Abstract
Significant developmental transitions occur during adolescence across multiple areas, particularly in the biological and social realms. This chapter examines linkages between key developmental transitions and adolescent social anxiety. Specifically, it reviews literature on school transitions and associated changes in adolescents’ peer relationships; biological transitions, such as the timing and onset of puberty as well as associated physical changes; the emergence of romantic relationships and sexual activity; and family-related interactions, especially those affecting adolescents’ growing autonomy within the family. To the extent possible, for each of these key areas, we discuss pathways by which common developmental transitions might contribute to social anxiety and, in turn, why socially anxious youth might have trouble negotiating transitions. We conclude the chapter with a brief summary and recommendations for further research and practice.
