大多数关于精神病理学协方差结构的实证研究都局限于成人。由于疾病的含义、发病年龄、持续性和表现在整个生命周期中有所不同，因此这项工作没有发育方面的信息。本研究探讨青少年精神病理的潜在结构，以及精神病理维度与药物滥用和精神健康问题的性别和人格风险概况之间的关系。方法对2175名13.3岁青少年的资料进行分析。采用验证性因子分析对五维模型进行检验，采用多指标多因模型对外部效度进行检验。结果由内化、外化、思维障碍3个相关因素和1个一般心理病理因素组成的修正双因素模型拟合效果最佳。女性的平均内化水平较高，男性的平均外化水平较高。在思维障碍倾向和一般精神病理方面没有明显的性别差异。内在化、外在化、思维障碍和一般精神病理倾向的特征是人格特征的许多差异。结论本研究首次确定了包含特定思维障碍因素的双因素模型。研究结果强调了跨诊断治疗方法的实用性和以经验为基础的方式重组精神病理学的重要性。
Background Most empirical studies into the covariance structure of psychopathology have been confined to adults. This work is not developmentally informed as the meaning, age-of-onset, persistence and expression of disorders differ across the lifespan. This study investigates the underlying structure of adolescent psychopathology and associations between the psychopathological dimensions and sex and personality risk profiles for substance misuse and mental health problems.Method This study analyzed data from 2175 adolescents aged 13.3 years. Five dimensional models were tested using confirmatory factor analysis and the external validity was examined using a multiple-indicators multiple-causes model.Results A modified bifactor model, with three correlated specific factors (internalizing, externalizing, thought disorder) and one general psychopathology factor, provided the best fit to the data. Females reported higher mean levels of internalizing, and males reported higher mean levels of externalizing. No significant sex differences emerged in liability to thought disorder or general psychopathology. Liability to internalizing, externalizing, thought disorder and general psychopathology was characterized by a number of differences in personality profiles.Conclusions This study is the first to identify a bifactor model including a specific thought disorder factor. The findings highlight the utility of transdiagnostic treatment approaches and the importance of restructuring psychopathology in an empirically based manner.
