It would not be possible to thank all the people who supported us in preparing this textbook.
We must ﬁrst thank the entire staff at the American Academy of Pediatrics (AAP), who have
taken this enormous project from a kernel of an idea through fruition. Some people, however,
deserve special mention. We are grateful to Mark Grimes for having the vision to imagine
this idea and the commitment to the well-being of teens to make it happen. Mark Ruthman
has been instrumental in turning this dream into a reality; without his creative thinking and
technical skills, this project simply could not exist. Eileen Glasstetter has shepherded every
detail of this work, somehow managing all of the moving pieces with patience, humor,
skill, and grace. Carolyn Kolbaba’s resolute commitment to supporting the mission of
building the resilience of children and teens continues to nurture us. And Peg Mulcahy has
worked with us to design a book that visually captures the joy of working with teenagers.
We are also grateful to the AAP Adolescent Health Partnership Project (a grantee of
the Partners in Program Planning for Adolescent Health), chaired by Tonya Chaffee and
managed by Charlotte Zia, for its commitment to promote positive youth development.
We are honored to have been part of this mission.
Next, we must offer our appreciation and respect to the leaders of the positive youth
development and resilience movements who have inspired us. In particular, Rick Little and
his team at the International Youth Foundation ﬁrst elucidated the primary ingredients
needed for healthy youth development. We have been particularly influenced by Richard
Lerner of Tufts University, who was part of that team and is one of the great developmen-
tal psychologists of our time. Dr Lerner has spent decades demonstrating that positive
youth development efforts indeed work. In our own ﬁeld of adolescent medicine, Robert
Blum and Michael Resnick have led the way and motivated us to shift from a risk-based to
a strength-based approach to youth, and Karen Hein has made us understand we need to
support youth so they can reach their full potential. Paula Duncan has worked tirelessly to
ensure that as we offer comprehensive care, we do so through a strength-based lens while
simultaneously addressing risks.
