Importance: Serotonin reuptake inhibitors (SRIs) are the only medications approved for obsessive-compulsive disorder (OCD), yet most patients taking SRIs exhibit significant symptoms. Adding exposure/response prevention (EX/RP) therapy improves symptoms, but it is unknown whether patients maintain wellness after discontinuing SRIs.

Objective: To assess whether patients with OCD who are taking SRIs and have attained wellness after EX/RP augmentation can discontinue their SRI with noninferior outcomes compared with those who continue their SRI therapy.

Obsessive-compulsive disorder (OCD), a frequently disabling disorder characterized by distressing thoughts and behaviors, often goes undetected, or individuals with this disorder do not receive evidence-based care. Educating clinicians and individuals with OCD and their families about OCD is a necessary first step to improving quality of care. This Open Forum describes the creation of a workforce development program named Improving Providers' Assessment, Care Delivery, and Treatment of OCD (IMPACT-OCD).

Practice guidelines for adults with obsessive-compulsive disorder (OCD) recommend augmenting serotonin reuptake inhibitors (SRIs) with exposure and ritual prevention (EX/RP). However, fewer than half of patients remit after a standard 17-session EX/RP course. We studied whether extending the course increased overall remission rates and which patient factors predicted remission.

Obsessive-compulsive disorder (OCD), a disabling psychiatric illness, creates substantial societal burden. Evidence-based treatments, including psychopharmacology and exposure with response/ritual prevention (EX/RP), are often inaccessible. Digital health technologies, including videoconferencing, may increase access, but the best way to integrate them with current treatments remains unclear.

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.

Pregnancy and postpartum periods are associated with increased risk for onset and exacerbation of obsessive-compulsive disorder (OCD) symptoms. Common themes of the obsessive thoughts in this period are fears of accidently or intentionally harming the baby. Postpartum OCD may go underdiagnosed or misdiagnosed due to lack of standardized screening and potential shame associated with reporting these symptoms.

Importance: Dimensional definitions of transdiagnostic mental health problems have been suggested as an alternative to categorical diagnoses, having the advantage of capturing heterogeneity within diagnostic categories and similarity across them and bridging more naturally psychological and neural substrates.

Objective: To examine whether a self-reported compulsivity dimension has a stronger association with goal-directed and related higher-order cognitive deficits compared with a diagnosis of obsessive-compulsive disorder (OCD).

Design, Setting, And Participants: In this cross-sectional study, patients with OCD and/or generalized anxiety disorder (GAD) from across the United States completed a telephone-based diagnostic interview by a trained rater, internet-based cognitive testing, and self-reported clinical assessments from October 8, 2015, to October 1, 2017.

Exposure and ritual prevention (EX/RP) is an effective first-line treatment for obsessive-compulsive disorder (OCD), but only some patients achieve minimal symptoms following EX/RP. Herein, we investigate whether task-based neural activity can predict who responds best to EX/RP. Unmedicated adult patients with OCD ( = 36) and healthy participants ( = 33) completed the Simon Spatial Incompatibility Task during high-resolution, multiband functional MRI (fMRI); patients were then offered twice-weekly EX/RP (17 sessions).

Objective: To systematically review outcomes from randomized controlled trials (RCTs) of mind-body treatments for PTSD.

Methods: Inclusion criteria based on guidelines for assessing risk of bias were used to evaluate articles identified through electronic literature searches.

Results: Twenty-two RCTs met inclusion standards.

Background: Many individuals with obsessive-compulsive disorder (OCD) display behavioral avoidance related to their obsessional thoughts and compulsive behaviors. However, how these avoidance behaviors impact treatment outcomes with exposure and response prevention (EX/RP) remains unclear. We examined pretreatment avoidance behaviors as predictors of EX/RP outcomes.

Social anxiety disorder (SAD) is one of the most prevalent psychiatric disorders in the United States. Although evidenced-based behavioral treatments are available, less than 20% of those with SAD receive treatment. Internet-based interventions can address barriers to treatment access, and guided Internet-based treatments have been demonstrated to be effective for SAD.

Over the past 15 years, technology has increasingly been incorporated into the provision of psychotherapy with studies emerging demonstrating the effectiveness of such models. However, randomized controlled trials remain scant and little is known about the impact of computer technology on the therapeutic alliance. The studies reported in this section are among the first randomized clinical trials of computer-assisted or internet-based therapies.

Objective: To use a Progressive Ratio (PR) computerized "work" paradigm to measure course and correlates of exercise motivation in in-patients with Anorexia Nervosa (AN).

Method: Sixteen inpatients with AN participated in a PR task assessing the relative reinforcing effect of two different increments of cash versus the opportunity to exercise for upto 30 min, twice; at low weight, and, for n = 10 participants, after weight restoration.

Results: There was a trend toward a higher work for exercise with 2 versus 5 increments of cash as the alternative reinforcer.
