Obsessive-Compulsive Disorder During the COVID-19 Pandemic-A Systematic Review

Increases in symptoms associated with obsessive-compulsive disorder among university students during the COVID-19 pandemic

OBJECTIVE

The long-term consequences of the COVID-19 pandemic on college students' mental health remains unknown. The current study explored self-reported Obsessive-Compulsive symptomatology among college student cohorts from pre-, peak-, and later-pandemic time points.

PARTICIPANTS

Undergraduate college students (N = 524) who volunteered for course credit.

METHODS

Self-report responses on the Dimensional Obsessive-Compulsive Scale (DOCS), which includes subscales for contamination, unacceptable thoughts, harm responsibility, and symmetry, were collected from November 29, 2016 through April 27, 2021 and assessed for differences between the pre-, peak-, and later-pandemic cohorts.

RESULTS

Peak-pandemic responders reported higher symptomatology for contamination and unacceptable thoughts compared to pre-pandemic responders (and for pre- vs. later-pandemic for contamination), with no significant effects for symmetry or harm responsibility.

CONCLUSIONS

Although the longer-term consequences of the COVID-19 pandemic on students remains unknown, a greater shift in college mental health services from prevention to assessing and addressing more immediate challenges may be necessary.

Obsessive compulsive disorder: overview of the condition and its nursing management

Obsessive compulsive disorder (OCD) is a complex condition characterised by intrusive and distressing thoughts (obsessions) and repetitive behaviours or mental acts (compulsions). The symptoms of OCD cause significant distress and anxiety and can have a debilitating effect on a person's daily functioning. This article gives an overview of OCD, including its prevalence, aetiology, symptoms and treatment strategies, with the aim of enhancing nurses' understanding of the condition and its adverse effects on a person's life. The author also discusses some of the ways in which nurses in any setting can support a person with OCD.

ØCD: protocol for the development and evaluation of a cognitive-behavioral prevention program for obsessive-compulsive disorder

BACKGROUND

Obsessive-compulsive disorder (OCD) imposes significant burdens on individuals, families, and healthcare systems and the COVID-19 pandemic appears to have exacerbated OCD symptoms. Currently, there are no validated prevention programs for OCD, highlighting a critical gap in mental health services. This study aims to develop and validate the first ØCD prevention program, for at-risk adults, utilizing cognitive-behavioral therapy (CBT) and exposure response prevention (ERP) techniques.

METHODS

A single-blind, randomized controlled trial comparing the ØCD prevention program to a waitlist control group will be conducted. Participants, at-risk adults (18-65 years) with subclinical OCD symptoms (OCI-R score ≥ 12), will be recruited for the study. The ØCD prevention program compresise of six online group sessions incorporating CBT and ERP techniques over three modules. The primary outcomes are OCD symptom severity (measured by the Obsessive-Compulsive Inventory- revised form; OCI-R), depression symptoms (measured by the Patient Health Questionnaire; PHQ-9), and anxiety symptoms (measured by the Generalised Anxiety Disorder 7-item; GAD-7). Secondary outcomes include OCD-related beliefs, experiential avoidance, resilience, quality of life, uncertainty intolerance, automatic thoughts, and distress. Outcome measures will be collected at baseline, at completion of the intervention, and one year later (follow-up). At follow-up, we will also analyze the OCD diagnostic incidence, using the Structured Clinical Interview for DSM-5. We will employ a multivariate analysis of variance (MANOVA) to explore whether significant differences exist between groups across dependent variables. To compare the OCD incidence levels from the pre-test to the follow-up we will use the chi-squared test.

DISCUSION

The present study may contribute novel data on the efficacy of OCD prevention approaches, leading to the development of an evidence-based OCD prevention program that could alleviate individual and societal burdens associated with OCD.

TRIAL REGISTRATION

This trial was approved by the University Ethical Review Authority (937/ 28.11.2023) at Babeș-Bolyai University and is registered on clinicaltrials.gov (ID: NCT06262464).

Worldwide prevalence of obsessive-compulsive symptoms during the COVID-19 pandemic: A systematic review and meta-analysis

During the COVID-19 pandemic governments worldwide implemented contagion-containing measures (i.e., physical distancing, hand sanitizing, mask wearing and quarantine). The similarities between these measures and obsessive-compulsive phenomenology (e.g., contamination concerns and repetitive washing and/or checking) led to inquiries about the frequency with which obsessive-compulsive symptoms (OCS) were encountered during the COVID-19 pandemic. We conducted a systematic review and meta-analysis to ascertain the prevalence of OCS in individuals of any age during the pandemic (i.e., any obsessive-compulsive symptoms that are clinically significant as shown by a score above the cut-off score of a scale, without necessarily fulfilling the diagnostic threshold for a diagnosis of OCD). A systematic search of relevant databases identified 35 studies, which were included in the systematic review following our inclusion and exclusion criteria. Most of the studies were conducted in adults from the general population and adopted an online assessment method, with 32 studies being eligible for meta-analysis. The meta-analysis resulted in a 20% average prevalence of OCS during the pandemic, with very high heterogeneity among the included studies (I2 99.6%). The highest prevalence of OCS was found in pregnant women (36%, n = 5), followed by individuals diagnosed with COVID-19 (22%, n = 4) and general population (22%, n = 19), undergraduates (21%, n = 5), and healthcare workers (5%, n = 5). The prevalence rates of OCS were higher in Asia (26%, n = 17) and North America (25%, n = 3) than in Europe (13%, n = 12) and Africa (7%, n = 4). Among the studies included, rates appeared higher in certain countries, though this difference did not reach statistical significance and was limited by very few studies conducted in certain countries. When compared to pre-pandemic rates, there seemed to be higher rates of OCS during the COVID-19 pandemic in Asia, Europe, and pregnant women. These findings are discussed considering the impact of the pandemic and contagion-containing measures on the perception and reporting of OCS, and susceptibility of the vulnerable population groups to experiencing OCS during the pandemic.

Longitudinal trajectories of anxiety and depression in subjects with different mental disorders after one year in the COVID-19 pandemic

The aim of this study was to prospectively assess the development and trajectories of anxiety and depressive symptoms among subjects with different mental disorders, during the 3rd wave of the COVID-19 pandemic (T0, March-April 2021) while strict containment measures were applied in Italy, and after 3 months (T1, June-July 2021), with reduced restrictive measures. A sample of 527 subjects, with different DSM-5 diagnoses, was enrolled at nine Italian psychiatric outpatient services. Assessments at T0 and T1 included the Generalized Anxiety Disorder 7-Item (GAD-7) for anxiety symptoms, and the Patient Health Questionnaire-9 (PHQ-9) for depressive symptoms. Differences in anxiety and depressive symptoms rates emerged across different mental disorders and a general improvement at T1 was detected for all of them in both the GAD-7 and PHQ-9 scores, except for Psychosis and Obsessive-Compulsive Disorder (OCD). Patients with Feeding and Eating Disorders (FED) reported statistically significantly higher: GAD-7 scores than those with Bipolar Disorder (BD), at both times, and Anxiety Disorders at baseline; PHQ-9 scores than all other diagnostic categories, at both times. Unemployment, no COVID-19 infection, OCD were predictive variables related to GAD-7 scores at T1, while being unmarried, BD or FED related to PHQ-9 scores at T1. Subjects with mental disorders reported anxiety and depressive symptoms during the third pandemic wave and most of patients showed an improvement over a 3-month follow-up, despite differences emerged among diagnostic categories and for the variables involved. Further studies are needed to deepen knowledge on pandemic impact on patients with mental disorders.

Establishing an OCD Model in BALB/c Mice Using RU24969: A Molecular and Behavioural Study of Optimal Dose Selection

Obsessive-compulsive disorder (OCD) is a disabling disease characterized by distressing obsessions and repetitive compulsions. The etiology of OCD is poorly known, and mouse modeling allows to clarify the genetic and neurochemical basis of this disorder and to investigate potential treatments. This study evaluates the impact of the 5-HT1B agonist RU24969 on the induction of OCD-like behaviours in female BALB/c mice (n = 30), distributed across five groups receiving varying doses of RU24969. Behavioural assessments, including marble test, tail suspension test, sucrose preference test, forced swim test, and nestlet shredding test, were conducted. Gene expression and protein quantitation of Gabra1 and serotonin transporter in mouse brain were also performed. Marble-burying behaviour increased significantly at high doses of RU24969 (15-20 mg/kg). The forced swimming test consistently showed elevated values at the same high concentrations, compared to the control. Altered reward-seeking behaviour was indicated by the sucrose preference test, notably at 15 and 20 mg/kg doses of RU24969. Nestlet shredding results did not show statistical significance among the tested animal groups. Gene expression analysis revealed reduced Gabra1 expression with increasing doses of RU, while serotonin transporter was not related to varying doses of RU24969. Western blotting corroborated these trends. The results underscore complex interactions between the serotonin system, GABAergic signaling, and OCD-relevant behaviours and suggest the use of intraperitoneal injection of 15 mg/kg of RU24969 to induce OCD-like behaviour in BALB/c mouse models.

Contamination-Focussed Vignettes as an Analogue of Infectious Pandemics: An Experimental Validation using the State Disgust and Anxiety Responses in OCD

Despite infectious pandemics proving particularly detrimental to those with Obsessive-Compulsive Disorder (OCD), the investigation of analogous experimental paradigms is lacking. To address this gap, we conducted two studies employing vignettes that depicted contamination-related situations commonly experienced during a pandemic (e.g., Coughing into hands and failing to use hand sanitizer). We manipulated the salience of these vignettes across three levels: high contamination, low contamination, and a neutral control condition. Our examination of state anxiety and disgust responses in all participants revealed the successful manipulation of the vignettes' impact. Specifically, individuals with more severe OCD symptoms reported significantly higher levels of state disgust and anxiety for both high and low contamination vignettes, in contrast to the group with lower symptom severity. No significant differences were observed in the neutral vignette condition between the high- and low-scoring groups. Interestingly, for those with higher OCD symptoms, high salience contamination-focused vignettes resulted in similarly elevated state disgust and anxiety, regardless of whether the vignettes were situated in public (Study 1) or domestic (Study 2) settings. This suggests that the heightened sensitivity to contamination-related scenarios observed in individuals with OCD symptoms in the present study is not confined to a specific context. These findings support the use of contamination-focused vignettes as analogues for studying infectious pandemics and provide valuable insights into OCD models, interventions, and future research.

Too much of a good thing? Hand hygiene and the long-term course of contamination-related obsessive-compulsive symptoms

Increased hygiene behavior may be a factor in the development of contamination-related obsessive-compulsive symptoms (C-OCS). We aimed at investigating (1) the course of C-OCS over 1 year after the start of the COVID-19 pandemic and (2) the effects of changes in hand hygiene (i.e., duration and frequency of handwashing) and related distress regulation on the long-term course of C-OCS. In a longitudinal study, we assessed 1,220 individuals from the German general population at the start of the COVID-19 pandemic (t1), 3 months later (t2), and 12 months later (t3). Pre-pandemic data were available in a subsample from 2014 (n = 430). A decrease in C-OCS over the first year of the pandemic emerged with a small effect size. Thirty-six percent of the participants scored above the clinical cut-off score at t1, 31% at t2, and 27% at t3. In 2014, only 11% scored above the clinical cut-off score. Hierarchical regression showed that C-OCS at t1 was the strongest predictor of a long-term increase in C-OCS. With small effect sizes, change in the duration (not frequency) of handwashing from t1 to t2, as well as the distress-reducing effect of handwashing served as additional predictors. Implications for information on hand hygiene guidelines are discussed.

SARS-CoV-2 and Adolescent Psychiatric Emergencies at the Tübingen University Hospital: Analyzing Trends, Diagnoses, and Contributing Factors

Psychiatric emergencies have increased in recent decades, particularly with the onset of the SARS-CoV-2 pandemic, and far too little is known about the backgrounds of these emergencies. In this study, we investigated the extent to which the number of psychiatric emergencies changed during and in the aftermath of the SARS-CoV-2 pandemic at the Child and Adolescent Psychiatry (CAP) Tübingen. We considered age and psychiatric diagnoses. Additionally, we evaluated the backgrounds of the emergencies. We applied a mixed- (quantitative and qualitative) methods approach to data on emergency presentations at the CAP Tübingen from the pre-SARS-CoV-2 pandemic period (October 2019-January 2020) to Restriction Phase 1 (October 2020-January 2021), Restriction Phase 2 (October 2021-January 2022), and endemic phase (October 2022-January 2023). The total number of emergencies and those with eating disorders and affective disorders increased, while obsessive-compulsive disorders, expansive disorders and anxiety disorders decreased. The patients presenting in the pre-SARS-CoV-2 pandemic period were younger than those in the subsequent periods. We content-coded the reasons behind the emergency presentations. We also identified four areas of stressors and personality characteristics associated with the emergency presentations. In light of the increasing number of psychiatric emergencies, the long-term aim should be to meet the growing demands and create options for prevention.

Impact of the COVID-19 pandemic on the symptomatology and routine of medicated patients with obsessive-compulsive disorder

OBJECTIVES

To study the impact of coronavirus disease 2019 on the routine of patients with obsessive-compulsive disorder (OCD) and changes in symptoms and suicidal-related behavior, mainly in those with cleaning symptoms.

METHODS

In this cross-sectional study, 58 patients completed an online self-report questionnaire that included the Obsessive-Compulsive Inventory-Revised, Coronavirus Stress and Traumatic Events Scale, Coronavirus Health Impact Survey, Beck Anxiety and Beck Depression inventories, and Suicide-Related Behaviors Questionnaire. Comparisons were made with another pre-pandemic sample (n=524) regarding the last three measures.

RESULTS

During the pandemic, the patients spent more days inside their homes (χ² = 33.39, p = 0.007), changed their alcohol consumption patterns (χ² = 87.6, p < 0.001), and increased social media usage (χ² = 68.83, p < 0.001). Participants with cleaning symptoms did not significantly differ from the others in relation to stress, anxiety/depressive symptoms, or suicidal-related behaviors. Finally, our sample did not differ from an equivalent OCD sample assessed before the pandemic in terms of anxiety and depressive symptom severity or suicidal-related behaviors.

CONCLUSION

Overall, patients with OCD showed no lifestyle changes associated with higher stress levels during the pandemic. Patients with and without cleaning symptoms and patients before and during the pandemic presented similar results.

Effects of the COVID-19 Pandemic on University Students' Mental Health: A Literature Review

This review aims to focus on the effects of COVID-19 on university students' mental health and deepen our understanding of it. The conclusions are based on the review of 32 studies conducted during the pandemic. This review confirms that university students were at high risk for mental health disorders, heightened stress, and increased sleep comorbidities both pre-pandemic and during the pandemic. This literature review confirmed a few universal trends, i.e., increased stress, anxiety, and depression, during the pandemic. The rates of insomnia, obsessive-compulsive disorder, and suicidal ideation also went up. Overall, female students are at a disadvantage in the development of mental health issues. Male students coped better but may be at higher risk for lethality in suicidal ideation. Students with a history of mental health issues and other comorbidities prior to the pandemic had worse outcomes compared to healthy individuals. The study points to a strong positive correlation between fear and increased rates of stress, anxiety, and insomnia. There is also a positive correlation between declining mental health and online learning. A strong negative correlation was present between physical activity and depressive symptoms. These findings are universal across many countries and regions where the studies occurred.

Obsessive-compulsive disorder among individuals of Hispanic and Latin American ancestry: Cultural considerations for assessment and psychotherapy

Research specific to obsessive-compulsive disorder (OCD) among individuals of Hispanic and Latin American (H/L) ancestry is limited, as are culturally relevant assessment and treatment recommendations. This article discusses the implications of underrepresentation of H/L populations in OCD research and emphasizes the need to consider issues related to assessment, treatment, and structural barriers that hinder delivery of culturally appropriate first-line psychotherapy. Recommendations for assessment and treatment are provided to aid clinicians in distinguishing culturally normative thoughts and behaviors from OCD, as well as to inform the implementation of psychotherapeutic interventions with cultural humility. This manuscript offers recommendations for future research to tackle health equity concerns with respect to assessment and treatment and structural factors limiting access to culturally appropriate psychotherapy. Wide-scale efforts are needed to comprehensively understand how H/L cultures intersect with various OCD presentations and to further disseminate treatments to populations that have historically lacked access to mental health care.

Long-term impact of the COVID-19 pandemic on obsessive-compulsive disorder

There is limited data on the long-term effect of the COVID-19 pandemic on obsessive-compulsive disorder (OCD). We report on the course of a cohort of individuals with OCD followed-up over a period of one year during the first wave of the COVID-19 pandemic in India. A cohort of 240 individuals registered at a specialty OCD clinic was regularly followed-up using standardized rating tools at three months, six months, and one year into the onset of the COVID-19 pandemic in India. These were compared with clinical ratings recorded in a comparable historical cohort of 207 individuals with OCD, followed up during a non-pandemic year. The pandemic and non-pandemic (historical control) cohorts did not differ in illness severity and rate of relapse. It was found that COVID-19-related anxiety declined over time. Among those patients who were treatment responders prior to the pandemic, COVID-19-related anxiety and non-adherence to medication predicted a relapse of symptoms. Contrary to our expectations, the rate of relapse and illness trajectory in the pandemic cohort did not differ from the non-pandemic cohort, suggesting that the pandemic did not impact our largely medication-adherent cohort. Adherence to treatment seemed to have a protective effect during the pandemic.

Prevalence of obsessive-compulsive disorders (OCD) symptoms among health care workers in COVID-19 pandemic: a systematic review and meta-analysis

BACKGROUND

Obsessive Compulsive Disorder (OCD) symptoms, are among the serious mental health challenges that Health Care Workers (HCWs) faced during the COVID-19 pandemic. As these symptoms reduce the mental well-being and effectiveness of HCWs which are followed by poor health outcomes for patients, the aim of this systematic review and meta-analysis was to determine the prevalence of OCD symptoms among HCWs worldwide.

METHODS

PubMed, Google Scholar, Cochrane, Scopus, Web of Science, ProQuest, Emerald, and ERIC databases were searched using related keywords till the end of October 2021. Observational studies about the prevalence of OCD symptoms among healthcare workers during the COVID-19 pandemic were screened and evaluated. In order to assess the quality of studies, the Newcastle-Ottawa scale (NOS) checklist was used. The effect measure was the prevalence rate with a 95% confidence interval (CI).

RESULTS

A total of 7864 individuals from 11 studies were included. The range of OCD symptoms prevalence across these studies was from 0.07 to 0.47. Due to the high heterogeneity between the studies (I2 = 98.6%, P < 0.01), the random effects model was used. The pooled prevalence was 0.29 (95% CI: 0.22-0.38) based on logit transformed CI.

CONCLUSIONS

The pooled prevalence of OCD symptoms was 29% among the HCWs during the COVID-19 pandemic. This prevalence was higher than the general population according to the pre-pandemic literature, but lower than the recent reports amid the pandemic. Psychosocial interventions are suggested to be designed and implemented in such conditions.

Contact with primary care physicians among adults with pre-existing common mental health problems during the COVID-19 pandemic: a registry-based study from Norway

BACKGROUND

During the COVID-19 pandemic, individuals with pre-existing mental health problems may have experienced additional stress, which could worsen symptoms or trigger relapse. Thus, this study aimed to investigate if the number of consultations with general practitioners (GPs) among individuals with a pre-existing common mental health problem during the pandemic differed from pre-pandemic years.

METHODS

Data on consultations with GPs among 18-65-year-olds registered with common mental health problems in 2017-2021 were retrieved from the Norwegian Control and Payment of Health Reimbursements Database. Based on data from the pre-pandemic years (2017-2019), we predicted the number of consultations per week for depression, anxiety disorder, phobia/obsessive-compulsive disorder (OCD), post-traumatic stress disorder (PTSD), and eating disorders during the pandemic (March 2020-December 2021) among individuals with pre-existing mental health problems. The forecasted and observed trends in GP consultations per week during the pandemic were stratified by diagnosis, gender, and age groups.

RESULTS

The observed number of consultations for anxiety disorder, PTSD, and eating disorders were significantly higher than forecasted during extended periods of the two pandemic years. The differences were largest for PTSD (on average 37% higher in men and 47% higher in women during the pandemic), and for eating disorders among women (on average 87% higher during the pandemic). There were only minor differences between the predicted and observed number of consultations for depression and phobia/OCD.

CONCLUSIONS

During the pandemic, individuals with a recent history of mental health problems were more likely to seek help for anxiety disorder, PTSD, and eating disorders, as compared to pre-pandemic years.

Incidence rates of treated mental disorders before and during the COVID-19 pandemic-a nationwide study comparing trends in the period 2015 to 2021

BACKGROUND

There is a concern that exposure to psychosocial stressors during the COVID-19 pandemic may have led to a higher incidence of mental disorders. Thus, this study aimed to compare trends in incidence rates of depressive disorder, anxiety disorders, obsessive-compulsive disorder (OCD), post-traumatic stress disorder (PTSD), and eating disorders in primary- and specialist health care before (2015-2019) and during the COVID-19 pandemic (2020-2021).

METHODS

We used aggregated population registry data to calculate incidence rates of mental disorders from primary- (The Norwegian Control and Payment of Health Reimbursements Registry (KUHR)) and specialist (The Norwegian Patient Registry (NPR)) health care. The analyses included all Norwegian residents aged 18-65 during the study period. Incident cases were defined as having no previous registration with the same mental disorder in KUHR (from 2006) or NPR (from 2008). We used linear prediction models and mean models to compare incidence rates and test trends before and during the pandemic.

RESULTS

During the pandemic, the incidence rates among women were higher or as predicted for OCD in specialist health care and for eating disorders in both primary- and specialist health care. These findings were strongest among women aged 18-24 years. Incidence rates for depression and phobia/OCD among both genders in primary health care and phobic anxiety disorders among both genders in specialist health care were lower or as predicted.

CONCLUSION

The COVID-19 pandemic may have led to more women needing treatment for OCD and eating disorders in the Norwegian population. The decreased incidence rates for some disorders might indicate that some individuals either avoided seeking help or had improved mental health during the pandemic.

Online versus in-person delivery of cognitive behaviour therapy for obsessive compulsive disorder: An examination of effectiveness

Cognitive behavioural therapy (CBT) including exposure and response prevention is the first-line psychological treatment for obsessive compulsive disorder (OCD). Given changes in the clinical landscape, there are increasing efforts to evaluate its effectiveness in online contexts. Mirroring the traditional in-person delivery, few studies have assessed the role of therapist-guided, manual-based CBT for OCD delivered in real-time via videoconferencing methods. The present study sought to fill this gap by comparing in-person and online delivery of group-based CBT for the treatment of OCD. A convenience sample of participants with moderate to severe OCD (n = 144) were recruited from a naturalistic database from two large OCD specialty assessment and treatment centres. Patients received group-based CBT that was provided in-person (pre-COVID-19 pandemic; March 2018 to March 2020) or online via videoconferencing (during the COVID-19 pandemic; March 2020 to April 2021). In both delivery methods, treatment consisted of 2-h weekly sessions led by trained clinicians. Analyses revealed that, regardless of treatment modality, both in-person and online groups demonstrated significant, reliable, and statistically equivalent improvements in OCD symptoms post-treatment. Videoconferenced, clinician-led CBT may be a promising alternative to in-person delivery for those with moderate to severe OCD symptoms.

Longitudinal Course of Obsessive-Compulsive Symptoms During the Covid-19 Pandemic: A Systematic Review of Three Years of Prospective Cohort Studies

Objective

During the pandemic, there has been a slight increase in obsessive-compulsive symptoms in both clinical and non-clinical samples. Three years after the pandemic, we conducted the first systematic review of prospective cohort studies assessing temporal changes in obsessive-compulsive symptoms and their extent in both patients with obsessive-compulsive disorder (OCD) and community samples, regardless of age or socio-cultural background, during any phase of the pandemic.

Method

Prospective cohort studies were included if validated self-report questionnaires or standardized interviews for obsessive-compulsive symptoms were used. Studies that enrolled OCD patients were included if OCD was diagnosed before the outbreak of the pandemic. The following were our exclusion criteria: cross-sectional and case-control studies, single case studies, editorials, commentaries, and reviews. Studies assessing the effectiveness of an intervention were excluded.

Results

15 studies were included. Overall, studies showed a small upsurge in obsessive-compulsive symptoms, especially washing/contamination symptoms, during the coronavirus outbreak. The severity of symptoms seemed to follow the pattern of restriction measures and the increase in the number of COVID-19 cases.

Conclusions

Factors contributing to the worsening of obsessive-compulsive symptoms during the pandemic were discussed.

Long COVID, the Brain, Nerves, and Cognitive Function

SARS-CoV-2, a single-stranded RNA coronavirus, causes an illness known as coronavirus disease 2019 (COVID-19). Long-term complications are an increasing issue in patients who have been infected with COVID-19 and may be a result of viral-associated systemic and central nervous system inflammation or may arise from a virus-induced hypercoagulable state. COVID-19 may incite changes in brain function with a wide range of lingering symptoms. Patients often experience fatigue and may note brain fog, sensorimotor symptoms, and sleep disturbances. Prolonged neurological and neuropsychiatric symptoms are prevalent and can interfere substantially in everyday life, leading to a massive public health concern. The mechanistic pathways by which SARS-CoV-2 infection causes neurological sequelae are an important subject of ongoing research. Inflammation- induced blood-brain barrier permeability or viral neuro-invasion and direct nerve damage may be involved. Though the mechanisms are uncertain, the resulting symptoms have been documented from numerous patient reports and studies. This review examines the constellation and spectrum of nervous system symptoms seen in long COVID and incorporates information on the prevalence of these symptoms, contributing factors, and typical course. Although treatment options are generally lacking, potential therapeutic approaches for alleviating symptoms and improving quality of life are explored.

Screen Time and Obsessive-Compulsive Disorder Among Children 9-10 Years Old: A Prospective Cohort Study

PURPOSE

The aim of this study is to determine the prospective associations between baseline screen time and obsessive-compulsive disorder (OCD) at 2-year follow-up in a national (United States) cohort of 9- to 10-year-old children.

METHODS

We analyzed prospective cohort data from the Adolescent Brain Cognitive Development study (n = 9,208). Logistic regression analyses were used to determine the associations between baseline self-reported screen time (exposure) and OCD, based on the Kiddie Schedule for Affective Disorders and Schizophrenia (outcome), at 2-year-follow-up, adjusting for race/ethnicity, sex, household income, parent education, family history of psychopathology, and study site, excluding participants with baseline OCD.

RESULTS

The sample was 48.9% female and racially and ethnically diverse (43.5% non-White). Each additional hour of total screen time was prospectively associated with 1.05 higher odds of OCD at 2-year follow-up (95% confidence interval [CI] 1.01-1.09). For specific screen time modalities, each additional hour of playing video games (adjusted odds ratio 1.15, 95% CI 1.03-1.28) and watching videos (adjusted odds ratio 1.11, 95% CI 1.01-1.23) was associated with a subsequent OCD diagnosis.

CONCLUSION

Video games and watching videos are prospectively associated with new-onset OCD in early adolescents. Future research should examine mechanisms linking these specific screen modalities to OCD development to inform future prevention and intervention efforts.

Age-specific determinants of psychiatric outcomes after the first COVID-19 wave: baseline findings from a Canadian online cohort study

BACKGROUND

Canadians endured unprecedented mental health (MH) and support access challenges during the first COVID-19 wave. Identifying groups of individuals who remain at risk beyond the acute pandemic phase is key to guiding systemic intervention efforts and policy. We hypothesized that determinants of three complementary, clinically actionable psychiatric outcomes would differ across Canadian age groups.

METHODS

The Personal Impacts of COVID-19 Survey (PICS) was iteratively developed with stakeholder feedback, incorporating validated, age-appropriate measures. Baseline, cross-sectional online data collected between November 2020-July 2021 was used in analyses. Age group-specific determinants were sought for three key baseline MH outcomes: (1) current probable depression, generalized anxiety disorder, obsessive-compulsive disorder and/or suicide attempt during COVID-19, (2) increased severity of any lifetime psychiatric diagnosis, and (3) inadequate MH support access during COVID-19. Multivariable logistic regression models were constructed for children, youth (self- and parent-report), young adults (19-29 years) and adults over 29 years, using survey type as a covariate. Statistical significance was defined by 95% confidence interval excluding an odds ratio of one.

RESULTS

Data from 3140 baseline surveys were analyzed. Late adolescence and early adulthood were identified as life phases with the worst MH outcomes. Poverty, limited education, home maker/caregiver roles, female and non-binary gender, LGBTQ2S + status and special educational, psychiatric and medical conditions were differentially identified as determinants across age groups.

INTERPRETATION

Negative psychiatric impacts of COVID-19 on Canadians that include poor access to MH support clearly persisted beyond the first wave, widening pre-existing inequity gaps. This should guide policy makers and clinicians in current and future prioritization efforts.

Prevalence of post-COVID symptoms of obsessive-compulsive disorder in Saudi Arabia

OBJECTIVES

To determine the prevalence of Obsessive-Compulsive Disorder (OCD) symptoms in patients who have survived COVID-19.

METHODS

The study used an observational cross-sectional design between July and October 2021. The target population was adult patients who had confirmed COVID-19 infection prior to joining the study, OCD symptoms were assessed using the Arabic OCD scale created by Abohendy and colleagues, which included 83 questions covering 12 different domains and was administired online.

RESULTS

A total of 356 patients were included in the analysis. Approximately 9.0% and 1.7% of the patients had a history of psychiatric disease and OCD diagnosis (respectively). The total symptom score was 32.8%. The most frequently reported domains were rumination of ideas (55.5%), re-checking compulsions (37.0%), and slowness (34.0%), while the least frequently reported domains included obsessive impulses (26.3%), obsessive images (26.5%), and religious compulsions (26.8%). Unlike other domains, the purity and cleanliness compulsions scores were significantly higher than the scale reference population. A higher total symptom score was observed in psychiatric patients (p=0.004) and, to a lesser extent, in OCD patients (p=0.250).

CONCLUSION

Overall, OCD symptoms, including cleanliness and fear of disease obsessions, tend to be higher in psychiatric and OCD patients, these findings are valuable for future studies.

Development of the COVID-19-Specific Obsessive Compulsive Symptoms Scale with Various Validity and Reliability Proofs

The COVID-19 epidemic, which spread rapidly around the world, has had a significant negative impact on mental health. Obsessive-compulsive disorder (OCD) issues are among the main mental health effects of COVID-19. The purpose of this study is to develop a brief measurement tool that reliably and validly measures obsessive-compulsive (OC) symptoms in people with COVID-19. A total of 483 people took part in the research online. Individuals with aberrant item scores were excluded, and a series of validity and reliability analyses were performed to determine the psychometric properties of the COVID-19-specific obsessive compulsive symptoms scale (C19-OCS). C19-OCS was found to be a valid and reliable measure for assessing OC symptoms in relation to COVID-19. Mental health professionals could use C19-OCS to develop evidence-based intervention strategies and programs.

PTSD trajectories across different mental disorders in the second year of the COVID-19 pandemic in Italy: a naturalistic, longitudinal, multicenter study

The potentially traumatic impact of the COVID-19 pandemic in subjects with pre-existing mental disorders is still unclear, especially regarding its long-term consequences. The aim of this study was to prospectively assess post-traumatic stress disorder (PTSD) and post-traumatic stress symptoms (PTSS) in patients with mental disorders, during the 3rd wave of the infection (T0, March-April 2021) while strict containment measures were applied in Italy, and after 3 months (T1, June-July 2021), with reduced restrictive measures. A total sample of 527 subjects, with different DSM-5 diagnoses, was consecutively enrolled at nine Italian psychiatric outpatient services. Assessments at T0 included: the Trauma and Loss Spectrum-Self Report (TALS-SR), the Impact of Event Scale-Revised (IES-R) and the Work and Social Adjustment Scale (WSAS). These two latter were repeated at T1. Results showed that at T0, 43.6% of the sample reported symptoms of PTSD, with females (p = .004), younger subjects (p = .011), unemployed/students (p = .011), and living with their parental families (p = .017), resulting more affected. Differences in PTSD rates emerged across diagnostic groups ranging from 10% in patients with psychoses up to 59% in those with feeding and eating disorders. An improvement at T1 emerged in all diagnostic groups for the IES-R scores, while WSAS scores improved only in subjects with mood disorders. In conclusions, subjects with mental disorders presented relevant rates of PTSD and PTSS at 1-year into the pandemic. Further long-term studies are needed to follow-up the course of pandemic traumatic burden especially in patients with severe mental disorders.

COVID-19 vaccination coverage among patients with psychiatric disorders in China during the pandemic: a cross-sectional study

BACKGROUND

To investigate the Coronavirus Disease 2019 (COVID-19) vaccination coverage and the influential factors of vaccination among patients with mental disorders, we conducted a cross-sectional study in China.

METHOD

The anonymous questionnaires including demographic data, vaccination status, intention to be vaccinated and its reasons were collected in the Second Xiangya Hospital, one of the biggest four psychiatric centers in China. Mental health of these participants were measured by the Patient Health Questionnaire (PHQ-9) and the Generalized Anxiety Disorder-7 items (GAD-7). The influential factors associated with vaccination status were analyzed by Fisher exact tests and binary logistical analysis.

RESULT

1328 patients and 922 family members completed the survey. The vaccination rate of patients included was 69.4%, whereas 85.5% patients were willing to be vaccinated. Being hospitalized (aOR 0.41, 95% CI:0.27-0.60), suffering from schizophrenia (aOR 0.38, 95% CI: 0.19-0.75) and secondary school educational background (aOR 0.58, 95% CI: 0.37-0.93) were significantly associated with less likelihood to get vaccinated. Uptaking vaccines could reduce depressive (aOR 0.63, 95% CI: 0.41-0.98) or anxious symptoms (aOR 0.40, 95% CI: 0.25-0.63) in these patients for a short period.

CONCLUSION

Further COVID-19 immunization programme should prioritize hospitalized psychiatric patients and schizophrenic patients since their demands for vaccination had been partly ignored during the current inoculation.

Changes in contamination-related obsessions and compulsions during the COVID-19 pandemic: A Norwegian longitudinal study

BACKGROUND

Early stages of the COVID-19 pandemic have been associated with increasing obsessive-compulsive symptoms (OCS), but less is known regarding these symptoms' long-term trajectories. The aim of this study was to examine changes in contamination-related OCS in the Norwegian public during early and late stages of the pandemic, as well as characteristics that might be associated with these changes.

METHODS

In a longitudinal online survey, 12 580 participants completed self-report questionnaires in April 2020, including a retrospective assessment of contamination-related OCS severity (DOCS-SF) prior to COVID-19. In December 2020, 3405 (27.1%) of the participants completed the survey again.

RESULTS

In April, participants retrospectively recalled that their contamination-related OCS were lower prior to COVID-19 (d = 1.09). From April to December, symptoms slightly decreased (d = -0.16). The proportion of participants scoring above the clinical cut-off on DOCS-SF (≥16) changed accordingly from 2.4% pre-COVID to 27.8% in April and 24.0% in December. Previous severity of contamination-related OCS and symptoms of distress related to COVID-19 were the most powerful predictors of contamination-related OCS severity during the pandemic.

CONCLUSIONS

Elevated levels of contamination-related OCS were detected at both early and late stages of the pandemic, but the long-term symptom trend seems to be slightly declining.
