Objective:
The present study examined potential treatment outcome predictors of a multicomponent cognitive behavioral intervention for intermittent explosive disorder (IED).
Method:
The sample (n = 64; 22 female) consisted of individuals with a current diagnosis of IED that completed treatment across three study trials. Treatment outcome predictors assessed included demographic variables, psychiatric comorbidity, symptom severity, and treatment motivation/engagement. Treatment outcomes were (a) change in number of past-week aggressive acts from pretreatment to posttreatment and (b) presence of IED diagnosis at posttreatment.
Results:
Results indicated those who endorsed lower trait anger were more likely to remit from IED diagnosis at posttreatment. No other variables were found to significantly predict treatment outcome.
Conclusions:
These findings support the notion that cognitive behavioral therapy can be effective for a wide range of individuals with IED, with little variation in efficaciousness based on presence of demographic characteristics, comorbid disorders, or treatment motivation/engagement. This seems to be particularly the case for individuals with lower levels of trait anger. (PsycInfo Database Record (c) 2024 APA, all rights reserved).
