Objective To systematically evaluate the intervention effect of acceptance and commitment therapy on breast cancer patients. Methods A systematic search of databases, including the Cochrane Library, Web of Science, PubMed, Embase, CINAHL, PsycInfo, CNKI, WanFang Data and CBM, was carried out to collect randomized controlled trials on acceptance and commitment therapy on breast cancer patients from inception to August, 2021. There were 2 researchers who screened the literature according to inclusion and exclusion criteria, extracted data and evaluated the methodological quality. Meta-analysis was conducted with Revman5.4 software. Results A total of 13 randomized controlled studies were included, involving 1061 patients. Meta-analysis showed that acceptance and commitment therapy was superior to conventional care on improving depression [SMD=-1.15, 95%CI(-1.48, -0.82), P<0.001], anxiety [SMD=-1.28, 95%CI(-1.53, -1.04), P<0.001], psychological flexibility [MD=-12.26, 95%CI(-15.02, -9.51), P<0.001] and post-traumatic growth [MD=-12.48, 95%CI(-13.55, -11.40), P<0.001], and perceived benefit of disease[MD=-8.77, 95%CI(-10.79, -6.75), P<0.001] of breast cancer patients. Conclusion Acceptance and commitment therapy can relieve depression and anxiety, improve psychological flexibility and post-traumatic growth, and enhance the perceived benefit of disease. It plays a positive role in the improvement of mental state of breast cancer patients.

Objective To systematically evaluate the qualitative research about experience of patients and caregivers on self-care,so as to provide references for better developing and improving stroke self-care intervention programs and promoting physical and mental health of stroke survivors and caregivers. Methods PubMed,Web of Science,Embase,PsycINFO,CINAHL,Cochrane Library,Joanna Briggs Institute（JBI）,CNKI,Wanfang database and other Chinese and English databases were searched by computer to screen qualitative studies related to stroke survivors / caregivers and self-care. The retrieval time was from the establishment of the databases to June 2021. Joanna Briggs Institute evidence-based health care center quality evaluation tool was used to evaluate the methodological quality of the included literature,and the results were integrated by meta-integration method. Results A total of 12 studies were included,and 46 clear research results were extracted. The similar research results were summarized into 11 new categories,and 3 integrated results were synthesized：understanding of the concept,significance and influencing factors of self-care by stroke survivors and caregivers;perceptions of stroke survivors and caregivers on skills and strategies related to self-care;views of stroke survivors and caregivers on the acceptability and sustainability of self-care support. Conclusion Views and expectations of stroke survivors and caregivers on self-care are important. In the future,dyadic self-care support programs for stroke survivors and caregivers can be carried out,and the advantages of digital technology and platforms can be used to enrich the forms and contents of self-care interventions and form more targeted self-care interventions.
