Cognitive composites possess higher sensitivity relative to individual neuropsychological tests, might be less susceptible to floor and ceiling effects, and reduce statistical multiplicity.The Preclinical Alzheimer Cognitive Composite 5 (PACC5) is a validated global cognitive composite sensitive to detecting and tracking preclinical AD-related decline.Baseline demographic and clinical characteristics were obtained from participants. Following the first intervention session, participants’ perceptions of intervention credibility and expectations of deriving benefit were measured via the Credibility/Expectancy Questionnaire.
