Moreover, the research itself suffers from fragmentation — scientists involved tend to work inside some key disciplines, such as psychiatry, paediatrics, psychology and epidemiology, and the links between research and health-care services are often poor.

此外，研究本身存在碎片化问题——参与的科学家往往在一些关键学科内工作，例如精神病学、儿科学、心理学和流行病学，而且研究和医疗保健服务之间的联系往往很差。
