Objective: To better characterize the ways that migraine affects multiple domains of life.Background: Further understanding of migraine burden is needed. Methods: Adults with migraine randomized to mindfulness-based stress reduction or headache education arms (n = 81) in two separate randomized clinical trials participated in semistructured in-person qualitative interviews conducted after the interventions. Interviews queried participants on migraine impact on life and were audio-recorded, transcribed, and summarized into a framework matrix. A master codebook was created until meaning saturation was reached and magnitude coding established code frequency. Themes and subthemes were identified using a constructivist grounded theory approach. Results: Despite most participants being treated with acute and/or prophylactic medications, 90% (73/81) reported migraine had a negative impact on overall life, with 68% (55/81) endorsing specific domains of life impacted and 52% (42/81) describing impact on emotional health. Six main themes of migraine impact emerged: (1) global negative impact on overall life; (2) impact on emotional health; (3) impact on cognitive function; (4) impact on specific domains of life (work/career, family, social); (5) fear and avoidance (pain catastrophizing and anticipatory anxiety); and (6) internalized and externalized stigma. Participants reported how migraine (a) controls life, (b) makes life How to cite this article:

Objective: To understand the mechanisms of mindfulness' impact on migraine.Background: Promising mindfulness research demonstrates potential benefit in migraine, but no data-driven model exists from the lived experiences of patients that explains the mechanisms of mindfulness in migraine.Methods: Semi-structured qualitative interviews were conducted with adults with migraine who participated in two mindfulness-based stress reduction (MBSR) clinical trials (n = 43). Interviews were audio-recorded, transcribed, and summarized into a framework matrix with development of a master codebook. Constructivist grounded theory approach was used to identify themes/subthemes. Results:Participants who learned mindfulness techniques through MBSR experienced altered pain perception, altered response to migraine attacks and disease, increased awareness of external and internal experiences, improved overall well-being, and group benefits. Mindfulness resulted in earlier stress-body awareness and increased interoceptive awareness resulting in earlier attack recognition, leading to earlier and more effective management. Interictal factors of self-blame, guilt, and stigma decreased while migraine acceptance, hope, empowerment, self-efficacy, and selfcompassion increased. Improved emotion regulation resulted in decreased fear of migraine, pain catastrophizing, anticipatory anxiety, and pain reactivity. Although taught as prevention, mindfulness was used both acutely and prophylactically. We created a conceptual model hypothesizing that MBSR skills led to an infusion of mindfulness in daily life, resulting in altered pain perception and experience, ultimately leading to improvement in overall well-being, which may positively feed back to the infusion of mindfulness in daily life. The therapeutic benefit of learning mindfulness in a group setting may moderate these effects. Conclusions:This study identified several new potential mechanisms of mindfulness' effect on migraine. After learning MBSR skills, participants reported altered pain and
