  11. Kernel Equating Under the Non-Equivalent Groups With Covariates Design

    PubMed Central

    Bränberg, Kenny

    2015-01-01

    When equating two tests, the traditional approach is to use common test takers and/or common items. Here, the idea is to use variables correlated with the test scores (e.g., school grades and other test scores) as a substitute for common items in a non-equivalent groups with covariates (NEC) design. This is performed in the framework of kernel equating and with an extension of the method developed for post-stratification equating in the non-equivalent groups with anchor test design. Real data from a college admissions test were used to illustrate the use of the design. The equated scores from the NEC design were compared with equated scores from the equivalent group (EG) design, that is, equating with no covariates as well as with equated scores when a constructed anchor test was used. The results indicate that the NEC design can produce lower standard errors compared with an EG design. When covariates were used together with an anchor test, the smallest standard errors were obtained over a large range of test scores. The results obtained, that an EG design equating can be improved by adjusting for differences in test score distributions caused by differences in the distribution of covariates, are useful in practice because not all standardized tests have anchor tests.

    PubMed Central

    Kim, Giyeon; DeCoster, Jamie; Bryant, Ami N.; Ford, Katy L.

    2017-01-01

    This study examined the measurement equivalence of the K6 across diverse racial/ethnic and linguistic groups in the U.S. differential item functioning analyses using item response theory were conducted among 44,846 U.S. adults drawn from the California Health Interview Survey. Results show that four items (“nervous,” “restless,” “depressed,” and “everything an effort”) varied significantly across races/ethnicities and four items (“nervous,” “hopeless,” “restless,” and “depressed”) varied significantly across languages. In additional effect size analyses designed to separate effects of race/ethnicity from language, the structure of the White English group was substantially different from both the Hispanic/Latino English group and Hispanic/Latino Spanish group, whereas the Hispanic/Latino Spanish group was not different from the Hispanic/Latino English group. The findings suggest that there was evident measurement nonequivalence in the K6 among racially/ethnically and linguistically diverse adults and that the observed nonequivalence in the K6 appears to be driven by language rather than race/ethnicity.

    2007-01-01

    Although many pregnant women experience back pain, it has not considered an important health problem. No study has investigated the effects of a back-pain-reducing program (BPRP) during pregnancy for Korean women. The purpose of this study was to evaluate the effect of a program designed to reduce back pain in pregnant women. A non-equivalent control-group pretest-posttest design was used. Pregnant women who attended an antenatal clinic and experienced back pain during their pregnancy were included in an intervention group (n=29), and their intensity of back pain, functional limitation and anxiety were compared with women in a control group from another antenatal clinic (n=27). The data were collected at three time points: prior to intervention, and 6 and 12 weeks after intervention. At 12 weeks after intervention, the intensity of back pain experienced by the intervention group was significantly lower than that of the control group. However, there were no statistically significant differences between the groups with respect to functional limitations and anxiety. The findings show that the pain-reducing program developed for this study was effective in reducing the intensity of back pain experienced by pregnant women. Promoting good posture and regular exercise can be recommended as a method to relieve back pain in pregnancy women. Further studies are needed to confirm the effect of the BPRP during pregnancy.

  14. Using a Non-Equivalent Groups Quasi Experimental Design to Reduce Internal Validity Threats to Claims Made by Math and Science K-12 Teacher Recruitment Programs

    NASA Astrophysics Data System (ADS)

    Moin, Laura

    2009-10-01

    The American Recovery and Reinvestment Act national policy established in 2009 calls for ``meaningful data'' that demonstrate educational improvements, including the recruitment of high-quality teachers. The scant data available and the low credibility of many K-12 math/science teacher recruitment program evaluations remain the major barriers for the identification of effective recruitment strategies. Our study presents a methodology to better evaluate the impact of recruitment programs on increasing participants' interest in teaching careers. The research capitalizes on the use of several control groups and presents a non-equivalent groups quasi-experimental evaluation design that produces program effect claims with higher internal validity than claims generated by current program evaluations. With this method that compares responses to a teaching career interest question from undergraduates all along a continuum from just attending an information session to participating (or not) in the recruitment program, we were able to compare the effect of the program in increasing participants' interest in teaching careers versus the evolution of the same interest but in the absence of the program. We were also able to make suggestions for program improvement and further research. While our findings may not apply to other K-12 math/science teacher recruitment programs, we believe that our evaluation methodology does and will contribute to conduct stronger program evaluations. In so doing, our evaluation procedure may inform recruitment program designers and policy makers.

    2011-02-01

    The purpose of this study was designed to identify the effects of heat therapy on dysmenorrhea, heat being provided using a far infrared rays heating element. The research design for the study was a non-equivalent control group quasi-experimental design. Participants were 22 students for the experimental group, and 26 students for the control group. Data were analyzed using SAS WIN 9.1 program. The experimental group had significantly lower mean scores for menstrual pain, dysmenorrhea, and blood pressure than those in the control group. However, no significant differences were found between two groups for pulse, respiration, and temperature. These findings show that thermotherapy was effective for reduction of menstrual pain, dysmenorrhea, and B/P. Therefore, this therapy could be used as a nursing intervention for students with dysmenorrhea.

  17. Design and simulation of optoelectronic complementary dual neural elements for realizing a family of normalized vector 'equivalence-nonequivalence' operations

    Krasilenko, Vladimir G.; Nikolsky, Aleksandr I.; Lazarev, Alexander A.; Magas, Taras E.

    2010-04-01

    Equivalence models (EM) advantages of neural networks (NN) are shown in paper. EMs are based on vectormatrix procedures with basic operations of continuous neurologic: normalized vector operations "equivalence", "nonequivalence", "autoequivalence", "autononequivalence". The capacity of NN on the basis of EM and of its modifications, including auto-and heteroassociative memories for 2D images, exceeds in several times quantity of neurons. Such neuroparadigms are very perspective for processing, recognition, storing large size and strongly correlated images. A family of "normalized equivalence-nonequivalence" neuro-fuzzy logic operations on the based of generalized operations fuzzy-negation, t-norm and s-norm is elaborated. A biologically motivated concept and time pulse encoding principles of continuous logic photocurrent reflexions and sample-storage devices with pulse-width photoconverters have allowed us to design generalized structures for realization of the family of normalized linear vector operations "equivalence"-"nonequivalence". Simulation results show, that processing time in such circuits does not exceed units of micro seconds. Circuits are simple, have low supply voltage (1-3 V), low power consumption (milliwatts), low levels of input signals (microwatts), integrated construction, satisfy the problem of interconnections and cascading.

  19. Statistical power for the comparative regression discontinuity design with a nonequivalent comparison group.

    PubMed

    Tang, Yang; Cook, Thomas D; Kisbu-Sakarya, Yasemin

    2018-03-01

    In the "sharp" regression discontinuity design (RD), all units scoring on one side of a designated score on an assignment variable receive treatment, whereas those scoring on the other side become controls. Thus the continuous assignment variable and binary treatment indicator are measured on the same scale. Because each must be in the impact model, the resulting multi-collinearity reduces the efficiency of the RD design. However, untreated comparison data can be added along the assignment variable, and a comparative regression discontinuity design (CRD) is then created. When the untreated data come from a non-equivalent comparison group, we call this CRD-CG. Assuming linear functional forms, we show that power in CRD-CG is (a) greater than in basic RD; (b) less sensitive to the location of the cutoff and the distribution of the assignment variable; and that (c) fewer treated units are needed in the basic RD component within the CRD-CG so that savings can result from having fewer treated cases. The theory we develop is used to make numerical predictions about the efficiency of basic RD and CRD-CG relative to each other and to a randomized control trial. Data from the National Head Start Impact study are used to test these predictions. The obtained estimates are closer to the predicted parameters for CRD-CG than for basic RD and are generally quite close to the parameter predictions, supporting the emerging argument that CRD should be the design of choice in many applications for which basic RD is now used.

    2011-04-01

    This study examined the effects of spinal health educational programs. A nonequivalent control-group pretest-posttest design was used. Participants were 88 fifth-grade elementary schoolchildren. Three groups were compared: a Web-based program group, a traditional face-to-face program group, and a control group. In both intervention groups, the changes for spinal health knowledge and self-efficacy were significantly higher than those of the control group. However, the changes of spinal health practices were not significantly different. A Web-based spinal health education program is a convenient and flexible health educational approach that was as effective in this study as traditional face-to-face instruction. © 2011, Wiley Periodicals, Inc.

    The purpose of this study was to measure the effects of a breast feeding promotion program for working women on breast feeding continuation, mother-infant attachment, and maternal sensitivity. The design of this study is nonequivalent control group design with repeated measures. There were significant differences in breast feeding continuation between two groups at each time point except 2 days and 1 week after delivery. The scores of mother-infant attachment and maternal sensitivity of experimental group were higher than those of the control group, but there were no significant differences between two groups. Although some modifications in contents and administration will be required to increase the effectiveness of the program, breast feeding promotion program for working women can be an effective nursing intervention which can facilitate breast feeding continuation and mother-infant relationships.

  7. Personality Trait Differences Between Young and Middle-Aged Adults: Measurement Artifacts or Actual Trends?

    Nye, Christopher D; Allemand, Mathias; Gosling, Samuel D; Potter, Jeff; Roberts, Brent W

    2016-08-01

    A growing body of research demonstrates that older individuals tend to score differently on personality measures than younger adults. However, recent research using item response theory (IRT) has questioned these findings, suggesting that apparent age differences in personality traits merely reflect artifacts of the response process rather than true differences in the latent constructs. Conversely, other studies have found the opposite-age differences appear to be true differences rather than response artifacts. Given these contradictory findings, the goal of the present study was to examine the measurement equivalence of personality ratings drawn from large groups of young and middle-aged adults (a) to examine whether age differences in personality traits could be completely explained by measurement nonequivalence and (b) to illustrate the comparability of IRT and confirmatory factor analysis approaches to testing equivalence in this context. Self-ratings of personality traits were analyzed in two groups of Internet respondents aged 20 and 50 (n = 15,726 in each age group). Measurement nonequivalence across these groups was negligible. The effect sizes of the mean differences due to nonequivalence ranged from -.16 to .15. Results indicate that personality trait differences across age groups reflect actual differences rather than merely response artifacts. © 2015 Wiley Periodicals, Inc.

    2017-09-01

    Older adults living with Alzheimer's disease (AD) experience more of the types of accidents and injuries prevalent among older adults. Relatively few studies specifically on safety risks have included older adults of color and tested interventions. This pilot study tested the feasibility and evaluability of educating Hispanic and African American caregivers of patients living with AD about reducing safety risks in their homes. This outpatient memory clinic-based intervention study included a pre-/post-test survey design with two nonequivalent groups and predominately serves Hispanic and African Americans. Of 60 eligible caregivers, 67% participated in a tailored, safety training class with an optional follow-up call. The results indicate a reduction in some safety risks compared to baseline and/or a no intervention group, respectively, including leaving patients at home alone part-time (p < .01 and p < .01), getting lost (p < .05 and p < .05), going outdoors alone less often (p < .05 and p < .01), and giving themselves medicine (p < .05 and p < .01). At post-test, 47 clinically significant instances occurred, in which caregivers who participated in the intervention self-reported patients living with AD to be 'completely safe' in one or more of the safety risk items compared to 8 instances among those who did not. This pilot pre/post design with non-equivalent groups study needs refinement in a future randomized control trial. Despite limitations, this pilot study demonstrates the first feasible and evaluable intervention with both statistically and clinically significant results that suggest potential for reducing safety risks among at-risk minority patients living with AD in future research.

  10. Selecting and Improving Quasi-Experimental Designs in Effectiveness and Implementation Research.

    2018-04-01

    Interventional researchers face many design challenges when assessing intervention implementation in real-world settings. Intervention implementation requires holding fast on internal validity needs while incorporating external validity considerations (such as uptake by diverse subpopulations, acceptability, cost, and sustainability). Quasi-experimental designs (QEDs) are increasingly employed to achieve a balance between internal and external validity. Although these designs are often referred to and summarized in terms of logistical benefits, there is still uncertainty about (a) selecting from among various QEDs and (b) developing strategies to strengthen the internal and external validity of QEDs. We focus here on commonly used QEDs (prepost designs with nonequivalent control groups, interrupted time series, and stepped-wedge designs) and discuss several variants that maximize internal and external validity at the design, execution and implementation, and analysis stages.

    This study analyzed the effects of a school-based mind subtraction meditation program on depression, social anxiety, aggression, and salivary cortisol levels of 42 elementary school children in South Korea. The research design was a nonequivalent group comparison with pretest and post-test. The experimental group was given 8weeks of the meditation program. The results showed social anxiety, aggression, and salivary cortisol levels were significantly lowered in the experimental group. This demonstrated that the school-based mind subtraction meditation program could be effective in improving psychosocial and behavioral aspects of mental health in elementary school children.

    The purpose of this study was to evaluate the effects on immigrant couples' communication, intimacy, conflict and quality of life when using foot massage. The research design consisted of pre-and-post test consecutive experimental design through a nonequivalent control group. Data were collected July 6, 2009 to February 27, 2010. The 36 couples were divided into two groups, experimental and control with 18 couples in each group. Foot massage was applied twice a week for 6 weeks by the couples in the experimental group. There were statistically significant increases in communication (p=.011), intimacy (p<.001), quality of life (p=.017) between the couples in the experimental group compared to the control group. There was also a statistically significant decrease in conflict (p=.003) between the couples in the experimental group compared to the control group. Foot massage can be applied as a nursing intervention for improvement of marital relationship in immigrant couples.

    Built environments in rural settings may provide greater challenges than those in urban settings due to physical characteristics inherent to low-density population areas. Multiuse recreational trails, such as those that repurpose abandoned railroad lines, may provide a physical activity resource that is well suited to rural areas. However, the direct impact of trail availability on physical activity behavior is not generally known because it is unclear whether activity reported in most trail research represents increases in physical activity or displacement of activity in individuals who previously exercised in other locations. This research, initiated by a group of students in a graduate seminar, represents to our knowledge, the first instance in which PA was assessed prior to the availability of an entirely new rails-to-trails facility. The research was implemented using a nonequivalent dependent variable design to counter the lack of a control group; the nonequivalent dependent variable chosen was weekly servings of fruit and vegetables. Participants responding to intercept interviews classified days of activity during the prior week as mild, moderate or vigorous. Baseline results for 244 participants suggested generally low levels of activity prior to trail availability; number of reported days of activity decreased with described intensity. We also discuss several issues encountered in planning and implementing this group project including those related to data collection, variable levels of commitment among student members, and inconsistent project management, and offer potential solutions to these concerns.

    This study was conducted to develop a self-management program using goal setting for patients after a stroke. The program was based on a theory-based Goal setting and Action Planning framework (G-AP), and the effectiveness of the program was examined. A non-equivalent control group pretest-posttest design was used. The experimental group (n=30) received the self-management program using goal setting based on the G-AP over 7 weeks. The education was delivered individually with a specifically designed stroke workbook. The control group (n=30) received only patient information leaflets about stroke. There were significant differences between the two groups. Stroke knowledge, self-efficacy, and health behavior compliance were significantly higher (all p<.001), and hospital anxiety (p<.001) and depression (p<.001) were significantly lower in the experimental group compared to the control group. This self-management program using goal setting based on a G-AP was found to be useful and beneficial for patients in stroke rehabilitation settings.

    The purpose of this study was to address the need for effective educational interventions to promote students' clinical decision making (CDM) within clinical practice environments. Researchers used a quasi-experimental, non-equivalent groups, posttest-only design to assess differences in CDM ability between intervention group students who participated in analogy-guided learning activities and control group students who participated in traditional activities. For the intervention, analogy-guided learning activities were incorporated into weekly group discussions, reflective journal writing, and questioning with clinical faculty. The researcher-designed Assessment of Clinical Decision Making Rubric was used to assess indicators of CDM ability in all students' reflective journal entries. Results indicated that the intervention group demonstrated significantly higher levels of CDM ability in their journals compared with the control group (ES(sm) = 0.52). Recommendations provide nurse educators with strategies to maximize students' development of CDM ability, better preparing students for the demands they face when they enter the profession.

    Examining interpersonal (physician-patient) communication strategies for promoting walking exercise to patients with type 2 diabetes assigned to primary care clinics, the study evaluated two message design variables--frame and presentation mode--as influencers of communication and adoption success. The single-site, four-week, prospective intervention study followed a 2×3 factorial, non-equivalent comparison group quasi-experimental design. Results showed frame was significantly related to steps walked; however, when including patient activation as an interaction, frame was non-significant. The model including patient activation interactions, however, detected significant mode effects on behavior. Results provide evidence that statistics are most effectively used with activated patients.

    The purpose of this study was to develop an environmental education program using newspaper articles in education (NIE) and to evaluate changes in concern and practice for environmental protection after NIE. The design was a nonequivalent control group pretest-posttest design. The participants were university students in nursing, of which 31 were assigned to the experimental group and 43 to the control group. The education was carried out for 2 hr, once a week for 7 weeks. Data were analyzed with SPSS WIN 14 program, and included chi2 test, independent t-test, and repeated measure ANOVA. NIE showed significant differences in the changes of attitude toward environment (F=4.461, p=.036). Findings suggest that this NIE in environmental education was effective in changing students' attitudes toward the environment. Therefore this NIE is recommended for inclusion in education for university students in nursing.

    The idea of action immediate propagation has been in physicists' mind from the beginning, until Faraday raised the idea of delayed propagation. Using this idea and the delayed theory of fields, we face consequences which can be interesting for anyone who has learned physics. We can mention non-equivalency between stationary frames and moving frames, dependency of field to medium, different velocity barriers for different mediums and non-equivalency of inertial reference frames are among these consequences. By designing an experiment we can challenge this theory and its consequences. All of these sections processed in the article titled ''The delayed theory of fields''.

    The current study sought to evaluate the suicide prevention gatekeeper training program QPR (Question, Persuade, and Refer) among school personnel using a non-equivalent control group design. Substantial gains were demonstrated from pre- to post-test for attitudes, knowledge, and beliefs regarding suicide and suicide prevention. Exploratory analyses revealed the possible moderating effects of age, professional role, prior training, and recent contact with suicidal youth on QPR participants' general knowledge, questioning, attitudes toward suicide and suicide prevention, QPR quiz scores, and self-efficacy. The need for replication using a more rigorous experimental design in the context of strong community collaboration is discussed.

    Emerging from Bandura's Social Learning Theory, this study of in-service elementary school teachers examined the effects of sustained Professional Learning Communities (PLCs) on self-efficacy in science teaching. Based on mixed research methods, and a non-equivalent control group experimental design, the investigation explored changes in personal self-efficacy and outcome expectancy among teachers engaged in PLCs that featured Demonstration Laboratories, Lesson Study, and annual Summer Institutes. Significant changes favoring the experimental group were found on all quantitative measures of self-efficacy. Structured clinical interviews revealed that observed changes were largely attributable to a wide range of direct (mastery) and vicarious experiences, as well as emotional reinforcement and social persuasion.

    This study was designed to examine the effect of asthma management education program applied to allergic asthma patients receiving immunotherapy due to house dust mite on their stress and compliance with health care regimens. A quasi experimental design with non-equivalent control group and non-synchronized design was used. The subjects of this study were 61 patients who were receiving immunotherapy at intervals of a week after their symptoms were diagnosed as house dust mite allergic asthma at the pulmonary department of a university hospital in Seoul. They were divided into an experimental group of 29 patients who received asthma management education and a control group of 32 patients. The asthma management education program was composed of group education (once) and reinforcement education (three times) with environmental therapy and immunotherapy to house dust mite. Stress significantly decreased in the experimental group compared to that in the control group. Compliance with health care regimens significantly increased in the experimental group compared to that in the control group. The results suggested that the asthma management education program is effective for the management of stress and the improvement of compliance in patients with allergic asthma to house dust mite.

    2006-10-01

    Published and unpublished data from nine studies on juvenile sexual offender treatment effectiveness were summarized by meta-analysis (N=2986, 2604 known male). Recidivism rates for sexual, non-sexual violent, non-sexual non-violent crimes, and unspecified non-sexual were as follows: 12.53%, 24.73%, 28.51%, and 20.40%, respectively, based on an average 59-month follow-up period. Four included studies contained a control group (n=2288) and five studies included a comparison treatment group (n=698). An average weighted effect size of 0.43 (CI=0.33-0.55) was obtained, indicating a statistically significant effect of treatment on sexual recidivism. However, individual study characteristics (e.g., handling of dropouts and non-equivalent follow-up periods between treatment groups) suggest that results should be interpreted with caution. A comparison of odds ratios by quality of study design indicated that higher quality designs yielded better effect sizes, though the difference between groups was not significant.

    Objective Analyses of individual differences in change may be unintentionally biased when versions of a neuropsychological test used at different follow-ups are not of equivalent difficulty. This study’s objective was to compare mean, linear, and equipercentile equating methods and demonstrate their utility in longitudinal research. Study Design and Setting The Advanced Cognitive Training for Independent and Vital Elderly (ACTIVE, N=1,401) study is a longitudinal randomized trial of cognitive training. The Alzheimer’s Disease Neuroimaging Initiative (ADNI, n=819) is an observational cohort study. Nonequivalent alternate versions of the Auditory Verbal Learning Test (AVLT) were administered in both studies. Results Using visual displays, raw and mean-equated AVLT scores in both studies showed obvious nonlinear trajectories in reference groups that should show minimal change, poor equivalence over time (ps≤0.001), and raw scores demonstrated poor fits in models of within-person change (RMSEAs>0.12). Linear and equipercentile equating produced more similar means in reference groups (ps≥0.09) and performed better in growth models (RMSEAs<0.05). Conclusion Equipercentile equating is the preferred equating method because it accommodates tests more difficult than a reference test at different percentiles of performance and performs well in models of within-person trajectory. The method has broad applications in both clinical and research settings to enhance the ability to use nonequivalent test forms. PMID:22540849

    To assess the effects of yogic exercise on nonspecific neck pain in university students. This study is a pretest-posttest design with a non-equivalent control group. Thirty-eight university students were selected by convenience sampling, with 18 assigned to an exercise group and 20 assigned to a control group. The yoga group participated in one-hour sessions of yogic exercise two days a week for eight weeks. The exercise comprised eight stages: relaxation, flexion of neck, extension of neck, right lateral flexion of neck, left lateral flexion of neck, right rotation of neck, left rotation of neck, and relaxation. Neck pain intensity was measured using a 100 mm visual analogue scale. The yoga group showed significantly decreased neck pain scores compared with those of the control group. These findings indicate that yogic exercises could reduce neck pain in university students. Copyright © 2017 Elsevier Ltd. All rights reserved.

    A film emphasizing the importance of tachypnea as an early manifestation of congenital heart disease was shown to physicians and nurses at 27 hospitals as part of their regular continuing medical education activities. To evaluate the effects of the program, investigators developed a pretest-posttest design which included a nonequivalent control group. Pretest and posttest data were obtained through chart audit of referrals from subjects in experimental and control groups. Dependent variables used to test the hypothesis included the age at which infants were referred and the age at which tachypnea was noted. Analysis of the data yielded significant gain scores for the experimental group, while changes in the control group were not significant. The findings indicate that a need-oriented educational program can have a measurable impact on improving the quality of patient care.

    Aerosol therapy, a treatment for children with disorders of the respiratory system, often causes distress, especially in young children. Distress during aerosol therapy can decrease the effectiveness of the treatment. This study aimed to determine the effect of audiovisual distraction on distress levels and oxygenation status (measured by oxygen saturation and respiratory frequency) in children who receive aerosol therapy for disorders of the respiratory system. A quasi-experimental design was employed, specifically a non-equivalent control group, pre-test-post-test design. The study sample consisted of 38 children who were divided into 2 groups (control and intervention), each group consisting of 19 children. The results of this study showed that there were significant differences in distress scores between the control group and the intervention group (p = .0001). There were also significant differences in the mean value changes in oxygenation status before and after intervention between the control and intervention groups. These findings could be used to prevent distress and increase oxygenation status in children who receive aerosol therapy.

    The purpose of this study was to develop a multidimensional suicide prevention program for Korean elders by utilizing a community network and to evaluate its effect. A non-equivalent control group pretest-posttest design was used. The subjects were recruited from two different elderly institutions located in D city and K province, Korea. Nineteen subjects in the control group received no intervention and 20 subjects in the experimental group received a multidimensional suicide prevention program. There were more significant decreases in depression, suicide ideation, and increases in life satisfaction in the experimental group compared to the control group. According to the above results, the multidimensional suicide prevention program for Korean elders decreased stressful events like depression, and suicide ideation and increased life satisfaction through the community network. These findings suggest that this program can be used as an efficient intervention for elders in a critical situation.

    The purpose of this study was to examine the effects of Kangaroo Care(KC) on anxiety, maternal role confidence, and maternal infant attachment of mothers who delivered preterm infants. The research design was a nonequivalent control group pretest-posttest. Data was collected from September 1. 2006 to June 20. 2007. The participants were 22 mothers in the experimental group and 21 in the control group. KC was applied three times per day, for a total of ten times in 4 days to the experimental group. The degree of anxiety was statistically significantly different between the two groups but maternal role confidence and maternal infant attachment was statistically insignificant. This data suggests that KC was effective for mothers anxiety relief but it was not effective for maternal role confidence and maternal infant attachment of mothers. The implications for nursing practice and directions for future research need to be discussed.

    This study was designed to examine the effects of a bereavement intervention program on levels of depression and life satisfaction in middle aged widows in Korea. A quasi-experimental design with non-equivalent control-group pretest-posttest was used. The subjects (control group, n = 10; intervention group, n = 17) were bereaved less than 6 months in G City and J Province, Korea. The bereavement intervention program consisted of Dan-jeon breathing, self-help group activities and a health examination. The experimental group attended 10 sessions of a bereavement intervention program. The control group had a health examination without the intervention program. For both groups, the level of depression and life satisfaction levels were measured before and after the experiment. The decrement of depression level in the experimental group was significantly greater than in the control group (p<.001). The increment in life satisfaction in the experimental group was significantly greater than in the control group (p<.001). The results suggested that the bereavement intervention program was effective in decreasing level of depression and in increasing the life satisfaction of widows. Accordingly, a bereavement intervention program can be applied as an intervention to help widows.

    This study was done to evaluate the Military Mental Health Promotion Program. The program was an email based cognitive behavioral intervention. The research design was a quasi-experimental study with a non-equivalent control group pretest-posttest design. Participants were 32 soldiers who agreed to participate in the program. Data were collected at three different times from January 2012 to March 2012; pre-test, post-test, and a one-month follow-up test. The data were statistically analyzed using SPSS 18.0. The effectiveness of the program was tested by repeated measures ANOVA. The first hypothesis that the level of depression in the experimental group who participated in the program would decrease compared to the control group was not supported in that the difference in group-time interaction was not statistically significant (F=2.19, p=.121). The second and third hypothesis related to anxiety and self-esteem were supported in group-time interaction, respectively (F=7.41, p=.001, F=11.67, p<.001). Results indicate that the program is effective in improving soldiers' mental health status in areas of anxiety and self-esteem.

    This study was designed to evaluate the effects of an individual breast-feeding promotion program to address breast-feeding knowledge, attitude, method and rate of practice for married immigrant women. A non-equivalent control group quasi-experimental design was used (experimental group=16, control group=17). The intervention consisted of 3 phases: (1) Within 2 hours of delivery - individual breast-feeding training through video/verbal/practical training education and demonstration (2) After 1~2 days - group training using video, model doll, and breast models (3) After 7 days - family visit, counseling, retraining and reinforcement training. The data were analyzed using non-parametric tests with the SPSS program. Married immigrant women who participated in the individual breast-feeding program scored high in knowledge, attitude, method and rate of practice compared to the control group. The results indicate that the individual breast-feeding program is very effective in increasing breast-feeding knowledge, attitude, method and rate of practicing breast feeding for married immigrant women. So, nurses are encouraged to aggressively utilize individual breast-feeding programs to help married immigrant women, who are exposed to vulnerability due to various situations.

    The purpose of this study was to determine effects of an empowerment education program (EEP) on internet games addiction, empowerment, and stress in middle school students. The EEP used in this study was based on the Freire's Empowerment Education Model. The research design of this study was a non-equivalent control group pretest-posttest design for 48 middle school students, who were conveniently assigned to an experimental group or a control group. The data were collected from May 29 to June 19, 2005. Data were analyzed using SPSS/PC program with frequencies, X(2)-test, Fisher exact test, t-test, mean, standard deviation and ANCOVA. 1) The first hypothesis that, "the experimental group would have higher empowerment scores than the control group." was supported. 2) The second hypothesis that, "the experimental group would have lower internet games addiction scores than the control group." was supported. 3) The third hypothesis that, "the experimental group would have lower stress scores than the control group." was supported. We suggest, therefore, that the EEP should be used with adolescent to help them control their stress, internet games addiction and to increase their empowerment.

    This study was conducted to verify the effects of an education program of restraints use on nurses' knowledge, attitude and nursing performance related to restraints use. A quasi experimental study with a pre and post non-equivalent design was used. The subjects were nurses who met the selection criteria and worked in intensive care units of two university hospitals located at K-city, Gyeongbuk. Twenty nurses in A hospital were designated as the experimental group and 20 nurses in B hospital as the control group. The first hypothesis which assumed that the experimental group would have higher scores of knowledge than the control group was supported(F=62.66, p=0.000). The second hypothesis which assumed that the experimental group would have lower scores of attitude toward using restraints than the control group was supported(F=23.77, p=0.000). The third hypothesis which assumed that the experimental group would have higher scores of nursing performance than the control group was supported(F=3.28, p=0.032). An education program for nurses' on the use of restraints needs to be introduced to decrease inappropriate use of restraints.

    This study examined risk factor outcomes among patients who attended cardiac rehabilitation sessions, those who received traditional care, and those who attended Leap for Life workshops. A non-equivalent, three-group design was used in this observational study. Baseline and 12-month measurements were collected for 217 participants. Analysis of covariance was performed to determine differences between groups on outcome variables. The only significant finding was in participants with an initial high-density lipoprotein value of less than 40. High-density lipoprotein levels increased more in the cardiac rehabilitation group than in the traditional care group (30.54 to 37.48 versus 30.17 to 33.67 [F= 4.577, p = .035]). Based on these findings, a strong case can be made for the transition to more individually intense and focused risk factor modification strategies for patients in cardiac rehabilitation programs.

    A nonequivalent, control group, pretest-posttest design was used to investigate student achievement in secondary chemistry. This study investigated the effect of process oriented guided inquiry learning (POGIL) in high school chemistry to reduce alternate conceptions related to the particulate nature of matter versus traditional lecture pedagogy. Data were collected from chemistry students in four large high schools and analyzed using ANCOVA. The results show that POGIL pedagogy, as opposed to traditional lecture pedagogy, resulted in fewer alternate conceptions related to the particulate nature of matter. Male and female students in the POGIL group posted better posttest scores than their traditional group peers. African-American and Hispanic students in the POGIL group exhibited achievement gains consistent with Caucasian and Asian students. Further studies are needed to determine the value of POGIL to address achievement gap concerns in chemistry.

    The objectives of this study are to assess undergraduate awareness of cancer risk factors, prevention strategies, and warning signs and to evaluate whether an educational intervention increases cancer awareness. This study adopts a nonequivalent control group pretest-posttest design. Of the 386 students who completed the pretest, only 35-39 % identified low fruit and vegetable intake, being overweight, and physical inactivity as cancer risk factors, and <30 % recognized persistent changes in bowel or bladder habits and persistent cough or hoarseness as cancer warning signs. After the educational intervention, the analysis of variance of changes from baseline (the pretest score) for all four experimental groups were all significantly higher than those of the two control groups (p ≤.001), except for the change of the retention test score from the pretest score for experimental group 3. This study highlights the need to improve undergraduates' cancer awareness and the effectiveness of educational intervention.

    Case-based learning (CBL) is a teaching strategy which promotes clinical problem-solving ability. This research was performed to investigate the effects of CBL on problem-solving ability of graduate nurses. This research was a quasi-experimental design using pre-test, intervention, and post-test with a non-synchronized, non-equivalent control group. The study population was composed of 190 new graduate nurses from university hospital A in Korea. Results of the research indicate that there was a statistically significant difference in objective problem-solving ability scores of CBL group demonstrating higher scores. Subjective problem-solving ability was also significantly higher in CBL group than in the lecture-based group. These results may suggest that CBL is a beneficial and effective instructional method of training graduate nurses to improve their clinical problem-solving ability. Copyright © 2013 Elsevier Ltd.

    This study examined the effects of a clown-nurse educational intervention on children undergoing day surgery for strabismus. This was a quasi-experimental study, using a nonequivalent control group, non-synchronized design. Fifty preschool children and their parents were invited to participate. The children in the intervention group (n=23) received clown therapy and subsequently reported significantly lower states of physiological anxiety, which was evidenced by systolic blood pressure, standardized behavioral anxiety tests, and post-surgery pain, than the control group (n=27). In addition, the parents in the experimental group showed a low state of physiological anxiety, evidenced by systolic blood pressure, pulse rates, standardized behavioral anxiety tests, and state-trait anxiety. The use of preoperative clown intervention may alleviate postoperative problems, not only for children, but also for their parents. Copyright © 2015 Elsevier Inc. All rights reserved.

    To compare learning outcomes of postpartum hemorrhage simulation training based on either instructional design guidelines or best practice. A pretest-post-test non-equivalent groups study was conducted among obstetrics and gynecology residents in Recife, Brazil, from June 8 to August 30, 2013. The instructional design group included 13 teams, whereas the best practice group included seven teams. A standardized task checklist was used for scenario analysis and the proportion of correctly executed tasks compared (post-test minus pretest). The instructional design group scored higher than the best practice group for total number of tasks completed (median difference 0.46 vs 0.17; P<0.001; effect size [r]=0.72). Similar results were observed for communication (median difference 0.56 vs 0.22; P=0.004; r=0.58), laboratory evaluation (median difference 0.83 vs 0.00; P<0.001; r=0.76), and mechanical management (median difference 0.25 vs -0.15; P=0.048; r=0.39). Speed of learning was also increased. The median differences were 0.20 for the instructional design group compared with 0.05 for the best practice group at 60 seconds (P=0.015; r=0.49), and 0.49 versus 0.26 (P=0.001; r=0.65) at 360 seconds. The use of simulation training for postpartum hemorrhage that was based on instructional design guidelines yielded better learning outcomes than did training based on best practice. © 2016 International Federation of Gynecology and Obstetrics.

    The objective of this study was to identify the effects of a skin rehabilitation nursing program (SRNP) on skin status, depression, and burn-specific health in Korean burn survivors. A pretest-posttest design with a nonequivalent control group was used to examine the effects of SRNP for 3 months in a group of 26 burn survivors. The SRNP group of 13 burn survivors received massage therapy 30 minutes three times a week for 3 months compared to a control group of 13 burn survivors receiving typical care. The SRNP group showed no significant changes in the burn scar, subjective skin status, depression, or burn-specific health. Burn survivors receiving SRNP had reduced burn scar depth after the intervention compared to the control group. The findings of this study demonstrate that SRNP for burn survivors may improve burn scars, and findings suggest that future studies with a larger sample should be conducted using SRNP as an intervention for burn survivors.

    Spatially resolved luminescence spectra from U(VI) co-precipitated at the (101¯4) growth surface of synthetic calcite single crystals confirm heterogeneous incorporation corresponding to the distribution of structurally non-equivalent steps composing the vicinal surfaces of spiral growth hillocks. Spectral structure from U(VI) luminescence at the "-" vicinal regions and featureless, weak luminescence at the "+" vicinal regions are consistent with previously reported observations of enrichment at the former sites during calcite growth. Luminescence spectra differ between the non-equivalent regions of the crystal, with the spectral features from the "-" vicinal region corresponding to those observed in bulk calcite samples. Subtle spectral shifts are observed from U(VI) co-precipitated with microcrystalline calcite synthesized by a different method, and all of the U(VI)-calcite sample spectra differ significantly from that of U(VI) co-precipitated with aragonite. The step-selective incorporation of U(VI) can be explained by a proposed model in which the allowed orientation for adsorption of the dominant calcium uranyl triscarbonate species is controlled by the atomic arrangement at step edges. Differences in the tilt angles of carbonate groups between non-equivalent growth steps favor adsorption of the calcium uranyl triscarbonate species at "-" steps, as observed in experiments.

    This research aimed to develop and test a mentored obesity management program guiding physical exercise, improving eating habits, and promoting self-esteem among elementary school learners. A nonequivalent control group pretest-posttest design was used. Thirty learners were recruited through convenience sampling from two elementary schools, then evenly assigned to the experimental and control groups. Six nursing students were mentored, receiving 16h of mentorship training. A 10-week mentored obesity management program promoting physical exercise and proper nutrition was developed and provided. The two groups' pretest and posttest body mass index and self-esteem differences were statistically significant. Most participants were satisfied with the program, endorsing its provision in the regular school curriculum. A mentored obesity management program for elementary school learners would effectively manage weight and improve self-esteem. Programs purportedly curtailing childhood obesity should be expanded, and school policies regulated to enable implementation. Copyright © 2016 Elsevier Inc. All rights reserved.

    The purpose of this study was to investigate the effects of video-based peer review on communication skills and learning motivation among nursing students. A non-equivalent control with pretest-posttest design was used. The participants were 47 sophomore nursing students taking a fundamentals of nursing course at a nursing college in Korea. Communication with a standardized patient was videotaped for evaluation. The intervention group used peer reviews to evaluate the videotaped performance; a small group of four students watched the videotape of each student and then provided feedback. The control group assessed themselves alone after watching their own videos. Communication skills and learning motivation were measured. The intervention group showed significantly higher communication skills and learning motivation after the intervention than did the control group. The findings suggest that peer review is an effective learning method for nursing students to improve their communication skills and increase their motivation to learn.

    Research Methods Tutor (RMT) is a dialogue-based intelligent tutoring system for use in conjunction with undergraduate psychology research methods courses. RMT includes five topics that correspond to the curriculum of introductory research methods courses: ethics, variables, reliability, validity, and experimental design. We evaluated the effectiveness of the RMT system in the classroom using a nonequivalent control group design. Students in three classes (n = 83) used RMT, and students in two classes (n = 53) did not use RMT. Results indicated that the use of RMT yieldedstrong learning gains of 0.75 standard deviations above classroom instruction alone. Further, the dialogue-based tutoring condition of the system resulted in higher gains than did the textbook-style condition (CAI version) of the system. Future directions for RMT include the addition of new topics and tutoring elements.

    An applied ergonomics intervention program (AEIP) was conducted with male employees who work in the pressing and storage sections of a metal auto parts factory in eastern Thailand. The objective of this study was to reduce worker muscular discomfort at the low back. The study design was a participatory research approach, with quasi-experimental pretest-posttest, and with a non-equivalent control group. Thirty-five persons participated in the AEIP (AEIP group) and 17 persons did not (non-AEIP group). The AEIP was composed of three major categories: (1) top management support; (2) equipment designed for workstations and manual material handling; and (3) administrative intervention, training, and health education. Muscle activity was measured by surface electromyography of the left and right erector spinae, and multifidus muscles; and evaluated by multivariate test for dependent samples (paired observation) and for independent samples. After the AEIP, the low back muscular loads of the AEIP group was significantly reduced, while those of the non-AEIP group were not. Comparison of the means of percentage maximum voluntary contractions (% MVC) of low back muscular activity between the AEIP group and non-AEIP group indicated that the AEIP group had significantly reduced low back muscular load, with a 95% confidence level (p-value < 0.05).

    Despite its widespread support, the most effective simulation-based debriefing method has little evidence to support its efficacy. In this study, we compared the effect of peer-led and instructor-led debriefing among nursing students. The study was conducted with a non-equivalent control group using a pretest-post-test design. A convenience sample of third-year nursing students was used for the study, where 65 students enrolled in a 2-week clinical placement rotation were randomly assigned to the instructor-led group or peer-led group. The quality of cardiopulmonary resuscitation skills, satisfaction with simulation, and quality of debriefing in the peer-led group were compared to those in the instructor-led group. Group differences at each testing interval were analyzed using independent t-test. Nursing students in the instructor-led debriefing group showed better subsequent cardiopulmonary resuscitation performance, more satisfaction with simulation experience, and higher debriefing scores compared to the peer-led group. From our study, instructor-led debriefing is an effective method in improving skills performance, inducing favorable satisfaction, and providing better quality of debriefing among nursing students. © 2016 John Wiley & Sons Australia, Ltd.

    The aim of this study was to evaluate the effects of a smoking cessation education on endothelial function and carboxyhemoglobin levels in smokers with variant angina. A nonequivalent control group pretest-posttest design was used. Participants were 60 male smokers with variant angina admitted to one hospital: the control group (30) between September and December, 2009, and the experimental group (30) between February and May, 2010. Endothelial function, as defined by flow-mediated vasodilation (FMD) of the brachial artery, and serum carboxyhemoglobin (COHb) were determined at baseline and at 3 months after the initiation of education in both groups. Three months after the program, smoking cessation was successful in 22 of the 30 smokers in the experimental group, but only in 4 of 30 smokers in the control group (p<.001). After the education, the experimental group showed a significant increase in FMD, and a significant decreased in serum COHb compared with the control group. The findings indicate that this smoking cessation education program is effective for hospitalized smokers with variant angina.

    The purpose of this mixed-methods study was to evaluate the effects of an innovative critical care interprofessional education intervention on prelicensure nursing and medical students at a large public university. The class provided opportunities for students to (a) explore stereotypes about each respective profession, (b) examine the occurrence and effects of interprofessional conflict in high-acuity areas, and (c) explore conflict resolution techniques while learning how to perform critical care procedures as a team. A nonequivalent control group design with pretest, posttest, and focus group interviews were used. Data analyses indicated no subscales and total scores were significantly different across time or between groups. However, focus group analyses indicated that changes did occur. The findings suggest that students experience interprofessional conflict in clinical settings, yet lack the confidence and skills to effectively mitigate these behaviors. Ongoing studies to measure student empowerment and their intentions to practice collaboratively before and after graduation are recommended. [J Nurs Educ. 2016;55(12):696-700.].

Quasi-experimental design with nonequivalent comparison group and 6-month follow-up. Cooking Matters for Adults programs in CA, CO, ME, MA, MI, and OR. Participants in CM attending classes in April to July, 2016 (n = 332); comparison group (n = 336). Cooking Matters for Adults educated low-income adults to shop for and prepare healthy meals economically using hands-on meal preparation, facilitated discussion, and an interactive grocery store tour. Classes met for 2 hours, once a week for 6 weeks. Food resource management practices; FRM self-confidence (ie, in shopping for and preparing healthy foods on a budget); worrying that food might run out. Pearson's chi-square test and t tests identified measures associated with outcomes of interest and between-group differences. Repeated-measures linear mixed models with fixed and random effects were used to examine differences in outcomes between participants in CM and nonequivalent comparison group and to estimate the treatment effect of the program at 3 and 6 months after course completion. Six months after course completion, CM participants demonstrated improvements in all outcome measures of interest: Use of FRM practices improved (P = .002) as did FRM confidence (P < .001). Participants also worried less that food would run out before they had money to buy more (P = .03). This study demonstrated a positive impact of including FRM skills and confidence building in a nutrition education program, the effects of which could be seen for 6 months after participation in the program. Equipping low-income families with FRM skills allowed them to access healthier foods even during times of hardship. Copyright © 2017 Society for Nutrition Education and Behavior.

    To evaluate a systematic treatment programme developed by the researcher that targeted aspects of visual functioning affected by visual field deficits following stroke. The study design was a non-equivalent control (conventional) group pretest-posttest quasi-experimental feasibility design, using multisite data collection methods at specified stages. The study was undertaken within three acute hospital settings as outpatient follow-up sessions. Individuals who had visual field deficits three months post stroke were studied. A treatment group received routine occupational therapy and an experimental group received, in addition, a systematic treatment programme. The treatment phase of both groups lasted six weeks. The Nottingham Adjustment Scale, a measure developed specifically for visual impairment, was used as the primary outcome measure. The change in Nottingham Adjustment Scale score was compared between the experimental (n = 7) and conventional (n = 8) treatment groups using the Wilcoxon signed ranks test. The result of Z = -2.028 (P = 0.043) showed that there was a statistically significant difference between the change in Nottingham Adjustment Scale score between both groups. The introduction of the systematic treatment programme resulted in a statistically significant change in the scores of the Nottingham Adjustment Scale.

    Using a non-equivalent control group design, this report evaluated a previously studied behavioural intervention, the Stamp-in-Safety programme, which is designed to reduce the injury risk for young children on playgrounds at childcare centres by increasing the quality of adult supervision and rewarding children for safe play. In an urban, commercial childcare centre, 71 children aged 3-5 years and 15 teachers participated. Primary outcome measures were teacher verbalisations (warnings, explanations, redirects), teacher location (core, outskirt, or fringe of playground), child risk-taking behaviours (using equipment appropriately) and the number of injuries on the playground. Analyses revealed that the intervention had a modest positive effect in promoting safer teacher and child playground behaviours. This study reaffirms previous results that the Stamp-in-Safety programme is an effective method to decrease the risk of playground injuries at childcare centres.

    The purpose of this study was to identify the effects of the program to promote drinking knowledge, attitudes, and coping behavior in preschool children. A quasi-experimental with non-equivalent control group pretest-posttest design was conducted. The participants were 123 five year old children from G city. They were assigned to the experimental group (n=77) or the control group (n=46). A pretest and posttest were conducted to measure main variables. For the experimental group, the drinking prevention program was given for 6 weeks. Data were analyzed using χ²-test, t-test, and ANCOVA. After the intervention, preschool children in the experimental group reported significant differences in drinking knowledge (F=9.25, p=.003), drinking attitudes (F=19.57, p<.001), and coping behavior (F=16.38, p<.001) compared to preschool children in the control group. The results of this study indicate that a drinking prevention program for preschool children is effective in increasing drinking knowledge, attitudes, and coping behavior. This drinking prevention program is recommended as an effective intervention for preschool age children to postpone an early introduction to drinking.

    To test the hypotheses of positive changes of fathers' knowledge, attitude and involvement in supporting exclusive breastfeeding (EBF) after receiving breastfeeding education materials and counseling services. A quasi-experimental, pre-test-post-test, non-equivalent control group design was used. At baseline, 251 and 241 pregnant women and their husbands were enrolled into the intervention and control groups, respectively. The 1-year intervention targeting fathers included mass media, game show-style community events, group and individual counseling at health facilities and home visits. Compared to fathers in the control group, fathers in the intervention group had higher BF knowledge scores and higher attitude scores reflecting more positive attitudes toward early initiation of BF and 6 months EBF. Fathers in the intervention group were also more likely to report active involvement in supporting mothers to practice EBF during antenatal and postpartum periods. The community-based education model should be maintained and considered for conducting further test in wider application to mobilize fathers in supporting EBF.

    This study presents findings from a quasiexperimental, nonequivalent, group-design study with repeated measures that explored the effects of integrated trauma-informed services on the severity of substance abuse, mental health, posttraumatic stress disorder (PTSD) symptomatology among women with histories of trauma in urban, community-based substance abuse treatment. The study also explored if the model of integrated services was equally beneficial for women of various racial/ethnic groups. Participants in the study were 342 women receiving substance abuse treatment in intervention and comparison sites. Results indicated that at 6 and 12 month follow-ups, those in the trauma-informed intervention group, in contrast to the comparison group, had significantly better outcomes in drug abstinence rates in the past 30 days as well as in mental health and PTSD symptomatology. Results also showed that, overall, integrated services were beneficial for women across the different racial/ethnic groups in substance abuse treatment, although some differences appear to exist across racial/ethnic groups in improving addiction severity and mental health and PTSD symptomatology.

    This study examined the effectiveness of two approaches used in elementary schools to improve children's handwriting. Participants were 72 New York City public school students from the first and second grades. A nonequivalent pretest-posttest group design was used in which students engaged in handwriting activities using two approaches: intensive handwriting practice and visual-perceptual-motor activities. Handwriting speed, legibility, and visual-motor skills were examined after a 12-wk Handwriting Club using multivariate analysis of variance. The results showed that students in the intensive handwriting practice group demonstrated significant improvements in handwriting legibility compared with students in the visual-perceptual-motor activity group. No significant effects in handwriting speed and visual-motor skills were found between the students in intensive handwriting practice group and the students in visual-perceptual-motor activities group. The Handwriting Club model is a natural intervention that fits easily into existing school curriculums and can be an effective short-term intervention (response to intervention Tier II).

    Premarital education may help emerging adults form healthy relationships, but evaluation research is needed, particularly with community samples. We studied emerging adults in the Premarital Interpersonal Choices and Knowledge (PICK) program, using a pre- to post- and a posttest-then-retrospective-pretest design to examine change in perceived relationship skills, partner selection, relational patterns, and relationship behaviors and attitudes. Mixed models analyses showed that scores for the treatment group (n = 682) increased from pre to post on all four outcomes. Changes in scores for the nonequivalent comparison group (n = 462) were nonsignificant. In addition, significant differences between pre- and retrospective prescores demonstrated evidence for response shift bias. The results suggest that the PICK program helps participants increase their knowledge regarding the components of healthy relationship formation. © 2016 American Association for Marriage and Family Therapy.

    The purpose of this study is to investigate the effectiveness of guided-inquiry approach in science classes over existing science and technology curriculum in developing content-based science achievement, science process skills, and attitude toward science of grade level 6 students in Turkey. Non-equivalent control group quasi-experimental design was used to investigate the treatment effect. There were 162 students in the experimental group and 142 students in the control group. Both the experimental and control group students took the Achievement Test in Reproduction, Development, and Growth in Living Things (RDGLT), Science Process Skills Test, and Attitudes Toward Science Questionnaire, as pre-test and post-test. Repeated analysis of variance design was used in analyzing the data. Both the experimental and control group students were taught in RDGLT units for 22 class hours. The results indicated the positive effect of guided-inquiry approach on the Turkish students' cognitive as well as affective characteristics. The guided inquiry enhanced the experimental group students' understandings of the science concepts as well as the inquiry skills more than the control group students. Similarly, the experimental group students improved their attitudes toward science more than the control group students as a result of treatment. The guided inquiry seems a transition between traditional teaching method and student-centred activities in the Turkish schools.

    Low levels of literacy in early childhood can have lasting effects on children's educational and intellectual development. Many countries have implemented newborn literacy programs designed to teach parents pre-literacy promoting activities to share with their children. We conducted 2 quasi-experimental studies using 1) a pre-test/post-test design and 2) a non-equivalent control group design to examine the effect of newborn literacy programs on parents' self-reported literacy intentions/behaviors, values toward literacy, and parent-child interactions. Parents were recruited from 3 provinces, 2 with newborn literacy programs (intervention) and 1 without (control). Parents in the intervention group completed prenatal and postnatal (after participation in program) questionnaires. Parents in the control group completed 1 questionnaire. Questionnaires were designed to capture parents' literacy intentions (prenatal), behaviors (postnatal), values, and parent-child interactions (postnatal). A total of 98 parents were included in study one and 174 were included in study two. Parents' self-reported prenatal intentions and values were higher than their postnatal behaviors and values. Parents in the intervention group exhibited higher literacy behaviors and values and greater enjoyment reading to their children than parents in the control group, though they also reported reading to their children less frequently. Parents in the intervention group had significantly higher Positive Interactive scores than controls. Overall, we found participation in newborn literacy programs positively impacted parenting behaviors and attitudes. Lower postnatal within-group scores (intentions and values versus behaviors and values) may have been the result of participants' high expectations. Given our findings, we recommend that these programs continue.

    The objective of this study was to evaluate the impact of Chuma na Uchizi, a livelihood intervention for people living with HIV (PLHIV) in rural Eastern Province, Zambia, on food security. The intervention included cash transfers to purchase income-generating assets, access to a savings account, and life-skills training. The study employed a non-equivalent groups design to compare intervention (n = 50) and control participants (n = 51) who were receiving outpatient care from two comparable health facilities in distinct constituencies in the same geographic area. We collected data before and after implementation of the intervention. Chuma na Uchizi improved access to food. At follow-up, the intervention group reported lower food insecurity scores compared with the control group (β = -5.65; 95% CI - 10.85 --0.45). Livelihood programs for PLHIV are practical and may be a promising approach to address food insecurity and its adverse effects.

    The family of compounds CBrnCl4-n has been proven helpful in unraveling microscopic mechanisms responsible for glassy behavior. Some of the family members show translational ordered phases with minimal disorder which appears to reveal glassy features, thus deserving special attention in the search for universal glass anomalies. In this work, we studied CBrCl3 dynamics by performing extensive molecular dynamics simulations. Molecules of this compound perform reorientational discrete jumps, where the atoms exchange equivalent positions among each other revealing a cage-orientational jump motion fully comparable to the cage-rototranslational jump motion in supercooled liquids. Correlation times were calculated from rotational autocorrelation functions showing good agreement with previous reported dielectric results. From mean waiting and persistence times calculated directly from trajectory results, we are able to explain which microscopic mechanisms lead to characteristic times associated with α- and β-relaxation times measured experimentally. We found that two nonequivalent groups of molecules have a longer characteristic time than the other two nonequivalent groups, both of them belonging to the asymmetric unit of the monoclinic (C2/c) lattice.

  15. Quasi experimental designs in pharmacist intervention research.

    Krass, Ines

    2016-06-01

    Background In the field of pharmacist intervention research it is often difficult to conform to the rigorous requirements of the "true experimental" models, especially the requirement of randomization. When randomization is not feasible, a practice based researcher can choose from a range of "quasi-experimental designs" i.e., non-randomised and at time non controlled. Objective The aim of this article was to provide an overview of quasi-experimental designs, discuss their strengths and weaknesses and to investigate their application in pharmacist intervention research over the previous decade. Results In the literature quasi experimental studies may be classified into five broad categories: quasi-experimental design without control groups; quasi-experimental design that use control groups with no pre-test; quasi-experimental design that use control groups and pre-tests; interrupted time series and stepped wedge designs. Quasi-experimental study design has consistently featured in the evolution of pharmacist intervention research. The most commonly applied of all quasi experimental designs in the practice based research literature are the one group pre-post-test design and the non-equivalent control group design i.e., (untreated control group with dependent pre-tests and post-tests) and have been used to test the impact of pharmacist interventions in general medications management as well as in specific disease states. Conclusion Quasi experimental studies have a role to play as proof of concept, in the pilot phases of interventions when testing different intervention components, especially in complex interventions. They serve to develop an understanding of possible intervention effects: while in isolation they yield weak evidence of clinical efficacy, taken collectively, they help build a body of evidence in support of the value of pharmacist interventions across different practice settings and countries. However, when a traditional RCT is not feasible for logistical and/or ethical reasons researchers should endeavour to use the more robust of the quasi experimental designs.

    Reading is a multi-sensory and multi-cognitive task, and its difficulties (e.g., dyslexia) are not a unitary disorder. There are probably a variety of manifestations that relate to the actual site of impairment. A randomized, pre-test/post-test nonequivalent-groups design was conducted over 4 months with three groups aged between 6 and 8 years. One group comprised 76 participants (34 boys, 42 girls) with reading difficulties and altered sensory fusion (RD+ASF), a second group was made up of 123 students (59 boys, 64 girls) with reading difficulties but without altered sensory fusion (RD), and a third group comprised 81 participants (39 boys, 42 girls) who were young readers (RL) without reading delay, paired with the RD group on reading level. The experimental groups received intervention in the skills of control, stimulus recognition, and phonological awareness during a 4-month period. Both pre-test and post-test measures of errors in reading mechanics and reading routes (word and pseudo-word) were obtained. Poorer results in mechanics and reading routes of the RD+ASF group suggest that the effectiveness of the intervention depended on the characteristics of the groups and on the presence of sensory fusion deficits in the RD students.

    Applying 63Cu NMR technique, we observed exchange between the nonequivalent copper sites in crystalline Cu6PS5Br, known as a member of the mineral "argyrodite". Below 200 K, where the motion of the copper (I) ion is slow, we could distinguish several nonequivalent copper sites. On increasing the temperature, the chemical exchange between the nonequivalent cation sites was seen on the 63Cu NMR spectra. We could determine the activation energy for this motion to be 35 kJ mol-1 , in good agreement with the published ionic conductivity.

    To evaluate the effectiveness of feedback to medical staff in reducing inappropriate hospital days, particularly those attributable to conservative medical discharge policies. Quasi-experimental pre-test/post-test with non-equivalent control group. A publicly funded hospital in industrial belt in Barcelona (Spain), serving a predominantly urban population of 100,000. Two non-equivalent groups: control group (surgery department) and intervention group (internal medicine department). Meetings between hospital management and medical staff of the intervention group to inform clinicians of percentages and reasons for inappropriate stays in their departments. Total inappropriate hospital days and percentage attributable to physicians, measured with the Appropriateness Evaluation Protocol before, during, and after intervention. There were no relevant differences in the characteristics of the populations whose stays were reviewed during each of the periods. The total number of inappropriate stays and the percentage attributable to the doctor in the control group did not show any differences between the periods. In the intervention group, inappropriate stays attributable to the doctor decreased from 35.9% in the period to intervention to 27.7% during intervention (relative drop of 22.8%; P < 0.01), and rose to 32.7% after intervention. Differences in total inappropriate days were not significant. Providing physicians with feedback about percentage of inappropriate hospital days produced a significant reduction in the number of inappropriate stays attributable to the doctor, although the impact on overall inappropriate stays is inconclusive.

    This study was conducted to examine the changing patterns of knowledge related to disease, medication adherence, and self-management and to determine if outcomes were more favorable in the experimental group than in the comparison group through 6 months after providing a web-based self-management intervention. A non-equivalent control group quasi-experimental design was used and 65 patients with gout, 34 in experimental group and 31 in comparison group, were selected from the rheumatic clinics of two university hospitals. Data were collected four times, at baseline, at 1 month, 3 months, and 6 months after the intervention. According to the study results, the changing patterns of knowledge and self-management were more positive in the experimental group than in the control group, whereas difference in the changing pattern of medication adherence between two groups was not significant. The results indicate that the web-based self-management program has significant effect on improving knowledge and self-management for middle aged male patients with gout. However, in order to enhance medication adherence, the web-based intervention might not be sufficient and other strategies need to be added.

    A firm understanding of the preliminary assessment of a patient with neurological disorders is needed for ensuring optimal patient outcomes. The purpose of this study is to evaluate the effects of using e-learning on neurologic assessment knowledge, ability, and self-confidence among nurses. This study used a non-equivalent control group pretest-posttest design. Nurses working in the neurology and neurosurgery wards, Republic of Korea PARTICIPANTS: A convenience sample of 50 nurses was assigned to either the experimental group (n=24) or the control group (n=26). The experimental group participated in the self-directed e-learning program related to neurologic assessment, and control group underwent self-directed learning with handout. Knowledge, ability, and self-confidence were measured at pretest and posttest. There were no significant differences in knowledge (U=270, p=0.399) and self-confidence (U=241.5, p=0.171) between the two groups. Nurses in the experimental group showed higher neurologic assessment ability compared with those in the control group (U=199, p=0.028). Self-directed neurologic assessment e-learning induced improvement in the neurologic assessment ability among nurses. Self-directed e-learning can be applied for improving competencies in neurologic assessment. Copyright © 2017 Elsevier Ltd. All rights reserved.

    The purpose of this study was to verify the effect of aromatherapy massage on abdominal fat and body image in post-menopausal women. A Non-equivalent control group pre-post test Quasi-experimental design of random assignment was applied. All subjects received one hour of whole body massage as treatment by the same researcher every week for 6 weeks. Participants also massaged their own abdomen two times everyday for 5 days each week for 6 weeks. The two groups used different kinds of oil. The experimental group used 3% grapefruit oil, cypress and three other kinds of oil. The control group used grapeseed oil. Data was collected before and after the treatment using Siemens Somatom Sensation 4, a tape measure and MBSRQ. Data was analyzed by ANCOVA using the SPSS/PC+Win 12 Version. Abdominal subcutaneous fat and waist circumference in the experimental group significantly decreased after aromatherapy massage compared to the control group. Body image in the experimental group was significantly better after aromatherapy massage than in the control group. These results suggest that Aromatherapy massage could be utilized as an effective intervention to reduce abdominal subcutaneous fat, waist circumference, and to improve body image in post-menopausal women.

    The purpose of this study was to verify effects of the Empowering A Self-Efficacy (EASE) program on self-efficacy, self-management, and child attitude toward illness in children with epilepsy. This was a quasi-experimental study with a non-equivalent control group pre-post test design. Participants were 10 to 15 year old children with epilepsy (11 in the experimental group and 10 in the control group) who were registered at one hospital in S city. The experimental group received the EASE program for 3 weeks. In the first week, a group meeting lasting 570 minutes was conducted on a single day. Over the next two weeks, telephone counselling was conducted twice a week. Data were analyzed using SPSS 18.0. There was a significant difference of pre-post evaluation of the epilepsy self-management scores in the experimental group. However, differences between the experimental group and the control group for seizure self-efficacy and child attitude toward illness were not significant. This is the first study in Korea to develop and evaluate an intervention program for children with epilepsy. Further studies are needed to confirm the effects of the EASE program.

  7. Evaluation of interventions to prevent injuries: an overview

    PubMed Central

    1998-01-01

    Overview of issues involved in evaluating the effectiveness of injury interventions is presented. An intervention should be evaluated to show it prevents injuries in the target population, to identify unintended consequences, to correct problems that limit effectiveness, to justify current and future resources from funding agencies, and to guide its replication elsewhere. Problems in conducting evaluations include obtaining sufficient resources, coping with rare events, establishing reliability and validity of measurement instruments, separating effects of multiple simultaneous events, and adjusting for the time lag between an intervention and its effects. When feasible, changes in injury rates (documented by medical records) should be used. These are more convincing for demonstrating intervention effectiveness than changes in observed or reported behaviors or in knowledge and attitudes (documented by surveys). Quasiexperimental evaluation designs are often useful, such as measuring injury rates before and after an intervention in a time series design, or intervening in one of two comparable communities in a non-equivalent control group design. Evaluations using true experimental designs, in which individuals or groups are randomized to receive or not receive an intervention, are highly desirable but are often difficult due to logistical or ethical considerations. An evaluation component should be integral to the introduction of any new injury intervention. PMID:9666371

    The purpose of this study was to compare differences in the time when bowel sounds were heard and gas was passed in women who had an abdominal hysterectomy and were treated for 5 minutes (experimental group A) or 10 minutes (experimental group B) with San-Yin-Jiao (SP-6) acupressure. The design of this study was a nonequivalent control group non-synchronized post test only design. The participants included 142 women, 39 in experimental group A, 30 in experimental group B, and 73 in the control group. Data was collected using a structured questionnaire which included items on general characteristics and a self report of time when gas was passed. Differences for the three groups as to time when bowel sounds were heard and gas was passed were analyzed using ANOVA. The time when bowel sounds were heard was statistically significantly shorter in both experimental groups compared to the control group(F=10.29, p=.000). The time when gas was passed was statistically significantly shorter in experimental group B(10 min) compared to the control group(F=4.68, p=.011). It could be concluded that SP-6 acupressure of 10 minutes was effective in shortening the time until bowel sounds were heard and gas was passed for women who had had an abdominal hysterectomy. Replication of the study with a larger number of participants is necessary in order to be able to generalize the results.

    To evaluate the effect of a theory-based oral health promotion intervention in a community environment by a nondental peer educator on the oral hygiene and gingival health of independent-living Italian older adults. A quasiexperimental design with a pretest-posttest nonequivalent control group with no intervention. Ten Melbourne-based Italian social clubs participated in this evaluation. One hundred forty-four active members of the social clubs. A series of oral health seminars and four supervised brushing sessions at club premises. The intervention did not involve any direct oral health professional clinical care. Clubs were allocated to the control or intervention group. Dental plaque levels and gingival bleeding scores were determined. A series of one-way analyses of covariance were conducted using the baseline measures as covariates. Controlling for pretest scores, the experimental group was significantly more likely than the control group to have improved gingival status and self-efficacy. No significant effects were found regarding dental plaque. Within the setting of Italian social clubs, the intervention was effective at increasing self-efficacy and reducing gingival bleeding. As such, it represents a useful approach for the design of oral health interventions in older migrant adults. © 2013, Copyright the Authors Journal compilation © 2013, The American Geriatrics Society.

    This study examines the application of classical music backsound in mathematics learning. The method used is quasi experimental design nonequivalent pretest-posttest control group in elementary school students in Tasikmalaya city, Indonesia. The results showed that classical music contributed significantly to the mathematical intelligence of elementary school students. The mathematical intelligence shown is in the cognitive ability ranging from the level of knowledge to evaluation. High level mathematical intelligence is shown by students in reading and writing integers with words and numbers. The low level of mathematical intelligence exists in projecting the story into a mathematical problem. The implication of this research is the use of classical music backsound on learning mathematics should pay attention to the level of difficulty of mathematics material being studied.

    The purpose of this study was to evaluate the effects of a sex education program, which was based on the Health Belief Model, on knowledge related to sexually transmitted diseases and sexual autonomy among university students. A non-equivalent control group, pretest-posttest design was used. The four session program was delivered to 18 students during 4 weeks; the control group consisted of 23 students. The theme of the first session was "sex, gender, and sexuality: all our concern", "dangerous sex" for the second session, "safe sex" for the third session, and "right sex for you and me" for the fourth session. At follow-up, the knowledge related to sexually transmitted diseases and sexual autonomy were significantly greater in the intervention group than in the control group. A sex education program with several sessions within the theoretical frame of HBM was effective to improve knowledge related to sexually transmitted diseases and sexual autonomy. The results suggest the potential of a systematic sexual education program to teach healthy sex and to extend the program for other various populations.

    Most Korean women who experience menstrual pain have reported taking pain medicine and making use of complementary alternative therapies. However, because some interventions may cause side effects, more effective pain-relieving measures need to be identified. This study using a non-equivalent group design, evaluated the effects of near-infrared rays on dysmenorrhea among Korean women. The experimental group wore a near-infrared ray abdominal belt for the duration of one menstrual cycle until the end of the menstrual period, while the control group used hot packs. The level of menstrual pain, menstrual pain duration, and pain medicine use were measured. The menstrual pain, average menstrual pain duration, and use of analgesics were reduced in the near-infrared rays group. The results of this study indicate that the near-infrared ray LED belt was effective in reducing menstrual pain, menstrual pain duration compared to the use of analgesics in Korean women with dysmenorrhea. Therefore, near-infrared rays may be used to relieve menstrual pain and improve the quality of life of women with dysmenorrhea in Korea. © 2017 John Wiley & Sons Australia, Ltd.

    The purpose of this study was to investigate the effects of the professional nurse's postpartum breast-feeding support on breast-feeding prevalence for mothers who delivered in Baby-Friendly Hospitals (BFH). This quasi experimental study was designed with a nonequivalent control group post test. The subjects of this study were 55 mothers who were hospitalized in the delivery room of a university hospital which was selected as a BFH in Daegu from October 1, 2005 to June 30, 2006. Twenty nine mothers were assigned to the experimental group and 26 mothers to the control group. Postpartum breast-feeding support by nurses' telephone calls to the experimental group was provided once a week for 4 weeks postpartum and then once a month for 16 weeks postpartum. Four post tests were given at postpartum week 4, 8, 12, and 16. The control group was given a telephone call at postpartum week 4, 8, 12, and 16. The breastfeeding prevalence of the experimental group was significantly higher than that of the control group for each period. Postpartum breast-feeding support by nurses may be a useful intervention to increase breast-feeding prevalence.

    The purpose of this study was to examine effects of enneagram group counseling program on self-identification and depression in nursing college students. Three groups, categorized by how the students solve their conflicts, were selected to identify changes from the program. A quasi-experimental study with a non-equivalent control group and pre posttest design was used. Participants were assigned to the experimental group (n=30) or control group (n=33). The experimental group participated in enneagram group counseling program for 38 hours through eight sessions covering four different topics. Collected data were analyzed using Chi-square test, Fisher's exact test, t-test, and Wilcoxon signed rank test. Total self-identity score for the experimental group was significantly higher than the control group. However, there was no significant difference between the two groups for depression scores. The Assertive and Compliant groups demonstrated significant change in self-identification while the Withdrawn groups did not reveal any change. Results indicate that the enneagram group counseling program is very effective in establishing positive self-identification for nursing college students who face developmental crisis and stressful situations. It is also expected that this program would be useful to enhance the students' confidence through a deeper understanding and acceptance of themselves.

    Despite the high prevalence of back pain and its subsequent effects in post-partum women, intervention programs are scarce. The purpose of this study was to test the effects of a back-pain-reducing program on post-partum women who experienced low-back pain during pregnancy. A non-equivalent control-group pretest-posttest design was used. Pregnant women who attended a hospital for prenatal check-ups and experienced back pain participated in an intervention program (n=27), and the results were compared with women in a control group from another hospital (n=25). At 8 weeks post-partum, the pain intensity, functional limitations were lower in the intervention group than in the control group. However, differences in mean change of the pain intensity and functional limitations between 36 and 39 weeks of gestation and at 8 weeks post-partum were not statistically significant between the groups. Moreover, the flexibility, post-partum functional status, and post-partum depression did not differ significantly between the groups. A back-pain-relief program in this study was not effective to reduce the back-pain intensity in post-partum women and to decrease the associated functional limitations. The implications for nursing practice and directions for future research are discussed.

    The purpose of this study was to identify the effects of hand acupuncture therapy on pain, ROM, ADL, and depression among older people with low back pain and knee joint pain. The research was a quasi-experimental design using a non-equivalent control group pre-post test. The participants were 40 patients, 18 in the experimental group and 22 in the control group. A pretest and 2 posttest were conducted to measure the main variables. For the experimental group, hand acupuncture therapy, consisting of hand acupuncture and press-pellets based on corresponding points, was given. There were statistically significant differences in pain, ROM in knee joint, and ADL in the experimental group but not in depression compared to the control group over two different times. The hand acupuncture therapy was effective for low back pain, knee joint pain, ROM in knee joint and ADL among the elders in this study. Therefore, the hand acupuncture therapy can be utilized in the field of geriatric nursing as a nursing intervention for older people with low back pain and knee joint pain.

    This study was to evaluate the effects of foot reflexology on blood pressure, serum lipids level and life satisfaction in essential hypertension patients. The research design used was a nonequivalent control group pretest-posttest design. Foot Reflexology was used as the experimental treatment from June 23rd, 2003 until August 31st, 2003. Thirty-four subjects were assigned to an experimental group(18) and control group(16). Foot Reflexology was administered twice a week for 6 weeks and self foot Reflexology was administered twice a week for 4 weeks on the experimental group. There was a significant decrease in systolic blood pressure but no significant decrease in diastolic pressure in the experimental group compared to the control group. The total cholesterol level in the experimental group compared to the control group was not significantly decreased after foot reflexology. However, the triglyceride level in the experimental group compared to the control group was significantly decreased after foot reflexology. On the other hand, high density lipoprotein and low density lipoprotein levels in the experimental group compared to the control group was not significantly decreased after foot reflexology. Life satisfaction in the experimental group compared to the control group was significantly improved after foot reflexology. The results proved that foot reflexology was an effective nursing intervention to decrease systolic pressure, and triglyceride but not for the blood cholesterol and to improve life satisfaction. Therefore, blood cholesterol should be further evaluated in a larger group of subjects and for a longer period. Further research is regarded as necessary to evaluate and to compare effects of self-foot reflexology and foot reflexology.

    The primary aim was to demonstrate adherence to a novel 6-week lifestyle intervention program ("Meals, Mindfulness, & Moving Forward" [M 3 ]) designed to help improve lifestyle practices of youth with a history of at least 1 psychotic episode. M 3 used a non-equivalent control group design involving clients from a community early intervention program. Seventeen individuals in the active M 3 program and 16 controls were assessed for secondary outcomes at baseline, 6-weeks, and 12-weeks (6 weeks post-intervention) on cardiometabolic and symptomatic outcomes. The program met its primary aim with 88% (15/17) of participants meeting adherence criteria. Compared with the controls, M 3 participants showed significant improvement in positive psychotic symptoms (P = .002). This pilot study showed that young people involved in a community early intervention program adhered to an activity-based lifestyle program which included mindfulness meditation, yoga and nutrition education, warranting further evaluation with a larger sample size. © 2018 John Wiley & Sons Australia, Ltd.

    Objectives To (1) describe a behavioral intervention designed for patients with elevated pain catastrophizing who are scheduled for knee arthroplasty, and (2) use a quasi-experimental design to evaluate the potential efficacy of the intervention on pain severity, catastrophizing cognitions, and disability. Design Quasi-experimental non-equivalent control group design with a 2 month follow-up. Setting Two university-based Orthopedic Surgery departments. Participants Adults scheduled for knee replacement surgery who reported elevated levels of pain catastrophizing. Patients were recruited from two clinics and were assessed prior to surgery and 2 months following surgery. Intervention A group of 18 patients received a psychologist directed pain coping skills training intervention comprising 8 sessions and the other group, a historical cohort of 45 patients, received usual care. Main Outcome Measures WOMAC Pain and Disability scores as well as scores on the Pain Catastrophizing Scale. Results Two months following surgery, the patients who received pain coping skills training reported significantly greater reductions in pain severity and catastrophizing, and greater improvements in function as compared to the usual care cohort. Conclusion Pain catastrophizing is known to increase risk of poor outcome following knee arthroplasty. The findings provide preliminary evidence that the treatment may be highly efficacious for reducing pain, catastrophizing, and disability, in patients reporting elevated catastrophizing prior to knee arthroplasty. A randomized clinical trial is warranted to confirm these effects. PMID:21530943

    The purpose of the study is to investigate the impact of pedagogical agent's and teacher's role on students' understanding and motivation in the learning of Electrochemistry. Interactive Multimedia Module with Pedagogical Agents, EC Lab (IMMPA EC Lab) was used in this study. IMMPA EC Lab consists of five subunits in Electrochemistry topic. The research was a non-equivalent control group quasi experimental design involving two treatment groups and one control group. The first treatment group studied Electrochemistry with expert agent (Professor T) while the second treatment group studied Electrochemistry with learning companion agent (Lisa). On the other hand, the control group learned Electrochemistry with their Chemistry teacher using the material in the IMMPA EC Lab. The study was conducted at a secondary science school in the Pasir Puteh district involving 74 form four students. The instruments used in this research were the Electrochemistry achievement tests in the form of pre-test and post-test, IMMPA EC Lab and motivation questionnaire. ANCOVA results found that there was no significant difference among the three groups in post-test. On the other hand, One-way ANOVA test proved that there were significant differences for the post-motivation scores between the control group and the treatment groups. Post motivation mean scores for expert agent treatment group and learning companion treatment group surpassed the control group. The study focus on the impact of pedagogical agents with different roles on students' learning and motivation should be promoted. Various versions of pedagogical agents that fulfil the good characteristics should be designed to enhance students' learning and motivation.

    The use of multimedia technologies in education has enabled teachers to simulate final outcomes and assist s-tudents in applying knowledge learned from textbooks, thereby compensating for the deficiency of traditional teach- ing methods. It is important to examine how effective these technologies are in practical use. This study developed online learning-teaching resource platforms using Flash multimedia, providing interactive and integrated features in an easy-to-use user interface, in order to discuss Computer-Aided Drawing (CAD). The study utilized a teaching experiment with a non-equivalent pretest-posttest control group design to test and discuss students' professional cognition, operating skill cognition, and level of learning satisfaction during the learning process. No significant differences emerged between the groups in regards to professional cognition or operation skills cognition. However, a significant difference in learning satisfaction was noted, indicating that the coursework with multimedia Flash produced greater satisfaction than with traditional learning methods. Results are explained in detail and recommendations for further research provided.

    Based on the evaluation findings of the B.E.S.T. Teen Program which aimed at promoting behavioral, emotional, social, and thinking competencies in primary school students, it is argued in this paper that promotion of psychosocial competence to prevent addiction in primary school students is a promising strategy. A total of 382 Primary 5 (Grade 5) and 297 Primary 6 (Grade 6) students from five primary schools in Hong Kong participated in the program. Different evaluation strategies were adopted to evaluate the program. First, objective outcome evaluation adopting a non-equivalent group pretest-posttest experimental-control group design was conducted to examine change in the students. Second, to gauge students' perceptions of the program, subjective outcome evaluation was conducted. The evaluation findings basically converged to tentatively suggest that young adolescents benefited from participating in the program. Implications on the development, implementation, and evaluation of addiction prevention programs for teenagers are discussed.

    Hypertrophic scarring and depression are the principal problems of burn rehabilitation. This study was done to verify the effects of skin rehabilitation massage therapy (SRMT) on pruritus, skin status, and depression for Korean burn survivors. A pretest-posttest design using a nonequivalent control group was applied to examine the effects of SRMT for 3 months in a group of 18 burn survivors. The major dependent variables-including pruritus, objective and subjective scar status, and depression-were measured at the beginning and at the end of the therapy to examine the effects of SRMT. Burn survivors receiving SRMT showed reduced pruritus, improved skin status, and depression. The remaining scar also showed improvement in skin pigmentation, pliability, vascularity, and height (compared to the surrounding skin) as measured on the Vancouver Scar Scale (VSS). The findings demonstrate that SRMT for burn survivors may improve their scars both objectively and subjectively, and also reduce pruritus and depression.

    A blended learning can be a useful learning strategy to improve the quality of fever and fever management education for pediatric nurses. This study compared the effects of a blended and face-to-face learning program on pediatric nurses' childhood fever management, using theory of planned behavior. A nonequivalent control group pretest-posttest design was used. A fever management education program using blended learning (combining face-to-face and online learning components) was offered to 30 pediatric nurses, and 29 pediatric nurses received face-to-face education. Learning outcomes did not significantly differ between the two groups. However, learners' satisfaction was higher for the blended learning program than the face-to-face learning program. A blended learning pediatric fever management program was as effective as a traditional face-to-face learning program. Therefore, a blended learning pediatric fever management-learning program could be a useful and flexible learning method for pediatric nurses.

    The purpose of this study was to test the effects of infant massage (auditory (mother's voice), tactile/kinesthetic (massage) and visual (eye to eye contact) stimulation) on weight and height of infant and mother-infant interaction with normal infants over a period of 4 weeks. This study was designed as a nonequivalent control group pretest-posttest design. The experimental group infants (aged 2-6 months) participated in one of the infant massage programs at the health district center for 4 weeks. The control group (N=26) was paired with the experimental group (N=26) by matching the infant's age and sex. Infant weight, height, and mother-infant interaction were measured two times and recordings of the mother-infant interaction were done using the video equipment in a room at the health center for 10 minutes. After 4 weeks of massage, there were no significant differences weight gain and height increase between the two groups. Comparison of the total scores for the mother-infant interaction between the two groups showed a significant difference (t=5.21, p=.000). There were also significant differences on maternal response (t=3.78, p=000), infant response (t=5.71, p=000) and dyadic response (t=4.05, p=000) in the mother-infant interaction between the two groups. Overall, the results of this study reassure that infant massage facilitates the mother-infant interaction for infants and mothers who give massage to their baby.

    Annisa, Fitri; Nurhaeni, Nani; Wanda, Dessie

    Intravenous fluid therapy is an invasive procedure which may increase the risk of patient complications. One of the most common of these is phlebitis, which may cause discomfort and tissue damage. Therefore, a nursing intervention is needed to effectively treat phlebitis. The purpose of this study was to investigate the effectiveness of applying a warm compression intervention to reduce the degree of phlebitis. A quasi-experimental pre-test and post-test design was used, with a non-equivalent control group. The total sample size was 32 patients with degrees of phlebitis ranging from 1 to 4. The total sample was divided into 2 interventional groups: those patients that were given 0.9% NaCl compresses and those given warm water compresses. The results showed that both compresses were effective in reducing the degree of phlebitis, with similar p values (p = .000). However, there was no difference in the average reduction score between the two groups (p = .18). Therefore, a warm water compress is valuable in the treatment of phlebitis, and could decrease the degree of phlebitis both effectively and inexpensively.

    The present study examined the comparative effects of a prediction/discussion-based learning cycle, conceptual change text (CCT), and traditional instructions on students' understanding of genetics concepts. A quasi-experimental research design of the pre-test-post-test non-equivalent control group was adopted. The three intact classes, taught by the same science teacher, were randomly assigned as prediction/discussion-based learning cycle class (N = 30), CCT class (N = 25), and traditional class (N = 26). Participants completed the genetics concept test as pre-test, post-test, and delayed post-test to examine the effects of instructional strategies on their genetics understanding and retention. While the dependent variable of this study was students' understanding of genetics, the independent variables were time (Time 1, Time 2, and Time 3) and mode of instruction. The mixed between-within subjects analysis of variance revealed that students in both prediction/discussion-based learning cycle and CCT groups understood the genetics concepts and retained their knowledge significantly better than students in the traditional instruction group.

    2006-12-01

    Pain is reported to occur in the majority of patients with advanced cancer and is one of the main reasons for referral to a hospital specialist palliative care team. Yet despite this, there is a paucity of research into the impact the hospital specialist palliative care team has on pain control in patients. A non-equivalent control group design using a quota sample investigated 100 cancer patients who had been admitted to hospital for symptom control. Fifty patients received specialist hospital palliative care team intervention compared with 50 patients receiving traditional care. Outcome was assessed using the Palliative Care Assessment (PACA) tool on three occasions. There was no difference between the groups on the initial assessment and the results indicated that all cancer patients admitted to hospital had a significant improvement in their pain control. However, the patients who had the additional input of the palliative care team demonstrated a statistically significant greater improvement than the control group (P<0.001). Potential explanations are made for the results including the enhanced knowledge and skills of the hospital specialist palliative care team.

    Institutional wheelchair-bound older adults often do not get regular exercise and are prone to health problems. The aim of this study was to test the effects of a 12-week qigong exercise program on the physiological and psychological health of wheelchair-bound older adults in long-term care facilities. Study design was quasi-experimental, pre-post test, nonequivalent control group. Participants comprised a convenience sample of 72 wheelchair-bound older adults (qigong = 34; control = 38). The qigong group exercised 35 min/day, 5 days/week for 12 weeks. Measures for physical health (blood pressure, heart rate variability, and distal skin temperature) and psychological health (Brief Symptom Rating Scale-5) were collected before and during study Weeks 4, 8, and 12. The qigong group participants' blood pressure, distal skin temperature, and psychological health were significantly improved (all p < .001). These findings suggest that qigong exercise is a suitable daily activity for elderly residents in long-term care facilities and may help in the control of blood pressure among older adults.

    Oral mucositis is a common, debilitating complication of cancer patients undergoing chemotherapy and radiotherapy, occurring in about 40 percent cases. Mucositis may limit the patient's ability to tolerate chemotherapy or radiation therapy, and nutrition status is compromised. The aim of the study was to assess the effect of Indian turmeric powder with honey as a complementary therapy on treatment induced oral mucositis. In the study, quasi experimental non-equivalent control group pre test post-test design was used and non-probability purposive sampling technique was adopted to select 60 cancer patients with treatment induced oral mucositis, 30 each in experimental and control group. The independent 't' value for post-test 2 and 3 (post-test 2: 2.86 for WHO OMAS and 4.58 for MPJ OMAS, post test 2: 5.42 for WHO OMAS and 7.2 for MPJ OMAS; p < 0.05) were significant between experimental and control group. It is inferred that the application of Indian turmeric and honey on treatment-induced oral mucositis is effective.

    The present study was targeted to observe the impact of neuropsychological rehabilitation on activities of daily living (ADL) and community reintegration of patients with traumatic brain injury (TBI). Based on purposive sampling technique, ten patients with TBI falling in the age range of 20-40 years and fulfilling the inclusion and exclusion criteria were chosen from All India Institute of Speech and Hearing, Mysuru, India. A quasi-experimental design, i.e., nonequivalent control group design was chosen for the study. Patients were assessed on Luria-Nebraska Neuropsychological Battery for Adults, Cognitive Symptoms Checklist, and Community Integration Questionnaire. Patients in experimental group were given neuropsychological rehabilitation for 6 months. Brainwave-R and Talking Pen were used as rehabilitative tools. Patients with TBI have significant neuropsychological deficits observed in memory, visuo-spatial organization, arithmetic, spelling, writing, fine motor coordination, and executive functioning. Neuropsychological deficits have a major impact on ADL and community reintegration. Neuropsychological rehabilitation is effective in rehabilitating neuropsychological deficits, which in turn leads to improvement in ADL and community reintegration. Neuropsychological rehabilitation should be one of the major goals in rehabilitation procedures for patients with TBI in order to bring overall improvement in them.

    The Aspergillus fumigatus lectin AFL was recently described as a new member of the AAL lectin family. As a lectin from an opportunistic pathogen, it might play an important role in the interaction of the pathogen with the human host. A detailed study of structures of AFL complexed with several monosaccharides and oligosaccharides, including blood-group epitopes, was combined with affinity data from SPR and discussed in the context of previous findings. Its six binding sites are non-equivalent, and owing to minor differences in amino-acid composition they exhibit a marked difference in specific ligand recognition. AFL displays a high affinity in the micromolar range towards oligosaccharides which were detected in plants and also those bound on the human epithelia. All of these results indicate AFL to be a complex member of the lectin family and a challenging target for future medical research and, owing to its binding properties, a potentially useful tool in specific biotechnological applications.

    This study was conducted to examine effects of a small group-based cardiocerebrovascular disease (CVD) prevention education program on knowledge, stage of change and health behavior among male bus drivers with CVD risk factors. A non-equivalent control group pretest-posttest design was used. Participants were 68 male bus drivers recruited from two urban bus companies. Participants from the two groups were selected by matching age, education and risk factors. Experimental group (n=34) received a small group-based CVD prevention education program 8 times over 6 weeks and 3 times through telephone interviews at 2-week intervals. Data were collected between December, 2010 and March, 2011, and were analyzed using chi-square test, t-test, and repeated measure analysis of variance with SPSS/Win18.0. Experimental group showed significantly higher scores in CVD prevention knowledge (p<.001) and health behavior (p<.001) at 6 and 12 weeks after intervention. Participants in pre-contemplation and contemplation stages made progress to contemplation and action. This was significantly better at 6 and 12 weeks after intervention (p<.001). Results suggest that small group-based education programs for CVD prevention are effective in increasing knowledge, stage of change, and health behavior to prevent CVD among male bus drivers with CVD risk.

    The purpose of this study was to investigate the effects of using a Coaching Program on Comprehensive Lifestyle Modification with pregnant women who have gestational diabetes. The research design for this study was a non-equivalent control group quasi-experimental study. Pregnant women with gestational diabetes were recruited from D women's hospital located in Gyeonggi Province from April to October, 2013. Participants in this study were 34 for the control group and 34 for the experimental group. The experimental group participated in the Coaching Program on Comprehensive Lifestyle Modification. The program consisted of education, small group coaching and telephone coaching over 4weeks. Statistical analysis was performed using the SPSS 21.0 program. There were significant improvements in self-care behavior, and decreases in depression, fasting blood sugar and HbA1C in the experimental group compared to the control group. However, no significant differences were found between the two groups for knowledge of gestational diabetes mellitus. The Coaching Program on Comprehensive Lifestyle Modification used in this study was found to be effective in improving self-care behavior and reducing depression, fasting blood sugar and HbA1C, and is recommended for use in clinical practice as an effective nursing intervention for pregnant women with gestational diabetes.

    This study was done to identify effects of a smoking cessation program including telephone counseling and text messaging using stages of change for outpatients who have had a myocardial infarction (MI). This research was a quasi-experimental design with a nonequivalent control group pretest-posttest. The participants were 48 outpatients (experimental group=24, control group=24) recruited from one university hospital. They were randomly assigned to one of two groups: (a) an experimental group with telephone counseling (once a week) and text messaging (five times a week) using stages of change, and (b) a control group with traditional telephone counseling (once a month). Efficacy of the intervention was measured by comparing the two groups on smoking-related variables at 3 weeks and 12 weeks. At the 3-week and 12-week measurements, there were significant differences between the experimental and control groups on smoking cessation self-efficacy (p<.001), nicotine dependence (p<.001), CO levels (p<.001), and smoking cessation rates (p<.001). The results indicate that the smoking cessation program including telephone counseling and text messaging using stages of change is effective for outpatients after a MI. Further attention should be paid to the intensity of the smoking cessation program and periods for long-term follow-up.

    The purpose of this study was to examine the effects of an inpatient pulmonary rehabilitation program on dyspnea, exercise capacity, and health related quality of life in inpatients with chronic lung disease. This quasi experimental study was designed with a nonequivalent control group pre-post test time series. Twenty three patients were assigned to the experimental group and nineteen to the control group. The inpatient pulmonary rehabilitation program was composed of upper and lower extremity exercise, breathing retraining, inspiratory muscle training, education, relaxation and telephone contacts. This program consisted of 4 sessions with inpatients and 4 weeks at home after discharge. The control group was given a home based pulmonary rehabilitation program at the time of discharge. The outcomes were measured by the Borg score, 6MWD and the Chronic Respiratory Disease Questionnaire(CRQ). There was a statistically significant difference in dyspnea between the experimental group and control group, but not among time sequence, or interaction between groups and time sequence. Also significant improvements in exercise capacity and health related quality of life were found only in the experimental group. An Inpatient pulmonary rehabilitation program may be a useful intervention to reduce dyspnea, and increase exercise capacity and health related quality of life for chronic lung disease patients.

    Health-related quality of life (HRQOL) that is good is regarded as the goal of elderly residential care. However, limited evidence exists indicating a promising intervention that can achieve this goal. The aim of this study is to examine the effect of Tai Chi on HRQOL in nursing home residents. A nonequivalent pretest-posttest control-group design. A convenience sample of 139 residents from six nursing homes in Hong Kong was used. The experimental group (n=66) joined a 26-week Tai Chi program, while the control group (n=73) continued with usual daily activities. The physical and mental components of HRQOL were designated as the dependent variables. Resident satisfaction was considered as a covariate. Doubly multivariate repeated measures analysis of covariance was done to examine the intervention effect. After adjusting for the confounding effect of resident satisfaction, a statistically significant difference (p<0.05) in the physical and mental components of HRQOL between the experimental and control groups was found. Findings showed significant improvement in HRQOL after residents practiced Tai Chi. These investigators contribute additional knowledge about the health benefits of Tai Chi among nursing home residents and indicates support for its use in this population to improve HRQOL. Tai Chi has unique characteristics as a health exercise that is particularly suitable for nursing home residents. The inclusion of Tai Chi exercise in elderly residential care practice is recommended.

    The aim of this study was to investigate whether a four-month occupational based health-promoting programme for older persons living in community dwellings could maintain/improve their general health and well-being. Further, the aim was to explore whether the programme facilitated the older persons' occupational adaptation. The study had a quasi-experimental design, with a non-equivalent control group combined with semi-structured interviews. The intervention group comprised 22 participants, and the control group 18. Outcomes were measured using the Short Form 36, Life Satisfaction Index-Z and Meaningful Activity Participation Assessment. Content analysis, based on concepts from the Model of Occupational Adaptation, was used to analyse the interviews. The intervention group showed statistically significant improvements in general health variables such as vitality and mental health, and positive trends for psychological well-being. There were no statistically significant differences between the intervention group and the control group, but the groups were not fully matched. The qualitative analysis based on Occupational Adaptation pointed out social aspects as a compliment to the overall results. Participating in meaningful, challenging activities in different environments stimulates the occupational adaptation process; this is something occupational therapists could use to empower older persons to find their optimal occupational lives.

    To evaluate effectiveness of a face-to-face and an online fatigue self-management programme and to compare these to two control groups (information-only and no-intervention) in a sample of adults (n = 115) with neurological conditions reporting extreme fatigue. Non-equivalent pre-test post-test control group design using the Fatigue Impact Scale, Personal Wellbeing Index and Activity Card Sort as primary outcome measures. Participants in the two intervention groups and the information-only group showed clinically significant improvements in fatigue over time (p < 0.05). When compared to the no-intervention group, face-to-face participants showed significantly greater improvement in overall and cognitive fatigue, while participants in the online group showed significant improvement in self-efficacy and stress. Participation in either the online or face-to-face programme appears to result in improved self-management, however, with different potency depending on outcomes. The improvement in the online information only group further complicates the understanding of the results. With few other comparisons of online and face-to-face self-management protocols available, further research is needed to understand differential impacts which may be related to the delivery format, the rural versus urban split of participants or other unknown factors.

    The purpose of this study was to develop a relapse prevention program (RPP) and examine the effects of the RPP on insight, empowerment, and treatment adherence in patients with schizophrenia. A non-equivalent control group pretest-posttest design was used. Participants were 54 inpatients who had a diagnosis of schizophrenia (experimental group: 26, control group: 28). The study was carried out from February 7, 2012 to February 6, 2013. Over a 10-day period prior to discharge each participant in the experimental group received three one-hour sessions of RPP a one-to-one patient-nurse interaction. Data were collected using Assess Unawareness of Mental Disorder (SUMD), Empowerment Scale, and Insight and Treatment Attitude Questionnaire (ITAQ) and analyzed using PASW 18.0 with chi-square test, independent t-test, Mann-Whitney U test, and ANCOVA. The experimental group had a significant increase in insight and treatment adherence compared to the control group. However, there was no significant difference in empowerment between the two groups. Findings indicate that the RPP for patients with schizophrenia was effective in improving insight and treatment adherence. A longitudinal study is needed to confirm the persistence of these effects of RPP in patients with schizophrenia. © 2017 Korean Society of Nursing Science

This research was conducted between June 2009 and April 2010 as a nonequivalent control group non-synchronized design. The study population was 44 third year nursing students who enrolled in a college of nursing, A University in Korea. The nursing students were divided into the CBL and the control group. The intervention was the CBL with three cases using video. The controls attended a traditional live lecture on the same topics. With questionnaires objective clinical decision-making, subjective clinical decision-making, and learning motivation were measured before the intervention, and 10 weeks after the intervention. Significant group differences were observed in clinical decision-making and learning motivation. The post-test scores of clinical decision-making in the CBL group were statistically higher than the control group. Learning motivation was also significantly higher in the CBL group than in the control group. These results indicate that CBL using video is effective in enhancing clinical decision-making and motivating students to learn by encouraging self-directed learning and creating more interest and curiosity in learning.

    The Responsive Leadership Intervention (RLI) is a multi-faceted intervention. We evaluated the influence of the RLI on i) responsive leadership practices by team leaders; ii) health care aides' (HCAs) self-determination; iii) HCAs' perceived ability to provide individualized care. A quasi-experimental repeated measures non-equivalent control group design was used to assess participant outcomes in four long-term care facilities (two control, two intervention) across four time periods. Change from baseline to 1-month post-intervention was greater in the intervention group than control group for Individualized Care (IC) (p = 0.001), but not for Self Determination (p = 0.26). Perceived levels of responsive leadership was greater following the intervention among participants with baseline measures that were less than the median (p = 0.007), but not if greater. At 3-months post-intervention, the intervention group retained 32% of the difference from control in IC, and 49% of the difference from control in responsive leadership; at 6-months post-intervention, 35% and 28%, respectively. The RLI is a feasible method for improving responsive leadership practices and individualized care. Copyright © 2017 Elsevier Inc. All rights reserved.

    The study aimed to develop a mind-body therapeutic program and evaluate its effects on mitigating uncertainty, anxiety, and implantation rate of second-trial in vitro fertilization (IVF) women. This study employed a nonequivalent control group nonsynchronized design. The conceptual framework and program content were developed from a preliminary survey of eight infertile women and the extensive review of the literature. Program focuses on three uncertainty-induced anxieties in infertile women: cognitive, emotional, and biological responses. To evaluate the effect of the intervention, the infertile women with unknown cause preparing for a second IVF treatment were sampled at convenience (26 experimental and 24 control). The experimental group in the study showed greater decrease in uncertainty and anxiety in premeasurements and postmeasurements than the control group did. However, no statistically significant differences in the implantation rate between groups were observed. This study is meaningful as the first intervention program for alleviating uncertainty and anxiety provided during the IVF treatment process. The positive effects of the mind-body therapeutic program in alleviating both uncertainty and anxiety have direct meaning for clinical applications. Copyright © 2014. Published by Elsevier B.V.

    2016-01-01

    Previous studies have demonstrated that pharmaceutical equivalence and pharmacokinetic equivalence of generic antibiotics are necessary but not sufficient conditions to guarantee therapeutic equivalence (better called pharmacodynamic equivalence). In addition, there is scientific evidence suggesting a direct link between pharmacodynamic nonequivalence of generic vancomycin and promotion of resistance in Staphylococcus aureus. To find out if even subtle deviations from the expected pharmacodynamic behavior with respect to the innovator could favor resistance, we studied a generic product of piperacillin-tazobactam characterized by pharmaceutical and pharmacokinetic equivalence but a faulty fit of Hill’s Emax sigmoid model that could be interpreted as pharmacodynamic nonequivalence. We determined the impact in vivo of this generic product on the resistance of a mixed Escherichia coli population composed of ∼99% susceptible cells (ATCC 35218 strain) and a ∼1% isogenic resistant subpopulation that overproduces TEM-1 β-lactamase. After only 24 hours of treatment in the neutropenic murine thigh infection model, the generic amplified the resistant subpopulation up to 20-times compared with the innovator, following an inverted-U dose-response relationship. These findings highlight the critical role of therapeutic nonequivalence of generic antibiotics as a key factor contributing to the global problem of bacterial resistance. PMID:27191163

    This study was done to determine the effects of weight management program using self-efficacy in middle-aged obese women. The study also attempted to measure the effects of the program on the weight efficacy lifestyle, body composition, and depression. The research design of this study was a nonequivalent control group pretest-posttest design. The experimental group consisted of 21 middle-aged obese women and another 21 middle-aged obese women in the control group. The women in the experimental group participated in the weight management program for 12 weeks using self-efficacy. The weight management program using self-efficacy included education on effects of exercise for weight control, aerobic exercise program, muscle training and counseling through the telephone. After 12 weeks of participation in the program, BMI (p<.0001), body fat % (p<.0001), abdominal fat (p<.0001), in the experimental group were significantly decreased compared to the control group. Weight self-efficacy lifestyle (p<.0001) and depression (p=.006) in the experimental group were significantly improved after the program compared to the control group. According to these findings, weight management program self-efficacy for middle-aged obese women could increase weight efficacy lifestyle, and decrease depression, BMI, body fat, and abdominal fat. The result also suggested that the increasing weight efficacy and lifestyle help the obese women to perform and continue exercise. This program could be used in the community such as public health center for weight care and mental health promotion of middle-aged obese women.

    2013-06-01

    This is a report of a study which evaluated simulation-based learning as a teaching strategy for improving participants' ENP reading proficiency in the senior college program of students whose first language is Chinese, not English. Simulation-based learning is known to be one of most effective teaching strategies in the healthcare professional curricula, which brings a clinical setting into the classroom. However, developing English reading skills for English written nursing journals through simulation-based learning in the nursing curricula, is largely unknown. We used a quasi-experimental approach with nonequivalent control group design to collect the causal connections between intervention and outcomes. 101 students were enrolled in this study (response rate 92.6%) of these 48 students volunteered for the intervention group, and 53 students for the control group. The findings indicated that the intervention group had significantly higher mean scores in ENP reading proficiency with unknown words in the article (p=.004), vocabulary (p<.001), and comprehension (p<.001) compared to the control group. Also, the intervention students showed more improvement in their English reading, both from quantitative and qualitative findings. Simulation-based learning may have some advantages in improving the English reading ability on English written nursing journals among nursing students. However, the benefits to the students of this study is still to be determined, and further exploration is needed with well designed research and a universal method of outcome measurement.

Teacher self-efficacy and their confidence to teach specific STEM subjects; 2.) Teaching outcome expectancy beliefs concerning the impact of actions by teachers on student learning; and 3.) Teacher awareness of STEM careers. High school science and technology education teachers participating in the Teachers and Researchers Advancing Integrated Lessons in STEM (TRAILS) project experimental group attended a ten-day summer professional development institute designed to educate teachers in using an integrated STEM education model to implement integrated STEM lessons. The research design utilized a quasi-experimental nonequivalent comparison group design that incorporated an experimental group and an untreated comparison group with both pretest, posttest, and delayed posttest assessments on non-randomized participants. Teacher self-efficacy has been identified as a key factor in effective teaching and student learning, and teacher awareness of STEM careers impacts students as they consider career choices. The T-STEM Survey for teachers was given for the pretest and posttest assessments to measure attitudes and beliefs toward the specific constructs of this study. Significant effects of the TRAILS professional development were found in the teacher group (experimental or comparison) and teacher subject (technology or science) in pretest and posttest scores using cumulative link models for the constructs of teacher self-efficacy and beliefs to teach STEM subjects, teacher outcome expectancy beliefs, and teacher awareness of STEM careers. Effect sizes ranged from small to large varying by construct and assessment time. Highly significant p-values and effect sizes revealed impacts on science teachers were greater when teacher subject groups were analyzed separately.

    The purposes of this study were to develop an educational program to reduce the use of physical restraints for caregivers in geriatric hospitals and to evaluate the effects of the program on caregivers' knowledge, attitude and nursing practice related to the use of physical restraints. A quasi experimental study with a non-equivalent control group pretest-posttest design was used. Participants were recruited from two geriatric hospitals. Eighteen caregivers were assigned to the experimental group and 20 to the control group. The data were collected prior to the intervention and at 6 weeks after the intervention through the use of self-administered questionnaires. Descriptive statistics, X(2) test, Fisher's exact probability test, and Mann-Whitney U test were used to analyze the data. After the intervention, knowledge about physical restraints increased significantly in experimental group compared to the control group. However, there were no statistically significant differences between the groups for attitude and nursing practice involving physical restraints. Findings indicate that it is necessary to apply knowledge acquired through educational programs to nursing practice to reduce the use of physical restraints. User friendly guidelines for physical restraints, administrative support of institutions, and multidisciplinary approaches are required to achieve this goal.

    This study was conducted to verify the effects of a memory and visual-motor integration program for older adults based on self-efficacy theory. A non-equivalent control group pretest-posttest design was implemented in this quasi-experimental study. The participants were 62 older adults from senior centers and older adult welfare facilities in D and G city (Experimental group=30, Control group=32). The experimental group took part in a 12-session memory and visual-motor integration program over 6 weeks. Data regarding memory self-efficacy, memory, visual-motor integration, and depression were collected from July to October of 2014 and analyzed with independent t-test and Mann-Whitney U test using PASW Statistics (SPSS) 18.0 to determine the effects of the interventions. Memory self-efficacy (t=2.20, p=.031), memory (Z=-2.92, p=.004), and visual-motor integration (Z=-2.49, p=.013) increased significantly in the experimental group as compared to the control group. However, depression (Z=-0.90, p=.367) did not decrease significantly. This program is effective for increasing memory, visual-motor integration, and memory self-efficacy in older adults. Therefore, it can be used to improve cognition and prevent dementia in older adults. © 2017 Korean Society of Nursing Science

    This study examines the effectiveness of a new constructivist curriculum model (Powerful Ideas in Physical Science) in improving prospective teachers’ understanding of science concepts, in fostering a learning environment supporting conceptual understanding, and in promoting positive attitudes toward learning and teaching science and chemistry in particular. A non-equivalent pretest post-test control-group design was employed. Analysis of covariance and repeated-measures analyses of variance were performed to analyze the scores on concept tests and attitude surveys. Data from videotaped observations of laboratory sessions and interviews of prospective teachers were analyzed by employing a naturalistic inquiry method to provide insights into the process of science learning and teaching for the teacher trainees. The interpretations were made based on the findings that could be corroborated by both methodologies. Conclusions and limitations of the present study as well as recommendations for future implementation of constructivist science curriculum in general are also included.

    This study aimed to estimate the effects of a health mentoring program on fasting blood sugar, total cholesterol, triglyceride, physical activity, self care behavior and social support changes among community-dwelling vulnerable elderly individuals with diabetes. A non-equivalent control group pre-post-test design was used. Participants were 70 community-dwelling vulnerable elderly individuals with diabetes. They were assigned to the experimental (n=30) or comparative (n=30) or control group (n=28). The experimental group participated in the health mentoring program, while the comparative group participated in health education program, the control group did not participate in any program. Data analyses involved a chi-square test, Fisher's exact test, a generalized linear model, and the Bonferroni correction, using SPSS 23.0. Compared to the control group, the experimental and comparative groups showed a significant decrease in fasting blood sugar, total cholesterol, and triglyceride. Compared to the comparative and control groups, the experimental group showed significant improvement in self care behavior. However, there were no statistical differences in physical activity or social support among the three groups. These findings indicate that the health mentoring program is an effective intervention for community-dwelling vulnerable elderly individuals with diabetes. This program can be used as an efficient strategy for diabetes self-management within this population. © 2018 Korean Society of Nursing Science.

    The purpose of this study was to examine the effects of a cultural competence improvement program for maternity nurses. A quasi-experimental study using a non-equivalent control group pre and posttest design was used. Participants were 67 maternity nurses caring for multicultural pregnant women in G city. The cultural competence improvement program was developed based on the 3-D Puzzle Model and was provided using case-based small group learning methods for the experimental group (n=31). The control group (n=36) did not receive any intervention. Data were collected using self-report structured questionnaires at two time points: prior to the intervention and after the intervention and were analyzed with descriptive statistics, χ²-test, and t-test. Compared to the control group, the experimental group reported significant positive changes for cultural knowledge (t=6.39, p<.001), cultural awareness (t=3.50, p<.001), and cultural acceptance (t=4.08, p<.001). However, change in cultural nursing behaviors (t=0.92, p=.067) was not significantly different between the two groups. Findings from this study indicate that a cultural competence improvement program with case-based small group learning is a useful intervention strategy to promote multicultural maternity care. Further, strategies to improve cultural nursing behavior should be developed to promote culturally congruent nursing care.

    The purpose of this study was to develop and evaluate a school-based peer leader centered smoking prevention program. Non-equivalent control group with a pre/post-test design was used. Students (n=174) in two boys' junior high schools located in D city, Korea participated with 85 being selected for the experimental group and 89 for the control group. Five sessions were given to the experimental group and a 50 minute lecture to the control group. Knowledge, attitude, non-smoking intention, and non-smoking efficacy were measured for the both experimental and control group at two weeks before the program and one month after the program was completed. Data were analyzed using χ²-test, Fisher's exact test, independent t-test and paired t-test with the SPSS 21.0 program. The experimental group showed higher overall knowledge, negative attitude toward smoking, and higher non-smoking intention and efficacy. After receiving the school based peer leader centered smoking prevention program scores for attitude toward smoking and non-smoking efficacy increased in the experimental group were higher than in the control group. The school-based peer leader centered smoking prevention program needs longitudinal evaluation, but from this study, there is an indication that this program can be used with junior high school students and effectively change students' attitude toward smoking and promote non-smoking efficacy.

    The purpose of this study was to determine the effects of foot reflexology on fatigue and insomnia in patients suffering from coal workers' pneumoconiosis. This study was a quasi-experimental study of pre-test and post-test design in a non-equivalent control group. The subjects of this study consisted of both the experimental group of twenty-nine and the control group of thirty coal workers' pneumoconiosis patients. Data was collected from December 10, 2002 to February 15, 2003. Foot reflexology was performed for 60 minutes twice a week through five weeks in the experimental group, but none in the control group. To evaluate the effects of foot reflexology, the scores of fatigue and insomnia were measured before and after the experiment in both groups. Fatigue was evaluated by Fatigue Symptoms Inventory. Insomnia was measured with the visual analogue scale (VAS). Data of this experiment was analyzed by Chi-square test, t-test, unpaired t-test and Repeated Measures ANOVA with the SAS Program. The scores of fatigue and insomnia decreased in the experimental group but not in the control group. There was a significant difference of fatigue and insomnia between the two groups. It is suggested that foot reflexology might have beneficial effects on reducing fatigue and insomnia in patients suffering from coal workers' pneumoconiosis, and can be recommended as a nursing intervention program for patients with coal workers' pneumoconiosis.

    To generate changes in nursing practice introducing an evidence-based clinical practice (EBCP) model through a participatory process. To evaluate the effectiveness of the changes in terms of nurse-sensitive outcome (NSO). For international nursing science, it is necessary to explore the reasons for supporting EBCP and evaluate the real repercussions and effectiveness. A mixed methods study with a sequential transformative design will be conducted in the bone marrow transplant unit of a tertiary-level Spanish hospital, in two time periods >12 months (date of approval of the protocol: 2006). To evaluate the effectiveness of the intervention, we will use a prospective quasi-experimental design with two non-equivalent and non-concurrent groups. NSO and patient health data will be collected: (a) impact of psycho-social adjustment; (b) patient satisfaction; (c) symptom control; (d) adverse effects. All patients admitted during the period of time will be included, and all staff working on the unit during a participatory action research (PAR). The PAR design will be adopted from a constructivist paradigm perspective, following Checkland's "Soft Systems" theoretical model. Qualitative techniques will be used: 2-hour group meetings with nursing professionals, to be recorded and transcribed. Field diaries (participants and researchers) will be drawn up and data analysis will be carried out by content analysis. PAR is a rigorous research method for introducing changes into practice to improve NSO.

    This study was conducted to examine effects of a learning portfolio by identifying the learning of nursing students taking a learning portfolio-utilized nursing management class. A non-equivalent control group pretest-posttest design was used. Participants were 83 senior students taking the nursing management course in one of the Departments of Nursing at 2 Universities. Experimental group (n=42) received a learning portfolio-utilized nursing management class 15 times over 15 weeks (3 hours weekly). Self-directed learning abilities, approaches to learning and learning flow of the participants were examined with self-report structured questionnaires. Data were collected between September 2 and December 16, 2014, and were analyzed using chi-square test, Fisher's exact test, independent t-test and ANCOVA with SPSS/PC version 21.0. After the intervention the experimental group showed significant increases in self-directed learning abilities, deep approaches to learning and learning flow compared to the control group. However, no significant difference was found between groups for surface approaches to learning. Learning activities using the learning portfolios could be effective in cultivating the learning competency for growth of knowledge, technology and professionalism by increasing personal concentration and organization ability of the nursing students so that they can react to the rapidly changing environment.

    Meager research has been carried out to determine the effectiveness of the token economy among patients behaving violently in mental hospitals. The purpose of this study was to examine the effectiveness of the Short-Term Token Economy (STTE) on violent behavior among chronic psychiatric in-patients. A nonequivalent control group design method was utilized. Participants in an experimental group (n=22) and control group (n=22) took part in this study from January to April, 2008. Observation on aggressive behavior among male in-patients in one hospital as a baseline was made during the week before the behavior modification program and measurement of aggressive behavior was done using the Overt Aggression Scale (OAS), which includes verbal attacks, property damage and physical attacks. The aggressive behavior scores of the experimental group decreased, those of the control group, scores showed an increase after the eight-week behavior modification program utilizing STTE. The results of the study indicate that STTE is effective in reducing the incidence of aggressive behavior among male in-patients in psychiatric hospitals. The outcome of this study should be helpful in reducing the use of coercive measures or psychoactive medication in controlling the violent behavior among in-patients in hospitals.

  5. On the Number of Non-equivalent Ancestral Configurations for Matching Gene Trees and Species Trees.

    An ancestral configuration is one of the combinatorially distinct sets of gene lineages that, for a given gene tree, can reach a given node of a specified species tree. Ancestral configurations have appeared in recursive algebraic computations of the conditional probability that a gene tree topology is produced under the multispecies coalescent model for a given species tree. For matching gene trees and species trees, we study the number of ancestral configurations, considered up to an equivalence relation introduced by Wu (Evolution 66:763-775, 2012) to reduce the complexity of the recursive probability computation. We examine the largest number of non-equivalent ancestral configurations possible for a given tree size n. Whereas the smallest number of non-equivalent ancestral configurations increases polynomially with n, we show that the largest number increases with [Formula: see text], where k is a constant that satisfies [Formula: see text]. Under a uniform distribution on the set of binary labeled trees with a given size n, the mean number of non-equivalent ancestral configurations grows exponentially with n. The results refine an earlier analysis of the number of ancestral configurations considered without applying the equivalence relation, showing that use of the equivalence relation does not alter the exponential nature of the increase with tree size.

    The literature suggests that person-centred care can contribute to quality of life and wellbeing of nursing home residents, relatives and staff. However, there is sparse research evidence on how person-centred care can be operationalised and implemented in practice, and the extent to which it may promote wellbeing and satisfaction. Therefore, the U-Age nursing home study was initiated to deepen the understanding of how to integrate person-centred care into daily practice and to explore the effects and meanings of this. The study aims to evaluate effects and meanings of a person-centred and thriving-promoting intervention in nursing homes through a multi-centre, non-equivalent controlled group before-after trial design. Three nursing homes across three international sites have been allocated to a person-centred and thriving-promoting intervention group, and three nursing homes have been allocated to an inert control group. Staff at intervention sites will participate in a 12-month interactive educational programme that operationalises thriving-promoting and person-centred care three dimensions: 1) Doing a little extra, 2) Developing a caring environment, and 3) Assessing and meeting highly prioritised psychosocial needs. A pedagogical framework will guide the intervention. The primary study endpoints are; residents' thriving, relatives' satisfaction with care and staff job satisfaction. Secondary endpoints are; resident, relative and staff experiences of the caring environment, relatives' experience of visiting their relative and the nursing home, as well as staff stress of conscience and perceived person-centredness of care. Data on study endpoints will be collected pre-intervention, post-intervention, and at a six-month follow up. Interviews will be conducted with relatives and staff to explore experiences and meanings of the intervention. The study is expected to provide evidence that can inform further research, policy and practice development on if and how person-centred care may improve wellbeing, thriving and satisfaction for people who reside in, visit or work in nursing homes. The combination of quantitative and qualitative data will illuminate the operationalisation, effects and meaning of person-centred and thriving-promoting care. The trial was registered at ClinicalTrials.gov March 19, 2016, identifier NCT02714452 .

    Background and purpose: The purpose of this study was to investigate the comparative effects of a prediction/discussion-based learning cycle (HPD-LC), conceptual change text (CCT) and traditional instruction on 10th grade students' understanding of genetics concepts. Sample: Participants were 112 10th basic grade male students in three classes of the same school located in an urban area. The three classes taught by the same biology teacher were randomly assigned as a prediction/discussion-based learning cycle class (n = 39), conceptual change text class (n = 37) and traditional class (n = 36). Design and method: A quasi-experimental research design of pre-test-post-test non-equivalent control group was adopted. Participants completed the Genetics Concept Test as pre-test-post-test, to examine the effects of instructional strategies on their genetics understanding. Pre-test scores and Test of Logical Thinking scores were used as covariates. Results: The analysis of covariance showed a statistically significant difference between the experimental and control groups in the favor of experimental groups after treatment. However, no statistically significant difference between the experimental groups (HPD-LC versus CCT instruction) was found. Conclusions: Overall, the findings of this study support the use of the prediction/discussion-based learning cycle and conceptual change text in both research and teaching. The findings may be useful for improving classroom practices in teaching science concepts and for the development of suitable materials promoting students' understanding of science.

    The purpose of this study was to examine the effects of walking exercise through a 6-min walking test on subjective dyspnea, pulmonary function test, arterial blood gas analysis, and activities of daily living to provide base data for the nursing intervention of pneumoconiosis patients. The subjects were pneumoconiosis patients men aged over 60. This quasi-experimental study was designed with a non-equivalent control group pre- and post-test design, and the study period was September to December 2013. Of the pneumoconiosis inpatient subjects, 39 were assigned to the experimental group and the 39 to the control group. Only the experimental group was subjected to a 6-min walking test three times a week for 10 weeks. Subjective dyspnea was measured based on anxiety about dyspnea during and after the exercise. FEV1% prediction and FEV1/FVC% were used to measure the pulmonary function. The arterial blood gas was measured based on the pH, PaO2, PaCO2, and activities of daily living. The data were analyzed through an χ(2) and t-test. The study results showed that the 6-min walking test reduced the anxiety about dyspnea of the pneumoconiosis patients during the exercise, moderated the dyspnea index after the performance of the activities, and improved the patients' ability to perform activities of daily living. Thus, walking exercise seems to be an effective nursing intervention to maintain the respiratory rehabilitation outcomes by minimizing the pneumoconiosis patients' burden.

    The purpose of this study was to examine attitudes of registered nurses and licensed practical nurses about the importance of the family in surgical hospital units before (T1) and after (T2) implementation of a Family Systems Nursing educational intervention based on the Calgary Family Assessment and Intervention Models. This study was part of the Landspitali University Hospital Family Nursing Implementation Project and used a nonrandomized, quasi-experimental design with nonequivalent group before and after and without a control group. There were 181 participants at T1 and 130 at T2. No difference was found in nurses' attitudes as measured by the Families Importance in Nursing Care-Nurses' Attitudes (FINC-NA) questionnaire, before and after the educational intervention. Attitudes toward families were favorable at both times. Analysis of demographic variables showed that age, work experience, and workplace (inpatient vs. outpatient units) had an effect on the nurses' attitudes toward families. The influence of work experience on attitudes toward family care warrants further exploration. © The Author(s) 2014.

    The purpose of this study was to identify the effects of a Yoga-focused prenatal program on the stress, anxiety, self confidence and labor pain of pregnant women who had in vitro fertilization (IVF) treatment. A quasi experimental study with a non-equivalent control group pretest-posttest design was used. The data collection period and meditation program were between January 9 and August 31, 2009. Forty-six women who were pregnant following IVF, and were between 12-20 weeks gestation, participated in the study (23 experimental group, 23 control group). Data were analyzed using Chi-square test, Mann-Whitney U Test, ANCOVA, and Cronbach's alpha coefficients with the SPSS 12.0 for Windows Program. Although the sample size was limited, women who participated in the program showed statistically significant improvements in stress, anxiety, labor pain, and labor confidence for women pregnant after IVF. The result indicate that this 12-week Yoga-focused educational program can be utilized for women pregnant following IVF to reduce their stress, anxiety, and labor pain, and to increase delivery confidence. It is suggested that the Yoga-focused educational program be offered to every pregnant woman.

    This study analyzed the effects of a blended learning program on medication administration by new nurses using a non-equivalent groups design. A medication education program using blended learning (including e-learning) was administered to 26 new nurses, while face-to-face instruction in the classroom was given to 24 new nurses. The following dependent variables were compared: degree of knowledge of medication, self-efficacy of medication administration, medication-administration ability, and satisfaction with the learning program. The experimental, blended learning group showed a significantly higher level of knowledge of medication and satisfaction with the comprehensiveness of their medication learning, but the self-efficacy of medication administration, medication-administration ability, and other items related to their learning satisfaction did not differ significantly from that in the control group. These results suggest that blended learning integrating e-learning and face-to-face instruction in the classroom is useful for enhancing medication knowledge. An e-learning program can reduce the lecturing time and cost of repeated topics such as medication, suggesting that it can be an effective component in nurse education programs.

    This study was conducted to test the effects of a community health promotion project for farmers cultivating garlic. Bandura's self-efficacy theory (1986) and Chaskin's community capacity framework (2001) were used as the theoretical framework. A nonequivalent control group pretest-posttest design was used. Study participants were 72 garlic farmers (intervention: 36, control: 36). The community health promotion project consisted of health promotion program and community capacity building strategies and was provided for 12 weeks (8 during farming off-season and 4 during farming season). Data were collected between February 23 and May 31, 2009 and were analyzed using chi-square test, Fisher's exact test, t-test, and repeated measure ANOVA using SPSS/WIN 12.0. For the experimental group, significant improvement was found for self-efficacy, farming related health behavior, physical fitness (muscle strength, muscle endurance, upper body flexibility, lower body flexibility, cardiovascular endurance, balance, agility), farmer's syndrome, and health related quality of life as compared to the control group. The findings of the study indicate that the community health promotion project for garlic farmers is effective and can be recommended as a nursing intervention for health promotion of garlic cultivating farmers.

    The purpose of this study was to examine the impact of strategies to promote reporting of errors on nurses' attitude to reporting errors, organizational culture related to patient safety, intention to report and reporting rate in hospital nurses. A nonequivalent control group non-synchronized design was used for this study. The program was developed and then administered to the experimental group for 12 weeks. Data were analyzed using descriptive analysis, X(2)-test, t-test, and ANCOVA with the SPSS 12.0 program. After the intervention, the experimental group showed significantly higher scores for nurses' attitude to reporting errors (experimental: 20.73 vs control: 20.52, F=5.483, p=.021) and reporting rate (experimental: 3.40 vs control: 1.33, F=1998.083, p<.001). There was no significant difference in some categories for organizational culture and intention to report. The study findings indicate that strategies that promote reporting of errors play an important role in producing positive attitudes to reporting errors and improving behavior of reporting. Further advanced strategies for reporting errors that can lead to improved patient safety should be developed and applied in a broad range of hospitals.

    Magnetization plateaus in quantum spin systems emerge in two-dimensional frustrated systems such as a kagome lattice. The spin-1/2 antiferromagnetic Heisenberg model on a square-kagome lattice is also appropriate for the study of the magnetization plateau. Motivated by recent experimental findings of such a square kagome lattice with three nonequivalent bonds, we investigate the phase diagrams and magnetization plateaus of the lattice using the exact diagonalization method. In addition to the previously reported 1/3 and 2/3 plateaus in the model with two equivalent bonds, we find a new 2/3 plateau whose magnetic structure is characterized by spontaneously broken four-fold rotational symmetry. The plateau appears only in the case of three nonequivalent bonds. We propose the possibility of finding plateaus including the new one.

    The purpose of this study was to develop and evaluate an error reporting promoting program(ERPP) to systematically reduce the incidence rate of nursing errors in operating room. A non-equivalent control group non-synchronized design was used. Twenty-six operating room nurses who were in one university hospital in Busan participated in this study. They were stratified into four groups according to their operating room experience and were allocated to the experimental and control groups using a matching method. Mann-Whitney U Test was used to analyze the differences pre and post incidence rates of nursing errors between the two groups. The incidence rate of nursing errors decreased significantly in the experimental group compared to the pre-test score from 28.4% to 15.7%. The incidence rate by domains, it decreased significantly in the 3 domains-"compliance of aseptic technique", "management of document", "environmental management" in the experimental group while it decreased in the control group which was applied ordinary error-reporting method. Error-reporting system can make possible to hold the errors in common and to learn from them. ERPP was effective to reduce the errors of recognition-related nursing activities. For the wake of more effective error-prevention, we will be better to apply effort of risk management along the whole health care system with this program.

    This study was conducted to identify the effects of newborn care education for fathers on their knowledge and confidence in newborn care at postpartum one month. A nonequivalent control group pretest posttest design was used. The participants were 53 first-time fathers of newborns, 27 in experimental group, and 26 in control group. They were recruited at the nursery of one municipal hospital in Seoul. For the experimental group, a 50-minute education on newborn care using video, verbal education, demonstration and practice were provided prior to discharge. Fathers' knowledge and confidence in newborn care and their satisfaction with the education program were measured at postpartum one month. The fathers in the experimental group showed significantly higher knowledge (t=-4.51, p<.001), and confidence in newborn care (t=-2.29, p=.026) compared to the control group at postpartum one month. Fathers in the experimental group had a satisfaction score of 27.37±2.73 immediately after the education, and 25.30±3.40 at postpartum one month. Results indicate that newborn care education for first-time fathers is an effective method in enhancing the level of knowledge and confidence in newborn care. It can be used in the nursery department before discharge as a useful nursing intervention.

    This study was conducted to evaluate the effect of a one-session spouse-support enhancement childbirth education on childbirth self-efficacy and perception of childbirth experience. The design of this study was a nonequivalent control group pretest-posttest experiment. The participants in the study were 31 couples in the experimental group and 30 in the control group. The experimental couples were provided with one session on spouse-support enhancement childbirth education the night before delivery. Data were collected at two hours after delivery using the Childbirth Self-Efficacy Inventory (CBSEI) and perception of childbirth experience scale. Data were analyzed using PASW statistics 18 program. Frequencies, percentage, mean, χ² test, t-test were used for data analysis. Childbirth self-efficacy significantly increased in the experimental group as compared to the control group, but there was no significant difference in perception of childbirth experience in the experimental group compared to the control group. The results suggest that a one-session childbirth education has beneficial effects on enhancing childbirth self-efficacy in pregnant couples. A one-session spouse-support enhancement childbirth education is recommended as an effective nursing intervention to promote couple's childbirth self-efficacy and it is also recommended that modifications of program to promote women's childbirth experience should be considered.

    Background On July 24, 2008, New York State (NYS) became the first state to require all state-funded or state-certified substance use disorder (SUD) treatment organizations to be 100% tobacco-free and offer tobacco cessation (TC) treatment. Methods The current study used a quasi-experimental, non-equivalent control group design with a pretest and posttest to examine the effect of the NYS tobacco-free regulation on three clinical practice behaviors (use of TC-related intake procedures, use of guideline recommended counseling for TC, and pharmacotherapy availability) in a diverse sample of SUD treatment programs. Repeated cross-sectional data were collected from NYS counselors (experimental group) and non-NYS counselors (control group) approximately 4 months pre-regulation (N = 282 and 659, respectively) and 10-12 months post-regulation (N = 364 and 733, respectively). Results Using mixed-effects models, results at pre-regulation indicate no group differences in the three clinical practice behaviors. However, significant post-regulation effects were found such that the experimental group reports greater use of TC-related intake procedures, guideline recommended counseling, and availability of pharmacotherapy than the control group. Additionally, the experimental but not the control group shows increases in all three clinical practice behaviors from pre-regulation to post-regulation. Conclusions We conclude that the NYS tobacco-free regulation had a significant and positive effect on promoting patient TC efforts among counselors. PMID:23428317

    The aim of this study was to investigate the effects of t'ai chi on blood serotonin levels, nicotine dependence, depression, and anger in hospitalized alcohol-dependent patients. This study followed an experimental and nonequivalent control group in a non-synchronized design. It was performed in a hospital located in Young Ju city, Korea, from April to August 2013. Thirty-eight patients who were hospitalized with alcohol dependence were included. They were randomly divided into an experimental and a control group, with 19 patients in each group. Patients in the experimental group practiced the 24-posture yang style t'ai chi for 50 min three times per week for 8 weeks as part of the routine hospital rehabilitation program, and those in the control group followed only the routine hospital rehabilitation program. The effect of treatment was measured using blood serotonin levels and a questionnaire on nicotine dependence, depression, and anger. Both measurements were performed before and after 8 weeks of intervention. Data were analyzed using the t-test, chi-square test, and paired t-tests. The experimental group showed a significantly increased blood serotonin level (p = 0.001) and significantly reduced nicotine dependence, depression, and anger (p = 0.001) than the control group did after 8 weeks of treatment. T'ai chi was shown to be an effective nursing intervention in hospitalized alcohol-dependent patients.

    This study was done to develop and evaluate a drug dosage calculation training program using cognitive loading theory based on a smartphone application. Calculation ability, dosage calculation related self-efficacy and anxiety were measured. A nonequivalent control group design was used. Smartphone application and a handout for self-study were developed and administered to the experimental group and only a handout was provided for control group. Intervention period was 4 weeks. Data were analyzed using descriptive analysis, χ²-test, t-test, and ANCOVA with the SPSS 18.0. The experimental group showed more 'self-efficacy for drug dosage calculation' than the control group (t=3.82, p<.001). Experimental group students had higher ability to perform drug dosage calculations than control group students (t=3.98, p<.001), with regard to 'metric conversion' (t=2.25, p=.027), 'table dosage calculation' (t=2.20, p=.031) and 'drop rate calculation' (t=4.60, p<.001). There was no difference in improvement in 'anxiety for drug dosage calculation'. Mean satisfaction score for the program was 86.1. These results indicate that this drug dosage calculation training program using smartphone application is effective in improving dosage calculation related self-efficacy and calculation ability. Further study should be done to develop additional interventions for reducing anxiety.

    The aim of this research was to explore the effects of three different types of methods of learning physics (conceptual change-based, real life context-based and traditional learning) on high school physics students in the 11th grade in terms of conceptual change they achieved in learning about the various topics (pressure exerted by solids, pressure in stagnant liquids and gases, buoyancy, Bernoulli’s principle). In this study, a pre-test/post-test quasi-experimental method with nonequivalent control group, involving a 3 (group) × 2 (time) factorial design was used. Study group 1 were given the conceptual change texts on the mentioned subjects, study group 2 were offered a teaching approach based on real life context-based learning, whereas the control group was taught in the traditional style. Data for the research were collected with the ‘pressure conceptual test’. As a result of research, the number of misconceptions had been reduced or shifted altogether in all three groups. After the instruction, it was seen that none of the students formed new misconceptions. It was found that the most positive change could be seen in the conceptual change text group followed by context-based and lastly traditional. The fact that none of the students formed new misconceptions is important, particularly since research such as the following shows that conceptual change is tenuous and inconsistent, taking time to shift in a sustained manner.

    This quasi-experimental study examined the effects of a new breastfeeding empowerment programme provided to post-partum mothers within 3 days of entering post-partum care centres on their breastfeeding empowerment, problems and practice rate. The study employed a non-equivalent control group non-synchronized design. Participants who conformed with the selection criteria were selected from two post-partum care centres affiliated with hospitals in a city in South Korea. Each of the two study groups included 30 participants. The breastfeeding empowerment programme comprised four 60-minute sessions, and was applied for 4 weeks to mothers in the experimental group. The breastfeeding empowerment scores were higher in the experimental group than in the control group (p=0.007), and there were fewer breastfeeding problems in the former group (p=0.012) and the breastfeeding rates were higher in the former group (p=0.017, 0.002 and 0.002 at 4, 8 and 12 weeks post-partum, respectively). These results indicate that the provision of breastfeeding empowerment programmes to help mothers to identify and solve problems by themselves can improve breastfeeding empowerment, problem and practice rates, and hence should be considered useful as a post-partum nursing intervention in clinical settings. The effectiveness of the various components of the breastfeeding empowerment programme developed in this study should be verified in field trials.

    Previous research has supported mindfulness-based interventions (MBIs) to enhance quality of life (QOL) in different populations, but no studies have been found to examine the effectiveness of MBIs on QOL among parents of children with ASD. The purpose of the current study was to examine the effectiveness of brief MBI on perceived QOL and positive stress reappraisal (PSR) among parents of children with ASD. A quasi-experimental, with nonequivalent control group design was used. One hundred and four parents of children with ASD were equally assigned to the intervention and control groups. The study groups were matched on measures of their gender and age, and level of severity of ASD in children. The intervention group participated in MBI program for 5 weeks, while the control group had not attended the program. After the intervention program, results of paired samples t-test indicated that parents in the intervention group demonstrated significant improvements in measures of psychological health domain of QOL, social health domain of QOL, mindfulness, and positive stress reappraisal with medium to large effect size (P<0.01). The control group demonstrated improvement in measures of the dependent variables with small effect size. MBI is culturally adaptable, acceptable, and effective method to improve QOL and PSR in parents of children with ASD. Copyright © 2016 Elsevier Ltd. All rights reserved.

    This study was done to identify the effects of a Human Papillomavirus (HPV) linked to cervix cancer prevention education program for unmarried university female students. A new model in the cervix cancer prevention is provided. The research design was a nonequivalent control group pretest-posttest design. Participants were 63 female students in one of two university in an experimental group (29 students) and control group (34 students). After 4 weeks education, the differences between the two groups in the measurement variables were compared. Twelve weeks later, a follow-up test was done for experimental group only. After the education, experimental group showed significantly higher scores in all variables, the intention for Pap test (Z=-3.73, p<.001), intention for HPV vaccination (Z=-3.14, p=.002), general cancer prevention behavior (Z=-2.20, p=.028), attitudes to Pap (Z=-3.23, p=.001), benefits of cancer prevention behavior (Z=-3.97, p<.001), and HPV linked to cervix cancer knowledge (Z=-5.40, p<.001). In the follow-up study, the experimental group showed intermediate effects in intention for Pap test, intention of HPV vaccination and HPV linked to cervix cancer knowledge as well as short term effects in general cancer prevention behavior, attitudes to Pap and benefits of cancer prevention behavior. The program developed for this study on prevention education of HPV linked to cervix cancer was effective for unmarried university students in the short term and intermediate duration. Other educational approaches should be developed and short term effects and longitudinal changes of the education should be assessed. This education program should also be replicated for other female groups including unmarried working women or female adolescents.

    Recently researchers have demonstrated ultra high quality factor (Q) resonances in one-dimensional (1D) dielectric gratings. Here we theoretically investigate a new class of subwavelength 1D gratings, namely “diatomic” gratings with two nonequivalent subcells in one period, and utilize their intrinsic dark modes to achieve robust ultra high Q resonances. Such “diatomic” gratings provide extra design flexibility, and enable high Q resonators using thinner geometry with smaller filling factors compared to conventional designs like the high contrast gratings (HCGs). More importantly, we show that these high Q resonances can be efficiently tuned in situ, making the design appealing in various applicationsmore » including optical sensing, filtering and displays.« less

    Advocates of the project method claim that project-based learning inspires student learning. However, it has been claimed that project-based learning environments demand quite a bit of self-regulation on the part of the learner. Consequently, it was tested whether students scoring low in self-regulation of learning experienced 'friction', an incompatibility between student self-regulation and the demands posed by the learning environment. This would be manifest in cognitive processing and motivation. The target group consisted of 58 mainly third-year Finnish university students taking a mandatory project course in information systems design. During the project course, student teams completed a commissioned assignment. The study also included a matched nonequivalent comparison group composed of computer science students attending study programmes without a project-based component. Data were gathered by means of a questionnaire administered at the beginning and end of the project course and it was analysed by between-groups repeated measures ANOVA. In addition, the students on the course were interviewed. Results suggest that the work-based project model in question may indeed have a substantial motivational impact, interestingly benefitting especially those students who scored low in self-regulation. It is argued that we tend to view learning environments too simplistically. In particular, a basic distinction should be made between individual and collaborative learning contexts, since peer scaffolding, group grading and choice of group roles may explain why students scoring low in self-regulation of learning did not encounter friction as expected.

    Type 2 diabetes is one of the most widespread diseases in the world. The main aim of this research was to evaluate the effect of combined therapy using acupressure therapy, hypnotherapy, and transcendental meditation (TM) on the blood sugar (BS) level in comparison with placebo in type 2 diabetic patients. We used "convenience sampling" for selection of patients with type 2 diabetes; 20 patients were recruited. For collection of data, we used an identical quasi-experimental design called "nonequivalent control group." Therapy sessions each lasting 60-90 min were carried out on 10 successive days. We prescribed 2 capsules (containing 3g of wheat flour each) for each member of the placebo group (one for evening and one for morning). Pre-tests, post-tests, and follow-up tests were conducted in a medical laboratory recognized by the Ministry of Health and Medical Education of Iran. Mean BS level in the post-tests and follow-up tests for the experimental group was reduced significantly in comparison with the pre-tests whereas in the placebo group no changes were observed. Combined therapy including acupressure therapy, hypnotherapy, and TM reduced BS of type 2 diabetic patients and was more effective than placebo therapy on this parameter. Copyright © 2011.

    The purpose of this study was to examine the effects of a violence coping program (VCP) based on Polk's middle-range theory of resilience on nursing competency, resilience, burnout, and the ability to cope with violence in nurses working in emergency rooms. A quasi-experimental study, with a nonequivalent control group and a pretest-posttest design, was conducted. Participants were 36 nurses who worked in emergency rooms and had experienced violence; 18 nurses from D hospital and 18 nurses from C hospital were assigned to the experimental and control groups, respectively. The experimental group received the VCP twice per week for 8 weeks. Levels of resilience, F=59.41, p<.001, active coping behavior, χ²=33.09, p<.001, and nursing competency, F=59.41 p<.001, increased significantly and levels of passive coping behavior, χ²=22.92, p<.001, and burnout, F=52.74, p<.001, decreased significantly in the experimental group. The results suggest that the VCP could be an effective strategy for reducing burnout and improving resilience, active coping behavior, and nursing competency. Therefore, it would be a useful intervention for improving the quality of nursing care provided in emergency rooms. © 2017 Korean Society of Nursing Science

    To describe (1) the content of a transition programme for young people with juvenile idiopathic arthritis (JIA) designed as a brief intervention, (2) the rationale and design of a mixed-methods study evaluating the clinical impact of this transition programme and (3) to provide baseline data of the intervention group. An 'embedded experimental' design is used for the evaluation of the transition programme. A 'one-group pretest-posttest, with a non-equivalent posttest-only comparison group design' is used to quantitatively evaluate the impact of the transition programme, applying both longitudinal and comparative analyses. Subsequently, experiences of adolescents and their parents who participated in the experimental group will be analysed qualitatively using content analysis. Participants in the intervention are recruited at a tertiary care centre in Belgium. The comparison group participants are recruited from one tertiary and three secondary care centres in Belgium. The intervention group consists of 33 young people (25 females; 8 males) with a median age of 16 years. Main diagnoses are persistent or extended oligoarticular JIA (33%), polyarticular JIA (30%), enthesitis-related JIA (21%) or systemic arthritis (15%). The transition programme comprises eight key components: (1) transition coordinator; (2) providing information and education; (3) availability by telephone; (4) information about and contact with an adult care programme; (5) guidance of parents; (6) meeting with peers; (7) transfer plan; and (8) actual transfer to adult care. The primary outcome is health status, as perceived by the adolescents. Secondary outcomes are health status, as perceived by the parents; medication adherence; illness-related knowledge; quality of life; fatigue; promotion of independence; support of autonomy; behavioural control and psychological control. At baseline, the median score was 69.2 (Q1=60.0;Q3=92.9) on psychosocial health and 68.8 (Q1=56.3; Q3=89.1) on physical health. Rheumatic-specific health scores ranged from 62.5 to 100. We present the rationale and design of a study intended to evaluate a transition programme for adolescents with JIA as a brief intervention.

    The purpose of this study was to develop a self-management program applying Dongsasub training based on self-efficacy theory, and to verify the program effectiveness on self-esteem as well as self-efficacy, self-management behaviors, and blood pressure. The study design was a non-equivalent, pre-post controlled quasi-experiment study. Thirty-eight patients aged 65 and older from a senior welfare center in Seoul participated in this study (20 patients in the experimental group and 18 patients in the control group). The self-management program applying Dongsasub training consisted of eight sessions. After development was complete the program was used with the experimental group. Outcome variables included self-efficacy, self-esteem, self-management behaviors measured by questionnaires, and blood pressure measured by electronic manometer. Self-efficacy (t=2.42, p=.021), self-esteem (t=2.57, p=.014) and self-management behaviors (t=2.21, p=.034) were significantly higher and systolic blood pressure (t=-2.14, p=.040) was significantly lower in the experimental group compared to the control group. However, diastolic blood pressure (t=-.85, p=.400) was not significantly different between the two groups. The results indicate that the self-management program applying Dongsasub training can be used as a nursing intervention in community settings for improving self-management behaviors for older adults with hypertension.

    [Purpose] The effectiveness of a smartphone pedometer application was compared with that of a traditional pedometer for improving the physical activity and weight status of community-dwelling older adults. [Subjects and Methods] This study had a nonequivalent pretest-posttest control group design. Ninety-seven older adults (mean age ± SD, 60.1 ± 5.5 years) joined the smartphone pedometer group and underwent a 2-week walking intervention based on a smartphone pedometer application. Fifty-four older adults (mean age ± SD, 65.3 ± 8.7 years) joined the traditional pedometer group and underwent a 2-week walking intervention based on a traditional pedometer. The participants’ physical activity was evaluated using the International Physical Activity Questionnaire–Short Form, and their weight status was quantified by calculating the body mass index. The daily pedometer count was also documented. [Results] No significant time, group, or time-by-group interaction effects were found for any of the outcome variables. However, trends of improvement in physical activity and body mass index were seen only in the smartphone pedometer group. [Conclusion] A smartphone pedometer application might be more favorable than a traditional pedometer in improving physical activity and body mass index in community-dwelling older adults. However, further experimental studies are necessary to confirm the results. PMID:27313391

    This study was conducted to develop a program to help emergency nurses overcome compassion fatigue, and to analyze the effects of the program. A nonequivalent control group pretest-posttest design was used. There were 14 participants in the experimental group and 18 subjects in the control group. The program was comprised of five, weekly 80-minute sessions including understanding and assessment of compassion fatigue, enhancing positive affect, balancing work-life, planning self care, training in relaxation techniques and cognitive restructuring, and getting social support. Research variables were ego-resiliency, compassion satisfaction and compassion fatigue of the ProQOL 5, and salivary cortisol. Data were analyzed using Chi-square test, independent t-test, and paired t-test. The first hypothesis, "There will be a difference in scores for ego resiliency between the experimental group and the control group". was not supported. The second hypothesis, "There will be a difference in scores for compassion satisfaction between the experimental group and the control group" was supported (t=2.15, p=.046). The third hypothesis, "There will be a difference in scores for compassion fatigue between the experimental group and the control group" was not supported. The first program for emergency nurses to overcome compassion fatigue in Korea was effective in increasing emergency nurses' compassion satisfaction and decreasing salivary cortisol level in the experimental group. Therefore, this program for overcoming compassion fatigue is useful to increase emergency nurses' compassion satisfaction. However replication studies of short-term intensive program reflecting emergency nurses' opinion are needed.

  16. Neutron diffraction studies of some rare earth-transition metal deuterides

    Neutron diffraction studies of the ternary alloy system Y6(Fel-xMnx)23 reveal that the unusual magnetic behavior upon substitution of Mn or Fe into the end members, is a consequence of atomic ordering wherein there is strong site preference of Mn for the f sub 2 sites and of Fe for the f sub 1 sites. In the Mn-rich compositions, Fe is found to have no spontaneous moments. Therefore, the long range magnetic ordering arises solely from Mn-Mn interactions. Upon substitution of Mn into the Fe-rich ternaries, the Fe moments are considerably reduced. Neutron diffraction studies of Y6Mn23D23 show that a transition occurs below 180K from a fcc structure to a primitive tetragonal structure, space group P4/mmm with the onset of antiferromagnetic ordering. The Mn moments are directed along the c-axis. The transition probably results from atomic ordering of the D atoms at low temperature which induces c axis magnetic ordering. The question of the appropriate space group of LaNi4.5Al0.5D4.5, P6/mmm or P3/m has been resolved by a careful refinement and analysis of neutron diffraction data. The preferred space group is P6/mmm. Neutron powder diffraction and thermal magnetization measurements on small single crystals of ErNi3, ErCo3, and ErFe3 (space group R3m) show that the magnetocrystalline properties are a consequence of competing local site anisotropies between the two non-equivalent crystallographic sites of Er and two of the three non-equivalent sites of the 3d-transition metal.

    A large literature emphasizes the importance of testing for measurement equivalence in scales that may be used as observed variables in structural equation modeling applications. When the same construct is measured across more than one developmental period, as in a longitudinal study, it can be especially critical to establish measurement equivalence, or invariance, across the developmental periods. Similarly, when data from more than one study are combined into a single analysis, it is again important to assess measurement equivalence across the data sources. Yet, how to incorporate non-equivalence when it is discovered is not well described for applied researchers. Here, we present an item response theory approach that can be used to create scale scores from measures while explicitly accounting for non-equivalence. We demonstrate these methods in the context of a latent curve analysis in which data from two separate studies are combined to create a single longitudinal model spanning several developmental periods.

    This study aimed to identify the effects of smartphone-based nebulizer therapy education on the knowledge and confidence of parents while performing care for their children with respiratory disease. This quasi-experimental study employed a pretest-posttest design using a nonequivalent control group. Data were collected from children's parents who had not used nebulizer therapy for their children previously. Both the groups were given nebulizer therapy education using the same content but different learning methods. The experimental group (n=36) was taught using smartphones, while the control group (n=36) was taught using verbal and paper-based methods. The data were analyzed using the Chi Square test, repeated measures analysis of variance, and t-test. The mean scores on knowledge improvement (F=100.949, p<0.001) and confidence in performing care (t=-6.959, p<0.001) were significantly higher for the experimental group as compared to the control group. Further, the scores on satisfaction with the learning method were significantly higher for the experimental group as compared to the control group (t=-5.819, p<0.001). Our results suggest that smartphone-based education on nebulizer therapy might be effective in improving parents' knowledge and confidence in performing care for their children. This study suggests that smartphone-based education needs to be considered as an effective educational intervention in providing nursing support for parents of children with respiratory disease.

    Since a history of stroke or transient ischaemic attack is a major risk factor for a recurrent event, lifestyle counselling during the hospital phase is an essential component of treatment and may increase the probability of lifestyle change. To study the effect of risk factor-targeted lifestyle counselling intervention on working-age stroke patients' adherence to lifestyle changes. A quasi-experimental, nonequivalent control group pretest-post-test design. Stroke patients in an acute neurological unit were divided into a control group (n = 75) receiving standard counselling and an experimental group (n = 75) receiving risk factor-targeted counselling. Lifestyle data and clinical outcomes were collected at hospital between January 2010 and October 2011, while data on adherence to lifestyle changes 3, 6, and 12 months after discharge. The baseline lifestyle habits did not differ significantly other than in alcohol behaviour. Both groups increased their intake, but the intervention group to a lesser degree. However, the experimental group significantly lost their weight for the first 3 and 6 months; at 3 months reduction in cigarette consumption and at 6 months significant increases in smoking cessation were also achieved. All improved some of their lifestyle habits. Intervention was associated with support from nurses as well as from family and friends. Adherence scores were higher in the experimental group. Some short-term advantages in lifestyle habits due to the intervention were noted. Participants in both groups improved some of their lifestyle habits. © 2016 Nordic College of Caring Science.

    Supine recumbence has been widely performed to prevent post-lumbar puncture headache (PLPH). However, the optimal duration of supine recumbence is controversial. The aim of the study is to compare the occurrence of PLPH according to the duration of supine recumbence in patients with neurological disorders. A non-equivalent control/experimental pre-/post-test study design was used. Seventy consecutive patients were prospectively enrolled between July 2007 and July 2008. Thirty-five patients underwent supine recumbence for four hours after lumbar puncture (Group 1) and 35 patients underwent supine recumbence for one hour (Group 2). The overall frequency of PLPH was 31.4%. The frequency of PLPH was not significantly different between the Group 1 (28.6%) and Group 2 (34.3%) (P = 0.607). In patients with PLPH, the median severity (P = 0.203) and median onset time of PLPH (P = 0.582) were not significantly different between the two groups. In a logistic regression analysis, the previous history of post-lumbar puncture headache was a significant risk factor for the occurrence of PLPH (OR = 11.250, 95% CI: 1.10-114.369, P = 0.041). Our study suggests that short duration (one hour) of supine recumbence may be as efficient as long duration (four hours) of supine recumbence to prevent PLPH.

    The purpose of the study was to investigate the effects of an integrated self-management program on self-management, glycemic control, and maternal identity in women with gestational diabetes mellitus (GDM). A non-equivalent control group non-synchronized quasi-experimental design was used. A total of 55 women with GDM were recruited from Cheil General Hospital, Seoul, Korea and were assigned to an experimental (n=28) or control group (n=27). The participants were 24-30 weeks pregnant women who had been diagnosed with GDM as of July 30, 2010. The program was conducted as a 1 hour small group meeting 3 out of 5 times and by telephone-counseling 2 out of 5 times. The integrated self-management program was verified by an expert panel. Although there was no significant reduction in HbA1c (U= -1.17, p=.238), there were statistically significant increases in self-management (U= -3.80, p<.001) and maternal identity (U= -4.48, p<.001), and decreased 2-h postprandial glucose levels (U= -2.43, p<.015) in the experimental group compared to the control group. These findings suggest that an integrated self-management program for women with GDM improves self-management, maternal identity, and glycemic control. Further studies are needed to identify the effects of an integrated self-management program on pregnancy and neonatal outcomes.

    Stress is common in junior secondary school students (JSSS). This study aimed to determine the feasibility and effectiveness of a Chen-style Tai Chi programme for stress reduction in JSSS. A non-equivalent pre-test/post-test control group design was adopted, and a convenience sample of 69 JSSS was recruited. The experimental group (n = 32) joined a Chen-style Tai Chi programme, which included 10 sessions of 80-minute Tai Chi training (one session per week). The control group (n = 37) proceeded with self-study. Participants' stress levels were assessed using the Perceived Stress Scale. Feasibility was determined as the percentage of participants completing and attending the programme. Effectiveness was measured as the significant difference in changes in stress levels before and after the intervention between the two groups. Results preliminarily supported that the programme was feasible for JSSS. Completion rate was 100%, and attendance rate was 90%. However, no significant difference was noted in changes in stress levels before and after the intervention between the two groups. The potential health benefits of Tai Chi could not be detected owing to the restrictions imposed by the research setting and study limitations. The present study represents initial efforts in this direction and serves as reference for future study. Copyright © 2012 John Wiley & Sons, Ltd.

    Traditional lecture-based learning (LBL) can increase cancer awareness in undergraduates. However, because of the rapidly changing knowledge base in medicine, undergraduates must develop skills required for lifelong self-directed learning (SDL). Problem-based learning (PBL) has been suggested as an SDL approach. This study used a nonequivalent control group with a pretest-posttest design for comparing PBL and LBL for their effectiveness in increasing cancer awareness and SDL among nonmedicine or nonnursing major undergraduates in a health-related general education course. Experimental groups 1 and 2 were instructed using PBL while the control group was instructed using LBL. Cancer educational programs were offered to experimental group 1 and the control group but not to experimental group 2. Among the 325 undergraduates who completed a questionnaire regarding cancer awareness and SDL in the pretest, 223 completed the 12-week follow-up survey of the posttest. Cancer awareness significantly improved between the pretest and posttest in the control group (P < 0.001). No significant difference in cancer awareness improvement was observed between experimental group 1 and the control group (P = 0.934). Cancer awareness improvement in experimental group 2 was significantly less than in the control group (P = 0.010). No statistically significant change in SDL was observed in the control group during the study (P = 0.897). However, the SDL of experimental groups 1 and 2 improved more significantly than that of the control group (P = 0.049 and 0.023, respectively). Therefore, PBL is an effective method of increasing cancer awareness and SDL in undergraduates.

    A protocol for a new peer-led self-management programme for community-dwelling older people with diabetes in Shanghai, China. The increasing prevalence of type 2 diabetes poses major public health challenges. Appropriate education programmes could help people with diabetes to achieve self-management and better health outcomes. Providing education programmes to the fast growing number of people with diabetes present a real challenge to Chinese healthcare system, which is strained for personnel and funding shortages. Empirical literature and expert opinions suggest that peer education programmes are promising. Quasi-experimental. This study is a non-equivalent control group design (protocol approved in January, 2008). A total of 190 people, with 95 participants in each group, will be recruited from two different, but similar, communities. The programme, based on Social Cognitive Theory, will consist of basic diabetes instruction and social support and self-efficacy enhancing group activities. Basic diabetes instruction sessions will be delivered by health professionals, whereas social support and self-efficacy enhancing group activities will be led by peer leaders. Outcome variables include: self-efficacy, social support, self-management behaviours, depressive status, quality of life and healthcare utilization, which will be measured at baseline, 4 and 12 weeks. This theory-based programme tailored to Chinese patients has potential for improving diabetes self-management and subsequent health outcomes. In addition, the delivery mode, through involvement of peer leaders and existing community networks, is especially promising considering healthcare resource shortage in China. © 2012 Blackwell Publishing Ltd.

    This study attempted to determine if there was a difference between the laboratory achievement of students who used a modified reporting method and those who used traditional laboratory reporting. The study also determined the relationships between laboratory performance scores and the independent variables score on the Group Assessment of Logical Thinking (GALT) test, chronological age in months, gender, and ethnicity for each of the treatment groups. The study was conducted using 113 high school students who were enrolled in first-year general chemistry classes at Pueblo South High School in Colorado. The research design used was the quasi-experimental Nonequivalent Control Group Design. The statistical treatment consisted of the Multiple Regression Analysis and the Analysis of Covariance. Based on the GALT, students in the two groups were generally in the concrete and transitional stages of the Piagetian cognitive levels. The findings of the study revealed that the traditional and the modified methods of laboratory reporting did not have any effect on the laboratory performance outcome of the subjects. However, the students who used the traditional method of reporting showed a higher laboratory performance score when evaluation was conducted using the New Standards rubric recommended by the state. Multiple Regression Analysis revealed that there was a significant relationship between the criterion variable student laboratory performance outcome of individuals who employed traditional laboratory reporting methods and the composite set of predictor variables. On the contrary, there was no significant relationship between the criterion variable student laboratory performance outcome of individuals who employed modified laboratory reporting methods and the composite set of predictor variables.

    This study evaluated the impact of a community-based oral health promotion programme on the use of oral health services, oral health knowledge, attitudes, and practices of older Greek and Italian adults attending community clubs and living in Melbourne, Australia. The oral health promotion intervention consisted of three components: a series of oral health seminars, held at the clubs in the participants' native languages, the provision of oral health care products, and the production of oral health information sheets. The intervention programme was known as the Oral Health Information Seminars/Sheets (ORHIS). The content of each session was determined following suggestions and findings from the data collected. A pre-test-post-test non-equivalent control group quasi-experimental design was chosen to evaluate the intervention. A total of 520 independent-living older adults, members of Greek or Italian social clubs participated in this evaluation. Participants who took part in the intervention responded with higher levels of achievement than those in the control groups. After controlling for baseline variables, experimental groups were significantly more likely than the control groups at post-test to have improved oral health attitudes, oral health knowledge, and self-assessed physical health status, as well as, self-reported oral hygiene practices and use of oral health services. The ORHIS approach was successful within the setting of social clubs, and highly acceptable to these communities. As such, it represents a helpful approach for the design of (oral) health interventions in older adults. Further research is required to test the long-tem impact including the economic evaluation of the ORHIS approach.

    Pb2Cu(OH)2I3 is a new type of halocuprate(I) that is a framework of alternating [Pb4(OH)4]4+ and [Cu2I6]4- units. The structure has been determined in orthorhombic space group Fddd to R1=0.037, wR2=0.057, GoF=1.016. Unit cell parameters are a=16.7082(9) Å, b=20.8465(15) Å, c=21.0159(14) Å, V=7320.0(8) Å3 (Z=32). There is no synthetic counterpart. The structure is based upon a cubane-like Pb4(OH)4 nucleus that is coordinated to sixteen iodide ions. Cu+ ions are inserted into pairs of adjacent edge-sharing tetrahedral sites in the iodide motif to form [Cu2I6]4- groups. The Raman spectrum of Pb2Cu(OH)2I3 has two O-H stretching modes and as such is consistent with space group Fddd, with two non-equivalent OH groups, rather than the related space group I41/acd which has only one non-equivalent OH group. Consideration of the 18-electron rule implies that there is a Cu=Cu double bond, which may be consistent with the short Cu…Cu distance of 2.78 Å, although the dearth of published data on the interpretation of Cu…Cu distances in halocuprate(I) compounds does not allow a clear-cut interpretation of this interatomic distance. The orthorhombic structure is compared with that of the synthetic halocuprate(I) compound Pb2Cu(OH)2BrI2 with space group I41/acd and having chains of corner-linked CuI4 tetrahedra rather than isolated Cu2I6 pairs. The paired motif found in Pb2Cu(OH)2I3 cannot be achieved in space group I41/acd and, conversely, the chain motif cannot be achieved in space group Fddd. As such, the space group defines either a chain or an isolated-pair motif. The existence of Pb2Cu(OH)2I3 suggests a new class of inorganic halocuprate(I)s based upon the Pb4(OH)4 group.

    Bożejko, Marek; Guţă, Mădălin

    The characters of the infinite symmetric group are extended to multiplicative positive definite functions on pair partitions by using an explicit representation due to Veršik and Kerov. The von Neumann algebra generated by the fields with f in an infinite dimensional real Hilbert space is infinite and the vacuum vector is not separating. For a family depending on an integer N< - 1 an ``exclusion principle'' is found allowing at most ``identical particles'' on the same state: The algebras are type factors. Functors of white noise are constructed and proved to be non-equivalent for different values of N.

    Experiential learning model using simple physics kit has been implemented to get a picture of improving attitude toward physics senior high school students on Fluid. This study aims to obtain a description of the increase attitudes toward physics senior high school students. The research method used was quasi experiment with non-equivalent pretest -posttest control group design. Two class of tenth grade were involved in this research 28, 26 students respectively experiment class and control class. Increased Attitude toward physics of senior high school students is calculated using an attitude scale consisting of 18 questions. Based on the experimental class test average of 86.5% with the criteria of almost all students there is an increase and in the control class of 53.75% with the criteria of half students. This result shows that the influence of experiential learning model using simple physics kit can improve attitude toward physics compared to experiential learning without using simple physics kit.

    The research aims to investigate the differences in enhancement of students’ mathematical creative thinking ability of those who received problem posing approach assisted by manipulative media and students who received problem posing approach without manipulative media. This study was a quasi experimental research with non-equivalent control group design. Population of this research was third-grade students of a primary school in Bandung city in 2016/2017 academic year. Sample of this research was two classes as experiment class and control class. The instrument used is a test of mathematical creative thinking ability. Based on the results of the research, it is known that the enhancement of the students’ mathematical creative thinking ability of those who received problem posing approach with manipulative media aid is higher than the ability of those who received problem posing approach without manipulative media aid. Students who get learning problem posing learning accustomed in arranging mathematical sentence become matter of story so it can facilitate students to comprehend about story

    This study examined whether adopting a standardized prenatal substance use protocol (protocol) in a hospital labor and delivery unit reduced racial disparities in reporting to child protective services (CPS) related to maternal drug use during pregnancy. This study used an interrupted time series design with a non-equivalent control. One hospital adopted a protocol and another hospital group serving a similar geographic population did not change protocols. Data on CPS reporting disparities from these hospitals over 3.5 years were analyzed using segmented regression. In the hospital that adopted the protocol, almost five times more black than white newborns were reported during the study period. Adopting the protocol was not associated with reduced disparities. Adopting a protocol cannot be assumed to reduce CPS reporting disparities. Efforts to encourage hospitals to adopt protocols as a strategy to reduce disparities may be misguided. Other strategies to reduce disparities are needed.

    We report a cross-sectional study comparing the health-related quality of life (HRQOL) of individuals residing in the proximity of a wind farm to those residing in a demographically matched area sufficiently displaced from wind turbines. The study employed a nonequivalent comparison group posttest-only design. Self-administered questionnaires, which included the brief version of the World Health Organization quality of life scale, were delivered to residents in two adjacent areas in semirural New Zealand. Participants were also asked to identify annoying noises, indicate their degree of noise sensitivity, and rate amenity. Statistically significant differences were noted in some HRQOL domain scores, with residents living within 2 km of a turbine installation reporting lower overall quality of life, physical quality of life, and environmental quality of life. Those exposed to turbine noise also reported significantly lower sleep quality, and rated their environment as less restful. Our data suggest that wind farm noise can negatively impact facets of HRQOL.

    Overweight and obesity are major health risk factors in people with intellectual disabilities. The aim of this study was to test the effectiveness of a multicomponent programme (physical activity, diet and motivation) for overweight and obesity in adults with intellectual disabilities. A quasi-experimental design with repeated-measures and non-equivalent control group (n = 33, n = 31) was used. The programme was conducted over 17 weeks, with follow-up at 6 months in a sample of Spanish adults with a mild and moderate intellectual disability from a community occupational day centre, aged from 23 to 50, 40.6% of which were women. A significant reduction in weight and diastolic blood pressure was obtained over time, and this reduction was maintained in the follow-up for weight. Reduction in heart rate was only marginally significant. The treatment was effective in reducing overweight and obesity, improving cardiovascular capacity and therefore the physical health of the participants. © 2015 John Wiley & Sons Ltd.

    This paper describes an evaluation of possible changes in sexual behavior in adolescents who participated in a school-based sex education program in selected public schools in four municipalities in the state of Minas Gerais, Brazil. The program is inserted within the context of reproductive rights, deals with risks involved in unsafe sexual practices and focuses on the positive aspects of sexuality. A quasi-experimental design with pre and post-tests and a non-equivalent control group was used to evaluate the intervention. A total of 4,795 questionnaires were included in this analysis. The program succeeded in more than doubling consistent condom use with casual partners and in increasing the use of modern contraceptives during last intercourse by 68%. The intervention had no effect on age at first intercourse or on adolescents' engagement in sexual activities. The sex education program was effective in generating positive changes in the sexual behavior of adolescents, while not stimulating participation in sexual activities.

    To examine the effects of high-fidelity patient simulation (HFPS) led clinical reasoning course among undergraduate nursing students. A quasi-experimental study of non-equivalent control group pretest-post test design was applied. A total of 49 senior nursing students participated in this study. The experimental group consisted of the students who took the "clinical reasoning" course (n = 23) while the control group consisted of students who did not (n = 26). Self-administered scales including the nursing core competencies, problem solving, academic self-efficacy, and Kolb learning style inventory were analyzed quantitatively using SPSS version 20.0. Data analysis was conducted using one-way ancova due to a significant difference in nursing core competencies between the experimental group and control group. There was a significant improvement in nursing core competencies in the experimental group (F = 7.747, P = 0.008). The scores of problem solving and academic self-efficacy were higher in the experimental group after the HFPS led clinical reasoning course without statistical difference. There is a need for the development of effective instructional methods to improve learning outcomes in nursing education. Future research is needed related to simulation education as well as management strategies so that learning outcomes can be achieved within different students' learning style. © 2015 The Authors.

    This study was conducted to develop an Empowerment Education Program (EEP) for kidney transplant patients and to test the program's effects on uncertainty, self-care ability, and compliance. The research was conducted using a nonequivalent control group with a pretest-posttest design. The participants were 53 outpatients (experimental group: 25, control group: 28) who were receiving hospital treatment after kidney transplants. After the pre-test, patients in the experimental group underwent a weekly EEP for six weeks. The post-test was conducted immediately after, and four weeks after the program's completion in the same manner as the pre-test. For the control group, we conducted a post-test six and ten weeks after the pre-test, without and program intervention. A repeated measure ANOVA was performed to compare the change scores on main outcomes. Uncertainty was significantly lower in the experimental group than in the control group, both immediately after (t=-3.84, p=<.001) and 4 weeks after (t=-4.51 p=<.001) the program, whereas self-care ability (t=5.81, p=<.001), (t=5.84, p=<.001) and compliance (t=5.07, p=<.001), (t=5.45, p=<.001) were significantly higher. Kidney transplant patients who underwent an EEP showed a decrease in uncertainty and an improvement in self-care ability and compliance. Thus, our findings confirmed that an EEP can be an independent intervention method for improving and maintaining the health of kidney transplant patients. © 2017 Korean Society of Nursing Science

    2013-09-01

    On July 24, 2008, New York State (NYS) became the first state to require all state-funded or state-certified substance use disorder (SUD) treatment organizations to be 100% tobacco-free and offer tobacco cessation (TC) treatment. The current study used a quasi-experimental, non-equivalent control group design with a pretest and posttest to examine the effect of the NYS tobacco-free regulation on three clinical practice behaviors (use of TC-related intake procedures, use of guideline recommended counseling for TC, and pharmacotherapy availability) in a diverse sample of SUD treatment programs. Repeated cross-sectional data were collected from NYS counselors (experimental group) and non-NYS counselors (control group) approximately 4 months pre-regulation (N=282 and 659, respectively) and 10-12 months post-regulation (N=364 and 733, respectively). Using mixed-effects models, results at pre-regulation indicate no group differences in the three clinical practice behaviors. However, significant post-regulation effects were found such that the experimental group reports greater use of TC-related intake procedures, guideline recommended counseling, and availability of pharmacotherapy than the control group. Additionally, the experimental but not the control group shows increases in all three clinical practice behaviors from pre-regulation to post-regulation. We conclude that the NYS tobacco-free regulation had a significant and positive effect on promoting patient TC efforts among counselors. Copyright © 2013 Elsevier Ireland Ltd. All rights reserved.

  19. The effect of self-regulatory and metacognitive strategy instruction on impoverished students' assessment achievement in physics

    Fouche, Jaunine

    The purpose of this nonequivalent control group design study was to evaluate the effectiveness of metacognitive and self-regulatory strategy use on the assessment achievement of 215 9th-grade, residential physics students from low socioeconomic status (low-SES) backgrounds. Students from low-SES backgrounds often lack the self-regulatory habits and metacognitive strategies to improve academic performance. In an effort to increase these scores and to increase student self-regulation and metacognition with regard to achievement in physics, this study investigated the use of metacognitive and self-regulatory strategies specifically as they apply to students' use of their own assessment data. Traditionally, student performance data is used by adults to inform instructional and curricular decisions. However, students are rarely given or asked to evaluate their own performance data. Moreover, students are not shown how to use this data to plan for or inform their own learning. It was found that students in the overall and algebra-ready treatment groups performed significantly better than their control group peers. These results are favorable for inclusion of strategies involving self-regulation and metacognition in secondary physics classrooms. Although these results may be applicable across residential, impoverished populations, further research is needed with non-residential populations.

    The purpose of this study was to investigate the effects of assertiveness training on nurses' assertive behaviors, interpersonal relations, communication conflicts, conflict management style and personnel turnover rate. A non-equivalent control group pretest-posttest design was used in this study. Nurses were assigned into the experimental or control groups, each consisting of 39 nurses. Data was collected between January to March 2004. An 'Assertiveness Training Program' for Nurses developed by Park was used for the study. To emphasize assertiveness practice, 5 practice sessions utilizing ABCDE principles were added to Park's program. To examine the effects of the program, differences between the two groups in assertive behaviors, interpersonal relations, communication conflicts, conflict management style and personnel turnover rate were analyzed using ANCOVA. The assertiveness training was effective in improving the nurses' assertiveness behaviors, but was not effective in improving interpersonal relations, reducing the subjects' communication conflicts, changing the conflict management style or reducing their personnel turnover rate. There have been many studies about factors affecting nurses' personnel turnover rates, but few have been done about methods of intervention to reduce the personnel turnover rate. Thus, this study provides a significant contribution in attempting such an intervention from nursing management perspectives.

    Learning models and academic ability may affect students’ achievement in science. This study, thus aimed to investigate the effect of numbered heads together (NHT) cooperative learning model on elementary students’ cognitive achievement in natural science. This study employed a quasi-experimental design with pretest-posttest non-equivalent control group with 2 x 2 factorial. There were two learning models compared NHT and the conventional, and two academic ability high and low. The results of ana Cova test confirmed the difference in the students’ cognitive achievement based on learning models and general academic ability. However, the interaction between learning models and academic ability did not affect the students’ cognitive achievement. In conclusion, teachers are strongly recommended to be more creative in designing learning using other types of cooperative learning models. Also, schools are required to create a better learning environment which is more cooperative to avoid unfair competition among students in the classroom and as a result improve the students’ academic ability. Further research needs to be conducted to explore the contribution of other aspects in cooperative learning toward cognitive achievement of students with different academic ability.

    The purpose of this quasi-experimental, nonequivalent pretest-posttest control group design study was to determine if any differences existed in upper elementary school students' science academic achievement when instructed using an 8-week integrated science and English language arts literacy supplemental instructional intervention in conjunction with traditional science classroom instruction as compared to when instructed using solely traditional science classroom instruction. The targeted sample population consisted of fourth-grade students enrolled in a public elementary school located in the southeastern region of the United States. The convenience sample size consisted of 115 fourth-grade students enrolled in science classes. The pretest and posttest academic achievement data collected consisted of the science segment from the Spring 2015, and Spring 2016 state standardized assessments. Pretest and posttest academic achievement data were analyzed using an ANCOVA statistical procedure to test for differences, and the researcher reported the results of the statistical analysis. The results of the study show no significant difference in science academic achievement between treatment and control groups. An interpretation of the results and recommendations for future research were provided by the researcher upon completion of the statistical analysis.

    The purpose of this study was to provide the first systematic evaluation in the United States of a community-based oral cancer awareness campaign. We used a non-equivalent control group design and random-digit-dialing methods to examine billboard effectiveness and pre- and post-billboard impact between intervention and control counties in adult probability samples in Florida, USA. Respondents in the intervention county were more likely than controls to correctly identify the billboard message to get tested for oral cancer, and less likely than controls to report ever having an oral cancer examination, or to have heard of oral cancer. Results of pre-post analyses within each county showed that oral cancer examinations were significantly more frequent in both counties after the campaign. There were no significant differences between counties on the proportion of individuals who reported having seen the campaign or on any other item measuring billboard awareness or impact. Results suggest the Florida billboard campaign had limited success in increasing public awareness. Future cancer awareness campaigns should incorporate theoretical models, target high-risk groups and the broader community and provide culturally relevant messages as part of a multi-media campaign.

    Background During the last few decades, marital tensions and stresses have influenced various dimensions of life. The objective of the current study was to examine the effects of combined psycho-physiological therapy (stretching therapy combined with breathing exercise) on sexual satisfaction among heterosexual men. Methods For this research, we used “convenience sampling” to select 80 males, who were then split equally into two groups, the intervention group and the control group, both groups containing men who had voiced a desire to be in the experimental group. For collection of data, we used an identical quasi-experimental design called the “nonequivalent control group.” Therapy sessions, each lasting 90 to 120 min, were carried out on the same 3 days of the week (Sunday, Tuesday, and Thursday) for a total of 20 sessions. The volunteers were selected from heterosexual men with stable relationships, who had been married a minimum of 6 months and were ages 20 to 55 years of age. Pre-tests, post-tests, and follow-up tests were conducted in a clinic at the Hospital Universiti Sains Malaysia (HUSM [1] ). For assessment, we used the sexual satisfaction subscale of the ENRICH [2] questionnaire. Results The intervention group had better post-test scores than the control group. Also, follow-up test scores for the intervention group were marginally better than those for the control group, but the difference did not reach statistical significance. Conclusions Combined psycho-physiological therapy including stretching and breathing exercise leads to improved sexual satisfaction. PMID:23522405

    This paper reports on the development and evaluation of an integrated clinical learning model to inform ongoing education for surgical nurses. The research aim was to evaluate the effectiveness of implementing a Respiratory Skills Update (ReSKU) education program, in the context of organisational utility, on improving surgical nurses' practice in the area of respiratory assessment. Continuous development and integration of technological innovations and research in the healthcare environment mandate the need for continuing education for nurses. Despite an increased worldwide emphasis on this, there is scant empirical evidence of program effectiveness. A quasi experimental pre test, post test non-equivalent control group design evaluated the impact of the ReSKU program on surgical nurses' clinical practice. The 2008 study was conducted in a 400 bed regional referral public hospital and was consistent with contemporary educational approaches using multi-modal, interactive teaching strategies. The study demonstrated statistically significant differences between groups regarding reported use of respiratory skills, three months after ReSKU program attendance. Between group data analysis indicated that the intervention group's reported beliefs and attitudes pertaining to subscale descriptors showed statistically significant differences in three of the six subscales. The construct of critical thinking in the clinical context, combined with clinical reasoning and purposeful reflection, was a powerful educational strategy to enhance competency and capability in clinicians.

    This study was undertaken to confirm the effects of autogenic training (AT) on stress response and heart rate variability in nursing school students experiencing stress related to clinical training. The study was carried out from September 2012 to April 2013 in a quasi-experimental nonequivalent control group using a pretest-posttest design. The participants were 40 nursing students in their third year at either of two nursing colleges. All consented to participate. Nineteen nursing students at one college were assigned to the experimental group and underwent the 8-week AT program, and the other 21 were assigned to the control group and did not undergo any training. Stress response was assessed by questionnaire and HRV was measured three times, that is, before the program, at the end of the program, and 6 months after the end of the AT program. A significant time/group interaction was found for stress response (F = 4.68, p = .012), a subjective indicator. However, no significant interaction was found for the objective indicators of heart rate variability, normalized low frequency (F = 2.59, p = .090), normalized high frequency (F = 2.59, p = .090), or low frequency to high frequency ratio (F = 1.38, p = .257). The results suggest that AT provides an acceptable approach to stress reduction in nursing students. Copyright © 2014. Published by Elsevier B.V.

    This study examined the effectiveness of a stress coping program based on mindfulness meditation on the stress, anxiety, and depression experienced by nursing students in Korea. A nonequivalent, control group, pre-posttest design was used. A convenience sample of 41 nursing students were randomly assigned to experimental (n=21) and control groups (n=20). Stress was measured with the PWI-SF (5-point) developed by Chang. Anxiety was measured with Spieberger's state anxiety inventory. Depression was measured with the Beck depression inventory. The experimental group attended 90-min sessions for eight weeks. No intervention was administered to the control group. Nine participants were excluded from the analysis because they did not complete the study due to personal circumstances, resulting in 16 participants in each group for the final analysis. Results for the two groups showed (1) a significant difference in stress scores (F=6.145, p=0.020), (2) a significant difference in anxiety scores (F=6.985, p=0.013), and (3) no significant difference in depression scores (t=1.986, p=0.056). A stress coping program based on mindfulness meditation was an effective intervention for nursing students to decrease their stress and anxiety, and could be used to manage stress in student nurses. In the future, long-term studies should be pursued to standardize and detail the program, with particular emphasis on studies to confirm the effects of the program in patients with diseases, such as cancer.

    Objectives. To evaluate the effects of Ving Tsun (VT) martial art training on the upper extremity muscle strength and eye-hand coordination of middle-aged and older adults. Methods. This study used a nonequivalent pretest-posttest control group design. Forty-two community-dwelling healthy adults participated in the study; 24 (mean age ± SD = 68.5 ± 6.7 years) underwent VT training for 4 weeks (a supervised VT session twice a week, plus daily home practice), and 18 (mean age ± SD = 72.0 ± 6.7 years) received no VT training and acted as controls. Shoulder and elbow isometric muscle strength and eye-hand coordination were evaluated using the Lafayette Manual Muscle Test System and a computerized finger-pointing test, respectively. Results. Elbow extensor peak force increased by 13.9% (P = 0.007) in the VT group and the time to reach peak force decreased (9.9%) differentially in the VT group compared to the control group (P = 0.033). For the eye-hand coordination assessment outcomes, reaction time increased by 2.9% in the VT group and decreased by 5.3% in the control group (P = 0.002). Conclusions. Four weeks of VT training could improve elbow extensor isometric peak force and the time to reach peak force but not eye-hand coordination in community-dwelling middle-aged and older adults.

    This study aimed to examine the effects of cognitive behavior therapy for insomnia (CBT-I) based on the mobile social networking service (SNS) on dysfunctional beliefs and attitudes about sleep, sleep quality, daytime sleepiness, depression, and quality of life among rotating-shift nurses in a hospital in Korea. A nonequivalent control group pre-post test design was used. The participants included 55 nurses with rotating three-shift work (25 in the experimental group and 30 in the control group). For the experimental group, CBT-I using mobile SNS was provided once a week for 60 minutes over six weeks. Data were analyzed using descriptive statistics, χ²-test, independent samples t-test, and Mann-whitney U test with the SPSS 21.0 program. In the homogeneity test of the general characteristics and study variables, there were no significant differences between the two groups. Nurses in the experimental group had significantly lower scores on dysfunctional beliefs and attitudes regarding sleep and sleepiness than nurses in the control group. Nurses in the experimental group had significantly higher scores on sleep quality and quality of life than nurses in the control group. These findings indicate that using the mobile SNS-based CBT-I is feasible and has significant and positive treatment-related effects on rotating-shift nurses' irrational thoughts and beliefs in association with sleep, sleep quality, daytime sleepiness, and quality of life. These contribute to expanding our knowledge of rotating-shift nurses' sleep issues and their preferences for intervention. © 2017 Korean Society of Nursing Science

    A number of mammalian genes exhibit the unusual properties of random monoallelic expression and random asynchronous replication. Such exceptional genes include genes subject to X inactivation and autosomal genes including odorant receptors, immunoglobulins, interleukins, pheromone receptors, and p120 catenin. In differentiated cells, random asynchronous replication of interspersed autosomal genes is coordinated at the whole chromosome level, indicative of chromosome-pair non-equivalence. Here we have investigated the replication pattern of the random asynchronously replicating genes in undifferentiated human embryonic stem cells, using fluorescence in situ hybridization based assay. We show that allele-specific replication of X-linked genes and random monoallelic autosomal genes occur in human embryonic stem cells. The direction of replication is coordinated at the whole chromosome level and can cross the centromere, indicating the existence of autosome-pair non-equivalence in human embryonic stem cells. These results suggest that epigenetic mechanism(s) that randomly distinguish between two parental alleles are emerging in the cells of the inner cell mass, the source of human embryonic stem cells.

    It is generally believed that, in the thermodynamic limit, the microcanonical description as a function of energy coincides with the canonical description as a function of temperature. However, various examples of systems for which the microcanonical and canonical ensembles are not equivalent have been identified. A complete theory of this intriguing phenomenon is still missing. Here we show that ensemble nonequivalence can manifest itself also in random graphs with topological constraints. We find that, while graphs with a given number of links are ensemble equivalent, graphs with a given degree sequence are not. This result holds irrespective of whether the energy is nonadditive (as in unipartite graphs) or additive (as in bipartite graphs). In contrast with previous expectations, our results show that (1) physically, nonequivalence can be induced by an extensive number of local constraints, and not necessarily by long-range interactions or nonadditivity, (2) mathematically, nonequivalence is determined by a different large-deviation behavior of microcanonical and canonical probabilities for a single microstate, and not necessarily for almost all microstates. The latter criterion, which is entirely local, is not restricted to networks and holds in general.

    Objectives To describe (1) the content of a transition programme for young people with juvenile idiopathic arthritis (JIA) designed as a brief intervention, (2) the rationale and design of a mixed-methods study evaluating the clinical impact of this transition programme and (3) to provide baseline data of the intervention group. Design An ‘embedded experimental’ design is used for the evaluation of the transition programme. A ‘one-group pretest-posttest, with a non-equivalent posttest-only comparison group design’ is used to quantitatively evaluate the impact of the transition programme, applying both longitudinal and comparative analyses. Subsequently, experiences of adolescents and their parents who participated in the experimental group will be analysed qualitatively using content analysis. Setting Participants in the intervention are recruited at a tertiary care centre in Belgium. The comparison group participants are recruited from one tertiary and three secondary care centres in Belgium. Participants The intervention group consists of 33 young people (25 females; 8 males) with a median age of 16 years. Main diagnoses are persistent or extended oligoarticular JIA (33%), polyarticular JIA (30%), enthesitis-related JIA (21%) or systemic arthritis (15%). Intervention The transition programme comprises eight key components: (1) transition coordinator; (2) providing information and education; (3) availability by telephone; (4) information about and contact with an adult care programme; (5) guidance of parents; (6) meeting with peers; (7) transfer plan; and (8) actual transfer to adult care. Primary and secondary outcomes The primary outcome is health status, as perceived by the adolescents. Secondary outcomes are health status, as perceived by the parents; medication adherence; illness-related knowledge; quality of life; fatigue; promotion of independence; support of autonomy; behavioural control and psychological control. Results At baseline, the median score was 69.2 (Q1=60.0;Q3=92.9) on psychosocial health and 68.8 (Q1=56.3; Q3=89.1) on physical health. Rheumatic-specific health scores ranged from 62.5 to 100. Conclusions We present the rationale and design of a study intended to evaluate a transition programme for adolescents with JIA as a brief intervention. PMID:24302502

    We introduced a series of computer-supported workshops in our undergraduate statistics courses, in the hope that it would help students to gain a deeper understanding of statistical concepts. This raised questions about the appropriate design of the Virtual Learning Environment (VLE) in which such an approach had to be implemented. Therefore, we investigated two competing software design models for VLEs. In the first system, all learning features were a function of the classical VLE. The second system was designed from the perspective that learning features should be a function of the course's core content (statistical analyses), which required us to develop a specific-purpose Statistical Learning Environment (SLE) based on Reproducible Computing and newly developed Peer Review (PR) technology. The main research question is whether the second VLE design improved learning efficiency as compared to the standard type of VLE design that is commonly used in education. As a secondary objective we provide empirical evidence about the usefulness of PR as a constructivist learning activity which supports non-rote learning. Finally, this paper illustrates that it is possible to introduce a constructivist learning approach in large student populations, based on adequately designed educational technology, without subsuming educational content to technological convenience. Both VLE systems were tested within a two-year quasi-experiment based on a Reliable Nonequivalent Group Design. This approach allowed us to draw valid conclusions about the treatment effect of the changed VLE design, even though the systems were implemented in successive years. The methodological aspects about the experiment's internal validity are explained extensively. The effect of the design change is shown to have substantially increased the efficiency of constructivist, computer-assisted learning activities for all cohorts of the student population under investigation. The findings demonstrate that a content-based design outperforms the traditional VLE-based design.

    The effect of biaxial strain on the magnetism of α″-Fe16N2 was investigated by the first principles calculations. The GGA, GGA + U and HSE06 calculations give the same result that the magnetic moments increase with the biaxial strain in the ab plane. All non-equivalent Fe atoms contribute to the increase of magnetic moments, although the variations of inter-atomic distances between non-equivalent Fe and N are different. Additionally, the magnetic anisotropy of Fe16N2 could be controlled by the biaxial strain.

    The purpose of this study was to evaluate the effects of an educational video program on bowel preparation for a colonoscopy. The study used a non-equivalent control group and non-synchronized design as a quasi-experimental research involving 101 participants undergoing bowel preparation for a colonoscopy (experimental group 51, control group 50 subjects) at W. university hospital, from Aug. 7 to Oct. 31, 2013. The control group received verbal education with an explanatory note while the experimental group received education using a video program. To measure knowledge of diet restrictions and compliance with ingesting bowel preparation solutions, a questionnaire, based on The Korean Society of Gastrointestinal Endoscopy's Guide (2003), developed by Sam-Sook You, was used after revisions and supplementation was done. To measure bowel cleanness, the 'Aronchick Bowel Preparation Scale' was adopted. Data were analyzed using the SPSS WIN 12.0 program. A higher proportion of the experimental group showed a positive change in knowledge level on diet restrictions (U=1011.50, p=.035) and ingestion of bowel preparation solutions (U=980.50, p=.019), a higher level of compliance with diet restrictions (U=638.50, p<.001), ingesting bowel preparation solutions (U=668.00, p<.001) and the level of bowel cleanness (χ²=17.00, p<.001) than the control group. The results of this study indicate that a video educational program for patients having a colonoscopy can improve knowledge, level of compliance with diet restrictions, ingestion of bowel preparation solutions, and bowel cleanness. Therefore video educational program should be used with this patient group.

    Improper practices and unprofessional conduct in clinical research have been shown to waste a significant portion of healthcare funds and harm public health. Our objective was to evaluate the effectiveness of educational or policy interventions in research integrity or responsible conduct of research on the behaviour and attitudes of researchers in health and other research areas. We searched the CENTRAL, MEDLINE, LILACS and CINAHL health research bibliographical databases, as well as the Academic Search Complete, AGRICOLA, GeoRef, PsycINFO, ERIC, SCOPUS and Web of Science databases. We performed the last search on 15 April 2015 and the search was limited to articles published between 1990 and 2014, inclusive. We also searched conference proceedings and abstracts from research integrity conferences and specialized websites. We handsearched 14 journals that regularly publish research integrity research. We included studies that measured the effects of one or more interventions, i.e. any direct or indirect procedure that may have an impact on research integrity and responsible conduct of research in its broadest sense, where participants were any stakeholders in research and publication processes, from students to policy makers. We included randomized and non-randomized controlled trials, such as controlled before-and-after studies, with comparisons of outcomes in the intervention versus non-intervention group or before versus after the intervention. Studies without a control group were not included in the review. We used the standard methodological procedures expected by Cochrane. To assess the risk of bias in non-randomized studies, we used a modified Cochrane tool, in which we used four out of six original domains (blinding, incomplete outcome data, selective outcome reporting, other sources of bias) and two additional domains (comparability of groups and confounding factors). We categorized our primary outcome into the following levels: 1) organizational change attributable to intervention, 2) behavioural change, 3) acquisition of knowledge/skills and 4) modification of attitudes/perceptions. The secondary outcome was participants' reaction to the intervention. Thirty-one studies involving 9571 participants, described in 33 articles, met the inclusion criteria. All were published in English. Fifteen studies were randomized controlled trials, nine were controlled before-and-after studies, four were non-equivalent controlled studies with a historical control, one was a non-equivalent controlled study with a post-test only and two were non-equivalent controlled studies with pre- and post-test findings for the intervention group and post-test for the control group. Twenty-one studies assessed the effects of interventions related to plagiarism and 10 studies assessed interventions in research integrity/ethics. Participants included undergraduates, postgraduates and academics from a range of research disciplines and countries, and the studies assessed different types of outcomes.We judged most of the included randomized controlled trials to have a high risk of bias in at least one of the assessed domains, and in the case of non-randomized trials there were no attempts to alleviate the potential biases inherent in the non-randomized designs.We identified a range of interventions aimed at reducing research misconduct. Most interventions involved some kind of training, but methods and content varied greatly and included face-to-face and online lectures, interactive online modules, discussion groups, homework and practical exercises. Most studies did not use standardized or validated outcome measures and it was impossible to synthesize findings from studies with such diverse interventions, outcomes and participants. Overall, there is very low quality evidence that various methods of training in research integrity had some effects on participants' attitudes to ethical issues but minimal (or short-lived) effects on their knowledge. Training about plagiarism and paraphrasing had varying effects on participants' attitudes towards plagiarism and their confidence in avoiding it, but training that included practical exercises appeared to be more effective. Training on plagiarism had inconsistent effects on participants' knowledge about and ability to recognize plagiarism. Active training, particularly if it involved practical exercises or use of text-matching software, generally decreased the occurrence of plagiarism although results were not consistent. The design of a journal's author contribution form affected the truthfulness of information supplied about individuals' contributions and the proportion of listed contributors who met authorship criteria. We identified no studies testing interventions for outcomes at the organizational level. The numbers of events and the magnitude of intervention effects were generally small, so the evidence is likely to be imprecise. No adverse effects were reported. The evidence base relating to interventions to improve research integrity is incomplete and the studies that have been done are heterogeneous, inappropriate for meta-analyses and their applicability to other settings and population is uncertain. Many studies had a high risk of bias because of the choice of study design and interventions were often inadequately reported. Even when randomized designs were used, findings were difficult to generalize. Due to the very low quality of evidence, the effects of training in responsible conduct of research on reducing research misconduct are uncertain. Low quality evidence indicates that training about plagiarism, especially if it involves practical exercises and use of text-matching software, may reduce the occurrence of plagiarism.

    This experimental study examined the effects of participation in a Supplemental Instruction (SI) program on student performance in a college level biology course. SI is an academic support program which incorporates study techniques into the framework of an academic course through discussion sessions. According to Blanc, DeBuhr, and Martin (1983) and Kenney (1988), students who experienced Supplemental Instruction had higher course grades, semester grade point averages, and rates of re-enrollment than did non-participants. The present study was conducted within the scheduled discussion sections of a large lecture class of biology for science majors (n = 135). The researcher and another graduate student conducted these discussion sessions in which half of the sections served as the SI treatment group and half of the sections served as the non-SI (traditional) control group. This design eliminated both time on task and motivation as potential contaminating variables. This posttest only, quasi-experimental design study uses a modified nonequivalent control group design. The academic performance of students who participated in SI discussion sessions was compared to the academic performance of students who participated in traditional review-type discussion sessions. Other research questions examined the interactive effect of SI on student performance with respect to SI leader experience, student ability level as measured by total SAT scores, previous academic success as measured by previous college GPA, and different cognitive level of examination questions. t-test and ANOVA statistical methods were used to analyze the data. The results of the t-tests to compare the means of the SI group to the non-SI group (p < .458) do not indicate any significant difference in the semester course scores between the two groups. Thus, the data did not show an overall effect of SI on student performance. The most important results obtained from this study are those with respect to the interactive effect of SI and student ability groups as measured by SAT total scores and prior college GPA. In this study the students in middle ability groups seemed to benefit more from SI than did the lower and higher ability students.

    Background: Case-based learning (CBL) is simply teaching the concept to the students based on the cases. CBL involves a case, which is a scenario based on daily life, and study questions related to the case, which allows students to discuss their ideas. Chemical kinetics is one of the most difficult concepts for students in chemistry. Students have generally low levels of conceptual understanding and many alternative conceptions regarding it. Purpose: This study aimed to explore the effect of CBL on dealing with students' alternative conceptions about chemical kinetics. Sample: The sample consists of 53 high school students from one public high school in Turkey. Design and methods : Nonequivalent pre-test and post-test control group design was used. Reaction Rate Concept Test and semi-structured interviews were used for data collection. Convenience sampling technique was followed. For data analysis, the independent samples t-test and ANOVA was performed. Results : Both concept test and interview results showed that students instructed with cases had better understanding of core concepts of chemical kinetics and had less alternative conceptions related to the subject matter compared to the control group students, despite the fact that it was impossible to challenge all the alternative conceptions in the experimental group. Conclusions: CBL is an effective teaching method for challenging students' alternative conceptions in the context of chemical kinetics. Since using cases in small groups and whole class discussions has been found to be an effective way to cope with the alternative conceptions, it can be applied to other subjects and grade levels in high schools with a higher sample size. Furthermore, the effect of this method on academic achievement, motivation and critical thinking skills are other variables that can be investigated for future studies in the subject area of chemistry.

    Adolescents with congenital heart disease need to increase their resilience in the face of challenges in order to preserve their health and quality of life. This study aimed to develop a resilience improvement program for adolescents with congenital heart disease and also to evaluate any change in resilience and quality of life as a measure of the effectiveness of the resilience improvement programs. A nonequivalent control group pretest-posttest study was designed. Twenty-five adolescents who attended the first resilience improvement program were included in the experimental group, and 31 adolescents who took part in the second program were placed in the control group. Adolescents with congenital heart disease completed a self-report questionnaire on three separate occasions: the pretest, the first posttest and the second posttest. The self-report questionnaire included general characteristics and instruments to measure resilience and quality of life. For the longitudinal analysis, generalized estimating equations were used to evaluate the difference in the estimated average trajectories of resilience and quality of life changes. Independent predictors of resilience improvement in adolescents with congenital heart disease were the experimental group ( p=0.02) and middle and high school students ( p=0.02). Quality of life was not associated with membership in the experimental group. However, males scored higher than females on quality of life measures ( p=0.02). It is essential for healthcare providers to apply various programs, including those targeted at accepting illness, improving autonomy and independently managing disease, to adolescents with congenital heart disease.

    The purpose of this study was to examine effects of a dietary program based on self-efficacy theory on dietary adherence, physical status and quality of life (QoL) in hemodialysis patients. A non-equivalent control group pre-post test design was used. The intervention group received the dietary program for 8 weeks from August 4 to September 26, 2014. The control group received only usual care. ANCOVA showed that dietary adherence (F=64.75, p<.001) was significantly different between the two groups. Serum albumin (F=12.13, p =.001), interdialytic weight gain (F=56.97, p<.001), calories (F=15.80, p<.001) as physical status indices were significantly different, but serum potassium (F=2.69, p=.106) and serum phosphorus (F=1.08, p=.303) showed no significant difference between the two groups. In terms of health-related QoL, the physical component scale (F=10.05, p=.002) and the mental component scale (F=16.66, p<.001) were significantly different between the two groups. In addition, in terms of diet related QoL, diet level (F=35.33, p<.001) and satisfaction level (F=15.57, p<.001) were significantly different between the two groups, but dietary impact level (F=1.23, p =.271) was not significantly different. Findings show that the dietary program based on self-efficacy theory is an effective nursing intervention program to improve adherence to diet, and to maintain physical status and QoL for hemodialysis patients.

    The goal of the present study was to determine whether an active learning/teaching strategy facilitated with mobile technologies can improve students' levels of memory retention of key physiological concepts. We used a quasiexperimental pretest/posttest nonequivalent group design to compare the test performances of second-year medical students (n = 311) taught by conventional didactic methods (traditional group) with those involved in a case-based problem-solving learning approach facilitated with mobile phones as web-based "clickers" (experimental group). Using their cell phones, students answered the same questions about the key physiological concepts three times. A pretest to determine their baseline knowledge was followed by two followup tests after 1 wk and 2 mo, respectively. The experimental group scored a mean of 93.2% correct items after 1 wk and 84.8% correct items after 2 mo [95% confidence intervals: (89.4, 97.0) and (79.4, 90.3), respectively]. Compared with their colleagues in the traditional group who scored 33.3% [95% confidence interval: (18.9, 47.8)] and 38.5% [95% confidence interval: (23.6, 53.4)] correct items, respectively, this was a significant increase of ∼50% (P < 0.0001). Furthermore, for the experimental group, Cohen's effect size (d) values of d = 1.67 (1-wk posttest) and d = 1.38 (2-mo posttest) suggested a very high practical significance. In contrast, in the traditional group, Cohen's d values of d = 0.04 (1-wk posttest) and d = 0.15 (2-mo posttest) assumed a very low practical significance.

    The purpose of this study was to examine the effects of unstructured play activities on the anxiety levels of hospitalized children. A nonequivalent control group pretest posttest design was employed for this study. The sample included children (N = 165) ages 4-7 years admitted to a large pediatric referral center in the United Arab Emirates. The control group (n = 84) received usual care, while the experimental group (n = 81) engaged in age-appropriate unstructured play activities using disposable games and toys. Parents and siblings, if present, were encouraged to participate. Research assistants conducted the play activities twice a day, with 30-min morning and evening sessions. Anxiety was measured at baseline and at the end of days 2 and 3 with a translated form of the Short-State-Trait Anxiety Inventory for Children. Anxiety scores in both groups were similar at baseline and decreased significantly over the 3 days. Compared with the control group, anxiety scores in the intervention group were significantly lower on day 2 (12.7 ± 2.3 vs. 10.7 ± 2.5, p = .003) and day 3 (10.6 ± 2.2 vs. 9.47 ± 2.4, p < .001). The greatest decrease occurred in the percentage of children in the experimental group with medium-level anxiety scores: baseline (n = 61, 75%), day 2 (n = 24, 30%), and day 3 (n = 0, 0%). This simple, low-cost play intervention implemented by nurses resulted in statistically and clinically significant decreases in the anxiety levels of children in an acute inpatient setting. © 2016, Wiley Periodicals, Inc.

    Research has shown that the use of power mobility devices is safe and beneficial for motor and cognitive development in children with motor disabilities; nevertheless, strong evidence of the benefits for social skill development is limited. This study aimed to examine the effects of combining ride-on car training with an adult-directed, social interaction program in a hospital-based environment on mobility and social functions in young children with motor disabilities. This study used a prospective, nonequivalent pretest-posttest control group design. Twenty-nine young children with motor disabilities, aged between 1 and 3 years, were recruited from local hospitals in Taiwan. The treatment group ( n  = 15) underwent 2-h ride-on car training sessions twice per week for a total of 9 weeks in the hospital environment. The control group ( n  = 14) underwent a 9-week home education program (mean: 200 min/week) focusing on mobility and social skills training. The Chinese version of the Pediatric Evaluation of Disability Inventory, Parenting Stress Index, and Goal Attainment Scaling were administered to all participants before and after the intervention, and at the end of the 9-week follow-up phase. Mobility and social functions significantly improved in both groups after the 9-week intervention, but this improvement was not maintained at the follow-up phase. The treatment group showed significantly better improvement in social function, parenting stress levels, and goal achievement than the control group at posttest. This two-group design study showed the benefits of combining a ride-on car use with a family-centered, structured, social interaction program for positive impacts on mobility, social function, and parenting stress levels. The combination of a modified ride-on car and a social training program has the potential to enhance socialization in young children with motor disabilities. www.ClinicalTrials.gov, identifier NCT02527499.

    The use of information and communication technology (ICT) in learning process resulted in positive impact to students’ output. This research investigated the difference of improvement of students’ creativity and cognitive achievement due to the use of android-based games on Chemistry Nomenclature in learning method of team-assisted individualization (TAI) into the improvement of students’ creativity and cognitive achievement. This was an quasi experiment research with non-equivalent pretest-posttest control group design involving 2 groups of students of X grade of a senior high school in Yogyakarta, Indonesia, SMAN 1 Seyegan, Sleman. The groups were experiment and control which were chosen randomly, involving 32 students in each group. The difference of learning model in the two groups were the use of android-based games within learning model of TAI in the experiment group, but it was only the use of TAI model in control group. The android-based games were developed and validated previously in this investigation, and were excellent in quality for the use in Chemistry learning process, and were reported separately. The data of both students’ creativity and cognitive achievement were measured before and after learning process. Data of students’ creativity were collected with the instruments of questionnaire and observation sheets, and the data of cognitive achievement were collected with a set of test. Statistical analysis of MANOVA was used to analyze data to measure the difference of the improvement of students’ creativity and cognitive achievement between experiment and control groups. The results showed that the improvement of creativity and cognitive achievement of students in the experiment group was higher significantly than that in control group.

    This study investigated the effect of the flipped classroom on urban high school students' motivation and academic achievement in a high school science course. In this quantitative study, the sample population was comprised of North Star High School 12th grade students enrolled in human anatomy and physiology. A quasi-experimental, pretest-posttest non-equivalent group design was conducted. After receipt of Liberty University Institutional Review Board approval and the school district's Department of Research and Evaluation for School Improvement, students completed a pretest comprised of the Science Motivation Questionnaire II (SMQ-II) and the Human Anatomy and Physiology Unit Test. Participants in the experimental group engaged in the treatment, the flipped classroom, using instructional materials on the educational website, Edmodo(TM), and applied content material taught using hands-on activities inclusive of assigned laboratory experiments. Participants in the control group received instruction using traditional face-to-face lecture-homework format while also engaging in assigned laboratory experiments. After the completion of the treatment all participants completed a posttest. Data from both the pretest and posttest was statistically analyzed individually using two separate one-way ANOVA/ANCOVA analyses; and researcher reported the results of the statistical analyses. After completion of the analyses, and interpretation of the results, recommendations for future research were given.

    To evaluate the effect of a publicly sponsored drug-free workplace program on reducing the risk of occupational injuries. Workers' compensation claims data from the Washington State Department of Labor and Industries covering the period 1994 through 2000 and work-hours data reported by employers served as the data sources for the analysis. We used a pre-post design with a nonequivalent comparison group to assess the impact of the intervention on injury risk, measured in terms of differences in injury incidence rates. Two hundred and sixty-one companies that enrolled in the drug-free workplace program during the latter half of 1996 were compared with approximately 20,500 nonintervention companies. We tested autoregressive, integrated moving-average (ARIMA) models to assess the robustness of our findings. The drug-free workplace intervention was associated (p < .05) with a statistically significant decrease in injury rates for three industry groups: construction, manufacturing, and services. It was associated (p < .05) with a reduction in the incidence rate of more serious injuries involving four or more days of lost work time for two industry groups: construction and services. The ARIMA analysis supported The drug-free workplace program we studied was associated with a selective, industry-specific preventive effect. The strongest evidence of an intervention effect was for the construction industry. Estimated net cost savings for this industry were positive though small in magnitude.

    Metal nanoparticles are heterogeneous catalysts and have a multitude of non-equivalent, catalytic sites on the nanoparticle surface. The product dissociation step in such reaction schemes can follow multiple pathways. Proposed here for the first time is a completely analytical theoretical framework, based on the first passage time distribution, that incorporates the effect of heterogeneity in nanoparticle catalysis explicitly by considering multiple, non-equivalent catalytic sites on the nanoparticle surface. Our results show that in nanoparticle catalysis, the effect of dynamic disorder is manifested even at limiting substrate concentrations in contrast to an enzyme that has only one well-defined active site.

    The purposes of this research are: (1) to identify learning quality in Model Eliciting Activities (MEAs) using a Metaphorical Thinking (MT) approach regarding qualitative and quantitative; (2) to analyze mathematical literacy of students based on Self-Efficacy (SE). This research is mixed method concurrent embedded design with qualitative research as the primary method. The quantitative research used quasi-experimental with non-equivalent control group design. The population is VIII grade students of SMP Negeri 3 Semarang Indonesia. Quantitative data is examined by conducting completeness mean test, standard completeness test, mean differentiation test and proportional differentiation test. Qualitative data is analyzed descriptively. The result of this research shows that MEAs learning using MT approach accomplishes good criteria both quantitatively and qualitatively. Students with low self-efficacy can identify problems, but they are lack ability to arrange problem-solving strategy on mathematical literacy questions. Students with medium self-efficacy can identify information provided in issues, but they find difficulties to use math symbols in making a representation. Students with high self-efficacy are excellent to represent problems into mathematical models as well as figures by using appropriate symbols and tools, so they can arrange strategy easily to solve mathematical literacy questions.

    The purpose of this study was to determine the effects of employing an STS instructional model that addresses each of the four goal levels of STS education versus an instructional model containing only life science content, on seventh grade students' participation in citizenship action on STS issues. A modified version of the non-equivalent control group quasi-experimental research design was used with seventeen intact seventh grade life science classes, ten of which received STS instruction ( N = 264) and seven of which received life science instruction ( N = 136) over 20 school days. The STS instruction sequentially addressed each of the four goal levels for STS education. Data were collected using the Actions Taken on Public Issues instrument to measure citizenship behaviors. ANOVA and repeated measures ANOVA were employed to analyze data. It was concluded from the findings that employment of an STS issue investigation with an action instructional model that addressed the four goal levels of STS education significantly increased seventh grade students' participation in citizenship actions on STS issues. Implications and recommendations are provided.

    This study aims to find out the improvement of cognitive ability of students on the implementation of cooperative learning model of peer-tutoring by using problem-solving approach. The research method used is mix method of Sequential Explanatory strategy and pretest post-test non-equivalent control group design. The participants involved in this study were 68 grade 10 students of Vocational High School in Bandung that consisted of 34 samples of experimental class and 34 samples of control class. The instruments used include written test and questionnaires. The improvement of cognitive ability of students was calculated using the N- gain formula. Differences of two average scores were calculated using t-test at significant level of α = 0.05. The result of study shows that the improvement of cognitive ability in experimental class was significantly different compared to the improvement in the control class at significant level of α = 0.05. The improvement of cognitive ability in experimental class is higher than in control class.

    This paper explores HIV/AIDS stigma in the socio-cultural context of Nakhon Ratchasima Province in the northeastern region of Thailand. Action research was used to develop a community participation intervention. The intervention was implemented in one village over a period of eight months. We describe the intervention and then test its effect on HIV/AIDS knowledge and HIV/AIDS stigma using a non-equivalent pre-test-post-test control group design. Analysis of co-variance confirms that, controlling for initial levels of HIV/AIDS knowledge and stigma, the intervention had a significant effect on HIV/AIDS knowledge score (p<0.01) and HIV/AIDS stigma score (p<0.01). Participatory observations by the researchers on villagers' perceptions and behaviour were consistent with the quantitative results. These results suggest that community interventions which empower the community, combined with a financial contribution to reduce resource constraints, are a useful and effective means of increasing interaction between people living with HIV/AIDS (PLWHA) and other community members, increasing tolerance and reducing HIV/AIDS stigma.

    Blended learning approaches, in which in-person and online course components are combined in a single course, are rapidly increasing in health sciences education. Evidence for the relative effectiveness of blended learning versus more traditional course approaches is mixed. The impact of a blended learning approach on student learning in a graduate-level public health course was examined using a quasi-experimental, non-equivalent control group design. Exam scores and course point total data from a baseline, "traditional" approach semester (n = 28) was compared to that from a semester utilizing a blended learning approach (n = 38). In addition, student evaluations of the blended learning approach were evaluated. There was a statistically significant increase in student performance under the blended learning approach (final course point total d = 0.57; a medium effect size), even after accounting for previous academic performance. Moreover, student evaluations of the blended approach were very positive and the majority of students (83%) preferred the blended learning approach. Blended learning approaches may be an effective means of optimizing student learning and improving student performance in health sciences courses.

    The purpose of this study was to examine the effects of aromatherapy on stress responses, autonomic nervous system (ANS) activity, and blood pressure in patients hospitalized to receive coronary angiography (CAG). A non-equivalent control group with a pretest-posttest design was used. The subjects were patients admitted to the day angiography room to receive CAG at E University Hospital (34 in the experimental group and 30 in the control group). The experimental group treatment was inhalation of the aroma oil blended with lavender, ylang-ylang, and neroli at a ratio of 4:2:1 twice before and after CAG. The measurements of stress index, ANS activity, and blood pressure were performed 5 times as follows: at admission, at pre-CAG after treatment I, at post-CAG, 2 hours after treatment II, and 4 hours after treatment II. The data were analyzed using the Mann-Whitney U Test and repeated-measures analysis of variance. Significant interactions in the high frequency of ANS (F=5.58, p=.005) were observed between group and time. Stress index (z=2.14, p=.016), systolic blood pressure (z=4.14, p<.005), and diastolic blood pressure (z=3.28, p=.001) were significantly different between the experimental and control groups after 4 hours of treatment II. The findings showed that aromatherapy was not effective before CAG, but was effective after CAG. Therefore, aromatherapy can be used as a nursing intervention for patients receiving CAG. © 2018 Korean Society of Nursing Science.

    Stroke is a prevalent condition found in elderly, rural populations. However, stroke education, which can be effective in addressing the risks, is often difficult to provide in these remote regions. The objective of this study is to evaluate the effectiveness of delivering stroke education to elderly individuals through telehealth versus in-person stroke prevention education methods. A quasi-experimental nonequivalent control group design was used in this study. A convenience sample of 11 elderly adults (36% men, 64% women) with a mean age of 70 was selected from an Appalachian Program for All Inclusive Care for the Elderly (day care) facility. Subjects completed preintervention surveys, received a 20-min group in-person or telehealth delivered education session, and then completed the postintervention surveys. Satisfaction with delivery method and post-education knowledge was equivalent between the two groups. Knowledge increased in both groups after the educational programs. Likelihood of reducing risk factors showed no differences pre-posttest. However, there were significant improvements in the pre-post likelihood scores of the telehealth group in contrast to the in-person group. This project provided a rural, high-risk population access to telehealth stroke education, thus enabling these individuals to receive education at a distance from experts in the field. The telehealth program was found to be equivalent to in-person stroke education in regards to satisfaction, knowledge, and likelihood of making changes to decrease vascular risk factors. The study demonstrated feasibility in providing effective stroke education through telehealth, thus suggesting an often overlooked route for providing patient education at a distance.

    This study was conducted to identify the effects of kangaroo care on the physiological functions of preterm infants, maternal-infant attachment, and maternal stress. For this study, a quasi-experiment design was used with a nonequivalent control group, and a pre- and post-test. Data were collected from preterm infants with corrected gestational ages of ≥33weeks who were hospitalized between May and October 2011. Twenty infants were assigned to the experimental group and 20 to the control group. As an intervention, kangaroo care was provided in 30-min sessions conducted thrice a week for a total of 10 times. The collected data were analyzed by using the t test, repeated-measures ANOVA, and the ANCOVA test. After kangaroo care, the respiration rate significantly differed between the two groups (F=5.701, p=.020). The experimental group had higher maternal-infant attachment scores (F=25.881, p<.001) and lower maternal stress scores (F=47.320, p<.001) than the control group after the test. In other words, kangaroo care showed significantly positive effects on stabilizing infant physiological functions such as respiration rate, increasing maternal-infant attachment, and reducing maternal stress. This study suggests that kangaroo care can be used to promote emotional bonding and support between mothers and their babies, and to stabilize the physiological functions of premature babies. Kangaroo care may be one of the most effective nursing interventions in the neonatal intensive care unit for the care of preterm infants and their mothers. Copyright © 2016 Elsevier Inc.

    The purpose of this study was to investigate the effects of a self-esteem improvement program on self-esteem and peer attachment in elementary school children with observed problematic behaviors. This study is a quasi-experimental study with a nonequivalent control group pretest-post-test design. A total of 47 fourth grade elementary school students participated in this study. The program was provided for 45 minutes once a week; a total of 12 sessions were completed with a group in the classroom for the experimental group. Child Problem-Behavior Screening Questionnaire was used to measure problematic behavior. Self-esteem was measured using the Rosenberg's Self-esteem Questionnaire, and peer attachment was measured using the Inventory of Parent and Attachment. Measuring was performed right after the program was done (post 1) and 1 month after the program was finished (post 2). To compare the differences in self-esteem and peer attachment between groups, repeated measures analysis of variance was used. Most participants in the experimental group were 10 years old (62.5%, range 10-11), male (52.0%) and with middle grade point average (64.0%). The self-esteem scores in the experimental group were significantly higher than those of the control group (F = 26.64, p < .001). The peer attachment scores in the experimental group were significantly higher than those of the control group (F = 6.48, p = .014). The self-esteem improvement program in this study improved the self-esteem and peer attachment in elementary school children. The self-esteem program helped acknowledge the peer's name and increased their connections. The program needs to be considered as a formal and consistent program. Copyright © 2015.

    Problem-based learning (PBL) has become a distinct approach in learning. To assess the effectiveness of PBL in teaching ethics to medical students and the effect it has on their ethical reasoning, we decided to hold a PBL ethics workshop and then evaluate them based on pretest and posttest. This quasi-experimental comparative study in Shiraz University of Medical Sciences was designed based on pretest-posttest nonequivalent groups. After obtaining their consent, 120 health care providers were randomly selected and assigned in 4 groups and then asked to attend the ethics workshop. For measuring the participants' ethical reasoning through pretesting and posttesting, a case study consisting of 21 multiple-choice questions (cognitive domain-apply level) was performed. Data were then collected using a questionnaire, which was completed by the participants and analyzed using SPSS software (version 17). The comparison between the participants' attitude and knowledge toward ethics before and after the workshop revealed that all indices in the cognitive domain were changed (P < .001). The scores of pretest and posttest were significantly different. As to the results of our study, the PBL groups showed a more positive learning attitude and higher motivation in comparison with the control group who were subjected to traditional-based method of learning. The result of our study suggests that PBL can and should be used as an alternative method in teaching ethics in medical students because it is more effective and motivates the students.

    Diagnosing undernutrition in hospitalized pediatric populations is crucial to provide timely nutrition interventions. Handgrip strength (HGS), a measurement of muscle function, is a reliable indicator of undernutrition. However, limited research exists on HGS in hospitalized pediatric patients. The primary aim of this study was to determine if HGS differed between hospitalized children within 48 hours of admission and nonhospitalized children. A secondary purpose was to describe the association of HGS with height, weight, body mass index (BMI), mid upper arm circumference (MUAC), activity level, disease severity, nutrition risk, and nutrition intervention. One hundred nine hospitalized and 110 nonhospitalized patients aged 6-14 years participated in this cross-sectional nonequivalent control group design study. Weight, height, MUAC, and HGS were measured within 48 hours of hospital admission for the hospitalized group or immediately following a well-child visit for the control group. Based on analysis of covariance, the HGS was estimated to be 12.4 ± 0.37 kgF (mean ± SE) for hospitalized subjects and 13.1 ± 0.37 for nonhospitalized subjects ( P = .2053). HGS was associated with age ( P < .0001), height ( P < .0001), dominant hand ( P < .0001), and MUAC z scores ( P = .0462). HGS was not significantly different between hospitalized and nonhospitalized participants, although anthropometric measurements were similar between groups. A strong relationship was demonstrated between HGS and BMI and MUAC z scores. Further research is needed that examines serial HGS measurements, feasibility in hospitalized patients, and the association of HGS measurements and nutrition risk.

    An ergonomics intervention program (EIP) was conducted with male employees working in the pressing and storage sections of a metal autoparts factory in Samut Prakan Province, Thailand. The objectives of this study were to assess the causes of injuries in the pressing and storage sections of that factory, and to improve working conditions by reducing worker injuries from accidents and low back muscular discomfort, using an EIR The study design used a participatory research approach which was quasi-experimental with pretest-posttest evaluations, with a non-equivalent control group. A total of 172 male participants working in Building A were the target group for assessing causes of injury. A retrospective study of official accident information, and questionnaires for general information, health and muscular discomfort, injury frequency rate (IFR), injury severity rate (ISR), medical expenses, and EIP design. Two groups of employees volunteered for the study on muscular back discomfort. The first group of 35 persons volunteered to participate in the EIP (EIP group), and the second 17 persons from Building B did not (non-EIP group). The EIP was composed of 4 major categories: (1) engineering improvement, (2) change in personal protective equipment, (3) environmental improvement, (4) administrative intervention, training, and health education. Low back muscular discomfort was measured through questionnaires on subjective feelings of muscular discomfort, and by surface electromyography (sEMG). Muscle activities were measured by sEMG of the left and right erector spinae and multifidus muscles, and evaluated by multivariate test for dependent samples (paired observation), and multivariate test for two independent samples. After EIP, IFR decreased 65.46%, ISR decreased 41.02%, and medical expenses decreased 42.79%. The low back muscular loads of the EIP group were significantly reduced, with a 95% confidence level (p < 0.05) while those of the non-EIP group were not. Subjective feelings of muscular discomfort, determined by Wilcoxon Signed Ranks test, showed that after applying the EIP to the EIP group, the mean scores for general bodily discomfort and low back muscular discomfort in the EIP group had significantly reduced, while those of the non-EIP group increased, (p < 0.05).

    This study was conducted to develop and to test the effects of an educational program for coping with problem situations as a nursing intervention in the diabetic patient. A non-equivalent control group pretest-posttest design was used in this study. Data were collected from January to March, 2002. The subjects of the study consisted of 31 diabetic patients(experimental group: 17 patients, control group: 14 patients). The intervention of an educational program for coping with problem situations was applied to the experimental group for 4 weeks (total 8 hours). Data were collected before the educational program, immediately after and 1 months later and were analyzed with repeated measures ANOVA, t-test, and paired t-test. 1. There was a significant difference in self efficacy between the experimental and control groups (F=13.793, p=0.001). 2. There was a significant difference in self care behavior between the experimental and control groups (F=4.583, p=0.041). 3. There was a significant difference in coping behavior of the problem situation between the experimental and control groups (F=62.018, p=0.000). There was a significant difference according to experimental stages (F=4.546, p=0.015) and interaction between education and experimental stages (F=12.039, p=0.000). 4. There was a significant difference in glycemic control between the experimental and control groups (t=-3.112, p=0.004). These results support that a diabetic educational program for coping with problem situations is effective in promoting and maintaining self efficacy, self care behavior, problem coping behaviors and in improving glycemic control. Thus this program can be recommended as an effective nursing intervention of in-depth education for diabetic patient.

    To examine the long-term effects of foot-bathing therapy, using different water temperatures, on the sleep quality of older adults living in nursing homes. A quasi-experimental study design with non-equivalent control group. Thirty participants were recruited from a nursing home in Gyeong-gi Province, South Korea. The participants were randomly assigned to experimental, placebo, and control groups. The foot-bathing therapy was performed for 30min daily for four weeks. Water at 40°C was used for the experimental group, while water at 36.5°C was used for the placebo group. The control group did not receive any intervention. The participants' sleep patterns (total sleep amount, sleep efficiency, and sleep latency) and sleep-disturbed behaviors were compared based on group, using actigraphy and a sleep disorder inventory. The total amount of sleep and sleep efficiency were significantly different for the experimental group, especially those with poor sleep quality. There were no differences in sleep latency or sleep-disturbed behaviors among the groups. The long-term effect of the therapy decreased in the third week of the therapy. Daily, 30-min foot-bathing therapy sessions with water at 40°C were effective in improving sleep quality for older adults. The therapy was more effective for participants with poor sleep quality at baseline assessment than those with relatively good sleep quality. The long-term effects of foot-bathing therapy decreased three weeks after initiation; therefore, it might be desirable to deliver the therapy for two weeks, pause it for a week, and then resume it.

    Difficulties with bathing are frequent among older people and are associated with an increasing need for societal support. As loss of independence has a negative impact on health and wellbeing, it is important to study interventions that can provide the required support for people to be able to remain independent. Occupational therapy interventions can improve clients' abilities enabling them to bathe themselves, thus reducing the need for other, more long-term societal support from, e.g. a home help. In this study, two groups of elderly people with difficulties in bathing were compared; the clients in the intervention group were engaged in occupational therapy. A quasi-experimental non-equivalent control group design was used, in which participants with reported difficulties in bathing were recruited consecutively from two municipalities. The clients in the intervention group routinely received occupational therapy, whereas clients in the control group received assistance from a home help for bathing. Activities of daily living, quality of life and home-help allocation were assessed at the baseline and after 15 weeks. Clients in the intervention group received less than three home visits on average, with majority of interventions consisting of graded activity and the use of an encouraging approach. Seventy per cent of the interventions were adaptive. Activities of daily living and quality of life of both groups improved, but the differences of being allocated a home help were significant. Occupational therapy interventions seem beneficial in terms of supporting older people in becoming independent of home help in bathing but the results must be interpreted with caution as there were differences at baseline between the groups. © 2011 The Authors.

    To investigate the clinical impact of a brief transition programme for young people with JIA. The Devices for Optimization of Transfer and Transition of Adolescents with Rheumatic Disorders (DON'T RETARD) project is a mixed method project in which we first conducted a quasi-experimental study employing a one-group pre-test-post-test with a non-equivalent post-test-only comparison group design. In this quantitative study, we investigated clinical outcomes in patients with JIA and their parents who participated in the transition programme (longitudinal analyses). The post-test scores of this intervention group were compared with those of patients who received usual care (comparative analyses). Second, a qualitative study was conducted to explore the experiences of adolescents with JIA and their parents regarding their participation in the transition programme. The primary hypothesis of improved physical (effect size 0.11), psychosocial (effect size 0.46) and rheumatic-specific health status (effect size ranging from 0.21 to 0.33), was confirmed. With respect to the secondary outcomes, improved quality of life (effect size 0.51) and an optimized parenting climate (effect size ranging from 0.21 to 0.28) were observed. No effect was measured in medication adherence (odds ratio 1.46). Implementation of a transition programme as a brief intervention can improve the perceived health and quality of life of adolescents with JIA during the transition process, as well as the parenting behaviours of their parents. Based on the present study, a randomized controlled trial can be designed to evaluate the effectiveness of the transition programme. © The Author 2015.

    Context: Gratitude intervention is expectedly an effective intervention to reduce depression and improve the quality of life in schizophrenic patients, but there is a lack of literature on it. Aims: We attempted to develop and test the effectiveness of the gratitude disposition promotion program for chronic schizophrenic patients in Korea. Settings and Design: Nonequivalent control group pre- and post-test design was used in two mental health centers located at Gyeonggi-do in South Korea. Materials and Methods: This paper was a quasi-experimental study and the participants who took part in the gratitude disposition promotion program were 17 of experimental group and 15 of control group. Gratitude disposition (the short gratitude, resentment, and appreciation test), depression (Beck Depression Inventory), and quality of life (developed by Kook) of chronic schizophrenic patients were measured before and after an intervention, as compared to the control. Statistical Analysis: Chi-square test, Fisher's exact test, and t-test were performed for prehomogeneity testing for variables related to the general characteristics. Testing for the effectiveness of gratitude disposition promotion program and hypothesis testing for its effect on depression and quality of life were by ANCOVA and t-test, as verified to significance level of P < 0.05. Results: The participants who received the gratitude disposition promotion program showed significant improvements in gratitude disposition (F = 18.740, P < 0.0001) and in quality of life (F = 9.800, P = 0.004), but no significant difference in depression (F = 3.870, P = 0.059). Conclusions: The gratitude disposition promotion program was an effective clinical intervention program for enhancing gratitude disposition and quality of life of chronic schizophrenic patients in community.

  8. A crystallographic model for hydrous wadsleyite (Beta-Mg2SiO4)

    1994-01-01

    Wadsleyite (beta-Mg2SiO4) is believed to be the most abundant phase in the Earth between depths of 400 and about 525km. Because of the unusual crystal chemistry, Smyth suggested that this phase might be a significant host for hydrogen in the transition zone. Indeed, of the nominally anhydrous phases believed to make up the upper mantle and transition zone none has been reported with a greater H content than wadsleyite. Young et al, report the synthesis of hydrous, Fe-bearing wadsleyite with up to 60,000 H per 10(exp 6) Si. Using ionic constraints and maximal subgroup symmetry, a hypothetical, ordered model for hydrous wadsleyite has been created and examined. The model has formula Mg7Si4O14(OH)2, has space group Pmmb, has an ordered vacancy into one of two non-equivalent M2 sites, and contains two different H positions, one on each of the non-equivalent O1 sites. Electrostatic calculations indicate that hydration would relieve the underbonding of O1 as well as the overbonding of the bridging oxygen, O2, so that the hydrous phase may be more stable than the anhydrous phase. This model makes several predictions that may be of significance for the mechanisms and amounts of H that may be stored in the transition zone of the Earth, and by which the model may be tested experimentally.

    Low-income youth experience social-emotional problems linked to chronic stress that are exacerbated by lack of access to care. Drumming is a non-verbal, universal activity that builds upon a collectivistic aspect of diverse cultures and does not bear the stigma of therapy. A pretest-post-test non-equivalent control group design was used to assess the effects of 12 weeks of school counselor-led drumming on social-emotional behavior in two fifth-grade intervention classrooms versus two standard education control classrooms. The weekly intervention integrated rhythmic and group counseling activities to build skills, such as emotion management, focus and listening. The Teacher's Report Form was used to assess each of 101 participants (n = 54 experimental, n = 47 control, 90% Latino, 53.5% female, mean age 10.5 years, range 10–12 years). There was 100% retention. ANOVA testing showed that intervention classrooms improved significantly compared to the control group in broad-band scales (total problems (P < .01), internalizing problems (P < .02)), narrow-band syndrome scales (withdrawn/depression (P < .02), attention problems (P < .01), inattention subscale (P < .001)), Diagnostic and Statistical Manual of Mental Disorders-oriented scales (anxiety problems (P < .01), attention deficit/hyperactivity problems (P < .01), inattention subscale (P < .001), oppositional defiant problems (P < .03)), and other scales (post-traumatic stress problems (P < .01), sluggish cognitive tempo (P < .001)). Participation in group drumming led to significant improvements in multiple domains of social-emotional behavior. This sustainable intervention can foster positive youth development and increase student-counselor interaction. These findings underscore the potential value of the arts as a therapeutic tool.

    To investigate the effects of using intra and extra circumoral exercise on subjective and objective parameters of pre- and postoral health of older people living in nursing homes. Oral health problems, such as dry mouth and halitosis, are very common complaints for older people and might be the cause of a physiological, psychological or social handicap. In an ageing society, a simple and convenient nursing intervention is needed to resolve these oral health problems without side effects. The present study adopted a pre- and posttest non-equivalent control group in a quasi-experimental design. A total of 41 older people (experimental group 21, control group 20) living in nursing homes participated in intra and extra circumoral exercise (25 min a day, six times per week for 4 weeks) to improve oral health in 2013. Chi-square test/Fisher's exact test, t-test/Mann-Whitney U-test and analysis of covariance were used for the data analysis. ancova was used to control the covariates (age and the basic values of dependent variables) to identify the effect of intra and extra circumoral exercise on the oral health between the two groups. Dry mouth symptoms decreased, oral motor function improved, salivary secretion and mouth opening size increased, salivary pH improved, halitosis decreased more in the experimental group than in the control group. However, the salivary IgA was not significantly different between the two groups. The intra and extra circumoral exercises as an independent nursing intervention can effectively promote oral health of older people. © 2016 John Wiley & Sons Ltd.

Many breastfeeding mothers are reticent to increase their dose or consider additional medication, despite incomplete response, due to potential adverse effects on their newborn. These mothers are amenable to non-pharmacological intervention for complete symptom remission. The current study evaluated the feasibility of an eight-week mindfulness-based cognitive therapy (MBCT) intervention as an adjunctive treatment for postpartum depression and anxiety. Women were recruited at an outpatient reproductive mental health clinic based at a maternity hospital. Participants had a diagnosis of postpartum depression/anxiety within the first year following childbirth. They were enrolled in either the MBCT intervention group (n = 14) or the treatment-as-usual control group (n = 16), and completed the Patient Health Questionnaire-9 (PHQ-9), the Generalized Anxiety Disorder-7 (GAD-7) questionnaire, and the Mindful Attention Awareness Scale (MAAS) at baseline and at 4 weeks, 8 weeks, and 3 months following baseline. Multivariate analyses demonstrated that depression and anxiety levels decreased, and mindfulness levels increased, in the MBCT group, but not in the control group. Many of the between-group and over time comparisons displayed trends towards significance, although these differences were not always statistically significant. Additionally, the effect sizes for anxiety, depression, and mindfulness were frequently large, indicating that the MBCT intervention may have had a clinically significant effect on participants. Limitations include small sample size and the non-equivalent control group design. We demonstrated that MBCT has potential as an adjunctive, non-pharmacological treatment for postpartum depression/anxiety that does not wholly remit with pharmacotherapy. (249 words).

    The aims of this study were to develop a motivational interviewing program for exercise improvement in persons with physical disabilities and to examine the effect of this motivational interviewing intervention. The study employed a nonequivalent control group pretest and posttest design. A total of 62 persons with physical disabilities (30 in the experimental group, 32 in the control group) were recruited from 2 community rehabilitation centers. The experimental group received 8 sessions of a group motivational interviewing program, scheduled once a week, with each session lasting 60 minutes. Test measures were completed before the intervention, immediately after the end of the intervention, 2 weeks later, and 6 weeks after the end of the intervention. Measures included self-efficacy for exercise, decisional balance for exercise, stage of change for exercise, regularity of exercise, exercise maintenance, and independent living ability. Data were analyzed using the χ²-test, Fisher's exact test, Independent samples t-test, and repeated measures ANOVA, conducted using IBM SPSS Statistics version 18. The experimental group showed a significant increase in self-efficacy for exercise (F=50.98, p<.001), benefit (pros) of exercise (F=24.16, p<.001), and independent living ability (F=50.94, p<.001), and a significant decrease in loss (cons) of exercise (F=26.50, p<.001). There were significant differences between the two groups in stages of change for exercise (p<.001), regularity of exercise (p<.001), and exercise maintenance (χ²=26.61, p<.001). The motivational interviewing program has the potential to improve exercise levels in persons with physical disabilities. © 2017 Korean Society of Nursing Science

    To investigate the effects of a suicide prevention programme on the levels of depression, self-esteem, suicidal ideation and spirituality in patients with mental illness. Instances of suicide have significant correlations with depression, low self-esteem, suicidal ideation and a low level of spirituality in the victims. Therefore, addressing depression, low self-esteem and suicidal ideation as suicide risk factors and increasing levels of spirituality can constitute an effective programme to prevent suicide among patients with mental illness. The study was a quasi-experimental study with a nonequivalent control group, nonsynchronised design. The study sample consisted of 45 patients with mental illness who had been admitted to the psychiatric unit in a university hospital in South Korea. The patients were assigned to control and experimental groups of 23 and 22 members, respectively. The suicide prevention programme was conducted with the experimental group over four weeks and included eight sessions (two per week). The control group received only routine treatments in the hospital. The experimental group that participated in the programme had significantly decreased mean scores for depression and suicidal ideation compared with the control group. However, there were no significant differences in the mean scores for self-esteem and spirituality between the groups. The suicide prevention programme might be usefully applied as a nursing intervention for patients hospitalised in psychiatric wards or clinics where the goals are to decrease depression and suicidal ideation. Typical treatments for hospitalised patients with mental illness are not enough to prevent suicide. Intervention for suicide prevention needs to apply an integrated approach. The suicide prevention programme using an integrated approach is more effective in reducing depression and suicidal ideation in patients with mental illness than applying routine treatments in the hospital. © 2013 John Wiley & Sons Ltd.

    Students seeking degrees in healthcare in Ecuador participate in community improvement projects and provide free health services under the supervision of faculty health professionals. The aim of this study is to determine the impact of a community-based intervention delivered by nursing students on health-related quality of life (HRQoL) and perceived social support of a rural population in Ecuador. A quasi-experimental non-equivalent control group design study was conducted in two rural communities in Tumbaco, Ecuador. Families from one rural community were invited to participate in the intervention, receiving 8 weekly home visits from nursing students. Families from a neighboring community were similarly recruited as wait-list controls. One member of each family was consented into the study; the final sample included 43 intervention participants and 55 control participants. HRQoL and perceived social support were assessed before and after the intervention in both groups. The SF-12 was used to measure HRQoL, including eight domain scores and two composite scores, and the Interpersonal Support Evaluation List was used as an indicator of perceived social support. Difference-in-differences (DD) analyses were conducted to mitigate the effects of any baseline differences in the non- equivalent control group design. When compared to the control group, the intervention group realized significant improvements in the physical component summary score of the SF-12 (4.20, p < 0.05) and the physical function domain of the SF-12 (4.92, p < 0.05). There were no statistically significant differences for any other components of the SF-12 or in the measure of perceived social support. Nursing students completing their rural service rotation have the potential to improve the health-related quality of life of rural residents in Ecuador. Future research should continue to examine the impact of service-based learning on recipient populations.

    Immigrants with cancer often have professional and/or family interpreters to overcome challenges communicating with their health team. This study explored the rate and consequences of nonequivalent interpretation in medical oncology consultations. Consecutive immigrant patients with newly diagnosed with incurable cancer, who spoke Arabic, Cantonese, Mandarin, or Greek, were recruited from the practices of 10 medical oncologists in nine hospitals. Their first two consultations were audio taped, transcribed, translated into English and coded. Thirty-two of 78 participants had an interpreter at 49 consultations; 43% of interpreters were family, 35% professional, 18% both a professional and family, and 4% a health professional. Sixty-five percent of professional interpretations were equivalent to the original speech versus 50% for family interpreters (P= .02). Seventy percent of nonequivalent interpretations were inconsequential or positive; however, 10% could result in misunderstanding, in 5% the tone was more authoritarian than originally intended, and in 3% more certainty was conveyed. There were no significant differences in interpreter type for equivalency of interpretations. Nonequivalent interpretation is common, and not always innocuous. Our study suggests that there may remain a role for family or telephone versus face-to-face professional interpreters. careful communication between oncologists and interpreters is required to ensure optimal communication with the patient.

    The value of dissection as an instructional strategy has been debated, but not evidenced in research literature. The purpose of this study was to examine the efficacy of using computer simulated frog dissection as a substitute for traditional hands-on frog dissection and to examine the possible enhancement of achievement by combining the two strategies in a specific sequence. In this study, 134 biology students at two Central Texas schools were divided into the five following treatment groups: computer simulation of frog dissection, computer simulation before dissection, traditional hands-on frog dissection, dissection before computer simulation, and textual worksheet materials. The effects on achievement were evaluated by labeling 10 structures on three diagrams, identifying 11 pinned structures on a prosected frog, and answering 9 multiple-choice questions over the dissection process. Attitude was evaluated using a thirty item survey with a five-point Likert scale. The quasi-experimental design was pretest/post-test/post-test nonequivalent group for both control and experimental groups, a 2 x 2 x 5 completely randomized factorial design (gender, school, five treatments). The pretest/post-test design was incorporated to control for prior knowledge using analysis of covariance. The dissection only group evidenced a significantly higher performance than all other treatments except dissection-then-computer on the post-test segment requiring students to label pinned anatomical parts on a prosected frog. Interactions between treatment and school in addition to interaction between treatment and gender were found to be significant. The diagram and attitude post-tests evidenced no significant difference. Results on the nine multiple-choice questions about dissection procedures indicated a significant difference between schools. The interaction between treatment and school was also found to be significant. On a delayed post-test, a significant difference in gender was found on the diagram labeling segment of the post-test. Males were reported to have the higher score. Since existing research conflicts with this study's results, additional research using authentic assessment is recommended. Instruction should be aligned with dissection content and process objectives for each treatment group, and the teacher variable should be controlled.

  17. Design of the DISCovery project: tailored work-oriented interventions to improve employee health, well-being, and performance-related outcomes in hospital care

    Background It is well-known that health care workers in today’s general hospitals have to deal with high levels of job demands, which could have negative effects on their health, well-being, and job performance. A way to reduce job-related stress reactions and to optimize positive work-related outcomes is to raise the level of specific job resources and opportunities to recover from work. However, the question remains how to translate the optimization of the balance between job demands, job resources, and recovery opportunities into effective workplace interventions. The aim of the DISCovery project is to develop and implement tailored work-oriented interventions to improve health, well-being, and performance of health care personnel. Methods/Design A quasi-experimental field study with a non-equivalent control group pretest-posttest design will be conducted in a top general hospital. Four existing organizational departments will provide both an intervention and a comparison group. Two types of research methods are used: (1) a longitudinal web-based survey study, and (2) a longitudinal daily diary study. After base-line measures of both methods, existing and yet to be developed interventions will be implemented within the experimental groups. Follow-up measurements will be taken one and two years after the base-line measures to analyze short-term and long-term effects of the interventions. Additionally, a process evaluation and a cost-effectiveness analysis will be carried out. Discussion The DISCovery project fulfills a strong need for theory-driven and scientifically well-performed research on job stress and performance interventions. It will provide insight into (1) how a balance between job demands, job resources, and recovery from work can be optimized, (2) the short-term and long-term effects of tailored work-oriented effects, and (3) indicators for successful or unsuccessful implementation of interventions.

    Background: Argumentation is accepted by many science educators as a major component of science education. Many studies have investigated students' conceptual understanding and their engagement in argumentative activities. However, studies conducted in the subject of chemistry are very rare. Purpose: The present study aimed to investigate the effects of argumentation-based chemistry lessons on pre-service science teachers' understanding of reaction rate concepts, their quality of argumentation, and their consideration of specific reaction rate concepts in constructing an argument. Moreover, students' perceptions of argumentation lessons were explored. Sample: There were 116 participants (21 male and 95 female), who were pre-service first-grade science teachers from a public university. The participants were recruited from the two intact classes of a General Chemistry II course, both of which were taught by the same instructor. Design and methods: In the present study, non-equivalent control group design was used as a part of quasi-experimental design. The experimental group was taught using explicit argumentation activities, and the control group was instructed using traditional instruction. The data were collected using a reaction rate concept test, a pre-service teachers' survey, and the participants' perceptions of the argumentation lessons questionnaire. For the data analysis, the Wilcoxon Signed Rank Test, the Mann-Whitney U-test and qualitative techniques were used. Results: The results of the study indicated that an argumentation-based intervention caused significantly better acquisition of scientific reaction rate-related concepts and positively impacted the structure and complexity of pre-service teachers' argumentation. Moreover, the majority of the participants reported positive feelings toward argumentation activities. Conclusions: As students are encouraged to state and support their view in the chemistry classroom when studying reaction rate, it was observed that their understanding increased in terms of both the context and the quality of the argumentation that they produced. In light of the findings, it is suggested that argumentation activities should be developed to promote students' science content knowledge and argumentation skills.

    In this paper, we study the magnetic properties of a ferromagnetic bi-layer graphene structure with non-equivalent planes. The geometry of the studied system is formed by two layers (A) and (B) consisting of the spins σ = 1 / 2 and S = 1 . For this purpose, the influence of the coupling exchange interactions, the external magnetic and the crystal fields are investigated and presented as well as the ground state phase diagrams. The Monte Carlo simulations have been used to examine the behavior of the partial and the total magnetizations as a function of the system parameters. These effects on the compensation and critical temperatures behavior are also presented in different phase diagrams, for the studied system.

    Nursing students' interest in older people nursing needs to be enhanced, as there is a demand for competent nurses who prefer to work in older people nursing. Educational approaches involving older people are encouraging; they increase positive learning outcomes. The aim of this study was to evaluate the outcomes of the Learning with Older People Programme (LOPP) in terms of nursing students' interest in older people nursing, their attitudes towards older people and their knowledge level about ageing. A quasi-experimental, pre-post-test design with non-equivalent comparison group was used. Two different Finnish nursing schools geographically apart from each other. A nonprobability, convenience sample of nursing students (n=87; n=46 in the intervention group, n=41 in the comparison group) in the middle of their 3.5 year bachelor degree studies and enrolled in compulsory theoretical older people nursing courses participated in the study. Data were collected in 2014 using a structured questionnaire that included background questions, students' interest in older people nursing as a primary outcome measure and their attitudes towards older people and knowledge level about ageing as secondary outcome measures. The data were analysed statistically. In the intervention group, students' interest in older people nursing was significantly higher and their attitudes towards older people were more positive than those of students in the comparison group. There were no significant differences between the groups in terms of the students' knowledge level about ageing. An educational approach involving older people resulted in encouraging outcomes. It is worth considering whether or not older people could be a valuable resource for nursing education. Copyright © 2015 Elsevier Ltd. All rights reserved.
