The main goal of the study is to evaluate the effectiveness of a universal depression prevention program ‘Op Volle Kracht’ (OVK) for young adolescents (12-14 years) in decreasing depressive symptoms and enhancing resilience in youth. This was done by conducting a randomized controlled trial with two conditions, an intervention and control group. The prevention program OVK is based on the Penn Resiliency Program (PRP). PRP is a cognitive behavioral program and was found to be effective in the USA in reducing depressive symptoms and feelings of hopelessness. In addition, adolescents who completed PRP had a more positive way of thinking and obtained higher grades in school. In the current project the effectiveness of OVK as depression prevention program and resiliency program will be evaluated.
- Examine the effectiveness of OVK as universal depression prevention
- Examine the effectiveness of OVK as a resiliency training in preventing hopelessness, anxiety and promoting optimism, happiness, self-efficacy and coping
- Study the mediating mechanisms of the intervention effect
- Study the association between self-efficacy and depressive symptoms over time
- Analyze the association between coping and depressive symptoms during adolescence
- Study the role of cognitions, self-efficacy and life events in the development of depressive symptoms during adolescence
Since OVK was not effective in preventing depressive symptoms and promoting positive development (happiness, self-efficacy, coping), the mediating mechanisms of the intervention effectiveness could not be studied. Therefore, more attention was directed at the development of depressive symptoms during adolescence and the association with self-efficacy, coping and cognitive errors.
