The study found that 34 percent of the children in the sample had been exposed to child physical abuse (CPA). The prevalence of full post-traumatic stress disorder (PTSD) among the sample was estimated to be 13.6 percent, while partial PTSD was estimated to be 16.9 percent. This study investigated the prevalence of CPA among a sample of adolescents in Taiwan, taking into account the more rigorous definitions of CPA within Chinese societies. Data for the study were obtained from a sample of 4th through 8th grade adolescents (n=1,966) who were administered the Chinese version of the UCLA PTSD Reaction Index for DSM-IV to investigate the lifetime exposure to CPA. The study results indicate that the prevalence of CPA in Taiwanese adolescents was greater than that found in Western countries, but less than what had been found in previous studies conducted in East Asian countries. These results indicate the significance of considering cultural background in defining CPA and examining CPA-related PTSD in children. Implications for future research are discussed.
