To evaluate the relations between suicidal behavior in children and ego functions including impulse control, reality testing, and ego mechanisms of defense.
One hundred thirty-three children were assessed initially and at a 6- to 8-year follow-up for levels of reality testing and impulse control and frequency of use of several ego mechanisms of defense. Associations between suicidal ideation and suicide attempts at the initial assessment and at follow-up were analyzed with regard to ego functions.
Specific ego functions, such as impulsivity, poor reality testing, and ego mechanisms of defense such as projection, regression, compensation, and reaction formation were positively associated with suicide attempts. Repression was a protective factor to prevent suicide attempts in the follow-up period.
The results suggest that ego functions are related to behavior of consequence and are useful in the identification of children at risk for suicidal behavior.
评估儿童自杀行为与自我功能（包括冲动控制、现实检验和自我防御机制）之间的关系。
对133名儿童进行了初始评估，并在6至8年的随访中评估了他们的现实检验水平、冲动控制能力以及几种自我防御机制的使用频率。分析了初始评估和随访时自杀意念与自杀未遂之间关于自我功能的关联。
特定的自我功能，如冲动性、现实检验能力差，以及投射、退行、补偿和反向形成等自我防御机制与自杀未遂呈正相关。在随访期间，压抑是预防自杀未遂的保护因素。
结果表明，自我功能与后果行为相关，有助于识别有自杀行为风险的儿童。
