Clinical Trial Summary

The proposed trial aims to test the feasibility of ecological momentary intervention on stroke caregivers' psychological distress.


Clinical Trial Description

75% of stroke caregivers report severe caregiver burdens, with 60% of stroke caregivers reporting at least one depressive symptom in Hong Kong. However, caregivers can experience difficulties in accessing and fully utilising existing services due to the varying types of care needs and its intensities amongst stroke survivors.

Ecological momentary intervention (EMI) as an innovative and personalised intervention has shown great potential in supporting psychological well-being; yet, there are no studies on using EMI for the caregivers' psychological support. The proposed trial aims to reduce stroke caregivers' psychological distress by delivering EMI through instant messaging applications to provide personalised and real-time support led by healthcare professionals.

Stroke caregivers screened by Patient Health Questionnaire-9 (PHQ-9) with scores ranging from 5 to 19 will be recruited from multiple sites including community centres, rehabilitation centres and outpatient clinics in public hospitals in Hong Kong, and individually randomised into the intervention group (n=20) or control group (n=20). The intervention group will receive the personalised instant messages for 4 weeks. The control group will receive general health information and regular messages reminding them to participate in follow-up surveys. The primary outcome will be the score of PHQ-9 at 4 weeks. Secondary outcomes will include anxiety, perceived stress, and caregiver burden. ;
