Abstract Background: The number of cancer survivors is growing and expected to be 18.9 million by 2024. Addressing survivorship issues, such as sexual health, are a critical part of health promotion. Women diagnosed with breast or gynecologic cancer can experience distressing changes in their self and/or body image, which affects their sexual health. This study evaluates hypnosis compared to progressive muscle relaxation (PMR) to improve self/body image in order to improve sexuality. Methods: Women with a history of breast or gynecologic cancer, who also report negative body image changes, were randomized in a 2:1 fashion to a 6-week intervention of hypnotic relaxation or PMR. Both intervention arms consisted of three 30-minute sessions delivered face-to-face by a trained therapist, one every two weeks, along with home practice using a CD. The primary outcome was impact of treatment on body image using the Impact of Treatment Scale (ITS). Secondary outcomes included mood (Positive/Negative Affect Scale-PANAS), sexual satisfaction (PROMIS satisfaction), and perceived change (Global Impression of Change Scale -GCIS). Outcomes were measured at baseline and 6 weeks except for the GCIS measured only at 6 weeks. A series of independent samples t-tests were used to compare changes in outcome measures between arms. The intention-to-treat principle was applied. Results: The final randomized sample consisted of 87 women. There was no statistically significant difference (p=.15) in the change in ITS between groups at 6 weeks, with both groups significantly improving (within group effect size Cohen's d .49 - .75). There were non-significant differences between groups on secondary outcomes. Change from baseline for positive affect (PANAS) was 1.7 in the hypnosis group and 3.8 in the PMR group while negative affect change was very similar being about 2.8 in both groups. Change from baseline for the PROMIS general sexual satisfaction scale was 1.5 in the hypnosis group and 1.3 in the PMR group. On the GCIS at 6 weeks, 42% of the hypnosis group reported moderate to very much improvement on self/body image (GCIS) while only 32% of the PMR group reported this level of improvement; and 36% of the hypnosis group versus 11% of the PMR group reported moderate to very much improvement in their sexuality. Implications: The stress relieving strategies applied in this study may contribute substantially to decreasing the distress of the cancer experience related to altered self/body image and sexuality. The variable improvement across domains suggests that hypnosis and PMR may work in different ways, mechanistically. Further mechanistic studies of interventions to optimally promote survivorship health are warranted.
