Given the significant difference between comparison interventions, moderator analyses were conducted separately on CBT trials using non-active and active comparison conditions. Table 3 presents the results of moderator analyses across all three outcome types. For non-active comparison conditions, there was a positive association between the percentage of youth with co-occurring anxiety disorders and ES for treatment efficacy and response, with trials that had participants with more co-occurring anxiety disorders exhibiting larger ES. Additionally, for treatment efficacy and symptom remission, there was a positive association between the number of therapeutic hours and ES, with trials that had greater therapeutic contact exhibiting larger ES. Furthermore, there was an association between active treatment attrition and ES for treatment efficacy, with trials exhibiting greater attrition yielding lower ES. There was no significant difference between non-active comparison CBT trials that emphasized ERP relative to CT for treatment efficacy (g=1.52 vs. 1.41), treatment response (RR=5.50 vs. 3.67), or symptom diagnostic/remission (RR=6.69 vs. 4.47). There were no other significant moderators of treatment efficacy, treatment response, or symptom/diagnostic remission among non-active comparison trials. Table 3 also presents moderator
