The goal of this clinical study was to examine the frequency and clinical features of pervasive developmental disorder (PDD) relative to suicide attempts by adolescents.
Ninety-four adolescent patients under age 20 participated in this study; it was a consecutive study of individuals who had attempted suicide and had been hospitalized for inpatient treatment.
Twelve of the 94 subjects (12.8%) were diagnosed with PDD. The ratio of males in the PDD group was higher than that in the non-PDD group (P=.017). There was a significant difference between the two groups regarding the rate of patients having mood or anxiety disorder (P=.037).
This study indicates that PDD should always be a consideration when dealing with adolescent suicide attempts.
本临床研究的目的是调查广泛性发育障碍（PDD）相对于青少年自杀未遂的发生率及临床特征。
94名20岁以下的青少年患者参与了本研究；这是一项对自杀未遂并已住院接受 inpatient 治疗的个体的连续性研究。
94名受试者中有12名（12.8%）被诊断为PDD。PDD组中的男性比例高于非PDD组（P = 0.017）。两组在患有情绪或焦虑障碍的患者比例上存在显著差异（P = 0.037）。
本研究表明，在处理青少年自杀未遂事件时，应始终考虑PDD。
