Aiming to establish teenagers' diagnoses in cases group, clinical psychiatric research was performed, in accordance with ICD- 10 classification of mental and behavioural disorders diagnostic reference requirements, diagnoses distribution was compared in relation to sex. Minnesota Multiphasic Personality Inventory (MMPI) was used to evaluate personalities in both groups, obtained profiles were compared among groups and sex.

depression diagnosis (F32) was established only to 22,9% of teenagers, more cases were established among boys than girls (p<0,001). Adjustment disorders (F43) and disorders of conduct and emotions (F91-92) diagnoses were more frequent among girls (p<0,001). Cases group boys in MMPI profile more often than girls had greater scales of depression, psychasteny and anxiety, girls, relatively, had greater scales of hysteric, psychopathic and mania (p<0,05).
