The impact of effort-reward imbalance on loneliness of the elderly: the multiple mediation effect of social support and control belief in social domain

ABSTRACT

Objective: The empirical studies of loneliness have experienced unprecedented growth in the past decades. As such, there is now a growing body of research showing that loneliness is negatively related to physical and mental health. More recently, one of the most widely tested models of effort-reward imbalance (ERI) posits that the imbalance between high effort and low reward elicits strong negative emotions and sustained stress responses. Despite these developments, the mechanism between ERI and loneliness of the elderly remains unclear. In the current study, we explored how ERI influences loneliness via social support and control belief in social domain. Method: We selected a convenience sample aged 53–84 years old (N = 231) to complete a series of standard psychological assessments. Results: Multiple mediation analysis showed that (1) the positive effect of ERI on loneliness was partially mediated by social support (95% IC = −.001 to .078) and control belief in social domain (95% IC = .028 to .154), and (2) the chain mediating effect of both mediators was also significant (95% IC = .037 to .112). Discussion: The study suggests that ERI can influence loneliness through decreasing social support and subsequently reducing control belief in social domain.
