De klinische studie NCT06641492 is een interventioneel studie bij Lichamelijke inactiviteit met de status nog niet rekruterend. De inclusie van 278 deelnemers start op 1 november 2024. De studie wordt geleid door Chinese University of Hong Kong en de voltooiing is gepland op 31 december 2025. Laatste update op ClinicalTrials.gov: 15 oktober 2024.
Beknopte samenvatting
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).

ExperimenteelIntervention
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.
Actieve 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.
Primaire uitkomst
