State-Trait Anger Expression Inventory-2 (STAXI-2)

The State-Trait Anger Expression Inventory-2 (STAXI-2) assesses various areas of anger and the traits of experiencing anger. A common use for the STAXI is to collect information for people with anger issues and for creating treatment plans.

Participants are asked to respond to 57 items using a 4-point scale (“Not at all” to “Almost Always”). Approximately 12 to 15 minutes is required for completion. STAXI is the revised edition which had only included 44-items.


Charles Spielberger, 1999

Reliability and Validity

The State-Trait Anger Expression Inventory is a well-known instrument and it has supported data for relatively high reliability and validity. In the authors test manuals, the psychometric properties included high alpha coefficients for internal reliability for all subscales except for the Trait Anger Scale/Angry Reaction (0.73-0.76). There is extensive showing of validity for the original versions of STAXI but none for the current edition. Concurrent validity of the original STAXI is strongly presented with correlations with the Multiphasic Inventory (Hostility and Over Hostility Scales), Buss-Durkee Hostility Inventory, and the Eysenck Questionnaire (Psychoticism and Neuroticism).
