Objectives: This article presents a systematic evaluation of the effectiveness of interventions aimed at reducing distress in adult victims of rape and sexual violence. Method: Studies were eligible for the review if the assignment of study participants to experimental or control groups was by random allocation or parallel cohort design. Results:…

This article reviews several decades of the author's meta-analytic and experimental research on the conditions under which nonrandomized experiments can approximate the results from randomized experiments (REs). Several studies make clear that we can expect accurate effect estimates from the regression discontinuity design, though its statistical…

Objective: To assess the impact of treatment foster care (TFC) on psychosocial and behavioral outcomes, delinquency, placement stability, and discharge status for children and adolescents who, for reasons of severe medical, social, psychological and behavioural problems, were placed in out-of-home care in restrictive settings or at risk of…

Method: A total of 119 studies were subjected to a meta-analysis. Targeted outcomes included substance use (tobacco, alcohol, drugs, marijuana), health-related behaviors (diet,…

Objectives: To evaluate the impact of school-based mentoring for adolescents (11-18 years) on academic performance, attendance, attitudes, behavior, and self-esteem. Method: A systematic review and meta-analysis. The authors searched 12 databases from 1980 to 2011. Eight studies with 6,072 participants were included, 6 were included in…

Objective: The present study identifies and summarizes treatment effects for children and adolescent conduct problems based on accrued meta-analytic studies. Method: Systematic search and coding procedures were used to summarize studies from 1980 to 2007. Results: A total of 26 meta-analytic reviews composed of nearly 2,000 studies revealed…

Objective: To investigate the impact of forgiveness interventions designed to help individuals who have suffered because of betrayals, offenses, or victimization. Forgiveness is believed to be a mechanism through which individuals can experience increases in hope and positive emotions and relief from negative emotions, cognitions, and behaviors.…

This article elaborates on the centrality of interventions for social work practice and the importance of understanding the effects of interventions for a more efficient, harmless, transparent, and ethical social work practice. Low-bias research designs and meta-analyses are important means of generating the best possible evidence on what works in…

Since 1983, the Washington State Institute for Public Policy has conducted applied research as a nonpartisan agency of the state legislature. Over the years, discussions in the state have turned toward emphasizing "evidence-based" programs and policies in decision making, and research requests of the legislature have evolved to reflect…

Objective: The goal of this study is to advance an approach to the assessment of the quality of studies considered for inclusion in systematic reviews of the effects of social-care interventions. Method: To achieve this objective, quality is defined in relation to the widely accepted validity typology; prominent approaches to study quality…

Objective: A meta-analysis was conducted to evaluate the effectiveness of solution-focused brief therapy (SFBT). Method: Hierarchical linear modeling software was used to synthesize the primary studies to calculate an overall effect size estimate and test for between-study variability. Results: Solution-focused brief therapy demonstrated small but…
