Psychometric properties of the Spanish version of the Dimensions of Discipline Inventory (DDI) in university students. Discipline is a central aspect of parenting that includes the behaviors that parents use to correct children's misbehavior or to achieve their compliance. The aim of this study was to analyze the psychometric properties of the Dimensions of Discipline Inventory (DDI), a multidimensional instrument to measure parental discipline, in a sample of 1097 Spanish university students. Results support the 9-factor structure originally proposed by the DDI authors, clustered in four second-order scales. In order to analyze the convergent validity, the relationship between the types of parental discipline and the presence of physical abuse in childhood were examined. Lastly, practical applications of the DDI were discussed and it was concluded that this instrument is a useful tool to assess the disciplinary techniques used by parents.
