Abstract

Background and Aims: With an occurrence of 8-11%, anxiety disorder relapse is somewhat common in children and young people (CYP). Although no variables were found consistent predictors of anxiety relapse so far, pretreatment anxiety severity (PAS) and posttreatment depression severity (PDS) were most often identified by previous research. The current study therefore aims to reinvestigate whether PAS and PDS can be used to predict anxiety relapse in CYP after successful CBT. Both significant main effects as well as a significant moderation effect of PAS and PDS were hypothesized. Method: A systematic search for studies in English on CYP focusing on anxiety disorder treatment resulted in 155 unique studies after two screenings. Data of 33 studies were prepared for the analysis. A final sample of 214 remitted CYP compiled from 8 studies, aged 5-18, 51% male, all initial responders to CBT after an anxiety diagnosis, was analyzed via an individual participant data meta-analysis (IPDMA). Results: The relapse rate in the sample was 17.8%. A binary logistic regression analysis performed on 214 cases showed insignificant results regarding the predictive power of either predictor as well as moderation. Conclusion and implications: The results suggest that relapse may not be easily predicted, low observed power may have contributed to this result however. Therefore, post-treatment relapse prevention interventions are recommended to target CBT-completers in general. Future research with a larger IPDMA dataset may give more conclusive findings.
