BACKGROUND:Research demonstrates the effectiveness of evidence-based psychological treatment adjunctive to pharmacotherapy for reducing mood symptoms in bipolar disorder. However, access to these treatments is limited, and innovative strategies are needed to ensure that more patients with bipolar disorder receive the gold-standard treatments that may help them achieve wellness. "Stepped care" models of psychological service delivery represent one potential solution to this problem of treatment access. Under a stepped care model, patients are assigned the minimum necessary psychological treatment for symptom improvement. This typically means that patients who are experiencing more symptoms are assigned to a treatment of greater intensity (e.g., weekly individual therapy) whereas patients who are experiencing fewer symptoms are assigned to a treatment of relatively lesser intensity (e.g., biweekly group therapy). Stepped care models are dynamic, meaning that the level of treatment can be modified depending on the patient's response. Stepped care models have been explored in other clinical populations but require further exploration in bipolar disorder. METHODS:Members of the Psychological Interventions Task Force for the International Society of Bipolar Disorders conducted a narrative review of stepped care models and their application to bipolar disorder. RESULTS:We found evidence that stepped care models are useful approaches to delivering psychosocial treatments for bipolar disorder. We discuss several contextual factors in executing stepped care models in this population (i.e., cultural and pediatric applications), as well as share an example of a stepped care model-Focused Integrated Team-based Treatment for Bipolar Disorder (FITT-BD)-that is currently being evaluated in an academic medical center. CONCLUSION/CONCLUSIONS:Further research is warranted to develop and assess robust stepped care models to determine whether they can improve access to treatment of bipolar disorder while not sacrificing outcomes.

In this Personal View, we address key questions to support evidence-based prevention and management of psychotic symptoms that might occur during ADHD pharmacotherapy. We begin by examining evidence showing a significantly increased occurrence of psychotic disorders in individuals with ADHD, independent of ADHD medications (pooled relative risk, odds ratio, or hazard ratio=4·74, 95% CI 4·11-5·46). We then examine whether ADHD medications play a causal role, noting that current evidence does not support such a causal link, at least for methylphenidate. We explore how vulnerability to psychosis varies across individuals with ADHD. Regarding the different steps involved in prescribing ADHD medications, we discuss the importance of balancing potential risks-such as emergence of psychotic symptoms-against the demonstrated benefits of pharmacological treatment for ADHD. Next, we present strategies for screening individuals for vulnerability to psychosis before initiating ADHD medication. We then offer guidance on the clinical management of psychotic symptoms that might arise during ADHD pharmacotherapy, including considerations of dosage and medication type. Finally, we identify key research priorities in this area. Overall, this paper provides an empirical framework, grounded in evidence and clinical practice, to guide the next steps in the field.

Autism spectrum disorder (ASD) is a neurodevelopmental condition, with ex vivo studies suggesting its neurobiological origin as early as the first and second trimester of pregnancy. Functional MRI studies using graph-theoretical approaches have isolated features in the global connectome architecture that distinguish toddlers with ASD from their typically developing peers. Additionally, functional connectivity patterns in the infant brain have shown to be predictive of later ASD diagnosis. An important yet unexplored question in the literature is whether graph-theoretical differences are evident prior to infancy, in the brain of fetuses who will later exhibit ASD traits in early childhood. In this study, we address this question using a sample of 88 children with both quality-assured fetal brain resting-state functional MRI data and standardized parent assessment of ASD traits including social-emotional and social communication skills and repetitive and restricted behaviors at age 3. Multiple regression analyses revealed no significant associations between fetal global graph features (e.g., network segregation, integration, and small-world architecture) and ASD traits at age 3 (p's > 0.1). Therefore, our findings do not provide support for prenatal emergence of global topographical differences of brain functional organization in fetuses who later develop ASD traits. However, this does not rule out the possibility of other neural signatures in the fetal functional connectome that may predict autistic traits and future ASD diagnosis.

OBJECTIVE:Pediatric primary care (PPC) offers an ideal platform for integrating evidence-based programs (EBPs) to enhance early relational health (ERH). However, implementing such integration faces several challenges. This study uses quantitative and qualitative data to identify the barriers, facilitators, and strategies for implementing ERH-focused EBPs in PPC. METHODS:Using the Consolidated Framework for Implementation Research framework, we conducted a survey and focus groups with PPC personnel recruited through nationwide networks. The survey measured clinic readiness (i.e., challenges, resources, and needs) for integration and examined its associations with personnel roles and clinic characteristics using nested ANOVAs and multilevel regressions. Focus groups further probed potential strategies and were coded using thematic analysis. RESULTS:126 PPC personnel from 44 clinics completed the survey, and 18 participated in five focus groups. Clinics had strong leadership support for integrated services and high utilization of program resources and implementation practices, yet notable challenges in structural and human resources existed. Clinic staff perceived higher readiness for integration than other personnel roles. Lower-percent Medicaid eligible patients and urbanicity were associated with higher readiness, while academic affiliation showed both positive and negative associations. Promoting culturally responsive care, fostering team cohesion, utilizing standardized implementation processes, adopting flexible delivery and collaborative models, and partnering with local communities were key strategies for integrating EBPs. CONCLUSIONS:The findings can help PPC clinics more effectively integrate one or multiple EBPs into routine care and can inform ways to sustain such integrated services to optimize population-level reach and positive impacts on child and family well-being.

Insurance type is a key indicator of structural vulnerability in pediatric mental health care and may be associated with differences in psychiatric presentation, treatment course, and diagnosis among hospitalized youth, particularly Black and Hispanic/Latino children insured by Medicaid. Despite these inequities, their impact remains understudied among psychiatrically hospitalized pediatric populations. This retrospective study analyzed 1,101 child and adolescent psychiatric patients admitted to an urban psychiatric hospital between June 2018 and November 2021. Clinical presentation, psychiatric history, treatment course, and discharge diagnoses were compared between patients' insurance by Medicaid (72%) and those with commercial insurance (28%). Compared with commercially insured patients, children and adolescents with Medicaid were more likely to be Black or Hispanic/Latino and had higher rates of trauma exposure, prior psychiatric emergency visits, and higher rates of attention-deficit/hyperactivity disorder (ADHD), impulsive/behavioral disorders, and developmental/intellectual disorders. They were more frequently admitted for aggression-related crises, more likely to receive emergency injectable medications for agitation, and had longer hospital stays. Commercially insured patients had higher rates of anxiety disorders and suicide attempt related admissions. These findings suggest children and adolescents with Medicaid who required psychiatric hospitalization had greater severity of psychosocial histories and higher-acuity inpatient courses, highlighting how structural inequities reflected by insurance type, may shape differing psychiatric treatment pathways, underscoring the need for equity-oriented interventions, particularly during periods of healthcare system strains.

Although temperamental negative affectivity has been identified as a developmental mechanism mediating the link between perinatal risk and internalizing problems in early childhood, its role in predicting broader behavioral and emotional problems across childhood remains understudied. We examined the longitudinal relations among perinatal complications (i.e., prenatal maternal depression and cardiometabolic complications, preterm birth, and low birth weight), children's negative affectivity (M

Sleep disturbances are prominent across neurodevelopmental disorders (NDDs) and may reflect specific abnormalities in brain development and function. Overnight polysomnography (PSG) allows for detailed investigation of sleep architecture, offering a unique window into neurocircuit function. Analysis of existing pediatric PSGs from clinical studies could enhance the availability of sleep studies in pediatric patients with NDDs towards a better understanding of mechanisms underlying abnormal development in NDDs. Here, we introduce and characterize a retrospective collection of 1527 clinical pediatric overnight PSGs across five different sites. We first developed an automated stager trained on independent pediatric sleep data, which yielded better performance compared to a generic stager trained primarily on adults. Using consistent staging across cohorts, we derived a panel of EEG micro-architectural features. This unbiased approach replicated broad trajectories previously described in typically developing sleep architecture. Further, we found sleep architecture disruptions in children with Down's Syndrome (DS) that were consistent across independent cohorts. Finally, we built and evaluated a model to predict age from sleep EEG metrics, which recapitulated our previous findings of younger predicted brain age in children with DS. Altogether, by creating a resource pooled from existing clinical data we expanded the available datasets and computational resources to study sleep in pediatric populations, specifically towards a better understanding of sleep in NDDs. This Retrospective Analysis of Sleep in Pediatric (RASP) cohorts dataset, including staging annotation derived from our automated stager, is deposited at https://sleepdata.org/datasets/rasp.

Active avoidance responses (ARs) are instrumental behaviors that prevent harm. Adaptive ARs may contribute to active coping, whereas maladaptive avoidance habits are implicated in anxiety and obsessive-compulsive disorders. The AR learning mechanism has remained elusive, as successful avoidance trials produce no obvious reinforcer. We used a novel outcome-devaluation procedure in rats to show that ARs are positively reinforced by response-produced feedback cues that develop into safety signals during training. Males were sensitive to feedback devaluation after moderate training, but not overtraining, consistent with a transition from goal-directed to habitual avoidance. Using chemogenetics and feedback devaluation, we also show that goal-directed vs. habitual ARs depend on dorsomedial vs. dorsolateral striatum, suggesting a significant overlap between the mechanisms of avoidance and rewarded instrumental behavior. Females were insensitive to feedbackdevaluation due to a remarkable context-dependence of counterconditioning. However, degrading the contingency between avoidance and feedback suggests that both sexes rely on safety signals to perform goal-directed ARs.

Socioeconomic disadvantage has been established as a key risk factor for adverse child behavioral outcomes. Understanding how individual components of socioeconomic status (SES) interact with each other can elucidate protective factors and inform interventions and policies to promote positive developmental outcomes. This study examined the interactive effects of prenatal household income and neighborhood deprivation on child externalizing and internalizing problems (N = 793; M
