The Effectiveness of Mindful Hypnotherapy on Psychological Inflexibility, Pain Acceptance, Headache Disability and Intensity in Females with Chronic Migraine Headache: A Randomized Clinical Trial

This study was a randomized controlled design and examined the feasibility and effectiveness of mindful hypnotherapy on psychological inflexibility, pain acceptance, headache disability, and headache intensity in patients with chronic migraine headaches. The sample consisted of 38 females with chronic migraine who were randomly assigned to mindful hypnotherapy and medical treatment as usual groups. Psychological inflexibility pain scale (PIPS), chronic pain acceptance questionnaire-revised (CPAQ-R), headache disability inventory (HDI), diary scale for headache, and short-form McGill pain questionnaire 2 (SF-MPQ-2) were administered at baseline and post-treatment in both groups. The psychological inflexibility mean (SD) score was 81.00 (12.15) at baseline, which significantly decreased to 53.28 (17.06) after the intervention (p < 0.001). Additionally, the mean (SD) score of the pain acceptance was 46.44 (11.16), which significantly increased to 73.61 (15.65) in post-intervention (p < 0.001). Furthermore, the mean (SD) score of headache disability was 73.55 (19.48), which significantly decreased to 23.33 (19.88) in post-intervention (p < 0.001). Finally, headache intensity was 7.33 (0.98) and 5.78 (1.83), which significantly decreased to 2.77 (2.04), and 1.38 (1.48) after the intervention based on the Diary Scale for Headache and McGill Pain Questionnaire (SF-MPQ-2), respectively (p < 0.001). In conclusion, the results show that mindful hypnotherapy is a feasible and effective treatment for chronic migraine.
