What is Re: Patient-based outcomes of cervical dystonia: A review of rating scales about?

We read with interest the review of Cano and colleagues 1 on rating scales for cervical dystonia (CD). The authors performed a computerized database search (from 1966 to 2002) on rating scales for CD in the English language, and state that none of the 10 identified CD-specific rating scales satisfy the recommended criteria for health measurement rating scales defined by the Scientific Advisory Group of the Medical Outcomes Trust (SAC). 2 They also include the Craniocervical Dystonia Questionnaire (CDQ-24), which was developed and validated recently. 3 Because our study on the development and validation of the CDQ-24 was not published as a full-length original paper and only was available in abstract form 4 at the time when Cano and associates submitted their review, key aspects of our scale are not appreciated. In fact, our study clearly shows that the CDQ-24 fulfills the essential criteria for health measurement rating scales defined by the SAC, including reliability, validity, and responsiveness to therapy. 3 Regarding reliability, both measures used showed satisfactory values across all subscales of the CDQ-24 (internal consistency, ␣ ϭ 0.77-0.89; testretest reliability, ICC Ͼ 0
