Development and validation of the EUROLIGHT questionnaire to evaluate the burden of primary headache disorders in Europe
Abstract
We developed a 103-item self-reporting questionnaire to assess the burden of primary headache disorders on those affected by them, including headache characteristics, associated disability, co-morbidities, disease-management and quality of life. We validated the questionnaire in five languages with 426 participants (131 in UK, 60 in Italy, 107 in Spain, 83 in Germany/Austria, and 45 in France). After a linguistic and a face-content validation, we tested the questionnaire for comprehensibility, internal consistency and test–retest reliability at an interval of one month. In the different countries, response rates were between 73% and 100%. Test–retest reliability varied between –0.27 to 1.0 depending of the nature of the expected agreement. The internal consistency was between 0.69 and 0.91. The EUROLIGHT questionnaire is suitable for evaluating the burden of primary headache disorders, and can be used in English, German, French, Italian and Spanish.

The Eurolight questionnaire is validated for diagnosing migraine, probable migraine, tension-type headache, probable tension-type headache, and probable medication overuse headache according to ICHD-2.
“The Eurolight questionnaire differentiates EH (headache on < 15 days/month) from CH (headache on ≥ 15 days/month) and is validated for diagnosing migraine, probable migraine, TTH, probable TTH, and pMOH according to the International Classification of Headache Disorders, 2nd edition (ICHD-2) [17] and for assessing the impact of headache disorders [16].”

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
