Objective: As a part of their clinical practice curriculum, nursing students are expected to provide sleep hygiene (SH) training to their patients. It is important to determine the factors that affect this training program. We aimed to examine the nursing students' condition of delivering SH training to their patients as well as the relationship between the training program and the students' SH behaviors, knowledge of sleep, and attitude toward the training program. Materials and Methods: A total of 259 nursing students in their second year of bachelor's degree education participated in this study. The data were gathered by using the Individual Identification Form, SH index, Sleep Knowledge Assessment form, and Attitude Towards SH Training form. Results: Based on analysis of the data gathered from the forms, all students reported having received SH training and 80.3% of them admitted to delivering the training to their patients. Logistic regression analysis of the data revealed that SH (Wald chi 2=7.01, p=0.008), knowledge of sleep (Wald chi 2=15.63, p<0.001), and the attitude toward SH training (Wald chi 2=36.29, p<0.001) are important determinants of SH training. Conclusion: The results of this study suggest that better sleep hygiene, enhanced information on sleep, and more positive attitude toward SH training increases the likelihood of successful delivery of SH training to patients.
