Preventing mental health problems in children: a population-based cluster controlled trial

全国心理健康调查（2000年）发现，每7名儿童中就有1名有外化（攻击）和内化（焦虑、抑郁）问题。早期的心理健康问题会导致后来的问题，给社会带来高昂的代价，包括临床、补救教育和刑事司法服务。因此，早期预防对国民福祉和生产力至关重要。迄今为止，为数不多的预防性儿童早期项目的效果有限，而且并不真正以人口为基础。拟议的养育/家庭支助试验旨在通过比较和计算可在整个社区内实施的两种方法来克服这些障碍。这项试验将有助于阐明预防生命早期心理健康问题的最佳初级保健。

The National Mental Health Survey (2000) found 1 in 7 children have externalising (aggression) and internalising (anxiety, depression) problems. Early mental health problems beget later problems with high costs to society, including clinical, remedial education and criminal justice services. Hence, early prevention is vital for national well-being and productivity. The few preventive early childhood programs to date are limited in effectiveness and not truly population-based. The proposed parenting / family support trial aims to overcome these obstacles, by comparing and costing two approaches that can be implemented within whole communities. The trial will help clarify optimal primary care to prevent mental health problems early in life.
