Does psychological capital mediate the impact of dysfunctional sleep beliefs on well-being?

Abstract

Dysfunctional sleep beliefs are strongly involved in sleep difficulties, which in turn negatively predict psychological health and well-being. In contrast, psychological capital (PsyCap) is a positive cognitive resource, comprising four dimensions (hope, self-efficacy, resilience, and optimism), that positively predicts psychological well-being. Significant associations between sleep beliefs and well-being, and PsyCap and well-being are detailed; however, research on their interrelations (among sleep beliefs, well-being, and PsyCap) remains scarce. This cross-sectional study aimed to elucidate the relationships among the variables. The convenience sample consisted of 123 Australian working adults. Participants completed an online survey comprising four empirically established measures (Dysfunctional Beliefs and Attitudes about Sleep Scale, Psychological Well-being Scale, Psychological Capital Questionnaire, and a social desirability scale). Hypotheses were derived from Conservation of Resources (COR) theory, which underlines the importance of cognitive mechanisms that guide adaptive psychological responses. Results were consistent with hypotheses: dysfunctional sleep beliefs significantly and negatively predicted PsyCap, and PsyCap mediated the relationship between sleep beliefs and well-being. Findings suggested that PsyCap, which can be developed, may help buffer the adverse effects of sleep beliefs to benefit well-being. Replication of model coefficients in larger samples and future testing of PsyCap training within sleephygiene practices are recommended.

Effects of interpersonal sensitivity on depressive symptoms in postgraduate students during the COVID-19 pandemic: Psychological capital and sleep quality as mediators

“…Our findings also revealed the serial multiple mediating roles of PsyCap and sleep quality in the pathway from interpersonal sensitivity to depression in Chinese postgraduate students. Sleep quality was negatively affected by PsyCap in our study, which was consistent with previous research in different populations ( 42 , 43 ). The psychological capital of postgraduate students may be affected to varying degrees by interpersonal sensitivity, which may affect the quality of sleep through psychological capital, leading to depression.…”

“…In addition, PsyCap has been shown to be a robust predictor of sleep quality ( 42 ). PsyCap may also mediate the effects of dysfunctional sleep beliefs on wellbeing ( 43 ) and the pathway from organizational justice variability to employee sleep quality ( 44 ). Currently, there is little research on the sleep quality of postgraduate students during the lockdown.…”

Psychological Capital and Burnout in Teachers: The Mediating Role of Flourishing

“…PsyCap is therefore shaped by the interaction of the resources of efficacy, optimism, hope, and resilience, which implies that these four attributes work synergistically as a higher resource, such that their predictive ability would be significantly greater when taken together than when taken separately [ 15 ]. In this regard, various studies in occupational and academic environments have shown that PsyCap predicts levels of flourishing significantly better when it is considered as a global construct [ 16 , 17 , 18 , 19 , 20 ].…”

Psychological Capital and Alienation among patients with COVID-19 infection: The mediating role of Social Support

“…Through the investigation of 259 COVID-19 patients, we found that their psychological capital can directly predict social alienation. Psychological capital is a positive psychological state which can buffer the negative effects of negative emotions (Sabot & Hicks, 2020). The negative correlation between psychological capital and social alienation was veri ed by the correlation analysis in patients with COVID-19 infection (p < .01).…”
