A self-rating scale for evaluating memory in everyday life.

A memory self-rating scale is described that includes 21 ability-to-remember items, 24 items assessing frequency of occurrence of memory failures, and 4 global rating items assessing overall comparison to others, comparison to the best one's memory has ever been, speed of recall, and concern or worry over memory function. Factor analysis yielded 5 orthogonal Ability to Remember and 5 orthogonal Frequency of Occurrence factors. The factor structure was not affected by age or sex, and level of complaint on the factor scores was not strongly associated with age.
