Methods: Forty three subjects with a clinical diagnosis of OCD according to the Diagnostic and Statistical Manual of Mental Disorders (DSM-5) 42 subjects with a clinical diagnosis of social anxiety disorder (SAD), and 60 individuals without current or lifetime mental disorders (HC) were recruited from the Psychiatric Clinic of the University of Pisa. The goal of the current study is to ascertain the psychometric characteristics of the Obsessive–Compulsive Spectrum–Short Version (OBS-SV), a novel questionnaire designed to measure the complete range of obsessive–compulsive symptoms, from severe full blown to subthreshold ones. In particular, the conceptualization of an obsessive–compulsive spectrum appears to be in line with the very first descriptions of Obsessive–Compulsive Disorder and has been partially acknowledged by the inclusion of the “OCD-spectrum related syndromes and disorders” section in the DSM-5.
