SPD is defined as a habitual picking of skin, which in turn harms skin tissue. Given the paucity of information on SPD symptoms, their prevalence, and risk factors in Saudi Arabia, the present study seeks to fill this gap by investigating these factors in a community sample from Jeddah.Methods: This descriptive cross-sectional study was conducted in the city of Jeddah. The Skin Picking Scale-Revised (SPS-R) scale was administered to a convenience sample of 520 respondents. A partial least squares path model (PLS-PM) for “impairment” and “symptoms severity” subscales was assessed by evaluating the validity of measurement and structural models.Results: Skin picking behavior was reported by 28.8% (n=150). A significant level of skin picking disorder symptoms was present in 1.2% (n=6). Skin picking visual effect, depressive symptoms, and being unmarried were the only positive independent predictors of the total SPS-R score.Conclusion: SPD symptoms are relatively common among the adult population in Jeddah, but those with threshold symptoms indicative of SPD are relatively few. Such behavior is particularly common in vulnerable groups such as those with depressive symptoms and the unmarried. More attention to this condition by clinicians will improve the quality of life of those affected, and reduce the emotional and physical health consequences of this often unrecognized condition.Keywords: skin picking disorder, dermatillomania, excoriation disorder, prevalence, risk factors, The Skin Picking Scale-Revised scale
