Self-control is the ability to (1) initiate, and (2) persist in boring, difficult or disliked activity, and to (3) inhibit impulses to act. We explored the self-regulatory strategies that people use for these three types of self-control conflicts and their subjective efficacy as a function of conflict type. In addition, we hypothesized that people who more frequently create strategy-situation fit by tying strategies to the conflict types they are effective for, are more successful at self-control. A pilot study identified 22 different self-regulatory strategies that could be used for more than one type of self-control conflict. We then used a large data set from two pooled experience sampling datasets ( n = 14,067 reported self-control conflicts) to quantify these strategies’ popularity and subjective efficacy in daily life. Eight strategies were positively and three negatively associated with subjective self-regulatory success but subjective efficacy often depended on type of conflict: Some strategies were effective and some maladaptive only for some types of self-control conflicts. Individuals who created strategy-situation fit for some strategies also reported greater self-regulatory success, as hypothesized. We discuss regulatory flexibility as a crucial component of good self-control.
