Validity and reliability of the 2-item version compared with the 10-item version of the Japanese consultation and relational empathy (CARE) measure: primary analysis of a cross-sectional survey Open
Although the high number of patients required per doctor to reliably discriminate between doctors' empathy may limit its feasibility in practice and careful interpretation is warranted, the Japanese 2-item version has high validity and int…
