Big Brothers Big Sisters (BBBS)

Big Brothers Big Sisters (BBBS) matches volunteer mentors with disadvantaged or at-risk youth mentees (CEBC). BBBS provides a mentoring program design to its network of independent agencies. The program focuses on building supportive relationships rather than addressing problem behaviors (PPN). In the community-based version of BBBS, mentors spend about four hours per week engaging mentees in conversation and social activities for at least a year. In the school-based version, mentors meet mentees at their schools once a week during the academic year to engage in academic activities, conversation, and indoor games (CEBC).

Expected Beneficial Outcomes (Rated)

  • Reduced delinquent behavior

  • Increased academic achievement

Other Potential Beneficial Outcomes

  • Reduced aggression

  • Improved family functioning

  • Improved social skills

Evidence of Effectiveness

There is some evidence that Big Brothers Big Sisters (BBBS) reduces delinquent behavior and improves school outcomes among mentees (CEBC, PPN, OJJDP Model Programs). Additional evidence is needed to confirm effects.

Community-based BBBS can reduce youth’s aggressive behavior, improve relationships with parents, prevent minority boys from initiating illegal drug use, and improve girls’ academic performance (PPN, Child Trends-Lawner 2013). School-based BBBS appears to improve academic performance for youth whose matches remain intact for the duration of the school year (). Programs that recruit high school students as mentors (“High School Bigs”) have demonstrated better peer relationships among mentee students than non-mentored peers (Herrera 2008). Youth entering the program with adequate parental relationships (neither very strong nor very poor) benefit the most from school-based BBBS ().

Research suggests that longer, closer matches yield stronger behavioral (, ), mental health (), and academic effects (, , Herrera 2007), possibly by enhancing the mentee’s relationships with teachers and parents (). Mentors who are college students appear less likely than other mentors to continue matches. Researchers recommend screening, training, and post-match support to ensure that matches continue ().

In school-based programs, mentoring meetings after school or during lunch time may have greater effects on academic outcomes than meetings held during school hours (). Researchers caution against using BBBS mentors primarily as tutors, as such matches appear less likely to endure (), and instead, recommend helping academically focused pairs connect interpersonally ().

Implementation Examples

From July 2010 to June 2011, BBBS served about 120,000 community-based mentees and 87,000 school-based mentees (BBBS-Annual report 2011).
