Cognitive behavior therapy(CBT) is one of the most widely used psychotherapy methods in the world.However, its origin in Western culture makes many researchers doubt whether it can be effectively applied to other cultural groups.The discussion on this issue is conducive to further adjusting CBT from an international perspective to better serve different cultural groups.This review focuses on the research progress of acculturation in CBT at home and abroad.Firstly, it discusses the necessity of acculturation and introduces the relevant major researchers in this field abroad, so as to explain how to carry out the work of acculturation.Then the effectiveness of current acculturation work is demonstrated, and the research progress of acculturation related to Chinese culture is introduced emphatically.In previous studies, most scholars supported the development of acculturation, and preliminary evidence has shown that CBT after acculturation has equal or even better effectiveness.Based on this, different researchers have put forward their own acculturation framework or adaptation suggestions.However, there are still many shortcomings in current research, which are mainly reflected in six aspects: few comparative studies, lack of unified framework, blank fields in some areas, shallow level of acculturation, unknown mechanism and lack of bottom-up research.Thus, this review is aimed to point out the urgency and necessity of CBT cultural adaptation in China, and put forward some suggestions and preliminary ideas for the further development of more culturally adaptable CBT in China, in order to better promote the application of CBT in China.
