IntroductionThe Aberrant Salience Inventory (ASI) is a useful tool to measure salience abnormalities among the general population. There is strong clinical and scientific evidence that salience alteration is linked to psychosis. To the present day, no meta‐analysis evaluating ASI's psychometric properties and screening potential has been published.Materials and MethodsPubMed, Google Scholar, Scopus, and Embase were searched using terms including “psychosis,” “schizophrenia,” and “Aberrant Salience Inventory.” Observational and experimental studies employing ASI on populations of non‐psychotic controls and patients with psychosis were included. ASI scores and other demographic measures (age, gender, ethnicity) were extracted as outcomes. Individual patients' data (IPD) were collected. Exploratory factor analysis (EFA) was performed on the IPD.ResultsEight articles were finally included in the meta‐analysis. ASI scores differ significantly between psychotic and non‐psychotic populations; a novel three‐factor model is proposed regarding subscales structure. Theoretical positive predictive values (PPVs) and negative predictive values (NPVs) were calculated and presented together with different cutoff points depending on preselected specific populations of interest.DiscussionPPV and NPV values reached levels adequate for ASI to be considered a viable screening tool for psychosis. The factor analysis highlights the presence of a novel subscale that was named “Unveiling experiences.” Implications regarding the meaning of the new factor structure are discussed, as well as ASI's potential as a screening tool.
