Emotion attribution in intermittent explosive disorder

Accurate recognition of the emotions of others is an important part of healthy neurological development and promotes positive psychosocial adaptation. Differences in emotional recognition may be associated with the presence of emotional biases and can alter one's perception, thus influencing their overall social cognition abilities. The present study aims to extend our collective understanding of emotion attribution abnormalities in individuals with Intermittent Explosive Disorder (IED).

Two-hundred and forty-two adults participated, separated into groups of those diagnosed with IED according to DSM 5 criteria, Psychiatric Controls (PC), and Healthy Controls (HC). Participants completed a modified version of the Emotional Attribution Task wherein they attributed an emotion to the main character of a short vignette.

Participants with IED correctly identified anger stories and misattributed anger to non-anger stories significantly more often than PC and HC participants. They were also significantly less likely than HC participants to correctly identify "sad stories."

We utilized self-report assessments in a community-recruited sample. Replication in a clinical is suggested.

Findings from this study support the validity of IED as a diagnostic entity and provide important information about how individuals with psychiatric disorders perceive and experience emotional cues.
