Although structural family theory proposes that family boundaries play a significant role in marital relationships, limited empirical evidence supports this theoretical model. The present study tested structural family theory by examining the complex associations between intergenerational boundaries and adult children's marital satisfaction, as well as the indirect effect of family adaptability and cohesion. A nonclinical convenience sample of individuals (333 participants, 168 females) married for at least one year was recruited. Participants provided self-report data on demographic variables, family boundaries, family cohesion and adaptability, and marital satisfaction. The internal intrusion score (intrusion by families of origin on the nuclear family) of intergenerational family boundaries was negatively associated with marital satisfaction, while the external intrusion score (intrusion by the nuclear family on families of origin) was positively associated with marital satisfaction. The effect of intergenerational family boundaries on marital satisfaction was exerted indirectly through family cohesion and adaptability. There was a significant association between intergenerational family boundaries and adult children's marital satisfaction. This study contributes to the conceptual framework of structural family theory, enabling family therapy practitioners to better understand the pathways through which intergenerational family boundaries impact adult children's marital satisfaction. Highlights: The findings shed light on the critical role that intergenerational family boundaries in marital relationships. The internal intrusion of intergenerational family boundaries was negatively associated with marital satisfaction, while the external intrusion demonstrated a positive association. The findings suggested a significant indirect association between family boundaries and marital satisfaction through family cohesion and family adaptability. [ABSTRACT FROM AUTHOR]
