Dream2Heal: An Adaptive Stepped-care Intervention for Chinese Cancer Survivors With Mild-to-moderate Insomnia

The primary objective of this feasibility study is to assess the feasibility and acceptability, and potential clinical significance of an adaptive stepped-care intervention for improving sleep quality among Chinese cancer patients with mild-to-moderate sleep disturbance, using a sequential multiple assessment randomized controlled trial (SMART) design. First, the investigators will test the effect of a low intensity web-based cognitive behavioural therapy for insomnia (CBT-I) intervention (iDream2Heal; iD2H), in comparison to a low intensity web-based exercise intervention (Easy Exercise; eEX). Secondly, this study aims to explore if a stepped-up face to face, therapist led CBT-I intervention (D2H) is more effective for patients who continue to have sleep disturbance, in comparison to an augmented intervention, in which is a combined, web-based intervention that covers the content of both iD2H and eEX interventions.
