Chapter 11
Vocational Interests
work-related/occupational interests
HOW VOCATIONAL INTERESTS ARE MEASURED
surveys typically ask respondent to indicate his/her probable liking for various kinds
of occupations and work activities
Single-stimulus items: item states a single activity and you have to estimate how
much you’d like the activity on Likert scale
Forced-choice items: given two activities and you have to choose one form the two
SCORE REPORTS FROM VOCATIONAL INTEREST SURVEYS
most inventories will include scores for very broad areas or work; full-length surveys
will include scores for many more specific areas of work
two sets of scores:
one indicates how much you appear to like a given area of work
other indicates how similar you are to people who work in a particular
occupation
CONSTRUCTING VOCATIONAL INTEREST SCALES: EMPIRICAL AND RATIONAL
STRATEGIES
rational approach for developing scales to measure interests in areas of work:
start by writing items that seem clearly relevant to the various areas of work
empirical approach for developing occupational scales: diverse pool of items
administered to employed workers; then items selected according to how well they
distinguish the workers of one occupation from workers of all other occupations
combined
MAJOR DIMENSIONS OF VOCATIONAL INTERESTS
can’t use lexical approach therefore researchers use own subjective judgment
any given factor analysis of vocational interests might be somewhat biased, that
some areas of interest may be under-/over-represented
Holland (1966): 6 interest dimensions RIASEC
realistic, investigative, artistic, social, enterprising, conventional
simplified into two dimensions
People and Things
Ideas and Data
Campbell et al (1992) includes ADVENTURING dimension
Goldberg includes ^ and ERUDITION dimension
VOCATIONAL INTERESTS AND PERSONALITY

Document Summary
How vocational interests are measured surveys typically ask respondent to indicate his/her probable liking for various kinds of occupations and work activities. Single-stimulus items: item states a single activity and you have to estimate how much you"d like the activity on likert scale. Forced-choice items: given two activities and you have to choose one form the two. Major dimensions of vocational interests can"t use lexical approach therefore researchers use own subjective judgment any given factor analysis of vocational interests might be somewhat biased, that some areas of interest may be under-/over-represented. Holland (1966): 6 interest dimensions riasec realistic, investigative, artistic, social, enterprising, conventional simpli ed into two dimensions. Es didn"t correlate with any interest dimensions; realistic interest dimensions didn"t correlate with personality. E correlated negatively with realistic interests and adventuring. 11. 7. 2 relations with job performance r = . 20 to . 30. *dif cult to measure job satisfaction and job performance accurately. Conclusion: vocational interest inventories show moderate levels of criterion validity.
