Abstract:

This paper builds on a prior study where FAST® was implemented following a group-randomized design measuring parent social capital both before and after the treatment period. The prior study found evidence that FAST has a significant effect on reducing student peer problems. This paper extends the study by conducting a causal mediation analysis using FAST as a case study, and concludes that the causal effect of FAST on peer problems mediates through parent-improved inter-generational closure.
