Abstract: The aim of this research was to investigate the relationship between worries and psychological well-being, and self-rated health in older men. A cross-sectional survey method was used to investigate the research aim. A group of men aged 65 years and over (n = 217), who lived in a small New Zealand city, participated in this study. Results from this research revealed that worries about physical abilities and health were significantly related to a decrease in psychological well-being and self-rated health. Gerontological nurses are challenged to be cognisant of older men's concerns about their health and physical ability.
