The predictive validity of a vocational interest inventory-"Ramak": Seven year follow-up

The purpose of this study was to test the predictive validity of the Ramak-a vocational interest inventory based on Roe's (1956) classification of occupations. In this follow-up, 81% of the original sample, tested 7 yr earlier, was located. These Ss responded to a questionnaire which inquired into their vocational choice and vocational choice satisfaction, together with retesting of the Ramak. Results showed that: (a) The median interpersonal test-retest reliability was .412 for males and .401 for females, while the median within-the-person profile stability was .535 for males and .700 for females; (b) With few deviations, for each occupational field the Ss occupied in that field had the highest interest in that field; (c) With the exception of Arts and Entertainment in both sexes, for each interest field Ss who had the highest score were those engaged in that field; (d) The correlation between vocational choice satisfaction and the interests in the relevant field was .405 and .294 for males and females, respectively; (e) For both sexes, Ss occupied in their highest-scoring interest field were more satisfied with their vocational choice than those who were not. The effectiveness of the Ramak in vocational counseling is evaluated.
