Excoriation Disorder
Excoriation disorder, which is characterized by recurrent and impairing skin picking, has been included as a distinct diagnosis in the most recent version of the American Psychiatric Association’s Diagnostic and Statistical Manual of Mental Disorders (DSM-5). The move to include excoriation disorder as a separate diagnosis in the DSM-5 was largely due to increasing awareness of its prevalence and the potential for significant impairment and distress. This chapter discusses the nature, clinical presentation, and potential etiological determinants of excoriation disorder. In addition to the nature of symptoms, contemporary approaches to assessment and treatment, including behavioral and pharmacological, are highlighted. The chapter concludes with a discussion of future directions for research.
