Abstract

The purpose of this study was to examine the factor structure, validity and reliability of the Massachusetts General Hospital Hair pulling Scale. Participants (304 male and 331 female) selected and the instruments of this study administered on them. Convergent validity of Massachusetts General Hospital Hair pulling Scale with the Obsessive–Compulsive Inventory-Revised, Yale –Brown Obsessive Compulsive Scale modified For BDD, Health Anxiety Inventory—Short Form and Skin Picking Impact Survey respectively were r=0.20, r=0.47, r=0.17 and r=0.47. Confirmatory factor analyses revealed total factor, one assessing impairment and the other symptom severity. The Cronbach's alpha for the total factor was 0.82. It can be concluded that this instrument is a useful measure for assess Hair pulling disorder symptoms in clinical assessment.
