| Summary: | This paper discusses a series of studies investigating the construct-related and criterion-related validity of Cogscreen-Aeromedical Edition. The fit of previously proposed factor models were examined using confirmatory factor analysis on a sample of 1330 commercial airline pilot candidates. It was posited that the Cogscreen-AE model proposed in the extant literature would not adequately fit the data due to issues pertaining to psychopathic limitations, small sample sizes, and restricted age samples. As expected, results of Study IA revealed that the Cogscreen-AE model did not fit to the data. As such, a psychopathic assessment using exploratory factor analysis was subsequently conducted in Study IB to obtain the best fitting factor structure. In Study 2, a cross-validation sample of 1330 commercial airline pilots was used to replicate the best fitting factor structure obtained in Study IB using confirmatory factor analytic techniques. The results were consistent with expectations that a correlated factor model would fit the data better than an orthogonal model, with fit indices ranging from .94 to .97. The factor structure obtained in Study 2 was replicated in Study 3 and accounted for a total of 74% of the variance. A field test of 605 pilots was conducted by entering the factor scores of the developed measure into a hierarchical regression analysis, after controlling for age. Composite scores of pilot training performance ratings were the criterion of choice, consisting of Flight Task Performance, Contextual Performance, Task-Related Performance, and General Pilot Performance. Tracking Ability and Visual Associative Working Memory served as significant predictors of composite pilot training performance scores, contributing incremental variance after controlling for age. Implications of the findings and limitations of the present study are discussed. |
