Refinement of Scoring Procedures for the Basic Attributes Test (BAT) Battery
Abstract
The Basic Attributes Test (BAT) is a multiple aptitude computer-based battery designed to measure individual differences in psychomotor coordination, cognitive abilities, personality, and attitudes. The Air Force plans to operationally implement the BAT as a pilot candidate selection instrument in the near future. Scores from the Air Force Officer Qualifying Test, BAT, and biographical information will be combined in a new pilot candidate selection composite to predict undergraduate pilot training outcomes. Although much useful research has been done in the BAT battery, the need for additional psychometric research to improve test scoring procedures and predictive efficiency was identified. The purpose of this study was to investigate (a) the internal consistency of hem-level test scores, (b) the effects of alternative scoring procedures (e.g., treatment of outliers, data transformations, alternate scoring algorithms) on internal consistency and validity, and (c) the factor structure of the BAT. Results showed that (a) internal consistencies of most BAT scores are acceptable, indicating that the constructs are being measured reliably, (b) neither censoring outlying data points nor transforming data had a significant impact on internal consistency or validity of BAT scores, (c) few alternative scoring procedures improved BAT score validity, (d) test scores relate to a meaningful factor structure, and (e) BAT scores can be combined into an efficient model for the prediction of undergraduate pilot training performance.. ..
