Couple differentiation and health-related quality of life.

The purpose of this study was to examine whether couple differentiation influenced mental and physical health-related quality of life in couple members. Data for this study were derived from a larger study at a couple a family therapy clinic. One hundred and thirty-three couples were included in a latent profile analysis, and seventy-two couples were included in analyses of mean differences. The latent profile analysis resulted in three distinct groups by level of couple differentiation: high, moderate, or low in differentiation of self. Analyses of variance indicated evidence that couple differentiation influenced health-related quality-of-life measures. Findings are discussed in the context of Bowen Family Systems Theory and the existing literature.
