Antisocial Behavior and Attitudes Towards Antisocial Behavior after a Five-Year Municipal Youth and Family Master Plan in Pomona, California, USA.

Within an integrated conceptual framework made up of social cognitive theory, theory of fundamental causes, and the risk and protective factor approach, we assess reported antisocial behavior and favorable attitudes toward antisocial behavior among youths and parents in a high-school sample after the implementation of a Youth and Family Master Plan in Pomona, California, USA from 2005 to 2009. We perform z tests for same students (8th grade 2005 and 12th grade 2009), same grade (8th,10th, and 12th grade), inter-grade, same year, and overall, 2005 to 2009 comparisons for Pomona, Los Angeles, and US national samples. It was hypothesized that after five years of implementation, Pomona Youth and Family Master Plan (PYFMP) activities will reduce antisocial behavior and favorable parental and youth attitudes toward antisocial behavior. Within a p-value of 05, z-test results show a decline in youth antisocial behavior among youths in the Pomona sample. Patterns in youth antisocial behavior were not consistent with youth favorable attitudes toward antisocial behavior but were consistent with perceived parental favorable attitudes toward antisocial behavior. Though youth favorable attitudes toward antisocial behavior were generally rising within the Pomona data, when compared to the rates of change in Los Angeles and US, Pomona rates of change were lower. Intra and inter jurisdictional patterns above could be attributed to the community multicomponent interventions of the PYFMP. They also align with assumptions and explanations offered in the integrated conceptual framework, which suggest a mediating role for environmental factors.
