The Japanese adaptation of the STAI form Y in Japanese working adults - The presence or absence of anxiety

Symptom endorsements and response patterns of 1,862 Japanese adult workers (1,509 males and 353 females) to the Japanese adaptation of the State-Trait Anxiety Inventory Form Y (STAI-JY) items, were examined in this study, The mean STAI-JY State and Trait anxiety scores of Japanese workers were substantially higher than those of American workers reported in the Manual, due primarily to the much higher scores of Japanese workers in responding to the anxiety-absent items, The correlations between the State and Trait anxiety-present scales and those of their anxiety-absent scales' counterparts were higher than those between the State anxiety-present and -absent scales and those of their Trait scales' counterparts. These findings suggested that responses to anxiety-present and -absent items should be considered independently in scoring the STAI-JY scales in Japanese working adults.
