Information was collected on 95 people with mental retardation who had been identified seven years previously as showing severe self-injurious behavior. At follow up 71% of participants were still showing self-injurious behavior of a severity which presented a management problem for care staff. The occurrence of specific topographies of self-injury was extremely stable among the group showing persistent self-injury. Finally, self-injury status at follow-up was predicted with 76% accuracy by a logistic regression model containing three variables: site of injury (higher persistence being shown by people exhibiting head directed self-injury); reported (greater) stability of self-injury when first identified; and (younger) age.
收集了95名智力迟钝者的信息，这些人在七年前被认定有严重的自我伤害行为。随访时，71%的参与者仍表现出严重程度足以给护理人员带来管理难题的自我伤害行为。在持续表现出自我伤害行为的群体中，自我伤害的特定表现形式极其稳定。最后，通过一个包含三个变量的逻辑回归模型，对随访时的自我伤害状况进行预测，准确率达76%，这三个变量分别是：受伤部位（头部自我伤害者表现出更高的持续性）；首次被认定时自我伤害行为报告的（更大）稳定性；以及（更年轻的）年龄。
