Briefly describe at least one refinement to VG techniques describe in the reading.

What will be an ideal response?


Varies, but three that could be discussed are: 1. The estimation of the sampling error variance of the validity coefficient has been improved (e.g., Aguinis, 2001; Aguinis & Whitehead, 1997). 2. The application of Bayesian models allows for the use of previous distributions of validity coefficients and the incorporation of any new studies without the need to rerun the entire VG study (Brannick, 2001; Brannick & Hall, 2003; Steel & Kammeyer-Mueller, 2008). 3. There is an emphasis not just on confidence intervals around the mean validity coefficient but also on credibility intervals (Schmidt & Hunter, 2003a). The lower bound of a credibility interval is used to infer whether validity generalizes, so the emphasis on credibility intervals is likely to help the understanding of differences between VG and situation specificity tests.
