A questionnaire study of hostility in persistent auditory hallucinators.

Twenty-six psychotic patients selected for persistent auditory hallucinations were tested on the HDHQ Questionnaire. Their total hostility scores were found to be significantly higher than those of the mixed schizophrenic normative sample, suggesting a link between aggressive tendencies and auditory hallucinations. The total sample was further subdivided on the basis of duration, location and quality of voices, and subgroup comparisons undertaken. These suggested that location and quality of voices were independent of each other and differentially linked with other measures. Several hypothesis for further investigation were generated.
