Trajectories between childhood internalising behaviour problems and adolescent depressive symptoms

众所周知，抑郁症状会在青少年时期急剧升级。经历过一次抑郁的青少年很可能在成年后进一步患上精神疾病。通过研究描述抑郁症状早期出现的相关因素和过程，可能会促进预防抑郁症的努力。为了促进这种理解，该项目将分析部分通过NHMRC对澳大利亚气质项目（ATP）研究人员的支持收集的数据。ATP数据将用于检查与儿童期到青春期抑郁症状发展和进展相关的因素。ATP数据集包括从多个来源（父母、教师和青年）收集的关于儿童和青少年气质、行为问题、母子关系、健康、抑郁症状、学业成绩、学校适应、社交技能、同伴关系、养育做法、压力生活事件和社会人口因素的详细纵向数据。在1983年纳入队列的2443名原始样本（年龄4-8个月）中，应在2000年完成1350名青少年的子样本（年龄17-18岁）的数据收集。通过对本应用中提出的ATP数据的分析，将开发模型来解释儿童和青少年早期的风险和弹性过程影响青少年抑郁症的发展和过程，针对不同的青少年亚群。为了实现这一目标，分析将：确定从童年内化行为问题到青少年抑郁症状的不同轨迹的群体；2. 比较各组，以确定导致从内化行为问题发展为抑郁症状的因素，同时也确定似乎阻碍这种发展的因素；3. 比较各组以确定与青春期短暂性和持续性抑郁症状相关的因素。

Depressive symptoms are known to escalate sharply through the adolescent years. Adolescents who experience an episode of depression are very likely to experience further mental illness as adults. Efforts to prevent depressive illness may be advanced by research delineating the factors and processes implicated in the early emergence of depressive symptoms. To advance such an understanding this project will analyse data collected, in part, through NHMRC support to Australian Temperament Project (ATP) researchers. The ATP data will be used to examine factors associated with the development and progression of depressive symptoms from childhood to adolescence. The ATP data set includes detailed longitudinal data collected from multiple sources (parents, teachers and youth) concerning child and adolescent temperament, behavioural problems, mother-child relations, health, depressive symptoms, school achievement, school adjustment, social skills, peer relationships, parenting practices, stressful life events, and sociodemographic factors. Of an original sample of 2443 enrolled in the cohort in 1983 (aged 4-8 months) a subsample of 1,350 adolescents should complete the data collection due in 2000 (age 17-18). Through the analysis of ATP data proposed in this application, models will be developed to explain the risk and resiliency processes in childhood and early adolescence influencing the development and course of adolescent depression, for different subgroups of adolescents. To achieve this objective, analyses will: 1. identify groups who have differing trajectories from childhood internalising behaviour problems to adolescent depressive symptoms; 2. compare groups to identify factors that contribute to the progression from internalising behaviour problems to depressive symptoms, while also identifying factors which appear to impede such progression and; 3. compare groups to identify factors associated with transient versus persistent depressive symptoms in adolescence.
