Diverse models have been developed to predict psychosis in patients with clinical high-risk (CHR) states. Whether prediction can be improved by efficiently combining and biological broadening the risk spectrum young depressive syndromes remains unclear.To evaluate whether transition predicted CHR or recent-onset depression (ROD) using multimodal machine learning that optimally integrates neurocognitive data, structural magnetic resonance imaging (sMRI), polygenic scores (PRS) for...

Early detection of psychosis is an important topic in psychiatry. Yet, there limited information on the prevalence and clinical significance high-risk symptoms children adolescents as compared to adults. We examined ultra-high-risk (UHR) criteria a sample individuals aged 8-40 years from general population Canton Bern, Switzerland, enrolled June 2011 May 2014. The current presence attenuated psychotic (APS) brief intermittent (BLIPS) fulfillment onset/worsening frequency requirements for...

Impaired cognition is an important dimension in psychosis and its at-risk states. Research on the value of impaired for prediction samples, however, mainly relies study-specific sample means neurocognitive tests, which unlike widely available general test norms are difficult to translate into clinical practice. The aim this study was explore combined predictive criteria deficits according with a risk stratification approach.Potential predictors (neurocognitive criteria) over 24 months were...

An efficient indicated prevention of psychotic disorders requires valid risk criteria that work in both clinical and community samples. Yet, ultra-high basic symptom were recently recommended for use samples only. Their the was discouraged lack knowledge about their prevalence, relevance factors non-clinical, settings when validly assessed with same instruments used clinic.Using semi-structured telephone interviews established psychosis-risk instruments, we studied prevalence symptoms...

Abstract Aims Clinical high-risk for psychosis (CHR-P) states exhibit diverse clinical presentations, prompting a shift towards broader outcome assessments beyond manifestation. To elucidate more uniform profiles and their trajectories, we investigated CHR-P in community sample. Methods Participants ( N = 829; baseline age: 16–40 years) comprised individuals from Swiss sample who were followed up over roughly 3 years. latent class analysis was applied to symptom data at follow-up, classes...

Abstract Background Beyond psychosis prediction, clinical high-risk (CHR-P) symptoms show relevance by their association with functional impairments and psychopathology, including personality pathology. Impaired functioning is prioritized in recent dimensional disorder models (DSM-5, ICD-11), yet underexplored CHR-P, as are associations cognitive biases, which early studies indicate possibly linking CHR-P-symptoms Methods A community sample ( N = 444, 17–60 years, 61.8% female) was assessed...

Abstract Background This study aimed to deepen the understanding of psychological mechanisms underlying formation and maintenance clinical high-risk symptoms for psychosis (CHR-P) in real-life contexts. Specifically, it examined whether (i) momentary feelings stress increase frequency CHR-P symptoms, or conversely, (ii) intensity stress. Additionally, potential moderators relationship between were explored. Methods Using Ecological Momentary Assessment, 79 patients (age: 11–36; 50.6% female)...
