Objective To explore the effects of acceptance and commitment therapy on psychological resilience and perceived benefit of breast cancer patients.Methods From January to June in 2015,39 inpatients were enrolled as the control group,where routine nursing and functional exercise were carried out.From July 2015 to January 2016,41 inpatients were treated as the observation group,where acceptance and commitment therapy was implemented apart from the treatment for the control group.Before and after the intervention,the Conor-Davision resilience scale (CD-RISC) and the Chinese version of perceived benefits of diagnosis and treatment of breast cancer (PB-DTBC) were used for evaluation.Result After the intervention,the scores of psychological resilience and the perceived benefit of the observation group were significantly higher than those of the control group and before intervention (P＜0.01).Conclusion Acceptance and commitment therapy can effectively improve the psychological resilience and disease-perceived benefit of breast cancer patients.
