The Turkish edition of the Test Anxiety Inventory (TAI-T) was accomplished in three stages, each stage constituting an independent study with new samples. In the first study, using bilingual Turkish high school and college students, the transliteral equivalence between the Turkish and English TAI items were achieved. The second study, using a larger sample of monolingual Turkish students, tested the stability, item homogeneity and internal consistency of this form. In the third study, where heterogeneous monolingual Turkish student samples were utilized, the criterion and construct validities of the TAI-T were assessed. Moderate significant correlations between the TAI-T and various personality measures as well as academic achievement were obtained and provided support for the concurrent, predictive and construct validity of the instrument. Factor analysis yielded more than two factors for this form. Data were interpreted to suggest a three factor (worry, emotionality and nervousness) structure for the Turkish TAI. (Author/JAZ)
