The Big Brothers/Big Sisters program establishes supportive relationships between youth and a caring adult in order to promote social, emotional, cognitive and behavioral competencies (Grossman & Tierney, 1998; Tierney et al., 1995). The experimental evaluation of the program examined 959 10- to 16-year-olds. The youth were randomly assigned either to the mentoring or to the control group. An indication of positive conflict resolution strategies, youth in the mentor group reported fewer incidents of hitting during a conflict than youth in the control group.
