About this trial
This clinical trial aims to evaluate whether a culturally adapted Snacktivity™ program can improve cognitive function and self-care abilities in patients with Chronic Obstructive Pulmonary Disease (COPD) in Hong Kong.
The main questions it aims to answer are:
1. Does the Snacktivity™ program improve the cognitive function of participants (including both global cognition and targeted subdomains)? 2. Does the program improve participants' self-care abilities?
The study consists of three sequential phases:
Phase 1 (Co-design workshops): Co-design workshops will be conducted with COPD patients, healthcare professionals (nurses, physical therapists, occupational therapists), and family caregivers to culturally adapt the Snacktivity™ program for Hong Kong COPD patients.
Phase 2 (Feasibility Pilot RCT): The adapted program will be tested in a small-scale pilot study to assess its feasibility and short-term clinical effects.
Phase 3 (Full-scale RCT): A full-scale randomised controlled trial will be conducted to evaluate the program's efficacy on the primary and secondary outcomes.
Participants in the intervention group will be asked to:
Participate in the culturally adapted Snacktivity™ program that integrates short, manageable "snacks" of physical activity into daily routines.
Wear an activity tracker to monitor physical activity levels. Complete questionnaires at multiple time points assessing cognitive function, self-care abilities, physical activity levels, self-efficacy, exercise capacity, quality of life, anxiety, and depression.
Researchers will compare the intervention group to an attention control group (receiving usual care with health education) to see if the Snacktivity™ program leads to greater improvements in these outcomes.
