Aim Aberrant salience has been considered as a predisposing factor during prodromal phases of psychosis and in ultra high‐risk subjects. Most studies investigated the presence of aberrant salience in general population as a measure of vulnerability to psychosis. This study aimed atinvestigating the level of aberrant salience in a sample of Italian high‐school students. Methods Aberrant salience was measured with the Aberrant Salience Inventory (ASI) and its association with measures of general psychopathology (Youth Self Report [YSR]) was tested. A sample of 312 high school students (115 boys, 197 girls; age range: 14 to 19) was recruited. Results Within the ASI and the YSR, the subscales did associate with each other at medium to large effect size, while the associations of the ASI subscales to the YRS scales had small effect sizes, indicating that the two tools measure different constructs. Latent Class Analysis revealed a distribution of aberrant salience across three classes with the intermediate class corresponding to more than half of the sample (58.3%). The class with the highest endorsement of the ASI items included 101 subjects (32.4%). Greater differences by classes were found in the “increased significance” and the “impending understanding” subscales. Higher aberrant salience was found on the anxious/depressed, the somatic complaints, and the thought problems scales of the YSR. Conclusions Aberrant salience represents a common experience in the adolescent population and is associated with various psychopathological disorders, in particular, thought disorder. Aberrant salience might be involved in proneness to psychosis.
