Validation of the Minnesota Vocational Interest Inventory for vocational high school boys.

Abstract

The concurrent validity of the MVII was investigated with over 1000 vocational high school boys in Grades 9 and 12 in Buffalo, New York, schools. Scores of boys in particular trade curricula were checked against relevant MVII scales. At Grade 12, the food, electrical, and printing trade choices were well predicted; students in building trade, machinist, and mechanical programs were not well spotted. Similar results, but less encouraging, were found for the Grade-9 sample. With 1 student sample only (electrical), aptitude test data were unrelated to MVII scores. Students with "high" academic or shop school averages earned higher MVII criterion scale scores than did others.

Research in counseling psychology: 1964.

“…With measures other than the SVIB, Barnette and McCall (1964) presented validity evidence for the Minnesota Vocational Interest Inventory used with ninth and twelfth grade boys, and King and Norrell (1964) factor analyzed the Kuder Preference Record-Occupational, Form D, and were not able to identify a Business Detail factor.…”

TESTING THE TEST: The Minnesota Vocational Interest Inventory

“…The results of those studies are reported in Clark's book and have been helpful in determining the clusters on the profile. Barnette and McCall (1964), working with the MVII in a technical school setting, found the inventory worked well with students in the food, electrical, and printing curricula, but reported less favorable results with students in the building trades and mechanical areas. Why the scales worked in some areas and not in others is a puzzle; perhaps it was because all of their students had to select some area and those who had no strong interests were more likely to choose to spend their time in the woodworking or automotive shops, Barnette and McCall also reported some data on race differences; their conclusion was that there is very little difference between Negroes and white students on the MVII scales.…”

“…A verification scale to identify carelessly or incorrectly marked MVII answer sheets was developed by scanning the item responses of the TIG group and selecting the very unpopular items, using the rationale that anyone who selected those items was not paying attention to what he was doing (Campbell and Trockman, 1963). Later research has shown that selecting items in that fashion simply gives one an MF scale for the MVII which, for many populations, is not a verification scale at all (McCall, 1964). The verification scale has been retired.…”
