Introduction: In this study, we developed a patient-reported instrument to measure shared decision-making (SDM) in rehabilitation medicine, and examined its reliability and validity in the field of physical therapy.
Methods: The SDM for rehabilitation (SDM-Reha) prototype was created from the elements of SDM determined to be necessary in the rehabilitation field by a previous study. This survey was conducted for patients undergoing physical therapy in the inpatient or outpatient setting and community.
Results: Data from 218 patients (mean 70.1 ± 13.3 years) were used for exploratory factor analysis and the SDM-Reha of 10 items with a one-dimensional nature was developed. The internal consistency of Cronbach's α of 0.94 and test-retest reliability of ICC (1,1) 0.93 were above acceptable thresholds. Concurrent validity was significantly correlated with the 9-item SDM questionnaire.
Conclusion: We developed the SDM-Reha as a new instrument based on the concept of SDM in the rehabilitation area. The SDM-Reha was confirmed to be reliable and valid for measuring SDM in rehabilitation practice.
