Abstract :

Introduction: Self-differentiation as the core concept of Bowen’s family systems theory refers to individual’s ability of differentiating between affective and mind processes. In other words, achieving a degree of emotional independence so that one is able not be drawn in to the emotional pool of emotionally laden situations, and decides in an  autonomous and rational manner. Purpose: The present study aimed at investigating the factor structure and validation of Drake et al.(2015) ’s Self-Differentiation Inventory Short Form (SDI-SF)in Iran. Method: Using convenience sampling procedure, a national sample of 1503 people( 433 males and 1070 females) whose age range was 14 to 62 for males and 18 to 59 for females was selected among internet social networks users. Then the selected users answered the electronic version of DSI-SF. Results: Using principal components method and Varimax rotation, five factors were extracted. So the results of confirmatory factor analysis showed that the factor structure of the inventory had a good fitness to the gathered data. In addition to checking for the content validity of the inventory, the reliability index was calculated(α= 0.741), showing an acceptable internal consistency.  Discussion: the results of factor analysis confirmed the original factor structure of the inventory, the reliability indices were similar to the results of previous research. Therefore according to the results of the study SDI-SF is an reliable and valid measure for determining the level of self-differentiation in the Iranian population.
