The current study examined the longitudinal relationships between goal contents and academic cheating (serious versus minor cheating) among representative college students. Based on the framework of goal contents theory within self-determination theory, wealth, fame, affiliation, self-growth, social-concern, and leisure goals were tested as predictive factors of two types of academic cheating. Participants were 2,360 representative college students from the Korean Education Longitudinal Study majoring in business, humanities, social sciences, engineering, education, arts, and medicine. They answered survey questionnaires twice at 1-year intervals. Hierarchical regression analysis found that self-growth negatively predicted serious as well as minor cheating, and the wealth goal was positively correlated with minor cheating after controlling for previous cheating behaviors and gender. The results support goal contents theory and show that classifying academic cheating by severity permits a deeper understanding of students? academic cheating. Educators and practitioners seeking to encourage students? ethical behavior should pay closer attention to the goal contents they pursue to provide appropriate guidelines.
