The psychometric properties of an instrument designed to assess study behaviors of college and university students were examined. A convenience sample of 1052 undergraduates at a group of midwestern colleges and universities and at a four-year college in a United States Caribbean territory responded to the Study Behavior Inventory (SBI), Form D. A series of factor analyses using the principal components model with iteration and varimax rotations yielded three factors composed of items which appear to deal with feelings of competence, preparation for daily routine academic tasks, and preparation for special academic tasks (e.g., term papers and examinations). Internal consistency reliability estimates for the entire instrument and the items in each of the three factors ranged from .70 to .88. The findings indicated that the SBI is a valid and reliable instrument for assessing study behaviors. It is suggested that providers of developmental education and other study skills program should consider including a strong counseling component in their offerings and that it may be useful to view study behaviors as consisting of two sets of activities directed toward short term, routine goals and toward long range, specific goals, respectively.
