A better understanding of the multi-dimensional burden and impact of migraine has grown over recent years, yet the tools used to measure these concepts have not been updated to reflect such findings. Additionally, due to the increase in the number of both prophylactic and acute therapeutic options for migraine, a comprehensive assessment of treatment response is necessary. The goal of this project was to develop a patient guided outcome measure which evaluates patient identified efficacy factors when appraising migraine treatment response.
A group of patients with migraine (N = 10) were given an in-person semi-structured interview collecting information regarding a patient’s perspective on meaningful response to headache and migraine treatment. Using the patient information collected during these interviews, a set of questions aimed at evaluating meaningful response were developed. Two additional groups (N = 100, 200) of patients with migraine then provided feedback on the drafted questions in an online setting.
Interviews indicated thematic areas of interest to patients with migraine are not commonly assessed on popular measures. Over two hundred items were developed to assess thematic areas indicated by patients. Factor analysis used on the focus groups’ results led to the development of an 18-item scale (Functional Assessment of Migraine Scale-Research: FAMS-R) that assesses the impact of migraine on a patient and shows the potential to measure treatment response.
The FAMS portrays promising results at measuring a multi-faceted migraine treatment response and disease impact.
