NettOpp: the Development and Evaluation of an App-based Selective Intervention for Adolescents Exposed to Cyberbullying

The main aim of the intervention is to increase coping strategies for adolescents who have been exposed to cyberbullying. More specifically the aims are to increase 1) knowledge about cyberbullying, 2) help‐seeking behavior, 3) coping strategies with cyberbullying, 4) to reduce mental health problems, and 5) cyberbullying, and 6) to increase self‐esteem and the 7) sleeping quality of the adolescents. To evaluate the mobile application three studies will be conducted: A lab test, a pilot study, and a larger effectiveness study with a follow‐up examination after 3 months. The lab test will be conducted to examine the quality of the prototype of the app in order to find out if adjustments have to be made. Thereafter, a pilot study will be conducted with adolescents that were exposed to cyberbullying in the past six months. The pilot study will use a pre‐post design.The effectiveness study will be conducted as a randomized controlled trial with an intervention group and a waiting‐list control group.
