Abstract
The objective of this study was to investigate satisfaction with and feasibility of an online cognitive behavioral-based group intervention (OK Onco Online) for adolescent childhood cancer survivors (CCS). The intervention, carried out by pediatric psychologists, aimed to prevent psychosocial problems. High levels of satisfaction were reported by the psychologists (n = 6) and the CCS (n = 11, age 11–17). The dropout rate was very low. Some recommendations for optimizing the intervention were mentioned. In conclusion, the positive evaluations by the CCS and the psychologists indicate that the online chat intervention OK Onco Online is a promising innovative group intervention for adolescent CCS. Further research is needed to confirm feasibility and to establish efficacy.
