The Revised Observed Tasks of Daily Living (OTDL-R), a performance-based test of everyday problem solving, was administered to a sample of community-dwelling older adults. The OTDL-R included nine tasks, representing medication use, telephone use, and financial management. The OTDL-R had a desirable range of difficulty and satisfactory internal consistency and showed a relatively invariant pattern of relations between measured tasks and the underlying latent dimensions they represent across White and non-White subsamples. The OTDL-R also correlated significantly with age, education, self-rated health, a paper-and-pencil measure of everyday problem solving, and measures of basic cognitive functioning. Thus, the OTDL-R is a reliable and valid objective measure of everyday problem solving that has great practical utility for assessing performance in diverse populations.
