ABSTRACT
ABSTRACT Objective: to evaluate the psychometric qualities of the Portuguese version of the Organizational Commitment Questionnaire for the nursing context, through confirmatory analysis and invariance, aiming to evaluate the reliability, internal consistency, construct validity and external validity of the instrument. Method: confirmatory factor analysis of the Portuguese version of the questionnaire was carried out with a sample of 850 nurses, in hospital context. The analysis was complemented using specification search. Goodness of fit was evaluated through different indices. Reliability, internal consistency and construct validity were estimated. The invariance of the model was evaluated in two subsamples of the same sample, in order to confirm the external validity of the factorial solution. Results: the refined model demonstrated good overall fit (χ2/df=6.37; CFI=0.91; GFI=0.92; RMSEA=0.08; MECVI=0.62). The factorial structure was stable (λ:Δχ2(14)=18.31; p=0;193; Intercepts: Δχ2(14)=22.29; p=0.073; Covariance: Δχ2(3)=6.01; p=0.111; Residuals: Δχ2(15)=22.44; p=0.097). Conclusion: the simplified model of the questionnaire demonstrated adequate goodness of fit, representing a stable factorial solution. The instrument was fit to monitor and evaluate the organizational commitment of Portuguese nurses.
RESUMO Objetivo: 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 revelou-se 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.
RESUMEN Objetivo: evaluar las propiedades psicométricas de la versión portuguesa del Cuestionario de Compromiso Organizacional para el contexto de enfermería a través del análisis de confirmación e invarianza, para evaluar la fiabilidad, la consistencia interna, la validez de constructo y la validez externa del instrumento. Método: se procedió a un análisis factorial confirmatorio de la versión en portugués del cuestionario, con una muestra de 850 enfermeros en el ámbito hospitalario y se complementó el análisis con un recurso a la investigación de especificación. La calidad del ajuste se evaluó a través de diferentes índices. Se estimó la confiabilidad, la consistencia interna y la validez de constructo. La invarianza del modelo fue evaluada en dos sub-muestras de la muestra global, para confirmar la validez externa de la solución factorial. Resultados: el modelo obtenido tras el refinamiento demostró un buen ajuste global (χ2/df=6,37; CFI=0,91; GFI=0,92; RMSEA=0,08; MECVI=0,62). La estructura factorial reveló estable (λ:Δχ2(14)=18,31; p=0,193; Interceptos: Δχ2(14)=22,29; p=0,073; Covariancia: Δχ2(3)=6,01; p=0,111, Residuos: Δχ2(15)=22,44; p=0,097). Conclusión: el modelo simplificado del cuestionario demostró una buena calidad de ajuste, presentando una solución factorial estable. El instrumento resultó estar ajustado para monitorear y evaluar el compromiso de la organización de los enfermeros portugueses.

Compreender os vínculos com o trabalho e a organização empregadora, além de apontar as implicações para a estruturação do indivíduo, seu desenvolvimento e seu comportamento, estão entre os desafios nesta área do conhecimento. Este estudo investigou o comprometimento com a organização e o trabalho dos profissionais da Estratégia de Saúde da Família em uma Gerência Regional de Saúde em Santa Catarina entre 2005 e 2007. Objetivou identificar os padrões de comprometimento com a organização e o trabalho desenvolvido e explorar os fatores explicativos para os padrões de compromisso encontrados. A população, composta de médicos, enfermeiros, técnicos e auxiliares de enfermagem e odontólogos, totalizou 347 profissionais, com amostra de 252 sujeitos, 72,62% da população. O instrumento englobou variáveis preditoras dos vínculos, além das medidas destes construtos. Os dados processados e analisados possibilitaram distinguir seis padrões: duplamente comprometidos e descomprometidos, comprometidos unilateralmente com a organização e o trabalho, descomprometidos com a organização e o trabalho. Como variáveis explicativas, identificaram-se as organizacionais, como as políticas de recursos humanos e as do trabalho como feedback, expectativas alcançadas, variedade de habilidades, dentre outras, variando segundo os padrões identificados. Foi evidenciada a precarização do trabalho pela associação entre o vínculo empregatício e a díade de comprometimento.
Understanding the relations with the work and employing organization besides indicating the implications for the structure formation, development and behavior of the individual are among the challenges in this field of knowledge. This study investigated the commitment with the organization and work (commitment dyad) of professionals from the family health strategy at a regional health management in santa catarina between 2005 and 2007. It aimed at identifying the commitment patterns with the organization and developed work and exploring the explicable factors for the commitment patterns found. the population comprised physicians, nurses, technicians and nursing assistants and dentists totaling 347 professionals and a sampling of 252 subjects, representing 72,62% of the population. The instrument comprised variables featuring the relations besides the measures of these constructs. The processed and analyzed data evidenced six patterns: doubly committed and non-committed, unilaterally committed with the organization and work, non-committed with the organization and work. The identified explicable variables were the organizational ones like human resources policies and the work ones like feedback, met expectancies, variety of abilities among others varying according to the identified patterns. the precariousness of the work was evidenced due to the association between the employment relation and the commitment dyad.
