ERP to Improve Functioning in Veterans With OCD

Официальное название

Exposure and Response Prevention to Improve Functioning in Veterans With Obsessive Compulsive Disorder

Обзор

Obsessive compulsive disorder (OCD) is a debilitating psychiatric illness impacting work, social, and family functioning. Exposure and Response Prevention (ERP) is the sole evidence-based psychotherapy for OCD; however, no randomized controlled trials (RCTs) have examined the effectiveness of ERP among Veterans or individuals with both OCD and posttraumatic stress disorder (PTSD). This 4-year Hybrid Type I trial will compare outcomes of ERP to those of a control condition among Veterans with OCD. Primary and secondary aims will examine whether Veterans' functioning, quality of life, and OCD symptoms differ between the ERP and control in the full sample of Veterans with OCD, and in the half of the sample with both OCD and PTSD. The tertiary aim is to conduct a mixed-methods formative evaluation of the implementation potential of ERP in VA mental health settings.

Подробное описание

The proposed 4-year multisite RCT will compare outcomes of VTH-delivered ERP to those of a stress management training control condition among 160 Veterans with OCD. Half of the sample with have comorbid PTSD. The primary aim will examine whether participants' functioning, quality of life, and OCD symptoms differ as a function of the intervention (ERP vs. control). The secondary aim will examine these outcomes among the half of the sample with comorbid OCD and PTSD. The tertiary aim is to conduct a mixed-methods formative evaluation of the implementation potential of ERP in VA mental health settings.

Eligible Veteran participants will be randomized to ERP or to the control condition. Veterans randomized to ERP will receive 16 weekly ERP sessions delivered via VTH. Control participants will receive 16 weekly sessions of a stress management training intervention delivered via VTH. Participants in both conditions will complete assessments at post-treatment and 6 months after completing treatment. Participants in the ERP condition will also complete an assessment of treatment satisfaction and a qualitative exit interview assessing the Veterans' perceptions of the impact of treatment on multiple domains of functioning, including the impact on PTSD symptoms. Providers and VA administrators will participate in qualitative interviews regarding the implementation potential of ERP in VA.

• Поведенческое Exposure and Response Prevention
  ERP is a specialized cognitive behavioral intervention conducted over the course of 8-16 therapy sessions. ERP is based upon exposure principles and the idea that people can habituate to the distress caused by OCD triggers and learn to cope with anxiety about feared consequences without engaging in compulsive behaviors to 'neutralize' the obsession. ERP begins with psychoeducation about OCD and exposure, followed by construction of a hierarchy, or list, of situations that are feared, avoided, or

  The stress management training intervention will be based on that delivered by Simpson in an ERP trial. It will be delivered by PhD and Master's level therapists from each site's clinics. The stress management training intervention will begin with an introductory session providing psychoeducation about OCD, followed by 15 sessions covering stress management skills such as deep breathing progressive muscle relaxation, positive imagery, assertiveness training, and problem solving. Each session wil
