Abstract
Objective: The objective of this study was to determine the psychometric proper-
ties of the 3-dimensional latent model of empathy on the Jefferson Scale of Physi-
cian Empathy instrument (version S), and to verify the existence of cutoff points
capable of differentiating empathy measures classified as: “high,” “medium,”
and “low” using data collected from observations of students from 11 dental fac-
ulties of 5 Central American and Caribbean countries (n = 3082) between 2015
and 2019.
Methods: This is an exploratory, “a posteriori,” and non-experimental study.
Factor structure and factor invariance by country and gender were analyzed.
Hierarchical cluster analysis and bifactorial analysis were applied, and the data
were normalized by cluster and by percentiles within them.
Results: Confirmatory factor analysis showed that the original model was repli-
cable and fit the data, while multigroup analysis allowed assuming an invariant
factor structure by country and by gender. There is reliability in the measurement
made by the scale and its dimensions.
