Abstract
Background
Addressing modifiable risk factors can potentially prevent 45% of cases of dementia. Here, we present the development of Brain-WISE, a low-intensity, group-based intervention to improve brain health in community settings. We conducted preliminary testing to refine intervention materials and procedures, assess acceptability and adherence, and evaluate preliminary effects.
Methods
143 community-dwelling adults aged 56-93 completed the non-randomized pilot trial. The 6-session intervention included psychoeducation, discussion/activities, and health screenings. Adherence was measured by attendance and acceptability was measured with questionnaires. Brain health knowledge and motivation to improve brain health were assessed before and after the program.
Results
Across 6 cohorts, attendance was 80% - 97% and 96% of participants agreed that the program was worthwhile. Knowledge (d = 0.83, P < .001) and motivation (d = 0.43, P < .001) increased significantly.
Conclusions
The Brain-WISE program displayed good adherence and acceptability and evidence of an effect on knowledge and motivation. Further testing is warranted.
