Adolescence is the most important period of human life. Poets have described it as the spring of life of human being and an important era in the total life span. The word adolescence comes from a Greek word 'adolescere' which means 'to grow to maturity'. A number of definitions have been given by Psychologists from time to time. Some Psychologists define it as the transitional period of life. The child experiences a number of changes in this transitional period. The period runs between childhood and adulthood and is some times called the period of teenage.

According to A. T. Jersild "Adolescence is that span of years during which boys and girls move from childhood to adulthood, mentally, emotionally, socially and physically".

Chronologically adolescence comes roughly in between the years from 12 to the early 20's. The onset of adolescence varies from culture to culture depending on the socio - economic conditions of the country. In this period, great changes occur in all developmental dimensions of the individual.
