A modified iterative factor analytic method was applied to item responses of 346 male students in four community colleges in order to construct three experimental scales for the measure of motivation. A fourth scale, which appears to be a measure of goal-deficiency, was also developed. The four scales--tentatively identified as Intrinsic Motivation (IM), Self Enhancement (SE), Person Orientation (PO), and Goal Deficiency (GD)--were found to be relatively independent of one another and to have a high degree of reliability with respect to test-retest stability. Provisional norms, based on 649 females and 650 males, were established. Item content and correlates of the scales suggest that the four new experimental scales should have special relevance for description and analysis of motivation in relation to work and education.
