Associations between schizotypal traits and antisocial behaviours in a sub-Saharan sample.

Schizophrenic symptoms have often been associated with antisocial behaviours (ASBs). Most studies have focused on violence. The association between schizophrenia and violence is often confounded by socio demographic characteristics of patients. Overemphasis on diagnosis, rather than traits, and the traditional focus on violence may have obscured associations between psychotic features and antisocial behaviour. In this study, an analogue sample (n = 604, females = 54.4%, mean age = 21.46, SD = 5.89) completed self-report measures of schizotypy and antisocial behaviours. The aim was to identify the strength of associations between different schizotypal traits/symptoms (unusual experiences, cognitive disorganisation, impulsivity & introvertive anhedonia) and different forms of antisocial behaviour (rule breaking, physical aggression & social aggression). Differential patterns of association between genders were also considered. Traits akin to positive symptoms were more strongly associated with antisocial behaviours. Impulsive non-conformity was associated with rule breaking, physical aggression and social aggression for both males and females whilst unusual experiences traits were associated with physical and social aggression in both males and females but had only a weak (gender-nonspecific) association with rule breaking. Finally, cognitive disorganisation was not associated with any class of ASB for males but was associated with physical and social aggression in females. These specific associations could inform the development of more targeted treatment approaches for specific types of ASBs in males and females.
