A factor analysis of the Strong Vocational Interest Blank for men using the method of principal factors

A principal factors method factor analysis, made possible by the development of high-speed electronic computers, was done for the SVIB for men, using 227 military cadets in the 1st 2 yr. of college. Factors were rotated to simple structure by the H. F. Kaiser (see 33:5) Varimax procedure. 7 factors resulted, accounting for 83.5% of the total variance. The factors were defined by SVIB variables which had high loadings and high intercorrelations. Previous groupings into occupational families were challenged, as were the use of such groupings in previous studies. A recommended regrouping of SVIB variables was proposed.
