Blended individual and group CBT for OCD in adolescents: model description and a feasibility study

Cognitive-behavioural treatment for obsessive-compulsive disorder (OCD) is effective across the lifespan but is not widely available across the range of services. Delivering CBT as a blended treatment combining individual and group-based treatment with flexible parental involvement, adapted to the operational style of any particular service, is a promising option which we aimed to examine in OCD with adolescent samples. In a young people's service based in a University Hospital, we evaluated the impact of a blended treatment combined with flexible parental involvement with adolescents (age 14-18 years of age). The CBT model used with OCD sufferers was a formulation driven approach, emphasising the importance of providing an alternative account linked to the way responsibility beliefs lead to compulsive behaviour. Six consecutively referred adolescents with their parents participated in a treatment group. Intervention consisted of eight individual meetings, eight group meetings and two meetings with parents. Five of six adolescents carried out the whole intervention. Of all participants, 5/5 scored in the clinical range for OCD at baseline, and 5/5 were no longer in the clinical range by the end of treatment; 5/5 were in the clinical range on general psychiatric problems at baseline, and 4/5 were rated as recovered at the end of treatment. Comparable changes were noted in measures of responsibility linked to intrusive thoughts. Use of a blended individual/group treatment based on a CBT model is feasible, with the results obtained being consistent with previous work on individual CBT treatment. Key learning aims (1) Delivering CBT to adolescents with OCD as a blended treatment combining individual and group-based treatment with flexible parental involvement is a promising option which merits further evaluation. (2) OCD symptoms and general psychiatric symptoms were reduced during and after treatment. (3) Use of a blended treatment based on a CBT model is feasible.
