Religiousness is important to adolescents in the U.S., and the significant link between high religiousness and low substance use is well known. There is a debate between multidimensional and unidimensional perspectives of religiousness (Gorsuch, 1984); yet, no empirical study has tested this hierarchical model of religiousness related to adolescent health outcomes. The current study presents the first attempt to test a bifactor model of religiousness related to substance use among adolescents (N = 220, 45% female). Our bifactor model using structural equation modeling suggested the multidimensional nature of religiousness as well as the presence of a superordinate general religiousness factor directly explaining the covariation among the specific factors including organizational and personal religiousness and religious social support. The general religiousness factor was inversely related to substance use. After accounting for the contribution of the general religiousness factor, high organizational religiousness related to low substance use, whereas personal religiousness and religious support were positively related to substance use. The findings present the first evidence that supports hierarchical structures of adolescent religiousness that contribute differentially to adolescent substance use. PMID:26043168

The mu1 opioid receptor gene, OPRM1, has long been a high-priority candidate for human genetic studies of addiction. Because of its potential functional significance, the non-synonymous variant rs1799971 (A118G, Asn40Asp) in OPRM1 has been extensively studied, yet its role in addiction has remained unclear, with conflicting association findings. To resolve the question of what effect, if any, rs1799971 has on substance dependence risk, we conducted collaborative meta-analyses of 25 datasets with over 28,000 European-ancestry subjects. We investigated non-specific risk for "general" substance dependence, comparing cases dependent on any substance to controls who were non-dependent on all assessed substances. We also examined five specific substance dependence diagnoses: DSM-IV alcohol, opioid, cannabis, and cocaine dependence, and nicotine dependence defined by the proxy of heavy/light smoking (cigarettes-per-day >20 vs. ≤ 10). The G allele showed a modest protective effect on general substance dependence (OR = 0.90, 95% C.I. [0.83-0.97], p value = 0.0095, N = 16,908). We observed similar effects for each individual substance, although these were not statistically significant, likely because of reduced sample sizes. We conclude that rs1799971 contributes to mechanisms of addiction liability that are shared across different addictive substances. This project highlights the benefits of examining addictive behaviors collectively and the power of collaborative data sharing and meta-analyses.

Background Progress in substance abuse prevention science could be accelerated by more closely aligning studies, methodologies, and intervention program testing with the ontogenetic orientations of its underlying theories and etiology research. This article introduces the Ontogenetic Prevention approach, describes some aspects of what this orientation offers for substance abuse prevention, and provides an overview of this full special issue. Methods Review of the substance abuse prevention literature illustrates specific aspects of Ontogenetic Prevention. Conclusions The Ontogenetic Prevention perspective and each of the manuscripts in this special issue provide channels whereby substance abuse prevention can evolve from a science that relies largely on universal intervention to diversification for meeting the needs of individuals under specific developmental circumstances.

Velasco, S.; Fernández-Pineda, C.

2007-12-01

A thermodynamic study of a pure substance at the triple point is presented. In particular, we show that the mass fractions of the phases coexisting at the triple point obey lever rules in the specific entropy-specific volume diagram, and the relative changes in the mass fractions present in each phase along reversible isochoric and adiabatic processes of a pure substance at the triple point are governed by the relative sizes of the segments of the triple-point line in the pressure-specific volume diagram and in the temperature-specific entropy diagram. Applications to the ordinary triple point of water and to the triple point of Al2SiO5 polymorphs are presented.

This study assessed the validity, sensitivity, and specificity of the Substance Use Risk Profile Scale (SURPS), a measure of personality risk factors for substance use and other behavioral problems in adolescence. The concurrent and predictive validity of the SURPS was tested in a sample of 1,162 adolescents (mean age: 13.7 years) using linear and logistic regressions, while its sensitivity and specificity were examined using the receiver operating characteristics curve analyses. Concurrent and predictive validity tests showed that all 4 brief scales-hopelessness (H), anxiety sensitivity (AS), impulsivity (IMP), and sensation seeking (SS)-were related, in theoretically expected ways, to measures of substance use and other behavioral and emotional problems. Results also showed that when using the 4 SURPS subscales to identify adolescents "at risk," one can identify a high number of those who developed problems (high sensitivity scores ranging from 72 to 91%). And, as predicted, because each scale is related to specific substance and mental health problems, good specificity was obtained when using the individual personality subscales (e.g., most adolescents identified at high risk by the IMP scale developed conduct or drug use problems within the next 18 months [a high specificity score of 70 to 80%]). The SURPS is a valuable tool for identifying adolescents at high risk for substance misuse and other emotional and behavioral problems. Implications of findings for the use of this measure in future research and prevention interventions are discussed. Copyright © 2012 by the Research Society on Alcoholism.

Substance Abuse Treatment Entry, Retention, and Outcome in Women: A Review of the Literature1

This paper reviews the literature examining characteristics associated with treatment outcome in women with substance use disorders. A search of the English language literature from 1975 to 2005 using Medline and PsycInfo databases found 280 relevant articles. Ninety percent of the studies investigating gender differences in substance abuse treatment outcomes were published since 1990, and of those, over 40% were published since the year 2000. Only 11.8% of these studies were randomized clinical trials. A convergence of evidence suggests that women with substance use disorders are less likely, over the lifetime, to enter treatment compared to their male counterparts. Once in treatment, however, gender is not a significant predictor of treatment retention, completion, or outcome. Gender-specific predictors of outcome do exist, however, and individual characteristics and treatment approaches can differentially affect outcomes by gender. While women-only treatment is not necessarily more effective than mixed-gender treatment, some greater effectiveness has been demonstrated by treatments that address problems more common to substance-abusing women or that are designed for specific subgroups of this population. There is a need to develop and test effective treatments for specific subgroups such as older women with substance use disorders, as well as those with co-occurring substance use and psychiatric disorders such as eating disorders. Future research on effectiveness and cost-effectiveness of gender-specific versus standard treatments, as well as identification of the characteristics of women and men who can benefit from mixed-gender versus single-gender treatments, would advance the field.

Release of neuropeptide FF (FLFQPQRF-NH2) from rat spinal cord.

PubMed

Zhu, J; Jhamandas, K; Yang, H Y

1992-10-02

Neuropeptide FF (FLFQPQRF-NH2), originally isolated from bovine brain, is an FMRF-NH2-like peptide with morphine-modulating activity. Neuropeptide FF (NPFF) is highly localized in the dorsal spinal cords where there are also specific NPFF binding sites. Furthermore, there have been studies indicating that NPFF may participate in the regulation of pain threshold in the spinal cord. However, whether NPFF can be released from the spinal cord is not known. The present experiments, using an in vitro superfusion of an isolated whole rat spinal cord, demonstrated that high concentrations of KCl or substance P caused a release of NPFF immunoreactive material (IR) from the spinal cord into the perfusion medium in a calcium-dependent manner. Substance P (1-11) also produced a detectable release of NPFF-IR in vivo although the response was quite variable. The released NPFF-IR was analyzed by an HPLC study and found to consist of NPFF and other minor immunoreactive peptides. Further studies with substance P-related peptides showed that the in vitro release of NPFF-IR could also be induced by substance P (1-7) but not by [pGlu5,Me-Phe8,Sar9]-substance P (5-11) or substance K. These results suggest that the specific substance P receptor (SP-N), which is recognized by both substance P (1-11) and substance P (1-7) rather than the tachykinin receptor, is involved in NPFF secretion from the spinal cord. In view of the role of substance P (1-11) and substance P (1-7) in sensory transmission, the results of this study further support the role of NPFF in the modulation of antinociception in the spinal cord.

Treating patients with bipolar disorder and substance dependence: lessons learned.

Weiss, Roger D

2004-12-01

Although bipolar disorder is the Axis I psychiatric disorder associated with the highest rate of co-occurring substance use disorders, little research has focused on treatments specifically designed for these patients. The author and his colleagues have developed and studied Integrated Group Therapy (IGT) for this population. This paper describes common themes that have emerged in carrying out IGT for patients with bipolar disorder and substance dependence. These include the strong emphasis on depression, as opposed to mania; the predominance of hopelessness; specific patterns of medication noncompliance; and the implications of patients' labeling their substance use as self-medication. Therapeutic aspects involved in addressing these themes are discussed.

Former substance users working as counselors. A dual relationship.

All helping professionals risk participation in "dual relationships." But in the case of former substance users working as counselors, specific dilemmas and problems are accentuated. A qualitative analysis highlights some of the ethical and personal dilemmas faced by these counselors. The data are derived from an interview study initiated in 2000 in Denmark on former substance users with 4-8 years of abstinence. Through an analysis of interview data from a larger group of former substance users, it became evident that those working as counselors experienced specific dilemmas and problems. The current article is based on individual reports of five counselors with recovery status.

Young adults with early phase schizophrenia often report a past or current pattern of illicit substance use and/or alcohol misuse. Still, little is known about the cumulative and separate effects of each stressor on white matter tissue, at this vulnerable period of brain development. Participants involved 24 healthy controls with a past or current history of sustained illicit drug use and/or alcohol misuse (users), 23 healthy controls without such history (normative data), and 27 users with early phase schizophrenia. (1)H-MRS data were acquired from a large frontal volume encompassing 95% of white matter, using a 4Tesla scanner (LASER sequence, TR/TE 3200/46ms). Reduced levels of choline-containing compounds (Cho) were specific to the effect of illness (Cohen's d=0.68), with 22% of the variance in Cho levels accounted for by duration of illness. Reduced levels of myoInositol (d=1.10) and creatine plus phosphocreatine (d=1.07) were specific to the effects of illness plus substance use. Effect of substance use on its own was revealed by reductions in levels of glutamate plus glutamine (d=0.83) in control users relative to normative data. The specific effect of illness on white matter might indicate a decreased synthesis of membrane phospholipids or alternatively, reduced membrane cellular density. In terms of limitations, this study did not include patients without a lifetime history of substance use (non-users), and the specific effect of each substance used could not be studied separately.

A meta-analysis of the association between substance use and emerging adult development using the IDEA scale.

PubMed

Davis, Jordan P; Dumas, Tara M; Briley, Daniel A; Sussman, Steve

Much debate exists surrounding Arnett's theory of emerging adulthood in terms of its breadth and application. Researchers have attempted to capture dimensions of emerging adulthood (eg, experimentation, negativity/instability, other-focus, self-focus, and feeling in-between) through self report assessment, using variations of the Inventory of the Dimensions of Emerging Adulthood or IDEA. Results from studies investigating this relationship have been mixed. We conducted a meta-analysis on the association between substance use and the IDEA. Data were extracted to calculate correlational associations with substance use as well as typical moderators found in the literature. Twelve studies were meta-analyzed. We found small associations (range: ρ = -.03 to .15; d = .06 to 30) between the IDEA scores and substance use. We found higher severity (dependence diagnosis) of participants yielded larger associations across all dimensions (ρ = .16), and proportion of college students to be a subscale-specific moderator (experimentation, negativity/instability, other-focus, self-focus, and feeling in-between). Alcohol use outcomes also provided larger subscale-specific associations (experimentation, negativity/instability, other-focus, self-focus). The dimensions of emerging adulthood may be less effective in predicting substance use among non-college samples and those studies focusing on drug use. Further research should prioritize exploring variation in the transition to emerging adulthood among non-college samples and the longitudinal associations between IDEA and substance use. Important contributions include the modest association between IDEA and substance use as well as specific participant characteristics that amplify or mitigate the association between IDEA and substance use.

Testing Gender Effects on the Mechanisms Explaining the Association between Post-Traumatic Stress Symptoms and Substance Use Frequency

Bornovalova, Marina A.; Ouimette, Paige; Crawford, Aaron V.; Levy, Roy

2009-01-01

The present study examines gender differences in the mechanisms that explain the association between PTSD symptoms and substance use frequency in a sample of 182 urban substance users. Specifically, the current study examined gender differences in the role of two potential explanatory variables, namely, difficulties controlling impulsive behavior when distressed (IMP), and a lack of emotional awareness and clarity (AW/CLAR). Multiple-group path modeling (across males and females) was used to examine gender differences in the path coefficients from PTSD symptoms to IMP and AW/CLAR, and from these latter variables to drug use frequency. Results indicated that PTSD symptoms were associated with IMP and AW/CLAR, and these path coefficients did not vary by gender. However, gender differences emerged when considering the path coefficients from AW/CLAR and IMP to substance use frequency. Specifically, for women, the association between PTSD and substance use was partially explained by IMP, whereas for men, the association between PTSD and substance use was partially explained by AW/CLAR. The current study is the first to examine gender differences in mechanisms accounting for the association between PTSD and substance use frequency, and these results also support the value and importance of examining gender differences in mechanisms underlying PTSD-SUD comorbidity.

Although the association between acculturation and substance use among Latino groups is important, it is often understudied, especially within specific Latino groups living in geographically distinct communities, such as the Mexican American population in South Texas. The researchers of this study aimed to better understand the effect of acculturation on substance use and alcohol dependence in a Mexican American college student population. This survey study investigated the correlation between acculturation and substance use and dependence by using the Vancouver Index of Acculturation (VIA), items related to substance use (nicotine, marijuana, and cocaine) in a Mexican American college student sample (N = 1,494), and the Short Alcohol Dependence Data Questionnaire (SADD; N = 715). The study was conducted in the Texas-Mexico border region. The results suggest that higher levels of acculturation do not predict increased drug use or alcohol dependence in the Mexican American college students. However, acculturation was found to be associated with lower use of cocaine and marijuana. The discussion examines commonalities and differences in drug use and dependence. Specifically, acculturation seems to have an inverse relationship to substance use and may serve as a protective factor to licit and illicit drug use among Mexican American college students.

Studies on the cellular localization of spinal cord substance P receptors.

PubMed

Helke, C J; Charlton, C G; Wiley, R G

1986-10-01

Substance P-immunoreactivity and specific substance P binding sites are present in the spinal cord. Receptor autoradiography showed the discrete localization of substance P binding sites in both sensory and motor regions of the spinal cord and functional studies suggested an important role for substance P receptor activation in autonomic outflow, nociception, respiration and somatic motor function. In the current studies, we investigated the cellular localization of substance P binding sites in rat spinal cord using light microscopic autoradiography combined with several lesioning techniques. Unilateral injections of the suicide transport agent, ricin, into the superior cervical ganglion reduced substance P binding and cholinesterase-stained preganglionic sympathetic neurons in the intermediolateral cell column. However, unilateral electrolytic lesions of ventral medullary substance P neurons which project to the intermediolateral cell column did not alter the density of substance P binding in the intermediolateral cell column. Likewise, 6-hydroxydopamine and 5,7-dihydroxytryptamine, which destroy noradrenergic and serotonergic nerve terminals, did not reduce the substance P binding in the intermediolateral cell column. It appears, therefore, that the substance P binding sites are located postsynaptically on preganglionic sympathetic neurons rather than presynaptically on substance P-immunoreactive processes (i.e. as autoreceptors) or on monoamine nerve terminals. Unilateral injections of ricin into the phrenic nerve resulted in the unilateral destruction of phrenic motor neurons in the cervical spinal cord and caused a marked reduction in the substance P binding in the nucleus. Likewise, sciatic nerve injections of ricin caused a loss of associated motor neurons in the lateral portion of the ventral horn of the lumbar spinal cord and a reduction in the substance P binding. Sciatic nerve injections of ricin also destroyed afferent nerves of the associated dorsal root ganglia and increased the density of substance P binding in the dorsal horn. Capsaicin, which destroys small diameter primary sensory neurons, similarly increased the substance P binding in the dorsal horn. These studies show that the cellular localization of substance P binding sites can be determined by analysis of changes in substance P binding to discrete regions of spinal cord after selective lesions of specific groups of neurons. The data show the presence of substance P binding sites on preganglionic sympathetic neurons in the intermediolateral cell column and on somatic motor neurons in the ventral horn, including the phrenic motor nucleus.(ABSTRACT TRUNCATED AT 400 WORDS)

Anxiety disorders and drug dependence: evidence on sequence and specificity among adults.

PubMed

Goodwin, Renee D; Stein, Dan J

2013-04-01

The goal of this study was to investigate the relation between specific anxiety disorders and substance dependence, adjusting for potentially confounding demographic factors (e.g. sex) and comorbidity (e.g. alcohol dependence, major depression), among adults in the USA. Data were drawn from the National Comorbidity Survey (NCS), a nationally representative population sample of the US adult population aged 15-54. The temporal sequence of onset of anxiety and substance dependence disorders was examined. Substance dependence temporally precedes several anxiety disorders, particularly panic disorder. Specifically, a history of past substance dependence predicts current panic disorder (odds ratio [OR] =2.62, 95% confidence interval [CI] =1.29, 5.32), social phobia (OR=1.7, 95%CI=1.12, 2.41), and agoraphobia (OR=1.78, 95%CI=1.08, 2.94). Conversely, in more than 50% of substance abuse disorder cases, in nearly 40% of post-traumatic stress disorder (PTSD) cases, and in nearly 30% of generalized anxiety disorder (GAD) cases, the anxiety disorder has first onset. Similarly, a lifetime history of social phobia, PTSD, or GAD significantly predicts lifetime substance dependence (OR=1.51 for social phobia, 2.06 for PTSD, 1.45 for GAD). For any particular anxiety disorder, a diagnosis of substance abuse can occur prior to or subsequent to an anxiety disorder. Nevertheless, there is also evidence for the specificity of some associations between anxiety and substance dependence disorders; these are independent of the effects of sex and other comorbid disorders, may be causal in nature, and deserve particular attention in clinical settings. The possibility that within a particular anxiety disorder there are a variety of mechanisms of association with various substances should be addressed in future work. © 2013 The Authors.

Screening adolescents for substance use and intervening immediately can reduce the burden of addiction and substance-related morbidity. Several screening tools have been developed to identify problem substance use for adolescents, but none have been calibrated to triage adolescents into clinically relevant risk categories to guide interventions. To describe the psychometric properties of an electronic screen and brief assessment tool that triages adolescents into 4 actionable categories regarding their experience with nontobacco substance use. Adolescent patients (age range, 12-17 years) arriving for routine medical care at 2 outpatient primary care centers and 1 outpatient center for substance use treatment at a pediatric hospital completed an electronic screening tool from June 1, 2012, through March 31, 2013, that consisted of a question on the frequency of using 8 types of drugs in the past year (Screening to Brief Intervention). Additional questions assessed severity of any past-year substance use. Patients completed a structured diagnostic interview (Composite International Diagnostic Interview-Substance Abuse Module), yielding Diagnostic and Statistical Manual of Mental Disorders (Fifth Edition) substance use diagnoses. For the entire screen and the Screening to Brief Intervention, sensitivity and specificity for identifying nontobacco substance use, substance use disorders, severe substance use disorders, and tobacco dependence were calculated using the Composite International Diagnostic Interview-Substance Abuse Module as the criterion standard. Of 340 patients invited to participate, 216 (63.5%) enrolled in the study. Sensitivity and specificity were 100% and 84% (95% CI, 76%-89%) for identifying nontobacco substance use, 90% (95% CI, 77%-96%) and 94% (95% CI, 89%-96%) for substance use disorders, 100% and 94% (95% CI, 90%-96%) for severe substance use disorders, and 75% (95% CI, 52%-89%) and 98% (95% CI, 95%-100%) for nicotine dependence. No significant differences were found in sensitivity or specificity between the full tool and the Screening to Brief Intervention. A single screening question assessing past-year frequency use for 8 commonly misused categories of substances appears to be a valid method for discriminating among clinically relevant risk categories of adolescent substance use.

IMPORTANCE Screening adolescents for substance use and intervening immediately can reduce the burden of addiction and substance-related morbidity. Several screening tools have been developed to identify problem substance use for adolescents, but none have been calibrated to triage adolescents into clinically relevant risk categories to guide interventions. OBJECTIVE To describe the psychometric properties of an electronic screen and brief assessment tool that triages adolescents into 4 actionable categories regarding their experience with nontobacco substance use. DESIGN, SETTING, AND PARTICIPANTS Adolescent patients (age range, 12–17 years) arriving for routine medical care at 2 outpatient primary care centers and 1 outpatient center for substance use treatment at a pediatric hospital completed an electronic screening tool from June 1, 2012, through March 31, 2013, that consisted of a question on the frequency of using 8 types of drugs in the past year (Screening to Brief Intervention). Additional questions assessed severity of any past-year substance use. Patients completed a structured diagnostic interview (Composite International Diagnostic Interview–Substance Abuse Module), yielding Diagnostic and Statistical Manual of Mental Disorders (Fifth Edition) substance use diagnoses. MAIN OUTCOMES AND MEASURES For the entire screen and the Screening to Brief Intervention, sensitivity and specificity for identifying nontobacco substance use, substance use disorders, severe substance use disorders, and tobacco dependence were calculated using the Composite International Diagnostic Interview–Substance Abuse Module as the criterion standard. RESULTS Of 340 patients invited to participate, 216 (63.5%) enrolled in the study. Sensitivity and specificity were 100% and 84%(95%CI, 76%–89%) for identifying nontobacco substance use, 90% (95%CI, 77%–96%) and 94%(95%CI, 89%–96%) for substance use disorders, 100% and 94%(95%CI, 90%–96%) for severe substance use disorders, and 75% (95%CI, 52%–89%) and 98%(95%CI, 95%–100%) for nicotine dependence. No significant differences were found in sensitivity or specificity between the full tool and the Screening to Brief Intervention. CONCLUSIONS AND RELEVANCE A single screening question assessing past-year frequency use for 8 commonly misused categories of substances appears to be a valid method for discriminating among clinically relevant risk categories of adolescent substance use.

2018-06-01

The current study aimed to understand whether substance-specific parenting practices predicted the probability of child alcohol, cigarette, or marijuana use beyond known family factors like family management and parental substance use and norms. Data were drawn from the Intergenerational Project, which used an accelerated longitudinal design and included 383 families surveyed seven times between 2002 and 2011. Analyses included 224 families with children ages 10-18 years (49% female). Multilevel models tested both concurrent and lagged (predictors at time t - 1, outcomes at time t) associations between child past year use of alcohol, cigarettes, and marijuana and time-varying measures of substance-specific parenting practices, including permitting child use of alcohol or cigarettes; family rules about alcohol, cigarette, and drug use; and child involvement in family member alcohol or cigarette use (getting, opening, or pouring alcoholic drinks; getting or lighting cigarettes for family members). Demographic controls were included. Child involvement in family member substance use predicted an increased probability of child substance use both concurrently and 1 year later, even when controlling parent substance use, pro-substance norms, and family management. Family rules about substance use and parent provision of alcohol or cigarettes were not consistently related to child alcohol, cigarette, or marijuana use. Family-based preventive interventions to reduce youth substance use should continue to focus on family management and include messaging discouraging parents from allowing children to get, open, or pour drinks or get or light cigarettes for family members.

The article deals with the issue of improving fuel efficiency and the ecological nature of passenger cars, servicing the administrative and management personnel of the oil and gas complex. It is established that fuel consumption and the amount of specific emissions of harmful substances with exhaust gases of cars when using the “climate control” system depend on the effective ambient temperature, the color of the opaque car body elements, the power of the car engine and the interior volume. However, the simplest controlled factor is the color of the opaque car body elements, which is characterized by the coefficient of light reflection. In the course of experimental studies, the authors established the dependences of a change in fuel consumption and a share of reducing emissions of harmful substances with exhaust gases of passenger cars with the “climate control” system on the coefficient of light reflection. A method has been developed to reduce fuel consumption and the amount of specific emissions of harmful substances with the exhaust gases of passenger cars using the “climate control” system, which involves painting the vehicle roof white and allows reducing fuel consumption by 5.5-10.3%, and the amount of specific emissions of harmful substances by 0.8-2.3%.

Substance abuse and criminal thinking: testing the countervailing, mediation, and specificity hypotheses.

PubMed

Walters, Glenn D

2012-12-01

The purpose of this study was to determine (a) which of 2 dimensions of criminal thinking (proactive and/or reactive) correlates with prior substance abuse; (b) whether criminal thinking mediates the relationship between prior substance abuse and recidivism; (c) if a direct relationship exists between specific drugs of abuse and specific criminal thinking styles. First, the reconstructed Proactive (Prc) and Reactive (Rrc) Criminal Thinking scores from the Psychological Inventory of Criminal Thinking Styles (PICTS; Walters, 1995) were correlated with a dichotomous measure of prior substance abuse and a continuous measure of the number of substances abused in a sample of 2877 male federal prisoners (age: M = 34.96, SD = 9.89, range = 18-84; race: 63.6% Black, 17.3% White, 17.6% Hispanic, 1.4% other). The results indicated that only the Rrc score correlated significantly with prior substance abuse when the effect of the alternative measure (Prc in the case of Rrc and Rrc in the case of the Prc) was controlled through partial correlations. Second, reactive criminal thinking was found to mediate the relationship between a history of prior substance abuse and subsequent recidivism in a subsample of 1101 inmates who were released from prison during a 1- to 76-month follow-up. Third, both specific (alcohol with cutoff; marijuana with cognitive indolence) and global (heroin, cocaine, and amphetamine with cutoff, cognitive indolence, and discontinuity) drug-criminal thinking correlations were obtained. These results suggest that reactive criminal thinking plays a potentially important role in the drug-crime relationship.

Association Between Substance Use and Gun-Related Behaviors

Chen, Danhong; Wu, Li-Tzy

2016-01-01

Gun-related violence is a public health concern. This study synthesizes findings on associations between substance use and gun-related behaviors. Searches through PubMed, Embase, and PsycINFO located 66 studies published in English between 1992 and 2014. Most studies found a significant bivariate association between substance use and increased odds of gun-related behaviors. However, their association after adjustment was mixed, which could be attributed to a number of factors such as variations in definitions of substance use and gun activity, study design, sample demographics, and the specific covariates considered. Fewer studies identified a significant association between substance use and gun access/possession than other gun activities. The significant association between nonsubstance covariates (e.g., demographic covariates and other behavioral risk factors) and gun-related behaviors might have moderated the association between substance use and gun activities. Particularly, the strength of association between substance use and gun activities tended to reduce appreciably or to become nonsignificant after adjustment for mental disorders. Some studies indicated a positive association between the frequency of substance use and the odds of engaging in gun-related behaviors. Overall, the results suggest a need to consider substance use in research and prevention programs for gun-related violence. PMID:26769722

Prior studies, utilizing interview-based assessments, suggest that most of the genetic risk factors for drug abuse (DA) are non-specific with a minority acting specifically on risk for abuse of particular psychoactive substance classes. We seek to replicate these findings using objective national registry data. We examined abuse of cannabis, stimulants (including cocaine) and sedatives ascertained from national Swedish registers in male-male monozygotic (1720 pairs) and dizygotic twins (1219 pairs) combined with near-age full siblings (76,457 pairs) to provide sufficient power. Modeling was performed using Mx. A common pathway model fitted better than an independent pathway model. The latent liability to DA was highly heritable but also influenced by shared environment. Cannabis, stimulant and sedative abuse all loaded strongly on the common factor. Estimates for the total heritability for the three forms of substance abuse ranged from 64 to 70%. Between 75 and 90% of that genetic risk was non-specific, coming from the common factor with the remainder deriving from substance specific genetic risk factors. By contrast, all of the shared environmental effects, which accounted for 18-20% of the variance in liability, were non-specific. In accord with prior studies based on personal interviews, the large preponderance of genetic risk factors for abuse of specific classes of psychoactive substance are non-specific. These results suggest that genetic variation in the primary sites of action of the psychoactive drugs, which differ widely across most drug classes, play a minor role in human individual differences in risk for DA.

Tatalović Vorkapić, Sanja; Mustapić, Jelena

2012-01-01

In this study, burnout and its internal and external factors were investigated among substance abuse counsellors (no. = 68) who worked in Centres for Prevention and Substance Abuse Treatment (no. = 18) in Croatia. Maslach Burnout Inventory was used which measured three burnout dimensions: emotional exhaustion, depersonalization and personal accomplishment; and questionnaire of internal and external burnout factors. The higher levels of emotional exhaustion and depersonalization, and the higher level of personal accomplishment were determined. Factors such as work conditions, emotions about us and work, work organization and certain personality traits showed significant relationship with three burnout dimensions. Overall, findings implicated a certain specificity of professional burnout in substance abuse counsellors, and the need for specific design of mental health care for them.

Rule breaking mediates the developmental association between GABRA2 and adolescent substance abuse.

This study's primary aim was to examine age-specific associations between GABRA2, rule breaking, problematic alcohol use, and substance abuse symptomatology. The secondary aim was to examine the extent to which rule breaking mediates the GABRA2-substance abuse relationship. A sample (n = 518) of primarily male (70.9%) and White (88.8%) adolescents from the Michigan Longitudinal Study was assessed from ages 11-18. Age-specific effects of GABRA2 on rule breaking, problematic alcohol use, and substance abuse symptomatology were examined using nested path models. The role of rule breaking as a mediator in the association between GABRA2 and substance abuse outcomes was tested using prospective cross-lagged path models. GABRA2 is significantly (p < 0.05) associated with rule breaking in mid- to late-adolescence, but not substance abuse symptomatology across adolescence. GABRA2 effects on problematic alcohol use and substance abuse symptomatology operate largely (45.3% and 71.1%, respectively, p < 0.05) via rule breaking in midadolescence. GABRA2 represents an early risk factor for an externalizing pathway to the development of problematic alcohol and drug use. © 2014 The Authors.

2010-05-01

The purpose of this study was to investigate gender-specific variations in the associations between communication with father and mother, cigarette smoking, alcohol drinking and marijuana use in male and female adolescents. Cross-sectional data were collected from a national sample of 1308 tenth graders who participated in the 2005/06 U.S. HBSC. Outcome variables were self-reported substances used in the past 30 days. Logistic regression analyses controlling for race/ethnicity, family structure and socioeconomic status showed that the association of mother and father communication with adolescent substance use varied by substance and gender. Among sons, father communication was protective against marijuana use and mother communication was protective against smoking. Neither father nor mother communication was protective against substance use by daughters. Research is needed to understand gender-specific differences in correlates of adolescent substance use and the implications for prevention and intervention. Copyright (c) 2009 Elsevier Ltd.

Håkansson, Anders; Jesionowska, Virginia

2018-01-01

The present study aimed to study the associations between substance use patterns and types of crimes in prisoners with substance use problems, and specifically whether substance use patterns were different in violent offenders. Interview data of prisoners with substance use problems (N=4,202, mean age 33.5 years, SD 9.8), derived from the Addiction Severity Index, were run against criminal register data on main types of crimes in the verdict. In binary analyses, compared to those with acquisitive and drug crimes, violent offenders had lower prevalence of illicit drugs and homelessness, but higher prevalence of binge drinking, and higher prevalence of sedative use than clients sentenced with drug crimes. Clients with violent crime had lower prevalence of injecting drug use, compared to all other crimes. In logistic regression, binge drinking and sedatives were positively associated with violent crime (as opposed to non-violent crime), whereas heroin, amphetamine, cocaine, and injecting drug use were negatively associated with violent crime. Among violent offenders only, sedatives tended to be associated with fatal violence ( p =0.06), whereas amphetamine, homelessness, age, and (marginally significant, p =0.05) heroin were negatively associated with fatal violence, as opposed to non-fatal violence. Treatment and risk assessment in violent perpetrators with substance use may need to address sedatives and alcohol specifically. Limitations of the study are due to self-reported and cross-sectional data and because a large majority of the prison sample studied here are men.

Substance use and violent behavior in women with antisocial personality disorder.

PubMed

Lewis, Catherine F

2011-01-01

The purpose of this study was to examine the relationship between substance abuse and dependence and violent behavior in a sample of incarcerated women with antisocial personality disorder (ASPD). Among male populations, substance dependence is associated with aggression and criminal behavior. Individuals with ASPD have more severe substance dependence, including higher symptom counts, earlier age of onset, and more frequent co-morbidity. Incarcerated women have a high prevalence of ASPD and substance dependence, but there has been little detailed work regarding addiction severity. Similarly, work on association of substance abuse and dependence with specific violent behaviors has been limited. This study examined a group of 41 mid-sentence female felons with a diagnosis of ASPD to determine associations with substance abuse and dependence. Data were gathered through administration of the Semi-Structured Assessment of the Genetics of Alcoholism II (SSAGA II). Substance dependence was highly prevalent (i.e., alcohol dependence, 56.1%; opiate dependence, 48.8%; cocaine dependence, 61.0%). While specific diagnoses were not associated with violent behavior and offending, symptom severity (i.e., age of onset, symptom count, co-morbidity) was associated with violent behavior in women dependent on opiates, alcohol, and cocaine. Arrest for an assault 1 was associated with alcohol dependence and opiate dependence. These data suggest that measurement of symptom severity and co-morbidity is important in assessing violent behavior in incarcerated women with ASPD. These findings are potentially important in examining non-incarcerated, substance-dependent women. Copyright © 2011 John Wiley & Sons, Ltd.

This study examined whether duration of unemployment from ages 21 to 33 was associated with symptoms of alcohol use disorder, nicotine dependence disorder, and cannabis use disorder at age 39, after accounting for childhood and early adult involvement in substance use and other indicators of psychopathology. Analyses also investigated whether dimensions of perceived neighborhood characteristics during childhood and adolescence contributed to the link between unemployment and substance use disorder symptoms during adulthood. Potential gender differences were examined. Using life-course calendar data from a prospective longitudinal study (N=677), participants' unemployment history was measured from ages 21 to 33. General childhood and substance use-specific neighborhood characteristics were assessed at ages 10-18. Findings from negative binomial regression models showed that duration of unemployment was associated with higher levels of alcohol use disorder and nicotine dependence symptoms, after adjusting for earlier involvement in substance use. Substance use-specific neighborhood factors during childhood were associated with symptoms of nicotine dependence and cannabis use disorder. Findings also suggest that the detrimental impact of unemployment on nicotine dependence symptoms was possibly stronger for women. Findings suggest that unemployment may be an important risk factor for alcohol use disorder and nicotine dependence symptoms, indicating that public health efforts providing strategies to cope with unemployment, particularly for women who experience chronic unemployment, may be promising. Additionally, substance use-specific neighborhood characteristics during childhood should be considered as part of a prevention strategy to ameliorate adult nicotine and cannabis use problems.

Trucco, Elisa M.; Hicks, Brian M.; Villafuerte, Sandra; Nigg, Joel; Burmeister, Margit; Zucker, Robert A.

2016-01-01

Understanding how specific genes contribute to risk for addiction remains challenging. This study tests whether childhood temperament and externalizing behavior in early adolescence account for a portion of the association between specific genetic variants and substance use problems in late adolescence. The sample consisted of 487 adolescents from the Michigan Longitudinal Study, a high-risk sample (70.2% male, 81.7% European American ancestry). Polymorphisms across serotonergic (SLC6A4, 5-HTTLPR), dopaminergic (DRD4, u-VNTR), noradrenergic (SLC6A2, rs36021), and GABAergic (GABRA2, rs279858; GABRA6, rs3811995) genes were examined given prior support for associations with temperament, externalizing behavior, and substance use problems. The temperament traits behavioral control and resiliency were assessed using interviewer ratings (ages 9-11), and externalizing behavior (ages 12-14) was assessed using teacher ratings. Self-reported substance use outcomes (ages 15-17) included maximum alcoholic beverages consumed in 24 hours, and frequency of past year cigarette and marijuana use. Behavioral control, resiliency, and externalizing behavior accounted for the associations between polymorphisms in noradrenergic and GABAergic genes and substance use in late adolescence. Individual differences in emotional coping and behavioral regulation represent non-specific neurobiological underpinnings for an externalizing pathway to addiction. PMID:26845260

Risk of inpatient stay for mental illness among individuals with substance use disorders.

PubMed

Prince, Jonathan D

2012-09-01

Whereas most studies of inpatient stay for mental illness examine whether substance use is present, this study identified types or combinations of abused substances that most increased hospitalization risk. Logistic regression of data from the 2007 National Survey of Drug Use and Health (N=37,654) was used to predict past-year hospitalization of individuals with DSM-IV substance use disorders. Even after the inclusion of control variables, adults with four types of substance abuse or dependence were more likely to be hospitalized than adults without substance abuse or dependence. High-risk disorders included abuse of or dependence on opioid analgesics (odds ratio [OR]=6.85, p<.001), cocaine (OR=2.65, p<.05), alcohol and cocaine (OR=2.58, p<.05), and alcohol and marijuana (OR=3.10, p<.01). Researchers examining inpatient stays may find it beneficial to look at abuse of specific substances or combinations of substances, and efforts to prevent inpatient stays could target people with high-risk substance use disorders.

Substance use capital: Social resources enhancing youth substance use.

PubMed

Baggio, S; Mohler-Kuo, M; Dupuis, M; Henchoz, Y; Studer, J; N'Goran, A A; Gmel, G

2016-09-01

Social capital is described as a protective factor against youth substance use, but it may also be associated with behaviours that do not enhance health. The present study hypothesized that 'substance use capital', i.e. resources favourable to substance use, is a risk factor for substance use and misuse. We used baseline data from the ongoing Cohort Study on Substance Use Risk Factors (C-SURF) that included a representative sample of young Swiss men (n=5623). Substance use (alcohol, cannabis, 15 illicit drugs, lifetime use, hazardous use and dependence), substance use capital (parental and peer attitudes towards substance use, parental and peer drug use, perceived norms of substance use) and aspects of social capital (relationships with parents and peers) were assessed. Logistic regressions were used to examine the associations between substance-related resources and social resources, and substance use. Results showed that substance-related resources were associated with an increased risk of substance use (OR between 1.25 and 4.67), whereas social resources' associations with substance use were commonly protective but weaker than substance-related resources. Thus, a drug-friendly environment facilitated substance use and misuse. Moreover, the results showed that peer environments were more drug-friendly than familial environments. In conclusion, this study highlighted a concept of 'substance use capital', which may be useful for advancing both theoretical and applied knowledge of substance use. Indeed, substance use is not only associated with a lack of social resources, but also with specific drug-friendly social resources coming from environment and background.

Mechanism of action of substance P in guinea-pig ileum longitudinal smooth muscle: a re-evaluation.

PubMed Central

Hall, J M; Morton, I K

1990-01-01

1. A proposed mechanism of contractile action of substance P in guinea-pig ileum longitudinal smooth muscle involving a decrease in membrane K+ permeability (PK) has been re-examined. 2. Potentiation of responses to substance P by the K+ channel blocker tetraethylammonium (TEA) was originally proposed as evidence for a mechanism of action of substance P involving a decrease in PK. Potentiation was confirmed; however this was found not to be specific to substance P since a similar potentiation of responses was seen with agonists not thought to act via a decrease in PK. 3. Antagonism of contractile responses to substance P by noradrenaline was similarly confirmed. However, this antagonism was found to represent a non-specific functional interaction through the inhibitory actions of beta-adrenoceptors rather than the proposed specific interaction with an increase in PK by noradrenaline which is normally alpha 1-adrenoceptor mediated. 4. Experiments were made measuring 86Rb efflux, in depolarized guinea-pig ileum longitudinal smooth muscle, to estimate PK. These studies confirmed a reported decrease in PK with TEA, but failed to detect the previously reported decrease with substance P. 5. These results, although not disproving a suggested mechanism of direct contractile action of substance P in guinea-pig ileum longitudinal smooth muscle involving a decrease in PK, do throw doubt on either the evidence, or its interpretation, as proposed by the original authors in support of such a mechanism.

The abstinence phobias: links between substance abuse and anxiety.

PubMed

Hall, S M

1984-09-01

This paper presents a new model to explain the observed relationship between anxiety and substance abuse. Specifically, the concept of "abstinence phobias," common across psychoactive substances, is developed. The evidence needed to support this concept is outlined, and relevant data from studies of opiate, alcohol, and tobacco dependences are reviewed. Parallel data obtained from the treatment of obesity are discussed. It is concluded that the abstinence phobia merits further study; clinical implications are also considered.

A Framework for Conducting a National Study of Substance Abuse Treatment Programs Serving American Indian and Alaska Native Communities

Background Because of their broad geographic distribution, diverse ownership and operation, and funding instability, it is a challenge to develop a framework for studying substance abuse treatment programs serving American Indian and Alaska Native communities at a national level. This is further complicated by the historic reluctance of American Indian and Alaska Native communities to participate in research. Objectives and Methods We developed a framework for studying these substance abuse treatment programs (n = 293) at a national level as part of a study of attitudes toward, and use of, evidence-based treatments among substance abuse treatment programs serving AI/AN communities with the goal of assuring participation of a broad array of programs and the communities that they serve. Results Because of the complexities of identifying specific substance abuse treatment programs, the sampling framework divides these programs into strata based on the American Indian and Alaska Native communities that they serve: (1) the 20 largest tribes (by population); (2) urban AI/AN clinics; (3) Alaska Native Health Corporations; (4) other Tribes; and (5) other regional programs unaffiliated with a specific AI/AN community. In addition, the recruitment framework was designed to be sensitive to likely concerns about participating in research. Conclusion and Scientific Significance This systematic approach for studying substance abuse and other clinical programs serving AI/AN communities assures the participation of diverse AI/AN programs and communities and may be useful in designing similar national studies.

The purpose of this study was to evaluate the effectiveness of outpatient substance abuse treatment for youth with high traumatic stress compared to youth without high traumatic stress in substance abuse treatment centers across the United States. The data for this study were gathered using a longitudinal survey design with purposive sampling from nine drug treatment delivery systems across the United States participating in the cooperative grant Strengthening Communities for Youth (SCY) awarded by SAMHSA's Center for Substance Abuse Treatment (CSAT) between September 2002 and June 2006. Follow-up assessments were conducted with the youth at three,six, and 12 months following intake. Traumatized youth responded to outpatient treatment in a similar pattern when compared to nontraumatized youth, although the traumatized youth had consistently higher scores on substance use frequency and substance problems scales than nontraumatized youth throughout the study. Current empirically validated treatments for adolescent substance abuse do not prepare the practitioner for trauma-informed practice or specifically address trauma-informed recovery. Based on our results, we advocate for the development and integration of trauma-informed practice within substance abuse treatment for adolescents to help them recover from trauma and substance abuse issues.

High rates of substance use and related problems have been long recognized as critical health issues for Native American adolescents. Unfortunately, no manualized interventions address the specific needs of Native American adolescents in a culturally appropriate manner. In 2006, the Cherokee Nation partnered with the University of Colorado to employ a community-based participatory research process to develop an intervention for Native American adolescents with substance use problems. The resulting intervention, Walking On, is an explicit blend of traditional Cherokee healing and spirituality with science-based practices such as cognitive behavioral therapy and contingency management and is designed to address the specific needs and worldviews of Native American adolescents with substance use problems and their families. Each individual and family session includes a brief assessment, a skill-building component, and a ceremony. A Weekly Circle (multifamily group) promotes sobriety and builds a community of healing. Early pilot study results suggest that Walking On is feasible for use in tribal substance abuse treatment programs. While Walking On shows early promise, the intervention will require further study to examine its efficacy.

Anhedonia in substance use disorders: a systematic review of its nature, course and clinical correlates.

PubMed

Garfield, Joshua B B; Lubman, Dan I; Yücel, Murat

2014-01-01

There is growing evidence that anhedonia is a commonly experienced symptom among substance-using populations. This systematic review synthesises findings across a range of substances to address questions regarding the time course of anhedonia, how anhedonia relates to other symptoms of substance dependence and whether it is similarly prevalent across all addictive drugs. A literature search was conducted on PubMed, PsycINFO and MEDLINE, yielding 32 studies that used self-report measures of anhedonia among participants with a history of a substance abuse, dependence or long-term daily use of addictive substances. Findings from these studies indicate that anhedonia (1) is elevated in samples dependent on a range of substances; (2) typically appears as a consequence of substance abuse or dependence, and diminishes with abstinence; and (3) predicts increased drug cravings and the likelihood of relapse in those attempting abstinence. The common experience of anhedonia in substance-dependent populations, and its relationship to relapse, emphasises the importance of developing therapeutic interventions that specifically target anhedonia in the treatment of all substance use disorders.

Two cross-sectional studies investigated media influences on adolescents' substance use and intentions to use substances in the context of exposure to parental and peer risk and protective factors. A total of 729 middle school students (n = 351, 59% female in Study 1; n = 378, 43% female in Study 2) completed self-report questionnaires. The sample in Study 1 was primarily African-American (52%) and the sample in Study 2 was primarily Caucasian (63%). Across the two studies, blocks of media-related cognitions made unique contributions to the prediction of adolescents' current substance use and intentions to use substances in the future above and beyond self-reported peer and parental influences. Specifically, identification with and perceived similarity to media messages were positively associated with adolescents' current substance use and intentions to use substances in the future, and critical thinking about media messages and media message deconstruction skills were negatively associated with adolescents' intention to use substances in the future. Further, peer influence variables (e.g., peer pressure, social norms, peer substance use) acted as risk factors, and for the most part, parental influence variables (e.g., parental pressure to not use, perceived parental reaction) acted as protective factors. These findings highlight the importance of developing an increased understanding of the role of media messages and media literacy education in the prevention of substance use behaviors in adolescence.

Objectives Research suggests that individual and environmental resilience protective factors may be associated with adolescent substance use; however, the associations between a broad range of such factors and use of various types of substances have not been examined. The study aimed to determine the association between a comprehensive range of adolescent individual and environmental resilience protective factors and measures of tobacco, alcohol and illicit substance use. Design Cross-sectional study. Setting 32 Australian secondary schools. Participants Grade 7–10 students (aged 11–17 years). Measures Data regarding 14 student individual and environmental resilience protective factors and seven substance use measures (tobacco, alcohol, marijuana, other illicit drug use) were obtained via an online self-report survey. Adjusted multivariate logistic regression analyses examined the association between all student resilience protective factors and seven substance use measures. Results Inverse univariate associations were found for 94 of 98 relationships examined (n=10 092). Multivariate analyses found: consistent inverse associations between 2 of 14 protective factors and all substance use measures (‘goals and aspirations’, ‘prosocial peers’); inverse associations between 4 protective factors with multiple substance use measures (‘home support’ (5 of 7), ‘school support’ (3 of 7), ‘self-awareness’ (2 of 7), ‘community meaningful participation’ (2 of 7)); positive associations between 2 resilience protective factors with multiple measures of substance use (‘community support’ (3 of 7), ‘peer caring relationships’ (5 of 7)) and 6 protective factors not to be associated with any substance use measure. Conclusions Despite individual relationships between the majority of resilience protective factors and substance use types, the protective benefit of such factors for adolescent substance use was limited to only a small number of such factors when considered collectively. Such results suggest that interventions seeking to reduce adolescent substance use may need to target specific protective factors to address specific types of substance use.

2017-01-01

Substance addiction (or drug addiction) is a neuropsychiatric disorder characterized by a recurring desire to continue taking the drug despite harmful consequences. Non-substance addiction (or behavioral addiction) covers pathological gambling, food addiction, internet addiction, and mobile phone addiction. Their definition is similar to drug addiction but they differ from each other in specific domains. This review aims to provide a brief overview of past and current definitions of substance and non-substance addiction, and also touches on the topic of diagnosing drug addiction and non-drug addiction, ultimately aiming to further the understanding of the key concepts needed for a foundation to study the biological and psychological underpinnings of addiction disorders.

Substance P is known to exert potent effects in peripheral tissues, and is thought to be important for ocular function. The mechanism of action of substance P in the human eye is not known. As a basis for biochemical characterization specific binding of {sup 125}I-Bolton-Hunter-substance P was demonstrated in the human eye using autoradiographic methods. Biochemical characterization on slide-mounted tissue preparations showed that binding was saturable with a KD of 0.27 +/- 0.1 nmol/l. Specific binding occurred at comparable autoradiographic densities to both human retina and choroid. Substance P and its carboxyterminal fragment, substance P(3-11), were shown to be highlymore » potent in binding competition experiments against {sup 125}I-Bolton-Hunter-substance P. Similar concentrations of substance P(1-9), neurokinin A and neurokinin B failed to significantly alter specific binding of {sup 125}I-Bolton-Hunter-substance P. The results indicate expression of high affinity substance P binding sites in human retina and choroid.« less

Neuroimaging studies have demonstrated gray matter (GM) volume abnormalities in substance users. While the majority of substance users are polysubstance users, very little is known about the relation between GM volume abnormalities and polysubstance use. In this study we assessed the relation between GM volume, and the use of alcohol, tobacco, cocaine and cannabis as well as the total number of substances used, in a sample of 169 males: 15 non-substance users, 89 moderate drinkers, 27 moderate drinkers who also smoke tobacco, 13 moderate drinkers who also smoke tobacco and use cocaine, 10 heavy drinkers who smoke tobacco and use cocaine and 15 heavy drinkers who smoke tobacco, cannabis and use cocaine. Regression analyses showed that there was a negative relation between the number of substances used and volume of the dorsal medial prefrontal cortex (mPFC) and the ventral mPFC. Without controlling for the use of other substances, the volume of the dorsal mPFC was negatively associated with the use of alcohol, tobacco, and cocaine. After controlling for the use of other substances, a negative relation was found between tobacco and cocaine and volume of the thalami and ventrolateral PFC, respectively. These findings indicate that mPFC alterations may not be substance-specific, but rather related to the number of substances used, whereas, thalamic and ventrolateral PFC pathology is specifically associated with tobacco and cocaine use, respectively. These findings are important, as the differential alterations in GM volume may underlie different cognitive deficits associated with substance use disorders. Copyright © 2018 Elsevier B.V.

2014-01-01

Adults with attention-deficit/hyperactivity disorder (ADHD) are at higher risk to use substances than their nonclinical peers. Increased levels of impulsivity are generally thought to contribute to their increased levels of risk. Impulsivity is a multifaceted construct, however, and little research to date has attempted to identify which facets of impulsivity contribute to the increased rates of substance abuse among individuals with ADHD. The current study examined the relation among ADHD symptom clusters (i.e., hyperactivity/impulsivity and inattention), substance use rates (i.e., alcohol use, nicotine use, and marijuana use), and personality processes associated with impulsive behavior in a group of young adults. Participants were 361 undergraduate students. Both symptom clusters were positively associated with rates of substance use. Specifically, hyperactive/impulsive symptoms were associated with alcohol and nicotine use, and inattentive symptoms were associated with alcohol use. Several pathways from hyperactive/impulsive symptoms to alcohol, nicotine, and marijuana use via specific facets of impulsivity were identified. These findings have implications for understanding the relation between ADHD symptoms and substance use, as well as clinical implications for preventing and treating substance use problems in individuals with symptoms of ADHD.

2016-01-01

Depression is a highly heterogeneous condition, and identifying how symptoms present in various groups may greatly increase our understanding of its etiology. Importantly, Major Depressive Disorder is strongly linked with Substance Use Disorders, which may ameliorate or exacerbate specific depression symptoms. It is therefore quite plausible that depression may present with different symptom profiles depending on an individual's substance use status. Given these observations, it is important to examine the underlying construct of depression in groups of substance users compared to non-users. In this study we use a non-clinical sample to examine the measurement structure of the Beck Depression Inventory (BDI-II) in non-users and frequent-users of various substances. Specifically, measurement invariance was examined across those who do vs. do not use alcohol, nicotine, and cannabis. Results indicate strict factorial invariance across non-users and frequent-users of alcohol and cannabis, and metric invariance across non-users and frequent-users of nicotine. This implies that the factor structure of the BDI-II is similar across all substance use groups.

Substance abuse treatment in persons with HIV/AIDS: challenges in managing triple diagnosis.

PubMed

Durvasula, Ramani; Miller, Theodore R

2014-01-01

Clinical management of HIV must account for the "triple diagnosis" of HIV, psychiatric diagnosis, and substance use disorders and requires integrated treatment services that focus beyond just mitigation of substance use and psychiatric and medical symptoms but also address other health behaviors. Because clinical management of HIV/AIDS has shifted significantly with the advent of highly active antiretroviral therapies (HAART) in the mid 1990s, a literature review focusing on literature published since 2000, and using relevant key words was conducted using a wide range of literature search databases. This literature review was complemented by studies to expand on specific treatment modalities for which there was a dearth of literature addressing HIV infected cohorts and to provide discussion of issues around substance abuse treatment as an HIV prevention tool. Existing models of substance abuse treatment including cognitive behavioral therapy and motivational interviewing have proven to be useful for enhancing adherence and reducing substance use in outpatient populations, while methadone maintenance and directly observed treatment have been useful with specific subgroups of users. Contextualization of services heightens the likelihood of successful outcomes and relapse prevention.

Research on substance use and misuse in Lebanon is scarce and, when available, focuses on a specific substance or a limited segment of the population. The objective of this Rapid Situation Assessment (RAS) study was to survey the use of multiple substances in diverse segments of the Lebanese population. A multi-method and multi-sample survey was conducted to collect quantitative and qualitative data from the academic sector (high school and university students), substance users in treatment or under arrest (prison, detention), and non-institutionalized "street" users. Age of first use of substances started as early as 9 years in the youth sample. Moreover, 12% of the high school students reported smoking one or more packs of cigarettes per day and 9% of the university students met criteria for DSM-IV alcohol abuse. Cannabis represented the most commonly used illicit drug in both high school and university students, and tranquilizers were the most frequently misused medicinal substance. Heroin was responsible for 50% of the treatment admissions, followed by cocaine (20%), and alcohol (20%); heroin was also the most common substance of arrest. Recidivism was almost the rule for heroin users across all treatment settings. Unperceived need for treatment was the most common reason for not seeking treatment in non-institutionalized drug users (47.6%). Injecting drug use was a common behavior noted within substance using populations, in treatment and non-institutionalized (about 50% of them), with a high rate of needle sharing practices. About half of all patients in treatment had a history of police arrests, and about one-third of those in prison ever received prior treatment for substance use. The study points towards a growing trend for substance use problems in early adolescence that warrants close monitoring. Further investigation of these patterns is needed since the Lebanese population might have specific pathways of abuse. There is a need to bring together various health, legislative, and academic stakeholders for a continuous appraisal of data from substance abuse studies as evidenced by the recent, although slow, progress in the fields of legislation and treatment that follow such concerted efforts.

2006-09-01

Selected studies with specific relevance to substance abuse prevention interventions with Hispanic youth and families were examined to identify prior findings and emerging issues that may guide the design of future substance abuse prevention intervention research and its implementation with Hispanic populations. The origins of prevention research and role of risk and protective factors are examined, including culturally-specific risk and protective factors for Hispanic populations. Correlational studies, non-experimental interventions, and randomized controlled trials were examined for the period of 1974-2003. The literature search yielded 15 articles selected for this review that exhibited adequate methodological rigor. An added search for more recent studies identified three additional articles, for a total of 18 prevention intervention articles that were reviewed. Theoretical and methodological issues and recommendations are presented for future research aimed at improving the efficacy and effectiveness of future prevention intervention studies and their cultural relevance for Hispanic populations.

Niccols, Allison; Dell, Colleen Anne; Clarke, Sharon

2014-01-01

In many cultures, approximately one third of people with drug dependence are women of child-bearing age. Substance use among pregnant and parenting women is a major public health concern. Aboriginal people have some of the highest rates of substance abuse in Canada, increasing concern for detrimental health impacts, including those for women and their children. For many women, substance abuse offers a means of coping with trauma, such as childhood abuse, partner violence, and, for Aboriginal women, the intergenerational effects of colonization. In this paper, we review treatment issues for Aboriginal mothers with substance use problems and their children. We discuss gender-specific issues in substance abuse, the need for women-specific treatment, the impact of substance abuse on children and parenting, the additional risks for Aboriginal women and children, and the need for integrated programs (those that integrate pregnancy-, parenting-, and child-related services with women-specific addiction treatment). We describe New Choices as an example of an integrated program, review research on existing treatment for Aboriginal mothers with substance use issues, and describe Sheway as a promising integrated program for Aboriginal women with substance abuse issues and their young children. There are few treatment programs specifically for Aboriginal mothers with substance use issues and their children and very little research on their effectiveness. Based on our review of existing evidence, we offer recommendations for future research and practice. PMID:24976814

Psychometric Evaluation of the Substance Use Risk Profile Scale (SURPS) in an Inpatient Sample of Substance Users Using Cue-Reactivity Methodology

Schlauch, Robert C.; Crane, Cory A.; Houston, Rebecca J.; Molnar, Danielle S.; Schlienz, Nicolas J.; Lang, Alan R.

2015-01-01

The current project sought to examine the psychometric properties of a personality based measure (Substance Use Risk Profile Scale; SURPS: introversion-hopelessness, anxiety sensitivity, impulsivity, and sensation seeking) designed to differentially predict substance use preferences and patterns by matching primary personality-based motives for use to the specific effects of various psychoactive substances. Specifically, we sought to validate the SURPS in a clinical sample of substance users using cue reactivity methodology to assess current inclinations to consume a wide range of psychoactive substances. Using confirmatory factor analysis and correlational analyses, the SURPS demonstrated good psychometric properties and construct validity. Further, impulsivity and sensation-seeking were associated with use of multiple substances but could be differentiated by motives for use and susceptibility to the reinforcing effects of stimulants (i.e., impulsivity) and alcohol (i.e. sensation-seeking). In contrast, introversion-hopelessness and anxiety sensitivity demonstrated a pattern of use more focused on reducing negative affect, but were not differentiated based on specific patterns of use. Taken together, results suggests that among those receiving inpatient treatment for substance use disorders, the SURPS is a valid instrument for measuring four distinct personality dimensions that may be sensitive to motivational susceptibilities to specific patterns of alcohol and drug use.

Degradation of substance P by membrane peptidases in the rat substantia nigra: effect of selective inhibitors.

PubMed

Oblin, A; Danse, M J; Zivkovic, B

1988-01-11

The hydrolysis of substance P by membrane peptidases prepared from the rat substantia nigra was studied in the presence of selective inhibitors. Substance P degradation by synaptic and mitochondrial membranes was completely inhibited by 1,10-phenanthroline (1 mM), a non-specific metallopeptidase inhibitor. Captopril and bestatine, selective inhibitors of angiotensin converting enzyme and aminopeptidases respectively, were without effects. However, phosphoramidon (1 microM), a putative 'enkephalinase' inhibitor, selectively inhibited substance P degradation by synaptic membranes. These results suggest that a phosphoramidon-sensitive endopeptidase may be the principal enzyme responsible for substance P degradation in substantia nigra.

Attachment as an organizer of behavior: implications for substance abuse problems and willingness to seek treatment

Caspers, Kristin M; Yucuis, Rebecca; Troutman, Beth; Spinks, Ruth

2006-01-01

Background Attachment theory allows specific predictions about the role of attachment representations in organizing behavior. Insecure attachment is hypothesized to predict maladaptive emotional regulation whereas secure attachment is hypothesized to predict adaptive emotional regulation. In this paper, we test specific hypotheses about the role of attachment representations in substance abuse/dependence and treatment participation. Based on theory, we expect divergence between levels of maladaptive functioning and adaptive methods of regulating negative emotions. Methods Participants for this study consist of a sample of adoptees participating in an ongoing longitudinal adoption study (n = 208). The Semi-Structured Assessment of the Genetics of Alcohol-II [41] was used to determine lifetime substance abuse/dependence and treatment participation. Attachment representations were derived by the Adult Attachment Interview [AAI; [16

Association Between Substance Use and Gun-Related Behaviors.

Chen, Danhong; Wu, Li-Tzy

2016-01-01

Gun-related violence is a public health concern. This study synthesizes findings on associations between substance use and gun-related behaviors. Searches through PubMed, Embase, and PsycINFO located 66 studies published in English between 1992 and 2014. Most studies found a significant bivariate association between substance use and increased odds of gun-related behaviors. However, their association after adjustment was mixed, which could be attributed to a number of factors such as variations in definitions of substance use and gun activity, study design, sample demographics, and the specific covariates considered. Fewer studies identified a significant association between substance use and gun access/possession than other gun activities. The significant association between nonsubstance covariates (e.g., demographic covariates and other behavioral risk factors) and gun-related behaviors might have moderated the association between substance use and gun activities. Particularly, the strength of association between substance use and gun activities tended to reduce appreciably or to become nonsignificant after adjustment for mental disorders. Some studies indicated a positive association between the frequency of substance use and the odds of engaging in gun-related behaviors. Overall, the results suggest a need to consider substance use in research and prevention programs for gun-related violence. © The Author 2016.

Machine-learning identifies substance-specific behavioral markers for opiate and stimulant dependence

PubMed Central

Ahn, Woo-Young; Vassileva, Jasmin

2016-01-01

Background Recent animal and human studies reveal distinct cognitive and neurobiological differences between opiate and stimulant addictions; however, our understanding of the common and specific effects of these two classes of drugs remains limited due to the high rates of polysubstance-dependence among drug users. Methods The goal of the current study was to identify multivariate substance-specific markers classifying heroin dependence (HD) and amphetamine dependence (AD), by using machine-learning approaches. Participants included 39 amphetamine mono-dependent, 44 heroin mono-dependent, 58 polysubstance dependent, and 81 non-substance dependent individuals. The majority of substance dependent participants were in protracted abstinence. We used demographic, personality (trait impulsivity, trait psychopathy, aggression, sensation seeking), psychiatric (attention deficit hyperactivity disorder, conduct disorder, antisocial personality disorder, psychopathy, anxiety, depression), and neurocognitive impulsivity measures (Delay Discounting, Go/No-Go, Stop Signal, Immediate Memory, Balloon Analogue Risk, Cambridge Gambling, and Iowa Gambling tasks) as predictors in a machine-learning algorithm. Results The machine-learning approach revealed substance-specific multivariate profiles that classified HD and AD in new samples with high degree of accuracy. Out of 54 predictors, psychopathy was the only classifier common to both types of addiction. Important dissociations emerged between factors classifying HD and AD, which often showed opposite patterns among individuals with HD and AD. Conclusions These results suggest that different mechanisms may underlie HD and AD, challenging the unitary account of drug addiction. This line of work may shed light on the development of standardized and cost-efficient clinical diagnostic tests and facilitate the development of individualized prevention and intervention programs for HD and AD.

Gold diggers, video vixens, and Jezebels: stereotype images and substance use among urban African American girls.

PubMed

Wallace, Scyatta A; Townsend, Tiffany G; Glasgow, Y Marcia; Ojie, Mary Jane

2011-09-01

This study sought to examine the relationship of negative stereotype attitudes and endorsement of western standards of beauty (i.e., colorism) on the substance use behavior of low-income urban African American girls. Racial socialization was also examined as a potential moderator to identify any buffering effects of parental messages concerning race. Two hundred seventy-two African American female adolescents (mean age 13.02 years) were recruited from community venues in a Northeastern city. Adolescents completed a self-report questionnaire. Results of a series of hierarchical regression analyses indicated that girls who accepted an African American standard of beauty reported lower levels of substance use than those who endorsed colorism. Additionally, racial socialization buffered the negative relationship of colorism to substance use behavior, but only for a certain subset of girls. Tailored health interventions that consider both gender-specific and race-specific issues may improve risk behaviors, including substance use among adolescent females.

Kam, Jennifer A; Krieger, Janice L; Basinger, Erin D; Figueroa-Caballero, Andrea

2016-01-01

In this study, we examined the content of adolescents' conversations with their friends about substance use, adolescents' reactions to such conversations, and reasons why some adolescents did not engage in such conversations. Based on 25 semistructured interviews with high school students, we identified three themes: informational, persuasive, and relational messages. Informational messages included discussing how many peers use substances and clarifying rumors about a friend's substance use. Persuasive messages involved direct anti-substance-use messages (e.g., warning), direct pro-substance-use messages (e.g., legalizing marijuana), indirect anti-substance-use messages (e.g., disliking their substance-use experience), and indirect pro-substance-use messages (e.g., intentions to use substances). Relational messages included joking about substance use and establishing code words for use. Adolescents reacted to their conversations in several ways, such as shock and increased relational closeness. When adolescents did not talk about substance use with their friend, they offered several reasons, including low response efficacy and fear of ruining the friendship.

Personality, problem solving, and adolescent substance use.

PubMed

Jaffee, William B; D'Zurilla, Thomas J

2009-03-01

The major aim of this study was to examine the role of social problem solving in the relationship between personality and substance use in adolescents. Although a number of studies have identified a relationship between personality and substance use, the precise mechanism by which this occurs is not clear. We hypothesized that problem-solving skills could be one such mechanism. More specifically, we sought to determine whether problem solving mediates, moderates, or both mediates and moderates the relationship between different personality traits and substance use. Three hundred and seven adolescents were administered the Substance Use Profile Scale, the Social Problem-Solving Inventory-Revised, and the Personality Experiences Inventory to assess personality, social problem-solving ability, and substance use, respectively. Results showed that the dimension of rational problem solving (i.e., effective problem-solving skills) significantly mediated the relationship between hopelessness and lifetime alcohol and marijuana use. The theoretical and clinical implications of these results were discussed.

Effectiveness of substance abuse treatment programming for women: a review.

Ashley, Olivia Silber; Marsden, Mary Elen; Brady, Thomas M

2003-01-01

Recent research has shown that women and men differ in substance abuse etiology, disease progression, and access to treatment for substance abuse. Substance abuse treatment specifically designed for women has been proposed as one way to meet women's distinctive needs and reduce barriers to their receiving and remaining in treatment. However, relatively few substance abuse treatment programs offer specialized services for women, and effectiveness has not been fully evaluated. This article reviews the literature on the extent and effectiveness of substance abuse treatment programming for women and provides an overview of what is known about the components of successful treatment programs for women. Thirty-eight studies of the effect on treatment outcomes of substance abuse treatment programming for women were reviewed. Seven were randomized, controlled trials, and 31 were nonrandomized studies. In our review, six components of substance abuse treatment programming for women were examined: child care, prenatal care, women-only programs, supplemental services and workshops that address women-focused topics, mental health programming, and comprehensive programming. The studies found positive associations between these six components and treatment completion, length of stay, decreased use of substances, reduced mental health symptoms, improved birth outcomes, employment, self-reported health status, and HIV risk reduction. These findings suggest that to improve the future health and well-being of women and their children, there is a continued need for well-designed studies of substance abuse treatment programming for women.

2014-11-01

Young adulthood has been shown to be a time of increased substance use. Yet, not enough is known about which factors contribute to initiation and progression of substance use among young adults specifically during the transition year away from high school. A narrative review was undertaken to increase understanding of the predictors of changes in use of tobacco, alcohol, cannabis, other illicit drugs, and mental health problems among young adults during the transition period after high school. A review of academic literature examining predictors of the use of tobacco, alcohol and cannabis, and co-morbidities (e.g., co-occurring substance use and/or mental health issues) among young adults transitioning from high school to post-secondary education or the workforce. Twenty six studies were included in the review. The majority of the studies (19) examined substance use during the transition from high school to post-secondary settings. Seven studies examined substance use in post-secondary settings. The studies consistently found that substance use increases among young adults as they transition away from high school. During the transition away from high school, common predictors of substance use include substance use in high school, and peer influence. Common predictors of substance use in post-secondary education include previous substance use, peer influence, psychological factors and mental health issues. Conclusions/Importance: Further research on social contextual influences on substance use, mental health issues, gender differences and availability of substances during the transition period is needed to inform the development of new preventive interventions for this age group.

A descriptive study on emergency department doctors' and nurses' knowledge and attitudes concerning substance use and substance users.

PubMed

Kelleher, Sean; Cotter, Patrick

2009-01-01

The aim of this study was to determine emergency department doctors' and nurses' knowledge and attitudes regarding problematic substance use and substance users. Data were collected using an adapted survey questionnaire and the Substance Abuse Attitude Survey (SAAS). By means of convenience/opportunistic sampling all emergency department doctors and nurses (N=145) working in three university teaching hospitals in Ireland were asked to fill out the knowledge and attitudes questionnaire. A response rate of 46%, N=66 was achieved. Results indicate that participants' current level of knowledge about alcohol and drug misuse in general, is satisfactory. A particular knowledge deficit in relation to intervention strategies, and other substances was identified. The majority of participants have never received any specific training regarding substance use and this suggests that substance using patients are managed inadequately. The SAAS results indicate that participants exhibited near-optimal attitudes for constructive working with substance using patients. There is an urgent need for further in-service training programmes and the development of standard protocols/guidelines for the identification and management of substance using patients who present in the emergency department.

Specificity of genetic and environmental risk factors for symptoms of cannabis, cocaine, alcohol, caffeine, and nicotine dependence.

2007-11-01

Although genetic risk factors have been found to contribute to dependence on both licit and illicit psychoactive substances, we know little of how these risk factors interrelate. To clarify the structure of genetic and environmental risk factors for symptoms of dependence on cannabis, cocaine, alcohol, caffeine, and nicotine in males and females. Lifetime history by structured clinical interview. General community. Four thousand eight hundred sixty-five members of male-male and female-female pairs from the Virginia Adult Twin Study of Psychiatric and Substance Use Disorders. Main Outcome Measure Lifetime symptoms of abuse of and dependence on cannabis, cocaine, alcohol, caffeine, and nicotine. Controlling for greater symptom prevalence in males, genetic and environmental parameters could be equated across sexes. Two models explained the data well. The best-fit exploratory model contained 2 genetic factors and 1 individual environmental factor contributing to all substances. The first genetic factor loaded strongly on cocaine and cannabis dependence; the second, on alcohol and nicotine dependence. Nicotine and caffeine had high substance-specific genetic effects. A confirmatory model, which also fit well, contained 1 illicit drug genetic factor--loading only on cannabis and cocaine--and 1 licit drug genetic factor loading on alcohol, caffeine, and nicotine. However, these factors were highly intercorrelated (r = + 0.82). Large substance-specific genetic effects remained for nicotine and caffeine. The pattern of genetic and environmental risk factors for psychoactive substance dependence was similar in males and females. Genetic risk factors for dependence on common psychoactive substances cannot be explained by a single factor. Rather, 2 genetic factors-one predisposing largely to illicit drug dependence, the other primarily to licit drug dependence-are needed. Furthermore, a large proportion of the genetic influences on nicotine and particularly caffeine dependence appear to be specific to those substances.

The role of substance use motives in the associations between minority stressors and substance use problems among young men who have sex with men.

PubMed

Feinstein, Brian A; Newcomb, Michael E

2016-09-01

Young men who have sex with men (YMSM) report higher rates of substance use than their heterosexual peers and minority stress has been posited as a risk factor for substance use. The associations between specific types of minority stress and substance use have been inconsistent throughout the literature and few studies have examined mechanisms underlying these associations. Drawing on minority stress theory and the motivational model of alcohol use, we propose that one mechanism underlying these associations may be people's motivations for using substances, including using substances to cope with negative emotions and to enhance pleasure. The goals of the current study were: (1) to examine the associations among minority stressors, substance use motives, and substance use problems; and (2) to examine substance use motives as mediators of the associations between minority stressors and substance use problems. Baseline self-report data were used from a cohort of 370 YMSM enrolled in a larger study of substance use and sexual behavior. Results indicated that using marijuana to cope mediated the association between victimization and marijuana use problems. Using other drugs to cope mediated the associations between victimization and drug use problems and between internalized stigma and drug use problems. Drinking to cope and to enhance pleasure mediated the association between internalized stigma and alcohol use problems. In sum, substance use motives, especially using substances to cope, act as mechanisms through which certain types of minority stress influence substance use problems among YMSM.

Substance-related deaths account for a great number of suicides. To investigate levels and characteristics of suicide verdicts, as opposed to accidental deaths, in substance misusers. Psychological autopsy study of cases from the UK National Programme on Substance Abuse Deaths (np-SAD) during the period 2001-2007. Between January 2001 and December 2007, 2108 suicides were reported to the np-SAD. Typical suicide victims were White and older than 50 (respectively 95% and 41% of cases). Medications, especially antidepressants (44%), were prescribed to 87% of victims. Significantly fewer suicide victims than controls presented positive blood toxicological results for illicit drugs (namely: cocaine, heroin, amphetamines, ecstasy-type drugs, cannabis, and GHB/GBL) and alcohol. Suicide prevention programmes should devote specific attention to deaths among substance misusers who are at high risk of fatal intentional self-harm. Specific characteristics distinguish those at risk; caregivers should be better educated as to what these factors are. Limitations of the current study included lack of provision of comprehensive information relating to the victims' psychosocial variables. Furthermore, no differentiation between different classes of antidepressants in terms of involvement in suicide was here provided. Copyright © 2011 Elsevier Inc. All rights reserved.

Adolescents with substance use disorders are more likely to have a current psychiatric disorder. However, when compared with the adult literature, there is relatively limited information regarding the specific co-occurrence of certain mental health diagnoses and substance use disorders in adolescents. The objectives of this study were to build on the previous literature regarding mental health diagnoses and different types of substance use disorders in adolescents, as well as explore the differences, if any, between groupings of mental health diagnosis and type of substance used. Data were extracted from the clinical records of 483 individuals aged 11-24 years referred for an evaluation at the Adolescent Substance Abuse Program at Boston Children's Hospital. According to DSM-IV-Text Revision criteria, individuals received diagnoses of substance abuse or dependence and any additional psychiatric disorders. Problematic use was included within the sample for greater power analysis. A multivariable logistic regression model estimated the association between psychiatric diagnosis and substance use while adjusting for covariates including age and gender. Multiple significant associations were found, including having any anxiety-related diagnosis and opioid use (odds ratio [OR] = 2.23, p < .001), generalized anxiety disorder and opioids (OR = 3.42, p = .008), cocaine and post-traumatic stress disorder (OR = 3.61, p = .01), and marijuana and externalizing behavior disorders (OR = 2.10, p = .024). Our study found multiple significant associations between specific substances and certain co-occurring psychiatric disorders. The use of office screening systems to efficiently identify these youths should be a part of routine medical and psychiatric care. Copyright © 2017 Society for Adolescent Health and Medicine.

Comorbid substance use disorder in schizophrenia: a selective overview of neurobiological and cognitive underpinnings.

PubMed

Thoma, Patrizia; Daum, Irene

2013-09-01

Although individuals with schizophrenia show a lifetime prevalence of 50% for suffering from a comorbid substance use disorder, substance abuse usually represents an exclusion criterion for studies on schizophrenia. This implies that surprisingly little is known about a large group of patients who are particularly difficult to treat. The aim of the present work is to provide a brief and non-exhaustive overview of the current knowledgebase about neurobiological and cognitive underpinnings for dual diagnosis schizophrenia patients. Studies published within the last 20 years were considered using computerized search engines. The focus was on nicotine, caffeine, alcohol, cannabis and cocaine being among the most common substances of abuse. All drugs of abuse target dopaminergic, glutamatergic and GABAergic transmission which are also involved in the pathophysiology of schizophrenia. Current literature suggests that neurocognitive function might beless disrupted in substance-abusing compared to non-abusing schizophrenia patients, but in particular the neuroimaging database on this topic is sparse. Detrimental effects on brain structure and function were shown for patients for whom alcohol is the main substance of abuse. It is as yet unclear whether this finding might be an artifact of age differences of patient subgroups with different substance abuse patterns. More research is warranted on the specific neurocognitive underpinnings of schizophrenia patients abusing distinct psychoactive substances. Treatment programs might either benefit from preserved cognitive function as a resource or specifically target cognitive impairment in different subgroups of addicted schizophrenia patients. © 2013 The Authors.

Parental Substance Use Impairment, Parenting and Substance Use Disorder Risk

Arria, Amelia M.; Mericle, Amy A.; Meyers, Kathleen; Winters, Ken C.

2011-01-01

Using data from a nationally representative sample, this study investigated substance use disorder (SUD) among respondents ages 15-54 as a function of their parents’ substance-related impairment and parents’ treatment history. Additionally, associations among maternal and paternal substance-related impairment, specific parenting behaviors, and the risk for SUD in the proband were examined. As expected, parental substance-related impairment was associated with SUD. Paternal treatment history was associated with a decreased risk for SUD in the proband, but did not appear to be associated with positive parenting practices. Results of post-hoc analyses suggested that parenting behaviors might operate differently to influence SUD risk in children where parents are affected by substance use problems compared to non-affected families. Future research is warranted to better understand the complex relationships among parental substance use, treatment, parenting behaviors, and SUD risk in offspring. Opportunities might exist within treatment settings to improve parenting skills. PMID:22112506

Clinical and population-based samples show high comorbidity between Substance Use Disorders (SUDs) and Axis II Personality Disorders (PDs). However, Axis II disorders are frequently comorbid with each other, and existing research has generally failed to distinguish the extent to which SUD/PD comorbidity is general or specific with respect to both specific types of PDs and specific types of SUDs. We sought to determine whether ostensibly specific comorbid substance dependence-Axis II diagnoses (e.g., alcohol use dependence and borderline personality disorder) are reflective of more pervasive or general personality pathology or whether the comorbidity is specific to individual PDs. Face-to-face interview data from Wave 1 and Wave 2 of the National Epidemiologic Survey on Alcohol and Related Conditions were analyzed. Participants included 34,653 adults living in households in the United States. We used hierarchical factor models to statistically partition general and specific personality disorder dimensions while simultaneously testing for specific PD-substance dependence relations. Results indicated that substance dependence-Axis II comorbidity is characterized by general (pervasive) pathology and by Cluster B PD pathology over and above the relationship to the general PD factor. Further, these relations between PD factors and substance dependence diagnoses appeared to largely account for the comorbidity among substance dependence diagnoses in the younger but not older participants. Our findings suggest that a failure to consider the general PD factor, which we interpret as reflecting interpersonal dysfunction, can lead to potential mischaracterizations of the nature of certain PD and SUD comorbidities.

Berge, J; Sundell, K; Öjehagen, A; Håkansson, A

2016-01-01

Objective Adolescent substance use is an area of concern because early substance use is associated with a higher risk of adverse outcomes. Parenting style, defined as the general style of parenting, as well as substance-specific parenting practices may influence children's substance use behaviour. The present study aims to probe the impact of parenting style on adolescent substance use. Method A cohort of 1268 adolescents (48% girls), aged 12–13 years at baseline, from 21 junior high schools was assessed in the first semester of junior high school, and then again in the last semester of the 9th grade, 32 months later. Parenting style, operationalised as a fourfold classification of parenting styles, including established risk factors for adolescent substance use, were measured at baseline. Results Neglectful parenting style was associated with worse substance use outcomes across all substances. After adjusting for other proximal risk factors in multivariate analyses, parenting style was found to be unrelated to substance use outcomes with one exception: authoritative parenting style was associated with less frequent drinking. Association with deviant peers, delinquent behaviour, provision of alcohol by parents, and previous use of other substances were associated with substance use outcomes at follow-up. Conclusions The results of the present study indicate that parenting style may be less important for adolescent substance use outcomes than what has previously been assumed, and that association with deviant peers and delinquent behaviour may be more important for adolescent substance use outcomes than general parenting style.

To report on the development of a questionnaire to screen for hazardous substance use in pregnant women and to compare the performance of the questionnaire with other drug and alcohol measures. Pregnant women were administered a modified TWEAK (Tolerance, Worried, Eye-openers, Amnesia, K[C] Cut Down) questionnaire, the 4Ps Plus questionnaire, items from the Addiction Severity Index, and two questions about domestic violence (N=2,684). The sample was divided into "training" (n=1,610) and "validation" (n=1,074) subsamples. We applied recursive partitioning class analysis to the responses from individuals in the training subsample that resulted in a three-item Substance Use Risk Profile-Pregnancy scale. We examined sensitivity, specificity, and the fit of logistic regression models in the validation subsample to compare the performance of the Substance Use Risk Profile-Pregnancy scale with the modified TWEAK and various scoring algorithms of the 4Ps. The Substance Use Risk Profile-Pregnancy scale is comprised of three informative questions that can be scored for high- or low-risk populations. The Substance Use Risk Profile-Pregnancy scale algorithm for low-risk populations was mostly highly predictive of substance use in the validation subsample (Akaike's Information Criterion=579.75, Nagelkerke R=0.27) with high sensitivity (91%) and adequate specificity (67%). The high-risk algorithm had lower sensitivity (57%) but higher specificity (88%). The Substance Use Risk Profile-Pregnancy scale is simple and flexible with good sensitivity and specificity. The Substance Use Risk Profile-Pregnancy scale can potentially detect a range of substances that may be abused. Clinicians need to further assess women with a positive screen to identify those who require treatment for alcohol or illicit substance use in pregnancy. III.

The Emerging Role of Meditation in Addressing Psychiatric Illness, with a Focus on Substance Use Disorders

Dakwar, Elias; Levin, Frances R.

2011-01-01

Over the past 30 years the practice of meditation has become increasingly popular in clinical settings. In addition to evidence-based medical uses, meditation may have psychiatric benefits. In this review, the literature on the role of meditation in addressing psychiatric issues, and specifically substance use disorders, is discussed. Each of the three meditation modalities that have been most widely studied—transcendental meditation, Buddhist meditation, and mindfulness-based meditation—is critically examined in terms of its background, techniques, mechanisms of action, and evidence-based clinical applications, with special attention given to its emerging role in the treatment of substance use disorders. The unique methodological difficulties that beset the study of meditation are also considered. A brief discussion then integrates the research that has been completed thus far, elucidates the specific ways that meditation may be helpful for substance use disorders, and suggests new avenues for research.

2017-01-01

This current study identifies distinct parent prevention communication profiles and examines whether youth with different parental communication profiles have varying substance use trajectories over time. Eleven schools in two rural school districts in the Midwestern United States were selected, and 784 students were surveyed at three time points from the beginning of 7th grade to the end of 8th grade. A series of latent profile analyses were performed to identify discrete profiles/subgroups of substance-specific prevention communication (SSPC). The results revealed a 4-profile model of SSPC: Active-Open, Passive-Open, Active-Silent, and Passive-Silent. A growth curve model revealed different rates of lifetime substance use depending on the youth’s SSPC profile. These findings have implications for parenting interventions and tailoring messages for parents to fit specific SSPC profiles. PMID:29056872

Development of risk perception and substance use of tobacco, alcohol and cannabis among adolescents and emerging adults: evidence of directional influences.

PubMed

Grevenstein, Dennis; Nagy, Ede; Kroeninger-Jungaberle, Henrik

2015-02-01

While several studies have investigated the relationship between risk perception and substance use, surprisingly little is known about mutual influences between both variables over time. The present study aimed to explore two different hypotheses separately for tobacco, alcohol and cannabis: influences from risk perception on behavior (motivational hypothesis) and influences from behavior on risk perception (risk reappraisal hypothesis). A prospective and longitudinal cross-lagged panel design was used with substance use and risk perception measured five times over the course of 10 years. Participants were 318 German youths aged 14-15 at the beginning of the study. Risk perception and substance use frequency were measured using self-reports. Structural equation modeling indicated significant influences of risk perception on substance use behavior for all substances, which supports the motivational hypothesis. Changes in risk perception predict changes in future substance use of tobacco, alcohol and cannabis. Specifically for cannabis, influences of substance use on risk perception can also be shown, thus, supporting the risk reappraisal hypothesis. While there is support for the rationale behind adequate risk perception as a goal of preventive interventions, the possibility of risk reappraisal should not be neglected, especially regarding illicit substances.

To identify the substances used by people who die from suicide by overdose in Toronto and to determine the correlates of specific categories of substances used. Coroner's records for all cases of suicide by overdose in Toronto, Ontario, during a 10-year period (1998 to 2007) were examined. Data collected included demographic data, all substances detected, and those determined by the coroner to have caused death. Logistic regression analyses were used to examine demographic and clinical factors associated with suicide by different drug types. There were 397 documented suicides by overdose (mean age 49.1 years, 50% female). Most substances detected were psychotropic prescription medications (n = 245), followed by other prescription medications (n = 143) and over-the-counter (OTC) medications (n = 83). More than one-half of all suicides by overdose were determined to have only one specific substance as the cause of death (n = 206). In suicides where only one class of substance was present in lethal amounts, OTC medication (n = 48), opioid analgesics (n = 44), and tricyclic antidepressants (n = 44) were most common. Suicides by overdose involved the use of different classes of substances, including psychotropic prescription medication, other prescription medications, as well as OTC medications. Physicians and pharmacists should be aware of commonly used prescription and OTC medications in overdose and exercise increased vigilance in prescribing or dispensing them to at-risk patients.

Substance Abuse Treatment in Persons with HIV/AIDS: Challenges in Managing Triple Diagnosis

PubMed Central

Durvasula, Ramani; Miller, Theodore R.

2014-01-01

This paper provides a review of the current literature addressing substance abuse treatment in persons living with HIV/AIDS. Clinical management of HIV must account for the “triple diagnosis” of HIV, psychiatric diagnosis, and substance use disorders and requires integrated treatment services that focus beyond just mitigation of substance use and psychiatric and medical symptoms but also address other health behaviors. Because clinical management of HIV/AIDS has shifted significantly with the advent of highly active antiretroviral therapies (HAART) in the mid 1990's, a literature review focusing on literature published since 2000, and using relevant key words was conducted using a wide range of literature search databases. This literature review was complemented by studies to expand on specific treatment modalities for which there was a dearth of literature addressing HIV infected cohorts and to provide discussion of issues around substance abuse treatment as an HIV prevention tool. Existing models of substance abuse treatment including cognitive behavioral therapy and motivational interviewing have proven to be useful for enhancing adherence and reducing substance use in outpatient populations, while methadone maintenance and directly observed treatment have been useful with specific subgroups of users. Contextualization of services heightens the likelihood of successful outcomes and relapse prevention. PMID:24274175

Research suggests that individual and environmental resilience protective factors may be associated with adolescent substance use; however, the associations between a broad range of such factors and use of various types of substances have not been examined. The study aimed to determine the association between a comprehensive range of adolescent individual and environmental resilience protective factors and measures of tobacco, alcohol and illicit substance use. Cross-sectional study. 32 Australian secondary schools. Grade 7-10 students (aged 11-17 years). Data regarding 14 student individual and environmental resilience protective factors and seven substance use measures (tobacco, alcohol, marijuana, other illicit drug use) were obtained via an online self-report survey. Adjusted multivariate logistic regression analyses examined the association between all student resilience protective factors and seven substance use measures. Inverse univariate associations were found for 94 of 98 relationships examined (n=10 092). Multivariate analyses found: consistent inverse associations between 2 of 14 protective factors and all substance use measures ('goals and aspirations', 'prosocial peers'); inverse associations between 4 protective factors with multiple substance use measures ('home support' (5 of 7), 'school support' (3 of 7), 'self-awareness' (2 of 7), 'community meaningful participation' (2 of 7)); positive associations between 2 resilience protective factors with multiple measures of substance use ('community support' (3 of 7), 'peer caring relationships' (5 of 7)) and 6 protective factors not to be associated with any substance use measure. Despite individual relationships between the majority of resilience protective factors and substance use types, the protective benefit of such factors for adolescent substance use was limited to only a small number of such factors when considered collectively. Such results suggest that interventions seeking to reduce adolescent substance use may need to target specific protective factors to address specific types of substance use.

This study introduces an observational measure of fidelity in evidence-based practices for adolescent substance abuse treatment. The Therapist Behavior Rating Scale-Competence (TBRS-C) measures adherence and competence in individual cognitive-behavioral therapy and multidimensional family therapy for adolescent substance abuse. The TBRS-C assesses fidelity to the core therapeutic goals of each approach and also contains global ratings of therapist competence. Study participants were 136 clinically referred adolescents and their families observed in 437 treatment sessions. The TBRS-C demonstrated strong interrater reliability for goal-specific ratings of treatment adherence, and modest reliability for goal-specific and global ratings of therapist competence, evidence of construct validity, and discriminant validity with an observational measure of therapeutic alliance. The utility of the TBRS-C for evaluating treatment fidelity in field settings is discussed.

A Review on Attachment and Adolescent Substance Abuse: Empirical Evidence and Implications for Prevention and Treatment.

PubMed

Schindler, Andreas; Bröning, Sonja

2015-01-01

This paper reviews research on the relation of attachment and substance use disorders (SUD) in adolescence. Based on a theoretical introduction, we review evidence for a possible general link between SUD and insecure attachment, for links between specific forms of SUD and specific patterns of attachment, and for studies on family patterns of attachment in adolescence. Using medical and psychological databases, we identified 10 studies on adolescent SUD and another 13 studies on adult SUD. Empirical evidence strongly supports the assumption of insecure attachment in SUD samples. With regard to specific patterns of attachment, results mainly point towards fearful and dismissing-avoidance, whereas single studies report preoccupied and unresolved patterns. Results indicate different patterns of attachment in different groups of substance abusers, that is, fearful-avoidant attachment in heroin addicts and more heterogeneous results in abusers of other substances. Explorative data suggest different types of insecure family attachment patterns, which might imply different functions of substance abuse and lead to different treatment recommendations. Methodological problems such as poor assessment of SUD and the use of different measures of attachment limit comparability. Although a lot of research is still needed to address the unknowns in the relation between attachment and SUD, there is strong evidence for a general link between SUD and insecure attachment. Data on connections between different patterns of attachment and different pathways towards SUD are less conclusive but mainly point to disorganized and externalizing pathways. Evidence suggests that fostering attachment security might improve the outcome of state-of-the-art approaches in both early interventional treatment and prevention. Implications for individual and family approaches are outlined.

The relationship between antisocial and borderline features and aggression in young adult men in treatment for substance use disorders

There is a large literature documenting that adult men in treatment for substance use disorders perpetrate more aggression than men without substance use disorders. Unfortunately, there is minimal research on aggression among young adult men (i.e., 18–25 years of age) in treatment for substance use. Moreover, although aggression is more likely to occur when individuals are acutely intoxicated by alcohol or drugs, research also suggests that antisocial (ASPD) and borderline (BPD) personality features increase the chances an individual will use aggression. The current study therefore examined the associations between ASPD and BPD features, including specific features that are reflective of impulsivity, and aggression in young adult men in treatment for substance use disorders (N = 79). Controlling for age, education, alcohol and drug use, ASPD features were positively associated with various indicators of aggression (e.g., physical, verbal, attitudinal), whereas BPD features were only associated with physical aggression. However, ASPD and BPD features that were specific to impulsivity were robustly related to indicators of aggression. Findings suggest that substance use treatment should attempt to target ASPD and BPD features in young adult men, which may help reduce aggression after treatment. PMID:26941068

Role transitions and substance use among Hispanic emerging adults: A longitudinal study using coarsened exact matching.

Emerging adulthood (ages 18 to 25) is characterized by changes in relationships, education, work, and viewpoints on life. The prevalence of substance use also peaks during this period. Among emerging adults, Hispanics have a unique substance use profile, and have been described as a priority population for substance use prevention. Cross-sectional studies among Hispanics have shown that specific role transitions (e.g., starting or ending romantic relationships) were associated with substance use. Negative affect from uncertainty/stress that accompanies role transitions in emerging adulthood may lead to substance use as a maladaptive coping mechanism. Longitudinal studies are needed to gain a more complete understanding of these associations. Participants completed surveys for Project RED, a longitudinal study of substance use among Hispanics in Southern California. This study used Coarsened Exact Matching to overcome the methodological limitations of previous studies. Participants were matched on pretreatment variables including age, gender, substance use behavior in high school, and depressive symptoms. Past-month cigarette use, binge drinking, marijuana use, and hard drug use were the outcomes of interest. After matching, each outcome was regressed on each individual role transition in year one of emerging adulthood with this process repeated in year two of emerging adulthood. Role transitions in romance and work were positively associated with multiple categories of substance use. Prevention programs should teach emerging adults ways to cope with the stress from role transitions. Individual role transitions may be used to screen for subgroups of emerging adults at high risk for substance use. Copyright © 2015 Elsevier Ltd. All rights reserved.

Objective: Substance use is associated with poor mental health, but little is known regarding how use of multiple substances is associated with mental health, particularly longitudinally, in community studies. This article examines this issue in a large (N = 710), natural-history study of rural stimulant (cocaine and/or methamphetamine) users in three states. Method: Respondent-driven sampling recruited recent (past-30-day) stimulant users in three counties each in Arkansas, Kentucky, and Ohio. Participants were interviewed every 6 months for 3 years. Mental health was measured by the Brief Symptom Inventory, and prior 6 months' substance use was measured for 17 possible substances. Data analysis used generalized estimating equations for longitudinal data with the Global Severity Index of the Brief Symptom Inventory as the dependent variable at each interview and substance use as predictor variables measured by number of substances used in the past 6 months and, separately, the 17 individual substances, adjusting for use of substance-use treatment, demographics, and recruitment site. Results: On average, both Global Severity Index score and use of many substances declined over the course of study. Global Severity Index score was significantly associated with (a) greater number of substances used in the past 6 months (p < .0001) and (b) use of crack cocaine, methamphetamine, and nonprescription use of prescription painkillers and tranquilizers. Conclusions: Multiple and specific substances appear to incrementally increase psychological distress. Users of cocaine and methamphetamine are present in rural areas; these associations with poor psychological health raise concerns regarding availability of local treatment services for individuals with mental-health problems, as well as substance abuse.

Machine-learning identifies substance-specific behavioral markers for opiate and stimulant dependence.

PubMed

Ahn, Woo-Young; Vassileva, Jasmin

2016-04-01

Recent animal and human studies reveal distinct cognitive and neurobiological differences between opiate and stimulant addictions; however, our understanding of the common and specific effects of these two classes of drugs remains limited due to the high rates of polysubstance-dependence among drug users. The goal of the current study was to identify multivariate substance-specific markers classifying heroin dependence (HD) and amphetamine dependence (AD), by using machine-learning approaches. Participants included 39 amphetamine mono-dependent, 44 heroin mono-dependent, 58 polysubstance dependent, and 81 non-substance dependent individuals. The majority of substance dependent participants were in protracted abstinence. We used demographic, personality (trait impulsivity, trait psychopathy, aggression, sensation seeking), psychiatric (attention deficit hyperactivity disorder, conduct disorder, antisocial personality disorder, psychopathy, anxiety, depression), and neurocognitive impulsivity measures (Delay Discounting, Go/No-Go, Stop Signal, Immediate Memory, Balloon Analogue Risk, Cambridge Gambling, and Iowa Gambling tasks) as predictors in a machine-learning algorithm. The machine-learning approach revealed substance-specific multivariate profiles that classified HD and AD in new samples with high degree of accuracy. Out of 54 predictors, psychopathy was the only classifier common to both types of addiction. Important dissociations emerged between factors classifying HD and AD, which often showed opposite patterns among individuals with HD and AD. These results suggest that different mechanisms may underlie HD and AD, challenging the unitary account of drug addiction. This line of work may shed light on the development of standardized and cost-efficient clinical diagnostic tests and facilitate the development of individualized prevention and intervention programs for HD and AD.

Maternal Neural Responses to Infant Cries and Faces: Relationships with Substance Use

Substance abuse in pregnant and recently post-partum women is a major public health concern because of effects on the infant and on the ability of the adult to care for the infant. In addition to the negative health effects of teratogenic substances on fetal development, substance use can contribute to difficulties associated with the social and behavioral aspects of parenting. Neural circuits associated with parenting behavior overlap with circuits involved in addiction (e.g., frontal, striatal, and limbic systems) and thus may be co-opted for the craving/reward cycle associated with substance use and abuse and be less available for parenting. The current study investigates the degree to which neural circuits associated with parenting are disrupted in mothers who are substance-using. Specifically, we used functional magnetic resonance imaging to examine the neural response to emotional infant cues (faces and cries) in substance-using compared to non-using mothers. In response to both faces (of varying emotional valence) and cries (of varying distress levels), substance-using mothers evidenced reduced neural activation in regions that have been previously implicated in reward and motivation as well as regions involved in cognitive control. Specifically, in response to faces, substance users showed reduced activation in prefrontal regions, including the dorsolateral and ventromedial prefrontal cortices, as well as visual processing (occipital lobes) and limbic regions (parahippocampus and amygdala). Similarly, in response to infant cries, substance-using mothers showed reduced activation relative to non-using mothers in prefrontal regions, auditory sensory processing regions, insula and limbic regions (parahippocampus and amygdala). These findings suggest that infant stimuli may be less salient for substance-using mothers, and such reduced saliency may impair developing infant-caregiver attachment and the ability of mothers to respond appropriately to their infants.

Chemical disguise of myrmecophilous cockroaches and its implications for understanding nestmate recognition mechanisms in leaf-cutting ants.

Cockroaches of the genus Attaphila regularly occur in leaf-cutting ant colonies. The ants farm a fungus that the cockroaches also appear to feed on. Cockroaches disperse between colonies horizontally (via foraging trails) and vertically (attached to queens on their mating flights). We analysed the chemical strategies used by the cockroaches to integrate into colonies of Atta colombica and Acromyrmex octospinosus. Analysing cockroaches from nests of two host species further allowed us to test the hypothesis that nestmate recognition is based on an asymmetric mechanism. Specifically, we test the U-present nestmate recognition model, which assumes that detection of undesirable cues (non-nestmate specific substances) leads to strong rejection of the cue-bearers, while absence of desirable cues (nestmate-specific substances) does not necessarily trigger aggression. We found that nests of Atta and Acromyrmex contained cockroaches of two different and not yet described Attaphila species. The cockroaches share the cuticular chemical substances of their specific host species and copy their host nest's colony-specific cuticular profile. Indeed, the cockroaches are accepted by nestmate but attacked by non-nestmate ant workers. Cockroaches from Acromyrmex colonies bear a lower concentration of cuticular substances and are less likely to be attacked by non-nestmate ants than cockroaches from Atta colonies. Nest-specific recognition of Attaphila cockroaches by host workers in combination with nest-specific cuticular chemical profiles suggest that the cockroaches mimic their host's recognition labels, either by synthesizing nest-specific substances or by substance transfer from ants. Our finding that the cockroach species with lower concentration of cuticular substances receives less aggression by both host species fully supports the U-present nestmate recognition model. Leaf-cutting ant nestmate recognition is thus asymmetric, responding more strongly to differences than to similarities.

OBJECTIVE To report on the development of a questionnaire to screen for hazardous substance use in pregnant women and to compare the performance of the questionnaire with other drug and alcohol measures. METHODS Pregnant women were administered a modified TWEAK (Tolerance, Worried, Eye-openers, Amnesia, K[C] Cut Down) questionnaire, the 4Ps Plus questionnaire, items from the Addiction Severity Index, and two questions about domestic violence (N=2,684). The sample was divided into “training” (n=1,610) and “validation” (n=1,074) subsamples. We applied recursive partitioning class analysis to the responses from individuals in the training subsample that resulted in a three-item Substance Use Risk Profile-Pregnancy scale. We examined sensitivity, specificity, and the fit of logistic regression models in the validation subsample to compare the performance of the Substance Use Risk Profile-Pregnancy scale with the modified TWEAK and various scoring algorithms of the 4Ps. RESULTS The Substance Use Risk Profile-Pregnancy scale is comprised of three informative questions that can be scored for high- or low-risk populations. The Substance Use Risk Profile-Pregnancy scale algorithm for low-risk populations was mostly highly predictive of substance use in the validation subsample (Akaike’s Information Criterion=579.75, Nagelkerke R2=0.27) with high sensitivity (91%) and adequate specificity (67%). The high-risk algorithm had lower sensitivity (57%) but higher specificity (88%). CONCLUSION The Substance Use Risk Profile-Pregnancy scale is simple and flexible with good sensitivity and specificity. The Substance Use Risk Profile-Pregnancy scale can potentially detect a range of substances that may be abused. Clinicians need to further assess women with a positive screen to identify those who require treatment for alcohol or illicit substance use in pregnancy. PMID:20859145

**1**5N-NMR INVESTIGATION OF HYDROXYLAMINE DERIVATIZED HUMIC SUBSTANCES.

Humic substances are the most abundant naturally occurring refactory organic compounds in soils and water. They have a broad range of physical, chemical and physiological properties. In soils, humic substances contribute to the cation exchange capacity, help maintain the physical structure, and play a role in plant growth and nutrition. In aquatic systems, humic substances serve to regulate the levels of inorganic constituents, yield trihalomethanes upon chlorination, and transport or concentrate organic and inorganic pollutants. The oxygen containing functional groups of humic and fulvic acids are believed to play a key role in the chemical properties of humic substances. This study was undertaken to gain additional information on the specific types of oxygen functionalities in humic substances. Since the analysis of hydroxyl moieties had been earlier established, we focused our attention on the analysis of ketone and aldehyde functional groups in humic substances.

Investigating Social Support and Network Relationships in Substance Use Disorder Recovery.

Stevens, Ed; Jason, Leonard A; Ram, Daphna; Light, John

2015-01-01

Social support and characteristics of one's social network have been shown to be beneficial for abstinence and substance use disorder recovery. The current study explores how specific sources of social support relate to general feelings of social support and abstinence-specific self-efficacy. Data were collected from 31 of 33 individuals residing in 5 recovery houses. Participants were asked to complete social support and social network measures, along with measures assessing abstinence from substance use, abstinence self-efficacy, and involvement in 12-step groups. A significant positive relationship was found between general social support and abstinence-specific self-efficacy. General social support was also significantly associated with the specific social support measures of sense of community and Alcoholics Anonymous (AA) affiliation. Social network size predicted abstinence-related factors such as AA affiliation and perceived stress. These results provide insight regarding individual feelings of social support and abstinence-specific self-efficacy by showing that one's social network-level characteristics are related to one's perceptions of social support. We also found preliminary evidence that individual Oxford Houses influence one's feelings of social support.

Parental smoking and adolescent problem behavior: an adoption study of general and specific effects.

It is essential to understand the effect of parental smoking on offspring tobacco use. In biologically related families, parents who smoke may transmit a nonspecific genetic risk for offspring disinhibited behavior, including tobacco use. Studying adoptive families allows one to control for genetic confounding when examining the environmental effect of exposure to parental smoking. The purpose of this study was to examine the genetic and environmental contributions to the risk represented by exposure to parental smoking and to assess the specificity of that risk. Adolescents adopted in infancy were systematically ascertained from records of three private Minnesota adoption agencies; nonadopted adolescents were ascertained from Minnesota birth records. Adolescents and their rearing parents participated in all assessments in person. The main outcome measures were self-reports of behavioral deviance, substance use, and personality, as well as DSM-IV clinical assessments of childhood disruptive disorders. The data from adoptive families suggest that exposure to parental smoking represents an environmental risk for substance use in adolescent offspring. In biologically related families, the effect of exposure to parental smoking is larger and more diverse, including substance use, disruptive behavior disorders, delinquency, deviant peer affiliations, aggressive attitudes, and preference for risk taking. This study provides evidence for an environmentally mediated pathway by which parental smoking increases risk specifically for substance use in adolescent offspring. The data are also consistent with a genetically mediated pathway by which nonadoptive parents who smoke may also transmit a nonspecific genetic risk to their offspring for disinhibited behavior.

Role of parenting styles in adolescent substance use: results from a Swedish longitudinal cohort study.

PubMed

Berge, J; Sundell, K; Öjehagen, A; Håkansson, A

2016-01-14

Adolescent substance use is an area of concern because early substance use is associated with a higher risk of adverse outcomes. Parenting style, defined as the general style of parenting, as well as substance-specific parenting practices may influence children's substance use behaviour. The present study aims to probe the impact of parenting style on adolescent substance use. A cohort of 1268 adolescents (48% girls), aged 12-13 years at baseline, from 21 junior high schools was assessed in the first semester of junior high school, and then again in the last semester of the 9th grade, 32 months later. Parenting style, operationalised as a fourfold classification of parenting styles, including established risk factors for adolescent substance use, were measured at baseline. Neglectful parenting style was associated with worse substance use outcomes across all substances. After adjusting for other proximal risk factors in multivariate analyses, parenting style was found to be unrelated to substance use outcomes with one exception: authoritative parenting style was associated with less frequent drinking. Association with deviant peers, delinquent behaviour, provision of alcohol by parents, and previous use of other substances were associated with substance use outcomes at follow-up. The results of the present study indicate that parenting style may be less important for adolescent substance use outcomes than what has previously been assumed, and that association with deviant peers and delinquent behaviour may be more important for adolescent substance use outcomes than general parenting style.

Background Substance use is associated with HIV sexual risk behaviors, yet few studies have examined substance use patterns longitudinally. We evaluated the types and frequency of substances used over a six-month period among U.S. women at risk for HIV acquisition. Methods Women reporting unprotected sex with a man in the previous six months and at least one other personal or partner HIV risk characteristic enrolled in a multisite cohort study and completed interviews about substance use at study visits. Prevalence and frequency of substance use at the baseline and six-month visits were compared and correlates of decreased substance use at the six-month visit were assessed. Results Of 2,099 women enrolled, 1,882 had substance use data at baseline and six-months. Of these, 76.1% reported using at least one drug or binge drinking in the previous six months; 37.5% were frequent and 38.6% non-frequent substance users. Binge drinking was most frequently reported (63.3%), followed by cocaine (25.0%) and opioids (16.5%). Fifty-five percent of opiate users and 30% of cocaine users reported daily/almost daily use. At the six-month visit, 40.5% reported a decrease in frequency of use. Adjusting for income and type of drug used, poly-substance users were less likely to decrease frequency of use compared to those who only used one substance. Conclusion A substantial decrease in frequency of substance use over time was observed in this cohort. Poly-substance users were less likely to reduce frequency of use over time, suggesting that specific substance use interventions targeting these users are warranted. PMID:24698079

2011-01-01

The aim of this study was to compare people with substance use disorder with healthy controls in terms of childhood abuse, proclivity towards substance abuse, coping skills and self-esteem as well as the correlation between experiences of abuse in childhood and these variables. The study group included 41 subjects diagnosed with substance use disorder, who had been sentenced under the respective laws as a result of crimes relating to substance use and possession, and the control group. A sociodemographic Data Form, SCID-I, Childhood Trauma Questionnaire, COPE, Substance Abuse Proclivity Scale and Rosenberg Self-Esteem Scale were applied to all participants. Childhood trauma history was observed to be more common in the study group than in the control group. When the childhood trauma questionnaire was evaluated, the scores for physical abuse were found to be significantly higher in the study group. COPE subscale scores for mental disengagement, focusing on problems and expressing emotions, active coping, coping through religion and emotional social support usage were significantly lower in the study group. The study group's results on the Substance Abuse Proclivity Scale were found to be higher than those of the control group. On the Rosenberg Self Respect Scale, the study group's scores were higher while the control group was more likely to have high self respect. People with substance use disorder are more likely to have a childhood history of physical abuse, higher proclivity towards substance abuse and lower self esteem. The level of abuse increases the level of emotion-based coping while decreasing levels of problem-based coping. There is support for the view that that traumatic childhood experiences are one of the psychosocial risk factors related to, although not specific to substance use.

The present study examined costs of two residential substance abuse treatment programs designed for urban American Indians and Alaska Natives (AI/ANs). Costs for one agency were well within national norms, while costs at the other program were less than expected from nationwide data. Economies of scale accounted for much of the difference between observed and expected costs. Culturally specific residential substance abuse treatment services can be provided to urban AI/ANs within budgets typically found at mainstream programs.

Public perceptions of behavioral and substance addictions.

PubMed

Lang, Brent; Rosenberg, Harold

2017-02-01

Most of the research on public perceptions of people with addictive disorders has focused on alcohol and illicit drugs, rather than addiction to behavioral activities. To expand the range of addictive behaviors and types of perceptions studied, we designed the present study to assess the lay public's definitions of and willingness to affiliate with people described as addicted to 1 of 2 specific behaviors (i.e., pornography or gambling) or 1 of 3 specific substances (i.e., alcohol, marijuana, or heroin). A nationwide convenience sample (N = 612) of American adults completed online questionnaires during the summer of 2015. Participants rated heroin as more addictive than the other drugs and behaviors and, despite differences among the conditions, were generally unwilling to affiliate with an individual addicted to any of the 2 behaviors or 3 substances. When asked to rate different potential indications of addiction, participants endorsed behavioral signs of impaired control and physiological and psychological dependence as more indicative of all 5 types of addiction than desire to use the substance or engage in the addictive behavior. Despite recent efforts to increase public knowledge about addictive disorders, members of the public continue to endorse some attitudes indicative of stigmatization toward people with selected substance and behavioral addictions.

The water demand for human activities is rapidly increasing in developing countries. Under these circumstances, preserving aquatic ecosystems should be a priority which requires the development of quality criteria. In this study we perform a preliminary prioritization of the risky substances based on reported ecotoxicological studies and guidelines for the Biobío watershed (Central Chile). Our specific aims are (1) reviewing the scientific information on the aquatic pollution of this watershed, (2) determining the presence and concentration of potential toxic substances in water, sediment and effluents, (3) searching for quality criteria developed by other countries for the selected substances and (4) prioritizing the most risky substances by means of deterministic ecotoxicological risk assessment. We found that paper and mill industries were the main sources of point pollution, while forestry and agriculture were mostly responsible for non-point pollution. The most risky organic substances in the water column were pentachlorophenol and heptachlor, while the most relevant inorganic ones were aluminum, copper, unionized ammonia and mercury. The most risky organic and inorganic substances in the sediment were phenanthrene and mercury, respectively. Our review highlights that an important effort has been done to monitor pollution in the Biobío watershed. However there are emerging pollutants and banned compounds-especially in sediments-that require to be monitored. We suggest that site-specific water quality criteria and sediment quality criteria should be developed for the Biobío watershed, considering the toxicity of mixtures of chemicals to endemic species, and the high natural background level of aluminum in the Biobío.

Tackling drug and alcohol misuse in Brazil: priorities and challenges for nurses.

PubMed

Rassool, G H; Villar-Luis, M

2004-12-01

To provide an overview of the extent of drug and alcohol misuse in Brazil and the policies and approaches in tackling substance misuse. An examination of the challenges facing the nursing profession in working with substance misusers is presented. Alcohol, cocaine, and cannabis are the most commonly misused psychoactive substances in Brazil. One of the biggest public health problems is the interface between the misuse of psychoactive substances and HIV prevalence and other sexually transmitted diseases. Findings from a recent study suggest that undergraduate nurses in Brazil are not adequately prepared in the care and management of substance misuse problems. The nursing profession in Brazil faces numerous challenges in the development of professional competence of nurses in this field. A strategy proposed is the creation of regional centres in Brazil to study the integration of substance use and misuse in the nursing undergraduate curriculum and the giving of specific support in teaching and research to nurse teachers. Nurses have a key role to play in the early recognition, assessment, prevention, and treatment of substance misuse.

Is there an association between adolescent bullying victimization and substance abuse?

2012-01-01

Bullying is endemic in the nation's schools and takes a substantial toll on its victims' physical and social-emotional well-being. We assessed the association between specific reasons for which adolescents believe that they are targeted for bullying and their rates of various types of substance use by analyzing the association between self-reported past 30-day substance use and past 30-day bullying victimization among 53,750 middle and high school students in Oregon. Our results confirm previous estimates of prevalence rates for bullying as well as modest (r < 0.20) associations between bullying victimization and substance use. However, study findings did not reveal a particular reason for bullying victimization that would place adolescents at a relatively high risk of substance use.

Age-Specific Associations Between Violence Exposure and Past 30-Day Marijuana and Alcohol Use.

2018-04-23

Using data from a cohort study of students at risk for high school dropout, we examined associations between violence exposure and past 30-day alcohol and marijuana use. We used varying-coefficient regression with person-level fixed effects to estimate how those associations changed within-person across ages approximately 14-23. Generally, violence perpetration was most strongly associated with substance use, within-person. Substance use became increasingly associated with both observed violence and violence perpetration during early/middle adolescence; this increase continued longer into development (age 18+) for alcohol use. Across most of the age range studied here, violence victimization was minimally associated with within-person changes in substance use. Results indicate age-specific associations between violence exposure and alcohol and other drug use, which may be useful for informing prevention strategies. © 2018 Society for Research on Adolescence.

DSM-5 cannabis use disorder, substance use and DSM-5 specific substance-use disorders: Evaluating comorbidity in a population-based sample.

PubMed

Hayley, Amie C; Stough, Con; Downey, Luke A

2017-08-01

Cannabis use disorder (CUD) is frequently associated with concurrent substance use and/or comorbid substance use disorders (SUDs); however there is little specificity with regard to commonly abused individual drug types/classes. This study therefore aimed to provide insight into the degree of these co-occurring relationships across several specific newer and older generation illicit and prescription drugs. 36,309 adults aged 18+ from wave 3 of the National Epidemiologic Survey on Alcohol and Related Conditions (NESARC-III) were assessed. Weighted cross-tabulations and multivariable logistic regression analyses were used to evaluate comorbidity between current DSM-5 CUD, substance use and DSM-5 SUD. Current DSM-5 CUD is associated with greater lifetime use of all examined drug classes, and previous 12-month use of several newer-class illicit and prescription stimulant-based substances (all p< 0.05). Current DSM-5 CUD was similarly associated with increased incidence of a range of DSM-5 SUDs and was independently associated with concurrently reporting current DSM-5; sedative (Adjusted OR= 5.1, 95%CI 2.9-9.0), cocaine (AOR= 9.3, 95%CI 5.6-15.5), stimulant (AOR= 4.3, 95%CI 2.3-7.9), club drug (AOR= 16.1, 95%CI 6.3-40.8), opioid (AOR= 4.6, 95%CI 3.0-6.8) and alcohol-use disorder (AOR= 3.0, 95%CI 2.5-3.7); but not heroin or 'other' drug use disorder (both p>0.05). High comorbidity exists between DSM-5 CUD and many specific DSM-5 SUDs. Newer-class illicit and prescription stimulant-based drug use disorders are overrepresented among those with DSM-5 CUD. These findings underscore the need for tailored treatment programs for those presenting with DSM-5 CUD, and for greater treatment specification where poly-drug use is evident.

The effect of parental alcohol and drug disorders on adolescent personality.

PubMed

Elkins, Irene J; McGue, Matt; Malone, Steve; Iacono, William G

2004-04-01

The relationship of parental alcohol or drug diagnosis to offspring personality was examined in a population-based sample of 17-year-old twins (568 girls and 479 boys) participating in the Minnesota Twin Family Study. Whether offspring personality characteristics 1) are specific to the type of substance use disorder in parents (alcohol versus drug) and 2) are found in high-risk offspring without substance use disorders as well as in offspring with substance use disorders was investigated. Personality was assessed with the Multidimensional Personality Questionnaire; substance use disorders were assessed in person through diagnostic interviews. In both male and female offspring, parental history of alcohol dependence was associated with greater negative emotionality, aggression, stress reaction, and alienation but lower well-being; parental history of drug disorders was associated with lower constraint, control, harm avoidance, and traditionalism but higher social potency. Excluding offspring with a substance use disorder had virtually no effect on the statistical significance of these findings. In contrast to findings in some adult samples, personality characteristics associated with a family history of substance use disorders are found even in adolescent offspring who have not yet developed these disorders themselves, suggesting that personality might be one indicator of familial risk for substance use disorders during this developmental stage. Personality profiles of offspring of parents with substance use disorders also show some diagnostic specificity, with constraint associated with parental drug abuse and negative emotionality with parental alcoholism.

Aim To address an urgent need for screening of substance use problems in medical settings, we examined substance-specific dependence criteria as potential brief screeners for the detection of patients with a substance use disorder (SUD). Methods The sample included 920 opioid-dependent adults who were recruited from outpatient treatment settings at 11 programs in 10 U.S. cities and who completed intake assessments of SUDs for a multisite study of the National Drug Abuse Treatment Clinical Trials Network (CTN003). Data were analyzed by factor analysis, item response theory (IRT), sensitivity, and specificity procedures. Results Across all substances (alcohol, amphetamines, cannabis, cocaine, sedatives), withdrawal was among the least prevalent symptoms, while taking large amounts and inability to cut down were among the most prevalent symptoms. Items closely related to the latent trait of a SUD showed good-to-high values of area under the receiver operating characteristic curve in identifying cases of a SUD; IRT-defined severe and less discriminative items exhibited low sensitivity in identifying cases of a SUD (withdrawal for all substances; time using for alcohol and sedatives; giving up activities for sedatives). Conclusions Study results suggest that withdrawal and time using are much less reliable indicators for a SUD than taking larger amounts than intended and inability to cut down and should be studied further for consideration in developing a simplified tool for screening patients for SUDs in medical settings. These findings have implications for the use of common health indicators in electronic health records systems to improve patient care. PMID:22204775

Substance-related expectancies are associated with substance use and post-substance use thoughts, feelings and behaviours. The expectancies held by specific cultural or sub-cultural groups have rarely been investigated. This research maps expectancies specific to gay and other men who have sex with men (MSM) and their relationship with substance patterns and behaviours following use, including sexual practices (e.g., unprotected anal intercourse). This study describes the development of a measure of such beliefs for cannabis, the Cannabis Expectancy Questionnaire for Men who have Sex with Men (CEQ-MSM). Items selected through a focus group and interviews were piloted on 180 self-identified gay or other MSM via an online questionnaire. Factor analysis revealed six distinct substance reinforcement domains ("Enhanced sexual experience", "Sexual negotiation", "Cognitive impairment", "Social and emotional facilitation", "Enhanced sexual desire", and "Sexual inhibition"). The scale was associated with consumption patterns of cannabis, and in a crucial test of discriminant validity not with the consumption of alcohol or stimulants. The CEQ-MSM represents a reliable and valid measure of outcome expectancies, related to cannabis among MSM. Future applications of the CEQ-MSM in health promotion, clinical settings and research may contribute to reducing harm associated with substance use among MSM, including HIV transmission.

Previous studies have shown that when assessing child psychopathology, parents tend to report more symptoms than children for externalizing disorders such as attention deficit hyperactivity disorder (ADHD), whereas children tend to report more symptoms for internalizing disorders such as major depression. Whether for clinical or research purposes, parents are also frequently asked to report on their children's experiences with alcohol and drugs. The purpose of this study was to analyze correspondence between adolescent and parent reports of adolescent substance use and abuse or dependence. In the current study, 591 subjects 12 to 17 years old were interviewed using the child version of the Semi-Structured Assessment for the Genetics of Alcoholism (C-SSAGA) as part of the Collaborative Study on the Genetics of Alcoholism (COGA). One parent was also interviewed about each adolescent using the parent version of the C-SSAGA. Sensitivities, specificities, and kappa coefficients were calculated to assess parental agreement with adolescent reports of lifetime substance use and Diagnostic and Statistical Manual of Mental Disorders-Third Revision substance abuse or dependence. The results indicate that parents are somewhat knowledgeable about their children's use of substances, particularly those that are used most commonly. For example, 55% of adolescents who had smoked cigarettes, 50% who had used alcohol, and 47% who had used marijuana had a parent who knew that they used. However, parents were less aware of substance-related problems experienced by their offspring, agreeing with adolescent reports only 27% of the time for diagnoses of alcohol abuse or dependence and 26% of the time for diagnoses of marijuana abuse or dependence. Parent reports added few cases of substance use for 12- to 13 year-olds and essentially no cases for 16- to 17-year-olds. Parent reports added a nominal number of diagnoses of substance abuse or dependence for older adolescents. Whether for clinical or research purposes, the results emphasize the importance of directly assessing adolescents regarding alcohol and other substance use disorders. Furthermore, investigators should consider the specific disorder(s) being investigated and the ages of the children being studied when determining whether to include parent reports as part of study design.

On the importance of distinguishing shame from guilt: Relations to problematic alcohol and drug use

Previous research has demonstrated that shame-proneness (the tendency to feel bad about the self) relates to a variety of life problems, whereas guilt-proneness (the tendency to feel bad about a specific behavior) is more likely to be adaptive. The current analyses sought to clarify the relations of shame-proneness and guilt-proneness to substance use problems in three samples with differing levels of alcohol and drug problem severity: college undergraduates (Study 1 N =235, Study 2 N =249) and jail inmates (Study 3 N =332). Across samples, shame-proneness was generally positively correlated with substance use problems, whereas guilt-proneness was inversely related (or unrelated) to substance use problems. Results suggest that shame and guilt should be considered separately in the prevention and treatment of substance misuse. PMID:16022935

Physiological correlates of behavioral and emotional problems, substance use onset and initiation of risky sexual behavior have not been studied in adolescents with prenatal drug exposure. We studied the concordance between baseline respiratory sinus arrhythmia (RSA) at age 3 and baseline cortisol levels at age 11. We hypothesized that children who showed concordance between RSA and cortisol would have lower neurobehavioral disinhibition scores which would in turn predict age of substance use onset and first sexual intercourse. The sample included 860 children aged 16 years participating in the Maternal Lifestyle Study, a multisite longitudinal study of children with prenatal exposure to cocaine and other substances. Structural equation modeling was used to test pathways between prenatal substance exposure, early adversity, baseline RSA, baseline cortisol, neurobehavioral disinhibition, drug use, and sexual behavior outcomes. Concordance was studied by examining separate male and female models in which there were statistically significant interactions between baseline RSA and cortisol. Prenatal substance exposure was operationalized as the number of substances to which the child was exposed. An adversity score was computed based on caregiver postnatal substance use, depression and psychological distress, number of caregiver changes, socioeconomic and poverty status, quality of the home environment, and child history of protective service involvement, abuse and neglect. RSA and cortisol were measured during a baseline period prior to the beginning of a task. Neurobehavioral disinhibition, based on composite scores of behavioral dysregulation and executive dysfunction, substance use and sexual behavior were derived from questionnaires and cognitive tests administered to the child. Findings were sex specific. In females, those with discordance between RSA and cortisol (high RSA and low cortisol or low RSA and high cortisol) had the most executive dysfunction which, in turn, predicted earlier initiation of alcohol by age 16. Among boys, there also existed a significant baseline RSA by baseline cortisol interaction. Boys with low baseline RSA and high baseline cortisol had the highest levels of behavioral dysregulation. This increase in behavioral dysregulation was in turn related to initiation of alcohol use by age 16 and lower age of first sexual intercourse. We found sex-specific pathways to the initiation of alcohol use and risky sexual behavior through the combined activity of parasympathetic and neuroendocrine functioning. The study of multiple physiological systems may suggest new pathways to the study of age of onset of substance use and engagement in risky sexual behavior in adolescents. © 2014 S. Karger AG, Basel.

This paper presents two replications of a heuristic model for measuring environment in studies of gene-environment interplay in the etiology of young adult problem behaviors. Data were drawn from two longitudinal, U.S. studies of the etiology of substance use and related behaviors: the Raising Healthy Children study (RHC; N=1040, 47% female) and the Minnesota Twin Family Study (MTFS; N=1512, 50% female). RHC included a Pacific Northwest, school-based, community sample. MTFS included twins identified from state birth records in Minnesota. Both studies included commensurate measures of general family environment and family substance-specific environments in adolescence (RHC ages 10-18; MTFS age 18), as well as young adult nicotine dependence, alcohol and illicit drug use disorders, HIV sexual risk behavior, and antisocial behavior (RHC ages 24, 25; MTFS age 25). Results from the two samples were highly consistent and largely supported the heuristic model proposed by Bailey et al. (2011). Adolescent general family environment, family smoking environment, and family drinking environment predicted shared variance in problem behaviors in young adulthood. Family smoking environment predicted unique variance in young adult nicotine dependence. Family drinking environment did not appear to predict unique variance in young adult alcohol use disorder. Organizing environmental predictors and outcomes into general and substance-specific measures provides a useful way forward in modeling complex environments and phenotypes. Results suggest that programs aimed at preventing young adult problem behaviors should target general family environment and family smoking and drinking environments in adolescence.

Prevalence and Correlates of Substance Use in Homeless Youth and Young Adults.

PubMed

Santa Maria, Diane M; Narendorf, Sarah C; Cross, Matthew B

Substance use is higher among homeless youth than among the general population. Although substance use has been well studied, little is known about the risk factors associated with specific substances used by homeless youth, particularly in the Houston, Texas, area. Therefore, we conducted this study to examine the rates of lifetime and past-month substance use in a sample of homeless youth in Harris County, Texas, and examine the relations between substance type and race/ethnicity, age, gender identity, sexual orientation, shelter status, stress, and trauma history. Participants were recruited during October and November 2014 as part of the study YouthCount 2.0! and completed a survey to assess demographics, stress, abuse, substance use, and risk behaviors. The sample (N = 416) was predominantly young adult (13-17 years old: 55 and 18-24 years old: 361), African American (54.5%), and male (55.9%). Nearly one quarter identified as lesbian, gay, bisexual, or questioning (n = 102). Over a third of youth had used alcohol (38%) or marijuana (36%) in the past month, and 36% had ever used synthetic marijuana. Bivariate analyses showed that substance use was significantly associated with race/ethnicity, age, gender identity, sexual orientation, shelter status, stress, and trauma scores. Youth in this study had lower rates of alcohol and some substance use than other samples of homeless youth, although use still exceeded national rates for housed youth. Substance use prevention interventions for homeless youth should be trauma informed and include housing navigation and stress management strategies. The most at-risk subgroups included street-dwelling and lesbian, gay, bisexual, or questioning youth.

Objective: Although recovery increasingly guides substance use disorder services and policy, definitions of recovery continue to lack specificity, thereby hindering measure development and research. The goal of this study was to move the substance use disorders field beyond broad definitions by empirically identifying the domains and specific elements of recovery as experienced by persons in recovery from diverse pathways. Method: An Internet-based survey was completed by 9,341 individuals (54% female) who self-identified as being in recovery, recovered, in medication-assisted recovery, or as having had a problem with alcohol or drugs (but no longer do). Respondents were recruited via extensive outreach with treatment and recovery organizations, electronic media, and self-help groups. The survey included 47 recovery elements developed through qualitative work followed by an iterative reduction process. Exploratory and confirmatory factor analyses were conducted using split-half samples, followed by sensitivity analyses for key sample groupings. Results: Four recovery domains with 35 recovery elements emerged: abstinence in recovery, essentials of recovery, enriched recovery, and spirituality of recovery. The four-factor structure was robust regardless of length of recovery, 12-step or treatment exposure, and current substance use status. Four uncommon elements did not load on any factor but are presented to indicate the diversity of definitions. Conclusions: Our empirical findings offer specific items that can be used in evaluating recovery-oriented systems of care. Researchers studying recovery should include measures that extend beyond substance use and encompass elements such as those examined here—e.g., self-care, concern for others, personal growth, and developing ways of being that sustain change in substance use.

[Substance use, affective problems and personality traits: test of two association models].

PubMed

Chakroun, N; Doron, J; Swendsen, J

2004-01-01

The International Consortium of Psychiatric Epidemiology has confirmed the high comorbidity in community-drawn samples between substance use disorders and anxiety or depression. In the same way, associations between substance use and specific personality traits (such as novelty seeking, harm avoidance or antisocial personality) have also been extensively documented. Self-medication and social deviance are among the most commonly evoked explanatory models for these forms of comorbidity, and are based on findings that affective disorders and specific personality traits often precede the onset of substance use disorders. The self-medication model postulates that an individual chooses a specific substance according to its psychopharmacologic action on the given psychological state of the person. By contrast, the social deviance model posits that this form of comorbidity is due to the fact that persons consuming certain substances may have affective or personality characteristics that are more severe or more deviant than non-consumers (or than consumers of socially well-accepted substances). In this way, the individual does not use a particular substance to assuage pre-existing disorders but, due to a more deviant personality, is less influenced by social norms and may more easily turn to using illicit substances or to polyconsumption. However, a major limitation of the current scientific literature concerning tests of these models is that previous investigations have been based in overwhelming majority on clinical populations. The examination only of clinical samples renders difficult the identification of causal (or primary) risk factors for the emergence of substance use disorders from the potential consequences of substance use itself. The goal of the current study was therefore to simultaneously compare both models of association using a non clinical population of substance users. In addition to selecting subjects based on use (rather than abuse or dependence), multiple comparisons were corrected with a Bonferroni adjustment. A two-phase sampling plan was used with post-stratification on substances use. In the first stage, an initial sample of 685 students was pre-selected based on responses to a battery of self-questionnaires, including information concerning recent consumption of substances (alcohol, cannabis, cocaine, heroin, acid, solvents, and so on), anxiety levels measured by the State and Trait Anxiety Inventory (STAI, Spielberger, 1983) and depression levels evaluated by the Center of Epidemiologic Studies Depression Scale (CES-D, Radloff, 1977). Based on responses to these questionnaires, 98 subjects were selected in the second phase to compose four groups of substance users: non consumers (those who did not use any substance during the last month); consumers of alcohol only, consumers of cannabis (with or without alcohol) and consumers of other illicit substances (with or without cannabis or alcohol). These subjects were then invited to participate in a brief laboratory-based meeting where they completed the Temperament and Character Inventory (TCI, Cloninger, 1992), which assessed different personality characteristics such as novelty seeking (NS), harm avoidance (HA) or antisocial personality disorder (APD). The hypotheses concerning self-medication were tested by multiple logistic regression by comparing each group of substance consumption to the non-consumer group relative to levels of anxiety, depression and scores of novelty seeking and harm avoidance. The social deviance model was tested by ANOVAs using contrasts which allowed for a test of a linear tendency across the four groups of consumption relative to each of the personality traits (novelty seeking, harm avoidance and antisocial personality). Results of multiple logistic regressions showed no difference between non-consumers and any group of consumers with regard to anxiety, depression and harm avoidance. However, consumers of other illicit substances significantly differed from non-consumers for novelty seeking trait (qOR=8.4; p<0.05). Results of the ANOVA also showed no differences between the four groups with regard to scores of harm avoidance and level of antisocial personality but again a comparison of novelty seeking scores was significant, F(94)=6.46, p<0.05. Moreover, the contrast method demonstrated that novelty seeking scores increased linearly and significantly (p<0.001) from the group of non-consumers to the group of the consumers of the most deviant substances. The results obtained in this non-clinical sample are in favor of social deviance model which posits that the personality trait of novelty seeking is associated to the consumption of the most illicit and deviant substances (such as heroin or cocaine). On the other hand, no support was found for the hypothesis of self-medication which assumes that specific substances should be particularly associated with specific psychological characteristics or vulnerabilities.

Precursors of dangerous substances formed in the loss of control of chemical systems.

Cozzani, V; Zanelli, S

Article 2 of Directive 96/82/EC on the control of major accident hazards caused by dangerous substances requires to consider also the hazards due to the dangerous substances "which it is believed may be generated during loss of control of an industrial chemical process", although no generally accepted guidelines are available for the identification of these substances. In the present study, the accidents involving the unwanted formation of dangerous substances as a consequence of the loss of control of chemical systems were investigated. A specifically developed database was used, containing data on more than 400 of these accidents and on the substances involved. The hazardous substances formed in the accidents and the precursors of these substances were identified. The influence of accident characteristics on the substances formed was investigated. In the context of the application of Directive 96/82/EC, an accident severity index and a hazard rating of the precursors of dangerous substances formed in the accidents were proposed. A lumping approach was used in order to develop schemes for the preliminary identification of substances that may be formed in the loss of control of chemical system. The results of accident analysis were used to test the schemes developed.

Adolescent substance use in Israel: The roles of exposure to political traumas and posttraumatic stress symptoms.

PubMed

Schiff, Miriam; Fang, Lin

2014-06-01

Previous studies have not examined the potential mediating role of posttraumatic stress symptoms (PTS) and moderating roles of gender and ethnicity among adolescents in the aftermath of political traumas, especially in the Middle East. This study of Israeli adolescents aimed to begin bridging these gaps in knowledge. We addressed the following hypotheses: (a) greater exposure to multiple political traumas would be associated with adolescent substance use; (b) greater PTS would be associated with adolescent substance use; (c) PTS would mediate the association of exposure to multiple political traumas on substance use; and (d) gender and ethnicity would moderate the pathways from exposure and PTS to substance use. A nationally representative sample included 4,733 Grade 10 and 11 students (half were females; 36.8% were Arabs). Results of bootstrapping estimations found a significant direct link between exposure to multiple political traumas and substance use, as well as an indirect link through PTS. Gender moderated the relationship between PTS and substance use, while ethnicity moderated the association between exposure and substance use. Specifically, female adolescent substance use decreased when their PTS increased. Arab adolescents who had greater exposure to multiple political traumas used more substances. PTS may be an important mechanism by which trauma exposure is associated with increased substance use. Screening adolescents for PTS and substance use, shortly after political trauma, is essential to address the potential risk factors in vulnerable adolescents.

The soundtrack of substance use: music preference and adolescent smoking and drinking.

A connection between preferences for heavy metal, rap, reggae, electronic dance music, and substance use has previously been established. However, evidence as to the gender-specific links between substance use and a wider range of music genres in a nationally representative sample of adolescents has to date been missing. In 2003, the Dutch government funded the Dutch National School Survey on Substance Use (DNSSSU), a self-report questionnaire among a representative school-based sample of 7,324 adolescents aged 12 to 16 years, assessed music preference, tobacco, and alcohol use and a set of relevant covariates related to both substance use and music preference. Overall, when all other factors were controlled, punk/hardcore, techno/hardhouse, and reggae were associated with more substance use, while pop and classical music marked less substance use. While prior research showed that liking heavy metal and rap predicts substance use, in this study a preference for rap/hip-hop only indicated elevated smoking among girls, whereas heavy metal was associated with less smoking among boys and less drinking among girls. The types of music that mark increased substance use may vary historically and cross-culturally, but, in general, preferences for nonmainstream music are associated positively with substance use, and preferences for mainstream pop and types of music preferred by adults (classical music) mark less substance use among adolescents. As this is a correlational study no valid conclusions in the direction of causation of the music-substance use link can be drawn.

2014-01-01

Background: Several studies have examined the prevalence and pattern of substance use among medical students in Nigeria. Few of these studies have specifically examined the relationship between the psychological distress and psychoactive substance use among these students. Yet, evidence world-wide suggests that substance use among medical students might be on the rise and may be related to the level of stress among them. Aim: The present study is the first study aimed to determine the prevalence, pattern and factors associated with psychoactive substance use among medical students of Olabisi Onabanjo University, Ogun State, Nigeria. Subjects and Methods: The World Health Organization student drug use questionnaire was used to evaluate for substance use among 246 clinical medical students between September and October 2011. General health questionnaire (GHQ) 12 was used to assess for psychological distress among these students. Statistical analysis was performed using the SPSS version 16. (Chicago, USA). Proportions were compared using the Chi-square test while a value of P < 0.05 was considered statistically significant. Fisher exact test was used instead of Chi-square when the number in the cell is less than 5. Results: Lifetime prevalence of substance use among medical students was 65% (165/246). It was found that the most commonly used substances were alcohol 63.4% (156/246), mild stimulants 15.6% (38/246), tobacco 15% (37/246) and sedatives 6.1% (15/246). Substance use was associated with gender, frequency of participation in religious activities and GHQ scores. Conclusion: Psychoactive substance use is a major problem among medical students. Psychological well-being plays a significant role in substance use among these students. There is a need for adequate screening and assessment for substance use disorders among these students and incorporating stress management strategies in their curriculum. PMID:24971216

Identifying specific aspects of peer social norms that influence adolescent substance use may assist international prevention efforts. This study examines two aggregated measures of social norms in the school setting and their predictive association with substance (alcohol, tobacco and marijuana) use 2 years later in a large cross-national population-based cohort of adolescents. The primary hypothesis is that in Grade 7 both “injunctive” school norms (where students associate substance use with “coolness”) and “descriptive” norms (where student substance use is common) will predict Grade 9 substance use. Data come from the International Youth Development Study, including 2,248 students (51.2 % female) in the US and Australia attending 121 schools in Grade 7. Independent variables included injunctive norms (aggregating measures of school-wide coolness ratings of each substance use) and descriptive norms (aggregating the prevalence of school substance use) in Grade 7. Dependent variables included binge drinking and current use of alcohol, tobacco and marijuana in Grade 9. Associations between each type of school-wide social norm and substance use behaviors in Grade 9 were tested using multilevel logistic regression, adjusting for covariates. In unadjusted models, both injunctive and descriptive norms each significantly predicted subsequent substance use. In fully adjusted models, injunctive norms were no longer significantly associated with Grade 9 use, but descriptive norms remained significantly associated with tobacco and marijuana use in the expected direction. The findings identify descriptive social norms in the school context as a particularly important area to address in adolescent substance use prevention efforts. PMID:24633850

Validation of the 4P's Plus screen for substance use in pregnancy validation of the 4P's Plus.

2007-12-01

The purpose of this study is to validate the 4P's Plus screen for substance use in pregnancy. A total of 228 pregnant women enrolled in prenatal care underwent screening with the 4P's Plus and received a follow-up clinical assessment for substance use. Statistical analyses regarding reliability, sensitivity, specificity, and positive and negative predictive validity of the 4Ps Plus were conducted. The overall reliability for the five-item measure was 0.62. Seventy-four (32.5%) of the women had a positive screen. Sensitivity and specificity were very good, at 87 and 76%, respectively. Positive predictive validity was low (36%), but negative predictive validity was quite high (97%). Of the 31 women who had a positive clinical assessment, 45% were using less than 1 day per week. The 4P's Plus reliably and effectively screens pregnant women for risk of substance use, including those women typically missed by other perinatal screening methodologies.

Since DSM-IV was published in 1994, its approach to substance use disorders has come under scrutiny. Strengths were identified (notably, reliability and validity of dependence), but concerns have also arisen. The DSM-5 Substance-Related Disorders Work Group considered these issues and recommended revisions for DSM-5. General concerns included whether to retain the division into two main disorders (dependence and abuse), whether substance use disorder criteria should be added or removed, and whether an appropriate substance use disorder severity indicator could be identified. Specific issues included possible addition of withdrawal syndromes for several substances, alignment of nicotine criteria with those for other substances, addition of biomarkers, and inclusion of nonsubstance, behavioral addictions. This article presents the major issues and evidence considered by the work group, which included literature reviews and extensive new data analyses. The work group recommendations for DSM-5 revisions included combining abuse and dependence criteria into a single substance use disorder based on consistent findings from over 200,000 study participants, dropping legal problems and adding craving as criteria, adding cannabis and caffeine withdrawal syndromes, aligning tobacco use disorder criteria with other substance use disorders, and moving gambling disorders to the chapter formerly reserved for substance-related disorders. The proposed changes overcome many problems, while further studies will be needed to address issues for which less data were available. PMID:23903334

To investigate the direct effect of different childhood difficulties on adult intelligence coefficient (IQ) and their possible indirect effect through the mediating pathways of education and severity substance use. Ninety in-patients aged 19-64. The participants had abstained from substance use for at least 6 weeks and had different substance use profiles. Substance use disorder (SUD) and psychiatric illnesses were diagnosed according to the International Classification of Diseases 10th edition criteria. IQ was measured with the Wechsler Adult Intelligence Scale, 4th edition. Childhood difficulties, severity of substance use and level of education were assessed through a self-report questionnaire. Mean full scale IQ for the studied population was 87.3. Learning and attention deficit/hyperactivity difficulties in childhood were directly related to adult IQ. Education had a mediating effect between childhood learning difficulties/conduct problems and the verbal comprehension index. There was no significant difference in IQ due to the specific substance used or severity of substance use. IQ variance in in-treatment individuals with SUD was related to childhood functioning alone or through the mediator of education. Substance-related factors did not contribute to IQ variance. The results fit a normal theory of IQ development with commonly known risk factors and no disturbing effect of substance use. © 2018 S. Karger AG, Basel.

We assessed the prevalence, incidence, and correlates of substance use among Asian American individuals transitioning from adolescence to young adulthood. Data were obtained from the National Longitudinal Study of Adolescent Health, Wave II (1996) and Wave III (2001). Information on substance use was abstracted from a nationally representative sample of 1108 Asian Americans and Pacific Islanders (AAPIs) from both Waves. Weighted prevalence, incidence, and patterns of smoking, binge drinking, marijuana use, and other drug use were analyzed by sexual orientation and gender. Multiple logistic regression analyses were conducted to investigate the unique contribution of being a sexual minority in relation to four types of substance use by gender. A link between sexual orientation and substance use behaviors among AAPIs did not emerge until young adulthood. Significant increases in the incidence and prevalence of all four types of substance use (tobacco, binge drinking, marijuana, and other drugs) were found among sexual minority AAPIs. Specifically being an AAPI sexual minority young woman, compared with being a heterosexual young woman, a heterosexual young man, or a sexual minority young man, was significantly associated with substance use after controlling for demographic characteristics, problem behaviors, and substance use during adolescence. Also the highest prevalence of substance use was found among AAPI sexual minority women. These findings add greater urgency to addressing the role of sexual orientation in designing substance abuse programs.

Women and substance abuse: gender, age, and cultural considerations.

PubMed

Stevens, Sally J; Andrade, Rosi A C; Ruiz, Bridget S

2009-01-01

Historically, data has shown that a smaller percentage of women use alcohol and illicit substances compared to men, and that frequency of use has been lower among women compared to use among men. Although this data on usage may be true, researchers also acknowledge that substance use among women has been a hidden issue, one not realistically acknowledged by society, especially prior to the mid-1960s. Along with this, more recent data indicates that rates of substance use among women are increasing. Factors contributing to this increase in substance abuse have begun to receive considerable attention, and recent research suggests that many issues exist that are unique to substance use among women. The purpose of this article is to discuss gender specific considerations in women's substance abuse by examining the history of substance use among women; analyzing gender-specific factors, including physiological factors, trauma-related factors, mental health issues, and cultural considerations that impact on women's substance use; articulating treatment approaches for working with substance abusing women and girls; and providing recommendations for further research in this area.

Ecotoxicity of boric acid in standard laboratory tests with plants and soil organisms.

To verify the continuous sensitivity of ecotoxicological tests (mainly the test organisms), reference substances with known toxicity are regularly tested. Ideally, this substance(s) would lack specificity in its mode action, be bioavailable and readily attainable with cost-effective means of chemical characterization. Boric acid has satisfied these criteria, but has most recently been characterized as a substance of very high concern, due to reproductive effects in humans, thus limiting its recommendation as an ideal reference toxicant. However, there is probably no other chemical for which ecotoxicity in soil has been so intensively studied; an extensive literature review yielded lethal (including avoidance) and sublethal data for 38 taxa. The ecotoxicity data were evaluated using species sensitivity distributions, collectively across all taxa, and separately according to species type, endpoints, soil type and duration. The lack of specificity in the mode of action yielded broad toxicity among soil taxa and soil types, and provided a collective approach to assessing species sensitivity, while taking into consideration differences in test methodologies and exposure durations. Toxicity was species-specific with Folsomia candida and enchytraied species demonstrating the most sensitivity; among plants, the following trend occurred: dicotyledonous (more sensitive) ≫ monocotyledonous ≫ gymnosperm species. Sensitivity was also time and endpoint specific, with endpoints such as lethality and avoidance being less sensitive than reproduction effects. Furthermore, given the breadth of data and toxicity demonstrated by boric acid, lessons learned from its evaluation are discussed to recommend the properties required by an ideal reference substance for the soil compartment.

METHOD AND APPARATUS FOR TESTING THE PRESENCE OF SPECIFIC ATOMIC ELEMENTS IN A SUBSTANCE

Detection of specific atomic elements in a substance and particularly the applicability to well logging are discussed. The principal novelty resides in the determination of several of the auxiliary energy peaks in addition to the main energy peak of the gamma-ray energy spectrum of a substance and comparison of such peaks to the spectrum of the specific atomic element being tested for. thus resulting in identification of same. The invention facilitates the identification of specific elements even when in the presence of other elements having similar gamma energy spectra as to the main energy peaks.

Research indicates that risk factors cluster in the most vulnerable youth, increasing their susceptibility for adverse developmental outcomes. However, most studies of cumulative risk are cross-sectional or short-term longitudinal, and have been based on data from the United States or the United Kingdom. Using data from the Northern Finland Birth Cohort 1986 Study (NFBC1986), we examined cumulative contextual risk (CCR) at birth as a predictor of adolescent substance use and co-occurring conduct problems and risky sex to determine the degree to which CCR predicts specific outcomes over-and-above its effect on general problem behavior, while testing for moderation of associations by gender. Analyses of survey data from 6963 participants of the NFBC1986 followed from the prenatal/birth period into adolescence were conducted using structural equation modeling. CCR had long-term positive associations with first-order substance use, conduct problems, and risky sex factors, and, in a separate analysis, with a second-order general problem behavior factor. Further analyses showed that there was a positive specific effect of CCR on risky sex, over-and-above general problem behavior, for girls only. This study, conducted within the Finnish context, showed that CCR at birth had long-term general and specific predictive associations with substance use and co-occurring problem behaviors in adolescence; effects on risky sex were stronger for girls. Results are consistent with the hypothesis that early exposure to CCR can have lasting adverse consequences, suggesting the need for early identification and intervention efforts for vulnerable children.

Physician substance use by medical specialty.

1999-01-01

Self-reported past year use of alcohol, tobacco, marijuana, cocaine, and two controlled prescription substances (opiates, benzodiazepines); and self-reported lifetime substance abuse or dependence was estimated and compared for 12 specialties among 5,426 physicians participating in an anonymous mailed survey. Logistic regression models controlled for demographic and other characteristics that might explain observed specialty differences. Emergency medicine physicians used more illicit drugs. Psychiatrists used more benzodiazepines. Comparatively, pediatricians had overall low rates of use, as did surgeons, except for tobacco smoking. Anesthesiologists had higher use only for major opiates. Self-reported substance abuse and dependence were at highest levels among psychiatrists and emergency physicians, and lowest among surgeons. With evidence from studies such as this one, a specialty can organize prevention programs to address patterns of substance use specific to that specialty, the specialty characteristics of its members, and their unique practice environments that may contribute risk of substance abuse and dependence.

Age-related aspects of addiction

Koechl, Birgit; Unger, Annemarie; Fischer, Gabriele

2013-01-01

Research has shown that substance use, abuse and addiction are not limited to a specific age group. Problems related to substance addiction are an important cause of morbidity in the population aged 65 and above, especially the abuse of prescription drugs and legal substances. A lack of evidence-based studies and tailored treatment options for the aging population is evident. Appropriate and effective health-care is an important goal to improve health-related quality of life of elderly people. Research in the increasingly aging population needs to include an age- and gender-sensitive approach. PMID:22722821

Substance use and misuse is prevalent in emergency department (ED) populations. While the prevalence of substance use and misuse is reported, sex-specific trends in ED populations have not been documented. We set out to determine the sex-specific prevalence of ED patient substance use during this current epidemic. A retrospective electronic data abstraction tool, developed for quality-improvement purposes, was used to assess ED visits in 3 hospitals in northeastern Pennsylvania. All patients with ED diagnosis codes for substance use F10.000 through F 19.999 (excluding F17 codes for nicotine) were abstracted for network ED visits at all 3 hospitals. Data points included ED clinical enrollment site, primary substance used, sex, date of ED visit, disposition (including left without being seen, left against medical advice, discharged, admitted, and treatment in rehabilitation) for 18 months (January 1, 2016 through July 31, 2017). The categorical parameters of sex, clinical enrollment site, diagnosis, date of ED visit, and disposition status were summarized as a proportion of the subject group. Time series analysis was used to assess trends in substance use and misuse visits by patient sex. A total of 10,511 patients presented to the EDs during the study time period with a final diagnosis of a substance use-related reason and were included in the analysis. The mean age for these patients was 43.6 (SD 16.4) years, and the majority was male (65.6%, n = 6900). The most common substance in the final diagnosis for the ED visit was alcohol (54.3%; 95% CI, 53.3-55.2), followed by opioids (19.2%; 95% CI, 18.4-19.9) and cannabis (14.4%; 95% CI, 13.7-15.0). Females tended to be younger than males (42.4 years vs 44.3 years; P < 0.001), and were more likely to be discharged after the ED visit than males (36.1% vs 32.3%; P < 0.001). When exploring differences in age by sex and substance, males with a final diagnosis including alcohol- and cannabis-related issues were older than females, whereas females diagnosed with opioid-related reasons were older than males (41.3 vs 38.9 years; P < 0.001). There are sex-specific differences in prevalence of patients presenting with substance use in the ED setting. Copyright © 2018 Elsevier HS Journals, Inc. All rights reserved.

The prevalence of symptoms in HIV disease can be associated with HIV disease itself, comorbid illness, and/or antiretroviral therapy. Unhealthy substance use behaviors, particularly substance-use behaviors including heavy alcohol intake, marijuana use, other illicit drug use, and cigarette smoking, are engaged in by many HIV-positive individuals, often as a way to manage disease-related symptoms. This study is a secondary data analysis of baseline data from a larger randomized-controlled trial of an HIV/AIDS Symptom Management Manual. In the present study, the prevalence and characteristics of unhealthy substance use behaviors in relation to HIV/AIDS symptoms are examined. Subjects were recruited from a variety of settings which provide HIV/AIDS care and treatment. The mean age of the sample (n=775) was 42.8 years (SD=9.6) and nearly thirty-nine percent (38.5%) of the sample was female. The racial demographics of the sample were: 28% African American, 28% Hispanic, 21% White/Caucasian, 16% African from Kenya or South Africa, 1% Asian, and 5% self-described as “Other.” The mean number of years living with HIV was reported to be 9.1 years (SD=6.6).Specific self-reported unhealthy substance-use behaviors were use of marijuana (n= 111; 14.3%), cigarette smoking (n=355; 45.8%), heavy alcohol use (n= 66; 8.5%), and illicit drugs (n= 98; 12.6%). A subset of individuals who identified high levels of specific symptoms also reported significantly higher substance use behaviors including amphetamine and injection drug use in addition to heavy alcohol use, cigarette smoking, and marijuana use. Implications for clinical practice include assessment of self-care behaviors, screening for substance abuse, and education of persons related to self-management across the trajectory of HIV disease.

Domain-General and Domain-Specific Strategies for the Assessment of Distress Intolerance

PubMed Central

McHugh, R. Kathryn; Otto, Michael W.

2011-01-01

Recent research has provided evidence that distress intolerance—the perceived inability to tolerate distressing states—varies based on the domain of distress (e.g., pain, anxiety). Although domain-specific assessment strategies may provide information targeted to specific disorders or maladaptive behaviors, domain-general measures have the potential to facilitate comparisons across studies, disorders, and populations. The current study evaluated the utilization of self-report measures of distress intolerance as domain-general measures by examining their association with indices of behavioral avoidance and substance craving. Two groups of participants (N = 55) were recruited including a substance-dependent group and a comparison group equated based on the presence of an affective disorder. Results provided support for the validity of domain-general measures for assessing distress intolerance across varied domains. The importance of both domain-general and domain-specific measurement of distress intolerance is discussed. PMID:21823763

The Relationship between Childhood Maltreatment and Emotional Dysregulation in Self Mutilation: An Investigation among Substance Dependent Patients

PubMed Central

KARAGÖZ, Başak; DAĞ, İhsan

2015-01-01

Introduction The present study aims to examine the role of emotion dysregulation and childhood maltreatment in self mutilation (SM) of substance dependent patients. Specifically, the present study examined whether emotion dysregulation and its dimensions, and childhood maltreatment and its dimensions were associated with SM. The relationship between emotion dysregulation and childhood maltreatment was also investigated. Methods The sample of study consisted of 55 alcohol dependent and 24 opiate dependent patients (n=79). Substance dependence was diagnosed by means of the Structured Clinical Interview for DSM-IV-TR (SCID-I), Turkish version. Childhood Trauma Questionnaire (CTQ) and Difficulties in Emotion Regulation Scale (DERS) were used. Results Findings indicated that substance dependents with SM and without SM were differentiated in terms of overall emotion dysregulation. Results also suggest the relevance of three specific dimensions of emotion dysregulation to SM: Difficulties engaging in goal-directed behaviors when experiencing negative emotions, difficulties controlling impulsive behaviors when experiencing negative emotions, and limited access to effective emotion regulation strategies. These dimensions were predicted from childhood emotional maltreatment and neglect. It is also revealed that substance dependents with SM had higher points than those without SM on emotional childhood maltreatment and neglect, physical childhood maltreatment. Conclusion Results were supported by the literature suggested that self-mutilation functions as a emotional regulation strategy. Findings also suggested that self- mutilation is related to early relationships take place in family environment in which individuals grow up. PMID:28360668

Pharmacotherapeutics for substance-use disorders: a focus on dopaminergic medications

2015-01-01

Introduction Illicit substance-use is a substantial public health concern, contributing over $150 billion in costs annually to Americans. A complex disease, a substance-use disorder affects neural circuits involved in reinforcement, motivation, learning and memory, and inhibitory control. Areas covered The modulatory influence of dopamine in mesocorticolimbic circuits contributes to encoding the primary reinforcing effects of substances and numerous studies suggest that aberrant signaling within these circuits contributes to the development of a substance-use disorder in some individuals. Decades of research focused on the clinical development of medications that directly target dopamine receptors has led to recent studies of agonist-like dopaminergic treatments for stimulant-use disorders and, more recently, cannabis-use disorder. Human studies evaluating the efficacy of dopaminergic agonist-like medications to reduce reinforcing effects and substance-use provide some insight into the design of future pharmacotherapy trials. A search of PubMed using specific brain regions, medications, and/or the terms ‘dopamine’, ‘cognition’, ‘reinforcement’, ‘cocaine’, ‘methamphetamine’, ‘amphetamine’, ‘cannabis’, ‘treatment/pharmacotherapy’, ‘addiction/abuse/dependence’ identified articles relevant to this review. Expert opinion Conceptualization of substance-use disorders and their treatment continues to evolve. Current efforts increasingly focus on a strategy fostering combination pharmacotherapies that target multiple neurotransmitter systems. PMID:24033127

Social contexts of drug offers among American Indian youth and their relationship to substance use: an exploratory study.

PubMed

Kulis, Stephen; Okamoto, Scott K; Rayle, Andrea Dixon; Sen, Soma

2006-01-01

In this exploratory study the authors examined the social contexts of American Indian youths' encounters with drug offers and their relationship to substance use. Using an inventory of drug use-related problem situations developed specifically for American Indian youth, questionnaires were completed by 71 American Indian youth at public middle schools in a Southwest metropolitan area. Regression analyses highlight the importance of situational and relational contexts in understanding substance use among the youth in this sample. Exposure to drug offers through parents, other adults, cousins, friends and other peers was associated with different types of substance use. Exposure through parents was particularly salient in predicting the drug use of female respondents. The study underscores the need for development of culturally grounded prevention programs in schools, reservations, and nonreservation communities. Copyright (c) 2006 APA, all rights reserved.

Adverse childhood experiences in substance use disorder outpatients of a Lebanese addiction center.

Childhood adversities (CAs) are well reviewed in mental health and addiction research internationally. However, these variables have not been studied within the framework of addiction in the Middle East region. The present study reports the prevalence of Childhood Adversities in a sample of outpatients seeking treatment for Substance Use Disorder. We used the Adverse Childhood Experiences - International Questionnaire (ACE-IQ) to map out the prevalence of childhood adversities. The studied population was composed of a clinical outpatient sample that met criteria for substance use disorder (N = 144). Results indicated that almost all the sample reported having experienced at least 1 CA, whereby three quarters of the clinical sample reported experiencing 6 or more adversities. Childhood adversities are highly prevalent in a Lebanese substance use disorder population which raises the need for better screening strategies and more understanding of Adverse Childhood Experiences in this specific population.

Injection drug use is associated with suicide attempts but not ideation or plans in a sample of adolescents with depressive symptoms.

PubMed

Liu, Richard T; Case, Brady G; Spirito, Anthony

Based on the interpersonal theory of suicide, pain habituation that occurs with injection substance use may raise risk for a suicide attempt. The current study tested whether injection substance use, relative to painless routes of substance administration, was related to greater risk for suicide attempts. We also assessed whether this risk was specific to suicide attempts and not suicidal ideation or suicide plans. Data on 2095 substance-using adolescents aged 12-17 who endorsed clinically significant depression symptoms and answered questions on suicidal thoughts and behavior were drawn from the 2004-2011 National Survey on Drug Use and Health, a nationally representative household survey. Logistic regression analyses were conducted to assess the associations between injection substance use and suicidal ideation, plans, and attempts. Injection substance use was associated with suicide attempts (OR = 3.02, 95% CI = 1.75-5.23) but not ideation or plans. These findings were not accounted for by sex, age, race/ethnicity, family income, abuse and dependence symptoms, and depression symptoms. Among ideators, injection substance use was associated with suicide attempts (OR = 2.92, 95% CI = 1.58-5.06), but not plans. Among suicide planners, injection substance use was associated with suicide attempts (OR = 5.16, 95% CI = 1.88-14.17). Consistent with the interpersonal theory of suicide, adolescent injection drug use was associated with specific risk for suicide attempts but not ideation or planning. Hence, consideration of the manner in which adolescents use substances is important in evaluating suicide risk in this population. Copyright © 2014 Elsevier Ltd. All rights reserved.

Gender Differences in Patterns of Substance Use and Delinquency: A Latent Transition Analysis

Bright, Charlotte Lyn; Sacco, Paul; Kolivoski, Karen M.; Stapleton, Laura M.; Jun, Hyun-Jin; Morris-Compton, Darnell

2017-01-01

This study explores gender-specific patterns and transitions of adolescent substance use and delinquency in a sample of youths at ages 12, 15, and 18 (N = 803). Latent transition analysis identified “Primary Delinquent,” “Delinquency and Substance Use,” and “Low Risk” classes. Females were less likely to be in the “Primary Delinquent” class at age 12 than males. From 15 to 18, females were approximately equally likely to transition from “Primary Delinquent” to both other classes, whereas males were more likely to transition from “Primary Delinquent” to “Delinquency and Substance Use.” These gender differences in behavior can inform services.

Associations Between Ethnic Labels and Substance Use Among Hispanic/Latino Adolescents in Los Angeles

PubMed Central

Unger, Jennifer B; Thing, James; Soto, Daniel Wood; Baezconde-Garbanati, Lourdes

2014-01-01

Self-identification with ethnic-specific labels may indicate successful ethnic identity formation, which could protect against substance use. Alternatively, it might indicate affiliation with oppositional subcultures, a potential risk factor. This study examined longitudinal associations between ethnic labels and substance use among 1,575 Hispanic adolescents in Los Angeles. Adolescents who identified as Cholo or La Raza in 9th grade were at increased risk of past-month substance use in 11th grade. Associations were similar across gender and were not confounded by socioeconomic status, ethnic identity development, acculturation, or language use. Targeted prevention interventions for adolescents who identify with these subcultures may be warranted. PMID:24779500

Risk factors for substances use and misuse among young people in France: What can we learn from the Substance Use Risk Profile Scale?

PubMed

2016-06-01

The prevention of addictions in young people is a challenge for Mental and Public Health policies, and requires specific risk-screening tools. Specific personality traits, as assessed using the Substance Use Risk Profile Scale (SURPS), could play a key role in the onset and escalation of substance use. This study aimed to examine (1) measurement invariance across age and gender (2) the effects of age and gender on associations between SURPS scores and the most frequently-consumed substances. Analyses were based on the responses from 5069 participants (aged 14-20 years) from the 2011 ESPAD-France dataset. Substance-use outcomes were experimentation and current frequency of alcohol, tobacco and cannabis use, and drunkenness. Our approach, consisting in analysing measurement and structural invariance and interaction terms, established the stability of (i) SURPS profiles, and (ii) relationships between these scores and substance experimentation and use over a developmental period ranging from mid-adolescence to early adulthood. Measurement invariance across genders was also confirmed despite the absence of scalar invariance for 2 items. Significant interactions between gender and SURPS factors were established, highlighting differential vulnerability, especially concerning Hopelessness and experimentation of alcohol and drunkenness, or Impulsivity and tobacco experimentation. Finally, Anxiety Sensitivity could be protective against substance use, especially for cannabis in girls. Our results suggest the relevance of the SURPS to assess vulnerability towards drug use, and underline the need to consider gender differences in addiction risks. Copyright © 2016 The Authors.

Substance Use in Undergraduate Students With Histories of Attention-Deficit/Hyperactivity Disorder (ADHD): The Role of Impulsivity.

PubMed

Egan, Theresa E; Dawson, Anne E; Wymbs, Brian T

2017-08-24

Emerging adulthood (18-25 years old) is regarded as a time of identity exploration that includes a peak in risky behaviors, such as substance use and misuse. Attention-deficit/hyperactivity disorder (ADHD) is also associated with greater levels of risky behaviors, including substance use and misuse; however, there is a lack of research on substance use by emerging adults with ADHD, in particular the potential mechanisms that may facilitate this risk. The present study builds on the existing research regarding the association between ADHD and substance use by examining roles of multiple facets of impulsivity in facilitating this association during emerging adulthood. In a sample of 197 undergraduate students (24 students with an ADHD diagnostic history), we assessed for components of impulsivity (e.g., urgency, sensation-seeking) and rates of alcohol abuse, tobacco use, cannabis use, illicit drug use, and stimulant medication misuse within the past year. Findings indicate that facets of impulsivity, as a whole, explained the association between an ADHD diagnostic history and both illicit drug use and alcohol abuse such that students with ADHD histories tended to report higher levels of impulsivity, which increased risk of alcohol abuse and illicit drug use. Higher levels of specific facets of impulsivity, particularly negative urgency, also facilitated associations between having ADHD and engaging in most forms of substance use tested herein. Conclusions/Importance: Specific facets of impulsivity appear to be important mediators of the association between ADHD and substance use, and should be considered as potential targets of substance use interventions for this population.

The present study examines the diagnostic challenges of identifying ante-mortem illicit substance use in human postmortem cases. Substance use, assessed by clinical case history reviews, structured next-of-kin interviews, by general toxicology of blood, urine, and/or brain, and by scalp hair testing, identified 33 cocaine, 29 cannabis, 10 phencyclidine and 9 opioid cases. Case history identified 42% cocaine, 76% cannabis, 10% phencyclidine, and 33% opioid cases. Next-of-kin interviews identified almost twice as many cocaine and cannabis cases as Medical Examiner (ME) case histories, and were crucial in establishing a detailed lifetime substance use history. Toxicology identified 91% cocaine, 68% cannabis, 80% phencyclidine, and 100% opioid cases, with hair testing increasing detection for all drug classes. A cocaine or cannabis use history was corroborated by general toxicology with 50% and 32% sensitivity, respectively, and with 82% and 64% sensitivity by hair testing. Hair testing corroborated a positive general toxicology for cocaine and cannabis with 91% and 100% sensitivity, respectively. Case history corroborated hair toxicology with 38% sensitivity for cocaine and 79% sensitivity for cannabis, suggesting that both case history and general toxicology underestimated cocaine use. Identifying ante-mortem substance use in human postmortem cases are key considerations in case diagnosis and for characterization of disorder-specific changes in neurobiology. The sensitivity and specificity of substance use assessments increased when ME case history was supplemented with structured next-of-kin interviews to establish a detailed lifetime substance use history, while comprehensive toxicology, and hair testing in particular, increased detection of recent illicit substance use.

2008-11-01

The aim of the present study was to provide a profile of young people attending alcohol and other drug (AOD) treatment services in Aotearoa, New Zealand. Data were gathered from a clinical file search of 184 randomly selected young people aged 13-19 years who had attended one of eight youth AOD treatment services in New Zealand during 2003 or 2004. These services represented eight of the 11 youth-specific AOD services available to youth in New Zealand. Young people who attend youth-specific AOD services in New Zealand present with a range of complex needs including substance use and mental health issues, criminality, family conflict and disengagement from school. A total of 62.0% were male, 56.4% had criminal convictions, 40.6% had spent some time in Child, Youth and Family Services care and 53.8% were reported to have a coexisting substance use and mental health disorder. Low rates of reporting of substance use and mental health diagnoses in treatment files suggest that substance use and mental health disorders among this population are likely to be higher than those reported. This paper provides a unique profile of young people attending youth-specific AOD treatments in New Zealand. Such information is useful in informing treatment planning and funding and ensuring that service development occurs to specifically meet the complex needs of this patient group.

Behavioral interventions for dual-diagnosis patients.

PubMed

Goldsmith, R Jeffrey; Garlapati, Vamsi

2004-12-01

Dual diagnosis patients come to treatment with a variety of deficits,talents, and motivations. A biopsychosocial treatment plan involves multiple interventions, including medications, medical treatment, psychotherapy, family therapy, housing, and vocational rehabilitation. Treatment must be individualized and integrated, and this requires collaboration among a variety of health caregivers. There is empirical evidence that dual-diagnosis patients can be helped to stabilize, to remain in the community,and even to enter the workforce. Behavioral interventions are key ingredients to integrated and comprehensive treatment planning. There is no single model for dual disorders that explains why substance use and psychiatric illness co-occur so frequently. Mueser et al described four theoretical models accounting for the increased rates of comorbidity between psychiatric disorders and substance use disorders. They suggested that there could be a common factor that accounts for both, primary psychiatric disorder causing secondary substance abuse, primary substance abuse causing secondary psychiatric disorder, or a bidirectional problem, where each contributes to the other. There is evidence for each, although some are more compelling than others, and none is so compelling that it stands alone. Although family studies and genetic research could explain the common factor, no common gene has appeared. Antisocial personality disorder has been associated with very high rates of substance use disorders and mental illness; however, its prevalence is too low to explain most of the co-occurring phenomena. Common neurobiology, specifically the dopamine-releasing neurons in the mesolimbic system, also may be involved in mental illness, but this is not compelling at the moment. The Self-medication model is very appealing to mental health professionals, as an explanation for the secondary substance abuse model. Mueser et al suggest that three lines of evidence would be present to support this explanation: (1) patients would report beneficial effects of substance use on their symptoms; (2) epidemiology would report that a specific substance would be used by specific psychiatric disorders, and (3) psychiatric patients with severe symptoms would be more likely to abuse substances than those with mild symptoms. Unfortunately the research data do not support these. The primary substance abuse causing secondary psychiatric disorder model could be explained by neuronal kindling from substance-induced disorders. Patients who develop the psychiatric disorder after the substance use disorder do have a course of illness similar to those with a psychiatric disorder, but without substance use disorder. The bidirectional model is consistent with the tendency of disturbed teenagers to socialize with youth using alcohol and drugs; however, this model has not been tested rigorously in research studies. With such a disparate set of models, behavior interventions are conceptualized best as a multi-component program, a treatment plan that generates a problem list and devises an intervention to respond to each member of the list. This requires a talented, multi-disciplinary team or network that can assess carefully and package the interventions creatively, and dose the treatment components empathically to fit the patient's tolerance, motivation, and abilities.

Girls Just Want to Know Where to Have Fun: Preventing Substance Use Initiation in an Under-Resourced Community in South Africa Through HealthWise

This study examined how the perception of the availability of leisure opportunities may prevent substance use initiation through HealthWise, a school-based program focused on reducing risky behavior. In this study, we specifically focused on whether HealthWise increased student perceptions of leisure opportunities between 8th grade and 10th grade (N = 5610) in an under-resourced community in South Africa. Path analyses were used to test hypotheses. Given gender differences in substance use patterns, societal norms, and leisure opportunities in under-resourced communities, such as the townships of Cape Town, South Africa, it was especially important to examine associations within each gender. Results suggested that HealthWise directly reduced the likelihood of initiating alcohol and cigarette use and increased the amount of perceived leisure opportunities among girls but not boys. Perceived leisure opportunities mediated the effect of HealthWise on reducing the initiation of alcohol and cigarette use directly, and marijuana use indirectly, among girls but not boys. This is the first study to demonstrate how experimentally targeting leisure through an intervention can increase perceived leisure opportunities and thereby prevent early substance use initiation for a specific population. The importance of considering the context of gender, age, and location is discussed. PMID:27129478

2016-01-01

The variable number tandem repeats (VNTR) polymorphism of the dopamine D4 receptor gene (DRD4) has received considerable attention as a potential genetic contributor to addiction. However, is unclear whether the polymorphism is involved in developing general traits that lead to risky behavior or an intermediate phenotype more specific to substance use disorders. Association studies have produced equivocal results. To control for potential confounds, the present study examined whether the long variant of the DRD4 VNTR polymorphism (DRD4L) is associated with greater substance misuse in a homogenous clinical sample of youth with a disruptive behavior disorder (DBD). Fifty-one psychiatrically hospitalized adolescents (mean age = 14.86 years) with a DBD diagnosis were recruited as part of a larger study. Participants provided saliva samples for genotyping procedures after completing a diagnostic interview and an assessment battery. The odds of a substance use disorder diagnosis were significantly greater among DRD4L than DRD4S carriers (OR = 5.20, 95%CI:1.42-19.04, p = .01). Relative to DRD4S homozygotes, DRD4L carriers also reported greater marijuana use (t = -2.68, p = .01) and hard drug use (t = -2.26, p = .03). Although adolescents with DBDs are already at heightened risk for substance misuse, the present findings suggest that DRD4L further increases those odds. As differences persisted even among a psychiatrically homogenous sample of impulsive and risk-prone adolescents, the present findings suggest that DRD4L may be involved in the development of an intermediate phenotype specific to substance abuse (eg, cue-elicited craving). © American Academy of Addiction Psychiatry.

Prospective Association of Childhood Attention-deficit/hyperactivity Disorder (ADHD) and Substance Use and Abuse/Dependence: A Meta-Analytic Review

Lee, Steve S.; Humphreys, Kathryn L.; Flory, Kate; Liu, Rebecca; Glass, Kerrie

2011-01-01

Given the clinical and public health significance of substance disorders and the need to identify their early risk factors, we examined the association of childhood attention-deficit/hyperactivity disorder (ADHD) with substance use (e.g., nicotine, alcohol) and abuse/dependence outcomes (nicotine, alcohol, marijuana, cocaine, other). To strengthen a potential causal inference, we meta-analyzed longitudinal studies that prospectively followed children with and without ADHD into adolescence or adulthood. Children with ADHD were significantly more likely to have ever used nicotine and other substances, but not alcohol. Children with ADHD were also more likely to develop disorders of abuse/dependence for nicotine, alcohol, marijuana, cocaine, and other substances (i.e., unspecified). Sex, age, race, publication year, sample source, and version of the Diagnostic and Statistical Manual of Mental Disorders (DSM) used to diagnose ADHD did not significantly moderate the associations with substance outcomes that yielded heterogeneous effect sizes. These findings suggest that children with ADHD are significantly more likely to develop substance use disorders than children without ADHD and that this increased risk is robust to demographic and methodological differences that varied across the studies. Finally, few studies addressed ADHD and comorbid disruptive behavior disorders (DBD), thus preventing a formal meta-analytic review. However, we qualitatively summarize the results of these studies and conclude that comorbid DBD complicates inferences about the specificity of ADHD effects on substance use outcomes. PMID:21382538

Workplace Substance-Use Norms as Predictors of Employee Substance Use and Impairment: A Survey of U.S. Workers*

PubMed Central

Frone, Michael R.; Brown, Amy L.

2010-01-01

Objective: Although much research has explored the relation of substance-use norms to substance use among college students, much less research has focused on employed adults and the workplace as a social context for social norms regarding substance use. This study explored the relation of descriptive and injunctive workplace substance-use norms regarding alcohol and illicit drug use to employee substance use. Both alcohol use and illicit drug use were explored, as well as overall and context-specific use and impairment. Method: Data were collected from a national probability sample of 2,430 employed adults (55% female) using a random-digit-dial telephone survey. Overall employee alcohol and illicit drug use were assessed, as well as use before work, use and impairment during the workday, and use after work. Results: After controlling for a number of potential covariates, injunctive norms regarding workplace alcohol and illicit drug use predicted substance use and impairment overall and across all contexts of use. Descriptive norms predicted alcohol and illicit drug use before and during work, as well as workplace impairment. Conclusions: This study shows that both workplace injunctive and descriptive norms are important predictors of substance use in the U.S. workforce. There were two general patterns, however, that were consistent across both alcohol and illicit drug use. Social norms marketing campaigns, therefore, may be a useful way for employers to target employee substance use. The present results also helped to integrate the results of several prior studies that employed narrower samples and measures. PMID:20553660

Substance Abuse Recovery after Experiencing Homelessness and Mental Illness: Case Studies of Change Over Time

Padgett, Deborah K.; Smith, Bikki Tran; Tiderington, Emmy

2012-01-01

Objective This paper addresses how consumers with dual diagnosis, who were formerly homeless but are now living in supportive housing, understand their recovery from substance abuse (i.e., substance abuse or dependence). Specifically, this study examined: What can be learned about substance abuse recovery from consumers considered to be doing well; how past substance abuse fits into their present-day narratives; and how (if at all) policies of harm reduction versus abstinence are regarded as affecting recovery efforts. Methods As part of a federally-funded qualitative study, 38 individuals who met criteria for having achieved a measure of success in mental health recovery were purposively sampled from two supportive housing agencies – one using a harm reduction and the other an abstinence model. Researchers conducted in-depth interviews and used case study analysis, the latter including the development of case summaries and data matrices, to focus on substance abuse recovery in the larger context of participants’ lives. Results Recovery from substance abuse was depicted as occurring either through discrete decisions or gradual processes; achieving recovery was distinct from maintaining recovery. Emergent themes related to achievement included: (a) pivotal events and people (b) maturation, and (c) institutionalization. Central themes to maintaining recovery were: (a) housing, (b) self-help, and (c) the influence of significant others. Conclusions These findings capture a complex picture of overcoming substance abuse that largely took place outside of formal treatment and was heavily dependent on broader contexts. Equally important is that consumers themselves did not necessarily view substance abuse recovery as a defining feature of their life story. Indeed, recovery from substance abuse was seen as overcoming one adversity among many others during their troubled life courses. PMID:22962547

Risk factors for criminal recidivism - a prospective follow-up study in prisoners with substance abuse.

PubMed

Håkansson, Anders; Berglund, Mats

2012-08-15

Substance use in general has been shown to predict criminal recidivism. The present study aimed to examine potential predictors of criminal recidivism, including substance-specific substance use patterns, in prisoners with substance use. A cohort of prisoners with substance use problems (N = 4,152) were assessed with the Addiction Severity Index (ASI) in the Swedish criminal justice system. Clients were followed for an average of 2.7 years. Criminal recidivism was defined as any return to the criminal justice system. During follow-up, 69 percent (n = 2,862) returned to the criminal justice system. Recidivism was associated with amphetamine and heroin use, with an additive risk for injectors, and with polysubstance use. Also, recidivism was negatively associated with alcohol, other opioids than heroin/methadone and with hallucinogenic drugs, and positively associated with previous psychiatric in-patient treatment, violent behaviour, and with a shorter index sentence. Associations remained when controlling for type of crime. Even when controlling for type and severity of crime, and for psychiatric problems, risk of criminal relapse was increased by substance use variables, including amphetamine, heroin and polysubstance use, and an additional risk was shown for injection drug users. These findings have implications for the need for substance abuse treatment after release from prison.

2014-11-01

A method to validate the relevance of the Total Diet Study (TDS) approach for different types of substances is described. As a first step, a list of >2800 chemicals classified into eight main groups of relevance for food safety (natural components, environmental contaminants, substances intentionally added to foods, residues, naturally occurring contaminants, process contaminants, contaminants from packaging and food contact materials, other substances) has been established. The appropriateness of the TDS approach for the different substance groups has then been considered with regard to the three essential principles of a TDS: representativeness of the whole diet, pooling of foods and food analyzed as consumed. Four criteria were considered for that purpose (i) the substance has to be present in a significant part of the diet or predominantly present in specific food groups, (ii) a robust analytical method has to be available to determine it in potential contributors to the dietary exposure of the population, and (iii) the dilution impact of pooling and (iv) the impact of everyday food preparation methods on the concentration of the substance are assessed. For most of the substances the TDS approach appeared to be relevant and any precautions to be taken are outlined. Copyright © 2014 Elsevier Ltd. All rights reserved.

Effects of prenatal alcohol and cigarette exposure on offspring substance use in multiplex, alcohol-dependent families.

PubMed

O'Brien, Jessica W; Hill, Shirley Y

2014-12-01

Prenatal exposures to alcohol, cigarettes, and other drugs of abuse are associated with numerous adverse consequences for affected offspring, including increased risk for substance use and abuse. However, maternal substance use during pregnancy appears to occur more often in those with a family history of alcohol dependence. Utilizing a sample that is enriched for familial alcohol dependence and includes controls selected for virtual absence of familial alcohol dependence could provide important information on the relative contribution of familial risk and prenatal exposures to offspring substance use. A sample of multigenerational families specifically ascertained to be at either high or low risk for developing alcohol dependence (AD) provided biological offspring for a longitudinal prospective study. High-risk families were selected based on the presence of 2 alcohol-dependent sisters. Low-risk families were selected on the basis of minimal first and second-degree relatives with AD. High-risk (HR = 99) and Low-risk offspring (LR = 110) were assessed annually during childhood and biennially in young adulthood regarding their alcohol, drug, and cigarette use. At the first childhood visit, mothers were interviewed concerning their prenatal use of substances. High-risk mothers were more likely to use alcohol, cigarettes, and other drugs during pregnancy than low-risk control mothers, and to consume these substances in greater quantities. Across the sample, prenatal exposure to alcohol was associated with increased risk for both offspring cigarette use and substance use disorders (SUD), and prenatal cigarette exposure was associated with increased risk for offspring cigarette use. Controlling for risk status by examining patterns within the HR sample, prenatal cigarette exposure remained a specific predictor of offspring cigarette use, and prenatal alcohol exposure was specifically associated with increased risk for offspring SUD. Women with a family history of SUD are at increased risk for substance use during pregnancy. Both familial loading for alcohol dependence and prenatal exposure to alcohol or cigarettes are important risk factors in the development of offspring substance use. An inadequate assessment of family history may obscure important interactions between familial risk and prenatal exposures on offspring outcomes.

Community partnership to affect substance abuse among Native American adolescents.

PubMed

Lowe, John; Liang, Huigang; Riggs, Cheryl; Henson, Jim; Elder, Tribal

2012-09-01

Substance abuse is one of the nation's primary health concerns. Native American youth experience higher rates of substance abuse than other youth. There is little empirical evidence that exists concerning the use of culturally-based interventions among Native American adolescents. This study used a community-based participatory research approach to develop and evaluate an innovative school-based cultural intervention targeting substance abuse among a Native American adolescent population. A two-condition quasi-experimental study design was used to compare the Cherokee Talking Circle (CTC) culturally-based intervention condition (n = 92) with the Be A Winner Standard Education (SE) condition (n = 87). Data were collected at pre-intervention, immediate post-intervention, and 90-day post-intervention using the Cherokee Self-Reliance Questionnaire, Global Assessment of Individual Needs - Quick, and Written Stories of Stress measures. Significant improvements were found among all measurement outcomes for the CTC culturally-based intervention. The data provide evidence that a Native American adolescent culturally-based intervention was significantly more effective for the reduction of substance abuse and related problems than a noncultural-based intervention. This study suggests that cultural considerations may enhance the degree to which specific interventions address substance abuse problems among Native American adolescents.

A peptidases-resistant glycosylated analogue of substance P-(5-11). Specificity towards substance P receptors.

PubMed

Poujade, C; Lavielle, S; Torrens, Y; Beaujouan, J C; Glowinski, J; Marquet, A

1984-09-01

Glycosylated analogues of the C-terminal heptapeptide of substance P either free or blocked on the N-terminal glutamine were synthesized in order to develop a metabolically stable peptide that would have an increased specificity for one type of receptor. Of the analogue described, (N-alpha-Boc-beta-D-Glc-p (1----5) Gln) -Gln-Phe-Phe-Gly-Leu-Met-NH2 is highly resistant to degradation on exposure to rat hypothalamic slices. This glycosylated peptide is about one third as potent as substance P in eliciting contractions of the guinea-pig ileum and is almost devoided of affinity for the 125I-Bolton Hunter-SP specific binding sites on rat brain synaptosomes.

The relationship between dispositional mindfulness, borderline personality features, and suicidal ideation in a sample of women in residential substance use treatment.

Borderline personality disorder (BPD), which is characterized by unstable moods, behavior, and relationships, is also associated with heightened suicidal ideation. Prior research has demonstrated that BPD and suicidal ideation are prevalent among women in substance use treatment. Efforts to treat substance use in this population are made difficult due to the severity of BPD, and it is possible that mindfulness-based interventions specific to substance use could be an effective approach for this population. However, basic research is needed on the relationship between dispositional mindfulness, BPD, and suicidal ideation among women in treatment for substance use to support their associations, which was the purpose of the present study. Pre-existing medical records were reviewed from a residential substance use treatment center. A total of 81 female patients were included in the current study. Patients completed self-report measures of mindfulness, BPD, suicidal ideation, substance use, and impression management at treatment intake. Findings demonstrated dispositional mindfulness to be negatively associated with BPD features and suicidal ideation. With the exception of self-harm, this negative relationship was found even after controlling for age, substance use, and impression management. Future research should examine whether mindfulness-based interventions are an effective treatment for comorbid substance use and BPD. Copyright © 2016 Elsevier Ireland Ltd. All rights reserved.

A preliminary study of longitudinal neuroadaptation associated with recovery from addiction.

Forster, Sarah E; Finn, Peter R; Brown, Joshua W

2016-11-01

Few studies have explored longitudinal change in event-related brain responses during early recovery from addiction. Moreover, existing findings yield evidence of both increased and decreased signaling within reward and control centers over time. The current study explored reward- and control-related signals in a risky decision-making task and specifically investigated parametric modulations of the BOLD signal, rather than signal magnitude alone. It was hypothesized that risk-related signals during decision-making and outcome evaluation would reflect recovery and that change in specific signals would correspond with improved treatment outcomes. Twenty-one substance dependent individuals were recruited upon enrollment in community-based substance use treatment programs, wherein they received treatment-as-usual. Participants completed functional neuroimaging assessments at baseline and 3-month follow-up while performing the Balloon Analogue Risk Task (BART). Risk- and reward-sensitive signals were identified using parametric modulators. Substance use was tracked throughout the 3-month study interval using the timeline follow-back procedure. Longitudinal contrasts of parametric modulators suggested improved formation of risk-informed outcome expectations at follow-up. Specifically, a greater response to high risk (low-likelihood) positive feedback was identified in caudal anterior cingulate cortex (ACC) and a greater response to low risk (low-likelihood) negative feedback was identified in caudal ACC and inferior frontal gyrus. In addition, attenuation of a ventromedial prefrontal cortex (vmPFC) "reward-seeking" signal (i.e., increasing response with greater reward) during risky decisions at follow-up was associated with less substance use during the study interval. Changes in risk- and reward-related signaling in ACC/vmPFC appear to reflect recovery and may support sobriety. Copyright © 2016 Elsevier Ireland Ltd. All rights reserved.

The study documents the characteristics of Hong Kong residents who used substances in mainland China. Characteristics of such users were compared with those using substances elsewhere. A cross-sectional survey was used. Data analyses were stratified by gender, and multivariate analyses were performed. Respondents, Hong Kong adults aged 18-30 (n = 6,528), were interviewed using a mixed interviewer and computerized mobile phone method, at the Hong Kong-mainland China boundary. Cross-border substance users and other types of substance users had characteristics that were quite different (e.g., education level, perceived harmfulness of substance use in general, having friends who frequently used substances in mainland China). Cross-boundary substance users also found it easier to obtain substances in mainland China than in Hong Kong (males: 60.5%, females: 39.6%) and perceived no chance of being arrested in mainland China because of substance use (men: 28.8%, women: 24.5%). They tended to use substances in discos/rave parties together with friends (men: 77%, women: 81%), and substances were often obtained for free (men: 63.2%, women: 78%). Ecstasy and ketamine were often used (men: 86.5% & 79.4%, women: 81% & 70.2%), and multiple uses of different substances were common (men: 81.3%, women: 68.6%). Lower price, peer influence, and better availability were reasons behind cross-boundary substance use behaviors. Cross-boundary substance users have specific characteristics. Prevention policies should take these characteristics into account. Regional collaborations are highly warranted.

Parental Knowledge is a Contextual Amplifier of Associations of Pubertal Maturation and Substance Use.

PubMed

Marceau, Kristine; Abar, Caitlin C; Jackson, Kristina M

2015-09-01

Earlier pubertal development and less parental knowledge have been linked to more substance use during adolescence. The present study examines interactions between pubertal timing and tempo and parental knowledge (children's disclosure, parental control, and parental solicitation) for adolescent substance initiation. Data are from a northeastern US-based cohort-sequential study examining 1023 youth (52 % female) semiannually for up to 6 assessments (ages 10.5-19 years). The findings supported the hypothesis that lower knowledge is a contextual amplifier of early timing-substance use associations in girls and later timing/slower tempo-substance use associations in boys, though results varied based on source of knowledge. The findings suggest that prevention efforts may have the greatest impact when targeting families of early developing girls, and later developing boys, and that incorporating a focus on specific sources of knowledge depending on the pubertal maturation profile of the adolescent may prove valuable in prevention/intervention efforts.

Targeting children of substance-using parents with the community-based group intervention TRAMPOLINE: A randomised controlled trial - design, evaluation, recruitment issues

PubMed Central

2012-01-01

Background Children of substance-abusing parents are at risk for developing psychosocial development problems. In Germany it is estimated that approx. 2.65 million children are affected by parental substance abuse or dependence. Only ten percent of them receive treatment when parents are treated. To date, no evaluated programme for children from substance-affected families exists in Germany. The study described in this protocol is designed to test the effectiveness of the group programme TRAMPOLINE for children aged 8-12 years with at least one substance-abusing or -dependent caregiver. The intervention is specifically geared to issues and needs of children from substance-affected families. Methods/Design The effectiveness of the manualised nine-session group programme TRAMPOLINE is tested among N = 218 children from substance-affected families in a multicentre randomised controlled trial. Outpatient counselling facilities across the nation from different settings (rural/urban, Northern/Southern/Eastern/Western regions of the country) will deliver the interventions, as they hold the primary access to the target group in Germany. The control condition is a group programme with the same duration that is not addiction-specific. We expect that participants in the intervention condition will show a significant improvement in the use of adaptive coping strategies (in general and within the family) compared to the control condition as a direct result of the intervention. Data is collected shortly before and after as well as six months after the intervention. Discussion In Germany, the study presented here is the first to develop and evaluate a programme for children of substance-abusing parents. Limitations and strengths are discussed with a special focus on recruitment challenges as they appear to be the most potent threat to feasibility in the difficult-to-access target group at hand (Trial registration: ISRCTN81470784).

Commonalities and differences across substance use disorders: phenomenological and epidemiological aspects

PubMed Central

Shmulewitz, Dvora; Greene, Emily R; Hasin, Deborah

2016-01-01

Background Although psychoactive substances vary in many ways, they have important commonalties, particularly in their ability to lead to an addiction syndrome. The field lacks an updated review of the commonalities and differences in the phenomenology of alcohol, cannabis, tobacco, stimulants, opioids, hallucinogens, sedatives/tranquilizers and inhalants and their related substance use disorders (SUD). Methods DSM-IV and DSM-5 SUD diagnostic criteria were reviewed, as was evidence from recent epidemiological and clinical research: psychometric studies (test-retest reliability, latent trait analysis); physiological indicators (tolerance, withdrawal); prevalence and age of onset. Information was incorporated from previous reviews, PubMed and Scopus literature searches, and data from large U.S. national surveys. Results Empirical evidence in the form of test-retest reliability and unidimensionality supports use of the same DSM-IV dependence or DSM-5 SUD diagnostic criteria across substances. For most substances, the criteria sets were generally most informative in general population samples at moderate-to-severe levels of SUD. Across substances, two criteria (tolerance and use in hazardous situations) were identified as functioning differently in population subgroups. Since substances have different pharmacological effects, withdrawal is assessed using substance-specific symptoms, while tolerance is not; issues remain with the assessment of tolerance. Alcohol, tobacco, and cannabis were consistently identified as the substances with earliest onset of use, highest prevalence of lifetime use, and highest prevalence of lifetime disorder. Conclusions Despite differences between psychoactive substances, the generic DSM criteria set appear equally applicable across substances. Additional studies of tolerance and hazardous use will be useful for future nosologies. Alcohol, cannabis, and tobacco are the substances with the greatest public health impact due to the high prevalence and early onset of their use, and the potential all three substances have to lead to addiction.

As the industry moves toward subcutaneous delivery as a preferred route of drug administration, high drug substance concentrations are becoming the norm for monoclonal antibodies. At such high concentrations, the drug substance may display a more intense color than at the historically lower concentrations. The effect of process conditions and/or changes on color is more readily observed in the higher color, high concentration formulations. Since color is a product quality attribute that needs to be controlled, it is useful to study the impact of process conditions and/or modifications on color. This manuscript summarizes cell culture experiments and reports on findings regarding the effect of various media components that contribute to drug substance color for a specific monoclonal antibody. In this work, lower drug substance color was achieved via optimization of the cell culture medium. Specifically, lowering the concentrations of B-vitamins in the cell culture medium has the effect of reducing color intensity by as much as 25%. In addition, decreasing concentration of iron was also directly correlated color intensity decrease of as much as 37%. It was also shown that the color of the drug substance directly correlates with increased acidic variants, especially when increased iron levels cause increased color. Potential mechanisms that could lead to antibody coloration are briefly discussed. © 2013 American Institute of Chemical Engineers.

The interacting effect of depressive symptoms, gender, and distress tolerance on substance use problems among residential treatment-seeking substance users.

PubMed

Ali, Bina; Seitz-Brown, C J; Daughters, Stacey B

2015-03-01

Depression is associated with substance use problems; however, the specific individual characteristics influencing this association are not well identified. Empirical evidence and theory suggest that gender and distress tolerance-defined behaviorally as an individual's ability to persist in goal-directed behavior while experiencing negative affective states-are important underlying factors in this relationship. Hence, the purpose of the current study was to examine whether gender and distress tolerance moderate the relationship between depressive symptoms and substance use problems. Participants included 189 substance users recruited from a residential substance abuse treatment center. The Short Inventory of Problems-Alcohol and Drugs scale was used to measure self-reported substance use problems. The Beck Depression Inventory was used to assess self-reported depressive symptoms. Gender was self-reported, and distress tolerance was behaviorally indexed by the Computerized Paced Auditory Serial Addition Task. Hierarchical linear regression analysis indicated a significant three-way interaction of depressive symptoms, gender, and distress tolerance on substance use problems, adjusting for relevant demographic variables, anxiety symptoms, impulsivity, as well as DSM-IV psychiatric disorders. Probing of this three-way interaction demonstrated a significant positive association between depressive symptoms and substance use problems among females with low distress tolerance. Findings indicate that female treatment-seeking substance users with high levels of depressive symptoms exhibit greater substance use problems if they also evidence low distress tolerance. Study implications are discussed, including the development of prevention and intervention programs that target distress tolerance skills. Copyright © 2015 Elsevier Ireland Ltd. All rights reserved.

Substance and Artifact in the Higher-Order Factors of the Big Five

J. M. Digman (1997) proposed that the Big Five personality traits showed a higher-order structure with 2 factors he labeled α and β. These factors have been alternatively interpreted as heritable components of personality or as artifacts of evaluative bias. Using structural equation modeling, the authors reanalyzed data from a cross-national twin study and from American cross-observer studies and analyzed new multimethod data from a German twin study. In all analyses, artifact models outperformed substance models by root-mean-square error of approximation criteria, but models combining both artifact and substance were slightly better. These findings suggest that the search for the biological basis of personality traits may be more profitably focused on the 5 factors themselves and their specific facets, especially in monomethod studies.

The National Institute of Drug Abuse's National Drug Abuse Treatment Clinical Trials Network (CTN) was established to foster translation of research into practice in substance abuse treatment settings. The CTN provides a unique opportunity to examine in multi-site, translational clinical trials, the outcomes of treatment interventions targeting vulnerable subgroups of women; the comparative effectiveness of gender-specific protocols to reduce risk behaviors; and gender differences in clinical outcomes. To review gender-related findings from published CTN clinical trials and related studies from January 2000 to March 2010. CTN studies were selected for review if they focused on treatment outcomes or services for special populations of women with substance use disorders (SUDs) including those with trauma histories, pregnancy, co-occurring eating and other psychiatric disorders, and HIV risk behaviors; or implemented gender-specific protocols. The CTN has randomized 11,500 participants (41% women) across 200 clinics in 24 randomized controlled trials in community settings, of which 4 have been gender-specific. This article summarizes gender-related findings from CTN clinical trials and related studies, focusing on trauma histories, pregnancy, co-occurring eating and other psychiatric disorders, and HIV risk behaviors. These published studies have expanded the evidence base regarding interventions for vulnerable groups of women with SUDs as well as gender-specific interventions to reduce HIV risk behaviors in substance-using men and women. The results also underscore the complexity of accounting for gender in the design of clinical trials and analysis of results. To fully understand the relevance of gender-specific moderators and mediators of outcome, it is essential that future translational studies adopt more sophisticated approaches to understanding and measuring gender-relevant factors and plan sample sizes that are adequate to support more nuanced analytic methods.

Social Influences on College Student Use of Tobacco Products, Alcohol, and Marijuana.

This study investigated associations between the use of alternative tobacco products (e.g., cigarettes, little cigars/cigarillos, hookah, e-cigarettes), alcohol, and marijuana among college students and use by their parents, siblings, and friends. A large literature exists for social influences on adolescent substance use, but few studies have focused on college samples. 3,418 college students from seven universities in the state of Georgia participated in this study. Web-based surveys were completed by students (45-60 minutes) during the fall semester, 2014. Findings largely indicated specificity of associations between college student use and use by social influences for similar tobacco products and other substances. For each tobacco product or substance, the highest associations were for friends' use. Structural equation analyses further supported the specificity of associations and highlighted the relative strength of friends' use on student use. Similar to findings with adolescents, the use of alternative tobacco products, alcohol, and marijuana by parents, siblings, and friends is associated with higher levels of use among college students, and friends' use was the most potent correlate for this phase of the lifespan.

2011-08-01

Many individuals expect that alcohol and drug consumption will enhance creativity. The present studies tested whether substance related primes would influence creative performance for individuals who possessed creativity-related substance expectancies. Participants (n = 566) were briefly exposed to stimuli related to psychoactive substances (alcohol, for Study 1, Sample 1, and Study 2; and marijuana, for Study 1, Sample 2) or neutral stimuli. Participants in Study 1 then completed a creative problem-solving task, while participants in Study 2 completed a divergent thinking task or a task unrelated to creative problem solving. The results of Study 1 revealed that exposure to the experimental stimuli enhanced performance on the creative problem-solving task for those who expected the corresponding substance would trigger creative functioning. In a conceptual replication, Study 2 showed that participants exposed to alcohol cues performed better on a divergent thinking task if they expected alcohol to enhance creativity. It is important to note that this same interaction did not influence performance on measures unrelated to creative problem solving, suggesting that the activation of creativity-related expectancies influenced creative performance, specifically. These findings highlight the importance of assessing expectancies when examining pharmacological effects of alcohol and marijuana. Future directions and implications for substance-related interventions are discussed. (c) 2011 APA, all rights reserved.

2014-01-01

Adults with substance use disorders (SUDs) report a high prevalence of childhood abuse. Research in the general population suggests specific types of abuse lead to particular negative outcomes; it is not known whether this pattern holds for adults with SUDs. We hypothesized that specific types of abuse would be associated with particular behavioral and emotional outcomes among substance users. That is, childhood sexual abuse would be associated with risky sex behaviors, childhood physical abuse with aggression, and childhood emotional abuse with emotion dysregulation. 280 inpatients (M age = 43.3; 69.7% male; 88.4% African American) in substance use treatment completed the Childhood Trauma Questionnaire (CTQ), HIV Risk-Taking Behavior Scale, Addiction Severity Index, Difficulties with Emotion Regulation Scale (DERS), Distress Tolerance Scale (DTS), and Affect Intensity and Dimensions of Affiliation Motivation (AIM). Consistent with our hypotheses, the CTQ Sexual Abuse subscale uniquely predicted exchanging sex for cocaine and heroin, number of arrests for prostitution, engaging in unprotected sex with a casual partner during the prior year, and experiencing low sexual arousal when sober. The Physical Abuse subscale uniquely predicted number of arrests for assault and weapons offenses. The Emotional Abuse subscale uniquely predicted the DERS total score, AIM score, and DTS score. Among substance users, different types of abuse are uniquely associated with specific negative effects. Assessment of specific abuse types among substances users may be informative in treatment planning and relapse prevention. PMID:24521524

There are high levels of comorbidity between schizophrenia and substance use disorder, but little is known about the genetic etiology of this comorbidity. We tested the hypothesis that shared genetic liability contributes to the high rates of comorbidity between schizophrenia and substance use disorder. To do this, polygenic risk scores for schizophrenia derived from a large meta-analysis by the Psychiatric Genomics Consortium were computed in three substance use disorder datasets: the Collaborative Genetic Study of Nicotine Dependence (ascertained for tobacco use disorder; n = 918 cases; 988 control subjects), the Collaborative Study on the Genetics of Alcoholism (ascertained for alcohol use disorder; n = 643 cases; 384 control subjects), and the Family Study of Cocaine Dependence (ascertained for cocaine use disorder; n = 210 cases; 317 control subjects). Phenotypes were harmonized across the three datasets and standardized analyses were performed. Genome-wide genotypes were imputed to the 1000 Genomes reference panel. In each individual dataset and in the mega-analysis, strong associations were observed between any substance use disorder diagnosis and the polygenic risk score for schizophrenia (mega-analysis pseudo-R 2 range 0.8-3.7%; minimum p = 4 × 10 -23 ). These results suggest that comorbidity between schizophrenia and substance use disorder is partially attributable to shared polygenic liability. This shared liability is most consistent with a general risk for substance use disorder rather than specific risks for individual substance use disorders and adds to increasing evidence of a blurred boundary between schizophrenia and substance use disorder.

Comorbidity of substance use with depression and other mental disorders: from Diagnostic and Statistical Manual of Mental Disorders, fourth edition (DSM-IV) to DSM-V.

Nunes, Edward V; Rounsaville, Bruce J

2006-09-01

To arrive at recommendations for addressing co-occurring psychiatric and substance use disorders in the development of the Diagnostic and Statistical Manual of Mental Disorders fifth edition (DSM-V) criteria. Synthesis of findings of other papers from a consensus conference and from the literature on diagnosis and treatment of co-occurring psychiatric and substance use disorders. Most of the relevant studies examine co-occurring depression. The diagnosis and treatment of psychiatric syndromes that co-occur with substance use disorders has been a source of controversy, fueled in part by limitations of pre-DSM-IV nosologies. The DSM-IV scheme of classifying co-occurring disorders as primary (also referred to as independent) or substance-induced has promise in terms of good predictive validity, although pertinent longitudinal and treatment studies are limited. The substance-induced category answers the need of clinicians for a way to categorize patients with clinically significant psychiatric symptoms that occur in the setting of ongoing substance use. DSM-V should retain the primary (independent) and substance-induced categories. In DSM-IV these categories are broadly defined and leave much to clinical judgement. Existing data sets should be brought to bear to refine the criteria, making them more detailed with clearer anchor points and more specificity around particular substances and psychiatric syndromes. More longitudinal studies and clinical trials are also needed. Looking beyond DSM-V, co-occurring psychiatric syndromes are likely to be important in the quest for a nosology founded on pathophysiology.

Substance use and mental health disorders are linked to different forms of intimate partner violence victimisation.

Substance and mental health disorders convey significant health burdens and impair interpersonal relationships. We tested associations between comorbid substance and mental health disorders and different forms of intimate partner violence (IPV) experienced by young adults. Mothers (n = 6703) were recruited during pregnancy to the longitudinal Mater-University of Queensland Study of Pregnancy. Mother/offspring dyads were followed up from birth to 21 years. Offspring with complete psychiatric data at 21 years who reported having had an intimate partnership were included (n = 1781). Participants' experiences of psychological, physical and severe combined IPV were assessed at 21 years using a summarised form of the Composite Abuse Scale. We used the Composite International Diagnostic Interview to obtain lifetime diagnoses of mental health and substance disorders. Multivariable logistic regression models of each IPV form were adjusted for individual, family and neighbourhood factors during adolescence, and for other forms of IPV. We have shown specific links between different forms of IPV experienced and individual substance and mental health disorders. Mental health disorders were related to all three forms of IPV, while alcohol disorders were linked to psychological IPV (ORAUD = 1.86; 1.21-2.86) and illicit substance disorders to physical IPV (ORSUD = 2.07; 1.25-3.43). The co-occurrence of related disorders was strongly linked to psychological and physical IPV. Intimate partner violence was experienced by both men and women. Substance and mental health disorders were associated with specific forms of IPV victimisation, suggesting that screening IPV clients and mental health/substance disorder patients for the converse problems may be important for intervention planning.

Estimates suggest 30% of adults report the highest levels of loneliness. Though men are more likely than women to use illicit substances and engage in heavy drinking, the prevalence of substance use in women is growing and their escalation towards dependence occurs more rapidly. Loneliness and substance use have greater relevance within the HIV+ population, with higher rates of substance misuse than the general population. However, the association between loneliness and substance use within HIV+ individuals remains understudied. The purpose of the present study was to test the hypothesis that there would be an association between loneliness and substance moderated by gender in HIV+ older adults. A cross sectional study was conducted between October 2013 and January 2014. Study participants included 96 HIV-positive Black/African American men and women recruited through the University of Florida Center for HIV/AIDS Research, Education and Service (UF CARES) in Jacksonville, Florida. Participants completed an interviewer-administered assessment examining mental and behavioral health. Pearson correlations examined associations between loneliness and substance use. Binary logistic regression analyses stratified by gender examined the association between loneliness and substance use while controlling for covariates. Among women, loneliness was associated with illicit drug use, AOR=3.37, 95% CI: 1.23 – 9.21, p =. 018 and heavy drinking, AOR=2.47, 95% CI: 1.07 – 5.71, p =. 033. No significant associations were found between loneliness and illicit drug use, and heavy drinking in men. Substance use among women in this population may be linked to loneliness. Interventions should be gender specific. Further research into this association is necessary as it will likely have important clinical implications for this population. PMID:26654243

Unique aspects of impulsive traits in substance use and overeating: specific contributions of common assessments of impulsivity.

Abstract Background: Impulsivity is a complex trait often studied in substance abuse and overeating disorders, but the exact nature of impulsivity traits and their contribution to these disorders are still debated. Thus, understanding how to measure impulsivity is essential for comprehending addictive behaviors. Identify unique impulsivity traits specific to substance use and overeating. Impulsive Sensation Seeking (ImpSS) and Barratt's Impulsivity scales (BIS) Scales were analyzed with a non-parametric factor analytic technique (discriminant correspondence analysis) to identify group-specific traits on 297 individuals from five groups: Marijuana (n = 88), Nicotine (n = 82), Overeaters (n = 27), Marijuauna + Nicotine (n = 63), and CONTROLs (n = 37). A significant overall factor structure revealed three components of impulsivity that explained respectively 50.19% (pperm < 0.0005), 24.18% (pperm < 0.0005), and 15.98% (pperm < 0.0005) of the variance. All groups were significantly different from one another. When analyzed together, the BIS and ImpSS produce a multi-factorial structure that identified the impulsivity traits specific to these groups. The group specific traits are (1) CONTROL: low impulse, avoids thrill-seeking behaviors; (2) Marijuana: seeks mild sensation, is focused and attentive; (3) Marijuana + Nicotine: pursues thrill-seeking, lacks focus and attention; (4) Nicotine: lacks focus and planning; (5) Overeating: lacks focus, but plans (short and long term). Our results reveal impulsivity traits specific to each group. This may provide better criteria to define spectrums and trajectories - instead of categories - of symptoms for substance use and eating disorders. Defining symptomatic spectrums could be an important step forward in diagnostic strategies.

Schwinn, Traci M; Schinke, Steven P; Hopkins, Jessica; Thom, Bridgette

2016-01-01

Despite overall reductions in teenage substance use, adolescent girls' rates of substance use remain unacceptably high. This article examines whether girls' substance use is associated with general risk and protective factors (goal setting, problem solving, refusal skills, peer use, and self-efficacy) and gender-specific risk and protective factors (communication style, coping skills, self-esteem, body image, perceived stress, anxiety, and depression). Cross-sectional data were collected in 2013 via online surveys from a nationwide sample of adolescent girls (N = 788), aged 13 and 14 years, who were recruited through Facebook. In multivariate analyses, controlling for correlates of adolescent substance use, 11 of the 13 general and gender-specific risk and protective factors were consistently associated with past-month alcohol, cigarette, and other drug use in the expected direction; past-month marijuana use was associated with 8 of the 13 factors. Refusal skills, peer use, coping, and depressive mood were most consistently and strongly associated with substance use. Substance abuse prevention programs targeting adolescent girls should focus on such general risk and protective factors as problem solving, refusal skills, peer influences, and self-efficacy, as well as such gender-specific risk and protective factors as communication style, coping, self-esteem, body image, perceived stress, and mood management.

PTSD Symptom Severities, Interpersonal Traumas, and Benzodiazepines Are Associated with Substance-Related Problems in Trauma Patients

PubMed Central

Guina, Jeffrey; Nahhas, Ramzi W.; Goldberg, Adam J.; Farnsworth, Seth

2016-01-01

Background: Trauma is commonly associated with substance-related problems, yet associations between specific substances and specific posttraumatic stress disorder symptoms (PTSSs) are understudied. We hypothesized that substance-related problems are associated with PTSS severities, interpersonal traumas, and benzodiazepine prescriptions. Methods: Using a cross-sectional survey methodology in a consecutive sample of adult outpatients with trauma histories (n = 472), we used logistic regression to examine substance-related problems in general (primary, confirmatory analysis), as well as alcohol, tobacco, and illicit drug problems specifically (secondary, exploratory analyses) in relation to demographics, trauma type, PTSSs, and benzodiazepine prescriptions. Results: After adjusting for multiple testing, several factors were significantly associated with substance-related problems, particularly benzodiazepines (AOR = 2.78; 1.99 for alcohol, 2.42 for tobacco, 8.02 for illicit drugs), DSM-5 PTSD diagnosis (AOR = 1.92; 2.38 for alcohol, 2.00 for tobacco, 2.14 for illicit drugs), most PTSSs (especially negative beliefs, recklessness, and avoidance), and interpersonal traumas (e.g., assaults and child abuse). Conclusion: In this clinical sample, there were consistent and strong associations between several trauma-related variables and substance-related problems, consistent with our hypotheses. We discuss possible explanations and implications of these findings, which we hope will stimulate further research, and improve screening and treatment. PMID:27517964

This study evaluated the effectiveness of a brief intervention (BI) for illicit drugs (cannabis, cocaine, amphetamine-type stimulants and opioids) linked to the World Health Organization (WHO) Alcohol, Smoking and Substance Involvement Screening Test (ASSIST). The ASSIST screens for problem or risky use of 10 psychoactive substances, producing a score for each substance that falls into either a low-, moderate- or high-risk category. Prospective, randomized controlled trial in which participants were either assigned to a 3-month waiting-list control condition or received brief motivational counselling lasting an average of 13.8 minutes for the drug receiving the highest ASSIST score. Primary health-care settings in four countries: Australia, Brazil, India and the United States. A total of 731 males and females scoring within the moderate-risk range of the ASSIST for cannabis, cocaine, amphetamine-type stimulants or opioids. ASSIST-specific substance involvement scores for cannabis, stimulants or opioids and ASSIST total illicit substance involvement score at baseline and 3 months post-randomization. Omnibus analyses indicated that those receiving the BI had significantly reduced scores for all measures, compared with control participants. Country-specific analyses showed that, with the exception of the site in the United States, BI participants had significantly lower ASSIST total illicit substance involvement scores at follow-up compared with the control participants. The sites in India and Brazil demonstrated a very strong brief intervention effect for cannabis scores (P < 0.005 for both sites), as did the sites in Australia (P < 0.005) and Brazil (P < 0.01) for stimulant scores and the Indian site for opioid scores (P < 0.01). The Alcohol, Smoking and Substance Involvement Screening Test-linked brief intervention aimed at reducing illicit substance use and related risks is effective, at least in the short term, and the effect generalizes across countries. © 2011 The Authors, Addiction © 2011 Society for the Study of Addiction.

2014-12-01

To examine the genetic overlap between borderline personality features (BPF) and substance use disorders (SUDs) and the extent to which variation in personality traits contributes to this covariance. Genetic structural equation modelling was used to partition the variance in and covariance between personality traits, BPF and SUDs into additive genetic, shared and individual-specific environmental factors. All participants were registered with the Australian Twin Registry. A total of 3127 Australian adult twins participated in the study. Diagnoses of DSM-IV alcohol and cannabis abuse/dependence (AAD; CAD) and nicotine dependence (ND) were derived via computer-assisted telephone interview. BPF and five-factor model personality traits were derived via self-report questionnaires. Personality traits, BPF and substance use disorders were partially influenced by genetic factors with heritability estimates ranging from 0.38 (neuroticism; 95% confidence interval: 0.30-0.45) to 0.78 (CAD; 95% confidence interval: 0.67-0.86). Genetic and individual-specific environmental correlations between BPF and SUDs ranged from 0.33 to 0.56 (95% CI = 0.19-0.74) and 0.19-0.32 (95% CI = 0.06-0.43), respectively. Overall, there was substantial support for genetic influences that were specific to AAD, ND and CAD (30.76-68.60%). Finally, genetic variation in personality traits was responsible for 11.46% (extraversion for CAD) to 59.30% (neuroticism for AAD) of the correlation between BPF and SUDs. Both genetic and individual-specific environmental factors contribute to comorbidity between borderline personality features and substance use disorders. A substantial proportion of this comorbidity can be attributed to variation in normal personality traits, particularly neuroticism. © 2014 Society for the Study of Addiction.

The aim of most population-based studies of media is to relate a specific exposure to an outcome of interest. A research program has been developed that evaluates exposure to different components of movies in an attempt of assess the association of such exposure with the adoption of substance use during adolescence. To assess exposure to movie substance use, one must measure both viewing time and content. In developing the exposure measure, the study team was interested in circumventing a common problem in exposure measurement, where measures often conflate exposure to media with attention to media. Our aim in this paper is to present a validated measure of exposure to entertainment media, the Beach method, which combines recognition of a movie title with content analysis of the movie for substance use, to generate population based measures of exposure to substance use in this form of entertainment.

Substance addiction in young adults is particularly problematic. Yet, much remain at stake in understanding the specifics of this population's access to services. The objective of this study is to explore young adults' initiation of substance misuse treatment. Our study sample was composed of 35 individuals aged 18 to 30 with problematic psychoactive substance use who have been identified in criminal courts, hospital emergency departments, and Health and Social Services Centers in Québec (Canada). A thematic analysis was performed on the 62 semi-structured interviews conducted with participants. Three components emerged. First, personal elements-expectations, individual motivations, perceptions of use, and capacity to control it-influence initiation of substance misuse treatment. Second, family and peers have noticeable influences. Finally, system characteristics and prior care experiences also shape the process. Consideration should be given to tailor interventions that can reach young adults and encourage them to initiate appropriate care.

Personality psychopathology, drug use and psychological symptoms in adolescents with substance use disorders and community controls

Forns, Maria; Goti, Javier; Castro-Fornieles, Josefina

2015-01-01

Substance use is a risk behavior that tends to increase during adolescence, a time when part of the personality is still in development. Traditionally, personality psychopathology has been measured in terms of categories, although dimensional models have demonstrated better consistency. This study aimed to analyze differences in personality profiles between adolescents with substance use disorders (SUD n = 74) and matched community controls (MCC n = 74) using the Personality Psychopathology Five (PSY-5) dimensional model. Additionally, we compared age at first drug use, level of drug use and internalizing and externalizing symptoms between the groups. In this study, the PSY-5 model has proved to be useful for differentiating specific personality disturbances in adolescents with SUD and community adolescents. The Disconstraint scale was particularly useful for discriminating adolescents with substance use problems and the Delinquent Attitudes facet offered the best differentiation. PMID:26082873

Family Structure and Adolescent Substance Use: An International Perspective.

PubMed

Hoffmann, John P

2017-11-10

Numerous studies indicate that family structure is a key correlate of adolescent substance use. Yet there are some important limitations to this research. Studies have been conducted mainly in the United States, with relatively few studies that have compared family structure and youth substance use across nations. There is also a lack of recognition of the complexity of family types prevalent in contemporary global society. Moreover, there remains a need to consider personal, interpersonal, and macro-level characteristics that may help account for the association between family structure and youth substance use. This study uses data from 37 countries to examine several models that purport to explain the association between family structure and substance use. The data are from the 2005-2006 WHO-sponsored Health Behaviour in School-Aged Children (HBSC) (n = 193,202). Multilevel models, including linear, probit, and structural equation models (SEMs), were used to test several hypotheses. The results suggest that time spent with friends largely accounted for the association between specific types of family structures and frequency of alcohol use and getting drunk, but that cannabis use was negatively associated with living with both biological parents irrespective of other factors.

Given that women increasingly report using drugs to lose weight, substance abuse treatment programs must include body image, weight, eating pathology, and health knowledge as core intervention targets. This study tested the efficacy of a supplemental health and body image curriculum designed for women in substance abuse treatment who report weight concerns called Healthy Steps to Freedom (HSF). Data from 124 adult women recruited from substance abuse treatment facilities in southern Nevada completed measures of drug use, body dissatisfaction, eating pathology, thin-ideal internalization, and health knowledge/behaviors before and after participation in the 12-week HSF program. Results revealed that thin-ideal internalization, body dissatisfaction, and eating disorder symptoms significantly decreased after HSF program participation, whereas health-related behaviors (e.g., increased healthy food consumption) and knowledge (e.g., understanding of basic nutrition, exercise) increased. These results suggest that the inclusion of the HSF program in substance abuse treatment improves weight-related issues in substance-abusing women. Copyright © 2012 Elsevier Inc.

Relatively little attention has been afforded to protective factors for community-level risks among non-urban populations. This study examined the extent to which traditional cultural attitudes and behaviors of 137 African American adolescents (ages 12-17) from a rural community moderated the relationship between perceived community disorganization and substance use behaviors. Results from hierarchical linear regression revealed that traditional cultural attitudes and behaviors were differentially related to community disorganization and adolescent substance use. In terms of protective influences, religious beliefs and practices and traditional family practices moderated the effect of community disorganization on substance use. Specifically, religious beliefs and practices demonstrated a protective-stabilizing effect as community disorganization increased; traditional family practices demonstrated a protective but reactive effect. Attitudes of cultural mistrust increased youth's susceptibility to substance use as community disorganization worsened--vulnerable and reactive. The findings underscore the importance of examining the link between cultural and contextual factors in an attempt to understand the etiology of substance use among rural African American adolescents.

Substance abuse and criminality share a complex relationship. The rates of substance use among the prisoners, and that of criminal acts among substance users in community setting are high. Data from South Asian countries, including from India are inadequate. This study aimed to assess the pattern of criminal acts among opioid-dependent subjects and their substance use pattern in the month before, during and after imprisonment. Using a cross-sectional study design and purposive sampling, opioid-dependent subjects (n=101) attending two community drug treatment clinics who have had any contact with the law were assessed using a specifically-designed tool to record criminal acts and substance use before, during and after last imprisonment. Most subjects (93%) had committed illegal acts in their lifetime. Physical assault was the most common illegal act, while 23% reported selling drugs and 9% reported committing serious crimes. About 95% were arrested and 92% had spent time in police lockups. About 29% were arrested for drugs possession or drug use, and 3% of injecting drug users arrested for carrying injection equipment. About 85% had been imprisoned at least once, of whom 88% used psychoactive substances in the 1-month period before their last imprisonment. Opioids were the most common substances used daily (68%), followed by cannabis (34%) and alcohol (22%). Ninety-seven percent reported the availability of substances in prisons, and 65% also used substances during their last imprisonment. Cannabis (35%) was the most common substances used in prison followed by opioids (19%). Seventy-six percent used substances soon after prison release, and 13% of opioid users experienced opioid overdose soon after prison release. Use of cannabis, injecting drugs, and opioid use before imprisonment were predictors of substance use in prison. Opioid-dependent people have various contacts with the law, including imprisonment. Many users are dependent on substances during prison-entry, which is an important reason for their continued substance use in prisons. There is a need to provide substance abuse treatment across all stages of criminal justice system. Copyright © 2015 Elsevier Inc. All rights reserved.

To examine the effects of incorporating tribal specific cultural beliefs into a tailored substance abuse prevention intervention for at risk rural Oklahoma Native American Indian (NAI) Plains adolescents. The 10 hour Native American Talking Circle Intervention, a school-based, group substance abuse prevention program, was implemented over a 8.5 week period and evaluated using a one group, pretest-posttest design. Measurements were from the Native Self-Reliance Questionnaire and the Substance Problems Scale from Global Appraisal of Individual Needs-Quick (GAIN-Q). One-tailed, paired sample t-tests demonstrated significant increase in self-reliance, from 86.227 to 92.204 (t (43) = -2.580, p = .007) and a decrease in substance abuse/use, from 2.265 to 1.265 (t (33) = 1.844, p = .007). The Native Talking Circle Intervention based on tribal-specific values and beliefs was shown to be effective with substance abuse/use at-risk NAI Plains tribal adolescents.

The current study aimed to inform future interventions for heavy alcohol use and problems among college students by examining the utility of normative perceptions and coping strategies in predicting alcohol use among student service members/Veterans (SSM/Vs). SSM/Vs and civilian students (N=319) at a large university in the Southern Plains completed self-report measures of demographics, alcohol use and related behaviors, and coping strategies. Both SSM/Vs and civilian students significantly overestimated the typical weekly drinking quantities and frequencies of same-sex students on campus. Among SSM/Vs, normative perceptions of typical student (not military-specific) drinking and substance-related coping strategies significantly predicted drinks consumed per week, while substance-related coping predicted alcohol-related consequences. Despite the theoretical importance of similarity to normative referents, military-specific norms did not significantly improve the prediction of SSM/Vs' personal drinking behavior. Moreover, neither typical student nor military-specific norms predicted alcohol-related consequences among SSM/Vs after accounting for substance-related coping strategies. Future research may examine the efficacy of descriptive normative feedback and the importance of military-specific norms in alcohol interventions for SSM/Vs. Copyright © 2016 Elsevier Ltd.

Risk factors for criminal recidivism – a prospective follow-up study in prisoners with substance abuse

PubMed Central

2012-01-01

Background Substance use in general has been shown to predict criminal recidivism. The present study aimed to examine potential predictors of criminal recidivism, including substance-specific substance use patterns, in prisoners with substance use. Methods A cohort of prisoners with substance use problems (N = 4,152) were assessed with the Addiction Severity Index (ASI) in the Swedish criminal justice system. Clients were followed for an average of 2.7 years. Criminal recidivism was defined as any return to the criminal justice system. Results During follow-up, 69 percent (n = 2,862) returned to the criminal justice system. Recidivism was associated with amphetamine and heroin use, with an additive risk for injectors, and with polysubstance use. Also, recidivism was negatively associated with alcohol, other opioids than heroin/methadone and with hallucinogenic drugs, and positively associated with previous psychiatric in-patient treatment, violent behaviour, and with a shorter index sentence. Associations remained when controlling for type of crime. Conclusions Even when controlling for type and severity of crime, and for psychiatric problems, risk of criminal relapse was increased by substance use variables, including amphetamine, heroin and polysubstance use, and an additional risk was shown for injection drug users. These findings have implications for the need for substance abuse treatment after release from prison. PMID:22894706

Self-medication hypothesis of substance use: testing Khantzian's updated theory.

PubMed

Hall, Danny H; Queener, John E

2007-06-01

Substance use research has been a salient focus for mental health professionals in recent years. Several organizations, including the American Psychological Association, have been pressing for more substance use research, particularly clinically relevant, theory-based investigations. However, there are few theories of substance use, and even fewer with scientific support. One theory is the Self Medication Hypothesis by Khantzian (1977, 1974), a theory with 30 years of research. However, recent modifications in Khantzian's theory (1999) have not been properly tested. Specifically, two areas require further investigation: Khantzian's belief that more negative affect should be related directly to more substance use, and expanding the number of affective states examined, including alexithymia, to better operationalize Khantzian's belief that several painful and ambiguous forms of affect may be implicated in the self-medicating process. The current study assessed anxiety, depression, hostility and alexithymia levels in 70 methadone maintenance treatment patients. Results indicated that affective measures did not have the expected relationship with reported substance use. The authors advocate for the exploration of multiple factors, not merely emotional regulation, in the variability of substance use.

Toxic substances have been suspected of being one of the causes of Great Lakes lake trout reproductive failure. Because toxic substances are present in the Great Lakes basin, managers should be aware of the role of contaminants in preventing lake trout rehabilitation. This paper summarizes studies which have sought to establish a relation between toxic substances and lake trout mortality or morbidity, and offers recommendations for future research and management. The review suggests that exposure to toxic substances has the possibility of affecting the species' rehabilitation. A variety of toxic substances, specifically organochlorine compounds, concentrated in lake trout eggs, fry, and the environment, have affected the hatching success of lake trout in the laboratory, but the strength of the relation between toxic substances and lake trout mortality and morbidity in the field remains unclear. In order to clarify this relation, more information is needed on lake trout physiology, biochemistry, behavior, and genetics. An interdisciplinary workshop should be convened to evaluate existing evidence by epidemiological methods, to set priorities for further research, and to develop management strategies.

Smoking is highly prevalent among individuals with drug and alcohol disorders. Concurrent tobacco dependence treatment during substance use disorder (SUD) treatment is supported, yet the association between SUD treatment outcomes and smoking status has been understudied in minorities, including Latinos. Participants were 322 Spanish-speaking Latinos enrolled in a SUD treatment study in 5 U.S. cities. Logistic regression examined associations between baseline smoking status and treatment outcomes for nontobacco substance use at follow-up. Covariates included age, gender, level of education, marital status, treatment group, and mandated treatment status. Results indicated smokers had a reduced likelihood of abstinence for all nontobacco substances (p = .001) and their primary drug of use (p = .007). Findings contribute to the growing literature indicating a possible beneficial effect of smoking cessation services on SUD treatment, specifically among Latinos. Further research is needed to identify ideal smoking cessation treatments for Latinos. © 2016 Wiley Periodicals, Inc.

2011-01-01

The two most common comorbid conditions with HIV are substance use disorders and depression, and individuals with comorbid HIV, depression, and substance dependence face a more chronic and treatment-resistant course. As an example of how to adapt evidence-based approaches to a complex comorbid population, the current case study examined the integration of a combined depression and HIV medication adherence treatment. The resulting intervention, ACT HEALTHY, combines a brief behavioral activation approach specifically developed to treat depression in individuals receiving residential substance abuse treatment (LETS ACT; Daughters et al., 2008) with a brief cognitive-behavioral approach to improving HIV medication adherence (Life-Steps; Safren et al., 1999; Safren et al., 2009). The current case series demonstrates the use of ACT HEALTHY among 3 depressed HIV-positive, low-income African Americans entering residential substance abuse treatment. PMID:21709737

The doctrine of signatures in the medieval and Ottoman Levant.

This study traces the use of the Doctrine of Signatures among medieval and Ottoman physicians and its subsequent appearance in the pharmacological literature of the Levant. Close examination of the historical sources of the Levant seems to support the claim that although this theory did not originate in the region, it was certainly practised there. These sources have revealed 23 substances with medicinal uses based on the Doctrine, bearing witness to the extent of its influence at the time. The main categories of the Doctrine uncovered were: similarity between the substance used and the human organ; resemblance in shape or behaviour to a specific animal; correlation between the colour of a substance and the colour of the symptoms; similarities between the substance and the patient's symptoms and the use of a substance that might produce symptoms of a particular disease in a healthy person to remedy those same symptoms in one who is sick.

The prevalence of new psychoactive substances (NPSs) in forensic casework has increased prominently in recent years. This has given rise to significant legal and analytical challenges in the identification of these substances. The requirement for validated, robust and rapid testing methodologies for these compounds is obvious. This study details the analysis of 13 synthesised diphenidine derivatives encountered in casework using presumptive testing, thin layer chromatography and gas chromatography-mass spectrometry (GC-MS). Specifically, the validated GC-MS method provides, for the first time, both a general screening method and quantification of the active components for seized solid samples, both in their pure form and in the presence of common adulterants.

1989-07-01

In vitro studies have demonstrated that glia can express functional receptors for a variety of neurotransmitters. To determine whether similar neurotransmitter receptors are also expressed by glia in vivo, the authors examined the glial scar in the transected optic nerve of the albino rabbit by quantitative receptor autoradiography. Receptor binding sites for radiolabeled calcitonin gene-related peptide, cholecystokinin, galanin, glutamate, somatostatin, substance P, and vasoactive intestinal peptide were examined. Specific receptor binding sites for each of these neurotransmitters were identified in the rabbit forebrain but were not detected in the normal optic nerve or tract. In the transected optic nerve andmore » tract, only receptor binding sites for substance P were expressed at detectable levels. The density of substance P receptor binding sites observed in this glial scar is among the highest observed in the rabbit forebrain. Ligand displacement and saturation experiments indicate that the substance P receptor binding site expressed by the glial scar has pharmacological characteristics similar to those of substance P receptors in the rabbit striatum, rat brain, and rat and canine gut. The present study demonstrates that glial cells in vivo express high concentrations of substance P receptor binding sites after transection of retinal ganglion cell axons. Because substance P has been shown to regulate inflammatory and immune responses in peripheral tissues, substance P may also, by analogy, be involved in regulating the glial response to injury in the central nervous system.« less

Background. There are limited community based treatment services for drug dependence in India. Rural areas and urban resettlement colonies are in particular deficient in such services. Aims. The current study aimed at preliminary assessment of substance use disorder management services at a community based substance use treatment clinic in an urban resettlement colony. Methods. The study was carried out at community based substance use treatment centre in a resettlement colony in India. The records of the centre were chart reviewed. Results. A total of 754 patients were registered at the clinic during the study period. Heroin was the primary drug of abuse for 63% of the patients. The mean duration of follow-up for the patients with opioid and alcohol dependence was 13.47 (SD ± 10.37; range 0-39) months. A total of 220 patients of opioid dependence were prescribed substation or abstinence directed therapy. Buprenorphine (87), slow release oral morphine (SROM) (16), and dextropropoxyphene (98) were used for opioid substitution. Conclusion. It is possible to deliver substance use disorder treatment services in community setting. There is a need to develop area specific community based treatment services for substance abuse in socially disadvantaged populations such as urban resettlement colonies.

Over the last years, more stringent safety requirements for an increasing number of chemicals across many regulatory fields (e.g. industrial chemicals, pharmaceuticals, food, cosmetics, …) have triggered the need for an efficient screening strategy to prioritize the substances of highest concern. In this context, alternative methods such as in silico (i.e. computational) techniques gain more and more importance. In the current study, a new prioritization strategy for identifying potentially mutagenic substances was developed based on the combination of multiple (quantitative) structure-activity relationship ((Q)SAR) tools. Non-evaluated substances used in printed paper and board food contact materials (FCM) were selected for a case study. By applying our strategy, 106 out of the 1723 substances were assigned 'high priority' as they were predicted mutagenic by 4 different (Q)SAR models. Information provided within the models allowed to identify 53 substances for which Ames mutagenicity prediction already has in vitro Ames test results. For further prioritization, additional support could be obtained by applying local i.e. specific models, as demonstrated here for aromatic azo compounds, typically found in printed paper and board FCM. The strategy developed here can easily be applied to other groups of chemicals facing the same need for priority ranking. Copyright © 2017 Elsevier Ltd. All rights reserved.

Although research has documented the positive effects of family-based prevention programs, the field lacks specific information regarding why these programs are effective. The current study summarized the effects of family-based programs on adolescent substance use using a component-based approach to meta-analysis in which we decomposed programs into a set of key topics or components that were specifically addressed by program curricula (e.g., parental monitoring/behavior management, problem solving, positive family relations, etc.). Components were coded according to the amount of time spent on program services that targeted youth, parents, and the whole family; we also coded effect sizes across studies for each substance-related outcome. Given the nested nature of the data, we used hierarchical linear modeling to link program components (Level 2) with effect sizes (Level 1). The overall effect size across programs was .31, which did not differ by type of substance. Youth-focused components designed to encourage more positive family relationships and a positive orientation toward the future emerged as key factors predicting larger than average effect sizes. Our results suggest that, within the universe of family-based prevention, where components such as parental monitoring/behavior management are almost universal, adding or expanding certain youth-focused components may be able to enhance program efficacy.

The current study explored whether laboratory-based techniques can provide a strategy for studying client language as a mechanism of behavior change. Specifically, this study examined the potential of a simulation task to elicit healthy talk, or self-motivational statements in favor of healthy behavior, related to marijuana and alcohol use. Participants (N = 84) were adolescents reporting at least 10 lifetime substance use episodes recruited from various community settings in an urban Pacific Northwest setting. Participants completed the Adolescent Simulated Intoxication Digital Elicitation (A-SIDE), a validated paradigm for assessing substance use decision making in peer contexts. Participants responded to 4 types of offers in the A-SIDE: (a) marijuana, (b) food (marijuana control), (c) alcohol, and (d) soda (alcohol control). Using a validated coding scheme adapted for the current study, client language during a structured interview assessing participants' response to the simulated offers was evaluated. Associations between percent healthy talk (PHT, calculated by dividing the number of healthy statements by the sum of all substance-related statements) and cross-sectional outcomes of interest (previous substance use, substance use expectancies, and behavioral willingness) were explored. The frequency of substance-related statements differed in response to offer type; rate of PHT did not. PHT was associated with behavioral willingness to accept the offer. However, PHT was not associated with decontextualized measures of substance use. Associations between PHT and global expectancies were limited. Simulation methods may be useful in investigating the impact of context on self-talk and to systematically explore client language as a mechanism of change.

Substance use disorders are understood as a chronically relapsing condition that is difficult to treat. However, in recent years there have been promising developments in the treatment of substance use disorders, specifically with interventions based on mindfulness and acceptance and commitment therapy. Little research has examined whether these types of interventions may positively impact residential substance use treatment outcomes. Thus, in the current study we developed and examined, in a randomized controlled trial, a 4-week, eight-session, adjunctive mindfulness and acceptance group therapy for patients in residential substance use treatment. Our primary outcomes were substance use cravings, psychological flexibility, and dispositional mindfulness at treatment discharge. Patients (N = 117) from a private residential substance use facility were randomized to receive the adjunctive mindfulness and acceptance group or treatment-as-usual. Patients were assessed at treatment intake and at discharge from a 28-30-day residential program. Although treatment groups did not statistically differ at discharge on any primary outcome, small effect sizes favored the mindfulness and acceptance group on cravings and psychological flexibility. Conclusions/Importance: Continued research is needed to determine whether the addition of mindfulness and acceptance-based interventions improve outcomes long term following residential substance use treatment.

Meeting the substance abuse treatment needs of lesbian, bisexual and transgender women: implications from research to practice

PubMed Central

Stevens, Sally

2012-01-01

Research on the incidence, etiology and substance abuse treatment needs of lesbian, bisexual and transgender (LBT) women is limited. Most research indicates higher levels of alcohol and drug abuse among these populations compared to their heterosexual counterparts, with recent research indicating that substance abuse is a particular concern for transgender individuals and an increasing problem among younger LBT individuals. Risk factors and reasons for substance abuse among sexual minority women are similar to those of heterosexual women, yet are substantially complicated by issues of family rejection and lack of social support, stigma and minority stress, as well as abuse and harassment. Historically, substance abuse prevention, early intervention, and clinical treatment programs were designed to meet the needs of the sexual majority population with relatively few programs designed to incorporate the specific needs of sexual minorities. This article reviews findings from previous studies and utilizes new data collected from community-based and residential substance abuse treatment programs to (1) examine issues relevant to LBT women and substance use, and (2) make recommendations for tailoring substance abuse treatment programs to meet the needs of these populations.

Substance use disorders (SUDs) are highly prevalent among inpatient adolescents with psychiatric disorders. In this population, substance use and other psychiatric outcomes can reinforce one another. Despite the need for integrated interventions in youths with dual diagnoses, few specific instruments are available. App-based technologies have shown promising results to help reduce substance use in adolescents, but their applicability in youths with associated severe psychiatric disorders is poorly documented. We aim to evaluate the feasibility of an ecological momentary assessment (EMA) intervention for all substance users, and of a smartphone application for cannabis users (Stop-Cannabis), for outpatient treatment after hospital discharge. All inpatient adolescents with psychiatric disorders hospitalized between 2016 and 2018 in a university hospital will be systematically screened for SUD and, if positive, will be assessed by an independent specialist addiction team. Participants with confirmed SUDs will be invited and helped to download an EMA app and, if required, the Stop-Cannabis app, the week preceding hospital discharge. Information about the acceptability and use of both apps and the validity of EMA data in comparison to clinical assessments will be assessed after 6 months and 1 year. This research has been designed to raise specific issues for consideration regarding the sequence between substance use, contextual factors, and other psychiatric symptoms among adolescents with comorbid severe psychiatric disorders. A better understanding of the mechanisms involved will inform the development of integrated treatment for dual disorders at that age. The study has already been approved and granted. Dissemination will include presentations at international congresses as well as publications in peer-reviewed journals. European Clinical Trials Database: Number 2016-001999-30.

As part of the previous French Total Diet Studies (TDS) focusing on exposure to food chemicals in the population aged 3 years and older, the French Agency for Food, Environmental and Occupational Health & Safety (ANSES) launched a specific TDS on infants to complete its overall chemical food safety programme for the general population. More than 500 chemical substances were analysed in food products consumed by children under 3 years old, including nutrients, several endocrine disruptors resulting from human activities (polychlorinated biphenyls, dioxins and furans, brominated flame retardants, perfluoroalkyl acids, pesticide residues, etc.) or migrating from food contact materials such as bisphenol A or phthalates, but also natural substances such as mycotoxins, phytoestrogens and steroids. To obtain a representative and general view of infant food consumption, food items were selected based on results of a national consumption survey conducted specifically on this population. Moreover, a specific study on food was conducted on 429 households to determine which home-cooking practices are employed to prepare food consumed by infants. Overall, the targeted chemical substances were analysed in more than 450 food samples, representing the purchase and home-cooking practices of over 5500 food products. Foods included common foods such as vegetables, fruit or cakes as well as specific infant foods such as infant formula or jarred baby food. The sampling plan covered over 80% of the total diet. Specificities in infant food consumption and habits were therefore considered to define this first infant TDS. This study, conducted on a large scale and focusing on a particularly sensitive population, will provide accurate information on the dietary exposure of children under 3 years to food chemicals, especially endocrine disruptors, and will be particularly useful for risk assessment analysis under the remit of ANSES' expert committees.

Black gay and bisexual young men carry a disproportionate burden of HIV in the United States. This study explored Black gay and bisexual young men living with HIV’s identification and interpretation of race-specific cultural messages regarding substance use, sexual activity, and condom use. A total of 36 Black gay and bisexual young men living with HIV (ages 16-24, mean=20.6 years) from four geographically diverse regions of the US participated in qualitative in-depth interviews. Results from this study elucidate the ways in which these young men interpret various forms of race-specific cultural messages and experiences regarding substance use, sexual activity, and condom use. Participants discussed cultural messages and experiences promoting and discouraging condoms and substance use. Regarding sexual activity, only messages and experiences promoting sex were reported. Across all three categories, messages and experiences promoting risk were predominant. Data further revealed that socially transmitted cultural messages received by young men emanated from multiple sources, such as family, peers, sexual partners, community/neighborhood, and the broader society. Race-specific cultural messages and experiences should be addressed in interventions for this population, and programs should assist young men in developing a critical consciousness regarding these messages and experiences in order to promote health and well-being.

Although the use of illicit substances, particularly those commonly categorized as "club drugs", among men who have sex with men (MSM), is well established in the literature, little is known about the decision making process that is used in deciding whether or not to use a particular substance. In this study, we examine the positive and negative attitudes and perceptions among young men who have sex with men (YMSM) in regards to three specific drugs: crystal methamphetamine, cocaine and ecstasy. The findings reported here emerged from the baseline quantitative interviews and an accompanying qualitative phase of the Healthy Young Men's study (HYM), a longitudinal study examining risk and protective factors for substance use and sexual risk among an ethnically diverse sample of YMSM. Findings are discussed in relation to framing how service providers and others can design new and innovative interventions to prevent young men from initiating substance use.

Studies using embryos of the zebrafish Danio rerio (DarT) instead of adult fish for characterising the (eco-) toxic potential of chemicals have been proposed as animal replacing methods. Effect analysis at the molecular level might enhance sensitivity, specificity, and predictive value of the embryonal studies. The present paper aimed to test the potential of toxicoproteomics with zebrafish eleutheroembryos for sensitive and specific toxicity assessment. 2-DE-based toxicoproteomics was performed applying low-dose (EC(10)) exposure for 48 h with three-model substances Rotenone, 4,6-dinitro-o-cresol (DNOC) and Diclofenac. By multivariate "pattern-only" PCA and univariate statistical analyses, alterations in the embryonal proteome were detectable in nonetheless visibly intact organisms and treatment with the three substances was distinguishable at the molecular level. Toxicoproteomics enabled the enhancement of sensitivity and specificity of the embryonal toxicity assay and bear the potency to identify protein markers serving as general stress markers and early diagnosis of toxic stress.

Formation of extracellular polymeric substances from acidogenic sludge in H2-producing process.

PubMed

Sheng, Guo-Ping; Yu, Han-Qing

2007-02-01

In this study, the formation of extracellular polymeric substances (EPS) and surface characteristics of an acidogenic sludge in anaerobic H(2)-producing process was investigated. Results show that carbohydrates, proteins, and humic substances were the dominant components in bound EPS (BEPS), while in soluble EPS (SEPS), carbohydrates were the main component. The total content of BEPS initially increased but then kept almost unchanged during fermentation from 25 to 35 h; after that, it slightly decreased. The total content of SEPS increased to 172.5 +/- 0.05 mg C g(-1) volatile suspended solid with the time that increased to 23.5 h, and then rapidly decreased until 43 h; thereafter, it kept almost unchanged. The SEPS had good correlations with the specific H(2) production rate, substrate degradation rate, and specific aqueous products formation rate, but the BEPS seemed to have no such correlations with these specific rates. Results also confirm that part of EPS could be utilized by the H(2)-producing sludge. As the substrate was in short supply, the EPS would be hydrolyzed to sever as carbon and energy source.

The relationship between substance use and sexual health among African-American female adolescents with a history of seeking mental health services.

This study examined relationships between substance use patterns and problems and sexual health outcomes among low-income, urban, African-American female adolescents with a history of seeking mental health services. Participants were recruited from outpatient mental health clinics serving urban, primarily low-income youth and families in Chicago, Illinois, as part of a 2-year, longitudinal investigation of HIV risk behavior during which they completed interviews every 6 months (five time points). Girls who completed at least one follow-up interview were invited to participate in a sixth wave of assessment to assess trauma exposure, substance use problems, and sexual risk. The current study (n = 177) examined the association between sexual risk behavior and substance use problems reported at the most recent interview (ages 14-22) and substance use patterns and sexually transmitted infections (STI) reported at all six times points. Multiple regression examined the combined and unique effects of different patterns of substance use and substance use problems as correlates of sexual risk behavior and STIs. Substance use problems were associated with increased sexual risk behavior and increased likelihood of experiencing STIs. Substance use patterns were associated with sexual risk behavior. Results suggest that specific patterns of substance use and substance use problems are important to address in sexual health promotion among low-income, urban, African-American girls with a history of seeking mental health services. Understanding the nuances of these relationships is important in informing how to best serve this vulnerable group of adolescents who experience significant sexual risk and mental health care disparities.

Previous research suggests that perceptions of peer substance use are associated with personal use. Specifically, overestimating use in the peer group is predictive of higher rates of personal substance use. 'Social norms'-interventions are based on the premise that changing these misperceived social norms regarding substance use by providing feedback on actual norms is associated with a reduction in personal substance use. Studies conducted in the U.S.A. suggest that 'social norms'-feedback is an effective strategy for reducing substance use among university students. It is unknown whether the effects of a 'social norms'-feedback on substance use can be replicated in a sample of German university students. The objective of this article is to describe the study design and aims of the 'INternet-based Social norms-Intervention for the prevention of substance use among Students' (INSIST)-study, a cluster-controlled trial examining the effects of a web-based 'social norms'- intervention in students enrolled at four intervention universities with those enrolled at four delayed intervention control universities. The INSIST-study is funded by the German Federal Ministry of Health. Eight universities in four regions in Germany will take part in the study, four serving as intervention and four as delayed intervention control universities (randomly selected within a geographic region). Six hundred students will be recruited at each university and will be asked to complete a web-based survey assessing personal and perceived substance use/attitudes towards substance use at baseline. These data will be used to develop the web-based 'social norms'-feedback tailored to gender and university. Three months after the baseline survey, students at intervention universities will receive the intervention. Two months after the launch of the intervention, students of all eight universities will be asked to complete the follow-up questionnaires to assess changes in perceptions of/attitudes toward peer substance use and rates of personal substance use. This study is the first German cluster-controlled trial investigating the influence of a web-based 'social norms'-intervention on perceptions of/attitudes towards substance use and substance use behavior in a large university student sample. This study will provide new information on the efficacy of this intervention strategy in the German university context. DRKS00007635 at the 'German Clinical Trials Register' (17.12.2014).

[Epidemiology, etiology and treatment of patients with psychosis and co-morbid substance use disorder].

Epidemiology, etiology and treatment of patients with psychosis and co-morbid substance use disorder Abstract. More than 25 years ago, when the research on the efficacy of treatments for patients with a comorbidity of psychosis and substance use disorder has been systematically started, some authors described the treatment of these patients as a "mission impossible". Approximately half of all individuals with schizophrenia develop substance use disorders in the course of their life; about one third of them a comorbid alcohol use disorder and about one quarter a comorbid substance use disorder with other addictive substances. There is no universally valid aetiology model to explain the relationship between psychosis and addiction. Contrary to expectations, the self-medication model was not empirically confirmed, while the psychological affect regulation model, the vulnerability-stress model of a specific sensitivity to addictive substances given a predisposition of psychosis, or the neurobiological common factor model of a dysfunction of dopamine regulation in the mesocorticolimbic reward system that predispose to primary substance use disorder found some empirical support. Research on the psychosocial-psychotherapeutic and pharmacological treatment of patients with psychosis and addiction are so heterogeneous in terms of characteristics of patients, disorders, treatments, settings and outcomes that hardly two comparable studies can be found. Thus, it is hardly possible to make scientifically based statements on the efficacy and effectiveness of therapies. Integrative treatment programs are promising, which combine psycho- and pharmacotherapeutic interventions for the treatment of psychotic and substance use disorders in a coherent manner and which can be flexibly adapted to the individual patient's needs. Such treatments are carried out at the same time, in the same setting and by the same treatment providers and practioners. Successful integrative treatment programs usually include motivational interventions, cognitive-behavioral interventions specific to schizophrenia and addiction, interventions that may reduce the substance use such as relapse prevention, contingency management and / or family interventions. These interventions are best combined with second-generation antipsychotics, if necessary with medication to reduce substance use. Although no "mission impossible" treating patients with psychosis and addiction remains a complex challenge for research and practice.

Objective Despite the known association between substance use disorders (SUD) and major depressive disorder (MDD) among adolescents, little is known regarding substance use among adolescents with MDD. Method Youth with MDD who had not improved after an adequate SSRI trial (N = 334) were enrolled in the Treatment of SSRI-Resistant Depression in Adolescents (TORDIA) trial. Analyses examined substance use (via the Drug Use Severity Index) and changes therein in relation to treatment and depressive symptoms. Adolescents meeting SUD criteria via the Schedule for Affective Disorders and Schizophrenia for School-Age Children-Present and Lifetime version at baseline were excluded. Results Substance use was common: 28.1% reported repeated experimentation at baseline. Substance-related impairment was associated with baseline depression severity, older age, physical/sexual abuse, family conflict, hopelessness, and comorbid oppositional defiant disorder/conduct disorder. There was significant improvement in substance-related impairment among adolescents who responded to MDD treatment. Baseline suicidal ideation was higher among subjects who progressed to high substance-related impairment (≥75th percentile) versus those whose substance-related impairment remained low (<75th percentile), and parental depressive symptoms predicted persistence of high substance-related impairment during the study. MDD response was best among adolescents with low 12-week substance-related impairment scores regardless of whether they had high or low baseline substance-related impairment. There were no significant differential effects of specific treatments, pharmacological or CBT, on substance use. Conclusions Substance use is common among adolescents with treatment-resistant MDD. Subjects who had persistently low substance-related impairment or who demonstrated reduced substance-related impairment had better MDD treatment response, although the direction of this association is uncertain.

Religiosity is a well-established protective factor against substance use among Caucasians, but limited research has examined its role among Asian Americans. The purposes of this study were (1) to examine whether the associations between religiosity and substance use outcomes differed across Caucasians and Asian Americans, and (2) to test whether acculturation moderated the associations between religiosity and substance use outcomes among Asian Americans. We utilized a large and diverse cross-sectional sample of 839 college students to test whether race moderated the associations between religiosity and substance use outcomes (Study 1). We then replicated and extended our findings in a separate college sample of 340 Asian Americans, and examined the moderating role of acculturation on the associations between religiosity and substance use outcomes (Study 2). Controlling for age, gender, and paternal education, religiosity was protective against alcohol use, alcohol problems, and marijuana use among Caucasians but was unrelated to these outcomes among Asian Americans in Study 1. In Study 2, religiosity was protective against alcohol problems only at high levels of acculturation. Moreover, religiosity was protective against marijuana use at both high and mean levels of acculturation, but not at low levels of acculturation. The protective effects of religiosity on alcohol use and problems varied across Caucasian and Asian American college students, and religiosity protected against alcohol problems and marijuana use only among more acculturated Asian Americans. These findings underscore the need to examine culturally-specific correlates of substance use outcomes among Asian Americans. Copyright © 2012 Elsevier Ireland Ltd. All rights reserved.

Depression, Craving and Substance Use Following a Randomized Trial of Mindfulness-Based Relapse Prevention

PubMed Central

Witkiewitz, Katie; Bowen, Sarah

2012-01-01

Objective A strong relation between negative affect and craving has been demonstrated in laboratory and clinical studies, with depressive symptomatology showing particularly strong links to craving and substance abuse relapse. Mindfulness-Based Relapse Prevention (MBRP), shown to be efficacious for reduction of substance use, uses mindfulness-based practices to teach alternative responses to emotional discomfort and lessen the conditioned response of craving in the presence of depressive symptoms. The goal of the current study was to examine the relation between measures of depressive symptoms, craving, and substance use following MBRP. Methods Individuals with substance use disorders (N=168; age 40.45, (SD=10.28); 36.3% female; 46.4% nonwhite) were recruited after intensive stabilization, then randomly assigned to either eight weekly sessions of MBRP or a treatment-as-usual control group. Approximately 73% of the sample was retained at the final four-month follow-up assessment. Results Results confirmed a moderated-mediation effect, whereby craving mediated the relation between depressive symptoms (Beck Depression Inventory) and substance use (Time Line Follow Back) among the treatment-as-usual group, but not among MBRP participants. Specifically, MBRP attenuated the relation between postintervention depressive symptoms and craving (Penn Alcohol Craving Scale) two months following the intervention (f2=.21). This moderation effect predicted substance use four-months following the intervention (f2=.18). Conclusion MBRP appears to influence cognitive and behavioral responses to depressive symptoms, partially explaining reductions in postintervention substance use among the MBRP group. Although preliminary, the current study provides evidence for the value of incorporating mindfulness practice into substance abuse treatment and identifies one potential mechanism of change following MBRP.

Miller, Adam Bryant; Williams, Caitlin; Day, Catherine; Esposito-Smythers, Christianne

2017-06-01

The purpose of the present study was to examine whether cognitive distortions (e.g., cognitive errors; negative views of self, world, and future) influence the association between dating violence and problematic substance use behaviors in a sample of psychiatrically hospitalized adolescents. Participants included 155 adolescents, aged 13-17 years, who had initiated dating. Adolescents completed measures of dating violence, substance-related problems (alcohol and marijuana), and cognitive distortions. Logistic regressions were conducted to examine the direct and interactive effects of dating violence exposure and cognitive distortions on likelihood of recent problematic substance use. Results suggested a main effect of dating violence on problematic alcohol and other drug use as well as an interactive effect of dating violence and cognitive distortions. Specifically, the relationship between dating violence and odds of substance-related problems was higher among those with greater (vs. fewer) cognitive distortions. Study results suggest the need for careful screening of cognitive distortions among adolescent dating violence victims, particularly those in mental health treatment. © 2016 Wiley Periodicals, Inc.

Taylor, Matthew J; Merritt, Stephanie M; Brown, Carrie M

2012-01-01

The purpose of this study was to investigate the premise that adolescent perceptions of family caring are a precipitating source of substance use deterrence. More specifically, this study examined the role of family caring on communication of substance use harm and sanctions of use and the effect of these on peer substance involvement and individual use outcomes. A sample of rural dwelling African American and White 7th and 8th grade students (N = 1780) was assessed through self-report. It was anticipated that family caring would be positively related to harm communication and sanctions of use, and that these would be negatively related to peer substance involvement and individual use. Results suggest that family caring was positively linked to harm communication and sanctions of use, and that these were both negatively related to peer substance involvement and individual use. Several significant race differences were noted, which suggest differential associations between some variables. Results are discussed in terms of these race differences, as well as in terms of rural residency.

The Impact of Ethnoracial Appearance on Substance Use in Mexican Heritage Adolescents in the Southwest United States

PubMed Central

Ayers, Stephanie L.; Kulis, Stephen; Marsiglia, Flavio F.

2013-01-01

Latinos are a multiracial ethnic group, and as such, within-group differences in ethnoracial appearance deserve to be studied and understood within the racialized American context and in connection to specific health and mental health outcomes. This article presents the findings of a study conducted with middle school Mexican heritage students (n = 1,150) in Phoenix, Arizona, and tested how non-White majority ethnoracial appearance predicted adolescent substance use, and whether the relationship differed by generation status and strength of ethnic identity. Logistic regression results revealed that generation status and ethnic identity moderate the relationship between ethnoracial appearance and substance use among Mexican heritage youth. The odds of using substances were significantly higher for third-generation adolescents who reported a less European appearance, but significantly lower for second-generation youth who were more indigenous in appearance. These findings indicate that a stronger indigenous ethnic appearance can be both a protective and risk factor for substance use for adolescents. Implications are discussed in terms of incorporating ethnoracial appearance content in prevention interventions for Mexican heritage and other Latino adolescents. PMID:24403723

Emotional and Psychosocial Factors Associated With Drunkenness and the Use of Tobacco and Cannabis in Adolescence: Independent or Interactive Effects?

García-Moya, Irene; Ortiz Barón, María José; Moreno, Carmen

2017-07-03

Although previous research has examined emotional and psychosocial factors associated with substance use, there is a paucity of studies examining both at the same time, and insufficient attention has been paid to how these factors may interact. The aim of this study was to simultaneously examine the contributions from emotional (emotional control and depression) and psychosocial (peers' conventional behavior, peers' substance use and parent-child relationships) factors to drunkenness and the use of tobacco and cannabis in adolescence. Sample consisted of 1,752 adolescents aged 15 to 16 years who had participated in the 2014 edition of the WHO Health Behaviour in School-aged Children survey in Spain. Data were collected by means of anonymous online questionnaires, and hierarchical multiple regression models (with sex and age as controls and including interactions among the examined predictors) were used for statistical analysis. Emotional and psychosocial factors showed significant interactive effects on substance use. Emotional control, which tended to buffer the effects of potential risk factors, and peers' substance use were consistent predictors of substance use. In contrast, the role of other factors depended on the substance under study, with depression and peers' conventional behavior being part of interactive terms for tobacco use and cannabis use only, and the quality of parent-child relationships being absent from the final model on cannabis use. Conclusions/Importance: Exploring interactions and potential substance-specific effects is fundamental to reach a better understanding of how emotional and psychosocial factors work in concert relative to substance use in adolescence.

In the substance abuse treatment field, the annual turnover rate is cited as being anywhere between 19 and 50 percent (Johnson & Roman, 2002; Gallon, Gabriel, & Knudsen, 2003; Knudsen et al., 2003; McLellan et al., 2003). However, no research to date has evaluated these claims by tracking turnover longitudinally using organizational turnover data from substance abuse treatment centers. This research presents the results of a longitudinal study designed to systematically examine actual turnover among counselors and clinical supervisors. Twenty-seven geographically dispersed treatment organizations, serving a wide range of clients in the public and private sector, provided data for the study over a two year time span (2008–2009). The annual turnover rate was 33.2% for counselors and 23.4% for clinical supervisors. For both groups the majority of turnover was voluntary (employee-initiated). Specific reasons for turnover were largely consistent across the two groups, with the most common reason being a new job or new opportunity. The findings are discussed in terms of the unique employment context of substance abuse treatment. Practical recommendations are also discussed to help stem the tide of turnover in the field of substance abuse treatment. PMID:20675097

Sex differences in neurobiological mechanisms of substance dependence are well documented but studies of sex differences in associated neurocognitive deficits have produced inconsistent results. Posttraumatic stress disorder (PTSD) is comorbid with substance dependence and frequently affects neurocognition. Thus, we investigated the effects of sex and PTSD symptoms on sustained attention and inhibition abilities among 126 female and 297 male substance-dependent individuals (SDIs) using the Immediate Memory Test (IMT). Females with significant PTSD (PTSD+) symptoms demonstrated significantly impaired IMT performance relative to other participants. These results represent progress in efforts to delineate sex-specific risk factors for neurocognitive deficits among SDIs.

The following study presents factors influencing the decision to use/not to use new psychoactive substances (NPS), various patterns of NPS use, the problems experienced by users, and the methods for reducing the risks associated with NPS use. The study seeks to provide an in-depth look into the characteristics of NPS use and support the planning of targeted interventions in the field of NPS. The study involved 19 in-depth interviews carried out with 25 individuals divided into three subsamples in order to gain insight into the various experiences of NPS users. The interviews were conducted in Slovenia between December 2013 and October 2014. The sample was obtained by using the convenience sampling and snowball sampling methods. The main pattern of NPS use determined by the study concerned synthetic cathinones, specifically 3-MMC, with binge use spanning several days being a prominent feature. The main risks involving NPS use were: mixing various drugs, inappropriate dosing, lack of information prior to use, and the use of unknown substances. Several users spoke about effective strategies for reducing risks, such as obtaining information beforehand, using one's own implements and using only small quantities of unknown substances. Conclusions/Importance: The study revealed various factors based on which users decide to use NPS. Furthermore, users reported a number of problems resulting from NPS use, while risk reduction strategies are employed to a much lesser extent. Based on the results obtained, specific intervention efforts concerning NPS use and targeting specific groups of younger users were designed.

Agonist-induced internalization of the substance P (NK1) receptor expressed in epithelial cells.

1994-10-01

Internalization of the NK1 receptor (NK1R) and substance P was observed in cells transfected with cDNA encoding the rat NK1R by using anti-receptor antibodies and cyanine 3-labelled substance P (cy3-substance P). After incubation at 4 degrees C, NK1R immunoreactivity and cy3-substance P were confined to the plasma membrane. Within 3 min of incubation at 37 degrees C, NK1R immunoreactivity and cy3-substance P were internalized into small intracellular vesicles located beneath the plasma membrane. Fluorescein isothiocyanate-labelled transferrin and cy3-substance P were internalized into the same vesicles, identifying them as early endosomes. After 60 min at 37 degrees C, NK1R immunoreactivity was detected in larger, perinuclear vesicles. Internalization of 125I-labelled substance P was studied by using an acid wash to dissociate cell-surface label from that which has been internalized. Binding reached equilibrium after incubation for 60 min at 4 degrees C with no detectable internalization. After 10 min incubation at 37 degrees C, 83.5 +/- 1.0% of specifically bound counts were internalized. Hyperosmolar sucrose and phenylarsine oxide, which are inhibitors of endocytosis, prevented internalization of 125I-labelled substance P and accumulation of NK1R immunoreactivity into endosomes. Acidotropic agents caused retention of 125I-labelled substance P within the cell and inhibited degradation of the internalized peptide. Continuous incubation of cells with substance P at 37 degrees C reduced 125I-substance P binding at the cell surface. Therefore, substance P and its receptor are internalized into early endosomes within minutes of binding, and internalized substance P is degraded. Internalization depletes NK1Rs from the cell surface and may down-regulate the response of a cell to substance P.

Neutral endopeptidase-like enzyme controls the contractile activity of substance P in guinea pig lung.

PubMed Central

Stimler-Gerard, N P

1987-01-01

The responsiveness of isolated guinea pig lung parenchymal strips to substance P was enhanced by at least 100-fold in the presence of the endopeptidase inhibitors phosphoramidon (1 microM) or thiorphan (1 microM), but not with the converting enzyme inhibitor, captopril, or an inhibitor of serum carboxypeptidase N (both 1 microM). Responses of guinea pig tracheal rings to substance P were also markedly potentiated by phosphoramidon. The increase in tissue responsiveness by these inhibitors was relatively specific for substance P among several other spasmogenic peptides, including formyl-methionyl-leucyl-phenylalanine and the complement peptides C3a and C5a. The enhanced responses appear to result from a decrease in the rate of substance P degradation in the presence of neutral endopeptidase inhibitors. Specific binding of substance P to its receptor on bronchial membranes was increased by three- to fourfold in the presence of phosphoramidon. These data demonstrate an enhanced potential for substance P to contract lung tissues when degradation by a neutral endopeptidase-like enzyme is blocked. PMID:2438306

Substance abuse in Egypt is a serious public health threat. Recent studies have demonstrated increases in the prevalence of the use of tobacco, illegal drugs, and over-the-counter drugs, particularly among youth. We conducted focus groups with a total of 40 male and female youth participants, ages 12-14 and 15-18, recruited from two different areas (Cairo and Alexandria) in 2012. We investigated their knowledge and perceptions regarding current substance use, its sources, and promoting and protecting factors, broadly addressing the use of tobacco products, illicit and prescription drugs, inhaled substances such as glue and solvents, and alcohol. Our findings suggest that: (1) youth in Egypt had access to and were actively using substances encountered in similar research worldwide, including tobacco, alcohol, illicit drugs, glue sniffing, and pharmaceutical agents; (2) smoking cigarettes and using hashish were the most common practices, and Tramadol was the most commonly used pharmaceutical drug; (3) peer pressure from friends stood out as the most common reason to start and continue using substances, followed by adverse life events and having a parent or family member who used substances; (4) strict parenting, religiosity, and having non-user friends were among the factors perceived by youth to prevent substance use or help them quit using substances; (5) most youths were aware of the adverse health effects of substance use. These findings will inform the design of quantitative surveys aimed at estimating the prevalence of specific behaviors related to substance use among youth and potential avenues for prevention.

Psychiatric comorbidity and acculturation stress among Puerto Rican substance abusers.

Conway, Kevin P; Swendsen, Joel D; Dierker, Lisa; Canino, Glorisa; Merikangas, Kathleen R

2007-06-01

Although acculturation to the United States has been associated with an increase in substance, mood, and anxiety disorders in Latino populations, few studies have examined this concept relative to comorbidity among these syndromes. This study compares the prevalence and patterns of psychiatric comorbidity among Puerto Ricans with substance use disorders living in San Juan (Puerto Rico) to those who have migrated to New Haven (Connecticut) and examines the association between acculturation-related stress and the prevalence and patterns of psychiatric comorbidity among those who have migrated to New Haven. Lifetime levels of nearly all comorbid psychiatric disorders among respondents with substance use disorders were generally similar across sites. However, the risk of any co-occurring psychiatric disorder was higher among substance use disorder cases in New Haven who reported high levels of total acculturation stress and family-specific acculturation stress. These findings were generally accounted for by associations between affective disorders and high scores on these indicators of acculturation stress. The overall prevalence and patterns of psychiatric comorbidity are remarkably similar among Puerto Rican substance abusers whether they live in San Juan or have migrated to New Haven, thereby demonstrating robustness to differences in geographic location. Nevertheless, the degree of acculturation-related family stress is positively associated with co-occurring substance and psychiatric disorders, particularly affective disorders. Intervention in family strain related to the acculturation process may diminish the development of comorbid mental disorders and assist in implementing successful treatment of substance abuse.

A parallel process growth mixture model of conduct problems and substance use with risky sexual behavior.

Wu, Johnny; Witkiewitz, Katie; McMahon, Robert J; Dodge, Kenneth A

2010-10-01

Conduct problems, substance use, and risky sexual behavior have been shown to coexist among adolescents, which may lead to significant health problems. The current study was designed to examine relations among these problem behaviors in a community sample of children at high risk for conduct disorder. A latent growth model of childhood conduct problems showed a decreasing trend from grades K to 5. During adolescence, four concurrent conduct problem and substance use trajectory classes were identified (high conduct problems and high substance use, increasing conduct problems and increasing substance use, minimal conduct problems and increasing substance use, and minimal conduct problems and minimal substance use) using a parallel process growth mixture model. Across all substances (tobacco, binge drinking, and marijuana use), higher levels of childhood conduct problems during kindergarten predicted a greater probability of classification into more problematic adolescent trajectory classes relative to less problematic classes. For tobacco and binge drinking models, increases in childhood conduct problems over time also predicted a greater probability of classification into more problematic classes. For all models, individuals classified into more problematic classes showed higher proportions of early sexual intercourse, infrequent condom use, receiving money for sexual services, and ever contracting an STD. Specifically, tobacco use and binge drinking during early adolescence predicted higher levels of sexual risk taking into late adolescence. Results highlight the importance of studying the conjoint relations among conduct problems, substance use, and risky sexual behavior in a unified model. Copyright © 2010 Elsevier Ireland Ltd.

Hospital discharge may be an opportunity to intervene among patients with substance use disorders to reduce subsequent hospital utilization. This study determined whether having a substance use disorder diagnosis was associated with subsequent acute care hospital utilization. We conducted an observational cohort study among 738 patients on a general medical service at an urban, academic, safety-net hospital. The main outcomes were rate and risk of acute care hospital utilization (emergency department visit or hospitalization) within 30 days of discharge. The main independent variable was presence of a substance use disorder primary or secondary discharge diagnosis code at the index hospitalization. At discharge, 17% of subjects had a substance use disorder diagnosis. These patients had higher rates of recurrent acute care hospital utilization than patients without substance use disorder diagnoses (0.63 vs 0.32 events per subject at 30 days, P < 0.01) and increased risk of any recurrent acute care hospital utilization (33% vs 22% at 30 days, P < 0.05). In adjusted Poisson regression models, the incident rate ratio at 30 days was 1.49 (95% confidence interval, 1.12-1.98) for patients with substance use disorder diagnoses compared with those without. In subgroup analyses, higher utilization was attributable to those with drug diagnoses or a combination of drug and alcohol diagnoses, but not to those with exclusively alcohol diagnoses. Medical patients with substance use disorder diagnoses, specifically those with drug use-related diagnoses, have higher rates of recurrent acute care hospital utilization than those without substance use disorder diagnoses.

Latent growth trajectories of substance use among pregnant and parenting adolescents.

We examine changes among adolescent girls in substance use during pregnancy and the postpartum period. Three separate latent growth curve analyses assessed the impact of psychosocial, behavioral, and sociodemographic factors on resumption of or change in use of cigarettes, alcohol, and marijuana. The Vulnerable Populations Model for Research and Clinical Practice (Flaskerud & Winslow, 1998) provided the theoretical foundation for this study. This is a secondary analysis of data from a sample of 305 ethnic minority females (245 Latina, 60 African American), aged 13-18 years, who were pregnant at baseline and were participating in an HIV prevention study conducted in inner-city alternative schools in Los Angeles County. Data collected at 4 time points captured changes in substance use from pregnancy through the postpartum period. Baseline predictors included ethnicity/race, partner substance use, childhood abuse history, religiosity, acculturation, depressive symptoms, length of gestation at baseline, and previous substance use. Common predictors of greater resumption and/or greater level of use included greater history of use before pregnancy, partner substance use, childhood abuse, and a longer time since childbirth. African Americans were more likely to be smoking at baseline when they were still pregnant and to use marijuana postpartum; Latinas were more likely to use alcohol over the course of pregnancy and postpartum. Other variables exerted an influence on specific substances. For instance, religiosity impacted cigarette and alcohol use. Findings may assist prenatal care providers to identify and counsel pregnant adolescents at risk for perinatal substance use and to prevent resumption or initiation of substance use after childbirth.

Measuring Peer Socialization for Adolescent Substance Use: A Comparison of Perceived and Actual Friends’ Substance Use Effects

PubMed Central

Deutsch, Arielle R.; Chernyavskiy, Pavel; Steinley, Douglas; Slutske, Wendy S.

2015-01-01

Objective: There has been an increase in the use of social network analysis in studies of peer socialization effects on adolescent substance use. Some researchers argue that social network analyses provide more accurate measures of peer substance use, that the alternate strategy of assessing perceptions of friends’ drug use is biased, and that perceptions of peer use and actual peer use represent different constructs. However, there has been little research directly comparing the two effects, and little is known about the extent to which the measures differ in the magnitude of their influence on adolescent substance use, as well as how these two effects may be redundant or separate constructs. Method: Using Waves I and II of the National Longitudinal Study of Adolescent Health (Add Health) saturated subsample, we directly compared effects of perception of friends’ use (PFU) and actual friends’ use (AFU) on alcohol, cigarette, and marijuana initiation and persistence of use 1 year later. We also examined potential moderating effects of friendship quality and individual use on the relationship between perceived and actual friends’ substance use and outcomes. Results: Results indicated that, overall, PFU effects were larger than AFU effects; however, these effects did not significantly differ in magnitude for most models. In addition, interaction effects differed for different substances and usage outcomes, indicating the meaning of PFU and AFU constructs (and thus, different types of peer socialization) may change based on substance and type of use. Conclusions: These results highlight the multifaceted nature of peer influence on substance use and the importance of assessing multiple aspects of peer socialization while accounting for distinct contexts related to specific substances and use outcomes.

Recent research has suggested that the prevalence of problematic substance use within the Asperger syndrome population has previously been underestimated. Furthermore, there is some indication that problematic substance use might take place to manage the traits of Asperger syndrome; however this possibility has yet to be examined in detail. This study aimed to address this omission by exploring individuals' perceptions of their substance use in relation to their diagnosis of Asperger syndrome. Eight participants were recruited from either a specialist Asperger syndrome service or a drug and alcohol service. Participants were interviewed regarding their views of which factors led to their development and maintenance of problematic substance use, specifically in relation to their experience of having been diagnosed with Asperger syndrome. Thematic analysis was conducted on the interview transcripts. Six main themes were identified: self-medication; social facilitation; discrepancy between need and support; defining problematic substance use; substance use of peers, and recreational use of substances. The two themes of social facilitation and self-medication are focused on within this paper as they most closely reflect the more prominent bodies of literature in relation to the research aim. Participants reported that substances were used to act as a social facilitator to compensate for social deficits by increasing confidence in social settings and increasing participants' ease with which they communicate. The self-medication of psychological distress was reported and was associated with depression, anxiety and sleep difficulties. The study ends with a reflection on the method of data collection, the implications for clinical practice and suggestions for future research. Copyright © 2015 Elsevier B.V. All rights reserved.

Substance use and abuse, which includes alcohol use, alcohol dependence, drug use, and drug dependence, inflicts a substantial toll on Americans. Although studies have demonstrated the protective effect of social support, such as religious participation and via marriage, understanding their influence on racial and ethnic minorities is limited. Thus, the aim of this study is to assess the impact of social support on substance use and abuse in racial and ethnic minorities. The Collaborative Psychiatric Epidemiology Surveys, sponsored by the National Institute of Mental Health, a repository of race, ethnicity, and mental health data, was leveraged to develop four models using multivariate analysis, specifically logistic regression to estimate the probability of meeting the criteria for substance use and abuse. Racial and ethnic minorities were found to have lower rates of substance use and abuse compared to Whites, and foreign-born individuals were consistently less likely to use or abuse substances compared to American-born minorities. Mental health conditions were highly associated with substance use and abuse, and social support by way of religious participation and marriage was protective against substance use and abuse. In racial and ethnic minorities, nativity and social support were protective against substance use and abuse; however, these protective factors did not completely eliminate risk. Thus, although race and ethnicity are important to understanding health outcomes and health behaviors, such as substance use and abuse, it is the intersection of multiple factors, representing internal and external forces, which may be more informative and offer a more comprehensive picture of the landscape influencing drug and alcohol use and dependence. Targeted interventions should consider leveraging religious spaces and bilingual materials when attempting to reach racial and ethnic minorities.

This pilot study examined pre to post-change of patients in a substance use residential treatment center that incorporated Dialectical Behavior Therapy with specific cultural, traditional and spiritual practices for American Indian/Alaska Native adolescents. Specifically, the incorporation of cultural, spiritual and traditional practices was done while still maintaining fidelity to the evidence based treatment (DBT). 229 adolescents participated in the study and were given the Youth Outcome Questionnaire-Self-Report version at pre-treatment and post-treatment and the total scores were compared. The results of the research study showed that 96% of adolescents were either "recovered" or "improved" using clinical significant change criteria. Additionally, differences between the group's pre-test scores and post-test scores were statistically significant using a matched standard T-test comparison. Finally, the effect size that was calculated using Cohen's criteria was found to be large. The results are discussed in terms of the implication for integrating western and traditional based methods of care in addressing substance use disorders and other mental health disorders with American Indian/Alaska Native adolescents.

Objective This study investigated associations between the use of alternative tobacco products (e.g., cigarettes, little cigars/cigarillos, hookah, e-cigarettes), alcohol, and marijuana among college students and use by their parents, siblings, and friends. A large literature exists for social influences on adolescent substance use, but few studies have focused on college samples. Participants 3,418 college students from seven universities in the state of Georgia participated in this study. Methods Web-based surveys were completed by students (45–60 minutes) during the fall semester, 2014. Results Findings largely indicated specificity of associations between college student use and use by social influences for similar tobacco products and other substances. For each tobacco product or substance, the highest associations were for friends'use. Structural equation analyses further supported the specificity of associations and highlighted the relative strength of friends' use on student use. Conclusion Similar to findings with adolescents, the use of alternative tobacco products, alcohol, and marijuana by parents, siblings, and friends is associated with higher levels of use among college students, and friends' use was the most potent correlate for this phase of the lifespan.

In the interest of improving child maltreatment prevention science, this longitudinal, community based study of 499 mothers and their infants tested the hypothesis that mothers’ childhood history of maltreatment would predict maternal substance use problems, which in turn would predict offspring victimization. Mothers (35% White/non-Latina, 34% Black/non-Latina, 23% Latina, 7% other) were recruited and interviewed during pregnancy, and child protective services records were reviewed for the presence of the participants’ target infants between birth and age 26 months. Mediating pathways were examined through structural equation modeling and tested using the products of the coefficients approach. The mediated pathway from maternal history of sexual abuse to substance use problems to offspring victimization was significant (standardized mediated path [ab]=.07, 95% CI [.02, .14]; effect size=.26), as was the mediated pathway from maternal history of physical abuse to substance use problems to offspring victimization (standardized mediated path [ab]=.05, 95% CI [.01, .11]; effect size =.19). There was no significant mediated pathway from maternal history of neglect. Findings are discussed in terms of specific implications for child maltreatment prevention, including the importance of assessment and early intervention for maternal history of maltreatment and substance use problems, targeting women with maltreatment histories for substance use services, and integrating child welfare and parenting programs with substance use treatment.

The Alcohol, Smoking and Substance Involvement Screening Test (ASSIST) is a screening instrument to detect substance use in primary care (PC). To screen for illicit substances (excluding tobacco and alcohol), the ASSIST consists of 8-57 questions and requires complicated scoring. To improve the efficiency of screening of drug misuse in PC, this study constructed and validated a two-item screen for drug use from the ASSIST. Guided by previous reviews, the ASSIST was revised. Patients were recruited in VA primary care clinics (N=1283). Half of the sample was used to develop the ASSIST-Drug; the other half was used to validate it. The Mini International Neuropsychiatric Interview (MINI) and the Inventory of Drug Use Consequences were the criterion measures. A brief, two-item ASSIST-Drug was constructed. Based on the development sample, the ASSIST-Drug was 94.1% sensitive and 89.6% specific for drug use disorders. Based on the validation sample, it was 95.4% sensitive and 87.8% specific. The ASSIST-Drug also had comparable sensitivity and specificity to identify drug use negative consequences, as well as for diverse subgroups of patients in terms of gender, age, race/ethnicity, marital status, educational levels, and post traumatic stress disorder status. The ASSIST-Drug may be a useful screening tool for PC settings. It is reliable, brief, and easy to remember, administer and score. It is sensitive and specific for drug use disorders and drug use negative consequences, and the predictive properties are consistent across subgroup of patients. Published by Elsevier Ireland Ltd.

Prescription-drug use in the USA has increased by more than 60% in the last three decades. Prevalence of prescription-drug use among pregnant women is currently estimated around 50%. Prevalence of illicit drug use in the USA is 14.6% among pregnant adolescents, 8.6% among pregnant young adults and 3.2% among pregnant adults. The first step in identifying problematic drug use during pregnancy is screening; however, no specific substance-use screener has been universally recommended for use with pregnant women to identify illicit or prescription-drug use. This study compares and validates three existing substance-use screeners for pregnancy-4 P's Plus, National Institute on Drug Abuse (NIDA) Quick Screen/Alcohol, Smoking, and Substance Involvement Screening Test (ASSIST) and the Substance Use Risk Profile-Pregnancy (SURP-P) scale. This is a cross-sectional study designed to evaluate the sensitivity, specificity and usability of existing substance-use screeners. Recruitment occurs at two obstetrics clinics in Baltimore, Maryland, USA. We are recruiting 500 participants to complete a demographic questionnaire, NIDA Quick Screen/ASSIST, 4 P's Plus and SURP-P (ordered randomly) during their regularly scheduled prenatal appointment, then again 1 week later by telephone. Participants consent to multidrug urine testing, hair drug testing and allowing access to prescription drug and birth outcome data from electronic medical records. For each screener, reliability and validity will be assessed. Test-retest reliability analysis will be conducted by examining the results of repeated screener administrations within 1 week of original screener administrations for consistency via correlation analysis. Furthermore, we will assess if there are differences in the validity of each screener by age, race and trimester. This study is approved by the Institutional Review Board of the University of Maryland (HP-00072042), Baltimore, and Battelle Memorial Institute (0619-100106433).
