本研究利用潜在特质-状态模式估计青少年抑郁情绪的稳定成分和变化成分。在4次测量时（间隔6个月）分别评估了男性和女性CES-D的析因结构。同时估计了CES-D得分的一般性状、状态、特定性状和随机误差参数的方差分解，并进行了统计检验。参数估计表明，CES-D测量的特质和状态抑郁症同样好，和特质特异性方差参数是统计学上显着的，但大大小于那些与一般的特质和状态抑郁症。研究结果进行了讨论，关于青少年的抑郁情绪波动和潜在的有用性的潜在特质状态模型来捕捉这种动态的发展特征。
This study utilized the latent trait-state model for estimating stable and changing components of depressive symptomology in adolescents. The factorial structure of the CES-D was assessed separately for males and females at four measurement occasions, at six-month intervals. The variance decomposition of general trait, state, specific trait, and random error parameters for the CES-D scores was estimated simultaneously and tested statistically. Parameter estimates indicated that the CES-D measured both trait- and state-depression about equally well, and that the trait-specific variance parameter was statistically significant, but substantially smaller than those associated with general trait- and state-depression. Findings are discussed with regard to depressive mood fluctuations among adolescents and the potential usefulness of the latent trait-state model to capture such dynamic features of development.
