Jacobs S, et al. - In this study of 409 community-dwelling, healthy older adults (56.5% female), researchers investigated risk factors related to the individual-level change in perceived social support (PSS), with a particular focus on personality (specifically Neuroticism and Extraversion) and gender. Annual follow up was performed up to 5 years indicating personality as a significant predictor of PSS change, including personality quadrants and High Neuroticism alone. Significant gender differences in stratified models were observed, with High Neuroticism-Low Extraversion and High Neuroticism alone consistently linked to PSS decline in males, while Low Neuroticism-Low Extraversion was linked to PSS decline in females. These findings may assist in earlier recognition of individuals who are at risk for decreased social support, and determining its related impact on health.
