“…The SCID-PD confirmed the diagnosis of avoidant, obsessive-compulsive, and paranoid personality disorder ( 20 ). The patient was also subjected to further psychometric scales, such as the short version of the Temperament and Character Inventory (TCI-125) ( 21 ), Magical Ideation Scale (MIS) ( 22 , 23 ), Perceptual Aberration Scale (PAS) ( 24 ), and Hypomanic personality scale (HPS) ( 25 ).…”

“…Evaluation with MIS demonstrated the presence of magical thinking, obtaining a score of 9/30, which appears higher than the Italian average for age and sex (mean 5.1 ± 4), testifying schizotypical traits ( 22 , 23 ). The PAS showed a score of 13/35, which places the patient in a slightly above average position (mean 7.8 ± 5.77) ( 24 ), highlighting the ease in incurring erroneous and abnormal perceptions of reality. The HPS evaluation instead showed a result clearly below average, with a score of 8/48 (mean 21.08 ± 8.19) ( 25 ).…”

The Sensitive Delusion of Reference is a clinical entity described by Ernst Kretschmer and never integrated into mainstream nosographic systems. It represents the possibility of developing psychosis starting from a personality characterized by sensitivity, scrupulousness, and fear of judgment of others. The presentation of the following clinical case highlights how the overlap between this clinical entity and mood disorders leads to characteristic psychopathology, which has not been sufficiently detailed. In particular, the delusions, which always starts from the idea of reference and the shame in the face of the judgment of others, takes on characteristics of guilt during the depressive phases and persecutory themes during the activation phases. This clinical observation, which obviously needs to be confirmed on a larger scale, encourages a renewed interest in the concept of Kretschmer's Sensitive Delusion of Reference and creates the possibility of intersecting multiple psychopathological levels, for a more complete perspective on the individual case.

“…Other questionnaires investigating similar psychological phenomena can be employed in the evaluation of patients with psychosis or UHR, most prominently the Perceptual Aberration Scale (Chapman et al ., 1978; Fornasari et al ., 2015) and the Referential Thinking Scale (Lenzenweger, Bennett & Lilenfeld, 1997); however, as the ASI's main scope is nominally Aberrant Salience, it is arguably the most indicated and up‐to‐date questionnaire to evaluate this construct. In fact, both the Perceptual Aberration Scale and the Referential Thinking Scale refer to a related but different construct, namely schizotypy (Coleman, Levy, Lenzenweger & Holzman, 1996; Lenzenweger et al ., 1997).…”

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.

“…Although UHR is associated with a wide range of clinical characteristics, including impaired role and social functioning (Addington et al, 2011;Velthorst et al, 2018), poor quality of life (QoL;Fusar-Poli et al, 2015), neurocognitive (Catalan et al, 2021) and social cognitive deficits (Van Donkersgoed et al, 2015), the relation to cognitive functions is under investigated. Perceptional Aberration Scale (PAS) has been applied as a useful self-report questionnaire (Fonseca-Pedrero et al, 2009) and is validated in large European samples (Fornasari, 2015;Meyer, 2001).…”

BackgroundUltra‐high risk (UHR) is considered a forerunner of psychosis, but most UHR individuals do not later convert, yet remain symptomatic, disabled and help‐seeking. Thus, there is an increased recognition of the UHR phenotype as a syndrome in itself, rather than merely a risk syndrome. It is therefore essential to investigate outcomes other than transition to psychosis. For this purpose, perceptual aberration appears to be a distinct, as well as a stable and less state‐specific vulnerability indicator. We aimed to investigate perceptual aberration and associations with functional, neuro and social cognitive risk factors in an UHR sample.MethodOne hundred and twenty UHR and 64 healthy controls were compared on levels of perceptual aberration using the perceptual aberration scale. We further investigated cross‐sectional associations between perceptual aberration and CAARMS (as a measure of subthreshold psychotic symptoms) and functional, neuro and social cognitive risk factors within the UHR using Spearmans ρ.ResultsPerceptual aberration was significantly higher in UHR than in healthy controls and was associated with social functioning, executive functioning, and emotion recognition.ConclusionOur findings are consistent with a view of perceptual aberration as a stable vulnerability indicator that varies little with clinical state.
