Dropout rates in exposure with response prevention for obsessive-compulsive disorder: What do the data really say?

Exercise and health-related quality of life and work-related outcomes in primary care patients with anxiety disorders - A randomized controlled study

BACKGROUND

Exercise interventions show promise in the treatment of anxiety disorders, but effects on health-related quality of life (HR-QoL), work ability, and sick leave are little studied. We investigated these outcomes in a 12-week randomized controlled trial with a 1-year follow-up.

METHODS

Patients aged 18-65 (n = 222) with anxiety disorders from primary care centers in Gothenburg were randomized to a control group or one of two 12-week exercise intervention groups (low-intensity, [LI] and moderate/high-intensity, [HI]); 148 were evaluated at 12-weeks and 113 completed the 1-year follow-up. The EuroQol 5D (EQ5D; index and the visual analogue scale [VAS]), work ability score (WAS), presenteeism, and self-reported sick leave were assessed at baseline, 12 weeks, and 1 year. Improvements were defined by binary cut-offs for each scale. Binary logistic regression with odds ratios (OR) and 95 % confidence intervals (CI) were reported.

RESULTS

There were improved scores for EQ5D and WAS in the HI group compared to controls after 12 weeks (EQ5D index: 4.74 [1.91-11.7], EQ5D-VAS 4.00, [1.65-9.72], WAS 3.41 [1.24-7.37]) and 1 year (EQ5D index: 3.05 [1.05-8.81], EQ5D-VAS 3.20 [1.16-8.84], WAS 5.50 [1.85-16.3]). Post-hoc analysis showed higher ORs in participants on antidepressants (n = 75) (12-week EQ5D index: OR 9.95 [2.85-34.8]) and significant improvements in EQ5D scores for both intervention groups after 1 year. There were no between-group differences for presenteeism or sick leave.

LIMITATIONS

Discontinuation was high, mostly early after randomization (n = 74), as is common for anxiety interventions.

CONCLUSIONS

HI Exercise improves HR-QoL and work ability in anxiety patients, especially when combined with antidepressants.

Willingness to experience unpleasant thoughts, emotions, and bodily sensations at admission does not predict treatment outcome in inpatients with obsessive-compulsive disorder

BACKGROUND

Some persons with obsessive-compulsive disorder (OCD) refuse or drop out of treatment because of the aversive nature of exposure and response prevention therapy when they have to face and tolerate unpleasant thoughts, emotions, and bodily sensations. Indeed, one study suggested that a higher willingness to experience unpleasant thoughts, emotions, and bodily sensations (WTE) predicts a better treatment outcome, but this finding has not been replicated yet.

METHODS

We examined whether WTE at admission predicted treatment outcome in a sample of 324 inpatients with OCD who received a multimodal treatment that included cognitive-behavioral therapy with exposure and response prevention sessions.

RESULTS

Obsessive-compulsive symptoms (based on OCD-specific self-report questionnaires) decreased with medium-to-large effect sizes (all ps < 0.001) and global functioning (based on therapist ratings) increased with a large effect size (d = 1.3, p < 0.001) from admission to discharge. In contrast to previous findings, however, WTE did not predict treatment outcome (all ps > 0.005). The effect of WTE on treatment outcome remained non-significant when controlling for any comorbidity, age, sex, length of stay, and antidepressant medication and was not moderated by these variables.

CONCLUSIONS

Results indicate that higher WTE at the beginning of inpatient treatment does not facilitate improvements in obsessive-compulsive symptoms from admission to discharge. However, they also indicate that lower WTE at the beginning of inpatient treatment does not adversely affect treatment outcome, that is, even patients who indicate that they are unwilling to face the negative experiences associated with exposure and response prevention can still achieve considerable symptom reductions.

Metacognitive therapy versus exposure and response prevention for obsessive-compulsive disorder - A non-inferiority randomized controlled trial

OBJECTIVE

Exposure with response prevention (ERP) is the first-line treatment for obsessive-compulsive disorder (OCD). However, refusals, dropouts and the required high time and logistic effort constitute barriers to the use of ERP. In a non-inferiority randomized controlled trial, we compared metacognitive therapy (MCT) to exposure with response prevention (ERP) as treatments for OCD.

METHOD

74 outpatients received 12 weekly sessions of either manualized MCT or ERP, with primary outcomes assessed by blinded assessors using the Yale-Brown Obsessive Compulsive Scale (Y-BOCS) at pre-treatment, mid-treatment, post-treatment, and 6-month follow-up. Secondary outcomes included measures of depression and anxiety. Non-inferiority margin was specified at no less than d = 0.38 below the improvement reached by ERP, corresponding to a difference of about 3 points on the Y-BOCS.

RESULTS

Drop-out rates were low (<14%) and similar in both groups. Linear models indicated non-inferiority of MCT to ERP at post-treatment, but not at 6-month follow-up. While both groups showed comparable Y-BOCS improvements, the MCT group demonstrated a significantly greater reduction in state anxiety scores at post-treatment and follow-up.

CONCLUSIONS

Overall, MCT was not inferior to ERP, especially at post-treatment, suggesting it could be a treatment alternative. However, further research is needed to explore differential treatment indications.

Co-occurring PTSD in intensive OCD treatment: Impact on treatment trajectory vs. response

BACKGROUND

Obsessive-compulsive disorder (OCD) and co-occurring posttraumatic stress disorder (PTSD) is associated with more severe and chronic OCD. However, findings regarding treatment effectiveness of cognitive behavioral treatment (CBT) with exposure and response prevention (ERP) with this comorbidity are mixed. Research aimed at understanding the precise barriers to OCD treatment effectiveness for individuals with co-occurring PTSD may help elucidate unique treatment needs.

METHODS

The current study used linear regression and latent growth curve analysis comparing treatment response and trajectory from patients with OCD (n = 3083, 94.2 %) and OCD + PTSD (n = 191, 5.2 %) who received CBT with ERP in two major intensive OCD treatment programs.

RESULTS

Although patients with OCD + PTSD evidenced similar trajectories of overall severity change, patients at one site required nearly 11 additional treatment days to achieve comparable reduction in OCD severity. Further, at the dimensional level, those with OCD + PTSD had poorer treatment response for unacceptable thoughts and symmetry symptoms. The moderate effect for unacceptable thoughts, indicating the widest gap in treatment response, suggests these symptoms may be particularly relevant to PTSD.

LIMITATIONS

Findings are limited by a naturalistic treatment sample with variation in treatment provision.

CONCLUSIONS

Findings emphasize caution in using a one-size-fits-all approach for patients with co-occurring OCD + PTSD within intensive OCD treatment programs, as broadly defined outcomes (e.g., reduction in overall severity) may not translate to reduction in the nuanced symptom dimensions likely to intersect with trauma. Unacceptable thoughts and symmetry symptoms, when co-occurring with PTSD, may require a trauma-focused treatment approach within intensive OCD treatment.

Exposure therapy tailored to inhibitory learning principles in a naturalistic setting: an open pilot trial in obsessive-compulsive outpatient care

Inhibitory learning (IL) theory offers promising therapeutic strategies. However, more evidence is needed, especially regarding OCD treatment in routine care. The present pilot study investigated the positive and negative effects of IL-focused cognitive-behavioral therapy (CBT) in a university outpatient setting. A total of N = 21 patients (57.14% male, mean age 31.14, SD = 12.39 years) passed through manualized therapy delivered by licensed psychotherapists. Between the first and 20th IL-focused CBT session, obsessive-compulsive symptoms (Obsessive Compulsive Inventory-Revised, d = 3.71), obsessive beliefs (Obsessive-Beliefs Questionnaire, d = 1.17), depressive symptoms (Beck Depression Inventory, d = 3.49), and overall psychological distress (Global Severity Index, d = 3.40) decreased significantly (all ps < 0.01). However, individual patients reported some negative effects of therapy. The results underline the value of thorough investigations of novel therapeutic interventions in naturalistic settings.

Feeling uncertain despite knowing the risk: Patients with OCD (but not controls) experience known and unknown probabilistic decisions as similarly distressing and uncertain

Patients with obsessive compulsive disorder (OCD) present as risk-averse and avoidant of feared stimuli, yet the literature examining risk aversion in OCD is conflicting. One possible explanation is that patients may exhibit aversion only on ambiguous tasks where the likelihood of possible outcomes is unknown. To test this idea, the current study assigned 30 patients with OCD versus 30 non-psychiatric controls (NPC) to conditions of known versus unknown risk (i.e., probabilities) on the Beads Task. Importantly, the task involved real financial stakes. We also examined self-reported intolerance of uncertainty (IU) as a mechanism. Results revealed a significant risk information x group interaction for certainty about the decision. Specifically, while NPCs felt significantly less certain on the unknown risk (versus known risk) task, the OCD group felt uncertain regardless of risk information. Results also revealed a significant main effect of group for distress after deciding, such that the OCD group was more distressed across all task versions compared to NPCs. Elevated trait IU was associated with higher task-related distress. Results indicate that even when patients with OCD are given information about likelihoods, they still feel uncertain and experience distress. Findings have clinical implications for addressing risk aversion and ambiguity/uncertainty in treatment.

Mixed results for exposure and response prevention therapy in mixed reality for patients with contamination-related obsessive-compulsive disorder: A randomized controlled pilot study

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.

Unwanted outcomes in cognitive behavior therapy for pathological health anxiety: a systematic review and a secondary original study of two randomized controlled trials

INTRODUCTION

Cognitive behavior therapy (CBT) is effective for pathological health anxiety, but little is known about unwanted outcomes.

AREAS COVERED

We investigated unwanted outcomes in the form of adverse events, overall symptom deterioration, and dropouts in CBT for pathological health anxiety based on a systematic review of 19 randomized controlled trials (PubMed, PsycInfo, and OATD; last updated 2 June 2023; pooled N = 2188), and then a secondary original study of two randomized controlled trials (pooled N = 336). In the systematic review, 10% of participants in CBT reported at least one adverse event and 17% dropped out. Heterogeneity was substantial. In the original investigation, 17% reported at least one adverse event, 0-10% met criteria for overall symptom deterioration, and 10-19% dropped out. In guided Internet-delivered CBT, dropouts were more common with lower education and lower credibility/expectancy ratings. Higher adherence was associated with a larger reduction in health anxiety.

EXPERT OPINION

Unwanted effects are routinely seen in CBT for pathological health anxiety, but, under typical circumstances, appear to be acceptable in light of the treatment's efficacy. There is a need for more consistent methods to improve our understanding adverse events, dropouts, and overall symptom deterioration, and how these outcomes can be prevented.

Efficacy of exposure and response prevention therapy in mixed reality for patients with obsessive-compulsive disorder: study protocol for a randomized controlled trial

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.

Things that make you go Hmm: Myths and misconceptions within cognitive-behavioral treatment of obsessive-compulsive disorder

The past four decades have yielded a robust body of evidence supporting the efficacy and effectiveness of cognitive-behavioral therapy (CBT) as a gold-standard treatment for obsessive-compulsive disorder (OCD) across the lifespan. Exposure and response prevention (E/RP) has been identified as a key component of this approach. Despite robust research support for CBT with E/RP, several myths and misconceptions continue to proliferate in both research and practice settings. Such myths and misconceptions are concerning, as they lack empirical basis, may hinder widespread dissemination and implementation of CBT for OCD, and run contrary to the practice of evidence-based psychological medicine. Focusing on the importance of promoting evidence-based practice and generative clinical science, the present review article synthesizes relevant research within the field of treatments for OCD to address the following myths / misconceptions: (a) uncertainty exists concerning the evidence base supporting CBT for OCD, (b) E/RP attrition and dropout rates are unacceptably high due to excessive risk and perceived patient intolerability, and (c) alternative treatments for OCD need to be expeditiously developed due to major limitations of E/RP. Recommendations for future research and clinical dissemination and implementation to further advance a generative clinical science of OCD treatment are discussed.

Perfectionism as Possible Predictor for Treatment Success in Mindfulness-Based Cognitive Therapy and Metacognitive Training as Third-Wave Treatments for Obsessive-Compulsive Disorder

Background

Identifying predictors of treatment outcome can guide treatment selection and optimize use of resources. In patients affected by obsessive-compulsive disorder (OCD), perfectionism has emerged as one possible predictor, with some data suggesting that cognitive-behavioral therapy outcomes are poorer for more perfectionistic patients. Findings so far are inconsistent, however, and research has yet to be extended to newer treatment approaches.

Methods

We administered measures of concern over mistakes, clinical perfectionism, as well as OCD and depression symptom severity to a sample of OCD patients in out-patient group treatments (N = 61), namely, metacognitive training (MCT-OCD) or mindfulness-based cognitive therapy (MBCT) for OCD. Hierarchical data over time was submitted to multi-level analysis.

Results

Neither concern over mistakes nor clinical perfectionism at baseline predicted OCD symptoms across time points. However, concern over mistakes at baseline did significantly predict comorbid depressive symptoms. Furthermore, exploratory analysis revealed change in clinical perfectionism during treatment as a predictor of OCD symptoms at follow-up.

Conclusion

These results suggest that initial concern over mistakes may not prevent patients with OCD from benefitting from third-wave treatments. Change in clinical perfectionism may present a putative process of therapeutic change. Limitations and avenues for future research are discussed.

The association between OCD and Shame: A systematic review and meta-analysis

BACKGROUND

Due to rumination and self-criticism over unwanted obsessions and repetitive rituals, shame is a common emotion experienced by individuals with obsessive-compulsive disorder (OCD). Shame is also theorized to have relevance to unacceptable thoughts in OCD. However, empirical research looking at the relationship between OCD and shame is still emerging and findings have been mixed.

OBJECTIVES

Our review systematically examines the association of shame with OCD and unacceptable thoughts.

METHODS

The last updated search was conducted across five databases between 27 and 29 February 2022. The final selection included 20 papers, 18 of which were used in the primary meta-analysis to calculate pooled effect sizes between OCD and shame measures using a random effects model. In a separate analysis, three papers were used to calculate pooled effect sizes between shame and OCD symptom dimensions also using a random effects model.

RESULTS

The meta-analyses identified a significant, moderate and positive correlation between total OCD and shame scores r = .352, 95% CI [0.260, 0.438]. In addition, significant, weak and positive relationships were found between shame and three OCD symptom dimensions: unacceptable thoughts r = .252, 95% CI [-0.467, 0.9708], harm obsessions r = .224, CI [-0.190, 0.638] and symmetry concerns r = .200, CI [-0.108, 0.509].

LIMITATIONS

Shame measures in the reviewed studies were not specific to OCD, and between-study variance in the analyses examining unacceptable thoughts was significant.

CONCLUSIONS

Our findings support a medium positive relationship between shame and OCD. As shame in OCD can be a barrier to seeking treatment and impair quality of life, it is imperative to address this emotion through psychoeducation, assessment and treatment.

Anxiety sensitivity as a predictor, and non-specific therapeutic factors as predictors and mediators of CBT outcome for obsessive-compulsive disorder in a naturalistic mental health setting

OBJECTIVE

We examined the unique predictive strength of anxiety sensitivity (AS) and the role of expectancy, credibility, and therapeutic alliance (TA) as predictors and mediators of cognitive-behavioral treatment (CBT) outcomes in obsessive-compulsive disorder (OCD).

METHOD

The current study is a prospective cohort study. Participants (N = 116) were treatment-seeking individuals with a primary diagnosis of OCD. Independent raters assessed patients on Yale-Brown Obsessive-Compulsive Scale (YBOCS) and Anxiety Sensitivity Index-3 at baseline, post-intervention, and three-month follow-up. Participants responded to the Credibility and Expectancy questionnaire and Working Alliance Inventory-Short revised at baseline, first-session, and mid-session.

RESULTS

The individual addition of AS, end-of-first-session credibility and expectancy, mid-session credibility and expectancy, and therapeutic alliance predicted significant CBT outcomes. There was a moderate positive correlation between baseline OCD severity and the global score of AS, but a weak one with AS dimensions. Both expectancy and credibility significantly improved from baseline to end-of-first-session treatment. End-of-first and third-session outcome expectancies, not credibility, have significant, indirect effects on OCD CBT outcomes.

CONCLUSIONS

AS, within-session credibility and expectancies and TA independently predict CBT outcomes. Within-sessions outcome expectancies mediate CBT outcomes in OCD, not credibility. Expectancy and credibility both include state-like elements that can be influenced to enhance the outcomes of CBT. Proposals for reducing treatment barriers in CBT for OCD are offered.

Cognitive-Behavioral Therapy for Obsessive-Compulsive Disorder

Obsessive-compulsive disorder (OCD) is characterized by the presence of debilitating obsessions and compulsions. Cognitive and behavioral models of OCD provide a strong theoretic and empirical foundation for informing effective psychotherapeutic treatment. Cognitive-behavioral therapy (CBT) for OCD, which includes a deliberate emphasis on exposure and response/ritual prevention, has consistently demonstrated robust efficacy for the treatment of pediatric and adult OCD and is the front-line psychotherapeutic treatment for OCD. Two case vignettes describing CBT for OCD in practice as well as recommendations for clinicians are provided.

Psychotherapies and digital interventions for OCD in adults: What do we know, what do we need still to explore?

BACKGROUND

Despite significant advances in the understanding and treatment of obsessive compulsive disorder (OCD), current treatment options are limited in terms of efficacy for symptom remission. Thus, assessing the potential role of iterative or alternate psychotherapies is important. Also, the potential role of digital technologies to enhance the accessibility of these therapies, should not be underestimated. We also need to embrace the idea of a more personalized treatment choice, being cognisant of clinical, genetic and neuroimaging predictors of treatment response.

PROCEDURES

Non-systematic review of current literature on emerging psychological and digital therapies for OCD, as well as of potential biomarkers of treatment response.

FINDINGS

A number of 'third wave' therapies (e.g., Acceptance and Commitment Therapy, Mindfulness-Based Cognitive Therapy) have an emerging and encouraging evidence base in OCD. Other approaches entail employment of elements of other psychotherapies such as Dialectical Behaviour Therapy; or trauma-focussed therapies such as Eye Movement Desensitisation and Reprocessing, and Imagery Rescripting and Narrative Therapy. Further strategies include Danger Ideation Reduction Therapy and Habit Reversal. For these latter approaches, large-scale randomised controlled trials are largely lacking, and the precise role of these therapies in treating people with OCD, remains to be clarified. A concentrated 4-day program (the Bergen program) has shown promising short- and long-term results. Exercise, music, and art therapy have not been adequately tested in people with OCD, but may have an adjunctive role. Digital technologies are being actively investigated for enhancing reach and efficacy of psychological therapies for OCD. Biomarkers, including genetic and neuroimaging, are starting to point to a future with more 'personalised medicine informed' treatment strategizing for OCD.

CONCLUSIONS

There are a number of potential psychological options for the treatment of people with OCD who do not respond adequately to exposure/response prevention or cognitive behaviour therapy. Adjunctive exercise, music, and art therapy might be useful, albeit the evidence base for these is very small. Consideration should be given to different ways of delivering such interventions, including group-based, concentrated, inpatient, or with outreach, where appropriate. Digital technologies are an emerging field with a number of potential applications for aiding the treatment of OCD. Biomarkers for treatment response determination have much potential capacity and deserve further empirical testing.

Exposure Therapy and Its Mechanisms

Exposure therapy is the gold-standard treatment approach for pathological anxiety. This therapeutic approach builds on principles of extinction training from traditional fear conditioning and extinction protocols. In this chapter, we discuss principles of exposure therapy in the clinic and the laboratory experimental results that guide our decisions in the therapy. We discuss emotional processing theory and inhibitory learning principles, with a focus on expectation violation. We conclude with future research directions needed to improve exposure therapy outcomes among patients with anxiety-related disorders.

I Think I Can: The Role of Self-Efficacy in Exposure to Contamination

Introduction: Self-efficacy (SE) has been explored extensively within the field of psychology. Despite a rich literature demonstrating its positive effect on various behavioral outcomes, including psychological treatment outcomes, little is known about the impact of SE on outcomes related to obsessive-compulsive disorder. To fill this critical gap in the literature, this study aims to examine the relationship between SE beliefs and contamination-related approach behavior and to determine whether increasing SE may improve engagement in exposure-based interventions for contamination fears. Method: Participants (N = 120) were randomly assigned to complete a contamination-related behavioral approach task (CR-BAT) immediately following either a SE-boosting exercise or a non-SE related control. Results: Self-reported contamination-relevant SE was positively correlated with approach behavior during the CR-BAT. However, there were no differences between conditions in contamination-related SE or approach behavior during the CR-BAT. Nevertheless, participants in the SE-boosting condition reported lower levels of anxiety during the CR-BAT than did those in the control condition, suggesting that the manipulation was effective in reducing subjective distress. Discussion: Future research using more effective methods to manipulate SE is required to examine the causality of this relationship.

The therapeutic alliance in cognitive-behavioral therapy for obsessive-compulsive disorder: A systematic review and meta-analysis

Background

The therapeutic alliance has been recognized as one of the most researched key elements of treatment across different therapeutic approaches and diagnostic domains. Despite its importance, our current understanding of its clinical relevance in patients with obsessive-compulsive disorder (OCD) is still debated. This study aimed to examine empirical evidence on the effect of alliance on treatment outcomes in Cognitive Behavioral Therapy (CBT) in patients with OCD in a systematic review and meta-analysis.

Methods

Original peer-reviewed articles until March 2022 were included if they were (1) written in English; (2) included a clinical group with a current primary OCD diagnosis; (3) involved individual CBT; (4) used a validated therapeutic alliance scale that was related to the outcome measurement; (5) reported an effect size.

Results

Thirteen studies were included, six of which contained sufficient statistical information to be included in the meta-analysis. A total of 897 patients took part in all reviewed studies. We found a modest effect of alliance on post-treatment outcome [Tau 2 = -0.1562 (C.I. 95%: -0.2542 to -0.0582)].

Discussion

The results show the existence of considerable variability and methodological inconsistencies across studies. We discuss the role of methodological factors that could account for this divergence, the research limitations, and the implications for current research.

Exposure and Response Prevention in Virtual Reality for Patients with Contamination-Related Obsessive-Compulsive Disorder: a Case Series

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.

Cognitive Training via a Mobile Application to Reduce Obsessive-Compulsive-Related Distress and Cognitions During the COVID-19 Outbreaks: A Randomized Controlled Trial Using a Subclinical Cohort

Obsessive-compulsive disorder (OCD) is a persistent psychiatric disorder causing significant impairment in functioning. The COVID-19 pandemic has exacerbated OCD-related symptoms and interrupted access to treatment. Recent research suggests mHealth apps are promising tools for coping with OCD symptoms. This randomized controlled trial evaluated the effects of a CBT-based mobile application designed to reduce OCD symptoms and cognitions in community participants considered at high risk of developing OCD symptoms. Following initial screening (n = 924), fifty-five community participants scoring 2 standard deviations above the OCI-R mean were randomized into two groups. In the immediate-app use group (iApp; n = 25), participants started using the application at baseline (T0), 4 min a day, for 12 days (T0-T1). Participants in the delayed-app group (dApp; n = 20) started using the mobile application at T1 (crossover) and used the app for the following 12 consecutive days (T1-T2). Intention to treat analyses indicated that using the app for 12 consecutive days was associated with large effect-size reductions (Cohen's d ranging from .87 to 2.73) in OCD symptoms and maladaptive cognitions in the iApp group (from T0 to T1) and dApp group (from T1 to T2). These reductions were maintained at follow-up. Our findings underscore the usefulness of brief, low-intensity, portable interventions in reducing OCD symptoms and cognitions during the pandemic.

Group Metacognitive Therapy for Obsessive-Compulsive Disorder in a Routine Clinical Setting: An Open Trial

Obsessive-compulsive disorder (OCD) is often a chronic disorder characterised by uncontrollable, reoccurring thoughts (obsessions), and/or behaviours (compulsions). Accumulating evidence suggests that metacognitive beliefs may underlie many of the processes implicated in the formation and perpetuation of OCD. Metacognitive therapy (MCT) for OCD aims to modify these maladaptive metacognitive beliefs and processes to treat this debilitating disorder. The current study examines the outcome of a pilot trial of MCT for OCD in 26 (17 females; 9 males) adults (18–64 years) referred to a specialist outpatient service. Results were promising, with significant decreases in OCD and depression symptoms, which were maintained at the 3-month follow-up. The improvement in Yale-Brown Obsessive-Compulsive Scale scores between pre-treatment and follow-up in the completer sample (n=22) was large (d=1.29), and comparable to outcomes of well-established treatments. These encouraging results add to early empirical support for the effectiveness of group MCT as an OCD treatment alternative, as well as reinforcing the role of metacognitions contributing to this disorder.

It's all in the name: why exposure therapy could benefit from a new one

Exposure therapy for anxiety and related disorders is the psychological intervention with the strongest support for its efficacy and effectiveness to date. Yet, it is the least used evidence-based intervention in routine clinical practice, with a long-acknowledged public relations problem. Despite a wealth of research aimed at improving uptake of exposure, exposure's marketing and branding remains an untapped target. We first introduce principles from the marketing literature to propose that the field take steps toward a rebranding and repackaging of exposure therapy to support efforts to implement it widely. Second, we present preliminary data on clinician preferences for the use of alternative terminology developed to be more palatable and marketable - "Supported Approach of Feared Experiences - Cognitive Behavioral Therapy (SAFE-CBT)" - compared to traditional terminology. This initial survey indicated that most clinicians preferred use of the SAFE-CBT term when talking to patients, whereas only a minority preferred it for use among training clinicians. We conclude by discussing implications of these results for future efforts to implement exposure therapy more widely and set an agenda for future research in this space.

Maximizing the non-specific factors in brief cognitive behavioral therapy for panic disorder and agoraphobia: A multiple baseline case series documenting feasibility and initial efficacy

There is evidence for non-specific factors impacting treatment outcomes, with pragmatic concerns regarding the need to popularize briefer formats of cognitive behavioral therapy (CBT). The need to have more culturally suitable and acceptable forms of CBT is also indicated. We evaluated the feasibility and efficacy of a brief 5 session CBT (bCBT) in participants (N = 4) with panic disorder (PD) and agoraphobia, using a non-concurrent multiple baseline design. In this case series, efforts were made to maximize non-specific factors of psychotherapy in bringing about treatment outcomes. Reliable and significant treatment effects were observed at post-intervention and follow-up assessments. The present study offers preliminary evidence of a bCBT protocol that comprises the efforts to maximize the non-specific factors in psychotherapy such as credibility, expectancy, and the therapeutic alliance in bringing treatment outcomes; however, further controlled evaluation is warranted. We also discuss the mechanisms contributing to these treatment outcomes in the present protocol.

Anti-Disgust Cognitive Behavioral Therapy for Contamination-Based Obsessive Compulsive Disorder: A Randomized Controlled Clinical Trial

Background: Disgust is a strong and persistent emotion that frequently occurs during exposure-based treatments for contamination-based obsessive compulsive disorder (C-OCD). This study aimed to examine the efficacy of augmenting cognitive behavioral therapy (CBT) with a novel type of anti-disgust cognitive intervention in reducing the severity of OCD, disgust propensity/sensitivity, and refusal rate of exposure and response prevention, while simultaneously increasing acceptance of disgust. Materials and Methods: Fifty-five individuals with C-OCD (mean age 28.1 years, SD = 3.52; 77% female) were randomly assigned to 15 weekly sessions of anti-disgust plus CBT (AD-CBT) or CBT alone. They were evaluated for outcomes four times (pretreatment, prior to exposure and response prevention (ERP) sessions, posttreatment, and three-month follow-up), and mixed-design ANOVAs were used to analyze the data. Results: The findings indicated that when compared to CBT alone, AD-CBT significantly reduced OCD severity, disgust propensity/sensitivity, and concurrently increased disgust acceptance (p < 0.001). Additionally, engaging in an anti-disgust cognitive intervention was associated with lower ERP refusal rate (4% vs. 16%). The superiority of AD-CBT over CBT persisted through the three-month follow-up period. Conclusions: The current study suggests that supplementing CBT for C-OCD with an anti-disgust cognitive intervention significantly increased acceptance of disgust and decreased the refusal rate of ERP, OCD severity, and disgust-related factors.

Cognitive-Behavioral Treatment of Obsessive-Compulsive Disorder: The Results of a Naturalistic Outcomes Study

Cognitive−behavioral therapy is a well-established treatment for obsessive−compulsive disorder (OCD). There are a variety of cognitive and behavioral strategies, and it is necessary to analyze the outcomes of the treatments. The aim of the present study is to verify the effectiveness of a treatment that combines evidence-based procedures and specific cognitive interventions highlighting the issue of acceptance. Forty patients with OCD were recruited and underwent a specific treatment procedure. All patients had a psychodiagnostic assessment for OCD using the Y−BOCS (Yale−Brown obsessive−compulsive scale) performed twice: before treatment (t0) and after nine months (t1). Data analysis showed a decrease in the scores between t0 and t1 according to the Y−BOCS in terms of the interference, severity, and impairment of obsessive−compulsive symptoms. A repeated-measures ANOVA showed a significant reduction in symptoms after treatment, with values of F (1, 39) = 137.56, p < 0.001, and η2 = 0.78. The ANOVA results were corroborated by a Wilcoxon signed-rank test. A reliable change index analysis indicated that 33 participants reported improvements in symptoms, of which 23 were clinically significant. The results showed clinical relevance for OCD treatment and highlighted how this cognitive procedure favored positive outcomes.

Optimizing first line treatments for adults with OCD

OCD is characterized by obsessions (recurrent, intrusive, unwanted thoughts, images or impulses and compulsions (repetitive behaviors or mental acts that the individual feels compelled to perform), which can manifest together or separately (Fineberg et al., 2020). NICE guidelines suggest that low intensity psychological treatments (including ERP) is the first line treatment for OCD, and that a "stepped care" treatment approach for OCD reserves combination treatment for adults with OCD with severe functional impairment, and for adults without an adequate response to: 1) treatment with an SSRI alone (12 weeks duration) or 2) CBT (including ERP) alone (NICE, 2005). Existing US treatment guidelines (APA guidelines) suggest that there are three first-line treatments for OCD (SSRI, CBT, SSRI+CBT) and recommends combined treatment for patients with an unsatisfactory response to monotherapy or for patients with severe OCD. Although, systematic review and meta-analysis of studies published in 1993-2014 suggest that combination treatment was not significantly better than CBT plus placebo (Ost et al., 2015), based on data from a recent systematic and meta-analysis which searched the two controlled trials registers maintained by the Cochrane Collaboration Common Mental Disorders group, the combination treatment approach is likely to be more effective than psychotherapeutic interventions alone, at least in severe obsessive-compulsive disorder (Skapinakis et al., 2016a). Based on data from Optimal treatment for OCD study conducted by Fineberg et al., (2018) combined treatment appeared to be the most effective especially when compared to CBT monotherapy, but SSRI monotherapy was found as the most cost effective. In this review we summarize available treatment recommendations.

Therapists’ Emotional Reactions to Patients with Obsessive–Compulsive Disorder: The Role of Therapists’ Orientation and Perfectionism

Therapist’s emotional response towards patients with obsessive–compulsive disorder (OCD) is under-investigated. This aspect might provide valuable information about therapists’ difficulties during sessions and support supervisory practice, since a proportion of OCD patients drop out due to issues related to the therapeutic relationship. In a sample of therapists, we explored the effects of therapists’ orientation (cognitive behavioural versus psychodynamic) and perfectionistic traits on their emotional responses towards patients with OCD, controlling for other variables potentially related to emotional response towards patients (i.e., therapists’ gender/age and patient’s comorbid personality disorders). Ninety-four therapists (74 women and 20 men; mean age = 42.07 ± 10.17 years), of which 47 (50%) had a cognitive behavioural therapy (CBT) and 47 (50%) a psychodynamic orientation matched on gender and age, completed the Therapist Response Questionnaire and Frost Multidimensional Perfectionism Scale. Therapists with a CBT orientation reported less negative emotional responses, i.e., lower overwhelmed/disorganized, hostile/angry, criticised/devalued, parental/protective and special/over-involved emotions towards patients than therapists with a psychodynamic orientation. Therapists with higher perfectionistic traits (i.e., parents’ expectations/evaluation) had higher hostile/angry reactions, those with higher concerns over mistakes and doubts about actions had more intense criticised/devalued emotions, while those with stronger concerns with precision, order and organization had lower disengagement responses. The present study is the first investigation which sheds some light on the emotional responses of therapists towards OCD patients. Therapists’ CBT orientation and lower perfectionistic traits might be associated with better emotions. Therapists’ emotional responses, their psychotherapeutic orientation and levels of perfectionism should be considered during supervisory practice.

Obsessive-Compulsive Disorders

PURPOSE OF REVIEW

This article describes the phenomenology and clinical presentation of obsessive-compulsive disorder (OCD), a common but underdiagnosed psychiatric disorder. Guidance for effectively identifying obsessive-compulsive symptoms is provided, and treatment options, including psychotherapy, pharmacologic management, and neuromodulation approaches for treatment-resistant OCD, are discussed.

RECENT FINDINGS

OCD affects 2% to 3% of adults worldwide and is associated with substantial individual disability and societal costs. Lack of recognition of common OCD symptom types, in addition to shame and fear of stigma on the part of patients, has created an average delay in diagnosis by almost 10 years and a delay in effective treatment (ie, a treatment gap) of nearly 2 years. Cognitive-behavioral therapy (CBT), specifically a form of CBT that includes a type of behavioral intervention called exposure and response prevention, remains the most effective form of treatment for OCD. If CBT is not effective or not available, pharmacologic treatment with selective serotonin reuptake inhibitors (SSRIs) or clomipramine, a nonselective serotonin reuptake inhibitor, can also be of benefit. Neuromodulation approaches such as deep brain stimulation and transcranial magnetic stimulation are rapidly emerging as effective treatments for OCD, particularly for patients who have not experienced an adequate response to psychotherapy or pharmacologic management.

SUMMARY

OCD affects more than one in every 50 adults in the United States but is recognized and adequately treated in fewer than half of those affected. Early intervention and appropriate treatment can substantially reduce OCD symptom severity, improve quality of life, and minimize the functional disability associated with this chronic and often debilitating illness.

Behavioral Therapy Teams for Obsessive-Compulsive Disorder: Lessons Learned From a Pilot Randomized Trial in a Community Mental Health Center

Community mental health centers (CMHCs) provide the majority of mental health services for low-income individuals in the United States. Exposure and response prevention (ERP), the psychotherapy of choice for obsessive-compulsive disorder (OCD), is rarely delivered in CMHCs. This study aimed to establish the acceptability and feasibility of testing a behavioral therapy team (BTT) intervention to deliver ERP in CMHCs. BTT consisted of individual information-gathering sessions followed by 12 weeks of group ERP and concurrent home-based coaching sessions. The sample consisted of 47 low-income individuals with OCD who were randomized to receive BTT or treatment as usual (TAU). Symptom severity and quality-of-life measures were assessed at pretreatment, posttreatment, and 3- and 6-month posttreatment. Feasibility of training CMHC staff was partially successful. CMHC therapists successfully completed rigorous training and delivered ERP with high fidelity. However, training paraprofessionals as ERP coaches was more challenging. ERP was feasible and acceptable to patients. BTT participants were more likely than TAU participants to attend their first therapy session and attended significantly more treatment sessions. A large between-group effect size was observed for reduction in OCD symptoms at posttreatment but differences were not maintained across 3- and 6-month follow-ups. For BTT participants, within-group effect sizes reflecting change from baseline to posttreatment were large. For TAU participants, depression scores did not change during the active treatment phase but gradually improved during follow-up. Results support feasibility and acceptability of ERP for this patient population. Findings also underscore the importance of implementation frameworks to help understand factors that impact training professionals.

Inside OCD: Perspectives on the Value of Storytelling with Individuals with OCD and Family Members

The Center for Arts in Medicine at the University of Florida (UF) partnered with the UF Center for OCD, Anxiety, and Related Disorders to develop a storytelling program for individuals with obsessive compulsive disorder (OCD) and their families. Over ten weeks, participants shared stories regarding their experiences with OCD and engaged in theater and storytelling exercises. In collaboration with each other and the facilitators, participants workshopped and transformed their stories into a cohesive theatrical performance. Participants performed in front of a live audience and engaged in a post-show discussion with the audience, which focused on the diagnosis of OCD, stigma regarding the illness, and the benefits of the program. Program members participated in a post-program focus group and completed a qualitative and quantitative online survey. Participants reported improved understanding of their OCD, more acceptance from family and friends, less shame and guilt related to their OCD, and more confidence about sharing their OCD stories. Although the program was not designed to be therapeutic, participants also reported therapeutic value. Preliminary findings of this study suggest storytelling programs can lead to a reduction in both self-stigma and community stigma; improvement of understanding of the lived experience of OCD by families, loved ones, and clinicians; and facilitation of interpersonal connections.

Mindfulness-based and acceptance-based programmes in the treatment of obsessive-compulsive disorder: a study protocol for a systematic review and meta-analysis

INTRODUCTION

Cognitive-behavioural therapy (CBT) with exposure and response prevention is the recommended standard for the treatment of obsessive-compulsive disorder (OCD). However, a high proportion of patients refuse this treatment, do not respond or relapse shortly after treatment. Growing evidence suggests that mindfulness-based and acceptance-based programmes (MABPs) are an effective option for the treatment of OCD. This systematic review and meta-analysis will examine the effectiveness of MABPs in treating OCD. We also aimed to explore potential moderators of the programmes' effectiveness.

METHODS AND ANALYSIS

We will systematically search MEDLINE, Embase, PsycINFO, PSYINDEX, Web of Science, CINAHL and Cochrane Register of Controlled Trials (no language restrictions) for studies that evaluate the effect of MABPs on patients with OCD. We will conduct backward and forward citation searches of included studies and relevant reviews and contact corresponding authors. The primary outcome will be pre-post intervention change in symptom severity. A secondary outcome will be change in depressive symptoms. Two reviewers will independently screen the records, extract the data and rate the methodological quality of the studies. We will include both controlled and uncontrolled trials. Randomised controlled trials will be meta-analysed, separately assessing between-group effects. A second meta-analysis will assess the within-group effect of all eligible studies. We will explore moderators and sources of heterogeneity such as the specific programme, study design, changes in depressive symptoms, hours of guided treatment, control condition and prior therapy (eg, CBT) using metaregression and subgroup analyses. We will perform sensitivity analyses using follow-up data. A narrative synthesis will also be pursued. We will use the Grading of Recommendations Assessment, Development and Evaluation (GRADE) system to assess the quality of the evidence.

Association between obsessive-compulsive and related disorders and experiential avoidance: A systematic review and meta-analysis

The associations between the distinct types of obsessive-compulsive and related disorders and experiential avoidance have received mixed evidence. We, thus, undertook this meta-analysis to i) re-examine the association between obsessive-compulsive disorder and experiential avoidance, ii) extend this association to hoarding disorder, trichotillomania, and body dysmorphic disorder, and iii) identify potential variables affecting these associations. Five databases, including Medline, Embase, PsychINFO, Web of Science and CINAHL, were searched until March 15th, 2021. Meta-analyses based on random-effect models were performed. Heterogeneity and publication bias tests were applied using the I² statistic and the Egger's test. Meta-regression analyses were performed to identify potential moderators affecting the strength of these associations. Thirty-six unique studies based on n = 11,859 participants were identified. The association between obsessive-compulsive disorder and experiential avoidance was moderate (SMD = 0.75, 95% CI = 0.57-0.92), whereas the associations between individual obsessive-compulsive symptoms, including obsessions, responsibility for harm, ordering, checking, washing and neutralizing, and experiential avoidance ranged from low to strong (SMD ranged between 0.41 and 1.06, 95% CI = 0.25 to 1.40). The associations between hoarding disorder (SMD = 0.93, 95% CI = 0.46-1.40), trichotillomania (SMD = 0.56, 95% CI = 0.48-0.63), body dysmorphic disorder (SMD = 1.55, 95% CI = 0.72-2.37) and experiential avoidance were moderate to strong. Meta-regression analyses demonstrated that studies using the AAQ/AAQ-II scales for measuring experiential avoidance, and/or self-report scales for assessing OCRDs contributed smaller effect sizes. These findings suggest that reducing experiential avoidance may be a viable way of complementing exposure strategies in alleviating obsessive-compulsive and related symptoms.

A Review of Motivational Interviewing in Cognitive Behavioral Therapy for Obsessive-Compulsive Disorder

Although cognitive behavioral therapy (CBT) is a highly effective treatment for individuals with obsessive-compulsive disorder (OCD), a portion people with OCD do not benefit fully from CBT due to ambivalence about participating in treatment, nonadherence to exposure exercises, and dropout. This paper reviews the promising evidence for motivational interviewing (MI) as a therapeutic approach that is well suited to address these issues and potentially improve treatment outcomes. It will also provide a discussion of MI processes that may enhance CBT for OCD which can foster a collaborative relationship that integrates a patient's own goals and values into exposure planning, helps resolve ambivalence or reluctance to engage in exposure exercises and builds and supports patients' intrinsic motivation to participate in treatment. The review will conclude with a case report describing the use of pre-CBT MI for an individual with OCD.

Exposure therapy in a virtual environment: Validation in obsessive compulsive disorder

Exposure and response prevention (ERP) is the current first-line psychological treatment for Obsessive-compulsive disorder (OCD). However, substantial inter-individual variability exists in treatment outcomes, including inadequate symptom improvements, and notable refusal and attrition rates. These are driven, in part, by impracticalities in simulating intrusive thoughts within clinical settings. Virtual reality (VR) offers the potential of overcoming these limitations in a manner that allows for finely controlled anxiety-provoking scenarios to be created within supportive clinical settings. To validate the potential of VR for treating contamination-based OCD, 22 patients undertook a VR ERP session and a matched session of the current gold-standard of in vivo ERP. In VR, patients were immersed within a contamination environment that permitted flexible delivery of customisable, graded exposure tasks. The VR environment utilised HTC Vive hardware, to allow for patients to both interact with, and physically move through the environment. Subjective and objective measures of distress were recorded, including heart and respiration rates. These measures indicate virtual and in vivo ERP sessions provoke consistent anxiety profiles across an exposure hierarchy. Virtual exposure was advantageous for engagement and adherence to tasks, and the therapeutic alliance was upheld. VR is a promising mechanism for ERP in contamination OCD.

Integrating Exposure and Response Prevention With a Mobile App to Treat Obsessive-Compulsive Disorder: Feasibility, Acceptability, and Preliminary Effects

Many individuals with obsessive-compulsive disorder (OCD) do not receive evidence-based care (specifically exposure and ritual prevention; EX/RP) due to barriers such as a lack of EX/RP-trained clinicians, geographic obstacles, and the cost and time associated with the treatment. Offering an integrated treatment model consisting of brief in-person therapy coupled with a mobile application (app) might be one way to increase access to and reduce the time burden (to clinicians and patients) of EX/RP. This pilot trial evaluated the feasibility, acceptability, and clinical effects of such a treatment program for adults with OCD. Thirty-three participants enrolled in the 8-week open trial. The integrated treatment program consisted of 3 to 5 in-person sessions followed by weekly phone calls supported by a mobile app (nOCD). Participants were evaluated by trained raters and completed self-report measures at baseline, midtreatment, posttreatment and 2-month follow-up; the Yale-Brown Obsessive-Compulsive Scale (Y-BOCS) was the primary outcome. This integrated treatment program was feasible and acceptable to participants. Of the 33 study entrants, 14 (42%) responded to treatment (Y-BOCS decrease ≥35% with CGI- of 1 or 2), and 8 (24%) achieved minimal symptoms (i.e., Y-BOCS ≤12). At 2-month follow-up (n=20), 7/20 (35%) met criteria for treatment response, and 3/20 (15.0%) met criteria for treatment remission. Although preliminary, this model warrants further study as an efficacious and resource-efficient way to deliver EX/RP for some patients with OCD.

Compassion-Focused Group Therapy for Treatment-Resistant OCD: Initial Evaluation Using a Multiple Baseline Design

Obsessive-compulsive disorder (OCD) is a debilitating mental health disorder that can easily become a treatment-resistant condition. Although effective therapies exist, only about half of the patients seem to benefit from them when we consider treatment refusal, dropout rates, and residual symptoms. Thus, providing effective augmentation to standard therapies could improve existing treatments. Group compassion-focused interventions have shown promise for reducing depression, anxiety, and avoidance related to various clinical problems, but this approach has never been evaluated for OCD individuals. However, cultivating compassion for self and others seems crucial for OCD patients, given the accumulating research suggesting that fear of guilt, along with isolation and self-criticism, can strongly contribute to the development and maintenance of OCD. The primary aim of this pilot study was to evaluate the acceptability, tolerability, and effectiveness of an 8-week group compassion-focused intervention for reducing OCD symptoms, depression, fear of guilt and self-criticism, and increasing common humanity and compassionate self-reassuring skills in treatment-resistant OCD patients. Using a multiple baseline experimental design, the intervention was evaluated in a sample of OCD patients (N = 8) who had completed at least 6 months of CBT treatment for OCD, but who continued to suffer from significant symptoms. Participants were randomized to different baseline assessment lengths; they then received 8 weekly, 120-min group sessions of compassion-focused therapy for OCD (CFT-OCD), and then were tested again at post-treatment and at 1 month follow up. Despite the adverse external circumstances (post-treatment and follow-up data collection were carried out, respectively, at the beginning and in the middle of the Italian lockdown due to the COVID-19 pandemic), by the end of treatment, all participants demonstrated reliable decreases in OCD symptoms, and these improvements were maintained at 4-week follow-up for seven of eight participants. The intervention was also associated with improvements in fear of guilt, self-criticism, and self-reassurance, but less consistent improvements in depression and common humanity. Participants reported high levels of acceptability of and satisfaction with the intervention. Results suggest that the intervention may be beneficial as either a stand-alone treatment or as an augmentation to other treatments.

Acute Effects of Cannabis on Symptoms of Obsessive-Compulsive Disorder

BACKGROUND

Little is known about the the acute effects of cannabis on symptoms of OCD in humans. Therefore, this study sought to: 1) examine whether symptoms of OCD are significantly reduced after inhaling cannabis, 2) examine predictors (gender, dose, cannabis constituents, time) of these symptom changes and 3) explore potential long-term consequences of repeatedly using cannabis to self-medicate for OCD symptoms, including changes in dose and baseline symptom severity over time.

METHOD

Data were analyzed from the app Strainprint® which provides medical cannabis patients a means of tracking changes in symptoms as a function of different doses and strains of cannabis across time. Specifically, data were analyzed from 87 individuals self-identifying with OCD who tracked the severity of their intrusions, compulsions, and/or anxiety immediately before and after 1,810 cannabis use sessions spanning a period of 31 months.

RESULTS

Patients reported a 60% reduction in compulsions, a 49% reduction in intrusions, and a 52% reduction in anxiety from before to after inhaling cannabis. Higher concentrations of CBD and higher doses predicted larger reductions in compulsions. The number of cannabis use sessions across time predicted changes in intrusions, such that later cannabis use sessions were associated with smaller reductions in intrusions. Baseline symptom severity and dose remained fairly constant over time.

LIMITATIONS

The sample was self-selected, self-identified as having OCD, and there was no placebo control group.

CONCLUSIONS

Inhaled cannabis appears to have short-term beneficial effects on symptoms of OCD. However, tolerance to the effects on intrusions may develop over time.

Impact of the COVID-19 pandemic on exposure and response prevention outcomes in adults and youth with obsessive-compulsive disorder

The COVID-19 pandemic has created novel mental health challenges for those with pre-existing problems including obsessive-compulsive disorder (OCD). Our study reports on clinician perceptions regarding the effect of the COVID-19 pandemic on patients with OCD receiving exposure and response prevention treatment (ERP) prior to and during the pandemic. Participating clinicians completed a survey which included questions adapted from National Institute of Mental Health-Global Obsessive-Compulsive Scale (NIMH-GOCS) and Yale-Brown Obsessive-Compulsive Scale (Y-BOCS). Clinicians rated clinical features at treatment initiation, just prior to the pandemic, and mid-pandemic (July/August, 2020). Findings suggest that the COVID-19 pandemic was associated with attenuation of ERP progress from expected rates in most patients during first several months of the pandemic; clinicians estimated that 38% of their patients had symptoms worsen during the pandemic and 47% estimated that symptoms remained unchanged despite participating in ERP. Those who endured financial distress or were medically at-risk for severe COVID-19 disease had worse ERP course. Adults also had a worse ERP course during than pandemic than youth. Further research is needed to better understand the effect of the COVID-19 pandemic on OCD symptomatology and treatment trajectory post-pandemic.

A Preliminary Examination of Acceptance and Commitment Therapy Versus Exposure and Response Prevention for Patients with Obsessive-Compulsive Disorder on an Optimal Dose of SSRIs: A Randomized Controlled Trial in Iran

This study compared the effects of adding acceptance and commitment therapy (ACT) or exposure and response prevention (ERP) to adults diagnosed with obsessive compulsive disorder (OCD) already on an optimal and stable dose of selective serotonin reuptake inhibitors (SSRIs). Forty adults on SSRIs who were diagnosed with OCD participated in a randomized controlled trial in Iran of 12 individual weekly sessions of either ACT+SSRI, ERP+SSRI, or continued SSRI only. The results showed significant reductions in OCD symptom severity in ACT+SSRI and ERP+SSRI conditions at posttreatment with significantly greater reductions in both conditions compared to SSRI-only at follow-up. Additionally, psychological inflexibility and use of thought control strategies significantly decreased in the ACT+SSRI condition at posttreatment and follow-up compared to the ERP+SSRI and SSRI conditions. Both conditions led to decreases in perceived importance of stop signals. Results provide cross-cultural support for the treatment of OCD using ACT and ERP as adjuncts to SSRI and modest process of change differences between ACT and ERP. Future directions and study limitations are discussed.

Die Rolle von Verhaltensexperimenten in der Behandlung von Zwangsstörungen: Ein Update zur effektiven Gestaltung und Durchführung in der Praxis

Das Ziel des Artikels ist es, den neuesten Stand zum effektiven Einsatz von Verhaltensexperimenten im Rahmen der Psychotherapie für Zwangsstörungen darzulegen. Dazu werden im ersten Teil die evidenzbasierten Psychotherapien zur Behandlung von Zwangsstörungen vorgestellt sowie die Probleme bei der Implementierung dieser Verfahren aufgezeigt. Dabei zeigt sich, dass trotz der guten Evidenzlage die Verfahren zu selten eingesetzt werden und so die Forschungs-Praxis-Lücke fördern. Im Anschluss werden die zugrundeliegenden Rationale zur Durchführung von Verhaltensexperimenten erläutert, in Bezug zu aktuellen Forschungsarbeiten gestellt und damit die Bedeutung von Verhaltensexperimenten in der Therapie von Zwangsstörungen unterstrichen. Daraus werden Empfehlungen für die effektive Umsetzung von Verhaltensexperimenten in der Praxis abgeleitet. Die Funktionsanalyse der zwangsspezifischen Symptomatik stellt das zentrale Element im Rahmen der Behandlung von Zwangsstörungen dar. Dabei müssen die Verhaltensexperimente an die individuell befürchtete Konsequenz bei Unterlassen von Ritualen und Sicherheitsverhalten (d.h. die furchtbasierte Überzeugung) ausgerichtet sein, um eine maximale Erwartungsverletzung zu ermöglichen. Klinische Fallbeispiele werden skizziert, anhand deren effektive Verhaltensexperimente anschaulich und praxisnah dargestellt werden. Abschließend werden noch Hinweise, Tipps und Fallstricke für Praktiker zur Durchführung von effektiven Verhaltensexperimenten beleuchtet und die Grenzen von Verhaltensexperimenten benannt.

The Metacognitive Training for obsessive-compulsive disorder: A pilot study

More than 50% of patients with obsessive-compulsive disorder (OCD) do not receive first-line psychological treatment such as cognitive-behavioral therapy with exposure and response prevention. To narrow this treatment gap, there is an urgent need for therapies that are easy to disseminate and highly accepted by patients. The aim of the present pilot study was to evaluate the effectiveness of the Metacognitive Group Training for OCD (MCT-OCD). Fifty patients with OCD participated in the MCT-OCD for 4 weeks during their inpatient stay in a single-arm pilot trial. Patients were assessed before and after the intervention and filled out an online survey 6 months after post assessment. Results showed a decrease in obsessive compulsive symptoms according to the Yale-Brown Obsessive Compulsive Scale (primary outcome) from baseline to post assessment with a large effect size. Symptom reduction remained stable over 6 months and was positively correlated with appraisal ratings of the training. The reduction in frequency of obsessive compulsive symptoms, distress due to obsessive compulsive symptoms, cognitive biases, and depressive symptoms remained stable over 6 months after the intervention. Our findings tentatively imply that the MCT-OCD is a promising treatment for OCD patients. A randomized controlled trial is thus warranted to further clarify the efficacy of the MCT-OCD.

Long-term Outcomes of Intensive Inpatient Care for Severe, Resistant Obsessive-Compulsive Disorder: Résultats à long terme de soins intensifs à des patients hospitalisés pour un trouble obsessionnel-compulsif grave et résistant

OBJECTIVE

A substantial proportion of severely ill patients with obsessive-compulsive disorder (OCD) do not respond to serotonin reuptake inhibitors (SRIs) and are unable to practice cognitive behavioral therapy (CBT) on an out-patient basis. We report the short-term (at discharge) and long-term (up to 2 years) outcome of a multimodal inpatient treatment program that included therapist-assisted intensive CBT with adjunctive pharmacotherapy for severely ill OCD patients who are often resistant to SRIs and are either unresponsive or unable to practice outpatient CBT.

METHODS

A total of 420 patients, admitted between January 2012 and December 2017 were eligible for the analysis. They were evaluated using the Mini International Neuropsychiatric Interview, the Yale-Brown Obsessive Compulsive Scale (YBOCS), and the Clinical Global Impression (CGI) scale. All patients received 4 to 5 therapist-assisted CBT sessions per week along with standard pharmacotherapy. Naturalistic follow-up information at 3, 6, 12, and 24 months were recorded.

RESULTS

At baseline, patients were mostly severely ill (YBOCS = 29.9 ± 4.5) and nonresponsive to ≥2 SRIs (83%). Mean duration of inpatient stay was 42.7 ± 25.3 days. At discharge, there was a significant decline in the mean YBOCS score (29.9 ± 4.5 vs. 18.1 ± 7.7, P < .001, Cohen's d = 1.64); 211/420 (50%) were responders (≥35% YBOCS reduction and CGI-I≤2) and an additional 86/420 (21%) were partial responders (25% to 35% YBOCS reduction and CGI-I≤3). Using latent class growth modeling of the follow-up data, 4 distinct classes were identified, which include "remitters" (14.5%), "responders" (36.5%), "minimal responders" (34.7%), and "nonresponders" (14.6%). Shorter duration of illness, better insight, and lesser contamination/washing symptoms predicted better response in both short- and long-term follow-up.

CONCLUSION

Intensive, inpatient-based care for OCD may be an effective option for patients with severe OCD and should be considered routinely in those who do not respond with outpatient treatment.

The Psychopharmacology of Obsessive-Compulsive Disorder: A Preclinical Roadmap

This review evaluates current knowledge about obsessive-compulsive disorder (OCD), with the goal of providing a roadmap for future directions in research on the psychopharmacology of the disorder. It first addresses issues in the description and diagnosis of OCD, including the structure, measurement, and appropriate description of the disorder and issues of differential diagnosis. Current pharmacotherapies for OCD are then reviewed, including monotherapy with serotonin reuptake inhibitors and augmentation with antipsychotic medication and with psychologic treatment. Neuromodulatory therapies for OCD are also described, including psychosurgery, deep brain stimulation, and noninvasive brain stimulation. Psychotherapies for OCD are then reviewed, focusing on behavior therapy, including exposure and response prevention and cognitive therapy, and the efficacy of these interventions is discussed, touching on issues such as the timing of sessions, the adjunctive role of pharmacotherapy, and the underlying mechanisms. Next, current research on the neurobiology of OCD is examined, including work probing the role of various neurotransmitters and other endogenous processes and etiology as clues to the neurobiological fault that may underlie OCD. A new perspective on preclinical research is advanced, using the Research Domain Criteria to propose an adaptationist viewpoint that regards OCD as the dysfunction of a normal motivational system. A systems-design approach introduces the security motivation system (SMS) theory of OCD as a framework for research. Finally, a new perspective on psychopharmacological research for OCD is advanced, exploring three approaches: boosting infrastructure facilities of the brain, facilitating psychotherapeutic relearning, and targeting specific pathways of the SMS network to fix deficient SMS shut-down processes. SIGNIFICANCE STATEMENT: A significant proportion of patients with obsessive-compulsive disorder (OCD) do not achieve remission with current treatments, indicating the need for innovations in psychopharmacology for the disorder. OCD may be conceptualized as the dysfunction of a normal, special motivation system that evolved to manage the prospect of potential danger. This perspective, together with a wide-ranging review of the literature, suggests novel directions for psychopharmacological research, including boosting support systems of the brain, facilitating relearning that occurs in psychotherapy, and targeting specific pathways in the brain that provide deficient stopping processes in OCD.
