Tradução, adaptação transcultural e análise das propriedades de medida da Lucerne ICF Based Multidisciplinary Observation Scale (LIMOS) - escala de uso multiprofissional baseada na CIF

Abstract

Introduction: New instruments are needed to measure functionality and produce health indicators. The Lucerne rehabilitation center developed a standardized instrument, easy to apply in clinical practice, called the Lucerne ICF Based Multidisciplinary Observation Scale (LIMOS). However, the use of this instrument is not yet available in Brazil. Objective: to translate and carry out the cross- cultural adaptation of the LIMOS scale to be used in Brazil and verify reproducibility, validity and accuracy. Methods: The translation and cross- cultural adaptation process consisted of the phases described in COSMIN. 83 adults who had had a stroke participated in the study. Reproducibility, Standard Measurement Error, Minimum Detectable Change were analyzed. Internal consistency, external validation and accuracy, considering risk α=0.05. Results: The LIMOS-Brazil instrument demonstrated adequate semantic equivalence after adaptations. The LIMOS total scale values presented an internal consistency of 0.89, good intra- and inter-rater reproducibility (ICC2.1 = 0.97; CI95%=0.94-0.98 and ICC2.1 = 0.85; CI95% =0.73-0.91, respectively). Positive and strong convergent validity with the MIF (rho=0.85; p<0.01) and accuracy to indicate independence in functionality with a cut-off score of 183 points (sensitivity 85.2% and specificity 88.6%). Conclusion: The preliminary analysis showed stability of the test-retest data in the total result and in most subscales, good external validity and accuracy for people who had a stroke.
