Towards the DSM-6: The intersection of OCD and psychosis. Expert perspectives on insight in the diagnosis of OCD.

In 1994, the DSM-IV added the specifier "with poor insight" to the diagnostic criteria of obsessive-compulsive disorder (OCD). The DSM-5 went one step further and now allows clinicians to diagnose OCD "with absent insight/delusional beliefs," thereby blurring the long-standing distinction between OCD and psychosis. The present study surveyed OCD experts as to their opinions on the insight specifier and the future classification of OCD.

[Body-Focused Repetitive Behavior Disorders: Classification, Diagnosis and Treatment].

Body-focused repetitive behaviors (BFRBs) such as trichotillomania and skin picking are disorders at the interface of psychiatry/psychology, dermatology and dentistry. The disorders can be both either a consequence or a cause of severe somatic disorders. If BFRBs remain undetected and untreated, they tend to become chronic with at times serious somatic complications.

Quo vadis DSM-6? An expert survey on the classification, diagnosis, and differential diagnosis of body-focused repetitive behaviors.

Background: Many conditions we now call body-focused repetitive behaviors (BFRBs) have been subject to research for several decades, most notably trichotillomania and skin picking. However, the American Psychiatric Association did not combine these conditions into a single category, body-focused repetitive behavior disorders (BFRBDs), until the fifth edition of the DSM (2013). Several aspects of the disorder remain uncertain and controversial.

Prevalence of body-focused repetitive behaviors in a diverse population sample - rates across age, gender, race and education.

Background: Prevalence estimates for body-focused repetitive behaviors (BFRBs) such as trichotillomania differ greatly across studies owing to several confounding factors (e.g. different criteria).
