Abstract

The COVID-19 (SARS-CoV-2) pandemic constitutes a major health crisis affecting numerous nations, with over 82,994,220 cases and 1,810,360 confirmed deaths reported to date. Such widespread outbreaks are associated with adverse mental health consequences. Hence, it is important to understand the extent and impact of these challenges. In this study, we conducted a Systematic Mapping Study for collecting, cataloguing, and classifying research activities that explore the phycological impact of COVID-19, including anxiety, depression, and stress which seem to be common psychological reactions to the COVID-19 pandemic. Two key research areas were explored as part of our literature review: a) observational studies, reporting on mental health symptoms in particular populations, and b) commentaries and review articles, addressing the psychological impact of COVID-19 on the general population, the healthcare workers, and the high-risk populations. There is the need for a more systematic research approach which could consider associated factors and confounders, such as demographics, sociocultural and health outcomes.

Introduction

In the city of Wuhan, China, in December 2019, a new coronavirus disease –officially named by the World Health Organization as COVID-19 (SARS-CoV-2)— was detected, which soon reached the level of a pandemic and is now affecting the entire world. After 7,834 confirmed cases and 170 deaths from the virus worldwide, the World Health Organization (WHO) declared the outbreak of COVID-19 as an emergency of International public health concern on January 30, 2020. As of 1 January 2021, 82.994.220 confirmed cases and 1.810.360 deaths were recorded due to Covid-19. Following this global health crisis, strict public health measures have been implemented to limit the spread of COVID-19 [1-24].

One of those measures that was implemented globally, was the lockdown [25-27]. The COVID-19 pandemic in combination with the lockdown, however, caused a sense of fear and anxiety in most part of the population, both with short and long-term effects on the psychosocial and mental health of children, adolescents, and adults [28]. Besides, the widespread manifestations of infectious diseases, such as COVID-19, are associated with psychological distress and symptoms of mental illness [3].

According to results of the Collaborative Outcomes study on Health and Functioning during Infection Times (COH-FIT Study) involving 29 countries, there was an increase of 25-33% in negative psychosocial effects worldwide [29-34]. Especially for Greece, 66% of the participants showed a statistically significant increase in levels of stress, loneliness, and anger [7].

It is important that psychiatrists around the world are aware of the associations, manifestations of mental illness with extensive infectious diseases and create or act with appropriate strategies to manage the above, to meet the needs of specific populations [35]. They should also be aware of gaps in existing literature, which may need to be filled in over time through wider clinical experience and research [24].

In the light of the above considerations, the current Systematic Mapping Study was designed to summarize the existing literature that includes research studies focused on mental health issues related to the COVID-19 pandemic.

To sum up, according to Swiss psychiatrist Carl Jung: "Pain itself gives strength for healing [..] and this is the essence of the Greek myth of Asclepius". So, may the right "vein" give strength to all healthcare workers to turn despair into hope [20].

Methodology

Research methodology and selection of bibliography

The research was conducted according to the Systematic Mapping Study standards. A systematic mapping study or scoping study is a process of collecting data and classifying it with the aim of providing an overview of the area or field that requires research [15]. The first step is a detailed literature research, followed by an analysis that allows the results to be classified according to predefined criteria set by researchers [21]. The choice of the systematic mapping study helps to complete the mapping of a field and in the long run will enhance the research work globally. This type of research is mainly used for educational purposes and for the creation of reflections and research hypotheses [14,23].

The PubMed and Google Scholar databases were searched using the search terms "coronavirus", "COVID-19", "Mental Health", "Psychology", "Stress", "Anxiety", "Psychological Impact" in different variants and combinations. In total, 68 studies were retrieved using this method. During the investigation of the above studies, 20 of those were selected.

We included studies that:

• assessed the impact of COVID-19 virus on people’s mental health

• were available in English

• were published in 2020

We excluded studies that:

• only their summary was published, and the full text was not available

• were not written in English

• duplicated previous studies

Results

We included 20 studies, 10 of which were empirical studies and 10 were literature reviews which explored the association between COVID-19 and mental health.

Two main themes were identified and were used to organize this mapping study: (a) observational studies reporting mental health symptoms in specific populations and (b) commentary on the psychological impact of COVID-19 on the general population, healthcare workers, high-risk populations, or vulnerable groups. Observational studies came from different countries and continents. The most prevalent countries were United Kingdom, China, Italy, Spain, Saudi Arabia, Bangladesh, United States of America, Austria, Singapore, and India. The results of the study are displayed in tables 1 and 2.

Discussion

Mental health problems associated with COVID-19

Ten (10) are the observational studies that have been included and report mental health symptoms in specific populations. They demonstrate the strong correlation between COVID-19 pandemic and the inevitable protection measures, which have particularly worrying psychosocial implications. As the below analysis demonstrates, consequences can be strong feelings of loneliness, depression, anxiety, stress, insomnia, post-traumatic stress disorder (PTSS), and more.

More specifically, in an online study by Groarke et al [12], on a sample of 1964 citizens of the United Kingdom, 530 stated that they experience strong feelings of loneliness (27%); the younger ones and the divorcees. More vulnerable to feelings of loneliness, appear to be the youngers (OR: 4,67-5,31), the divorcees (OR: 2,29), those who had depressive characteristics before the pandemic (OR: 1,74), those who experience difficulty in controlling their emotions (OR: 1.04) and those who suffer from poor sleep quality due to the wider COVID-19 crisis (OR: 1.30). On the contrary, levels of loneliness were lower in those people with higher levels of social support (OR: 0.92) and those who were married, cohabiting (OR: 0.35), or lived with a larger number of adults (OR: 0.87).

Many studies positively associate the pandemic with depression and anxiety. Precisely, in a survey of 18,147 participants in Italy, 17.3% showed symptoms of depression, 20.8% anxiety and 21.8% high perceived anxiety. Reasons for the occurrence of these unpleasant feelings and anxiety disorders, among others, were quarantine, discontinuation of work due to COVID-19, death of a relative or loved one. Similar percentages occur in a survey of 7,236 participants, conducted in China, with 35.1% reporting anxiety and 20.1% showing depressive symptoms. Likewise, in Austria, according to Pieh et al [22], in an online survey of 1,005 participants, depressive symptoms (21%) and anxiety symptoms (19%) are higher during COVID-19 compared to previous epidemiological data. Moreover, the pandemic and lockdown of COVID-19 seem particularly stressful for younger adults (<35 years old), women, unemployed or low-income people. In Saudi Arabia, 23.6% of survey participants reported a moderate or severe psychological impact of the epidemic. More specifically, 28.3%, 24% and 22.3% reported moderate to severe symptoms of depression, anxiety, and stress, respectively [2]. Another study that links COVID-19 with severe psychological problems and concerns is that of Rodríguez-Reyet al [25] conducted on 3,055 Spaniards. Participants stated that they considered the current health crisis to be quite serious, and the majority considered the COVID-19 crisis to have a serious impact on their daily lives, including changes in their daily routines and postponement of important activities. Approximately 36% of the participants reported moderate to severe psychological impact, 25% reported slight to severe anxiety levels, 41% reported depressive symptoms, and 41% felt stress. Women, young people, and those who lost their jobs during the health crisis showed more severe psychological symptoms. What seems to worry Spaniards the most is the possibility of an economic crisis caused by the pandemic. The increased need for mental health services due to COVID-19 demonstrates another study involving 565 adult Americans, which found that COVID-19 experiences are associated with a higher chance of being diagnosed with anxiety and depression (ORs ≥ 3.0). Anxiety related to COVID-19 also showed high variability (R2 ≥ 30) in stress, depression, anxiety, and functional-physical impairment, while personal experiences associated with the diagnosis of COVID-19, death of a family member and the stress of having COVID-19 relates to a very high risk of symptomatic emotional disorder.

Lower, but noteworthy, were the rates of anxiety and depression experienced by medical staff and healthcare workers in general who looked after people with COVID-19, on a study conducted in Singapore. Particularly, 14.5% reported experiencing high levels of anxiety, 6.6% stress and 8.9% identified symptoms of depression. Anxiety was higher among healthcare workers than on medical staff (20.7% vs. 10.8%) [29]. Another study focusing on healthcare workers involved in caring for COVID-19 patients was that of Chew et al [6]. The participants were 906 in total, from 5 major hospitals in Singapore and India, and according to self-completed questionnaires 5.3% of respondents showed symptoms of moderate to very severe depression. In this research, significant correlations were found between physical symptoms and psychological effects (including depression, anxiety, and stress). In addition, they experienced a higher frequency of physical symptoms due to emotional distress compared to other Chinese groups, while a large number (32.3%) of respondents reported headaches.

Physical symptoms such as difficulty in breathing, dizziness, headache, and fever were also shown in a high rate of participants in a study conducted in Saudi Arabia by Alkhamees et al [2].

Another negative impact of the COVID-19 pandemic and the protection measures adopted by most countries, is poor quality of sleep and insomnia, moderate or even clinical in some cases [26] with healthcare workers showing higher rates of poor sleep quality compared to other professional groups [13].

Several of the studies show that COVID-19 and quarantine are associated with post-traumatic stress disorder (PTSD) and subsequent symptoms (PTSS) [26,29], whereas, according to Rossi et al [26], there is a positive correlation with adjustment disorder. Finally, in one of the surveys included, the sample showed a percentage of people having thoughts of self-destructive behavior. The study, which was conducted in Bangladesh, involved 10,067 people and besides 33.3% of the participants who showed symptoms of depression, increased rates of suicidal thoughts were observed at 5% of the sample.

Impact of COVID-19 on the mental health of the general population, healthcare workers and vulnerable groups

One study [28] analyzed and presented the effects on the mental health of children and adolescents in areas affected by the COVID-19 pandemic and the imposition of national or regional exclusions which intended to prevent further spread of the infection. The impact of the above on minors is determined by several factors, such as age, educational status, pre-existing mental health problems, financial problems, or quarantine due to infection or fear of infection. The conclusions of this research study show the urgent need to plan long-term development studies and implement a detailed action plan to meet the psychosocial and mental needs of children and adolescents during and after the pandemic. There is a need to improve the access for people of this age group to mental health support services, and furthermore, states - and not only - should be directed towards providing support measures to create health mechanisms to deal with the current crisis. To achieve this innovative policy of supporting the mental health of children and adolescents, there must be both in-person and digital collaboration between psychiatrists, psychologists, pediatricians, and community volunteers [36,37].

Young people, especially Chinese students studying away from their families, are a social group that has been of great concern to researchers. According to Zhai and Du [38] from 12 February 2020, in many countries where Chinese students study, a travel ban to countries with COVID-19 was announced. China’s international students have lived in fear that their families could be at risk of the virus (SARS-CoV-2) without themselves being able to help them. During this time, they experienced discrimination, isolation, and stigmatization, and were even considered potential carriers of the virus. These conditions led them to anxiety and other related disorders. In these cases, close co-operation between local authorities and health workers is essential.

Furthermore, Kontoangelos et al [16] in a study that examined 65 tasks - using the Medline computer database - concluded that children are more likely to experience anxiety, stress, and fear. In addition, the results of the study showed that the elderly are the social group that has been identified as the most vulnerable to COVID-19 and often feel terrified and frightened.

Rafael A. Caparros-Gonzalez and Fiona Alderdice [5], in their study, address the issue of perinatal mental health. Stress associated with events such as pandemics, earthquakes, and famines, may be associated with immediate and long-term mental and physical health consequences for both mother and baby. Slowing down the transmission of a virus during pandemics requires significant behavioral changes, some of which can be detrimental to mental health. For example, a key strategy for slowing down the COVID-19 pandemic is social isolation. However, there is an instinctive need for connection between people [32]. Pregnant women have been identified as vulnerable groups and are among those most concerned about the spread or infection of SARS-CoV-2 [4]. Measures to reduce the virus have led to lower support from relatives and friends, increased financial difficulties and increased domestic violence. It is emphasized that due to the aforementioned concerns, the support of each pregnant woman and questions regarding her mental health in the prenatal and postnatal appointments by her doctor, is of high importance.

At the heart of the pandemic is, of course, the entire medical community. Employees in the specific industry face high levels of work stress even under normal circumstances. The disease and the COVID-19 crisis in general put additional pressure on doctors and the healthcare system, and research [10] shows that such pressure poses a greater risk of psychological stress for doctors. For this reason, authorities and healthcare leaders need to show strong leadership and support the doctors and their families during the COVID-19 pandemic, as well as to make efforts to reduce mental health problems in healthcare workspaces. This can be achieved by adding a "Mental health support process to healthcare staff" even on a daily basis. Likewise, the study of Kontoangelos et al [16] states that medical staff and healthcare workers are under great physical and psychological pressure. Stressors will appear or worsen, while many health workers will be adversely affected psychologically. According to two aforementioned studies [29] medical staff in Singapore and India show relatively high rates of anxiety and depression symptoms.

Another vulnerable group investigated during the pandemic is homeless people. These people live in environments that are conducive to an epidemic disease as they live in places (formal or informal) that may not have access to basic hygiene, which may facilitate the transmission of the virus. These individuals should therefore be considered a vulnerable group, as research shows that even under the age of 65, they are five to ten times more likely to die than the general population. In the age of coronavirus and quarantine, according to Tsai and Wilson [31], the homeless have a strong fear of being inadvertently admitted or even imprisoned, events that may hamper their mental health care.

Of particular interest are two reports from China [36,39] on COVID-19 and patients with pre-existing mental illness. In March, about 50 patients and 30 employees of a psychiatric hospital had been sick and quarantined due to Covid-19. Reasons for this may include overcrowding, lack of medical facilities and psychiatric hospitals, lack of knowledge among mental health professionals and difficulty in ensuring cooperation of patients suffering from psychotic disorders [39]. Patients with pre-existing mental disorders seem to be at greater risk of recurrence or new episodes of the disorder due to the stress associated with COVID-19 [36]. During this pandemic, it is vital that psychiatrists become familiar with virus control procedures and work closely with doctors and public health experts, thus minimizing the risks faced by their patients [39].

Finally, a study examined the potential impact of the COVID-19 pandemic on the general population. The study [37] highlighted the role of unpredictable, uncertain, and serious disease, which often leads to misinformation and social isolation, while contributing to stress and mental morbidity. The authors stressed the need for mental health services, especially for vulnerable groups, as well as the need to generally support society in order to reduce the adverse psychological effects of this pandemic. A study from Japan [27] emphasized on the economic impact of COVID-19 and its effect on human well-being, as well as the possible high levels of fear and panic behaviors on the general population. This study identified some social groups at higher risk for adverse effects on their mental health, including COVID-19 patients and their families, people with mental or physical illness, and health care workers.

Conclusions

The COVID-19 pandemic has affected the mental health of vulnerable groups as well as that of the general population. Psychiatrists and other professionals in the field, provide their services continuously and in a daily basis to patients and people in need. However, while mental health is clearly taken into consideration in multiple levels, research has shown that there is a larger need to support the mental health sector with innovative solutions or with further support to the existing infrastructure.

Although large-scale observational studies are available in this field, to date, the available literature is relatively incomplete. Yet, it still contains numerous and valuable observations and suggestions for all professionals working in the field of mental health, related to psychiatry, to general hospitals or working in community services. As the number of patients affected by this pandemic continues to increase, mental health professionals worldwide are facing a challenge and an experiencing an opportunity. The challenge refers to addressing the numerous obstacles and limitations identified in the literature cited in this manuscript, while, the opportunity relates to at least implementing the existing advice or recommendations wherever possible. An additional significant issue, however, is that understanding and properly managing COVID-19 and its implications, may still take quite a long time. This requires a coordinated effort not only by psychiatrists but by the healthcare system as a whole [19].

Undoubtedly, there is a need for further research, even in the form of preliminary or pilot studies, to assess the extent of this pandemic in other countries, especially in those where mental health infrastructure is less developed and the impact is likely to be more severe [8]. Research should also focus on other vulnerable populations, such as children and adolescents in rural areas who face barriers to accessing healthcare or those from lower socioeconomic backgrounds. Finally, there is a need to develop mental health interventions that can be taught to healthcare workers and volunteers.
