Data for paper published in PLOS One October 2020

There are 3 data files:

1. Extracts from interviews with MBCT for OCD participants

2. Extracts from interviews with MB-ERP participants

3. Content analysis of changes reported from MBCT for OCD and MB-ERP participants


Cognitive behavioural therapy (CBT) which includes Exposure and Response (ERP) is a highly effective, gold standard treatment for Obsessive-Compulsive Disorder (OCD). Nonetheless, not all patients with OCD significantly benefit from CBT. This has generated interest in the potential benefits of Mindfulness-Based Interventions (MBIs), either integrated with CBT, to enhance engagement with ERP tasks, or delivered as a stand-alone, first-line or therapy to augment CBT. This paper reports on two qualitative studies that involved a thematic analysis of interview data with participants in a 10-week Mindfulness-Based ERP (MB-ERP) course (study 1) and a 9-week Mindfulness-Based Cognitive Therapy course adapted for OCD (MBCT-OCD) (study 2). Whilst MB-ERP integrated a mindfulness component into a standard ERP protocol, MBCT-OCD adapted the psychoeducational components of the standard MBCT for depression protocol to suit OCD, but without explicit ERP tasks. Three common main themes emerged across MB-ERP and MBCT-OCD: ‘satisfaction with course features’, ‘acceptability of key therapeutic tasks ‘and ‘using mindfulness to respond differently to OCD’. Sub-themes identified under the first two main themes were mostly unique to MB-ERP or MBCT-OCD, with the exception of ‘(struggles with) developing a mindfulness practice routine’ whilst most of the sub-themes under the last main theme were shared across MB-ERP and MBCT-OCD participants. Findings suggested that participants generally perceived both MBIs as acceptable and potentially beneficial treatments for OCD, in line with theorised mechanisms of change.
