Gregoire, C., Bragard, I., Jerusalem, G., Etienne, A.M., Coucke, P., Dupuis, G., . . . Faymonville, M.E. (2017). Group interventions to reduce emotional distress and fatigue in breast cancer patients: A 9-month follow-up pragmatic trial. British Journal of Cancer, 117, 1442–1449.
To determine the long-term (nine months) effectiveness of three different group interventions compared to usual care for patients with breast cancer
Participants were allowed to select one of three groups to receive either cognitive behavioral therapy, yoga, and self-hypnosis. People who declined to participate were in a control group. Measurements were taken T0 through T3 to include before and after the short-term interventions, at month 3, and at month 9 follow-up.
PHASE OF CARE: Multiple phases of care
Three group intervention self-selection; testing at T0, T1, T2 (month 3), T3 (month 9)
Demographics; medical history; Hospital Anxiety Depression Scale (anxiety and depression emotional distress); Quality of Life 30-item questionnaire (fatigue); Insomnia Severity Index (sleep quality)
Only results from baseline (T0) and the month 9 follow-up (T3) were reported using MANOVA with repeated analysis and post-hoc analysis.
Post-hoc comparisons of time T0-T1: hypnosis group showed significant decreases in anxiety (p = 0.000), depression (p = 0.004), and fatigue (p = 0.045). Yoga group showed significant decrease in anxiety (p = 0.01).
Post-hoc comparisons of time at T3: hypnosis group showed decreases in anxiety (p = 0.000), depression (p = 0.000), and fatigue (p = 0.002); yoga group showed decrease in anxiety (p = 0.024).
Self-hypnosis led to improvements in anxiety, depression, and fatigue. Anxiety improved in the yoga group. There were no improvements in the CBT or control groups.
Two of the three interventions may be helpful in reducing anxiety, depression, or fatigue when measured at nine months. Self-hypnosis may help patients improve emotional distress such as depression and anxiety, and may also reduce fatigue; yoga may also help improve anxiety. Larger samples and longer follow-up studies are needed.
