Objetivos: Este estudo teve como objetivo adaptar, validar e analisar a fiabilidade do Medical Office Survey on Patient Safety Culture (MOSPSC) para os cuidados de medicina dentária em Portugal. Métodos: A versão portuguesa do MOSPSC, da Agency for Healthcare Research and Quality (AHRQ), foi adaptada para os cuidados de medicina dentária em Portugal. Seis especialistas foram responsáveis pela análise semântica e validade de conteúdo. Para a análise de fiabilidade foi calculado o alfa de Cronbach e a average inter-item correlation (AIIC). A análise fatorial confirmatória (AFC) avaliou a qualidade do ajustamento do modelo associado ao modelo teórico proposto pela AHRQ. Os testes de ajustamento utilizados foram o quociente entre o qui-quadrado e o número de graus de liberdade (χ2/df), o índice goodness-of-fit (GFI), o índice comparative fit (CFI), o índice Tucker-Lewis (TLI), o parsimony GFI e o índice root mean square error of approximation (RMSEA). Resultados: Na amostra inicial procedeu-se à análise de valores omissos, resultando numa amostra final de 143 participantes. O modelo proposto pela AFC correspondeu à junção de dois pares de dimensões (dimensões “comunicação acerca do erro” e “abertura na comunicação”; “processos e padronização” e “pressão e ritmo de trabalho”). O modelo proposto obteve uma boa consistência global (alfa de Cronbach α=0,93; AIIC=0,27) e um ajustamento global moderado face à amostra em estudo (χ2/df=5,63; GFI=0,90; CFI=0,90; TLI=0,88; PGFI=0,67; RMSEA=0,18; p<0,001; IC de 90% RMSEA [0,175;0,186]). Conclusões: A estrutura do modelo proposto resultou em oito dimensões, que obtiveram uma boa fiabilidade e uma validade de constructo moderada.
ABSTRACT - Objectives: The purpose of this study was to adapt, validate, and analyze the reliability of the Medical Office Survey on Patient Safety Culture (MOSPSC) for Portuguese dental care. Methods: The Portuguese version of the MOSPSC of the Agency for Healthcare Research and Quality (AHRQ) was adapted for Portuguese dental care. Six specialists conducted the content validity and semantic analysis. The reliability analysis was performed using Cronbach’s alpha and average inter-item correlation (AIIC). Confirmatory factor analysis (CFA) was conducted to assess the fit quality of the model associated with the theoretical model proposed by the AHRQ. The following goodness-of-fit indexes were used: the quotient between chisquare and the number of degrees of freedom (χ2/df), the goodness-of-fit index (GFI), the comparative fit index (CFI), the Tucker-Lewis index (TLI), Parsimony GFI, and the root mean square error of approximation index (RMSEA). Results: The initial sample (n=237) was subjected to an analysis of missing values, resulting in a final sample of 143 participants. The model proposed by the CFA corresponded to the joining of two pairs of dimensions (“communication about error” and “communication openness” dimensions; “office processes and standardization” and “work pressure and pace” dimensions). The proposed model obtained good overall consistency (Cronbach’s α=0.93; AIIC=0.27) and moderate overall fit considering the study sample (χ2/df=5.63; GFI=0.90; CFI=0.90; TLI=0.88; PGFI=0.67; RMSEA=0.18; p<0.001; 90% CI RMSEA [0.175;0.186]). Conclusions: The proposed model structure resulted in eight dimensions, which achieved good reliability and moderate construct validity.
