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.

Research Goals:

  • 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

Recent developments:
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.
