  • Description: Background: Telephone-based interviews can be used for screening and to obtain key study outcomes when participants in longitudinal studies die or cannot be seen in person, but must be validated among ethnically and educationally diverse people. Objective: To determine the accuracy of a telephone interview in classifying (1) demented from nondemented participants, (2) cognitively impaired participants from cognitively normal participants, and (3) participants with mild cognitive impairment (MCI) from those with normal cognition or (4) MCI from dementia among an ethnically and educationally diverse community-based sample. Method: The sample consisted of 377 (30.5% non-Hispanic white, 34.7% non-Hispanic black, and 33.7% Caribbean Hispanic) older adults. The validation standard was diagnosis of dementia and MCI based on in-person evaluation. The Telephone Interview for Cognitive Status (TICS) and the Dementia Questionnaire (DQ) were administered within the same assessment wave. Results: The sample included 256 people (67.9%) with normal cognition, 68 (18.0%) with MCI, and 53 (14.1%) with dementia. Validity of the TICS was comparable among non-Hispanic whites, non-Hispanic blacks, and Hispanics. Among non-Hispanic whites, the DQ had better discrimination of those with dementia from those without dementia and from those with MCI than among other racial/ethnic groups. Telephone measures discriminated best when used...
