title: Reliability of the State-Trait Anxiety Inventory, Form Y in Japanese samples.
abstract: The internal consistency of the State-Trait Anxiety Inventory, Form Y was examined using data collected from Japanese participants by five diverse surveys, in which one included American university students. Cronbach coefficient alpha was calculated separately for state and trait items as well as for anxiety-present and absent items. The internal consistency was higher for the anxiety-absent items than those of the state and trait anxiety items, but this tendency was not clear for the anxiety-present items. The trait anxiety items showed the lowest internal consistency for all Japanese groups, whereas the anxiety-present items showed the lowest alpha for American university students. It can be considered that this difference might induce the difference in two--factor structure between Japanese and people in Western countries.
