Does Everything Depend on an Individual’s Personality? The Potential Positive Impact of Pro-Environmental Behaviour on Individuals’ Subjective Well-Being

Abstract

In this study, we examine whether personality profiles moderate a recently proposed environmental behaviour–well-being model. The model is grounded in Self-Determination Theory, which suggests that pro-environmental behaviour may contribute to subjective well-being through the satisfaction of basic psychological needs. A total of 403 adolescents from four Lithuanian schools participated in this study. Participants were selected using a convenience sampling method, and the average participant age was 14.89 years (56.6% female). Structural equation modelling demonstrated acceptable model fit (CFI = 0.988, TLI = 0.986, NFI = 0.929, RMSEA = 0.043 [0.022–0.058], SRMR = 0.113, χ2 (353) = 416.92, p = 0.011) and indicated that personality profiles moderate several pathways within the environmental behaviour–well-being model. Additionally, the results showed that pro-environmental behaviour and connectedness to nature did not significantly predict subjective well-being across all personality profiles. The findings highlight the importance of considering personality differences when designing sustainability-related educational interventions aimed at promoting environmental citizenship and improving subjective well-being.
