Systematically derived work dimensions: Factor analyses of the Occupation Analysis Inventory

Abstract

Developed the Occupation Analysis Inventory (OAI) for use as a taxonomic tool, derived a broad set of human work dimensions (factors) based on that questionnaire, and established some degree of construct validity for the resultant dimensions. 602 OAI work elements (items) were subjected to several factor analyses based on the ratings of 1,414 jobs on the elements and ratings of the elements on their requirements for 102 defined human attributes. The resultant factors were significantly related to the tested abilities of relevant job holders. It is concluded that job-rating factors should be (a) fairly reflective of the various types of work activities and conditions extant in the world of work and (b) unique in their coverage of information relevant to occupational education and career decision making.
