The present study examined the structural relationships among anxiety and depressive symptoms in a sample of high school juniors. The best-fitting structural representation was a tri-level hierarchical arrangement with a broad general factor (general distress), two factors of intermediate breadth (anxious-misery and fears), and five conceptually meaningful, narrow group factors. In accord with the integrative hierarchical model of anxiety and depression, the results supported a structure with a symptom factor central to major depression, and other symptom factors specific to particular anxiety disorders. These group factors displayed significant, unique associations with clinician severity ratings (CSRs) for their respective DSM diagnoses. The hierarchical arrangement demonstrated temporal invariance over a one-year period and configural and partial metric invariance in females and males. Implications for DSM classification and arrangement of anxiety and depressive disorders are discussed as is how present findings help bridge existing research conducted at symptom and diagnostic levels.
本研究考察了高中生样本中焦虑和抑郁症状之间的结构关系。最佳的结构表示是一个三层层次结构，具有一个广泛的一般因素（一般困扰）、两个中等广度的因素（焦虑痛苦和恐惧）和五个概念上有意义的、狭窄的组因素。与焦虑和抑郁的综合层次模型一致，结果支持了一种以主要抑郁症核心症状因素为中心的结构，以及特定于特定焦虑障碍的其他症状因素。这些组因素与各自 DSM 诊断的临床严重程度评定（CSR）有显著的、独特的关联。层次结构在一年的时间内表现出时间不变性，在女性和男性中具有组态和部分度量不变性。讨论了 DSM 分类和焦虑和抑郁障碍的排列方式，以及目前的发现如何有助于弥合在症状和诊断水平上进行的现有研究之间的差距。
