To test the effectiveness of progressive muscle relaxation (PMR) and guided imagery as stress-reducing interventions
Patients randomized to usual care had weekly meetings with psychologists. Those randomized to PMR and guided imagery had four supervised sessions and daily self-practice for three weeks. To stimulate imagery, the guided imagery component included auditory, tactile, and olfactory images. The imagery script was accompanied by music. The intervention was tested and measured with biofeedback prior to study use. Both groups were assessed at baseline and at the end of three weeks. Daily text message reminders were sent to the intervention group to remind them to practice PMR.
The group had a decrease in mean anxiety score whereas the control group had an increase in anxiety at three weeks compared to baseline. The difference between groups of this change was significant (p < 0.001). The same pattern of change between groups was shown for depression (p < 0.001). Salivary amylase and cortisol levels were directly related to anxiety and depression scores (p < 0.001).
PMR and guided imagery were associated with reduced anxiety and depression among patients with breast and prostate cancer during chemotherapy.
Findings here showed that progressive muscle relaxation and guided imagery were effective in reducing anxiety and depression during chemotherapy treatment. These are very low-risk interventions that can be helpful and can be readily incorporated into standard patient care.
