This study aimed to assess the psychometric properties of the Persian version of the Ferrans and Powers 3.0 quality of life index (dialysis type) in patients receiving hemodialysis (HD) in order to describe their health-related quality of life (HRQOL).
The sample (n = 150) consisted of adult HD patients receiving HD for at least 6 months from the establishment of the study. A total of 88 men and 62 women, with an average age of 50.47, from Shiraz, southern Iran, were enrolled in this study. The questionnaire was translated into Persian language using back translation and bilingual techniques. Convergent, discriminant, and construct validity of the Ferrans and Powers 3.0 dialysis version was evaluated. To check the internal consistency of the data, Cronbach's alpha, which indicates the reliability of the data, was used for the entire questionnaire and for the subscales.
The convergent and discriminant validity and success scaling rate for both sexes were 100 %. Cronbach's alpha was 0.95 overall, which was greater than 0.7 for all the subscales except for the family subscale. Our results suggest that HD patients in southern Iran have higher HRQOL scores when compared with those in other countries. Despite the higher mean HRQOL score for men compared with women, men had significantly higher HRQOL scores only in the health and functioning subscale. There was no significant correlation between HD patients' HRQOL and educational level.
The Persian version of Ferrans and Powers 3.0 has sufficient reliability and validity for measuring the quality of life of Persian-speaking HD patients. Female HD patients need more support and attention from family and society.
本研究旨在评估接受血液透析（HD）的患者中波斯语版费兰斯和鲍尔斯3.0生活质量指数（透析类型）的心理测量特性，以描述他们的健康相关生活质量（HRQOL）。
样本（n = 150）由自研究开始起接受HD至少6个月的成年HD患者组成。本研究纳入了来自伊朗南部设拉子的88名男性和62名女性，平均年龄为50.47岁。问卷通过回译和双语技术翻译成波斯语。评估了费兰斯和鲍尔斯3.0透析版的收敛效度、区分效度和结构效度。为检查数据的内部一致性，对整个问卷及其子量表使用了表示数据可靠性的克朗巴哈α系数。
男女的收敛效度、区分效度和成功缩放率均为100%。总体克朗巴哈α系数为0.95，除家庭子量表外，所有子量表的该系数均大于0.7。我们的结果表明，与其他国家的患者相比，伊朗南部的HD患者HRQOL得分更高。尽管男性的平均HRQOL得分高于女性，但男性仅在健康和功能子量表中HRQOL得分显著更高。HD患者的HRQOL与教育水平之间无显著相关性。
波斯语版费兰斯和鲍尔斯3.0在测量说波斯语的HD患者生活质量方面具有足够的可靠性和有效性。女性HD患者需要家庭和社会给予更多支持和关注。
