The assumptions individuals make about their personal behaviors have received extensive attention, particularly the concepts of locus of control and self-efficacy. An additional concept, change orientation, refers to assumptions about how to change personal behavior. Approximately 180 subjects ranging from college freshmen to graduate students took the Approaches to Behavior Change (ABC) Inventory. Results supported the notion that change orientation is a concept that may discriminate between various groups of individuals. Some definite patterns emerged among the levels of academic attainment represented by the student subjects. In addition, high and low self-managers showed modest differences in their patterns and substantial differences in their completion of tasks. The ABC Inventory instrument is included in the document along with tables and figures that illustrate the research results. (JAC)
