Abstract

Background: Aberrant salience is the incorrect assignment of salience, significance, or value to different innocuous stimuli that might precede the onset of psychotic symptoms. The present study aimed to perform a preliminary evaluation of potentially different correlations between the Aberrant Salience Inventory (ASI) score and dimensional or categorical diagnostic approaches.

Methods: 168 adult outpatients with a current psychiatric diagnosis were consecutively enrolled. Patients were evaluated using different psychometric scales. ASI was used to evaluate aberrant salience, and to evaluate the association between ASI scores and first rank symptoms (FRS), and/or with a psychiatric diagnosis. Principal dichotomic clusters of ASI were identified using the Chi-square automatic interaction detection (CHAID) method.

Results: Current (16.76 ± 6.02 vs 13.37 ± 5.76; p = 0.001), lifetime (15.74 ± 6.08 vs 13.16 ± 5.74; p = 0.005) and past (15.75 ± 6.01 vs 13.33 ± 5.80; p = 0.009) FRS were the main clusters dichotomizing ASI. The average ASI score did not significantly differ among patients with different diagnoses.

Conclusions: ASI could be used as a tool to identify psychopathological dimensions, rather than the categorical diagnoses, in the schizophrenic spectrum.

Keywords: Aberrant salience; Dimensional approach; Psychotic symptoms; Schizophrenic spectrum.
