The ABC-X model is a systematic intervention approach based on stress source analysis and adaptation theory. It emphasizes the dynamic interaction between stressors (A), coping resources (B), cognitive appraisal (C), and crisis outcomes (X). By systematically assessing patients' psychosocial stress, integrating family and social support resources, and optimizing disease cognition, it helps patients and their families alleviate psychological pressure and cope with disease challenges. This study aims to explore the impact of nursing interventions based on the ABC-X model on coping styles and family functioning in patients after total knee arthroplasty.
