The study attempted to demonstrate significant relationships between systematically derived occupational descriptors and selected measures of worker characteristics in the affective domain. The predictor variables were derived from the Occupation Analysis Inventory (OAI) and consisted of work-dimension scores describing occupations in terms of work activities and conditions, and attribute-requirement estimates characterizing occupation in terms of various human requirements. The worker variables were based on responses of job incumbents to selected interest, need, and satisfaction questionnaires. The results of various statistical analyses offered consistent support for the validity of the OAI descriptors. It was concluded that the OAI work-dimension scores and attribute-requirement estimates for occupations possess demonstrated relevance to the interests, needs, and satisfactions of job incumbents and that these occupational variables should prove useful for a number of research and development purposes.
