Parallel and serial mediation analysis between pain, anxiety, depression, fatigue and nausea, vomiting and retching within a randomised controlled trial in patients with breast and prostate cancer
Objective Cancer treatment is a particularly stressful period for the
patient. The reasons vary and include fear of treatment outcome as well
as treatment induced side effects. The patient frequently experiences
simultaneously various side effects resulting in a diminishing of the
patient's health-related quality of life (HRQoL). The study provides
evidence on the co-occurrence and inter-relations between pain, anxiety,
depression and fatigue in patients with breast and prostate cancer.
Design This paper presents a secondary analysis of the data from a
randomised control trial designed to test the effectiveness of guided
imagery and progressive muscle relaxation on pain, fatigue, anxiety and
depression. Non-parametric bootstrapping analyses were used to test the
mediational model of anxiety, fatigue and depression as parallel
mediators of the relationship between pain and HRQoL. Setting The study
was undertaken at the home setting. Participants In total 208 patients
were included in the study (assigned equally in two groups), referred at
the outpatient clinics of the three participating cancer care centres.
Results The three mediators fully mediate the relationship between pain
and HRQoL indirect effect (IE overall =-0.3839, 95% CI: Lower limit
(LL)=-0.5073 to upper limit (UL)=-0.2825) indicating that patients with
increased pain are likely to have higher levels of anxiety, fatigue and
depression. Gender significantly moderated the mediational effect of
Fatigue Index of Moderated Mediation (IMM=-0.2867 SE=0.1526, LL=-0.6127,
UL=-0.0226) but did not moderate mediational effect of anxiety
(IMM=-0.0709, SE=0.1414, LL=-0.3459, UL=+0.2089). The results show that
the three mediators in a serial causal order fully mediate the
relationship between pain and HRQoL (IE overall =-0.384, 95% CI:
LL=-0.51 to UL=-0.284) and the ratio of the overall indirect effect to
the total effect is 0.8315 (95% CI: LL=0.5683 to UL=1.1718). Conclusion
This work provides evidence that targeting fatigue, anxiety and
depression may have a meaningful effect on pain as a related symptom and
potentially have a positive impact on HRQoL of patients with breast and
prostate cancer.</p
A Randomized Controlled Trial for the Effectiveness of Progressive Muscle Relaxation and Guided Imagery as Anxiety Reducing Interventions in Breast and Prostate Cancer Patients Undergoing Chemotherapy
Objective. To test the effectiveness of guided imagery (GI) and progressive muscle relaxation (PMR) as stress reducing interventions in patients with prostate and breast cancer who undergo chemotherapy. Methods. Patients were randomly assigned to either the control group or the intervention group (PMR and GI). Patients were observed for a total duration of 3 weeks and assessed with the SAS and BECK-II questionnaires for anxiety and depression, respectively, in addiotion to two biological markers (saliva cortisol and saliva amylase) (trial registration number: NCT01275872). Results. 256 patients were registered and 236 were randomly assigned. In total 104 were randomised to the control group and 104 to the intervention group. Intervention's mean anxiety score and depression score changes were significantly different compared to the control's (b=-29.4, p<0.001; b=-29.4, p<0.001, resp.). Intervention group's cortisol levels before the intervention (0.30±0.25) gradually decreased up to week 3 (0.16±0.18), whilst the control group's cortisol levels before the intervention (0.21±0.22) gradually increased up to week 3 (0.44±0.35). The same interaction appears for the Amylase levels (p<0.001). Conclusions. The findings showed that patients with prostate and breast cancer undergoing chemotherapy treatment can benefit from PMR and GI sessions to reduce their anxiety and depression. © 2015 Andreas Charalambous et al

Visualization and relaxation as anxiety reducing techniques in breast and prostate cancer patients undergoing chemotherapy: Findings from a randomized controlled trial
Guided imagery and progressive muscle relaxation as a cluster of symptoms management intervention in patients receiving chemotherapy: A randomized control trial
Objective: Patients receiving chemotherapy often experience many different symptoms that can be difficult to alleviate and ultimately negatively influence their quality of life. Such symptoms include pain, fatigue, nausea, vomiting and retching, anxiety and depression. There is a gap in the relevant literature on the effectiveness of cognitive-behavioural and relaxation techniques in symptom clusters. The study reflects this gap in the literature and aimed to test the effectiveness of Guided Imagery (GI) and Progressive Muscle Relaxation (PMR) on a cluster of symptoms experienced by patients undergoing chemotherapy. Methods: This was a randomized control trial with 208 patients equally assigned either in the intervention or the control group. Measurements in both groups were collected at baseline and at completion of intervention (4 weeks). Patients were assessed for pain, fatigue, nausea, vomiting and retching, anxiety and depression. The overall management of the cluster was also assessed based on the patients' self-reported health related quality of life-HRQoL. Chisquare tests (X2), independent T-tests and Linear Mixed Models were calculated. Results: Patients in the intervention group experienced lower levels of Fatigue (p &lt;0.0.0225), and Pain (p = 0.0003) compared to those in the control group and experienced better HRQoL (p &lt;0.0001) [PRE-POST: Intervention: Pain 4.2(2.5) - 2.5(1.6), Fatigue 27.6(4.1) - 19.3(4.1), HRQoL 54.9(22.7) - 64.5(23), Control: Pain 3.5(1.7) - 4.8(1.5), Fatigue 28.7(4.1) - 32.5(3.8), HRQoL 51.9(22.3)- 41.2(24.1)]. Nausea, vomiting and retching occurred significantly less often in the intervention group [pre-post: 25.4(5.9)- 20.6(5.6) compared to the control group (17.8(6.5)- 22.7(5.3) (F = 58.50 p &lt;0.0001). More patients in the control group (pre:n = 33- post:n = 47) were found to be moderately depressed compared to those in the intervention group (pre:n = 35-post:n = 15) (X2 = 5.93; p = 0.02). Conclusion: This study provided evidence that the combination of GI and PMR can be effective in the management of a cluster of symptoms in cancer patients receiving chemotherapy. These techniques can complement existing management measures to achieve a comprehensive management of this symptom cluster and increase patients HRQoL. © 2016 Charalambous et al.This is a
