A new meta-analytic approach

Article Abstract:

A new meta-analytic approach for assessing the generalizability of correlations or criterion-related validities is presented. The new approach incorporates specific procedures for estimating the sampling variance of corrected and uncorrected correlations. A major advantage of the new approach is the ease with which studies without any sample-based artifact data, with partial sample-based artifact data, or complete sample-based artifact data can be incorporated together into a practical procedure for meta-analysis. Monte Carlo studies indicated that the new procedure is consistently more accurate in estimating the mean and variance of true validities than the current correlation-based procedures. The implications of the new approach and its procedures for more appropriately estimating confidence limits, magnitudes, and the generalizability of correlations are discussed.

A new approach for utility analysis

Article Abstract:

A new utility analysis approach is presented. It is demonstrated that the new approach does not require the direct estimation of the most problematic component of current utility analysis equations, the standard deviation of Y. The parsimony of the new approach provides the potential for more directly linking decision-theoretic utility analysis with economic and accounting concepts. The development of the new approach highlights the many necessary and untested assumptions of current utility models. It also points to a need for reassessing the psychometric validity of correcting for criterion unreliability in utility analysis. Furthermore, the CREPID and 40% and 70% rules for estimating the standard deviation of Y are shown to be special cases of the new approach. Research on the efficacy of the assumption and applicability of the new approach is advocated. (Reprinted by permission of the publisher.)

Age discrimination in simulated employment contexts: an integrative analysis

Article Abstract:

In the area of age discrimination in simulated employment settings, the present study meta-analytically tested 4 primary hypotheses derived from the social psychological stereotyping literature, referred to as the in-group bias, job information, salience, and job stereotype hypotheses. In general, the results supported the in-group bias, job information, and salience hypotheses, in that younger raters tended to give less favorable ratings to older workers when they were not provided with job-relevant information about the workers and when they concurrently rated old and young workers. Future research, including the initiation of research on economic-based age stereotypes, as well as practice directions related to valuing age diversity in organizational stakeholder groups are discussed.
