Context: Assessing primary care is a matter. Although a number of measures have been developed, they do not cover a broad range of primary care. Because patient experience measures, in nature, have focused on the patient experience as a consumer such as care delivery or receipt of services, they do not include much of physicians’ and health care payer’s perspectives. A measure grounded in the combined experience of patients, clinicians and payers is necessary to assess the whole of primary care. For the purpose, Etz et all developed Person-Centered Primary Care Measure (PCPCM) including 11 questions to assess 11 domains, accessibility, advocacy, community context, comprehensiveness, continuity, coordination, family context, goal-oriented care, health promotion, integration, and relationship. The measure has been translated into more than 25 languages. The study is to develop the Japanese version of the PCPCM.

Objective: This study aims to develop and validate the Japanese version of the PCPCM. The measure will enable Japanese patients, physicians and payers to assess the quality of the whole of primary care in Japan and to compare it with other countries.

Study Design: a cross-sectional survey

Setting: A basic resident register in Japan.

Population studied: Randomly-selected 1,000 participants will be sent a questionnaire.

Outcome Measures: This study will exam internal consistency, exploratory factor analysis, and criterion related validity. Internal consistency will be assessed by Cronbach’s a. Moreover, inter-rater reliability will be esamined by intraclass correlation coefficients. Factor analysis will be employed o explore the structure of the PCPCM items and examine its construct validity. Also, criterion related validity will be assessed by using a correlation between the total score of the Japanese version of the PCPCM and the total score of the Japanese version of Primary Care Assessment Tool, which is a questionnaire validated and widely used to assess patient experience in Japan.

Results: Translation into Japanese and back translation into English by the research team has already finished. Now, the authors of the original PCPCPM is checking the back translation. After that, cognitive debriefing by the patients in the Japanese primary care setting, test for reliability and validity will be conducted. The results will be useful to assess the whole of the Japanese primary care and an important step to improve it.

Great to read the process of how to validate the tool which was developed in other languages. It is way beyond my ability to understand but I am particularly curious about the validity of the survey in Japanese primary care! great work!
