Dimensionality and Determinants of Self-Reported Cognitive Failures.

This research examined the dimensionality and the correlates of self-reported cognitive failures. The first goal was to determine what factors, in addition to a general one, are needed to explain self-reported cognitive failures. To explore this issue, both Rasch measurement and confirmatory factor analysis were employed. The second goal was to determine if cognitive failures might be predicted with personality factors, general cognitive ability, and the need for cognition. A sample of 552 USAF airmen responded to the Broadbent Cognitive Failures Questionnaire (CFQ), a Big-Five personality inventory, the Abstract Reasoning Test, the Speeded Cognitive Ability Test, and the Need for Cognition survey. Both Rasch modeling and confirmatory factor analysis indicated that a single factor dominated CFQ responses. Regression analysis showed that CFQ responses were predicted well by personality factors (R = .60).
