Abstract

As a transmissible infectious disease, severe acute respiratory syndrome (SARS) was successfully contained globally by instituting widespread quarantine measures. Although these measures were successful in terminating the outbreak in all areas of the world, the adverse effects of quarantine have not previously been determined in a systematic manner. In this hypothesis-generating study supported by a convenience sample drawn in close temporal proximity to the period of quarantine, we examined the psychological effects of quarantine on persons in Toronto, Canada. The 129 quarantined persons who responded to a Web-based survey exhibited a high prevalence of psychological distress. Symptoms of posttraumatic stress disorder (PTSD) and depression were observed in 28.9% and 31.2% of respondents, respectively. Longer durations of quarantine were associated with an increased prevalence of PTSD symptoms. Acquaintance with or direct exposure to someone with a diagnosis of SARS was also associated with PTSD and depressive symptoms.

  • Social distancing was previously proven to trigger negative mental health consequences, including intensified anxiety and depression.

    “Moreover, social distancing was previously proven to trigger negative mental health consequences, including intensified anxiety and depression38,39.”

    From Mindfulness-based online intervention increases well-being and decreases stress after Covid-19 lockdown (2022) · cites this paper as [38]

    The Discussion reports that quarantine can result in psychological distress, including depressive symptoms, and the Results describe anxiety among some respondents. But this study of people quarantined during SARS does not prove that social distancing generally causes increased anxiety and depression; the authors describe their findings as hypotheses requiring further exploration. (LLM, conf=0.88)

  • Social distancing has been proven to trigger negative mental health consequences, including intensified anxiety and depression and/or apathy and hypersensitivity, and can exacerbate mental illness.

    “social distancing has been proven to trigger negative mental health consequences, including intensified anxiety and depression [9,10] and/or apathy and hypersensitivity; it is especially worrisome that it can also exacerbate mental illness [11,12].”

    From Examining the associations between psychological flexibility, mindfulness, psychosomatic functioning, and anxiety during the covid-19 pandemic: A path analysis (2020) · cites this paper as [9]

    The Discussion (page unavailable) reports PTSD and depressive symptoms among people quarantined during the Toronto SARS outbreak; the Results also describe anxiety associated with quarantine measures. The study does not prove that social distancing causes these outcomes, and it does not establish apathy, hypersensitivity, or exacerbation of pre-existing mental illness. (LLM, conf=0.87)

    Experimental — accuracy not yet measured
  • During the SARS, Ebola and MERS epidemics, higher levels of psychopathology were reported, especially in anxiety and stress-related disorders.

    “During the Severe Acute Respiratory Syndrome (SARS) epidemic in early 2000, to Ebola and the Middle East Respiratory Syndrome (MERS), in which quarantine was one of the essential public health measures to break the transmission, higher levels of psychopathology were also reported, especially in anxiety and stress-related disorders [65,66,67].”

    From Relationships between psychopathology, psychological process variables, and sociodemographic variables and comparison of quarantined and non-quarantined groups of malaysian university students in the covid-19 pandemic (2021) · cites this paper as [65]

    The Results (Psychological Impact of Quarantine) report PTSD and depressive symptoms among people quarantined during SARS, and the Discussion identifies PTSD as an anxiety disorder. The paper does not address Ebola or MERS, so it supports the SARS portion of the cited statement, not the claim across all three epidemics. (LLM, conf=0.86)

    Experimental — accuracy not yet measured
  • Previous reports have documented high levels of anxiety and depression among SARS survivors (35%), quarantined individuals (31%), and nurses (38.5%).

    “This is in agreement with previous reports which have also documented high levels of anxiety, depression amongst survivors of SARS (35%) [35], quarantined individuals (31%) [36], and nurses (38.5%) [34].”
  • Studies of the SARS epidemic found that people who had to quarantine had more symptoms of depression and post-traumatic stress disorder.

    “These findings echo those from studies of previous epidemics such as the epidemic of severe acute respiratory syndrome (SARS), during which individuals who had to quarantine experienced increases in symptoms of depression and post-traumatic stress disorder.6, 7, 8, 9”

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.
