A Computer-based Memory Strategy Training Program for Older Adults

Acceptability is measured using a structured questionnaire divided into five sections: (1) the therapist-led group sessions, (2) the self-administered individual sessions, and (3) the computer program interface and iPad usability, (4) the overall program design and structure and (5) overall satisfaction. Participants are invited to give quantitative ratings on four dimensions under each section: (a) perceived effectiveness (e.g., whether the program improved cognitive strategy use), (b) relevance (e.g., how applicable the activities were to daily life), (c) convenience (e.g., ease) and (d) clarity. Responses are collected using a 4-point Likert scale, ranging from 1 "Completely disagree" to 4 "Completely agree," with higher scores indicating greater acceptability.

Feasibility by measuring the intervention attendance rate

The CERAD-NAB provides a profile on cognitive function by assessing cognitive deficits and was validated in a Chinese version. This study will use all subtests, including Verbal Fluency (J1), Boston's Naming (J2), Mini-Mental State Examination (MMSE, J3), Word List Memory (J4), Constructional Praxis (J5), Word List Recall (J6), Word List Recognition (J7) and Recall of Constructional Praxis (J8). The total score ranges from 0 -115 with a higher score indicating better performance.

The Digit Span Test consists of Digit Span Forward (DSF) and Digit Span Backward (DSB), measures immediate verbal recall, attentional capacity and working memory. The score is the number of digits in the longest successfully recalled sequence. A higher score indicates a better performance.

The self-reported Lawton Instrumental Activities of Daily Living Scale-Chinese version (IADLS) assesses one's ability to independently perform eight domains of instrumental daily activities such as meal preparation, laundry work, and shopping. The scale consists of nine items, each rated on a 3-point or 4-point scale, with a total score ranging from 0 to 18 or higher. A higher score indicates a better performance

The Chinese version of the Disability Assessment for Dementia (DAD) is a survey, completed by a proxy/carer, that evaluates the level of independence in daily activities for a person who has dementia or cognitive impairment. The DAD is scored based on a "yes/no" system, where "yes" indicates the person performed the activity without help, and "no" indicates they did not. The number of "yes" responses is totalled, and then converted to a percentage score out of 100. Higher percentage scores indicate better functional ability.

The EQ-5D-5L HK measures health-related quality of life in five dimensions: mobility, self-care, usual activities, pain/discomfort, and anxiety/depression, using five rating levels (33). The 5-level health status is converted to a utility value, ranging from 0 (death) to 1 (full health). The EQ-5D-5L HK includes a Visual Analogue Scale where respondents rate their overall health on a scale of 0 to 100.
