Although the picture of adolescence G. Stanley Hall (1904) drew over a hundred years ago is no longer accepted, most contemporary researchers agree that the period between childhood and adulthood poses a serious challenge to the developing individual. The developmental achievements typical of this age, such as radical changes in appearance and behaviour, severe criticism of existing reality brought about by the recent acquisition of formal thinking, first intimate relations and sexual experiences and the various forms of social pressure connected with the new, age-related demands and expectations can often lead to emotional instability, disturbed parent-child relations and a propensity for risky behaviour (Arnett, 1997). These are the phenomena that accompany the struggle of a young person in the process of self-discovery and self-determination.
