Background:
Empathy and effective communication are core competencies in emergency care, yet structured training explicitly targeting these skills is uncommon in undergraduate curricula. We evaluated whether a Nonviolent Communication (NVC) curriculum, a structured framework centered on observation, feelings, needs, and requests, improves empathy and observed communication performance in undergraduate medical students.
Methods:
We conducted a single-center, parallel-group randomized controlled educational intervention among fourth-year medical students at Nantong University (2024-2025). Participants were randomized to an NVC-based training program (n = 100) or a time- and dose-matched standard curriculum control (active control, n = 98). Empathy was measured using the Jefferson Scale of Physician Empathy (JSPE; primary outcome), and observed communication performance was assessed using the simplified Calgary-Cambridge-Guided communication checklist (SCCG; secondary outcome) in OSCE-style role-play encounters. Primary analyses used linear mixed-effects models with a group-by-time interaction.
Results:
All 198 randomized students completed baseline and post-course assessments. In the primary mixed-effects models, NVC training produced a significantly larger increase in JSPE than control (group-by-time interaction β = 16.95; 95% CI, 15.40-18.50; P < 0.001) and a significantly larger improvement in SCCG performance (β = 4.44; 95% CI, 3.41-5.47; P < 0.001).
Conclusions:
A structured, practice-oriented NVC curriculum produced greater short-term gains in self-reported empathy and observed communication performance than the active control. Multicenter trials with longer follow-up are needed to assess durability and generalizability.
Trial Registration:
Not prospectively registered.
