Studied the content and characteristics of auditory hallucinations reported by 75 20-65 yr old schizophrenic in- and out-patients receiving antipsychotic medication living in Saudi Arabia and the UK. Each S was interviewed and given a self-report questionnaire. They were asked to report on the content and characteristics of their hallucinations with regard to parameters such as loudness, frequency, difficulty in ignoring the voices, apparent validity, source and perceived reality of the voices. In general, the characteristics of the voices did not vary between Ss in Saudi Arabia and UK, but the content differed between cultures. Much of the content of the hallucinations of Saudi Arabian Ss were religious and superstitious in nature, whereas instructional themes and running commentary were common in the UK Ss. The results suggest that cultural differences need to be taken into account when applying psychological methods to different group of patients.
