背景资料：本研究探讨了（1）抑郁症状量表（DSS）的因子结构，（2）DSS的性别和纵向不变性，（3）青少年期DSS量表在预测成年早期抑郁和焦虑症状方面的预测效度。数据来自青少年尼古丁依赖（NDIT）研究，这是一项正在进行的前瞻性队列研究，共有1，293名青少年参与。分析样本包括527名参与者，他们在随访期间提供了完整的数据或最少的缺失数据。验证性因素分析显示，具有躯体、抑郁和焦虑因素的相互关联的三因素模型提供了最佳拟合。此外，该模型在性别和时间上是不变的。最后，DSS分数在时间3与抑郁和焦虑症状在时间4测量显着相关。结论：结果表明，DSS是多维的，它是一个合适的工具来检查性别差异的躯体，抑郁和焦虑症状，以及这些症状随着时间的推移在青少年中的变化。此外，它还可用于识别成年早期有精神病理学风险的个体。
Background: This study examined (1) the factor structure of a depressive symptoms scale (DSS), (2) the sex and longitudinal invariance of the DSS, and (3) the predictive validity of the DSS scale during adolescence in terms of predicting depression and anxiety symptoms in early adulthood.Methods: Data were drawn from the Nicotine Dependence in Teens (NDIT) study, an ongoing prospective cohort study of 1,293 adolescents.Results: The analytical sample included 527 participants who provided complete data or had minimal missing data over follow-up. Confirmatory factor analysis revealed that an intercorrelated three-factor model with somatic, depressive, and anxiety factors provided the best fit. Further, this model was invariant across sex and time. Finally, DSS scores at Time 3 correlated significantly with depressive and anxiety symptoms measured at Time 4.Conclusions: Results suggest that the DSS is multidimensional and that it is a suitable instrument to examine sex differences in somatic, depressive, and anxiety symptoms, as well as changes in these symptoms over time in adolescents. In addition, it could be used to identify individuals at-risk of psychopathology during early adulthood.
