Abstract

Background: Psychotic experiences (PE) may co-occur with common mental disorders (CMD), such as depression and anxiety. However, we know very little about the prevalence of and recovery from PE in primary mental health care settings, such as the Improving Access to Psychological Therapies (IAPT) services in the UK National Health Service (NHS), where most CMD are treated.

Methods: We used the Community Assessment of Psychic Experiences - Positive 15-item Scale (CAPE-P15) to determine the prevalence of PE in patients receiving treatment from IAPT services. Patient-reported measures of depression (PHQ-9) and anxiety (GAD-7) are routinely collected and establish recovery in IAPT services. We studied recovery rates according to the absence and presence of PE. Multi-group growth models estimated improvement trajectories for each group.

Results: 2,042 patients with CMD completed the CAPE-P15. The mean age was 39.8. The overall prevalence of PE was 29.68%. The recovery rate was 27.43% compared to 62.08% for those without PE. Although patients with or without PE shared similar improvement trajectories, the initial severity of patients with PE impeded their likelihood of recovery.

Limitations: We mirrored routine data collection in IAPT services, including self-report questionnaires that may affect valid reporting of symptoms. Missing data in the calculation of improvement trajectories may reduce generalisability.

Conclusions: At least one in four patients receiving treatment from IAPT services in primary care experience CMD and PE. This significant group of people experience a lower recovery rate, with adverse implications not only for them but also for efficiency of services.
