Abstract

Aim: The prevalence of psychotic-like experiences (PLEs) was explored in a sample of 14- to 25-year-olds with non-psychotic mental health difficulties. Associations between PLEs, psychopathology, functioning, trauma history, and pathways to care were examined.

Methods: Data were collected for 202 young people. Clinicians rated PLEs using the Primary Care Checklist (PCC) and functioning using Global Assessment Scales. Eighty-three young people completed self-report assessments of PLEs using the Prodromal Questionnaire (PQ-16) and measures of social anxiety, depression, trauma history, and pathways to care.

Results: There was a high prevalence of PLEs in the sample. The prevalence of PLEs was higher when young people self-rated their experiences. Endorsement frequencies for PLEs ranged from 3.5 to 24% on the PCC and 22 to 70% on the PQ-16. Higher scores on the PQ-16 were associated with more pathways into care and greater exposure to traumatic life events.

Conclusions: PLEs are common in young people with non-psychotic mental health difficulties and may reflect increased severity and complexity of mental health difficulties. Routine screening and further assessment of PLEs are important in understanding and responding to such experiences. Screening should include self-rating of PLEs as well as clinician-rated scales.
