The Role of Negative Symptoms on the Continuum of Psychosis Risk as a Mediator of the Relationship Between Personality and Functioning in Individuals With Psychotic-Like Experiences.

Aim: Psychotic-like experiences (PLEs) may increase the risk of psychosis. Most of the research on PLEs focuses on their positive dimension-for example, hallucinatory-like experiences or delusion-like thoughts. Relatively little is known about the role of PLEs on the continuum of negative symptoms.

Cognitive Biases and Socio-Occupational Functioning Mediate the Relationship between Executive Functions and the Severity of Psychopathology among Young Adults with Psychotic-like Experiences: 1-Year Follow-Up Study.

The aim of this study was to investigate whether Trail Making Test (TMT) performance is associated with the severity of psychopathological symptoms related to psychosis among young adults with elevated level of psychotic-like experiences (PLEs), and whether this relationship is mediated by cognitive biases and socio-occupational functioning. A total of 187 subjects from a larger population of 6722 young adults participated in this 1-year follow-up study. The inclusion criteria were an elevated level of PLEs (the highest score of the Prodromal Questionnaire) and a lack of schizophrenia diagnosis.

Tinnitus characteristics in patients with hyperacusis and vertigo (including Ménière's disease) vs. hyperacusis alone.

Introduction And Objectives: To compare clinical and psychoacoustic tinnitus characteristics in patients with the comorbidity of hyperacusis, hyperacusis and vertigo, and with Ménière's disease (MD).

Materials And Methods: Three hundred and twenty-nine tinnitus patients underwent audiological and otoneurological evaluation. Records of 94 individuals younger than 65 years, 40 women and 54 men (mean age 41.

The effects of mindfulness-based training in virtual reality on psychotic symptoms, mood and cognitive functioning - a pilot study.

Objectives: Virtual reality (VR) is growing in popularity in treating various psychiatric disorders, including psychotic ones. However, no studies have been published on mindfulness interventions aided by virtual reality in psychotic patients to date.

Methods: 25 patients with schizophrenia or schizoaffective disorder were assessed at three time points with 4-week intervals using the six-item Positive and Negative Syndrome Scale (PANSS-6), Quick Inventory of Depressive Symptomatology (QIDS), Beck Depression Inventory (BDI), Beck Anxiety Inventory (BAI), State-Trait Anxiety Inventory (STAI), Perceived Stress Scale (PSS-10), and the Addenbrooke's Cognitive Examination III (ACE-III).

Application of 360° virtual reality videos in the assessment of paranoia in schizophrenia patients: a pilot study.

Objectives: Virtual Reality (VR) has been widely used in psychiatry, including psychotic disorders. The main advantage of VR is its high ecological validity and controllability of the virtual environment. Our main goal was to test whether, similarly to computer-generated VR, 360-degree videos are able to elicit a state of social paranoia in prone individuals.

On the relation of white matter brain abnormalities and the asociality symptoms in schizophrenia outpatients - a DTI study.

Recent MRI studies have shown that abnormal functional connections in schizophrenia coexist with subtle changes in the structure of axons in the brain. However, there is a discrepancy in the literature concerning the relationship between white matter abnormalities and the occurrence of negative psychopathological symptoms. In the present study, we investigate the relationship between the altered white matter structure and specific psychopathology symptoms, i.

Implementation of virtual reality (VR) in diagnostics and therapy of nonaffective psychoses.

Immersive virtual reality is a technology that allows the user to immerse in the virtual world in isolation from external stimuli. It enables the simulation of different social situations, often impossible to arrange in reality, with high control over the confounding variables. Thanks to the VR realism, the viewer of this reality behaves similarly and experiences similar emotions to those in natural conditions, which results in high ecological validity of this environment, making it useful for diagnostics and therapy.

Premorbid social relationships and the course of schizophrenia in a 20-year follow-up study.

Objectives: An important dimension indicating a growing risk of psychosis outbreak and its subsequent unfavorable course is deteriorating social functioning, especially the lack of sufficient social relationships. The aim of the study was to evaluate the association of the quality of social contacts and the scope of support system before the onset of the illness with treatment outcomes in clinical and social dimension in various time intervals of the 20-year illness course.

Methods: During the first hospitalization, an 80-person group living in Krakow and suffering from schizophrenia was selected, diagnosed according to DSM-IV-TR criteria and examined six times: at admission and discharge during first hospitalization, after 3, 7, 12 and 20 years.
