One of the most interesting and exciting ages in human development is the adventure of adolescence, which today is widely regarded as a period of life marked by narcissistic grandiosity, moodiness, confusion, and passion. This approximately ten-year period is full of both expectations and tribulations. Adolescents are often unclear communicators, with a propensity to prefer action to words. This course addresses the main developmental issues of adolescence from both the psychological and the sociological perspective. We examine some of the psychosocial issues that arise during this stage, such as depression, substance abuse, academic difficulties, and eating disorders. Case material is presented in combination with a discussion of theory and therapeutic techniques used to treat adolescents.
