12-item QOLIH questionnaire validated for assessing quality of life in idiopathic intracranial hypertension

Key Takeaway
Use the validated 12-item QOLIH questionnaire to assess quality of life in patients with idiopathic intracranial hypertension.

This cross-sectional study aimed to develop and validate an idiopathic intracranial hypertension (IIH)-specific quality of life (QOL) assessment tool. The study was conducted on 146 Egyptian and 156 Turkish patients with IIH. Researchers created a 14-item questionnaire, the Quality of Life in IIH patients questionnaire (QOLIH), with items hypothesized into two domains: activities of daily living (ADL) (items Q1-7 and Q12) and psycho-cognitive function (items Q8-11, Q13, Q14). To assess convergent validity, the study also employed the Visual Analog Scale (VAS), Headache Impact Test-6 (HIT-6), Short Form-12 Health Survey (SF-12), and Low Vision Quality-of-Life Questionnaire (LVQOL). Confirmatory factor analysis revealed that standardized factor loadings were generally acceptable (>0.60) for items Q1-12. However, items Q13 and Q14 consistently displayed weak loadings (<0.60) and were subsequently removed. The final 12-item questionnaire demonstrated acceptable convergent validity with the other QOL measures. The internal consistency of the final questionnaire was high, with Cronbach's alpha values > 0.7. The final Arabic and Turkish versions of the QOLIH questionnaire consist of 12 items. The study concludes that both versions are valid and reliable tools for assessing QOL in IIH patients.

BackgroundPoor quality of life (QOL) has emerged as a key morbidity in patients with idiopathic intracranial hypertension (IIH). This work aimed to develop and validate an IIH-specific quality of life assessment tool.MethodsThis cross-sectional study was conducted on 146 Egyptian and 156 Turkish patients with IIH. A 14-item questionnaire was created to assess QOL in those patients; Quality of Life in IIH patients questionnaire (QOLIH). The questionnaire items were hypothesized into two domains: one domain represents activities of daily living (ADL) (Q1-7 and Q12), and the other domain represents psycho-cognitive function (Q8-11, Q13, Q14). To assess the convergent validity of this questionnaire, the following tests were also employed: the Visual Analog Scale (VAS), Headache Impact Test-6 (HIT-6), Short Form-12 Health Survey (SF-12), and Low Vision Quality-of-Life Questionnaire (LVQOL).ResultsConfirmatory factor analysis (CFA) revealed that standardized factor loadings were generally acceptable (>0.60) for Q1-12. However, Q13 and Q14 consistently displayed weak loadings ( 0.7).ConclusionThe final Arabic and Turkish versions of QOLIH questionnaire consist of 12 items. Both versions are valid and reliable tools that can be used in the assessment of QOL in IIH patients.
