Primary Outcome Measures

Name	Time	Method
1. Depressive symptoms will be measured using the Quick Inventory of Depressive Symptomatology in Adolescents (Bernstein et al., 2010) via internet delivered self-rating forms pre-treatment, weekly during treatment and post-treatment.<br>1.1. In order to fully explore trajectories of change and possible moderating and mediating factors over time, a parallel process latent growth curve strategy will be employed.<br>2. Differences in efficacy between conditions will be investigated by modelling interaction effects of group and time.
