Effectiveness of a Guided, Web-based, Stepped-care-approach to Cognitive Behavioral Therapy for Insomnia in Cancer Survivors

The goal of this multicenter randomized clinical trial is to develop and evaluate a web-based stepped-care approach to Cognitive Behavioral Therapy for Insomnia (CBT-I), specifically tailored to adult cancer survivors experiencing insomnia. Participants will be randomly assigned to one of three study arms: stepped-care web-based CBT-I (eSTEPCBT-I), standardized web-based CBT-I (eSTANDCBT-I), or care as usual (CAU). The study aims to determine whether a stepped-care approach can improve access to effective insomnia treatment while maintaining clinical effectiveness and cost-effectiveness.
