A Pilot Study Comparing the Efficacy of Group Versus Individual Anger Management in Subjects With IED
The purpose of this study is to see how different forms of "Anger Management" compare in reducing anger and impulsive aggressive symptoms in people. "Anger Management" is a common form of "talk therapy" used to help people with anger problems. There are different types of "talk therapy" used to help people for anger problems and this study will compare two types of talk therapy in people with Intermittent Explosive Disorder (IED). IED is a disorder in which there are frequent and sudden outbursts of anger (yelling, throwing and breaking things, hitting people) that lead to problems with other people socially or at work.

|Official Title:||A Pilot Study Comparing the Efficacy of Group Versus Individual Anger Management in Subjects With Intermittent Explosive Disorder|
- Aggression interview (Overt Aggression Scale-Modified
- [OASM]) at midpoint 1 week post-treatment, 3-month follow-up and 6-month follow-up
- State-Trait Anxiety Inventory (STAXI) questionnaire at midpoint 1 week post-treatment, 3-month follow-up and 6-month follow-up
- Behavioral aggression measures (Taylor Aggression Paradigm [TAP], Point Subtraction Aggression Paradigm [PSAP]) at 1 week post-treatment

|Estimated Study Completion Date:||July 2006|
Intermittent Explosive Disorder (IED) is increasingly acknowledged as a common, potentially disabling psychiatric condition. Despite this, there are currently no empirically supported behavioral treatments for patients with IED. The purpose of the proposed study is to assess the short-term and long-term efficacy of a cognitive-behavioral treatment (CBT), previously found to be successful in treating dysfunctional anger, for treating IED. Secondary goals of the project are to:
- explore mechanisms involved in the successful treatment of IED, and
- examine individual differences associated with treatment response.
Seventy-two subjects meeting for both research and DSM IED criteria will be randomly assigned to either 12 weeks of individual CBT, 12 weeks of group CBT or 12 weeks of a wait-list control condition. Subjects will be assessed before and after therapy/wait-list as well as at 3 month and 6 month follow-up. Primary outcome measures will assess aggressive behavior, anger, and the presence of an IED diagnosis at post-treatment, 6-month follow-up and 12-month follow-up. Social and emotional information processing will be evaluated as potential mechanism of change. Trait aggression will be assessed as a potential moderating variable.
