Purpose: The current study aims to examine the mediator role of early maladaptive schemas in the relationship between family function and subjective well-being among students. Research Methods: This study is based on a relational survey model, and the participants consist of 521 university students. The demographic information form, the Family Assessment Device, the Young Schema Questionnaire-Short Form-3, the Satisfaction with Life Scale, and the Positive and Negative Affect Schedule were used to collect the data. The data were analysed using structural equation modelling. Findings: The results revealed that the hypothetical structural model is valid. After testing the hypothetical structural model's validity, the statistical significance of the associations between the latent variables in the model was assessed. Results showed that early maladaptive schemas have partial mediator roles in the relationship between family function and subjective well-being. Additionally, findings presented that family function is directly and significantly associated with subjective well-being. Implications for Research and Practice: The findings represented the importance of early maladaptive schemas in the relationship between family function and subjective well-being. Thus, college counsellors might consider the role of early childhood experiences and family functions on the individuals' well-being. Future studies may focus on exploring the relationships between early childhood experiences and well-being using various research methods.
