Validity evidence of the Brazilian version of the Assessment Interprofessional Collaborative Leadership Scale

to seek evidence of validity of the Assessment Interprofessional Collaborative Leadership Scale for Brazilians, in Portuguese, and to analyze evidence of content, response process and internal structure.

psychometric evaluation study, with translation, back-translation, and evaluation by a committee of experts regarding linguistic and content equivalence. The pre-test was carried out with 40 participants and, subsequently, the final version was applied to 318 health workers. Exploratory factor analysis and reliability testing were performed using Cronbach's alpha and McDonald's omega.

in the content validation, four items presented scores below the critical value. Of the participants, the majority were nurses (81%) and physiotherapists (10%), and were female (79%). The factorability obtained was Kaiser-Meyer-Olkin = 0.94 and Bartlett's sphericity = 2991.4 with p < 0.05. Parallel analysis indicated a one-dimensional model, with variance explained by 63.71%. The model's adequacy indices showed satisfactory levels. And adequate reliability indices (Cronbach's alpha = 0.97 and McDonald's omega = 0.97).

the Interprofessional Collaborative Leadership Assessment Scale, with a unidimensional structure and 28 items, presented good evidence of content validity, response process and internal structure, considered adequate to measure interprofessional collaborative leadership.
