Influencing Factors of Social Anxiety Disorder and Body Dysmorphic Disorder in a Nonclinical Brazilian Population.

The aims of this study were twofold: (i) to investigate the prevalence of social anxiety disorder and body dysmorphic disorder in a nonclinical, Brazilian population and (ii) to examine the effects of selected factors such as sociodemographic characteristics (sex, age, marital status, workload, education, and income), body mass index, current diet, physical activity, and use of aesthetic treatment. A total of 428 adults (279 women and 149 men) aged 18 to 60 years ( M = 31.51, SD = 10.73) participated in the study. Social anxiety disorder was measured using a Brazilian version of the Social Phobia Inventory ( Osório, Crippa, & Loureiro, 2009 ). Body dysmorphic disorder by using a body dysmorphic symptoms scale validated for the Brazilian population ( Ramos & Yoshida, 2012 ). The main results showed that 28.7% of the sample reported symptoms of social anxiety disorder. Body dysmorphic disorder was more prevalent among women, individuals who had sought aesthetic treatment and individuals who were physically inactive. Moreover, lower levels of social anxiety disorder were observed in physically active individuals who had sought aesthetic treatment compared with physically inactive individuals who had sought aesthetic treatment. Social anxiety disorder was negatively correlated with age, daily workload, and income, while body dysmorphic disorder was positively associated with body mass index and negatively with income. These results show that social anxiety disorder and body dysmorphic disorder are differentially influenced by the selected factors investigated in this study.
