Factor Structure of the State-Trait Anger Expression Inventory for Middle-Aged Men and Women

Recently, Forgays, Forgays, and Spielberger (in press) reported the first exploratory factor analysis of the total 44-item State-Trait Anger Expression Inventory (STAXI) by gender. The analyses were based on a sample of over 700 male and female university students and identified quite well six of the original STAXI scales and subscales. In addition, a seventh factor, "Feel-Like-Expressing-Anger," emerged for women. In the present study, we examined the STAXI responses from a middle-aged adult population. Exploratory factor analyses replicated the majority of the original structure of the STAXI measure including a Feel-Like-Expressing-Anger factor for men and women. In addition, we employed confirmatory factor analyses and cross-validation procedures to test the validity of Spielberger's (1988) AHA! model. Based on these procedures, we found (a) that a seven-factor model provided a better fit than a six-factor solution for each gender and (b) evidence of robust gender differences for two factors: Feel-Like-Expressing Anger and State Anger. These gender differences are consistent with the social costs for anger expression in women and the social benefits for men.
