Although primary care (PC) is an indispensable part of the health system, measuring its quality is challenging. A recent measure of PC, Person-Centered Primary Care Measure (PCPCM), covers 11 important domains of PC and has been translated into 28 languages. This study aimed to develop a Japanese version of the PCPCM and assess its reliability and validity.
We employed a cross-sectional mail survey to examine the reliability and content, structure, criterion-related, and convergent validity of the Japanese version of the PCPCM. This study targeted 1000 potential participants aged 20-74 years, selected by simple random sampling in an urban area in Japan. We examined internal consistency, confirmatory factor analysis, correlation between the Japanese version of the Primary Care Assessment Tool-Short Form (JPCAT-SF), and the association between the PCPCM score and influenza vaccine uptake.
A total of 417 individuals responded to the survey (response rate = 41.7%), and we used the data of 244 participants who had the usual source of care to assess the reliability and validity of the PCPCM. Confirmatory factor analysis demonstrated sufficient structural validity of the original one-factor structure. The overall Cronbach's alpha was 0.94. The Spearman correlation coefficient between PCPCM and JPCAT-SF was 0.60. Influenza vaccine uptake was not significantly associated with total PCPCM score.
The study showed that the Japanese version of the PCPCM has sufficient internal consistency reliability and structural- and criterion-related validity. The measure can be used to compare the quality of primary care in Japan and other countries.
尽管初级保健（PC）是卫生系统不可或缺的一部分，但衡量其质量具有挑战性。最近的一项 PC 衡量标准，以患者为中心的初级保健衡量标准（PCPCM），涵盖了 11 个重要的 PC 领域，并已被翻译成 28 种语言。本研究旨在开发 PCPCM 的日文版本，并评估其信度和效度。
我们采用横断面邮件调查来检验 PCPCM 日文版的信度和内容、结构、效标关联和收敛效度。本研究以日本一个城市地区通过简单随机抽样选择的 1000 名 20-74 岁的潜在参与者为目标。我们检验了内部一致性、验证性因子分析、与初级保健评估工具-短表（JPCAT-SF）的相关性以及 PCPCM 评分与流感疫苗接种率之间的关联。
共有 417 人对调查做出回应（回应率=41.7%），我们使用了 244 名有常规医疗服务来源的参与者的数据来评估 PCPCM 的信度和效度。验证性因子分析表明原始单因素结构具有足够的结构效度。总体 Cronbach's alpha 为 0.94。PCPCM 与 JPCAT-SF 之间的 Spearman 相关系数为 0.60。流感疫苗接种率与总 PCPCM 评分无显著相关性。
该研究表明，PCPCM 的日文版本具有足够的内部一致性信度以及结构和效标关联效度。该衡量标准可用于比较日本和其他国家的初级保健质量。
