Factor structure of the State-Trait Anger Expression Inventory.

The assessment of anger has received increased attention because of growing evidence that anger and hostility are related to heart disease. Research on anger assessment has also been stimulated by the development of psychometric measures for evaluating different facets of anger, such as the State-Trait Anger Expression Inventory (STAXI). In this study, factor analyses of the responses of a large sample of university students to the 44 STAXI items identified 7 factors. Of these, the first 6 factors closely corresponded with the 6 STAXI scales and subscales: State Anger (S-Anger); Trait Anger Temperament and Reaction; and Anger-In, Anger-Out, and Anger-Control. All 10 STAXI S-Anger items had salient loadings on the 1st factor for both sexes; the 7th factor also consisted primarily of S-Anger items. Factor analyses of responses to the 10 S-Anger items clearly confirmed two S-Anger factors for both sexes: Feeling Angry (e.g., "I am furious") and Feel Like Expressing Anger (e.g., "I feel like hitting someone").
