[Comparison of the content of delusions of schizophrenics in China and Japan: cross-cultural psychiatric investigation].
A comparative cross-cultural psychiatric study was carried out in order to evaluate the theme of delusions of the present day between China and Japan in schizophrenia in relation to their socio-cultural background. The data base was comprised of the schizophrenic cases with the first admission in each hospital--Shanghai in the period 1983, Tokyo in the period 1981-1983 (Shanghai 200 cases, Tokyo 186 cases), and the analysis was focused on those cases with delusions (Shanghai: 129 cases with 70 male and 59 female; Tokyo: 112 cases with 53 male and 59 female). The incidence of delusions with persecution, reference, physical persecution and grandeur was relatively high in patients in Shanghai or Tokyo, while the incidence of delusions with hypochondriacal and guilt was low in both hospitals. Only the incidence of delusion of poisoning was significantly higher in Shanghai than in Tokyo (chi 2 = 12.97, P less than 0.001). The authors have discussed the influence of social-cultural background on the formation of delusions of poisoning, persecution, grandeur, descent and possession about two countries.
