Abstract

Hypnotizability is a stable trait that moderates the benefit of hypnosis for treating pain, but limited availability of hypnotizability testing deters widespread use of hypnosis. Inexpensive genotyping of 4 single nucleotide polymorphisms in the catechol-o-methyltransferase (COMT) gene was performed using giant magnetoresistive biosensors to determine if hypnotizable individuals can be identified for targeted hypnosis referrals. For individuals with the proposed 'optimal' COMT diplotypes, 89.5% score highly on the Hypnotic Induction Profile (OR = 6.12, 95%CI = 1.26-28.75), which identified 40.5% of the treatable population. Mean hypnotizability scores of the optimal group were significantly higher than the total population (p = 0.015 effect size = 0.60), an effect that was present in females (p = 0.0015, effect size = 0.83), but not in males (p = 0.28). In an exploratory cohort, optimal individuals also reported significantly higher postoperative pain scores (p = 0.00030, effect size = 1.93), indicating a greater need for treatment.
