Deconstructing Differentiation: Self Regulation, Interdependent Relating, and Well-Being in Adulthood

This study examined underlying similarities between the Personal Authority in the Family System Questionnaire (PAFS; Bray, Williamson, & Malone, 1984a) and the Differentiation of Self Inventory (DSI; Skowron & Friedlander, 1998). Generalized least-squares factor analysis yielded two related factors, Self Regulation and Interdependent Relating, accounting for 60% of the variance in the solution. Greater Self Regulation—comprised of DSI scales characterized by less emotional reactivity and the ability to take an I position in relationships—and Interdependent Relating—marked by greater personal authority, intergenerational intimacy and less intergenerational fusion on the PAFS and less emotional cutoff on the DSI—predicted well-being among both women and men. Implications for family therapy and suggestions for future research are discussed.
