Cannabis use and cognitive biases in people with first-episode psychosis and their siblings.

Background: Cannabis use and familial vulnerability to psychosis have been associated with social cognition deficits. This study examined the potential relationship between cannabis use and cognitive biases underlying social cognition and functioning in patients with first episode psychosis (FEP), their siblings, and controls.

Methods: We analyzed a sample of 543 participants with FEP, 203 siblings, and 1168 controls from the EU-GEI study using a correlational design.

Adaptation and validation of the Adolescent Psychotic-like Symptom Screener (APSS-6) in Spain: evidence from adult population.

Background: Psychotic-like experiences are common in the general population and an important indicator of psychological vulnerability. One of the used instruments for their assessment is the Adolescent Psychotic-Like Symptom Screener (APSS). However, there are few studies on the APSS psychometric characteristics in different cultural contexts.

Attachment styles and associated psychosocial factors in patients at ultra-high risk for psychosis: A systematic review.

Background: Patients with an ultra-high risk of psychosis (UHR) are more likely to transition to psychosis. Attachment style has also been associated with psychosis and other symptoms.

Aims: To review attachment styles in UHR patients and to analyze related psychosocial factors.

Tobacco use in first-episode psychosis, a multinational EU-GEI study.

Background: Tobacco is a highly prevalent substance of abuse in patients with psychosis. Previous studies have reported an association between tobacco use and schizophrenia. The aim of this study was to analyze the relationship between tobacco use and first-episode psychosis (FEP), age at onset of psychosis, and specific diagnosis of psychosis.

A meta-analysis of cognitive interventions for patients with recent onset psychosis: are they effective for improving functioning?

The increasing popularity of cognitive interventions for patients with psychosis calls for further exploration on how these interventions may benefit functional outcomes. We conducted a meta-analysis of randomized controlled trials (RCTs) to examine the effectiveness of cognitive interventions (i.e.

Efficacy of technology-based interventions in psychosis: a systematic review and network meta-analysis.

Background: Technology-based interventions (TBIs) are a useful approach when attempting to provide therapy to more patients with psychosis.

Methods: Randomized controlled trials of outcomes of TBIs face-to-face interventions in psychosis were identified in a systematic search conducted in PubMed/Ovid MEDLINE. Data were extracted independently by two researchers, and standardized mean changes were pooled using a three-level model and network meta-analysis.

[Psychopathological symptoms during Covid-19 quarantine in spanish general population: a preliminary analysis based on sociodemographic and occupational-contextual factors.].

Objective: Coronavirus (COVID-19) pandemic disease forced different countries to adopt quarantine measures. These actions could have an impact on mental health in the general population. The objective of this study was to analyze the differences in psychopathological symptoms shown by Spanish general population during the COVID-19 quarantine based on sociodemographic, occupational and environmental-contextual variables.

Cannabis use and nonuse in patients with first-episode psychosis: A systematic review and meta-analysis of studies comparing neurocognitive functioning.

Background: The implications of cannabis use in the onset of early psychosis and the severity of psychotic symptoms have resulted in a proliferation of studies on this issue. However, few have examined the effects of cannabis use on the cognitive symptoms of psychosis (i.e.

A systematic review of online interventions for families of patients with severe mental disorders.

Background: Several studies show the effectiveness of face-to-face interventions with families in improving the prognosis of patients with severe psychiatric disorders and their relatives; however, the effectiveness of online interventions is poorly understood. The current study aims to provide an overview of evidence for the effectiveness of online treatments (web/app) for patients with severe psychiatric disorders and their families.

Method: We performed a systematic review of online treatments for informal family caregivers of patients with a severe psychiatric disorder.

Neuropsychological, clinical and environmental predictors of severe mental disorders in offspring of patients with schizophrenia.

Offspring of individuals with schizophrenia (SZCOff) are at an increased risk for this disorder. Neuropsychological decline is a core feature of the disorder and researchers have reported increasing impairments in cognition during the prodromal phase in high-risk adolescents. Additionally, factors like the presence of prodromal symptoms or specific behavioral patterns could predict, together with neurocognitive functioning, the risk of conversion to severe mental disorders in SCZOff.

Mobile App-Based Intervention for Adolescents With First-Episode Psychosis: Study Protocol for a Pilot Randomized Controlled Trial.

Previous studies have shown an improvement in the access to treatment for patients with first-episode psychosis (FEP), specifically young patients, through mobile app-based interventions. The aim of this study is to test the effectiveness of a mobile app-based intervention to improve community functioning in adolescents with FEP. Mobile app-based interventions could increase quality of life and disease awareness, which improve adherence to treatment and reduce the frequency of relapses and rehospitalizations in adolescents with FEP.

Smoking does not impact social and non-social cognition in patients with first episode psychosis.

Background: Many studies having shown significant improvements in non-social and social cognitive performance in smoking FEP patients compared to non-smoking FEP patients. The findings are controversial. This study analyzed the effects of tobacco use on non-social and social cognitive function in a large group of FEP patients and a matched healthy control group.
