A questionnaire packet assessing occupational preferences, activity preferences, and career self-efficacy expectations was administered to 2 samples of college students. The structural invariance of each data set (activity, self-efficacy, and occupation items) was examined for the 1st sample via principal-components analysis, and they correlated. The structure was found to be highly similar across data types. The items were then aggregated into 18 scales representing the spherical model of interests proposed by T. J. G. Tracey and J. Rounds (1996b). The 18 scales were found to fit the spherical model for both the original and validation samples. No gender differences in the structure of the scales were found, but there were gender mean differences found in the scale scores similar to results of past research.
