The contribution of family structure and differentiation to identity development in females

We examined the relationship between Minuchin's structural family model, adolescent separation-individuation, and identity development. One hundred sixty-four female undergraduate students completed the Structural Family Interaction Scale Revised (SFIS-R), the Parental Relationship Inventory (PRI), and the Extended Objective Measure of Ego Identity Status (EOM-EIS) scale. Exploratory Factor Analysis of the SFIS-R and PRI scales indicated that two factors, Proximity-Differentiation and Generational Hierarchy-Differentiation, accounted for 90% of the variance. Canonical correlation analysis with the two factor scores and age included in the predictor variables, and the four measures of ego identity included in the dependent variables, yielded two significant roots. The results supported Minuchin's model.
