Adolescence was once believed to be a time of stress and turmoil. Although this is sometimes the case, research has shown that most adolescents rate their experiences as enjoyable and that the storm and stress of adolescence actually occurs at a fairly low rate and discontinuously. Nonetheless, adolescence is still a time of significant change and development on all levels (psychological, social and biological). Along with all these changes adolescents are faced with situations in which they must make important choices and decisions. Namely, decisions made regarding risky behaviours become more prevalent at this time. Adolescents are faced with decisions on whether to make an effort to have safe sex and how to react to peer pressure regarding substance abuse for example. So how does the personal fable, a form of egocentrism usually considered to be characteristic of adolescence, relate to adolescents' risk-taking behaviours?
