FFVP is a purchase‐support intervention used to increase intake and variety of fruit (F) and vegetable (V). To study the role of mediators on 4 F/V eating behaviors (daily variety of F/V, asking parents to buy F/V), 4 th graders in 8 intervention (IN) and 8 control (C) schools (n=1611) completed 58‐item questionnaires about intake, intentions to eat F/V, and, attitude, subjective norms and perceived behavioral control, both prior to and 8 months into intervention. Data were analyzed to determine total effects of the intervention × time interaction on 6 separate situations including, daily variety F/V consumed, asking parents to buy F/V, intention to eat more F/V, with multiple regression. Indirect effects were measured using 10 simple mediation analyses following multiple regressions by product of coefficients. These 10 analyses included 4 paths mediating behaviors and 6 mediating intentions. IN increased daily variety of F (p=0.015) and V (p=0.017), more frequently asked parents to buy F (p=0.002), and intended to eat more F (p=0.004) & V (p=0.009) compared to C. IN improved global F attitudes (p=0.016) but only one attitude toward eating V (p=0.017). Effects of intervention on eating more types of F/V and asking parent to buy F were mediated by intention. Intentions to eat more F/V were mediated by attitude. FFVP may have improved F and V eating behaviors by indirect influences from intention and attitude.
