This qualitative study collected stakeholders’ views on adapting an existing online psychotherapy programme, ‘Tame Your Gut’, to the needs of patients with inflammatory bowel disease (IBD) and comorbid anxiety and/or depression. Adult patients ( n = 13) and health professionals ( n = 12) participated in semi-structured focus groups or interviews, analysed with a thematic analysis. Patients had a generally positive attitude towards ‘Tame Your Gut’, while health professionals saw it as useful for selected patients only. Both groups indicated their preference for clinician-assisted online psychotherapy. ‘Tame Your Gut’ is acceptable to patients and health professionals but only when supported by clinicians.
