The association between parenting behaviors and the outcomes of children has been widely studied, with results commonly linking parents' attitudes and behaviors with child outcomes. Few studies, however, have examined and analyzed the link between differential or inconsistent parenting within families and the academic and behavioral outcomes of siblings. Thus, the main purpose of this study was to explore the relations between differential parenting within families and the academic and general behavioral outcomes of pairs of siblings. Included in this study were variables that represent parenting factors (demandingness and responsiveness) and child outcomes (academic grades and behaviors). Unique to this study was the computation of a new variable, Parental Differential Treatment (PDT score) for responsiveness and demandingness separately, to reflect whether parents were consistent or inconsistent in the ways that they parented their two children. The role of temperament in parents' differentially parenting their children was also measured. Finally, this study also examined the relation between parental differential treatment and child outcomes when controlling for child temperament.
