Brief summary
The goal of this clinical trial is to learn if the Cog-Fun Aging program helps older adults with Subjective Cognitive Decline (SCD) manage memory challenges and improve their daily lives. The main questions it aims to answer are: * Does the program help participants better understand their cognitive challenges in daily life? * Do participants report using more effective strategies to manage their memory difficulties? * Does the Cog-Fun Aging program reduce negative emotions and self-perceptions related to SCD? Researchers will compare participants who complete the Cog-Fun Aging program with those who do not to determine the program's effectiveness. Participants will: Take part in a 10-week program with weekly sessions. Learn about SCD and how it affects daily life. Practice and monitor strategies to manage memory difficulties.
Interventions
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.
OTHERCog-Fun Aging Crossover
In the initial phase of the study (between T0 and T1) this group will receive "usual care". Participants are users of regional services where activities for healthy older adults are available. This group will continue going to activities as normal during the initial phase and then participate in the Cog-Fun Aging intervention.

Intervention model description
Participants will be recruited from three centers. Each center will form a homogenous group for the Cog-Fun Aging intervention. One center will include both an intervention group and a control group with a crossover component. At this center, participants in the intervention group will begin the 10-week Cog-Fun Aging program after an initial baseline assessment (T0). The control group will also be assessed at T0 but will not receive the intervention during this initial phase. Both groups will undergo a second assessment (T1) after the intervention group completes the program to evaluate changes. Following T1, the control group will participate in the intervention and undergo a final assessment (T2) to evaluate the effects of the intervention in the crossover phase. This design allows for comparison between the intervention and control groups, as well as evaluation of outcomes after the crossover phase.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Memory Impact Questionnaire (MIQ) | After enrollment (before intervention) and 10 weeks later (after intervention) | 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) |
| Multifactorial Memory Questionnaire-Short Version (MMQ-9) | After enrollment (before intervention) and 10 weeks later (after intervention) | 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). |
| Self-Regulation Skills Interview (SRSI) - adpated for study | After enrollment (before intervention) and 10 weeks later (after intervention) | 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. |
| SCD Awareness of Cognitive Difficulties in Daily Life Interview (SCD Interview) | After enrollment (before intervention) and 10 weeks later (after intervention) | A made-for-study interview to assess participants' ability to describe detailed events in which they encountered cognitive challenges in everyday life and gauge their capacity to identify and articulate the thoughts and emotions that influenced their experiences, the contextual factors that supported or hindered cognitive functioning, the strategies they employed, and how they monitored those strategies' effectiveness in real-time during negative SCD-related daily experiences. Together, the SRSI and the SCD Interview) will provide a comprehensive understanding of participants' awareness of difficulties and strategy use, supporting the evaluation of intervention outcomes. |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Patient Health Questionnaire for Depression and Anxiety (PHQ-4) | After enrollment (before intervention) and 10 weeks later (after intervention) | 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. |
