Brief Summary

Building upon our previous groundwork including the development of the FAMILY MOVE app and the pilot study, we will further evaluate the effectiveness of a simple parent-child partner exercise programme delivered by our FAMILY MOVE app on children's health-related quality of life through a single blinded randomized placebo-controlled trial (RCT). This RCT will sample 286 low-income parent-child pairs recruited from low income families in the community. Study participants will be randomized after baseline assessment by an independent statistician using computer randomization tool with 1:1 allocation ratio to either the FAMILY MOVE app intervention group or the HK FitNuts app control group. After both groups have completed the intervention study and follow up measurements at 1 month, 6 months and 12 months after intervention, the control group will receive the same FAMILY MOVE app. Outcome assessments will be conducted by a trained interviewer blinded to the subject group allocation at baseline, 1 month, 6 months and 12 months after intervention.

Outcome Measures

Primary Outcomes (2)

• Change from Baseline Child Psychosocial Health at 1 month and 6 month post intervention

  Chinese Child Health Questionnaire - Parent Form - 50 (CHQ-PF50); including 12 domain scales (General Health, Physical Functioning, Role/Social Limitations - Emotional/Behavioral, Role/Social Limitations - Physical, Bodily Pain/Discomfort, Behavior, Mental Health, Self-Esteem, Parental Impact - Emotion, Parental Impact - Time, Family Activities, and Family Cohesion) and 2 summary scores (Physical Summary Score and Psychosocial Summary Score). Higher scores indicate better HRQoL.

  baseline, 1 month, and 6 month post intervention

• Change from Baseline Child Total Physical Activity Score (MET-minutes/week) at 1 month and 6 month post intervention

  International Physical Activity Questionnaire - Short Form - Chinese version (IPAQ-SF); including seven questions on the frequency and duration of time spent in physical activity in the past 7 days to calculate a score for each domain (walking, moderate-intensity activities and vigorous-intensity activities) and an overall grand total expressed in MET-minutes/week.

  baseline, 1 month, and 6 month post intervention

Secondary Outcomes (4)

• Change from Baseline Parental Mental and Physical Health at 1 month and 6 month post intervention

  baseline, 1 month, and 6 month post intervention

• Change from Baseline Child SDQ Total Difficulties Scores at 1 month and 6 month post intervention

  baseline, 1 month, and 6 month post intervention

• Change from Baseline Parent Total Physical Activity Score (MET-minutes/week) at 1 month and 6 month post intervention

  baseline, 1 month, and 6 month post intervention

• Change from Baseline Parental DASS scores on each subscale (Depression, Anxiety and Stress) at 1 month and 6 month post intervention

  baseline, 1 month, and 6 month post intervention

Interventions

Family Move app intervention BEHAVIORAL

All the recruited parent-child pairs will be randomized after baseline assessment by an independent statistician using computer randomization tool to either the FAMILY MOVE app intervention group or the HK FitNuts app control group with a 1:1 allocation ratio. Although both groups receive a stand-alone app, the apps have distinct design features: use of competition and point elements (FAMILY MOVE app) or use of traditional demonstration elements (HK FitNuts app). After both groups have completed the 8-week intervention study and follow up measurements at 1 month, 6 months and 12 months after intervention, the control group will receive the same FAMILY MOVE app. Outcome assessments will be conducted by a trained interviewer blinded to the subject group allocation.

Intervention group

"HK FitNuts" app intervention BEHAVIORAL

The parent-child pairs in the control group will be given a link to download the "HK FitNuts" app which was developed by Hong Kong Association of Sports Medicine and Sports Science, Department of Orthopaedics \& Traumatology of the Chinese University of Hong Kong and Hong Kong Dietitians Association to promote healthy lifestyle in Hong Kong. The app includes short video clips demonstrating basic individual exercise moves and provides other textual information related to PA. However, it does not have push notification function. In order to ensure that the intervention and control group will receive equal attention from our research team, we shall send a text about HK FitNuts and general exercise information to participants in the control group three times per week. Same as participants in the intervention group, the control group will also be asked to provide their weekly app usage and PA pattern by completing an online log at the end of each intervention week.
