Abstract:

A personal questionnaire, the Biographical Inventory, was part of the airman classification batteries up to 1959, with separate groups of items keyed for different job areas. This paper reports how the items of the most recent classification battery were assorted into 15 clusters on the basis of high correlations among items of each cluster. The scores for each group homogeneous keys were correlated with success in training for graduates of 8 Air Force training schools. The keys for Economic Level and Educational Success were the most generally valid. By multiple regression techniques, it was found that prediction of training school grades was almost as good from a regression equation based on graduates from all 8 schools as from separate equations for schools in each job area. Composite scores combining the inventory scores and the aptitude index were significantly more valid than the aptitude indexes alone average .43 vs .46 but a simplified combination of the 3 or 4 most valid inventory keys with the aptitude index proved equally valid. Under conditions existing at the time these data were collected, a short biographical inventory consisting of 4 or 5 of the homogeneous scales would add significantly to the validity of aptitude indexes derived from the last Airman Classification Battery.
