Kids Beat Anxiety - KiBA III

The KiBA III study of principal investigator Anke Klein is a multicenter randomized controlled trial investigating the effect of adding a personalized app-based maintenance program after One-Session Treatment. Additionally, possible underlying mechanisms and predictors of treatment outcome are investigated.

In this study, 174 children aged 7-14 receive a one-session exposure treatment in which the therapist will help them to gradually approach the feared subject or situation. In the maintenance program condition, children will receive a mobile app with personalized exercises to help them practice for four weeks after treatment. In the treatment as usual condition, children are encouraged to keep practicing at home after treatment, but will not receive the app to assist them with this. The main goal of this study is to investigate whether the app-based maintenance program enhances short- and long-term treatment outcomes.

A secondary goal of the study is to investigate underlying mechanisms of treatment, including self-efficacy, cognitive biased, habituation and expectation violation and extinction learning. Furthermore, possible predictors of treatment outcome will be explored, by examining child and family factors. The study will be conducted in four different treatment centers, three in the Netherlands and one in Germany.
