Planning for success: Trait self-control predicts goal attainment through the use of implementation intentions
The purpose of this research was to examine the relation between trait self-control, implementation intentions, the subjective experience of obstacles, and goal attainment. Across three studies (Ntotal=3,152), participants completed the brief self-control scale, set goals for the next week (Studies 2-3) or next year (Study 1), and then rated whether they had implementation intentions for each goal. In a follow-up survey, participants rated the amount of progress they made on each goal (Studies 2-3). Self-control was positively associated with having implementation intentions (Studies 1-3), which in turn was associated with better goal attainment (Studies 2-3). We also found that both self-control and implementation intentions was negatively associated with the experience of obstacles during goal pursuit (Study 2), but this pattern was not replicated (Study 3). These findings suggest that people with higher levels of self-control are more likely to attain their goals because they use more adaptive strategies, such as implementation intentions.
