- Abstract
Objective: to validate the Portuguese version of the Leg Ulcer Measurement Tool regarding construct and reliability. Method: this is a methodological research study. Data collection was conducted between January and July 2019. A total of 105 participants were included for construct validation and internal consistency and, of these, 50 were selected for intra-observer stability. For the analysis of construct validity, factor analysis was performed; for internal consistency, Cronbach's alpha coefficient was calculated, and for stability, the intraclass correlation coefficient. Results: A total of 12items were confirmed for the Brazilian reality, meeting all the theoretical requirements of the factor analysis model. As for the internal consistency (reliability) analysis, the Cronbach's alpha coefficient values (α=0.711) showed that the set of items that make up the scale measures the same characteristics and presents internal consistency. In the global stability analysis (ICC=0.823), the Leg Ulcer Measurement Tool test and retest scores presented good agreement, showing that the adapted scale is stable. Conclusion: the Leg Ulcer Measurement Tool scale adapted to the Portuguese language contains 12 items, with scores varying from 0 to 4 and, thus, produces a score from 0 to 48 points. It presents construct validity analyzed by means of factor analysis and reliability in terms of internal consistency and stability.
