Abstract. Despite a strong evidence base for cognitive behavioural therapy (CBT)
for obsessive compulsive disorder (OCD), there is limited evidence regarding the
effectiveness of group therapy compared to individual therapy. As services struggle
to manage high demands, CBT for OCD is often offered in group format. This paper
examines the current evidence base for group CBT for OCD considering both clinical
outcomes and cost, and describes a group CBT intervention for people with OCD. A
CBT group was set up, consistent with NICE guidelines, but slightly adapted from
standard group protocols, in line with recommendations from experts in the field. It
was evaluated as part of an audit of the service. Statistical analyses demonstrated
significant improvements in both measures of depression and the impact of difficulties,
and on specific measures of OCD, in clients who attended group CBT (n = 17). The
analyses also demonstrated improved effectiveness of therapist hours for group therapy
compared to individual therapy. It is concluded that group therapy for OCD should be
considered as an alternative to individual therapy when there are significant demands
on the service. Recommendations regarding specific adaptations to the standard group
CBT format are made.
