A RCT Evaluating a Chatbot in Increasing Physical Activity Among Older Adults
Sponsor: Chinese University of Hong Kong
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).

Interventions
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.
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.
