The incidence of self-injurious behavior (SIB) in adolescent psychiatric inpatients has been reported to be as high as 61%, yet few data exist on the characteristics and functional role of SIB in this population. Because of the repetitive nature of SIB and its potential to increase in severity, features of SIB and its specific reinforcing effects were examined.
Participants were 42 self-injuring adolescents admitted to a hospital over a 4 month period. Data sources consisted of self-report questionnaires and medical chart review.
Mean age was 15.7 +/- 1.5 years. Reported urges to self-injure were almost daily in 78.6% of the adolescents ( n= 33), with acts occurring more than once a week in 83.3% (n = 35). The two primary reasons endorsed for engaging in self-injury were "to cope with feelings of depression" (83.3%, n= 35) and "to release unbearable tension" (73.8%, n= 31). Of the sample, 97.6% ( n= 41) endorsed three or more addictive symptoms.
SIB in hospitalized adolescents serves primarily to regulate dysphoric affect and displays many addictive features. Those with clinically elevated levels of internalized anger appear at risk for more addictive features of this behavior.
据报道，青少年精神科住院患者中自伤行为（SIB）的发生率高达61%，但关于该人群中自伤行为的特征和功能作用的数据却很少。由于自伤行为具有重复性且严重程度可能增加，因此对自伤行为的特征及其特定的强化效应进行了研究。
研究对象为在4个月内入院的42名有自伤行为的青少年。数据来源包括自我报告问卷和病历审查。
平均年龄为15.7±1.5岁。78.6%（n = 33）的青少年表示几乎每天都有自伤冲动，83.3%（n = 35）的青少年自伤行为每周发生不止一次。参与自伤的两个主要原因是“应对抑郁情绪”（83.3%，n = 35）和“释放无法忍受的紧张情绪”（73.8%，n = 31）。在样本中，97.6%（n = 41）认可三种或更多成瘾症状。
住院青少年中的自伤行为主要用于调节烦躁情绪，并表现出许多成瘾特征。内化愤怒临床水平较高的青少年似乎有这种行为更多成瘾特征的风险。
