The authors' purpose of this study is to investigate the antecedents of single mothers' subjective well-being. A questionnaire-based survey was conducted using a multi-stage random sampling technique. Data were analyzed using Partial Least Square Structural Equation Modeling. The main findings are: (1) religiosity and locus of control positively influenced subjective well-being, (2) locus of control negatively influenced financial strain, (3) financial strain negatively influenced subjective well-being, and (4) age moderated the relationship between financial strain and subjective well-being. Implications and future research suggestions are discussed.
