Abstract

Objective: To demonstrate the reliability and validity of the Assessment of Capacity for Everyday Decision-Making (ACED), an instrument to evaluate everyday decision-making.

Methods: The authors administered the ACED to 39 persons with very mild to moderate cognitive impairment and 13 cognitively intact caregivers.

Results: Intraclass correlation coefficients showed good reliability for the measures of understanding, appreciation and reasoning, and Cronbach's alpha coefficients were > or =0.84 for all three decision-making abilities. The ACED also had a moderate to strong correlation with the MacArthur Competency Assessment Tool for Treatment, a validated measure of decision-making capacity for medical treatment decisions, and measures of overall cognition. Associations with measures of executive function were mixed, with moderate correlations observed only with ACED understanding and reasoning performance.

Conclusion: The ACED is a reliable and valid measure to assess decision-making capacity. It may serve as an important addition to current methods used to assess everyday decision-making.
