This study aimed at proposing and testing a conceptual model of youth suicide attempt. We proposed a model that began with family factors such as a history of physical abuse and parental divorce/separation. Family relationship, presence of psychopathology, life stressors, and suicide ideation were postulated as mediators, leading to youth suicide attempt. The stepwise entry of the risk factors to a logistic regression model defined their proximity as related to suicide attempt. Path analysis further refined our proposed model of youth suicide attempt. Our originally proposed model was largely confirmed. The main revision was dropping parental divorce/separation as a risk factor in the model due to lack of significant contribution when examined alongside with other risk factors. This model was cross-validated by gender. This study moved research on youth suicide from identification of individual risk factors to model building, integrating separate findings of the past studies.
本研究旨在提出并检验一个青年自杀企图的概念模型。我们提出了一个模型，该模型从家庭因素开始，如身体虐待史和父母离婚/分居。家庭关系、精神病理学的存在、生活压力源和自杀意念被假设为中介因素，导致青年自杀企图。风险因素逐步进入逻辑回归模型，定义了它们与自杀企图的关系。路径分析进一步完善了我们提出的青年自杀企图模型。我们最初提出的模型得到了很大程度的证实。主要修订是由于与其他风险因素一起检查时，父母离婚/分居作为风险因素的贡献不显著，因此将其从模型中删除。该模型通过性别进行了交叉验证。本研究将青年自杀研究从个体风险因素的识别推进到模型构建，整合了过去研究的独立发现。
