Reliability estimated by scoring key equivalence across samples

Abstract

Estimated reliability of a biographical inventory (BI) by correlating scores from preexistent BI scoring keys with scores from empirically constructed BI scoring keys. Exp. I demonstrated that a preexistent scoring key, developed on National Aeronautics and Space Administration scientists to predict creativity, was correlated .87 (n = 294) and .91 (n = 296) with scoring keys empirically constructed to predict creativity for 2 samples of industrially employed scientists and engineers. Exp. II demonstrated that preexistent scoring keys, constructed on 11,246 university freshmen to predict GPA, were correlated .88 with scoring keys empirically constructed to predict GPA for high school students. Test-retest reliability estimates and validity generalization estimates support the above results. (PsycInfo Database Record (c) 2025 APA, all rights reserved)
