目的：检验骨关节炎（OA）患者5项患者-医生互动（PEPPI-5）量表的结构效度、内部一致性、重测信度和结构效度。方法：224例OA门诊患者的横断面样本完成了一项调查，该调查包含荷兰PEPPI-5和其他标准化措施，评估感知的健康管理技能，一般自我效能，社会支持和健康相关的生活质量。一个子样本的100例患者完成了PEPPI-5再次约3 weeks later.Results：一个一维模型的PEPPI-5的实证因素分析表现出良好的拟合。此外，量表显示出较高的内部一致性（α = 0.92）和公平的重测信度（ICC = 0.68）。正如假设的那样，PEPPI-5与感知的健康管理技能密切相关，与健康的社会支持和心理社会方面适度相关，而与健康的身体方面无关。然而，与预期相反，它是不相关的一般自我efficence.Conclusion：荷兰PEPPI-5表现出足够的有效性和可靠性，在患者OA。实践的影响：PEPPI-5是一个简短的和适当的工具，用于测量自我效能的OA患者与他们的医生互动。需要对其变化的敏感性进行更多的研究，然后才能自信地推荐其作为干预研究的结果指标。(C)2011爱思唯尔爱尔兰有限公司保留所有权利。
Objective: To examine the structural validity, internal consistency, test-retest reliability, and construct validity of the 5-item Perceived Efficacy in Patient-Physician Interactions (PEPPI-5) scale in patients with osteoarthritis (OA).Methods: A cross-sectional sample of 224 outpatients with OA completed a survey containing the Dutch PEPPI-5 and other standardized measures assessing perceived health-management skills, general self-efficacy, social support, and health-related quality of life. A subsample of 100 patients completed the PEPPI-5 again approximately 3 weeks later.Results: Confirmatory factor analysis demonstrated good fit for a unidimensional model of the PEPPI-5. Additionally, the scale showed high internal consistency (alpha = 0.92) and fair test-retest reliability (ICC = 0.68). As hypothesized, the PEPPI-5 was strongly correlated with perceived health-management skills, moderately with social support and psychosocial aspects of health, and not with physical aspects of health. Contrary to expectations, however, it was not correlated with general self-efficacy.Conclusion: The Dutch PEPPI-5 demonstrated adequate validity and reliability in patients with OA.Practice implications: The PEPPI-5 is a brief and appropriate tool for measuring self-efficacy of patients with OA to interact with their physicians. Additional research into its sensitivity to change is needed before it can be confidently recommended as an outcome measure in intervention studies. (C) 2011 Elsevier Ireland Ltd. All rights reserved.
