This empirical study investigated the relation between ego defense mechanisms, diagnoses, and suicidality among 200 adolescent psychiatric patients ages 12 to 16 years. Based on a structured diagnostic interview, adolescents were divided into three groups: suicide attempters, suicidal ideators, and nonsuicidal patients. Using the Defense Mechanisms Inventory (DMI), suicidal adolescents scored higher on the defense of turning-against-self and lower on reversal, as compared to nonsuicidal adolescents. Although suicide was significantly more common among adolescents with an affective disorder, turning-against-self remained significantly associated with suicide attempt even when diagnosis was controlled for. Results demonstrate the importance of defense mechanisms in understanding adolescent suicidal behavior.
这项实证研究调查了200名年龄在12至16岁的青少年精神病患者的自我防御机制、诊断结果与自杀倾向之间的关系。基于结构化诊断访谈，青少年被分为三组：自杀未遂者、有自杀意念者和无自杀倾向患者。与无自杀倾向的青少年相比，使用防御机制量表（DMI）评估发现，有自杀倾向的青少年在“自我攻击”防御方面得分较高，而在“反向作用”防御方面得分较低。尽管情感障碍青少年的自杀情况明显更为常见，但即使在控制诊断因素后，“自我攻击”防御仍与自杀未遂显著相关。研究结果表明，防御机制在理解青少年自杀行为方面具有重要意义。
