摘要
目的评价简化版痤疮特异性生活质量调查问卷(Acne-Qol-19)在四川地区汉族人群中的信度和效度。方法对264例痤疮患者进行Acne-Qol-19问卷调查,采用内部一致性分析、分半信度、内容效度、准则效度及因子分析来评估Acne-Qol-19的信度和效度。结果 Acne-Qol-19量表的克朗巴赫系数(Cronbach’sα)为0.953,斯皮尔曼(Spearman-Brown)分半信度为0.902;经专家评定,量表的内容效度较好;Acne-Qol-19与Cardiff痤疮伤残指数(CADI)之间的相关系数为-0.745,P<0.001;对量表进行验证性因子分析,运用固定负荷法计算因子的标准化负荷,在自我感知维度的负荷值为0.853~0.944,社会功能维度的负荷值为0.865~0.945,情感功能维度的负荷值为0.383~0.898,痤疮症状维度的负荷值为0.612~0.867,P均<0.01。结论 Acne-Qo-19量表具有良好的信度和效度,可作为我国四川地区汉族人群痤疮患者生活质量评价的专用量表。
Objective To assess the reliability and validity of a simplified version of acne-specific quality of life （Acne-Qol-19） instrument in Han populations in Sichuan province. Methods Acne-Qol-19 was administered to 264 acne patients. Internal consistency, split-half reliability, content validity, criterion validity and construct validity （factor analysis） of Acne-Qol-19 were assessed. Results The Acne-Qol-19 obtained a Cronbach＇s α of 0.953 and split-half reliability of 0.902 （Spearman-Brown）. Its content validity was well confirmed by dermatologists. The Acne-Qol-19 result was strongly associated （r =－0.745） with Cardiff acne disabled index （CADI） （P 〈0.001）. Confirmatory factor analysis yielded standardized loading of 0.853-0.944 on self-perception, 0.865-0.945 on role-social dimension, 0.383-0.898 on role-emotional dimension, and 0.612-0.867 on acne symptoms （P 〈0.01）. Conclusion Acne-Qol-19 has good validity and reliability in Han populations in Sichuan.
