Brief Summary

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.

Conditions

Total Knee Arthroplasty

Outcome Measures

Primary Outcomes (5)

• Postoperative recovery effectiveness

  Postoperative recovery effectiveness: Six months after surgery, the modified Macnab criteria are used for therapeutic evaluation: Excellent indicates complete symptom relief with return to normal daily life and work; Good indicates mild symptoms with slight limitations on daily activities, without adverse effects on daily life and work; Fair indicates significant symptom relief but with limitations on daily activities and adverse effects on daily life and work; Poor indicates no improvement or worsening of symptoms before and after treatment.

  The intervention will be conducted over a period of 6 months.

• Psychological resilience

  Psychological resilience：Evaluated using the Resilience Scale (CD-RISC), which has a Cronbach's α coefficient of 0.875, including three dimensions: strength (10 items, 40 points), optimism (8 items, 32 points), and 韧性 (7 items, 28 points). Each item is scored from 0 to 4 points, with a total score of 100 points, with higher scores indicating better psychological resilience.

  Intervention will take place within 6 months.

• Self-care ability

  The Self-Care Ability Scale (ESCA) was used for evaluation, with a Cronbach's α coefficient of 0.86\~0.92. It consists of 4 dimensions and 43 items, with each item scored on a scale of 0 to 4 points. The total score ranges from 0 to 172, with higher scores indicating stronger self-care ability.

  Intervention will take place within 6 months

• Rehabilitation exercise adherence

  The Functional Exercise Adherence Scale for Orthopedic Patients was used for assessment. This scale consists of 3 dimensions and 15 items, covering exercise adherence related to physical aspects, psychological aspects, and active learning. A 1-5 point Likert 5-point rating scale is used, with a total score of 75 points. Scores \<20 points, 20-55 points, and ≥55 points respectively indicate low adherence, partial adherence, and high adherence.

  Intervention will take place within 6 months

• Family functions

  The Family Function Assessment Scale (APGAR) was used for evaluation, with a Cronbach's α coefficient of 0.856. It consists of 5 items: cooperativeness, adaptability, emotional quality, maturity, and intimacy. Each item is scored out of 10, with higher scores indicating better family function.

  Intervention will take place within 6 months
