Objective: Some authors report that aggressive behaviour in schizophrenia is of heterogeneous sources, for example, aggression may be an impulsive action and even deliberate behaviour designed to intimidate others. Violence and aggressive behaviour may also be associated with psychotic experiences, such as delusions or hallucinations. The aim of this study was to explore the relationship between psychotic experiences and the intensiveness of hostility and aggression in patients with paranoid schizophrenia. Material and method: Seventy outpatients (35 men and 35 women) with paranoid schizophrenia were examined. Relevant scales, subscales and indices of the Polish version of Minnesota Multiphasic Personality Inventory (MMPI) were used. Results: The analysis of correlation and the factor analysis revealed a number of statistically significant correlations between the scores of the scales assessing psychotic experiences and those assessing the intensiveness of hostility and aggression. Conclusions: The results of this study confirm the presence of a number of relationships between psychotic experiences and felt hostility and aggression. Psychotic symptoms and indices of aggressiveness created five factors: “psychoticism,” “hostility,” “psychopathic aggression,” “poignancy,” “persecutory ideas.” Important for the felt hostility and aggressiveness in patients turned out to be experienced anxiety about their mental health because of the sense of the unreality of what is going on and because of the sense of alienation of their own thoughts. Another important factor turned out to be a sense of being wronged by life, misunderstood by others, and the belief that people have a grudge and try to harm. In contrast, characteristics, attitudes and behaviour which are the opposite of paranoid disorders, i.e. faith in people and optimistic attitude towards them, are an important factor for the inhibition of aggression.
