This report of the foundation's Child Trends research is presented as a reference to identify the approaches that are most likely to succeed or fail in reaching the adolescents of a community.

Child Trends undertook a comprehensive review of more than 1,100 research articles on adolescent development and the factors- both positive and negative- that affect it. Seven specific areas were covered in this review: reproductive health; physical health and safety; social skills; education; mental and emotional health; and civic engagement.

Child Trends synthesized findings from this body of research first in seven lengthy and fully-referenced reports. Then, the reviews were summarized in a series of seven short research briefs, collectively called the American Teen series, which were published in 2002. These briefs "translate" research findings into language that is easily accessible for policy makers and service providers in the field of youth development and other individuals who are concerned about adolescents.
