The purpose of this study is to assess the factorial structure regarding a commercially available computer-based intelligence test given to U.S. Air Force (USAF) pilot training candidates (manned as well as unmanned) during medical flight screening. Principal components analysis was conducted on the intelligence test scores from the computer-based Multidimensional Aptitude BatterySecond Edition (MAB-II). This test was administered to 10,612 USAF pilot training candidates. Subtest and measurement model correlations were estimated. Confirmatory factor analysis using the MAB-II showed positive correlations between specific subtests. The results of factor analyses suggest MAB-II intelligence test scores are best suited to a three-factor model unique to the rated USAF pilot population. In addition to verbal- and performance-based intelligence quotients, a visual reasoning and working memory intelligence quotient composed of the arithmetic, digit symbol, and spatial analyses subtests appears in test scores for this population. This finding is in contrast to the two-factor measurement model used for the general population. The results of the study support an alternative way for conceptualizing and reorganizing MAB-II intelligence test subtest scores to better account for the relationship between test scores from USAF pilot training candidates. The relationship of these test scores must be well understood to effectively evaluate how specific cognitive aptitudes are related to (and/or affected by) changes in any particular subtest. Rather than just measure global cognitive ability, it is recommended that neuropsychologists and clinical psychologists remain sensitive to the pattern and factor analyses of subtests that comprise the global score of intelligence for this commercially available intelligence test. This is especially important when the purpose of a psychological evaluation is to assess the cognitive strengths and weaknesses of a specific individual (and his or her readiness to participate) in the unique high-risk, high-demand nature of USAF military pilot duties.
