Official title
Dual-task Training to Prevent Cognitive Decline in Community-dwelling Older Adults: A Pilot Pragmatic Randomised Controlled Trial
Overview
Objectives: This study aims to explore the feasibility and acceptance of group-based dual-task training for prevention of cognitive decline in a pragmatic setting for community-dwelling older adults. The primary objective is to assess recruitment rate, attendance rate, retention rate and satisfaction rate of participants. Study design and participants: This is a pilot pragmatic RCT with waitlist control. First, a co-design approach will be adopted to develop the intervention with the older adults. Then, about six participating community centres will nominate staff or volunteer to receive the training in order to lead the intervention. Informed consent will be sought from the participants and baseline assessment will be conducted. The participants will be randomly allocated to the intervention and control groups in 1:1 ratio using block randomisation with varying block size. At the end of the study, one representative of each participating centre will be invited to provide qualitative feedback. Measurements: The primary outcomes are the feasibility outcomes, namely the recruitment rate, attendance rate, the retention rate, and satisfaction rate of participants. Secondary outcomes include completion rate of the interventionist, time to recruit target sample size, factors influencing older adults' decision to participate and staff of the community centre to organise the activity, subjective memory complaints, working memory, executive function, and cognitive status of participants. A structured questionnaire will be used to collect quantitative outcomes related to effects and satisfaction. Qualitative feedback from representatives of the elderly community centres will be collected according to a semi-structured interview guide. Expected results: The intervention is feasible and highly accepted by the participants and staff of the community centres. Potential effect-related outcomes are to be demonstrated.
Interventions
- Other Dual-task training
Participants will receive a one-hour face-to-face group-based dual-task training session twice a week for 6 weeks. Training included cognitive components and physical components to be conducted simultaneously.
Primary outcome measures
- Recruitment rate [Time frame: After baseline, before randomization]
- Attendance rate [Time frame: 6 weeks after baseline for intervention group, 12 weeks after baseline for waitlist control group.]
- Retention rate [Time frame: 6 weeks after baseline for intervention group, 12 weeks after baseline for waitlist control group.]
- Satisfaction rate [Time frame: 6 weeks after baseline for intervention group, 12 weeks after baseline for waitlist control group.]
Secondary outcome measures (12)
- Completion rate of the interventionist [Time frame: End of study, up to 2 years]
- Time to recruit target sample size [Time frame: Before baseline]
- Factors influencing older adults' decision to participate and staff of the community centre to organise the activity [Time frame: At the end of recruitment briefing, before baseline]
- Change from baseline subjective memory complaints at 6 weeks [Time frame: 6 weeks after baseline]
