ABSTRACT
Resumen: El objetivo del estudio es validar un Inventarlo que evalúa las dinámicas de corresponsabilidad y consenso familiar, donde la comunicación, la negociación de conflictos y las emociones son ejes centrales de la parentalidad positiva. 220 progenitores respondieron a un instrumento de 18 ítems. Se analizaron fiabilidad y validez de la prueba: consistencia interna, análisis diferencial de los ítems e invarianza de la medida. Se confirmaron 3 factores: imagen de matern idad/patern idad, comunicación emocional y consenso familiar;se mantuvo la invarianza configuracional pero no la métrica ni escalar. Género, nivel de estudios y ocupación laboral determinarían la competencia parental de ser padre y madre.Alternate :The goal of this study was the validation of an instrument to assess co-responsibility strategies and family agreement. Considering positive parenting as framework, communication, conflict negotiation and emotions constituted central axes. 220 parents completed an 18 Likert-item instrument. The reliability and validity of the instrument were analyzed: internal consistency, differential items functioning and the analysis of measurement invariance. A 3-factor structure was revealed: beliefs about motherhood and fatherhood, emotional communication and family agreement. Configurational invariance was maintained but not metric and scalar ones. Gender, educational level and labor occupation seemed to determine the parenting competence to be mother and father.
