A systematic review of psychometric assessment of the Jefferson Scale of Empathy using the COSMIN Risk of Bias checklist.

The JSE demonstrates robust structural validity, internal consistency, and convergent validity. These measurement properties are generally well reported in the literature in studies of good methodological quality, and thus may be interpreted with relative confidence when used in empathy research. However, current evidence is limited for the properties of reliability, measurement error, and cross-cultural validity. Thus, a degree of caution should be considered in drawing conclusions when using the JSE with regard to these properties. It is recommended that future examinations of the JSE refer to the COSMIN guidelines to ensure complete and well-reported psychometric data are included.
