Excoriation is commonly known as skin picking disorder which is a mental health condition characterized by repetitive picking of one's skin which can lead to impairment and stress. Researchers sampled 10,000 adults aged 18-69 and completed a survey to establish the occurrence of skin picking disorder. 213 participants reported as having a current skin picking disorder, 55.4% were female. 318 participants reported lifetime skin picking disorder, (current or past) 54.1% were female. Those with current skin picking disorder were significantly more likely to be female than those who have never skin picked. Comorbidities were common with GAD (63.4%), depression (53.1%) and panic disorder (27.7%). This study concludes skin picking disorder is relatively common in the general population and has high rates of comorbidity.
