Resumen de Correction for range restriction in meta-analysis revisited: Improvements and implications for organizational research
Huy Le, In-Sue Oh, Frank L. Schmidt, Colin D. Wooldridge
In this study, we present a more accurate method for correcting for range restriction (Case V) that expands upon Bryant and Gokhale's (1972) method. We further present detailed steps to incorporate the Case V method into Schmidt and Hunter's (2015) psychometric meta-analysis methods (both individual correction and artifact distribution approaches). We then evaluate the accuracy of the Case V method vis-à-vis existing methods. Monte-Carlo simulation results indicate that the Case V method provides very accurate estimates for the mean true score correlation and reasonably accurate estimates for the true standard deviation. More important, Case V almost always provides more accurate results than alternative methods (particularly, Case IV). To illustrate how the Case V method works with real data, we conduct a reanalysis of Judge, Heller, and Mount's (2002) meta-analysis examining the relationships between the Big 5 personality traits and job satisfaction. Results indicate that the true score correlations between the Big 5 traits and job satisfaction have been underestimated, whereas their true standard deviations have been overestimated. Implications for range restriction corrections in organizational research are discussed. [ABSTRACT FROM AUTHOR]
