摘要：The study aimed to examine students' plagiarism behavior and analyze the impacts of factors on students’ plagiarism behavior at some universities in Vietnam. Specifically, it explores the effects of three factors: subjective norms, attitude, and perceived behavioral control on behavior by two medium factors: intention and justification. This study uses the TPB as a fundamental theory to which justification variable is added to develop a research model. SEM analysis is applied to a sample of 845 students of 6 universities to test the model's validation and hypotheses. The results show that measures are reliable and valid. Most of the hypotheses are supported by collected data. Therefore, this study has significant academic and practical contributions..
