Аннотация:Administered questionnaires to 291 scientists working in research and development laboratories. Results of a factor analysis indicate that job-involvement attitudes, higher order need-satisfaction attitudes, and intrinsic-motivation attitudes should be thought of as separate and distinct kinds of attitudes toward a job. These 3 types of attitudes related differentially to job design factors and to job behavior. Satisfaction proved to be related to such job characteristics as the amount of control the job allowed the holder and the degree to which it is seen to be relevant to the holder's valued abilities. Satisfaction was not related to either self-rated effort or performance. Job involvement, like satisfaction, bore a significant relationship to certain job characteristics; unlike satisfaction, however, involvement was positively related to self-rated effort. Intrinsic motivation was less strongly related to the job characterisitcs measured, but was more strongly related to both effort and performance than was either satisfaction or involvement. (15 ref.)
