Left out, sluggardly, and blue: Low self-control mediates the relationship between ostracism and depression

Ostracism strikes at the core of well-being, often increasing depression. Yet, it is unclear whether low self-control may account for the relationship between ostracism and depression. When people experience ostracism, they lose their willingness to control their impulses. This lack of self-control may have negative consequences for ostracized people’s mental health, including their level of depressive symptoms. Using two large, independent samples of young adolescents (Ns = 918 and 487), we examined whether chronic ostracism would relate to lower self-control, which may predict higher levels of depressive symptoms. We found that in both samples, self-control mediated the relationship between ostracism and depressive symptoms. Further, the relationship between self-control and depressive symptoms was moderated by the level of ostracism. Discussion centers on the role of self-control processes in understanding and reducing the negative consequences of ostracism.

► Poor self-control mediates the relationship between ostracism and depression.
► Consistent results found across two large, independent samples.
► Ostracism also moderated the relationship between self-control and depression.
