COVID-19 and mental health: A review of the existing literature

Open access
Rajkumar, Ravi Philip·2020·Asian Journal of Psychiatry

Abstract

The COVID-19 pandemic is a major health crisis affecting several nations, with over 720,000 cases and 33,000 confirmed deaths reported to date. Such widespread outbreaks are associated with adverse mental health consequences. Keeping this in mind, existing literature on the COVID-19 outbreak pertinent to mental health was retrieved via a literature search of the PubMed database. Published articles were classified according to their overall themes and summarized. Preliminary evidence suggests that symptoms of anxiety and depression (16-28%) and self-reported stress (8%) are common psychological reactions to the COVID-19 pandemic, and may be associated with disturbed sleep. A number of individual and structural variables moderate this risk. In planning services for such populations, both the needs of the concerned people and the necessary preventive guidelines must be taken into account. The available literature has emerged from only a few of the affected countries, and may not reflect the experience of persons living in other parts of the world. In conclusion, subsyndromal mental health problems are a common response to the COVID-19 pandemic. There is a need for more representative research from other affected countries, particularly in vulnerable populations.

  • The COVID-19 pandemic has been associated with decreases in positive emotions and quality of life and increases in negative emotions, anxiety, fear, stress, depression, and sleep disturbances.

    “mental health has been characterized by decreases in positive emotions and quality of life [5,6,7,8] as well as increases in negative emotions, anxiety, fear, stress, depression, and sleep disturbances [8,9,10,11,12,13,14].”

    From At the Peak of the Second Wave of COVID-19, Did Millennials Show Different Emotional Responses from Older Adults? (2022) · cites this paper as [12]

    The Results section (Observational studies; page not provided) reports anxiety, depressive symptoms, stress, and an association between anxiety and impaired sleep. The discussion of the general population also describes fear as a likely response. The paper does not report decreases in positive emotions or quality of life, or a general increase in negative emotions. (LLM, conf=0.87)

  • A review of existing literature on COVID-19 and mental health shows an increase in symptoms of depression, anxiety, self-reported stress, fear, and sleep disturbances.

    “According to Rajkumar (2020), a review of the existing literature on COVID-19 and mental health shows an increase in symptoms of depression, anxiety, self-reported stress, fear, and sleep disturbances.”

    From Knowledge of COVID-19 and Its Influence on Mindfulness, Cognitive Emotion Regulation and Psychological Flexibility in the Indian Community (2020) · cites this paper as Rajkumar (2020)

    The Results section’s observational-studies table reports depressive, anxiety, and self-reported stress symptoms, while the accompanying text links anxiety with impaired sleep. The general-population literature section discusses fear as a likely response. These passages do not establish that all five symptoms increased relative to a baseline; the discussion of fear is predictive rather than a measured increase. Page numbers are not provided in our copy. (LLM, conf=0.86)

    Experimental — accuracy not yet measured
  • The awareness that the infectious virus is around and can cause ill-health and fatal outcomes is taxing, leading to sadness and feelings of fear and worry.

    “This might be due to the fact that the awareness that the infectious virus is around and can cause ill-health and fatal outcomes is taxing, thus leading to sadness and feelings of fear and worry (Cao et al., 2020; Li Z. et al., 2020; Rajkumar, 2020; Wang et al., 2020b; Özdin and Bayrak Özdin, 2020).”

    From Knowledge of COVID-19 and Its Influence on Mindfulness, Cognitive Emotion Regulation and Psychological Flexibility in the Indian Community (2020) · cites this paper as Rajkumar, 2020

    The Results section on the general population reports that the seriousness and uncertainty of COVID-19 may contribute to stress and mental morbidity, and describes likely fear and panic. The review also reports anxiety and depressive symptoms, but it does not specifically link awareness of possible illness or death to sadness, fear and worry. (LLM, conf=0.82)

    Experimental — accuracy not yet measured
  • The COVID-19 outbreak is associated with a major mental health burden, increased depressive symptoms, decreased sleep quality, and elevated anxiety in the general population.

    “initial studies indicated a major mental health burden among the public, increased depressive symptoms, decreased sleep quality, and elevated anxiety during the COVID-19 outbreak [3–5].”

    From Efficacy of a web application for stress management among Iranian college students during COVID-19 outbreak: a study protocol for randomized controlled trials (2020) · cites this paper as [5]

    The Results table reports moderate-to-severe depressive symptoms in 16.5% and anxiety symptoms in 28.8% of a Chinese general-population sample, supporting a substantial mental health burden during the outbreak. The observational-studies discussion links anxiety with impaired sleep, but the sleep studies concern medical staff and self-isolating individuals, not the general population as a whole. The cited findings also do not establish increases in symptoms or declines in sleep quality relative to before the outbreak (page numbers unavailable in our copy). (LLM, conf=0.86)

    Experimental — accuracy not yet measured
  • Covid-19 has had a drastic impact on the population's mental health, including medical students.

    “Moreover, Covid-19 has had a drastic impact on the population’s mental health [40–43], including medical students [44–48].”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
