Background Individualising the provided care is mandatory in nursing and is essential in clinical practice. Therefore, there is a need to develop accurate instruments to evaluate the quality of care. Moreover, there is no validated instrument to assess nurses’ views of individualised care in Spanish‐speaking countries. Aim To assess the construct validity and internal consistency of the Spanish version of the Individualised Care Scale‐Nurse. Methods A cross‐sectional study including 108 nursing professionals (40.84 ± 9.51 years old, 86.1% female) was used to validate the Spanish Individualised Care Scale‐Nurse version. A forward‐back translation method with an expert panel and a cross‐sectional study was used for transcultural adaptation and psychometric validation purposes. Psychometric properties of feasibility, reliability and validity were assessed. Construct validity was examined through a confirmatory factor analysis and fit indices of the overall model were computed. Internal consistency was explored through McDonald’s omega and Cronbach’s alpha coefficients among other correlation measures. Results The back‐translation concluded both Spanish and English Individualised Care Scale‐Nurse versions to be equivalent. The original structure of the Individualised Care Scale‐Nurse was verified in the Spanish version through the confirmatory factor analysis (factor loadings >0.3; acceptable fit indices: SRMR ≈ 0.08, CFI ≈ 0.9, RMSEA ≈ 0.09 after posteriori modifications). McDonald's omega exceeded 0.7 for both subscales and complete scales revealing an adequate internal consistency. Conclusions The Spanish version of the Individualised Care Scale‐Nurse has exhibited good properties of homogeneity and construct validity for its use in practice and research in health care systems.
