title: Prevalence of self-injury in institutionalised retarded children.
abstract: Twenty-three percent of the inpatient population of a psychopaedic hospital in New Zealand were found to have engaged in self-injury during a six month observation period. Of the 50 male and 34 female patients studied, 62 exhibited single self-injury, and 22 multiple self-injury. Self-injury consisted of head banging, face slapping, skin picking, hair pulling, self-biting, regurgitation/vomiting, and excessive painful masturbation. Twenty-five percent of these patients indulged in forms of self-injury which was potentially seriously harmful to themselves if not immediately treated. The overall percentage of such patients in this hospital was found to be much higher than that reported elsewhere.
