Background: Dopaminergic antipsychotics for schizophrenia have modest effects on symptoms and can cause important side effects. KarXT is an investigational drug for schizophrenia with a novel mechanism targeting muscarinic receptors that may limit these side effects.

Methods: We conducted a systematic review and Bayesian random-effects network meta-analyses of short-term RCTs (3-8 weeks) that enrolled adults with schizophrenia.

Objectives: To demonstrate how health technology assessment methods can be used to support Medicare's price negotiations for apixaban and rivaroxaban.

Methods: Following the statutory outline of evidence that will be considered by Medicare, we conducted a systematic literature review, network meta-analyses, and decision analyses to evaluate the health outcomes and costs associated with apixaban and rivaroxaban compared with warfarin and dabigatran for patients with nonvalvular atrial fibrillation. Our methods inform discussions about the therapeutic impact of apixaban and rivaroxaban and suggest price premiums above their therapeutic alternatives over a range of cost-effectiveness thresholds.

Objectives: The topic of diversity in clinical trials is rising to the forefront of many conversations in evidence-based medicine, and efforts are being made to improve the diversity of clinical trials. However, there is little uniformity in the methods used to evaluate these efforts. In this article, we describe our Clinical trial Diversity Rating (CDR) framework and the development process, including the broader considerations for evaluating the demographic diversity of clinical trials and their implications, and demonstrate its use through an illustrative example.

Background: Preventing or delaying the onset of psychosis requires identification of those at risk for developing psychosis. For predictive purposes, the prodrome - a constellation of symptoms which may occur before the onset of psychosis - has been increasingly recognized as having utility. However, it is unclear what proportion of patients experience a prodrome or how this varies based on the multiple definitions used.

Objectives: This study aimed to evaluate the diversity of clinical trials informing assessments conducted by the Institute for Clinical and Economic Review.

Methods: This was a cross-sectional study of pivotal trials included in completed Institute for Clinical and Economic Review assessments over 5 years (2017-2021). Representation of racial/ethnic minority groups, females, and older adults was compared with the disease-specific and US population, using a relative representation cutoff of 0.

Background: Metacognition refers to appraising one's thoughts and behaviours. Deficits in metacognition are associated with psychosis-spectrum experiences, such as hallucinations and delusions, in both clinical and non-clinical populations. Assessments of metacognitive function and abilities in clinical populations often vary in administration duration, and subjectivity of scores.

Background: Hallucinations have been linked to failures in metacognitive reflection suggesting an association between hallucinations and overestimation of performance, although the cross-sectional findings are inconsistent. This inconsistency may relate to the fluctuating hallucinatory experiences that are not captured in cross-sectional studies. Ecological Momentary Assessment (EMA) captures in-the-moment experiences over time so can identify causal relationships between variables such as the associations between metacognition and hallucinatory experience in daily life and overcome problems in cross-sectional designs.

In the study and treatment of psychosis, emotional intelligence (EI) and thinking styles are important patient characteristics for successful outcomes in clinical intervention. Anticipation of unpredictable stimuli (AUS) may be understood as an anomalous perception and anomalous cognition in which an individual supposedly senses and recognizes future stimuli in an unexpected way, also referred to as "hunches or premonitions." This examined the roles of EI and thinking styles in AUSs in convenience samples of healthy participants ( = 237) versus patients diagnosed with psychosis ( = 118).

Cannabis use is common in first-episode psychosis (FEP) but evidence is mixed about the extent to which cannabis use predicts symptoms and functional outcomes among those who seek treatment. This study sought to characterize cannabis use patterns and examine the relationship with clinical outcomes, including interactions with early intervention services (EIS). Data were drawn from the Recovery After an Initial Schizophrenia Episode-Early Treatment Program (RAISE-ETP) study including FEP individuals receiving treatment at sites randomized to provide either EIS (NAVIGATE) or community care (CC).

Background: Subclinical psychotic symptoms are common in the general population and are often benign. However, those that become distressing or persistent may increase risk for the development of a psychotic disorder. Cognitive models have proposed that certain appraisals of hallucinatory experiences can lead to delusional beliefs, particularly if an individual is experiencing negative mood.

To examine the feasibility, acceptability, and initial validity of using smartphone-based peer-supported ecological momentary assessment (EMA) as a tool to assess loneliness and functioning among adults with a serious mental illness diagnosis. Twenty-one adults with a diagnosis of a serious mental illness (i.e.

Background: Self-defining memories (SDMs) are important for identifying one's purpose in life, achieving goals, and overcoming challenging situations. Individual studies have demonstrated differences in the characteristics of SDMs between clinical and non-clinical populations. This systematic literature review aimed to summarise and compare SDM characteristics among those with mental, substance use, cognitive, neurodevelopmental, and physical health challenges.

Social cognition, including emotion perception, is impaired in people with serious mental illnesses (SMI), and is associated with cognitive and community functioning. Cognitive remediation can improve neurocognition, but the impact on emotion perception has been less well studied. The current study aimed to evaluate the efficacy of a cognitive remediation programme in improving emotion perception.

Background: Symptoms and functioning are critical dimensions in those with schizophrenia and are typically measured using validated conventional clinical assessments. Researchers and clinicians have begun to use real-time digital methods, such as ecological momentary assessment (EMA), to assess symptoms and functioning in the moment and outside of traditional hospital and laboratory settings, which may yield more naturalistic data. Although digital methods have advantages, it is unclear whether these momentary assessments capture core aspects of symptoms and functioning.

Background: Poor clinical insight has been commonly reported in those with First Episode Psychosis (FEP) and thought to be influenced by a range of factors, including neurocognition and symptoms. Clinical insight may be compromised as a result of alterations in higher-level reflective processes, such as metacognitive ability and cognitive insight.

Aims: To explore whether metacognitive ability and cognitive insight are associated with clinical insight while controlling for IQ, depression, and symptoms in FEP.

Background: Emerging data suggest cannabis use is a component cause of psychotic disorders; however, the sequence of processes accounting for this association is poorly understood. Some clues have come from studies in laboratory settings showing that acute cannabis intoxication is associated with subclinical hallucinations and delusional thinking, i.e.

The therapeutic alliance, or client-provider relationship, has been associated with better treatment engagement and outcomes for persons with schizophrenia-spectrum disorders (SSDs) and early psychosis in some studies, but not others. We conducted a meta-analysis of the research on alliance in SSDs and early psychosis across a range of interventions and outcomes. Parallel literature searches were conducted in PubMed and PsycINFO databases for articles between inception and 6/11/2020.

Background: Research has demonstrated that cognitive abilities predict work outcomes in people with psychosis. Cognitive Remediation Programs go some way in improving work outcomes, but individuals still experience difficulty maintaining employment. Metacognition has been demonstrated to predict work performance in individuals with schizophrenia, but this has not yet been applied to First Episode Psychosis (FEP).
