The Theory of Planned Behavior was chosen as the framework, assuming that college students are rational decision makers seeking to maximize economic gains in purchasing compact discs. A questionnaire was given to 450 students from four college campuses in the Kaohsiung area of Taiwan. Analyses showed that the more positively rated the Behavioral Intention toward purchasing pirated music compact discs, the more likely the college students were to purchase them. Conversely, when Subjective Norms and Perceived Behavioral Control were higher, college students were less likely to make a purchase. Therefore, buying pirated compact discs was consistent with the premises for Attitude, Subjective Norms, and Behavioral Control.
