N2 - Background: Good self-management behaviors in patients with knee osteoarthritis can improve disease awareness, treatment effectiveness, quality of life, and reduce medical costs. However, there is a paucity of studies focusing on patients with knee osteoarthritis. Therefore, the purpose of this study was to explore the mediating effect of self-efficacy on aspects of social support and self-management behaviors in this population. Methods: This study employed a cross-sectional design and convenience sampling to survey patients with knee osteoarthritis in an outpatient department of a regional hospital in northern Taiwan from February 22, 2021, to April 15, 2021. The inclusion criteria for patients were (1) those diagnosed by a physician with knee osteoarthritis and (2) who could communicate in Chinese or Taiwanese. Participants were asked to complete a demographic questionnaire, the Arthritis Self-Efficacy Scale (ASE), the Inventory of Socially Supportive Behavior (including enacted support and perceived social support), and the Arthritis Self-Management Assessment Tool (ASMAT). In addition, the Kellgren-Lawrence Grading Scale was obtained from a chart review. Data were analyzed with descriptive statistics, t-test, one-way analysis of variance, Pearson product-moment correlation, and mediation analysis. Results: A total of 140 patients met the inclusion criteria. The mean age of participants was 70.21 ± 10.84years; most (73.6%) were female. The mean total score of the ASMAT was 64.27 ± 14.84. Scores for the ASE, enacted support, and perceived social support were significantly positively correlated with ASMAT (all p <.001). The standardized coefficient for total effect and direct effect of perceived social support on ASMAT was 0.899 (p <.001) and 0.754 (p <.05), respectively. After introducing the ASE into the model, the indirect effect was 0.145 (p <.05), which indicated that ASE had a partial mediating effect on the relationship between perceived social support and ASMAT. Conclusion: Our findings might suggest that perceived social support indirectly affected ASMAT through ASE. Therefore, interventions designed to increase self-efficacy and social support could enhance self-management behaviors for patients with knee osteoarthritis.
