RESUMEN
Objective To investigate the status quo of health literacy,motivation and self-management behaviours of patients with knee osteoarthritis(KOA),to explore the influence of health literacy and motivation on self-management behaviours to the patients with KOA,and to clarify the relationships among the three factors.Methods Convenience sampling method was used to select 169 KOA patients who were treated in 3 tertiary hospitals in Xianyang between September and December 2021.General status table,chronic disease health literacy scale,patient motivation scale and chronic disease self-management behaviour scale were employed in the on-the-spot survey.Pearson correlation was used to analyze the correlation of health literacy,motivation and self-management behaviour of patients with KOA.Results Total scores of health literacy,motivation and self-management behaviour of the patients with KOA were 79.66±11.91,54.97±9.95 and 23.75±8.89,respectively.It was found that health literacy and motivation of the patients were positively correlated with their self-management behaviour(r=0.872,r=0.822,both P<0.01).Health literacy of the patients was positively correlated with motivation of patients(r=0.877,P<0.01).Health literacy of the patients could be used to directly predict self-management behaviour of patients(β=0.708,95%CI:0.539-0.876),as well as to predict self-management behaviour of the patients through the mediating effect of patient motivation(β=0.228,95%CI:0.676-0.787).The mediating effect accounted for 24.36%of the total effect.Conclusions The health literacy,motivation and self-management behaviours of patients with KOA are all poor and they should be further improved.Patient motivation is the mediating variable in health literacy and self-management behaviour of the patients.It is suggested that nursing staff could encourage the motivation of patients hence to improve the self-management behaviour in the patients with KOA based on an improvement of health literacy.
