Materials and Methods
The present study was conducted on nurses working in the reanimation
unit and internal medicine, coronary and neurology intensive care units
at Gazi Yaşargil Training and Research Hospital between January 20, 2020
and March 20, 2020. The sample of the study was selected from nurses
working in intensive care units, independent of all other departments in
the hospital. The day-shift group included nurses working from 08.00 to
16.00, and the night-shift group included nurses working from 16.00
until 08.00 on the next day.
The study included a total of 80 volunteers, including 40 day-shift and
40 night-shift employees, by getting their informed consent and giving
information that they can leave the research at any time. The data of
the five volunteers were excluded due to their declaration of requesting
to leave the study. The study excluded a volunteer because of declaring
the use of benzodiazepine, which is likely to impair executive
functions, after participation in the study and 2 volunteers due to
incomplete completion of the scale. The data of 72 volunteers, 31 in the
day-shift and 41 in the night-shift, were included in the evaluation.
The demographic data of the sample groups were obtained by the
sociodemographic data form prepared by the researchers. The researchers
applied the Hamilton Depression Rating Scale (HAM-D), Hamilton Anxiety
Rating Scale (HAM-A), Pittsburgh Sleep Quality Index (PSQI) and Stroop
color word interaction test (SCWI) in both groups. All tests were
performed at 15:00 in the day-shift group and at 7:00 in the night-shift
group. Thus, tests were applied in both groups one hour before the end
of the shift.
