抽动障碍是异质性的，患者内部和患者之间的症状差异很大。探索症状群可能有助于识别经验和治疗进口的症状维度。本文介绍了两项研究的结果调查抽动症状集群使用的样本99青年（M年龄= 10.7，81%男性，77%白人）诊断为原发性抽动障碍（抽动秽语综合征或慢性抽动障碍），在两个大学为基础的门诊专科抽动及相关疾病。在研究1中，耶鲁大学全球抽搐严重程度量表（YGTSS）的聚类分析确定了四个症状维度：主要是复杂抽搐;简单的头/脸抽搐;简单的身体抽搐;和简单的声音/面部抽搐。在研究2中，这些聚类显示与人口统计学和临床特征差异相关。研究结果支持先前的研究抽动现象，有助于组织治疗目标，并建议抽动障碍的症状维度作进一步评估。
Tic disorders are heterogeneous, with symptoms varying widely both within and across patients. Exploration of symptom clusters may aid in the identification of symptom dimensions of empirical and treatment import. This article presents the results of two studies investigating tic symptom clusters using a sample of 99 youth (M age = 10.7, 81% male, 77% Caucasian) diagnosed with a primary tic disorder (Tourette’s disorder or chronic tic disorder), across two university-based outpatient clinics specializing in tic and related disorders. In Study 1, a cluster analysis of the Yale Global Tic Severity Scale (YGTSS) identified four symptom dimensions: predominantly complex tics; simple head/face tics; simple body tics; and simple vocal/facial tics. In Study 2, these clusters were shown to be differentially associated with demographic and clinical characteristics. Findings lend support to prior research on tic phenomenology, help to organize treatment goals, and suggest symptom dimensions of tic disorders for further evaluation.
