Adolescence is viewed as a transitional period between childhood and adulthood, whose cultural purpose is the preparation of children for adult roles.It is a period of multiple transitions involving education, training, employment and unemployment, as well as transitions from one living circumstance to another.The term depression is used in normal and clinical sense. As a normal mood, depression is referring to a reaction to stress e.g., to grieve after the loss of a loved one. However, as a clinical term depression as used by psychiatrist describes a long period when a person feels very sad to the point of feeling worthless, hopeless and helpless.Moods and mind are beyond the control of a large majority of people. Cognitive explanations rose to prominence in dealing with these issues and as a reaction to the early behaviorists' failure to take thoughts and feelings seriously. For the past five decades, the cognitive theories have gradually integrated the behavioural framework into its fold.Depression is a commonest problem among them. There is a need to help overcome this scourge of adolescents by CBT psychotherapy.
