The Headache Impact Test (HIT-6) questionnaire is commonly utilized to assess the impact of headaches in both clinical settings and research. To date, no validated Spanish version of this tool has been published.
This study seeks to evaluate the psychometric properties of the Spanish version of the HIT-6 questionnaire for use in patients experiencing episodic migraine.
We conducted a cross-sectional study aimed at validating this measurement instrument. A total of 100 subjects, both male and female, aged 18 to 65 years, diagnosed with episodic migraine, were included in the analysis. Construct validity was assessed using principal component analysis, test-retest reliability via the intraclass correlation coefficient (ICC), internal consistency, and convergent validity against the 12-Item Short Form Health Survey and the Migraine Disability Assessment.
The principal component analysis revealed a two-component structure. The overall HIT-6 scale demonstrated strong test-retest reliability ([ICC = 0.89; 95% CI = 0.83-0.92]), with high reliability for the indirect subscale [(ICC = 0.87; 95% CI = 0.81-0.91)] and excellent reliability for the direct subscale [(ICC = 0.90; 95% CI = 0.85-0.93)]. Internal consistency was also robust (Cronbach's α = 0.834), and the questionnaire showed a significant correlation with MIDAS (r = 0.512; p < 0.001), as well as a moderate correlation with the physical (r = -0.326; p < 0.05) and mental factors (r = -0.429; p < 0.001) of the SF-12.
The Spanish adaptation of the HIT-6 questionnaire is a reliable and valid tool for evaluating the impact of episodic migraine on patients' quality of life, confirming the validity of both subscales.
头痛影响测试（HIT - 6）问卷常用于临床和研究中评估头痛的影响。迄今为止，该工具尚无经过验证的西班牙语版本发表。
本研究旨在评估用于发作性偏头痛患者的西班牙语版HIT - 6问卷的心理测量特性。
我们进行了一项横断面研究以验证该测量工具。分析纳入了总共100名年龄在18至65岁之间、被诊断为发作性偏头痛的男女受试者。使用主成分分析评估结构效度，通过组内相关系数（ICC）评估重测信度、内部一致性，并与12项简短健康调查和偏头痛残疾评估进行收敛效度分析。
主成分分析揭示了一个双成分结构。总体HIT - 6量表显示出很强的重测信度（[ICC = 0.89；95% CI = 0.83 - 0.92]），间接子量表具有高信度（[ICC = 0.87；95% CI = 0.81 - 0.91]），直接子量表具有优异信度（[ICC = 0.90；95% CI = 0.85 - 0.93]）。内部一致性也很强（Cronbach's α = 0.834），并且该问卷与偏头痛残疾评估量表（MIDAS）显示出显著相关性（r = 0.512；p < 0.001），与SF - 12的身体（r = -0.326；p < 0.05）和心理因素（r = -0.429；p < 0.001）具有中度相关性。
西班牙语版HIT - 6问卷是评估发作性偏头痛对患者生活质量影响的可靠且有效的工具，证实了两个子量表的有效性。
