[Diagnostic difficulties in adolescent patients--subjective psychiatrist-side factors].

Adolescence is a period of intensive development and crucial transitions in human life. Developmental crises, oppositional behaviours and non-adaptive patterns are strengthened. Simultaneously some symptoms of mental disorders appear mostly in poor organised, non-specific prodromal syndromes. In these unstable and developmentally modified conditions psychiatric diagnosis and treatment seems to be very difficult. In the paper, we described the influence of countertransference of the psychiatrist on the diagnostic processes, especially the influence of a psychiatrist's adolescence on his/her unconscious attitude to adolescence at all.
