Study summary

The proposed trial aims to evaluate the effectiveness of internet-delivered cognitive behavioural therapy (iCBT) based ecological momentary intervention (EMI) for psychological well-being in stroke family caregivers.

Read the detailed description

Many stroke patients require long-term care in the community. In Hong Kong (HK), most stroke caregivers in the community are family members, and many require psychological support for caregiver stress. However, these caregivers have difficulties accessing existing centre-based services due to varying work and care responsibilities, and therefore require alternative support services to meet their unique needs and schedules. Evidence shows that internet-delivered cognitive behavioural therapy (iCBT) is effective in managing psychological distress including depressive symptoms, especially when guided by healthcare professionals. Ecological momentary intervention (EMI) is an innovative and cost-effective intervention 'framework' that utilises mobile messages to deliver personalised psychological interventions. The proposed trial aims to deliver iCBT-based EMI through instant messaging applications (e.g. WhatsApp) to provide personalised and real-time psychological support led by nurses. Screened stroke caregivers with Patient Health Questionnaire-9 (PHQ-9) scores ranging from 5 to 19 (mild to moderately severe depressive symptoms) will be recruited from community centres, rehabilitation centres and outpatient clinics in HK. They will then be individually randomised into the Intervention group (n=128) or Control group (n=128). The Intervention group will receive the iCBT-based EMI for 12 weeks, which includes instant messages sent at the times and frequencies of the participants' choosing, and chat-based psychological support led by nurses to enhance effects of iCBT through real-time counselling and practical advice. The control group will only receive instant messages on general mental health information and reminders to participate in follow-up surveys. The primary outcome is PHQ-9 scores at 24 weeks. Secondary outcomes will include anxiety, perceived stress, caregiver burden, caring experience, spiritual well-being and quality-of-daily-life. We will strictly follow the CONSORT-EHEALTH checklist. A post-trial qualitative study will be conducted to understand the participants' experience of and compliance with the EMI. The intervention will be highly applicable for all caregivers requiring psychological support and will be one step further in meeting the World Health Organization's recommendations in supporting caregivers in the context of global ageing populations.

What researchers measure

Primary outcomes

  1. Depressive symptoms (Patient Health Questionnaire-9 [PHQ-9])

    A 9-item scale with score ranging from 0 to 27, higher scores indicate higher severity of depressive symptom

    Time frame: 24-week

Secondary outcomes

  1. Anxiety symptoms (Generalized Anxiety Disorder-7 [GAD-7])

    A 7-item scale with score ranging from 0 to 21, higher scores indicate higher severity of anxiety symptoms

    Time frame: 24-week

  2. Stress level (Perceived Stress Scale [PSS-4])

    A 4-item scale with score ranging from 0 to 16, higher scores indicate higher severity of stress

    Time frame: 24-week

  3. Caregiver's burden (Zarit Burden Interview [ZBI-4])

    A 4-item scale with score ranging from 0 to 16, higher scores indicate higher severity of caregiving burden

    Time frame: 24-week

  4. Caring experience (Positive Aspects of Caregiving [PAC])

    An 11-item scale with score ranging from 0 to 44, higher scores indicate more positive appraisal of caregiving experience

    Time frame: 24-week

  5. Spiritual well-being (Sub-scale of Spirituality Scale for Chinese Elders [SSCE])

    An 8-item scale with score ranging from 0 to 32, higher scores indicate better spiritual well-being

    Time frame: 24-week

  6. Quality of life (EuroQol 5-dimension 5-level questionnaire [EQ-5D-5L])

    A 5-item scale with predicted values ranging from -.864 to 1, higher values indicate higher health-related quality of life

Timeline

Tracking since Sep 25, 2026
ElapsedEstimatedEstimated, not yet reachedSimilar studies: half by the dot; the band is the middle halfHalf of similar studies reached it by the dot; the band is the middle half, from a quarter to three quarters

Ran from Sep 2021 to primary completion in Jun 2023, 21 months.

Of 2,859 non-industry interventional studies with no phase under Stroke, half reached primary completion within 23 months of starting (the median), counting those still running; a quarter within 10 and three quarters within 45. This study's 21 months is close to that.

Counting every sponsor, half of 2,988 studies reached it within 23 months; a quarter within 10 and three quarters within 45.

What these dates mean
Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
No changes since tracking began. The registry record was last updated on Jul 11, 2024, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
