The latent structure and stability of 10 common mental disorders were examined in a birth cohort at ages 18 and 21. A 2-factor model, in which some disorders were presumed to reflect internalizing problems and others were presumed to reflect externalizing problems, provided a more optimal fit to the data than either a 1- or a 4-factor model. To a significant extent, persons in the sample retained their relative positions on the latent factors across the 3-year period from age 18 to age 21. Results offer potential clarification of the meaning of comorbidity in psychopathology research by suggesting that comorbidity may results from common mental disorders being reliable, covariant indicators of stable, underlying "core psychopathological processes."
在一个出生队列中，对10种常见精神障碍的潜在结构和稳定性在18岁和21岁时进行了检查。一个双因素模型，其中一些障碍被假定反映内化问题，另一些被假定反映外化问题，比单因素或四因素模型更能优化地拟合数据。在很大程度上，样本中的个体在从18岁到21岁的三年时间里，在潜在因素上保持了他们的相对位置。结果表明，共病可能是由于常见精神障碍是稳定的潜在“核心心理病理过程”的可靠、协变指标，这为精神病理学研究中共病的意义提供了潜在的澄清。
