How does the public understand the causes of mental disorders? An analysis of Irish news media before and during the COVID-19 pandemic.

Public perceptions of the determinants of mental illness have important implications for attitudes and stigma, but minimal previous research has explored how causal attributions are spontaneously invoked in everyday public discourse. This study investigated how causal explanations for mental illness are disseminated in popular Irish news media, in the two years before and after the onset of the COVID-19 pandemic. Keyword searches of a news media database identified 1,892 articles published between March 2018 to March 2022 that mentioned one of six categories of mental disorders: anxiety disorders, mood disorders, substance-related disorders, personality disorders, eating disorders, and psychotic disorders. Overall, 25% of the identified articles contained a causal explanation for mental illness. Inductive content analysis revealed the content and prevalence of eight types of causal explanations for mental disorders. Overall, attributions to life events/experiences, the cultural/societal environment, interpersonal relations, and health and lifestyle factors occurred more frequently than attributions to biological or psychological determinants. Life events/experiences were the most common explanation for anxiety and personality disorders, cultural/societal environment for eating disorders, and health/lifestyle factors for mood and psychotic disorders. Interpersonal factors in mental illness aetiology became more salient following the COVID-19 pandemic. The findings emphasise the need for theory and research on lay explanations of mental disorders to account for diversity, both in the range of attributions invoked, and in how attributional patterns shift across time and mental disorders category.

Potential mechanisms between psychotic-like experiences and suicidal ideation in the context of COVID-19: A longitudinal study.

OBJECTIVE: Although many studies have found an association between psychotic-like experiences (PLEs) and suicidal ideation (SI), the underlying psychological mechanisms have not been well established. Therefore, we conducted a longitudinal study in technical secondary school and college students to explore the role of fear-response to the COVID-19 and depression in the association between PLEs and SI in the context of the COVID-19 pandemic. METHODS: PLEs were assessed using the 15-item Positive Subscale of the Community Assessment of Psychic Experiences (CAPE-P15). Depression, fear, and SI were assessed using the Psychological Questionnaire for Public Health Emergency (PQPHE). PLEs were evaluated before the pandemic (T1), and fear, depression, and SI were measured during the pandemic (T2). RESULT: A total of 938 students completed both waves of the survey through electronic questionnaires. PLEs, fear, depression, and SI were all correlated with each other (all p < 0.01). T2 depression partly (58.2 %) mediated the relationship between T1 PLEs and T2 SI (b = 0.15, 95%CI = 0.10, 0.22). T2 Fear moderated the relationship between T1 PLEs and T2 depression (b = 0.05, 95%CI = 0.01, 0.09) and the relationship between T1 PLEs and T2 SI (b = 0.11, 95%CI = 0.06, 0.16). CONCLUSION: PLEs are both directly and indirectly related to SI. Depression can result from PLEs and lead to the subsequent SI. Additionally, high levels of fear during the COVID-19 pandemic can aggravate the adverse impact of PLEs on mental health problems. These findings provide potential targets for future suicide prevention.

How does the COVID-19 pandemic affect the personal lives and care realities of people with a schizophrenia spectrum disorder? A qualitative interview study.

BACKGROUND: The COVID-19 pandemic constitutes one of the greatest recent public crises. This study explored its influence on the lives and care realities of people with a schizophrenia spectrum disorder (SSD). METHODS: Between October 2020 and April 2021, semi-structured in-depth interviews were conducted with 30 volunteers with SSDs receiving inpatient or outpatient treatment in Vienna (Austria). Interviews were audio-recorded, transcribed verbatim and analysed thematically. RESULTS: Three main themes were identified. First, 'Pandemic life is deprived, lonely and surreal - though certain aspects can be perceived as positive'. Second, 'Bio-psycho-social support systems were struck at their core by the pandemic and were left severely compromised'. Last, 'There is a complex interplay between one's prior experience of psychosis and the experience of the COVID-19 pandemic'. The pandemic situation affected interviewees in various ways. For many, it led to a drastic reduction in day-to-day and social activities and contributed to an atmosphere of strangeness and threat. Bio-psycho-social support providers frequently suspended their services and offered alternatives were not always helpful. Participants indicated that whilst having an SSD might render them vulnerable to the pandemic situation, prior experience with psychotic crises can also provide knowledge, skills and self-confidence which enable better coping. Some interviewees also perceived aspects of the pandemic situation as helpful for recovering from psychosis. CONCLUSION: Healthcare providers must acknowledge the perspectives and needs of people with SSDs in present and future public health crises to ensure proper clinical support.

Internet Gaming Disorders and Early Onset Psychosis in Young People: A Case Study and Clinical Observations.

BACKGROUND: Over the last ten years, the video game industry has grown exponentially, involving about 2.5 billion young adults in the world. The estimated global prevalence of gaming addiction has been reported to be 3.5% ranging from 0.21% to 57.5% in the general population. Moreover, during the recent COVID-19 pandemic period, school closures and stay-at-home measures have also further increased the opportunities for prolonged and intensified playing of video games. Little is known about the relationship between IGD and psychosis, and the literature is still scarce. Some characteristics of patients with psychosis, particularly those with a first-episode psychosis (FEP), may suggest that these individuals would be particularly liable to develop IGD. CASE PRESENTATION: We report two cases of young patients with to Internet gaming disorder, experiencing early onset psychosis treated with antipsychotic therapy. CONCLUSION: Although it is difficult to show the specific mechanisms underlying the psychopathological alterations in IGD, it is clear that excessive exposure to video games could be a risk factor for precipitating psychosis especially in a vulnerable age group such as adolescence. Clinicians should be aware of the possibility of a higher risk of psychotic onset associated specifically with gaming disorders in very young people.

Psychotic Disorders in the Elderly: Diagnosis, Epidemiology, and Treatment.

This review covers the latest advances in our understanding of psychosis in the elderly population with respect to diagnosis, epidemiology, and treatment. Major topics of discussion include late life psychiatric disorders such as schizophrenia, schizoaffective disorder, and delusional disorder as well as dementia-related psychosis. Clinical differences between early-onset and late-onset disorders are reviewed in terms of prevalence, symptomatology, and approach to treatment. Newly revised research and clinical criteria for dementia-related psychosis are referenced. The evidence base for emerging therapies including citalopram and pimavanserin in relation to conventional therapies such as atypical antipsychotics are discussed..

Incidence rate and distinctive characteristics of first episode psychosis during the COVID-19 pandemic: a multicenter observational study.

The COVID-19 pandemic has affected the mental health of people around the world. However, its impact on first-episode psychosis (FEP) remains unclear. The aim of this study was to determine the incidence rate (IR) and the clinical and sociodemographic characteristics of patients who developed FEP during the nine-month period following the COVID-19 outbreak in Spain and to compare these data to the corresponding period in the previous year. We included all patients (n = 220) treated for the first time during these two time periods at three FEP programs in Spain. The IR was 0.42/100,000 person-years during the pandemic vs. 0.54/100,000 in the prior year (p = 0.057). Compared to prior year, women accounted for a significantly higher proportion of FEP patients (46.3% vs. 28%; p = 0.005) during the COVID-19 period. This association was significant on the logistic regression analysis (odds ratio, female: 2.12 [confidence interval 1.17-3.82]; p = 0.014). These data reveal a non-significant trend towards a lower incidence of FEP during the pandemic period. Female sex was associated with a greater risk of developing FEP during the pandemic period, perhaps due to differences between males and females in the susceptibility and expression of psychosis. The findings of this study contribute to a better understanding of stress-related disorders.

Revolving Door Phenomenon and Related Factors in Schizophrenia, Bipolar Affective Disorder and Other Psychotic Disorders.

BACKGROUND: Patients with chronic mental illness are frequently hospitalized and discharged from psychiatry wards. This situation is referred to as the "revolving door phenomenon" (RDP). In addition to factors related to the patient and the disease, limited number of beds leading to shortened hospital stay are among the reasons associated with frequent hospitalization. This study aims to compare patients with RDP and patients with single hospitalization in terms of clinical, sociodemographic, and treatment-oriented characteristics in order to evaluate the risk factors causing frequent hospitalization. SUBJECTS AND METHODS: In this study, patients who were admitted and hospitalized between May 1, 2011 - May 1, 2016 were retrospectively evaluated from patient records. The RDP group consisted of 74 patients and the single-hospitalization group consisted of 59 patients who met inclusion criteria. RESULTS: The RDP group had significantly higher rates of male gender, ECT history, past suicide attempts, multiple drug treatment, clozapine use, legal incidents, and noncompliance to follow up following discharge compared to the single-hospitalization group (p<0.05). CONCLUSION: This study demonstrates that Turkey also has RDP patients with characteristics and hospitalization patterns similar to patients in countries with different cultural, social, and economic conditions. It is important to identify and correct factors that cause frequent hospitalization as it will reduce the burden of the health system as well as provide benefit to the patient.

The impact of the COVID-19 pandemic on mental health and functional outcomes in Veterans with psychosis or recent homelessness: A 15-month longitudinal study.

BACKGROUND: The COVID-19 pandemic has had unprecedented effects on mental health and community functioning. Negative effects related to disruption of individuals' social connections may have been more severe for those who had tenuous social connections prior to the pandemic. Veterans who have recently experienced homelessness (RHV) or have a psychotic disorder (PSY) are considered particularly vulnerable because many had poor social connections prior to the pandemic. METHODS: We conducted a 15-month longitudinal study between May 2020 -July 2021 assessing clinical (e.g., depression, anxiety) and community (e.g., social functioning, work functioning) outcomes. Eighty-one PSY, 76 RHV, and 74 Veteran controls (CTL) were interviewed over 5 assessment periods. We assessed changes in mental health and community functioning trajectories relative to pre-pandemic retrospective ratings and examined group differences in these trajectories. RESULTS: All groups had significantly increased symptoms of depression, anxiety, and concerns with contamination at the onset of the pandemic. However, RHV and PSY showed faster returns to their baseline levels compared to CTL, who took nearly 15 months to return to baseline. With regards to functioning, both RHV and PSY, but not CTL, had significant improvements in family and social networks over time. Work functioning worsened over time only in PSY, and independent living increased over time in both RHV and PSY but not CTL. CONCLUSIONS: These results reveal that vulnerable Veterans with access to VA mental health and case management services exhibited lower negative impacts of the COVID-19 pandemic on mental health and community functioning than expected.

Mental health provider perspectives of the COVID-19 pandemic impact on service delivery: a focus on challenges in remote engagement, suicide risk assessment, and treatment of psychosis.

BACKGROUND: The COVID-19 pandemic has been impacting the need, utilization, and delivery of mental health services with greater challenges being faced by clients and providers. With many clients facing reduced access to services and social isolation, a focus on suicide risk assessment and prevention is critical. Concern is particularly increased for clients with schizophrenia spectrum disorders given data show suicide rates are disproportionately high for those with psychosis in comparison to the general population. Provider perspectives of challenges in service delivery are needed to inform efforts to improve access, feasibility, and quality of mental health care throughout the evolving pandemic. This study explored mental health provider perspectives of client challenges in service utilization and provider challenges in service delivery, including remote engagement, suicide risk assessment, and treatment of psychosis. METHODS: Data were collected from social work mental health providers (n = 12) in United States community mental health setting. Providers consented to participate and responded to questions about service delivery experiences in late 2020 and in relation to COVID-19. Demographic and practice-related provider data were explored descriptively using SPSS and qualitative data using open coding and grounded theory methods in Dedoose. RESULTS: Among the 9 providers who engaged in remote service delivery, 7 (77.8%) experienced challenges in remote engagement with clients and 8 (88.9%) experienced challenges in treatment of psychosis. Among the 7 providers who engaged in remote suicide assessment, 4(57%) experienced challenges. Qualitative themes emerged including logistic (e.g., technology access and use), engagement (e.g., virtual rapport-building and limited remote services), and clinical (e.g., difficulty assessing suicide risk, internal stimuli, abnormal involuntary movement, and affect) challenges in service delivery. CONCLUSIONS: Provider perspectives are essential to inform efforts to build resources and problem-solve challenges and barriers that both providers and clients face throughout various shifts in mental health service delivery. Findings emphasize the need to troubleshoot client access to technology, bolster support for providers to prevent burnout, and greater provider training to improve skills in remote engagement, assessment, and treatment, particularly in relation to psychosis and suicide prevention. Study implications are not only critical for the evolving COVID-19 pandemic, but also in preparation for ongoing shifts in service delivery as technology evolves.

One-year mortality of emergency department patients with substance-induced psychosis.

OBJECTIVES: Psychosis is a well established complication of non-prescription drug use. We sought to measure the 1-year mortality of emergency department patients with substance-induced psychosis (SIP). METHODS: This study was a multi-centre, retrospective electronic medical records review of patients presenting to the ED with substance-induced psychosis (SIP). We interrogated the hospital ED database from Jan 1, 2018 and Jan 1, 2019 to identify consecutive patients. All patients were followed for one year from index visit, and classified as alive/dead at that time. Patients were included in the study if they met the following criteria: 1) ED discharge diagnosis of psychosis NOS and a positive urine drugs of abuse screen (UDAS) or the patient verbally endorsed drug use, or 2) Mental disorder due to drug use and "disorganized thought", "bizarre behavior" or "delusional behavior" documented in the chart and one or more of the following criteria: a) arrival with police, b) mental health certification, c) physical restraints, d) chemical restraints. We excluded patients who were not British Columbia residents, since we were unable to ascertain if they were alive or dead at 1 year from their index ED visit. Primary statistical analysis was logistic regression for risk of death in 1 year, based on plausible risk factors, selected a priori. RESULTS: We identified 813 presentations for SIP (620 unique patients). The median age of the entire cohort was 35 years (IQR 28-44), and 69.5% (n = 565) were male. Thirty five patients (4.3%; 95% CI 3.2-5.9) had died one year after their initial presentation to the ED for SIP. Separate multivariable logistic regression analyses, controlling for age, demonstrated schizophrenia (OR 4.2, 95% CI 1.8-11.1) significantly associated with increased 1-year mortality. CONCLUSIONS: In our study of patients presenting to the ED with SIP, the 1-year mortality was 4.3%. Controlling for age, schizophrenia was a notable risk factor for increased 1-year mortality.

Psychosis during the COVID-19 pandemic: A systematic review of case reports and case series.

BACKGROUND: Preliminary data suggest that patients with COVID-19 may experience psychiatric symptoms, including psychosis. We systematically reviewed the literature to evaluate the concurrence of new-onset psychosis or exacerbation of clinically stable psychosis through case reports and case series. METHODS: Six databases were searched, followed by an electronic and manual search of the relevant articles. Studies were identified using predetermined eligibility criteria. We evaluated the demographic characteristics, clinical history, course of illness, management, and prognosis of the patients in these studies. RESULTS: Case reports and case series, altogether consisting of 57 unique cases were included. The mean patient age for onset of psychotic symptoms was 43.4 years for men and 40.3 years for women. About 69% of patients had no prior history of psychiatric disorders. Most patients had mild COVID-19-related symptoms, with only 15 (26.3%) presenting with moderate to severe COVID-19-related disease and complications. The most commonly reported psychotic symptoms were delusions and hallucinations. Patients with psychotic symptoms were treated with antipsychotics, benzodiazepines, valproic acid, and electroconvulsive treatment. In 36 cases, psychotic symptoms resolved completely or improved significantly. Ten cases had partial improvement with residual psychotic symptoms, and one patient died due to cardiac arrest. CONCLUSION: Most patients responded to a low-to-moderate dose of antipsychotics with a quick recovery. However, the residual psychiatric symptoms highlight the need for careful monitoring and longer follow-up. Clinicians should be mindful of the occurrence of psychosis due to COVID-19 infection in a subset of COVID-19 patients that can be misdiagnosed as a psychotic disorder alone.

Psychosis risk among pregnant women in Ghana.

INTRODUCTION: Psychotic illness, although is rare, has been reported in the perinatal period. Individuals diagnosed with psychotic illness tend to first exhibit psychotic-like experiences (PLEs), defined as subclinical psychotic symptoms that occur outside the context of sleep or drug use. However, there is a paucity of empirical data on PLEs in pregnancy to advance scholarly discourse and support professional practice. The current study investigated the prevalence and correlates of PLEs among pregnant women in Ghana, a West African state. DESIGN: A cross-sectional survey design was used to collect data from 702 pregnant women who responded to measures of PLEs, COVID-19 concerns and behavioral maladies such as anxiety and depressive symptoms. Descriptive and inferential statistics, namely chi square, exploratory factor analysis, MANOVA and multinomial logistic regression were used to analyze the data. RESULTS: The results showed that 54.2%, 27.3% and 18.5% of participants were at no/low, moderate and high risk for psychosis, respectively. A total of 44.4% participants were not distressed by PLEs, whereas 32.2% and 23.4% were a bit/quite and very distressed, respectively. Psychosis risk was elevated among pregnant women who were more concerned about the COVID-19 effects, scored high in suicidal ideation, depressive symptoms and sleep difficulties. CONCLUSION: The study showed that psychosis risk is present in pregnancy. IMPLICATIONS: Screening for psychosis risk in pregnancy should be prioritized for pregnant women with behavioral maladies, including suicidal tendencies, depressive symptoms, sleep difficulties and heightened concerns about COVID-19.

Comparison of Patients Diagnosed with First Episode Psychosis in the Psychiatry Clinic in the 1-Year Period before and after the COVID-19 Pandemic.

BACKGROUND: Several cases of psychosis caused directly or indirectly by the COVID-19 pandemic have been identified. Especially psychosocial stress factors are thought to trigger first-episode psychosis. The aim of this study was to compare the sociodemographic and clinical features of the cases diagnosed with psychotic disorder for the first time in the two periods 1 year before and 1 year after the date of 11.03.2020, when COVID-19 was first detected in Turkey and COVID-19 was declared as a pandemic by World Health Organization (WHO). SUBJECTS AND METHODS: In this retrospective cohort study, we compared age, gender, marital status, and clinical characteristics of 27 pre-pandemic (PR) and 32 post-pandemic (PS) patients during their first psychotic episode. RESULTS: We compared age, gender and clinical features of PR and PS cases and no statistically significant difference was found (age p=0.836, gender p=0.091, clinical features p=0.579). CONCLUSIONS: There are a limited number of studies comparing first-episode psychosis (FEP) patients in the PR and PS periods. This is the first study conducted in Turkey on this subject. The present study may contribute to the literature by examining the impact of the pandemic process on the epidemiology of psychiatric diseases.

First-episode psychotic disorders in the wake of the COVID-19 pandemic: a descriptive review of casereports.

OBJECTIVE: Since the onset of COVID-19 pandemic, many case reports and case series dealt with new-onset psychotic disorders in patients either infected with SARS-CoV-2 or thematically linked to the pandemic, but without an infection. Our aim was to provide a comprehensive collection of these reports to illustrate the nature of these psychoses. METHODS: We conducted a literature search in MEDLINE, Embase, PsycINFO, using search terms regarding first-episode psychotic disorders in the context of corona. RESULTS: 96 case reports or case series covering 146 patients (62 without and 84 with SARS-CoV-2 infection) were found. Compared to patients without infection, patients with infection showed significantly more often visual hallucinations (28.6% vs 8.1%), confusion (36.9% vs 11.3%), an acute onset of illness (88.5% vs 59.6%) and less often depression (13.1% vs 35.5%) and a delusional content related to the pandemic (29.5% vs 78.3%). Both groups had an equally favourable outcome with a duration of psychosis ≤2 weeks in half and full remission in two-thirds of patients. In patients with infection, signs of inflammation were reported in 78.3% and increased CRP in 58.6%. While reports on patients with infection are continuously published, no report about patients without infection was found after July 2020. CONCLUSION: Cases without infection were considered reactive and originated all from the first wave of the corona pandemic. In cases with infection, inflammation was considered as the main pathogenetic factor but was not found in all patients. Diagnosis was impeded by the overlap of psychosis with delirium.

Disentangling early and late onset of psychosis in women: identifying new targets for treatment.

Women present a second peak of incidence of psychosis during the menopausal transition, partially explained by the loss of estrogen protection conferred during the reproductive years. In view of the lack of studies comparing sociodemographic, biological, and clinical variables and neurocognitive performance between women with early onset of psychosis (EOP) and those with late onset of psychosis (LOP), our aim was to characterize both groups in a large sample of 294 first-episode psychosis (FEP) patients and 85 healthy controls (HC). In this cross-sectional study, the participants were interviewed to gather information on sociodemographic variables. We assessed laboratory features of interest and conducted a clinical assessment of psychopathological symptoms and neurocognitive abilities. From the latter, we derived a global cognitive functioning score. Analysis of covariance (ANCOVA) was used to compare EOP and LOP groups, and each group with age-comparable HC. EOP women were more frequently single and unemployed than HC age peers. While cholesterol levels in LOP women were higher than those in EOP women, no statistically significant differences were found in leptin levels. Women with LOP presented with less severe negative symptoms and higher cognitive processing speed scores than women with EOP. Cannabis and alcohol use was greater in EOP than in LOP women. Within the total FEP group, there was a history of significantly more recent traumatic events than in the HC group. Women with EOP and LOP show several sociodemographic and clinical differences, which may be valuable for planning personalized treatment.

Psychotic disorders amid the COVID-19 pandemic: a consideration of risks and impacts.

PURPOSE OF REVIEW: The COVID-19 pandemic has had a severe and widespread global impact but particularly for those with psychosis. This review summarizes recent evidence on the relationship between the COVID-19 pandemic and psychotic disorders, highlighting the risks faced by these individuals including the negative impacts on treatment services, complications from contracting COVID-19, and the acceptability of digital interventions. RECENT FINDINGS: Mortality, morbidity, and infection outcomes are among the worst for individuals with psychotic disorders. Presentation rates for psychotic disorders are elevated at emergency departments compared with before the COVID-19 pandemic; demand for inpatient services has increased, and there have been complications in access because of pandemic restrictions. COVID-19 related stressors have led to the exacerbation and incidence of psychotic symptoms among individuals with and without preexisting psychotic diagnoses. Digital interventions may be an acceptable method for maintaining patient contact and treatment during extended isolation. SUMMARY: More data is needed on the longitudinal trajectory for psychotic symptoms post-COVID-19 infection and pandemic restrictions to better support individuals with psychotic disorders. Development of a long-term pandemic management plan is needed to monitor and support psychiatric health across the population.

COVID-related hospitalization, intensive care treatment, and all-cause mortality in patients with psychosis and treated with clozapine.

Clozapine, an antipsychotic, is associated with increased susceptibility to infection with COVID-19, compared to other antipsychotics. Here, we investigate associations between clozapine treatment and increased risk of adverse outcomes of COVID-19, namely COVID-related hospitalisation, intensive care treatment, and death, amongst patients taking antipsychotics with schizophrenia-spectrum disorders. Using the clinical records of South London and Maudsley NHS Foundation Trust, we identified 157 individuals who had an ICD-10 diagnosis of schizophrenia-spectrum disorders, were taking antipsychotics (clozapine or other antipsychotics) at the time of COVID-19 pandemic in the UK and had a laboratory-confirmed COVID-19 infection. The following health outcomes were measured: COVID-related hospitalisation, COVID-related intensive care treatment and death. We tested associations between clozapine treatment and each outcome using logistic regression models, adjusting for gender, age, ethnicity, neighbourhood deprivation, obesity, smoking status, diabetes, asthma, bronchitis and hypertension using propensity scores. Of the 157 individuals who developed COVID-19 while on antipsychotics (clozapine or other antipsychotics), there were 28% COVID-related hospitalisations, 8% COVID-related intensive care treatments and 8% deaths of any cause during the 28 days follow-up period. amongst those taking clozapine, there were 25% COVID-related hospitalisations, 7% COVID-related intensive care treatments and 7% deaths. In both unadjusted and adjusted analyses, we found no significant association between clozapine and any of the outcomes. Thus, we found no evidence that patients with clozapine treatment at time of COVID-19 infection had increased risk of hospitalisation, intensive care treatment or death, compared to non-clozapine antipsychotic-treated patients. However, further research should be considered in larger samples to confirm this.

Correlates of psychotic like experiences (PLEs) during Pandemic: An online study investigating a possible link between the SARS-CoV-2 infection and PLEs among adolescents.

BACKGROUND: This study investigated whether SARS-CoV-2 infection, depression, anxiety, sleep problems, cigarette, alcohol, drug usage contribute to psychotic-like experiences (PLEs) among adolescents during the pandemic. We also aimed to explore whether baseline inflammatory markers or the number of SARS-CoV-2-related symptoms are associated with PLEs, and the latter is mediated by internalizing symptoms. METHODS: Altogether, 684 adolescents aged 12-18 (SARS-CoV-2 group n = 361, control group (CG) n = 323) were recruited. The Community Assessment of Psychic Experiences-42-Positive Dimension (CAPE-Pos), Patient Health Questionnaire-9 (PHQ-9), Generalized Anxiety Disorder-7 (GAD-7), and Pittsburg Sleep Quality Index (PSQI) questionnaires were completed by all volunteers using an online survey. C-reactive Protein and hemogram values, and SARS-CoV-2-related symptoms during the acute infection period were recorded in the SARS-CoV-2 group. Group comparisons, correlations, logistic regression, and bootstrapped mediation analyses were performed. RESULTS: CAPE-Pos-Frequency/Stress scores were significantly higher, whereas GAD-7-Total and PSQI-Total scores were significantly lower in SARS-CoV-2 than CG. Among the SARS-CoV-2 group, monocyte count and the number of SARS-CoV-2-symptoms were positively correlated with CAPE-Pos-Frequency/Stress scores. Besides SARS-CoV-2, cigarette use, GAD-7, and PHQ-9 scores significantly contributed to the presence of at least one CAPE-Pos "often" or "almost always". PHQ-9 and GAD-7 fully mediated the relationship between the number of SARS-CoV-2 symptoms and CAPE-Pos-Frequency. CONCLUSIONS: This study is the first to show a possible relationship between SARS-CoV-2 infection and PLEs among adolescents. Depression, anxiety, and cigarette use also contributed to PLEs. The number of SARS-Cov-2-symptoms and PLEs association was fully mediated by internalizing symptoms, but prospective studies will need to confirm this result.
