Samenvatting

In this article a longitudinal effect study is described of resilience training Diamant. The training focuses in particular on adolescents with a dual identity who do not have work, are not enrolled in an education, feel unfairly treated (relatively deprived), have low self-esteem, and are at risk of social isolation. The training can be considered as a method to prevent development of criminal behaviour and possibly radicalisation. Certified trainers work with small groups of 10 to 15 adolescents to increase their resilience and help them finding their place in society. The present research focused on the following questions: (1) Does this training have a positive effect on self-esteem among the participants? (2) Does social isolation decrease as a consequence of the training? (3) Does the training reduce feelings of relative deprivation and help participants better deal with conflicts? Participants were interviewed before and halfway the training and directly after completing the training. A follow-up measurement three months after the end of the training examined effects on the longer term. In total 44 semi-structured interviews were held. Interviews were written out and coded using a two-step procedure: In the first step two researchers independently coded each interview. Second, when necessary, changes in the coding scheme were made. Then each interview was coded separately by the two researchers and disagreements were discussed until full agreement was reached. The results show that Diamant has a positive effect on self-esteem of participants. Also, participants overall showed an increase in connectedness to society. Third, Diamant reduced feelings of relative deprivation and participants indicated they could better deal with conflicts. Based on these results it is concluded that Diamant is effective in regard to its goals which were evaluated in this study. Limitations of the research and possibilities for future studies are discussed.
