[A questionnaire for assessing anger and expression of anger]

The State-Trait Anger Expression Inventory (STAXI) developed by Spielberger is a measure for state- and trait-anger and three different forms of anger expression. People differ in the extent to which they express anger overtly and directly (anger out), how often anger feelings are hold in or suppressed (anger in) or in the extent to which they are able to control their angry feelings or their overtly expressed anger (anger control). The scales are developed to determine the relevance of individual dispositions to express anger in the etiology and course of psychosomatic illness like hypertension, coronary heart disease etc. The present report is a summary of the research reports presented by Schwenkmezger and Hodapp (1986, 1989). It describes the development of the German adaptation of the STAXI, including itemmetrical and factor analytic results, detailed research on construct validity, and first experimental analyses.
