Participants with CDH (\n N<\/jats:italic>\n \u2009=\u200979) completed the CHASE, Headache Management Self\u2010Efficacy Scale (HMSE), six\u2010item Headache Impact Test\u20106 (HIT\u20106), and 12\u2010item Short Form Health Survey (SF\u201012) at baseline, 24\u201372\u2009h after baseline, and 12\u2009weeks after baseline. The Global Rating of Change (GROC) assessed perceived change in symptoms. We assessed internal consistency, day\u2010to\u2010day reliability, convergent and known group discriminant validity, dimensionality, and responsiveness via minimal clinical important difference (MCID).\n <\/jats:p>\n <\/jats:sec>\n \n Results<\/jats:title>\n \n For day\u2010to\u2010day reliability, the CHASE intraclass correlation coefficient was 0.68 (95% confidence interval 0.49\u20130.81), with standard error of measurement and minimal detectable change of 10.3% and 24%, respectively. The CHASE had two independent factors (total\n R<\/jats:italic>\n 2<\/jats:sup>\n \u2009=\u200954.5%) that can be combined into a single score (Cronbach's alpha internal consistency 0.88). For convergent validity, the CHASE score was related to the HIT\u20106, HMSE, and SF\u201012 (\n R<\/jats:italic>\n 2<\/jats:sup>\n : 0.17\u20130.29, all\n p<\/jats:italic>\n \u2009<\u20090.001). For known group discriminant validity, individuals with an active headache had a lower CHASE score than those without (mean [standard deviation] 47.7\u2009[17.3]% vs. 57.2\u2009[19.8]%,\n p<\/jats:italic>\n \u2009<\u20090.001). Classification and regression tree analysis showed the MCID for meaningful positive symptom change on the GROC was a CHASE change of >8% or CHASE change of 8% with baseline CHASE >67%.\n <\/jats:p>\n <\/jats:sec>\n \n Conclusion<\/jats:title>\n The CHASE is a reliable and valid questionnaire for assessing self\u2010efficacy in performing daily activities, socializing, managing headache symptoms
