Participants in the control arm will not receive the Cog-Fun Aging intervention during the initial phase (10 weeks). Instead, they will undergo baseline assessments (T0) alongside the intervention group. After the first group completes the 10-week program, the control arm participants will be assessed again (T1). They will then begin the 10-week Cog-Fun Aging intervention and complete a final assessment (T2) after the intervention to evaluate its effects.

Cog Fun Aging is a group-based intervention aimed at promoting positive occupational experiences despite cognitive challenges in day to day life. The intervention includes 10 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 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. In this study the new short form (27 items), not yet published, was used with permission by the authors of the MIQ. The questionnaire includes three subscales: Lifestyle Restrictions (social relationships, work, volunteer and leisure activities), Positive Coping (participation in cognitively engaging tasks and other positive responses to memory changes), and Negative Emotions (negative self-perceptions and perceived negative judgments from others). The total score reflects the overall burden of memory changes, with higher scores indicating with higher scores indicating a greater negative impact. The MIQ has psychometric support, including test-retest reliability (rs = .65-.91) and internal consistency (αs = .87-.93)

The short version is a 9 item questionnaire that assesses metamemory. It consists of three scales measuring satisfaction with one's memory (MMQ Satisfaction), self-perception of one's everyday memory abilities (MMQ-Ability), and use of practical memory strategies in day-to-day life (MMQ Strategy). Items are rated on a 5-point Likert scale. The MMQ-9 demonstrates strong psychometric properties, with Cronbach's alpha scores of 0.92 for Satisfaction, 0.86 for Ability, and 0.79 for Strategy, indicating high internal consistency, and intraclass correlation coefficients of 0.89, 0.84, and 0.78, respectively, showing good test-retest reliability. Convergent validity is supported by correlations with related measures (e.g., 0.74 for Satisfaction and 0.70 for Strategy), while discriminant validity is confirmed by negligible correlations with unrelated constructs (e.g., 0.08 for Satisfaction).

Evaluates an individual's ability to articulate self-regulation and metacognitive skills in relation to daily life challenges. Includes 6 items that address key domains: emergent awareness, anticipatory awareness, readiness to change, strategy knowledge, strategy use, and strategy effectiveness. In this study, 5 of the 6 items will be utilized, excluding the readiness-to-change domain. Responses are scored on a 10-point scale, and scores are summarized and averaged into two main indices: awareness of difficulties and strategic behavior. Lower scores on these indices indicate stronger abilities in self-monitoring, recognizing, and anticipating difficulties, as well as identifying and effectively applying strategies to manage challenges. The tool demonstrates excellent psychometric properties, with interrater reliability ranging from 0.81 to 0.92 and test-retest reliability between 0.69 and 0.91.

A 4 item questionnaire that assesses emotional health. The tool combines the PHQ-2 for depression and the GAD-2 for anxiety, featuring a 4-point scale for responses, with total scores ranging from 0 to 12. Higher scores indicate more severe symptoms. The PHQ-4 has strong psychometric support, including internal reliability, construct validity, and factorial validity and criterion validity.
