Validity and reliability of the Spanish version of the consultation and relational empathy measure in dental students (Sp-Dent-CARE): A cross-sectional study

Abstract

Introduction: An evaluation was made of the psychometric properties of a Spanish version of the Consultation and Relational Empathy Measure (CARE) to assess relational empathy in undergraduate dental students. In addition, the influence of demographic, socio-economic and consultation-related factors upon the degree of perceived empathy and overall satisfaction was studied.Materials and methods: A cross-sectional study was carried out in patients seen in the Oral Surgery Unit by fourth year dental students. Dentists, specialized translators and psychologists developed the translation of the questionnaire. After a pilot test, a convenience sample of patients was included. Construct validity was tested by factor analysis using principal component analysis with varimax rotation and Kaiser standardization, and internal consistency was assessed by Cronbach's α.Results: Two pilot tests were carried out with a panel of experts until the final version of the questionnaire was established. In the validation stage, 191 patients participated (92 men and 99 women), with a mean age of 52.5 ± 17 years. The mean score of the CARE measure was 47.2 ± 4.4, and 57.6% of the patients (n = 110) reported the maximum score on the questionnaire. The final version showed a 1-factor solution explaining 68.6% of the total variance, with excellent final internal consistency (α = 93.4%).Conclusion: The Spanish version of the CARE measure affords high reliability and validity in assessing relational empathy in dental students. Perceived empathy is related to overall satisfaction. Patient demographics and the number of visits do not influence perceived empathy.
