To explore the effects of psychological and cognitive intervention based on stress theory on negative emotions and self-management behavior of patients with osteosarcoma.

A total of 100 patients with osteosarcoma who were admitted to the Affiliated Tumor Hospital of Guangxi Medical University from August 2018 to June 2019 were selected as the research subjects and randomly divided into control group and observation group with 50 patients in each group.Patients in the control group received routine nursing, while patients in the observation group received psychological and cognitive intervention based on stress theory on the basis of routine nursing.The psychological state, disease uncertainty and sleep state of the two groups were compared before and after intervention.

After intervention, the scores of SDS and SAS in the observation group were significantly lower than those in the control group, the scores of various dimensions of disease uncertainty and total scores were significantly lower than those in the control group, and the sleep state score was significantly lower than that in the control group(P<0.05).

Psychological and cognitive behavioral intervention based on stress theory for patients with osteosarcoma can effectively improve their mental state and sleep quality, eliminate the disease uncertainty of patients, and improve the clinical treatment effect.
