Abstract

Objective The Excoriation (skin"picking disorder) dimensional scale (SPD"D) is a new measure of excoriation skin picking disorder (SPD). The 5"item scale was developed by the Diagnostic and Statistical Manual (Fifth Edition) obsessive-compulsive spectrum disorders sub"workgroup to assist in the dimensional assessment of SPD. Method The aim of the present study was to provide a psychometric evaluation of this new scale in a large community sample. 803 participants were recruited from online community noticeboards around Australia. Results The results indicated that the SPD"D demonstrated a unidimensional structure, high internal consistency (rs = .87, .86, and .92 across three samples), and good test-retest reliability (rs = .86). The SPD"D also demonstrated good convergent validity with the Skin"Picking Scale Revised (rs = .90) as well as divergent validity with the generalised anxiety disorder scale (rs = .40). Conclusions Overall, the SPD"D appears to be a brief and reliable measure of SPD symptomatology.
