    An evaluation of the construct validity of situational judgment tests
    Trippe, David Matthew (Virginia Tech, 2002-11-08)
    Situational judgment tests are analogous to earlier forms of "high fidelity" simulations such that an ostensible paradox emerges in the consistent finding of criterion-referenced validity but almost complete lack of construct validity evidence. The present study evaluates the extent to which SJT's can demonstrate convergent and discriminant validity by analyzing a SJT from a multitrait-multimethod perspective. A series of hierarchically nested confirmatory factor models were tested. Results indicate that the SJT demonstrates convergent and discriminant validity but also contains non-trivial amounts of construct-irrelevant method variance. Wide variability in the content and validation methods of SJT's are discussed as the reason previous attempts to find construct validity have failed.

    Reexamining the Role of General Cognitive Ability and Specific Abilities in the Prediction of Job Performance Using a Construct-oriented Approach: Not Much More Than g?
    Trippe, David Matthew (Virginia Tech, 2005-04-12)
    The purpose of the present study was to attempt to reconcile the seemingly overwhelming body of empirical evidence arguing for the preeminence of general cognitive ability in relation to specific abilities with the general resistance of the majority of Industrial-Organizational psychologists to such a position. The contention of the present study was that the primary evidence used to support the view that specific abilities are of little importance relative to general cognitive ability did not faithfully represent the classic selection model and was based on tenuous assumptions about the operationalizations of general and specific cognitive abilities. By virtue of being defined in un-interpretable terms with respect to content or function, prior operationalizations of specific abilities did not lend themselves to logical and theoretical relationships with job specific job performance. The general thesis of the present study was that if a "construct oriented approach" that is largely based on this classic selection model were implemented, a composite of psychologically interpretable job related specific abilities would prove equivalent or even superior to general cognitive ability in the prediction of job performance. Results suggest implementation of the construct oriented approach demonstrates potential for the value of this approach with respect to balancing criterion related validity and social equity.
