Psychology Professor Janet Kistner found that children in third through fifth grades who had the wrong idea about their level of social acceptance were more likely to develop symptoms of depression over time. The study, "Bias and Accuracy of Children's Perceptions of Peer Acceptance: Prospective Associations with Depressive Symptoms," was published in the Journal of Abnormal Child Psychology. Graduate students Corinne David-Ferdon and Karla Repper and psychology Professor Thomas Joiner were co-authors.
"There's a long-running debate in the field of psychology about whether realistic perceptions are a hallmark of positive adjustment or they are associated with risk for depression," Kistner said. "Our results support the perspective that realistic perceptions are a hallmark of mental health."
