| Abstract: | The degree of convergent validity among four methods of identifying vocational preferences was assessed via the decision theoretic paradigm. Vocational preferences identified by Holland's Vocational Preference Inventory (VPI), a rating procedure, and ranking were compared with preferences identified from a policy-capturing model developed from an evaluation of graphically portrayed vocational stimuli. The results from the policy-capturing method showed greater convergent validity with the rating and ranking procedures than did the VPI. Predictions made by the policy models were also found to relate more strongly to expressed vocational preference than predictions made by the VPI. The construct of vocational identity was found to moderate the degree of convergent validity among the methods, in that there was greater convergence among methods for individuals high in vocational identity than low. Over 50% of the the cross-validated variance in vocational identity was explained by a five-variable model composed of both decision theoretic and occupational concepts. The results are discussed in the context of using the decision theoretic paradigm to examine vocational preference and vocational identity in ways which may overcome some of the problems associated with more traditional methods. |
