This randomized controlled trial examined mechanisms and moderators of outcomes after 8-week mindfulness-based cognitive therapy (MBCT) or supportive-expressive sex education therapy (STEP) for sexual dysfunction in 116 breast cancer survivors (mean age 49.9 ± 9.5 years). Participants completed assessments before treatment, immediately afterward, and 6 months later. Increased pain acceptance mediated improvements in sexual desire and reductions in sexual distress and vaginal pain; reduced pain catastrophizing mediated lower sexual distress. Treatment expectations and baseline anxiety, depression, and age were among factors associated with differences in outcomes.
Key findings
- Increased pain acceptance mediated improved sexual desire and reduced sexual distress and vaginal pain.
- Reduced pain catastrophizing mediated improvement in sexual distress.
- Higher treatment expectations were associated with greater reductions in sexual distress; low baseline anxiety was associated with greater improvements in desire and distress.
- Low baseline depression predicted greater improvement in desire only in STEP; older STEP participants improved more than younger participants.
Why it matters
The findings suggest that pain-related beliefs and acceptance may be relevant targets when addressing sexual dysfunction after breast cancer. They also indicate that outcomes can vary with patient characteristics and expectations, and that these relationships may differ between treatment approaches. Understanding such factors may help clinicians interpret treatment response and inform further evaluation of tailored support.
