ABSTRACT This study was designed to develop a revised diagnostic criteria set for intermittent explosive disorder (IED) for consideration for inclusion in Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition (DSM-V). This revised criteria set was developed by integrating previous research criteria with elements from the current DSM-IV set of diagnostic criteria. Evidence supporting the reliability and validity of IED-IR ("IED Integrated Criteria") in a new and well-characterized group of subjects with personality disorder is presented. Clinical, phenomenologic, and diagnostic data from 201 individuals with personality disorder were reviewed. All IED diagnoses were assigned using a best-estimate process (eg, kappa for IED-IR >0.85). In addition, subjects meeting IED-IR criteria had higher scores on dimensional measures of aggression and had lower global functioning scores than non-IED-IR subjects, even when related variables were controlled. The IED-IR criteria were more sensitive than the DSM-IV criteria only in identifying subjects with significant impulsive-aggressive behavior by a factor of 16. We conclude that the IED-IR criteria can be reliably applied and have sufficient validity to warrant consideration as DSM-V criteria for IED.

    ABSTRACT: The vast majority of studies that have examined the latent structure of attention deficit/hyperactivity disorder (ADHD) in children and adolescents have concluded that ADHD has a dimensional latent structure. In other words, ADHD symptomatology exists along a continuum and there is no natural boundary or qualitative distinction (i.e., taxon) separating youth with ADHD from those with subclinical inattention or hyperactivity/impulsivity problems. Although adult ADHD appears to be less prevalent than ADHD in youth (which could suggest a more severe adult ADHD taxon), researchers have yet to examine the latent structure of ADHD in adults. The present study used a sample (N = 600) of adults who completed a self-report measure of ADHD symptoms. The taxometric analyses revealed a dimensional latent structure for inattention, hyperactivity/impulsivity, and ADHD. These findings are consistent with previous taxometric studies that examined ADHD in children and adolescents, and with contemporary polygenic and multifactorial models of ADHD.

    ABSTRACT: Aggression and violence represent a significant public health concern and a clinical challenge for the mental healthcare provider. A great deal has been revealed regarding the neurobiology of violence and aggression, and an integration of this body of knowledge will ultimately serve to advance clinical diagnostics and therapeutic interventions. We will review here the latest findings regarding the neurobiology of aggression and violence. First, we will introduce the construct of aggression, with a focus on issues related to its heterogeneity, as well as the importance of refining the aggression phenotype in order to reduce pathophysiologic variability. Next we will examine the neuroanatomy of aggression and violence, focusing on regional volumes, functional studies, and interregional connectivity. Significant emphasis will be on the amygdala, as well as amygdala–frontal circuitry. Then we will turn our attention to the neurochemistry and molecular genetics of aggression and violence, examining the extensive findings on the serotonergic system, as well as the growing literature on the dopaminergic and vasopressinergic systems. We will also address the contribution of steroid hormones, namely, cortisol and testosterone. Finally, we will summarize these findings with a focus on reconciling inconsistencies and potential clinical implications; and, then we will suggest areas of focus for future directions in the field.

    ABSTRACT: Intermittent explosive disorder (IED) is a psychiatric disorder characterized by repeated acts of affective aggression. Despite the diagnostic emphasis on the failure to control aggressive impulses, there is little research on affective processes and emotion regulation in IED; however, this research suggests possible dysfunctions in experiences of emotional intensity and lability. The hypothesis in the present study was that compared to individuals with other psychiatric disorders, and psychologically healthy individuals, individuals with IED experience greater negative affect intensity and emotional lability. Participants (N = 373) consisted of 202 individuals diagnosed with IED, 68 non-IED psychiatric controls (PC), and 103 healthy volunteers (HV). Emotion regulation was assessed using the General Behavior Inventory, the Affective Lability Scale, and the Affect Intensity Measure. Results showed that IED participants reported greater negative affect intensity and greater emotional lability across several emotion domains (e.g., anger, anxiety, depression) than PC and HV participants. These findings suggest that IED is characterized by more global emotion regulation deficits than those associated with anger alone. Aggr. Behav. 9999:1–9, 2014. © 2014 Wiley Periodicals, Inc.
