Psychiatric Comorbidity and Hoarding Symptoms in African Americans With Obsessive-Compulsive Disorder

This study investigated comorbidity and hoarding symptoms in a sample of African American adults with obsessive-compulsive disorder (N = 75). For lifetime disorders, 87.9% of participants had at least one other comorbid condition. The most prevalent comorbidities were mood disorders (67.1%), anxiety disorders (51.4%), and substance abuse disorders (38.0%). There was low comorbidity with eating disorders, as only 4.1% had binge-eating disorder and none met criteria for anorexia or bulimia nervosa. In terms of gender differences, females were more likely to have posttraumatic stress disorder and males were more likely to have a comorbid alcohol use disorder. Over half of the participants had hoarding compulsions (56.0%) as indicated by the Yale-Brown Obsessive-Compulsive Scale. Individuals with hoarding compulsions were more likely to have comorbid anxiety-related disorders than those without, and experienced greater indecisiveness, pathological slowness, and doubting; they also had less education and earning power than those without these behaviors. African Americans with obsessive-compulsive disorder tend to have high rates of comorbid disorders, with patterns that resemble findings in non-Hispanic White populations.
