The psychometric properties and validity of the multidimensional Test Anxiety Inventory TAI-G

The psychometric properties and the factor structure of an extended and mod ified version of the German Test Anxiety Inventory TAI-G (Hodapp, 1991) wer e investigated in a sample of N = 91 university students attending pedagogi cal courses of studies. The four subscales "emotionality", "worry", "lack o f confidence" and "interference" showed high internal consistencies and sat isfied the criterion of Rasch scalability. The factor structure of the ques tionnaire could be replicated. A number of significant relationships of the four scales to important test anxiety variables could be established in th e theoretically expected direction, substantiating the validity of the scal es. The use of the TAI-G for a differentiated diagnosis of four subcomponen ts of test anxiety can be recommended on the basis of the results of the pr esent investigation.
