This study was designed to develop and test a screening approach to identify individuals with DSM-5 Intermittent Explosive Disorder (IED), a disorder of recurrent, problematic, impulsive aggression.
A screening approach to diagnose DSM-5 IED (IED-SQ) was developed by combining items related to life history of aggression and items related to the DSM-5 diagnostic criteria for IED. In study 1, the IED-SQ was studied in 72 adult participants; 33 that met DSM-5 criteria for lifetime IED and 39 that did not. In study 2, the IED-SQ was given to 740 undergraduates at a US university. Measures of aggression and anger expression and anger control were assessed in both studies.
In study 1, the IED-SQ demonstrated strong concordance with the best estimate diagnoses (Kappa =.80) for lifetime IED by DSM-5 criteria and good test-retest reliability (kappa =0.71). In study 2, the IED-SQ identified 4.3% of the undergraduate sample as meeting DSM-5 criteria for lifetime IED, a rate comparable to that in recent epidemiological studies. Participants identified as meeting DSM-5 criteria for lifetime IED, in both studies, had higher aggression scores, and higher anger expression, and lower anger control scores, compared to participants that did not meet DSM-5 criteria for lifetime IED.
These data suggest that the IED-SQ is a useful screening tool that can quickly identify the presence of IED by DSM-5 criteria in adults.
本研究旨在开发并测试一种筛查方法，以识别患有《精神疾病诊断与统计手册》第五版（DSM - 5）间歇性爆发障碍（IED）的个体，这是一种反复出现的、有问题的冲动攻击性障碍。
通过结合与攻击性行为生活史相关的项目和与DSM - 5中IED诊断标准相关的项目，开发了一种用于诊断DSM - 5 IED的筛查方法（IED - SQ）。在研究1中，对72名成年参与者进行了IED - SQ研究；其中33名符合DSM - 5终身IED标准，39名不符合。在研究2中，对美国一所大学的740名本科生进行了IED - SQ测试。在两项研究中均评估了攻击性、愤怒表达和愤怒控制的测量指标。
在研究1中，IED - SQ与DSM - 5标准下的终身IED最佳估计诊断显示出高度一致性（kappa = 0.80），并且具有良好的重测信度（kappa = 0.71）。在研究2中，IED - SQ识别出4.3%的本科生样本符合DSM - 5终身IED标准，这一比例与近期流行病学研究中的比例相当。在两项研究中，被确定符合DSM - 5终身IED标准的参与者，与不符合DSM - 5终身IED标准的参与者相比，具有更高的攻击性得分、更高的愤怒表达得分和更低的愤怒控制得分。
这些数据表明，IED - SQ是一种有用的筛查工具，能够依据DSM - 5标准快速识别成年人中IED的存在。
