Structural equation modeling showed that caregiver burden mediated the relation between patients' dispositional mindfulness and negative emotions. CONCLUSION BC patients with higher levels of dispositional mindfulness showed less negative emotions. The results of the mediation analysis suggested that higher levels of dispositional mindfulness of breast cancer patients could decrease the caregivers' perceived burden and, in turn, relieve patients' negative emotions. Dispositional mindfulness was beneficial to breast cancer patients as well as their caregivers, indicating that mindfulness-based interventions targeting distress in patient-caregiver dyads would be more effective than what interventions for patients alone.PURPOSE Previous systematic review suggested a beneficial effect of progressive muscle relaxation (PMR) for cancer patients receiving chemotherapy. However, poor quality of eligible studies which included in previous systematic review impaired the reliability and validity of findings. The aim of the present systematic review was to further assess the value of PMR in chemotherapy-induced nausea and vomiting. METHODS We assigned two independent investigators to search potential studies in PubMed, Cochrane Controlled Register of Trial (CENTRAL), Cumulative Index to Nursing and Allied Health Literature (CINAHL), China Biomedical Literature database (CBM), China National Knowledge Infrastructure (CNKI), and Wanfang Data database. We used data extraction sheet to extract essential information, and used the Cochrane risk of bias assessment tool to appraise the quality of eligible studies. Finally, we qualitatively summarized the results of all included studies. RESULTS Six studies enrolling 288 patients were included finally. Of these 6 studies, thr
