The objective of this study was to assess the validity and reliability of the Korean version of the patient-centered care (K-PCC) instrument for outpatients. The study was conducted due to the absence of a measurement tool specifically designed to evaluate patient-centered care for outpatients.
This study is a methodological study to verify the validity and reliability of the Korean version of Patient-Centered Care (K-PCC) to measure patient-centeredness for outpatients.
As a first step for the evaluation of the tool, the content validity was verified by expert panel. Then, a total of 400 outpatients were recruited, and construct validity was verified through confirmatory factor analysis (CFA) as the second step for the evaluation of the tool. The convergent and discriminant validity of the tool was verified by calculating the standardized factor loads, construct reliability (CR), and average variance extracted (AVE), and calculating the correlation square between the factors as the third and fourth steps for the evaluation of the tool. And as a fifth step for the evaluation of the tool, criterion validity was evaluated by comparing the correlation with the patient-centeredness measurement tool for inpatients (PEx-inpatient). In estimating reliability, internal consistency reliability coefficients were calculated.
The confirmatory factor analysis supported good fit for the Korean patient-centered care instrument (K-PCC), and the eight-factor structure was validated. The scale comprises 21 items across eight factors: patient preferences (4 items), physical comfort (2 items), coordination of care (2 items), continuity and transition (3 items), emotional support (2 items), access to medical care (3 items), information and education (2 items), and family and friends (3 items). The Cronbach's alphas ranging between 0.73 and 0.88.
The Korean patient-centered primary care instrument is a valid and reliable scale to measure patient-centered care for outpatients in the Korean medical environment.
本研究旨在评估门诊患者以患者为中心的护理（K-PCC）工具韩语版的有效性和可靠性。由于缺乏专门用于评估门诊患者以患者为中心护理的测量工具，故开展本研究。
本研究是一项方法学研究，旨在验证韩语版以患者为中心的护理（K-PCC）测量门诊患者以患者为中心程度的有效性和可靠性。
作为工具评估的第一步，通过专家小组验证内容效度。然后，招募了400名门诊患者，作为工具评估的第二步，通过验证性因子分析（CFA）验证结构效度。作为工具评估的第三步和第四步，通过计算标准化因子载荷、结构可靠性（CR）和平均提取方差（AVE），并计算因子之间的相关平方，验证工具的收敛效度和区分效度。作为工具评估的第五步，通过与住院患者以患者为中心的护理测量工具（PEx-住院患者）比较相关性来评估效标效度。在估计可靠性时，计算内部一致性可靠性系数。
验证性因子分析支持韩语以患者为中心的护理工具（K-PCC）具有良好的拟合度，并验证了八因子结构。该量表包括八个因子的21个项目：患者偏好（4项）、身体舒适度（2项）、护理协调（2项）、连续性和过渡（3项）、情感支持（2项）、医疗服务可及性（3项）、信息与教育（2项）以及家人和朋友（3项）。克朗巴哈系数在0.73至0.88之间。
韩语以患者为中心的初级护理工具是一种有效且可靠的量表，可用于测量韩国医疗环境中门诊患者以患者为中心的护理情况。
