The purpose of this study was to dertermine the relationship between the Youth Occupational Interest Survey (YOIS) and Career Maturity Inventory Attitude Scale (CMI). A sample of 422 freshmen, 162 males and 260 females, was got from Taiwan Normal University. The data, including twenty scores from YOIS and six Scores of CMI, were analyzed by t test and canonical analysis. The results were as followed. (1) There were significant differences between the two sexes in their occupational interests. (2) Significant canonical correlations were found between YOIS and CMI, one on male subjects and two on females. (3) The high negative loading on female CMI structure coefficients showed that some vocational preferences related to the uncertainty of self-concept. (4) The proportion of the redundancy index between YOIS anc CMI was small, which indicated that other related fators such as work value, aptitudes, personality, etc. needed further exploring.
