We conducted a comparative study of the outcomes at 7 years and at 17 years after initial diagnosis of 77 cases of adolescent developmental psychopathology. The results suggest that the prognosis of adolescent developmental psychopathology could be derived at 5-6 years after commencement of medical treatment. The parent-child relationships during infancy to adolescence, considered to affect the long-term prognosis of adolescent developmental psychopathology, was studied. It is believed that the emotional bond between parents and children in early to middle childhood are vital which seems to affect their relationships during pre-adolescence to early adolescence and to the development of adolescent turmoil. It can be considered vital that the development of the infantile provocative state during preadolescence to early adolescence should progress to a more mature ability to negotiate and which forms the core of adolescent turmoil. The function of the latter will bring better results to adolescent developmental psychopathologies.
