The Headache Needs Assessment (HANA) survey: psychometric properties of the Turkish version in migraine.

This study focused on adapting and validating the Turkish version of the Headache Needs Assessment survey. The survey contains seven items that assess migraine needs. Researchers evaluated structural validity using Exploratory and Confirmatory Factor Analysis with 79 participants. They assessed reliability using Cronbach's α, Intraclass Correlation Coefficient, and Bland-Altman plots. The study analyzed convergent validity by correlating HANA with other headache assessment tools. EFA identified a two-factor structure for HANA A, explaining 69% of variance. A single-factor structure was found for HANA B, confirmed by CFA with acceptable indices. Cronbach's α was above 0.879, indicating high reliability. The ICC ranged from 0.784 to 0.836, showing excellent consistency. HANA correlated moderately to strongly with the Headache Disability Inventory and HIT-6. It showed weak correlation with the Visual Analog Scale and Migraine Disability Assessment. The Turkish HANA demonstrates robust psychometric properties for clinical and research purposes. Clinical relevance: This study confirms that the Turkish HANA survey reliably assesses migraine needs in clinical settings.
