Objectives:
This study aimed to assess the reliability and validity of the Chinese version of the 10-item Perceived Efficacy in Patient-Physician Interaction (PEPPI-10) scale in hospitalized patients with severe knee osteoarthritis in the People's Republic of China.
Methods:
Between January and March 2015, the Chinese versions of PEPPI, self-efficacy for exercise scale, osteoporosis self-efficacy scale, and modified fall efficacy scale were applied to assess 110 severe knee osteoarthritis patients who were hospitalized in the second ward of the department of arthroplasty surgery of Tianjin Hospital.
Results:
The Chinese version of the PEPPI-10 scale had a high coefficient of internal consistency (Cronbach's α coefficient, 0.907). The score of the Chinese version of PEPPI was weakly correlated with the scores of the Chinese versions of self-efficacy for exercise scale, osteoporosis self-efficacy scale, and modified fall efficacy scale.
Conclusion:
The Chinese version of the PEPPI-10 scale exhibits sufficient internal consistency and convergent validity in hospitalized patients with severe knee osteoarthritis in the People's Republic of China.
