Effectiveness of One Videoconference-Based Exposure and Response Prevention Session at Home in Adjunction to Inpatient Treatment in Persons With Obsessive-Compulsive Disorder: Nonrandomized Study.

BACKGROUND: Therapist-guided exposure and response prevention (ERP) for the treatment of obsessive-compulsive disorder (OCD) is frequently conducted within clinical settings but rarely at places where patients are usually confronted with OCD symptom-provoking situations in daily life (eg, at home). OBJECTIVE: This study aimed to investigate patients' views on 1 ERP session at home via videoconference and its impact on treatment outcome. METHODS: A total of 64 inpatients with OCD received 1 session of therapist-guided videoconference-based ERP at home in adjunction to a multimodal inpatient treatment between 2015 and 2020. RESULTS: Compared with 64 age- and sex-matched controls who received a multimodal inpatient treatment without 1 session of videoconference-based ERP at home, patients who received 1 session of videoconference-based ERP in adjunction to a multimodal inpatient treatment showed stronger reductions in OCD symptom severity from admission to discharge. Before the videoconference-based ERP session, patients reported high rationale credibility and treatment expectancy. After the videoconference-based ERP session, patients reported medium-to-high positive mood as well as depth and smoothness of the session, and they perceived the working alliance as high. CONCLUSIONS: Results highlight the importance of administering therapist-guided ERP sessions in patients' natural environment to enhance treatment response in OCD. Videoconference-based ERP as add-on to treatment as usual is, therefore, a promising approach to facilitate the application of ERP in patients' natural environment and foster the generalization of ERP conducted in clinical settings.

Usability and Naturalness of Videoconference-Based Exposure and Response Prevention for Obsessive-Compulsive Disorder at the Patients' Homes: A Pilot Study.

The treatment of choice for obsessive-compulsive disorders is cognitive behavioral therapy, including exposure and response prevention (ERP). Therapist-supervised ERP is more effective than self-controlled ERP, and exposure should take place at the patient's home. This standard might be achieved with ERPs at home via videoconference supervision from the therapist. The aim of this study was to (a) assess the usability and naturalness of videoconference exposure and (b) to compare it with face-to-face exposure at an inpatient clinic and exposure at home alone regarding therapeutic alliance, patients' expectancies, and credibility of the treatment and an overall rating of the exposure session. Mean differences and effect sizes suggested a slight general advantage of videoconference-based ERP and the interaction with the therapist felt natural to the participants. The technical system was rated as medium usable, suggesting a need for better training.
