Abstract:
Objective:To explore the mediating role of rehabilitation self-efficacy between outcome expectations and exercise adherence in knee arthroplasty patients.Methods:From June 2023 to May 2024, a total of 205 knee arthroplasty patients from the Department of Orthopedics at the First Affiliated Hospital of Zhengzhou University were selected using convenience sampling. Data were collected using a general information questionnaire, the Hospital for Special Surgery Knee Replacement Expectations Survey (HSS-KRES), the Chinese version of the Self-Efficacy for Rehabilitation Outcome Scale (SER), and the Orthopedic Exercise Adherence Scale (OEAS). Pearson correlation analysis was used to explore the relationships among outcome expectations, rehabilitation self-efficacy, and exercise adherence. Structural equation modeling and mediation analysis were conducted using AMOS 21.0 software.Results:A total of 205 questionnaires were distributed, and 193 valid responses were collected, with an effective response rate of 94.15%. The mean scores for the HSS-KRES, SER, and OEAS were (60.24±5.12), (80.87±11.00), and (33.87±5.49), respectively. Correlation analysis showed that outcome expectations were negatively correlated with rehabilitation self-efficacy and exercise adherence, while rehabilitation self-efficacy was positively correlated with exercise adherence (all P<0.05). Mediation analysis revealed that rehabilitation self-efficacy partially mediated the relationship between outcome expectations and exercise adherence, with a mediation effect estimate of -0.261, accounting for 59.86% of the total effect. Conclusions:Preoperative outcome expectations in knee arthroplasty patients are relatively high, while rehabilitation self-efficacy and exercise adherence are at moderate or lower levels. Rehabilitation self-efficacy serves as a mediating variable between outcome expectations and exercise adherence. Clinical nurses can enhance patients' rehabilitation self-efficacy and manage outcome expectations rationally to improve exercise adherence.
