Prior research on plagiarism has indicated that men may have a greater predisposition toward academic dishonesty than women. However, little research has been conducted using psychometrically tested instruments to validate such claims. To address this gap, a survey was conducted with 377 undergraduate students at a Canadian university on their attitudes toward plagiarism using a psychometrically validated instrument (the Attitudes Toward Plagiarism Questionnaire - Revised). Using differential item functioning/Rasch analysis, no overall differences in attitudes toward plagiarism based on gender were found. A descriptive analysis of both men and women revealed that while only a concerning minority of students reported engaging in plagiarist behaviours; there was a tendency for students to take a permissive stance on plagiarism. These results are discussed within the wider context of plagiarism research in higher education.
