- ItemApplication of a nomological model of selection validity(Stellenbosch : Stellenbosch University, 2001-04) Bartmann, Tanya Justine; Duvenage, A.; Stellenbosch University. Faculty of Arts and Social Sciences. Dept. of Psychology.ENGLISH ABSTRACT: The purpose of this study was to determine the applicability of a nomological model for the assessment of psychological measurement validity with reference to personnel selection. The model, which can be traced to Thorndike (1949), Campbell and Fiske (1959), Nunnally (1967, cited in Duvenage, 1990), Guion (1974, cited in Duvenage, 1990), Binning and Barrett (1989) and Duvenage (1990), provides the evidential bases for two empirically founded validation strategies, namely criterion- and constructrelated validity. Theoretically, the Nomological Model for Psychological Measurement Validity Assessment proved to be applicable for validating that a measure is able to predict job performance. An easily understandable empirical investigation was required to verify the scientific utility of the model for selection validation. The model was used to validate the procedure for selecting machine operators in a large food manufacturer. The investigation illustrated that by utilising Route 1 of the nomological model, evidence of criterion-related validity, as described by legal and professional standards, is generated. Furthermore, the study indicated that by utilising Route 2 of the model, evidential requirements of construct-related validity as set by legal and professional standards are met. The results of the study proved that the Nomological Model for Psychological Measurement Validity Assessment is theoretically, professionally, legally and practically applicable for the validation of personnel selection procedures.
