- Organizational commitment, psychometric qualities and invariance of the Meyer and Allen Questionnaire for Portuguese NursesPublication . Neves, Teresa; Graveto, João Manuel Garcia do Nascimento; Rodrigues, Victor; Maroco, J. P.; Parreira, PedroObjetivo: avaliar as qualidades psicométricas da versão portuguesa do Questionário de Comprometimento Organizacional, para o contexto da enfermagem, através de análise confirmatória e de invariância, visando a confiabilidade, consistência interna, validade de construto e a validade externa do instrumento. Método: procedeu-se à análise fatorial confirmatória da versão portuguesa do questionário, numa amostra de 850 enfermeiros, em contexto hospitalar. Complementou-se a análise com recurso à pesquisa de especificação. A qualidade de ajustamento foi avaliada através de diferentes índices. Estimou-se a confiabilidade, consistência interna e validade de construto. A invariância do modelo foi avaliada em duas subamostras, da amostra global, por forma a confirmar a validade externa da solução fatorial. Resultados: O modelo obtido após refinamento demonstrou bom ajustamento global (χ2/df=6,37; CFI=0,91; GFI=0,92; RMSEA=0,08; MECVI=0,62). A estrutura fatorial revelouse estável (λ:Δχ2(14)=18,31; p=0,193; Interceptos: Δχ2(14)=22,29; p=0,073; Covariância: Δχ2(3)=6,01; p=0,111; Resíduos: Δχ2(15)=22,44; p=0,097). Conclusão: o modelo simplificado do questionário revelou boa qualidade de ajustamento, apresentando uma solução fatorial estável. O instrumento revelou-se ajustado para monitorizar e avaliar o comprometimento organizacional dos enfermeiros portugueses.
- Practice environment scale of the nursing work index: portuguese version and psychometric propertiesPublication . Neves, Teresa; M. Parreira, Pedro; Graveto, João Manuel Garcia do Nascimento; Rodrigues, VL; Marôco, J. P.Aim: To assess the psychometric properties regarding the Portuguese version of the Practice Environment Scale of the Nursing Work Index. Background: The Practice Environment Scale of the Nursing Work Index is the most widely used measure for assessing the practice environment. A model with a higher number of factors appears to be more adequate to Portuguese settings. Method: A confirmatory factor analysis was performed to the Practice Environment Scale of the Nursing Work Index using a sample of 850 Portuguese nurses. Three models were tested: the original model, a seven-factor model and a higher-order model. An analysis of invariance was performed in two subsets to confirm the stability of the solution. Results: The seven-factor model fit better to the data than the original model. After refinement, this solution showed suitability and a stable factor structure. Reliability, convergent validity and discriminant validity were confirmed. A second-order factor solution also showed suitability. Conclusion: The seven-factor structure of the Practice Environment Scale of the Nursing Work Index showed a better goodness-of- fit to Portuguese settings than the original structure. The second-order factor solution allows an overall assessment of practice environments. Implications for Nursing Management: The Portuguese version of the Practice Environment Scale of the Nursing Work Index is a valuable tool for assessing Portuguese nursing practice environments. The seven-factor solution of the Practice Environment Scale of the Nursing Work Index showed high specificity.
