RESUMO
BACKGROUND: Behavioral migraine approaches are effective in reducing headache attacks. Availability of treatment might be increased by using migraine patients as trainers. Therefore, Mérelle and colleagues developed and evaluated a home-based behavioral management training (BMT) by lay trainers (1). The maintenance of effects at long-term follow-up is studied in the present study. METHOD: Measurements were taken pre-BMT (T0), post-BMT (T1), at six-month follow-up (T2), and at long-term follow-up, i.e. two to four years after BMT (T3). Data of 127 participants were analyzed with longitudinal multi-level analyses. RESULTS: Short-term improvements in attack frequency and self-efficacy post-BMT were maintained at long-term follow-up ( DT0T3 = -.34 and DT0T3 = .69, respectively). The level of internal control that increased during BMT decreased from post-BMT to long-term follow-up ( DT0T3 = .18). Quality of life and migraine-related disability improved gradually over time ( DT0T3 = .45 and DT0T3 = -.26, respectively). CONCLUSIONS: Although the results should be interpreted with caution because of the lack of a follow-up control group and the inability to gather information about additional treatments patients may have received during the follow-up period, the findings suggest that lay BMT for migraine may be beneficial over the long term. If so, this could make migraine treatments more widely available.
