Phase II randomized controlled trial of hypnosis versus progressive muscle relaxation for body image after breast or gynecologic cancer.

BACKGROUND

Sexual dysfunction, fueled by body image stress, is prevalent in women with a history of breast or gynecologic cancer. Preliminary data support that mind-body connections may improve sexual health outcomes through improving body image.

OBJECTIVE

This randomized controlled trial compared hypnosis to progressive muscle relaxation (PMR). The primary outcome was body image at week 6 as measured by the Impact of Treatment Scale for women who have or have had breast or gynecologic cancer.

INTERVENTIONS/

METHODS

Consented participants were randomized 2:1 to hypnosis or PMR. Both arms consisted of three face-to-face sessions delivered by a trained therapist. Sessions were every 2 weeks for 6 weeks; participants practiced at home between sessions using an audio recording.

RESULTS

Eighty-seven women were randomized, 59 to hypnosis and 28 to PMR. Both groups reported significant improvements on body image over time (within group effect size Cohen's d = 0.49-0.75) with no significant difference between groups (p = 0.15). Secondary outcomes were not significantly different between groups. The hypnosis group improved more in sexual satisfaction and sexual interest while the PMR group improved more in positive affect.

CONCLUSIONS

Interventions facilitating mind-body connections such as hypnosis and PMR may help to improve body image. This study suggests that stress relieving strategies of hypnosis and PMR may contribute to providing a re-connection to one's body, improved positive affect, and overall better sexual health.
