Objective. This study aimed to provide further validity evidence for the Kiersma-Chen Empathy Scale (KCES) by analyzing data collected from multiple administrations of the scale and conducting cognitive interviews of students in pharmacy and nursing programs to identify needed revisions.Methods. De-identified data from previous administrations of the KCES were used to evaluate the scale. Evidence of response process was enhanced through cognitive interviews with 20 pre-pharmacy and pharmacy students at Cedarville University. After survey revisions, the cognitive interview process was repeated with 10 University of Wyoming nursing students.Results. Based on psychometric data and cognitive interviews, the KCES was revised as follows: key components of cognitive and affective empathy were retained, scaling was changed to reflect necessity and empathy ability, negatively worded items were removed, and the single scale was converted into two parallel subscales.Conclusion. This study used data from thousands of geographically and professionally diverse samples. Based on potential problems identified in quantitative analyses, cognitive interviews with nursing and pharmacy students were conducted, and modifications to the KCES were made. Further psychometric validation is needed regarding the KCES-R.
