Instruments to measure change consisted of a self-administered Global Assessment of Recent Stress as well as the Revised Piper Fatigue Scale. Heart rate variability was measured at three time points – at recruitment, before treatment began, (T1), just before the intervention (T2) and 1 week after the intervention (T3).
There were significant decreases in stress (F = 28.45, P < 0.001) and fatigue (F = 26.17, P < 0.001) over time in the experimental group, as compared to the treatment as usual control group.
Additionally, heart rate variability changed over time in the experimental group as compared to the control group; SDNN (F = 6.68, P = 0.002), TP (F = 5.29, P = 0.006), LF (F = 4.58, P = 0.012), and HF (F = 3.71, P = 0.026).
The investigators conclude that guided imagery can be recommended as an effective intervention to thyroid cancer patients experiencing stress and fatigue. The full article is available free.
