Background and Purpose Cluster headache (CH) is frequently either not diagnosed or the diagnosis is delayed. We addressed this issue by developing the self-administered Cluster Headache Screening Questionnaire (CHSQ). Methods Experts selected items from the diagnostic criteria of CH and the characteristics of migraine. The questionnaire was administered to first-visit headache patients at nine headache clinics. The finally developed CHSQ included items based on the differences in responses between CH and non-CH patients, and the accuracy and reliability of the scoring model were assessed. Results Forty-two patients with CH, 207 migraineurs, 73 with tension-type headache, and 18 with primary stabbing headache were enrolled. The CHSQ item were scored as follows: 3 points for ipsilateral eye symptoms, agitation, and duration; 2 points for clustering patterns; and 1 point for the male sex, unilateral pain, disability, ipsilateral nasal symptoms, and frequency. The total score of the CHSQ ranged from 0 to 16. The mean score was higher in patients with CH than in non-CH patients (12.9 vs. 3.4, p<0.001). At a cutoff score of >8 points, the CHSQ had a sensitivity, specificity, positive predictive value, and negative predictive value of 95.2%, 96%, 76.9%, and 99.3%, respectively. Conclusions The CHSQ is a reliable screening tool for the rapid identification of CH.
