{ "abstract": "Background: Shared decision making (SDM) integrates the expertise of healthcare providers with the values and preferences of patients. The Multifocal Approach to Sharing in Shared Decision-Making (MAPPIN’SDM) based on a six-step SDM model, has shown robust reliability and validity in diverse settings. This study aimed to validate the Korean version (K-MAPPIN’SDM) and assess its applicability in Korean clinical practice. Methods: The K-MAPPIN’SDM was developed through a translation and cultural adaptation process including forward translation, synthesis, blind back translation, semantic equivalence review, and multidisciplinary evaluation for accuracy in the Korean context. The instrument was piloted with six physicians and 288 patients involved in SDM. For construct validity, exploratory factor analysis (EFA) and confirmatory factor analysis (CFA) were conducted. Psychometric evaluation included Pearson’s correlation, Guttman split-half coefficient, and Cronbach’s alpha. Criterion validity was assessed using the 9-Item Shared Decision-Making Questionnaire (SDM-Q-9), SDM-Q-Doc, and Communication Assessment Tool (CAT). Results: The final K-MAPPIN’SDM was successfully developed through a scientifically rigorous and culturally sensitive translation and validation process. EFA and CFA supported a one-factor model for both versions of K-MAPPIN’SDM, though model fit was better for the patient version. Internal consistency of the K-MAPPIN’SDM was high (Cronbach’s α = 0.94 for healthcare provider version; 0.87 for patient version). Guttman coefficients were 0.90 and 0.73, respectively. The provider version correlated strongly with SDM-Q-Doc (r = 0.88, p < .001); the patient version correlated with SDM-Q-9 (r = 0.58, p < 0.001) and CAT (r = 0.47, p < .001). Conclusions: The K-MAPPIN’SDM is a psychometrically sound tool for assessing SDM. This scale has the potential to be widely used to assess SDM in Korea. K-MAPPIN’SDM can serve as a tool to assess current state of SDM implementation from diverse perspectives in Korea and provide framework for training healthcare providers in SDM practices.", "abstract_shown": true, "affiliations": [ "College of Nursing, Seoul National University, Seoul, Republic of Korea", "Research Institute of Nursing Science, Seoul National University, Seoul, Republic of Korea", "College of Nursing, Chungbuk National University, Cheongju, Republic of Korea", "Research Institute of Nursing Science, Chungbuk National University, Cheongju, Republic of Korea", "Department of Medical Humanities and Ethics, College of Medicine, Hanyang University, Seoul, Republic of Korea", "College of Nursing, Jeju National University, Jeju, Republic of Korea", "Health and Nursing Research Institute, Jeju National University, Jeju, Republic of Korea" ], "article_type": "Research Article", "arxiv": null, "author_total": 7, "authors": [ { "affs": [ 0 ], "name": "Heeseung Choi" }, { "affs": [ 1 ], "name": "Jongeun Lee" }, { "affs": [ 2 ], "name": "Sang-Ho Yoo" }, { "affs": [ 3 ], "name": "Junggeun Ahn" }, { "affs": [ 4 ], "name": "Youngeun Park" }, { "affs": [ 5 ], "name": "Hannah Kim" }, { "affs": [ 6 ], "name": "Jürgen Kasper" } ], "bibtex": "https://research.draconitic.com/paper/652pktvcqe6aw.bib", "cited_by": 0, "doi": "10.1371/journal.pone.0347018", "fulltext_url": null, "id": "652pktvcqe6aw", "issns": [ "1932-6203" ], "landing_url": "https://doi.org/10.1371/journal.pone.0347018", "language": null, "licence": "CC-BY-4.0", "licence_label": "CC BY 4.0", "licence_source": "journal", "licence_url": "https://creativecommons.org/licenses/by/4.0/", "metadata_licence": null, "native_subjects": [ [ "openalex", "3600|Patient-Provider Communication in Healthcare" ], [ "plos", "/Biology and life sciences/Neuroscience/Cognitive science/Cognition/Decision making" ], [ "plos", "/Biology and life sciences/Neuroscience/Cognitive science/Cognitive psychology/Decision making" ], [ "plos", "/Biology and life sciences/Psychology/Cognitive psychology/Decision making" ], [ "plos", "/Biology and life sciences/Psychology/Psychometrics" ], [ "plos", "/Medicine and health sciences/Health care/Health care providers" ], [ "plos", "/Medicine and health sciences/Health care/Health care providers/Allied health care professionals" ], [ "plos", "/Medicine and health sciences/Health care/Health care providers/Physicians" ], [ "plos", "/People and places/Geographical locations/Asia/Korea" ], [ "plos", "/People and places/Population groupings/Ethnicities/Asian people/Korean people" ], [ "plos", "/People and places/Population groupings/Professions/Medical personnel/Physicians" ], [ "plos", "/Physical sciences/Mathematics/Statistics/Statistical methods/Factor analysis" ], [ "plos", "/Research and analysis methods/Mathematical and statistical techniques/Statistical methods/Factor analysis" ], [ "plos", "/Social sciences/Psychology/Cognitive psychology/Decision making" ], [ "plos", "/Social sciences/Psychology/Psychometrics" ] ], "openalex": "W7207643563", "pdf_url": null, "pmcid": null, "pmid": null, "published": "2026-09-03", "publisher": "Public Library of Science", "ris": "https://research.draconitic.com/paper/652pktvcqe6aw.ris", "sources": [ { "first_seen": "2026-10-30T12:17:56Z", "native_id": "10.1371/journal.pone.0347018", "source": "plos", "url": "https://doi.org/10.1371/journal.pone.0347018" } ], "subjects": [ { "field": "biology", "origin": "plos:neuroscience", "subfield": "neuroscience" }, { "field": "mathematics", "origin": "plos:statistical methods", "subfield": "statistics" } ], "title": "Reliability and validity of the Korean version of MAPPIN’SDM for patients and healthcare providers", "title_text": "Reliability and validity of the Korean version of MAPPIN’SDM for patients and healthcare providers", "type": "peer-reviewed", "updated_at": "2026-10-30T12:17:56Z", "url": "https://research.draconitic.com/paper/652pktvcqe6aw", "venue": "PLOS One", "versions": [] }
