Correcting validity estimates for selection procedures for range restriction typically involves comparing variance in predictor scores between all job applicants and applicants who were selected. However, some research on criterion-related and differential validity of cognitive ability tests has...

All measurements must contend with unreliability. No measure is free of measurement error. More attention must be paid to measurement error in all psychological research. The problem of reliability is more severe when rating scales are involved. Many of the constructs in...

The common practice in meta-analyses and in individual studies of correcting for direct range restriction even though range restriction is actually indirect has long been known to lead to under-correction, but this error has been assumed to be small. Using validity generalization data sets for 4...

The concept of differential validity suggests that cognitive ability tests are associated with varying levels of validity across ethnic groups, such that validity is lower in certain ethnic subgroups than in others. A recent meta-analysis has revived the viability of this concept. Unfortunately,...

We respond to the three comments on our recent article in the August issue of Academy of Management Perspectives (Le, Oh, Shaffer, & Schmidt, 2007), which highlights the importance of methodological advances in human resource research. By concentrating on tangential aspects of our article, these...

Relations between constructs are estimated based on correlations between measures of constructs corrected for measurement error. This process assumes that the true scores on the measure are linearly related to construct scores, an assumption that may not hold. We examined the extent to which...

In the current 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; Hunter & Schmidt, 2004) psychometric...

Meta-analysis has become a well-accepted method for synthesizing empirical research about a given phenomenon. Many meta-analyses focus on synthesizing correlations across primary studies, but some primary studies do not report correlations. Peterson and Brown (2005) suggested that researchers...

This paper investigates the extent to which differences in the likelihood of emerging as leaders are explained by genetic differences between individuals. Results indicated that approximately 17% of the variance in the latent construct of leadership emergence is explained by genetic effects that...

Purpose - Most of the studies in entrepreneurship depend on single-source rating methods to collect data on both predictors and criteria. The threat to effect sizes as a result of using single-source ratings is particularly relevant to psychology-based entrepreneurship research. Therefore, the...
