RESUMEN

BACKGROUND: Perinatal depression (PND) is a debilitating condition affecting maternal well-being and child development. Allopregnanolone (ALLO) is important to perinatal neuroplasticity, however its relationship with depression severity and postpartum structural brain volume is unknown. METHOD: We examined perinatal temporal dynamics and bidirectional associations between ALLO and depression severity and the association between these variables and postpartum gray matter volume, using a random intercept cross-lagged panel model. RESULTS: We identified a unidirectional predictive relationship between PND severity and ALLO concentration, suggesting greater depression severity early in the perinatal period may contribute to subsequent changes in ALLO concentration (ß = 0.26, p = 0.009), while variations in ALLO levels during the perinatal period influences the development and severity of depressive symptoms later in the postpartum period (ß = 0.38, p = 0.007). Antepartum depression severity (Visit 2, ß = 0.35, p = 0.004), ALLO concentration (Visit 2, ß = 0.37, p = 0.001), and postpartum depression severity (Visit 3, ß = 0.39, p = 0.031), each predicted the right anterior cingulate volume. Antepartum ALLO concentration (Visit 2, ß = 0.29, p = 0.001) predicted left suborbital sulcus volume. Antepartum depression severity (Visit 1, ß = 0.39, p = 0.006 and Visit 2, ß = 0.48, p < 0.001) predicted the right straight gyrus volume. Postpartum depression severity (Visit 3, ß = 0.36, p = 0.001) predicted left middle-posterior cingulate volume. CONCLUSION: These results provide the first evidence of bidirectional associations between perinatal ALLO and depression severity with postpartum gray matter volume.

RESUMEN

While many studies have identified risk and protective factors of substance use (SU), few have assessed the reciprocal associations of child conduct problems (CP) and parenting practices and behaviors in the prediction of SU across development. A greater understanding of how these factors relate over time is needed to improve the timing of targeted prevention efforts. This study examined how child CP, parenting behaviors, and parents' own antisocial behavior relate from preschool to adolescence and eventuate in SU. Participants included 706 youth (70.6% male; 89.7% white) enrolled in the Michigan Longitudinal Study. Data from waves 1 (ages 3-5), 2 (ages 6-8), 3 (ages 9-11), 4 (ages 12-14), and 5 (ages 15-17) were included. A random intercept cross-lagged panel model (RI-CLPM) examined reciprocal associations between parenting practices, parents' antisocial behavior, and child CP over time (waves 1-4) and how these factors contribute to adolescent alcohol, cigarette, and marijuana use (wave 5). At the within-person level, negative parenting and parents' own antisocial behavior had a strong influence in late childhood/early adolescence. Only child CP emerged as a significant predictor of SU. Results highlight the importance of early intervention and the potential influence of parenting and child factors throughout development in the prevention of SU.

RESUMEN

The interdisciplinary field of developmental psychopathology has made great strides by including context into theoretical and empirical approaches to studying risk and resilience. Perhaps no context is more important to the developing child than their relationships with their caregivers (typically a child's parents), as caregivers are a key source of stimulation and nurturance to young children. Coupled with the high degree of brain plasticity in the earliest years of life, these caregiving relationships have an immense influence on shaping behavioral outcomes relevant to developmental psychopathology. In this article, we discuss three areas within caregiving relationships: (1) caregiver-child interactions in everyday, naturalistic settings; (2) caregivers' social cognitions about their child; and (3) caregivers' broader social and cultural context. For each area, we provide an overview of its significance to the field, identify existing knowledge gaps, and offer potential approaches for bridging these gaps to foster growth in the field. Lastly, given that one value of a scientific discipline is its ability to produce research useful in guiding real-world decisions related to policy and practice, we encourage developmental psychopathology to consider that a focus on caregiving, a modifiable target, supports this mission.

RESUMEN

Prior work emphasizes involving caregivers in youth mental health services. To support youth with emotion dysregulation, dialectical behavior therapy for adolescents (DBT-A) includes a multi-family skills group, wherein adolescents and caregivers learn skills together. However, limited work has examined the impact of caregiver involvement within DBT-A. The current study examines outcomes of two caregiver-only DBT-A skills groups adapted for abbreviated telehealth delivery. We report on caregivers' (N = 11, 100% mothers, 55% Hispanic) service user outcomes (e.g. self-efficacy at skill usage, group cohesion, therapeutic alliance) and clinical outcomes (i.e. their own emotion functioning, criticism, responses to their adolescent's negative emotions). Results indicate caregiver-only groups were feasible and acceptable, and suggest preliminary efficacy, including improvements in caregiver emotion functioning, distress during interactions with their adolescents, and adolescent-reported criticism. Caregivers also reported reductions in unsupportive responses with their adolescents. Overall, while we caution interpretation due to a small sample size, findings support the preliminary feasibility and efficacy of modifying caregiver participation in DBT-A to be less time-consuming and administered via telehealth.

RESUMEN

Despite the significant increase in adolescent mental health challenges in recent years, structural barriers continue to limit access to and engagement in mental health services. As such, opportunities to learn directly from adolescents and their families on how to best structure and deliver services are paramount. The current study assumes a multi-informant approach and reports on adolescents' and caregivers' (N = 33) experiences in an adapted telehealth/hybrid Dialectical Behavior Therapy for Adolescents (DBT-A) program. Focus groups were conducted across two cohorts of families who participated in DBT-A skills groups, to collect family-centered data on the acceptability of program modifications, engagement in the adapted telehealth/hybrid DBT-A, and recommendations for improvement. Participants were predominately Latine White and were from a broad range of socioeconomic backgrounds. Additionally, 45.5% of the adolescents identified as LGBTQ + . Focus group findings emphasized how the telehealth platform was both convenient and disengaging, and how in-person sessions offered improved group connection and content engagement. Participants underscored the importance of balancing multi-family group sessions with adolescent- and caregiver-only group sessions in the program, and adolescents emphasized a need for the DBT-A program to better center adolescents' unique experiences and voices throughout sessions. Both adolescents and caregivers suggested modifications to synthesize the content and improve generalizability of the DBT-A skills to their real lives. Overall, these findings add to a new and evolving branch of DBT-A qualitative inquiry, as well as the growing body of work that recommends incorporating the voices of people with lived experiences into the development and modification of psychological services.

RESUMEN

BACKGROUND: Screen media activity (SMA) can negatively affect youth behavioral health. Sleep may mediate this association but has not been previously explored. We examined whether sleep mediated the association between SMA and youth behavioral health among a community sample. METHOD: Parents completed questions about their child (N = 564) ages 3-17 at Wave 1, Wave 2 (4-8 months later), and Wave 3 (12 months later). Path analyses were conducted to examine links between Wave 1 SMA and Wave 3 behavioral health problems (i.e., internalizing, externalizing, attention, peer problems) through Wave 2 sleep disturbance and duration. RESULTS: SMA was significantly associated with greater sleep disturbance, ß = .11, 95% CI [.01, .21] and shorter sleep duration, ß = -.16 [-.25, -.06], and greater sleep disturbance was associated with worse youth behavioral health across internalizing, ß = .14 [.04, .24], externalizing, B = .23 [.12, .33], attention, ß = .24 [.15, .34], and peer problems, ß = .25 [.15, .35]. Longer sleep duration was associated with more externalizing, ß = .13 [.04, .21], and attention problems, ß = .12 [.02, .22], and fewer peer problems, ß = -.09 [-.17, -.01], but not with internalizing problems. Lastly, there was a direct effect of SMA on peer problems, ß = -.15 [-.23, -.06] such that higher SMA that does not impact sleep may have a positive impact on reducing peer problems. CONCLUSIONS: Sleep (i.e., disturbances and shorter duration) may partially account for the small associations observed between SMA and worse behavioral health in youth. To continue expanding our understanding, future research should utilize more diverse representative samples, use objective measures of SMA and sleep, and examine other relevant aspects of SMA, including content, device type, and timing of use.

RESUMEN

BACKGROUND: Early-onset (3-8 years old) disruptive behavior disorders (DBDs) have been linked to a range of psychosocial sequelae in adolescence and beyond, including delinquency, depression, and substance use. Given that low-income families are overrepresented in statistics on early-onset DBDs, prevention and early-intervention targeting this population is a public health imperative. The efficacy of Behavioral Parent Training (BPT) programs such as Helping the Noncompliant Child (HNC) has been called robust; however, given the additional societal and structural barriers faced by low-income families, family engagement and retention barriers can cause effects to wane with time. This study extends preliminary work by examining the potential for a Technology-Enhanced HNC (TE-HNC) program to improve and sustain parent skill proficiency and child outcomes among low-income families. METHODS: A randomized controlled trial with two parallel arms was the design for this study. A total of 101 children (3-8-years-old) with clinically significant problem behaviors from low-income households were randomized to HNC (n = 54) or TE-HNC (n = 47). Participants were assessed at pre-treatment, post-treatment, 3-month, and 6-month follow-ups. Primary outcomes were parent-reported and observed child behavior problems. Secondary outcomes included observed parenting skills use (ClinicalTrials.gov Identifier: NCT02191956). RESULTS: Primary analyses used latent curve modeling to examine treatment differences in the trajectory of change during treatment, maintenance of treatment gains, and levels of outcomes at the 6-month follow-up. Both programs yielded improvements in parenting skills and child problems at post-treatment. However, TE-HNC families evidenced greater maintenance of parent-reported and observed child behavior and observed positive parenting skills at the 6-month follow-up. CONCLUSIONS: Our findings contribute to an ongoing line of work suggesting that technology-enhanced treatment models hold promise for increasing markers of engagement in BPT and sustaining long-term outcomes among low-income families.

RESUMEN

Adverse childhood experiences (ACEs) put millions of children at risk for later health problems. As childhood represents a critical developmental period, it is important to understand how ACEs impact brain development in young children. In addition, children with attention-deficit/hyperactivity disorder (ADHD) are more likely than typically developing (TD) peers to experience ACEs. Therefore, the current study examined the impact of ACEs on early brain development, using a cumulative risk approach, in a large sample of children with and without ADHD. We examined 198 young children (Mage  = 5.45, 82.3% Hispanic/Latino; 52.5% ADHD) across measures of brain volume, cortical thickness, neurite density index (NDI), and orientation dispersion index (ODI). For the NDI measure, there was a significant interaction between group and cumulative risk (ß = .18, p = .048), such that for children with ADHD, but not TD children, greater cumulate risk was associated with increased NDI in corpus callosum. No other interactions were detected. Additionally, when examining across groups, greater cumulative risk was associated with reduced ODI and volume in the cerebellum, although these findings did not survive a correction for multiple comparisons. Our results highlight the role early cumulative ACEs play in brain development across TD and children with ADHD.

RESUMEN

The current study utilized mediation analyses to examine how parental symptoms of depression and anxiety impact child emotion regulation (ER) and emotion stability (ES) through parent emotion functioning, parenting, and the coparent relationship. 564 parents of children between 3 and 17 years (Mage = 9.47; 54.4% male) were recruited via Amazon's Mechanical Turk across three time points: baseline (Wave 1), 4 months (Wave 2), 8 months (Wave 3). Mediation results demonstrated that symptoms of parent depression at Wave 1 predicted worse coparent relationships and decreases in parents' ability to identify their own emotions at Wave 2. Symptoms of parental anxiety at Wave 1 predicted decreases in positive parenting and an increased tendency to have negative secondary emotional responses, impulse-control difficulties, and difficulty accessing emotion-regulation strategies at Wave 2. Additionally, symptoms of parental anxiety at Wave 1 directly predicted lower child ER and ES at Wave 3. However, no significant indirect pathways were identified between parent symptoms and child ER and ES. Sensitivity analyses examined the effects of three youth developmental stages (i.e., early and middle childhood and adolescence), as well as parent gender (i.e., mother and father), and found no significant differences across groups. Thus, even at non-clinical levels, parental symptoms of anxiety and depression may negatively impact parenting, parent regulation, and the coparent relationship, while parental anxiety symptoms may contribute to lower child ER and ES.

RESUMEN

BACKGROUND: Peripartum depression (PND) impairs mother-infant boding and perceived social support, yet limited research has examined if women at-risk for PND (AR-PND) also experience impairment. We examined if pregnant women AR-PND, women with PND, and healthy comparison women (HCW) differed in their mother-infant bonding and social support. As PND is highly comorbid with anxiety, we also examined if peripartum anxiety impacted postpartum diagnosis of PND. METHODS: A total of 144 pregnant women AR-PND or euthymic were assessed twice antepartum and twice postpartum. We utilized regression models to examine the impact of PND risk group status and diagnostic status on mother-infant bonding and perceived social support postpartum. We conducted a sensitivity analysis using a generalized estimating equations model to determine if anxiety (Hamilton Anxiety Rating Scale, HAM-A) across all four time points was associated with the postpartum diagnosis of PND. RESULTS: Women AR-PND experienced significantly worse mother-infant bonding compared to HCW (p = .03). Women diagnosed with PND experienced significantly worse mother-infant bonding and social support compared to HCW (p = .001, p = .002, respectively) and to those who were at-risk for but did not develop PND (p = .02, p = .008, respectively). HAM-A severity at each visit was associated with PND diagnosis status, where each increase in HAM-A was associated with 15% increased odds of being diagnosed with PND postpartum. CONCLUSIONS: Both women AR-PND and those with PND experience worse mother-infant bonding. Peripartum anxiety should also be assessed as it represents a marker for later PND.

RESUMEN

Objective: This study examined associations between temperament (negative affect, effortful control, and surgency) and symptoms of attention-deficit/hyperactivity disorder (ADHD) and oppositional defiant disorder (ODD) within a diverse preschool sample. Interactions between temperament and parenting in the prediction of ADHD/ODD symptoms before and after an 8-week early intervention program (i.e., Summer Treatment Program for Pre-kindergartners; STP-PreK) were also examined.Method: The sample included 215 children (Mage = 5.0, 80.9% male, 84.7% Latinx) with a diagnosis of ADHD and/or ODD who completed the STP-PreK. Temperament was measured via parent report while ADHD/ODD symptoms were assessed via combination of parent and teacher report. Positive and negative parenting were assessed via rating scales and a standardized parent-child interaction observation.Results: Higher surgency was associated with greater symptom severity of ADHD/ODD pre- and post-treatment. Higher negative affect was associated with greater symptom severity of ODD pre- and post-treatment, while higher effortful control was only associated with lower symptom severity of inattention pre-treatment. Positive parenting predicted lower symptom severity of ADHD/ODD post-treatment. Moderation analyses indicated that the benefits of low levels of negative parenting only occurred when paired with low temperament risk for symptoms of hyperactivity and ODD. Additionally, only the combination of high surgency and high observed negative parenting resulted in greater symptom severity of ODD. Finally, decreases in inconsistent discipline predicted decreases across all symptom domains post-treatment.Conclusions: Our findings add to the temperament-based model of ADHD/ODD by highlighting temperament's unique prediction of treatment response as well as important interactions with the caregiving environment.

RESUMEN

This study examined the cost-effectiveness of standard parent-child interaction therapy (PCIT) and three adaptations: intensive-PCIT (I-PCIT), small group PCIT, and large group PCIT. This study used cost-effectiveness analyses to calculate average cost-effectiveness ratios, which represents the average cost for one family to change one standard deviation on each outcome measure: externalizing behavior problems, positive parenting skills, negative parenting skills, child compliance, and parenting stress. While it had the lowest initial set up cost, results indicated that standard PCIT was the least cost-effective option in reducing child disruptive behaviors and in increasing child compliance. Large group PCIT was the most cost-effective in increasing positive parenting skills and child compliance and in reducing negative parenting skills and parenting stress. I-PCIT was the most cost-effective in reducing child disruptive behaviors and the second most cost-effective option in increasing positive parenting skills and child compliance and in decreasing negative parenting. As large group and I-PCIT were the most cost-effective in different domains, both could be recommended to parents as treatment options. Future research should confirm our cost-effective results within community settings.

RESUMEN

Sudden unexpected death in epilepsy (SUDEP) is a leading cause of premature death in patients with epilepsy. One hypothesis proposes that sudden death is mediated by post-ictal central respiratory depression, which could relate to underlying pathology in key respiratory nuclei and/or their neuromodulators. Our aim was to investigate neuronal populations in the ventrolateral medulla (which includes the putative human pre-Bötzinger complex) and the medullary raphe. Forty brainstems were studied comprising four groups: 14 SUDEP, six epilepsy controls, seven Dravet syndrome cases and 13 non-epilepsy controls. Serial sections through the medulla (from obex 1 to 10 mm) were stained for Nissl, somatostatin, neurokinin 1 receptor (for pre-Bötzinger complex neurons) and galanin, tryptophan hydroxylase and serotonin transporter (neuromodulatory systems). Using stereology total neuronal number and densities, with respect to obex level, were measured. Whole slide scanning image analysis was used to quantify immunolabelling indices as well as co-localization between markers. Significant findings included reduction in somatostatin neurons and neurokinin 1 receptor labelling in the ventrolateral medulla in sudden death in epilepsy compared to controls (P < 0.05). Galanin and tryptophan hydroxylase labelling was also reduced in sudden death cases and more significantly in the ventrolateral medulla region than the raphe (P < 0.005 and P < 0.05). With serotonin transporter, reduction in labelling in cases of sudden death in epilepsy was noted only in the raphe (P ≤ 0.01); however, co-localization with tryptophan hydroxylase was significantly reduced in the ventrolateral medulla. Epilepsy controls and cases with Dravet syndrome showed less significant alterations with differences from non-epilepsy controls noted only for somatostatin in the ventrolateral medulla (P < 0.05). Variations in labelling with respect to obex level were noted of potential relevance to the rostro-caudal organization of respiratory nuclear groups, including tryptophan hydroxylase, where the greatest statistical difference noted between all epilepsy cases and controls was at obex 9-10 mm (P = 0.034), the putative level of the pre-Bötzinger complex. Furthermore, there was evidence for variation with duration of epilepsy for somatostatin and neurokinin 1 receptor. Our findings suggest alteration to neuronal populations in the medulla in SUDEP with evidence for greater reduction in neuromodulatory neuropeptidergic and mono-aminergic systems, including for galanin, and serotonin. Other nuclei need to be investigated to evaluate if this is part of more widespread brainstem pathology. Our findings could be a result of previous seizures and may represent a pathological risk factor for SUDEP through impaired respiratory homeostasis during a seizure.

RESUMEN

Depression is the most common perinatal psychiatric disorder, but little is known about how it may impact offspring neurodevelopment, as well as the mechanisms by which it may confer transgenerational psychiatric risk. This review presents imaging studies conducted to evaluate the relationship between perinatal depression (PND) and infant and child neurodevelopment. Altered structural and functional connectivity is implicated in children exposed to PND and anxiety. Overall, there are changes in connectivity between amygdala and the prefrontal cortex. Studies suggest decreased hippocampal growth in the first 6 months after birth, decreased cortical thickness in children, and increased amygdala volumes, that are more pronounced in female offspring. Future research is needed to understand the impact of PND on development so that early interventions which promote mother-infant bonding and cognitive development may improve developmental outcomes in children exposed to PND, reducing later risk of psychopathology.

RESUMEN

The neuronal ceroid lipofuscinoses are a group of recessively inherited, childhood-onset neurodegenerative conditions. Several forms are caused by mutations in genes encoding putative lysosomal membrane proteins. Studies of the cell biology underpinning these disorders are hampered by the poor antigenicity of the membrane proteins, which makes visualization of the endogenous proteins difficult. We have used Drosophila to generate knock-in YFP-fusions for two of the NCL membrane proteins: CLN7 and CLN3. The YFP-fusions are expressed at endogenous levels and the proteins can be visualized live without the need for overexpression. Unexpectedly, both CLN7 and CLN3 have restricted expression in the CNS of Drosophila larva and are predominantly expressed in the glia that form the insect blood-brain-barrier. CLN7 is also expressed in neurons in the developing visual system. Analogous with murine CLN3, Drosophila CLN3 is strongly expressed in the excretory and osmoregulatory Malpighian tubules, but the knock-in also reveals unexpected localization of the protein to the apical domain adjacent to the lumen. In addition, some CLN3 protein in the tubules is localized within mitochondria. Our in vivo imaging of CLN7 and CLN3 suggests new possibilities for function and promotes new ideas about the cell biology of the NCLs.

RESUMEN

Experiencing homelessness in infancy has been linked to negative physical and mental health outcomes. Parental well-being and the parent-infant relationship can also be negatively impacted by experiencing homelessness. While numerous parent-based infant mental health programs have been identified by a recent review, the goal of this study was to further determine the extent to which these existing programs were developed and/or examined with at-risk populations such as families experiencing homelessness. Out of 60 programs identified by Hare et al., in press, only three had been implemented specifically in shelter settings with infants 0-12 months (Parent-Infant Psychotherapy, New Beginnings, and My Baby's First Teacher). Additionally, when examining programs that began in later infancy (after 12 months), only 2 programs were implemented in shelter settings (Incredible Years and Parent-Child Interaction Therapy). Implications for research, policy, and clinicians regarding implementation of evidence-based prevention/treatment programs for parents and their infants experiencing homelessness are discussed.

RESUMEN

Although many prevention and treatment programs exist for children and families, there have been no reviews specifically examining their impact on infant mental health at the program level. Therefore, the purpose of the current review was to a) systematically examine prevention and treatment programs targeting infant mental health outcomes (i.e., internalizing problems, externalizing problems, social-emotional development, trauma) or the parent-infant relationship/ attachment in children from pregnancy to 2 years; b) classify each program by level of empirical support; and c) highlight strengths and identify gaps in the existing literature to inform future mental health intervention science. From over 121,341 publications initially identified, 60 prevention and treatment programs met inclusion criteria for this review. Each program was reviewed for level of scientific evidence. Of the 60 programs reviewed, 29 (48.33%) were classified as promising, while only six (10.0%) were classified as effective. Lastly, only two programs (3.33%; Attachment and Biobehavioral Catch-Up and Video-feedback Intervention Parenting Program) were classified as evidence-based specific to infant mental health and/or parent-infant relationship/attachment outcomes. Implications related to disseminating evidence-based prevention/treatment programs are discussed.

RESUMEN

Parental factors, including negative parenting practices (e.g., family conflict, low monitoring), parental depression, and parental substance use, are associated with externalizing behaviors among youth. However, the ways in which these parental factors are associated with youth brain function and consequent externalizing behavior has been less studied. Both the dimensional and stress acceleration models provide frameworks for understanding how parental factors may be associated with frontolimbic and frontoparietal networks implicated in emotional attention and regulation processes. The current review builds upon this work by examining how deprivation- and threat-based parental factors are associated with youth neurocircuitry involved in emotional functioning and externalizing behaviors. A systematic review using PRISMA guidelines was completed and included five studies assessing parenting behaviors, six studies assessing parental depressive symptoms and/or diagnosis, and 12 studies assessing parental history of substance use. Synthesis of reviewed studies discusses support for the dimensional and stress acceleration models within the context of deprivation and threat. Further, a limited number of studies tested (i.e., six studies) and supported (i.e., three studies) youth neural structure and function as a mediator of the association between parental factors and youth externalizing behavior. Specific recommendations for future work include more deliberate planning related to sample composition, improved clarity related to parental constructs, consistency in methodology, and longitudinal study design in order to better understand associations between contextual parental influences and youth neural and behavioral functioning.

RESUMEN

The COVID-19 pandemic led many in-office therapeutic programs to pivot to virtual programming without empirical data supporting the acceptability and efficacy of the remote-delivered adaptations. These adaptations were essential for continuing care and addressing surging youth psychological problems at the time. To serve adolescents with comorbid psychiatric disorders and associated problems (e.g., emotion dysregulation), we adapted and implemented virtual and hybrid formats of a dialectical behavior therapy for adolescents (DBT-A; Rathus & Miller, 2015) program within a public university training clinic, such as separating the traditional multifamily group into adolescent-only and caregiver-only groups. Building on qualitative reports on virtual DBT-A, we explored preliminary service user and clinical outcomes of the virtual and hybrid DBT-A adolescent skills group component in a longitudinal retrospective cohort study for teenagers treated during the first 2 years of the pandemic (N = 21; 81% Hispanic/Latinx; 100% White). Aim 1 described service user outcomes (e.g., retention, group cohesion, client satisfaction) in the remote-delivered skills groups. Most youth completed treatment. Caregiver satisfaction was high, whereas adolescent satisfaction was mild. Aim 2 explored preliminary clinical outcomes of remote-delivered skills group adaptations. Overall anxiety, panic, and two emotion regulation facets (i.e., emotional awareness; goal pursuit when upset) significantly reduced across treatment. There were no significant reductions in depression. No suicide attempts or suicides occurred during the program. Further work is needed to clarify the efficacy of telehealth formats of DBT-A skills groups in larger, more racially diverse samples and to identify which adolescents are most appropriate for virtual and/or hybrid DBT-A.

RESUMEN

Demographic data from nearly 50 years of treatment research for children and adolescents with attention-deficit/hyperactivity disorder (ADHD) are synthesized. Comprehensive search identified ADHD treatment studies that were between-group designs, included a psychosocial, evidence-based treatment, and were conducted in the United States. One hundred and twenty-six studies that included 10,604 youth were examined. Reporting of demographics varied with 48% of studies (k = 61) reporting ethnicity, 73% (k = 92) reporting race, 80% (k = 101) reporting age (M age = 8.81, SD = 2.82), and 88% (k = 111) reporting gender. Most participants identified as non-Hispanic/Latine (15.99% Hispanic/Latine), White (62.54%), and boys (74.39%; 24.47% girls). Since the 1970s, zero youth in ADHD treatment studies identified as Middle Eastern/North African, 0.1% were American Indian/Alaskan Native or Native Hawaiian Pacific Islander, 1.77% were Asian, 15.10% were Black, and 3.14% were Multiracial. Based on publication year, the proportions of girls, racially minoritized youth, and Hispanic/Latine youth included in ADHD treatment research have increased over time. Girls, non-binary and non-cisgender youth, young children, adolescents, Hispanic/Latine youth, and youth from all racial groups other than White are underrepresented in ADHD treatment research. Research gaps are discussed, and recommendations for comprehensive demographic reporting in child and adolescent psychological research are provided.
