With the proliferation of online graduate enrollment by 35.7% from 2003 to 2014, the literature indicates the number of reported academic integrity cases is on the rise. A quantitative correlational study was used to determine which determinants, if any, had a relationship to the behavioral intent to engage in plagiarism among MBA students enrolled in online programs at two four-year public postsecondary institutions in the southeastern United States. Twenty-two participants completed a 53-item online survey containing closed-ended items soliciting beliefs toward academic dishonesty and demographic data. The Theory of Planned Behavior informed the study design including the variables of interest: behavioral beliefs, normative beliefs, and control beliefs. Additional demographic variables of receiving a formal or informal consequence for plagiarizing, the number of hours worked per week, and the number of dependents were also examined. Spearman's rho and rank-biserial were used to analyze the data. Key findings included statistically significant positive relationships between participants' behavioral beliefs, normative beliefs, and control beliefs, and their behavioral intent to engage in plagiarism. Findings indicated online MBA students' perceptions of situational opportunities to plagiarize could either foster or inhibit future academic integrity behavior. Also, plagiarism may occur based on perceived positive or negative outcomes and the attitudes of friends and peer groups. The findings suggest academic leaders can benefit from greater allocation of resources toward anti-plagiarism initiatives at the class, program, and institutional policy level and use of various forms of communication to ensure online MBA students are well-informed of the institutions' academic integrity policies.
