Show moreDue to the increased use of technology in administering psychological measures, there has been a growing interest in establishing measurement equivalence of personality measures across paper-and-pencil and computer-based conditions. The present study examined the measurement equivalence of three personality measures across three administration conditions: paper-and-pencil proctored, computer-based proctored, and computer-based non-proctored. Participants were 415 undergraduate students, who were randomly assigned to the three conditions and completed measures of competitiveness, engagement, and pride in productivity. Adequate fit was found for a three-factor measurement model within each of the three conditions. Results from multi-group confirmatory factor analysis indicated good configural, metric, and scalar equivalence, as well as invariant uniqueness across the three conditions. Practically speaking, observed means can be compared across the paper-and-pencil, computer-based proctored and computer-based non-proctored conditions. Results of this study are consistent with previous research that showed support for measurement equivalence across paper-and-pencil and computer-based modes of administration. Future research with larger samples and employees should attempt to extend our findings to high-stake contexts, such as employment settings. M.S. in Psychology, May 2011 Show less
