Limitations
auditory hallucinations, Auditory hallucinations
The main limitation of the study was that the primary goal of the SEYLE study was to examine the effectiveness of interventions for suicidal behaviour, rather than PEs. Only the Irish sites used PEs as a measure, limiting the numbers involved. Additionally, due to the random sampling design, more individuals with PEs at baseline happened to be in the schools which were assigned to the ProfScreen arm. This was controlled for in analysis, but with a larger sample of schools i.e. the whole SEYLE sample, this random imbalance was unlikely to have occurred. Finally, PEs were measured using a single item (auditory hallucinations). Auditory hallucinations been shown have good clinical and construct validity for measuring PEs [Another consideration is a selective intervention approach can lead to stigma [
