Abstract:
Founded in family systems theory, the spillover hypothesis suggests that marital relationships are linked to parenting. The current study used meta-analysis to extend this literature and examine links between marital positivity and marital negativity with absolute levels of parental differential treatment (PDT) of siblings. Multilevel data included 2575 effect sizes nested within 45 sources (articles/raw datasets), nested within 12 unique samples.
Keywords:
differential treatment; family systems spillover; favoritism; marital quality and relationships; parenting; siblings
