This psychometric study was designed to test the feasibility of measuring college students' preferences for developmental and prescriptive advising styles as separate constructs. Part 5 of the Academic Advising Inventory (Winston & Sandor, 1984b) was revised into two independent scales, one for measuring preferences for developmental advising and the other for measuring preferences for prescriptive advising. Results suggest that the two scales have a reasonable item structure, and the internal consistency reliability is reported to be modest. Of greater theoretical importance, the two scales are found to be largely independent. The practical implications of this independence are discussed relative to future applications and research.
