German Translation and Cross-cultural Adaptation of the Headache Screening Questionnaire (HSQ) Followed by a Test-retest Reliability Study.

The Dutch Headache Screening Questionnaire (HSQ) is the only screening questionnaire based on ICHD-3 which has at least moderate confidence in its criterion validity according to GRADE. The HSQ has already been translated into Portuguese and validated5. The HSQ has only 8 items and requires little time to complete. Due to its good sensitivity, the HSQ screening questionnaire is particularly well suited to exclude migraine.
