Nj. Keuthen et al., THE MASSACHUSETTS-GENERAL-HOSPITAL (MGH) HAIRPULLING SCALE .1. DEVELOPMENT AND FACTOR-ANALYSES, Psychotherapy and psychosomatics, 64(3-4), 1995, pp. 141-145
We developed the MGH Hairpulling Scale to provide a brief, self-report
instrument for assessing repetitive hairpulling. Seven individual ite
ms, rated for severity from 0 to 4, assess urges to pull, actual pulli
ng, perceived control, and associated distress. We administered the sc
ale to 119 consecutive patients with chronic hairpulling. Statistical
analyses indicate that the seven items form a homogenous scale for the
measurement of severity in this disorder.
