This article describes the psychometric evaluation of the Modified Reminiscence Functions Scale (MRFS). The 39-item MRFS was validated on a sample of 271 racially diverse older adults. Psychometric analysis included content validity, item analysis, principal component analysis with varimax rotation, test-retest reliability, and internal consistency reliability using Cronbach's alpha. The model's structure supports a seven-factor, 39-item scale. Test-retest and Cronbach's alpha for the instrument were .82 and .94, respectively. The seven-factor scale: self-regard, death, bitterness, intimacy, teach-inform, boredom, and conversation accounted for 61% of variance. Evidence indicates the self-report Likert instrument is a reliable and valid measure of reminiscence functions. Cross-validation with other populations and further research is needed to identify other reminiscence dimensions-functions.
