潜在增长模型下抑郁症状变化轨迹的研究进展

潜在增长模型已成为国外纵向研究的有力分析工具。通过对国外抑郁症状纵向研究及潜在增长模型应用研究的整理，发现患者抑郁症状的变化轨迹存在个体差异，但其中又存在相似特征，根据这些特征可以将抑郁症状的变化轨迹主要分为四种，早期症状快速减少、治疗期间症状缓慢平稳减少、早期症状减少后期出现反弹和症状未出现明显变化。通过总结该模型在抑郁症状研究领域的应用成果，了解抑郁症患者抑郁症状变化的情况，以期为我国相关研究的进一步开展提供新思路。

Research Progress on Trajectories of Depressive Symptom Changes under Latent Growth Model

Latent growth models (LGM) have emerged as a powerful analytical tool in longitudinal research abroad. Through a review of foreign longitudinal studies on depressive symptoms and the application of LGM, this study identified individual differences in the trajectories of depressive symptoms among patients. However, common characteristics were also found, allowing the categorization of depressive symptom trajectories into four main types: rapid early symptom reduction, slow and steady symptom reduction during treatment, rebound after an initial symptom reduction, and no significant change in symptoms. By summarizing the application of this model in the field of depressive symptom research, a deeper understanding of the trajectory of depressive symptoms in patients with depression was obtained. This knowledge aims to provide new insights for further research in related fields in China.
