How are OCD Patients and Family Members Dealing with the Waxing and Waning Pattern of the COVID-19 Pandemic? Results of a Longitudinal Observational Study

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.

Impact of the COVID-19 pandemic on obsessive-compulsive symptoms in the Swiss general population

Background

In the early stages of the COVID-19 pandemic, mental-health experts called attention to a possible deterioration of obsessive-compulsive symptoms (OCSs). In particular, people suffering from a fear of contamination were considered a vulnerable population.

Aim

The aim of this study was to investigate the change in OCSs from before to during the pandemic within the Swiss general population, and to examine a possible relationship of OCSs to stress and anxiety.

Methods

This cross-sectional study was implemented as an anonymized online survey (N = 3,486). The Obsessive-Compulsive Inventory-Revised (OCI-R) was used to assess global OCS severity (range: 0-72, clinical cut-off > 18) and specific OCS dimensions (range: 0-12) during the second wave of the pandemic and retrospectively for before the pandemic. Participants were asked to report stress and anxiety in the previous 2 weeks before the survey.

Results

Participants reported significantly higher OCI-R total scores during (12.73) compared to before the pandemic (9.04, mean delta increase: 3.69). Significantly more individuals reported an OCI-R total score exceeding the clinical cut-off during (24%) than before the pandemic (13%). OCS severity increased on all symptom dimensions, but was most pronounced on the washing dimension (all with p < 0.001). Self-reported stress and anxiety were weakly associated with differences in severity in total score and symptom dimensions (with R² < 0.1 and p < 0.001).

Conclusion

Our results indicate that the full spectrum of people with OCS should be considered as risk groups for symptom deterioration during a pandemic and when assessing its possible long-term effects of such.

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.

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.
