How Valid Are Occupational Reinforcer Pattern Scores?
Gottfredson, Linda S.
A study examined the validity of using the Minnesota Job Description Questionnaire to measure occupational reinforcer patterns (ORPs). Although ORP profiles (twenty-one adjusted scales) were developed a decade ago to operationalize a key variable in the Theory of Work Adjustment (Lofquist and Davis, 1969), little validity evidence exists. An examination of the process by which adjusted ORP scores are created from the ipsative unadjusted scores suggested several threats to validity. In addition, correlations of the ORP scales with Census Bureau and Department of Labor Data on pay, education, occupational self-direction, and seventeen worker trait requirements show that (1) among the seven adjusted ORP scales for which there was good validation criteria, five were of questionable validity, (2) among the remaining fourteen adjusted reinforcers, several do not correlate in intelligible ways with the job characteristics data, and (3) the adjusted scores are no more valid than are the unadjusted scores. Discriminant analyses showed that the two sets of scales discriminate equally well among occupations, but different reinforcers are most important for separating the groups. The conclusion from the discriminant analyses is that whereas the unadjusted scales provide limited but useful information, the adjusted scores provide no new information and may be less interpretable than the unadjusted scores. Some specific recommended uses of the ORP scores should be examined. (Possible explanations for the failure of the scaling method to produce valid absolute ORP scores are discussed.) (Author/PV)
