Piquero's Meta-Analysis

Better Essays

In a meta-analysis addressing the effectiveness of parent training programs on reducing problem behaviors in children, Piquero, et al. (2009) created a lengthy list of guidelines for future research on developmental prevention strategies. This list included 11 different ideas, all of which Piquero et al. found to be important for the advancement of knowledge in area of developmental prevention. Of particular importance was the fourth suggestion: “there is a need to identify the particular ingredients that make the specific early family/parent training programs successful at inhibiting antisocial and delinquent behaviors” (pg. 108). If researchers chose to prioritize that over other research options, then more focused efforts could be made to …show more content…

Looking again at the meta-analysis by Piquero et al. (2009) shows that out of the 55 studies they analyzed for effects on antisocial behavior and delinquency, 34 had non-significant effect sizes. Despite the fact the analysis had an overall significant effect size for antisocial behavior and delinquency, clearly many of the individual studies failed to find strong results. If researchers could figure out exactly what aspects in these programs were not effective, then policymakers and researchers could move on to including items that do not incorporate these unnecessary components. For instance, if a program similar Triple P or Incredible Years was overall successful in reducing antisocial behavior, then they could reduce the size of the program by removing some of the unnecessary or ineffective components. Since these programs are large and incorporate a large number of different aspects, reducing their size could increase parents’, teachers’, children’s, and schools’ willingness to participate in them. If some components of programs simply do not help reduce antisocial behavior (or have a positive change in another program goal) then it should not reduce the effectiveness of the program to remove that component. Additionally, by removing some unnecessary items from programs, the cost could be reduced, which would also make the programs more palatable to policymakers or …show more content…

Piquero et al.’s (2003) second suggestion of including longer sampling periods to assess effects on delinquency longitudinally. If researchers do not even know which program components are most successful then it seems unnecessary to do longitudinal research until they have some idea what works in the short term. The sixth suggestion of improving operational definitions for key terms is rather important for research design as well. This one is more important than most of the other suggestions, but as long as individual studies still state how they are operationalizing variables then the fourth item still is more important. Finally, the eighth suggestion to have more theoretical work to show a causal relationship between families and offending seems less important since it seems unnecessary to use a high level research design if we do
