Imagery Rescripting (ImRs) as an Adjunctive Treatment to Exposure and Response Prevention (ERP)-Resistant Obsessive-Compulsive Disorder: A Case Study

Abstract

Exposure and response prevention (ERP), a specific type of Cognitive and Behaviour Therapy, is well recognised as the first-line psychological treatment in obsessive-compulsive disorder (OCD), either alone or in combination with selective serotonin reuptake inhibitor pharmacotherapy. However, given that up to half of patients suffering from OCD do not experience a clinically significant reduction in symptoms following ERP, further treatment options for treatment-resistant OCD are needed. Initial research into using ImRs as a psychological adjunct for treatment-resistant OCD has been encouraging. We provide a detailed case study of a 61-year-old male who continued, following ERP treatment, to suffer debilitating OCD symptoms of compulsive checking to prevent making mistakes. Following ERP, the individual received two sessions of ImRs as a therapy adjunct, which resulted in a further reduction of 56% in OCD symptoms. The individual reported associated improvements in mood, life satisfaction, and occupational and interpersonal relationships. This case study describes how ImRs can be incorporated into ERP treatment for OCD. Details of the ERP and ImRs treatment are provided, along with transcript excerpts to highlight the ImRs process. Further research is needed to enhance understanding of mechanisms and optimal deployment of ImRs in treatment sequencing for OCD sufferers.
