Obsessive-compulsive symptoms and the Covid-19 pandemic: A rapid scoping review

From lockdown to Liberation: How inflexible thinking, obsessive-compulsive and affective symptoms shape pandemic adjustment

BACKGROUND

The COVID-19 pandemic significantly disrupted daily life, and the transition to post-pandemic living presented additional psychological challenges. Previous research shows that individuals with obsessive-compulsive traits and pre-existing mental health histories were vulnerable to adjustment difficulties, which appear to be mediated by depression, anxiety, and stress.

AIMS

This study examined the relationship between post-pandemic adjustment and mental health variables in a population-based cohort during the final lifting of COVID-19 restrictions, tracking outcomes over six months to assess causality. The study was pre-registered on the Open Science Framework (https://osf.io/v4c28).

METHOD

A cohort of 343 UK adults was assessed online at baseline, three, and six months. Self-report measures included the Obsessive-Compulsive Inventory-Revised (OCI-R), Compulsive Personality Assessment Scale (CPAS), Depression, Anxiety, and Stress Scale-21 (DASS-21), Post-Pandemic Adjustment Scale (PPAS) and COVID-19 Safety Behaviour Scale. Cognitive flexibility was assessed using the Wisconsin Card Sorting Test (CST: at baseline) and the Intradimensional-Extradimensional Set-Shifting Task (IDED: at 3 months).

RESULTS

Approximately 28 % of participants were identified as poor adjusters. Mediation analysis revealed that obsessive-compulsive symptoms, compulsive personality traits, and a history of mental health disorders predicted post-pandemic adjustment difficulties indirectly via depression, anxiety, and COVID-19 safety behaviours. While we found no evidence that adjustment was linked to cognitive flexibility on the WCST, exploratory analyses showed that poorer adjustment was linked to reversal learning issues on the IDED task.

CONCLUSION

This study replicated our prior findings, identifying obsessive-compulsive symptoms and traits, mental health histories, and cognitive inflexibility as key risk factors for poor post-pandemic adjustment. Moreover, depression, anxiety, and stress mediated these difficulties, suggesting potential markers for identifying at-risk individuals and guiding interventions for future public health crises.

The long-term impact of the covid-19 pandemic on patients with obsessive-compulsive disorder

We investigated how patients with obsessive-compulsive disorder (OCD) were affected by coronavirus disease of 2019 (COVID-19)-related stress over the long term compared to healthy individuals. We explored how the pandemic affected changes in obsessive-compulsive symptoms and their contributing factors. The study included 100 patients with OCD and 100 sex-matched healthy controls whose sociodemographic and clinical information were gathered. Participants in the study were recruited between December 2021 and May 2022 from individuals attending to the outpatient clinics of the University Department of Psychiatry. The Depression Anxiety Stress Scale-21, Perceptions and Attitudes Towards COVID-19 Questionnaire, COVID-19 Compliance with Prevention Measures Scale, and COVID-19 Stress Scale were used in this study. Patients were assessed using the Yale-Brown Obsession Compulsion Scale based on their conditions before and during the pandemic. Patients with OCD perceived COVID-19 disease as more dangerous and contagious (respectively P = .01, P = .01) compared to the controls. Fifty percent of the patients with OCD experienced an increase in symptoms. Disease severity was increased in mild and moderate OCD, while no significant change was found in severe OCD. Perceiving COVID-19 disease as more dangerous (P = .031), COVID-19-related traumatic stress (P = .013), compulsive control (P = .022), xenophobia (P = .005), and COVID-19-related thoughts (P = .008) were more frequent in OCD patients with clinical worsening. In regression analysis, younger age (OR: 0.95, 95% CI (0.91-0.99)) and higher levels of COVID-19-related stress (OR: 1.03 95% CI (1.01-1.05)) are associated with worsening OCD symptoms. Patients with OCD were adversely affected by the COVID-19 pandemic. Close monitoring of patients with OCD during the pandemic is recommended.

How Does the Normalization Process After the COVID-19 Pandemic Affect Patients With Obsessive-Compulsive Disorder? A Longitudinal Study

ABSTRACT

This study aims to investigate the effect of the normalization process after the pandemic on obsessive-compulsive disorder (OCD) patients. During the pandemic period, the Yale-Brown Obsessive Compulsive Scale (Y-BOCS), Padua Inventory-Washington State University Revision, the Fear of COVID-19 Scale (FCV-19S), and an interview form inquiring sociodemographic characteristics were applied to the participant patients with OCD. During the normalization process, the patients were reevaluated after about 1 year. A significant decrease was found in the patients' FCV-19S and PE-WSUR total scores along with all subscale scores as well as the Y-BOCS scores. The FCV-19S was associated with OCD symptoms both during the pandemic and the normalization period. The final FCV-19S scores of patients with a Y-BOCS score of 12 and under were found to be statistically significantly lower than the others. This study shows that OCD symptom severity and fear of COVID-19 decreased with the normalization process. A decrease in pandemic-related stress and fear of COVID-19 with the normalization process may have positively affected OCD patients.

The Impact of COVID-19 on Patients With Obsessive-Compulsive Disorder in Gulf Countries: A Narrative Review

Gulf countries, like other parts of the world, were affected by the coronavirus disease 2019 (COVID-19) pandemic. Along with its biological effects, the pandemic has had serious psychological and social effects. The pandemic-associated general stress and the increased efforts of handwashing and general hygiene might trigger obsessive-compulsive disorder (OCD). The objective of this narrative review was to explore the influence of the COVID-19 pandemic on the prevalence, severity of symptoms, and accessibility of treatment for OCD in Gulf countries. A comprehensive literature search was conducted to review and collect research and/or reports on the prevalence, symptoms, diagnosis, and treatment adaptations and strategies of OCD during the ongoing COVID-19 pandemic in seven Arab Gulf countries. The search spanned from the onset of the crisis in 2020 to 2024. Peer-reviewed articles and reports were sourced from PubMed/Medline and Google Scholar, while abstracts presented at the American Society of Clinical Oncology (ASCO) and the European Society for Medical Oncology (ESMO) congresses were also included in the review. A total of four studies from Saudi Arabia, two from the United Arab Emirates, and two from Qatar were retrieved for analysis. These studies focused on investigating the impact of the pandemic on OCD. Studies from Kuwait, Oman, and Bahrain reported a negative impact of the pandemic on mental health, yet no specific data were provided. The studies highlighted an increased prevalence of OCD symptoms, both in terms of the incidence of new symptoms and the exacerbation of existing pre-pandemic manifestations. Furthermore, individuals with pre-existing psychological disorders or OCD were particularly susceptible to the negative impact of the pandemic. A review of local studies and reports from the Arab Gulf region reveals a striking paucity of research on the impact of the COVID-19 pandemic on OCD. The pandemic has been associated with an increase in the prevalence of OCD, the onset of new symptoms, and the worsening and exacerbation of existing pre-pandemic obsessions and compulsions.

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.

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.

Impact of Benzodiazepines and Illness Duration on Obsessive-Compulsive Disorder during COVID-19 in Italy: Exploring Symptoms' Evolutionary Benefits

Obsessive-compulsive disorder (OCD) is believed to follow a waxing and waning course, often according to environmental stressors. During the COVID-19 pandemic, pre-existing OCD symptoms were reported to increase and to change from checking to washing behaviors, while new-onset symptoms were predominantly of the hoarding type. In the present study, we followed the evolution of OCD symptoms, anxiety, depression, and insights of illness in forty-six OCD patients throughout the pandemic. Clinical measures were collected at four different time points before and during the COVID-19 pandemic in Italy. Within-subject comparisons were used to compare clinical scale scores across time, and correlations were examined between patients' baseline characteristics and changes in clinical scores. We found that all clinical measures increased during the first Italian lockdown with respect to the pre-pandemic values. Anxiety decreased during the temporary elimination of restriction provisions, whereas the severity of OCD symptoms and insight returned to pre-pandemic values during the second mandatory lockdown. These results were observed only in two sub-groups of patients: those taking benzodiazepines and those with shorter illness duration. Our findings suggest the need for additional clinical attention to these specific sub-groups of OCD patients in case of particularly distressing circumstances while pointing to a possible adaptive role of their OCD symptoms when the environment requires a higher care of hygiene and an extraordinary supply of essential resources.

A closer look: obsessive-compulsive symptoms among intern nurses amidst COVID-19 pandemic

BACKGROUND

The distinctive circumstances and socio-cultural context in Egypt make it crucial to explore the psychological well-being of intern nurses amid the COVID-19 pandemic, with a specific focus on obsessive-compulsive symptoms. This study aimed to investigate the influence of fear of COVID-19 on obsessive-compulsive symptoms among intern nurses.

METHODS

A cross-sectional survey involving 375 randomly recruited intern nurses was conducted. Data collected included the Fear of COVID-19 Scale and the Short Version of the Arabic Obsessive-Compulsive Scale.

RESULTS

A significant relationship was found between the fear of COVID-19 and the severity of obsessive-compulsive symptoms among the participants (r = 0.472, p = 0.000). A stepwise regression analysis indicated that the fear of COVID-19, living in urban regions, frequency of COVID-19 infection, and increased number of infected family members may contribute to the severity of Obsessive-Compulsive Symptoms with adjusted R2 value = 27.5%.

CONCLUSION

The findings suggest that the COVID-19 pandemic has had significant psychological impacts on newly qualified nurses during their internship training period, including the manifestation of mental health symptoms such as Obsessive-Compulsive Symptoms. It was observed that urban residents, intern nurses with recurrent COVID-19 infections, and those with more infected family members exhibited a higher severity of OCS. These findings underscore the need for further research to investigate additional factors that may influence OCS severity.

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.

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.

Death Anxiety in Obsessive-Compulsive Disorders

Objective: Death anxiety has long been attributed a role as a psychopathologically decisive factor in the development of mental illnesses such as obsessive-compulsive disorder (OCD). For example, patients with washing compulsions associate their behavior with a fear of life-threatening diseases or patients with control compulsions report that the constant checking is driven by the fear of fatal or deadly consequences for the occupants.Method: The Bochum Questionnaire to Assess Death Anxiety and Attitudes Towards Death (BOFRETTA) was administered to 31 patients with OCD and 31 healthy volunteers within a semi-structured interview using broad psychometry.Results: OCD patients showed increased death anxiety and negative attitute to death in comparison to healthy volunteers. A significant correlation was found between BOFRETTA-anxiety and the currently present religious obsessive thoughts.Conclusions: Our investigation provides further findings on the role of death anxiety and the problematic attitude towards death in OCD patients.

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.

Mind-Wandering and Its Relationship With Psychological Wellbeing and Obsessive-Compulsive Symptomatology in the Context of Covid-19

Mind-wandering (MW) as a research topic has received considerable attention over the last several decades. The recent differentiation between spontaneous and deliberate MW has suggested a particular effect of the former on psychopathology; in that increased spontaneous MW may precede mental illness. The present study sought to explore MW as a potential contributing factor to poor mental health in the context of the Covid-19 pandemic. More specifically, we sought to determine firstly, whether the effects of MW frequency, type and content on subjective psychological wellbeing was consistent with previous findings after controlling for the impacts of Covid-related stress. Secondly, previous research has demonstrated an effect of both Covid-stress and spontaneous MW on the experience of obsessive-compulsive symptomatology (OCS), and so the present study explored this relationship further by assessing whether Covid-stress mediated the relationship between spontaneous MW and OCS. Participants completed measures of MW, OCS and psychological wellbeing through an online questionnaire. The results indicated that increased spontaneous MW was indicative of both poorer subjective psychological wellbeing and OCS, with Covid-stress partially mediating the relationship between spontaneous MW and OCS. Our findings provide further support for the adverse effect of unintentional MW on psychological wellbeing, as well as for the differentiation between both forms of the cognitive phenomenon. Additionally, they provide an important insight into one of the factors that may have preceded poor mental health among the Irish population during Covid-19. Future research may build upon the present study by exploring similar relationships among clinical populations.

Life-threatening obsessive-compulsive disorder precipitated by the COVID-19 pandemic in an adolescent

The COVID-19 pandemic starting in 2020 has had massive mental health consequences worldwide. It has caused generalised fear and anxiety about catching, spreading and suffering from the virus. This article describes a fictionalised patient's presentation of life-threatening obsessive-compulsive disorder (OCD) associated with fears of catching COVID-19. The fears resulted in refusal to eat and drink, with subsequent weight loss that required paediatric admission. The scenario portrays the association between COVID-19 and life-threatening OCD symptoms and goes on to illustrate the patient's good response to standard OCD treatments.

A pilot study of experiencing racial microaggressions, obsessive-compulsive symptoms, and the role of psychological flexibility

BACKGROUND

Experiencing racial microaggressions has clear effects on physical and psychological health, including obsessive-compulsive disorder symptoms (OCS). More research is needed to examine this link. Psychological flexibility is an important process to examine in this work.

AIMS

This study aimed to examine if, while controlling for depression and anxiety, experiences of microaggressions and psychological flexibility helped explain OCD symptoms within a university-affiliated sample (undergraduate, graduate and law students). This was a pilot exploration of the relationships across themes.

METHOD

Initial baseline data from a longitudinal study of psychological flexibility, OCD symptoms, depression, anxiety and experience of microaggressions was utilized. Correlations and regressions were utilized to examine which OCD symptom dimensions were associated with experiencing racial microaggressions in addition to anxiety and depression, and the added role of psychological flexibility was examined.

RESULTS

OCD symptoms, experiences of microaggressions and psychological flexibility were correlated. Experiences of racial microaggressions explained responsibility for harm and contamination OCD symptoms above and beyond psychological distress. Exploratory results support the relevance of psychological flexibility.

CONCLUSION

Results support other work that experiences of racial microaggressions help explain OCS and they add some support for psychological flexibility as a relevant risk or protective factor for mental health in marginalized populations. These topics should be studied longitudinally with continued consideration of all OCD themes, larger sample sizes, intersecting identities, clinical samples, and continued exploration of psychological flexibility and mindfulness and values-based treatments.

Mental health across two years of the COVID-19 pandemic: a 5-wave longitudinal study in Germany

The COVID-19 pandemic has been negatively associated with mental health. However, little is known about the temporal dynamics of mental health in the longer term of the pandemic. We aimed to investigate symptom levels and changes of depression, anxiety, posttraumatic stress, and loneliness spanning two years of the pandemic; and to examine associated risk factors. This five-wave, longitudinal online study from May 2020 to April 2022 included 636 adults (Mage = 39.5 years, SD = 16.11; 84.1% female) from the German general population who completed the international COVID-19 Mental Health Survey. Symptoms of anxiety (Generalized Anxiety Disorder-7; GAD-7), depression (Patient Health Questionnaire-9; PHQ-9), posttraumatic stress (PTSD Checklist for DSM-5; PCL-5), and loneliness ("Do you feel lonely?") were assessed using mixed-effects models. Associations with anxiety and depressive symptoms were examined with having children, student status, financial worries, contamination fear, and loneliness. PHQ-9, GAD-7, PCL-5, and loneliness scores overall decreased throughout the two-year period of the pandemic but exhibited an increase during two national lockdowns. Controlled for significant associations with female gender and younger age, increased PHQ-9 and GAD-7 scores were associated with contamination fear, financial worries, and loneliness. No associations were found with having children and student status. Symptoms of depression, anxiety, posttraumatic stress, and loneliness decreased over time but varied along with the dynamics of the pandemic. Longitudinal monitoring of mental health in vulnerable subgroups is required, especially those of younger age, females, and the financially insecure.

Astrocytes and the Psychiatric Sequelae of COVID-19: What We Learned from the Pandemic

COVID-19, initially regarded as specific lung disease, exhibits an extremely broad spectrum of symptoms. Extrapulmonary manifestations of the disease also include important neuropsychiatric symptoms with atypical characteristics. Are these disturbances linked to stress accompanying every systemic infection, or are due to specific neurobiological changes associated with COVID-19? Evidence accumulated so far indicates that the pathophysiology of COVID-19 is characterized by systemic inflammation, hypoxia resulting from respiratory failure, and neuroinflammation (either due to viral neurotropism or in response to cytokine storm), all affecting the brain. It is reasonable to hypothesize that all these events may initiate or worsen psychiatric and cognitive disorders. Damage to the brain triggers a specific type of reactive response mounted by neuroglia cells, in particular by astrocytes which are the homeostatic cell par excellence. Astrocytes undergo complex morphological, biochemical, and functional remodeling aimed at mobilizing the regenerative potential of the central nervous system. If the brain is not directly damaged, resolution of systemic pathology usually results in restoration of the physiological homeostatic status of neuroglial cells. The completeness and dynamics of this process in pathological conditions remain largely unknown. In a subset of patients, glial cells could fail to recover after infection thus promoting the onset and progression of COVID-19-related neuropsychiatric diseases. There is evidence from post-mortem examinations of the brains of COVID-19 patients of alterations in both astrocytes and microglia. In conclusion, COVID-19 activates a huge reactive response of glial cells, that physiologically act as the main controller of the inflammatory, protective and regenerative events. However, in some patients the restoration of glial physiological state does not occur, thus compromising glial function and ultimately resulting in homeostatic failure underlying a set of specific neuropsychiatric symptoms related to COVID-19.

Validation of the Collaborative Outcomes study on Health and Functioning during Infection Times (COH-FIT) questionnaire for adults

BACKGROUND

The Collaborative Outcome study on Health and Functioning during Infection Times (COH-FIT; www.coh-fit.com) is an anonymous and global online survey measuring health and functioning during the COVID-19 pandemic. The aim of this study was to test concurrently the validity of COH-FIT items and the internal validity of the co-primary outcome, a composite psychopathology "P-score".

METHODS

The COH-FIT survey has been translated into 30 languages (two blind forward-translations, consensus, one independent English back-translation, final harmonization). To measure mental health, 1-4 items ("COH-FIT items") were extracted from validated questionnaires (e.g. Patient Health Questionnaire 9). COH-FIT items measured anxiety, depressive, post-traumatic, obsessive-compulsive, bipolar and psychotic symptoms, as well as stress, sleep and concentration. COH-FIT Items which correlated r ≥ 0.5 with validated companion questionnaires, were initially retained. A P-score factor structure was then identified from these items using exploratory factor analysis (EFA) and confirmatory factor analyses (CFA) on data split into training and validation sets. Consistency of results across languages, gender and age was assessed.

RESULTS

From >150,000 adult responses by May 6th, 2022, a subset of 22,456 completed both COH-FIT items and validated questionnaires. Concurrent validity was consistently demonstrated across different languages for COH-FIT items. CFA confirmed EFA results of five first-order factors (anxiety, depression, post-traumatic, psychotic, psychophysiologic symptoms) and revealed a single second-order factor P-score, with high internal reliability (ω = 0.95). Factor structure was consistent across age and sex.

CONCLUSIONS

COH-FIT is a valid instrument to globally measure mental health during infection times. The P-score is a valid measure of multidimensional mental health.

Development of a protocol for videoconferencing-based exposure and response prevention treatment of obsessive-compulsive disorder during the COVID-19 pandemic

BACKGROUND

The existing literature indicates that psychotherapeutic treatment, especially exposure and response prevention (ERP) is efficacious in treating obsessive-compulsive disorder (OCD). The coronavirus disease 2019 pandemic adversely impacted many patients with OCD and disrupted their usual treatment. Moreover, the pandemic forced a global switch to telemental health (TMH) services to maintain the standards and continuity of care. Consequently, clinicians are increasingly using TMH-based psychotherapeutic treatments to treat OCD. However, several challenges have made it difficult for them to implement these treatments in the changed circumstances imposed by the pandemic.

AIM

To describe the formulation, implementation, feasibility, and usefulness of videoconferencing-based ERP (VC-ERP) treatment for OCD during the coronavirus disease 2019 pandemic.

METHODS

This prospective, observational study was conducted in the psychiatric unit of a multi-specialty hospital in north India over 12 mo (July 2020-June 2021). All patients with OCD were assessed using the home-based TMH services of the department. The VC-ERP protocol for OCD was the outcome of weekly Zoom meetings with a group of clinicians involved in administering the treatment. After a systematic evaluation of the available treatment options, an initial protocol for delivering VC-ERP was developed. Guidelines for clinicians and educational materials for patients and their families were prepared. The protocol was implemented among patients with OCD attending the TMH services, and their progress was monitored. The weekly meetings were used to upgrade the protocol to meet the needs of all stakeholders. Feasibility and efficacy outcomes were examined.

RESULTS

All patients were diagnosed with OCD as a primary or a comorbid condition according to the International Classification of Diseases, 10th version criteria. Out of 115 patients who attended the services during the study period, 37 were excluded from the final analysis. Of the remaining 78 patients, VC-ERP was initiated in 43 patients. Six patients dropped out, and three were hospitalized for inpatient ERP. Eleven patients have completed the full VC-ERP treatment. One patient completed the psychoeducation part of the protocol. VC-ERP is ongoing in 22 patients. The protocol for VC-ERP treatment was developed and upgraded online. A large proportion of the eligible patients (n = 34/43; 79%) actively engaged in the VC-ERP treatment. Drop-out rates were low (n = 6/43; 14%). Satisfaction with the treatment was adequate among patients, caregivers, and clinicians. Apart from hospitalization in 3 patients, there were no other adverse events. Hybrid care and stepped care approaches could be incorporated into the VC-ERP protocol. Therefore, the feasibility of VC-ERP treatment in terms of operational viability, service utilization, service engagement, need for additional in-person services, frequency of adverse events, and user satisfaction was adequate. The VC-ERP treatment was found to be efficacious in the 11 patients who had completed the full treatment. Significant reductions in symptoms and maintenance of treatment gains on follow-up were observed.

CONCLUSION

This study provided preliminary evidence for the feasibility and usefulness of VC-ERP in the treatment of OCD. The results suggest that VC-ERP can be a useful option in resource-constrained settings.

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.

A Machine Learning-Based Risk Prediction Model for Post-Traumatic Stress Disorder during the COVID-19 Pandemic

Background and Objectives: The COVID-19 pandemic has caused global public panic, leading to severe mental illnesses, such as post-traumatic stress disorder (PTSD). This study aimed to establish a risk prediction model of PTSD based on a machine learning algorithm to provide a basis for the extensive assessment and prediction of the PTSD risk status in adults during a pandemic. Materials and Methods: Model indexes were screened based on the cognitive-phenomenological-transactional (CPT) theoretical model. During the study period (1 March to 15 March 2020), 2067 Chinese residents were recruited using Research Electronic Data Capture (REDCap). Socio-demographic characteristics, PTSD, depression, anxiety, social support, general self-efficacy, coping style, and other indicators were collected in order to establish a neural network model to predict and evaluate the risk of PTSD. Results: The research findings showed that 368 of the 2067 participants (17.8%) developed PTSD. The model correctly predicted 90.0% (262) of the outcomes. Receiver operating characteristic (ROC) curves and their associated area under the ROC curve (AUC) values suggested that the prediction model possessed an accurate discrimination ability. In addition, depression, anxiety, age, coping style, whether the participants had seen a doctor during the COVID-19 quarantine period, and self-efficacy were important indexes. Conclusions: The high prediction accuracy of the model, constructed based on a machine learning algorithm, indicates its applicability in screening the public mental health status during the COVID-19 pandemic quickly and effectively. This model could also predict and identify high-risk groups early to prevent the worsening of PTSD symptoms.

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.

Adverse Childhood Events, Post-Traumatic Stress Disorder, Infectious Encephalopathies and Immune-Mediated Disease

Adverse Childhood Events (ACE), Post-Traumatic Stress Disorder (PTSD), and infectious encephalopathies are associated with immune-mediated diseases. Data supporting this are reviewed, and an integrated hypothesis is provided. All three can be associated with intrusive symptoms and temporal lobe pathology. ACE and PTSD are accompanied by an impaired mental capacity to differentiate external danger vs. safety. Infectious encephalopathies are accompanied by a failure of adaptive immunity and an impaired immune capacity to differentiate internal danger vs. safety. All three conditions are associated with impairments to differentiate danger vs. safety and adapt effectively. There are reciprocal interactions between ACE, PTSD, and infectious encephalopathies with accompanying persistent immune activation. This is associated with immune dysregulation, chronic hyperarousal, activation of the stress response, and impairments of the fear recognition and response neural circuits, hypothalamic–pituitary–adrenal axis, amygdala, and hippocampus. The pathophysiological processes can result in a broad spectrum of chronic neuropsychiatric and somatic symptoms and diseases. Understanding the psychodynamic, neurological, neuroimmune, inflammatory and autoimmune components of this interactive process expands the effective treatment opportunities.

Hand Washing: When Ritual Behavior Protects! Obsessive-Compulsive Symptoms in Young People during the COVID-19 Pandemic: A Narrative Review

The Coronavirus Disease 2019 (COVID-19) pandemic had a profound impact on the lifestyles and mental health of young people. It has been hypothesized that the focus on hygiene and the fear of contamination/infection during the pandemic may have exacerbated obsessive–compulsive (OC) symptoms in this population. OC symptoms are widespread in the general population, with varying degrees of intensity. At their most extreme, they manifest in obsessive–compulsive disorder (OCD), which is characterized by obsessive thoughts and compulsive behaviors. The present narrative review aimed at evaluating the relationship between the COVID-19 pandemic and OCD and OC symptoms in young people, especially children and adolescents with and without OCD, focusing on vulnerability and risk factors and the impact of lockdown measures. Of the six studies identified, four examined clinical samples diagnosed with OCD and two looked at community-based adolescent samples. Five of the six studies found that OC symptoms increased during the pandemic. Additionally, vulnerability to anxiety may constitute a risk condition and the lockdown measures and personal stressful life events can constitute potential triggers of OC symptoms, while ongoing treatment for OCD had a protective effect. The results suggest that, during the COVID-19 pandemic, obsessive and compulsive behavior (e.g., hand washing) in young people at the greatest risk should be monitored, and the intervention of mental health services should be maintained. More research is needed in this area.

The impact of the COVID-19 pandemic on the development of anxiety disorders - a literature review

Introduction: The COVID-19 is a disease caused by the SARS-CoV-2 virus. A number of psychological symptoms have been identified in people living during the COVID-19 pandemic. Most of them are associated with widely understood anxiety disorders, which have always been a significant problem for mental health.

Materials and methods: The available literature was reviewed on the Pubmed platform and from other sources. The analysis included original studies, reviews, meta-analyzes and internet sources. The aim of the study was to review the literature on the relationship between the COVID-19 pandemic and the occurrence and severity of symptoms of anxiety disorders.

Results: The studies conducted so far show that the COVID-19 pandemic has had a significant impact on the mental state of people around the world, especially in the area of anxiety disorders. Many studies indicate an increase in the prevalence of symptoms of generalized anxiety disorder. Research also indicates a greater incidence of post-traumatic stress disorder and panic disorder in society. Symptoms of somatization were also quite often observed in patients. However, the state of published studies indicates that the pandemic did not significantly affect the severity of symptoms associated with social phobia. In the context of phobic disorders, a new type has been formulated: COVID-19-related phobia.

Conclusions: The conducted literature review shows that the current COVID-19 pandemic is associated with an increase in the prevalence of symptoms of anxiety disorders in the general population. The multifaceted nature of the issue of anxiety disorders in the COVID-19 pandemic clearly indicates the need to continue research in this area.

COVID-19 and obsessive-compulsive symptoms in a large multi-site college sample

The COVID-19 pandemic poses unique risks to college students' mental health, and specifically to symptoms of obsessive-compulsive disorder (OCD). To better understand the relationship between COVID-19 impact and OC symptoms in this population, six colleges from across the US administered a battery of questionnaires and an emotion differentiation paradigm to eligible students (N = 841). We examined whether degree of pandemic-related disruption was associated with OC severity, and if so, whether this relationship was explained by trait (poor emotion regulation and differentiation) and state risk factors (poor sleep quality, less exercise frequency, less social support, thwarted sense of belongingness, and greater loneliness). Results indicated that the positive relationship between COVID-19 impact and OC severity was mediated by trait emotion-related processes (e.g., emotion regulation and differentiation), but no state risk factors emerged as significant mediators. Our findings contribute to the literature demonstrating a significant relationship between COVID-19 impact and OC severity, and highlight that emotion regulation difficulties may help explain this association. Our findings can inform evidence-based interventions on college campuses; however, the cross-sectional design precludes causal inferences. Future research should evaluate these relationships longitudinally and incorporate other psychosocial factors that may operate as mechanisms.

A brief course of digitally delivered cognitive behavioural therapy for the treatment of blood contamination-based obsessive-compulsive disorder: a structured case report

The lifetime prevalence of OCD in the UK is estimated to be between 1 in 100 and 1 in every 50 people. It is therefore necessary to explore innovations in practice to expand the reach of the gold standard therapeutic approaches of exposure with response prevention (ERP) and cognitive behavioural therapy (CBT). The COVID-19 pandemic has facilitated such innovations with several services accommodating changes to routine practice by utilising digital platforms to provide videoconference-delivered therapy. Despite a growing evidence base demonstrating efficacy and scope for the use of videoconference-delivered CBT for obsessive-compulsive disorder (OCD), there remains qualitative research collated from clinicians which suggests that a lack of practitioner confidence and a low belief in positive outcomes are barriers to adopting remote therapy practices for clinicians. Therefore, this structured case report describes the assessment, formulation, intervention and outcome of an 11-week videoconference-delivered therapeutic intervention. Reflections are made regarding the use of the digital platform throughout the intervention, alongside the strengths and difficulties of applying videoconference-delivered CBT for OCD.
