A multivariate model for the occupational placement decision

Tested the applicability of L. F. Schoenfeldt's assessment-classification model to placement decisions within a large industrial organization. Eight developmental-interest dimensions describing the early life behaviors, values, and interests of 438 blue-collar workers were formulated. Job analysis identified 2 clusters of positions that were homogenous within and differentiated between each other on relevant job attributes. One cluster consisted of process operator positions and had 102 incumbents with more than 6 mo of service. The other cluster was composed of heavy equipment operator positions that had 148 incumbents. The 250 incumbents were randomly divided into validation and cross-validation groups. A discriminant analysis was conducted on the validation group to develop a linear combination of the life history factors that maximally differentiated the 2 job families. Cross-validation demonstrated that 3 psychologically meaningful dimensions discriminated between the groups at both statistical and practical levels of significance. The process operators were more likely to be raised in an urban environment, to have a more favorable self-image, and to prefer standardized work schedules.
