目的皮肤病家庭生活质量指数（Family Dermatology Life Quality Index， FDLQI）是一种评估皮肤病患者家庭成员生活质量的工具。本研究的目的是描述该问卷的文化适应性，并评估波斯语版本的心理测量特性。首先将问卷翻译成波斯语，然后进行反翻译。整个循环不断重复，直到对最佳翻译达成共识。下一步，进行认知汇报，在FDLQI开发人员批准波斯语版本后，将其分发给100名皮肤病患者的家庭成员，以评估其效度和信度。参与者的平均年龄为37.1岁（±12.3岁）。FDLQI平均评分15.4（+/- 5.5）分，最高评分30分，最低评分6分。研究对象的生活品质在年龄、性别、教育程度及家庭关系上无显著差异。Cronbach’s alpha为0.87。探索性因素分析显示，单因素解决方案占40.7%的方差。验证性因子分析支持单维模型。本研究结果显示波斯语版FDLQI具有可接受的因子效度和内部一致性信度。
Purpose Family Dermatology Life Quality Index (FDLQI) is an instrument for assessing the quality of life of family members of dermatologic patients. The aim of this study was to describe the cultural adaptation of this questionnaire and to assess psychometric properties of the Persian version.At first, the questionnaire was translated into Persian, and then back-translation was performed. The whole cycle was repeated until a consensus was reached about the optimal translation. In the next step, cognitive debriefing was performed, and after approval of the Persian version by FDLQI developers, it was distributed among 100 family members of dermatological patients in order to evaluate its validity and reliability.Mean age of participants was 37.1 years (+/- 12.3). Mean score of FDLQI was 15.4 (+/- 5.5) with maximum and minimum scores of 30 and 6, respectively. The quality of life of studied participants showed no significant difference based on age-group, sex, educational level and the family relationship. Cronbach's alpha was calculated as 0.87. Exploratory factor analysis revealed a one-factor solution that accounted for 40.7 % of the variance. The unidimensional model was supported by confirmatory factor analysis.The results of the present study showed that the Persian version of FDLQI has acceptable factorial validity and internal consistency reliability.
