Regarding the first objective, our findings confirmed differences in empathy measurements in nursing students by sex, nursing school and the interaction of both. These findings, regarding sex, are in consonance with previous studies performed in other cultural settings in nursing students and other non-medicine healthcare students [44–46]. On the other hand, differences observed by nursing school (public vs. private) suggest that, in the absence of a targeted training in empathy, the social environment surrounding the university acquires an important role of influence in the development of empathy in nursing students. This finding brings evidence supporting the idea, proposed by Susanne Täuber, that social environments influence human relationships and social interactions [47]. Elitism, social stereotypes and racial bias, appear as possible manners of this influence. Elitism: In Peru, similarly to other countries, studying in a private university implies an important economic investment for students and their families, not always accessible for everyone. Elitism among students enrolled in these institutions is a social consequence derived from it. In the US, this elitism has been characterized as an influencing factor in the lack of altruist and lower scores in empathy measures in American medical students enrolled in high-ranked institutions [48,49]. Social stereotypes and racial bias: Social influence can be also strengthening by the effect of cultural and racial stereotypes that are still dominant in the Peruvian society [50]. Indeed, studies in social psychology and neurosciences have revealed that empathic responses may be reduced by social stereotypes and racial bias [51,52]. Findings observed from the comparison analysis of the scores of the Satisfaction with Life Scale by university groups may reinforce this interpretation.
The second objective was to determine the type of association between empathy and the other variables measured. Empathy showed a positive correlation with measures of teamwork and lifelong learning. These findings bring evidence supporting the theory that these three competences are specific elements of a common construct: professionalism [53]. Furthermore, this finding is in consonance with others reported in Mexico, where a positive association between empathy and teamwork measures was observed in students of nursing [24]. On the contrary, empathy showed an inverse correlation with loneliness measures and age. These findings, in the case of loneliness, are in consonance with others recently reported in Chilean nurses [2] and Spanish nursing students [33]. Age, but not academic achievement, showed an inverse association with empathy indicating that this association was due to the students’ age and not by the semester in which the student was enrolled. Taking this into account, this association may be consequence of the social environment, previously described. In this sense, it is possible that older students become less idealistic and carry more social prejudgments than their younger peers, and this difference is reflected in a lower score in empathy.
Finally, the third objective was to characterize variables as predictors of empathy’s measurements. A linear regression analysis confirmed preliminary findings indicating that teamwork, sex (being a female student) and studying in a public nursing school, are positive predictors of empathy. On the contrary, age, loneliness and subjective well-being appeared as negative predictors of empathy. It is not surprising that subjective well-being plays a negative role of influence in the development of empathy after taking into consideration the differences observed when private and public university groups were compared. In the absence of a targeted training on empathy, it is possible that students enrolled in private universities have less personal resources for empathizing with poor patients. On the contrary, students from public universities probably have more personal resources at the moment to understand and communicate with patients who have to straggling with economic issues related to their treatments.
Limitations and strengths
To appreciate the findings of this study, some limitations require consideration. First, the design of the study was a cross-sectional self-reporting questionnaire. Self-reporting could lead to response bias or social-desirability bias. Second, analyses are based upon a convenient sample of nursing students from one Peruvian region. And third, loneliness, one of the variables measured, is described as a multiple dimensional concept that can be analysed as a global construct or as separate domains. However, inference analysis performed in this study allowed only a global characterization of loneliness since the models did not fit with all necessary conditions when using separate domains.
On the contrary, the strengths of this study are: the large sample size, which provides great statistical power to analyse the current level of knowledge and elements measured; the good psychometric properties of the instruments; and the fact that Cusco city has a significant relevance in other cultural contexts, due to its multicultural and multilingual social structure.
Implications
Empathy is a core competence in nursing. To understand the main factors influencing empathy, which are not directly related with formal curricula, is highly important for educators. Findings observed in this study bring valuable information of non-academic elements that are influencing the empathic ability of nursing students. This knowledge acquires more relevance under current circumstances of the pandemic since many nursing schools are adapting their curricula to e-learning or blended methodologies. This drastic change has important implications in the training of empathic abilities that require intensive social contact. Staying at home privileges the influence that other aspects, associated to the social environments (such as family) and personal resources, have in the early development of this ability. Future research should explore nursing students’ behaviour regarding communication and understanding abilities associated with empathy after the pandemic is over in order to determine suitable methodological strategies for its enhancement in safety conditions.
