RESUMEN
BACKGROUND: Interprofessional education offers students from different disciplines the opportunity to share learning experiences. PURPOSE: To develop and validate a Spanish version of the KidSIM Team Performance Scale, thus providing a tool for assessing the team performance of undergraduate health professionals in our cultural context. METHOD: Descriptive observational study consisting of two phases: a) translation and adaptation of the original instrument, b) validation of the Spanish version. RESULTS: The Spanish version comprises 11 items and is linguistically and conceptually equivalent to the original scale. Factor analysis yielded a model comprising three factors: roles and leadership capacity, communication, and use of resources. Internal consistency was good (Cronbach's alpha = 0.85), while inter-observer agreement was moderate (Cohen's kappa = 0.58). The RMSEA fit index was acceptable (0.0801 [0.0618-0.115]). CONCLUSION: The Spanish version of the KidSIM Team Performance Scale is a valid and reliable tool for assessing simulated teamwork among undergraduate health professionals.
