The relationship between childhood trauma, psychotic symptoms, and cognitive schemas in patients with schizophrenia, their siblings, and healthy controls: results from the EU-GEI study
Ucok A, Noyan H, Guloksuz S, Saka M, Alptekin K, Atbasoglu C, et al.
Psychol Med . 2024 Apr; 54(10):2414-2425. PMID: 38606591
Background: The relationship between childhood trauma (CT) and psychotic symptoms in patients with schizophrenia (SCZ), and subthreshold psychotic experiences in non-clinical populations is well-established. However, little is known about the...

Examining the association between exposome score for schizophrenia and cognition in schizophrenia, siblings, and healthy controls: Results from the EUGEI study
Fusar-Poli L, Prachason T, Erzin G, Pries L, Brondino N, Politi P, et al.
Psychiatry Res . 2023 Apr; 323:115184. PMID: 37015164
Background: People with schizophrenia spectrum disorders (SSD) frequently present cognitive impairments. Here, we investigated whether the exposome score for schizophrenia (ES-SCZ) - a cumulative environmental exposure score - was associated...

The association between cannabis use and facial emotion recognition in schizophrenia, siblings, and healthy controls: Results from the EUGEI study
Fusar-Poli L, Pries L, van Os J, Radhakrishnan R, Pence A, Erzin G, et al.
Eur Neuropsychopharmacol . 2022 Sep; 63:47-59. PMID: 36055075
Schizophrenia is frequently accompanied with social cognitive disturbances. Cannabis represents one established environmental factor associated with the onset and progression of schizophrenia. The present cross-sectional study aimed to investigate the...

Examining facial emotion recognition as an intermediate phenotype for psychosis: Findings from the EUGEI study
Fusar-Poli L, Pries L, van Os J, Erzin G, Delespaul P, Kenis G, et al.
Prog Neuropsychopharmacol Biol Psychiatry . 2021 Sep; 113:110440. PMID: 34536513
Background: Social cognition impairments, such as facial emotion recognition (FER), have been acknowledged since the earliest description of schizophrenia. Here, we tested FER as an intermediate phenotype for psychosis using...

Examining the association between exposome score for schizophrenia and functioning in schizophrenia, siblings, and healthy controls: Results from the EUGEI study
Erzin G, Pries L, van Os J, Fusar-Poli L, Delespaul P, Kenis G, et al.
Eur Psychiatry . 2021 Mar; 64(1):e25. PMID: 33736735
Background: A cumulative environmental exposure score for schizophrenia (exposome score for schizophrenia [ES-SCZ]) may provide potential utility for risk stratification and outcome prediction. Here, we investigated whether ES-SCZ was associated...

Cognitive functioning throughout adulthood and illness stages in individuals with psychotic disorders and their unaffected siblings
Velthorst E, Mollon J, Murray R, de Haan L, Germeys I, Glahn D, et al.
Mol Psychiatry . 2021 Jan; 26(8):4529-4543. PMID: 33414498
Important questions remain about the profile of cognitive impairment in psychotic disorders across adulthood and illness stages. The age-associated profile of familial impairments also remains unclear, as well as the...

Evidence, and replication thereof, that molecular-genetic and environmental risks for psychosis impact through an affective pathway
van Os J, Pries L, Have M, de Graaf R, van Dorsselaer S, Delespaul P, et al.
Psychol Med . 2020 Oct; 52(10):1910-1922. PMID: 33070791
Background: There is evidence that environmental and genetic risk factors for schizophrenia spectrum disorders are transdiagnostic and mediated in part through a generic pathway of affective dysregulation. Methods: We analysed...
8.
A replication study of JTC bias, genetic liability for psychosis and delusional ideation
Henquet C, van Os J, Pries L, Rauschenberg C, Delespaul P, Kenis G, et al.
Psychol Med . 2020 Oct; 52(9):1777-1783. PMID: 33046166
Background: This study attempted to replicate whether a bias in probabilistic reasoning, or 'jumping to conclusions'(JTC) bias is associated with being a sibling of a patient with schizophrenia spectrum disorder;...

White Noise Speech Illusions: A Trait-Dependent Risk Marker for Psychotic Disorder?
Schepers E, Lousberg R, Guloksuz S, Pries L, Delespaul P, Kenis G, et al.
Front Psychiatry . 2019 Oct; 10:676. PMID: 31607966
White noise speech illusions index liability for psychotic disorder in case-control comparisons. In the current study, we examined i) the rate of white noise speech illusions in siblings of patients...

Estimating Exposome Score for Schizophrenia Using Predictive Modeling Approach in Two Independent Samples: The Results From the EUGEI Study
Pries L, Lage-Castellanos A, Delespaul P, Kenis G, Luykx J, Lin B, et al.
Schizophr Bull . 2019 Sep; 45(5):960-965. PMID: 31508804
Exposures constitute a dense network of the environment: exposome. Here, we argue for embracing the exposome paradigm to investigate the sum of nongenetic "risk" and show how predictive modeling approaches...
