Background In a baseline study among 7- and 8-year-oid children with auditory vocal hallucinations, only limited functional impact was observed. Aims To assess 5-year course and predictors of auditory vocal hallucinations, as well as 5-year incidence and its risk factors. Method A sample of 337 children, 12 and 13 years of age, were reassessed on auditory vocal hallucinations and associated symptoms after a mean follow-up period of 5.1 years. Results The 5-year persistence and incidence rates were 24% and 9% respectively, with more new cases arising in urban areas. Both persistent and incident auditory vocal hallucinations were associated with problem behaviour in the clinical range of psychopathology as measured with the Child Behavior Checklist, particularly at follow-up, as well as with other psychotic symptoms, particularly at baseline. Persistence was predicted by baseline auditory vocal hallucinations severity, particularly in terms of external attribution of voices and hearing multiple voices, and was associated with worse primary school test scores and lower secondary school level. Conclusions First onset of auditory vocal hallucinations in middle childhood is not uncommon and is associated with psychopathological and behavioural comorbidity. Similarly, persistence of auditory vocal hallucinations in childhood is not uncommon and is associated with psychopathological, behavioural and cognitive alterations. Declaration of interest None.
