Background: Nurses working in the intensive care units (ICU) regarding the work-index-nursing work environment, the effect level ICU environment has on the nurses' care behaviors and stress levels of the nurses should be determined.
Objective: The study aimed to investigate the effect of the nurse manpower on care behaviours and stress level of the nurses working in the ICU.
Methods: This was a cross-sectional and correlational study. The sample of the study consisted of 123 nurses working in the ICUs. The data were collected using the survey form, Distress Thermometer (DT), The Practice Work Environment Scale of the Nursing Work Index (PES-NWI), and Caring Behaviors Scale-24 (CBS-24).
Results: The mean age of nurses in the ICU was 30.2±5.6 and the mean of working time in the intensive care unit of nurses in the ICU was 3.7±3.1 years. The mean of the DT was 4.8±3.4, and the mean score of PES-NWI was 2.6±1.0 and the mean score of CBS-24 was 4.7±1.1 in nurses in the ICU. The regression model which was studied to investigate the relationship between caring behaviors and stress and nurse manpower of nurses working in intensive care unit was significant.
Conclusion: Care behaviors and stress levels of nurses working in intensive care units are negatively affected by insufficient nurse manpower.
