“…Among the sample of patients affected by psychotic symptoms or schizophrenia, 217 (73.8%) were under antipsychotic medication, while no data was available for the remaining portion. One of the included studies performed an invariance analysis (Rodríguez‐Testal et al ., 2022), showing that age, gender, and clinical condition do not modify the subject's interpretation of ASI items. The gender invariance was also proved in the original validation study (Cicero et al ., 2010).…”

“…The data extraction is shown in Table 1. Four authors provided raw data for the patient‐level meta‐analysis, for a total of 1,960 subjects, 294 of whom were in the psychotic group and 1,660 in the non‐psychotic control group (Cicero et al ., 2010; Golay et al ., 2020; LeIli et al ., 2015; Rodríguez‐Testal et al ., 2022). Risk of bias assessment is shown in Supplementary Material S1–S3.…”

“…Moreover, the sample was imbalanced concerning gender distribution (see Results) and mostly focused on Europeans and African Americans, while the Asian sample and other ethnicities were almost absent (see Results). Finally, since past research has shown that ASI scores might be positively influenced by young age (Rodríguez‐Testal et al ., 2022), we limited our sample to adults only; thus, we cannot make any inference on previous stages of the psychosis process.…”

“…Regarding the IPD meta‐analysis, some of the aforementioned limitations persist, such as the limited number of studies and their imbalance in sample size: Most of the IPD sample was extracted from two studies (Golay et al ., 2020; Rodríguez‐Testal et al ., 2022). Moreover, ASI cutoffs must always be taken with caution, since the PPVs, especially in the general population, are quite low (Zimmerman, 2022).…”

“…In the past few years, a significant amount of quantitative data has been gathered on salience alterations. One of the main tools employed to investigate this phenomenon is the Aberrant Salience Inventory (ASI; Cicero, Kerns & McCarthy, 2010): Its psychometric properties seem to make it a suitable instrument for early detection of psychosis as evaluated in different settings (Pelizza et al ., 2021; Raballo et al ., 2019) and countries (Golay et al ., 2020; Rodríguez‐Testal et al ., 2022). ASI is clinically relevant in ultra‐high‐risk subjects (UHR) as well, with no differences in scores with first‐episode‐of‐psychosis (FEP) patients (Azzali et al ., 2022; Poletti et al ., 2022); furthermore, its usefulness is underlined by the fact that attenuated positive symptoms are the principal risk factors for psychosis onset in high‐risk individuals (Oliver et al ., 2020).…”

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.

the present paper describes the preliminary results of a study centered on the effect of salience alterations and cannabis use on the intensity of psychotic symptoms in adolescent and adult cohorts. The exploratory analysis focused on cross-sectional scores at psychometric questionnaires of 64 participants allocated to 4 different subgroups. A hierarchical pattern in the psychopathology measures was observed in the adult subgroups, with Psychotic patients scoring higher in several domains than other patients from the Psychiatric and Neurologic Units; in turn, adolescents reported a more severe intensity of psychotic symptoms at the Positive and Negative Syndrome Scale subscales (p-value: < 0.05) when compared to adult one, while no significant difference was observed in cannabis exposure or Aberrant Salience Inventory scores (p-value: 0.22). These results suggest that aberrant salience and, to a lesser degree, cannabis use might play a role in determining psychotic symptoms severity, especially in more at-risk life phases. Public Significance Statement: the present study displays how salience alterations in younger patients might lead to intensified psychotic symptoms, while exploring parallel psychopathological domains and explaining the layout of a wider project. The role of cannabis use in this equation is still to be clarified.
