ABSTRACT
OBJECTIVE: This study addresses the limitations of existing interventions for depression, such as a deficit-oriented focus, overlooking the utilization of positive elements such as nature, and neglecting the incorporation of group effects. The present feasibility study examines FlowVR, a resource-oriented, nature-inspired virtual reality (VR)-based group therapy. Previously tested individually in a pilot study for non-clinical participants, FlowVR has demonstrated positive effects on depressive symptoms. This study assesses the impact and safety of FlowVR in a group setting within a clinical sample using a one-armed study design. METHOD: Forty-two inpatients and day patients with depression were recruited. Before and after the FlowVR intervention period of 4 weeks (two sessions per week), depressive symptoms were assessed (Beck Depression Inventory-II; BDI). Symptomatology (i.e., depressive symptoms), depression-associated variables (i.e., self-efficacy), intervention-specific variables (feeling of flow), and VR-specific variables (simulator sickness) were assessed before and after each session. RESULTS: Linear mixed effect models showed that symptomatology (depression, negative affect, current anxiety), depression-associated constructs (self-efficacy, motivation), and intervention-specific variables (flow) improved over the course of the sessions. No variable deteriorated more in one session compared to any other session. The lasso regression identified five potential predictors for the change in depression (BDI-II), yet these could not be validated in a subsequent linear regression analysis. CONCLUSION: To conclude, FlowVR had the hypothesized positive impact over the course of the sessions, showing, for example, improvements in symptomatology. The sessions have demonstrated safety with no notable deteriorations. Therefore, FlowVR is deemed safe for clinical patients and group settings. However, further research is needed to explore predictors for the change in depression.
ABSTRACT
Identifying components of modularized psychological interventions that contribute to symptom reduction is essential to improving depression treatment. In a secondary analysis of a randomized controlled trial (RCT), session-specific effects of Metacognitive Training-Silver, a group intervention for older adults with depression, were investigated. Thirty-eight older adults with major depressive disorder or dysthymia participated in up to eight sessions of MCT-Silver. A clinical assessment of depressive symptoms (Hamilton Depression Rating Scale) as well as additional interviews and questionnaires administered as part of the RCT were completed at pre- and post-intervention. Depressive symptoms, negative (meta)cognitive beliefs, emotion regulation strategies and attitudes toward aging were assessed pre- and post-session. The rate of change in each variable per module, elevation following the module in which the variable was addressed, and the rate of change post module were examined via linear mixed models. Clinician-rated depressive symptoms were significantly reduced from pre- to post-intervention (Cohens d = 1.31). Self-reported depression and negative mental filter measured within sessions improved significantly over treatment, whereas black-and-white thinking improved after module #3 (Should Statements, All or Nothing Thinking and Acceptance). Module-specific within-session effects were found for overgeneralization (module #1: Mental Filter) and rumination (module #6: Rumination and Social Withdrawal). Improvement in mental filter in module #1 was significantly associated with depression reduction. This study provides initial evidence that MCT-Silver partially meets its aims of reducing depression and specific cognitive variables within and across sessions. Improvement of the instrument used to measure change may improve detection of module-specific effects.Trial registration: NCT03691402.

OBJECTIVE: Cognitive theories emphasize the central role of anger and anger suppression in obsessive-compulsive disorder (OCD). According to these theories, anger suppression is seen as a consequence of OCD, whereas cognitive beliefs, such as an inflated sense of responsibility, are seen as antecedent factors. To extend the findings from cross-sectional studies, the current study investigated the temporal associations between OCD symptoms, an inflated sense of responsibility, and anger suppression. Consistent with cognitive considerations, we hypothesized that OCD symptoms mediate the association between feelings of responsibility and anger suppression. These associations were also explored in patients presenting particularly high checking-related symptoms. Further, the stability of effects beyond controlling for depressive symptoms and medication intake was explored. METHODS: A total of N = 48 patients with OCD (50% female, M = 32.46 [SD = 10.63] years of age) completed measures on obsessive beliefs, OCD symptoms, and anger suppression at three assessment points: before and after a metacognitive intervention as well as at a follow-up 6 months later. Mediation models investigating symptom associations at these three timepoints were conducted. Exploratory analyses investigating these associations in individuals presenting high checking-related symptoms (n = 20) and testing the stability of effects beyond controlling for depressive symptoms and medication intake were conducted. RESULTS: The sense of responsibility did not significantly predict the level of anger suppression. A temporal association between OCD symptoms (as assessed with the self-report measure) and anger suppression could be evidenced, which was stable beyond controlling for depressive symptoms and medication intake. Against the expectations based on cognitive theories, the sense of responsibility did not predict OCD symptoms. No mediating effect of OCD symptoms was found. CONCLUSION: In line with cognitive viewpoints, the present study shows that higher OCD symptoms predict higher levels of anger suppression in a longitudinal design, thereby contributing to the suppression of anger. This effect seems to be independent from depressive symptoms and medication intake. The effect of sense of responsibility on OCD symptoms was less clear and could only be found in the subgroup of patients with OCD and checking-related symptoms, who generally presented higher levels of responsibility. Overall, this is the first study demonstrating temporal associations between OCD symptoms and anger suppression. Acknowledging that anger and anger suppression may be a consequence of OCD symptoms and may also affect aspects of psychotherapy, which can ultimately inform future adjustments to psychotherapeutic treatment.
ABSTRACT
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.
ABSTRACT
BACKGROUND AND OBJECTIVES: Patients with obsessive-compulsive disorder (OCD) have reported higher anger and aggression than healthy individuals in previous studies using explicit measures. However, studies using implicit measures have demonstrated mixed results. The aim of the present study was to investigate implicit aggressiveness in OCD using an approach-avoidance task (AAT). METHODS: Seventy-eight patients with OCD and 37 healthy controls underwent structured clinical interviews and measures of anger, OCD, and depressive symptoms as well as a computerized AAT that included aggressive, peaceful, negative, and positive stimuli. RESULTS: In line with previous studies, patients with OCD reported higher scores on explicit anger. With respect to the implicit measure, repeated measures ANOVAs did not show any differences in mean reaction times for pushing compared to pulling aggressive versus peaceful and negative versus positive words. However, analyses of specific OCD symptom dimensions demonstrated significantly faster reaction times for pulling compared to pushing aggressive words for patients with high scores in the OCD symptom dimensions obsessing and hoarding. LIMITATIONS: Eighty percent of patients with OCD showed psychiatric comorbidities and all were seeking treatment. CONCLUSION: The present study supports previous studies reporting the absence of higher aggressiveness in patients with OCD compared to healthy controls using implicit measures. However, in contrast to previous studies, we found an implicit approach bias towards aggressive self-statements for OCD patients scoring high in the symptom dimensions obsessing and hoarding compared to healthy controls. Future studies should further elucidate putative functional relationships between different OCD symptom dimensions and implicit aggressiveness.

The Metacognitive Training for Depression (D-MCT) is a highly structured group therapy that has been shown to be effective in reducing depressive symptoms. First evidence suggests that need for control represents a mechanism of change. However, more research is needed to evaluate the mode of action of each module and identify predictors of treatment response. Two sequential studies (one naturalistic pilot study [study I, N = 45] and one randomized controlled trial [study II, N = 32]) were conducted to evaluate the session-specific effects and predictors of D-MCT in patients with depression. The D-MCT was conducted over eight weeks, and patients answered a questionnaire on dysfunctional beliefs (e.g., negative filter) and depressive symptoms (e.g., lack of energy, self-esteem) before and after each session. Linear mixed-effects models showed that several dysfunctional beliefs and symptoms improved over the course of the treatment; three modules were able to evoke within-session effects, but no between-session effects were found. The improvement in lack of energy in one module was identified as a relevant predictor in study I via lasso regression but was not replicated in study II. Exploratory analyses revealed further predictors that warrant replication in future studies. The identified predictors were inconclusive when the two studies were compared, which may be explained by the different instruments administered. Even so, the results may be used to revise questionnaires and improve the intervention.

Dysfunctional beliefs are central in the development and maintenance of obsessive-compulsive disorder (OCD) as well as its treatment. Yet, research suggests that not all dysfunctional beliefs are equally important for each of the symptom dimensions of OCD. However, results are inconsistent in that studies contradict each other regarding the associations between specific symptom dimensions and belief domains. The aim of the present study was to clarify which belief domain is specifically associated with which OCD symptom dimension. Results could help to tailor treatments more specifically to the patient's OCD symptom dimension. In- and outpatients with OCD (N = 328; 43.6% male and 56.4% female) filled out questionnaires on symptom dimensions of OCD (Obsessive-Compulsive Inventory Revised) and dysfunctional beliefs (Obsessive Beliefs Questionnaire). A structural equation model analysis was conducted to identify the associations between dysfunctional beliefs and symptom dimensions. Our results showed that perfectionism/intolerance of uncertainty was associated with hoarding and symmetry/ordering, (2) overestimation of threat/inflated responsibility was associated with checking compulsions, and (3) importance of thoughts/control of thoughts was associated with obsessing. These results were largely supported by a backward selection. Our results demonstrated associations of specific dysfunctional beliefs and specific OCD symptom dimensions. However, future studies are necessary to replicate these findings with other measures (e.g., clinician ratings).

BACKGROUND: Adherence to internet-based cognitive-behavioral therapy (iCBT) is often low, possibly reducing its potential. The current study set out to test whether adherence and effects of unguided iCBT for obsessive-compulsive disorder (OCD) could be improved by varying the degree of autonomy in which modules are completed (free choice vs. fixed order). METHODS: We randomized 151 individuals with OCD to either an unguided iCBT with a fixed (iCBTfixed) or a free-choice (iCBTfree+) order of the modules. We assessed participants at baseline (t0), eight weeks (t1), and 16 weeks (t2). Primary outcomes were adherence (utilization time, modules completed) and change in OCD severity (Y-BOCS). Secondary outcomes included depression, self-esteem, and treatment satisfaction. We calculated intent-to-treat (ITT) and complete case (CC) analyses. RESULTS: Analyses showed that both iCBT programs significantly reduced OCD severity. While groups did not differ on the ITT analyses, for the CC analyses, a greater improvement was found in the iCBTfixed in comparison to the iCBTfree+ group regarding OCD severity and quality of life, with medium effect sizes from t0 to t1 (ηp2 = 0.067-0.077). Time of utilization and number of modules completed did not differ between groups. LIMITATIONS: No placebo control group, short follow-up period, self-report assessment. CONCLUSIONS: iCBT is effective in improving OCD. Despite similar adherence in the fixed versus the free-choice module order, the study offers tentative evidence that a fixed order of content is associated with better effects. More research on the effects of adherence on outcome is necessary.

Internet-based cognitive-behavioural interventions (iCBT) are a valuable alternative to face-to-face psychotherapy. An unguided iCBT program has shown to be efficacious for patients with obsessive-compulsive disorder (OCD). However, the modules' mode of action is not well understood, which is the objective of the present study. Twenty-five patients with OCD who participated at the iCBT program for 8 weeks answered a questionnaire on their self-efficacy, motivation, expected increase in health competence and experiential avoidance before and after each module and were included in the present analyses. Linear mixed-effects models demonstrated that patients' expected increase in health competence improved over the course of the treatment. No within-module-specific effect was found. The iCBT program was able to improve patients' expected health competence. However, all other variables did not change. The iCBT program should be revised by focusing more strongly on the integration of the content to reduce experiential avoidance and to improve motivation.

It is essential to understand the effects of specific therapy elements (i.e., mechanisms of change) to optimize the efficacy of available treatments. There are, however, existing challenges in the assessment and analysis of constructs of interest. The present study aims to improve research on the effects of specific therapy elements using the example of the Metacognitive Training for Obsessive-Compulsive Disorder (MCT-OCD) intervention. Specifically, we introduce an innovative analytical method to identify predictors of treatment outcome and expand the assessment of common factors (e.g., coping expectations). A sample of 50 day- and inpatients with OCD was assessed before and after participation in an 8-week MCT-OCD programme. We investigated within-session change in scores on revised questionnaires administered before and after each session. Linear mixed models (for session-effects) and lasso regression (for prediction analyses) were used to analyse data. The revised assessments and data analyses showed greater improvement in dysfunctional (meta-)cognitive beliefs over the time of the intervention and within sessions compared to previous MCT-OCD studies. Some predictors, for example, improvement in coping expectation after the module on overestimation of threat for treatment outcome, were identified. The present study contributed to a better understanding of how to assess and analyse data of a modular intervention and demonstrated the strengths and weaknesses of different analytic approaches. Moreover, the analyses provided a deeper understanding of the specific effects and mechanisms of change of MCT-OCD modules, which can be refined and examined in future studies.

INTRODUCTION: Technology-supported exposure and response prevention (ERP) for patients with obsessive-compulsive disorder (OCD) as tested in clinical research, holds promise but also has limitations. The present study aims to overcome these limitations by using mixed reality for ERP (MERP). The objectives of this pilot study were to evaluate the safety, feasibility, and acceptance of MERP and to identify possible obstacles. METHODS: Twenty inpatients with contamination-related OCD were recruited and randomized to two conditions: MERP (six sessions in 3 weeks) and care as usual treatment. Patients were assessed before treatment (baseline), after the 3-week intervention period (post), as well as 3 months after post assessment (follow-up) regarding symptomatology (Y-BOCS). RESULTS: Results showed a similar reduction in symptomatology in both groups from baseline to post. Regarding safety, no clinically significant deterioration was detected in the MERP group. Patients' evaluation of the MERP was heterogeneous. The qualitative feedback provided helpful indications for further development of the software. Sense of presence was below the midpoint of the scales. CONCLUSION: This is the first study evaluating a MERP for patients with OCD that shows cautious evidence for the acceptance and safety of MERP. The results of the subjective evaluation suggest revisions of the software.

Many patients with obsessive-compulsive disorder (OCD) do not receive cognitive behavioral therapy with exposure and response prevention (first line treatment for OCD), for example, due to patients' fear of the exposure and reservations of the therapists. Technology-supported exposure (e.g., exposure therapy with response prevention in mixed reality [MERP]) for patients with OCD may help to overcome this obstacle. Building upon findings of our pilot study objectives of this study are to evaluate the efficacy, expectations of treatment success, feasibility, and acceptance of MERP as well as to identify possible limitations. In total, 64 outpatients with contamination-related OCD will be recruited and randomized to one of two conditions: MERP (six sessions in six weeks) and self-guided exposure therapy (six exercises in six weeks). Participants will be assessed before (baseline), after the six-week intervention period (post), as well as three months after post assessment (follow-up) regarding symptomatology (Yale-Brown Obsessive Compulsive Scale; Y-BOCS), their subjective evaluation of MERP (acceptance) and sense of presence. The planned study is the first to investigate MERP in patients with OCD.

OBJECTIVE: Explicitly addressing suicidality in group therapy is often avoided due to the fear of contagion effects. However, there is some evidence that this fear is not valid. Therefore, the present study aims at contributing to this question by investigating the session-specific effects of two modules on suicidality that are part of the Metacognitive Training for Depression (D-MCT/S). METHODS: Forty-four patients with depression participated in the two modules on suicidality of the D-MCT/S. Before and after each group session, patients filled out a questionnaire asking for symptoms of suicidality, associated cognitions (e.g., hopelessness), and associated emotions (e.g., anger). Data were analyzed by linear mixed-effect models. RESULTS: Approximately 84% of the patients had experienced lifetime suicidal ideation. No within- or between-session effects were found for the modules on suicidality. Sample size was large enough to find small to medium effects (within-session analyses) and medium to large effects (between-session analyses). CONCLUSION: The modules on suicidality did not specifically change suicidal symptoms or associated cognitions and emotions immediately or by the next session. Most importantly, our results disconfirm evidence on deterioration when suicidality is addressed in a highly structured group setting. Whether the current findings also apply to other forms of group therapies needs to be investigated in future studies. HIGHLIGHTSSession-specific investigations allow a thoroughly examination of an interventionMetacognitive Training for Depression showed no contagion effect on suicidality.

Exposure therapy in virtual reality is successful in treating anxiety disorders. Studies on exposure and response prevention in virtual reality (VERP) in obsessive-compulsive disorder (OCD) are rare, and it is unclear whether distress associated with other emotions than anxiety (e.g., disgust) can be evoked. The present study aimed to investigate whether distress can be induced during VERP in patients with contamination-related OCD (C-OCD) and a primary feeling of disgust. We treated eight female patients with C-OCD with the primary emotion of disgust over six weeks with VERP and assessed their OC symptoms before and after the intervention period with the Y-BOCS. We measured subjective units of distress (SUD), heart rate and skin conductivity (arousal), sense of presence, and simulator sickness during four consecutive exposure sessions. VERP was able to induce distress and arousal. The qualitative feedback was heterogeneous and sense of presence moderate. Patients' OC symptoms reduced over the treatment period with medium to large effect sizes, but only two patients were considered responders; two patients discontinued treatment due to lack of treatment success. Although VERP was able to induce distress and arousal associated with disgust and evoked a moderate sense of presence, the low rate of symptom reduction diminishes the positive results. Possible reasons for the heterogeneous results and implications are discussed. Trial registration: German Registry for Clinical Studies (DRKS00016929), 10.04.2019.

OBJECTIVE: Unrealistic pessimism (UP) is an aspect of overestimation of threat (OET) that has been associated with obsessive-compulsive disorder/symptoms (OCD/OCS). During the COVID-19 pandemic, UP may have played an important role in the course of OCD. To investigate the relationship, we conducted two longitudinal studies assuming that higher UP predicts an increase in OCS. METHOD: In Study 1, we investigated UP in the general population (N = 1,184) at the start of the pandemic asking about overall vulnerability to infection with SARS-CoV-2 and UP regarding infection and outcome of severe illness. Further, OCS status (OCS+/-) was assessed at the start of the pandemic and 3 months later. In Study 2, we investigated UP in individuals with OCD (N = 268) regarding the likelihood of getting infected, recovering, or dying from an infection with SARS-CoV-2 at the start of the pandemic and re-assessed OCS 3 months later. RESULTS: In Study 1, UP was higher in the OCS+ compared to the OCS- group, and estimates of a higher overall vulnerability for an infection predicted a decrease in OCS over time. UP regarding severe illness predicted an increase in symptoms over time. In Study 2, UP was found for a recovery and death after an infection with SARS-CoV-2, but not for infection itself. CONCLUSIONS: Exaggeration of one's personal vulnerability rather than OET per se seems pivotal in OCD, with UP being associated with OCD/OCS+ as well as a more negative course of symptomatology over the pandemic in a nonclinical sample. PRACTITIONER POINTS: Unrealistic optimism, a bias common in healthy individuals, is thought to be a coping mechanism promoting well-being in the face of danger or uncertainty. The current study extends findings that its inversion, unrealistic pessimism, may play an important role in obsessive-compulsive disorder and may also be involved in the development of the disorder. This study highlights the importance that prevention programs during a pandemic should include targeting unrealistic pessimism.

Although exposure and response prevention (ERP) is considered the gold standard for the treatment of obsessive-compulsive disorder (OCD), it is rarely used in clinical practice. Therapists' beliefs about ERP affect its utilization, as previous research suggests, but the role of therapists' cognitive biases is unclear. In particular, susceptibility to thought-action fusion (TAF) may be related to the underutilization of ERP in OCD. Therapists (N = 353) were divided into those recommending (ERP+, n = 228) and not recommending ERP (ERP-, n = 125) as treatment for an OCD case example. TAF in therapists was assessed using behavioral and self-report measures (TAFS). TAF was higher in the ERP- than the ERP+ group, with a small to moderate effect size (0.2 ≤ d ≤ 0.4). ERP- therapists showed more avoidance and neutralizing behavior and a stronger emotional response than the ERP+ therapists during the experimental task. Moreover, higher TAF as measured by the TAFS was associated at a small magnitude with lower likelihood of using ERP in the therapists' actual clinical practices. Therapists' cognitive biases should be addressed in their training in order to increase the dissemination of evidence-based treatment (i.e., ERP) and thus improve the treatment of OCD.

The outbreak of the COVID-19 pandemic has particularly affected people with obsessive-compulsive disorder (OCD). Exacerbation of obsessive-compulsive symptoms (OCS) has been suspected for those with contamination-related OCD (C-OCD). However, the course of OCS over the ongoing pandemic remains unclear. We assessed 268 participants with OCD (nâ¯=â¯184 with C-OCD) in an online survey at the beginning of the pandemic in Germany, reassessing 179 participants (66.8%, 104â¯C-OCD) three months later. We assessed severity of OCD (OCI-R), depression (PHQ-9), experiential avoidance, as well as functional and dysfunctional beliefs. Overall, OCS and depressive symptoms did not substantially change over time. However, when people with and without C-OCD were compared, symptoms improved in patients without C-OCD (nC-OCD) but remained stable in patients with C-OCD over time. Symptom improvement was associated with male gender, higher initial OCI-R, and nC-OCD. Experiential avoidance and beliefs at the beginning of the pandemic did not generally predict change in OCS. People with OCD, particularly those with nC-OCD, showed tentative signs for signs of adapting, whereas distress in those with C-OCD remained at a high level, underlining the burden for these patients. Clinicians should be informed about how to maintain effective treatment for C-OCD during a pandemic.

The COVID-19 pandemic has been associated with an increase in obsessive-compulsive disorder/symptoms (OCD/OCS). However, knowledge is limited regarding the trajectories of OCS during the pandemic, as well as their predictors and mechanisms (e.g., experiential avoidance, EA). The aim of this study was to describe the trajectories of OCS and the identification of associated factors. We assessed 1207 participants of the general population in March 2020 (t1) and June 2020 (t2). Pre-pandemic data was available from March 2014 for a subsample (n = 519). To define trajectories, we determined OCS status (OCS+/-). We performed a hierarchical multinomial logistic regression to investigate predictors of trajectories. Between t1 and t2, 66% of participants had an asymptomatic trajectory (OCS-/OCS-); 18% had a continuously symptomatic trajectory (OCS+/OCS+). Ten percent had a delayed-onset trajectory (OCS-/OCS+), and the recovery trajectory group (OCS+/OCS-) was the smallest group (6%). Higher education reduced the odds of an OCS+/OCS- trajectory. OCS in 2014 was associated with increased odds of showing an OCS+/OCS+ or OCS-/OCS+ trajectory. When EA at t1 and change in EA from t1 to t2 were added to the model, higher EA at t1 was associated with increased odds of scoring above the cut score on one or more of the assessments. A higher decrease in EA from t1 to t2 reduced the probability of showing an OCS+/OCS+ and an OCS-/OCS+ trajectory. While the current data supports a slight increase in OCS during the pandemic, trajectories differed, and EA seems to represent an important predictor for an unfavorable development.

Approximately 90% of problem and pathological gamblers remain untreated. This treatment gap may be diminished by the implementation of low-threshold treatment programs. As cognitive distortions play a crucial role in the development and maintenance of gambling problems, interventions targeting gambling-related biases may be particularly effective. The aim of the present study was to examine the feasibility, acceptance, and safety of a novel metacognitive training for individuals with gambling problems (Gambling-MCT). Twenty-five participants were included in an uncontrolled pilot trial with two assessment points (intervention). The intervention comprised eight training modules targeting gambling-specific cognitive distortions. At baseline and post assessment, symptom severity, as measured with the PG-YBOCS, and gambling-related cognitive distortions, as measured with the GABS, were assessed. In addition, interim assessments measuring session-specific changes were conducted. Subjective appraisal was examined after each module and also post treatment. On average, participants took part in 4.16 (SD = 2.84) training sessions. Both intent-to-treat and per protocol analyses showed significant improvements on the PG-YBOCS and the GABS (dz = 0.37-1.37). After Bonferroni correction for multiple testing, linear mixed models for the analysis of session-specific changes showed no deterioration in participants' mental state after any of the modules. Subjective appraisal of Gambling-MCT was good. The present pilot study provides first evidence for the feasibility, acceptance, and safety of Gambling-MCT. Recruitment of participants remains challenging, emphasizing the importance of overcoming patient-related treatment barriers. Future studies need to investigate the efficacy of Gambling-MCT in randomized controlled trials.

The COVID-19 pandemic has prompted global measures to prevent infection. Experts assume that it is particularly affecting people with obsessive-compulsive disorder (OCD), especially those with washing compulsions. Data, however, are currently lacking. 394 participants with OCD (nâ¯=â¯223 washers) participated in an online survey. Change in severity of OCD symptoms, reasons participants reported for the change (e.g., reduced mobility, reduced availability of cleaning products, economic factors, interpersonal conflicts), as well as participants' beliefs and experience associated with COVID-19 were assessed. 72 % of the participants reported an increase in OCD. This increase was significantly stronger in washers compared to non-washers. The worsening of symptoms was primarily associated with reduced mobility and interpersonal conflicts. Dysfunctional hygiene-related beliefs were significantly higher in washers than non-washers and were associated with greater symptom progression. Washers were more confident than non-washers about providing other people with helpful advice related to infection preventions. Washers, however, received more negative feedback from others in response to the advice they provided than non-washers. The majority of participants with OCD were negatively affected by the COVID-19 pandemic, and the negative effects were more pronounced in washers than in non-washers. Rapid interventions for OCD should be implemented to prevent long-term deterioration.
