研究人员一直致力于澄清情绪障碍之间的结构关系，以努力改进诊断分类。然而，焦虑和情绪障碍的高度并存导致研究人员在《精神疾病诊断和统计手册》(DSM-IV，APA 2000)中将焦虑和抑郁的当前结构描绘为更多的描述性而不是经验性的。这项研究在一个患有情绪障碍的青少年的临床样本中评估了各种结构模型。测试了三个先验因素模型，其中最符合数据的模型表明，焦虑和情绪障碍的维度将在一个更高级别的因素内进行分层组织。这支持了流行的观点，即焦虑和情绪障碍在儿童中并存的部分原因是共同的脆弱性(例如，消极情感)。与其他疾病相比，抑郁症和广泛性焦虑对高阶因子的影响更大，这可能是两者之间共患率特别高的原因之一。对儿童和青少年的情绪和焦虑症的分类和治疗的意义进行了讨论。
Investigators are persistently aiming to clarify structural relationships among the emotional disorders in efforts to improve diagnostic classification. The high co-occurrence of anxiety and mood disorders, however, has led investigators to portray the current structure of anxiety and depression in theDiagnostic and Statistical Manual of Mental Disorders(DSM-IV,APA 2000) as more descriptive than empirical. This study assesses various structural models in a clinical sample of youths with emotional disorders. Three a priori factor models were tested, and the model that provided the best fit to the data showed the dimensions of anxiety and mood disorders to be hierarchically organized within a single, higher-order factor. This supports the prevailing view that the co-occurrence of anxiety and mood disorders in children is in part due to a common vulnerability (e.g., negative affectivity). Depression and generalized anxiety loaded more highly onto the higher-order factor than the other disorders, a possible explanation for the particularly high rates of comorbidity between the two. Implications for the taxonomy and treatment of mood and anxiety disorders for children and adolescents are discussed.
