  Abstract 


OBJECTIVE: This study investigated the psychological effect of the coronavirus disease 2019 (COVID-19) outbreak on medical students in China.
METHODS: In February 2020, an online survey was performed using a WeChat app with an online survey program to collect and analyze the effects of the COVID-19 outbreak on the mental health of medical students across China.
RESULTS: Overall, 757 medical students responded to the survey. About 2.24% reported middle and high levels of anxiety since the COVID-19 outbreak began, and 14.40% reported middle and high levels of depression. Bachelor's students and those whose residence registration was located in a rural area were more likely to have anxiety and depression, compared with postgraduates and students whose residence registration location was an urban area, respectively.
CONCLUSIONS: The COVID-19 epidemic is associated with a low but real rate of psychological trauma in the medical students of China, and protective programs are needed to lessen this adverse effect.

  Introduction Top


Since December 2019, the outbreak of coronavirus disease 2019 (COVID-19) in Wuhan, China has attracted worldwide attention. As of March 2, 2020, there were 80,174 confirmed cases of COVID-19 nationwide. The outbreak has caused unpredictable stress. The disease poses a great threat to people's life and safety, and this has brought psychological pressure on the residents of the affected areas and the entire country. In the face of large-scale infections of the public, medical staffs around the world have actively performed medical assistance that reflects their professional spirit.[1] In normal times, medical personnel suffer daily high mental stress, and during epidemics the risk of psychological distress is often higher than that of the public.[2],[3],[4],[5] Medical students generally have heavy academic burdens, and at the time of the outbreak many were already in teaching hospitals beginning internship rotation and participating in clinical practice.

This survey sought understanding of the presence and degree of anxiety and depression of medical students during this unusual time of disease outbreak, and provides a scientific basis for psychological crisis intervention.


  Methods Top


Research design

This psychological questionnaire was a cross-sectional survey, open to all provinces of Mainland China. Each participant who filled out the questionnaire was effectively a volunteer. The research design, implementation, and evaluation were conducted by Professor Gu Yongquan's team at China National Clinical Center for Geriatric Disorders (Xuanwu Hospital Capital Medical University).

Study object

All the enrolled medical students were in Mainland China. Subgroup analyses were by education (undergraduate and postgraduate), gender, and region of residence (urban and rural).

Method and observe index

Each participant was required to provide demographic data including age, gender, place of residence, income, marital status, and education level. The survey tools for assessing psychological distress were the internationally recognized self-rating anxiety scale (SAS) and the Self-Rating Depression Scale (SDS).[6],[7] SDS standard scores ≥50 were considered to reflect depressive symptoms, and scores of 50–59, 60–69, and ≥70 were defined as mild, moderate, and severe depression, respectively. SAS scores revealed levels of anxiety, and scores of 50–59, 60–69, and ≥70 were adjudged mild, moderate, and severe.

Data collection and statistical methods

All the collected data were processed by SPSS (20.0) software. The SAS and SDS scales were each analyzed to determine mean ± standard deviation. The means of the two groups were compared using the t-test, and the subgroup analyses were performed using the Mann-Whitney U test.

General information

Overall, there were 757 valid survey questionnaires collected, from 245 men (32.3%) and 512 women [67.6%; [Table 1]. Of them, 558 (73.71%) were 20-to-30 years old; and 698 (92.21%), 58 (7.66%), and 1 (0.13%) were unmarried, married, and divorced, respectively. The urban and rural populations were represented by 474 (62.62%) and 283 (37.38%) students.

Among the total study population of 757 students [Table 1], 425 (56.14%) were undergraduates; and among the 332 postgraduates, there were 278 and 54 in masters and doctoral programs, respectively, i.e., 36.72% and 7.13% of the total population. In addition, the study population comprised 126 scientific research graduates (37.55%), and 206 professional graduates (62.05%).

The source area covered all provinces in Mainland China [Table 2]. The top five regions were: Henan (358, 47.29%); Shanghai (52, 6.86%); Beijing (51, 6.73%); Shandong (30, 3.96%); and Hebei (27, 3.56%).

Among all the subjects, 576 (76.09%) acknowledged feeling anxiety and panic during the epidemic, while 181 (23.91%) never experiencing anxiety [Table 3]. The main factors leading to anxiety and panic included: Aggravation of the epidemic (463; 67.69%); lack of personal protective equipment (420, 61.40%), and reports by the media (263, 38.45%). Many participants (425, 62.13%) recognized they had no suitable method to solve their psychological distress, and so must endure or solve this on their own. A large majority (608, 80.32%) of participants believed that psychological interventions were necessary. Most participants (427, 56.41%) believed that psychological interventions should have been available during the initial outbreak to alleviate psychological distress.

The overall score of this study population for anxiety based on the SAS was 30.64 ± 7.71, which was significantly higher than the normal in China [29.78 ± 10.07, n = 1158; T anxiety = 3.07, P = 0.002; [Table 4].[8] The overall SDS score for depressive symptoms in the present population was 42.06 ± 12.33, which is statistically comparable with the general population (41.88 ± 10.57, n = 1340, t depression = 0.418, P = 0.676).[8]

Subgroup analysis

The overall research sample of 757 students was divided into three sub-groups for analysis by education (undergraduate and graduate), gender, and residence area (urban and rural).

Undergraduate compared with graduate students

The median SDS score in the undergraduate group was 40, and the median SDS score in graduates was 39; the Mann-Whitney U test showed that the difference in SDS scores between the two groups was statistically significant [U = 64122.5, Z =–2.155, P = 0.031; [Table 5].
Table 5: Self-rating depression scale and self-rating anxiety scale scores of undergraduates and postgraduates, n (%)

The median SAS score for undergraduates was 38, and the median SAS score for graduates was 35; the Mann-Whitney U test showed that the difference in SAS scores between the two groups was statistically significant [U = 62399.5, Z =–2.735, P = 0.006; [Table 5]. Thus, undergraduates had both higher SDS and higher SAS scores than did graduate students.

Men compared with women

The median SDS score in men was 39, and the median SDS score in women was 40 [Table 6]. The Mann-Whitney U test showed that there was no significant difference in SDS score between the two groups (U = 62317.5, Z =–0.143, P = 0.886).
Table 6: Self-rating depression scale and self-rating anxiety scale scores of men and women*

The median SAS score in men was 38, and the median SAS score in women was 36 [Table 6]. The Mann-Whitney U test showed that there was no significant difference in SAS score between the genders (U = 58230, Z =–1.598, P = 0.110). There were no significant differences in SAS scores between men and women.

Comparison between students in residential towns and rural areas

The median SDS score in the urban group was 39, and the median SDS score in the rural group was 40 [Table 7]. The Mann-Whitney U test showed that there was a statistically significant difference in SDS scores between the two groups (U = 60481.5, Z =–2.266, P = 0.023). That is, the SDS score of the urban population was lower than that of the rural population.

However, the median SAS scores in both the rural and urban groups were 36, and the Mann–Whitney U-test results show that there was no significant difference in SAS scores between the two groups [U = 66147.5, Z = −0.318, P = 0.751; [Table 7].


  Discussion Top


Mental support has been offered in medical school in China in recent years. Considering that medical education is in itself a stressful process, a previous study reported that local medical students showed elevated levels of depression, anxiety, and stress, and which differed by year or stage of education. Specifically, the levels of depression, anxiety, and stress were relatively low in the 1st year, but students in both the third and 5th year experienced considerable levels of these negative psychological states.[9] Students' mental health may affect their academic attainment, social life, and the quality of service they provide to the community as future doctors. Furthermore, their own mental distress may influence the way they perceive mental health and pursuit of help in the care of their future patients.[10]

The severe acute respiratory syndrome (SARS) outbreak occurred in China in 2003, and a large number of medical staff responded to this health crisis emergency. Wong et al.[11] reported a cross-sectional questionnaire study that investigated perceived stress and psychological responses to the SARS outbreak in healthcare students, at the height of the outbreak in Hong Kong in 2003. All the groups reported high levels of perceived stress. In the context of the current new coronavirus pneumonia epidemic, medical students also are at high risk of psychological problems. Mass psychogenic illness can be difficult to differentiate from bioterrorism, rapidly spreading infection, or acute exposure to toxic substances. Early recognition and the appropriate response to such incidents can substantially benefit the outcome.[12]

On January 27, 2020, the National Health Commission of China published a national guideline for psychological crisis intervention in response to the heightened spread of COVID-19, the disease caused by SARS coronavirus 2 infection.[13] This publication marks the first time that guidance to provide multifaceted psychological protection of the mental health of medical workers was initiated in China. Studying the psychological situation of medical students in the context of this epidemic is very important to guide subsequent interventions.

The present study found that 76.09% of medical students said they experienced anxiety and panic associated with the COVID-19 epidemic. Indeed, the data showed that the SAS and SDS scores of medical students at this time were higher than normal in China. This indicates that this new coronavirus pneumonia can undermine the psychological state of medical students.

The subgroup analysis found that medical undergraduates had higher levels of psychological distress than did graduate students. This may be related to factors in the Chinese medical training system of undergraduates, including longer duration of studies, higher number of memory learning tasks, and more exams, relative to the work of graduates.

In this study, the men and women medical students were statistically similar with regard to scores for anxiety and depression. These results are in accord with that of Shuo and Zhengtu[14] However, other studies in China found that men had higher rates of anxiety and depression symptoms,[15],[16],[17] putatively because the genders differed in response to new situations and perception of subjective and objective pressures. In addition, the general social role expectation is that men should be more independent than women. Society or families have higher expectations for success of men. Thus, men have raised expectations for their futures, and levels of anxiety and depression are higher.

In the present study, the students in rural areas had a higher depression score compared with that of those in urban areas. This is consistent with Dechun et al.,[18] and may be related to the poorer public health conditions in rural areas and lack of personal protection materials. Thus, socioeconomic, cultural, and environmental factors also affect students, an important factor in mental health. This suggests that mental health support should help students cope with the effects of differences in socioeconomic culture, and help students from rural areas establish self-confidence and self-reliance.

Among the medical students surveyed in the present study, 78 (10.30%) expressed both anxiety and depression. The overlap between these two psychological problems may be due to subjective fear and have motoric dimensions.[19]

This project found that 425 medical students (62.13%) had no outside means of coping with their psychological distress, and could only endure on their own. Of the 757 students overall, 608 (80.32%) thought that they needed psychological intervention, and 536 (76.68%) said they would seek help from a psychologist and use psychological counseling techniques and methods to help solve psychological problems, if available. In addition, 427 (56.41%) of the students responded that psychological intervention should be immediately offered when an epidemic emerges.

There are some limitations in this study. As a nationwide cross-sectional study, the sample size is small. Secondly, for assessing the mental distress of medical staff in response to the new coronavirus pneumonia, a scale should address particular features of this epidemic such as suddenness and lack of treatments. However, only the internationally recognized SDS and SAS scales were available, which are relatively simple with low sensitivity. Thus, the specific psychological pressures faced by medical students were difficult to sample.


  Conclusions Top


Facing this epidemic, medical students reported a higher risk of anxiety. Timely psychological support and intervention is needed while fighting the epidemic, especially for undergraduates and medical students living in rural areas.
