The research is applicative and the research method was correlational through structural equations modeling. The statistical population of this study included married women referring to counseling centers in Tehran in 2024. Among the statistical population, 338 people were selected by available sampling method. The research tools included Marital Covert Aggression Questionnaire, Differentiation of Self Questionnaire (DSQ) and Perceived Stress Questionnaire. The results showed that the structural model of the research fits the collected data. The results also showed that the total path coefficient (sum of direct and indirect path coefficients) between differentiation and marital covert aggression is negative and significant. Also, the path coefficient between differentiation and perceived stress is negative and significant. In addition, the path coefficient between perceived stress and marital covert aggression was positive and significant. Finally, the indirect path between differentiation and marital covert aggression was negative and significant. This finding indicated the significant role of perceived stress in the relationship between differentiation and marital covert aggression in married women.
