Abstract
This study investigated individual differences in older adults' everyday problem-solving performance using 3 instruments. Past research, typically using only single measures, has yielded a multitude of findings regarding age effects in everyday problem solving. The present sample consisted of 111 older adults (44 men, 67 women) who ranged in age from 68 to 94 years. Confirmatory factor analyses revealed that, within each of the 3 instruments, subscales representing particular content domains could be reliably identified. There was, however, little relation between the different instruments, and the measures also differed in their relation with chronological age. These results support the view that everyday problem-solving competence is a multidimensional construct, of which previous investigations may only have studied particular dimensions.
