“…This theory is supported by research indicating that depressed mothers are more likely to use inconsistent, lax, avoidant and ineffective discipline practices (e.g., Gelfand and Teti 1990). Parenting practices, including discipline practices, level of supervision, and parental support, have in turn been linked to aggressive and problem behaviors among youth (Sheehan and Watson 2008). More direct support for this theory is provided by studies showing that parenting practices, such as inconsistent discipline practices, parental nurturance, parental rejection, and low parental monitoring, mediate the relation between maternal depressive symptoms and adolescents' aggression (e.g., Barry et al 2009;Elgar et al 2007).…”
