The self in the obsessive compulsive related disorders: hoarding disorder, body dysmorphic disorder and trichotillomania
The most recent DSM saw a reclassification of obsessive compulsive disorder (OCD) as the prototypical disorder within a separate grouping that also includes hoarding disorder, body dysmorphic disorder (BDD) trichotillomania (TTM; hair pulling disorder) and skin picking disorder (American Psychiatric Association [APA] 2013) This followed a long standing debate over whether there is a spectrum of disorders sharing etiological underpinnings or phenomenology with OCD (Abramowitz, McKay, Taylor, 2011; Moulding, Nedeljkovic, Kyrios, 2011) While much research has highlighted the role of self in the symptomatology and treatment of OCD per se (see Ahern Kyrios, Chapter 12 in this volume; Aardema et al. 2013; Bhar Kyrios, 2007; Doron, Moulding, Kyrios, Nedeljkovic, 2008; Moulding, Aardema, O'Connor, 2014) less has considered the role of selfin the OCD spectrum. This chapter aims to address this gap specifically with reference to hoarding disorder, BDD, and TTM.
