目的：探讨颈性肌张力障碍综合评定量表的临床应用价值。这是一个模块量表，对多伦多西部痉挛性斜颈评定量表（由评估运动严重程度、残疾和疼痛的三个分量表组成）进行了修改，现称为修订的多伦多西部痉挛性斜颈量表-2。一个新开发的精神病筛查工具;和颈部肌张力障碍影响概况-58作为生活质量的措施。十名肌张力障碍专家使用综合量表对颈部肌张力障碍受试者进行评分。临床技术评估的可靠性，项目相关性和因素结构的规模的每个模块。共有208例颈部肌张力障碍患者（73%为女性，年龄59±10岁，病程15±12年）。运动严重程度子量表的内部一致性是可以接受的（Cronbach α = 0.57）。项目与总相关性表明，消除相关性低（<0.20）的项目将α增加到0.71。残疾和疼痛分量表的内部一致性估计值分别为0.88和0.95。精神病筛查量表的Cronbach α为0.84，项目与总相关性令人满意。将多伦多西部痉挛性斜颈量表-2的分量表与精神病筛查量表合并，Cronbach 'salpha值为0.88，结构效度评估显示有4个合理因素：运动、残疾、疼痛和精神障碍。颈椎肌张力障碍影响特征-58的α为0.98，其结构通过验证性因素分析进行了验证。颈椎肌张力障碍综合评定量表的模块内部与逻辑因素结构一致。
To test the clinimetric properties of the Comprehensive Cervical Dystonia Rating Scale. This is a modular scale with modifications of the Toronto Western Spasmodic Torticollis Rating Scale (composed of three subscales assessing motor severity, disability and pain) now referred to as the revised Toronto Western Spasmodic Torticollis Scale-2.; a newly developed psychiatric screening instrument; and the Cervical Dystonia Impact Profile-58 as a quality of life measure. Ten dystonia experts rated subjects with cervical dystonia using the comprehensive scale. Clinimetric techniques assessed each module of the scale for reliability, item correlation and factor structure. There were 208 cervical dystonia patients (73% women, age 59±10 years, duration 15±12 years). The internal consistency of the motor severity subscale was acceptable (Cronbach’s alpha = 0.57). Item to total correlations showed that elimination of items with low correlations (<0.20) increased alpha to 0.71. Internal consistency estimates for the subscales for disability and pain were 0.88 and 0.95 respectively. The psychiatric screening scale had a Cronbach’s alpha of 0.84 and satisfactory item to total correlations. When the subscales of the Toronto Western Spasmodic Torticollis scale -2 were combined with the psychiatric screening scale, Cronbach's alpha was 0.88, and construct validity assessment demonstrated four rational factors: motor, disability, pain and psychiatric disorders. The Cervical Dystonia Impact Profile-58 had an alpha of 0.98 and its construction was validated through a confirmatory factor analysis. The modules of the Comprehensive Cervical Dystonia Rating Scale are internally consistent with a logical factor structure.
