强迫性精神障碍成年患者的皮肤抓挠和拔毛发癖
The objective of this study was to compare patients with obsessive-compulsive disorder (OCD) associated with pathologic skin picking (PSP) and/or trichotillomania, and patients with OCD without such comorbidities, for demographic and clinical characteristics. We assessed 901 individuals with a primary diagnosis of OCD, using the Structured Clinical Interview for Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition (DSM-IV) Axis I disorders. Diagnoses of PSP and trichotillomania were made in 16.3% and 4.9% of the sample, respectively. After the logistic regression analysis, the following factors retained an association with OCD-PSP/trichotillomania: younger (odds ratio [OR]=0.979; P=.047), younger at the onset of compulsive symptoms (OR=0.941; P=.007), woman (OR=2.538; P<.001), with a higher level of education (OR=1.055; P=.025), and with comorbid body dysmorphic disorder (OR=2.363; P=.004). These findings support the idea that OCD accompanied by PSP/trichotillomania characterizes a specific subgroup.
