Abstract
Background and Objectives: This review used the recent COnsensus-based Standards for the selection of health Measurement INstruments (COSMIN) rating system, which gives the reader the ability to find appropriate instruments in a simple way. Shared decision-making (SDM) is part of health professionals', nurses', and patients' interaction about fundamental and special nursing care issues. The objective of this study was to critically appraise instruments that measure SDM in health care-related decisions according to the COSMIN criteria.
Methods: This review was reported in accordance with the PRISMA (Preferred Reporting Items for Systematic reviews and Meta-Analyses) guideline. A thorough search identified SMD measures via PubMed, Cochrane Library, MEDLINE, EBSCO Host, Ovid journals, SAGE journals, and Google Scholar search engine through November 2018 and updated on March 24, 2019. A rating system with "very good," "adequate," "doubtful," or "inadequate" for COSMIN was used.
Results: The 17 instruments reported in this review are varied in the measured perspectives; observer-based viewpoint, patient questionnaires, provider questionnaires, and physician questionnaires, or even mixed perspectives. Only one instrument (OPTION 12 Scale) received an excellent rating across all 5 COSMIN validity rating sections in content, structural, and criterion validity.
Conclusion: Most of the instruments scored poorly on the COSMIN checklist. Despite the vast number of instruments measuring SDM, researchers must undertake critical appraisal before selecting an acceptable instrument that meets the specific research goal, as well as the quality requirements.
