Research summary
The Improving Access to Psychological Therapy (IAPT) service treats nearly a million people annually. However, recovery rates are lower than anticipated, especially for people with common mental disorder including psychotic experiences, such as paranoia or voice hallucinations. This study is part of the wider TYPPEX (Tailoring evidence-based psychological therapY for People with common mental disorder including Psychotic Experiences) programme, which aims to address the unmet need of service users who experience, but do not necessarily disclose, psychotic phenomena.
This feasibility study will train 8-10 therapists in each of three teams within the IAPT service (one team per mental health Trust). The training package will support therapists to deliver care to service users with psychotic experiences and common mental disorder; people who have scored above a threshold on the Community Assessment of Psychic Experiences (CAPE) questionnaire, referred to as CAPE+. Following training, therapists will treat an average of 3 CAPE+ service users each.
A total of 45 CAPE+ service users will be asked to consent to the collection of health economic data via online questionnaires at baseline (therapy session 2), then at 3 months and 6 months after that. Routine clinical data for all CAPE+ service users will be provided by the Trusts to the Norwich Clinical Trials Unit in an anonymised form.
In this feasibility study, we will assess the viability of recruiting, training and supervising therapists, and their use of TYPPEX strategies. The most feasible and effective methods of collecting health economic data from service users will be assessed. Clinical and health economic data collected in the feasibility study will inform the design of the TYPPEX randomised controlled trial, which will test the hypothesis that care delivered to CAPE+ IAPT users by TYPPEX-trained therapists will be more effective and cost-effective than treatment-as-usual in IAPT services.
