Self-control, the ability to regulate prepotent desires or impulses in order to realize one's valued goal, has been found to be associated with early life adversity. However, the neural correlates underlying this relationship remain poorly understood. The present study employed resting-state functional magnetic resonance imaging (fMRI) to investigate this issue among late adolescents (N = 538). Results showed that family unpredictability rather than family harshness of early life adversity was negatively correlated with self-control ability. The whole brain analysis showed that self-control was associated with enhanced ALFF in the right middle and inferior frontal gyrus, the left anterior insula, and with decreased ALFF in the left precuneus. Moreover, the mediating analysis showed that ALFF in the inferior frontal gyrus could partially mediated the association of family unpredictability with self-control ability. These findings suggested that the brain regions implicating in executive control might be the neural correlates underlying the relationship between early life adversity and self-control ability, which advances the mechanistic understanding of how early family environment relates to the development of self-regulation in late adolescence.
