Long-Term Study of Youth Mentoring

Thank you for your interest. This page was written for persons who received a phone call or letter from Dr. David DuBois, inviting them to participate in a research study about mentoring.

Cover of Public/Private Ventures Report


In the early 1990s, the nonprofit research organization Public/Private Ventures set out to evaluate the Big Brothers Big Sisters mentoring program. A total of 1,135 youth from eight U.S. cities took part in the study. Participants completed surveys over a period of 18 months. Approximately half of the participants were matched with a mentor (Big Brother or Big Sister) during the study, and half were not.  

Current Study

Now, more than 20 years later, a new national study is being conducted to follow up with participants from the original Public/Private Ventures study, who are adults now. The findings will help increase understanding of how to best support young people for long-term success and well-being. 

The new study is being led by David DuBois, PhD. Learn more about Dr. DuBois and the research team below.

All those who took part in the original research are being invited to participate in the new study. The study is funded by the Office of Juvenile Justice and Delinquency Prevention of the U.S. Department of Justice.

Participant Information

This study is open only to those who participated in the original Public/Private Ventures study.

There are two steps to participate in this study:

  1. Review and complete the study consent form, and
  2. For those who agree to participate, complete the study survey.

Dr. DuBois and the research team ask all participants from the earlier study to at least review and complete the study consent form. Those who agree to participate in the new study will also complete a survey. The survey, which takes 20 to 25 minutes, can be completed online, by phone or by mail.

For reviewing and completing the study consent form, participants will receive $5 as a token of our appreciation, even if they decide to not participate further in this study.

For completing the study survey, participants will receive an additional $45, for a total of $50.
