Quantitative Data Set.

The objective of this study is to evaluate changes in patient-centeredness attitudes, empathy, and emotional intelligence among nursing students trained with patients and caregivers as co-teachers. A mixed-methods embedded study was conducted. The quantitative strand consists of a quasi-experimental design, measuring third-year nursing students’ scores before and after an educational intervention, compared with first- and second-year students’ scores. Data were collected using three validated scales: the Patient-Practitioner Orientation Scale (PPOS-8-IT), Jefferson Scale of Empathy Health Professions Student (JSEHPS), and Self-Report Emotional Intelligence Test (SREIT). The qualitative strand explored student perceptions through focus group post-intervention. Quantitative and qualitative data were initially analyzed separately, then triangulated during interpretation. Results showed statistically significant improvements in scale scores post-intervention (n = 146). Three themes emerged from the qualitative analysis, aligning with quantitative findings. Patient-centeredness attitudes among students increased significantly after the intervention (PPOS-8-IT mean difference = 0.26, p
