Types of Triggers in Migraine - Factor Structure of the Headache Triggers Sensitivity and Avoidance Questionnaire and Development of a New Short Form (HTSAQ-SF).

Both the long and short forms of the questionnaire appear to be reliable and valid measures. The development of the short form of the questionnaire simplifies the use of the HTSAQ in clinical practice. Further research should focus on other primary headache disorders, such as tension-type headache or cluster headache.
