hypotheses. First, we hypothesized that CBT would outperform comparison conditions. Second we hypothesized that SRIs would outperform comparison conditions. Finally, given the variable findings across moderators in individual RCTs, the association between purported moderators and treatment effects were explored across interventions. Although the efficacy of combined treatment (e.g., CBT+SRI) for pediatric OCD has some empirical support,[19; 56; 57] this treatment modality was considered too preliminary for inclusion in the current meta-analyses due to the limited number of published RCTs. Direct comparison trials of CBT and SRIs were also not examined due to their recent meta-analytic evaluation.[58] In this meta-analysis, Romanelli and colleagues[58] found that CBT outperformed SRIs across RCTs of youth and adults (effect size=0.37), but found no significant difference between CBT and CBT+SRI conditions.
