Objective To investigate the effects of pulmonary rehabilitation training based on Snyder′s hope theory on hope level, self-care ability and survival status of patients with chronic obstructive pulmonary disease (COPD).Methods A total of 132 COPD patients were randomly divided into an experimental group and a control group, with 66 patients in each group.The control group received respiratory routine care, and the experimental group received pulmonary rehabilitation training based on Snyder′s hope theory in addition to routine care.Herth Hope Index (HHI), Exercise of Self-care Agency Scale (ESCA), and BODE index were used to evaluate the two groups before intervention and after 4 and 12 weeks of intervention.Results After the intervention, the scores of HHI and ESCA in experimental group were significantly higher than those in control group, and the score of BODE index was significantly lower than that in control group （all P＜0.05）.Conclusion Pulmonary rehabilitation training based on Snyder′s hope theory can effectively improve the hope level and self-care ability of COPD patients, and improve their survival status.
