Objective: This study was aimed to determine the effect of privacy consciousness of nursing students on their attitudes towards registration and preservation of personal health data. Method: The study was conducted as a descriptive and correlational research with 255 nursing students. The data were collected by using the Student Information Form, the Registration and Preservation of the Personal Health Data Attitude Scale and the Privacy Consciousness Scale. The data were evaluated in the IBM SPSS Statistics 21.0 program. Mann Whitney U and Kruskall Wallis test were used to analyze the mean scores of the scale in terms of descriptive characteristics. Multiple linear regression analysis was performed to determine the predictor of the Registration and Preservation of the Personal Health Data Attitude scores. Results: The total mean score of the students' the Registration and Preservation of the Personal Health Data Attitude Scale was 4.15±0.43 and the mean total score of the Privacy Consciousness Scale was 4.48±0.48. It was determined that the Registration and Preservation of the Personal Health Data Attitude Scale total score averages of those who received training on the preservation of personal health data were statistically significantly higher than those who did not receive any training (p<0.05). There was a moderately significant positive correlation between the Registration and Preservation of the Personal Health Data Attitude Scale and the Privacy Consciousness Scale total scores (p<0.01). It was determined that the students' Privacy Consciousness Scale scores and status of receiving training on the preservation of personal health data explained 18.9% of the Registration and Preservation of the Personal Health Data Attitude Scale scores. Conclusion: As the privacy level of students increases, their attitudes towards registration and preservation of personal health data are positively affected. The fact that students have positive attitudes towards the protection of patient records and have raised their privacy consciousness is important in terms of the sensitivity of future nurses to patient rights. Improving the privacy perception of nursing students will also be very effective in the process of preserving the personal health data of the individuals they care for. For this reason, it will be important to educate nursing students on privacy and the recording and protection of personal health data throughout their undergraduate education.
