This study aimed to investigate the contemporary status and influencing factors of foot self-care behavior in diabetic foot amputation patients. A total of 250 patients with diabetic foot amputation were included. The general information questionnaire, Chinese Version of the Nottingham Assessment of Function Footcare (CNAFF), Knowledge of Diabetic Foot Questionnaire, and The Third Version of the Diabetes Attitude Scale were used to investigate the status and influencing factors of foot self-care behavior in patients with diabetic foot amputation. From our sample, the Chinese version of Nottingham foot care behavior score was 68.32 ± 10.35 points, which showed that the foot self-care behavior of patients with diabetic foot amputation is at a medium level. Multiple linear regression analysis showed that education level, the knowledge of how to choose shoes and socks, the knowledge of self-care for feet, the need for special training in education, and the patient's autonomy in diabetes care were the main factors influencing foot self-care behavior of patients with diabetic foot amputation (P < 0.05). The total variation of CNAFF score was 49%. The results of this study show that the level of foot care of diabetic amputees must be improved, and medical staffs need to take targeted intervention measures to help patients improve their self-care behavior after amputation, thereby reducing the recurrence rate of diabetic feet and improving their quality of life.
