Cross-cultural adaptation and validation of the Jefferson Scale of Attitudes Toward Physician-Nurse Collaboration (JSATPNC) in the Spanish context

Interprofessional collaboration between physicians and nurses is a critical aspect of healthcare. The Jefferson Scale of Attitudes Toward Physician-Nurse Collaboration (JSATPNC) is the most widely used instrument for assessing attitudes toward such collaboration. However, this scale has not been validated in Spain. This study aimed to translate and adapt the JSATPNC to the Spanish context and evaluate its psychometric properties. Following its translation and adaptation, the scale was administered to a sample of 205 primary care physicians and nurses. Construct validity was assessed using confirmatory factor analysis (CFA) and Rasch analysis. The CFA based on the original four-dimensional model demonstrated good fit indices (RMSEA = 0.053, RMSR = 0.037, CFI = 0.974, NNFI = 0.947) and suggested the possibility of a unidimensional model (MIREAL = 0.211). Rasch analysis indicated good fit, except for items 1 and 5. Internal consistency reliability was acceptable (Omega = 0.801 [95% CI: 0.734–0.823]). The Spanish version of the JSATPNC (JSATPNC-e) exhibits adequate psychometric properties in terms of construct validity and internal consistency reliability. This study provides the Spanish-speaking population with an adaptation of the most widely used instrument for evaluating interprofessional collaboration between nurses and physicians.
