Psychometric Properties of Farsi Version of the Spielberger‘s State-trait Anger Expression Inventory-2 (FSTAXI-2)

The present study examines the psychometric properties of the Farsi version of Spielberger's (1988) State-Trait Anger Expression Inventory (STAXI-2) for Iranian university students. 1140 students were selected from Tehran University, and Spielberger‘s State-Trait Anger Expression Inventory-2 with one of the five instruments were completed by them. These instruments consisted of Multi-dimensional Anger Inventory (MAI; Siegel, 1986, ), Over-controlled Hostility Scale (O-H: Megargee, Cook, & Mendelson Bortner, 1976) Oxford Happiness Inventory (OHI; Argyle, 1998), Emotional Intelligence (FEIS- 41; Besharat, 2007) and NEO-Five Factor Inventory (NEO- PI; Mc Cera & Costa, 1999). The results showed a significant relation between STAXI-2 and its subscales, and the majority of scores on parallel instruments. Factor analysis indicated the existence of multi-factorial model that consistent with the original structure. According to the findings, STAXI-2 has a reasonable reliability, internal consistency, and construct, content, concurrent, convergent, divergent and discriminant validity. Therefore, this tool can be used in research and clinical settings.
