Nowadays, disruptive behaviour disorders and substance use disorders are issues frequently identified among adolescents and may have adverse effects on adolescents' lives and eventually lead to catastrophic consequences if people fail to address them in time. In China, the number of juvenile offenders under eighteen has also increased for the past 15 years. However, the laws and regulations in China are not sufficiently detailed and specific, so the actual implementation of community correction is not effective enough. Functional Family Therapy (FFT) is an evidence-based family therapy for pre-adolescents and adolescents (10-18 years) to treat their behavioural problems and substance misuse, which is widely implemented in Western countries. So, this article aims to explore the implementation of FFT in China by following the National Implementation Research Network (NIRN) and considering the reality of China, to try to help Chinese adolescents and society in the future.
