The present report concerns a further investigation of the dimensions of worker-oriented job variables through use of the Worker Activity Profile WAP. In this study, factor analyses similar to Gordon and McCormicks were conducted, using a job sample based on percentages of people within various occupational areas. The resulting factors were then compared with Gordon and McCormicks by use of the coefficient of congruence. The results of six separate factor analyses of WAP item groups were judged to be generally meaningful. Of the 32 factors obtained in this study, 16 were classified as comparable to factors from Gordon and McCormicks study, two others appeared from inspection to be similar to two of their factors, and eight factors showed a noticeable relationship with factors obtained by Gordon and McCormick. It was concluded that there are fairly stable and meaningful dimensions of jobs that characterize work in worker-oriented terms. These dimensions are sufficiently structures so that they emerge through factor analysis despite differences in the choice of bases for job samples used. Author
