Headache disability inventory (HDI): short-term test-retest reliability and spouse perceptions.
We have reported previously that the 25-item Headache Disability Inventory has good internal consistency reliability, robust long-term (2 month) test-retest stability, and good construct validity. We conducted further investigations to evaluate the short-term (1 week) test-retest reliability and spouse perceptions of patients' self-perceived headache disability. The short-term test-retest reliability of the Headache Disability Inventory was excellent. Additionally, the spouse and patients' perceptions of the patient's headache disability generally were congruent, although we observed instances where the differences were marked.
