The STAXI-2 C/A is a 35-item self-report assessment tool that comprehensively yet concisely assesses the experience, expression, and control of anger while accounting for state and trait aspects of anger in 9-18 year olds.  The STAXI-2 C/A gives professionals working in the following contexts an orderly and intimate sense of key clinical aspects of anger by presenting a user-friendly “anger profile”. Click here for an overview of the STAXI-2 C/A scales and subscales.

Our global impact: Our measure has quickly become internationally recognized. We are currently working with researchers from the United States, Australia, Canada, India, South America, Eastern Europe, and the Middle East.  Our measure is currently being used here in the U.S. in a Center for Disease Control funded study. Dr. Brunner recently (2010) authored a book chapter discussing the value of the STAXI-2 C/A in assessing conditions such as ADHD in a book edited by Dr. Nancy Mather.  This chapter articulates how anger is often a significant but subtle contributor to common problems like ADHD, Anxiety, Asperger’s, and learning disabilities.

Anger has been vastly understudied, and yet is one of the dominant problems in the 21st century.  Anger is one of the most common reasons a child or adolescent is referred in school, clinical, medical, and forensic settings (Brunner & Spielberger, 2009).  Anger is a fundamental, yet complex emotion comprised of many facets that must be understood to fully grasp an individual’s “anger profile”. Anger is often mistakenly confused with similar concepts such as hostility and aggression, but this measure clearly distinguishes these concepts via clear definitions and applications.

The STAXI-2 C/A is a measure that is being used across school, clinical, forensic, and medical settings, due to its unique qualities, including the following:

  • Written at a 4th-grade reading level, the STAXI-2 C/A Rating Booklet is tailored for use by children and adolescents.
  • Reflects the 2007 U.S. Census population parameters via a post-stratification weighting procedure that was applied to the STAXI-2 C/A normative sample of 838 public school children and adolescents from several states.
  • Distinguishes temporary anger states from more trait-like or enduring conditions (e.g., whether a temper tantrum is a hallmark of a personality trait vs. a transient state-like event).
  • Enhances the ability to assess and diagnose the spectrum of conditions in which anger intensity as an emotional state is important (e.g., bipolar disorder, intermittent explosive disorder, reactive attachment disorder, oppositional defiant disorder, posttraumatic stress disorder).
  • Assesses the degree to which a child reacts only to specific negative events or more generally responds to diverse environmental events.
  • Assesses a child’s habitual anger coping style as either externalizing or internalizing (i.e., suppressive)
  • Assists in the determination of whether key aspects of a child’s anger profile may be related to problems with his or her health status (e.g., problems exacerbated by intense and/or frequent anger suppression).
  • Provides raw score to percentile and T-score conversions for the STAXI-2 C/A scales and subscales for both the total normative sample and the six normative age-by-gender groups.
  • Presents discriminant and convergent validity based on correlations with the Achenbach Youth Self-Report (YSR) DSM-Oriented and Syndrome scales for a subset of the normative sample and a clinical sample.
  • May be used as part of the diagnostic process, as a tool for monitoring the long-term effects anger may have on children and adolescents, and as a complement to threat assessment measures and procedures in a variety of settings.
