This study explores the serial mediating effect of perceived family support on psychological well-being. Based on social support theory, family system theory, and the Mental Health Continuum Short Form (MHC-SF), the research constructs a model of the pathway of perceived family support on psychological well-being. The results show that perceived family support has a significant positive relationship with emotional well-being, social well-being, and psychological well-being (P<0.001). Emotional well-being positively influences social well-being and psychological well-being (P<0.001). Social well-being positively affects psychological well-being (P<0.001). There were direct mediating effects of emotional well-being (13.45%), direct mediating effects of social well-being (32.82%) and a serial mediating effect (28.07%) between perceived family support and psychological well-being (P<0.001). Perceived family support refers to how an individual perceives the assistance received from other family members, such as parents. Previous studies have shown that perceived family support can provide emotional support, information support, and substantive support, and help people build self-confidence, self-esteem, and self-regulation ability. However, there is still a lack of comprehensive understanding of how perceived family support affects mental health and well-being. Therefore, the objective of this research is to investigate the pathway through which perceived family support influences psychological well-being and uncover the underlying mechanisms linking mental health and overall well-being. The study used the MHC-SF to measure mental health and well-being, and the multidimensional scale of perceived social support to assess perceived family support. The results showed that perceived family support had a significant positive relationship with emotional well-being, social well-being, and psychological well-being. Emotional well-being and social well-being played a mediating role in the relationship between perceived family support and psychological well-being. The study also found that emotional well-being had a significant positive impact on social well-being, and social well-being had a significant positive impact on psychological well-being. The study concludes that perceived family support plays a vital role in improving psychological well-being through emotional and social well-being. The findings may contribute valuable insights for future research in this field.This study explores the serial mediating effect of perceived family support on psychological well-being.
