A limited number of headache disability indices exist that can evaluate and manage different disabilities related to headache among Iranian patients.
This study aimed to translate and validate the Persian version of the Henry Ford headache disability inventory (HDI).
The original questionnaire was translated and culturally adapted to the Persian setting. A total of 250 patients with chronic headache were enrolled in this study. The questionnaire's face validity, content validity, and convergent validity with Short-Form Health Survey (SF-36) were evaluated and a confirmatory factor analysis (CFA) was conducted. Its internal consistency was also assessed and its short- and long-term test-retest reliability were examined by intraclass correlation coefficient (ICC).
The content validity indices were 0.85, 0.99, and 0.97 for simplicity, relevance, and clarity, respectively. The content validity ratio was calculated as one for all items. The findings of CFA confirmed that this index had a good fit. Cronbach's alpha was 0.91, 0.82, and 0.86 for the entire questionnaire as well as its functional and emotional subscales, respectively. The ICC was also calculated as 0.97 for the total inventory. The convergent validity showed significant negative correlations between HDI and short-form health survey items.
The validity and reliability of the Persian version of the HDI were confirmed. This questionnaire can explore the disabilities of Persian-speaking people with headache disorders.
目前存在少量的头痛残疾指数，可以评估和管理伊朗患者与头痛相关的不同残疾。
本研究旨在翻译和验证亨利福特头痛残疾量表（HDI）的波斯语版本。
对原始问卷进行翻译和文化适应，以适应波斯语环境。共有 250 名慢性头痛患者纳入本研究。评估问卷的表面效度、内容效度和与简明健康调查问卷（SF-36）的收敛效度，并进行验证性因子分析（CFA）。还评估了其内部一致性，并通过组内相关系数（ICC）检查其短期和长期重测信度。
简单性、相关性和清晰度的内容效度指数分别为 0.85、0.99 和 0.97。所有项目的内容效度比均计算为 1。CFA 的结果证实该指数具有良好的拟合度。整个问卷以及其功能和情感子量表的克朗巴赫系数分别为 0.91、0.82 和 0.86。总清单的 ICC 也计算为 0.97。收敛效度显示，HDI 与短式健康调查问卷项目之间存在显著负相关。
波斯语版 HDI 的有效性和可靠性得到了证实。该问卷可用于评估讲波斯语的头痛障碍患者的残疾情况。
