Clinical Hypnosis and Music In Breast Biopsy:A Randomized Clinical Trial

Abstract

A randomized clinical study was conducted to evaluate the effects on anxiety, depression, stress and optimism levels of an audio-recorded clinical hypnosis intervention and a music session and compare them with a control group in women scheduled for breast biopsy. We analyzed the data of 170 patients with an average age of 47 years, who were randomly assigned to each of the groups. The psychosocial variables were measured in three moments: baseline, which corresponds to the period before the intervention with hypnosis, music or waiting in the room before biopsy; a second measurement after the interventions and a third measurement after the breast biopsy procedure was finished. The results showed a statistically significant reduction in the stress (p < .001, η²p = .06); pain, (p < .01, η²p = .04); anxiety, (p < .001, ƞ²p = .07) and depression, (p < .001, ƞ²p = .05) in hypnosis and music groups compared with the control group. Before biopsy, hypnosis decrease significantly pain and depression levels compared with music, but after biopsy there were no differences between both groups. It is recommended to use audio-recorded hypnosis and music interventions to reduce physical and emotional discomfort during the biopsy procedure and to improve the quality of life of patients with suspected breast cancer.
