However, there is little research on CH-related disability, and most of it is based on non CH-specific questionnaires. The aim of this study was to develop a short, CH-specific disability questionnaire.<h4>Methods</h4>The 8-item Cluster Headache Impact Questionnaire (CHIQ) was developed based on a literature review and patient and expert interviews. The questionnaire was tested in 254 CH patients (171 males; 47.5 ± 11.4 years; 111 chronic CH, 85 active episodic CH, 52 episodic CH in remission) from our tertiary headache center or from a German support group.<h4>Results</h4>Reliability and validity of the CHIQ was evaluated in active episodic and chronic CH patients (n = 196).
