The Alabama Parenting Questionnaire (APQ) is a well-known tool to assess empirically identified aspects of positive and negative parenting practices. This study evaluates the psychometric properties of an adapted version of the APQ for its use with parents of children between 2 and 6 years of age in Chile. The participants were 557 parents of children aged 2 to 6 years. A confirmatory factor analysis showed that the best fit was obtained by a four-factor model (positive reinforcement, parental involvement, inconsistency of disciplinary practices, and punitive practices). The invariance analysis for this model by sex and social composition was positive. Disciplinary inconsistency and punitive practices were correlated with externalized and internalized behaviors in children. Results suggest that this adaptation of the APQ may result in a useful tool for clinical and research purposes in this age group.
