ABSTRACT
Once launched into the tumult of the teen years, there is no return to the comparative security and calm of childhood. The relatively ordered progression of skill and knowledge acquisition gives way to fits and starts, highs and lows, isolation and intimacy. Adolescence is often defined biologically as a period of sexual and physical transformation from child to adult; these are the universal changes of adolescence (Cobb, 2001). The remaining challenges-emotional, cognitive, and relationalmay vary by individual and culture. Nevertheless, teenagers are probably the most homogeneous age-related demographic. No matter where you go in the world, teenagers face similar challenges as they move to adulthood.
