An update on the assessment of culture and environment in the ABCD Study®: Emerging literature and protocol updates over three measurement waves

The relationship between parenting behavior, suicidal ideation, and suicide attempt across two population-based samples of adolescents

We examined the relationship between parenting, suicidal ideation (SI), and the transition from SI to suicide attempt (SA), and whether parenting behaviors moderate the associations of genetic liability for SA and/or painful and provocative events (PPEs) with SA risk. Participants included 6153 adolescents (48.3 % female, Mage at baseline = 9.47 years, followed over 3 years) from the Adolescent Brain Cognitive Development Study (ABCD) and 5942 adolescents (52.1 % female, Mage at baseline = 15.55 years, followed over 1 year) from the National Longitudinal Study of Adolescent to Adult Health (Add Health). We used logistic regression to test associations between parenting and SI/SA. Genetic liability and PPEs were included as potential predictors of SA. In ABCD, higher parental acceptance and monitoring were associated with lower risk for SI (odds ratios [ORs] = 0.7-0.9, ps < .01) but not SA (ORs = 0.9, ps > .05). Non-suicidal self-injury and parental knowledge of child SI were associated with elevated risk for SA (ORs = 2.6-2.8, ps < .01), but their interaction was non-significant (OR = 0.9, p = .85). In Add Health, maternal support was related to reduced SI risk (OR = 0.8, p < .01), but paternal support, and both parents' involvement and presence at home, were not (ORs = 0.9-1.0, ps > .05). Several PPEs were associated with higher SA risk (ORs = 1.3-2.0, ps < .05). These findings suggest that the parent-adolescent relationship may be more relevant to SI, rather than the transition from SI to SA.

Timing matters: A multi-contextual, within-individual approach to understanding age-related changes in psychopathology in the ABCD Study

Psychopathology is associated with features of the family, neighborhood, and school environments. During adolescence, increased autonomy and novel social relationships may influence the strength of these associations over time. Characterizing these processes is key to understanding how and when different factors may contribute to psychopathology. Participants in the Adolescent Brain Cognitive Development (ABCD) Study (n = 11,823) were 9-10 years old at baseline and 12-13 years old at the three-year follow-up. At each time point, internalizing symptoms (INT) and externalizing symptoms (EXT), family features (e.g., conflict, parental monitoring, acceptance, and financial hardship), neighborhood safety, and school supportiveness were assessed. Fixed effect regression models were estimated separately for male and female youth to examine the age-varying, within-individual associations between symptoms and family, neighborhood, and school factors. INT and EXT significantly decreased among male adolescents over time, while female adolescents exhibited increases in INT and decreases in EXT. Family conflict, financial hardship, neighborhood safety, and school support predicted INT and EXT, with some variation by sex (e.g., neighborhood safety only predicted INT and EXT for male adolescents). Many of these associations were consistent over time. However, for male adolescents, the association between financial hardship and EXT weakened over time, while the family conflict and EXT association strengthened. Understanding how timing and specific environmental factors interact to shape adolescent mental health is critical to identifying periods of heightened sensitivity to risk or protective influences.

The Impact of Adversity and Family Conflict on Risk for Future Substance Use Among Young Adolescents in the Adolescent Brain Cognitive Development Study (ABCD Study): A Cohort Analysis

PROBLEM

Early initiation of substance use (≤ $\le $  14 years old) constitutes a key target for intervention strategies. This study investigated associations between exposure to adverse childhood experiences (ACEs) and risk for future substance use among young adolescents in the United States (US); the moderating effect of family conflict was also explored.

METHODS

Mixed-effects modeling was used to analyze self-report data collected from adolescents and parents at baseline and 3-year follow-up (Y3) in the Adolescent Brain Cognitive Development Study (ABCD Study) (Data Release 5.1, 2016-2022, US).

FINDINGS

After adjusting for socio-demographic covariates, significant positive associations were found between adolescent ACEs score at baseline (ages 9-10) and risk for future alcohol (b = 0.03, p < 0.001), cigarette/e-cigarette (b = 0.04, p < 0.001), and marijuana use (b = 0.06, p < 0.001) at Y3 (ages 12-13) (n = 10,213 dyads). Family conflict reported at baseline was not found to moderate these associations.

CONCLUSIONS

Cumulative ACEs exposure was associated with increased risk for future alcohol, cigarette/e-cigarette, and marijuana use among a national sample of young adolescents. Findings highlight the potential for trauma-informed, developmentally appropriate preventative interventions to mitigate risk for future substance use among adversity-impacted adolescents.

The protective role of community cohesion across rural and urban contexts: implications for youth mental health

BACKGROUND

Exposure to adversity (e.g., negative life events) and socioeconomic disadvantage can increase the risk for internalizing and externalizing symptoms, but many youth demonstrate resilience. Risk and protective factors may vary depending on geographic contexts (i.e., urban vs. rural areas). We hypothesized that community cohesion would mitigate the effects of adversity and disadvantage on youth mental health symptoms, especially among rural communities.

METHOD

Data were drawn from the Adolescent Brain Cognitive Development (ABCD) Study (n = 10,812), a longitudinal study in the United States. At baseline (9-10 years old), neighborhood socioeconomic disadvantage was measured with the Area Deprivation Index, and youth reported on the total number of negative life events they had experienced. At the 2-year follow-up, caregivers reported on cohesion within their community, and at the 3-year follow-up, they reported on their child's internalizing and externalizing symptomatology. A multiple-group path model was used to compare effects for youth living in urban versus rural areas.

RESULTS

In the urban subsample, results indicated a significant interaction between neighborhood disadvantage and community cohesion (β = -.03, p = .004), such that higher disadvantage was associated with higher externalizing (but not internalizing) symptomatology at low and medium, but not high, levels of cohesion. We identified similar patterns of results in the rural subsample, and the interaction neared conventional significance thresholds (β = -.09, p = .052). There was no significant interaction with adversity.

CONCLUSIONS

Community cohesion may serve as a protective factor for youth experiencing neighborhood disadvantage by mitigating effects on externalizing symptoms.

Whole-brain white matter variation across childhood environments

White matter develops over the course of childhood in an experience-dependent manner. However, its role in the relationship between the early environment and later cognition is unclear, in part due to focus on changes in specific gray matter regions. This study examines white matter differences across adolescents from diverse environments, evaluating both their extent throughout the brain and their contribution to cognitive outcomes. Using data from the Adolescent Brain Cognitive Development (ABCD) study (N = 9,082, female = 4,327), we found extensive cross-sectional associations with lower white matter fractional anisotropy (FA) and streamline count in the brains of 9- and 10-y-old children exposed to a range of experiences, including prenatal risk factors, interpersonal adversity, household economic deprivation, and neighborhood adversity. Lower values of FA were associated with later difficulties with mental arithmetic and receptive language. Furthermore, white matter FA partially mediated the detrimental relationship between adversity and cognition later in adolescence. These findings advance a white matter-based account of the neural and cognitive effects of adversity, which supports leading developmental theories that place interregional connectivity prior to gray matter maturation.

Longitudinal analysis of the ABCD® study

The Adolescent Brain Cognitive Development® (ABCD) Study provides a unique opportunity to investigate developmental processes in a large, diverse cohort of youths, aged approximately 9-10 at baseline and assessed annually for 10 years. Given the size and complexity of the ABCD Study, researchers analyzing its data will encounter a myriad of methodological and analytical considerations. This review provides an examination of key concepts and techniques related to longitudinal analyses of the ABCD Study data, including: (1) characterization of the factors associated with variation in developmental trajectories; (2) assessment of how level and timing of exposures may impact subsequent development; (3) quantification of how variation in developmental domains may be associated with outcomes, including mediation models and reciprocal relationships. We emphasize the importance of selecting appropriate statistical models to address these research questions. By presenting the advantages and potential challenges of longitudinal analyses in the ABCD Study, this review seeks to equip researchers with foundational knowledge and tools to make informed decisions as they navigate and effectively analyze and interpret the multi-dimensional longitudinal data currently available.

Interplay between polygenic risk and family processes in predicting trajectories of adolescent externalizing behaviors

Introduction

There is limited understanding on how polygenic scores derived from genome-wide association studies of adult and child psychopathology may uniquely predict childhood traits. The current study took a developmental approach to examine the interplay between adult-based and child-based polygenic scores with family processes in predicting trajectories of externalizing behaviors from late childhood to early adolescence among racially-ethnically diverse youth.

Method

Data were drawn from the non-Hispanic White (N = 5,907), non-Hispanic Black (N = 1,694), and Hispanic youth (N = 2,117) from the adolescent brain cognitive development (ABCD) study. Parents reported on youth externalizing behaviors at baseline (T1, age 9/10), 1-year (T2, age 10/11), 2-year (T3, age 11/12), and 3-year (T4, age 12/13) follow-up assessments. Youth reported on parenting and family environment at T1 and provided saliva or blood samples for genotyping.

Results

Both polygenic scores for adult externalizing and childhood aggression predicted greater likelihood of following trajectories with higher externalizing behaviors. Among non-Hispanic White youth, polygenic scores also predicted greater family conflict, which in turn predicted higher externalizing behavior trajectories.

Discussion

Our findings indicated that both adult-based and child-based polygenic scores for externalizing behaviors are useful in predicting trajectories of externalizing behaviors, highlighting developmental continuity in genetic influences. Family processes, especially family conflict, play an important role in adolescent externalizing behaviors across racial-ethnic groups, suggesting the need to target family conflict in intervention efforts. Findings also highlight the importance of conducting research in diverse populations, including improving diversity in genetically informed studies.

Parental warmth buffers the negative impact of weaker fronto-striatal connectivity on early adolescents' academic achievement

In past decades, the positive role of self-control in students' academic success has attracted plenty of scholarly attention. However, fewer studies have examined the link between adolescents' neural development of the inhibitory control system and their academic achievement, especially using a longitudinal approach. Moreover, less is known about the role of parents in this link. Using large-scale longitudinal data from the Adolescent Brain Cognitive Development (ABCD) study (N = 9574; mean age = 9.94 years at baseline, SD = .63; 50% girls), the current study took an integrative biopsychosocial approach to explore the longitudinal link between early adolescents' fronto-striatal connectivity and their academic achievement, with attention to the moderating role of parental warmth. Results showed that weaker intrinsic connectivity between the frontoparietal network and the striatum was associated with early adolescents' worse academic achievement over 2 years during early adolescence. Notably, parental warmth moderated the association between fronto-striatal connectivity and academic achievement, such that weaker fronto-striatal connectivity was only predictive of worse academic achievement among early adolescents who experienced low levels of parental warmth. Taken together, the findings demonstrate weaker fronto-striatal connectivity as a risk factor for early adolescents' academic development and highlight parental warmth as a protective factor for academic development among those with weaker connectivity within the inhibitory control system.

Multiple forms of discrimination and obsessive-compulsive disorder: a prospective cohort study

BACKGROUND

Discrimination increases the risk for adverse mental health in minority populations, with studies showing elevated rates of obsessive-compulsive disorder (OCD) in Black adults facing racial discrimination. Yet, there is a lack of longitudinal research on the different forms of discrimination in relation to OCD risk in early adolescence. The objective of this study was to examine the prospective associations between multiple forms of discrimination and OCD in a national sample of U.S. early adolescents.

METHODS

We examined prospective cohort data from Year 2 (2018-2020, ages 10-13) and Year 3 (2019-2021) of the Adolescent Brain Cognitive Development Study (N = 7,983). Multiple logistic regression models were used to analyze associations between Year 2 past 12-month experiences of discrimination (based on race and ethnicity, country of origin, sexual orientation, weight, and combined multi-discrimination) and Year 3 probable OCD (Child Behavior Checklist; based on dichotomized t-score indicating high risk), adjusting for theoretically relevant covariates including age, sex, sexual orientation, race and ethnicity, country of origin, household income, parent education, depression, body mass index category, study site, and Year 2 probable OCD.

RESULTS

Adjusting for all covariates, multi-discrimination (OR = 1.67; 95% CI 1.23, 2.27), racial discrimination (OR = 2.77; 95% CI 1.32, 5.80), sexual orientation discrimination (OR = 2.51; 95% CI 1.11, 5.64), and weight discrimination (OR = 2.51; 95% CI 1.13, 5.59) at Year 2 were prospectively associated with developing probable OCD at Year 3. There were no significant findings for discrimination based on country of origin.

CONCLUSIONS

Early adolescents who have experienced several forms of discrimination have higher odds of developing probable OCD, suggesting the utility of screening for OCD in even younger adolescents who have encountered discrimination. Educators can play a role in guiding adolescents experiencing discrimination to appropriate resources for accessing mental healthcare.

Racial-Ethnic Discrimination and Early Adolescents' Behavioral Problems: The Protective Role of Parental Warmth

OBJECTIVE

The purpose of the study was to investigate the association between discrimination by multiple sources (ie, teachers, students, and other adults) and early adolescents' behavioral problems (ie, internalizing, externalizing, and attention problems), also considering the protective role of parental warmth in the association.

METHOD

Cross-sectional analyses were conducted with 3,245 early adolescents of color obtained from the Adolescent Brain Cognitive Development Study (ABCD Study) at year 1 follow-up (Y1), a large and diverse sample of children (mean age = 9.48 years) in the United States. Racially-ethnically minoritized adolescents reported sources of discrimination, parental warmth, and symptoms of psychopathology. Regression with interaction terms was conducted to investigate the associations among sources of discrimination, parental warmth, and behavioral problems among racially-ethnically minority adolescents. Sensitivity analyses were conducted to examine (1) race/ethnicity and sex/gender variations; (2) whether the associations between different sources of discrimination and behavioral problems were reliably different; and (3) effects of discrimination, parental warmth, and their interplay at Y1 in predicting adolescents' behavioral problems at year 2 follow-up.

RESULTS

Early adolescents experiencing interpersonal racial-ethnic discrimination by multiple sources, including teachers, students, and other adults, reported higher levels of attention, internalizing, and externalizing problems. Parental warmth was protective for the association between interpersonal racial-ethnic discrimination and early adolescents' behavioral problems.

CONCLUSION

Experiencing interpersonal racial-ethnic discrimination from teachers, peers, and other adults is related to heightened attention, internalizing, and externalizing problems among racially-ethnically minoritized early adolescents. Parental warmth may reduce the risk of developing behavioral problems among early adolescents who experience interpersonal racial-ethnic discrimination from students, teachers, and other adults outside of school.

PLAIN LANGUAGE SUMMARY

In this cross sectional analysis of 3,245 early adolescents of color obtained from the Adolescent Brain Cognitive Development (ABCD) Study, the authors found that early adolescents experiencing interpersonal racial-ethnic discrimination from multiple sources, including teachers, students, and other adults, reported higher levels of behavioral problems (ie, internalizing, externalizing, and attention problems). Parental warmth was found to be protective for the association between interpersonal racial-ethnic discrimination and early adolescents' behavioral problems. These findings emphasize the importance of assessing experiences of interpersonal racial-ethnic discrimination among racially-ethnically minoritized early adolescents and contribute to the understanding of parental warmth as a protective factor for early adolescents to cope with such experiences.

The Role of School Engagement in the Link Between Adverse Childhood Experiences and Adolescent Mental Health

PURPOSE

Adverse childhood experiences (ACEs) increase the risk for poor adolescent mental health, yet mediational pathways that connect ACEs with mental health problems remain unaddressed. Our study investigates whether school involvement and disengagement mediate the longitudinal associations between ACEs and adolescent mental health problems.

METHODS

Using data from the longitudinal Adolescent Brain Cognitive Development Study, this study included 7,558 adolescents aged 9-10 years at baseline. ACEs were a cumulative risk score of 21 adverse experiences (e.g., emotional abuse, community violence) reported by parents and youths at baseline or 1-year follow-up. School involvement and disengagement were reported by youths at two-year follow-up. Internalizing and externalizing problems were reported by parents using the Child Behavior Checklist at 3-year follow-up.

RESULTS

A higher ACE score was associated with decreased school involvement (β = -0.08, 95% CI = [-0.10, -0.05]) and increased school disengagement (β = 0.09, 95% CI = [0.06, 0.11]) one year later, and with increased internalizing (β = 0.10, 95% CI = [0.07, 0.12]) and externalizing problems (β = 0.08, 95% CI = [0.06, 0.10]) 2 years later, adjusted for demographics and baseline mental health and school engagement levels. Decreased school involvement and increased disengagement mediated the associations between ACEs with the change in internalizing and externalizing problems over time.

DISCUSSION

The present study highlights the roles of school involvement and disengagement in linking ACEs to worsened mental health outcomes. The findings may inform tailored school-based interventions that address mental health challenges faced by adolescents exposed to ACEs.

Sexual Identity Is Associated With Adverse Childhood Experiences in US Early Adolescents

OBJECTIVE

To determine disparities in adverse childhood experiences (ACEs) by sexual identity in a national cohort of early adolescents.

METHODS

We analyzed cross-sectional data from year 2 of the Adolescent Brain Cognitive Development study (N = 10,934, 2018-20, ages 10-14 years). Disparities in ACE scores across lesbian, gay, or bisexual (LGB), not sure, and heterosexual adolescents were assessed using multinomial logistic regression analyses. Logistic regressions estimated the associations between sexual identity and each individual ACE. Analyses were adjusted for potential confounders.

RESULTS

In adjusted models, LGB adolescents had a higher risk of experiencing 2, 3, or ≥4 ACEs (relative risk ratios [RRR] = 1.57, 95% Confidence Interval (CI) 1.01-2.42), 3 (RR = 1.78, 95% CI 1.100-2.88), or ≥4 ACEs (RRR = 3.20, 95% CI 1.92-5.32), and not sure adolescents had a higher risk of having ≥4 ACEs (RRR = 2.17, 95% CI 1.22-3.87), compared to heterosexual adolescents. LGB and not sure adolescents had higher risks of reporting emotional abuse ("yes" OR = 4.21, 95% CI 1.84-9.61; "maybe" OR = 6.20, 95% CI 2.91-13.19) and parent mental illness ("yes" OR = 1.95, 95% CI 1.48-2.57; "maybe" OR = 1.63, 95% CI 1.21-2.18) compared to heterosexual adolescents.

CONCLUSIONS

LGB adolescents and those questioning their sexual identity were at greater risk of having higher ACE scores, with LGB adolescents experiencing the highest risk of experiencing ACEs. LGB adolescents also had higher odds of reporting emotional and parent mental illness. Recognizing this heightened risk of ACEs in early adolescence is critical for designing clinic and school-based interventions.

Prospective association between screen use modalities and substance use experimentation in early adolescents

BACKGROUND

There are limited large-scale, prospective analyses examining contemporary screen use and substance use experimentation in early adolescents. The current study aimed to determine associations between eight forms of contemporary screen modalities and substance use experimentation one year later in a national cohort of 11-12-year-olds in the United States.

METHODS

The sample consisted of 8006 early adolescents (47.9 % female and 41.6 % racial/ethnic minority) from the prospective cohort data of the Adolescent Brain Cognitive Development (ABCD) Study. Logistic regression analyses were conducted to evaluate the prospective associations between screen time (eight different types and total) in Year 2 and substance use experimentation (alcohol, nicotine, cannabis, any substance use) in Year 3, adjusting for covariates and Year 2 substance use experimentation.

RESULTS

Total screen time was prospectively associated with alcohol, nicotine, and cannabis experimentation. Each additional hour spent on social media (AOR 1.20; 95 % CI 1.14-1.26), texting (AOR 1.18; 95 % CI 1.12-1.24), and video chatting (AOR 1.09; 95 % CI 1.03-1.16) was associated with higher odds of any substance experimentation. Social media use and texting were also associated with higher odds of alcohol, cannabis, and nicotine experimentation; however, television/movies, videos, video games, and the internet were not. Moreover, video chatting was associated with higher odds of cannabis and nicotine experimentation.

CONCLUSIONS

Our findings indicate that digital social connections, such as via social media, texting, and video chatting, are the contemporary screen modalities that are associated with early adolescent substance experimentation. Future research could explore the mechanisms underlying these associations to inform intervention strategies.

Using latent transition analysis to evaluate the impact of perceived threats on emotional and behavioral development

This study used latent transition analysis to examine the stability and change in perceived threats in youth's primary social contexts-neighborhoods, schools, and families-and associations with emotional and behavioral problems when youth transitioned from childhood to adolescence. The sample included 8208 racially and ethnically diverse youth enrolled in the Adolescent Brain Cognitive Development Study (47.4% female, M age_Baseline = 9.83, M age_Timepoint3 = 11.99). Results revealed that while perceived threats in youth's neighborhoods were considerably stable, perceived threats in youth's families fluctuated in relation to stressful life events. Further, subgroups of youth characterized by elevated perceived threat experiences in different contexts showed differential associations with emotional and behavioral problems. Overall, findings highlight the importance of considering the stability of perceived threats to direct appropriate interventions.

Family conflict and less parental monitoring were associated with greater screen time in early adolescence

AIM

The current study investigated the prospective relationships between parental monitoring, family conflict, and screen time across six screen time modalities in early adolescents in the USA.

METHODS

We utilised prospective cohort data of children (ages 10-14 years) from the Adolescent Brain Cognitive Development (ABCD) Study (years baseline to Year 2 of follow-up; 2016-2020; N = 10 757). Adjusted coefficients (B) and 95% confidence intervals (CIs) were estimated using mixed-effect models with robust standard errors.

RESULTS

A higher parental monitoring score was associated with less total screen time (B = -0.37, 95% CI -0.58, -0.16), with the strongest associations being with video games and YouTube videos. Conversely, a higher family conflict score was associated with more total screen time (B = 0.08, 95% CI 0.03, 0.12), with the strongest associations being with YouTube videos, video games, and watching television shows/movies in Years 1 and 2.

CONCLUSION

The current study found that greater parental monitoring was associated with less screen time, while greater family conflict was linked to more screen time. These results may inform strategies to reduce screen time in adolescence, such as improving communication between parents and their children to strengthen family relationships.

Early adolescents' ethnic-racial discrimination and pubertal development: Parents' ethnic-racial identities promote adolescents' resilience

Ethnically and racially underrepresented adolescents are experiencing pubertal development earlier in life than prior cohorts and their White American peers. This early onset of puberty is partly attributable to ethnic-racial discrimination. To contribute to adolescents' resilience and posttraumatic growth in the face of ethnic-racial discrimination, parents' ethnic-racial identities may spill over into their parenting beliefs and practices. Parents who have a sense of belonging with and commitment to their ethnic-racial identities may be aware of discrimination and actively and consistently engage in practices that build supportive home environments to support their children's development in the context of ethnic-racial discrimination. To assess whether parents' ethnic-racial identity commitment predicted adolescents' resilience against ethnic-racial discrimination, we used multiple waves of survey data from adolescent siblings and their parents participating in the Adolescent Brain Cognitive Development study (N-adolescents = 1,651; N-families = 805; 35% Black, 37% Latinx, 3% Asian, 25% other ethnically and racially underrepresented youth; 49% boys, 50% girls, 1% gender nonconforming youth; Mage = 11.49, SD = 0.51). Results indicated that adolescents who experienced more frequent ethnic-racial discrimination than their siblings showed more advanced pubertal development. Parental ethnic-racial identity commitment reduced the relation between discrimination and pubertal development within a family. Results suggest that ethnic-racial identity commitment in parents can protect children when they experience ethnic-racial discrimination. Building on extant propositions related to resilience (Infurna & Luthar, 2018), the present study amplifies the depiction of resilience, yields recommendations for analysis of future research, and provides implications regarding the role of ethnicity-race in familial practices.

Associations between Positive Childhood Experiences (PCEs), Discrimination, and Internalizing/Externalizing in Pre-Adolescents

OBJECTIVE

This study aimed to investigate the relationships between four types of perceived discrimination (based on race and ethnicity, nationality/country of origin, gender identity, weight/body size), individually and cumulatively; positive childhood experiences (PCEs); and behavioral symptoms among pre-adolescent youth.

METHODS

This study was a secondary analysis of data from the Adolescent Brain Cognitive Development (ABCD) Study, a US-based cohort study of pre-adolescent youth in the United States (N = 10,915). Our outcome was emotional/behavioral symptoms measured by the Child Behavior Checklist. Primary exposures were four types of discrimination, a count of 0-5 PCEs, and other adverse childhood experiences (ACEs). Multiple logistic regression models were used to estimate the relationship between perceived discrimination and clinical-range behavioral symptoms, including the role of PCEs and ACEs.

RESULTS

Weight discrimination was the most frequent exposure (n = 643, 5.9%). Race and weight perceived discrimination were associated with clinical-range externalizing and internalizing symptoms, respectively, but these associations were non significant once other ACEs were added to models. Cumulative discrimination was associated with clinical-range Child Behavior Checklist (CBCL) scores, even when accounting for other ACEs (aOR=1.47, 95% CI=1.2-1.8). PCEs slightly reduced the strength of this relationship and were independently associated with reduced symptoms (aOR=0.82, 95% CI=0.72-0.93).

CONCLUSIONS

Results of this national study suggest cumulative discrimination can exert emotional/behavioral health harm among youth. PCEs were independently associated with reduced behavioral symptoms. There is a need for further research on how to prevent discrimination and bolster PCEs by targeting upstream social inequities in communities.

Working memory related brain-behavior associations in the context of socioeconomic and psychosocial deprivation

Burgeoning neuroimaging research documents the associations between working memory (WM)-associated neural and behavioral responses. However, these associations have yielded small and inconsistent effect sizes. We hypothesize that one reason for the weakened brain-behavior associations stems from different environmental contexts. Specifically, little research has examined how exposure to adverse rearing environments accounts for variability in brain-behavior relations. Deprivation, characterized by an absence of cognitive and positive social stimulation, has been shown to compromise children's neurocognitive development. Hence, informed by an ecological approach to developmental neuroscience, the present study aims to investigate if psychosocial and socioeconomic deprivation serves as moderators in the associations between neural responses and behaviors during a WM task. Using data from the Adolescent Brain Cognitive Development study (N = 11, 878, Mage = 9.48, 47.8% female, 52.0% White), we found that psychosocial, but not socioeconomic deprivation, significantly attenuated the positive association between WM-related neural activation within the frontoparietal network and attendant behavioral performance. Specifically, children exposed to higher levels of psychosocial deprivation exhibited weaker brain-behavior relations during a WM task. This finding suggests that a certain level of neural response during cognitive tasks may correspond to different levels of behavioral performance depending on children's rearing environment, highlighting the importance of contextual factors in understanding the brain and cognitive development.

Longitudinal panel networks of risk and protective factors for early adolescent suicidality in the ABCD sample

Rates of youth suicidal thoughts and behaviors (STBs) are rising, and younger age at onset increases vulnerability to negative outcomes. However, few studies have investigated STBs in early adolescence (ages 10-13), and accurate prediction of youth STBs remains poor. Network analyses that can examine pairwise associations between many theoretically relevant variables may identify complex pathways of risk for early adolescent STBs. The present study applied longitudinal network analysis to examine interrelations between STBs and several previously identified risk and protective factors. Data came from 9,854 youth in the Adolescent Brain Cognitive Development Study cohort (Mage = 9.90 ± .62 years, 63% white, 53% female at baseline). Youth and their caregivers completed an annual measurement battery between ages 9-10 through 11-12 years. Panel Graphical Vector Autoregressive models evaluated associations between STBs and several mental health symptoms, socioenvironmental factors, life stressors, and substance use. In the contemporaneous and between-subjects networks, direct associations were observed between STBs and internalizing symptoms, substance use, family conflict, lower parental monitoring, and lower school protective factors. Potential indirect pathways of risk for STBs were also observed. Age-specific interventions may benefit from prioritizing internalizing symptoms and early substance use, as well as promoting positive school and family support.

Associations of Contemporary Screen Time Modalities With Early Adolescent Nutrition

OBJECTIVE

To determine the associations between screen time across several contemporary screen modalities (eg, television, video games, text, video chat, social media) and adherence to the Mediterranean-DASH (dietary approaches to stop hypertension) intervention for neurodegenerative delay (MIND) diet in early adolescents.

METHODS

We analyzed data from the Adolescent Brain Cognitive Development study of 9 to 12-year-old adolescents in the United States. Multiple linear regression analyses examined the relationship between self-reported screen time measures at baseline (year 0) and the 1-year follow-up (year 1) and caregiver-reported nutrition assessments at year 1, providing a prospective and cross-sectional analysis. Cross-sectional marginal predicted probabilities were calculated.

RESULTS

In a sample of 8267 adolescents (49.0% female, 56.9% white), mean age 10 years, total screen time increased from 3.80 h/d at year 0 to 4.61 h/d at year 1. Change in total screen time from year 0 and year 1 was associated with lower nutrition scores at year 1.

PROSPECTIVE

Screen time spent on television, video games, and videos at year 0 was associated with lower nutrition scores at year 1. Cross-sectional: Screen time spent on television, video games, videos, texting, and social media at year 1 was associated with lower MIND diet scores at year 1.

CONCLUSIONS

Both traditional (television) and several contemporary modalities of screen time are associated, prospectively and cross-sectionally, with lower overall diet quality, measured by the MIND diet nutrition score, in early adolescents. Future studies should further explore the effect of rising digital platforms and media on overall adolescent nutrition.

Data-driven, generalizable prediction of adolescent sleep disturbances in the multisite Adolescent Brain Cognitive Development Study

STUDY OBJECTIVES

Sleep disturbances are common in adolescence and associated with a host of negative outcomes. Here, we assess associations between multifaceted sleep disturbances and a broad set of psychological, cognitive, and demographic variables using a data-driven approach, canonical correlation analysis (CCA).

METHODS

Baseline data from 9093 participants from the Adolescent Brain Cognitive Development (ABCD) Study were examined using CCA, a multivariate statistical approach that identifies many-to-many associations between two sets of variables by finding combinations for each set of variables that maximize their correlation. We combined CCA with leave-one-site-out cross-validation across ABCD sites to examine the robustness of results and generalizability to new participants. The statistical significance of canonical correlations was determined by non-parametric permutation tests that accounted for twin, family, and site structure. To assess the stability of the associations identified at baseline, CCA was repeated using 2-year follow-up data from 4247 ABCD Study participants.

RESULTS

Two significant sets of associations were identified: (1) difficulty initiating and maintaining sleep and excessive daytime somnolence were strongly linked to nearly all domains of psychopathology (r2 = 0.36, p < .0001); (2) sleep breathing disorders were linked to BMI and African American/black race (r2 = 0.08, p < .0001). These associations generalized to unseen participants at all 22 ABCD sites and were replicated using 2-year follow-up data.

CONCLUSIONS

These findings underscore interwoven links between sleep disturbances in early adolescence and psychological, social, and demographic factors.

Childhood adversity is associated with reduced BOLD response in inhibitory control regions amongst preadolescents from the ABCD study

Adolescence is characterized by dynamic neurodevelopment, which poses opportunities for risk and resilience. Adverse childhood experiences (ACEs) confer additional risk to the developing brain, where ACEs have been associated with alterations in functional magnetic resonance imaging (fMRI) BOLD signaling in brain regions underlying inhibitory control. Socioenvironmental factors like the family environment may amplify or buffer against the neurodevelopmental risks associated with ACEs. Using baseline to Year 2 follow-up data from the Adolescent Brain Cognitive Development (ABCD) Study, the current study examined how ACEs relate to fMRI BOLD signaling during successful inhibition on the Stop Signal Task in regions associated with inhibitory control and examined whether family conflict levels moderated that relationship. Results showed that greater ACEs were associated with reduced BOLD response in the right opercular region of the inferior frontal gyrus and bilaterally in the pre-supplementary motor area, which are key regions underlying inhibitory control. Further, greater BOLD response was correlated with less impulsivity behaviorally, suggesting reduced activation may not be behaviorally adaptive at this age. No significant two or three-way interactions with family conflict levels or time were found. Findings highlight the continued utility of examining the relationship between ACEs and neurodevelopmental outcomes and the importance of intervention/prevention of ACES.

Probing the digital exposome: associations of social media use patterns with youth mental health

Recently, the U.S. Surgeon General issued an advisory highlighting the lack of knowledge about the safety of ubiquitous social media use on adolescent mental health. For many youths, social media use can become excessive and can contribute to frequent exposure to adverse peer interactions (e.g., cyberbullying, and hate speech). Nonetheless, social media use is complex, and although there are clear challenges, it also can create critical new avenues for connection, particularly among marginalized youth. In the current project, we leverage a large nationally diverse sample of adolescents from the Adolescent Brain Cognitive Development (ABCD) Study assessed between 2019-2020 (N = 10,147, M age = 12.0, 48% assigned female at birth, 20% Black, 20% Hispanic) to test the associations between specific facets of adolescent social media use (e.g., type of apps used, time spent, addictive patterns of use) and overall mental health. Specifically, a data-driven exposome-wide association was applied to generate digital exposomic risk scores that aggregate the cumulative burden of digital risk exposure. This included general usage, cyberbullying, having secret accounts, problematic/addictive use behavior, and other factors. In validation models, digital exposomic risk explained substantial variance in general child-reported psychopathology, and a history of suicide attempt, over and above sociodemographics, non-social screentime, and non-digital adversity (e.g., abuse, poverty). Furthermore, differences in digital exposomic scores also shed insight into mental health disparities, among youth of color and sexual and gender minority youth. Our work using a data-driven approach supports the notion that digital exposures, in particular social media use, contribute to the mental health burden of US adolescents.

Revisiting Associations Among Parent and Adolescent Religiosity and Early Adolescent Suicide Risk in the United States

The contributions of religion to reduced suicide risk have been studied in adults and adolescents, though to our knowledge no comprehensive investigation has been conducted in early adolescents, at a time coinciding with emergence of suicide risk trajectories. In this largest study to date on this topic, we aimed to characterise the contributions of various measures of "private" and "public" religiosity to early adolescent suicide ideation (SI) and suicide attempt (SA) histories using information from a large, epidemiologically informed U.S. sample of adolescents (N = 7068; mean age = 12.89 years, 47% female) and their parents. In all youth, parent-reported adolescent religious importance was associated with reduced odds of SA (OR = 0.75, CI = 0.61-0.92, P = .005). Muslim youth were more likely (OR = 1.52, CI = 1.02-2.22, P = .033), and Catholic youth were less likely (OR = 0.80, CI = 0.67-0.95, P = .014), to report SI. A variety of sex differences were noted, with significant protective associations of adolescent self-reported religiosity on SI and SA, religious service attendance on SI, and religious importance on SI, in female-but not male-youth; and significant protective associations of religious importance on SA in male-but not female-youth. Against expectations, there was no evidence that parent religiosity moderated the link between youth religiosity and SI or SA. These results shed light on the roles of cultural and familial context in youth suicide risk, which may ultimately be targeted in screening and interventional approaches.

Recommendations for the responsible use and communication of race and ethnicity in neuroimaging research

The growing availability of large-population human biomedical datasets provides researchers with unique opportunities to conduct rigorous and impactful studies on brain and behavioral development, allowing for a more comprehensive understanding of neurodevelopment in diverse populations. However, the patterns observed in these datasets are more likely to be influenced by upstream structural inequities (that is, structural racism), which can lead to health disparities based on race, ethnicity and social class. This paper addresses the need for guidance and self-reflection in biomedical research on conceptualizing, contextualizing and communicating issues related to race and ethnicity. We provide recommendations as a starting point for researchers to rethink race and ethnicity choices in study design, model specification, statistical analysis and communication of results, implement practices to avoid the further stigmatization of historically minoritized groups, and engage in research practices that counteract existing harmful biases.

Threat experiences moderate the link between hippocampus volume and depression symptoms prospectively in adolescence

Identifying neuroimaging risk markers for depression has been an elusive goal in psychopathology research. Despite this, smaller hippocampal volume has emerged as a potential risk marker for depression, with recent research suggesting this association is moderated by family income. The current pre-registered study aimed to replicate and extend these findings by examining the moderating role of family income and three dimensions of environmental experience on the link between hippocampus volume and later depression. Data were drawn from the Adolescent Brain Cognitive Development (ABCD) study and were comprised of 6693 youth aged 9-10 years at baseline. Results indicated that psychosocial threat moderated the association between right hippocampus volume and depression symptoms two years later, such that a negative association was evident in low-threat environments (std. beta=0.15, 95% CI [0.05, 0.24]). This interaction remained significant when baseline depression symptoms were included as a covariate, though only in youth endorsing 1 or more depression symptoms at baseline (β = 0.13, 95% CI = [0.03, 0.22]). These results suggest that hippocampus volume may not be a consistent correlate of depression symptoms in high risk environments and emphasize the importance of including measures of environmental heterogeneity when seeking risk markers for depression.

Making Connections: Neurodevelopmental Changes in Brain Connectivity After Adverse Experiences in Early Adolescence

Adverse childhood experiences have been linked to detrimental mental health outcomes in adulthood. This study investigates a potential neurodevelopmental pathway between adversity and mental health outcomes: brain connectivity. We used data from the prospective, longitudinal Adolescent Brain Cognitive Development (ABCD) study (N ≍ 12.000, participants aged 9-13 years, male and female) and assessed structural brain connectivity using fractional anisotropy (FA) of white matter tracts. The adverse experiences modeled included family conflict and traumatic experiences. K-means clustering and latent basis growth models were used to determine subgroups based on total levels and trajectories of brain connectivity. Multinomial regression was used to determine associations between cluster membership and adverse experiences. The results showed that higher family conflict was associated with higher FA levels across brain tracts (e.g., t (3) = -3.81, β = -0.09, p bonf = 0.003) and within the corpus callosum (CC), fornix, and anterior thalamic radiations (ATR). A decreasing FA trajectory across two brain imaging timepoints was linked to lower socioeconomic status and neighborhood safety. Socioeconomic status was related to FA across brain tracts (e.g., t (3) = 3.44, β = 0.10, p bonf = 0.01), the CC and the ATR. Neighborhood safety was associated with FA in the Fornix and ATR (e.g., t (1) = 3.48, β = 0.09, p bonf = 0.01). There is a complex and multifaceted relationship between adverse experiences and brain development, where adverse experiences during early adolescence are related to brain connectivity. These findings underscore the importance of studying adverse experiences beyond early childhood to understand lifespan developmental outcomes.

Alcohol Use Disorder Polygenic Risk Scores and Trajectories of Early Adolescent Externalizing Behaviors: Examining the Role of Parenting and Family Conflict in the Racially/Ethnically Diverse ABCD Sample

This study examined the independent and interactive effects of alcohol use disorder genome-wide polygenic scores (AUD-PGS) and parenting and family conflict on early adolescent externalizing behaviors. Data were drawn from White (N = 6181, 46.9% female), Black/African American (N = 1784, 50.1% female), and Hispanic/Latinx (N = 2410, 48.0% female) youth from the adolescent brain cognitive development Study (ABCD). Parents reported on youth externalizing behaviors at baseline (T1, age 9/10), 1-year (T2, age 10/11) and 2-year (T3, age 11/12) assessments. Youth reported on parenting and family environment at T1 and provided saliva or blood samples for genotyping. Results from latent growth models indicated that in general externalizing behaviors decreased from T1 to T3. Across all groups, higher family conflict was associated with more externalizing behaviors at T1, and we did not find significant associations between parental monitoring and early adolescent externalizing behaviors. Parental acceptance was associated with lower externalizing behaviors among White and Hispanic youth, but not among Black youth. Results indicated no significant main effect of AUD-PGS nor interaction effect between AUD-PGS and family variables on early adolescent externalizing behaviors. Post hoc exploratory analysis uncovered an interaction between AUD-PGS and parental acceptance such that AUD-PGS was positively associated with externalizing rule-breaking behaviors among Hispanic youth, but only when parental acceptance was very low. Findings highlight the important role of family conflict and parental acceptance in externalizing behaviors among early adolescents, and emphasize the need to examine other developmental pathways underlying genetic risk for AUD across diverse populations.

Generalizable prediction of childhood ADHD symptoms from neurocognitive testing and youth characteristics

Childhood attention-deficit/hyperactivity disorder (ADHD) symptoms are believed to result from disrupted neurocognitive development. However, evidence for the clinical and predictive value of neurocognitive assessments in this context has been mixed, and there have been no large-scale efforts to quantify their potential for use in generalizable models that predict individuals' ADHD symptoms in new data. Using data drawn from the Adolescent Brain Cognitive Development Study (ABCD), a consortium that recruited a diverse sample of over 10,000 youth (ages 9-10 at baseline) across 21 U.S. sites, we develop and test cross-validated machine learning models for predicting youths' ADHD symptoms using neurocognitive abilities, demographics, and child and family characteristics. Models used baseline demographic and biometric measures, geocoded neighborhood data, youth reports of child and family characteristics, and neurocognitive tests to predict parent- and teacher-reported ADHD symptoms at the 1-year and 2-year follow-up time points. Predictive models explained 15-20% of the variance in 1-year ADHD symptoms for ABCD Study sites that were left out of the model-fitting process and 12-13% of the variance in 2-year ADHD symptoms. Models displayed high generalizability across study sites and trivial loss of predictive power when transferred from training data to left-out data. Features from multiple domains contributed meaningfully to prediction, including neurocognition, sex, self-reported impulsivity, parental monitoring, and screen time. This work quantifies the information value of neurocognitive abilities and other child characteristics for predicting ADHD symptoms and provides a foundational method for predicting individual youths' symptoms in new data across contexts.

Associations Between Gender Nonconformity, School Environments, Family Conflict, and Emotional and Behavioral Health Among Children Ages 10-11

PURPOSE

In youth, gender nonconformity (GNC; gender expression that differs from stereotypes based on assigned sex at birth) is associated with a higher likelihood of peer and caregiver victimization and rejection. However, few studies have examined the relationship between GNC, overall family conflict, perceptions of school environment, and emotional and behavioral health problems among children ages 10-11.

METHODS

The Adolescent Brain Cognitive Development Study data release 3.0 was used (n = 11,068; 47.9% female). A path analysis was used to examine whether school environment and family conflict, mediated the relationship between GNC and behavioral and emotional health outcomes.

RESULTS

We found significant mediation of the relationship between GNC and behavioral and emotional health by school environment a2b2 = .20, 95% CI [0.13, 0.27] and family conflict a1b1 = 0.34, 95% CI [0.25, 0.42].

DISCUSSION

Our results suggest that youth who present as gender nonconforming experience elevated family conflict, poorer perceptions of their school environment and elevated behavioral and emotional health problems. Further, the relationship between GNC and elevated emotional and behavioral health problems was mediated by perceptions of school environment and family conflict. Clinical and policy suggestions to improve environments and outcomes for youth who present as gender nonconforming are discussed.

Caregiver monitoring, but not caregiver warmth, is associated with general cognition in two large sub-samples of youth

Individual differences in cognitive abilities emerge early during development, and children with poorer cognition are at increased risk for adverse outcomes as they enter adolescence. Caregiving plays an important role in supporting cognitive development, yet it remains unclear how specific types of caregiving behaviors may shape cognition, highlighting the need for large-scale studies. In the present study, we characterized replicable yet specific associations between caregiving behaviors and cognition in two large sub-samples of children ages 9-10 years old from the Adolescent Brain Cognitive Development Study® (ABCD). Across both discovery and replication sub-samples, we found that child reports of caregiver monitoring (supervision or regular knowledge of the child's whereabouts) were positively associated with general cognition abilities, after covarying for age, sex, household income, neighborhood deprivation, and parental education. This association was specific to the type of caregiving behavior (caregiver monitoring, but not caregiver warmth), and was most strongly associated with a broad domain of general cognition (but not executive function or learning/memory). Additionally, we found that caregiver monitoring partially mediated the association between household income and cognition, furthering our understanding of how socioeconomic disparities may contribute to disadvantages in cognitive development. Together, these findings underscore the influence of differences in caregiving behavior in shaping youth cognition. RESEARCH HIGHLIGHTS: Caregiver monitoring, but not caregiver warmth, is associated with cognitive performance in youth Caregiver monitoring partially mediates the association between household income and cognition Results replicated across two large matched samples from the Adolescent Brain Cognitive Development Study® (ABCD).

Sexual Orientation Disparities in Early Adolescent Sleep: Findings from the Adolescent Brain Cognitive Development Study

Purpose: The purpose of this study was to examine associations between sexual minority status (e.g., gay or bisexual) and sleep problems in a demographically diverse, national sample of U.S. early adolescents. Methods: We analyzed cross-sectional data from the Adolescent Brain Cognitive Development Study (Year 2, 2018-2020) to estimate associations between sexual orientation and sleep problems or disturbance, adjusting for confounders and testing potential mediators (depressive problems, stress problems, family conflict, and parental monitoring). Results: In a sample of 8563 adolescents 10- to 14-years-old, 4.4% identified as sexual minority individuals. Sexual minority status was associated with self-reported trouble falling or staying asleep (risk ratio [RR] = 2.24, 95% confidence interval [CI] = 1.88-2.68) and caregiver-reported sleep disturbance (RR = 1.50, 95% CI = 1.29-1.75). The association between sexual minority status and trouble falling or staying asleep was partially mediated by greater depressive problems, more family conflict, and less parental monitoring, whereas the association between sexual minority status and caregiver-reported sleep disturbance was partially mediated by greater depressive problems, higher stress, and greater family conflict. Conclusions: Our results indicate that sexual minority status may be linked to sleep disturbance in early adolescence. Depressive problems, stress, family conflict, and less parental monitoring partially mediate disparities in sleep health for sexual minority youth. Future research could test interventions to promote family and caregiver acceptance and mental health support for sexual minority youth to improve their sleep and other health outcomes.

Mediating effect of pubertal stages on the family environment and neurodevelopment: An open-data replication and multiverse analysis of an ABCD Study®

Increasing evidence demonstrates that environmental factors meaningfully impact the development of the brain (Hyde et al., 2020; McEwen and Akil, 2020). Recent work from the Adolescent Brain Cognitive Development (ABCD) Study® suggests that puberty may indirectly account for some association between the family environment and brain structure and function (Thijssen et al., 2020). However, a limited number of large studies have evaluated what, how, and why environmental factors impact neurodevelopment. When these topics are investigated, there is typically inconsistent operationalization of variables between studies which may be measuring different aspects of the environment and thus different associations in the analytic models. Multiverse analyses (Steegen et al., 2016) are an efficacious technique for investigating the effect of different operationalizations of the same construct on underlying interpretations. While one of the assets of Thijssen et al. (2020) was its large sample from the ABCD data, the authors used an early release that contained 38% of the full ABCD sample. Then, the analyses used several 'researcher degrees of freedom' (Gelman and Loken, 2014) to operationalize key independent, mediating and dependent variables, including but not limited to, the use of a latent factor of preadolescents' environment comprised of different subfactors, such as parental monitoring and child-reported family conflict. While latent factors can improve reliability of constructs, the nuances of each subfactor and measure that comprise the environment may be lost, making the latent factors difficult to interpret in the context of individual differences. This study extends the work of Thijssen et al. (2020) by evaluating the extent to which the analytic choices in their study affected their conclusions. In Aim 1, using the same variables and models, we replicate findings from the original study using the full sample in Release 3.0. Then, in Aim 2, using a multiverse analysis we extend findings by considering nine alternative operationalizations of family environment, three of puberty, and five of brain measures (total of 135 models) to evaluate the impact on conclusions from Aim 1. In these results, 90% of the directions of effects and 60% of the p-values (e.g. p > .05 and p < .05) across effects were comparable between the two studies. However, raters agreed that only 60% of the effects had replicated. Across the multiverse analyses, there was a degree of variability in beta estimates across the environmental variables, and lack of consensus between parent reported and child reported pubertal development for the indirect effects. This study demonstrates the challenge in defining which effects replicate, the nuance across environmental variables in the ABCD data, and the lack of consensus across parent and child reported puberty scales in youth.

Genetic risk of AUDs and childhood impulsivity: Examining the role of parenting and family environment

This study examined the independent and interactive effects of genetic risk for alcohol use disorder (AUD), parenting behaviors, and family environment on childhood impulsivity. Data were drawn from White (n = 5,991), Black/African American (n = 1,693), and Hispanic/Latino (n = 2,118) youth who completed the baseline assessment (age 9-10) and had genotypic data available from the Adolescent Brain Cognitive Development Study. Participants completed questionnaires and provided saliva or blood samples for genotyping. Results indicated no significant main effects of AUD genome-wide polygenic scores (AUD-PRS) on childhood impulsivity as measured by the UPPS-P scale across racial/ethnic groups. In general, parental monitoring and parental acceptance were associated with lower impulsivity; family conflict was associated with higher impulsivity. There was an interaction effect between AUD-PRS and family conflict, such that family conflict exacerbated the association between AUD-PRS and positive urgency, only among Black/African American youth. This was the only significant interaction effect detected from a total of 45 tests (five impulsivity dimensions, three subsamples, and three family factors), and thus may be a false positive and needs to be replicated. These findings highlight the important role of parenting behaviors and family conflict in relation to impulsivity among children.

Intersection between social inequality and emotion regulation on emerging adult cannabis use

Emerging adulthood (EA; ages 18-25) is characterized by socioemotional and neurodevelopmental challenges. Cannabis is a widely used substance among EAs, and hazardous use may increase risk for sustained use patterns and related health consequences. Research shows differential increases in hazardous use by objective as well as subjective measures of social inequality, with more concerning trajectories for youth with greater experiences of social inequality. Learning how to flexibly monitor and modify emotions in proactive ways (i.e., emotion regulation) is a central developmental task navigated during the EA window. Challenges to and with emotion regulation processes can contribute to the emergence of mental health symptoms during EA, including hazardous cannabis use. In this perspective, we highlight emotion dysregulation and social inequality as two critical factors that interact to either buffer against or exacerbate cannabis use during the EA period, noting critical gaps in the literature that merit additional research. We recommend novel methods and longitudinal designs to help clarify how dynamic cognition-emotion interplay predicts trajectories of negative emotional experiences and cannabis use in EA.

A practical guide for researchers and reviewers using the ABCD Study and other large longitudinal datasets

As the largest longitudinal study of adolescent brain development and behavior to date, the Adolescent Brain Cognitive Development (ABCD) Study® has provided immense opportunities for researchers across disciplines since its first data release in 2018. The size and scope of the study also present a number of hurdles, which range from becoming familiar with the study design and data structure to employing rigorous and reproducible analyses. The current paper is intended as a guide for researchers and reviewers working with ABCD data, highlighting the features of the data (and the strengths and limitations therein) as well as relevant analytical and methodological considerations. Additionally, we explore justice, equity, diversity, and inclusion efforts as they pertain to the ABCD Study and other large-scale datasets. In doing so, we hope to increase both accessibility of the ABCD Study and transparency within the field of developmental cognitive neuroscience.
