The HIT-6 Questionnaire Corresponds to the PedMIDAS for Assessment of Pediatric Headaches.

Objective: The aim of our study was to compare two questionnaires regarding their ability to globally assess the impact of headaches on daily functioning in children as a primary endpoint and, secondarily, to evaluate their correlation to frequency and headache strength. Background: Headache is a common complaint in children and adolescents, leading to functional impairment. The impact of primary headaches, such as migraine and tension-type headaches, varies according to pain severity and frequency. Although the PedMIDAS questionnaire is a validated tool for assessing headache-related impact in children, it can be difficult for children to complete. The HIT-6 questionnaire is user-friendly but has been validated exclusively for use in adults. Methods: Our method involved a prospective cohort study in children aged 6-18 years who visited the headache clinic at Bnai Zion Medical Center due to primary headaches. All children filled in both the PedMIDAS and HIT-6. Data on headache diagnosis, frequency and intensity along with demographic data were obtained. Results: Of the 100 children participating, 96 completed both questionnaires. The final sample was 66% (63) female, and the average age was 14 years (±3.3). Migraine was reported by 62% (60), followed by tension-type headaches (18%) and mixed headache (15%). A weak positive spearman correlation was observed between PedMIDAS and HIT-6 scores to age (respectively, ρ 0.3 with p value < 0.005, and ρ 0.2 with p value < 0.05), a weak positive spearman correlation as well between the HIT-6 score and both disease duration and headache intensity (respectively, ρ 0.221 with p value < 0.05 and ρ 0.250 with p value < 0.05). PedMIDAS score was weakly positively correlated to headache frequency (ρ 0.27 with p value < 0.05). A moderately positive spearman correlation was found between the PedMIDAS and HIT scores with ρ 0.6 and p value < 0.005. Linear regression analysis revealed a stronger correlation with headache frequency for the HIT-6 than for the PedMIDAS, when adjusted to gender and headache type. Conclusions: The HIT-6 questionnaire correlates with the PedMIDAS questionnaire and can serve as a good alternative for easily evaluating headache burden in children.
