Abstract
BACKGROUND AND OBJECTIVES: This two-year follow-up study evaluated the long-term outcomes of two early interventions that aimed at reducing social and test anxiety in young adolescents at risk for developing social anxiety disorder. METHODS: In this RCT, moderately socially anxious adolescents (N=240, mean age 13.6 years) were randomly assigned to a 10-week internet-based multifaceted cognitive bias modification training (CBM), a 10-week school-based cognitive behavioral group training (CBT), or a no-intervention control condition. Using multiple imputation, this study examined the changes in primary and secondary outcome measures from pretest to follow-up in a repeated measures design. RESULTS: Primary outcome: Self-reported social and test anxiety generally decreased from pre-test to two-year follow-up, regardless of treatment condition. The percentage of adolescents who developed a social anxiety disorder was very low (6%) and similar across conditions. Secondary outcome: There were beneficial changes in self-esteem, self-reported prosocial behaviors, and fear of negative evaluation, but none of these were related to treatment condition. Automatic social-threat associations did not significantly change. The CBM intervention was effective in changing interpretative bias as indexed by the Recognition Task but this long-term effect did not transfer to the Adolescent Interpretation and Belief Questionnaire. LIMITATIONS: There was a substantial (50%) though seemingly non-selective attrition at follow-up. CONCLUSIONS: This RCT does not support the longer-term efficacy of school-based CBT or CBM as an early intervention for social and test anxiety. Rather, it emphasizes the positive 'natural' course of highly socially anxious adolescents over two years.
