Adaptação Transcultural do Model For Understanding Success In Quality (MUSIQ) para o português do Brasil

Abstract

Introduction: Projects aimed at improving healthcare quality do not always succeed due to contextual difficulties. However, Brazil currently lacks adapted instruments to analyze the context of healthcare institutions, adjust project interventions to that context or interpret their outcomes. Objective: This study aims to conduct the transcultural adaptation of the Model For Understanding Success In Quality - MUSIQ Calculator questionnaire into Brazilian Portuguese. Method: The adaptation process followed five stages: 1) Initial translation of the MUSIQ Calculator; 2) Synthesis of translations; 3) Back-translation; 4) Expert review by Brazilian experts; and 5) Pretesting. "During stage 4, the questionnaire's definitions, terms, and items were analyzed concerning: a) semantic equivalence, b) idiomatic equivalence, and c) cultural equivalence. This analysis utilized a Likert scale, allowing for the calculation of the Transcultural Equivalence and Adaptation Index (TEAI), with a cutoff point >0.8. The pre-test was carried out with 23 professionals from six maternity hospitals within the Unified Health System (SUS) to assess feasibility and provide descriptive statistics. Results: The translated and culturally adapted questionnaire was named the Calculadora MUSIQ - Modelo para Entender o Sucesso em Qualidade. It consists of 35 items grouped into six dimensions. All items achieved a TEAI above 0.8. The average administration time was 20 minutes (range: 8–60 minutes). Conclusion: This Portuguese questionnaire addresses a significant gap in health services research in Brazil, as well as in healthcare management practice. Future health services research improvement projects can utilize the questionnaire before, during, and after interventions to enhance their effectiveness and broaden the impact of quality improvement initiatives
