Abstract

This study empirically examined the impact of sleep quantity and sleep quality on academic dishonesty as a kind of unethical behavior with a sample of 237 millennials in a Korean university. Sleep quantity was calculated by subtracting bedtime, sleep latency, and wake after sleep onset (WASO) from wake-up time. Sleep quality was measured with the Insomnia Scale developed by Jenkins et al. (1988), and all items are reverse coded. Plagiarism and attitudes toward academic dishonesty (ATAD) were selected as unethical behaviors of millennials at the university. The results of this study are as follows: (1) sleep quantity and sleep quality have negative relationships with ego depletion; (2) ego depletion has no significant relationship with plagiarism or ATAD; (3) sleep quantity has no relationship with plagiarism or ATAD; (4) sleep quality has negative relationships with plagiarism and ATAD; (5) all four indirect effects of sleep quantity and sleep quality on plagiarism and ATAD through ego depletion are not significant. Based on the results, theoretical and practical implications are discussed, and the limitations of this study and recommendations for future research are provided.
