2. Informal and formal mentoring relationships
Informal or natural mentoring relationships form organically between youth and older individuals within their existing social networks
Formal mentoring relationships are established through a program that matches mentees and mentors and outlines specific expectations about the relationship (e.g., objective, frequency and duration of contact)

3. What works in mentoring?
Mentors may provide support that enhances youth’s sense of belonging and mattering with significant others
By being a companion for youths and providing reliable support, mentors may establish and maintain resilience
Through social interactions with mentors, adolescents acquire and refine new cognitive skills, and become more receptive to adult instructions and perspectives
When identity development becomes central, mentor guidance may help shift youths’ conceptions of both their current and future identities and help them develop ideas of what they might become or would like to become in the future
Mentors can provide a protective role for youth who have had a history of difficult or unsatisfactory relationships
By modeling, caring, and providing emotional support, mentors can challenge negative views that some youth may hold of themselves and others, and let them experience that positive relationships with adults are possible.
Mentors may function as secondary attachment figures who satisfy their emotional and social needs

A greater percentage of helping professionals was associated with larger effects in both meta-analyses

6. Targeted versus Non-targeted Formal Mentoring
The median average effect of universal prevention programs for various outcomes tend to fall within the range of 4% to 9% improvement in youth outcomes.

7. Future Research
To examine the effect of relationship quality in formal mentoring relationships on youth outcomes
To examine whether mentoring can increase treatment motivation, susceptibility to treatment, and treatment adherence
To examine whether mentoring can increase the effectiveness of established psychological therapy
For instance, Levi van Dam and others showed that Youth Initiated Mentoring (YIM) was effective in preventing residential care in youth with complex needs receiving established psychological therapy
