Validation of an Air Force vocational interest inventory in the enlisted force was conducted to develop improved job placement techniques with a view toward practical application of results during initial counseling and job placement of enlisted personnel. The Vocational Interest-Career Examination (VOICE) was administered to 18,000 recruits during basic military training. After approximately one year on the job, they were resurveyed to determine the extent to which they were satisfied with their respective occupational assignments. Individual aptitude variables from the Armed Services Vocational Aptitude Battery (ASVAB) served as control measures. Multiple regression analyses were used to characterize relationships between entry-level interests and eventual job satisfaction and to explore moderating effects due to sex and aptitude scores. Results of analyses indicated that the VOICE subscales provided reliable and significant prediction of job satisfaction both for males and females. It was concluded that implementation of job placement procedures based on the VOICE would yield benefits for the enlistee in terms of increased job satisfaction, as well as for the service, which could expect higher productivity, fewer requirements for retraining, and improved job tenure in the enlisted force.
