Adaptação Portuguesa do Questionário de Coparentalidade: Análise Fatorial Confirmatória e Estudos de Validade e Fiabilidade.

The purpose of this study was to adapt and examine the psychometric properties, validity and reliability of the Portuguese version of the Coparenting Questionnaire (Margolin, Gordis, & John, 2001). The Coparenting Questionnaire includes 14 itens organized in 3 subscales: Cooperation, Triangulation and Conflict. Data were collected from 1,133 participants (530 fathers and 603 mothers) with preadolescent children. Factorial validity was tested through confirmatory factor analysis. The results replicated the original three-factor structure: Cooperation, Triangulation and Conflict. Confirmatory factor analysis indicated a good fit of the model for fathers (CFI = .94, RMSEA = .06, SRMR = .05) and for mothers (CFI = .96, RMSEA = .06, SRMR = .05). The instrument presents Cronbach's alpha coefficients between acceptable and good (.71 < a < .88) as well as adequate values for the convergent and discriminant validity. These results support the validity of the coparenting construct and the Portuguese version of the Coparenting Questionnaire as a valid measure. [ABSTRACT FROM AUTHOR]
