Abstract

OBJECTIVES

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 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 ( =#-0.745) with Cardiff acne disabled index (CADI) ( <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 ( <0.01).

CONCLUSION

Acne-Qol-19 has good validity and reliability in Han populations in Sichuan.

摘要

目的

评估简化版痤疮特异性生活质量（Acne-Qol-19）量表在四川省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量表测评。评估Acne-Qol-19的内部一致性、分半信度、内容效度、效标效度和结构效度（因子分析）。

结果

Acne-Qol-19的Cronbach's α系数为0.953，分半信度为0.902（Spearman-Brown校正）。皮肤科医生充分证实了其内容效度。Acne-Qol-19结果与卡迪夫痤疮残疾指数（CADI）密切相关（r = -0.745）（P < 0.001）。验证性因子分析得出，自我认知维度的标准化载荷为0.853 - 0.944，角色-社会维度为0.865 - 0.945，角色-情感维度为0.383 - 0.898，痤疮症状维度为0.612 - 0.867（P < 0.01）。
