The study follows a two-arm RCT (n=34). The effects of a brief online psychoeducation program will be compared, with a waiting-list control group. The intervention aims to reduce feelings of trauma-related shame and guilt that adolescents experience regarding their own defense responses during and after (sexual) violence. Assessments take place after screening, at baseline, two weeks after allocation to the intervention or waiting-list, and, only for the waiting-list participants, seven weeks after allocation to the intervention.
