Abstract	Based upon an occupational rating instrument entitled the Occupational Analysis Inventory (OAI), this study sought to produce a more stable and interpretable set of OAI job analysis factors. The study was designed (1) to obtain OAI ratings on an additional 600 jobs and thus enlarge the sample to 1,414 jobs and (2) to derive a meaningful set of work dimensions through factor analysis of the OAI ratings of the 1,414 jobs and estimate the stability of these derived dimensions. (The OAI is an instrument containing 622 work elements which are descriptions of work activities and conditions on which jobs and occupations are related. The work elements were generated within a work context paradigm of information input, mental activities, job behavior, and job outcomes.) OAI ratings were performed on written job descriptions of a 1,414 representative job sample. Eight separate sections of OAI elements were factor analyzed, and the resultant first-order factors were, in turn, subjected to an overall (higher-order) factor analysis. These analyses produced 132 first-order and 28 general higher-order work dimensions which are readily interpretable and meaningful. Analyses of factorial stability derived from two subsamples of 707 jobs each indicated some degree of stability in the derived work dimensions. It was concluded that the OAI dimensions should be broadly representative of the kinds of activities and conditions existent in the world of work. (Author/EM)
