Introduction: Year by year the level of suicide attempts among the young people increases systematically and the age at which adolescents attempt suicide decreases. Among the factors connected with suicidal behaviour, literature mentions aggressive behaviour and attitudes. Aim: The aim of the study was specification of the level of aggression, its intensity and the way of expressing it in the group of young persons after suicide attempts. Material and method: The group of subjects after suicide attempts included 99 persons and they were compared with the control group of 301 persons. We used the Psychological Inventory of Aggression Syndrome (IPSA) and the Anger Expression Scale (SEG). Results: The results of the study showed that adolescents after suicide attempts exhibited an increased level of aggression and anger, they found it difficult to manifest in a socially acceptable way the attitudes and behaviours recognized as aggressive; they were characterized by the lack of the capability to express anger or other negative emotions, less often made negative self-estimation, rarely manifested hostile desires in relation to other people and exhibited few seemingly non aggressive behaviours. Moreover, such adolescents rarely transfer their aggression on inanimate objects, they are less noisy, quarrelsome and vulgar, they less often undertake activities recognized as physical violence. Conclusions: The above results may be used to construct strategies, programmes and support groups for adolescents with suicidal tendencies.
