Which Aspects of a Semistructured Interview, Besides Cognitive Ability Tests, Contribute Incrementally to Predicting the Training Success of Air Traffic Controller Trainees?

This study examined whether a semistructured interview is valid in predicting training performance in theoretical and simulation examinations and overall training success; which aspects of the interview show incremental validity over cognitive ability tests; and whether additional variables enhance the prediction from the interview. The sample involved data from 337 trainees of the G erman A ir N avigation S ervice P rovider selected by the G erman A erospace C enter and 657 (interview) and 6,885 (cognitive ability) candidates being the corresponding reference samples. Findings indicate incremental validity of the interview over the cognitive ability tests. Additional variables contributed only to the prediction of theoretical examination performance. Attention, general motivation, and social competence predicted the criteria best, particularly the theoretical examination performance and overall training success.
