Abstract

Prolonged social isolation is known to cause alterations in conscious experience, such as hallucination, and cognitive problems. Surprisingly, although COVID-19 quarantine policies involved long periods of physical confinement and isolation, little is known as to whether this was associated with alterations in consciousness and cognition. We conducted a comprehensive survey of 300 Chinese participants who were subjected to very strict COVID-19 quarantine while answering the survey. Forty percent of the participants indicated having more cognitive problems and psychotic-like symptoms during quarantine compared to before. These problems varied systematically with quarantine conditions: Fewer face-to-face interactions were associated with increased psychotic symptoms, cognitive problems, and anxiety. Smaller quarantine spaces were associated with increased psychotic symptoms and anxiety. Longer quarantine duration when quarantined outside of home was associated with increased anxiety and decreased positive outcomes. These findings provide novel insights into the impact of quarantine on consciousness, cognition, and the resilience factors that may counteract such disturbances. More broadly, the findings indicate that changes in consciousness and cognition, previously well-documented in other contexts following extended social isolation, also apply to the enforced quarantine during the pandemic.

Home quarantine during COVID-19 blunted childhood trauma-related psychiatric symptoms in Chinese college students
Article
Full-text available
  • May 2023
Background Childhood trauma confers risks to mental health. However, little is known about whether home quarantine (HQ) during the coronavirus disease 2019 (COVID-19) pandemic exaggerated or mitigated the effect of childhood trauma on mental health. Objective To examine the modulating effects of prior childhood traumas on the longitudinal changes of psychiatric symptoms in college students before and after HQ during the pandemic. Methods This was a two-wave longitudinal study on the mental health of 2,887 college students before and after HQ during the COVID-19 pandemic. The relationships between the changes in the Patient Health Questionnaire-9 (PHQ-9), Symptom Checklist-90 (SCL-90), 16-item Prodromal Questionnaire (PQ-16), Childhood Trauma Questionnaire (CTQ), and Social Support Rating Scale (SSRS) scores were analyzed. Results The students with childhood trauma showed a significantly greater decrement in psychiatric symptoms after HQ (F = 17.21, 14.11, 18.87, and 17.42 for PHQ-9, PQ-16 objective and distress, and SCL-90, respectively). The correlation coefficients between the CTQ and these symptoms scales were significant at baseline (r = 0.42, 0.34, 0.37, and 0.39), and decreased after HQ (r = 0.17, 0.20, 0.18, and 0.19). The decrement of depressive, psychotic, and overall symptoms was positively correlated with the scores of the CTQ (r = 0.08–0.27) but negatively correlated with SSRS (r = −0.08−−0.14). Multilinear regression analysis confirmed the results of the CTQ and SSRS regarding the modulation of the dynamic changes in psychiatric symptoms. A constructed structural equation model indicated that the total effects of childhood trauma on decreased psychiatric symptoms were partly mediated by lower baseline social support. Conclusion Home quarantine during the COVID-19 pandemic could blunt the adverse effects of childhood trauma on mental health, especially for prodromal psychotic symptoms in college students. Changes in relative deprivation and social support may be mediating factors.

Article
Full-text available
  • Jul 2022
Objective This study focuses on positive effects of the COVID-19 pandemic and aims to identify associations between gender, individual quarantine and duration of the COVID-19 (short- medium- and long-term pandemic), and posttraumatic growth (PTG). Method The data was collected via an online survey in Israel, and included 1,301 participants, 543 participants experienced short-term pandemics, 428 participants experienced medium-term pandemics and 330 participants experienced long-term pandemics. Most of the participants were female (73.6%), ranging from 18 to 89 years-old. The participants answered questions about their demographic background, individual quarantine experiences and ranked their PTG level. Results The results indicate a significant main effect of gender and pandemic duration (short-, medium- and long-term pandemic). Women reported higher PTG levels than men, and participants experiencing short-term pandemic reported significantly lower PTG levels than participants experiencing medium- or long-term pandemic. There was also a significant interaction between gender and pandemic duration regarding PTG and a significant interaction in PTG by gender, pandemic duration and individual quarantine. Conclusion The discussion addresses the findings in the context of traditional gender roles and gender differences in finding meaning and worth in home confinement situations.

Home-made blues: Residential crowding and mental health in Beijing, China
Article
Full-text available
  • Jul 2022
Although residential crowding has many well-being implications, its connection to mental health is yet to be widely examined. Using survey data from 1613 residents in Beijing, China, we find that living in a crowded place – measured by both square metres per person and persons per bedroom – is significantly associated with a higher risk of depression. We test for the mechanisms of such associations and find that the residential crowding–depression link arises through increased living space-specific stress rather than increased life stress. We also identify the following subgroups that have relatively stronger residential crowding–depression associations: females, those living with children, those not living with parents, and those living in non-market housing units. Our findings show that inequality in living space among urban residents not only is an important social justice issue but also has health implications.

COVID-19 and psychosis, depression, obsession and quality of life in Lebanese patients with schizophrenia: Any changes after 5 months of quarantine?
Article
Full-text available
  • Feb 2022
Background Previous research revealed an absence of any previous studies reporting the impact that pandemics may have on psychotic symptomology, nor on the physical health of people with psychosis in response to the epidemics of the COVID-19. The direction of the impact of the COVID-19 on schizophrenia is unknown, as the risk of infection could vary from patients to patients according to clinical comorbidities, cognitive impairment, acute symptoms, and family support. To the best of our knowledge, no study has provided details on the variation of symptoms in patients with schizophrenia during the quarantine of COVID-19 outbreak. Therefore, the primary objective of the study is to investigate the variation of psychotic symptoms, depression, obsession and quality of life in patients with schizophrenia before and after 5 months of quarantine and evaluate factors associated with these variations during the quarantine period. Methods A cross-sectional study was performed on a sample of 190 chronic patients institutionalized for schizophrenia for more than 1 year at the Psychiatric Hospital of the Cross. The baseline assessment was done in December 2019; the second assessment was done in August 2020 (5 months after the lockdown). Results Getting updates about the coronavirus minimally, some and most of the times were significantly associated with a decrease in positive psychotic and psychopathologic symptoms 5 months after quarantine compared to before it. Practicing religiosity some and all the time versus not was significantly associated with a decrease in negative, psychopathology symptoms and total PANSS score after 5 months of quarantine compared to before it. Finally, female gender (B = 1.77) was significantly associated with an increase in the WHO Domain 3 score (better social relations) after 5 months of quarantine compared to before it. Conclusion Patients with schizophrenia fare better symptomatically after 5 months of quarantine if they receive constant updates about COVID-19 and if they tended to practice religiosity.

Facing the Pandemic and Lockdown: An insight on Mental Health from a longitudinal study using diaries
Article
Full-text available
  • Jan 2021
We conducted a longitudinal online study to examine attenuated psychotic symptoms (APS) over time in a sample of locked-down individuals. We used (i) questionnaires and (ii) the automatic analysis of the emotional content of narratives. Participants ( N = 162) were recruited to complete an online survey 4 times between March and June 2020 (T1, T2, T3, T4). T1 completion coincided with the beginning of the lockdown, and T4 with the pandemic trough. Depression, anxiety, and stress were assessed with the DASS-42 and APS with the PQ-16. Psychosocial data such as the feeling of loneliness and social network size were also collected. The participants wrote daily narratives during the lockdown period. Anxiety and APS were the highest at T1 and decreased over time. APS and APS-associated distress were correlated with the DASS-42 at all times. APS arose acutely at the beginning of the pandemic, despite participants being socio-economically advantaged, and were related with negative emotions.

Sensory Deprivation and Psychiatric Disorders: Association, Assessment and Management Strategies
Article
Full-text available
  • Sep 2021
Background Sensory deprivation (SD) is a widely prevalent condition that leads to various health-related consequences and is also an important cause of disability worldwide. Earlier, SD experiments were used as research modalities to alter human behavior. In recent years, the focus has shifted to understand how SD can affect the mental health of individuals (with congenital or acquired sensory impairments). This narrative review focuses on the current understanding about the association of SD and psychiatric disorders. Methods A comprehensive literature search was done PubMed, Scopus, PsycINFO, and Google Scholar and in the cross-references of relevant articles. Keywords included “sensory deprivation,” “blindness,” “deafness,” “mental illness,” “psychiatric disorders,” “prevalence,” “assessment,” and “management” in various combinations. Only original articles (abstract and full text) published in English till October 2020 were included. Results The prevalence of anxiety, depression, dementia, suicidality, and psychosis in persons with SD is higher than the general population (highest being in persons with dementia with comorbid SD). Several mechanisms/hypotheses have been proposed to explain these associations. Assessment of SD includes a thorough history taking, with adequate awareness about the difficulties faced during a psychiatric interview in this population. Modifications in the psychometric assessment procedures are warranted. Management depends on a multi-disciplinary approach that includes proper referral to specialties, pharmacological management (depending on diagnosis as well as taking care of ototoxic/ocular side-effect profile of the drugs), and nonpharmacological supportive measures. Conclusions SD is a complex condition, and evidence suggests that persons with SD have higher psychiatric morbidity. A comprehensive assessment, along with holistic management approach is warranted.

Changes of psychotic-like experiences and their association with anxiety/ depression among young adolescents before COVID-19 and after the lockdown in China
Article

  • SCHIZOPHR RES
Objective Lockdown policies during COVID-19 pandemic have potential adverse psychological impacts on youth. However, little is known about their influence on the changes of psychotic-like experiences (PLEs) among adolescents, nor about the possible association between changes in PLEs and changes in anxiety/depression symptoms. We investigated these two questions through a longitudinal comparative study. Methods In total, 1825 adolescents were surveyed before COVID-19 and after the lockdown in China (T0, October 20th, 2019 and T1, May 18th, 2020). PLEs, anxiety, and depression were measured with paranoia, anxiety and depression subscales of the Mental Health Inventory of Middle school students (MMHI-60). Within-subjects Wilcoxon test, Spearman correlation test, and Kruskal-Wallis test were adopted. Results Significant increase in adolescent PLEs scores was observed after the lockdown (Wilcoxon's w = 9.302, p < 0.001). We also found positive correlation between changes of PLEs and changes of anxiety/depression (Spearman's rho = 0.59/0.53, both p < 0.001). Furthermore, four PLEs trajectories were identified based on the report of PLEs at two timepoints: 60.4% with no PLEs, 9.3% remitted PLEs, 16.7% new PLEs, and 13.6% persistent PLEs. Significant difference was found in changes of anxiety/depression among four groups (p < 0.001); notably, the group with new-onset PLEs had the greatest exacerbation in anxiety/depression symptoms (both p Bonferroni <0.001). Conclusions This work is the first to identify increases in adolescent PLEs across the COVID-19 pandemic and suggested a close longitudinal association between PLEs and anxiety/depression. Our findings have implications for adolescent mental health crisis interventions during the pandemic.

Article
  • Jun 2021
Purpose The COVID-19 pandemic has challenged leaders to alter the way they manage their organization's employees, such as requiring them to quarantine, self-isolate or practice social distancing so that they comply with government health directives. The purpose of this study is to investigate the impact of the quarantine on the workplace. Design/methodology/approach Structured interviews containing open-ended questions were conducted with fifty Australian public sector executive managers to gauge the effect of the COVID-19 pandemic on their organizations. Findings The study reveals the effects that the virus had on the organizations' teamwork as well as individuals' learning. It finds that organizations experienced both positive effects, such as increased creativity and initiative, and negative effects, such as reduced satisfaction with work teams, from the pandemic. Originality/value This study also adds to the still-developing body of knowledge regarding the effects of the virus on individuals' levels of work team satisfaction as well as a variety of other factors specific to public sector organizations

Self-isolation, Psychotic Symptoms and Cognitive Problems During the COVID-19 Worldwide Outbreak
Article
  • May 2021
  • PSYCHIAT RES
The worldwide outbreak of CoronaVirus Disease appeared in 2019 (COVID-19) has forced millions of people into social isolation. Past research has documented negative psychological effects of self-isolation during health crises, in terms of stress, anger or depressive symptoms, but overall ignored psychotic symptoms and cognitive problems. The present study (n = 211) examined the relationship between the conditions of self-isolation – that is, duration, living space, frequency of social interactions – and psychotic symptoms and cognitive problems during the COVID-19 outbreak. The frequency of both psychotic symptoms and cognitive problems was associated with time since last conversation, with time since the person last left home and with smaller living space. Participants who reported an increase of psychotic symptoms and cognitive problems during the period of the pandemic also showed higher levels of symptoms. Although social isolation is an effective method for preventing the COVID-19 from spreading, for some individuals it is associated with an increased risk of developing psychotic symptoms.
