Cultural adaptation and validation of the Transcultural Self-Efficacy Tool for use with undergraduate nursing students in Spain

Abstract

BackgroundThe provision of culturally competent care helps reduce healthcare inequalities. There is a positive association between the cultural competence of nursing professionals and patient satisfaction, and also between nurses' self-efficacy and patients' adherence to treatment. While training in this respect is important, the self-assessment of skills should also be addressed. AimsTo produce a culturally-validated Spanish-language version of the Transcultural Self-Efficacy Tool (TSET) for use in undergraduate nursing studies, and to evaluate its implementation within the Spanish educational system. MethodsThis cultural adaptation and psychometric validation study was carried out with student nurses from two universities. International standards were followed for the translation and cultural adaptation of the questionnaire. All students completed the questionnaire twice, the second time 14 days after the first. Those who took the Transcultural Care course at the University of Málaga also completed the questionnaire a third time, after concluding this study subject. The reliability, discriminatory capacity, stability and sensitivity to change of the questionnaire were tested and confirmed, and a confirmatory factor analysis was performed. ResultsA total of 286 students took part in this study. Overall, the TSET obtained a reliability score of 0.978, according to Cronbach's alpha test. In relation to nationality of origin, the discriminatory capacity of the questionnaire was −1.067 (−1815 a −0,320) = 0.005. Stability, assessed at 14 days using the intraclass correlation coefficient, was 0.901 (0.873 a 0.923) <0.001. The before-after sensitivity to change for those who took the Transcultural Care course was 1.820 (1558 a 2083) <0.001. ConclusionsThis Spanish-language version of the TSET is culturally suitable for the educational context of undergraduate nursing students in Spain, and its psychometric validation was performed with satisfactory results.
