title: Lifetime and 12-month intermittent explosive disorder in Latinos.
abstract: This study examined the occurrence, correlates, and psychiatric co-morbidities of lifetime and 12-month intermittent explosive disorder (IED) and whether impairment due to IED differed across Latino groups. We used data on 2,554 Latino adults (75.5% response rate) from the National Latino and Asian American Study (NLAAS). Lifetime and 12-month prevalence of IED among Latinos were 5.8% and 4.1%, respectively. Unemployment was a common risk factor for both lifetime and 12-month IED. Protective factors for both lifetime and 12-month IED were having poor/fair English proficiency and being born outside the U.S. mainland. Cubans, Mexicans and other Latinos had lower odds of both lifetime and 12-month IED relative to Puerto Ricans, while Puerto Ricans with IED did not demonstrate worse impairment compared with the other groups with IED. Lifetime and 12-month IED were associated with several depressive, anxiety, and substance use disorders. Given its significant association with a wide-range of mental disorders, future research should consider the validity of IED as a unique disorder or whether it is merely a constellation of symptoms that accompanies a variety of mental diseases.
