Occupational stress and burnout are widely encountered among many healthcare professionals, including nurses and doctors, as well as among members of other professions. For example, nurses, who have disrupted circadian rhythms, are seen to have sleep problems. In addition, their personality traits are also considered to be related with burnout. This study aimed to identify nurses' circadian preference and personality traits along with their effects on sleep quality and their relationship with burnout. In this study, 211 nurses (40 male, 171 female) using the correlational model from quantitative research methods was used since the variables of morningness/eveningness, personality trait, sleep quality, and burnout were aimed to be investigated at once, without intervention, within the predictivity context of the relationship among them. When the scores obtained from the burnout scale were examined, it was observed that the emotional exhaustion and personal accomplishment subdimensions were so close to the median value and mean, while depersonalization was quite low compared to these sub-dimensions. The participants' sleep quality was seen to be at the lowest step of the poor sleep quality class. When the scores obtained from the MESSI scale are examined, it is seen that the scores obtained from the morning affect dimension are above the median value, and the highest average according to the Five-Factor Personality Traits Scale is obtained in the subdimensions of agreeableness and conscientiousness. Female gender, constantly work at night, having a high number of weekly working hours increased burnout level. Additionally Evening chronotype, poor sleep quality, neuroticism, agreeableness, extroversion and conscientiousness personality traits were found to be associated with burnout in this study. In the study, being of different chronotypes, having other personality traits, and varying sleep quality scores were seen to affect the sub-dimensions of burnout.

This study carried out to examine the effects of nursing care given to coronary intensive care patients according to their circadian rhythms on sleep quality, pain, anxiety, and delirium. This study was designed as a randomised controlled, clinical investigation. The study population consisted of patients treated in the coronary care unit of a training and research hospital between September 2022 and February 2023. Total of 44 participants were included. The included participants were followed up for 3 days in the coronary intensive care unit. Data were collected using “Patient Information Form, Sleep Quality Scale in Coronary Intensive Care Patients (SQ-CC), Visual Analogue Scale (VAS), Morningness-Eveningness Questionnaire (MEQ), Hospital Anxiety and Depression Scale (HADS), Intensive Care Delirium Screening Checklist (ICDSC).” In addition, melatonin and cortisol measurements were made, and sleep data were taken with a smartwatch. Patients with intermediate chronotype, delirium, on ventilator support, or using sedative drugs were excluded. The chronotypes of the participants were determined, and the patients in the intervention group were given nursing care by their circadian rhythms. No intervention was made to the control group, and their routine care was continued in accordance with intensive care unit functioning. Frequency distribution, dependent and independent sample t-test, Wilcoxon test, repeated measures analysis of variance, Mann Whitney U, and chi-square analysis were used to evaluate the data. The study has been registered in ClinicalTrials.gov (Identifiers: NCT04934436). During statistical analysis, the groups were coded as Group A and Group B, ensuring blinding for the statistician. The intervention group’s sleep quality increased compared to the control group (post-test SQ-CC total scores: intervention group 22.41 ± 6.67 vs. control group 50.45 ± 10.63, p < 0.001). Although no significant difference was found between the groups as a result of the study, there was a significant decrease in the pain score in the intervention group (VAS pre-test: 1.55 ± 2.15, post-test: 0.68 ± 2.21, p = 0.036). The anxiety of the intervention group decreased significantly compared to the control group (post-test HADS-Anxiety scores: intervention group 3.18 ± 3.29 vs. control group 8.50 ± 5.66, p = 0.001). The post-test delirium score was higher in the control group compared to the intervention group (post-test ICDSC scores: intervention group 0.32 ± 0.48 vs. control group 1.18 ± 0.50, p < 0.001). Melatonin increased and cortisol decreased in both groups without statistically significant differences between them (melatonin and cortisol levels: p > 0.05). Considering the sound levels in the environment, the first-night decibel mean was significantly higher in the intervention group than in the control group (first-night decibel mean: intervention group 56.58 ± 2.43 dB vs. control group 54.51 ± 2.41 dB, p < 0.05). Finally, the smartwatch data show no significant difference in sleep times between groups (p < 0.05), but the intervention group had more deep and total sleep, while the control group had less deep sleep. Nursing care given in accordance with the circadian rhythm increases sleep quality and reduces the risk of delirium and anxiety in patients followed up with acute coronary syndrome in the coronary intensive care unit. What is known about the topic: •The intensive care environment and the patient’s current disease negatively affect the individual’s sleep, and the sleep quality of the patient decreases. •Poor sleep quality in the intensive care units leads to an increased delirium, anxiety and perception of pain. What this paper adds: •In environments where multiple patients are treated, such as intensive care, determining the circadian rhythms of the patients and providing care at appropriate times reduces the anxiety of the patients, reduces the delirium score. •Maintaining the patient’s biological rhythm and providing care in accordance with the rhythm in crowded patient environments significantly improves sleep quality. Relevance to Clinical Practice and/or Recommendations for Further Research: •In line with the results obtained from this study, it is recommended that nurses working in intensive care should determine the circadian rhythms of the patients in order to reduce the frequency of occurrence of comorbid conditions and provide nursing care in accordance with the circadian rhythms of the patients at appropriate hours. •Circadian rhythm, the importance of which has been increasingly understood recently, causes positive/negative effects on human health in many areas, from sleep to cancer. For this reason, it is recommended for nurse researchers to work on developing a nursing care model based on circadian rhythm and to test it on chronic pain type. •In addition, since there is no clarity about melatonin and cortisol levels in the literature, it can be said that studies with large samples and meta-analyses are needed to observe significant differences on this issue. •On the other hand, it is recommended that melatonin and cortisol levels in serum or urine should be measured frequently in future studies.

Excessive or abusive use of smartphones, which is related to personality traits, has led to the emergence of phubbing, which is becoming a very widespread problem. Excessive use of smartphones also affects sleep patterns. In this context, the concept of chronotype, which is closely related to sleep, becomes prominent. Therefore, the present study aims to examine the relationship between chronotypes, personality traits, and phubbing levels of students studying in the field of health. 732 students participated in the study, which was planned using a correlational research design. Data were collected using a demographic form, the phubbing scale, the big five personality traits scale, and the composite scale of morningness (CSM). Descriptive statistical analyses, Pearson correlation analysis, and multiple linear regression analysis were used in the analysis of the data. As a result, Agreeableness, Conscientiousness, Neuroticism, and Morningness/Eveningness were significant predictors of phubbing. Other variables, on the other hand, were not found to be significant predictors of phubbing. Among the student participants in the study the phubbing level was high for those who were evening- and neither chronotype, who were not agreeable and conscientious, and who had neurotic personality traits.
