Objective: To describe and record the evolution of EBM in China. Study Design and Setting: We conducted the study following the general methodology of oral history. The interviews were done at Lanzhou University, between 18th and 22 nd April 2019 using pre-defined questions. All interviews were videorecorded. Two investigators extracted and analyzed the information from the interviews independently. Results: One international expert and ten Chinese experts participated in the interviews. After the introduction of EBM in China in the mid-1990s, more than 20 EBM centres have been established. According to the interviewees, Gordon Guyatt, David Sackett and lain Chalmers are the international experts who played the most important role in the development of EBM in China. China has contributed to EBM on the international level by conducting systematic reviews, developing reporting checklists, and introducing the principles of EBM into Traditional Medicine. The Chinese Cochrane Centre and the EBM Centre of Lanzhou University were ranked the top two EBM Centres in China by the interviewees. Conclusion: EBM has been developing in China for nearly a quarter of a century. Many achievements have been reached, however, EBM is still facing many challenges in China, including shortages of funding support and personnel, as well as limited local high-quality evidence.

Parent–child mediation programs are intended to resolve or manage disputes and improve family functioning, but rigorous evaluations of their effectiveness are lacking. Families referred to a community-based mediation program (N = 111) were randomized to an intervention or wait-list control group, and completed three surveys over a 12-week period. With the exception of parent–reported child delinquency (which decreased more in the intervention group), this evaluation provides little support for the short-term effectiveness of parent–child mediation for improving family functioning and reducing child problem behaviors in general. Given that this is the first randomized controlled trial of a parent–child mediation program, additional evaluations involving larger samples and longer follow-ups are needed before firm conclusions can be drawn about the effectiveness of this intervention.
