Introduction: As a result of the increasing average human life expectancy and the related population growth in many countries, research on factors increasing seniors' quality of life is becoming particularly important. An event critical for seniors' functioning is retirement. A concept reflecting the dynamics of seniors' personality associated with the changes taking place in their life situation is psychological capital. This concept was identified as a factor that is constituted by four personality variables changing because of experiences: self-efficacy, optimism, psychological resilience, and hope of success. An interesting issue is the relationship between psychological capital and quality of life in seniors working after retirement.
Aim: The aim of this paper was to analyze the relationship between psychological capital (self-efficacy, dispositional optimism, psychological resilience) and quality of life in seniors working after retirement, as well as the mediating role of hope of success in this relationship.
Methods: A total of 304 seniors-103 women and 201 men-participated in the study. The mean age was 65.24. The Quality-of-Life Scale (CASP-19), the Polish adaptation of Life Orientation Test (LOT-R), the Generalized Self-Efficacy Scale (GSES), the Hope of Success Questionnaire (KNS), and polish adaptation of the Resilience Assessment Scale (SPP-25) were employed in the research. A mediation model was applied to explore the pathway from psychological capital via hope of success to quality of life.
Results: The tested components of psychological capital correlate positively with working senior citizens' quality of life. The mediating role of hope of success between psychological capital and quality of life was confirmed. The study presented three mechanisms in which hope of success strengthens the relationships between the components of psychological capital and working senior citizens' quality of life.
Conclusions: The mediating role of hope of success between the remaining components of psychological capital and quality of life confirms pattern posited in the COR theory, namely, that increasing one resource leads to the activation of others, which results in a spiral of personal resources being generated. One the one hand, people who have greater resources have a greater capacity for generating spirals of gains. One the other hand, individuals who lack personal resources are both more exposed to losing them and less capable of starting a spiral of gains in resources.
