Testing a Mediation Model of Dispositional Optimism, Mindful Self-Care, and Subjective Well-Being

Abstract

Research consistently demonstrates a positive association between dispositional optimism (DO) and subjective well-being (SWB). This study takes a step forward by exploring potential mechanisms underlying this relationship, with a specific focus on the mediating role of mindful self-care (MSC). We conducted a cross-sectional online survey involving 312 Singaporean adults. Participants completed questionnaires assessing their DO, MSC practices, and overall SWB. Our findings confirmed a significant link between DO and SWB, with individuals exhibiting higher optimism reporting greater well-being. Importantly, the relationship was mediated by MSC, suggesting that optimism motivates individuals to engage in MSC practices, which in turn, enhances SWB. Moreover, DO was linked to all SWB subcomponents, even after controlling for MSC as a mediator. Among the six MSC facets, self-compassion and purpose, supportive relationships, and mindful awareness emerged as significant mediators. This study adds to the growing body of evidence recognizing the positive role of DO and MSC in improving well-being outcomes. It highlights the potential of interventions aimed at cultivating optimism as a promising approach for enhancing mindful self-care practices and ultimately promoting well-being in adults.
