This study examined the associations among family cohesion (i.e., the extent to which family members are concerned and committed to the family), self-concept clarity (i.e., having a clear, confident and coherent sense of one’s own identity), hope (as a general disposition to engage in conscious efforts to obtain goals), and subjective well-being (containing emotional and cognitive well-being). 2792 adolescents and early adults with an age range of 11–24 years ( M age  = 16.45, SD  = 2.62, 43.2% boys) in China completed the Family Environment Scale, the Self-Concept Clarity Scale, the Children’s Hope Scale, the Satisfaction with Life Scale, and the Positive and Negative Affect Scale . Two serial mediation models revealed that self-concept clarity and hope independently mediated the effect of family cohesion on subjective well-being. More importantly, family cohesion could influence subjective well-being through the chain mediating effect of “self-concept clarity–hope”. These findings contribute to a deeper understanding of the links between these factors and suggest that high level of family cohesion may promote subjective well-being through the high level of self-concept clarity and hope.
