While the importance of outpatient physician-patient interaction is increasingly recognized, there remains a lack of effective tools to assess these interactions in mainland China. This gap limits our understanding of the nuances in outpatient physician-patient interactions.
This study aimed to translate the Questionnaire on the Quality of Physician-Patient Interaction (QQPPI) into Chinese and validate its effectiveness in assessing the quality of outpatient physician-patient interactions.
This study recruited 466 outpatients using convenience sampling and was conducted in four phases: (1) translation and back-translation to develop the Chinese version of the QQPPI (QQPPI-C); (2) expert review for cultural and contextual relevance; (3) psychometric validation, including exploratory factor analysis on 140 participants and confirmatory factor analysis, measurement invariance, and convergent validity on the remaining 326; and (4) internal consistency assessment using Cronbach's α and Guttman's λ₄.
Among the 466 participants (mean age 48.89 ± 14.93 years; 50.2 % male), 140 were randomly assigned for exploratory factor analysis, which supported a unidimensional scale structure explaining 52.12 % of the variance. The remaining 326 participants were used for confirmatory factor analysis and other validity assessments. confirmatory factor analysis indicated good model fit (χ²/df = 2.338, Root Mean Square Error of Approximation = 0.064, Incremental Fit Index = 0.937, Comparative Fit Index = 0.963, Tucker-Lewis Index = 0.955, and Root Mean Square Residual = 0.031). The QQPPI-C showed excellent internal consistency (Cronbach's α = 0.939, Guttman's λ₄= 0.940), high content validity (scale-level content validity index = 0.968), adequate convergent validity, and measurement invariance across genders.
The QQPPI-C is a reliable and valid tool for assessing outpatient physician-patient interaction quality in China. Its use can support clinical communication improvement and research on patient-centered care.
虽然门诊医患互动的重要性日益得到认可，但在中国内地仍缺乏评估这些互动的有效工具。这一差距限制了我们对门诊医患互动细微差别的理解。
本研究旨在将医患互动质量问卷（QQPPI）翻译成中文，并验证其在评估门诊医患互动质量方面的有效性。
本研究采用便利抽样法招募了466名门诊患者，研究分四个阶段进行：（1）翻译和回译以制定QQPPI中文版（QQPPI-C）；（2）专家评审以确保文化和背景相关性；（3）心理测量学验证，包括对140名参与者进行探索性因素分析，以及对其余326名参与者进行验证性因素分析、测量不变性分析和收敛效度分析；（4）使用Cronbach's α和Guttman's λ₄进行内部一致性评估。
在466名参与者中（平均年龄48.89±14.93岁；50.2%为男性），140名被随机分配用于探索性因素分析，结果支持单维量表结构，该结构解释了52.12%的方差。其余326名参与者用于验证性因素分析和其他效度评估。验证性因素分析表明模型拟合良好（χ²/df = 2.338，近似均方根误差 = 0.064，增值拟合指数 = 0.937，比较拟合指数 = 0.963，塔克-刘易斯指数 = 0.955，均方根残差 = 0.031）。QQPPI-C显示出极好地内部一致性（Cronbach's α = 0.939，Guttman's λ₄ = 0.940）、高内容效度（量表级内容效度指数 = 0.968）、足够的收敛效度以及不同性别间的测量不变性。
QQPPI-C是评估中国门诊医患互动质量的可靠且有效的工具。其使用有助于改善临床沟通以及开展以患者为中心的护理研究。
