A RCT Evaluating a Chatbot in Increasing Physical Activity Among Older Adults

Not yet recruiting
Clinical Trial NCT06641492 is an interventional study for Physical Inactivity is not yet recruiting. Enrollment is planned to begin on November 1, 2024 until the trial accrues 278 participants. Led by Chinese University of Hong Kong, this trial is expected to complete by December 31, 2025. The latest data from ClinicalTrials.gov was last updated on October 15, 2024.
Brief Summary
This study will compare the efficacy of a Chatbot-delivered stage of changes (SOC)-tailored online intervention (intervention group) versus a Chatbot-delivered non-SOC-tailored online intervention in increasing the prevalence of meeting WHO recommended physical activity level six months after completion of the intervention among inactive community-dwelling individuals aged ≥65 yeas. In the intervention group, the Chatbot will assess participants' physical activity level and SOC regarding PA and automatically deliver interventions tailor to their SOC every week for 12 weeks. In the control group, the Chatbot will not assess participants' SOC. It will assess participants' physical activity level and provides a standard intervention covering general information about physical activity for older adults, which is not tailoring to participants'SOC every week for 12 weeks. All participants will be followed up after completion of the interventions (T1) and six months after T1 (T2).

ExperimentalIntervention
The Chatbot will assess participants' physical activity level and stage of changes regarding physical activity and automatically deliver interventions tailor to their stage of changes every week for 12 weeks. The Chatbot will address questions related to physical activity raised by the participants.
Chatbot-delivered Interventions Tailored to One's Stage of Changes
The Chatbot will assess participants' physical activity level and stage of changes regarding physical activity and automatically deliver interventions tailor to their stage of changes every week for 12 weeks. The Chatbot will address questions related to physical activity raised by the participants.
Active ComparatorControl
The Chatbot will not assess participants' stage of changes. It will assess participants' physical activity level and provides a standard intervention covering general information about physical activity for older adults, which is not tailoring to participants' stage of changes every week for 12 weeks. The Chatbot will address questions related to physical activity raised by the participants.
Chatbot-delivered Standard Interventions
The Chatbot will not assess participants' stage of changes. It will assess participants' physical activity level and provides a standard intervention covering general information about physical activity for older adults, which is not tailoring to participants' stage of changes every week for 12 weeks. The Chatbot will address questions related to physical activity raised by the participants.
Primary Outcome Measures
Outcome MeasureMeasure DescriptionTime Frame
Meeting WHO recommended level of physical activity
Prevalence of meeting WHO recommended level of physical activity (at least 150 minutes moderate-intensity aerobic physical activity every week) at T1 (after completion of intervention) and T2 (6 months after T1). Physical activity will be measured by self-reported data and using an accelerometer.
