Aim of the study:
The purpose of the study was to describe consequences of depression in adolescence. The history of health problems and the choice of life careers, were selected as indicators of the nature of depressive syndromes appearing through adolescence. Since the ’70s, adolescent depression has been discussed to be related to developmental crisis or a form of affective disorder.

Subject or material and methods:
The methods employed for this baseline study was screening youngsters of school age. A sample of youngsters from different schools and different backgrounds were screened through Kraków Depression Inventory (KID) in 1985. There was a second study done 15 years later and a third study 30 years later. The questionnaires written by original authors were sent out. A preliminary analysis of the responses to the third study is presented.

Results:
The results showed that there were no significant differences, between depressive students and the non depressive peer group.

Discussion:
Discussion: the correspondence method which was employed was found to be limited, as there was a small number of replies received and therefore, they have limited the significance of our findings. Nevertheless it was found that the differences, between the life health histories of the group studied and that of a non depressive peer group were negligible or not at all.

Conclusions:
Conclusion: results of long term prospective study, support the conception of developmental character of adolescent depression.
