Auditory hallucinations in pre-pubertal children. A one-year follow-up, preliminary findings.

Background: The aims of this study were to describe the phenomenology of auditory hallucinations in children, to establish links with DSM IV diagnoses and to explore development of the hallucinations over a 12-month period.

Methods: Outpatients aged 5- to 12-year-old were consecutively recruited. They were interviewed using a questionnaire investigating auditory hallucinations. DSM IV diagnoses were determined. Follow-up assessments were performed at 3, 6, 9 and 12 months.

Results: Ninety children were recruited. Sixteen reported auditory hallucinations. In 53% we observed children's full recovery from hallucinations within 3 months and all of these suffered from anxiety disorders. In 30% hallucinations persisted over 12 months and all showed conduct disorders at this point in time. None was diagnosed as having schizophrenia.

Conclusions: Our study provides further evidence of the high prevalence of auditory hallucinations in pre-pubertal children presenting to psychiatric clinics. Two different patterns of development were seen. In one group the hallucinations seem unrelated to psychosis although they may be a manifestation of anxiety. In the second, much smaller, persistence of hallucinations appeared linked to conduct disorders.
