- Brief Summary
Objectives: This study aims to explore the feasibility, acceptance, and efficacy of online group-based dual-task training as an intervention for improving cognitive function among community-dwelling older adults.
Hypothesis to be tested: We hypothesize that after the intervention, there will be an improvement in the participants' cognitive function as compared with pre-intervention status and with the control group. Also, lower-limb muscle strength and psychosocial wellbeing will be improved after the intervention.
Design and subjects: This is a randomised controlled feasibility study. The target population is community-dwelling older adults with access to an online meeting platform. About 75 participants will be recruited and randomised to the intervention and attention control groups in a ratio of 2:1. Intervention group will receive 60 minutes of online group-based dual-task training twice a week for 12 weeks led by a trained facilitator. Cognitive training components include arithmetic operation, verbal fluency, and upper limb/finger movement. Physical training components are chair-based exercises. The training components will be selected using a co-design approach.
Instruments: Memory Inventory in Chinese (MIC), Digit Span Test, Victoria Stroop Test, Montreal Cognitive Assessment 5-Minutes (Hong Kong Version).
Main outcome measures: Subjective memory complaints as measured by MIC.

- Primary Outcome Measures
Name Time Method Change from baseline subjective memory complaints at 6 weeks Six weeks after baseline Measured by Memory Inventory in Chinese. The sum of score ranges from 0 to 108, higher score indicates more memory complaints.
Change from baseline subjective memory complaints at 12 weeks 12 weeks after baseline Measured by Memory Inventory in Chinese. The sum of score ranges from 0 to 108, higher score indicates more memory complaints.
Change from baseline subjective memory complaints at 18 weeks 18 weeks after baseline Measured by Memory Inventory in Chinese. The sum of score ranges from 0 to 108, higher score indicates more memory complaints.
- Secondary Outcome Measures
Name Time Method Change from baseline cognitive status at 6 weeks Six weeks after baseline Measured by the Montreal Cognitive Assessment 5-Minutes (Hong Kong Version) (HK-MoCA 5-Min) protocol. The total score ranges from 0 to 30; a higher score indicates better cognitive status.
Change from baseline cognitive status at 12 weeks 12 weeks after baseline Measured by the Montreal Cognitive Assessment 5-Minutes (Hong Kong Version) (HK-MoCA 5-Min) protocol. The total score ranges from 0 to 30; a higher score indicates better cognitive status.
Change from baseline working memory at 6 weeks Six weeks after baseline Measured by Digit Span Test. The longer the series, the better the condition.
Change from baseline happiness at 6 weeks Six weeks after baseline Measured by the Chinese version of the 4-item Subjective Happiness Scale. The score is the average of the four items, and ranges from 1 to 7; a higher score indicates a higher happiness level.
Change from baseline happiness at 12 weeks 12 weeks after baseline Measured by the Chinese version of the 4-item Subjective Happiness Scale. The score is the average of the four items, and ranges from 1 to 7; a higher score indicates a higher happiness level.
Change from baseline executive function at 18 weeks 18 weeks after baseline Measured by Chinese version of the Victoria Stroop Test, with more time and errors as worse condition.
Change from baseline social isolation/integration at 18 weeks 18 weeks after baseline Measured by the Chinese version of the 6-item Lubben Social Network Scale. The total score ranges from 0 to 30; a higher score indicates a better social network.
Change from baseline cognitive status at 18 weeks 18 weeks after baseline Measured by the Montreal Cognitive Assessment 5-Minutes (Hong Kong Version) (HK-MoCA 5-Min) protocol. The total score ranges from 0 to 30; a higher score indicates better cognitive status.

Change from baseline executive function at 12 weeks 12 weeks after baseline Measured by Chinese version of the Victoria Stroop Test, with more time and errors as worse condition.
Change from baseline lower-limb muscle strength at 6 weeks Six weeks after baseline Measured by the 5-times chair stand task. The longer the time participants use to finish the task, the poorer the performance.
Change from baseline lower-limb muscle strength at 12 weeks 12 weeks after baseline Measured by the 5-times chair stand task. The longer the time participants use to finish the task, the poorer the performance.
Change from baseline depressive symptoms at 12 weeks 12 weeks after baseline Measured by the Patient Health Questionnaire-9. The scale ranged from 0 to 27, higher score indicates higher level of depressive symptoms.
Change from baseline depressive symptoms at 18 weeks 18 weeks after baseline Measured by the Patient Health Questionnaire-9. The scale ranged from 0 to 27, higher score indicates higher level of depressive symptoms.
Change from baseline social isolation/integration at 12 weeks 12 weeks after baseline Measured by the Chinese version of the 6-item Lubben Social Network Scale. The total score ranges from 0 to 30; a higher score indicates a better social network.
Change from baseline instrumental activity of daily living at 12 weeks 12 weeks after baseline Measured by Lawton's eight selected tasks. A summary score ranges from 0 (low function, dependent) to 8 (high function, independent) for women and 0 through 5 for men to avoid potential gender bias.
