What is the purpose of this trial?

This trial aims to enhance the effectiveness of exposure therapy for individuals with Obsessive Compulsive Disorder (OCD). Researchers seek to identify specific techniques during therapy sessions that lead to the best outcomes. Participants will undergo exposure therapy, which involves confronting anxiety triggers in a controlled manner, and will provide feedback on their experiences. The trial is suitable for adults with OCD seeking exposure therapy at McLean Hospital or San Diego State University. As an unphased trial, this study offers participants the chance to contribute to groundbreaking research that could improve therapy techniques for OCD.

Will I have to stop taking my current medications?

The trial information does not specify whether you need to stop taking your current medications. It's best to discuss this with the trial coordinators or your doctor.

What prior data suggests that exposure therapy is safe for OCD patients?

Research has shown that exposure therapy, especially when combined with response prevention, is a proven treatment for obsessive-compulsive disorder (OCD). Studies have found it effective and generally safe in both hospital and outpatient settings. For example, one study found that this method helped patients manage their OCD symptoms well.

While exposure therapy is considered safe, some people might feel uncomfortable during sessions. This discomfort arises because the therapy involves facing things that trigger OCD symptoms. However, these feelings are usually temporary and are part of the process to help reduce anxiety over time.

Overall, exposure therapy is well-tolerated, and no significant evidence of long-term negative effects exists. For those considering joining a trial, it is reassuring to know that this treatment has a strong safety record. ^{1 2 3 4 5}

Why are researchers excited about this trial?

Researchers are excited about this trial because it explores a personalized approach to exposure therapy for OCD. Unlike standard treatments like cognitive-behavioral therapy with exposure and response prevention (ERP), this method involves developing exposure plans collaboratively with participants, tailoring the treatment to their specific needs. Additionally, the use of a wristwatch that gathers psychophysiological data is a novel feature, potentially offering real-time insights into patients' responses and allowing for more precise adjustments. This trial aims to refine exposure therapy practices, potentially enhancing its effectiveness and accessibility for individuals struggling with OCD.

What is the effectiveness track record for exposure therapy in treating OCD?

Research shows that exposure therapy, which participants in this trial will receive, effectively treats obsessive-compulsive disorder (OCD). Studies have found it greatly reduces OCD symptoms. One study found that symptoms improved significantly when exposure therapy was combined with medication, demonstrating a powerful combined approach. Another study found that exposure therapy alone had a moderate effect on reducing OCD symptoms. Overall, exposure therapy is a proven method, but there is still room for improvement for those who don't fully recover. ^{1 2 3 6 7}

Interventions

• Exposure Therapy

Trial Overview

The study aims to identify key mechanisms that make exposure therapy effective for treating OCD by analyzing self-reported data, observer-rated behavior, and physiological responses like heart rate during therapy sessions.

How Is the Trial Designed?

Group I: Exposure therapy Experimental Treatment 1 Intervention

Participants will complete exposure therapy for up to 12 weeks, and each coached exposure session will be approximately 50 minutes. Exposure plans will be developed collaboratively between participants and their clinician at the beginning of treatment, and refined iteratively as clinically appropriate. In each coached exposure, participants will: 1. Complete an Exposure Feedback Form 2. Wear a wristwatch that provides psychophysiological data The intervention will occur across two study sites (McLean Hospital, San Diego State University). Sites will differ on level of care. At McLean Hospital, participants will be recruited from the OCD Institute and will receive exposure therapy via partial hospital or residential setting as part of their standard care, regardless of participation in the study. At San Diego State University, participants will be recruited to receive exposure therapy via outpatient setting.

Published Research Related to This Trial

In a study involving 42 OCD patients, Concentrated Exposure Treatment (cET) led to a significant reduction in OCD symptoms, with 74% of participants achieving remission immediately after treatment and 60% maintaining recovery at a 6-month follow-up.

The treatment was well-received, showing high patient satisfaction, and the effectiveness of cET was successfully replicated with a new group of therapists, indicating its potential for broader use in treating OCD.

Exposure therapy with response prevention is considered the most effective treatment for obsessive-compulsive disorder (OCD), highlighting its importance in managing this condition.

This therapy has been successfully applied to both outpatient and inpatient settings, demonstrating its versatility and effectiveness across different patient populations.

A study involving 160 active-duty military personnel with PTSD found that 60-minute prolonged exposure (PE) therapy sessions are just as effective as the standard 90-minute sessions, making treatment more accessible in settings that typically use shorter appointment times.

Both the Clinician Administered PTSD Scale (CAPS-5) and the PTSD Checklist (PCL-5) showed that the efficacy of 60-minute sessions was noninferior to 90-minute sessions, suggesting that shorter sessions can be effectively implemented without compromising treatment outcomes.

A study of 30 patients who underwent 12 weeks of intensive inpatient cognitive behavioral therapy (CBT) with exposure and response prevention (ERP) showed significant long-term improvements in obsessive-compulsive disorder (OCD) symptoms, with 20% achieving remission 8-10 years post-treatment.

Continuing exposure exercises after the inpatient treatment was identified as a key factor for maintaining these improvements, suggesting that ongoing practice is essential for long-term success in managing OCD.

Serious negative consequences (SNC) from exposure and response prevention (ERP) therapy for obsessive-compulsive disorder (OCD) are extremely rare, occurring in only 0.05% of adult clients and 0.01% of youth clients, indicating that ERP is a safe treatment option.

Despite some therapists' concerns, the study found that most therapists are willing to treat harm-related OCD, and improving communication about the safety and rationale of ERP could enhance access to this effective therapy.

A 10-session group therapy for obsessive-compulsive disorder (OCD) was effective, showing a significant reduction in symptoms as measured by the Yale-Brown Obsessive-Compulsive Scale, with scores decreasing from 21.8 to 16.6 after treatment.

This group therapy approach offers a practical alternative to traditional individual therapy, addressing the challenges of limited access to trained therapists and the high costs associated with intensive individual treatment.

A survey of 216 German therapists revealed that while most consider exposure with response prevention (ERP) an effective treatment for obsessive-compulsive disorder (OCD), many do not implement it due to factors like patient motivation and organizational difficulties.

Differences were noted between physicians and psychologists, with physicians using ERP less frequently and preferring self-help methods, highlighting a need for improved adherence to treatment guidelines for OCD.
