    Dispositional Influences and Individual Differences in Work Performance: Relationships of Goal Orientation, Growth Need Strength, and Conscientiousness.
    (2003-06-25) Dierdorff, Erich Clinton; Bob Pond, Committee Member; Paul Mulvey, Committee Member; Mark A. Wilson, Committee Chair; Bill Cunningham, Committee Member
    The purpose of this study was to investigate the roles of dispositional variables in affecting work performance. Study participants were criminal investigators from a state bureau of investigation (N = 158). The predictive potentials of growth need strength (GNS), learning orientation, performance orientation, and Conscientiousness were examined using structural equation modeling in relation to multidimensional work performance. All scales used for the study's constructs were subjected to a tetrad analysis prior to modeling in order to ensure unidimensional congeneric indicator sets. Three job performance constructs were incorporated: task performance as rating data, task performance as work activity data, and citizenship performance as rating data. GNS was shown to predict work activity task performance. Conscientiousness was found to predict citizenship performance. Learning orientation predicted both work activity task performance and citizenship performance, however the directions of the relationships were negative. Performance orientation was not found to predict any performance construct. None of the dispositional constructs predicted task performance as derived from ratings. Of the predictors, GNS and learning orientation displayed the highest latent correlation due to their similar conceptualizations. Using different operationalizations and sources for the latent performance criteria increased their measurement distinctiveness, as well as revealing differential predictive validities. The implications of these predictive validities and the importance of using a multidimensional approach to performance in future research are discussed.

    The Effects of Mode of Administration on Timed Cognitive Ability Tests
    (2006-04-28) Huff, Kyle; Mark Wilson, Committee Member; Paul Mulvey, Committee Member; Joan Michael, Committee Chair; John Fleenor, Committee Member
    Although widely used, there exists very little published research on the equivalence of web-based cognitive ability tests used for employee selection to their original paper-and-pencil versions. This issue is even further complicated by the limited research into the effects of proctoring on these types of tests. To investigate this issue, data was analyzed from the Wonderlic Personnel Test (WPT) and the Wonderlic Personnel Test-Quicktest (WPT-Q). Using the Differential Functioning of Items and Test (DFIT) procedure, data from 325 paper-and-pencil WPT administrations were compared to 325 web-based proctored administrations of the test. To check for the effects of proctoring, 108 proctored administrations of the WPT-Q were compared to 104 unproctored administrations again using the DFIT procedure. The results indicate that although the differences in administration produced low levels of differential item functioning (DIF), there is enough DIF to warrant conducting new validation studies when the mode of administration is changed.
