Objectives: The Informant BAYER Activities of Daily Living Scale (BAYER) is a validated in-person interview tool to access functional deficits attributable to cognition in individuals with cognitive impairment. Telephone administration is utilized but has not been validated. Methods: Informants of potential recruits for the SMART trial of mental vs. resistance training exercise were asked to verify their baseline functional independence by telephone and in person. Each informant completed both modes of administration within 2 weeks of first contact, in nonrandomized order. The same researcher conducted all interviews. Bland-Altman and regression analyses were performed to evaluate concordance between modes of administration. Results: Twenty potential recruits (60% men, mean age 68 years±8 yr with cognitive TICS score ranging from 17-29/33) and informant pairs were evaluated. Informants were spouses (80%), children (10%), or friends (10%). There was a strong relationship between the two modes of administration (r= 0.861; p
