Virtual Reality Interventions and Psychosocial Functioning in Schizophrenia Spectrum Disorders: A Systematic Review.

Objective: The objective of this study is to evaluate the effectiveness of virtual reality (VR) intervention programs that aim to improve psychosocial functioning in schizophrenia spectrum disorders and evaluate the quality assessment of these studies.

Methods: PRISMA (Preferred Reporting Items for Systematic reviews and Meta-Analyses) guideline was followed to conduct this systematic review. The literature search was performed in Web of Science (WoS) and PubMed, by two independent researchers on two occasions, on 1 March 2023 and 20 August 2023.

Reliability and validity study of the Turkish version of the Schizophrenia Cognition Rating Scale (SCoRS-TR).

Background: Schizophrenia is characterized by significant dysfunction in cognitive domains. Despite its crucial role in prognosis, evaluating neurocognitive impairments is challenging in outpatient settings because of the time-consuming nature of neurocognitive assessments. SCoRS "Schizophrenia Cognition Rating Scale" is a scale that provides brief cognitive evaluation.

The impact of affective and negative symptoms on the development of psychosis in a six-year follow-up of a community-based population.

Purpose: The Clinical High Risk (CHR) concept has a limited transition risk to psychotic disorders (PD). This study investigates the association between affective and negative symptoms, currently not included in the CHR concept, and the risk of transition to PD in a community-based population of 2185 participants in Turkey.

Methods: Participants were assessed twice over six years using a multistage sampling technique.

Relationship between the Use of Mobile Applications and Social Functioning in Patients with Schizophrenia.

Objectives: The aim of this study is to examine the prevalence of digital technology tool use in individuals with schizophrenia or schizoaffective disorder in Turkey, as well as evaluating the association between the use and psychosocial functionality and clinical symptoms.

Method: Data were collected from 100 patients who were diagnosed with schizophrenia or schizoaffective disorder based on the DSM-5 criteria. The use of technology was evaluated with a questionnaire developed for this study.

Early and late contingent negative variation (CNV) reflect different aspects of deficits in schizophrenia.

Abnormal reward processing and psychomotor slowing are well-known in schizophrenia (SZ). As a slow frontocentral potential, contingent negative variation (CNV) is associated with anticipatory attention, motivation and motor planning. The present study aims to evaluate the early and late amplitude and latencies of CNV in patients with SZ compared to healthy controls during a reward processing task and to show its association with clinical symptoms.
