Study aims to test for the hypothesized dimensional structure of a revision and extension of the Orientation and Motivation Inventory (OMI) and to check for sex differences. The 12-scale inventory was administered to 307 high school and college men, and to 184 college women. The intercorrelations among the half scale scores for the men and for the women were separately factor analyzed and rotated. For men, 10 of the factors, and for women, 11 of the factors hypothesized were confirmed. Five second-order dimensions were identified in both men and women. The scores were next applied in discriminant function analyses to differentiate male and female subjects allocated to one of Holland's six personality types. The results provide some support for the validity of the motivational scales.
