Although hope has been identified as a source of psychological strength, limited data exists on how locus-of-hope is related to well-being. Self-Determination Theory (SDT) is a promising framework for further investigation of the role of external agents -in addition to the role of personal resources- in goal-achievement. Hope theory addresses “how” people pursue goals whereas SDT focuses on “why” goals are pursued. Examining locus-of-hope dimensions can advance the understanding of well-being through the lens of need satisfaction. In Study 1, the longitudinal effects among internal locus-of-hope, external locus-of-hope (family, peers and spirituality) and need satisfaction were examined with university students. According to results, cross-lagged effects of internal locus-of-hope were consistently established on need satisfaction, indicating that there is a direction from internal locus-of-hope to need satisfaction. Moreover, peer and spiritual locus-of-hope positively predicted internal locus-of-hope, but family locus-of-hope did not. Based on cross-lagged panel analysis, a longitudinal model was developed to examine how the locus-of-hope dimensions and need satisfaction predicted life satisfaction. The findings indicated indirect effects of family and peers locus-of-hope dimensions on life satisfaction, serially mediated through internal locus-of-hope and need satisfaction. Building on Study 1, Study 2 examined a sample of individuals with type II diabetes and found a significant indirect effect of family locus-of-hope on life satisfaction through the serial mediation of internal locus-of-hope and need satisfaction. Peer and spiritual locus-of-hope did not yield statistically significant effects. These findings underscore the critical role of locus-of-hope and need satisfaction in fostering well-being across different samples.
