A large body of literature exists related to parent-implemented interventions for children with disabilities, so it is helpful to synthesize the results of outcome-based interventions for children with developmental disabilities. Specifically, what are the effects of parent-implemented interventions intended to improve childrens (1) social behaviors, (2) life skills/adaptive behavior, and (3) communication skills? Using meta-analytic aggregation of effect sizes across 30 studies with a total of 1,356 participants, this review examined the association between parent-implemented interventions and intended outcomes for young children with developmental disabilities. Across all 30 studies comparing childrens outcomes to control groups, the random-effects-weighted average effect size was d = 0.495 (95% confidence interval = 0.31 to 0.68). Effect sizes ranged from d = -0.28 to 3.23, with the index of heterogeneity reaching statistical significance (Q (29) = 72.0, p < .001; I2 = 59.7%). The overall results were not moderated by the four participant characteristics evaluatedage, gender, socioeconomic status (SES), and disability. All parent-implemented interventions resulted in child outcomes that were statistically significantly better than the control group. Interventions targeting communication skills resulted in the greatest relative gains, and interventions targeting life skills/adaptive behavior resulted in the smallest relative gains (yet statistically better than the control group). Findings indicate clinical benefits when professionals include parents in interventions intended to influence the socialbehavioral, communication, and adaptive development of young children with developmental disabilities.

There is a paucity of research on the mental health of Pacific Islanders living in the United States, including those of Polynesian descent. This study examined coping strategies, attitudes toward seeking mental health counseling, public and self-stigma toward seeking mental health services, and
psychological adjustment among 638 Polynesian Americans. On average, participants held neither favorable nor unfavorable attitudes toward seeking professional psychological help, but men endorsed moderate self-stigma
about mental illness and women endorsed high levels of public stigma about mental illness. Women showed relatively more favorable attitudes than men about seeking help from professional mental health providers. Participants
reported benefitting more from culturally congruent practices for coping with distress (accepting, reframing, striving, family support, and religiosity/spirituality) than from seeking assistance from private emotional outlets
(e.g., therapy) or avoidance and detachment. Mental health professionals need to build cross-cultural bridges and culturally adapt services to address concerns among Polynesian Americans.

Although a large body of literature exists supporting the relationship between positive parenting and child outcomes for typically developing children, there are reasons to analyze separately the relevant literature specific to children with developmental disabilities. However, that literature has not been synthesized in any systematic review. This study examined the association between positive parenting attributes and outcomes of young children with developmental disabilities through meta-analytic aggregation of effect sizes across 14 studies including 576 participants. The random effects weighted average effect size was r = .22 (SE = .06, p < .001), indicative of a moderate association between positive parenting attributes and child outcomes. Publication bias did not appear to be a substantial threat to the results. There was a trend for studies with more mature parents to have effect sizes of higher magnitude than studies with young parents. The results provide support for efforts to evaluate and promote effective parenting skills when providing services for young children with disabilities.

This is a graduate level textbook for students in the biobehavioral and social sciences, introducing the major multivariate and modern regression methods that form the methodological core of research in those disciplines. The publication year is 2012, but it was released in December 2011.

There is a pressing need to enhance the availability and quality of mental health services provided to persons from historically disadvantaged racial and ethnic groups. Many previous authors have advocated that traditional mental health treatments be modified to better match clients' cultural contexts. Numerous studies evaluating culturally adapted interventions have appeared, and the present study used meta-analytic methodology to summarize these data. Across 76 studies the resulting random effects weighted average effect size was d = .45, indicating a moderately strong benefit of culturally adapted interventions. Interventions targeted to a specific cultural group were four times more effective than interventions provided to groups consisting of clients from a variety of cultural backgrounds. Interventions conducted in clients' native language (if other than English) were twice as effective as interventions conducted in English. Recommendations are provided for improving the study of outcomes associated with mental health interventions adapted to the cultural context of the client.

Children with autism spectrum disorder (ASD) have been shown to benefit from parent-implemented interventions (PIIs). This meta-analysis improved on prior reviews of PIIs by evaluating RCTs and multiple potential moderators, including indicators of research quality. Fifty-one effect sizes averaged moderately strong overall benefits of PIIs (g = 0.553), with studies having lower risk of research bias yielding lower estimates (g = 0.47). Parent and observer ratings yielded similar averaged estimates for positive behavior/social skills (g = 0.603), language/communication (g = 0.545), maladaptive behavior (g = 0.519), and to a lesser extent, adaptive behavior/life skills (g = 0.239). No other study, intervention, or participant characteristic moderated outcomes. PIIs with children with ASD tend to be effective across a variety of circumstances.
