Pilot Evaluation Study of the Life Skills Program REBOUND

The main aim of the study is pilot evaluation of the life skills program REBOUND in a school context focusing on substance use, risk perception, and knowledge about psychoactive substances (nIG+CG = 723 students in five schools and 46 classes, Mage = 14.8, range 14-18) for the total sample and in the subgroups gender, age, and school type. Main goal of the study is collecting evidence for program optimization. A controlled study was carried out with repeated measurement before and after the intervention (4-6 months). Multilevel analyses, ANCOVA, and logistic regression analyses were applied to measure the effects. Overall, significantly lower incidence rates of drunkenness (odds ratio [OR] = .55; p = .033), improved knowledge about psychoactive substances (p = .006), lower personal (p = .013) and general tobacco risk perception among users (p = .002), and lower general tobacco (p = .018) and cannabis (p = .000) risk perception in non-users were found in the total intervention group. In subgroups, signific...
