This research examined the development of anxiety across adolescence and early adulthood among a sample of juvenile offenders comprising males and females. In addition, despite the understanding of maternal substance abuse and maternal unemployment as risk factors predicting development of anxiety, this research examined the interaction between these two characteristics for doing so. Analyses used group-based trajectory modelling to provide descriptive representation of general developmental patterns of anxiety. Next, a series of multinomial logistic regression models were estimated to examine the effects of baseline covariates on the relative risk of assignment to the elucidated trajectory groups. A three-group model best fit the data, comprising low, moderate, and high anxiety trajectory groups. Results from the regression models indicate that the interaction between maternal unemployment and maternal substance abuse history significantly increased the risk of assignment to the high anxiety group.

青少年犯罪者的焦虑症状学发展：母体药物滥用和失业的作用。

这项研究调查了包括男性和女性在内的青少年犯罪者中青春期和成年早期焦虑的发展。此外，尽管了解母体药物滥用和母体失业是预测焦虑症发展的危险因素，但本研究还是考察了这两种特征之间的相互作用。分析使用基于组的轨迹模型来提供焦虑的一般发展模式的描述性表示。接下来，估计了一系列多项式逻辑回归模型，以检查基线协变量对阐明轨迹组的相对风险的影响。三组模型最适合数据，包括低，中和高焦虑轨迹组。
