Self-monitoring, the ability to identify the source of self-generated material, represents an important process underpinning attribution biases, characteristic for psychotic and antisocial disorders. The aim of the present study is to investigate the self-monitoring, involving different levels of cognitive effort, in incarcerated and in typically developing adolescents, in relation with schizotypy and antisocial traits. Fifty-one incarcerated adolescents (17 females; m age= 15.73, SD=1.37) and 79 community adolescents (25 females; m age=15.9, SD=1.37) participated in the study. Self-monitoring was tested using a silent/overt reading task. Analyses targeted the potential externalization and internalization biases during the task. Personality traits were assessed using the Schizotypal Personality Questionnaire. Mann-Whitney test indicated that incarcerated adolescence report more disorganized manifestations of schizotypy, U= 4 751, p=. 03. The results of 2x2 repeated measures ANOVA for attribution biases in conditions of cognitive effort indicate an overall group effect F(1, 108)= 6.13, p=.01 and an interaction effect, F(1, 108)=5.04, p=.02. These results suggest that, in the high cognitive effort condition, the incarcerated adolescents present an externalization bias, whereas the community adolescents show an internalization bias in the high cognitive load condition and an externalizing bias in the low cognitive effort condition. In conclusion, the results indicate that the incarcerated adolescents present an externalization bias in the high cognitive effort condition, whereas the community adolescents present the reversed pattern. Future studies are needed in order to explore the implication of the self-monitoring biases in the development of behavioral problems during adolescence and their interactions with schizotypal dimensions of personality.
