Reliability of the E-diary diagnosis in combination with two previously validated E-questionnaires was compared to a physician\u2019s diagnosis as gold standard in headache patients referred to the Leiden Headache Clinic (n\u2009=\u2009596). In a subset of patients with migraine (n\u2009=\u2009484), self-estimated migraine-related frequencies were compared to diary-based results.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>The first migraine screening approach including an E-headache questionnaire, and the E-diary revealed a sensitivity of 98% and specificity of 17%. In the second approach, an E-migraine questionnaire was added, resulting in a sensitivity of 79% and specificity of 69%. Mean self-estimated monthly migraine days, non-migrainous headache days and days with acute medication use were different from E-diary-based results (absolute mean difference\u2009\u00b1\u2009standard deviation respectively 4.7\u2009\u00b1\u20095.0, 6.2\u2009\u00b1\u20096.6 and 4.3\u2009\u00b1\u20094.8).<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion<\/jats:title>\n                    <jats:p>The E-diary including algorithms differentiating headache and migraine days showed usefulness in diagnosing migraine. The use emphasised the need for E-diaries to obtain reliable information, as patients do not reliably recall numbers of migraine days and acute medication intake.
