Structural psychopathology research has identified two broad factors--internalizing and externalizing--that account for comorbidity among many common mental disorders. Evaluating the utility of these factors for nosology, research, and treatment entails expanding beyond a cross-sectional understanding to how these factors evolve over time. We tested factorial invariance of internalizing in three age cohort groups--35 years and under (n = 1,729), 36-50 years (n = 2,719), and over 50 years (n = 2,601)--as well as the long-term stability of internalizing within individuals. Internalizing showed a notable degree of invariance between cohorts and within cohorts over time; long-term internalizing stability was equivalently moderate-to-high in each cohort.
结构心理病理学研究已经确定了两个广泛的因素——内化和外化——它们可以解释许多常见精神障碍之间的共病现象。为了评估这些因素在分类学、研究和治疗中的效用，需要超越横断面的理解，研究这些因素随时间的演变。我们在三个年龄队列组（35 岁及以下（n=1729）、36-50 岁（n=2719）和 50 岁以上（n=2601））中测试了内化的因子不变性，以及个体内部内化的长期稳定性。在队列之间以及随着时间的推移在队列内部，内化表现出显著的不变性；在每个队列中，长期内化的稳定性都是中等到高度。
