The project focuses on the evaluation and implementation of a Skills4Life teaching program that is tailored to students in preparatory vocational education. To evaluate the program, questionnaires were completed by students to measure outcomes on social-emotional skills and psychosocial variables. For the evaluation, 2 qualitative studies were conducted, based on a quasi-experimental and a cross-sectional design. Crosstabs, Chi-square, ANOVA, Correlation and Multi-level analyses were used for the analyses of the evaluation study. Correlation, Backward regression and Mediation analyses were used for the analyses of the cross-sectional study.
