Adolescence is a journey to adulthood. This book seeks to examine the ways in which young people navigate through this period of their lives, and the consequences their efforts have on their well-being and problem behaviours. In twelve chapters, European researchers will conceptualize, present data and discuss the following: 1) the explorations and commitments adolescents construct as tools with which to direct their lives across the diversity of pathways to adulthood 2) the kinds of identities and self-concepts they develop during this process 3) the role of significant others, such as parents and peers, play in this navigation through adolescence.
