特质-状态-时机（TSO）协方差模型代表了研究潜在结构纵向稳定性方法的重要进展。这些模型只在相当有限的条件下进行了研究（例如，每个波只有2个τ-等效指示器）。在这项研究中，蒙特卡罗模拟揭示了每波有2个与3个指标的影响，并放宽了波内tau等效性。这些修改进行了检查的条件下，不同的波内性状方差和跨波稳定性的场合影响。总的来说，TSO模型表现良好（即，在大多数这些条件下，收敛问题或超出范围的参数估计）;然而，当每波只使用2个指标时，当因子载荷很小时，当性状方差的比例很高或很低时，以及当场合因子高度稳定时，不适当的解决方案的可能性增加。基于这些发现，建议成功地使用TSO模型与真实的数据。
Trait-State-Occasion (TSO) covariance models represent an important advance in methods for studying the longitudinal stability of latent constructs. Such models have only been examined under fairly restricted conditions (e.g., having only 2 tau-equivalent indicators per wave). In this study, Monte Carlo simulations revealed the effects of having 2 versus 3 indicators per wave and relaxing the within-wave tau equivalence. These modifications were examined under conditions that varied with regard to the within-wave trait variance and the cross-wave stability of occasion influences. In general, the TSO model performed well (i.e., few convergence problems or out-of-range parameter estimates) under most of these conditions; however, the likelihood of improper solutions increased when only 2 indicators were used per wave, when factor loadings were small, when the proportion of trait variance was either very high or very low, and when the occasion factor was highly stable. Based on these findings, recommendations are made for successful use of TSO models with real data.
