Post hoc Dunnett tests comparing the experimental group with the control groups indicated significantly lower itch NRS scores in the positive expectation induction group ( M = 5.7, SD = 0.3) than in the negative expectation induction group ( M = 6.8, SD = 0.3) ( p <0.01) and marginally significant itch NRS scores in the positive expectation induction group than in the extinction group ( M = 6.5, SD = 0.3) ( p = 0.058).
