Cog-Fun老龄化以参与为中心，促进老年人健康

Cog Fun Ageing is a group-based occupation-centered intervention aimed at promoting positive occupational experiences despite cognitive challenges in day to day life. The intervention includes 14 weekly 120-minute group sessions led by experienced occupational therapists. Sessions incorporate learning about the bio-psycho-social factors of SCD and strategies to manage and cope with occupational challenges resulting from SCD.

The Memory Impact Questionnaire (MIQ) will be used to assess the impact of perceived memory changes on daily life. The questionnaire was developed for use in both clinical and research settings to better understand the impact of memory changes on the day-to-day functioning of older adults and to monitor outcomes of support programs for this population. The questionnaire includes 51-item comprised of three subscales: Lifestyle Restrictions (19 items exploring social relationships, work, volunteer and leisure activities), Positive Coping (19 items exploring participation in cognitively engaging tasks and other positive responses to memory changes), and Negative Emotions (13 items exploring negative self-perceptions and perceived negative judgments from others). The total score, calculated by reverse-coding Positive Coping items and summing all items, reflects the overall burden of memory changes, with higher scores indicating a greater negative impact.

The Patient Health Questionnaire-4 (PHQ-4) is a brief, self-report screening tool designed to quickly assess symptoms of depression and anxiety in the general population. It includes four questions, with two focused on anxiety and two on depression. The PHQ-4 combines two well-established scales: the PHQ-2 (depression) and the GAD-2 (anxiety).

Participants respond to each question based on how often they have experienced certain symptoms over the past two weeks, using a 4-point Likert scale from 0 = Not at all to 3 = Nearly every day. The total score ranges from 0 to 12, with subscale scores ranging from 0 to 6 for both anxiety and depression. Scores are rated as: 0-2- Normal; 3-5 -Mild; 6-8- Moderate; 9-12- Severe.

Total score ≥3 for first 2 questions suggests anxiety. Total score ≥3 for last 2 questions suggests depression.

The CASP-12 (Control, Autonomy, Self-realization, and Pleasure) is a self-report questionnaire designed to measure the quality of life (QoL) in older adults, specifically targeting individuals aged 50 and over. The CASP-12 includes 12 items spread across four dimensions: control (the ability to influence one's environment), autonomy (freedom from external influence), self-realization (personal fulfillment), and pleasure (enjoyment in life).

Participants rate each item on a 4-point Likert scale, ranging from 1 (often) to 4 (never), with higher scores indicating a higher quality of life. The total score can range from 12 to 48, where higher scores suggest greater well-being and satisfaction in the participants' lives.

The Engagement in Meaningful Activities Survey (EMAS) is a 12-item self-report questionnaire used to assess how meaningful a person's daily activities are. The survey asks participants to rate statements like "The activities I do give me a sense of satisfaction"; or "The activities I do help me feel competent," using a 4-point scale where 1 means "rarely"; and 4 means "always". The total score ranges from 12 to 48, with higher scores indicating higher levels of engagement in meaningful activities.

This tool is used to measure changes in how participants perceive the value and meaning of their activities. The EMAS helps identify whether interventions improve participants' sense of purpose and satisfaction in their daily lives.
