2. Literature Review
Ever since the declaration of COVID-19 as a global pandemic by the World Health Organization on March 11, 2020, the world has placed an immense emphasis on containing the virus's spread (Abelson, 2020). COVID-19 is notorious for its rapid transmission from person to person, with the added concern that asymptomatic individuals can also transmit the virus to others (Adams & Walls, 2020). In an effort to curtail community transmission, numerous countries across the globe implemented unprecedented restrictions throughout March, April, and May 2020. These measures mandated their populations to remain in isolation at their homes and maintain physical distance from others, often termed as "quarantine" or "social distancing." These actions had a profound and far-reaching impact on the daily lives of people. It's worth noting that similar isolation measures were put in place during previous outbreaks like SARS in 2003 and MERS in 2012, which affected regions in Asia and Canada.
Enforcing temporary confinement measures at home to curb the rapid spread of infection has had a noteworthy adverse effect on mental well-being over the medium to long term (Afifi, Cox, & Enns, 2006). Investigations centered on the repercussions of quarantine measures indicate that the elevated levels of stress and anxiety experienced during the quarantine period have the potential to escalate into severe distress, possibly leading to significant psychological conditions (Brooks et al., 2020). Initial research into the COVID-19 pandemic also suggests the emergence of mental health challenges (Torales, O’Higgins, Castaldelli-Maia, & Ventriglio, 2020). However, the majority of these studies have been concentrated among healthcare workers on the frontlines (Anand, Karade, Sen, & Gupta, 2020). Only a handful of studies conducted so far have delved into the psychological consequences for the general population. For instance, (Qiu et al., 2020) carried out a study on psychological symptoms within the Chinese general population (n = 1211) during the early phases of the COVID-19 pandemic. Their findings revealed a high prevalence of stress, anxiety, and depressive symptoms during the outbreak, with as many as 53.8% of their participants reporting the psychological impact of the pandemic as moderate to severe.
Similarly, a research effort conducted by (Organization & others, 2020) unveiled elevated rates of depression and anxiety indicators within the general populace (n = 1642) during the most stringent confinement measures. This inquiry revealed that being female, aged under 50, a university student, or unemployed were factors linked to experiencing COVID-19-related symptoms of depression and anxiety. Thus, existing research underscores the prevalence of these psychological responses in specific regions globally during the initial phases of the COVID-19 pandemic (Wang, Horby, Hayden, & Gao, 2020).
However, it's worth noting that the literature addressing the mental health consequences of the pandemic remains somewhat limited and primarily focuses on particular countries, potentially failing to represent the experiences of diverse populations worldwide. Furthermore, the precise factors related to the COVID-19 pandemic and the subsequent social restrictions that contribute to these mental health symptoms remain largely unknown. Consequently, the current study set out to explore the impact of the pandemic and the subsequent social restrictions on depression and anxiety indicators within the global adult population. In particular, this research examined demographic risk factors, exposure to COVID-19, levels of government-imposed quarantine or isolation measures, and the life changes brought about by COVID-19 as potential predictors of mental health outcomes (Wang, Horby, Hayden, & Gao, 2020).
The COVID-19 pandemic has ushered in significant alterations to individuals' daily routines, exerting a profound impact on their mental well-being. The imposition of measures such as isolation and social distancing, coupled with the overall fallout from the pandemic, has resulted in the loss of crucial social support systems and a sense of normalcy. This has rendered coping with the pandemic-induced stress a formidable challenge. In this context, governments play a pivotal role in assuaging uncertainty among their populations by disseminating reliable information and extending assistance. Furthermore, it is imperative for governments to incorporate mental health interventions into their emergency plans during pandemics (Moriguchi et al., 2020).
The findings of this study underscore the paramount importance of ensuring the accessibility and affordability of mental health treatment on a global scale. Telepsychology services, having been widely embraced during the COVID-19 pandemic, have emerged as one of the primary avenues for addressing the elevated rates of depression and anxiety symptoms. Psychologists should continue to explore and advocate for both videoconferencing- and telephone-based psychotherapy services, particularly during acute phases of the pandemic. Governmental policies that facilitate full reimbursement to mental health care providers for telehealth services play a pivotal role in supporting these endeavors (Nicola, 2020).
Psychologists delivering these services should assess the pandemic's impact on their patients' mental health and offer problem-solving therapy to address the identified challenges. Additionally, employing evidence-based approaches to alleviate subsequent depression and anxiety symptoms is crucial (Afifi, Cox, & Enns, 2006). Encouraging social interactions while adhering to physical distancing guidelines and recommending effective anxiety-reduction strategies, such as relaxation techniques, exercise, and maintaining good sleep hygiene, may help ameliorate the negative effects of the pandemic. Furthermore, assisting patients in optimizing remote work settings, establishing routines, and reorganizing household roles are essential to help individuals cope with the disruptions to everyday life and regain a sense of control that may have been eroded during the pandemic. As exemplified by this current study, the services provided by psychologists play an indispensable role in meeting the mental health needs of the global population (Banerjee, 2020).
While COVID-19, a novel strain of coronaviruses, is known to manifest a spectrum of illnesses ranging from mild cold-like symptoms to more severe conditions such as SARS and MERS (Wang et al., 2020), common symptoms include fever, chills, cough, sore throat, muscle pain, nausea, vomiting, and diarrhea. Men with pre-existing health conditions face a heightened risk of infection and may experience more severe outcomes (Moriguchi et al., 2020). Severe cases can lead to heart and respiratory failure, acute respiratory syndrome, and, in some instances, even fatalities (Moghanibashi-Mansourieh, 2020).
Beyond its physical impacts, COVID-19 can exert significant effects on individuals' mental health (Ahmed et al., 2020). Throughout the pandemic, a gamut of psychological outcomes has been observed, spanning from the individual level to the community, national, and international levels. On an individual level, people may grapple with fears of contracting the virus or perishing, a sense of helplessness, and the stigma attached to their circumstances (Bai et al., 2020). The pandemic has had a detrimental impact on public mental health, potentially culminating in psychological crises (Chew et al., 2020). The early identification of individuals experiencing psychological distress is pivotal for the implementation of more effective intervention strategies. Health crises like the COVID-19 pandemic engender psychological shifts not only among healthcare workers but also within the general populace. These shifts may manifest as fear, anxiety, depression, or feelings of insecurity (Draper et al., 2022). The pandemic's psychological repercussions extend beyond physical health considerations and necessitate comprehensive approaches aimed at addressing the mental well-being of individuals and communities.
Nervousness and anxiety have profound societal implications as well. Recent evidence indicates that individuals subjected to isolation and quarantine encounter elevated levels of anxiety, anger, confusion, and stress (Gao et al., 2020). Across various studies examining psychological disorders during the COVID-19 pandemic, affected individuals have exhibited a multitude of mental trauma symptoms, including emotional distress, depression, stress, mood swings, irritability, insomnia, attention deficit hyperactivity disorder, post-traumatic stress, and anger (Kępińska et al., 2020). Furthermore, excessive exposure to media coverage has been shown to induce distress. However, accurately predicting the psychological and emotional consequences of COVID-19 in the current situation is a formidable task. Studies conducted in China, the first country impacted by the recent virus outbreak, suggest that people's fear of the unknown nature of the virus can precipitate mental disorders (Usher, Bhullar, Durkin, Gyamfi, & Jackson, 2020). The uncertainty shrouding the pandemic and the constant deluge of information can exacerbate anxiety and distress in individuals, underscoring the imperative need for effective mental health support and interventions during these challenging times.
In December of 2019, an unusual outbreak of pneumonia cases surfaced in Wuhan, China, later identified as Coronavirus Disease 2019 (COVID-19) by the World Health Organization (WHO) on February 11, 2020 (Adams & Walls, 2020). The responsible virus, SARS-CoV-2, was recognized as a novel strain of coronaviruses, sharing 79% genetic similarity with the SARS-CoV virus responsible for the 2003 SARS outbreak. On March 11, 2020, the WHO declared COVID-19 a global pandemic. The rapidly evolving situation has left a profound impact on various facets of life, including the global economy, both public and private. The outbreak has led to significant declines in industries such as tourism, aviation, agriculture, and finance. Governments worldwide have implemented restrictions affecting both the supply and demand aspects of economies (Nicola, 2020).
The uncertainties and apprehensions surrounding the viral outbreak, coupled with widespread lockdowns and economic downturns, have raised concerns regarding an upsurge in suicide rates and associated mental health disorders. For example, studies have projected an increase in suicides linked to joblessness, with projections suggesting Canadian suicide cases could rise from 418 to 2114 (McIntyre & Lee, 2020). Similar trends have been reported in the USA, Pakistan, India, France, Germany, and Italy. Moreover, research has indicated a rise in psychological distress among the general population, individuals with pre-existing mental conditions, and healthcare workers (Wang, Horby, Hayden, & Gao, 2020).
Given these findings, there is a pressing need to prioritize public mental health and implement policies to support individuals during this challenging period. Addressing mental health concerns, particularly during a global crisis like the COVID-19 pandemic, is crucial for safeguarding the well-being and resilience of communities worldwide (Li, Bai, & Hashikawa, 2020). Previous experiences with respiratory viral diseases have revealed both immediate and enduring psychological consequences in survivors (Li et al., 2020). Coronaviruses, a group of RNA viruses, can lead to a spectrum of infections ranging from mild common colds to severe acute respiratory syndromes (Mazza et al., 2020). There is evidence suggesting that exposure to coronaviruses during and after outbreaks of Severe Acute Respiratory Syndrome (SARS) and Middle East Respiratory Syndrome (MERS) has been associated with neuropsychiatric disorders (Moriguchi et al., 2020). Survivors of SARS have reported psychiatric symptoms, including post-traumatic stress disorder (PTSD), depression, panic disorder, and obsessive-compulsive disorder (OCD), in follow-up periods spanning from 1 to 50 months. Additionally, seropositivity for coronaviruses has been linked to suicide and psychosis, persisting even one year after SARS (Moghanibashi-Mansourieh, 2020).
The recent global spread of the Severe Acute Respiratory Syndrome Coronavirus (COVID-19) pandemic is also under scrutiny for potential psychiatric implications (Moriguchi & others, 2020). Initial data suggests that patients with COVID-19 may experience symptoms such as delirium, depression, anxiety, and insomnia (Zhou et al., 2020). Coronaviruses have the potential to cause psychopathological consequences either through direct viral infection of the central nervous system (CNS) or indirectly via an immune response (Tan et al., 2020). A range of studies encompassing clinical, post-mortem, animal, in vitro, and cell culture research has indicated that coronaviruses may possess neurotropic properties and can inflict damage on neurons (Presti et al., 2020). Besides the possibility of viral infiltration into the brain, the "cytokine storm" triggered by the immune response to coronaviruses could contribute to psychiatric symptoms by inciting neuroinflammation (Qian et al., 2020).
Contemporary understanding of inflammation within the field of psychiatry suggests that disturbances in the immune system induced by infections could specifically contribute to psychopathology, compounding the psychological stress of enduring a potentially life-threatening disease and its associated inflammation (Rubin & Wessely, 2020). Research has illuminated the interaction between the innate and adaptive immune systems and neurotransmitters in mood disorders, psychosis, and anxiety disorders (Salari et al., 2020). In light of these immunological mechanisms, patients dealing with COVID-19 confront substantial psychological stressors, including the fear of illness, uncertainty about the future, stigma, traumatic memories of severe illness, and social isolation (Shigemura, Ursano, Morganstein, Kurosawa, & Benedek, 2020). These stressors may converge and contribute to the development of psychopathological outcomes. Considering the limited preliminary research on COVID-19 and the evidence from previous outbreaks like SARS and MERS, it is hypothesized that survivors of COVID-19 are likely to exhibit a high prevalence of emerging psychiatric conditions, including mood disorders, anxiety disorders, PTSD, and insomnia. Available data indicates that confusion and delirium are common during the acute phase of the illness, but there is currently no data available on psychopathology during the post-illness phase (Bai et al., 2020). Therefore, the present study aims to explore the psychopathological impact of COVID-19 on survivors after one month of recovery while considering potential influences from various risk factors.
Coronaviruses represent a group of single-stranded RNA viruses, encompassing various subtypes that affect humans. Most of these subtypes typically cause mild upper respiratory tract infections in individuals with healthy immune systems, such as HCoV-229E, HCoV-OC43, HCoV-NL63, and HCoV-HKU1 strains. However, certain coronaviruses have been detected in the brain and cerebrospinal fluid of individuals suffering from conditions like seizures, encephalitis, and encephalomyelitis. Over the years, novel coronavirus strains have sparked outbreaks, such as Severe Acute Respiratory Syndrome (SARS) in 2002 and Middle East Respiratory Syndrome (MERS) in 2012. On December 31, 2019, the World Health Organization (WHO) was alerted to atypical pneumonia cases in Wuhan, China, caused by a new coronavirus known as Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2) (Salari et al., 2020).
As the COVID-19 pandemic has continued to spread, there has been growing awareness of its potential psychiatric implications. The causes of these consequences are multifaceted and closely tied to the broader societal impact and governmental responses to the pandemic, including measures like physical distancing and quarantine. Both individuals infected with the virus and those who are not may experience psychiatric effects due to various factors, including widespread anxiety, social isolation, stress among healthcare and essential workers, and economic hardship, such as unemployment or financial struggles (Solomou & Constantinidou, 2020).
Additional experiences specific to individuals infected with the virus may involve concerns about the severity of their illness, the stigma they may face, and grappling with amnesia or traumatic memories associated with their condition. Neuropsychiatric consequences, referring to mental disorders resulting from brain damage or disease, can occur either directly due to the virus infecting the central nervous system (CNS) or indirectly through an immune response or medical treatment. A case series from Wuhan reported that 36% of patients hospitalized for SARS-CoV-2 infection exhibited neurological symptoms. While these symptoms were mainly mild, such as dizziness and headaches, some patients experienced acute cerebrovascular disease or impaired consciousness as part of their illness (Wang, Horby, Hayden, & Gao, 2020).
Infectious disease outbreaks like COVID-19 can have a psychological impact on both healthcare workers and the general population. A well-documented example is the psychological aftermath observed during the Severe Acute Respiratory Syndrome (SARS) outbreak in 2003 (Shigemura, Ursano, Morganstein, Kurosawa, & Benedek, 2020). Studies conducted during the SARS outbreak revealed that healthcare workers experienced acute stress reactions.
Psychologists, psychiatrists, and behavioral scientists across the globe are grappling with significant challenges related to stress, anxiety, and depression. Depression, classified by the World Health Organization, stands as one of the most prevalent mental disorders worldwide, characterized by symptoms such as low mood, loss of interest, guilt, worthlessness, disruptions in sleep and appetite, decreased energy, and diminished concentration. Both depression and anxiety rank among the most common psychiatric disorders, affecting approximately 10 to 20% of the general population. Stress is an inherent component of human existence and a prevalent issue in modern societies (Sigdel et al., 2020). Anxiety, often accompanied by feelings of fear and unease, presents with symptoms including fatigue, restlessness, and palpitations. Its etiology involves a myriad of factors, encompassing genetic, hereditary, environmental, psychological, social, and biological elements. Individuals grappling with persistent anxiety and worry may experience a decline in self-confidence, leading to feelings of humiliation and, ultimately, contributing to workplace stress and diminished performance (Moghanibashi-Mansourieh, 2020). This cycle can intensify anxiety, leading to the erosion of mental and physical capabilities and potentially culminating in unstable neuropsychiatric disorders over time.
8. Discussions
The COVID-19 pandemic, declared by the World Health Organization as a global crisis, has necessitated the implementation of various measures to curb its spread. These measures, including quarantine and social distancing, have significantly impacted people's lives worldwide. Previous outbreaks of similar nature, such as SARS and MERS, have shown that such isolation measures can have adverse effects on mental health in the mid-to-long term. Studies have indicated that stress, anxiety, and depressive symptoms can escalate during quarantine periods, potentially leading to severe psychological disorders. Early research on the COVID-19 pandemic has also suggested emerging mental health issues, with studies focusing mainly on frontline healthcare workers. However, only a few studies have addressed the psychological consequences for the general public. Research on the Chinese population during the initial stage of the pandemic revealed a high prevalence of stress, anxiety, and depressive symptoms. Similarly, studies during the strictest confinement restrictions showed high rates of depression and anxiety symptoms among the general population.
The psychological impact of the pandemic extends beyond the physical health aspects, resulting in fear, anxiety, depression, and feelings of insecurity among individuals. The uncertainty surrounding the virus, coupled with constant media coverage, exacerbates psychological distress. Additionally, fear of the unknown nature of the virus can lead to mental disorders.
The interaction between the innate and adaptive immune systems and neurotransmitters plays a role in mood disorders, psychosis, and anxiety disorders, adding to the psychological stress of enduring a potentially life-threatening disease and its associated inflammation. To address the mental health challenges during the COVID-19 pandemic, it is essential for governments to provide reliable information and assistance, integrate mental health interventions into emergency plans, and make mental health treatment accessible and affordable on a global scale. Telepsychology services, such as videoconferencing and telephone-based psychotherapy, have been widely adopted and should continue to be promoted, especially during acute waves of the pandemic.
Psychologists should assess the pandemic's impact on their patients' mental health, offer problem-solving therapy, and employ evidence-based approaches to alleviate depression and anxiety symptoms. Encouraging social interactions while maintaining physical distance and recommending anxiety-reducing strategies can help minimize the negative effects of the pandemic. Assisting individuals in optimizing remote work settings, establishing routines, and reorganizing roles at home are also vital for coping with the changes brought on by the pandemic.
In conclusion, the COVID-19 pandemic has not only posed physical health risks but also significant mental health challenges. The global population faces increased stress, anxiety, and depression, making it crucial for mental health support and interventions to be prioritized during these trying times. Addressing mental health needs is essential for building resilience and ensuring the well-being of individuals and communities worldwide. The COVID-19 pandemic has had far-reaching consequences beyond its physical health impact, with significant effects on individuals' mental well-being. Studies have shown a high prevalence of stress, anxiety, and depressive symptoms during quarantine periods, and the uncertainty surrounding the virus has contributed to psychological distress among the general population. The interaction between the immune system and neurotransmitters plays a role in psychiatric disorders, further adding to the psychological stress of facing a potentially life-threatening disease. As governments respond to the pandemic, it is crucial for them to prioritize mental health interventions, provide reliable information and support, and make mental health treatment accessible to all. o address the mental health challenges arising from the COVID-19 pandemic, governments should integrate mental health interventions into their emergency plans and ensure adequate access to mental health services. Telepsychology services, such as videoconferencing and telephone-based therapy, should be widely promoted, especially during acute waves of the pandemic. Psychologists and healthcare professionals should assess the impact of the pandemic on their patients' mental health and offer evidence-based interventions to alleviate depression and anxiety symptoms. Encouraging social interactions while maintaining physical distance and recommending anxiety-reducing strategies can help individuals cope with the effects of the pandemic. Furthermore, assisting individuals in optimizing remote work settings, establishing routines, and reorganizing roles at home can promote a sense of control and stability during this challenging time. By prioritizing mental health support and interventions, societies can better build resilience and ensure the well-being of their populations throughout the global crisis.
