Assessment of anxiety in older adults: a community-based survey and comparison with younger adults.

The reliability and validity of existing anxiety self-report scales in elderly adults has not been adequately established, and the phenomenology of anxiety in older adults is largely unknown. In the present study, three anxiety scales and measures of depression and somatization were used to compare symptoms between older (n = 84, mean age = 75.3) and younger (n = 48, mean age = 40.3) community-dwelling adults. Results showed that the anxiety scales demonstrated good internal consistency in both age groups, although the reliabilities of the Fear Questionnaire subscales ranged from poor to good. Convergent and divergent validity were found to be variable in the older group, but this may reflect differences in anxiety as it occurs in older persons rather than psychometric problems. Anxiety symptoms did not vary with age, and levels of anxiety also remained constant. However, gender differences were found only within the older age group, with women reporting more anxiety than men. Findings are discussed with respect to current conceptualizations of anxiety in older people, as well as implications for future research.
