Objectives: To review the efficacy of a home-based four-session individualized face-to-face cognitive rehabilitation (MAXCOG) intervention for clients with mild cognitive impairment (MCI) or early dementia and their close supporters.

Design: Randomized controlled trial comparing the intervention group (MAXCOG) with treatment as usual (control).

Participants: A total of 55 client–supporter dyads were enrolled in the study and 40 completed; 25 client–supporter dyads completed MAXCOG and 15 completed treatment as usual. Both MAXCOG and control groups included more MCI cases than dementia (22 versus 3 and 12 versus 3, respectively).

Intervention: Four weekly individual sessions of MAXCOG consisting of personalized interventions to address individually relevant goals, supported by the provision of the MAXCOG information resource.

Measures: The primary outcomes were goal performance and satisfaction, assessed using the Canadian Occupational Performance Measure (COPM). Questionnaires assessing mood, illness adjustment, quality of life, and carer burden were also administered.

Results: The intervention group displayed significantly higher performance and satisfaction with primary goals on the COPM post-intervention than the control group, using a per-protocol analysis.

Conclusions: The MAXCOG intervention is effective in improving goal performance and satisfaction in clients with MCI and early dementia.
