Distribution of Effect Sizes (Cohen’s d) from Implementation Trials in Mental Health Settings.

Note. Sample size consisted of (n = 47) standard vs. Enhanced effect sizes and (n = 36) comparative effectiveness effect sizes. Standard vs. Enhanced designs consist of contrasts between a trial arm that receives one or more implementation strategies and a trial arm that receives all of the strategies in the other arm plus one or more additional strategies (e.g., distribute educational materials vs. Distribute educational materials + facilitation). Comparative effectiveness designs contrast trial arms with heterogeneous sets of implementation strategies (e.g., technical assistance vs. Facilitation).
