Abstract

There is a large number of studies that have attempted to discover associations between psychopathy and personality traits belonging to the Big Five model. However, findings about relations between psychopathy and schizotypy are much lesser in the extent, and unequivocal in interpretation. In this research, we tried to search for connections between Big Five traits, Disintegration, as a construct which examines pro-psychotic personality traits and psychopathy, in a sample of adolescents who are institutionalised in a reformatory home.

Research was conducted in a reformatory home in Kruševac. 78 boys participated in it, and the number of questionnaires with usable data was. The average age of participants in the sample was 18.65 years, with a standard deviation of 1.69. Basic personality traits were assessed with the BFI questionnaire, Disintegration was measured with DELTA 10 and psychopathy measures were collected with the SRP3 questionnaire.

Results of research showed systematic positive correlations between Extraversion and negative correlations between Agreeableness and psychopathy. Neuroticism has positive correlations with the aspect of psychopathy named Erratic lifestyle. Disintegration has positive correlations with all of the psychopathy measures. Mania, Paranoia and Flattened affect are the modalities of Disintegration, which also correlate with all psychopathy aspects. Hierarchical linear regression pointed out that Big Five traits have a larger part in predicting personality aspects than Disintegration modalities. Using the "backward" method of linear regression, all significant predictors are identified. Among them, the Agreeableness factor was a stable predictor of all four aspects of psychopathy as criteria. Canonical correlation analysis confirmed associations between Agreeableness, Extraversion, Paranoia, Mania and General executive impairment with the aspects of psychopathy. Finally, the Exploratory principal component analysis was applied in a shared space of all examined constructs. Three pathways between basic personality structure and psychopathy were isolated in it. First extracted component, describing these relations, was defined mostly by Agreeableness and Flattened affect, together with all psychopathy measures. The highest loadings on the second component have Paranoia and Mania, followed by Extraversion, while the loadings of Neuroticism and Conscientiousness were negative. Interpersonal manipulation was the only psychopathy trait that loaded on this component. The third component was structured by Neuroticism, General executive impairment and negative loadings of Social anhedonia, together with Erratic lifestyle as an aspect of psychopathy. All of the analyses that were performed resulted in mutually congruent findings, offering a precise picture of relationships between basic personality traits and psychopathy in the delinquent adolescent sample.
