“…This systematic review concerns the diagnostic comorbidity between borderline personality disorder (BPD) and the somatic symptom and related disorders or somatoform disorders as defined by the Diagnostic and Statistical Manual of Mental Disorders (DSM) (American Psychiatric Association (APA) , 1980, 1994, 2013). Historically, these disorders have been conceptualized as fairly distinct; however, similarities in their clinical presentation-including shared risk factors (early trauma, gender), correlates (emotion dysregulation, self-harm), chronic course, and consequences (functional impairment, significant healthcare utilization)warrant closer consideration of their overlap (van Dijke, 2012;Dixon-Gordon, Whalen, Layden, & Chapman, 2015;van der Kolk et al, 1996;Quirk et al, 2016;Sansone, Wiederman, & McLean, 2008). Previous narrative reviews on this topic were published over 20 years ago, including the association of personality traits and disorders with somatoform disorders (Bass & Murphy, 1995;Kirmayer, Robbins, & Paris, 1994), and a review of published case studies that examined the comorbidity of personality disorders with factitious disorder (Goldstein, 1998).…”
