OBJECTIVE: To determine the prevalence and association between body dysmorphic disorder (BDD) and social anxiety (SA) in dermatologic outpatients who attended a private clinic in Lima, Peru. MATERIALS AND METHODS: A transversal analytic study was done from January to May 2018 in which the Body Dysmorphic Disorder Questionnaire was used to measure body dysmorphic disorder and the Liebowitz Scale for Social Anxiety was used to assess social anxiety. These were previously translated and validated to Spanish. RESULTS: Six hundred ninety participants were enrolled; the majority (61.1%) were females. The median age was 34 years and the vast majority (52.7%) did not have a partner at the moment that the questionnaire was taken. The prevalence of body dysmorphic disorder was 52% and social anxiety was 18.8%. An association between body dysmorphic disorder and social anxiety was found and also between age and social anxiety.
