abstract="OBJECTIVE: 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. <br><br>METHODS: 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. <br><br>RESULTS: 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. <br><br>CONCLUSIONS: 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.<br><br>Copyright © 2016 Elsevier Inc.
