Abstract:Objective To explore the correlation between marital quality status and self-concept in patients with breast cancer undergoing total mastectomy. Methods Using convenience sampling method, 300 female patients with breast cancer who underwent total mastectomy in the Affiliated Hospital of Southwest Medical University from January to July 2022 were selected as the research subjects. General information questionnaire, Locke-Wallace Marriage Adjustment Scale(LWMAT) and Tennessee Self Concept Scale(TSCS) were used to investigate. Results The total score of marital quality in patients with total mastectomy was(95.24±22.99) points. There was a positive correlation between marital quality and self-concept in patients with total mastectomy(r=0.455, P<0.01). The results of multiple linear regression analysis showed that the main caregivers and the total score of self-concept were the influencing factors of marital quality(P<0.05). Conclusion The marital quality of patients with total mastectomy is at a moderate to low level, and self-concept is an important influencing factor of marital quality. Targeted measures should be taken to promote the patients self-concept, improve their mental health level, and thus improve marital quality.
