In order to determine the prevalence and characteristics of childhood physical and sexual abuse in China, the authors conducted a survey in Shanghai. The Dissociative Disorders Interview Schedule was administered to 423 inpatients and 304 outpatients at Shanghai Mental Health Center, and to a non-clinical sample of 618 workers at a clothing factory. The results were compared to a previous sample of 502 respondents in the general population in Winnipeg, Canada. The identities of the perpetrators of physical and sexual abuse, and the types of sexual abuse reported were similar in the two countries; however, the rates of reported abuse were lower in China. Childhood sexual abuse appears to be far less common in the general population in Canada than in China. (Contains 4 tables.)
