The Psychological Status and Self-Efficacy of Nurses During COVID-19 Outbreak: A Cross-Sectional Survey.

A novel coronavirus pneumonia broke out and gradually developed into a global public health problem. Health care workers, especially nurses, suffered from great occupational pressure and psychological distress during the outbreak of infectious diseases. We performed a cross-sectional survey to investigate the psychological status and self-efficacy of nurses in public hospital during COVID-19 outbreak between 16th and 25th February 2020. A total of 223 nurses participated in this study. The prevalence of anxiety and depression symptoms was 40.8% (CI 95%: 34.4%-47.2%) and 26.4% (CI 95%: 20.6%-42.2%), respectively. There was no difference in the prevalence of anxiety symptoms among demographic variables. There was significant differences in the prevalence of depression symptoms according to professional titles (P = .020). The mean score of self-efficacy was 25.90 ± 7.55. The self-efficacy was negatively correlated with anxiety (r = -0.161, P < .05). The psychological status of nurses in public hospital during COVID-19 outbreak needs our attention. Improving nurses' self-efficacy in dealing with emerging infectious diseases may be helpful to their psychology.

Introduction

In December 2019, a novel coronavirus pneumonia case was reported in Wuhan, China, and then the novel coronavirus (COVID-19) broke out in China rapidly and spread to other countries. The novel coronavirus pneumonia soon attracted international concern and was listed as a public health emergencies by WHO.[1] The novel coronavirus pneumonia was confirmed to be a human-to-human disease, and the main source of transmission was symptomatic diagnosed patients.[2] Moreover, it was reported that asymptomatic carriers may also transfer the COVID-19 to others.[3] On February 25th, 78064 confirmed cases and 2715 deaths cases have been reported in mainland China.[4] As a result, the general public were likely to be stressed anxious and depressed during the outbreak and at the peak of the COVID-19 epidemic.[5,6] During the outbreak of COVID-19, medical staff in public hospital, especially nurses, provide health service for patients as usual. The patients they contact may be those being in incubation period, waiting to be diagnosed, or asymptomatic carriers. They are exposed to many known and unknown risk factors. As of February 11th, 3019 medical staff were infected with COVID-19 in mainland China, resulting in 5 death.[7] Coping with infectious diseases, the medical staff were under great occupational pressure and experienced psychological distress.[6] Little is known about psychological status of nurses during COVID-19 outbreak.

Health care workers suffered from great stress and psychological distress during the epidemic of infectious diseases. For example, health care workers reported disease related concern and suffered from somatic symptoms and psychological distress during SARS attack.[7,8] Middle East respiratory syndrome coronavirus caused worry, fear and PTSD-like symptoms among hospital workers.[9,10] A significant proportion of health care workers experienced worry and anxiety about influenza pandemic.[11]

Due to reduced accessibility to psychological support, less first-hand medical information, less intensive training on personal protective equipment and infection control measures during COVID-19 pandemic, health care workers were more likely to experience stress and psychological distress.[8] A multinational, multicentre study showed that out of 906 health care workers who participated in the survey during COVID-19 pandemic suffered from expansive range of physical symptoms, 5.3% was moderate to very-severe depression, and 8.7% was moderate to extremely-severe anxiety.[9] These psychological distress caused by acute infectious diseases may persist for a long time and even lead to posttraumatic stress disorder.[10,11] Compared with other hospital staff, nurses had a high proportion of psychological distress.[12] What’s more, a study found that non-frontline nurses who worked in hospitals were more likely to suffer from psychological problems than front-line nurses.[13] Therefore, we intended to investigate the psychological status of these nurses.

Self-efficacy reflects a belief and a sense of confidence in whether individuals can use their capacity to achieve tasks.[14] The self-efficacy is related to the level of motivation, actions, and psychological state.[15] Schwarzer raised the concept of general self-efficacy, which referring to an individual’s overall self-confidence in dealing with challenges of different environments contexts or burgeoning issues.[16] It can reflect individual’s behavior and psychological status in different contexts. The self-efficacy of nurses correlated with mental health, resilience, and job burnout.[17-19] Studies found there was a negative correlation between general self-efficacy and anxiety.[20,21] During the outbreak of SARS, health care workers with low self-efficacy experienced higher fear.[22] In addition, self-efficacy was a important factor in predicting nurses’ willingness to care for patients with emerging infectious disease.[23,24] This study was to examine the psychological status and self-efficacy of nurses still working in public hospital during COVID-19 outbreak, and explore the relationships among demographic variables, anxiety, depression, and self-efficacy.

Methods

Study Design and Data Collection

This study was a descriptive cross-sectional survey. The participants were from one of public tertiary hospitals in Xiamen, Fujian Province. This hospital is not responsible for the treatment of COVID-19, but it also admits fever and suspected patients. Once the patients are confirmed to be infected with COVID-19, they will be sent to another government designated hospital for treatment. Respondents was limited to registered nurses still working in the hospital during the outbreak of COVID-19. We searched the departments admitting patients as usual in the hospital’s electronic medical record system. Then we explained the survey to the head nurses of each department and obtain their consent. We sent recruitment and the internet questionnaire to the head nurses every day, and they helped us to transmit questionnaires to nurses. Nurses choose whether to participate in the survey according to their own willingness. When no one participated in the survey for 3 days, we terminated the questionnaire. The survey was granted by the medical ethics committee of hospital (xmzsyyky Ethics No. 2020-006). Data were collected between 16th and 25th February 2020, and a total of 223 nurses participated in the study.

Measures

Demographic characteristics

The nurses’ demographic characteristics in this study include gender, age, education level, professional titles, working experience, department, living status, the history of contact with confirmed, suspected or fever patient.

Psychological status

The Generalized Anxiety Disorder-7 (GAD-7)

Spitzer developed a 7-item self-report instrument based on the DSM-IV criteria for screening generalized anxiety disorder.[25] It asked participants how often they were bothered by some typical anxiety symptoms during the last 2 weeks. Each item is scored from 0 to 3. When the total score is more than 5 points, it indicates that respondents may experience anxiety symptoms. GAD-7 had good reliability and validity in Chinese population.[26]

The Chinese Version of the Patient Health Questionnaire (PHQ-9)

The PHQ-9 was developed by Kroenke et al based on the DSM-IV criteria, and it was to assess the severity of depression.[27] The PHQ-9 consists of 9 items, with a total score ranging from 0 to 27. Respondents whose score is over 5 points may have different degrees of depression symptoms or even depression disorder. This scale is brief and convenient, and it has excellent internal consistency reliability and test-retest reliability. The Cronbach’s α of the Chinese version of PHQ-9 in the general population was 0.86, test-retest reliability coefficient was 0.86.[28]

Self-efficacy

We used the Chinese Version of the General Self-Efficacy Scale to measure the confidence and belief of nurses when facing to COVID-19. The scale includes 10 items, ranging from 1 to 4. The higher scores indicate having greater confidence and self-efficacy in coping challenges and stress. The Cronbach’s α coefficient, test-retest reliability coefficient, and split-half reliability were 0.87, 0.83 and 0.82, respectively.[29]

Data Analysis

All the data were analyzed using SPSS22.0. Demographic information, and scores of anxiety, depression, and self-efficacy were described by number (n), percentage (%), mean and standard deviation. The relationship between anxiety, depression, and demographic variables were examined by chi-square test or Fisher exact tests. To explore the relationship between anxiety, depression, and self-efficacy, we used Pearson correlation analysis.

Results

A total of 361 nurses from 11 departments met our inclusion exclusion criteria, and finally 231 nurses participated in the study. The response rate was 61.8%. The majority of the participants were female (97.3%), between 26 and 45 years old (71.7%), and had baccalaureate degree. Almost half of the nurses had primary professional titles and less than 10 years of working experience. Fifty-nine nurses contacted with confirmed or suspected patients during outbreak, and 67.7% of nurses contacted with fever patients. Other demographic information is shown in Table 1.

The mean score of GAD-7 was 4.31 ± 4.52, and PHQ-9 was 3.24 ± 4.04 (Table 3). Table 2 shows the prevalence of anxiety and depression among nurses. The prevalence of anxiety and depression symptoms was 40.8% (CI 95%: 34.4%-47.2%) and 26.4% (CI 95%: 20.6%-42.2%), respectively. Ninety one nurses experienced different degree of anxiety whose GAD-7 scores were more than 5 points, including 64 mild anxiety, 19 moderate anxiety and 8 severe anxiety. A total of 59 nurses had depressive symptoms, and the proportion of mild, moderate, severe, and extremely severe depression was 74.6%, 18.6%, 5.1%, and 1.7%. There was no difference in the prevalence of anxiety symptoms in demographic variables. There was significant differences in the prevalence of depression symptoms according to professional titles (P = .020) (see Table 1).

Discussion

This survey was to investigate psychological status and self-efficacy of nurses in public hospital, still caring for patients during COVID-19 outbreak. We found the prevalence of anxiety and depression symptoms among nurses was 40.8% and 26.4%, respectively, which was higher than other similar studies on health care workers and non-healthcare workers.[8,9] Possible explanation may be that China was the first country facing a large-scale outbreak of COVID-19, health care workers suffered from great physical and psychological stress. According to other study, it was reported nurses in one of designated hospital were under great psychological stress and experienced psychological symptoms, such as compulsion, anxiety, fear, etc.[30] We found the prevalence of anxiety symptoms among nurses was 40.8%, and depression was 26.4%. Although this hospital is not government designated hospital, the results indicate that nurses have high levels of anxiety and depression. This hospital it admits fever patients and patients waiting to be diagnosed. Nurses in this hospital are also at high risk of exposure to the virus. Unlike nurses in designated hospital who are certain about the patients’ diagnoses and wear a full set of protective equipments, they may have come across newly admitted patients without signs and symptoms to indicate whether they had infected COVID-19 and they may not have taken effective protective measures. In our study, the incidence of moderate and severe anxiety was 12.1%, and depression was 6.7%, which was lower than reported general population.[5] Similarly, a study found that the general public had higher level of vicarious traumatization than the front-line nurses.[13] This may be related to the prolonged lockdown affecting daily life and poor disease knowledge.[6,13] These results imply that nurses in this type of hospital have great psychological distress during outbreak. It suggests that managers should pay attention to nurses’ psychological status and provide support to relieve their anxiety and depression.

In this study, nurses with intermediate professional titles have higher prevalence of depression symptoms. A possible explanation is that nurses with intermediate titles are well-experienced. They are an important part of the battle of epidemic prevention and control, and they can evaluate the risk of infection according to clinical experience. As a result, they may have greater psychological distress. We also found that there was no difference in the prevalence of anxiety symptoms among demographic variables. It may be that anxiety symptoms are widespread among nurses during COVID-19 outbreak. It needs to be further verified.

The mean score of self-efficacy was 25.90 ± 7.55, which was lower than previous studies.[31,32] Possible reasons may be due to the fact that COVID-19 is a novel coronavirus and causes an outbreak in a short time. Nurses lack experience and confidence to cope with it. The results demonstrated that self-efficacy was negatively correlated with anxiety (r = −0.161, P < .05), which was consistent with previous studies.[33] Nurses who were not confident in coping with the COVID-19 may feel more anxious. COVID-19 is a new coronavirus, and it causes a rapid outbreak of disease. Medical staff need to learn the knowledge of novel coronavirus pneumonia and adjust therapeutic plan continuously. Some nurses feel their knowledge is insufficient, which makes nurses feel incompetent and results in negative psychological experience.[34] This can provide a reference for the training of nurses’ emergency ability in the future. Different from previous studies, there was no significant correlation between self-efficacy and depression.[33] This may be due to the difference in population and situations.

In order to better respond to outbreaks and avoid psychological crisis on population, the Chinese government has taken a series of psychological assistance intervention, including releasing guiding principles for psychological intervention during COVID-19, publishing psychological guidelines books, creating psychological assistance hotlines, and providing online psychological counseling.[35] However, according to guidelines issued by the central health authority, the first targets of psychological intervention are confirmed patients, frontline health professionals and administrative staff.[36] This study found the nurse in this hospital had high incidence of anxiety and depression, and there was no significant difference in the incidence of anxiety and depression among departments and whether exposed to confirmed patients or not. These indicated that the psychological status of nurses who worked in non designed hospital or who didn’t contact with confirmed patients during outbreak also needs attention and support. Online psychological self-help intervention system,[37] like online cognitive behavioral therapy and mindfulness-based interventions, may be helpful to promote nurses’ mental health. Cognitive behavioral therapy may challenge cognitive bias when they overestimate the risk of contracting and suffering from COVID-19, and enhance confidence in the ability to take care of patients.[6,38] Mindfulness-based interventions is aimed at reducing stress through mindfulness meditation practices.[39] They have demonstrated efficacy in reducing depression and anxiety symptoms among university students during the epidemic of COVID-19.[40]

There were some limitations in this study. First, we only sent recruitment to nurses in 1 hospital, so this study failed to compare the differences among hospitals and groups of people, such as doctors, technician, administrative staff, etc. Thus, the findings should be further confirmed in different hospital and different health care workers. Second, this research lasted for 10 days, and a total of 223 nurses took part in it ultimately. Response bias may exist and sample size may affect data analysis results. Sample size needs to be expanded in the future. Third, this study was a cross-sectional survey, lacking follow-up, and the questionnaires were self-report. There were likely to lead to recall and reporting bias. Moreover, we couldn’t distinguish if the anxiety or depression was caused by the COVID-19 or preexisting, and lacked follow-up care for nurses who had severe anxiety or depression.

In conclusion, our results show that nurses in non government designated hospital have great prevalence of anxiety and depression symptoms during COVID-19 outbreak. Nurses’ professional titles are related to depression. Nurses with intermediate professional titles experience more depression symptoms. The self-efficacy coping to COVID-19 was negatively correlated with anxiety.
