital fasciculus. Unaffected siblings also exhibited reductions in fractional anisotropy, albeit less severe with fewer affected tracts, sparing the uncinate fasciculus and forceps minor. These results suggest the presence of a neuroendophenotype for autism.

Autism is a highly heritable and clinically heterogeneous neuropsychiatric disorder that frequently co-occurs with other psychopathologies, such as attention-deficit/hyperactivity disorder (ADHD). An approach to parse heterogeneity is by forming more homogeneous subgroups of autism spectrum disorder (ASD) patients based on their underlying, heritable cognitive vulnerabilities (endophenotypes). Emotion recognition is a likely endophenotypic candidate for ASD and possibly for ADHD. Therefore, this study aimed to examine whether emotion recognition is a viable endophenotypic candidate for ASD and to assess the impact of comorbid ADHD in this context. A total of 90 children with ASD (43 with and 47 without ADHD), 79 ASD unaffected siblings, and 139 controls aged 6-13 years, were included to test recognition of facial emotion and affective prosody. Our results revealed that the recognition of both facial emotion and affective prosody was impaired in children with ASD and aggravated by the presence of ADHD. The latter could only be partly explained by typical ADHD cognitive deficits, such as inhibitory and attentional problems. The performance of unaffected siblings could overall be considered at an intermediate level, performing somewhat worse than the controls and better than the ASD probands. Our findings suggest that emotion recognition might be a viable endophenotype in ASD and a fruitful target in future family studies of the genetic contribution to ASD and comorbid ADHD. Furthermore, our results suggest that children with comorbid ASD and ADHD are at highest risk for emotion recognition problems.

Research on the experiences of siblings of individuals with ASD and the quality of their sibling relationships has yielded mixed results. The present study examined the significance of parent- versus child-report of both positive and negative behaviors exhibited by siblings and their brothers and sisters with ASD within sibling dyads. Findings indicated that siblings were more positive in their assessment of the sibling relationship than were their parents. Siblings exhibited more positive behaviors within the sibling relationship than did their brothers and sisters with ASD, and were recipients of aggression. These findings are consistent with prior research suggesting that siblings tend to take on a caretaking role, and point to important targets for intervention.

Retrospective data from 1,821 women and 1,064 men with one or more siblings, provided anonymously using a computer-assisted self-interview, were used to identify risk factors for sibling incest (SI); 137 were participants in SI. In order of decreasing predictive power, the risk factors identified by the multiple logistic regression analysis included ever having shared a bed for sleeping with a sibling, parent-child incest (PCI), family nudity, low levels of maternal affection, and ever having shared a tub bath with a sibling. The results were consistent with the idea that SI in many families was the cumulative result of four types of parental behaviors: (a) factors that lower external barriers to sexual behavior (e.g., permitting co-sleeping or co-bathing of sibling dyads), (b) factors that encourage nudity of children within the nuclear family and permit children to see the parent's genitals, (c) factors that lead to the siblings relying on one another for affection (e.g., diminished maternal affection), and (d) factors that eroticize young children (e.g., child sexual abuse [CSA] by a parent). Thirty-eight of the 137 SI participants were participants in coerced sibling incest (CSI). In order of decreasing predictive power, risk factors for CSI identified by multiple logistic regression analysis included ever having shared a bed for sleeping with a brother, PCI, witnessing parental physical fighting, and family nudity. SI was more likely to have been reported as CSI if the sibling had touched the reporting sibling's genitals, and less likely to have been reported as CSI if the siblings had shared a bed. © The Author(s) 2014.

OBJECTIVES: Although many injuries happen when school age children are away from home and in the company of other children, we know surprisingly little about interpersonal influences on children's risk taking decisions. The aim of the present study was to examine the influence of older siblings' persuasive appeals on young children's decisions about engaging in behaviours that could threaten their physical safety. METHODS: Forty same sex sibling pairs participated. Children were shown drawings of play scenes (bicycling, river crossing, and sledding), with each depicting lower and higher risk paths of travel. Children of 8 years made initial decisions as to which paths they would take. Subsequently, their older sibling acted as a confederate and tried to persuade them to change their decisions. RESULTS: After the appeals of older siblings, younger children significantly shifted their decisions: choices of less risky paths replaced the initial selection of more risky paths, and vice versa. A positive sibling relationship was predictive of younger siblings' decision changes. Boys and girls were equally effective in persuasion but they did so using different types of arguments, with boys communicating primarily appeals to fun and girls emphasizing appeals to safety. CONCLUSIONS: These findings highlight the effect that older siblings can have on risk taking decisions of younger siblings. Accordingly, they document the importance of considering the interpersonal context of risk taking when designing interventions to reduce injuries among elementary schoolchildren. Images PMID:9113843

Context The death of a child from cancer affects the entire family. Little is known about the long-term psychosocial outcomes of bereaved siblings. Objectives To describe: (1) the prevalence of risky health-behaviors, psychological distress, and social support among bereaved siblings; (2) potentially modifiable factors associated with poor outcomes. Methods Bereaved siblings were eligible for this dual-center, cross-sectional, survey-based study if they were ≥16 years-old and their parents had enrolled in one of three prior studies about caring for children with cancer at end of life. Linear regression models identified associations between personal perspectives before, during, and after the family's cancer experience and outcomes (health-behaviors, psychological distress, and social support). Results Fifty-eight siblings completed surveys (62% response rate). They were approximately 12 years bereaved, with a mean age of 26 years at the time of the survey (SD=7.8). Anxiety, depression, and illicit substance use increased during the year following their brother/sister's death, but then returned to baseline. Siblings who reported dissatisfaction with communication, poor preparation for death, missed opportunities to say “goodbye,” and/or a perceived negative impact of the cancer experience on relationships tended to have higher distress and lower social support scores (p<0.001-0.031). Almost all siblings reported their loss still affected them; half stated the experience impacted current educational and career goals. Conclusion How siblings experience the death of a child with cancer may impact their long-term psychosocial well-being. Sibling-directed communication and concurrent supportive care during the cancer experience and the year following sibling death may mitigate poor long-term outcomes. PMID:24880001

Theory of mind (ToM) impairment has been consistently demonstrated in patients with schizophrenia, but whether ToM impairments exist in unaffected siblings of patients with schizophrenia remains unclear. Few studies have examined the affective and cognitive components of ToM in schizophrenia. This study aimed to examine whether ToM impairments exist in patients with first-episode schizophrenia and their unaffected siblings, and whether there is any dissociation between the affective and cognitive components of ToM. We adopted a family-based case-control design. Participants were 41 patients with first-episode schizophrenia, 43 unaffected siblings, and 42 healthy controls. The Yoni Task which measures the participants' ability to understand first- and second-order affective versus cognitive ToM and the Faux Pas Task which taps into integration of the affective and cognitive components of ToM were administered. Multivariate and univariate ANCOVAs were used to examine the group differences in ToM, while controlling for other neurocognitive functions. Compared with controls, patients with schizophrenia and their unaffected siblings performed poorer on the Faux Pas Task (p<0.001), with siblings having intermediate performance between patients and controls. Patients with schizophrenia performed worse than controls on second-order affective condition of the Yoni Task (p=0.004), but their unaffected siblings did not (p=0.063). We did not find any significant Group-by-Condition interaction in the Yoni Task (p=0.358). Patients with first-episode schizophrenia and their unaffected siblings exhibit ToM impairments, but no dissociation between affective and cognitive component of ToM was found. Our findings support the notion that ToM deficit may be a trait marker of schizophrenia. Copyright © 2014 Elsevier B.V. All rights reserved.

When there is a child with cancer in the family, the entire family is affected. Childhood cancer is a highly stressful experience that affects the adaptation of family member to psychosocial tasks. Many of the family stresses and changes that accompany childhood cancer have a severe impact on siblings. An understanding of the experiences and needs of such siblings is vital. The aim of this study was to understand the nature of the overall experiences of a child who has a brother or sister with cancer. Searches of CINAHL, MEDLINE/PubMed, Science Direct, Scopus, Eric, and Chinese electronic periodical services identified 10 qualitative studies that were published between 1960 and 2013. An appraisal of the primary studies was carried out using the Joanna Briggs Institute Qualitative Assessment and Review Instrument. Siblings of children with cancer were found to have experienced 4 themes: (1) the disintegration of life, (2) marginalization within their family relationships, (3) self-transcendence during the normalization of family relationships, and (4) maintenance of family integrity and family normality. Siblings of children with cancer experience a great deal of chaos in their family life, and this affects their self-esteem and family intimacy. Being with the sick child may help siblings understand the sick child's suffering and experiences. The findings of this review provide evidence to help health professionals to assess the needs of the siblings to enhance their sense of self within the family. Providing the siblings with suitable resources should result in better adjustment.

2012-03-01

The aim of this meta-analysis was to provide an up-to-date review of the literature to enhance our understanding of how chronic health conditions (CHCs) affect siblings, both positively and negatively. PsycINFO and Medline were systematically searched. Inclusion criteria were as follows: (a) peer-reviewed, empirical research report; (b) sample n ≥ 10; and (c) reports statistics on siblings' internalizing problems, externalizing problems, and/or positive self-attributes. Overall, there was a significant small negative effect of CHCs on siblings (d(+) = -.10). Siblings of children with CHCs had more internalizing problems (d(+) = .17), more externalizing problems (d(+) = .08), and less positive self-attributes (d(+) = -.09) than comparisons. Older siblings and siblings of children with life-threatening and/or highly intrusive CHCs were more at risk for psychological problems. This study identified several mechanisms through which CHCs affect siblings. Future research should focus on parent-child dynamics and the longitudinal development of positive self-attributes and internalizing problems as well as on identifying what works in services for siblings of children with CHCs.

Disturbances in sleep and waking patterns are highly prevalent during mood episodes in bipolar disorder. The question remains whether these disturbances persist during phases of euthymia and whether they are heritable traits of bipolar disorder. The current study investigates objective sleep measures in a large sample of bipolar I patients, non-affected siblings and controls. A total of 107 bipolar disorder I patients, 74 non-affected siblings, and 80 controls were included. Sleep was measured with actigraphy over the course of 14 days. Seven sleep parameters were analyzed for group differences and their relationship with age at onset, number of episodes and psychotic symptoms using linear mixed model analysis to account for family dependencies. Patients had a longer sleep duration and later time of sleep offset compared to the non-affected siblings but these differences were entirely attributable to differences in mood symptoms. We found no difference between patients and controls or siblings and controls when the analyses were restricted to euthymic patients. None of the bipolar illness characteristics were associated with sleep. Medication use was not taken into account which may have influenced our findings and controls were younger compared to non-affected siblings. In the largest study to date, our findings suggest that recovered bipolar I patients and their siblings do not experience clinically significant sleep disturbances. Sleep disturbances are primarily a reflection of current mood state, but are unrelated to the course of the disorder. Copyright © 2016 Elsevier B.V. All rights reserved.

What makes siblings different? The development of sibling differences in academic achievement and interests.

Jensen, Alexander C; McHale, Susan M

2015-06-01

To illuminate processes that contribute to the development of sibling differences, this study examined cross-lagged links between parents' beliefs about sibling differences in academic ability and differences between siblings' grade point averages (GPAs), and cross-lagged links between differences in siblings' GPAs and sibling differences in academic interests. Data were collected from mothers, fathers, firstborn youth (M age at Time 1 = 15.71, SD = 1.07), and secondborn youth (M age at Time 1 = 13.18, SD = 1.29) from 388 European American families on 3 annual occasions. Findings revealed that, after controlling for siblings' average grades and prior differences in performance, parents' beliefs about sibling differences in academic ability predicted differences in performance such that youth rated by parents as relatively more competent than their sibling earned relatively higher grades the following year. Siblings' relative school performance, however, did not predict parents' beliefs about differences between siblings' competencies. Further, after controlling for average interests and grades, sibling differences in GPA predicted differences in siblings' interests such that youth who had better grades than their siblings reported relatively stronger academic interests the following year. Differences in interest, however, did not predict sibling differences in GPA. Findings are discussed in terms the role of sibling dynamics in family socialization.

This study asks brothers and sisters about their feelings and perceptions toward their sibling with Down syndrome. We analyzed valid and reliable surveys from 822 brothers and sisters whose families were on the mailing lists of six non-profit Down syndrome organizations around the country. More than 96% of brothers/sisters that responded to the survey indicated that they had affection toward their sibling with Down syndrome; and 94% of older siblings expressed feelings of pride. Less than 10% felt embarrassed, and less than 5% expressed a desire to trade their sibling in for another brother or sister without Down syndrome. Among older siblings, 88% felt that they were better people because of their siblings with Down syndrome, and more than 90% plan to remain involved in their sibling’s lives as they become adults. The vast majority of brothers and sisters describe their relationship with their sibling with Down syndrome as positive and enriching. PMID:21910244

Purpose: Studies of later-life families have revealed that sibling tension often increases in response to parents’ need for care. Both theory and research on within-family differences suggest that when parents’ health declines, sibling relations may be affected by which children assume care and whether siblings perceive that the parent favors some offspring over others. In the present study, we explore the ways in which these factors shape sibling tension both independently and in combination during caregiving. Design and Methods: In this article, we use data collected from 450 adult children nested within 214 later-life families in which the offspring reported that their mothers needed care within 2 years prior to the interview. Results: Multilevel analyses demonstrated that providing care and perceiving favoritism regarding future caregiving were associated with sibling tension following mothers’ major health events. Further, the effects of caregiving on sibling tension were greater when perceptions of favoritism were also present. Implications: These findings shed new light on the conditions under which adult children are likely to experience high levels of sibling tension during caregiving. Understanding these processes is important because siblings are typically the individuals to whom caregivers are most likely to turn for support when assuming care of older parents, yet these relationships are often a major source of interpersonal stress.

The death of a child from cancer affects the entire family. Little is known about the long-term psychosocial outcomes of bereaved siblings. To describe 1) the prevalence of risky health behaviors, psychological distress, and social support among bereaved siblings and 2) potentially modifiable factors associated with poor outcomes. Bereaved siblings were eligible for this dual-center, cross-sectional, survey-based study if they were 16 years or older and their parents had enrolled in one of three prior studies about caring for children with cancer at the end of life. Linear regression models identified associations between personal perspectives before, during, and after the family's cancer experience and outcomes (health behaviors, psychological distress, and social support). Fifty-eight siblings completed surveys (62% response rate). They were approximately 12 years bereaved, with a mean age of 26 years at the time of the survey (SD 7.8). Anxiety, depression, and illicit substance use increased during the year after their brother/sister's death but then returned to baseline. Siblings who reported dissatisfaction with communication, poor preparation for death, missed opportunities to say goodbye, and/or a perceived negative impact of the cancer experience on relationships tended to have higher distress and lower social support scores (P < 0.001-0.031). Almost all siblings reported that their loss still affected them; half stated that the experience impacted current educational and career goals. How siblings experience the death of a child with cancer may impact their long-term psychosocial well-being. Sibling-directed communication and concurrent supportive care during the cancer experience and the year after the sibling death may mitigate poor long-term outcomes.

Are elder siblings helpers or competitors? Antagonistic fitness effects of sibling interactions in humans

PubMed Central

Nitsch, Aïda; Faurie, Charlotte; Lummaa, Virpi

2013-01-01

Determining the fitness consequences of sibling interactions is pivotal for understanding the evolution of family living, but studies investigating them across lifetime are lacking. We used a large demographic dataset on preindustrial humans from Finland to study the effect of elder siblings on key life-history traits. The presence of elder siblings improved the chances of younger siblings surviving to sexual maturity, suggesting that despite a competition for parental resources, they may help rearing their younger siblings. After reaching sexual maturity however, same-sex elder siblings' presence was associated with reduced reproductive success in the focal individual, indicating the existence of competition among same-sex siblings. Overall, lifetime fitness was reduced by same-sex elder siblings' presence and increased by opposite-sex elder siblings' presence. Our study shows opposite effects of sibling interactions depending on the life-history stage, and highlights the need for using long-term fitness measures to understand the selection pressures acting on sibling interactions.

Psychoeducation for siblings of people with severe mental illness.

Sin, Jacqueline; Jordan, Cheryl D; Barley, Elizabeth A; Henderson, Claire; Norman, Ian

2015-05-08

Many people with severe mental illness (SMI) have siblings. Siblings are often both natural agents to promote service users' recovery and vulnerable to mental ill health due to the negative impact of psychosis within the family. Despite a wealth of research evidence supporting the effectiveness of psychoeducation for service users with SMI and their family members, in reducing relapse and promoting compliance with treatment, siblings remain relatively invisible in clinical service settings as well as in research studies. If psychoeducational interventions target siblings and improve siblings' knowledge, coping with caring and overall wellbeing, they could potentially provide a cost-effective option for supporting siblings with resulting benefits for service users' outcomes. To assess the effectiveness of psychoeducation compared with usual care or any other intervention in promoting wellbeing and reducing distress of siblings of people affected by SMI.The secondary objective was, if possible, to determine which type of psychoeducation is most effective. We searched the Cochrane Schizophrenia Group Trials Register and screened the reference lists of relevant reports and reviews (12th November 2013). We contacted trial authors for unpublished and specific data on siblings' outcomes. All relevant randomised controlled trials focusing on psychoeducational interventions targeting siblings of all ages (on their own or amongst other family members including service users) of individuals with SMI, using any means and formats of delivery, i.e. individual (family), groups, computer-based. Two review authors independently screened the abstracts and extracted data and two other authors independently checked the screening and extraction process. We contacted authors of trials to ascertain siblings' participation in the trials and seek sibling-specific data in those studies where siblings' data were grouped together with other participants' (most commonly other family members

Children exposed to intimate partner violence: influences of parenting, family distress, and siblings.

2015-02-01

The aim of this study was to investigate associations between maternal stress, parenting behavior, and sibling adjustment in relation to child trauma symptoms in families with and without a history of intimate partner violence (IPV). Maternal report was used to measure maternal stress and child trauma symptoms, whereas parenting behavior was assessed through an observational measure. Participants consisted of mothers with 2 school-age siblings recruited from the community. Results indicated that violent families reported higher levels of maternal stress and sibling trauma symptoms than nonviolent families, although no differences were found in parenting behavior. Sibling trauma symptoms and negative maternal behavior toward a sibling were strong predictors of trauma symptoms in younger siblings exposed to IPV but only modest predictors for older siblings. Moderator analyses showed that in IPV-affected families, the trauma symptoms of older siblings were related to the trauma symptoms of younger siblings when maternal stress was high.

Objective Although the symptoms of autism exhibit quantitative distributions in nature, estimates of recurrence risk in families have never previously considered or incorporated quantitative characterization of the autistic phenotype among siblings. Method We report the results of quantitative characterization of 2,920 children from 1,235 families participating in a national volunteer register who met the criteria of having at least one child clinically-affected by an autism spectrum disorder (ASD) and at least one full biological sibling. Results The occurrence of a traditionally-defined ASD in an additional child occurred in 10.9% of the families. An additional 20% of non-ASD-affected siblings had a history of language delay, half of whom had exhibited autistic qualities of speech. Quantitative characterization using the Social Responsiveness Scale (SRS) supported previously-reported aggregation of a wide range of subclinical (quantitative) autistic traits among otherwise unaffected children in multiple-incidence families, and a relative absence of quantitative autistic traits among siblings in single-incidence autism families. Girls whose standardized severity ratings fell above a first percentile severity threshold (relative to the general population distribution) were significantly less likely to have elicited community diagnoses than their male counterparts. Conclusions These data suggest that, depending on how it is defined, sibling recurrence in ASD may exceed previously-published estimates, and varies as a function of family type. The results support differences in mechanisms of genetic transmission between simplex and multiplex autism, and advance current understanding of the genetic epidemiology of autism. PMID:20889652

Training parents to mediate sibling disputes affects children's negotiation and conflict understanding.

PubMed

Smith, Julie; Ross, Hildy

2007-01-01

The effects of training parents to use formal mediation procedures in sibling disputes were examined in 48 families with 5- to 10-years-old children, randomly assigned to mediation and control conditions. Children whose parents were trained in mediation were compared with those whose parents intervened normally. Parents reported that children used more constructive conflict resolution strategies, compromised more often, and controlled the outcomes of conflicts more often in mediation families than in control families. Observations indicated less negativity in children's independent negotiations of recurrent conflicts, better understanding of the role of interpretation in assessing blame, and better knowledge of their siblings' perspectives in the mediation group. Thus, both social and social-cognitive gains resulted from experience with constructive conflict resolution.

First-born siblings show better second language skills than later born siblings

2015-01-01

We examined the extent to which three sibling structure variables number of siblings, birth order, and presence of an older sibling at school age are linked to the second language skills of bilingual children. The research questions were tested using an ethnically heterogeneous sample of 1209 bilingual children with German as a second language. Controlling for children’s age, sex, nationality, number of children’s books at home, family language and parental German language skills, hierarchical regression analyses showed an inverse relationship between the number of siblings and second language skills: the more siblings a child had, the lower was his/her second language proficiency. This relationship was mediated by attendance in early education institutions. Moreover, first-born siblings showed better second language skills than later born siblings. The current study revealed that the resource dilution model, i.e., the decrease in resources for every additional sibling, holds for second language acquisition. Moreover, the results indicate that bilingual children from families with several children benefit from access to early education institutions. PMID:26089806

Sibling relationships in adults who have siblings with or without intellectual disabilities.

Doody, Mairéad A; Hastings, Richard P; O'Neill, Sarah; Grey, Ian M

2010-01-01

There is relatively little research on the relationships between adults with intellectual disability and their siblings, despite the potential importance of these relationships for either individual's psychological well-being and future care roles that might be adopted by adult siblings. In the present study, sibling relationships of adults with adult siblings with (N=63) and without (N=123) intellectual disability were explored. Contact, warmth, conflict, and rivalry were measured using questionnaires available as an on-line survey. Expressed emotion was measured using the Five Minute Speech Sample over the telephone to establish an independently coded measure of criticism from the participant towards their sibling. Overall, there were few group differences in contact and sibling relationship. There was less telephone contact in the intellectual disability group, and less reported warmth in the relationship with siblings with intellectual disability although this was mainly associated with severe/profound intellectual disability. Exploratory analyses were conducted of the correlates of sibling relationships in both the intellectual disability and control groups. These analyses revealed a small number of different associations especially for conflict, which was lower when either the participant or sibling was younger in the control group but associated with relative age in the intellectual disability group.

Cognitive abilities in siblings of children with autism spectrum disorders.

2014-07-01

The aim of the present study was to assess the cognitive profiles of children with autistic spectrum disorder and of their healthy siblings (Siblings). With the term cognitive profile, we indicate the relationship extant among the values of verbal and performance subtests of the Wechsler Intelligence Scale. The conducted statistical analyses indicated that, although siblings showed a normal intelligent quotient and did not differ in this aspect from typically developing group, their cognitive profile was amazingly similar to that of their relatives affected by autism. A k-means clustering analysis on the values of single subtests further confirmed this result, showing a clear separation between typically developing children on the one side, and autistics and their siblings on the other. We suggest that the common cognitive profile observed in autistic children and their siblings could represent a marker of liability to autism and, thus, a possible intermediate phenotype of this syndrome.

Attachment states of mind and the quality of young adults' sibling relationships.

2011-09-01

This report examines young adults' states of mind regarding their early attachment experiences in relation to the observed and perceived quality of their sibling relationships. Sixty sibling pairs (18-25 years of age) were (a) administered the Adult Attachment Interview (George, Kaplan, & Main, 1985), (b) videotaped during a conflict resolution task, and (c) asked to describe the quality of their relationship using the Adult Sibling Relationship Questionnaire (Stocker, Lanthier, & Furman, 1997). As hypothesized, dismissing states of mind were associated with lower levels of positive and negative affect while participants attempted to resolve an area of conflict with a sibling as well as with relatively low levels of reported warmth in the relationship. In contrast-but also in line with predictions-preoccupied states of mind were associated with heightened expression of negative affect toward a brother or sister, and the siblings of highly preoccupied individuals reported more conflict in their relationships. Findings provide further support for the importance of young adults' representations of childhood attachment experiences with respect to the quality of their adult relationships. In addition, this study extends previous findings regarding the significance of dismissing versus preoccupied states of mind by demonstrating that these dimensions are differentially associated with behavioral and self-reported aspects of sibling relationship quality in early adulthood.

2015-01-01

Sibling relationships have been described as love-hate relationships by virtue of their emotional intensity, but we know little about how sibling positivity and negativity operate together to affect youth adjustment. Accordingly, this study charted the course of sibling positivity and negativity from age 10 to 18 in African American sibling dyads and tested whether changes in relationship qualities were linked to changes in adolescents’ internalizing and externalizing behaviors. Participants were consecutively-born siblings (at Time 1, older siblings averaged 14.03 (SD = 1.80) years of age, 48% female; younger siblings averaged 10.39 (SD = 1.07) years of age, 52% female) and two parents from 189 African American families. Data were collected via annual home interviews for three years. A series of multi-level models revealed that sibling positivity and sibling negativity declined across adolescence, with no significant differences by sibling dyad gender constellation. Controlling for age-related changes as well as time-varying parent-adolescent relationship qualities, changes in sibling negativity, but not positivity, were positively related to changes in adolescents’ depressive symptoms and risky behaviors. Like parent-adolescent relationships, sibling relationships displayed some distancing across adolescence. Nevertheless, sibling negativity remained a uniquely important relational experience for African American adolescents’ adjustment. PMID:25893573

Is sibling rivalry fatal?: siblings and mortality clustering.

PubMed

Kippen, Rebecca; Walters, Sarah

2012-01-01

Evidence drawn from nineteenth-century Belgian population registers shows that the presence of similarly aged siblings competing for resources within a household increases the probability of death for children younger than five, even when controlling for the preceding birth interval and multiple births. Furthermore, in this period of Belgian history, such mortality tended to cluster in certain families. The findings suggest the importance of segmenting the mortality of siblings younger than five by age group, of considering the presence of siblings as a time-varying covariate, and of factoring mortality clustering into analyses.

Siblings of children with a chronic illness: a meta-analysis.

2002-12-01

To review the literature pertaining to the siblings of children with a chronic illness. Fifty-one published studies and 103 effect sizes were identified and examined through meta-analysis. We found (1) a modest, negative effect size statistic existed for siblings of children with a chronic illness relative to comparison participants or normative data; (2) heterogeneity existed for those effect sizes; (3) parent reports were more negative than child self-reports; (4) psychological functioning (i.e., depression, anxiety), peer activities, and cognitive development scores were lower for siblings of children with a chronic illness compared to controls; and (5) a cluster of chronic illnesses with daily treatment regimes was associated with negative effect statistics compared to chronic illnesses that did not affect daily functioning. More methodologically sound studies investigating the psychological functioning of siblings of children with a chronic illness are needed. Clinicians need to know that siblings of children with a chronic illness are at risk for negative psychological effects. Intervention programs for the siblings and families of children with a chronic illness should be developed.

Being the victim of peer bullying is associated with increased risk of psychopathology, yet it is not known whether similar experiences of bullying increase risk of psychiatric disorder when the perpetrator is a sibling. We tested whether being bullied by a sibling is prospectively associated with depression, anxiety, and self-harm in early adulthood. We conducted a longitudinal study using data from >6900 participants of a UK community-based birth cohort (Avon Longitudinal Study of Parents and Children) who reported on sibling bullying at 12 years. Our main outcome measures were depression, anxiety, and self-harm, assessed using the Clinical Interview Schedule-Revised during clinic assessments when participants were 18. Children who were frequently bullied were approximately twice as likely to have depression (odds ratio [OR] = 2.16; 95% confidence interval [CI], 1.33-3.51; P < .001), self-harm (OR = 2.56; 95% CI, 1.63-4.02; P < .001), and anxiety (OR = 1.83; 95% CI, 1.19-2.81; P < .001) as children who were not bullied by siblings. The ORs were only slightly attenuated after adjustment for a range of confounding individual, family, and peer factors. The population-attributable fractions suggested that 13.0% (95% CI, 1.0%-24.7%) of depression and 19.3% (95% CI, 7.6%-29.6%) of self-harm could be explained by being the victim of sibling bullying if these were causal relationships. Being bullied by a sibling is a potential risk factor for depression and self-harm in early adulthood. Our results suggest that interventions designed to target sibling bullying should be devised and evaluated. Copyright © 2014 by the American Academy of Pediatrics.

Ripple effects of developmental disabilities and mental illness on nondisabled adult siblings

Developmental disabilities and severe mental illness are costly to the affected individual and frequently to their family as well. Little studied are their nondisabled siblings. Here we examine major life course outcomes (education, employment, and marriage) of these siblings in adulthood using data from the Wisconsin Longitudinal Study. Our sample comprises 113 individuals with developmental disabilities and 337 of their nondisabled siblings; 97 individuals with mental illness and 235 of their nondisabled siblings; and 17,126 unaffected comparison group members. We find that siblings of individuals with mental illness have less education and less employment than the unaffected comparison group, whereas those who have a sibling with developmental disabilities had normative patterns of education and employment, but less marriage and more divorce. Robustness tests incorporating genetic data do not change the conclusions based on the nongenetic analyses. PMID:24607704

Duchenne muscular dystrophy (DMD) is a progressive, impairing, life-limiting disorder of childhood. Little is known about how siblings adapt to this. The aim of this study is to document psychosocial adjustment in siblings of patients with DMD. Healthy siblings (11-18 years old) of young people with DMD attending a specialist paediatric centre and their parent/main carer took part. Parents, siblings and teachers completed a battery of questionnaires: (i) to assess psychiatric risk the Strengths and Difficulties Questionnaire (SDQ), General Health Questionnaire (GHQ), Hospital Anxiety and Depression Scale (HADS); (ii) to measure general wellbeing: SF-36; (iii) to document DMD illness disability: Functional Disability Inventory (FDI); (iv) to assess family function and life stresses for the unaffected sibling: Family Assessment Device (FAD), Family Burden Interview Schedule and Life Events Checklist. Forty six/77 eligible siblings (24 females/22 males); (mean age 14 years (SD 2.3)) took part. Although their mean psychological functioning and wellbeing questionnaire scores were comparable to normative data, there was a trend for more siblings scoring at high-risk for psychological (mainly emotional) problems. Weak/moderate associations with psychological symptoms in siblings varied according to informant and included the following factors: closeness in age to the affected sibling; older sibling age; extent of wheelchair use, burden of illness on family interactions, and siblings reporting high impact of illness on their lives. Psychological symptoms were also associated with less sibling involvement in patient care, with broader psychosocial and family disadvantage and with life stresses. Siblings have an increased risk for emotional problems, which appears influenced by specific illness factors. Copyright (c) 2009 European Paediatric Neurology Society. Published by Elsevier Ltd.

A Sibling Death in the Family: Common and Consequential

PubMed Central

Fletcher, Jason; Mailick, Marsha; Song, Jieun

2015-01-01

Although a large literature analyzes the determinants of child mortality and suggests policy and medical interventions aimed at its reduction, there is little existing analysis illuminating the consequences of child mortality for other family members. In particular, there is little evidence exploring the consequences of experiencing the death of a sibling on one’s own development and transition to adulthood. This article examines the prevalence and consequences of experiencing a sibling death during one’s childhood using two U.S. data sets. We show that even in a rich developed country, these experiences are quite common, affecting between 5 % and 8 % of the children with one or more siblings in our two data sets. We then show that these experiences are associated with important reductions in years of schooling as well as a broad range of adult socioeconomic outcomes. Our findings also suggest that sisters are far more affected than brothers and that the cause of death is an important factor in sibling effects. Overall, our findings point to important previously unexamined consequences of child mortality, adding to the societal costs associated with childhood mortality as well as suggesting additional benefits from policy and medical innovations aimed at curbing both such deaths and subsequent effects on family members.

Adult sibling experience, roles, relationships and future concerns - a review of the literature in learning disabilities.

PubMed

Davys, Deborah; Mitchell, Duncan; Haigh, Carol

2011-10-01

This paper provides a review of the literature related to adult siblings of learning-disabled people. Siblings of learning-disabled people are often looked upon as next of kin when older parents die; however, there is little research regarding sibling views and wishes. A literature review of published peer-reviewed empirical research was undertaken. Electronic databases and citation tracking were used to collate data using key terms such as adult siblings and learning disability. Relevant articles were analysed, compared and contrasted. Six key themes emerged suggesting a varied impact of learning disability upon sibling lives in areas that include life choices, relationships, identity and future plans. Some siblings report a positive impact upon life, others state their lives are comparable with other adults who do not have a learning-disabled sibling and others still report a negative impact. Sibling roles and relationships are varied. Evidence suggests that sibling roles, relationships and experience are affected by life stage. Parents often have a primary care role for the disabled person, whilst siblings perform a more distant role; however, sibling involvement often rises when parents are no longer able to provide previous levels of support. Many factors appear to affect the sibling experience and uptake of roles including gender, life stage and circumstances, level of disability, health status and relationships between family members. Siblings are concerned about the future, particularly when parents are no longer able to provide support, and many appear to have expectations of future responsibilities regarding their disabled sibling. As siblings of people who have a learning disability are often expected by society to provide support, it is important that health and social care practitioners are aware of issues that may impact on this relationship. © 2011 Blackwell Publishing Ltd.

This study examined parents' differential treatment (PDT) of siblings, discrepancies between parent and youth reports of PDT, and their links with relationships between adolescents and their mothers and fathers across three years. Participants were first- (Time 1 M age = 15.71, SD = 1.07) and secondborn (Time 1 M age = 13.18, SD = 1.29) siblings from 381, predominately white, working and middle class families. Analyses revealed that siblings' perceptions of being favored predicted less conflict with and greater warmth from both mothers and fathers, primarily for secondborn adolescents. Larger discrepancies between maternal and youth reports of differential affection were linked to more maternal conflict and less warmth for firstborns. These findings may suggest a hierarchy within families: parents may serve as referents for firstborns and firstborns as referents for secondborns.

Childhood attention-deficit/hyperactivity disorder (ADHD) has been associated with reduced health and well-being of patients and their families. The authors undertook a large UK survey-based observational study of the burden associated with childhood ADHD. The impact of ADHD on both the patient (N = 476) and their siblings (N = 337) on health-related quality of life (HRQoL) and happiness was quantified using multiple standard measures [e.g. child health utility-9D (CHU-9D), EuroQol-5D-Youth]. In the analysis, careful statistical adjustments were made to ensure a like-for-like comparison of ADHD families with two different control groups. We controlled for carers' ADHD symptoms, their employment and relationship status and siblings' ADHD symptoms. ADHD was associated with a significant deficit in the patient's HRQoL (with a CHU-9D score of around 6 % lower). Children with ADHD also have less sleep and were less happy with their family and their lives overall. No consistent decrement to the HRQoL of the siblings was identified across the models, except that related to their own conduct problems. The siblings do, however, report lower happiness with life overall and with their family, even when controlling for the siblings own ADHD symptoms. We also find evidence of elevated bullying between siblings in families with a child with ADHD. Overall, the current results suggest that the reduction in quality of life caused by ADHD is experienced both by the child with ADHD and their siblings.

Sibling dilution hypothesis: a regression surface analysis.

This study examined relationships between sibship size (the number of children in a family), birth order, and measures of academic performance, academic self-concept, and educational aspirations at different levels of family educational resources. As part of a national longitudinal study of Australian secondary school students data were collected from 2,530 boys and 2,450 girls in Years 9 and 10. Regression surfaces were constructed from models that included terms to account for linear, interaction, and curvilinear associations among the variables. Analysis suggests the general propositions (a) family educational resources have significant associations with children's school-related outcomes at different levels of sibling variables, the relationships for girls being curvilinear, and (b) sibling variables continue to have small significant associations with affective and cognitive outcomes, after taking into account variations in family educational resources. That is, the investigation provides only partial support for the sibling dilution hypothesis.

Sibling unity during family transitions is considered a protective factor for child behavior problems, but there is little empirical support for the widespread child protection policy of placing siblings together in foster care. In a prospective study of 156 maltreated children, siblings were classified in 1 of 3 placement groups: continuously together (n = 110), continuously apart (n = 22), and disrupted placement (siblings placed together were separated; n = 24). Changes in child adjustment as a function of sibling relationship and placement group were examined. Sibling positivity predicted lower child problems at follow-up (about 14 months later), while sibling negativity predicted higher child problems. Placement group did not affect child behavior problems at follow-up; however, compared to siblings in continuous placement (either together or apart), siblings in disrupted placement with high initial behavior problems were rated as having fewer problems at follow-up, while siblings in disrupted placement with low initial behavior problems were rated as having more problems at follow-up. These findings highlight the importance of considering relationships between siblings and the risk that one poses to another before early placement decisions are made.

Sibling solidarity in a polygamous community in the USA. unpacking inclusive fitness.

This pilot study explores the degree of solidarity felt between full and half siblings who are raised in a Mormon Fundamentalist polygamous community. The community under study is unique in that, at the level of official culture, it actively promotes full and half sibling solidarity through an ethos that strives to downplay genetic differences in favor of a harmonious family living together in one household. This community is an ideal cultural setting in which to examine the suitability of inclusive fitness theory for understanding the factors that promote family cohesion, sibling solidarity, and rivalry. Our main question becomes: is the degree of sibling solidarity a manifestation of genetic closeness or a natural byproduct of emotional closeness that arises from being raised together? We found evidence for more solidarity between full siblings than between half siblings. Our data suggest that, despite the force of religious ideals, and notwithstanding the continued close physical proximity of half siblings in the polygamous family, there is a pronounced clustering of feeling and affection in the polygamous family that is consistent with inclusive fitness theory.

Siblings may act as caregivers and role models during mealtimes, and develop caregiving skills by observing and imitating the behavior of their mothers. The objective of this study was to examine the association between maternal feeding behaviors and encouragements to eat delivered from the sibling to the index child during mealtimes. Index children aged 4-8 years (n = 69) were videotaped while eating a routine evening meal at home with one sibling present. Encouragements to eat delivered from the sibling to the index child were coded from the videotapes. Mothers completed the Child Feeding Questionnaire and the Caregiver's Feeding Styles Questionnaire. Poisson regression was used to examine the association of maternal Pressure to Eat, Restriction, Monitoring, Verbal Direction, and Coercion with number of encouragements to eat delivered from the sibling to the index child. Models were adjusted for index child's age, sex, and race/ethnicity, and maternal education. Results showed that maternal Pressure to Eat (Rate Ratio (RR): 1.39, 95% confidence interval (CI): 1.19, 1.69), Restriction (RR: 1.31, 95% CI: 1.07, 1.60), Verbal Direction (RR: 2.04, 95% CI: 1.68, 2.47), and Coercion (RR: 1.58, 95% CI: 1.29, 1.92) were each positively associated with the number of encouragements to eat delivered from the sibling to the index child. Maternal Monitoring was not associated with the number of encouragements to eat delivered from the sibling to the index child (RR: 0.92, 97% CI: 0.78, 1.09). Findings suggest that maternal behavior during mealtimes may affect the index child indirectly by shaping the behavior of siblings. Since controlling feeding behaviors have been associated with greater child obesity risk, future studies may evaluate the compounded effect of experiencing controlling feeding behaviors from both mothers and siblings.

Roche, Rosa M; Brooten, Dorothy; Youngblut, JoAnne M

Understanding children's health after a sibling's death and what factors may affect it is important for treatment and clinical care. This study compared children's and their parents' perceptions of children's health and identified relationships of children's age, gender, race/ethnicity, anxiety, and depression and sibling's cause of death to these perceptions at 2 and 4 months after sibling death. 64 children and 48 parents rated the child's health "now" and "now vs before" the sibling's death in an ICU or ER or at home shortly after withdrawal of life-prolonging technology. Children completed the Child Depression Inventory and Spence Children's Anxiety Scale. Sibling cause of death was collected from hospital records. At 2 and 4 months, 45% to 54% of mothers' and 53% to 84% of fathers' ratings of their child's health "now" were higher than their children's ratings. Child health ratings were lower for: children with greater depression; fathers whose children reported greater anxiety; mothers whose child died of a chronic condition. Children's ratings of their health "now vs before" their sibling's death did not differ significantly from mothers' or fathers' ratings at 2 or 4 months. Black fathers were more likely to rate the child's health better "now vs before" the death; there were no significant differences by child gender and cause of death in child's health "now vs before" the death. Children's responses to a sibling's death may not be visually apparent or become known by asking parents. Parents often perceive their children as healthier than children perceive themselves at 2 and 4 months after sibling death, so talking with children separately is important. Children's perceptions of their health may be influenced by depression, fathers' perceptions by children's anxiety, and mother's perceptions by the cause of sibling death.

Reasons for chronic liver and kidney failure may vary; sometimes more than 1 family member may be affected, and may require a transplant. The aim of this study was to examine the similarities or differences between the perioperative characteristics of siblings undergoing liver or kidney transplant. The medical records of 6 pairs of siblings who underwent liver transplant and 4 pairs of siblings who underwent kidney transplant at Baskent University Hospital between 1989 and 2014 were retrospectively analyzed. Collected data included demographic features; comorbidities; reasons for liver and kidney failure; perioperative laboratory values; intraoperative hemodynamic parameters; use and volume of crystalloids, colloids, blood products, cell saver system, and albumin; duration of anesthesia; urine output; and postoperative follow-up data. The mean age of the 6 sibling pairs who underwent liver transplant was 16.3 ± 12.2 years. All 12 patients had Child-Pugh grade B cirrhosis, with mean disease duration of 7.8 ± 3.9 years. There were no significant differences between siblings with respect to intraoperative blood product transfusion, crystalloid and colloid fluid replacements, hypotension frequency, blood gas analyses, urinary output, duration of anhepatic phase, inotropic agent administration, postoperative laboratory values, need for mechanical ventilation and vasopressors, occurrence of acute renal failure and infections, and duration intensive care unit stay (P > .05). The mean age of the 4 sibling pairs who underwent kidney transplant was 21.3 ± 6.4 years, with mean duration of renal insufficiency of 2.2 ± 1.6 years. There were no significant differences between siblings with respect to intraoperative crystalloid and colloid fluid administration, duration of anesthesia, intraoperative mannitol and furosemide administration, and postoperative laboratory values (P > .05). In conclusion, the 6 sibling pairs who underwent liver transplant and 4 sibling pairs who

Among typically developing children, having sibling relationships promotes the development of social skills. This is a retrospective study of the effect of having sibling/s on the severity of the clinical presentation of autism spectrum disorder (ASD). The study included 112 children, 99 males and 15 females, mean age 29.6 ± 9.2 months, diagnosed with ASD. The study population was composed of a group of children with ASD who had older typically developing sibling/s (n = 56) pair-matched for age and cognitive level to a group of children with ASD without sibling/s. Each participant underwent a comprehensive assessment using standardized tests. The group with older sibling/s had less severe observed social deficits (Autism Diagnostic Observation Schedule-Social Affect calibrated severity scales [ADOS-SA-CSS]) and fewer reported non-verbal communication impairments (Autism Diagnostic Interview-Revised [ADI-R]). Regression analyses revealed that, for the ADOS-SA-CSS, higher cognitive level and having older sibling/s were associated with less severe observed social affect deficits. This model explained 32.0 % of the variance. For the ADI-R communication scores, older age, higher cognitive level and having older sibling/s were associated with less severe reported non-verbal communication impairments. This model explained 33.0 % of the variance. The main finding in this study is that a familial factor, specifically having older sibling/s, was associated with better social communication abilities in children with ASD, in addition to age and cognitive ability. Having sibling/s may offer opportunities for the child with ASD to experience social interactions with children and to acquire communication skills.

2008-01-01

The present study contrasted the later life sibling relationships, patterns of family formation, and psychological distress and well-being of siblings of adults with disabilities to a non-disabled normative group. We identified 268 siblings of adults with mild intellectual deficits and 83 siblings of adults with mental illness from the Wisconsin Longitudinal Study, a prospective longitudinal study that followed participants from age 18 to age 64. Compared to the norm (n = 791), siblings of adults with mild intellectual deficits had more contact with family members and were more likely to live in the same state as the sibling with the disability, but reported less affective closeness. Siblings of adults with mental illness reported more psychological distress, less psychological well-being and less adaptive personality characteristics compared to the norm, particularly for siblings of men with mental illness. There were no differences between groups in the patterns of marriage and childbearing. PMID:19102611

Ninety-six multiplex type I diabetic families were typed at the 5' flanking region of the insulin gene by using a PCR assay that better resolves the VNTR into multiple alleles. Affected sibling pairs shared 2, 1, and 0 VNTR alleles - identical by descent - at a frequency of .47, .45, and .08, respectively, a ratio that deviated from the expected 1:2:1 ratio (P<.001). These results confirm linkage of the chromosome 11p15.5 region with type I diabetes mellitus susceptibility. 20 refs., 2 tabs.

Being bullied by a sibling has been recently identified as a potential risk factor for developing depression and self-harm. It is unknown whether this risk extends to other serious mental health problems such as psychosis. We investigated whether sibling bullying victimization or perpetration in middle childhood was prospectively associated with psychotic disorder in early adulthood. The current study investigated 6988 participants of the Avon Longitudinal Study of Parents and Children, a UK community-based birth cohort. Sibling bullying was reported at 12 years and psychotic disorder was assessed via a semi-structured interview at 18 years. Involvement in sibling bullying was associated with psychotic disorder in a dose-response fashion, even after controlling for a range of confounders. Those involved several times a week were 2-3 times more likely to meet criteria for a psychotic disorder [odds ratio (OR); 95% confidence interval (CI)]: victimization (OR 2.74; CI 1.28-5.87); perpetration (OR 3.16; CI 1.35-7.41). Categorical analysis indicated that particularly victims (OR 3.10; CI 1.48-6.50) and bully-victims (OR 2.66; CI 1.24-5.69) were at increased risk of psychotic disorder. Involvement in both sibling and peer bullying had a dose-effect relationship with a psychotic disorder, with those victimized in both contexts having more than four times the odds for a psychotic disorder (OR 4.57; CI 1.73-12.07). Parents and health professionals should be aware of the adverse long-term effects of sibling bullying.

Usability of online psychoeducation for siblings of people with psychosis.

The E Sibling Project aims to address the needs of siblings of individuals affected by psychosis through provision of a comprehensive online intervention. The online intervention comprises four core elements, including: information on psychosis; various coping and promoting well-being strategies; siblings' blogs and discussion forum with peers; and an "Ask the Experts" function. After the intervention-prototype was developed, we tested its feasibility, usability and acceptability by siblings. We evaluated the usability of the intervention-prototype using a non-randomised usability study with siblings of individuals diagnosed with psychosis. The usability study adapted Poulson et al's framework to collect subjective feedback from participants on ease of use, perceived usefulness and acceptability, together with objective usage data on the intervention. Twenty siblings were recruited to the usability test; 19 tried out the resource-prototype over a 4-week period and 17 completed the online evaluation after using the intervention. In total, 906 page-views were made by the participants and each spent about two hours using the resource. Participants evaluated the intervention as helpful, relevant and useful in terms of content, design and usability. Developments are needed to improve the navigation and intuitiveness of the resource. Using an internet-based information-giving and peer support intervention to promote wellbeing and coping is feasible and acceptable to siblings of people with psychosis.

Theoretical Perspectives on Sibling Relationships

2011-01-01

Although siblings are a fixture of family life, research on sibling relationships lags behind that on other family relationships. To stimulate interest in sibling research and to serve as a guide for future investigations by family scholars, we review four theoretical psychologically oriented perspectives—(a) psychoanalytic-evolutionary, (b) social psychological, (c) social learning, and (d) family-ecological systems—that can inform research on sibling relationships, including perspectives on the nature and influences on developmental, individual, and group differences in sibling relationships. Given that most research on siblings has focused on childhood and adolescence, our review highlights these developmental periods, but we also incorporate the limited research on adult sibling relationships, including in formulating suggestions for future research on this fundamental family relationship.

2011-04-01

This study used nationwide hospital records to examine sibling risk of any type of anxiety disorder in Sweden over a 40-year period. This study, carried out between 1 January 1968 and 31 December 2007, of the entire population of Sweden, linked information on family relationships from the nationwide Multi-Generation Register with information from the nationwide Swedish Hospital Discharge Register on first diagnosis of anxiety disorder. A total of 42,602 persons hospitalized for anxiety disorders and 2093 affected siblings were identified. Standardized incidence ratios (SIR) were calculated by comparing risk in siblings of persons hospitalized for anxiety disorders with risk in persons whose siblings had no hospital diagnosis of anxiety disorders. The sibling risk was 2.26, which was independent of sex and age differences between siblings. The SIR was highest in siblings <20 years of age (2.83). Analysis of risk by subtype showed that having a sibling diagnosed with any anxiety disorder resulted in increased risks of a number of disorders; the highest increased risk was of social phobia (SIR 3.68, 95% confidence interval, 1.68-7.69). Risk of panic disorder, generalized anxiety disorder, mixed anxiety and depressive disorder, and obsessive-compulsive disorder was raised in female but not male siblings. Heritable effects likely play an important role in the cause of anxiety disorders, but the extent of their role remains to be established. Important contributions could be made by studies of gene-environment interactions that have sufficient sample sizes to produce reliable results. © 2011 The Authors.

2015-01-01

To illuminate processes that contribute to the development of sibling differences, this study examined cross lagged links between parents’ beliefs about sibling differences in academic ability and differences between siblings’ grade point averages (GPAs), and cross lagged links between differences in siblings’ GPAs and sibling differences in academic interests. Data were collected from mothers, fathers, firstborn (M age at Time 1 = 15.71, SD = 1.07) and secondborn (M age at Time 1 = 13.18, SD = 1.29) youth from 388 European American Families on three annual occasions. Findings revealed that, after controlling for siblings’ average grades and prior differences in performance, parents’ beliefs about sibling differences in academic ability predicted differences in performance such that youth rated by parents as relatively more competent than their sibling earned relatively higher grades the following year. Siblings’ relative school performance, however, did not predict parents’ beliefs about differences between siblings’ competencies. Further, after controlling for average interests and grades, sibling differences in GPA predicted differences in siblings’ interests such that youth who had better grades than their siblings reported relatively stronger academic interests the following year. Differences in interest, however, did not predict sibling differences in GPA. Findings are discussed in terms the role of sibling dynamics in family socialization. PMID:26053351

Child passenger injury risk in sibling versus non-sibling teen driver crashes: a US study.

Several international jurisdictions allow family exemptions to graduated driver licensing passenger restrictions. The objective of this research was to examine differences in injury risk to US child passengers in crashes involving sibling versus non-sibling teen drivers, and to compare outcomes with crashes involving adult drivers. Insurance claim and telephone survey data were collected on 16 233 child passengers (representing 289 329 children) in 17 US jurisdictions. There was a trend toward higher restraint non-use by child passengers in the non-sibling group than in the sibling group (9.6% vs 4.7%; p = 0.08). Children in the sibling group had a 40% lower risk of injury than those in the non-sibling group (adjusted OR 0.60, 95% CI 0.40 to 0.90); however, injury risk was higher in the sibling group than in children traveling with adults (adjusted OR 1.57, 95% CI 1.09 to 2.26). Child passengers riding with sibling teen drivers may be safer than those riding with non-sibling teens, but not as safe as those riding with adult drivers.

Sibling influence on mexican-origin adolescents' deviant and sexual risk behaviors: the role of sibling modeling.

2014-05-01

A growing body of research indicates that siblings uniquely influence each other's health risk behaviors during adolescence and young adulthood. Mechanisms underlying these associations, however, are largely unknown because they are rarely tested directly. The present study addressed this gap by examining the role of sibling modeling in explaining changes in Mexican-origin youths' deviant and sexual risk behaviors over time. The sample included 380 Mexican-origin siblings (older sibling age: M = 21.18, SD = 1.59; younger sibling age: M = 18.19, SD = .46) from (N = 190) families. Participants provided self-reports of their sibling relationship qualities, including modeling, as well as their engagement in deviant and sexual risk-taking behaviors in two home interviews across a 2-year span. A series of residualized regression models revealed that younger siblings' perceptions of modeling moderated the links between older siblings' deviant and sexual risk behaviors and younger siblings' subsequent behaviors in those same domains. Specifically, high levels of modeling predicted stronger associations between older siblings' earlier and younger siblings' later risk behaviors controlling for younger siblings' earlier behaviors as well as variables that have been used as proxies for social learning in previous research. Social learning mechanisms, especially modeling, are salient processes through which older siblings transmit norms and expectations regarding participation in health risk behaviors. Future research should continue to explore the ways in which siblings influence each other because such processes are emerging targets for intervention and prevention.

Sibling Facilitation Mediates the Association Between Older and Younger Sibling Alcohol Use in Late Adolescence

Samek, Diana R.; McGue, Matt; Keyes, Margaret; Iacono, William G.

2014-01-01

Previous research has shown adolescent siblings are similar in their alcohol use and that this similarity is largely due to their shared environment. Using a genetically-informed sibling sample (196 full-biological pairs, 384 genetically unrelated pairs), we confirmed that the extent to which older siblings facilitate younger siblings’ alcohol use (i.e., help them get alcohol) was one factor contributing to this shared environmental association. All analyses controlled for parent and peer influences. Findings were not moderated by sibling differences in genetic relatedness, gender, or ethnicity. Proximity in sibling age strengthened these associations, somewhat. Results were especially strong for sibling pairs where the older sibling was of legal drinking age. Implications for prevention and intervention are discussed. PMID:26640355

Sibling influences on prosocial behavior.

PubMed

Hughes, Claire; McHarg, Gabrielle; White, Naomi

2018-04-01

Sibling relationships are characterized by familiarity and emotional intensity. Alongside frequent shared play, sibling interactions feature complementary interactions (e.g. teaching, caregiving) reflecting age-related asymmetries in socio-cognitive skills. These aspects may underpin sibling influences on prosocial behavior: theoretical accounts of social influences on prosocial behavior highlight emotion sharing, goal alignment, the intrinsically rewarding nature of social interaction, and scaffolding of social norms. Taking a fine-grained approach to prosocial behavior, we examine these processes in relation to sibling influences on children's comforting, sharing, and helping. Emergent themes include: developmental change in the nature of sibling influences on prosocial behavior, the need to consider sibling influences in the wider family context, and the importance of individual differences in the quality of sibling relationships.

The policy statement of the American academy of pediatrics – children as hematopoietic stem cell donors – a proposal of modifications for application in the UK

PubMed Central

2013-01-01

Background With a view to addressing the moral concerns about the use of donor siblings, the Policy Statement of the American Academy of Pediatrics - Children as Hematopoietic Stem Cell Donors (the Policy) has laid out the criteria upon which tissue harvest from a minor would be permissible. Discussion Although tissue harvest serves the best interests of recipient siblings, parents are also obliged to act in the best interests of the donor sibling in the UK. Tissue harvest should proceed if and only if it serves the best interests of both the donor and recipient. Parents should be forbidden, and they are by UK law, to consent to tissue harvest unless there are substantial benefits for an incompetent minor that can outweigh the potential harm. There is no basis to subject a minor to the medical risks of tissue harvest if the recipient sibling can wait without significant risks of complications until the donor becomes Gillick competent. We also argue that the Policy fails to take into account recent advances in haematopoietic transplantation from haploidentical donors or related tissue-matched donors. Summary Unless a recipient sibling will suffer from serious complications or die without the transplantation and no other medically equivalent donors are available, there is no moral or legal basis to violate the donor sibling’s right to bodily integrity. Accordingly, we propose that the Policy should be modified in order to fully satisfy the legal requirements for application in the UK and other commonwealth jurisdictions with similar statute laws protecting minors.

To examine psychological functioning, post-traumatic growth (PTG), coping, and cancer-related characteristics of adolescent cancer survivors' parents and siblings.
. Descriptive, correlational.
. Children's Hospital of Western Ontario in London, Ontario, Canada.
. Adolescents who finished cancer treatment 2-10 years prior (n = 31), as well as their parents (n = 30) and siblings (n = 18). 
. Participants completed self-report measures of psychological distress, PTG, life satisfaction, coping, and cancer-related characteristics.
. Psychological functioning, PTG, and coping.
. Parents' and siblings' PTG levels were similar to survivors' PTG levels; however, parents reported higher PTG than siblings. Parents who used less avoidant coping, were younger, and had higher life satisfaction experienced less psychological distress. Parents whose survivor children used more active coping reported less psychological distress. Siblings who were older used more active coping, and the longer it had been since their brother or sister was diagnosed, the less avoidant coping they used. 
. Childhood and adolescent cancer affects survivors' siblings and parents in unique ways.
. Relationship to the survivor, use of coping strategies, life satisfaction, and time since diagnosis affect family members' postcancer experiences.

Considerations of Elder Sibling Closeness in Predicting Younger Sibling Substance Use: Social Learning versus Social Bonding Explanations

2011-01-01

Adolescent siblings are often similar in a variety of adjustment outcomes, yet little is known about the processes that explain sibling influences during adolescence. Two alternative explanations were tested, attachment (based in social bonding theory) and anaclitic identification (based in social learning theory). Hypotheses were tested using a sample of 613 adolescent sibling pairs (206 non-adopted, 407 adopted; elder sibling Mage = 16.1, younger sibling Mage = 13.8) across three sibling contexts (gender composition, age difference, and genetic similarity). Attachment explanations were supported such that the greater the perceived sibling emotional and behavioral closeness, the lower the likelihood of substance use; however, there were considerable moderating effects of sibling gender composition. Anaclitic identification explanations were not supported; closeness and elder sibling substance use did not interact to predict younger sibling substance use. Overall, this research adds to a body of work demonstrating important sibling influences on adolescent substance use. PMID:21988080

Sibling influences on childhood development.

PubMed

Dunn, J

1988-03-01

To summarize the main points concerning sibling influence: 1. That siblings play a causal role in the development of aggressive behavior, in children's style of conflict behavior and in cooperative fantasy play is strongly suggested by recent research. 2. Marked problems in the sibling relationship are indicative of other problems, but a causal role for siblings is not established, other than for aggressive behavior. 3. Family factors are closely involved in the quality of sibling relationships--and thus in sibling influence, namely differential parental behavior, and the emotional climate of the family. That is, it is important not to consider the sibling relationship in isolation from other family relationships. 4. Studies of families under stress indicate heightened importance of these family factors. 5. It is likely, but not yet established, that later-born siblings are influenced by first-born in socio-cognitive development and gender identity. 6. Finally it should be noted that an important theme in current research on siblings is a concern with the question of why siblings develop to be so different from one another. It has been shown that the major source of environmental influence on the development of individual differences is within-family rather than between-family differences in experience (Plomin & Daniels, 1987). The different experiences each sibling may have within their relationship is one potential source of such differential environmental influence. Thus documenting the influence of siblings upon each other takes on added significance: By clarifying the extent and nature of this influence we will gain not only useful clinical information but illumination on a developmental principle of very general significance.

Sibling Supporters' Experiences of Giving Support to Siblings Who Have a Brother or a Sister With Cancer.

PubMed

Nolbris, Margaretha Jenholt; Nilsson, Stefan

Siblings of a child with a life-threatening disease, such as cancer, have a right to measures that promote their health and welfare. Siblings may find it hard to understand what is happening to the sick child with cancer and why he or she reacts as he or she does. The aim of the study was to explore sibling supporters' thoughts about the experiences they had in providing support for siblings with a brother or a sister with a life-threatening disease such as cancer. All the 12 sibling supporters currently working in Sweden participated in a qualitative, descriptive study from which 5 categories emerged, showing that the sibling supporters supported siblings from diagnosis until possible death. They enabled siblings who were in the same situation to meet each other and arranged activities suited to their ages, as well as offering an encouraging environment. To help the siblings, the sibling supporters found it necessary to interact with both the parents and the ward staff. The sibling supporters felt that their support was important and necessary in helping siblings promote their own health both when the sick child was alive and also after his or her death. The experience of the sibling supporters was that they listened to the siblings' stories and met them when they were in their crisis. The study confirms that sibling supporters should be a part of the health care team that treat and support the family when a child has cancer.

Older siblings as potential supervisors of younger siblings: sibling supervisors' recognition of injury-risk behaviours and beliefs about supervisee risk taking and potential injury outcomes.

PubMed

Morrongiello, B A; Schell, S L; Stewart, J

2015-07-01

Past research has shown that increased injury risk for supervisees during sibling supervision is in part due to the supervision practices of older siblings. The current study used a photo sorting task to examine older siblings' recognition of injury-risk behaviours, their perceived likelihood of supervisees engaging in, or being injured while engaging in, these behaviours, and awareness of past risk-taking behaviours of supervisees. Mothers completed the same measures and an interview about sibling supervision in the home. Mothers reported that sibling supervision occurred most frequently in the kitchen, living room, and children's bedrooms, for approximately 39 min/day, and that the more time the children spent together in a room, the more frequently the older sibling supervised the younger one. The most common reasons mothers gave for why sibling supervision was allowed included beliefs that the older child knows about hazards and unsafe behaviours and that the child could provide adequate supervision. Photo sort results revealed that older siblings were able to correctly identify about 98% of risk behaviours, with these scores significantly higher than what mothers expected (79%). However, compared with mothers, older siblings were less aware of risk behaviours that their younger siblings had engaged in previously. In addition, mothers rated supervisees as 'fairly likely' both to engage in risk behaviours and to experience an injury if they tried these behaviours, whereas sibling supervisors rated both supervisee risk behaviour and injury outcomes as 'not likely' to occur. Older siblings showed good knowledge of hazards but failed to realize that younger children often engage in injury-risk behaviours. Efforts to improve the supervision practices of sibling supervisors need to include changing their perception of supervisees' injury vulnerability and potential injury severity, rather than targeting to increase knowledge of injury-risk behaviours per se. �

Bullying in the family: sibling bullying.

PubMed

Wolke, Dieter; Tippett, Neil; Dantchev, Slava

2015-10-01

Sibling relationships have a substantial and lasting effect on children's development. Many siblings experience some occasional conflict, however, up to 40% are exposed to sibling bullying every week, a repeated and harmful form of intrafamilial aggression. We review evidence on the precursors, factors relating to peer bullying, and mental health consequences of sibling bullying. Parenting quality and behaviour are the intrafamilial factors most strongly associated with bullying between siblings. Sibling bullying increases the risk of being involved in peer bullying, and is independently associated with concurrent and early adult emotional problems, including distress, depression, and self-harm. The effects appear to be cumulative, with those children bullied by both siblings and peers having highly increased emotional problems compared with those bullied by siblings or peers only, probably because they have no safe place to escape from bullying. The link between sibling and peer bullying suggests interventions need to start at home. Health professionals should ask about sibling bullying and interventions are needed for families to prevent and reduce the health burden associated with sibling bullying.

Spondyloepiphseal dysplasia congenita in siblings born to unaffected parents: ? germ line mosaicism

Mulla, W.; McDonald-McGinn, D.; Zackai, E.

1994-09-01

Germ line mosaicism has been used to explain the birth of more than one child affected with a dominantly inherited disorder born to unaffected parents. Furthermore, it has been confirmed clinically in families where recurrence in siblings was originally thought to be autosomal recessive, but were affected individuals have reproduced affected offspring. Firm evidence of germ line mosaicism using mutation analysis by molecular methods exists for some autosomal disorders. We present two siblings with spondyloepipheseal dysplasia congenita (SEDC) born to unaffected parents. This suggests the presence of germ line mosaicism in this entity. Patient 1 was born at 32 weeksmore » gestation to a G1P1 Puerto Rican mother. The pregnancy was complicated by polyhydramnios. The neonate, a short-limbed dwarf, died at 15 hours of age from respiratory distress and a compromised thoracic cavity. Patient 2, the sibling of patient 1 was born at 37 weeks gestation after a pregnancy complicated by polyhydramnios and prenatal ultrasound diagnosis of short-limbed dwarfism. The diagnosis of SEDC was made and, after review of the sibling`s postmortem X-rays, it was felt that she was similarly affected. The family history reveals no history of dwarfism or consanguinity. The SEDC is described as an autosomal dominant form of dwarfism with variable presentation including some cases that have been lethal in the neonatal period. SEDC is now believed to represent a family of collagen II mutations. Sporadic cases that have arisen in families with no history have been ascribed to new heterozygous mutations. Other families in which SEDC and SEMD recurred without a family history most likely represent germ line mosaicism. In these cases molecular studies should be pursued to document a collagen II mutation. We believe that germ line mosaicism is the most plausible explanation for recurrence in our family.« less

Siblings of individuals with first-episode psychosis: understanding their experiences and needs.

PubMed

Sin, Jacqueline; Moone, Nicki; Harris, Paul

2008-06-01

The growth of early intervention in psychosis services (EIPS) has prompted needed research to provide a robust evidence base to underpin practice. The typical service model embraces key psychosocial interventions, including family interventions. A literature review revealed a number of relevant studies that recognized the role of siblings in families affected by severe mental illness or mental impairment, but little was found about the impact of first-episode psychosis on siblings. To address this apparent oversight, we conducted a study to gain an understanding of sibling experiences. Ten siblings (ages 16 to 30) with a brother or sister diagnosed with first-episode psychosis took part in individual semi-structured interviews. The key findings were grouped in regard to emotional impact, relationships in the family, and siblings' roles and coping patterns. The study also revealed that families are able to identify positive gains out of a fundamentally negative experience.

Associations between social understanding, sibling relationship quality, and siblings' conflict strategies and outcomes.

PubMed

Recchia, Holly E; Howe, Nina

2009-01-01

Sibling relationship quality and social understanding (second-order false belief, conflict interpretation, and narrative conflict perspective references) were examined as unique and interactive correlates of sibling conflict behavior in 62 dyads (older M age = 8.39 years and younger M age = 6.06 years). High-quality relationships were associated with positive conflict processes. Younger siblings' second-order false belief scores were negatively associated with constructive conflict strategies, and older siblings' narrative self-referential focus was negatively associated with compromise. Associations between younger children's social understanding (conflict interpretation and narrative perspective references) and siblings' dyadic conflict behavior were moderated by relationship quality. Results suggest that links between social understanding and conflict behavior should be considered in conjunction with the quality of children's relationships.

Neuropsychological functioning of siblings of children with autism, siblings of children with developmental language delay, and siblings of children with mental retardation of unknown genetic etiology.

2007-03-01

Neuropsychological functioning of 30 siblings of children with autism (AU-S), 28 siblings of children with mental retardation of (MR-S), and 30 siblings of children with developmental language delay (DLD-S) was compared. Two siblings, both AU-S, received diagnoses of pervasive developmental disorder (PDD). More siblings with cognitive disabilities were found in DLD-S than in AU-S. However, these differences disappeared after excluding diagnosed siblings or after accounting for family membership. In sum, despite the elevated incidence of PDD among AU-S, the neuropsychological functioning of the remaining siblings did not convey specific characteristics related to the genetic risk associated with autism, in contrast to the cognitive functioning of the DLD-S, which did reflect a genetic risk.

Sibling effects on nutritional status: Intersections of cooperation and competition across development.

PubMed

Helfrecht, Courtney; Meehan, Courtney L

2016-01-01

Examination of sibling effects on nutritional status is complicated by siblings being both alloparents and resource competitors, as well as the extensive changes children undergo across development. To evaluate sibling nutritional effects with consideration of these opposing roles, we use an evolutionary framework rooted in human ontogeny and cooperative breeding. Anthropometric data were collected from 113 Ngandu horticulturalist children (birth-<18 years old).We generated weight-for-age (WAZ), height-for-age (HAZ), and BMI-for-age (BMIZ) z-scores. Nutritional status across developmental risk periods (<2.5, 2.5-<5, 5-<10, and ≥10 years) was assessed using one-way ANOVAs. OLS regression was used to examine interactions between presence of siblings and risk periods. A considerable percentage of Ngandu children are suffering from stunting, underweight, or caloric deficiencies, but many fall within healthy ranges for WAZ (65%), HAZ (60%), and BMIZ (88%). Siblings have significant impacts on children's nutritional status, but their impacts vary by risk period. In general, older siblings (≥5 years old) have positive effects on their same-aged siblings, while younger siblings (<5) negatively affect those between 2.5 and <10 years old. Closely aged siblings do not always represent competitors. In this ecocultural context, those aged ≥5 years old appear to cooperate to improve their siblings' nutritional status. By evaluating the effects of siblings during specific risk periods, we offer a strategy to untangle the intersections of cooperation and competition. Our results add to the growing body of evidence showing benefits to allocare and further demonstrate that even children target their assistance toward vulnerable periods in development. © 2015 Wiley Periodicals, Inc.

Children with PIMD in interaction with peers with PIMD or siblings.

Nijs, S; Vlaskamp, C; Maes, B

2016-01-01

The complex disabilities of children with profound intellectual and multiple disabilities (PIMD) impede their presentation of peer directed behaviours. Interactions with typically developing peers have been observed to be more frequent than those with peers with PIMD. The typically developing peers with whom people with PIMD have frequent contact are their siblings. In this study, the amount of peer directed behaviours was compared between an interaction with a sibling and an interaction with a peer with PIMD. In addition, the attention directing strategies of the siblings, and how these affect the presentation of peer directed behaviours, were examined. Thirteen children and young people with PIMD, who had a typically developing sibling, were identified. For each of these thirteen children, a peer with PIMD and a sibling were selected. The child with PIMD was observed together with a peer with PIMD and together with a sibling. In both conditions, video observations were conducted. A coding scheme for the peer directed behaviours of the children and young people with PIMD and a coding scheme for the attention directing behaviours of the siblings were used. Descriptive, comparative and sequential analyses were conducted. Significantly, more peer directed behaviours of the children with PIMD were observed in the condition with the sibling (30.76%) compared with that of the condition with the peer with PIMD (13.73%). The siblings presented attention directing behaviours in 30% of the time; the most frequently used was nonverbal behaviour. When the siblings presented a combination of verbal and nonverbal attention directing behaviours, they elicited multiple peer directed behaviours in the children and young people with PIMD. Persons with PIMD interact more with their siblings compared with their peers with PIMD. Interacting with siblings may probably be more motivating and encouraging. Presenting a combination of verbal and nonverbal behaviours attracts more attention

Siblings' coping strategies and mental health services: a national study of siblings of persons with schizophrenia.

PubMed

Friedrich, Rose Marie; Lively, Sonja; Rubenstein, Linda M

2008-03-01

This study examined the helpfulness of coping strategies and the relative importance of mental health services in coping with schizophrenia from the perspective of siblings. This article presents selected survey data from a national study of 746 respondents that investigated the impact of schizophrenia on siblings' lives. The authors developed the Friedrich-Lively Instrument to Assess the Impact of Schizophrenia on Siblings (FLIISS), a closed-ended questionnaire that included questions about coping strategies and mental health services. Respondents identified services for the ill sibling, including symptom control, adequate housing, and long-term planning, as more important than direct services for themselves. The top-ranked coping strategies were education about schizophrenia, a supportive family, and seeing the ill sibling suffer less because symptoms were controlled. Understanding that families were not to blame for schizophrenia was the most helpful coping strategy for nearly three-fourths of siblings. Siblings had little contact with providers in the past; yet the majority of siblings wanted providers to be available to answer questions and clarify their role in future care. At the time of the study, respondents provided social support and helped with crises, but few coordinated the total care. Siblings identified multiple ways that providers can support and assist them in coping with the impact of schizophrenia. Education and support for siblings without schizophrenia and services for their ill siblings will become increasingly important for the well-being of siblings as they are faced with the responsibility of being the primary caregivers in the future.

Sibling dynamics and sport expertise.

Hopwood, M J; Farrow, D; MacMahon, C; Baker, J

2015-10-01

Family members are known to be highly influential in the development of sport expertise. To date, much of the research in this area has focused on parents, with less known about sibling influences on expertise. This investigation explored associations between sport expertise, sibling characteristics, and sibling participation in sport and physical activity. Athletes representing three skill levels provided details of sibling characteristics and participation in sport and physical activity via the Developmental History of Athletes Questionnaire. Elite athletes were more likely to be later-born children, while pre-elite and non-elite athletes were more likely to be first-born. Compared with siblings of non-elite athletes, siblings of elite athletes were more likely to have participated in regular physical activity and were more likely to have participated in sport at the pre-elite and elite levels. These results suggest siblings may play a key role in sport expertise development. © 2015 John Wiley & Sons A/S. Published by John Wiley & Sons Ltd.

Efficacy of Sibling Preparation Classes.

To examine the effectiveness of sibling preparation classes to facilitate the adjustment of a firstborn child to the birth of a sibling. Longitudinal study with five measurement occasions: third trimester of the mother's pregnancy and 1, 4, 8, and 12 months after the sibling's birth. Communities in southeastern Michigan. A total of 241 families, including mothers, fathers, and firstborn children. Mothers and fathers completed questionnaires to assess changes in children's adjustment. Parents were also asked about their children's attendance at a sibling preparation class focused specifically on preparation for the newborn. Effects of attendance were tested using linear mixed models. Other than avoidance of the infant, children who attended sibling preparation classes did not differ from children who did not attend. Sibling preparation classes for adjustment after the birth of an infant sibling had few effects on participants.

2013-07-01

The aims of this study were the following: to identify perceptions of patients with anorexia nervosa (AN) and their siblings regarding differential experiences within and external to the family including sibling interactions, parental treatment, relationships with peers and events that are unique to each sibling; (2) to compare how patients and their siblings perceive eating disorder symptoms, parental affection/control, social support and stigma; and (3) to test associations with family functioning for patients with AN and their siblings. A total of 26 patients paired with their siblings were recruited from an Eating Disorder Program and administered standardized instruments measuring different experiences within and external to the family, the impact of eating disorder behaviours, stigma, social support and family functioning. Patients rated high on the differential experience of jealousy in contrast to their siblings. Patients scored higher than their siblings on eating symptoms, whereas siblings scored higher on social support. The impact of AN on the family, stigma towards the individual and family, and social support accounted for 37% of the variance in family functioning from the sibling perspective after controlling for age and gender. Of these variables, impact of AN on the family made the largest contribution. Family-based and sibling-based interventions that aim to reduce the effects of the illness on the sibling relationship and the family are recommended.

Well-being of Sibling Caregivers: Effects of Kinship Relationship and Race.

Namkung, Eun Ha; Greenberg, Jan S; Mailick, Marsha R

2017-08-01

This study examined whether caregiving has a differential effect on the well-being of sibling caregivers relative to other caregiving groups and whether race moderates this effect. Using the National Survey of Midlife Development in the United States, 631 family caregivers (including 61 sibling caregivers) and 4,944 noncaregivers were identified. Hierarchical regression analyses were conducted to estimate the effect of the caregiver-care recipient relationship and its interaction with race on caregivers' well-being (i.e., depressive symptoms, self-rated health, life satisfaction, and perceived control over life). Caregivers in general reported poorer well-being than noncaregivers, but sibling caregivers were less affected by caregiving than parent or spouse caregivers. Among sibling caregivers, caregiving took a significantly greater toll on non-Hispanic White caregivers than those from minority groups with respect to depressive symptoms and life satisfaction. The findings suggest that the experience of sibling caregivers is significantly shaped by their cultural background. © The Author 2016.

Evidence suggests that early life infections, presence of older siblings and furred pets in the household affect the risk of developing allergic diseases through altered microbial exposure. Recently, low gut microbial diversity during infancy has also been linked with later development of allergies. We investigated whether presence of older siblings, furred pets and early life infections affected gut microbial communities at 9 and 18 months of age and whether these differences were associated with the cumulative prevalence of atopic symptoms of eczema and asthmatic bronchitis at 3 years of age. Bacterial compositions and diversity indices were determined in fecal samples collected from 114 infants in the SKOT I cohort at age 9 and 18 months by 16S rRNA gene sequencing. These were compared to the presence of older siblings, furred pets and early life infections and the cumulative prevalence of diagnosed asthmatic bronchitis and self-reported eczema at 3 years of age. The number of older siblings correlated positively with bacterial diversity (p = 0.030), diversity of the phyla Firmicutes (p = 0.013) and Bacteroidetes (p = 0.004) and bacterial richness (p = 0.006) at 18 months. Further, having older siblings was associated with increased relative abundance of several bacterial taxa at both 9 and 18 months of age. Compared to the effect of having siblings, presence of household furred pets and early life infections had less pronounced effects on the gut microbiota. Gut microbiota characteristics were not significantly associated with cumulative occurrence of eczema and asthmatic bronchitis during the first 3 years of life. Presence of older siblings is associated with increased gut microbial diversity and richness during early childhood, which could contribute to the substantiation of the hygiene hypothesis. However, no associations were found between gut microbiota and atopic symptoms of eczema and asthmatic bronchitis during early childhood and

Self-reported behaviour problems and sibling relationship quality by siblings of children with autism spectrum disorder.

PubMed

Hastings, R P; Petalas, M A

2014-11-01

There are few published research studies in which siblings of children with autism spectrum disorder (ASD) provide self-reports about their own behavioural and emotional problems and their sibling relationships. Reliance on parent reports may lead to incomplete conclusions about the experiences of siblings themselves. Siblings 7-17 years and their mothers from 94 families of children with ASD were recruited. Mothers reported on family demographics, the behavioural and emotional problems of their child with ASD, and on their own symptoms of depression. Siblings reported on their relationship with their brother or sister with ASD, and siblings 11+ years of age also self-reported on their behavioural and emotional problems. Compared with normative British data, siblings reported very slightly elevated levels of behavioural and emotional problems. However, none of the mean differences were statistically significant and all group differences were associated with small or very small effect sizes - the largest being for peer problems (effect size = 0.31). Regression analysis was used to explore family systems relationships, with sibling self-reports predicted by the behaviour problems scores for the child with ASD and by maternal depression. Maternal depression did not emerge as a predictor of siblings' self-reported sibling relationships or their behavioural and emotional problems. Higher levels of behaviour problems in the child with ASD predicted decreased warmth/closeness and increased conflict in the sibling relationship. These data support the general findings of recent research in that there was little indication of clinically meaningful elevations in behavioural and emotional problems in siblings of children with ASD. Although further research replication is required, there was some indication that sibling relationships may be at risk where the child with ASD has significant behaviour problems. © 2014 John Wiley & Sons Ltd.

Enhancing sibling relationships to prevent adolescent problem behaviors: theory, design and feasibility of Siblings Are Special.

2013-02-01

Siblings play a significant but neglected role in family socialization dynamics, and focusing on the sibling relationship is a non-stigmatizing point of entry into the family for prevention programming. Siblings are Special (SAS) was designed as a universal program that targets both sibling relationship and parenting mediating processes in middle childhood to prevent behavior problems in adolescence. We describe the theoretical framework underlying SAS, the SAS curriculum, and the feasibility of the program based on a study of 128 middle-childhood aged sibling dyads. Data on the quality of program implementation, program fidelity, siblings' engagement, and ratings of impact indicated the SAS program was acceptable to families and schools, that the curriculum could be implemented with high fidelity, that siblings and parents participated at high levels and were highly engaged, and that, from the perspective of group leaders, school administrators and parents, the program had a positive impact on the siblings.

Fleary, Sasha A.; Heffer, Robert W.

2013-01-01

The purpose of this study was to explore the continuing impact of growing up with an ill sibling on well siblings' late adolescent functioning. Forty late adolescents (M age = 18.78, SD = 0.83), who identified themselves as growing up with an ill sibling, completed a semistructured interview, demographic questionnaire, Personality Assessment Screener, and My Feelings and Concerns Sibling Questionnaire. Participants reported clinically significant problems on some PAS scales, and gender differences were found for acting out and alienation. Significant relationships were reported for communication and social withdrawal and alienation. Both positive and negative themes about the experience were elicited from the responses in the semistructured interview. This study provides evidence for some lingering negative effects of growing up with an ill sibling on well siblings' late adolescent functioning. Additionally, evidence for siblings' development of positive characteristics that may act as protective variables as they face the stressors of late adolescence was also highlighted. PMID:24959574

Objective The familial context plays an important role in psychosocial responses to genetic testing. The purpose of this study was to compare sibling pairs with different combinations of BRCA1/BRCA2 test results on measures of affect, interpersonal responses, and physiological reactions. Design Forty-nine sibling dyads with different combinations of BRCA1/BRCA2 test results (i.e., mixed, positive, negative) completed a questionnaire, and 35 of the dyads also participated in a laboratory-based discussion of genetic testing. Main Outcome Measures The primary outcome variables included participant reports of supportive actions toward their sibling, state anger and anxiety, perceptions of sibling behavior, and electrodermal responses. Results Compared to positive and negative dyads, mixed pairs reported less friendly general support actions, noted more anger, and perceived their sibling to be less friendly and more dominant during the interactions. In comparisons between same-result (i.e., positive, negative) pairs, positive dyads reported more dominant support behaviors and perceived their sibling to be friendlier during the interactions. Conclusion Data suggest that siblings who have different test results may experience more interpersonal strain than siblings who have the same test result. Future research on genetic testing and family relationships can expand upon these findings. PMID:18230020

School Experiences of Siblings of Children with Chronic Illness: A Systematic Literature Review.

Gan, Lucy L; Lum, Alistair; Wakefield, Claire E; Nandakumar, Beeshman; Fardell, Joanna E

Siblings of children with chronic illness have unique experiences that can affect their school functioning, such that they may miss ongoing periods of school, experience difficulties with schoolwork or experience changes in their peer and teacher interactions. This review provides an overview of these siblings' school experiences. Six databases (Medline, PsychINFO, CINAHL, ERIC, Embase and The Cochrane Library) were systematically searched for studies examining the school experiences and peer relationships of siblings of children with chronic illness, as well as school-based interventions for these siblings. Studies were included if they were published in or after 2000 and were published in English. We identified 2137 articles upon initial search. From these, we identified 28 eligible studies examining the school experiences of >1470 siblings of children with chronic illness. Three key themes were identified throughout the reviewed articles. The literature described 1) the psychological impact on siblings at school; 2) decreases in school attendance and academic functioning, and; 3) changes or perceived differences in peer and teacher interactions. Siblings value teacher and peer support, and this support may contribute to better sibling school functioning. Many siblings are socially resilient, yet overlooked, members of the family who may present with psychological, academic and peer related difficulties at school following diagnosis of a brother or sister with chronic illness. Future research is needed to further delineate the sibling school experience to better facilitate the development of targeted sibling support interventions within the school environment.

Jamieson, Lisa; McCully, William

2015-06-13

Phthalates are excipients in drug formulations. However, concerns have been raised about the effects of particular phthalates on reproduction and development. As a result the EMA has introduced guidelines for permitted daily exposure (PDE) limits for certain phthalates. Therefore, the objective of this study was to identify UK licensed medicines that contain the relevant phthalates and determine if they fall within the recommended PDE. The eMC was used to identify which UK licensed medicines contain the phthalates in question. Companies were then contacted for information on the phthalate levels in their products, which was compared with the PDE recommended by the EMA. The eMC search revealed that 54 medicines contained at least one of the phthalates in question. However, only six medicines, namely Asacol 800 mg MR (Warner Chilcott UK), Epilim 200 Gastro-resistant tablets (Sanofi), Prednisolone 2.5 mg and 5 mg Gastro-resistant tablets (Actavis UK), Vivotif (Crucell Italy S.r.l), and Zentiva 200 mg Gastro-resistant tablets (Winthrop Pharmaceuticals UK), were identified as containing levels that exceeded the recommended PDE. These findings indicate that very few UK licensed medicines will be affected by the proposed EMA guidelines. For those medicines identified as exceeding recommendations, these findings highlight the need to instigate a risk-benefit review.

Perceived sibling relationships of sexual minority youth.

PubMed

Toomey, Russell B; Richardson, Rhonda A

2009-01-01

The purpose of this study was to examine the relationships of sexual minority youth and their siblings. The participants were 56 lesbian, gay, bisexual, or transgender individuals ranging in age from 18 to 24 years, who reported information about a total of 107 siblings. Respondents completed a demographic data questionnaire as well as adapted versions of the Sibling Closeness Scale (SCS) and the Sibling Approval of Sexual Behavior Scale (SASBS) to describe their relationship with each of their siblings. Analyses examined birth order and gender in relation to outness to siblings as well as sibling closeness and approval. Results provide information about disclosure of LGBT status to siblings, elements of closeness and acceptance in sibling relationships of sexual minority youth, and the significance of gender and birth order in these sibling relationships.

Relative Power in Sibling Relationships Across Adolescence.

PubMed

Lindell, Anna K; Campione-Barr, Nicole

2017-06-01

During childhood, older siblings typically hold a more powerful position in their relationship with their younger siblings, but these relationships are thought to become more egalitarian during adolescence as siblings begin to prepare for their relationships as adults and as younger siblings become more socially and cognitively competent. Little is known about relationship factors that may explain this shift in power dynamics, however. The present study therefore examined longitudinal changes in adolescents' and their siblings' perceptions of sibling relative power from age 12 to 18 (n = 145 dyads), and examined whether different levels of sibling relationship positivity and negativity, as well as sibling structural variables, indicated different over-time changes in relative power. Multilevel models indicated that adolescents reported significant declines in their siblings' relative power across adolescence, with older siblings relinquishing the most power over time. However, only siblings with less positively involved relationships reported declines in relative power, suggesting that siblings who maintain highly involved relationships may not become more egalitarian during adolescence. © 2017 Wiley Periodicals, Inc.

Variability of age at onset in siblings with familial Alzheimer disease.

Variability of age at onset (AO) of Alzheimer disease (AD) among members of the same family is important as a biological clue and because of its clinical effects. To evaluate which clinical variables influence the discrepancy in AO among affected relatives with familial AD. Clinical genetic project of Spanish kindred with AD conducted by 4 academic hospitals in Madrid, Spain. Age at onset of AD in 162 families and discrepancy in AO in intragenerational and intergenerational affected pairs were analyzed in relation to age, sex, maternal or paternal transmission, pattern of inheritance, and apolipoprotein E genotype. Maternal transmission of AD was significantly more frequent than paternal transmission (P < .001). In 27% of the affected individuals, AO occurred before the patient was 65 years old. Discrepancy in AO among siblings was within 5 years in 44% of the families, 6 to 10 years in 29%, and more than 10 years in 27% (range, 0-22). This discrepancy was independent of the sex of the sibling pairs and was significantly lower with maternal transmission of AD (P = .02). Segregation analysis showed no differences in the inheritance pattern between families with low (< or =5 years) or high (>5 years) AO discrepancy. Age at onset in carriers of the apolipoprotein E epsilon4 allele was slightly younger. However, among siblings, an extra apolipoprotein E epsilon4 allele was not consistently associated with earlier onset of AD. Eighty percent of patients, independent of sex or mode of transmission, were already affected at their parents' reported AO. There is a wide discrepancy in AO in affected siblings that is not clearly explained by a single clinical variable or apolipoprotein E genotype. The interaction of many factors probably determines AO in each affected individual. However, maternal transmission of AD seems to result in a similar AO in offspring, and the risk of developing dementia after the parent's reported AO decreases significantly.

In many families, siblings play important roles in shaping each other's outcomes and experiences across development. In adoptive families, siblings may affect adoptees' feelings about adoption and birth family contact. Among "target adoptees" (i.e., 1 participating adopted individual within adoptive families) with siblings who may have also been adopted or the biological children of the adoptive parents, we examined how adoption experiences and individual adjustment from adolescence into emerging adulthood were associated with sibling relationship dynamics. We present 3 studies using longitudinal, mixed method data within the same overarching sample of adoptive families. Study 1 was a follow-up to Berge et al.'s (2006) study of adolescent adoptees and their adopted siblings with birth family contact; we found evidence of changes in the status of contact collectively experienced by 26 adopted sibling pairs when target adoptees were emerging adults. In Study 2, we found that target adoptees (n = 91) with siblings (adopted or not) who were more involved with target adoptees' birth family contact demonstrated more favorable behavioral outcomes than target adoptees who had uninvolved siblings. Finally in Study 3, for target adoptees with siblings who were also adopted (n = 51), results showed that target adoptees felt more positively about their own adoption when siblings expressed similar positive feelings about individual adoption experiences. Implications of our findings are discussed in terms of the enduring contributions of sibling relationships from childhood into adulthood and the unique ways in which adoptive siblings are important in shaping one another's experiences of adoption.

2010-08-01

The current study examined the role of adolescents' self-regulation as a mediator between sibling relationship quality and adolescent outcomes, after controlling for the quality of the parent-child relationship. Participants were 395 families (282 two parent; 113 single parent) with an adolescent child (M age of child at Time 1 = 11.15, SD = .96, 49% female) who took part in [project name masked for blind review] at both Time 1 and Time 2. Path analysis via structural equation modeling suggested that sibling affection was longitudinally and positively related to self-regulation and prosocial behaviors, and negatively related to externalizing behaviors; while sibling hostility was positively, and having a sister was negatively related to internalizing behaviors (in general, paths were stronger for adolescents from two- vs. single-parent families). There was also evidence that adolescents' self-regulation partially mediated the relation between sibling affection and positive and negative adolescent outcomes. The discussion focuses on the importance of continued research examining the mechanisms through which the sibling relationship influences development during adolescence.

Books for siblings of children having illness or disability.

PubMed

Ahmann, E

1997-01-01

A child's disability or acute or chronic illness has an effect on all family members, including siblings of the affected child. Children's books, fiction and non-fiction, can be used to support siblings by providing information, addressing feelings, offering insight, assuring the child that others have had similar problems, and facilitating coping. Nurses can introduce children and their families to useful books by having books or book covers on display that the child can choose from; providing families with lists of books; and/or assessing the child's needs, interests and reading level, and recommending a specific title.

Enhancing Sibling Relationships to Prevent Adolescent Problem Behaviors: Theory, Design and Feasibility of Siblings Are Special

Feinberg, Mark E.; Sakuma, Kari-Lyn; Hostetler, Michelle; McHale, Susan M.

2012-01-01

Siblings play a significant but neglected role in family socialization dynamics, and focusing on the sibling relationship is a non-stigmatizing point of entry into the family for prevention programming. Siblings are Special (SAS) was designed as a universal program that targets both sibling relationship and parenting mediating processes in middle childhood to prevent behavior problems in adolescence. We describe the theoretical framework underlying SAS, the SAS curriculum, and the feasibility of the program based on a study of 128 middle-childhood aged sibling dyads. Data on the quality of program implementation, program fidelity, siblings’ engagement, and ratings of impact indicated the SAS program was acceptable to families and schools, that the curriculum could be implemented with high fidelity, that siblings and parents participated at high levels and were highly engaged, and that, from the perspective of group leaders, school administrators and parents, the program had a positive impact on the siblings.

The early development of infant siblings of children with autism spectrum disorder: Characteristics of sibling interactions

2018-01-01

Although sibling interactions play an important role in children’s early development, they are rarely studied in very young children with an older brother or sister with autism spectrum disorder (ASD). This study used a naturalistic, observational method to compare interactions between 18-month-old infants and their older sibling with ASD (n = 22) with a control group of 18-month-old infants and their typically developing (TD) older sibling (n = 29). In addition, role (a)symmetry and the influence of gender were evaluated. Sibling interactions in ASD-dyads were characterized by higher levels of negativity. Although somewhat less pronounced in ASD-dyads, role asymmetry was present in both groups, with the older child taking the dominant position. Finally, siblings pairs with an older sister were characterized by more positive behaviours. Since differences in sibling interactions may alter the developmental trajectories of both siblings, these early relationships should be taken into account in future ASD research and interventions.

Psychosocial Adjustment and Sibling Relationships in Siblings of Children with Autism Spectrum Disorder: Risk and Protective Factors.

Walton, Katherine M; Ingersoll, Brooke R

2015-09-01

This study compared sibling adjustment and relationships in siblings of children with Autism Spectrum Disorder (ASD-Sibs; n = 69) and siblings of children with typical development (TD-Sibs; n = 93). ASD-Sibs and TD-Sibs demonstrated similar emotional/behavioral adjustment. Older male ASD-Sibs were at increased risk for difficulties. Sibling relationships of ASD-Sibs involved less aggression, less involvement, and more avoidance than those of TD-Sibs. Partial support for a diathesis-stress conceptualization of sibling difficulties was found for ASD-Sibs. For TD-Sibs, broader autism phenotype (BAP) was related to psychosocial difficulties regardless of family stressors. For ASD-Sibs, BAP was related to difficulties only when family stressors were present. This suggests that having a sibling with ASD may be a protective factor that attenuates the negative impact of sibling BAP.

Many studies have assessed the costs of sibling rivalry in systems where offspring always have competitors, but conclusions about sibling rivalry in these species are restricted to interpreting the cost of changes in the relative level of competition and are often complicated by the expression of potentially costly rivalry related traits. Additionally, the majority of studies focus on early-life sibling rivalry, but the costs of competition can also affect later-life performance. We test a suite of hypothesized immediate (early-life body mass, telomere length, and survival) and delayed (adult reproductive potential and lifespan) costs of sibling rivalry for offspring of differing competitive ability in Seychelles warblers, where most offspring are raised singly and hence competitor success can be compared to a competition-free scenario. Compared to those raised alone, all competing nestlings had lower body mass and weaker competitors experienced reduced survival. However, the stronger competitors appeared to have longer adult breeding tenures and lifespan than those raised alone. We propose that comparisons with competition-free groups, as well as detailed fitness measures across entire lifetimes, are needed to understand the evolution of sibling rivalry and thus individual reproductive strategy in wild systems.

A relational understanding of sibling experiences of children with rare life-limiting conditions: findings from a qualitative study.

Mucopolysaccharidoses (MPS) and Batten disease are rare life-limiting conditions (LLCs) characterised by progressive and permanent physical and cognitive decline. The impact of such conditions on families, and notably on siblings, has not yet been described or documented. This paper presents data from a UK-wide study that sought to understand the family experience of supporting a child with the rare degenerative LLCs of MPS and Batten disease. The aim of this paper is to report sibling experiences related to these rare degenerative and progressive conditions, in order to inform the future development of supportive interventions. Eight siblings of children with MPS (n = 7) and Batten Disease (n = 1) participated in semi-structured qualitative interviews. A card sort technique was utilised to support and engage the children. Siblings are clearly impacted emotionally, pragmatically and relationally by the ill health of another child in the family. The data indicate four key themes which demonstrate impacts on siblings: perceptions of the condition and its symptoms, impact on daily life, emotional consequences and ways of coping. Siblings often had considerable knowledge of the condition and took on important roles in symptom management. However, these experiences were in the context of managing relationships within the family (often protecting parents from an awareness of how much they knew) and relationships at school (including distraction from learning and being bullied by peers). The data highlight how sibling experiences are generated through a combination of negative disability discourses and support through peers and family members. The data indicate how these features shift as a consequence of witnessing the advancement of their brother's or sister's condition and the emotional sequelae of disease progression. Exploration of siblings' experiences of living with such rare progressive and degenerative LLCs suggest the focus of interventions to support this

Background Cognitive deficits have been consistently reported in individuals with bipolar disorder (BD). The cognitive profile of siblings of individuals with BD is, however, less clearly established possibly due to the heterogeneity of neuropsychological measures used in previous studies. The aim of this exploratory study was to assess the cognitive function of siblings of individuals with BD and compare it with that of their first-degree relatives suffering with BD, and healthy controls (HC) using the Cambridge Neuropsychological Test Automated Battery (CANTAB) - a comprehensive and validated computerized cognitive battery. Methods We recruited 23 HC (33.52±10.29 years, 8 males), 27 individuals with BD (34.26±10.19 years, 9 males, 25 BDI, 1BDII and 1 BD-NOS), and 15 of their biologically related siblings (37.47±13.15 years, 4 males). Siblings had no current or lifetime history of mental disorders. Participants performed the CANTAB and completed questionnaires assessing mood and global functioning. Multivariate analyses compared CANTAB measures across the three participant groups. Results Individuals with BD and their siblings were less accurate in a task of sustained attention (Rapid Visual Processing) when compared to HC. Further, individuals with BD displayed pronounced deficits in affective processing (Affective Go/No-Go) compared to HC. There were no cognitive differences between siblings and individuals with BD. After correcting for current depressive symptoms, these results did not reach statistical significance. Conclusions Subthreshold depressive symptoms may be associated with reduced sustained attention in healthy siblings of BD patients. This preliminary result needs to be corroborated by large-scale, longitudinal studies assessing the relationship between cognition and mood in vulnerable individuals. PMID:27179338

[Siblings of prepubesecent anorexic children].

PubMed

Noël, L; de Maynadier, L

2014-10-01

As professionals working in a specialised unit for prepubescent anorexic children, we are very often concerned with the siblings of our young patients who are daily faced with anorexia nervosa. Although it is an undeniable subject of prevention, research on the topic remains scarce. Based on our clinical experience, this article thus proposes to give a few landmarks to health professionals likely to support these siblings in order to prevent anxious and depressive disorders as well as eating disorders. If guided, supported and informed on anorexia nervosa, siblings can adopt adequate coping strategies when confronted to their sibling's anorexic cognitions and behaviours. We also encourage parents to pay close attention to the needs of their other children, especially to remain receptive to the youngest ones or, if unavailable to find adult carers (grandparents, family, friends). We also guide these children, who are eager to help their anorexic sibling, to remain in a brotherly role. Siblings must be informed about anorexia nervosa. Such information enables them to have a better understanding of their sister's thoughts and attitudes. It also leads to a better understanding of the reasons why anorexia has such a significant impact on family routine, among other things by reducing parental availability. Beyond enabling siblings to adopt adequate coping strategies, such provision of support also contributes to the prevention of mental illness and the maintenance of adequate sibling and family relationships.

Toseeb, Umar; McChesney, Gillian; Wolke, Dieter

2018-07-01

Using data from a prospective population based study, the prevalence and psychopathological correlates of sibling bullying in children with and without autism spectrum disorder (ASD) were estimated. There were 475 children with ASD and 13,702 children without ASD aged 11 years. Children with ASD were more likely to be bullied by their siblings compared to those without ASD. They were also more likely than those without ASD to both bully and be bullied by their siblings, which was associated with lower prosocial skills as well as more internalizing and externalizing problems compared to those not involved in any sibling bullying. Interventions to improve social and emotional outcomes in children with ASD should focus on both the affected and the unaffected sibling.

Studies are needed to better understand the broad autism phenotype in young siblings of children with autism. Cognitive, adaptive, social, imitation, play, and language abilities were examined in 42 non-autistic siblings and 20 toddlers with no family history of autism, ages 18-27 months. Siblings, as a group, were below average in expressive language and composite IQ, had lower mean receptive language, adaptive behavior, and social communication skills, and used fewer words, distal gestures, and responsive social smiles than comparison children. Additionally, parents reported social impairments in siblings by 13 months of age. These results suggest that the development of young non-autistic siblings is affected at an early age and, thus, should be closely monitored, with appropriate interventions implemented as needed.

Risk of maltreatment for siblings: Factors associated with similar and different childhood experiences in a dyadic sample of adult siblings.

2018-02-01

Siblings share the same environment and thus potentially a substantial number of risk factors for child maltreatment. Furthermore, the number of siblings and the sibling constellation itself might pose a risk for child maltreatment. Little is known about the likelihood that more than one child in a family is maltreated and which factors increase the risk. This study sought to investigate similarities and differences in maltreatment in siblings and risk factors associated with the maltreatment of more than one child from the same family. Data on maltreatment during childhood and adolescence, family background, and sibling constellation were collected from 870 pairs of siblings. In the dyadic analyses, siblings reported similar maltreatment experiences, especially when any type of maltreatment was considered. Parents' mental health problems were significant predictors for maltreatment of at least one sibling. Father's mental health problems were predictive of maltreatment of both or only the younger sibling, mother's mental health problems of both or only the older sibling. Closeness in age and same gender of siblings did not emerge as a consistent predictor. The increasing number of siblings was a risk factor for any type of maltreatment of both siblings. The results highlight the need for preventive measures for families with a large number of children and with parents with mental health problems as well as a repeated risk assessment of all siblings in a family when one sibling was maltreated.

Social Risk Factors of Black and White Adolescents' Substance Use: The Differential Role of Siblings and Best Friends.

PubMed

Rowan, Zachary R

2016-07-01

Efforts to understand peer influence among adolescents have established the robust relationship between having substance using peers and future substance use. Still, research suggests that peer influence affects different types of adolescents in different ways. Black adolescents may be less susceptible to friends compared to white adolescents and possess stronger family-orientation, suggesting that siblings may affect deviance of Black adolescents whereas friends will have a minimal impact. This study used data from the first two waves of the National Longitudinal Study of Adolescent to Adult Health to evaluate the relative strength of best friend and siblings' influence as risk factors for Black and White adolescents' alcohol and cigarette use. Approximately 182 Black sibling pairs (37 % male) and 657 white sibling pairs (46 % male) that ranged in ages from 11 to 19 were in the longitudinal analyses for the current study. The findings demonstrated that sibling and best friends' substance use explained white adolescents' cigarette and alcohol use, whereas Black adolescents' cigarette and alcohol use was predominantly explained by siblings' substance use. Ultimately, the results indicated the nuanced role that two types of peers have in explaining variation in substance use across Black and White adolescents.

This study explored the links between having older siblings who get drunk, satisfaction with the parent-adolescent relationship, parental monitoring, and adolescents' risky drinking. Regression models were conducted based on a national representative sample of 3725 8th to 10th graders in Switzerland (mean age 15.0, SD = .93) who indicated having older siblings. Results showed that both parental factors and older siblings' drinking behaviour shape younger siblings' frequency of risky drinking. Parental monitoring showed a linear dose-response relationship, and siblings' influence had an additive effect. There was a non-linear interaction effect between parent-adolescent relationship and older sibling's drunkenness. The findings suggest that, apart from avoiding an increasingly unsatisfactory relationship with their children, parental monitoring appears to be important in preventing risky drinking by their younger children, even if the older sibling drinks in such a way. However, a satisfying relationship with parents does not seem to be sufficient to counterbalance older siblings' influence.

The aim of the present study was to examine whether adolescents of Moroccan and Dutch origin differ concerning sibling relationship quality and to examine whether the associations between quality of the sibling relationship and level and change in externalizing and internalizing problem behavior are comparable for Moroccan and Dutch adolescents. Five annual waves of questionnaire data on sibling support and conflict as well as externalizing problems, anxiety and depression were collected from 159 ethnic Moroccan adolescents (Mage = 13.3 years) and from 159 ethnic Dutch adolescents (Mage = 13.0 years). Our findings demonstrated significant mean level differences between the Moroccan and Dutch sample in sibling relationship quality, externalizing problems, and depression, with Moroccan adolescents reporting higher sibling relationship quality and less problem behavior. However, effects of sibling relationship quality on externalizing problems, anxiety, and depression were similar for the Moroccan and Dutch samples. Sibling support was not related to level of externalizing problems, nor to changes in externalizing problems, anxiety, and depression. Additionally, more sibling conflict was related to a higher starting level of and faster decreases in problem behaviors. Our results support the ethnic equivalence model, which holds that the influence of family relationships is similar for different ethnic groups. Moreover, sibling support and conflict affect both the level and the fluctuations in problem behavior over time in specific ethnic groups similarly. Implications for future studies and interventions are subsequently discussed.

The subtle intracapsular survival of the fittest: maternal investment, sibling conflict, or environmental effects?

Developmental resource partitioning and the consequent offspring size variations are of fundamental importance for marine invertebrates, in both an ecological and evolutionary context. Typically, differences are attributed to maternal investment and the environmental factors determining this; additional variables, such as environmental factors affecting development, are rarely discussed. During intracapsular development, for example, sibling conflict has the potential to affect resource partitioning. Here, we investigate encapsulated development in the marine gastropod Buccinum undatum. We examine the effects of maternal investment and temperature on intracapsular resource partitioning in this species. Reproductive output was positively influenced by maternal investment, but additionally, temperature and sibling conflict significantly affected offspring size, number, and quality during development. Increased temperature led to reduced offspring number, and a combination of high sibling competition and asynchronous early development resulted in a common occurrence of "empty" embryos, which received no nutrition at all. The proportion of empty embryos increased with both temperature and capsule size. Additionally, a novel example ofa risk in sibling conflict was observed; embryos cannibalized by others during early development ingested nurse eggs from inside the consumer, killing it in a "Trojan horse" scenario. Our results highlight the complexity surrounding offspring fitness. Encapsulation should be considered as significant in determining maternal output. Considering predicted increases in ocean temperatures, this may impact offspring quality and consequently species distribution and abundance.

Technology-dependent (TD) children require complex care and are dependent on medical technology. Approximately 75% of families, in the United States, who are caring for a TD child, also care for a well child. Well siblings are likely to be affected by the experience of living with a TD sibling as the process of family normalization is described as a family affair. The experiences of well siblings are not well described. The purpose of this qualitative analysis was to describe the experiences of well siblings who are living in a family with a TD child. Mothers were interviewed about the experiences of their well children and were digitally audio recorded. The interviews were transcribed, and content analysis was conducted. Content analysis from the interviews revealed the major themes of well sibling adjustment within the family unit, upside (altruistic, prosocial behaviors) and downside (negative internal and external processing behaviors). These results can be applied to advance the delivery of family nursing care offered to these families.

Examine general emotion expression and sibling-parent emotion communication among Latino and non-Latino white (NLW) siblings of children with intellectual disabilities (ID) and matched comparisons. 200 siblings (ages 8-15 years) completed the newly developed Sibling-Parent Emotion Communication Scale and existing measures of general emotion expression and psychosocial functioning. Preliminary analyses evaluated scale psychometrics across ethnicity. Structure and internal consistency of the emotion expression and communication measures differed by respondent ethnicity. Latino siblings endorsed more general emotion expression problems and marginally lower sibling-parent emotion communication than NLW siblings. Siblings of children with ID reported marginally more general emotion expression problems than comparisons. Emotion expression problems and lower sibling-parent emotion communication predicted more internalizing and somatic symptoms and poorer personal adjustment, regardless of ID status. Siblings of children with ID endorsed poorer personal adjustment. Cultural differences in emotion expression and communication may increase Latino siblings' risk for emotional adjustment difficulties.

Sibling jealousy and aesthetic ambiguity in Austen's Pride and Prejudice.

PubMed

Hanly, Margaret Ann Fitzpatrick

2009-04-01

Jane Austen's most popular novel, Pride and Prejudice (1813), illuminates and is illuminated by psychoanalytic aesthetics. When Austen dramatizes unconscious oedipal/sibling rivalries, irony acts as a type of aesthetic ambiguity (E. Kris 1952). A psychoanalytic perspective shows that Austen uses a grammar of negatives (negation, denial, minimization) to achieve the dual meanings of irony, engaging the reader's unconscious instinctual satisfactions, while at the same time protecting the reader from unpleasant affects. Austen's plot, which portrays regressions driven by sibling jealousy, reveals that a new tolerance of remorse and depression in her heroine and hero leads to psychic growth.

Siblings may support each other, but also reveal fierce rivalry and mutual aggression. Supportive sibling relationships have been linked to the development of psychosocial competence of children. In the present longitudinal study, we will focus on the development of perceived support in sibling dyads and on the influence of sibling support and sibling problem behavior on psychosocial adjustment in adolescence. In a three-wave longitudinal sample of 285 Dutch families with two adolescent children (11- to 15-year-olds), these two siblings judged the support perceived from each other. In addition, they themselves and their parents judged their internalizing and externalizing problem behaviors. The relation of sibling support and sibling problem behavior with internalizing and externalizing problem behaviors was examined while controlling for support from parents and friends and, over time, controlling for the autoregressive effects of problem behavior. Support perceived from a sibling is mostly negatively related to externalizing problems; sibling problem behavior is strongly related to internalizing problems. Differential developmental trajectories of adolescents' adjustment are associated with siblings' support and problem behavior. The results indicate that adolescents' relationships with both older and younger siblings are characterized by modeling processes.

This study examined communication interaction patterns when one sibling had a developmental disability as well as the role of communication skills in sibling relationship quality. Thirty sibling dyads were categorized into one of three communication status groups: emerging, context-dependent, and independent communicators. Independent communicators and their siblings did not differ in terms of syntactic complexity but typically developing siblings dominated the interaction and exhibited greater lexical diversity regardless of communication status. Communication status did not impact the warmth/closeness, rivalry, or conflict in the sibling relationship, but siblings of independent communicators engaged in the greatest amount of helping and managing behaviors. These results represent a first step in understanding the role of communication skills in the sibling relationship for families of children with disabilities.

Siblings of individuals with Smith-Magenis syndrome: an investigation of the correlates of positive and negative behavioural traits.

Smith-Magenis syndrome (SMS) is a neurodevelopmental disorder that affects approximately one out of 25,000 births worldwide. To date, no research has been conducted to investigate how having an individual with SMS in a family is a positive or negative influence on siblings. To investigate this question we conducted a study involving 79 siblings and 60 parents of individuals with SMS to assess perceptions of how having a sibling with SMS positively and negative influence siblings' behavioural traits. Our findings show that age of siblings of individuals with SMS was associated with a significant increase in positive behavioural traits and a significant decrease in negative behavioural traits. Additionally, siblings who perceive benefits from having a sibling with SMS demonstrate significantly more positive behavioural traits and significantly fewer negative behavioural traits. Parents accurately assess the changes in sibling behavioural traits with age, and parents who perceive their child as having experienced benefits from the sibling relationship report that siblings demonstrate significantly more positive behavioural traits and significantly fewer negative behavioural traits. Our research shows that although individuals experience difficulties as a result of having a sibling with SMS, overall, siblings tend to fare well and parents appreciate both the positive and negative behavioural effects that result from having a sibling with SMS. © 2012 The Authors.

The contribution of childhood sibling relationships to adult sibling relationships and intention to provide care was investigated in a sample in which one member of each dyad had Down syndrome. Thirty-nine adult siblings of an adult with Down syndrome who had participated in a study of sibling relationships in childhood/adolescence provided data about the quality of current relationships and of their intention to provide care for their brother/sister with Down syndrome in the future. Only behavior problems in the child with Down syndrome predicted warmth of the current adult relationship. Although adult sibling relationships were reported to be warm, the quality of neither the current nor the past relationship was associated with the reported intention to provide care.

Maternal perceptions of sibling adaptation in Korean families of children with Down syndrome.

It is estimated that more than 500 infants with Down syndrome (DS) are born each year in Korea. DS affects not only these individuals, but family members as well. Some siblings deal successfully with the challenges of living with a child with DS and adapt well while others struggle or fail to adapt. The aims of this descriptive study were to explore how Korean mothers of children with DS perceive the adaptation of their typically developing (TD) children aged 4 to 19 and how family variables contribute to sibling adaptation. This descriptive, cross-sectional study was conducted with 105 Korean mothers. Most mothers indicated that their TD children were not experiencing psychological or behavioural problems; however, many described problems in the sibling relationship. It was found that family factors (i.e. condition management effort, condition management ability, child's daily life, parental mutuality, family hardiness and social support) were strong predictors of sibling psychological, behavioural and relational adaptation. Demographic characteristics of the child with DS, the mother and the family appeared to significantly influence sibling adaptation. These findings highlight the importance of familial contexts in understanding sibling adaptation. Knowledge of family factors associated with better adaptation in Korean siblings of child with DS will facilitate the development of culturally appropriate interventions for these children and their families. In addition, an awareness of demographic characteristics associated with sibling adaptation will help health care professionals identify siblings who are at increased risk of experiencing difficulties in adapting. © 2014 MENCAP and International Association of the Scientific Study of Intellectual and Developmental Disabilities and John Wiley & Sons Ltd.

Sibling Influence on Mexican-Origin Adolescents’ Deviant and Sexual Risk Behaviors: The Role of Sibling Modeling

2013-01-01

Purpose A growing body of research indicates that siblings uniquely influence each other’s health risk behaviors during adolescence and young adulthood. Mechanisms underlying these associations, however, are largely unknown because they are rarely tested directly. The present study addressed this gap by examining the role of sibling modeling in explaining changes in Mexican-origin youths’ deviant and sexual risk behaviors over time. Methods The sample included 380 Mexican-origin siblings (older sibling age: M = 21.18, SD = 1.59; younger sibling age: M = 18.19, SD = .46) from (N = 190) families. Participants provided self-reports of their sibling relationship qualities, including modeling, as well as their engagement in deviant and sexual risk taking behaviors in two home interviews across a two-year span. Results A series of residualized regression models revealed that younger siblings’ perceptions of modeling moderated the links between older siblings’ deviant and sexual risk behaviors and younger siblings’ subsequent behaviors in those same domains. Specifically, high levels of modeling predicted stronger associations between older siblings’ earlier and younger siblings’ later risk behaviors controlling for younger siblings’ earlier behaviors as well as variables that have been used as proxies for social learning in previous research. Conclusions Social learning mechanisms, especially modeling, are salient processes through which older siblings transmit norms and expectations regarding participation in health risk behaviors. Future research should continue to explore the ways in which siblings influence each other because such processes are emerging targets for intervention and prevention. PMID:24287013

Integrating Parents' Views on Sibling Relationships to Tailor an Evidence-based Parenting Intervention for Sibling Conflict.

Pickering, John A; Sanders, Matthew R

2017-03-01

Parents play a crucial role in the development of their children's relationships with their siblings. Despite this, relatively few evidence-based parenting programs exist that specifically offer parents the strategies and techniques they desire and require for managing their children's sibling relationships. One way of bridging this gap is to design a tailored parenting intervention for sibling relationships that incorporates the parent voice in various aspects of program design. The current study recruited a convenience sample of 409 Australian parents to complete an online survey relating to their views on difficult sibling behaviors and what, if any, help they desire in dealing with the issue. The majority of respondents were Caucasian, middle- to upper-class mothers. Respondents predominantly attributed the causes of sibling conflict to their child's internal traits, but expressed strong desire for assistance with managing behavioral problems, especially when sibling relationships were marked by physical aggression. Respondents reported high levels of acceptability for positive, rather than punitive, parenting strategies and showed a clear preference for parenting interventions delivered in easy-to-access formats. The findings are interpreted in the context of guiding the development of a tailored parenting intervention for enhancing sibling relationships and reducing conflict. © 2015 Family Process Institute.

The SAO Catalog of about 260,000 stars was studied to arrive at a sample of 'sibling', sun-like G-stars whose possible planetary systems' intelligent beings might feel drawn to single out each other for directional listening and broadcasting. A set of mostly untabulated sibling candidate stars can be defined, given a direction and a small solid angle that are mutually interesting to members of that set, so that overlapping broadcast/receiving cones can be selected on the basis of commonality. It is suggested that the double cone about the direction of the galactic center, whose half angle is 1/137 radian, is an almost inevitable choice in which sending and receiving with current technology can reach to about 1 kpsc, yielding an estimated 1000 G-star sibling candidates.

Links between sibling relationships, mother-partner, and parent-child relationships were studied in a longitudinal community sample of 3681 sibling pairs. Individual differences in sibling relationship quality were related to mother-partner affection and hostility assessed 4 years earlier, to contemporary parent-child negativity, and to indices of social adversity. Evidence for both direct and indirect pathways (via parent-child relations) linking mother-partner and sibling relations were found. Comparisons of prediction for non-stepfamilies and stepfather families showed similarities in patterns of association, but also differences: In stepfather families, mother-partner hostility was unrelated to parent-child negativity and sibling relationship quality. Both positivity and negativity towards young siblings decreased with the age of older siblings, and older sisters were more positive than older brothers.

The sibling relationship has been deemed the quintessential "love-hate relationship." Sibling relationships have also been found to have both positive and negative impacts on the adjustment of youth. Unlike previous research, however, the present study examined the associations between siblings' positive and negative body-related disclosures with relationship quality and body-esteem. Additionally, ordinal position, individual sex, and sibling sex composition were tested as moderators. Participants included 101 predominantly White and middle class adolescent sibling dyads (54 % female adolescents, with relatively equal sibling gender compositions). Older siblings were, on average, 16.46 (SD = 1.35) years old with younger siblings an average of 13.67 (SD = 1.56) years. Adolescents completed questionnaires and data were analyzed using Actor-Partner Interdependence Modeling, which focused on disclosure to and from dyad members. In general, sibling body-related disclosure was positive for the quality of the sibling relationship, regardless of the valance of disclosure. Also, adolescents' body esteem was greater when adolescents reported disclosing (i.e., actor-effects) about positive or negative body issues to their siblings (particularly for females). Conversely, when adolescents received positive or negative body-related disclosures from their siblings (i.e., partner-effects), adolescents reported lower levels of body esteem (particularly for girls and younger siblings). Thus, the impact of body-related disclosure on adolescents' feelings of body esteem appear to be associated more with whether they are the discloser or the one being disclosed to, while the impact on the quality of the relationship has simply more to do with whether or not they are generally disclosing to one another.

Siblings of schizophrenia patients are from the patient's perspective important support providers, but most studies on family burden have focused on the parental role. This study aims to develop a detailed analysis of the psychological aspects of having a sibling with schizophrenia. We did a qualitative study with audiotaped semistructured interviews of 16 siblings. The reliability of the inductive categorization of data was high. A unifying theme appeared to be an emotional sibling bond characterized by feelings of love, sorrow, anger, envy, guilt, and shame. The major categories linked to coping with the situation were avoidance, isolation, normalization, caregiving, and grieving. A third major theme consisted of a fear of possible schizophrenia heredity. The siblings described concerns about the impact of a family history of psychiatric illness, a fear of becoming mentally ill, and reflections about "bad genes." Our findings support earlier findings of coping patterns but complement them by providing a model that includes awareness of genetic vulnerability as an important part of siblings' subjective burden.

The purpose of the present study was to investigate the behavioral problems and parenting style among children with autism and their siblings in an ethnic Chinese population. A total of 151 children with DSM-IV autistic disorder, aged 3-12, 134 siblings without autism, and 113 normally developing controls were recruited. Both parents reported their parenting styles and psychological status and mothers also reported children's behavioral problems. Children with autism had significantly more severe behavioral problems and obtained less affection and more overprotection and authoritarian controlling from their parents than the other two groups. Compared to the controls, unaffected siblings showed some behavioral problems, and obtained less maternal care. Withdrawal and attention, social, and thought problems were the most associated behavioral syndromes to distinguish children with autism from those without. In addition to children with autism, who have a wide range of behavioral problems and impaired parent-child interactions, their siblings may be at risk for such problems.

Summary Burns caused by exhaust systems in children may be associated with considerable morbidity. Current epidemiological data varies, but no data are available for the UK population. We aim to identify the pattern of exhaust-related burns affecting children who presented to a regional centre for paediatric burn care in the UK. Patients who sustained burns related to exhaust mechanisms between May 2005 and August 2012 were identified via the departmental database. Data collected included patient demographics, burn injury information, management and outcomes. Thirty-nine patients sustained 43 burns from contact with exhaust mechanisms, and the majority were less than 5 years of age. 77% of the patients were male. Burns affected critical areas such as the hands and feet in 26% of cases. Most burns involved a total body surface area of ≤1% and were partial thickness in depth. Thirty-three percent of patients required operative intervention. Time to heal was less than 3 weeks in 69% of cases and 3 patients healed with hypertrophic scarring. The majority of burns were small in size and partial thickness in depth. Most were treated conservatively and healed with low complication rates. More than 1 in 5 injuries involved critical burn areas, highlighting the potential for considerable morbidity. The age profile in our study contrasted with other results worldwide. Our study highlights the need for vigilant supervision of children around motorcycles. We recommend the wearing of protective long trousers when riding motorcycles and the fitting of external shields to motorcycle exhaust pipes. PMID:28149228

Background Schizophrenia aggregates in families and accurate diagnoses are essential for genetic studies of schizophrenia. In this study, we investigated whether siblings of patients with schizophrenia can be identified as free of any psychotic disorder using only register information. We also analyzed the emergence of psychotic disorders among siblings of patients with schizophrenia during seven to eleven years of follow-up. Methods A genetically homogenous population isolate in north-eastern Finland having 365 families with 446 patients with a diagnosis of schizophrenia was initially identified in 1991 using four nationwide registers. Between 1998 and 2002, 124 patients and 183 siblings in 110 families were contacted and interviewed using SCID-I, SCID-II and SANS. We also compared the frequency of mental disorders between siblings and a random population comparison group sample. Results Thirty (16%) siblings received a diagnosis of psychotic disorder in the interview. 14 siblings had had psychotic symptoms already before 1991, while 16 developed psychotic symptoms during the follow-up. Over half of the siblings (n = 99, 54%) had a lifetime diagnosis of any mental disorder in the interview. Conclusion Register information cannot be used to exclude psychotic disorders among siblings of patients with schizophrenia. The high rate of emergence of new psychotic disorders among initially healthy siblings should be taken into account in genetic analysis. PMID:16448569

Dermatoglyphic anomalies and neurocognitive deficits in sibling pairs discordant for schizophrenia spectrum disorders.

Rosa, Araceli; Cuesta, Manuel J; Peralta, Víctor; Zarzuela, Amalia; Serrano, Fermín; Martínez-Larrea, Alfredo; Fañanás, Lourdes

2005-12-15

The neurodevelopmental hypothesis of schizophrenia suggests that adverse genetic loading in conjunction with environmental factors early in fetal life causes a disruption of neural development, decades before the symptomatic manifestation of the disease. Neurocognitive deficits have been observed early on the course of schizophrenia, and their association with an early developmental brain lesion has been postulated. Dermatoglyphics have been analyzed in schizophrenia as markers of prenatal brain injury because of their early fetal ontogenesis and susceptibility to the same environmental factors that can also affect cerebral development. The aim of our study was to conduct a comparative examination of neurocognitive functions and dermatoglyphic variables in 89 sibling pairs discordant for schizophrenia spectrum disorders. Therefore, we investigated the association between these two markers to explore the prenatal origin of cognitive deficits in schizophrenia. The affected siblings were significantly impaired on all the cognitive variables assessed (Wisconsin Card Sorting Test, Trail Making Test and Continuous Performance Test) and had a greater number of dermatoglyphic anomalies. These results suggest the influence of intrauterine environmental factors in the siblings affected with schizophrenia. However, we did not detect a significant association between these two vulnerability markers in the schizophrenic patients, suggesting the role of genetic or late environmental factors in the origin of the neurocognitive deficits found in these patients.

Patients with previous polio represent a challenge for neurological rehabilitation. We examined 168 previous polio patients and 239 of their siblings, the patients either from the 1950-1954 epidemic cohort, or from a cohort of hospital-admitted rehabilitation patients. Ninety-four paralytic patients and 74 non-paralytic patients were included. All patients and siblings answered the same questionnaires for socioeconomic and health factors and chi-square comparisons were performed. Previous polio did not affect the level of education. Both patients and siblings rated their educational options to have been good. Significantly less patients were full-time employed at the age of 40 years compared to their siblings (P=0.015). This was the result of a lower full-time employment rate amongst the paralytic patients, only 52% of this group being employed full-time. Male patients and paralytic patients reported to have experienced reduced professional options. More patients were living alone compared to their siblings (P=0.035). The perception of general health was lower amongst patients than siblings, as was assessment of total life situation and patients reported more frequently symptoms like pain and tiredness. In conclusion, previous polio had not lowered the polio patients' educational status, but fewer patients were employed full-time at the age of 40 years.

Objective The objectives of this review are to highlight the impact of the first decade of high-risk (HR) infant sibling work in autism spectrum disorder (ASD) and to identify potential areas of translational focus for the next decade of research. Method A group of clinicians and researchers in ASD working both inside and outside of the HR design met on a regular basis to review the infant sibling research, and came to an agreement on areas that had changed clinical practice and areas that had the potential to change practice with further research. The group then outlined several methodological and translational challenges that must be addressed in the next decade of research if the field is to reach its potential. Results The review concluded that the HR design has yielded an understanding that ASD often, but not always, begins to emerge between 6 and 18 months, with early signs affecting social communication. Research using the HR design has also allowed a better understanding of the sibling recurrence risk (between 10% and 20%). Emerging areas of interest include the developmental trajectories of social communications skills in the early years, the expression of a milder phenotype in siblings not affected with ASD, and the possibility that early intervention with infant siblings may improve outcomes for those with ASD. Important challenges for the future include linking screening to intervention, collecting large sample sizes while ensuring cross-site reliability, and building in capacity for replication. Conclusion Although there are significant methodological and translational challenges for high-risk infant sibling research, the potential of this design to improve long-term outcomes of all children with ASD is substantial.

Whiteman, Shawn D; Becerra, Julia M; Killoren, Sarah E

Siblings are important sources of social influence throughout childhood and adolescence. Nevertheless, the processes by which siblings influence one another remain relatively unexplored. We highlight two theories of sibling influence-sibling deidentification and social learning-that offer insights as to how and why siblings develop similar and different attributes, attitudes, and behaviors. Recognizing the need to move past post hoc explanations, we suggest several directions for how these two influence processes can be measured directly in future work. Research on sibling influence also can be improved by integrating these theories and attending to their domains of influence.

Disclosure, or revealing personal information to others, is important for the development and maintenance of close relationships (Jourard, 1971; Rotenberg, 1995). More recently within developmental psychology, however, the focus has been the study of adolescent disclosure to parents as a means of information management regarding their daily activities. This research assumes that a) disclosure between multiple adolescents and parents within the same family are similar, and b) only information transmitted from adolescents to parents is important for adolescent well-being. Thus, this article presents the findings of 2 within-family studies to investigate differences in the amount and social domain (Smetana, 2006; Turiel, 2002) of youth disclosure to mothers versus siblings, and the influence of disclosure to siblings on relationship quality and youth emotional adjustment. Study 1 utilized 101 sibling dyads with youth ranging in age from 11-21 years, but all siblings living together. Study 2 investigated a sample of 58 sibling dyads in which all first-borns were first-year college students and all second-borns were in high school. All participants completed questionnaire measures to assess study variables. Findings revealed that while youth disclosed more to mothers than siblings, this difference disappears by emerging adulthood, particularly depending on the domain of the issue. Additionally, while greater disclosure among siblings was positive for the quality of the relationship, sibling disclosure was differentially associated with emotional adjustment depending on whether youth were the disclosers or being disclosed to, the domain of the issues disclosed, and the gender composition of the dyad.

'The overall quality of my life as a sibling is all right, but of course, it could always be better'. Quality of life of siblings of children with intellectual disability: the siblings' perspectives.

Moyson, T; Roeyers, H

2012-01-01

The concept of family quality of life is becoming increasingly important in family support programmes. This concept describes the quality of life of all family members and the family system as a whole, but only the opinion of the parents has been included. The opinion of the siblings has been incorporated in the opinions of the parents, although research has shown that there is discordance between parents' and siblings' reports. The principal goal of this study is to investigate how young siblings of children with intellectual disability define their quality of life as a sibling. As we were more concerned with understanding the experience of being a sibling from the siblings' own frame of reference, we opted for a qualitative research design and more specifically used in-depth, phenomenology-based interviews. Data were sorted by means of a process of continuously comparing the codes according to the principles of grounded theory. Siblings described the following nine domains as domains of sibling quality of life: joint activities, mutual understanding, private time, acceptance, forbearance, trust in well-being, exchanging experiences, social support and dealing with the outside world. This study shows not only that siblings can define their quality of life, but also that this definition of sibling quality of life differs from the family quality of life concept. Therefore, it may be not only a valuable addition to the family quality of life concept but also an appropriate concept to describe siblings' experience. © 2011 The Authors.

Familial studies and reports of co-occurrence of gender identity disorder (GID) within a family may help to clarify the question of whether transsexualism is a familial phenomenon. In a sample of 995 consecutive transsexual probands (677 male-to-female [MF] and 318 female-to-male [FM]), we report 12 pairs of transsexual non-twin siblings (nine pairs of MF siblings, two pairs of MF-FM siblings, and one pair of FM siblings). The present study doubles the number of case reports of co-occurrence of transsexualism in non-twin siblings available in the literature. According to our data, the probability that a sibling of a transsexual will also be transsexual was 4.48 times higher for siblings of MF than for siblings of FM transsexual probands, and 3.88 times higher for the brothers than for the sisters of transsexual probands. Moreover, the prevalence of transsexualism in siblings of transsexuals (1/211 siblings) was much higher than the range expected according to the prevalence data of transsexualism in Spain. The study suggests that siblings of transsexuals may have a higher risk of being transsexual than the general population, and that the risk is higher for brothers than sisters of transsexuals, and for siblings of MF than FM transsexuals. Nevertheless, the risk is low.

Plasma cytokine profiling in sibling pairs discordant for autism spectrum disorder

PubMed Central

2013-01-01

Objective Converging lines of evidence point to the existence of immune dysfunction in autism spectrum disorder (ASD), which could directly affect several key neurodevelopmental processes. Previous studies have shown higher cytokine levels in patients with autism compared with matched controls or subjects with other developmental disorders. In the current study, we used plasma-cytokine profiling for 25 discordant sibling pairs to evaluate whether these alterations occur within families with ASD. Methods Plasma-cytokine profiling was conducted using an array-based multiplex sandwich ELISA for simultaneous quantitative measurement of 40 unique targets. We also analyzed the correlations between cytokine levels and clinically relevant quantitative traits (Vineland Adaptive Behavior Scale in Autism (VABS) composite score, Social Responsiveness Scale (SRS) total T score, head circumference, and full intelligence quotient (IQ)). In addition, because of the high phenotypic heterogeneity of ASD, we defined four subgroups of subjects (those who were non-verbal, those with gastrointestinal issues, those with regressive autism, and those with a history of allergies), which encompass common and/or recurrent endophenotypes in ASD, and tested the cytokine levels in each group. Results None of the measured parameters showed significant differences between children with ASD and their related typically developing siblings. However, specific target levels did correlate with quantitative clinical traits, and these were significantly different when the ASD subgroups were analyzed. It is notable that these differences seem to be attributable to a predisposing immunogenetic background, as no other significant differences were noticed between discordant sibling pairs. Interleukin-1β appears to be the cytokine most involved in quantitative traits and clinical subgroups of ASD. Conclusions In the present study, we found a lack of significant differences in plasma-cytokine levels between

Bacteria can secrete a wide array of antibacterial compounds when competing with other bacteria for the same resources. Some of these compounds, such as bacteriocins, can affect bacteria of similar or closely related strains. In some cases, these secretions have been found to kill sibling cells that belong to the same colony. Here, we present experimental observations of competition between 2 sibling colonies of Paenibacillus dendritiformis grown on a low-nutrient agar gel. We find that neighboring colonies (growing from droplet inoculation) mutually inhibit growth through secretions that become lethal if the level exceeds a well-defined threshold. In contrast, within a single colony developing from a droplet inoculation, no growth inhibition is observed. However, growth inhibition and cell death are observed if material extracted from the agar between 2 growing colonies is introduced outside a growing single colony. To interpret the observations, we devised a simple mathematical model for the secretion of an antibacterial compound. Simulations of this model illustrate how secretions from neighboring colonies can be deadly, whereas secretions from a single colony growing from a droplet are not. PMID:19129489

In recent years, rates of vaccination have been declining. Whether this phenomenon disproportionately affects children with autism spectrum disorder (ASD) or their younger siblings is unknown. To investigate if children after receiving an ASD diagnosis obtain their remaining scheduled vaccines according to the Advisory Committee on Immunization Practices (ACIP) recommendations and to compare the vaccination patterns of younger siblings of children with ASD with the vaccination patterns of younger siblings of children without ASD. This investigation was a retrospective matched cohort study. The setting was 6 integrated health care delivery systems across the United States within the Vaccine Safety Datalink. Participants were children born between January 1, 1995, and September 30, 2010, and their younger siblings born between January 1, 1997, and September 30, 2014. The end of follow-up was September 30, 2015. Recommended childhood vaccines between ages 1 month and 12 years. The proportion of children who received all of their vaccine doses according to ACIP recommendations. The study included 3729 children with ASD (676 [18.1%] female), 592 907 children without ASD, and their respective younger siblings. Among children without ASD, 250 193 (42.2%) were female. For vaccines recommended between ages 4 and 6 years, children with ASD were significantly less likely to be fully vaccinated compared with children without ASD (adjusted rate ratio, 0.87; 95% CI, 0.85-0.88). Within each age category, vaccination rates were significantly lower among younger siblings of children with ASD compared with younger siblings of children without ASD. The adjusted rate ratios varied from 0.86 for siblings younger than 1 year to 0.96 for those 11 to 12 years old. Parents who had a child with ASD were more likely to refuse at least 1 recommended vaccine for that child's younger sibling and to limit the number of vaccines administered during the younger sibling's first year of life

Sibling relational aggression is an important but understudied dimension of sibling relationships that has potential implications for adolescents' adjustment. This study examined the longitudinal associations between being the target of sibling relational aggression and adolescent adjustment (i.e., depressive symptoms, risky behavior, self-worth, and romantic competence) among younger and older siblings over a three-year period in adolescence. The moderating roles of birth order, sibling gender, and sibling dyad gender constellation also were tested. Participants were 196 European American adolescent (firstborn-secondborn) sibling pairs who were 16.47 years (SD = 0.80) and 13.88 years (SD = 1.15) of age, respectively, at the onset of this study. Data were collected separately from each sibling during home interviews. Multilevel models revealed that being the target of sibling relational aggression was associated with all four adjustment outcomes at the between-person level, and with risky behavior and romantic competence at the within-person level. However, some of these effects were moderated by sibling dyad characteristics. Although often overlooked in the literature on adolescence, sibling relationship dynamics play a key role in youth development and adjustment.

Fucosidosis is a rare lysosomal storage disorder due to deficiency of fucosidase enzyme, with around 100 cases reported worldwide. Here, we describe the clinical and imaging features in two siblings with fucosidosis. An 8-year-old girl presented with global developmental delay, followed by regression of acquired milestones from 3 years of age with bipyramidal, extrapyramidal involvement, coarse facies, telangiectatic lesions, dysostosis multiplex, characteristic magnetic resonance imaging finding along with undetectable levels of the fucosidase activity, which confirmed the diagnosis. Younger sibling has mild developmental delay with autistic traits with no neuroregression until now. He also has undetectable level of fucosidase enzyme activity and is being considered for stem cell transplantation. New case reports would expand the clinical spectrum, early diagnosis and help formulating appropriate therapy. Early diagnosis is crucial and hence sibling screening can be done, and those in the presymptomatic stage can undergo hematopoietic stem cell transplantation, which is potentially curable.

A Closer Look at Siblings of Patients with Schizophrenia: The Association of Depression History and Sex with Cognitive Phenotypes

2010-01-01

Background Siblings of patients with schizophrenia show impaired cognition and an increased prevalence of depression history. Although sex has been shown to moderate cognition in patients, this effect has not been examined in siblings. Here we elucidate how a history of depression and sex influences cognition in siblings unaffected by schizophrenia. Methods Unaffected siblings of patients with schizophrenia and unrelated healthy controls were evaluated neuropsychologically and completed structured clinical interviews. Participants with a depression history or no psychiatric history were selected for the sample. Cognitive performance of siblings (n = 366) and controls (n = 680) was first examined. Second, cognition of participants with a depression history and those without a psychiatric history was compared while additionally investigating the role of schizophrenia risk and sex. Results Relative to controls, siblings, with and without a psychiatric history, demonstrated significant (p < .05) cognitive deficits. Depression history impaired cognition in siblings, but not in controls; whereas sex affected cognition in both siblings and controls. In siblings alone, sex significantly interacted with depression history to influence cognition. This interaction revealed that in male - but not female - siblings a history of depression was associated with greater cognitive impairments. Conclusion A history of depression impairs cognition in siblings, but not in controls. Moreover, depression history interacts with sex and demonstrates that only cognition in male siblings is significantly and additionally compromised by a history of depression. This interaction may be an important consideration for future phenotype and genetic association studies. PMID:21030214

Despite recent focus on developing family-inclusive services to meet the needs of young people with first-episode psychosis, the needs of their siblings are often overlooked. This study explored the experiences and needs of siblings of young adults with first-episode psychosis receiving support from two Early Intervention in Psychosis Services in South-East England. Thirty-one siblings aged 11-35 years, were given a semi-structured interview to gather their perspectives and accounts of their lived experiences. The resultant rich qualitative data was analysed using responsive-reader and framework methods. Six themes were identified: siblings' roles and involvement; emotions; impact on relationships; coping patterns; resilience; and siblings' service needs. All participants had been greatly affected by the onset of the psychosis in their brother or sister. Most siblings did not identify themselves as carers, although most played a significant part in their brother's or sister's life. Participants wanted dynamic, robust and accessible services, especially information and peer support to meet their needs. © 2011 Blackwell Publishing Asia Pty Ltd.

This study, the first in Zambia using the Strange Situation Procedure (SSP) to observe attachment relationships and the "very first" observational study of infant-sibling attachment, examined patterns of infant-mother and infant-sibling attachment, and tested their association. We included siblings who were substantially involved in caregiving activities with their younger siblings. We hypothesized that infants would develop attachment relationships to both mothers and siblings; the majority of infants would be classified as securely attached to both caregivers, and infant-mother and infant-sibling attachment would be unrelated. The sample included 88 low-income families in Lusaka, Zambia (average of 3.5 children; SD = 1.5). The SSP distributions (infant-mother) were 59% secure, 24% avoidant and 17% resistant, and 46% secure, 20% avoidant, 5% resistant and 29% disorganized for three- and four-way classifications, respectively. The infant-sibling classifications were 42% secure, 23% avoidant and 35% resistant, and 35% secure, 23% avoidant, 9% resistant and 33% disorganized for three- and four-way classifications, respectively. Infant-mother and infant-sibling attachment relationships were not associated.

Siblings of Military Servicemembers: A Qualitative Exploration of Individual and Family Systems Reactions

Rodriguez, Aubrey J.; Margolin, Gayla

2012-01-01

How does having a sibling in the military affect young adults? Despite increasing attention to the challenges faced by spouses and children of servicemembers, the siblings of servicemembers have been largely ignored. This qualitative investigation uses unstructured narratives to explore siblings’ perceptions of changes in their lives and changes in the family of origin associated with having a family member enlist in the United States military. Thematic analyses revealed an acute period of conflict followed by reorganization, awareness of the parents’ distress, changes in the emotional climate of the family, shifts in family roles, admiration for the military sibling, and increased meaning and purpose for the family following the servicemember’s enlistment. Computer-assisted text analyses revealed both positive and negative emotional content associated with the siblings’ military service. For professional psychologists who come into contact with siblings of servicemembers, it is important to recognize that military enlistment can have ripple effects and complicate other common individual and family stresses. More generally, it is important to provide siblings and the family of origin with information about what to expect during and after the servicemember’s enlistment, especially since these families may lack support and contact from others going through similar transitions.

Sibling cannibalism in a web-building spider: effects of density and shared environment.

2014-07-01

Sibling cannibalism occurs across diverse taxa and can affect population size and structure, as well as the fitness of parents and the cannibal, via density effects and variation in individual propensity to cannibalize. We examined these effects on sibling cannibalism in juveniles of a web-building spider (Latrodectus hasselti, Australian redbacks). Adult redbacks are solitary, but juveniles live in clusters of variable density for a week after hatching. We confined newly hatched siblings from a singly-mated female to a low or high density treatment in a split-clutch design, then left spiderlings unfed for a week. Our results showed no effect of density on overall cannibalism levels, but a strong correlation between cannibalism counts from the same maternal lines across densities. Unlike web-bound sit-and-wait predators, wandering spiders that are active hunters have been shown to experience density-dependent cannibalism. In contrast, we suggest sibling cannibalism in web-building spiders may be density independent because early cohabitation on the web selects for elevated tolerance of conspecifics. We conclude that, rather than being linked to density, cannibalism of siblings in these species may be controlled more strongly by variation in individual propensity to cannibalize.

A recent study focusing on a response to antiepileptic drugs (AED) among siblings for epilepsy showed a similar response among epileptic siblings to specific AEDs or AED combinations. Currently, however, family history of treatment response to AEDs is not readily employed in deciding which initial medication to use when treating patients with epilepsy. We tested the hypothesis that sibling response to initial AED predicts treatment success. Presumed siblings were identified from a single-center database of patients diagnosed with epilepsy by matching last name, address, and name of parent(s). We identified 28 sibling pairs and two sibling trios with epilepsy. Seventeen of these sibling pairs were started on the same initial AED, with 15 sibling pairs having the same type of epilepsy. The remaining 11 pairs were started on a different initial AED, with 8 of these sibling pairs having the same type of epilepsy. Subjects with seizure freedom for a period of ≥1year were classified as a "responder". When at least one of the sibling pair responded to an initial AED, the proportion of the other siblings also responding to the initial AED was significantly higher if the siblings were treated with the same AED (8/11) compared to siblings who were treated with different AED (1/10) (Fisher's exact test, p-value=0.0075). These findings suggest that sibling response to initial AED is predictive of the success of AED therapy. This study is limited by a small cohort and retrospective design. Future, larger prospective studies are needed to reproduce and further validate these findings. Copyright © 2017. Published by Elsevier B.V.

An Adapted Measure of Sibling Attachment: Factor Structure and Internal Consistency of the Sibling Attachment Inventory in Youth.

2018-04-01

Parent-youth and peer relationship inventories based on attachment theory measure communication, trust, and alienation, yet sibling relationships have been overlooked. We developed the Sibling Attachment Inventory and evaluated its psychometric properties in a sample of 172 youth ages 10-14 years. We adapted the 25-item Sibling Attachment Inventory from the Inventory of Parent and Peer Attachment-Revised peer measure. Items loaded onto three factors, identified as communication, trust, and alienation, α = 0.93, 0.90, and 0.76, respectively. Sibling trust and alienation correlated with depression (r s  = -0.33, r s  = 0.48) and self-worth (r s  = 0.23; r s  = -0.32); sibling trust and alienation correlated with depression after controlling for parent trust and parent alienation (r s  = -0.23, r s  = 0.22). Preliminary analyses showed good internal consistency, construct validity, and incremental predictive validity. Following replication of these properties, this measure can facilitate large cohort assessments of sibling attachment.

To evaluate the impact of sodium benzoate and dextromethorphan treatment on patients with the attenuated form of nonketotic hyperglycinemia. Families were recruited with 2 siblings both affected with attenuated nonketotic hyperglycinemia. Genetic mutations were expressed to identify residual activity. The outcome on developmental progress and seizures was compared between the first child diagnosed and treated late with the second child diagnosed at birth and treated aggressively from the newborn period using dextromethorphan and benzoate at dosing sufficient to normalize plasma glycine levels. Both siblings were evaluated with similar standardized neurodevelopmental measures. In each sibling set, the second sibling treated from the neonatal period achieved earlier and more developmental milestones, and had a higher developmental quotient. In 3 of the 4 sibling pairs, the younger sibling had no seizures whereas the first child had a seizure disorder. The adaptive behavior subdomains of socialization and daily living skills improved more than motor skills and communication. Early treatment with dextromethorphan and sodium benzoate sufficient to normalize plasma glycine levels is effective at improving outcome if used in children with attenuated disease with mutations providing residual activity and when started from the neonatal period.

Sibling self-management: Programming for generalization to improve interactions between typically developing siblings and children with autism spectrum disorders.

PubMed

Kryzak, Lauren A; Jones, Emily A

2017-11-01

The present study taught typically developing (TD) siblings of children with autism spectrum disorders (ASD) social-communicative and self-management skills. The authors' hypothesized that the acquisition of self-management skills would support generalization of targeted social-communicative responses. A multiple baseline probe design across sibling dyads was used to decrease exposure to unnecessary sessions in the absence of intervention. Four TD siblings were taught self-management of a social skills curriculum using behavioral skills training, which consisted of instructions, modeling, practice, and subsequent feedback. Results indicated that TD siblings learned to self-manage the social skills curriculum with some generalization across novel settings and over time. Comparisons of social-communicative responses to their typical peers provided some support for the social validity of the intervention outcomes. These results support the use of self-management, when explicitly programming for generalization, which continues to be a key consideration when including TD siblings in interventions with their siblings with ASD.

Sibship size, sibling cognitive sensitivity, and children's receptive vocabulary.

2014-02-01

The aim of the current study was to examine the relationship between sibship size and children's vocabulary as a function of quality of sibling interactions. It was hypothesized that coming from a larger sibship (ie, 3+ children) would be related to lower receptive vocabulary in children. However, we expected this association to be moderated by the level of cognitive sensitivity shown by children's next-in-age older siblings. Data on 385 children (mean age = 3.15 years) and their next-in-age older siblings (mean age = 5.57 years) were collected and included demographic questionnaires, direct testing of children's receptive vocabulary, and videos of mother-child and sibling interactions. Sibling dyads were taped engaging in a cooperative building task and tapes were coded for the amount of cognitive sensitivity the older sibling exhibited toward the younger sibling. Hierarchical regression analyses were conducted and showed an interaction between sibship size and sibling cognitive sensitivity in the prediction of children's receptive vocabulary; children exposed to large sibships whose next-in-age older sibling exhibited higher levels of cognitive sensitivity were less likely to show low vocabulary skills when compared with those children exposed to large sibships whose siblings showed lower levels of cognitive sensitivity. Children who show sensitivity to the cognitive needs of their younger siblings provide a rich environment for language development. The negative impact of large sibships on language development is moderated by the presence of an older sibling who shows high cognitive sensitivity.

Gaab, Erin M; Owens, Glynn R; MacLeod, Roderick D

2014-01-01

The experiences of young people who have siblings with life-limiting illnesses are not well understood. The study proposed to identify the concerns of siblings of pediatric palliative care (PPC) patients. Semistructured interviews were administered to participants and analyzed using qualitative inductive thematic analysis. Study subjects were 18 siblings of PPC patients aged 9 to 22 living in the Auckland area. The siblings of PPC patients held concerns about their siblings' impending death and desires to be involved in their lives and care. Siblings may benefit from opportunities to be involved in conversations about mortality and the care of their ill sibling. They are able to express their concerns and help provide care to PPC patients.

Joint Attention Initiation with and without Positive Affect: Risk Group Differences and Associations with ASD Symptoms

PubMed Central

Gangi, Devon N.; Ibañez, Lisa V.; Messinger, Daniel S.

2014-01-01

Infants at risk for Autism Spectrum Disorders (ASD) may have difficulty integrating smiles into initiating joint attention (IJA) bids. A specific IJA pattern, anticipatory smiling, may communicate preexisting positive affect when an infant smiles at an object and then turns the smile toward the social partner. We compared the development of anticipatory smiling at 8, 10, and 12 months in infant siblings of children with ASD (high-risk siblings) and without ASD (low-risk siblings). High-risk siblings produced less anticipatory smiling than low-risk siblings, suggesting early differences in communicating preexisting positive affect. While early anticipatory smiling distinguished the risk groups, IJA not accompanied by smiling best predicted later severity of ASD-related behavioral characteristics among high-risk siblings. High-risk infants appear to show lower levels of motivation to share positive affect with others. However, facility with initiating joint attention in the absence of a clear index of positive affective motivation appears to be central to the prediction of ASD symptoms. PMID:24281421

Investigating the impact of Angelman syndrome on the sibling relationship. This study explored differences in sibling relationships between children with a typically-developing sibling (n = 55) and children with a sibling with Angelman syndrome (n = 44). Sibling relationships were compared on four factors and 16 sub-scales of the Sibling Relationship Questionnaire-Revised. Results showed significant differences in mean scores on each of the four factors (i.e. Warmth/Closeness, Conflict, Rivalry and Dominance/Nurturance) and most of the sub-scales. ANCOVAs showed that demographic variables (number of siblings, living in a two-parent vs single parent household, gender, participant's age, place of residence) did not influence significant differences in sibling relationships between the two groups. Having a brother or sister with Angelman syndrome may influence the way in which the sibling perceives the sibling relationship. This may have important implications for family-centred intervention for this population.

2012-01-01

Although socioemotional competencies have been identified as key components of youths’ positive development, most studies on empathy are cross-sectional, and research on the role of the family has focused almost exclusively on parental socialization. This study examined the developmental course of empathy from age 7 to 14 and the within-person associations between sibling warmth and conflict and youths’ empathy. On three occasions across 2 years, mothers, fathers, and the two eldest siblings from 201 White, working- and middle-class families provided questionnaire data. Multilevel models revealed that, controlling for youths’ pubertal status and parental education, girls’ empathy increased during the transition to adolescence and then leveled off, but boys’ lower levels of empathy remained relatively unchanged. Moreover, controlling for parental responsiveness and marital love, at times when firstborns and second-borns reported more sibling warmth and less sibling conflict than usual, they also reported more empathy than usual. The within-person association between sibling warmth and empathy also became stronger over time. Findings highlight gender differences in empathy development and the unique role of siblings in shaping each other’s socioemotional characteristics during adolescence. PMID:22714744

To characterize visual function in defined genotypes including siblings with Usher syndrome. Thirteen patients with phenotypically different subtypes of Usher syndrome, including 3 families with affected siblings, were selected. Genetic analysis and ophthalmological examinations including visual fields, full-field electroretinography (ERG), multifocal electroretinography (mf ERG), and optical coherence tomography (OCT) were assessed. The patients' degree of visual handicap was evaluated by a questionnaire (ADL). Twelve of thirteen patients were genotyped as Usher 1B, 1D, 1F, 2A, 2C or 3A. In 12 of 13 patients examined with ERG the 30 Hz flickering light response revealed remaining cone function. In 3 of the patients with Usher type 1 mf ERG demonstrated a specific pattern, with a sharp distinction between the area with reduced function and the central area with remaining macular function and normal peak time. OCT demonstrated loss of foveal depression with distortion of the foveal architecture in the macula in all patients. The foveal thickness ranged from 159 to 384 µm and was not correlated to retinal function. Three siblings shared the same mutation for Usher 2C but in contrast to previous reports regarding this genotype, 1 of them diverged in phenotype with substantially normal visual fields, almost normal OCT and mf ERG findings, and only moderately reduced rod and cone function according to ERG. Evaluation of visual function comprising both the severity of the rod cone degeneration and the function in the macular region confirm phenotypical heterogeneity within siblings and between different genotypes of Usher syndrome.

Siblings of children with disabilities: research themes.

PubMed

Stoneman, Zolinda

2005-10-01

Until the early 1980s, most researchers paid little attention to sibling relationships. Studies of mothers dominated the research agenda, to the almost total exclusion of fathers, extended families, and siblings. Although in early classic studies of families of children with disabilities, investigators embraced a family systems approach that included siblings, this emphasis did not take root until recently. There has been an impressive growth in the number of published studies focusing on siblings of children with disabilities. In this paper, my goal is to examine themes in this research and reflect on our state of knowledge.

Sibling Relationships and Influences in Childhood and Adolescence

PubMed Central

McHale, Susan M.; Updegraff, Kimberly A.; Whiteman, Shawn D.

2014-01-01

The authors review the literature on sibling relationships in childhood and adolescence, starting by tracing themes from foundational research and theory and then focusing on empirical research during the past 2 decades. This literature documents siblings’ centrality in family life, sources of variation in sibling relationship qualities, and the significance of siblings for child and adolescent development and adjustment. Sibling influences emerge not only in the context of siblings’ frequent and often emotionally intense interactions but also by virtue of siblings’ role in larger family system dynamics. Although siblings are building blocks of family structure and key players in family dynamics, their role has been relatively neglected by family scholars and by those who study close relationships. Incorporating study of siblings into family research provides novel insights into the operation of families as social and socializing systems. PMID:24653527

The objectives of this review are to highlight the impact of the first decade of high-risk (HR) infant sibling work in autism spectrum disorder (ASD) and to identify potential areas of translational focus for the next decade of research. A group of clinicians and researchers in ASD working both inside and outside of the HR design met on a regular basis to review the infant sibling research, and came to an agreement on areas that had changed clinical practice and areas that had the potential to change practice with further research. The group then outlined several methodological and translational challenges that must be addressed in the next decade of research if the field is to reach its potential. The review concluded that the HR design has yielded an understanding that ASD often, but not always, begins to emerge between 6 and 18 months, with early signs affecting social communication. Research using the HR design has also allowed a better understanding of the sibling recurrence risk (between 10% and 20%). Emerging areas of interest include the developmental trajectories of social communications skills in the early years, the expression of a milder phenotype in siblings not affected with ASD, and the possibility that early intervention with infant siblings may improve outcomes for those with ASD. Important challenges for the future include linking screening to intervention, collecting large sample sizes while ensuring cross-site reliability, and building in capacity for replication. Although there are significant methodological and translational challenges for high-risk infant sibling research, the potential of this design to improve long-term outcomes of all children with ASD is substantial.

Equine recurrent uveitis (ERU) is a common cause of ocular pain and blindness in horses. Leptospira spp. have been commonly implicated in the pathophysiology of ERU in mainland Europe and the USA. No recent studies have been carried out in the UK, but Leptospira is reported not to be a major factor in the aetiology of ERU in the UK. To establish the prevalence of Leptospira-associated ERU in the UK and to identify the serovars involved in these cases; to compare serum vs. aqueous humour antibody levels in cases and controls in order to confirm the diagnosis of Leptospira-associated ERU, and to assess the usefulness of serology alone as a confirmatory test for Leptospira-associated ERU in the UK. Case-control study. Eyes enucleated for clinical reasons in ERU-affected horses were collected. Blood and aqueous humour were obtained to determine antibody levels against a variety of Leptospira serovars and C-values (aqueous humour value/serum value) were calculated. In addition, eyes, blood and aqueous humour were obtained from control cases for comparison. Histopathology was performed in all eyes to confirm uveitis in each case. Differences in seroprevalences between ERU and control cases and between Leptospira- and non-Leptospira-associated ERU cases were calculated. A total of 30 ERU and 43 control eyes were analysed. Of the ERU eyes, only two had a C-value of >4 (prevalence of Leptospira-associated uveitis: 6.7%). Serovars hardjo and javanica were detected. There was no difference in seroprevalence between horses with uveitis and control cases (65.5% and 41.9%, respectively; P = 0.11) or between Leptospira- and non-Leptospira-associated uveitis cases (100% and 63.0%, respectively; P = 0.52). The study was limited by low case numbers. Eyes were presented at different stages of disease. The only test used to detect Leptospira was the microscopic agglutination test. Leptospira-associated ERU is uncommon in the UK. Serology alone may not help to definitively diagnose

Familial risk and sibling mentalization: Links with preschoolers' internalizing problems.

2017-09-01

The current study explored whether older sibling mentalization moderated the relationship between familial risk for internalizing symptoms and the development of future internalizing problems in the younger siblings, referred to as target children. Data were collected on 397 older siblings at Time 1 (T1) when target children were newborn and their older siblings were on average 2.61 years old (SD = .75). Target children were on average 1.60 years old at Time 2 (T2). Internalizing problems were assessed via mother and partner reports. Familial risk was operationalized as the average of all older siblings' level of internalizing problems. Older sibling mentalization, indexed by internal state talk and reasoning, was observed and coded during a sibling pretend-play interaction at T2. Results revealed a significant interaction between familial risk of internalizing problems and older siblings' mentalizing abilities, showing that familial risk was related to target children's internalizing problems in the absence of sibling mentalization. Familial risk was not associated with target children's internalizing problems when siblings demonstrated mentalizing abilities. Findings support the need to consider sibling mentalization as a protective factor for children's internalizing problems. (PsycINFO Database Record (c) 2017 APA, all rights reserved).

Capturing the Temporal Sequence of Interaction in Young Siblings

2015-01-01

We explored whether young children exhibit subtypes of behavioral sequences during sibling interaction. Ten-minute, free-play observations of over 300 sibling dyads were coded for positivity, negativity and disengagement. The data were analyzed using growth mixture modeling (GMM). Younger (18-month-old) children’s temporal behavioral sequences showed a harmonious (53%) and a casual (47%) class. Older (approximately four-year-old) children’s behavior was more differentiated revealing a harmonious (25%), a deteriorating (31%), a recovery (22%) and a casual (22%) class. A more positive maternal affective climate was associated with more positive patterns. Siblings’ sequential behavioral patterns tended to be complementary rather than reciprocal in nature. The study illustrates a novel use of GMM and makes a theoretical contribution by showing that young children exhibit distinct types of temporal behavioral sequences that are related to parenting processes.

Despite rigorous research on disturbances of executive function and social cognition in autism spectrum disorders (ASD), little information has been available concerning higher cognitive functions, such as the ability to focus and associate relevant features to form categories, or 'organizing of information'. The purpose of this study was to investigate this issue by using the Wisconsin Card Sorting Test (WCST) and the Verbal Learning Task (VLT). Cognitive assessments were conducted in 22 individuals with ASD, 14 non-affected siblings, and 15 age-matched control subjects. Overall, individuals with ASD performed significantly worse on the WCST and VLT compared to their siblings and normal control subjects. Although siblings performed generally well on both tasks, they exhibited similar degree of perseverative responses in the WCST compared to the probands. A linear increase of the memory organization score in the VLT was also absent in siblings as well as the ASD group. These results suggest an impaired ability to organize information is one of the cognitive endophenotypes for ASD. Copyright © 2010 Elsevier Ireland Ltd and the Japan Neuroscience Society.

PubMed

Seiffge-Krenke, I

2001-01-01

Although sibling relationships can be considered as one of the most durable and intensive relationships, not much research in developmental psychology and family research has been done on this issue. The strong focus on parents, more specifically on mothers, stood in the way of adequate conceptualization and understanding of the function and contribution of siblings to individual development and family interaction. In this contribution a conceptualization of sibling relationships is presented. Siblings as objects of aggressive and sexual feelings as well as the function of siblings in the family system, for example, as parentification and negative identity is emphasized. In addition, the different qualities of sibling relationships, for example, envy, rivalry, similarity, and difference, are emphasized. The function of siblings as love objects is stressed, and the role of siblings as support as well as teaching object is illustrated. Finally, it is emphasized that, similar to relationships between parents and child, the quality of sibling relationships changed over time and leads, for example, to a detachment between sibling relationships during adolescence.

Food reinforcement and delay discounting in zBMI-discordant siblings.

2015-02-01

The interaction of food reinforcement and the inability to delay gratification are related to adult energy intake and obesity. This study was designed to test the association of sibling pair differences in relative reinforcing efficacy of food and delay discounting on sibling pair differences in zBMI scores of same-gender zBMI-discordant siblings. We tested main and interactive relationships between delay discounting and relative reinforcing efficacy of food on zBMI discordance in 14 zBMI-discordant biological sibling pairs (6 female pairs) using a discordant sibling study design. Sibling pair differences in relative reinforcing efficacy of food were associated with sibling pair differences in zBMI (p= 0.046); this effect was moderated by delay discounting (p <0.002). Sibling pairs with greater differences in relative reinforcing efficacy and delay discounting had greater differences in zBMI. The combination of greater sibling pair differences in delay discounting and relative reinforcing efficacy is associated with greater discordance in zBMI in adolescent sibling pairs.

Dysfunctional response inhibition is a key executive function impairment in attention deficit hyperactivity disorder (ADHD). Still, behavioral response inhibition measures do not consistently differentiate affected from unaffected individuals. The authors therefore investigated neural correlates of response inhibition and the familial nature of these neural correlates. Functional MRI measurements of neural activation during the stop-signal task and behavioral measures of response inhibition were obtained in adolescents and young adults with ADHD (N=185), their unaffected siblings (N=111), and healthy comparison subjects (N=124). Stop-signal task reaction times were longer and error rates were higher in participants with ADHD, but not in their unaffected siblings, while reaction time variability was higher in both groups than in comparison subjects. Relative to comparison subjects, participants with ADHD and unaffected siblings had neural hypoactivation in frontal-striatal and frontal-parietal networks, whereby activation in inferior frontal and temporal/parietal nodes in unaffected siblings was intermediate between levels of participants with ADHD and comparison subjects. Furthermore, neural activation in inferior frontal nodes correlated with stop-signal reaction times, and activation in both inferior frontal and temporal/parietal nodes correlated with ADHD severity. Neural activation alterations in ADHD are more robust than behavioral response inhibition deficits and explain variance in response inhibition and ADHD severity. Although only affected participants with ADHD have deficient response inhibition, hypoactivation in inferior frontal and temporal-parietal nodes in unaffected siblings supports the familial nature of the underlying neural process. Activation deficits in these nodes may be useful as endophenotypes that extend beyond the affected individuals in the family.

Penguin chicks benefit from elevated yolk androgen levels under sibling competition.

Crested penguins (genus Eudyptes) have a peculiar hatching pattern, with the first-laid egg (A-egg) hatching after the second-laid egg (B-egg) and chicks from A-eggs typically having a much lower survival probability. Maternal yolk androgens have been suggested to contribute to the competitive superiority of the B-chick in southern rockhopper penguins Eudyptes chrysocome, given their important role in mediating sibling competition in other species. We therefore increased the yolk androgen levels in freshly-laid eggs and examined the consequences for sibling competition--via effects on embryonic developmental times, chick growth and early survival. We placed one androgen-treated egg and one control egg into each foster nest, matching them for mass, laying date and laying order. The androgen treatment did not significantly affect embryonic developmental times or chick measurements at hatching. However, elevated yolk androgen levels benefitted chick growth in interaction with the number of siblings in a brood. Chicks from androgen-treated eggs had faster growth in the presence of a sibling than chicks from control eggs. Under these circumstances they also had a higher survival probability. Thus maternal androgens appear to reinforce the observed hatching pattern, facilitating brood reduction. This contrasts to most previous studies in other species where yolk androgens have been shown to compensate for the negative consequences of delayed hatching within the brood hierarchy.

2002-01-01

Background Family history and twins studies suggest an inherited component to ischemic stroke risk. Candidate gene association studies have been performed but have limited capacity to identify novel risk factor genes. The Siblings With Ischemic Stroke Study (SWISS) aims to conduct a genome-wide scan in sibling pairs concordant or discordant for ischemic stroke to identify novel genetic risk factors through linkage analysis. Methods Screening at multiple clinical centers identifies patients (probands) with radiographically confirmed ischemic stroke and a family history of at least 1 living full sibling with stroke. After giving informed consent, without violating privacy among other family members, the proband invites siblings concordant and discordant for stroke to participate. Siblings then contact the study coordinating center. The diagnosis of ischemic stroke in potentially concordant siblings is confirmed by systematic centralized review of medical records. The stroke-free status of potentially discordant siblings is confirmed by validated structured telephone interview. Blood samples for DNA analysis are taken from concordant sibling pairs and, if applicable, from 1 discordant sibling. Epstein-Barr virus-transformed lymphoblastoid cell lines are created, and a scan of the human genome is planned. Discussion Conducting adequately powered genomics studies of stroke in humans is challenging because of the heterogeneity of the stroke phenotype and the difficulty of obtaining DNA samples from clinically well-characterized members of a cohort of stroke pedigrees. The multicentered design of this study is intended to efficiently assemble a cohort of ischemic stroke pedigrees without invoking community consent or using cold-calling of pedigree members.

The ways in which middle-childhood siblings perceive themselves as similar or different was assessed with a sample of 40 pairs of 9- to 11-year-old (younger) and 12- to 14-year-old (older) siblings. Each child was interviewed and completed a card sort procedure and a measure of self-competence. Sibling pairs participated in three behavioral tasks coded for cooperation and conflict. Self-ratings, self-perceptions, and sibling behavior were analyzed for their association with the perceived similarity construct. Siblings perceived themselves as being more like one another than did their mothers. Forty-one percent of the variance in their perceived similarity was accounted for by paired self-cooperation ratings, social competence, and behavioral task scores.

The purpose of this study was to explore the experiences of siblings of individuals with autism spectrum disorders (ASDs) and identify their self-reported support needs. We conducted in-person semi-structured interviews with 12 siblings aged 7 to 15 of children aged 6 to 15 with ASDs. Employing a qualitative collective case study research method, we conducted cross-case analyses to address our research questions. Three major themes emerged: (a) descriptions of the sibling subsystem (b) cohesion between and among the siblings, and (c) adaptability of the participant siblings to having family members with ASDs. Discussion of these findings and recommendations for future research contributes to the existing literature on siblings of children with disabilities. PMID:22928104

Attrition in Models of Intergenerational Links Using the PSID with Extensions to Health and to Sibling Models*

PubMed Central

Fitzgerald, John M.

2012-01-01

Selective attrition potentially biases estimation of intergenerational links in health and economic status. This paper documents attrition in the PSID through 2007 for a cohort of children, and investigates attrition bias in intergenerational models predicting adult health, education and earnings, including models based on sibling differences. Although attrition affects unconditional means, the weighted PSID generally maintains its representativeness along key dimensions in comparison to the National Health Interview Survey. Using PSID, sibling correlations in outcomes and father-son correlations in earnings are not significantly affected by attrition. Models of intergenerational links with covariates yield more mixed results with females showing few robust impacts of attrition and males showing potential attrition bias for education and earnings outcomes. For adult health outcomes conditional on child background, neither gender shows significant impacts of attrition for the age ranges and models considered here. Sibling models do not produce robustly higher attrition impacts than individual models. PMID:22368743

Aggression between siblings: Associations with the home environment and peer bullying.

2015-01-01

Sibling aggression is a common form of intra-familial aggression, yet has been largely neglected by research. Using an inclusive measure of sibling aggression, this study investigated, firstly, prevalence of sibling aggression and associations with family and household characteristics, and secondly, the relationship between sibling aggression and peer bullying. Participants were 4,237 adolescents from Wave 1 of Understanding Society. Four types of sibling aggression were measured: physical, verbal, stealing and teasing, and combined into composite measures of victimization and perpetration. Regression analysis identified associations with demographic characteristics, family and sibling composition, parent-child relationships and socioeconomic status and explored the link between sibling aggression and involvement in peer bullying. Using a broad definition, sibling aggression was found to be widespread, with 46% of all participants being victimized and 36% perpetrating aggression. Household and family characteristics, including a large family size, male siblings, and financial difficulties were associated with greater rates of sibling aggression. Parenting behavior showed the strongest relationship: harsh parenting increased the risk of sibling aggression while positive parenting protected against it. Sibling aggression was also homotypically related to involvement in peer bullying. Victimization by siblings significantly increased the odds of being a victim of peer bullying, and perpetrators of sibling aggression were more likely to be both peer bullies and bully-victims. Considering the adverse effects of sibling aggression on physical and mental health, the study provides pointers for efforts to reduce the risk of sibling aggression. Furthermore, the link with peer bullying suggests that school anti-bullying efforts should also take account of children's sibling relationships. Aggr.

GROWING UP WITHOUT SIBLINGS AND ADULT SOCIABILITY BEHAVIORS

PubMed Central

Trent, Katherine; Spitze, Glenna D.

2011-01-01

We use data from the National Survey of Families and Households to examine a range of sociability behaviors for adults who grew up with and without siblings. Compared to adults who grew up with siblings, adults who grew up without siblings have less frequent social activities with relatives, and the difference is greater among those who did not live with both parents growing up. Differences in engaging in certain social events between adults who grew up without and with siblings vary by age. Differences in participation in sports, youth, or school related group activities for those who grew up without and with siblings vary by gender. Thus, there are some differences in adult sociability behaviors between those who grew up with and without siblings; however, our pattern of findings suggests that these differences are not large or pervasive across a range of sociability behaviors and may grow smaller with age.

Sibling recognition and the development of identity: intersubjective consequences of sibling differentiation in the sister relationship.

PubMed

Vivona, Jeanine M

2013-01-01

Identity is, among other things, a means to adapt to the others around whom one must fit. Psychoanalytic theory has highlighted ways in which the child fits in by emulating important others, especially through identification. Alternately, the child may fit into the family and around important others through differentiation, an unconscious process that involves developing or accentuating qualities and desires in oneself that are expressly different from the perceived qualities of another person and simultaneously suppressing qualities and desires that are perceived as similar. With two clinical vignettes centered on the sister relationship, the author demonstrates that recognition of identity differences that result from sibling differentiation carries special significance in the sibling relationship and simultaneously poses particular intersubjective challenges. To the extent that the spotlight of sibling recognition delimits the lateral space one may occupy, repeatedly frustrated desires for sibling recognition may have enduring consequences for one's sense of self-worth and expectations of relationships with peers and partners.

Given previous evidence of familial predisposition for longevity, we hypothesized that siblings and parents of supercentenarians (age >or= 110 years) were predisposed to survival to very old age and that, relative to their birth cohorts, their relative survival probabilities (RSPs) are even higher than what has been observed for the siblings of centenarians. Mean age at death conditional upon survival to ages 20 and 50 and survival probabilities from ages 20 and 50 to higher ages were determined for 50 male and 56 female siblings and 54 parents of 29 supercentenarians. These estimates were contrasted with comparable estimates based on birth cohort-specific mortality experience for the United States and Sweden. Conditional on survival to age 20 years, mean age at death of supercentenarians' siblings was approximately 81 years for men and women. Compared with respective Swedish and U.S. birth cohorts, these estimates were 17%-20% (12-14 years) higher for the brothers and 11%-14% (8-10 years) higher for the sisters. Sisters had a 2.9 times greater probability and brothers had a 4.3 times greater probability of survival from age 20 to age 90. Mothers of supercentenarians had a 5.8 times greater probability of surviving from age 50 to age 90. Fathers also experienced an increased survival probability from age 50 to age 90 of 2.7, but it failed to attain statistical significance. The RSPs of siblings and mothers of supercentenarians revealed a substantial survival advantage and were most pronounced at the oldest ages. The RSP to age 90 for siblings of supercentenarians was approximately the same as that reported for siblings of centenarians. It is possible that greater RSPs are observed for reaching even higher ages such as 100 years, but a larger sample of supercentenarians and their siblings and parents is needed to investigate this possibility.

Korean Sibling Caregivers of Individuals Diagnosed with Schizophrenia

PubMed Central

Park, Mijung; Lee, Kwang-Ja

2018-01-01

Siblings of individuals diagnosed with schizophrenia are an important source of family caregiving. Unfortunately, limited information is available about sibling caregivers because existing studies have focused on other family relationships such as parents, spouses, and children. To fill the knowledge gap, the purpose of this study is to describe Korean sibling caregivers’ experience with individuals diagnosed with schizophrenia. Guided by Colaizzi’s descriptive phenomenological methodology, we conducted in-depth, semi-structured, face-to-face interviews with eight individuals who have a sibling (1) diagnosed with schizophrenia and (2) hospitalized in an inpatient psychiatric unit. We discerned six key themes: sorrow, burnout, shame, different perspectives in life, acceptance, and responsibility. We categorized these themes into three groups: suffering, hope, and responsibility and obligation. Sibling caregivers of individuals with schizophrenia experience a mixture of several emotions. Participants loved their brother or sister with schizophrenia, but at the same time they felt shame and fear. While they were burdened by the responsibilities of caregiving, they remained loyal to their sibling with schizophrenia, continuing to help their siblings reach their full potential. Although participants were confused about the symptoms of schizophrenia, they were committed to learning more about the illness. Because we conducted the current study in Korea, the findings of this study may be unique to Korea culture. Further studies are needed to compare and contrast nuanced differences in sibling caregivers’ experience among different cultural groups. PMID:29376114

To study the clinical and genetic characteristics of twins and siblings affected with Wilson's disease (WD). Clinical data and blood samples were collected from the subjects after informed consent was obtained. Genomic DNA was extracted and potential mutations in the exons in ATP7B gene were detected with PCR-DNA sequencing. Short tandem repeat (STR) genotyping was performed to determine the zygosity of the twins. The 5 pairs of twins have all met the diagnostic criteria for WD. STR genotyping has confirmed that 4 pairs were monozygotic twins. 3 pairs of twins had an onset with liver symptoms, the other 2 had an onset with brain symptoms. ATP7B gene mutations were detected in 4 pairs of twins, which have all located in exons 8 and 13. A heterozygous p.R778W mutation in exon 8 and homozygous p.P992L mutation in exon 13 were detected in all patients from one family, whose parents have carried a heterozygous p.R778W mutation and p.P992L heterozygous mutation, respectively, which suggested loss of heterozygosity (LOH). In one family, no mutation was detected in all exons of the ATP7B gene in the patients and their parents. For a triplet, one female was with definite WD and brain symptoms at the onset, one male had subclinical type with WD, whilst another female was completely normal. The triplets and their mother have all carried a p.P992L heterozygous mutation . Above results have confirmed an important role for genetic factors in the pathogenesis of WD. In addition to point mutations, LOH is also involved in the pathogenesis for WD.

Forgotten family members: the importance of siblings in early psychosis.

Bowman, Siann; Alvarez-Jimenez, Mario; Wade, Darryl; McGorry, Patrick; Howie, Linsey

2014-08-01

This paper reviews the evidence on the significance of sibling inclusion in family interventions and support during early psychosis. This narrative review presents the current research related to the importance of family work during early psychosis, the needs and developmental significance of siblings during adolescence and early adulthood, the protective effects of sibling relationships, and the characteristics of early psychosis relevant to the sibling experience. It will also review the evidence of the sibling experience in chronic physical illness and disability, as well as long-term psychotic illness. Despite the evidence that working with families is important during early psychosis, siblings have been largely ignored. Siblings are an important reciprocal relationship of long duration. They play an important role in development during adolescence and early adulthood. These relationships may be an underutilized protective factor due to their inherent benefits and social support. Developmental theories imply that early psychosis could negatively impact the sibling relationship and their quality of life, effecting personality development and health outcomes. The evidence shows that adolescent physical illness or disability has a significantly negative impact on the sibling's quality of life and increases the risk for the onset of mental health issues. Long-term psychotic illness also results in negative experiences for siblings. Current evidence shows that siblings in early psychosis experience psychological distress and changes in functional performance. Further research using standard measures is required to understand the impact early psychosis has on the sibling relationship and their quality of life. © 2013 Wiley Publishing Asia Pty Ltd.

Profiles of executive function in parents and siblings of individuals with autism spectrum disorders.

Wong, D; Maybery, M; Bishop, D V M; Maley, A; Hallmayer, J

2006-11-01

Delineation of a cognitive endophenotype for autism is useful both for exploring the genetic mechanisms underlying the disorder and for identifying which cognitive traits may be primary to it. This study investigated whether first-degree relatives of individuals with autism spectrum disorders (ASDs) demonstrate a specific profile of performance on a range of components of executive function (EF), to determine whether EF deficits represent possible endophenotypes for autism. Parents and siblings of ASD and control probands were tested on EF tasks measuring planning, set-shifting, inhibition and generativity. ASD parents showed poorer performance than control parents on a test of ideational fluency or generativity, and ASD fathers demonstrated a weakness in set-shifting to a previously irrelevant dimension. ASD siblings revealed a mild reduction in ideational fluency and a weakness in non-verbal generativity when compared with control siblings. Neither ASD parents nor siblings displayed significant difficulties with planning or inhibition. These results indicated that the broad autism phenotype may not be characterized primarily by impairments in planning and cognitive flexibility, as had been previously proposed. Weaknesses in generativity emerged as stronger potential endophenotypes in this study, suggesting that this aspect of EF should play a central role in cognitive theories of autism. However, discrepancies in the EF profile demonstrated by parents and siblings suggest that factors related to age or parental responsibility may affect the precise pattern of deficits observed.

Sibling cooperation in earwig families provides insights into the early evolution of social life.

Falk, Joachim; Wong, Janine W Y; Kölliker, Mathias; Meunier, Joël

2014-04-01

The evolutionary transition from solitary to social life is driven by direct and indirect fitness benefits of social interactions. Understanding the conditions promoting the early evolution of social life therefore requires identification of these benefits in nonderived social systems, such as animal families where offspring are mobile and able to disperse and will survive independently. Family life is well known to provide benefits to offspring through parental care, but research on sibling interactions generally focused on fitness costs to offspring due to competitive behaviors. Here we show experimentally that sibling interactions also reflect cooperative behaviors in the form of food sharing in nonderived families of the European earwig, Forficula auricularia. Food ingested by individual offspring was transferred to their siblings through mouth-to-anus contacts and active allo-coprophagy. These transfers occurred in both the presence and the absence of the tending mothers, even though the direct contact with the mothers limited sibling food sharing. Neither food deprivation or relatedness influenced the total amount of transferred food, but relatedness affected frass release and the behavioral mechanisms mediating food sharing. Related offspring obtained food predominately through allo-coprophagy, whereas unrelated offspring obtained food through mouth-to-anus contacts. Overall, this study emphasizes that sibling cooperation may be a key process promoting the early evolution of social life.

2016-11-01

Anorexia nervosa (AN) is often first diagnosed in the adolescent years. The treatment with the greatest evidence during this time is family-based treatment (FBT). In FBT, siblings are expected to attend treatment sessions; however, sibling well-being during this time has not been well researched. This study aimed to explore sibling well-being when the ill child was initially diagnosed with AN and after FBT had been completed. Eighty-five parents and 55 siblings of adolescents with AN completed the Strengths and Difficulties Questionnaire at diagnosis. In addition, 88 parents and 46 siblings completed the Strengths and Difficulties Questionnaire after finishing treatment. Mothers and fathers reported siblings to have lower levels of conduct problems in comparison with population norms. Mothers also reported lower levels of prosocial behaviours. Siblings reported higher levels of emotional difficulties and hyperactivity in comparison with their peers. There were no differences in reported psychosocial well-being of siblings between diagnosis and following FBT. Siblings of adolescents with AN have poorer psychosocial adjustment than their peers, both before and after FBT. Clinicians and parents are encouraged to be aware of sibling difficulties and seek additional support if required. Copyright © 2016 John Wiley & Sons, Ltd and Eating Disorders Association.

Patterns of adjustment among siblings exposed to intimate partner violence.

Piotrowski, Caroline C

2011-02-01

This research explored and compared patterns of adjustment in siblings exposed to intimate partner violence. The quality of family relationships were investigated as potential mechanisms that accounted for heterogeneity in these patterns. Participants included 47 sibling pairs and their mothers recruited from the community. Mothers and children reported on child adjustment measures and the quality of family relationships. Five cluster patterns were identified for both younger and older siblings, replicating three identified in previous research: primarily internalizing symptoms, a combination of internalizing and externalizing symptoms, and an asymptomatic cluster. There was little overlap in cluster membership within families; most siblings differed in terms of their pattern of adjustment. The quality of family relationships varied significantly across clusters. Overall, asymptomatic siblings reported the most positive family relationships. Maternal warmth differed across clusters for both older and younger siblings, while maternal hostility varied across clusters for older but not younger siblings. The quality of sibling relationships also differed across clusters for older but not younger siblings. These findings underscore the importance of examining differential sibling experiences within violent families, and demonstrate the significance of family relationships as a mediating mechanism influencing heterogeneous child adjustment.

Sibling genes as environment: Sibling dopamine genotypes and adolescent health support frequency dependent selection.

PubMed

Rauscher, Emily; Conley, Dalton; Siegal, Mark L

2015-11-01

While research consistently suggests siblings matter for individual outcomes, it remains unclear why. At the same time, studies of genetic effects on health typically correlate variants of a gene with the average level of behavioral or health measures, ignoring more complicated genetic dynamics. Using National Longitudinal Study of Adolescent Health data, we investigate whether sibling genes moderate individual genetic expression. We compare twin variation in health-related absences and self-rated health by genetic differences at three locations related to dopamine regulation and transport to test sibship-level cross-person gene-gene interactions. Results suggest effects of variation at these genetic locations are moderated by sibling genes. Although the mechanism remains unclear, this evidence is consistent with frequency dependent selection and suggests much genetic research may violate the stable unit treatment value assumption.

Genetic influence on age at first birth of female twins born in the UK, 1919-68.

2015-01-01

Using a sample of monozygotic (945, 42 per cent) and dizygotic (1,329, 58 per cent) twin pairs born 1919-68 in the UK, we applied innovative tobit models to investigate genetic and environmental influences on age at first birth (AFB). We found that a substantial part (40 per cent) of the variation in AFB is caused by latent family characteristics. Genetic dispositions (26 per cent) play a more important role than the shared environment of siblings (14 per cent), with the non-shared environment/measurement error having the strongest influence (60 per cent). Like previous studies, this study reveals marked changes in estimates over time, and supports the idea that environmental constraints (war or economic crisis) suppress and normative freedom (sexual revolution) promotes the activation of genetic predispositions that affect fertility. We show that the exclusion of censored information (i.e., on the childless) by previous studies biased their results.

Observing with Sibling and Twin Telescopes

Plank, Lucia; Lovell, Jim; McCallum, Jamie; Mayer, David

2016-12-01

With the transition to VGOS, co-located radio telescopes will be common at many sites. This can be as a sibling telescope when a VGOS antenna is built next to a legacy one, or as the concept of a twin telescope with two identical VGOS antennas. The co-location of two antennas offers new possibilities in both operation and analysis. The immediate question for observing with sibling/twin telescopes is the applied observing strategy and its realization in the scheduling software. In this contribution we report about our efforts implementing new scheduling modes for sibling and twin telescopes in the Vienna VLBI Software. For the example of the sibling telescope in Hobart, several types of sessions will be discussed: an improved tag-along mode for the 26-m antenna (Ho), a proper implementation of the twin-mode using the antenna with the shorter slewing time, and an astrometric support mode enabling the observation of weak sources with the AuScope array.

Objective Impaired response inhibition is a key executive function deficit of attention-deficit/hyperactivity disorder (ADHD). Still, behavioral response inhibition measures do not consistently differentiate individuals with ADHD from unaffected individuals. We therefore investigated the neural correlates of response inhibition as well as the familial nature of these neural correlates. Methods fMRI measurements of neural activation during the stop-signal task along with behavioral measures of response inhibition were obtained in adolescents and young adults with ADHD (N=185), their unaffected siblings (N=111), and healthy controls (N=124). Results Stop-signal reaction times were longer in participants with ADHD, but not in their unaffected siblings, while reaction time variability and error rates were higher in both groups than in controls. Neural hypoactivation was observed in frontal-striatal and frontal-parietal networks of participants with ADHD and unaffected siblings compared to controls, whereby activation in inferior frontal and temporal/parietal nodes in unaffected siblings was intermediate between that of participants with ADHD and controls. Furthermore, neural activation in inferior frontal nodes correlated with stop-signal reaction times, and activation in both inferior frontal and temporal/parietal nodes correlated with ADHD severity. Conclusions Neural activation alterations in ADHD are more robust than behavioral response inhibition deficits and explain variance in response inhibition and ADHD severity. Although only affected participants with ADHD have deficient response inhibition, hypoactivation in inferior frontal and temporal-parietal nodes in unaffected siblings support the familial nature of the underlying neural process. Hypoactivation in these nodes may be useful as endophenotypes that extend beyond the affected individuals in the family. PMID:25615565

Pretense of parentage by siblings in immigration: Polesky's paradox reconsidered.

PubMed

Wenk, Robert E; Shao, Alison

2014-02-01

Older and younger siblings occasionally attempt to impersonate parent and child to expedite immigration under US family-based visa policies. The rate with which full siblings escape detection by current relationship tests is unknown. Retrospective study of full-sibling immigrant pairs was undertaken to determine the proportion that show insufficient genetic evidence to exclude parentage. Sibship and parentage indices (SI and PI) were compared/case in unexcluded sibling cases and true parent-child cases. Alleles shared per short-tandem-repeat locus were compared in sibling and parent-child pairs. The proportion of successful parentage fraud by siblings was estimated from the parentage exclusion rate among immigrants and the proportion of sibships without genetic inconsistencies (GIs). When 11 to 25 independent loci were tested per two-sibling case to verify or refute parentage, tests failed to demonstrate any GI in 9% and PI was greater than SI in seven of 10 of these cases. Another 29% of full-sibling pairs demonstrated insufficient evidence (fewer than two GIs) to exclude parentage. Thus, 0.4% of sibling pairs could falsely claim a parent-child relationship and show no GIs. Another 1.4% could make that false claim and not present sufficient evidence to be excluded. At present, with no evidence of parentage exclusion in a full-sibling pair, the relative magnitudes of PI and SI are misleading relationship indicators because too few loci are examined and rates of sharing one and two alleles/locus vary greatly in parentage and sibling pairs. Only evidence of exclusion ascertains false parentage claims by siblings. Nevertheless, the expected rate of successful fraud is quite low. © 2013 American Association of Blood Banks.

The clinical spectrum of cystic fibrosis (CF) is influenced by the cystic fibrosis transmembrane conductance regulator (CFTR) genotype. However, variable courses of the disease were demonstrated among patients with identical genotypes. Since siblings share identical CFTR mutations and environmental factors, they can serve as a model to assess the effect of modifier genes on disease expression, and also to evaluate cross-infection. The aim of this study was to compare disease expression among siblings with CF. All sibling pairs treated at 7 CF centers in Israel were included in the study. Data were collected from patients' medical charts. Fifty families with at least 2 siblings were identified. As expected, the second-born sibling was diagnosed at an earlier age compared to the first-born. The mode of CF presentation at diagnosis showed significant familial concordance. In the families where the first sibling presented with gastrointestinal manifestations, 79% of the second siblings also presented with gastrointestinal manifestations. When gastrointestinal manifestations were absent in the first sibling, only 12% of the second siblings presented with gastrointestinal manifestations (P < 0.0001). Likewise, when the first sibling presented with respiratory symptoms, 60% of the second siblings presented with the similar symptoms. However, when the first sibling presented without respiratory symptoms, only 12% of the second siblings presented with respiratory symptoms (P < 0.001). Meconium ileus (MI) was present in 20 patients (21%). In 10 families where the first-born sibling had MI, 8 (80%) of the subsequent siblings had MI. On the other hand, in the 39 families where the first-born sibling did not have MI, only 2 (5%) subsequent siblings had MI (P < 0.001). Pancreatic insufficiency (PI) also had high familial concordance (P < 0.0001). Percentile growth for weights and heights and lung function (FVC, FEV(1), and FEF(25-75)) at ages 7 and 10 years were similar between

Sibling rivalry and the new baby: anticipatory guidance and management strategies.

PubMed

Sawicki, J A

1997-01-01

Sibling rivalry can be found in many families and frequently creates a stressful and challenging situation for parents. The arrival of a new baby often causes older siblings to feel displaced, frustrated, angry, and even unloved. Age, gender, personality and temperament, and parental behavior are factors that appear to influence the degree to which sibling rivalry occurs. Common reactions of older siblings to the birth of a new baby include aggression toward the newborn, behavioral regression, and attention seeking behavior, as well as independence and maturity. Anticipatory guidance is recommended to help parents adequately prepare their older child for the arrival of a new sibling. Strategies for managing sibling rivalry include open parent-child communication, equal treatment of siblings, non-intervention in sibling conflicts, distraction, and separation. Parents can minimize feelings of jealousy between siblings by providing a supportive, nurturing environment that allows each child to feel secure and loved.

Research and clinical practice in first-episode psychosis (FEP) has predominantly focused on parents and partners and has neglected siblings needs. This study aims to characterize the sibling relationship in FEP and to examine the illness-related variables that influence this relationship. Survey methodology explored the experience of 157 siblings during the first 18 months of their brother or sister's treatment. The Adult Sibling Relationship Questionnaire was used to measure the warmth, conflict, and rivalry within the relationship. A series of multivariate regression analyses were conducted to determine the relationship between illness characteristics and sibling relationship. When the young person experiencing FEP had a period of untreated psychosis longer than six months, required more than one hospital admission, had persisting psychotic symptoms, continued to use substances, and/or had a history of physical violence, warmth within the sibling relationship deteriorated. Regression analysis revealed that a history of violence was a significant predictor of the warmth, conflict, and rivalry within the sibling relationship. Suicide attempts were a significant predictor of conflict. This study has established associations between the sibling relationship and illness-related variables. This study promotes consideration of the importance of including siblings in early intervention. Given the powerful role this relationship can have as a protective factor, this study could inform future interventions involving siblings.

Objective The interaction of food reinforcement and the inability to delay gratification are related to adult energy intake and obesity. This study was designed to test the association of sibling pair differences in relative reinforcing efficacy of food and delay discounting on sibling pair differences in zBMI scores of same-gender zBMI-discordant siblings. Design and methods We tested main and interactive relationships between delay discounting and relative reinforcing efficacy of food on zBMI discordance in 14 zBMI-discordant biological sibling pairs (6 female pairs) using a discordant sibling study design. Results Sibling pair differences in relative reinforcing efficacy of food were associated with sibling pair differences in zBMI (p = 0.046); this effect was moderated by delay discounting (p < 0.002). Sibling pairs with greater differences in relative reinforcing efficacy and delay discounting had greater differences in zBMI. Conclusions The combination of greater sibling pair differences in delay discounting and relative reinforcing efficacy is associated with greater discordance in zBMI in adolescent sibling pairs.

Although gratitude is a key prosocial emotion reinforcing reciprocal altruism, it has been largely ignored in the empirical literature. We examined feelings of gratitude and the importance of reciprocity in same-sex peer relations. Participants were 772 individuals (189 men; mean age = 28.80) who completed an online survey using a vignette design. We investigated (i) differences in reported gratitude and the importance of reciprocity among same-sex siblings and same-sex friends, and (ii) how relationship closeness moderates these associations. Based on the theory of kin altruism, we expect that people would feel more grateful towards friends than towards their siblings, and that lack of gratitude or failure to pay back a loan would bother more with friends than with siblings, irrespective of emotional closeness. Results showed that levels of gratitude and expectations of reciprocity were higher towards friends compared to siblings. This was the case also after controlling for emotional closeness. Being close generally made participants feel more grateful and expect lower displays of gratitude in the other. Closeness was also strongly associated with emotional gratitude among siblings compared to friends. We conclude that feelings and displays of gratitude have a special role in friendships. Although a close sibling may elicit as much gratitude as a friend does, even a very close friend is not exempt from the logic of reciprocity in the same way that a sibling is.

The purpose of this research project was to understand, primarily from the sibling perspective, the effect of a child's major burn injury on his or her sibling. A mixed method qualitative dominant design was implemented using the life story method for the qualitative portion. Additionally, the Sibling Relationship Questionnaire -Revised (SRQ-R) was used as a structured interview guide and for calculating scoring data to explore sibling relationship factors of warmth/closeness, rivalry, conflict, and relative status/power. Participants from 22 family cases (one or multiple family members) and 40 individuals were interviewed. To capture impact on the family over time, interviews began a minimum of two years post-burn. The central thematic pattern for the sibling relationship in families having a child with a major burn injury was that of normalization. Two components of normalization were described: areas of normalization and the process of adjustment. Areas of normalization were found in play and other activities, in school and work, and in family relations with siblings. The process of adjustment was varied and often gradual, involved school and work re-entry, and in some instances, seemed to change life perspective. Clinical implications in providing family-centered care can focus on promoting normalization by assessing and supporting siblings who may only be occasionally seen in the hospital or clinic.

Background Given previous evidence of familial predisposition for longevity, we hypothesized that siblings and parents of supercentenarians (age ≥ 110 years) were predisposed to survival to very old age and that, relative to their birth cohorts, their relative survival probabilities (RSPs) are even higher than what has been observed for the siblings of centenarians. Methods Mean age at death conditional upon survival to ages 20 and 50 and survival probabilities from ages 20 and 50 to higher ages were determined for 50 male and 56 female siblings and 54 parents of 29 supercentenarians. These estimates were contrasted with comparable estimates based on birth cohort-specific mortality experience for the United States and Sweden. Results Conditional on survival to age 20 years, mean age at death of supercentenarians’ siblings was ~81 years for men and women. Compared with respective Swedish and U.S. birth cohorts, these estimates were 17%–20% (12–14 years) higher for the brothers and 11%–14% (8–10 years) higher for the sisters. Sisters had a 2.9 times greater probability and brothers had a 4.3 times greater probability of survival from age 20 to age 90. Mothers of supercentenarians had a 5.8 times greater probability of surviving from age 50 to age 90. Fathers also experienced an increased survival probability from age 50 to age 90 of 2.7, but it failed to attain statistical significance. Conclusions The RSPs of siblings and mothers of supercentenarians revealed a substantial survival advantage and were most pronounced at the oldest ages. The RSP to age 90 for siblings of supercentenarians was approximately the same as that reported for siblings of centenarians. It is possible that greater RSPs are observed for reaching even higher ages such as 100 years, but a larger sample of supercentenarians and their siblings and parents is needed to investigate this possibility.

Like other young people, those with autism spectrum disorder (ASD) have an impact on siblings in both positive and negative ways. Research indicates positive attributes include maturity and responsibility; positive self-concept; less quarrelling and competition; admiration for the person with ASD; and satisfactory sibling relationships. Negative attributes include fear of frightening or violent behavior, decreased sibling intimacy, and social and emotional difficulties. However, most research relies on information from parents/teachers, rather than from siblings. Therefore, this qualitative descriptive study explored experiences of 11 brothers and 11 sisters living with a young person with ASD through audiorecorded semi-structured interviews. Analysis revealed the overall theme was contradiction. Participants recognized difficulties (decreased parental attention, extra responsibility, bothersome behaviors, communication difficulties) and positive aspects (became empathetic, loved and appreciated the child, realized the experience was life-changing) of living with a young person with ASD. Younger siblings frequently reflected on childhood experiences, wished they could play together, and mentioned what the young person could do. Adolescent siblings learned life lessons from the experience, talked about life changes when ASD was diagnosed, and seemed introspective and protective toward the young person with ASD. Male siblings often wished they played more often while growing up with the young person, and frequently mentioned the child/adolescent's aggressive behaviors; female siblings focused on relationship and communication difficulties of the young person ASD. Interventions to help siblings provide positive behavioral support, engage in developmentally appropriate play, and communicate reciprocally are warranted. Nurses can help parents understand siblings' perceptions and can encourage parents to support siblings.

The purpose of this study was to empirically test if siblings of children with disability had higher levels of parent-reported behavioral and emotional functional impairment compared with a peer group of siblings residing with only typically developing children. This was a retrospective secondary analysis of data from the Medical Expenditure Panel Survey. We included only households with at least 2 children to ensure sibling relationships. Two groups of siblings were formed: 245 siblings resided in households with a child with disability and 6564 siblings resided in households with typically developing children. Parents responded to questions from the Columbia Impairment Scale to identify functional impairment in their children. On the basis of parent reports and after adjusting for sibling demographic characteristics and household background, siblings of children with disability were more likely than siblings residing with typically developing children to have problems with interpersonal relationships, psychopathological functioning, functioning at school, and use of leisure time (P < .05). The percentage of siblings of children with disability classified with significant functional impairment was 16.0% at the first measurement period and 24.2% at the second (P < .001). For siblings of typically developing children there was a smaller percentage increase from 9.5% to 10.3% (P < .001). Functional impairment is a key indicator for the need of mental health services and, as such, early assessment and interventions to limit increasing severity and short- to long-term consequences need to be addressed. Health care professionals need to consider a family-based health care approach for families raising children with disability.

2005-01-01

Sibling relationships may be relevant to the development of anorexia nervosa (AN), yet little research has focused on this aspect of the disorder. A narrative study of four women in various stages of recovery from AN is described and results relevant to sibling relationships are presented, enriched by published anecdotes and case studies. The anorexic interviewees described much antagonism and rivalry and little warmth and intimacy between themselves and their siblings. They seemed to feel they did not belong sufficiently in their families and other social settings despite a strong desire to belong. The sample is small, reports subjective and retrospective and no control group was included. It is suggested that anorexic girls often feel emotionally isolated from and misunderstood by siblings, who may have much to contribute to the process of therapy and recovery.

Sibling sexual abuse: why don't we talk about it?

Yates, Peter

2017-08-01

To explore two hypotheses for explaining why there is little written about sibling sexual abuse and to raise awareness of the subject in order better to protect children and to facilitate sensitive patient care. While there is no universal agreement over its definition, sibling sexual abuse is acknowledged internationally as a prevalent form of child sexual abuse but tends not to be recognised by health professionals. It is also under-represented within the literature in comparison with other forms of intrafamilial sexual abuse. Understanding why this is may help to illuminate the potential barriers to effective professional responses. Two explanations which emerge strongly are the existence of a sibling incest taboo and a prevailing belief that sibling sexual behaviour is largely harmless. Discursive position paper. The paper examines the two hypotheses through exploration of the extant literature on sibling incest and sibling sexual abuse. Sibling sexual abuse accounts for a significant minority of child sexual abuse and has the potential to be as harmful as sexual abuse by a parent. An abhorrence at the thought of sibling sexual activity and a prevailing view of its harmlessness may hinder nurses' detection of and appropriate responses to sibling sexual abuse, but do not provide convincing explanations for the dearth of literature. Instead, a deeply held perspective of sibling relationships as non-abusive offers a more profound explanation. A knowledge of sibling sexual abuse and its consequences are important both for the effective protection of children and the sensitive and appropriate treatment of patients who present with a variety of physical and mental health concerns. A perspective that sibling relationships are non-abusive provides a deeper level of understanding of the powerful obstacles to raising awareness of and responding appropriately to this form of abuse. © 2016 John Wiley & Sons Ltd.

Sibling aggression among maltreated children placed in foster homes is linked to other externalizing problems and placement disruption. The reduction of sibling conflict and aggression may be achieved via a multicomponent ecologically focused intervention for families in the foster care system. The focus of the study is to evaluate the feasibility and short-term effectiveness of a transtheoretical intervention model targeting sibling pairs and their foster parent that integrates family systems, social learning theory, and a conflict mediation perspective. In this pilot study, sibling pairs (N=22) and their foster parent were randomized into a three-component intervention (n=13) or a comparison (n=9) group. Promoting Sibling Bonds (PSB) is an 8-week prevention intervention targeting maltreated sibling pairs ages 5–11 years placed together in a foster home. The Siblings, Parent, and Joint components were delivered in a program package at the foster agency by a trained two-clinician team. Average attendance across program components was 73%. Outcomes in four areas were gathered at pre-and post-intervention: observed sibling interaction quality (positive and negative) including conflict during play, and foster parent reports of mediation strategies and sibling aggression in the foster home. At post-intervention, adjusting for baseline scores and child age, intervention pairs showed higher positive (p<.001) and negative (p<.05) interaction quality, and lower sibling conflict during play (p <.01) than comparison pairs. Foster parents in the intervention group reported a higher number of conflict mediation strategies than those in the comparison group (p <.001). Foster parents in the intervention group reported lower sibling physical aggression from the older toward the younger child than those in the comparison group (p <.05). Data suggest that the PSB intervention is a promising approach to reduce conflict and promote parental mediation which together may reduce

To better understand the nature of sibling relationships among children in foster or adoptive placement and the challenges and processes involved in maintaining these relationships, we conducted an exploratory analysis of data collected from semi-structured interviews with caregivers of 14 foster and adopted children in San Diego County. We identified three patterns of placement histories and living situations which appeared to impact the degree of contact maintained with siblings: (1) children who had never lived together and were not currently placed together; (2) children who at some point lived with or were placed together with their siblings, but were now separated from them; and (3) children who had lived with their siblings all their life and were placed together with at least some of their siblings at the time of the interview. Children's current living situations and placement histories, caregivers' experiences and perceptions of feasibility and desirability of sibling contact, and the sibling relationship itself are primary determinants in the development and maintenance of contact between siblings. Implications for child welfare policy and practice are discussed.

Early-life exposure to older siblings is associated with a lower risk of asthma. To date, no study has addressed the impact of having siblings on both the airway and fecal microbiota during infancy. The aim of this study was therefore to profile the nasal airway and fecal microbiota in infants, and to examine the association between having siblings and microbiota profile. We conducted a cross-sectional study of 105 healthy infants (aged <1 year). Using 16S rRNA gene sequencing and an unbiased clustering approach to the nasal airway and fecal samples, we identified microbiota profiles and then determined the association between having siblings and microbiome profile. Overall, the median age was 3.4 months (IQR, 2.0-4.7 months); 43% had siblings in the household. Unbiased clustering of nasal airway microbiota identified three profiles: Moraxella dominant (43%), Corynebacterium/Dolosigranulum dominant (36%), and mixed (21%). Infants with siblings were more likely to have a Moraxella-dominant profile than Corynebacterium/Dolosigranulum-dominant profile (76% vs 18%), while those without siblings had the opposite pattern (18% vs 50%; P < 0.001, multivariable-adjusted). Fecal microbiota consisted of three profiles: Bifidobacterium dominant (39%), Escherichia dominant (31%), and Enterobacter dominant (30%). Infants with siblings were more likely to have a Bifidobacterium-dominant profile than Escherichia-dominant profile (49% vs 24%) while those without siblings had the opposite pattern (32% vs 37%; P = 0.04, multivariable-adjusted). In this cross-sectional study, infants with siblings were more likely to have a Moraxella-dominant nasal microbiota profile and Bifidobacterium-dominant fecal microbiota profile. These findings should facilitate further investigation of the interplay between early-life environmental exposure, the microbiome, and childhood asthma. © 2016 Japan Pediatric Society.

Background Few studies have examined changes in siblings after the death of a brother or sister, particularly from mother, father, and sibling perspectives within the first year post-death. Objective This descriptive study identified and assessed the frequency of changes in siblings after a child's death from cancer. Methods Participants were recruited from cancer registries at three hospitals in the U.S. and Canada 3–12 months after the child's death. Thirty-six mothers, 24 fathers, and 39 siblings from 40 families were included. Semi-structured interviews using open-ended questions were conducted with each parent and sibling separately in the home. Content analysis identified emerging themes, and McNemar tests compared frequencies between each paired set of reports (sibling vs. mother, sibling vs. father, mother vs. father). Results Sixty-nine percent of participants reported personal changes in siblings (e.g., changes in personality, school work, goals/life perspective, activities/interests). Forty-seven percent noted changes in siblings' relationships with family members and peers. Only 21% of participants reported no changes attributed to the death. Comparisons of frequencies across informants were not significant. Conclusions Most siblings experienced changes in multiple areas of their lives after the death of a brother or sister to cancer. Some changes reflected siblings that were positively adapting to the death, while other changes reflected difficulties. Implications for practice Our findings offer guidance to improve aftercare for bereaved siblings and their families. Additional research is needed to further delineate the needs of bereaved siblings and to develop strategies to promote adaptation to loss. PMID:22067687

Existing research on aggression tends to narrowly focus on peers; less is known about sibling aggression, most likely due to its historical acceptance. Aggression is characterized by its forms (i.e., physical vs. social or relational aggression) and its functions (i.e., the motivations behind the aggressive act and categorized as proactive vs. reactive aggression). We use data from a two-wave study of middle (n = 197; M age = 12.63 years at Wave 1) and older (n = 159; M age = 16.50 years at Wave 1) adolescents to assess the extent to which proactive and reactive functions of sibling aggression make unique or conditional contributions to adolescent adjustment (i.e., depression, delinquency, and substance use). We find that proactive sibling aggression increases risk for problem substance use and delinquent behavior, reactive sibling aggression increases risk for depressed mood and delinquent behavior, and such results are observed even with statistical adjustments for sociodemographic and family variables, stressful life events, and prior adjustment. Few conditional effects of proactive or reactive sibling aggression by sex or grade are observed; yet, for all three outcomes, the harmful effects of reactive sibling aggression are strongest among adolescents who report low levels of proactive sibling aggression. The results speak to the importance of understanding the proactive and reactive functions of sibling aggressive behaviors for adolescent adjustment. © The Author(s) 2014.

Double impact: what sibling data can tell us about the long-term negative effects of parental divorce.

PubMed

Wolfinger, Nicholas H; Kowaleski-Jones, Lori; Smith, Ken R

2003-01-01

Most prior research on the adverse consequences of parental divorce has analyzed only one child per family. As a result, it is not known whether the same divorce affects siblings differently. We address this issue by analyzing paired sibling data from the 1994 General Social Survey (GSS) and 1994 Survey of American Families (SAF). Both seemingly unrelated regressions and random effects models are used to study the effect of family background on offspring's educational attainment and marital stability. Parental divorce adversely affects the educational attainment and the probability of divorce of both children within a sibship; in other words, siblings tend to experience the same divorce the same way. However, family structure of origin only accounts for a trivial portion of the shared variance in offspring's educational attainment and marital stability, so parental divorce is only one of many factors determining how offspring fare. These findings were unchanged when controlling for a number of differences both between and within sibships. Also, the negative effects of parental divorce largely do not vary according to respondent characteristics.

Siblings play a key, supportive role in the lives of many lesbian and gay adults. Yet siblings are rarely considered in the literature regarding the coming-out process (D'Augelli et al., 1998; Hilton & Szymanski, 2011; LaSala, 2010; Savin-Williams & Dubé, 1998). To fill this gap in the research literature, we carried out a comparative case study in the country of Belgium between two sets of siblings-three Romani brothers with one sibling identifying as a gay male and three White sisters with one sibling identifying as a lesbian. These two cases were pulled from a larger qualitative study (Haxhe & D'Amore, 2014) of 102 native French-speaking Belgian participants. Findings of the present study revealed that siblings offered critical socio-emotional support in the coming out of their lesbian and gay sibling, particularly with disclosing to parents and with fostering self-acceptance.

Transfusion-dependent thalassemia (TDT) and its treatment affect the physical, emotional, and social functioning, impairing the quality of life (QoL). There are few studies on QoL of adolescent with TDT. Its effect on their siblings' QoL has not been studied so far. In this cross-sectional study, 40 adolescents with TDT, 28 siblings, and 40 controls were studied to assess the QoL of adolescents thalassemics, and their siblings using the shorter version of World Health Organization Quality of Life instrument, the WHOQOL-BREF. Thalassemics had poor perception of their general health and scored significantly lower in all the subscales compared with the controls. Lowest mean subscale scores were for physical (57.7 vs. 72.4, P<0.001), and psychological domains (56.7 vs. 72.3, P<0.001). Their siblings also scored significantly less in environment domain. Prevalence of school dropout, short stature, and delayed puberty were significantly higher in thalassemics. Pretransfusion hemoglobin, age at onset of anemia, and chronological age were found to be significant predictors of total summary scores. This study showed that the concept of QoL is a cumulative reflection of individual and disease variables and highlights the negative impact of thalassemia on the patients' QoL and some aspects of their siblings' lives also.

The current study investigated how having at least one child sibling influenced children's dishonest behaviors. Furthermore, for those children with a sibling, we examined whether having a younger or older sibling and the age difference between siblings influenced deceptive acts. Children between 3 and 8 years of age (N = 130) completed the temptation resistance paradigm, where they played a guessing game and were asked not to peek at a toy in the experimenter's absence. Children's peeking behavior was used as a measure of cheating, and children's responses when asked whether they had peeked were used as measures of lie-telling. Results demonstrate that siblings do indeed influence children's deceptive behaviors. First, children with a sibling were significantly more likely to cheat compared with children without any siblings. Next, for those with a sibling, children with a larger age difference with their younger sibling(s) were significantly more likely to lie compared with children closer in age, and children with a younger sibling were significantly more likely to maintain their lie during follow-up questioning compared with children with an older sibling.

Children with siblings coping with chronic illness experience stresses and disruptions in daily life as families work together to care for the affected child. Research suggests that children and adolescents with sickle cell disease (SCD) may be at risk for adjustment problems, impaired psychosocial functioning, and reduced quality of life. These potential stressors affect the child with SCD as well as their caregivers and other family members. This study examined the role of family functioning on the psychosocial functioning of healthy siblings of children with SCD. Participants were 65 healthy African-American siblings of children with SCD with a mean age of 11.19 years (range: 7-16) and their primary caregiver. Caregivers completed questionnaires assessing family functioning and child adjustment including demographic surveys, the Family Relations Scale (FRS), and the Child Behavior Checklist (CBCL). Increased number of emergency room visits (β = -0.28, P < 0.05) predicted poor psychosocial adjustment in siblings. Family functioning mediated this effect (β = 0.27; P < 0.05). High levels of family expressiveness (total score, r = -0.34; P < 0.01), support (total score, r = -0.54; P = 0.001), and low levels of family conflict (total score, r = 0.41; P < 0.001) were associated with improved adjustment among healthy siblings of children with SCD. Awareness of the possible negative psychosocial outcomes of living with a sister or a brother with SCD is important for clinicians. In particular, interventions that focus on family expressiveness, support, and conflict are indicated for this population. Copyright © 2011 Wiley-Liss, Inc.

There is a need for research to identify factors influencing intentions to undergo colorectal cancer (CRC) screening among family members at risk for CRC. This study tested a mediational model primarily guided by Ronis' elaboration of the Health Belief Model in predicting intention to have colorectal cancer screening among siblings of individuals diagnosed with colorectal cancer prior to age 56 years. Data were collected from 534 siblings of individuals diagnosed with CRC. A baseline survey was administered by telephone. Measures included perceived susceptibility, CRC severity, physician and family support for CRC screening, cancer-specific distress, the closeness of the relationship with the affected sibling, and future intention to have a colonoscopy. Participant age, gender, and number of prior colonoscopies, as well as the stage of the affected patient's cancer and time from the patient's diagnosis to the interview, were controlled for in the analyses. The proposed model was not a good fit to the data. A respecified model was fit to the data. In this model, physician support, family support, and sibling closeness were significantly associated with both perceived benefits and barriers. Perceived severity was associated with barriers. Benefits and barriers, as well as cancer-specific distress, were directly associated with colonoscopy intentions. Results were consistent with a mediational role for benefits and barriers in the associations of sibling closeness and with a mediational role for barriers in the association between perceived severity and colonoscopy intentions. Family and physician support impacted intentions both directly and indirectly through effects on benefits and barriers. Perceived risk was not associated with benefits, barriers, or colonoscopy intentions. Intervention efforts to increase colonoscopy intentions may benefit from targeting family influences, particularly the affected proband in the family, as well as physician influence, cancer

Maternal regulation of sibling interactions in the preschool years: observational study in Japanese families.

Kojima, Y

2000-01-01

Characteristics of three maternal regulating behaviors--(1) reference to one sibling's actions or emotional states toward the other sibling, (2) encouragement of sibling interactions, (3) distraction of one sibling's attention away from the other sibling-and their associations with children's positive and negative behaviors toward their siblings were investigated through semistructured home observations for 40 sibling pairs (1-4 years, 2-8 years) and their mothers in Japanese families. Maternal regulating behaviors were observed more frequently when the younger sibling was still in an early developmental stage in the preschool years, although the findings were modest. The older sibling's negative behaviors toward the younger sibling positively correlated with maternal distraction toward the younger; alternatively, the younger sibling's negative behaviors do not correlate with maternal distraction but do correlate with maternal encouragement directed toward the older sibling. Reliable associations were found between maternal regulating behaviors and prosocial exchanges between siblings; maternal reference to the younger sibling's actions or emotional states directed toward the older sibling was associated with the older sibling's positive behavior toward the younger sibling. Maternal regulating behaviors during mother-sibling triadic interactions were associated with the quality of sibling relationships.

Well sibling psychological adjustment to chronic physical disorder in a sibling: how important is maternal awareness of their illness attitudes and perceptions?

PubMed

Taylor; Fuggle, P; Charman, T

2001-10-01

The psychological adjustment of healthy siblings was investigated in relation to their attitudes and perceptions about their brother's or sister's chronic physical disorder, to their mothers' awareness of these attitudes and perceptions, and to three other maternal factors (maternal distress, maternal social support, and amount of care demanded by the physical disorder). Sixty-two well siblings and mothers of children with a range of chronic physical disorders completed standardised questionnaires. The majority of siblings did not appear to have adjustment problems, although the sample had slightly increased rates of emotional symptoms compared to the general population. Mothers rated well siblings as having more negative attitudes and perceptions about the physical disorder than reported by siblings themselves. A multiple regression analysis indicated that better sibling adjustment was associated with higher maternal awareness of their attitudes and perceptions. These findings support Varni and Wallander's (1998) model that emphasises the role of relationship and attitude variables in child adjustment to chronic physical disorder. The implications of these findings for clinical practice are discussed.

Siblings have been shown to reduce the risk of childhood asthma and allergy, but the mechanism driving this association is unknown. The objective was to study whether siblings affect the airway immune response in healthy neonates, which could represent an underlying immune modulatory pathway. We measured 20 immune mediators related to the Type 1, Type 2, Type 17, or regulatory immune pathways in the airway mucosa of 571 one-month-old asymptomatic neonates from the Copenhagen Prospective Studies on Asthma in Childhood2010 birth cohort (COPSAC2010 ). The association between airway mediator levels and presence of siblings was investigated using conventional statistics and principle component analysis (PCA). Neonates with siblings had an upregulated level of airway immune mediators, with predominance of Type 1- and Type 17-related mediators. This was supported by the PCA showing a highly significant difference between children with vs without siblings: P < 10(-10) , which persisted after adjustment for potential confounders including pathogenic airway bacteria and viruses: P < 0.0001. The immune priming effect was inversely associated with time since last childbirth: P = 0.0015. Siblings mediate a Type 1/Type 17-related immune-stimulatory effect in the airways of asymptomatic neonates, also after adjustment for pathogenic bacteria and viruses, indicating that siblings exert a transferable early immune modulatory effect. These findings may represent an in utero immune priming effect of the fetal immune system caused by previous pregnancies as the effect was attenuated with time since last childbirth, or it could relate to the presence of unidentified microbes, but further studies are needed to confirm our findings. © 2016 John Wiley & Sons A/S.

What are infant siblings teaching us about autism in infancy?

International research to understand infant patterns of development in autism spectrum disorders has recently focused on a research paradigm involving prospective longitudinal studies of infant siblings of children with autism. Such designs use a comparison group of infant siblings without any familial risks (the low- risk group) to gather longitudinal information about developmental skills across the first three years of life, followed by clinical diagnosis of ASD at 36 months. This review focuses on five topics: presence of ASD in the infant sibling groups, patterns and characteristics of motor development, patterns and characteristics of social and emotional development, patterns and characteristics of intentional communication, both verbal and nonverbal, and patterns that mark the onset of behaviors pathognomonic for ASD. Symptoms in all these areas typically begin to be detected during the age period of 12 –24 months in infants who will develop autism. Onset of the symptoms occurs at varying ages and in varying patterns, but the pattern of frank loss of skills and marked regression reported from previous retrospective studies in 20–30% of children is seldom reported in these infant sibling prospective studies. Two surprises involve the very early onset of repetitive and unusual sensory behaviors, and the lack of predictive symptoms at age 6 months. Contrary to current views that autism is a disorder that profoundly affects social development from the earliest months of life, the data from these studies presents a picture of autism as a disorder involving symptoms across multiple domains with a gradual onset that changes both ongoing developmental rate and established behavioral patterns across the first two to three years of life.

2016-02-01

Research indicates that older siblings uniquely influence their younger brothers' and sisters' substance use behaviors during adolescence; however, the underlying mechanisms of socialization are rarely examined. The present study investigated whether social and/or cognitive pathways mediated the association between adolescent siblings' alcohol use and whether these pathways were moderated by the gender composition of the sibling dyad. Participants included one parent and two adolescent siblings (M age=14.52 and 17.17years) from 326 families. Data were collected via telephone interviews. Path analysis demonstrated that the association between older and younger siblings' alcohol use was mediated via social and cognitive pathways. Specifically, older siblings' drinking was positively related to the frequency of siblings' co-use as well as more positive expectations about alcohol, which in turn were positively associated with younger siblings' alcohol use. Identifying the ways in which siblings influence each other's substance use and health is critical because they are emerging and effective targets of intervention and prevention. Copyright © 2015.

[Early sibling aggression in mammals and its hormonal correlates].

PubMed

Antonevich, A L; Naĭdenko, S V

2007-01-01

Early sibling aggression is a widespread phenomenon in birds. Ornithologists distinguish species with "obligate" and "facultative" siblicide. Sibling aggression was described in some mammal species: the domestic pig (Sus scrofa), the spotted hyena (Crocuta crocuta), the Eurasian lynx (Lynx lynx), and the Iberian lynx (L. par-dinus). In all of them, sibling aggression corresponds well with the "facultative" siblicide model in birds. Sibling aggression was observed at the age of 36-64 days in both lynx species. It is usually restricted to a single fight and can change the hierarchical structure and growth rate of the kittens. In the spotted hyena and the domestic pig, the frequency and intensity of aggressive interactions between siblings are strongest during the first days of postnatal ontogeny and then decrease gradually. The newborns of these species are much developed than newborn lynx kittens. Usually adult lynx females, in contrast to hyenas and pigs, try to stop sibling fights. This is probably related to the larger parental investment at the time of the fight in lynxes (a kitten's body weight is about 10% of the mother's) than in pigs (0.5%) and hyenas (1.9%). Sibling aggression in spotted hyenas could be related to the high level of androstenedione and is not related to testosterone concentration. In the Eurasian lynx, female sibs attack their littermates slightly more often than male sibs do, and sibling aggression is not testosterone-dependent. Hormones secreted by the adrenal glands may play an important role in this phenomenon. The data available so far, however, do not positively confirm the presence of hormonal trigger effects in mammal sibling aggression.

This study investigated school functioning among unaffected siblings of youths with autistic spectrum disorder (ASD) and identified the correlates for school maladjustment. We recruited 66 youths with a clinical diagnosis of ASD, aged 8-19, their unaffected siblings and 132 typically developing controls (TD). We found that ASD youths had poorer school functions than unaffected siblings and TD. Unaffected siblings had poorer attitude toward schoolwork and more severe behavioral problems at school than TD. Several associated factors for different scholastic functional domains (i.e., academic performance, attitude toward school work, social interactions, behavioral problems) in the siblings included IQ, autistic traits, inattention/oppositional symptoms, sibling relationships, etc. Our findings suggest the need of assessing school functions in unaffected siblings of ASD.

Autonomy-supportive parenting yields manifold benefits. To gain more insight into the family-level dynamics involved in autonomy-supportive parenting, the present study addressed three issues. First, on the basis of self-determination theory, we examined whether mothers' satisfaction of the psychological needs for autonomy, competence, and relatedness related to autonomy-supportive parenting. Second, we investigated maternal autonomy support as an intervening variable in the mother-child similarity in psychological need satisfaction. Third, we examined associations between autonomy-supportive parenting and autonomy-supportive sibling interactions. Participants were 154 mothers (M age = 39.45, SD = 3.96) and their two elementary school-age children (M age = 8.54, SD = 0.89 and M age = 10.38, SD = 0.87). Although mothers' psychological need satisfaction related only to maternal autonomy support in the younger siblings, autonomy-supportive parenting related to psychological need satisfaction in both siblings and to an autonomy-supportive interaction style between siblings. We discuss the importance of maternal autonomy support for family-level dynamics. © 2015 by the Society for Personality and Social Psychology, Inc.

Most American youth have siblings. This study examined the influence of early adolescents' perceptions of their older sibling's sexual activity on their own sexual attitudes and behaviors. Early adolescents (ages 12-14) at risk for emotional/behavioral problems reported on attitudes towards sex, sexual behaviors, and perception of older siblings' and peers' sexual activity and perceived parental approval toward sex. The sample was divided into 3 groups: teens who thought their older sibling was not having sex (N = 119), teens who believed their sibling was sexually active (N = 55), and teens without an older sibling (N = 170). Teens who thought their older sibling was not having sex scored higher in valuing abstinence and lower on perceptions of peer sex and maternal approval toward sex than teens who perceived their sibling to be having sex and teens without an older sibling. Regarding behaviors, teens who thought their older sibling was not having sex were less likely to endorse making out, touching genitals, oral sex, and vaginal sex compared with teens who thought their older sibling was having sex. Perceptions that older siblings abstain from sexual activity may be a protective factor for more conservative attitudes towards sex and decreased sexual activity among young at-risk teens. A single question about perceptions of siblings' sexual behaviors can be integrated into health care visits to introduce conversations about age-appropriate sexual decision-making.

Background Siblings of children with vesicoureteral reflux (VUR) are at elevated risk of VUR. Screening siblings may identify VUR prior to a clinical illness such as a urinary tract infection (UTI), but the benefit of screening has not been demonstrated. We sought to determine the incidence of UTI among siblings, and hypothesized that the sibling UTI rate is similar between screened and unscreened siblings. Methods We performed a retrospective cohort analysis using insurance claims data (1/1/00-12/31/09). Within each family, we identified the index VUR patient and siblings, and included siblings who were enrolled in the insurance plan from birth for at least 1 year. We identified siblings who were screened for VUR and/or had UTI. We investigated the association of screening and UTI, controlling for patient characteristics and clustering within families. Results Among 617 siblings (associated with 497 index patients), 317 (51%) were female. Median insurance enrollment time was 53.0 months, with 424 enrolled ≥3 years. Among those with 1 or 3 years of enrollment, proportion of siblings who experienced UTI was 8.4% (52/617) and 10.4% (44/424), respectively. Median age at initial UTI was 32.7 months. 223 siblings (36.0%) underwent sibling screening. There was no significant difference in UTI between screened and unscreened siblings (OR [95%CI]: 1.57 [0.87-2.85]; p=0.14). In multivariate analysis, screening was not associated with sibling UTI incidence (OR [95%CI]:1.33 [0.68-2.60]; p=0.40). Conclusions Although UTI is relatively common among siblings of VUR patients, there was no statistically significant difference in UTI incidence between screened and unscreened siblings.

Sibling aggression among maltreated children placed in foster homes is linked to other externalizing problems and placement disruption. The reduction of sibling conflict and aggression may be achieved via a multicomponent ecologically focused intervention for families in the foster care system. The focus of the study is to evaluate the feasibility and short-term effectiveness of a transtheoretical intervention model targeting sibling pairs and their foster parent that integrates family systems, social learning theory, and a conflict mediation perspective. In this pilot study, sibling pairs (N = 22) and their foster parent were randomized into a three-component intervention (n = 13) or a comparison (n = 9) group. Promoting Sibling Bonds (PSB) is an 8-week prevention intervention targeting maltreated sibling pairs ages 5-11 years placed together in a foster home. The siblings, parent, and joint components were delivered in a program package at the foster agency by a trained two-clinician team. Average attendance across program components was 73 %. Outcomes in four areas were gathered at pre- and postintervention: observed sibling interaction quality (positive and negative) including conflict during play, and foster parent reports of mediation strategies and sibling aggression in the foster home. At postintervention, adjusting for baseline scores and child age, intervention pairs showed higher positive (p < 0.001) and negative (p < 0.05) interaction quality and lower sibling conflict during play (p < 0.01) than comparison pairs. Foster parents in the intervention group reported a higher number of conflict mediation strategies than those in the comparison group (p < 0.001). Foster parents in the intervention group reported lower sibling physical aggression from the older toward the younger child than those in the comparison group (p < 0.05). Data suggest that the PSB intervention is a promising approach to reduce conflict and promote

Neuroimaging studies have identified alterations in frontostriatal circuitry in OCD. Voxel-based morphometry (VBM) allows for the assessment of differences in gray matter density across the whole brain. VBM has not previously been used to examine regional gray matter density in pediatric OCD patients and the siblings of pediatric OCD patients. Volumetric magnetic resonance imaging (MRI) studies were conducted in 10 psychotropic-naïve pediatric patients with OCD, 10 unaffected siblings of pediatric patients with OCD, and 10 healthy controls. VBM analysis was conducted using SPM2. Statistical comparisons were performed with the general linear model, implementing small volume random field corrections for a priori regions of interest (anterior cingulate cortex or ACC, striatum and thalamus). VBM analysis revealed significantly lower gray matter density in OCD patients compared to healthy in the left ACC and bilateral medial superior frontal gyrus (SFG). Furthermore, a small volume correction was used to identify a significantly greater gray matter density in the right putamen in OCD patients as compared to unaffected siblings of OCD patients. These findings in patients, siblings, and healthy controls, although preliminary, suggest the presence of gray matter structural differences between affected subjects and healthy controls as well as between affected subjects and individuals at risk for OCD.

This study assessed the effects of a group intervention-Siblings Coping Together (SibCT)-on siblings' and caregivers' anxiety symptoms compared to controls, and potential moderators. Seventy healthy siblings of children on or off treatment (7-16 y old, 41 males) participated in a randomized controlled trial (RCT) with 2 arms/groups: SibCT (n = 41) and an attention control (CG) (n = 34). Both groups had eight 2-hour weekly sessions. EG followed SibCT's educational, social, and problem-solving activities. CG had planned games and crafts. Siblings and caregivers self-reported on anxiety symptoms at baseline, intervention end, and 3 months later. Multivariable mixed model analyses examined the intervention effect over time, and potential moderators (gender, on/off ill child's treatment). No main effects of group or time were found in sibling scores. A group × gender interaction (P < .05) indicated that in the intervention group female siblings reported less total anxiety symptoms than male siblings, with no significant gender differences in the control group. Caregivers' total anxiety symptoms declined over time (P < .02). A group × on/off treatment interaction in physiological/panic subscale (P < .03) indicated that when ill child was on treatment, caregivers of siblings in SibCT reported less anxiety compared with caregivers of CG. There was no clear SibCT intervention effect. SibCT may benefit female siblings, and caregivers whose ill child is on active treatment. Contextual factors (gender) seem to influence psychosocial intervention in this population. Copyright © 2018 John Wiley & Sons, Ltd.

Previous research has demonstrated the protective effect of family and sibling closeness on child adjustment, but fewer studies have investigated how closeness is promoted within families. Guided by Family Communication Patterns Theory, we tested the association between family communication and sibling emotional and behavioral closeness, and whether adoptive status moderated this relationship. Participating families included 616 adoptive and non-adoptive families with two adolescent children. Hypotheses were tested using structural equation modeling. Sibling closeness was highest in families that emphasized both conversation and conformity and lowest in families that emphasized only conversation or neither conversation nor conformity. Emotional and behavioral closeness were differentially associated with adoption status, sibling age, and sibling gender. Few moderating effects of adoption status were found. Post hoc analyses showed moderating effects of sibling gender composition. PMID:21984844

The longitudinal associations of older sibling substance use as well as dyadic sibling conflict and collusion to younger sibling substance use were examined in a community-based sample of 244 same-sex sibling pairs. Indirect effects of older siblings on younger sibling substance use were hypothesized via younger sibling deviant peer affiliation and conflict with friends. Adolescents, parents, friends, and teachers completed measures of substance use, conflict, and deviant peer involvement. Observational data were used for both measures of collusion and conflict. Findings suggest that older sibling substance use has a direct effect on younger sibling use, but relationship dynamics and reinforcement played a significant role as well. Specifically, collusion and conflict in the sibling relationship both had indirect effects through younger siblings' deviant peer affiliation. Findings validate the powerful socializing role of both siblings and peers, and elucidate the complex mechanisms through which socialization occurs. Furthermore, data underscore the importance of considering how multiple dimensions of socialization operate in the elaboration of antisocial behavior.
