A Quasi-Experimental Effectiveness Study of Triple P on Child Maltreatment

We examined the impact of the implementation of The Triple P-Positive Parenting Program in North Carolina (NC) on reducing child maltreatment, a serious public health problem in the US with lasting harmful effects on children. In 2012 and 2013, 34 of 100 counties in NC implemented Triple P. A panel data set with county-level child welfare data and emergency department (ED) discharge data from 2008 to 2015 for 100 counties in NC was constructed. A quasi-experimental design using difference-in-differences analysis estimated the association between the implementation of Triple P and the rate of (1) investigated child maltreatment reports; (2) entry into foster care; and (3) ED visits concerning for child maltreatment. Implementation of Triple P was associated with in a 4% decrease in the county rate of investigated reports of child maltreatment ( RR = 0.96, 95% CI [0.93, 0.99]) and a 7% decrease in the county rate of children in foster care ( RR = 0.93, 95% CI [0.88, 0.98]). Each of these findings was robust to one but not both sensitivity tests performed. There was no reduction in county-level rates of ED visits with ICD-9-CM codes concerning for child maltreatment. Implementation of Triple P in NC outside of the parameters of scientific study is associated with small reductions in the rates of child maltreatment reports and foster care placements. Additional research is needed to understand whether such small reductions justify the substantial investment communities are making in Triple P.
