Abstract
BACKGROUND AND HYPOTHESIS Psychotic-like experiences (PLEs) are prevalent in the general population and, because they represent a lower end of the psychosis vulnerability spectrum, may be useful in informing mechanistic understanding. Although it is well-understood that motor signs characterize formal psychotic disorders, the developmental trajectory of these features and their relationships with PLEs are less well-understood. STUDY DESIGN Data from 7559 adolescents and young adults (age 11-21) in the Philadelphia Neurodevelopmental Cohort were used to investigate whether early-life milestone-attainment delays relate to current adolescent sensorimotor functioning and positive and negative PLEs. Current sensorimotor functioning was assessed using the Computerized Finger Tapping task (assessing motor slowing) and Mouse Practice task (assessing sensorimotor planning). STUDY RESULTS Early developmental abnormalities were related to current adolescent-aged motor slowing (t(7415.3) = -7.74, corrected-P < .001) and impaired sensorimotor planning (t(7502.5) = 5.57, corrected-P < .001). There was a significant interaction between developmental delays and current sensorimotor functioning on positive and negative PLEs (t = 1.67-4.51), such that individuals with early developmental delays had a stronger positive relationship between sensorimotor dysfunction and PLEs. Importantly, interaction models were significantly better at explaining current PLEs than those treating early and current sensorimotor dysfunction independently (χ2 = 4.89-20.34). CONCLUSIONS These findings suggest a relationship between early developmental delays and current sensorimotor functioning in psychosis proneness and inform an understanding of heterotypic continuity as well as a neurodevelopmental perspective of motor circuits. Furthermore, results indicate that motor signs are a clear factor in the psychosis continuum, suggesting that they may represent a core feature of psychosis vulnerability.

Abstract
BackgroundSince 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.ResultsExisting 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. Factors reviewed include racialized identity, discrimination, neighborhood context, trauma, immigration status, gender identity, sexual orientation, and age. Furthermore, racialized identity and traumatic experiences appear related to symptom severity and service utilization among this population.ConclusionsCollectively, a growing body of research from the United States and beyond suggests that considering context in psychosis-risk assessment can provide a more accurate appraisal of the nature of risk for psychosis, render more accurate results improving the field's prediction of conversion to psychosis, and enhance our understanding of psychosis-risk trajectories. More work is needed in the U.S. and across the globe to uncover how structural racism and systemic biases impact screening, assessment, treatment, and clinical and functional outcomes for those at CHR.

Abstract
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. In a sample of youth at CHR (N = 46), the present study examined the effect of race (Black and White represented in this sample) on the relation between CHR symptoms and social/role functioning. Race had a moderating effect on the relation between CHR symptoms and social functioning for total positive symptom score (p < .04, f2 = 0.10). Although positive symptoms were associated with worse social functioning for White participants, no association was found for Black participants. Follow up analyses indicated suspiciousness was a statistically significant predictor of social functioning for White participants but was unrelated to functioning for Black participants. Results may be indicative of phenomenon experienced by individuals within racial minority groups (e.g., "healthy suspiciousness") or potential measurement validity concerns. Findings further the understanding of racial differences in the CHR phase of illness among White and Black youth and highlight limitations of the existing CHR literature and assessment tools for diverse youth.

Abstract
AIMS Psychotic experiences differ with age. It is currently unknown whether there were specific patterns and associations between the presentation of psychotic experiences and age. This study aimed to explore age-related differences (15-45 years) in self-reported psychotic experiences in a large-scale clinical population. METHODS A total of 2542 consecutive new patients aged 15-45 years were recruited on their first visit to the Shanghai Mental Health Center and screened with the PRIME Screen-Revised (PS-R). According to the clinical diagnostic information of patients from their outpatient medical records compiled by their clinicians, four diagnostic categories were applied: 1) psychotic disorder; 2) mood disorder; 3) anxiety disorder and 4) others. RESULTS The PS-R scores of self-reported psychotic experiences declined with age, except for two age ranges: ≤18 years for overall sample (≤18 vs. 19-34 years: t = 5.531, df = 2202, p < .001) and 37-40 years for female sample (37-40 vs. >40 years: t = 1.985, df = 138, p = .049), which showed upward trends, contrary to those of others. There were no significant differences in self-reported psychotic experiences between age groups in patients with psychotic disorders, while significant age differences were found in all nonpsychotic patients. CONCLUSION These findings support the view that frequent PS-R screening demonstrated that psychotic experiences decline with age in the clinical population. Early detection of psychosis should focus on not only adolescents but also women aged >36 years.

Abstract
Prevention and early intervention programs have been initiated worldwide to serve youth at Clinical High Risk for Psychosis (CHR-P), who are adolescents and young adults experiencing subclinical psychosis and functional impairment. The primary goals of these efforts are to prevent or mitigate the onset of clinical psychosis, while also treating comorbid issues. It is important to consider issues of diversity, equity, and inclusion in CHR-P work, especially as these programs continue to proliferate around the world. Further, there is a long history in psychiatry of misdiagnosing and mistreating psychosis in individuals from racial and ethnic minority groups. Although there have been significant developments in early intervention psychosis work, there is evidence that marginalized groups are underserved by current CHR-P screening and intervention efforts. These issues are compounded by the contexts of continued social marginalization and significant mental health disparities in general child/adolescent services. Within this narrative review and call to action, we use an intersectional and minority stress lens to review and discuss current issues related to equity in CHR-P services, offer evidence-based recommendations, and propose next steps. In particular, our intersectional and minority stress lenses incorporate perspectives for a range of marginalized and underserved identities related to race, ethnicity, and culture; faith; immigration status; geography/residence; gender identity; sexual orientation; socioeconomic status/class; and ability status.

Abstract
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. Structured interview for psychosis risk syndromes interviews were used to obtain dimensional psychosis symptom severity ratings, and to classify participants by categorical psychosis risk status. Twenty-five participants were classified as having a diagnosable psychotic disorder, 52 participants as clinical high-risk, and 75 participants as help-seeking controls. We assessed the relation between categorical and dimensional measurements of psychosis severity, and then compared categorical versus dimensional psychosis severity in their ability to predict social and role functioning. RESULTS On average, dimensional psychosis symptom severity increased along with categorical risk status (help-seeking control < clinical high-risk < diagnosable psychotic disorder). There was, however, considerable overlap between categories, with people at clinical high-risk being particularly hard to distinguish from people with diagnosable psychotic disorders on the basis of symptom severity. Dimensional symptom severity was more predictive of functioning than categorical risk status. CONCLUSIONS Categorical risk status and psychosis symptom severity are related but not interchangeable, and dimensional models of psychosis may be more predictive of functional outcomes. Adopting a dimensional rather than categorical approach to the psychosis risk spectrum may facilitate better predictive models and a richer theoretical understanding of early psychosis.

Abstract
Based on the assumption of a universal neurodevelopmental model of psychosis, especially of the schizophrenia spectrum, the diagnosis (and treatment) of psychosis in minors commonly follows those in adults. Yet, as our review demonstrates, recent years have seen an emergence of studies of minors indicating that developmental aspects may play a crucial role in the prevalence and appraisal of diagnostically relevant positive psychotic symptoms in their full-blown and subthreshold forms, including neurobiogenetic and other risk factors, such as migration. Thus, caution is advised to not overpathologize potentially transient and clinically irrelevant occurrence of (subthreshold) positive psychotic symptoms in the diagnosis and treatment of psychotic disorders and their clinical high-risk states in minors. More studies on developmental aspects are urgently needed.

Abstract
AIM Early psychosocial treatment for psychosis-spectrum symptoms has been linked to positive outcomes, whereas delayed treatment is associated with poorer prognosis. Thus, there is a critical need to bolster psychotherapy engagement efforts, particularly among high-risk groups and during high-risk periods, in order to maximize recovery. This study explores the relation between psychosis-spectrum symptoms and psychotherapy readiness among psychiatrically hospitalized adolescents, a foundational step for developing more effective psychotherapy engagement approaches for this population. METHODS Adolescents (n = 704; 12-18 years) who were admitted to a psychiatric inpatient unit completed the Readiness for Psychotherapy Index (RPI), a psychosis-spectrum questionnaire (PRIME Screen), and a brief diagnostic interview at intake. Correlational patterns and regression analyses were used to explore associations between variables. RESULTS The PRIME Screen was negatively associated with the RPI Openness subscale and positively associated with the Distress subscale, beyond the effects of demographics (ie, age, sex, race) and psychiatric diagnoses. CONCLUSIONS Results indicate that the RPI probes multiple facets of psychotherapy readiness that have unique associations with psychosis-spectrum experiences. Adolescents with higher PRIME scores endorsed greater mental health-related distress and lower levels of openness to psychotherapy. These psychotherapy readiness factors warrant further exploration, as they may be significant barriers or facilitators to engaging adolescents with psychosis-spectrum symptoms in much needed early treatment services.

Abstract
Schizophrenia and other psychotic disorders are serious psychiatric disorders that are associated with substantial societal, family, and individual costs/distress. Evidence suggests that early intervention can improve prognostic outcomes; therefore, it is essential to accurately identify those at risk for psychosis before full psychotic symptoms emerge. The purpose of our study is to develop a brief, valid screening questionnaire to identify individuals at risk for psychosis in non-clinical populations across 3 large, community catchment areas with diverse populations. This is a needed study, as the current screening tools for at-risk psychotic populations in the US have been validated only in clinical and/or treatment seeking samples, which are not likely to generalize beyond these specialized settings. The specific aims are as follows: (1) to determine norms and prevalence rates of attenuated positive psychotic symptoms across 3 diverse, community catchment areas and (2) to develop a screening questionnaire, inclusive of both symptom-based and risk factor-based questions. Our study will develop an essential screening tool that will identify which individuals have the greatest need of follow-up with structured interviews in both research and clinical settings. Our study has the potential for major contributions to the early detection and prevention of psychotic disorders.

Abstract
In community studies, both attenuated psychotic symptoms (APS) and basic symptoms (BS) were more frequent but less clinically relevant in children and adolescents compared to adults. In doing so, they displayed differential age thresholds that were around age 16 for APS, around age 18 for perceptive BS, and within the early twenties for cognitive BS. Only the age effect has previously been studied and replicated in clinical samples for APS. Thus, we examined the reported age effect on and age thresholds of 14 criteria-relevant BS in a patient sample at clinical-high risk of psychosis (N = 261, age 15-40 yrs.), recruited within the European multicenter PRONIA-study. BS and the BS criteria, "Cognitive Disturbances" (COGDIS) and "Cognitive-perceptive BS" (COPER), were assessed with the "Schizophrenia Proneness Instrument, Adult version" (SPI-A). Using logistic regressions, prevalence rates of perceptive and cognitive BS, and of COGDIS and COPER, as well as the impact of social and role functioning on the association between age and BS were studied in three age groups (15-18 years, 19-23 years, 24-40 years). Most patients (91.2%) reported any BS, 55.9% any perceptive and 87.4% any cognitive BS. Furthermore, 56.3% met COGDIS and 80.5% COPER. Not exhibiting the reported differential age thresholds, both perceptive and cognitive BS, and, at trend level only, COPER were less prevalent in the oldest age group (24-40 years); COGDIS was most frequent in the youngest group (15-18 years). Functional deficits did not better explain the association with age, particularly in perceptive BS and cognitive BS meeting the frequency requirement of BS criteria. Our findings broadly confirmed an age threshold in BS and, thus, the earlier assumed link between presence of BS and brain maturation processes. Yet, age thresholds of perceptive and cognitive BS did not differ. This lack of differential age thresholds might be due to more pronounced the brain abnormalities in this clinical sample compared to earlier community samples. These might have also shown in more frequently occurring and persistent BS that, however, also resulted from a sampling toward these, i.e., toward COGDIS. Future studies should address the neurobiological basis of CHR criteria in relation to age.
