Psychometric Properties of the Coparenting Relationship Scale in Ecuadorian Parents

Background: The Coparenting Relationship Scale is a robust tool for assessing the quality of coparenting, with evidence of validity and reliability tested in diverse cultural and population contexts. Objective: The aim of this study was to evaluate the psychometric properties of the Coparenting Relationship Scale in Ecuadorian fathers and mothers in order to determine its validity and reliability in the specific cultural context of Ecuador. Method: An instrumental study was carried out by analyzing psychometric properties. The sample consisted of 867 participants from the province of Azuay, most of whom were women (66.8%), with a mean age of 35.4 years. Participants completed the Coparenting Relationship Scale. Results: The findings revealed adequate reliability of the scale in the Ecuadorian sample. In addition, factor analysis showed that the scale structure remained consistent in this sample, suggesting that the items grouped in the dimensions established by the original scale retain their validity in this specific context. Significant factor loadings consistent with the theoretical dimensions of the scale were observed, reinforcing its construct validity. The sixth model (M6), with three factors and 22 items, showed a good fit (χ² = 399.43, df = 206, χ²/df = 1.94, p = 0.136), with adequate fit indices (CFI = 0.990, GFI = 0.996), a low approximation error (RMSEA = 0.033, 95% CI = [0.028–0.038]), and good residual fit (SRMR = 0.047). Additionally, the ECVI was 0.623. Conclusions: The Coparenting Relationship Scale is a valid and reliable instrument for assessing coparenting dynamics in Ecuadorian parents, providing a solid basis for interventions and policies aimed at strengthening family well-being in Ecuador.
