Review of factors resulting in systemic biases in the screening, assessment, and treatment of individuals at clinical high-risk for psychosis in the United States

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. 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. CONCLUSIONS: Collectively, 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\u27s 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

Diagnostic Testing of Pediatric Fevers: Meta-Analysis of 13 National Surveys Assessing Influences of Malaria Endemicity and Source of Care on Test Uptake for Febrile Children under Five Years.

In 2010, the World Health Organization revised guidelines to recommend diagnosis of all suspected malaria cases prior to treatment. There has been no systematic assessment of malaria test uptake for pediatric fevers at the population level as countries start implementing guidelines. We examined test use for pediatric fevers in relation to malaria endemicity and treatment-seeking behavior in multiple sub-Saharan African countries in initial years of implementation. We compiled data from national population-based surveys reporting fever prevalence, care-seeking and diagnostic use for children under five years in 13 sub-Saharan African countries in 2009-2011/12 (n = 105,791). Mixed-effects logistic regression models quantified the influence of source of care and malaria endemicity on test use after adjusting for socioeconomic covariates. Results were stratified by malaria endemicity categories: low (PfPR2-10<5%), moderate (PfPR2-10 5-40%), high (PfPR2-10>40%). Among febrile under-fives surveyed, 16.9% (95% CI: 11.8%-21.9%) were tested. Compared to hospitals, febrile children attending non-hospital sources (OR: 0.62, 95% CI: 0.56-0.69) and community health workers (OR: 0.31, 95% CI: 0.23-0.43) were less often tested. Febrile children in high-risk areas had reduced odds of testing compared to low-risk settings (OR: 0.51, 95% CI: 0.42-0.62). Febrile children in least poor households were more often tested than in poorest (OR: 1.63, 95% CI: 1.39-1.91), as were children with better-educated mothers compared to least educated (OR: 1.33, 95% CI: 1.16-1.54). Diagnostic testing of pediatric fevers was low and inequitable at the outset of new guidelines. Greater testing is needed at lower or less formal sources where pediatric fevers are commonly managed, particularly to reach the poorest. Lower test uptake in high-risk settings merits further investigation given potential implications for diagnostic scale-up in these areas. Findings could inform continued implementation of new guidelines to improve access to and equity in point-of-care diagnostics use for pediatric fevers

Contextual Correlates of Mental Health Care Utilization in Youth and Young Adults at Clinical High Risk for Psychosis

Clinical high-risk (CHR) for psychosis is associated with distress, impairment, and elevated risk for developing full threshold psychosis. Though early intervention can improve prognostic outcomes in early psychosis, research on factors related to utilization of mental health services among individuals at CHR is limited. Given racial inequities in mental health care and links between CHR and sociocultural/contextual factors, an exploration of contextual correlates of mental health care utilization is needed. We conducted a secondary data analysis of an ongoing community psychosis-risk study to examine whether racialized identity, social support, racial discrimination, immigration status, and symptom severity are related to mental health care utilization among youth and young adults at CHR. Participants in the study are 16-30 year-olds who meet interview-based criteria for a psychosis-risk syndrome (n=180). Participants self-reported social support, experiences of discrimination, immigration status, and lifetime mental health care use. In regression analyses, Asian/Asian American participants were significantly less likely than White/European American participants to report receiving past mental health care, as were immigrants compared to those born in the United States. Black/African American participants were significantly less likely to report using services currently compared to White/European American participants, and distressing positive symptoms also significantly predicted receiving current services in the full sample. Overall, recent positive symptoms may be more closely associated with current service use, while sociocultural factors such as immigration status and racial identity may impact initial entry into or use of the mental health care system. As CHR research and practice increasingly focus on early intervention, findings underscore the importance of better understanding factors associated with mental health service use among youth at CHR

Race Moderates the Relation between Internalized Stigma and Suicidal Thoughts and Behaviors in Youth with Psychosis-Risk Syndromes and Early Psychosis.

Suicide is a leading cause of death among youth on the psychosis spectrum. Internalized mental health stigma is one risk factor for suicide that may be particularly salient for youth with psychosis-risk syndromes and early psychosis. Among this population, Black youth may face exposure to racism-related stressors that may exacerbate the negative effects of internalized stigma. This study examined whether internalized stigma and race interact to predict suicidal thoughts and behaviors (STB) in a help-seeking sample of Black and White adolescents with psychosis-risk syndromes and early psychosis. Findings suggest that Black youth with early psychosis spectrum disorders may be particularly vulnerable to the negative effects of internalized stigma as they pertain to STB. Internalized stigma may therefore represent an important treatment target in suicide prevention efforts among this population

Social work training to reduce duration of untreated psychosis: Methodology and considerations of a web-based training for community providers.

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. RESULTS: The web-based study enrolled 1384 individuals. More than half of study participants enrolled within the first 3 months of the 14-month recruitment period. Completion of all study components was achieved by 959 individuals (69% of total enrolled), and completion status did not vary significantly by gender, ethnicity, or facility at which the individual was employed. Completion rates varied by race, such that participants identifying as White were more likely to complete the study, while those identifying as Black were less likely. DISCUSSION: The results suggest the feasibility of using a web-based training program to engage social workers in early psychosis identification practices. Challenges related to encouraging participants to complete the training and lessons learned during the study recruitment are discussed

The influence of psychotic-like experiences on intent to seek treatment: Findings from a multi-site community survey of mental health experiences.

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. Non-help-seeking participants ages 16-30&nbsp;years (nanalysis&nbsp;=&nbsp;2529) in a multi-site study completed online questionnaires of PLEs (PRIME with distress), depression (CESD), anxiety (STAI), and intention to seek mental health treatment. Associations between PLEs and intent to seek treatment were analyzed through multiple linear regressions. PRIME scores predicted intent to seek treatment, and item-level analyses suggested that this association was driven by items 12 (going crazy), 7 (wondering if people may hurt me), 5 (confused if things are real or imagination/dreams), and 1 (odd/unusual things going on). When accounting for the effects of anxiety and depression, PLE sum scores as well as individual experiences remained statistically significant, although effect sizes were negligible. Findings suggest that PLEs can play a role in identifying individuals who intend to seek mental health services and warrant further research in independent samples

Telepsychotherapy with Youth at Clinical High Risk for Psychosis: Clinical Issues and Best Practices during the COVID-19 Pandemic.

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. Telepsychotherapy holds promise for reaching this population, especially during the current COVID-19 outbreak. However, there are limited evidence-based guidelines or interventions for use of telepsychotherapy with this population. In this paper, we review common clinical issues for individuals at CHR and how they might be exacerbated by the COVID-19 pandemic; best practices for treatment and adaptations for telepsychotherapy for individuals at CHR; and highlight real clinical issues that we are currently experiencing in a United States-based specialized CHR clinic as we conduct telepsychotherapy via videoconferencing. We conclude with questions for those in the field to contemplate, as well as potential challenges and benefits in using telepsychotherapy with individuals at CHR and their families

A microfluidic chip integrating DNA extraction and real-time PCR for the detection of bacteria in saliva

A microfluidic chip integrating DNA extraction, amplification, and detection for the identification of bacteria in saliva is described. The chip design integrated a monolithic aluminum oxide membrane (AOM) for DNA extraction with seven parallel reaction wells for real-time polymerase chain reaction (rtPCR) amplification of the extracted DNA. Samples were first heated to lyse target organisms and then added to the chip and filtered through the nanoporous AOM to extract the DNA. PCR reagents were added to each of the wells and the chip was thermocycled. Identification of Streptococcus mutans in a saliva sample is demonstrated along with the detection of 300 fg (100–125 copies) of both methicillin-susceptible Staphylococcus aureus (MSSA) and methicillin-resistant S. aureus (MRSA) genomic DNA (gDNA) spiked into a saliva sample. Multiple target species and strains of bacteria can be simultaneously identified in the same sample by varying the primers and probes used in each of the seven reaction wells. In initial tests, as little as 30 fg (8–12 copies) of MSSA gDNA in buffer has been successfully amplified and detected with this device
