Abstract

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.

摘要

背景

本研究考察了(1)抑郁症状量表(DSS)的因素结构,(2)DSS 的性别和纵向不变性,以及(3)青少年时期 DSS 量表在预测成年早期抑郁和焦虑症状方面的预测效度。

方法

数据来自正在进行的青少年尼古丁依赖研究(NDIT),这是一项对 1293 名青少年的前瞻性队列研究。

结果

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只有最小的缺失数据。验证性因子分析表明,具有躯体、抑郁和焦虑因子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,第 3 次 DSS 评分与第 4 次测量的抑郁和焦虑症状显著相关。

结论

研究结果表明,DSS 是多维的,它是一个合适的工具,可以检查青少年躯体、抑郁和焦虑症状的性别差异,以及这些症状随时间的变化。此外,它可以用于识别成年早期有精神病理学风险的个体。
