The authors asked breast cancer (BC) patients to participate in 1 of 3 mind-body interventions (cognitive-behavioral therapy (CBT), yoga, or self-hypnosis) to explore their feasibility, ease of compliance, and impact on the participants’ distress, quality of life (QoL), sleep, and mental adjustment. Ninety-nine patients completed an intervention (CBT: n = 10; yoga: n = 21; and self-hypnosis: n = 68). Results showed high feasibility and high compliance. After the interventions, there was no significant effect in the CBT group but significant positive effects on distress in the yoga and self-hypnosis groups, and also on QoL, sleep, and mental adjustment in the self-hypnosis group. In conclusion, mind-body interventions can decrease distress in BC patients, but RCTs are needed to confirm these findings.
Clinical evidence for the effectiveness of hypnosis in the treatment of acute procedural pain was critically evaluated based on reports from randomized controlled clinical trials (RCTs). Results from the 29 RCTs meeting inclusion criteria suggest that hypnosis decreases pain compared to standard care and attention control groups and that it is at least as effective as comparable adjunct psychological or behavioral therapies. In addition, applying hypnosis in multiple sessions prior to the day of the procedure produced the highest percentage of significant results. Hypnosis was most effective in minor surgical procedures. However, interpretations are limited by considerable risk of bias. Further studies using minimally effective control conditions and systematic control of intervention dose and timing are required to strengthen conclusions.
