Cancer and treatment in adolescents cause psychological distress. Adolescents need to manage stressors and apply adaptive coping. This study aims to identify the effect of online peer support on psychological distress and coping in adolescents with cancer. The research design was a quasi-experimental pre-post test with a control group using a consecutive sampling. A sample of 60 adolescents was divided into the intervention group (n = 30) and the control group (n = 30). Online peer support was given to the intervention group, while the control group received educational videos. The analysis results using independent t-test showed that there were significant differences in scores of psychological distress as well as scores of planful problem solving, confrontation, seeking social support, accepting responsibility, and positive appraisal coping after online peer support intervention between two groups (p<0,05). The conclusion of this study is that there is an effect of online peer support on reducing psychological distress and increasing the use of adaptive coping in adolescents with cancer. Online peer support with appropriate methods needs to be given to adolescent patients with cancer as a collaborative intervention to reduce psychological distress and improve adaptive coping skills.
