Plans Are More Helpful When One Perseveres: The Moderating Role of Persistence in the Relationship Between Implementation Intentions and Goal Progress

Two studies investigated whether one dimension of action-state orientation, namely, persistence-volatility, would moderate the effect of implementation intentions on goal progress. Results from Study 1 indicated that spontaneous implementation intentions predicted goal progress 2 weeks later only among participants who scored high on persistence. In Study 2, participants were randomly allocated to an implementation intentions group and a control group. Results indicated that persistence was positively associated with goal progress among participants in the implementation intentions group but not among those in the control group. Theoretical and practical implications of these findings were discussed.
