Using data from the 1984 Supplement on Aging to the National Health Interview Survey, the associations among five health perceptions and two indices of functional health status were investigated within each of three age groups (55-64, 65-79, 80+). Greater functional impairment was associated with less favorable health perceptions in all three age groups. However, the strength of association was not consistent for the five indices, leaving room for conflicting assessments of one's health. Efficacy at taking care of health and perceived control over health showed lower strengths of association with functional impairment, raising the possibility that the resilience of some perceptions may be studied in greater detail. Results for persons aged 80 and older were similar in some ways to those for persons aged 55-64; however, there was some evidence of stronger negative association with increasing functional limitation among persons aged 55-64, suggesting a possibly stronger impact of health problems in this group. Future research might usefully examine intraindividual consistency of health perceptions and behavior, in addition to looking for normative interindividual trends.
