Pathways analysis of the symptom distress in patients with breast cancer-related lymphoedema and its influencing factors
Objective To explore the mediating role of chronic illness resources and self-care behavior on disease perception and symp-tom distress in patients with breast cancer-related lymphoedema,and to provide a reference for conducting targeted nursing inter-ventions to reduce their symptom distress.Methods A total of 415 outpatients with breast cancer-related lymphoedema were selected using convenience sampling method,then they were investigated by using a general information questionnaire,the Brief Ill-ness Perception Questionnaire(B-IPQ),the Chronic Illness Resources Survey(CIRS),the Breast Cancer Related Lymphedema Self-care Scale(BCRL-SS),and the Breast Cancer and Lymphedema Symptom Experience Index(BCLE-SEI).Results The partici-pants'total score of BCLE-SEI was 75.14±21.38,which was positively correlated with the score of B-IPQ,and was negatively correlated with the score of CIRS and BCRL-SS(all P＜0.05).Chronic illness resources and self-care behavior played mediating role between disease perception and symptom distress,which accounted for 17.36％of the total effect.Conclusions The symptom distress in patients with breast cancer-related lymphoedema is at a medium and low level.Disease perception can directly affect symptom distress,and it can also indirectly affect symptom distress through the chain mediating effects of chronic illness resources and self-care behavior.Medical staff can alleviate the symptom distress of this population via reducing their negative disease per-ceptions,and improving their level of chronic disease resource and self-care behavior.
