In this book, a range of interesting and diverse papers are presented, which demonstrate the importance of the psychosocial domain to adolescents, as well as the need for intervention programs to facilitate the passage through adolescence to adulthood for young people experiencing difficulties with this developmental transition. The chapters are based on recent research conducted in different countries around the world (eg: Australia, Canada, Israel, Scotland, Ireland and Poland). The book trifurcates into three separate areas, which are reflective of the adolescent domain: the first area highlights the importance of a successful transition from preadolescence to adolescents; the second area highlights the types of difficulties that some adolescents experience when trying to find their identity and sense of place within society; and the third area provides insights into the types of interventions that can be put in place to help adolescents successfully transition into adulthood.
