Abstract
BACKGROUND:
Medical students who are prone to psychological stress due to their overburdened curriculum, are at an increased risk of getting adversely affected by the pandemic. The present study was planned to assess the anxiety level among undergraduate medical students across the country using generalized anxiety disorder scale (GAD-7).
MATERIALS AND METHODS:
In this online survey, anonymous data was collected through Google forms from undergraduate students from all the phases of MBBS course across the country from August 15, 2020, to October 15, 2020. Section I collected various demographic information, section II included GAD-7 questionnaire for assessing anxiety and section III had open- ended questions about their impending fear, uncertainties, and apprehensions. The data was expressed in percentage and association among the variables was determined using Chi-square test. Thematic analysis of the open-ended responses was done.
RESULTS:
Among the sample of 1208 students, 81% were from urban areas. During the pandemic, 77% were residing with their parents and 71% parents having stable jobs. Eighty percent students had no relative diagnosed with COVID-19, whereas 52% students had family members with comorbidity. The GAP score showed mild, moderate, and severe anxiety in 27, 24, and 16% students, respectively. Anxiety was significantly associated with rural setting and with COVID-19 positive or comorbid family member (P < 0.05). Open ended responses revealed that majority of the students were finding it difficult to cope with the academic stress at home but still did not want to join back.
CONCLUSION:
With such a high incidence of anxiety among medical students, it is pertinent to safeguard the mental health and implement efficient approaches to upkeep the scholastic, physical, emotional, and professional well-being of medical students during such vulnerable times.
Keywords: Anxiety, COVID-19, generalized anxiety disorder-7, medical students, psychological stress
Introduction
The rampant spread of novel coronavirus (COVID-19) all over India. The outbreak of COVID-19 pandemic prompted the Indian government to impose lockdown all over country. Except some essential services, all facilities including academic institutions were closed sine die till further order.[1] The high infectivity and fatality rates associated with COVID-19 triggered universal psychosocial effects. Disruptions to the daily routine made people feel anxious and unsafe, which needed special attention.[2,3] It has been found that students of pursuing professional training are prone to psychological stress, anxiety, and depression.[4] The medical students reportedly have the highest rates of burnout, anxiety, distress, and depression, even in the absence of pandemic.[5]
The pandemic per se and in addition uncertainty about re-opening of the medical colleges/institutions, resumption of onsite teaching activities also affected the mental status of medical students adversely. Approaching examinations added to the existing confusion and agony. An increase in the rate of suicide among general public and students due to mental instability was an alarming situation caused by this pandemic.[6,7] The generalized anxiety disorder-7 (GAD-7) scale is easy-to-use self-administered questionnaire being used as a screening tool and severity measure for GAD.[8] The GAD-7 is a 7-item questionnaire that is found to be 70%–90% sensitive and 80%–90% specific across various anxiety disorders.[9] Keeping in mind the increased psychological effects of the pandemic on students, the current study was planned to assess the anxiety level among undergraduate medical students using GAD-7.
Materials and Methods
Study design and setting
Cross-sectional study in the form of Online survey from 15th August 2020 to 15st October 2020 across the Indian subcontinent.
Study participants and sampling
Undergraduate students from all the phases of MBBS course across the country. The method followed for sampling was snowball type of convenient sampling method.
Inclusion criteria
Undergraduate medical student who gave consent and were residents of India.
Exclusion criteria
Medical undergraduate students with history of any psychiatric illness.
Data collection tool and technique
As part of the study, an anonymous online survey was conducted through Google form (Google LLC, Mountain View, CA). The link of the survey was shared through WhatsApp (Facebook, Inc., Menlo Park, CA) and e-mails. At the beginning of the form, a section on informed consent where the respondent was given the option to opt out of the survey at any time was given. The purpose of the survey was outlined; the voluntary nature of participation and the anonymity of the survey were also mentioned. This anonymous method of survey collection was chosen to encourage student participation. The survey responses were collected online and made available to the authors in a non-identifiable form.
The survey had three sections
Section I collected the demographic information like their gender, medical college location, setting (urban/rural), the source of family income (salaried/business), and information about any family member/relative diagnosed with COVID-19 and history of comorbidity among family members. The students were also inquired about the history of any psychiatric illness.
Section II had a prevalidated 7-item questionnaire, the GAD scale, GAD-7, in which scores of 0, 1, 2, and 3 is given to categories of “not at all,” “several days,” “more than half the days,” and “nearly every day,” respectively, for each item. Total score is calculated by adding together the scores for the seven questions. GAD-7 scale is a 7-item anxiety scale used for rapid screening for the presence of a clinically significant anxiety disorder, especially in outpatient settings.[8,10] However diagnosis of GAD should not be made based on GAD-7 scores alone.
The final score ranges from 0 to 21, which could be classified as:
0–4 - Minimal Anxiety; 5–9 - Mild Anxiety; 10–14 - Moderate Anxiety; 15–21 - Severe Anxiety.
A score of 10 or greater indicates that further evaluation is required.
Section III included some open- ended questions enquiring about their impending fear, uncertainties about their classes and examinations and apprehension of joining after opening of institution.
Data analysis
The quantitative and qualitative analysis of the data was carried out. Quantitative analysis was done using Microsoft excel software and GraphPad Prism 5 (GraphPad Software Inc., San Diego, CA, USA). Data were expressed in percentage. Univariate analysis between anxiety and other characteristics was done using Chi-square test. For the qualitative analysis, the responses to the open-ended questions were reviewed, and thematically analyzed by two of the investigators (BB, RV). The findings were clustered according to the chosen themes and codes were identified.
Ethical consideration
The study was conducted after obtaining ethical clearance from the Institutional Ethics Medical Committee (GIMS/IEC/HR/EFR/2020/04).

Through open ended questions, the students were asked about their apprehensions and uncertainties on joining back their respective institute/college after lockdown is over. Based on their responses, three themes were identified – fear and worry related to COVID-19 (COVID-19 scare), uncertainties about the classes/examinations and lack of clinical exposure and no apprehensions. Table 5 shows the theme, core ideas and some of the excerpts from the responses to open ended questions.

Discussion
Numerous studies have highlighted psychological effects of COVID-19[11,12] but little literature is available on its psychological impact on medical students. However, anxiety and other psychological effects are very much expected among medical students due to the prevailing circumstances and by the policies executed to restrain the spread of the disease. Additionally, the stress of medical education makes them more prone to develop anxiety disorders, particularly during early phase of medical school.[2,13] It has also been observed that pandemics like severe acute respiratory syndrome severe acute respiratory syndrome, Ebola etc., have invariably affected the physical and mental wellbeing of students.[14] The current study was planned to investigate the anxiety level among medical students, taking into consideration, the explicit sources of anxiety perceived by these students during the crisis. In the current study, we observed anxiety in 67% of medical students, with 27% showing mild, 24% moderate and 16% severe signs of anxiety. The possible reasons for such a high prevalence of anxiety could be changes in their daily routines and lifestyles, lockdown restraints, educational interruptions and the disease itself.[14] Lack of interpersonal communications with friend and relatives could also be a cause of increased anxiety.[15] In general, the medical students have exhibited to be the most distressed group of students, leading to serious consequences like depression and anxiety.[16,17,18,19]
Similar to this study, other researchers also reported increased anxiety amongmedical students due to COVID-19 pandemic. Around one-fourths and half ofthe students reported anxiety as per the surveys by Cao et al., and Saddik et al., 2020, respectively.[20,21,22] In a recently published survey, stress was reported in 72% of medical students.[23] However, in other non-university students, anxiety was found to be much low. According to Chinna et al., 2021, moderate to severe anxiety was reported only in 19% Indian students.[24]
In the current study, we investigated the association of anxiety levels of medical students with their place of residence, source of parental income, and cohabitation with the parents. Association with existing comorbidity and COVID-19 positive cases in family members was also studied. The analysis of our result suggested that anxiety level is strongly association with the place of residence, history of comorbidity among family members and COVID-19 positive cases in the family.
The students living in rural areasweresignificantly more anxiousthan students living in urban areas. Poor Internet connectivity and less-availability of learning resource could be the factors influencing the anxiety level in students residing in rural areas. Additionally lack of better health care facilities and poor hygienic conditions may also contribute to the cause of anxiety.[22] Similar to our findings, Cao et al., 2020 also observed significant association between anxiety and place of residence in college students.[20]
As per the findings of this study, the source of family income and cohabitation with parents had no significant effects on anxiety levels of the students. This is contrary to the report by Cao et al., which showed significant association between the two.[20] It is believed that the stabilityof family income and living with parents has positive impact on students' psychology.[25] However, the result of this study is quite unexpected, as it did not show any significant association between anxiety level and cohabitation with parents and parental income. Availability of social media kept the students connected with their family and friends. The parents might not have expressed and shared their financial problems with their children, to avoid psychological and economic pressure. These could be the possible reasons for non-significant association among these factors and anxiety.
The result of our study showed a significant association between COVID-19 positive family member and anxiety. The high contagiousness of the virus risking others in the family, fear of losing their loved ones and the associated stigma could be the cause of anxiety.[5] Additionally isolation of the infected person and quarantine of contacts could betheindependentrisk factors for anxiety.[14]
Comorbidity in family memberswasalso significantly related to the students' anxiety during this pandemic. Increased mortality in comorbid COVID-19 patientsis a matter of concern for all.[10] Diversion of all medical resources to COVID patients resulted in lack of proper attention to other comorbid non-COVID patients. Patients with chronic comorbid conditions like diabetes mellitus, cardiac diseases, chronic renal failure etc., need regular follow-up in hospital that become problematic and raise the chances of deterioration. All these factors were responsible for anxiety within medical students, as they better understand the consequences.
In response to the open ended question on apprehensions on joining back, some of the students didn't want to go back to their hostel as they felt the conditions prevailing in the hostel may not be favorable to curtail the spread of infection. They were apprehensive about their hostel stay once they return back. Students were worried about getting infected and of spreading the infection to others. Most of the students felt that they are not able to cope with the academic stress as online teaching is not sufficient to cover the syllabus and studying at home is a difficult task. They were worried about their assignments, record books and wanted postponement of the exams. If exams occur, they should be marked leniently. Students want colleges to open for exams and shut down again.” Students in early year of MBBS were concerned about the practical classes; whereas students in late semesters were worried about the lack of clinical exposure. However some students were quite relaxed and were missing their college lives and wanted to go back to their colleges at the earliest.
Strengths and limitations
The study coveredthe undergraduate students from medical colleges located in all the zones of Indian subcontinent; thiswas the strength of the study. Use of validated questionnaire for anxiety made it more reliable. However the study was limited by self reported bias. Only anxiety was measured, we could have measuredother stress related psychological effects and depressionamong the students owing to the pandemic.
Conclusion
In the study, anxiety was reported in 67% of medical students, ranging from mild to moderate intensity. Students residing in rural area reported higher incidence of anxiety as compared to those living in urban area. The anxiety status in medical students was not related to the source of family income and cohabitation with parents. However, having a relative or an acquaintance infected with COVID-19 and comorbidity in any of the family members were independent risk factors for experienced anxiety. The stakeholders must be aware of the psychological stress the medical students are going through during this tough time and safeguard their mental health. It is recommended to implement efficient approaches to upkeep the scholastic, physical, emotional, and professional well being of medical students during such vulnerable times. The students may engage more often in physical exercise; keep themselves busy in activities of their interest and should practice mindfulness and meditation.
