An Empirical Model of Body Image Disturbance Using Behavioral Principles found in Functional Analytic Psychotherapy and Acceptance and Commitment Therapy.

The literature examining body image disturbance and Body Dysmorphic Disorder (BDD) is fraught with competing theoretical constructions of the etiology and nosology of these problems. Recent studies on various forms of psychopathology suggest that intrapersonal processes, including experiential avoidance, and interpersonal processes such as difficulties identifying and expressing emotions with others, correlate with higher levels of psychopathology. The present study aimed to investigate the relationship of body image disturbance and diagnosable BDD to the contemporary behavioral variables of experiential avoidance and interpersonal expression of affect. A large sample of participants including those who are diagnosable with BDD were examined. Results indicate that both intrapersonal and interpersonal variables are significant predictors of both body image disturbance in a large population and of BDD as a subsample and that these variables may be important targets for treatment. This principle-based conceptualization has parsimony and potential utility for clinical interventions of these problems. Implications are discussed for the use of contemporary behavioral treatments such as Functional Analytic Psychotherapy and Acceptance and Commitment Therapy to address both body image disturbance and BDD.
