Kraft, Matthew A. – Educational Researcher, 2023
It is a healthy exercise to debate the merits of using effect-size benchmarks to interpret research findings. However, these debates obscure a more central insight that emerges from empirical distributions of effect-size estimates in the literature: Efforts to improve education often fail to move the needle. I find that 36% of effect sizes from…

Washburn, Micki; Rubin, Allen; Zhou, Shu – Research on Social Work Practice, 2018
Purpose: This article provides benchmark data on within-group effect sizes from published randomized clinical trials supporting the efficacy of dialectical behavioral therapy (DBT) for borderline personality disorder (BPD) in adults aged 18-65 years. Method: Within-group effect sizes were calculated via the Glass approach and adjusted for sample…

Rubin, Allen; Yu, Miao – Research on Social Work Practice, 2017
This article provides benchmark data on within-group effect sizes from published randomized clinical trials that supported the efficacy of problem-solving therapy (PST) for depression among adults. Benchmarks are broken down by type of depression (major or minor), type of outcome measure (interview or self-report scale), whether PST was provided…

Stockard, Jean; Wood, Timothy W. – American Journal of Evaluation, 2017
Most evaluators have embraced the goal of evidence-based practice (EBP). Yet, many have criticized EBP review systems that prioritize randomized control trials and use various criteria to limit the studies examined. They suggest this could produce policy recommendations based on small, unrepresentative segments of the literature and recommend a…

Wing, Coady; Cook, Thomas D. – Journal of Policy Analysis and Management, 2013
The sharp regression discontinuity design (RDD) has three key weaknesses compared to the randomized clinical trial (RCT). It has lower statistical power, it is more dependent on statistical modeling assumptions, and its treatment effect estimates are limited to the narrow subpopulation of cases immediately around the cutoff, which is rarely of…
