A Randomised Controlled Trial Using Experience Sampling Method as a Way to Improve Depressive and Anxiety Symptoms in Women at Risk of Common Mental Disorder in Hong Kong

Women who are at-risk for common mental disorders and have completed the online screening for Jockey Club Mental Wellness Project for Women (JCWow) will be recruited. This study aims to test the effectiveness of ESM-derived personalized feedback in reducing symptoms of depression and anxiety using a randomised controlled trial. After given written consent, the participants will be required to undergo a 5 days baseline ESM data collection (week 0). Upon completion of baseline data collection, they will be randomly assigned to the intervention (ESM-F), active reference (ESM) or control (CON) group. The participants in the intervention group will participate in an ESM procedure (three days per week over a 6-week period) using through SMS system (week 1 - 6). This group will receive weekly standardised feedback on personalised patterns of positive affect. The active reference group will also participate in the same ESM procedure without a weekly feedback. The control group will not be required to undergo this 6-week data collection procedure. At week 7, all three groups will undergo another 5 days of post-intervention ESM data collection in order to examine the naturalistic and interventional changes on the depressive symptoms. From week 8 onwards, the participants will be contacted 5 times (week 8, 12, 16, 20 and 32) via telephone to follow-up their condition. After 32 weeks, both active reference and control group will receive the report.
