This research was designed to identify and assess the effects of a job's context and naturally occurring job content changes upon the job attitudes of 709 Air Force radio operators. The first of two phases of the investigation identified specific job types within the radio operator career field at two points in time, and determined the flow of personnel from one of eight job types to another over a seventeen-month period. In the second phase, a series of multiple linear regression analyses were employed in the prediction of job attitude criteria consisting of perceived job interest, felt utilization of talents and training, and overall satisfaction. Results indicated that individual inputs such as months on the job (MOJ) and total active federal military service time contributed significantly in predicting job interest and felt utilization; and MOJ, aptitude, and grade contributed to the prediction of overall job satisfaction. In addition, situational inputs such as number of tasks performed and average task difficulty substantially improved prediction of attitudes. Interest and overall satisfaction tended to be more highly associated with an individual's current job while felt utilization tended to be associated with both the individual's current and past job experiences. Implications for job satisfaction predictions include improving job perceptions through personnel, task, and duty assignment policies as an approach to job enrichment. (Author/KC)
