Better and Healthier Together? The Mediation Effect of Positive Psychological Capital on the Relationship Between Perceived Social Support and Health-Related Quality of Life Among Older Adults.

This study aims to investigate the mediating effects of positive psychological capital (both as compound PsyCap and separate resources) in the relationship between social support and the two components of HRQoL: physical and mental health. We conducted the current cross-sectional study on a sample of 319 participants (114 male; 205 female) aged 65 to 90. The results indicated significant positive associations between social support, PsyCap, physical health and mental health. Compound PsyCap fully mediated the relationship between perceived social support and physical/mental health. Hope and optimism positively predicted physical health, while the same PsyCap resources, along with self-efficacy positively predicted mental health. The retirees that perceived increased social support presented higher levels of PsyCap, which in turn increased their physical and mental health. Our results highlighted some new explanatory mechanisms regarding the relationships between variables that affect health-related quality of life among older adults.
