Abstract
OBJECTIVES: In the present study, the relationship between family functioning, differentiation of self and trait anxiety was examined. In addition, differences in trait anxiety and differentiation of self according to sex were studied. It was also checked whether family functioning predicted the achieved degree of differentiation of self, and whether family functioning and differentiation of self predicted the level of trait anxiety. Finally, it was analyzed whether the level of differentiation of self mediated the relationship between family functioning and trait anxiety. METHODS: The study involved 185 Spanish participants, aged between 18 and 56 years and the scales used were the Family Adaptability and Cohesion Evaluation Scale-20Esp (FACES-20Esp), the Differentiation of Self Scale (EDS) and the State-Trait Anxiety Inventory (STAI). RESULTS: The results indicated that family functioning was related to differentiation of self and trait anxiety, and that differentiation of self was related to trait anxiety. In addition, according to sex, differences were found in the degree of differentiation of self and in the I Position, with a higher score for men, as well as in Emotional Reactivity and trait anxiety, with higher scores for women. It was also observed that family functioning predicted the level of differentiation of self, and that differentiation of self and family functioning predicted trait anxiety. Finally, it was found that the relationship between family functioning and trait anxiety was partially mediated by differentiation of self. CONCLUSIONS: There are relationships between family functioning, differentiation of self and trait anxiety, and there are differences in differentiation of self and trait anxiety based on sex. The relevance of the results and their implications for clinical practice are discussed.
