Educational Video Program to Promote Physical Activity and Reduce Migraine Frequency in Adults With Migraine

The Headache Impact Test (HIT-6) is a validated questionnaire used to assess the impact of headaches on a person's ability to function in daily life. It includes six questions covering domains such as pain, social functioning, role functioning, vitality, cognitive functioning, and psychological distress. Each item is scored on a scale, and the total score ranges from 36 to 78, with higher scores indicating greater impact of headaches. In this study, HIT-6 was used as the primary outcome measure to evaluate the effect of the video-based educational intervention on migraine-related disability. Scores were collected at baseline and again six months later, three months after the intervention period ended, to assess any changes in the perceived impact of migraine on participants' lives.

Three physical activity indices (PAI) were used to evaluate changes in participants' activity levels: job-related PAI, housework, house maintenance, and caring for family-related PAI, and recreation, sport, and leisure time-related PAI. These indices are derived from validated self-report questionnaires and reflect both the intensity and frequency of physical activity in different contexts. This outcome aimed to assess whether the video-based educational intervention led to meaningful behavioral changes regarding physical activity. Measurements were taken at baseline and again at 6-month follow-up, corresponding to three months after the completion of the video series.

Migraine frequency was measured as the number of self-reported migraine days per month. This secondary outcome aimed to evaluate whether the educational video program contributed to a reduction in the frequency of migraine attacks. Participants recorded their migraine occurrences in headache diaries, and data were collected at baseline and at the 6-month follow-up to compare the frequency before and after the intervention.

This outcome measures how often participants used acute medication (e.g., analgesics or triptans) to treat migraine attacks each month. The goal was to determine whether the video-based educational program reduced the need for acute migraine medication. Participants kept monthly medication logs, and frequency data were collected at baseline and again at the 6-month follow-up to evaluate the impact of the intervention.

At the 6-month follow-up, participants' perceived overall change in their migraine condition was assessed using an adapted version of the Patient Global Impression of Change (PGIC) scale. This version was translated and culturally adapted to Portuguese and asked participants to rate how their condition had changed since the beginning of the study. Response options ranged from "no changes (or worsening of the condition)" to "much better." The PGIC is a validated, subjective measure commonly used in chronic condition trials to evaluate patients' impressions of treatment effectiveness. This outcome aimed to capture participants' global self-assessment of improvement or deterioration after the educational video intervention.
