title: [Authorization, translation, back translation and language modification of the simplified Chinese adult comorbidity-27 index].
abstract: Objective:To translate the adult comorbidity evaluation-27(ACE-27) index authored by professor JF Piccirillo into Chinese and for the purpose of assessing the possible impact of comorbidity on survival of oral cancer patients and improving cancer staging.Methods:The translation included the following steps, obtaining permission from professor Piccirillo, translation, back translation, language modification, adjusted by the advice from the professors of oral and maxillofacial surgery. The test population included 154 patients who were admitted to Peking University of Stomatology during March 2011. Questionnaire survey was conducted on these patients. Retest of reliability, internal consistency reliability, content validity, and structure validity were performed.Results:The simplified Chinese ACE-27 index was established. The Cronbach's α was 0.821 in the internal consistency reliability test. The Kaiser-Meyer-Olkin (KMO) value of 8 items was 0.859 in the structure validity test.Conclusions:The simplified Chinese ACE-27 index has good feasibility and reliability. It is useful to assess the comorbidity of oral cancer patients.
