[Structural relationship between pathology of self-differentiation in Bowen's family therapy with subjective well being, mental health and hygiene of marital quality, "Fitting Bowen's Theory"]

Many theorists have attempted to illustrate family functions. Bowen developed the theory of the family system. This theory is fundamentally based on the concept of differentiation of self. This study was intended to examine the relationship between self-differentiation and subjective well-being, mental health and marital quality in the framework of Bowen's theory. In this descriptive-correlation study, 560 subjects were chosen randomly from the clients of counseling centers and house of cultures [Farhang Sara] in Isfahan city. Our research tools were consisted of Differentiation of Self Inventory-2 [DSI-2], General Health Questionnaire [GHQ], Satisfaction with Life Scale [SWLS], Positive and Negative Affect Scales [PANAS] and Revised Dyadic Adjustment Scale [RDAS]. First, construct validity of questionnaires were examined by confirmatory factor Analysis [CFA]. Then, structural model for conceptualization of the relationship between differentiation of self and other factors is presented and fitted by reviewing of preceding studies within framework of Bowen's theory. Result revealed that proportion and sufficiency of model fitting indices is indicator of suitable internal validity. The results of study confirmed construct validity of questionnaires and relationships between self-differentiation and subjective well being, mental health and marital quality" Fitting Bowen's theory"
