Criterion-Related Validity of the Least Preferred Co-Worker Measure

Summary Research on the cognitive complexity interpretation of the Least Preferred Co-worker (LPC) measure has failed to determine whether high or low groups are more cognitively complex. Additionally, prior works seldom explore the relationship between the LPC and related cognitive domains such as attitudes toward co-workers. Findings from a multistage sample of 2083 work supervisors illustrated that high and low, rather than moderate, LPC groups were more cognitively complex. This complexity was predictive of complexity of responses on the Trust in Recovered Alcoholic Scale. These findings suggest a curvilinear relationship between LPC scores and cognitive complexity.
