ABSTRACT What good is self-control?We incorporated a new measure
of individual differences in self-control into two large investigations of a
broad spectrum of behaviors. The new scale showed good internal
consistency and retest reliability. Higher scores on self-control correlated
with a higher grade point average, better adjustment (fewer reports of
psychopathology, higher self-esteem), less binge eating and alcohol abuse,
better relationships and interpersonal skills, secure attachment, and more
optimal emotional responses. Tests for curvilinearity failed to indicate any
drawbacks of so-called overcontrol, and the positive effects remained after
controlling for social desirability. Low self-control is thus a significant risk
factor for a broad range of personal and interpersonal problems.
