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.
