Study Overview
Brief Summary
This study will examine the effects of a smartphone-based lifestyle medicine (LM) for improving psychological well-being in Chinese population. Since a range of lifestyle factors are involved in the pathogenesis and progression of common mental disorders (e.g., depression and anxiety), modifying different lifestyle factors simultaneously may be effective to improve our psychological well-being. Chinese dietary recommendations will be integrated into the app to increase the acceptability towards mental health intervention. Through this study, we aim to promote evidence-based patient care and to improve help-seeking and access to evidence-based interventions for improving psychological well-being.
Detailed Description
This study will be a randomized controlled trial on the effects of a culturally adapted self-help smartphone-based lifestyle medicine for improving psychological well-being in Chinese population. Prior to all study procedures, eligible participants will be required to complete an online informed consent (with telephone support). Around 30 eligible participants will be randomly assigned to either smartphone-based lifestyle medicine (LM group) or the waitlist control group (WL group) in a ratio of 1:1.

Outcomes
Primary Outcomes
Change in the Depression Anxiety Stress Scales-21
Time Frame: Immediately post-treatment and 1-month post treatment
DASS-21 is a 21-items scale, comprises of three sub-scales which measures the negative emotional states of depression, anxiety, and stress, over the past week. The DASS is based on a dimensional rather than a categorical conception of psychological disorder, thus it has no direct implications for the allocation of patients to discrete diagnostic categories. However, recommended cutoff scores for conventional severity labels (normal, moderate, severe) are given in the DASS Manual.
Secondary Outcomes
- Change in the Health-Promoting Lifestyle Profile (HPLP II)(Baseline, immediately post-treatment and 1-month post treatment)
- Change in the Short Form (Six-Dimension) Health Survey (SF-6D)(Baseline, immediately post-treatment and 1-month post treatment)
- Change in The Insomnia Severity Index (ISI)(Baseline, immediately post-treatment and 1-month post treatment)
- Change in the Sheehan Disability Scale (SDS)(Baseline, immediately post-treatment and 1-month post treatment)
- Change in the Credibility-Expectancy Questionnaire (CEQ)(Baseline, immediately post-treatment and 1-month post treatment)
- Change in the Food Frequency Questionnaires (FFQs)(Baseline, immediately post-treatment and 1-month post treatment)
- Change in the International Physical Activities Questionnaire - Chinese version (IPAQ-C)(Baseline, immediately post-treatment and 1-month post treatment)
- Self-developed survey(Baseline)
