Experiencing cyberbullying and negative incidents online can negatively affect adolescents' mental health and well-being. NettOpp is a mobile application aiming to reduce the harmful effects of cyberbullying and negative incidents online on mental health outcomes. To evaluate the effect of the mobile app, a cluster randomized controlled trial design with three measurement points was conducted. Thirty-two Norwegian primary and secondary schools were randomly assigned to either an intervention group where the pupils (n = 259) got access to NettOpp during the study period, or to a waiting-list control group where the pupils (n = 327) got access to NettOpp after the study period. No significant findings were found in the intention-to-treat analyses, but the results from per-protocol analyses showed a decrease in hyperactivity problems among the adolescents that had used the app (F(4,1585) = 2.89, p =.021). Users of the app reported being more exposed to negative incidents online during the study period (F(2,1591) = 3.94, p =.020). The frequency of cyberbullying decreased during the study period, but among all study participants, including those who had not used the app. The findings provide valuable insight into whether mobile apps can function as preventive and supportive self-help resources in reducing the harmful effects of cyberbullying and negative online incidents on mental health outcomes among adolescents.
遭受网络欺凌和在线负面事件会对青少年的心理健康和幸福产生负面影响。NettOpp是一款移动应用程序，旨在减少网络欺凌和在线负面事件对心理健康结果的有害影响。为了评估该移动应用程序的效果，进行了一项具有三个测量点的整群随机对照试验设计。32所挪威中小学被随机分配到一个干预组，在研究期间，该组学生（n = 259）可以使用NettOpp；或者分配到一个等待名单对照组，该组学生（n = 327）在研究期结束后可以使用NettOpp。在意向性分析中未发现显著结果，但符合方案分析的结果显示，使用该应用程序的青少年多动问题有所减少（F(4,1585) = 2.89，p =.021）。该应用程序的用户报告称，在研究期间，他们在网上更多地遭遇负面事件（F(2,1591) = 3.94，p =.020）。在研究期间，网络欺凌的频率有所下降，但在所有研究参与者中，包括那些未使用该应用程序的人。这些发现为移动应用程序是否可以作为预防性和支持性自助资源，以减少网络欺凌和在线负面事件对青少年心理健康结果的有害影响提供了有价值的见解。
