Abstract

This article describes the development and initial psychometric properties of the Milwaukee Inventory for the Dimensions of Adult Skin picking (MIDAS), a measure designed to assess "automatic" and "focused" skin picking. Data were collected from 92 participants who completed an anonymous internet-based survey. Results of an exploratory factor analysis revealed a two-factor solution. Factors 1 ("focused" picking scale) and 2 ("automatic" picking scale) each consisted of 6 items, and preliminary data demonstrated adequate internal consistency, good construct validity, and good discriminant validity. The MIDAS provides researchers with a reliable and valid assessment of "automatic" and "focused" skin picking.
