Paranoid thinking, that others are hostile, can be seen even in the general population. Paranoia is considered the expectation that others are competitors who aim to maximize the differences in payoff...
Cognitive theories assume an imbalance of intuitive and analytical reasoning in paranoid ideation. The argumentative theory of reasoning offers an approach on the primary function of reasoning and its...
327 participants completed the Social Network Index (SNI), the Paranoia Checklist (PCL), and the Cognitive Reflection Test-2 (CRT2). Moreover, preference and frequency of discussions were assessed. In...
The discussion group showed lower distorted reflective reasoning than the control group. Discussion preference and/or frequency was associated with frequency and disturbance of paranoid thoughts, as w...
Due to the online format environmental factors could not be held constant and no intrasubject comparison of the CRT2 could be computed in the trial. Furthermore, the sample mainly consisted of psychol...
The results contribute to the understanding of distorted reflective reasoning and provides preliminary evidence that the argumentative theory of reasoning may offer a promising perspective for delusio...
Schizophrenia spectrum disorders cause suffering for patients, relatives, and the surrounding society. Paranoid ideations, encompassing ideas of social reference and manifest persecutory delusions, ar...
This study is a randomized, assessor-blinded parallel-groups multi-center superiority clinical trial, fulfilling the CONSORT criteria for non-pharmacological treatment. A total of 256 patients diagnos...
The trial will elucidate whether VR-CBT can enhance therapy efficacy for paranoid ideations. Additionally, Trial findings will provide evidence on the effectiveness and cost-effectiveness of VR-CBT fo...

Paranoia is common in clinical and nonclinical populations, consistent with continuum models of psychosis. A number of experimental studies have been conducted that attempt to induce, manipulate or me...
Virtual reality (VR) is increasingly used in the study and treatment of paranoia. This is based on the finding that people who mistakenly perceive hostile intent from other people also perceive simila...
Psychotic experiences have been associated with distortions in affective functioning, including aberrancies in affect dynamics. However, it remains unclear whether the two principal symptom dimensions...
Persecutory ideas are highly frequent in psychotic disorders and particularly in schizophrenia. Although several measures exist to assess persecutory ideas in both clinical and non-clinical samples, t...
100 individuals with schizophrenia and 72 non-clinical controls were recruited. We used the GPTS-8, a brief 8-item version of the R-GPTS recently developed and validated in the French general populati...
Confirmatory factor analysis supported the original two-factor structure (social reference and persecution subscales) of the GPTS-8. The GPTS-8 was positively and moderately correlated with the Positi...
The French GPTS 8-item brief scale-8 retains the psychometric strengths of the R-GPTS in schizophrenia with relevant clinical validity. The GPTS-8 can consequently be used as a short and quick measure...
Paranoia is a common and impairing psychosis symptom, which exists along a severity continuum that extends into the general population. Individuals at clinical high-risk for psychosis (CHR) frequently...
Participants were CHR individuals (n = 103), mixed clinical controls (n = 80), and healthy controls (n = 71) who completed self-report and interview measures. Confirmatory factor analysis (CFA), psych...
CFA replicated a two-factor structure for the RGPTS and the associated reference and persecution scales were reliable. CHR individuals scored significantly higher on both reference and persecution, re...
These results demonstrate the reliability and validity of the RGPTS, though its scales related more weakly to severity in CHR individuals. The RGPTS may be useful in future work aiming to develop symp...
Paranoia is the belief that others intend you harm. It is related to conspiracy theories, wherein those others represent an organized faction, coordinating the harm against self and others, and violat...
Cognitive Bias Modification for paranoia (CBM-pa) is a novel, theory-driven psychological intervention targeting the biased interpretation of emotional ambiguity associated with paranoia. Study object...
In a double-blind randomised controlled trial, sixty-three outpatients with clinically significant paranoia were randomised to either CBM-pa or an active control (text reading) between April 2016 and ...
A total of 122 patients were screened and 63 were randomised. The recruitment rate was 51.2%, with few dropouts (four out of 63) and follow-up rates were 90.5% (1-month) and 93.7% (3-months). Each ses...
CBM-pa is feasible for patients with paranoia. A fully powered randomised control trial is warranted....
