Abstract
Objectives: Conscientiousness is associated with positive health behaviors and outcomes and has been shown to increase as individuals age. Both age and Conscientiousness affect pain, a highly prevalent correlate of aging. This study investigated the effect of Conscientiousness on the relationship between pain and pain interference and vice versa among older adults, who experience pain and functional limitations disproportionately compared with younger adults.
Methods: A total of 196 community-dwelling older adults (Mage = 73) provided pain and interference ratings semiannually for up to 10 years. Conscientiousness was assessed at the first visit and, on average, 7.6 years later. Multilevel models tested the effect of Conscientiousness on the relationship between pain and interference. Hierarchical regression modeled changes in Conscientiousness.
Results: Across all pain levels, higher Conscientiousness was associated with less pain interference (γ02 = -0.126, SE = 0.048, p < .01, 95% confidence intervals (95% CI) [-0.22, -0.03]). This effect was more pronounced at higher levels of pain and older age. Conscientiousness increased slightly over time, but older baseline age (b = -0.01, 95% CI [-0.03, -0.001], R2 = 0.02) and more mean pain interference over the study period (b = -0.17, 95% CI [-0.30, -0.03], R2 = 0.03) were associated with less increase in Conscientiousness at follow-up.
Discussion: Higher pain and older age are associated with more pain interference, and Conscientiousness provided the most protection for these same individuals-those with higher pain and older age. Conscientiousness facilitated reduced interference, which may feed forward into higher Conscientiousness, potentially shaping a cycle between personality and health that extends through older adulthood.
期刊介绍：
The Journal of Gerontology: Psychological Sciences publishes articles on development in adulthood and old age that advance the psychological science of aging processes and outcomes. Articles have clear implications for theoretical or methodological innovation in the psychology of aging or contribute significantly to the empirical understanding of psychological processes and aging. Areas of interest include, but are not limited to, attitudes, clinical applications, cognition, education, emotion, health, human factors, interpersonal relations, neuropsychology, perception, personality, physiological psychology, social psychology, and sensation.
