Constructing A Model of Health Promotion and Active Aging for Community-Dwelling Older Adults

Study Overview
=================
Brief Summary
-----------------
Cognitive intervention for people with subjective cognitive complaints can be categorized into cognitive training, cognitive rehabilitation, psychoeducation, lifestyle intervention, etc. Literature have suggested multicomponent cognitive interventions can have better outcomes. However, studies to support this proposition are still limited. Few studies have also examined the influences of cognitive intervention on functional performance. This study was to examine the effectiveness of a multicomponent cognitive intervention for community-dwelling elderly with subjective cognitive complaints.

Design Details

Primary Purpose: Treatment
Allocation: Non-Randomized
Intervention Model: Parallel Assignment
Interventional Model Description: A quasi-experimental design with nonequivalent control was adopted in a senior center. Experimental variable was a 12 consecutive 90-minute weekly cognitive groups that included cognitive training and rehabilitation, with activity-based cognitive exercises and discussions with a focus on applications of cognitive strategies in daily lives. Participants were allocated into intervention group (cognitive intervention group) and control group (nutrition education group). The group assignment depended on what group they signed up for participate.
Masking: None (Open Label)
