What this trial studies

This mixed-methods randomized controlled trial will enroll 208 informal caregivers of cancer patients and randomly assign them to either a 6-week self-help CBT-I program delivered via a WeChat mini program with weekly nurse support sessions (up to 20 minutes) or to sleep hygiene education. Participants complete assessments at baseline, immediately post-intervention, and at 3-month follow-up, with the primary outcome being change in insomnia severity. The intervention pairs digital CBT-I content with brief nurse coaching to support adherence and address practical barriers. Qualitative components will explore user experience and acceptability among Chinese-speaking caregivers.

Who should consider this trial

Good fit: Adults (≥18) who live with and provide at least 4 hours of unpaid daily care to a cancer patient, have an Insomnia Severity Index score >7, can read and speak Chinese, and can use WeChat are ideal candidates.

Not a fit: People with other untreated sleep disorders, serious psychiatric illness (for example psychosis or recent suicidal behavior), current use of psychotropic medications, pregnancy, or those unable to use WeChat or attend the Shanghai site are unlikely to benefit or be eligible.

Why it matters

Potential benefit: If successful, caregivers could experience meaningful reductions in insomnia and improved daytime functioning through a scalable, nurse-supported mobile intervention.

How similar studies have performed: Digital CBT-I has demonstrated efficacy for improving insomnia in multiple populations, though nurse-supported WeChat-based delivery specifically for informal cancer caregivers is relatively novel.
