The book, a special issue of the Journal of Research on Adolescence, includes a number of invited contributions by international leaders in the interdisciplinary field of adolescence development. Each paper is intended to review a major subfield of study within the interdisciplinary field of adolescence studies. Each article reviews scientific and scholarly research published during the first decade of the 21st century (2000-2010). Authors were asked to consider contributions from multiple disciplines, and to review important and influential theoretical methodological innovations, and key empirical findings with attention to diversity in representations and populations of adolescents. The Decade in Review issue has the potential for becoming a signature contribution of JRA. As such, the Decade in Review will further establish JRA as the premier journal in the field, and will be an anchor for the journal's impact factor. With a diverse set of topics and contributors, the issue could attract a national and international new readership to the journal and potential membership for the Society. Established scholars and undergraduate and graduate students will cite the papers in their scholarly work in the next decade and beyond.
