A sizable portion of the current research on the socio-emotional development of children and adolescents focuses on negative outcomes of aversive circumstances.

Creative programs to address these issues have been implemented at the local, regional and national levels, yet rarely are the results of these interventions disseminated to academic audiences in the U.S.
