  1. Note: for vitamin C, the intervention took place at T0
  2. Significant mediated effects are only represented in the coefficients marked in bold, where more than one significant coefficient makes a complete significant pathway between reward to automaticity. (Items in italics reflect a mediation relationship from reward to automaticity that is via both via intention and behaviour, rather than just via behaviour. The coefficients from reward to intention are marked R-I, and the coefficients from intention to behaviour are marked I-B). Perceived benefit was not measured at Time 2 or Time 3
