Effects of Psychological Intervention Based on Digital Health Technology on Psychological Outcomes in Cancer Survivors: Systematic Review and Meta‐Analysis

DHT-based psychological interventions might be effective for improving anxiety, depression, sleep disturbances, fatigue, and quality of life in cancer survivors. We cannot draw definitive conclusions due to intervention and study design heterogeneity. Further rigorous trials are crucial to identify optimal interventions for different types of cancers, determine suitable durations, specify types of DHT-based psychological interventions and validate intervention therapies.
