One-day acceptance and commitment therapy compared to support for depressed migraine patients: A randomized clinical trial

In patients with migraine, depression is associated with poorer medical prognosis, decreased quality of life, and increased risk of suicidality and disability; yet, behavioral interventions have rarely been investigated. The current study compared the efficacy of two 1-day (5- to 6-h) interventions for co-occurring migraine and depression: (1) acceptance and commitment therapy plus migraine education (ACT-ED), and (2) support plus migraine education (S-ED). One hundred and thirty-six patients with comorbid depression and migraine were randomized to a treatment. One hundred and three (76%) completed the ACT-ED (N = 56) or S-ED (N = 47) workshop. Primary outcomes were depression diagnosis and symptoms. Secondary outcomes were anxiety symptoms, headache-related disability and general functioning, and quality of life. Assessments were completed at baseline and 3 and 6 months following the workshop. At the 6-month follow-up, on categorical outcomes, a significantly greater number of people in the ACT-ED condition no longer met criteria for a major depressive episode and exhibited a > 50% drop in symptoms on the Hamilton Rating Scale of Depression. Similarly, though, weaker results were found when examining depressive symptoms dimensionally. On secondary outcomes, people in the ACT-ED condition exhibited significantly greater improvements in anxiety, headache-related disability, and quality of social relationships, compared to S-ED, No differences between groups were observed in general functioning. A 1-day (5- to 6-h) ACT workshop can deliver substantial and lasting benefits to depressed migraineurs, over and above those provided by group support and education. This approach is an attractive alternative to weekly psychotherapy.
