Personality characteristics such as neuroticism, mastery, and self-efficacy explained an additional 4% to >30% of the variance in health-related quality of life beyond medical morbidity and age.
Observational (n=5,279)
Do personality characteristics influence health-related quality of life in older persons with chronic medical morbidity?
Personality traits such as neuroticism, mastery, and self-efficacy significantly influence reported health-related quality of life in older adults, independent of chronic medical morbidity.
Effect estimate: 4% to >30% variance explained
This article examines the main and moderating effects of 3 personality characteristics on the association between chronic medical morbidity and health-related quality of life (HRQL) in a large (N = 5,279) community-based older sample. Reasonably high unique contributions of neuroticism, mastery, and self-efficacy to HRQL were found. The additional amounts of variance explained beyond and above medical morbidity and age vary from about 4% (bodily pain) to above 30% (mental health). Little empirical evidence was found for the moderating effects of personality. In conclusion, personality characteristics such as neuroticism, mastery, and self-efficacy influence the reported levels of HRQL. The extent to which this is due to an influence of personality on true versus perceived levels of HRQL is unclear.
Kempen et al. (1997) conducted an observational in Chronic medical morbidity (n=5,279). Personality characteristics (neuroticism, mastery, self-efficacy) was evaluated on Health-related quality of life (HRQL) (4% to >30% variance explained). Personality characteristics such as neuroticism, mastery, and self-efficacy explained an additional 4% to >30% of the variance in health-related quality of life beyond medical morbidity and age.
