We assessed 29 young persons (14-21 years old), who committed crimes according to article 156 of Criminal Code of Ukraine «Depravity of Minors».

Assessment tools: surveillance, clinical and diagnostic interview, objective psychometric scales and test methods to identify the studied trait.

Established 11 youth with developmental delay [5 with mild developmental delay - F70 (17.2%), 3 with moderate (10.3%), and 3 with severe (10.3%)], 12 with behavioral disturbances [2 - F91.0 (6.9%), 4 - F91.1 (13.8%), 5 - F91.2 (17.2%), 1 - F91.3 (3.4%)], 6 - were found to be mentally healthy (20.7%). Sexual benefit of committed crime (importance of satisfaction of sexual desire or relief of sexual arousal) confirmed only in 7 youth (24.1%). Most of them were mentally intact (5; 17.2%) and belonged to an older adolescent group (19-21 years). Remaining participants, who were developmentally delayed, called curiosity and desire of knowledge of sexual differences of another sex, as their most important motives for crime. Another group, juveniles with behavioral disturbances, cited physical humiliation or ritualistic punishment (particularly these were seen in oral-genital encounters) of their victims as rationale. In this group there were frequent cases of group rape, as opposed to first group where sexual encounters have been mostly individual. In the meantime the most deprived character of sexual relation was noted among mentally healthy minors.

None of the assessed has shown signs of diagnosis G1-G3. Diagnosis of F65.4 has been completely excluded despite the potential of some negative prognosis in future.
