This article reports result of two studies aimed at evaluating and comparing two short HFMPS versions provided by literature in Italian samples. In Study 1, two previously proposed short forms-Cox and colleagues' and Hewitt and colleagues'-were compared in terms of factor structure and concurrent validity in a community sample of 324 participants. In Study 2, validity and reliability of the two short scales in 102 university students and 58 patients with a primary diagnosis of Obsessive-Compulsive Disorder were examined. Results revealed mixed findings concerning which of the two short form should be preferred.
