About this trial
This project aims to compare the effectiveness of Wellnuts, an evidence-based, algorithm-driven self-health assessment mobile application, in empowering asymptomatic young-to-midlife adults in Hong Kong, promoting health awareness, and improving health-seeking behaviour and linkage-to-care, compared with conventional web-based health resources. Participants will be randomly allocated to the mobile health intervention group (Wellnuts app with self-health assessment and health information) and the conventional web-based resources control group (health information from Centre for Health Protection website). Hopefully, population health will be improved with the general health promotion impact from the app.

Treatments tested in this trial
Wellnuts app intervention
Other interventionThe app adopts an evidence-based and algorithm-driven self-health assessment approach. It is designed to help participants assess their health risks, increase health awareness and encourage appropriate health-seeking behaviour. The app provides self-health assessment related to common health conditions and modifiable behavioural risk factors. Participants assessed as "at-risk" are provided with relevant recommendations, including recommended tests and follow-up actions where appropriate.
Web-based health resources
Other interventionConventional web-based health resources are from the Centre for Health Protection website which was run by the Department of Health (https://www.chp.gov.hk/en/healthtopics/25/index.html). These resources provide general health information and links to relevant support groups.
Treatment groups
Trial outcomes
Primary outcomes
Proportion of participants who sought medical assistance
Secondary outcomes
Proportion of healthy lifestyle behaviours
Lifestyle behaviours will be collected using a self-administered questionnaire. Healthy lifestyle behaviours include no tobacco smoking, no alcohol drinking, frequent physical activity, and diverse food intake.
Proportion of participants who attended the follow-up tests after being assessed as "at risk" by the mobile app
Level of satisfaction with the project
Level of satisfaction with the project will be evaluated using a five-point Likert item (very disappointed, disappointed, neutral, satisfied, very satisfied).
Other outcomes
Level of patient empowerment
Level of patient empowerment will be estimated using the Patient Enablement Instrument (PEI). PEI is a 6-item scale developed to assess the empowerment of patients after a consultation with their primary care clinician.
