The 57-item STAXI-2 consists of six scales, five subscales, and an Anger Expression Index that provides an overall measure of total anger expression. The STAXI-2 scales and subscales are listed below:
STAXI-2 Scales and Subscales:
Feel Like Expressing Anger Verbally
Feel Like Expressing Anger Physically
Anger Expression Index
The STAXI-2 State Anger scale assesses the intensity of anger as an emotional state at a particular time. The Trait Anger scale measures how often angry feelings are experienced over time. The Anger Expression and Anger Control scales assess four relatively independent anger-related traits: (a) expression of anger toward other persons or objects in the environment (Anger Expression-Out); (b) holding in or suppressing angry feelings (Anger Expression-In); (c) controlling angry feelings by preventing the expression of anger toward other persons or objects in the environment (Anger Control-Out); and (d) controlling suppressed angry feelings by calming down or cooling off (Anger Control-In).
An 11 years of age reading ability is generally required to complete the STAXI-2. Individuals rate themselves on 4-point scales that assess both the intensity of their anger at a particular time and the frequency that anger is experienced, expressed, and controlled. The normative sample for the STAXI-2 included more than 1,900 individuals (1,644 normal adults, 276 hospitalised psychiatric patients). Normative tables provide raw score-to-percentile and raw score-to-T-score conversions for STAXI-2 scale and subscale scores for the total normative sample, as well as by gender for three age groups: 16-19 years, 20-29 years, and 30 years and older. The STAXI-2 can be administered and scored by individuals with limited training. Interpretation requires professional training in psychology, psychiatry, or educational testing.
The STAXI-2 materials include the professional manual, reusable item booklets, carbonless self-rating sheets, and profile forms. The manual provides directions for administration and scoring, information on the construction and development of the STAXI/STAXI-2, guidelines for interpretation, validation studies, a summary of current research, and an extensive Bibliography. A profile form for graphing percentiles or T scores facilitates the interpretation of individual patterns in scale and subscale scores.
