Reliability and Validity of the Greek Version of the STAIC

Abstract

Summary: This study describes the adaptation of the State-Trait Anxiety Inventory for Children (STAIC; Spielberger, Edwards, Lushene, Montuori, & Platzek, 1973 ) to the Greek population. It was hypothesized that the STAIC would be able to measure children's state-trait anxiety levels. In the initial phase, a sample of 100 children, aged 9-12 years, was used in order to shape the final form of the inventory. In the final phase, two different samples (N = 875), aged 9-12 years, were used to test the validity and reliability of the inventory, using exploratory (Sample A; n = 425) and confirmatory (Sample B; n = 450) factor analyses. The results indicated that both scales possessed an acceptable internal consistency and reliability. The factor analysis in the total of the items indicated three factors, that is “absence of state anxiety,” “presence of state anxiety,” and “trait anxiety.” Also, confirmatory factor analysis (AMOS; Arbuckle, 1997 ) verified three factors. It is therefore concluded that the scales have a multifactorial structure and can be used among the Greek population to examine children's state and trait anxiety levels.
