Sex: ALL
Minimum age (years): 65
Standard ages: OLDER_ADULT
Accepts healthy volunteers: yes
Allocation: NA
Intervention model: SINGLE_GROUP
Primary purpose: PREVENTION

Brief summary: This intervention is designed to promote enhanced use of compensation strategies including calendar and task list use, and organization systems, as well as increased engagement with brain health activities including physical exercise, cognitive activities, and stress reduction.

Detailed description: The purpose of this study is to test the feasibility and efficacy of a 10-week multi-dimensional intervention for older adults with subjective cognitive concerns (SCC). The goal of this intervention is to enhance compensation skills related to everyday executive and everyday memory functions through training in the systematic use of a calendar system, goal setting and task list system, and organizational strategies within the context of the individual's daily life. This multidimensional intervention program also targets engagement in healthy lifestyle activities (physical exercise, intellectual stimulation, positive emotional functioning) to further promote brain health and functional resilience. Importantly, both treatment components work synergistically as the use of compensation strategies assists in building healthy activities into daily routines (e.g., scheduling exercise into one's calendar and putting it on a task list).

Eligibility criteria: Inclusion Criteria:

* A positive complaint in response to two questions ('Do you feel like your memory or other aspects of thinking are becoming worse?'; 'Does this worry you?')
* normal cognitive performance corrected for age and education on a global measure of cognitive functioning
* independent in all activities of daily living.
* English speaking;
* Available informant to complete surveys;
* Ambulatory

Exclusion Criteria:

* Known neurological condition;
* Severe psychiatric illness (e.g., current depression).
