Psychotic-like experiences (PLEs) may reflect elevated risk for serious mental illness, including psychosis. Although some studies report an association between PLEs and increased service utilization, there is evidence of unmet need among individuals with PLEs, with few studies exploring the relation between PLEs and intent to seek treatment. Characterizing factors that underlie intent to seek treatment in individuals not otherwise engaged in treatment may assist in determining the role of PLEs and future intentions, and help prioritize symptoms of greatest significance.

Background: Since its inception, research in the clinical high-risk (CHR) phase of psychosis has included identifying and exploring the impact of relevant socio-demographic factors. Employing a narrative review approach and highlighting work from the United States, sociocultural and contextual factors potentially affecting the screening, assessment, and service utilization of youth at CHR were reviewed from the current literature.

Results: Existing literature suggests that contextual factors impact the predictive performance of widely used psychosis-risk screening tools and may introduce systemic bias and challenges to differential diagnosis in clinical assessment.

Evidence suggests dysregulation of the salience network in individuals with psychosis, but few studies have examined the intersection of stress exposure and affective distress with prediction error (PE) signals among youth at clinical high-risk (CHR). Here, 26 individuals at CHR and 19 healthy volunteers (HVs) completed a monetary incentive delay task in conjunction with fMRI. We compared these groups on the amplitudes of neural responses to surprising outcomes-PEs without respect to their valence-across the whole brain and in two regions of interest, the anterior insula and amygdala.

Evidence supports the use of brief psychosis-spectrum screening tools for identifying individuals at an increased risk of developing a psychotic disorder. Screening has not been well studied in general mental health settings that serve young adults in the age range associated with highest risk for psychosis. This study explored the feasibility of psychosis-risk screening and assessment among help-seeking students at a university counseling center.

Resilience research has documented the ability to cope with traumatic and stressful situations and/or retain functioning given certain risk factors in the context of psychosis. In this study, we conducted the first systematic review of the literature on psychosis-like experiences (PLEs) and resilience. Fifteen articles (from 11 unique study samples) from 10 countries were included in this systematic review, with a total of 11,937 unique study participants.

Subjective quality of life can be compromised in individuals with psychosis-risk symptoms, with poorer quality of life being associated with worse functioning and later transition to psychosis. Individuals who experience psychosis-related symptoms also tend to endorse more internalized (or self-) mental health stigma when compared to controls, potentially contributing to delays in seeking treatment and increased duration of untreated psychosis, as well as interfering with treatment engagement and retention in those already receiving care. Despite these findings, and the growing recognition for prevention in earlier phases of psychotic illness, few studies have examined the relation between psychosis-risk symptoms, internalized stigma, and subjective quality of life in a younger, help-seeking sample.

Extensive research has demonstrated racial disparities, particularly among Black individuals, in both presentation and course of psychosis spectrum disorders. Few studies, however, have examined racial differences in the clinical high-risk (CHR) phase of illness. It is unclear if functional deficits seen in association with CHR symptoms generalize to marginalized racial groups, or whether race may play a role in the link between symptoms and functioning.

Racial inequities in mental health care utilization (MHCU) are well documented. Marginalized racial groups are more likely to report psychosis-like experiences (PLEs) and are at elevated risk for racial discrimination and trauma, impacting PLE severity. Little is known about how factors associated with race impact treatment seeking among individuals reporting PLEs.

Experiencing psychosis-spectrum symptoms is challenging to youth. Among many difficulties, internalized mental health stigma-the internalization of negative stereotypes-can lead to shame and withdrawal. The objective of this study was to better understand the correlates of internalized stigma among a clinical sample of youth with psychosis-spectrum symptoms.

Early detection and prevention of psychosis has become an international priority. Much of this work has focused on youth presenting with attenuated symptoms of psychosis-those at Clinical High Risk for psychosis (CHR)-given their elevated probability of developing the full disorder in subsequent years. Individuals at CHR may be prone to exacerbated psychological distress during the COVID-19 pandemic and its subsequent physical isolation measures, due to heightened stress sensitivity and comorbid mental health problems.

Dysfunction in the neural circuits underlying salience signaling is implicated in symptoms of psychosis and may predict conversion to a psychotic disorder in youth at clinical high risk (CHR) for psychosis. Additionally, negative symptom severity, including consummatory and anticipatory aspects of anhedonia, may predict functional outcome in individuals with schizophrenia-spectrum disorders. However, it is unclear whether anhedonia is related to the ability to attribute incentive salience to stimuli (through reinforcement learning [RL]) and whether measures of anhedonia and RL predict functional outcome in a younger, help-seeking population.

Aim: Outcomes for individuals with psychotic disorders can be improved through early intervention services; however, identification continues to be a major problem in connecting individuals with these services. Social workers form a vast majority of the human service and mental health workforce in the United States and therefore have the potential to play a unique role in identifying and referring those who may benefit from specialty early intervention services.

Methods: The current article describes the methodological design, implementation, and participant recruitment procedures of a large-scale, web-based training program for social workers promoting identification and referral of individuals with emerging symptoms of a mental illness with psychosis in the context of a randomized clinical trial.

Aim: Early psychosis is typically operationalized as a categorical construct by dividing people into one of three diagnostic statuses: low-risk, clinical high-risk, and first episode psychosis. We empirically assess whether an alternative dimensional approach focused on observed symptom severity may be more desirable for clinical and research purposes.

Methods: Participants were 152 help-seeking youths ages 12-22 years old.

Objective: D-cycloserine (DCS) promotes consolidation of extinction learning. This study extends earlier work by examining whether DCS can enhance cognitive behavioral therapy (CBT) for delusions.

Methods: Adults reporting moderate or greater delusions were randomly assigned to receive 50 mg of DCS or placebo prior to 10 weekly CBT sessions.

Aim: Evidence supports the use of brief psychosis-spectrum screeners for identifying individuals at risk for psychosis. Screening has not been well-studied in help-seeking college samples. This study investigated the use of the Behavior Assessment System for Children, Second Edition (BASC-2) Atypicality Scale as a psychosis-spectrum screening tool within a university counselling centre.

Aim: Positive symptoms are a critical dimension of psychopathology in psychotic disorders and are used as a criterion for diagnosis across the psychosis continuum. Although initially considered as one dimension, there is evidence for multidimensionality within positive symptoms. The positive symptom structure has not been examined in individuals at clinical high risk (CHR) for psychosis.

Introduction: Contextual factors representing chronic stressors, such as neighborhood crime characteristics, have been repeatedly linked to compromised mental and physical health, and may contribute to the pathologizing of normative/non-clinical experiences. However, the impact of such structural factors has seldom been incorporated in Clinical High Risk (CHR) for psychosis research. Understanding how context can influence the presence or severity of symptoms such as suspiciousness/paranoia may have important relevance for promoting valid and reliable assessment, as well as for understanding ways in which environment may be related to illness development and expression.

Recovery-oriented treatment for youth with psychosis goes beyond a symptom and deficit-amelioration model, promoting engagement and functioning within the community. Given the challenges young people with psychosis face, early psychosis treatment programs often integrate rehabilitative components targeting functional outcomes. The current article reviews 4 community rehabilitation programs in early psychosis: care coordination, cognitive rehabilitation, supported education and employment, and peer support.

Objective: Self-report screening instruments for emerging psychosis have the potential to improve early detection efforts by increasing the number of true positives among persons deemed to be at "clinical high risk" of the disorder, but their practical utility depends on their validity across race. This study sought to examine whether a commonly used self-report screening tool for psychosis risk performed equally among black and white youths in its ability to predict clinical high-risk status.

Methods: Black (N=58) and white (N=50) help-seeking individuals ages 12-25 (61% female) were assessed with the Prime Screen and the Structured Interview for Psychosis-Risk Syndromes (SIPS).

Background: Current methods to identify people with psychosis risk involve administration of specialized tools such as the Structured Interview for Psychosis-Risk Syndromes (SIPS), but these methods have not been widely adopted. Validation of a more multipurpose assessment tool-such as the Kiddie Schedule for Affective Disorders and Schizophrenia (K-SADS)-may increase the scope of identification efforts.

Methods: We assessed the correspondence between SIPS-determined clinical high risk/early psychosis (CHR/early psychosis) status and K-SADS psychosis screen (child and parent reports and their combination) in a sample of 147 help-seeking individuals aged 12-25.

Abnormal reward processing is thought to play an important role in the development of psychosis, but relatively few studies have examined reward prediction errors, reinforcement learning (RL), and the reward circuitry that subserves these interconnected processes among individuals at clinical high-risk (CHR) for the disorder. Here, we present behavioral and functional neuroimaging results of two experimental tasks designed to measure overlapping aspects of reward processing among individuals at CHR (n = 22) and healthy controls (n = 19). We found no group differences in response times to positive, negative, or neutral outcome-signaling cues, and no significant differences in brain activation during reward anticipation or receipt.

Psychosis-like experiences are present in the general population and may indicate risk for more severe forms of psychosis. They are associated with cognitive impairments, potentially impacting ability to accurately complete certain self-report measures. This study investigated whether the presence of psychosis-like experiences was associated with impairments in retrospective reports of physical activity, a measure salient to this population, by comparing post-study questionnaire data on activity level with reports of activity contemporaneously collected through ecological momentary assessment (EMA).
