What is the validity/reliability of WorkPlace Big Five Profile 4.0?
The Coefficient Alpha for the WorkPlace is .83. The Coefficient Alpha for the life-at-large Five-Factor Model assessment, NEO PI-R, is .9. Increasing the WorkPlace Coefficient Alpha to .9 would require many additional questions, thus making the assessment less efficient for the workworld. Predictive validity is measured by performing a validity study for a particular job using the instrument which will provide a target profile. That target profile is then used to hire candidates into the job and to study the results of performance for those candidates selected based on the target profile. The predictive validity of WorkPlace correlates successfully with the industry standard, NEO PI-R. If you are interested, the Center for Applied Cognitive Studies has validity case studies that can be shared.
