Participants completed a text message\u2010based diary for 4 or 12\u2009weeks (depending on treatment), and a detailed headache assessment on a random 20% of headache days. Using this assessment, we determined whether a headache day qualified for migraine or probable migraine, based on the International Classification of Headache Disorders, 3rd edition (ICHD\u20103).<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>\n                      Of 122 enrolled children and adolescents, 106 (86.9%) completed \u22651 detailed headache assessment (438 entries). We found moderate agreement between self\u2010reported and ICHD\u2010derived migraine day, with a Cohen's Kappa of 0.50 (positive predictive value [PPV]: 0.66; negative predictive value [NPV]: 0.85; correlation: 0.51). Allowing for ICHD\u2010derived probable migraine significantly increased PPV (0.66 vs. 0.94; 95% CI: 0.57\u20130.74 vs. 0.90\u20130.97), but decreased NPV (0.85 vs. 0.293; CI: 0.77\u20130.90 vs. 0.199\u20130.40), Cohen's Kappa (0.50 vs. 0.237; CI: 0. 389\u20130.60 vs. 0.139\u20130.352), and correlation (\n                      <jats:italic>r<\/jats:italic>\n                      \u2009=\u20090.51 vs. 0.302; CI: 0.41\u20130.61 vs. 0.192\u20130.41). Pain severity (OR: 5.7; CI: 2.39\u201313.8), photophobia (OR: 4.1; CI: 1.02\u201316.6), and phonophobia (OR: 7.5; CI: 1.95\u201329.3) were significantly associated with participants' perception of migraine.\n                    <\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion<\/jats:title>\n                    <jats:p>We found only moderate agreement between self\u2010reported and ICHD\u2010derived migraine day, suggesting both measures are not equal but may represent overlapping aspects of migraine as a disease.
