Convergence of conventional and behavior-based measures: Towards a multimethod approach in the assessment of vocational interests

The main aim of this study was to evaluate the usefulness of different techniques for the assessment of vocational interests. In an empirical study (n = 264) a questionnaire, a nonverbal test, several objective personality tests, and a semi-projective test were applied in one single session in a computerized setting. All tests enable the assessment of vocational interests with regard to the theory of vocational interests by Holland (1997). Results showed that highest correlations to a Holland-type questionnaire were found for the questionnaire and the nonverbal test. In general, the objective personality tests were less homogenous and showed lower correlations to questionnaires. Nevertheless, all different measures showed potential for the assessment of vocational interests. Improvements in the test material and scoring methods of the newly constructed tests are discussed and a model for the combined use of different assessment methods is presented. Future research directions and a discussion on the role of a multimethod assessment strategy in practice are given.
