Lay trainers with migraine for a home-based behavioral training: a 6-month follow-up study

To evaluate the changes at 6-month follow-up after a home-based behavioral training (BT) provided by lay trainers with migraine to small groups of fellow patients.

The need for self-management programs and cost-effective treatments gave rise to this study.

In a previous randomized controlled trial, we compared the BT group with a waitlist-control group, receiving usual care. The control group was trained directly after their waitlist period. The present study examined the follow-up results in both groups and measurements were held pre BT, post BT, and at 6-month follow-up.

Six months after BT, 42% was categorized as responders (>or=-50% decrease in attack frequency), 42% did not change (-49 to 49%), and 16% responded adversely (>or=50% increase). In the group as a whole (n = 95), attack frequency significantly decreased from 3.0 attacks at baseline to 2.5 post BT and to 2.3 at 6-month follow-up (-23%, medium effect size 0.6). The strong improvements of perceived control over and self-confidence in attack prevention were maintained at follow-up. Disability and health status were unchanged but quality of life significantly improved over time (P = .007). BT was more beneficial for patients who entered the training with a high attack frequency. Linear regression analysis demonstrated that a stronger belief at baseline that the occurrence of migraine is due to chance (external control) significantly predicted a lower attack frequency at follow-up.

Lay trainers with migraine can train small groups of fellow patients at home in behavioral attack prevention. At 6-month follow-up, attack frequency and quality of life were significantly but modestly improved and feelings of control and self-confidence remained strongly improved.
