Reliability and validity of the lasater clinical judgment rubric – Brazilian version

Abstract

Objective: To evaluate the reliability and validity of the Lasater Clinical Judgment Rubric - Brazilian Version in a sample of nursing students. Methods: Methodological design study conducted at a public institution of higher education in the southeast region of Brazil. Preliminarily, was analyzed the clarity of behaviors described by eight students in each level of the 11 dimensions of the instrument. Next, was collection of data on the evaluation of psychometric properties with self-application by 179 students. Participants were grouped in junior (1st and 2nd terms n=115) and senior (3rd and 4th terms n=64) students. The following psychometric properties were analyzed: discriminant validity, reliability and dimensionality. Results: Through the Brazilian version of the rubric were differentiated the two groups of students (p-value <0.05) in the 11 dimensions evaluated. Stability was verified by test-retest (Intraclass Correlation Coefficient – ICC: 0.88). Internal consistency was obtained for the global instrument (Cronbach’s alpha: 0.899) and for phases of Noticing (α=0.75), Interpreting (α=0.64), Responding (α=0.78) and Reflecting (α=0.63). Dimensionality validity by confirmatory factorial analysis (CFA) obtained results of composite reliability (CR) above 0.7, and average variance extracted (AVE) higher than 0.5 in all phases. The discriminant validity of the factorial model by the Fornell-Larcker criterion and cross loadings confirmed the theoretical structure of the rubric original version. Conclusion: The evaluation of the psychometric properties of the Brazilian version of the rubric showed evidence of reliability and construct validity of the instrument for measuring the development of nursing students’ clinical judgment.
