Patients with chronic wounds experience various biopsychosocial problems which severely affects their quality of life (QoL). Thus, a Persian instrument to assess the QoL of these patients is required. This study aimed to determine the psychometric properties of the Persian version of the wound-QOL questionnaire.
This methodological study was performed on Iranian patients during 2021-2022. The translation was carried out forward-backward method. Face validity was addressed with 10 patients and content validity with 12 wound specialists. Construct validity was also assessed by performing exploratory factor analysis (EFA) ( = 100) and convergent validation with EQ-5D-3L plus Pain VAS Score and known-groups validity. The reliability was assessed by internal consistency using Cronbach's alpha coefficient and test-retest.
A total of 100 patients with chronic wounds were included in the study. Two factors with cumulative variance of 65.39% were extracted during EFA. The results revealed a significant and high correlation between the total scores of wound-QOL questionnaire, the Persian version of EQ-5D-3L ( = 0.000, = 0.502), and Pain score (0-10; = 0.000, = 0.627). The Cronbach's alpha was 0.743 and stability of the questionnaire ( = 0.872) was confirmed. In confirming the known-groups validity, the results showed that this tool can differentiate the QOL of patients with different wounds.
The Persian version of the wound-QOL questionnaire is a valid and reliable questionnaire which can measure the QoL of patients with chronic wounds. This instrument can be used in clinical evaluation as well as research purposes across the Iranian population.
慢性伤口患者会经历各种生物心理社会问题，这严重影响他们的生活质量（QoL）。因此，需要一种波斯语工具来评估这些患者的生活质量。本研究旨在确定伤口QOL问卷波斯语版本的心理测量特性。
本方法学研究于2021年至2022年对伊朗患者进行。采用正向-反向翻译法。通过10名患者评估表面效度，12名伤口专家评估内容效度。还通过进行探索性因子分析（EFA）（n = 100）、与EQ-5D-3L加疼痛视觉模拟评分进行收敛效度验证以及已知群体效度来评估结构效度。通过使用Cronbach's alpha系数进行内部一致性和重测来评估信度。
本研究共纳入100例慢性伤口患者。在EFA过程中提取了两个累积方差为65.39%的因子。结果显示，伤口QOL问卷总分与波斯语版本的EQ-5D-3L（r = 0.000，p = 0.502）和疼痛评分（0 - 10；r = 0.000，p = 0.627）之间存在显著且高度的相关性。Cronbach's alpha为0.743，问卷的稳定性（r = 0.872）得到证实。在确认已知群体效度时，结果表明该工具可以区分不同伤口患者的生活质量。
伤口QOL问卷波斯语版本是一种有效且可靠的问卷，可用于测量慢性伤口患者的生活质量。该工具可用于伊朗人群的临床评估以及研究目的。
