A test was developed to predict job satisfaction on the basis of psychological needs satisfaction. A short questionnaire consisting of six multiple choice questions was designed to measure (1) expressed degree of need satisfaction among 14 pre-selected psychological needs (job security, outdoor work, good pay, competition, esteem, leadership, dependence, social service, self-actualization, power, congeniality, advancement, independence, and interesting duties) and (2) self-evaluated degrees of satisfaction as reflected in a seven-factor Likert-type scale. The questionnaire was administered to 472 workers employed by the federal government. Sampled were employees in 29 different kinds of jobs within five major occupational groups (professional, management, clerical, service, and trades/manual occupations). Structural analyses were performed to measure the extent to which different values in the job satisfaction variable were accompanied by--or perhaps dependent upon--changes in the need satisfaction strength variable. The level of correlation found suggests that the technique has marked construct validity as well as a useful level of predictive value in estimating worker job satisfaction from obtained measures of experienced needs satisfaction.
