过去对抑郁症状的潜在结构的研究产生了混合的结果，一些研究支持连续的概念化，另一些研究支持分类。然而，没有一项研究专门针对老年人样本来研究这个研究问题，尽管晚年抑郁症状具有潜在的独特性。在本研究中，在跨越20年的三波数据收集中，对1289名个体的晚年抑郁症状的潜在结构进行了研究。使用来自研究诊断标准的抑郁症指标采用分类方法。最大特征值（MAXEIG）分析和尺蠖一致性检验一般支持一个明确的概念化，并确定了一组主要特征是死亡/自杀的想法。然而，与分类抑郁变量相比，持续治疗的抑郁症状通常是相关标准变量的更好预测因子。这些发现表明，死亡和自杀的想法可能是一种特定类型的晚年抑郁症的特征，但持续的概念化仍然通常最大限度地提高了晚年抑郁症状的预测效用。
Past studies of the underlying structure of depressive symptoms have yielded mixed results, with some studies supporting a continuous conceptualization and others supporting a categorical one. However, no study has examined this research question with an exclusively older adult sample, despite the potential uniqueness of late-life depressive symptoms. In the present study, the underlying structure of late-life depressive symptoms was examined among a sample of 1289 individuals across three waves of data collection spanning 20 years. A taxometric methodology was employed using indicators of depression derived from the Research Diagnostic Criteria. Maximum eigenvalue (MAXEIG) analyses and inchworm consistency tests generally supported a categorical conceptualization and identified a group that was primarily characterized by thoughts about death/suicide. However, compared to a categorical depression variable, depressive symptoms treated continuously were generally better predictors of relevant criterion variables. These findings suggest that thoughts of death and suicide may characterize a specific type of late-life depression, yet a continuous conceptualization still typically maximizes the predictive utility of late-life depressive symptoms.
