The Vocational Interest Survey (VIS) is a set of six questionnaire scales for measuring vocational interest. It is designed for Australian users and is consistent with Holland's theory that there are six basic career categories. This paper discusses the development of the VIS and presents some technical data on the questionnaires. Items were provided by the users (in the form of free-association responses) rather than by psychologists. Based on those items, a pilot questionnaire was prepared, which contained three separate lists of 138 occupations, 105 study courses, and 152 activities. Complete-link clustering was used to develop six temporary groups of occupational items. The 105 items relating to study courses were then correlated with the six experimental scales. Further item-analyses were conducted to produce six combined jobs/study courses scales with maximum internal consistency. Finally, activity items were selected and added to the combined jobs/study courses. Reliability of VIS scales was assessed using measures of internal consistency, split-half reliability, and test-retest coefficients. In addition, the intercorrelations of the six VIS scales, the construct validity of the VIS, and the relationship between vocational interests on the VIS and career related characteristics were measured. The appendix provides a listing which summarizes the overall responses to each item. (JAZ)
