Predictors of Self-Reported Problems of Confusion among the Aged

Responses to questions on the 1984 Supplement on Aging to the National Health Interview Survey (NHIS) about the experience of personal confusion revealed that two-thirds of those interviewed reported never having an episode of confusion during the preceding year. Of those who reported episodes, fewer than one in five said they were happening with increased frequency. The many meanings of confusion found in the literature prompted a modest local study of what respondents understood by the term when asked the NHIS questions. Of those who admitted occasional confusion, almost two-thirds gave definitions that included memory loss or forgetfulness. Consequently, increased frequency of memory problems and difficulty in remembering were included with other variables in the analyses to identify significant predictors. They emerged the single best predictors of how often a respondent reported getting confused. Others were change in health status, number of functional limitations, educational attainment, and vision problems.
