Research on physical maturity has demonstrated conclusively that the assumption of an age-homogenous development does not always hold true. This volume presents a biosocial model focusing on the role of individual differences in biological maturation to be used as a framework for empirical studies exploring adolescent female development. The longitudinal design of the research program offers the possibilities to examine both short- and long-term consequences for individual variations in pubertal development. In the present volume, the data for these analyses consist of a broad range of biological, mental, psychological, behavioral, and social factors extending from the age of 10 to the age of 30. Some of the questions the present volume attempts to answer are: * Are variations in the timing of pubertal development among girls related to their psychological and social life situation in the adolescent years? If so, when is the relation most prominent? In what areas is the relation most prominent? How does the relation come about? * Do interindividual differences in physical maturation have any long-term consequences for adult life? If so, in what areas, for which girls, and through which developmental processes does pubertal development operate? The long-term consequences are a major concern addressed in considerable detail.

The authors of this work closely explore the incidence of problem youth behaviors and scrutinize the efficacy of existing prevention programs. This review includes interventions specifically designed to promote youth development or to minimize the long-term consequences of problem behaviors from violence and criminality, substance use and abuse, teen pregnancy and hazardous sexual behaviors, and school failure. Academics and professionals in public health social work, psychology, and school counseling will find special interest in this important work.

In recent years, dating and romantic partners have been recognized as important peer relations within adolescence and research in this area is just emerging. Peer groups and peer pressure are more well established areas of research into adolescence, with recent studies focusing on peer groups and anti-social behaviour.

The book will be the first in a series of three that examines the latest research in key areas of developmental psychology, edited by Rutger Engels and Hakan Stattin.

This volume will present four areas of peer research: the 'deviancy training' mechanism of peer influence; behavioural genetic analytical techniques in understanding peer selection; romantic partners as peer relationships; and in-school and out-of-school peers studies.
