The New South Wales Child Development Study (NSW-CDS) was established to enable a life course epidemiological approach to identifying risk and protective factors for childhood and adolescent-onset mental health problems, and other adverse outcomes (e.g. educational underachievement, welfare dependence, criminality). The study methodology entails repeated waves of record linkage for a population of Australian children in the state of NSW, funded by competitive funding awards (see Funding), and conducted in partnership with multiple NSW government departments. Table 1 summarizes the study phases (waves of record linkage) and measurements.

Longitudinal study phases and measurements

Study phase	Measurements
Wave 1 (Record linkage up to child’s age 5–6 years)	Linked records spanning 1994–2009
	Australian Early Development Census
	Administrative government data from health, child protection, justice and education departments
Wave 2 (Record linkage up to child’s age 12–14 years)	Linked records spanning 1994–2016:
	Australian Early Development Census
	Administrative government data from health, child protection, justice and education departments.
	The Middle Childhood Survey (conducted in 2015) and the Survey of School Promotion of Emotional and Social Health (SSPESH)
Ongoing	Subsequent record linkages are planned to occur until the child cohort reaches at least 25 years, and will include Commonwealth data collections (e.g. Medicare Benefits Schedule and Pharmaceutical Benefits Scheme, Department of Social Services)

队列资料：新南威尔士州儿童发展研究（NSW-CDS）-Wave 2（儿童年龄13岁）

建立新南威尔士州儿童发展研究（NSW-CDS）的目的是要采用一种生命周期流行病学方法来确定儿童和青少年期心理健康问题以及其他不良后果（例如教育水平，成就依赖，犯罪行为）的风险和保护因素）。该研究方法需要在新南威尔士州的澳大利亚儿童中屡屡创纪录地建立联系，这是由竞争性资金奖励（请参阅“资助”）提供资金，并与新南威尔士州多个政府部门合作进行的。表1总结了研究阶段（记录链接的波）和测量。

纵向研究阶段和测量

学习阶段	测量
第一波（记录链接直到5-6岁的孩子）	1994年至2009年的链接记录
	澳大利亚早期发展普查
	卫生，儿童保护，司法和教育部门的政府行政数据
第二波（记录与儿童12-14岁之间的联系）	1994年至2016年的关联记录：
	澳大利亚早期发展普查
	来自卫生，儿童保护，司法和教育部门的政府行政数据。
	中期儿童调查（2015年进行）和学校促进情绪和社会健康调查（SSPESH）
进行中	计划在儿童队列达到至少25岁之前进行后续记录关联，并将包括英联邦数据收集（例如，社会服务部的Medicare福利计划和Pharmaceutical Benefits Scheme）
