Description

Background:
The STAI is a validated 20 item self report assessment device which includes separate measures of state and trait anxiety. The original STAI form was constructed by Charles D. Spielberger, Richard L. Gorsuch, and Robert E. Lushene in 1964. The STAI has been adapted in more than 30 languages for cross-cultural research and clinical practice (Sesti, 2000). Various reliability and validity tests have been conducted on the STAI and have provided sufficient evidence that the STAI is an appropriate and adequate measure for studying anxiety in research and clinical settings (Sesti, 2000). McIntrye, McIntyre, and Silverio (in press) validated the STAI for Portuguese communities. Several items on the STAI were reversed coded (Items 1, 2, 5, 8, 11, 15, 16, 19, 20). Recommended for studying anxiety in research and clinical settings.

Reliability:
The stability of the STAI scales was assessed on male and female samples of high school and college students for test-retest intervals ranging from one hour to 104 days. The magnitude of the reliability coefficients decreased as a function of interval length. For the Trait-anxiety scale the coefficients ranged from .65 to .86, whereas the range for the State-anxiety scale was .16 to .62. This low level of stability for the State-anxiety scale is expected since responses to the items on this scale are thought to reflect the influence of whatever transient situational factors exist at the time of testing.
