Balancing Data Quality and Bias: Investigating Functional Connectivity Exclusions in the Adolescent Brain Cognitive Development℠ (ABCD Study) Across Quality Control Pathways.

Analysis of resting state fMRI (rs-fMRI) typically excludes images substantially degraded by subject motion. However, data quality, including degree of motion, relates to a broad set of participant characteristics, particularly in pediatric neuroimaging. Consequently, when planning quality control (QC) procedures researchers must balance data quality concerns against the possibility of biasing results by eliminating data.

Traumatic and Adverse Childhood Experiences and Developmental Differences in Psychiatric Risk.

Importance: While adverse childhood experiences (ACEs) are known to impart significant risk for negative mental health and cognitive outcomes in youth, translation of ACE scores into clinical intervention is limited by poor specificity in predicting negative outcomes. This work expands on the ACE framework using a data-driven approach to identify 8 different forms of traumatic and adverse childhood experiences (TRACEs) and reveal their differential associations with psychiatric risk and cognition across development.

Objective: Building upon the traditional ACEs model, this study aimed to characterize unique components of commonly co-occurring TRACEs and to examine moderation of longitudinal change in mental health and cognitive development during adolescence.

Diverging Effects of Violence Exposure and Psychiatric Symptoms on Amygdala-Prefrontal Maturation During Childhood and Adolescence.

Background: Violence exposure during childhood and adolescence is associated with increased prevalence and severity of psychopathology. Neurobiological correlates suggest that abnormal maturation of emotion-related brain circuitry, such as the amygdala-prefrontal cortex (PFC) circuit, may underlie the development of psychiatric symptoms after exposure. However, it remains unclear how amygdala-PFC circuit maturation is related to psychiatric risk in the context of violence.

Parent Psychopathology and Behavioral Effects on Child Brain-Symptom Networks in the ABCD Study.

Objective: Parents play a notable role in the development of child psychopathology. In this study, we investigated the role of parent psychopathology and behaviors on child brain-symptom networks to understand the role of intergenerational transmission of psychopathology. Few studies have documented the interaction of child psychopathology, parent psychopathology, and child neuroimaging.

A systematic review of childhood maltreatment and resting state functional connectivity.

Resting-state functional connectivity (rsFC) has the potential to shed light on how childhood abuse and neglect relates to negative psychiatric outcomes. However, a comprehensive review of the impact of childhood maltreatment on the brain's resting state functional organization has not yet been undertaken. We systematically searched rsFC studies in children and youth exposed to maltreatment.

Neurogenetic mechanisms of risk for ADHD: Examining associations of polygenic scores and brain volumes in a population cohort.

Background: ADHD polygenic scores (PGSs) have been previously shown to predict ADHD outcomes in several studies. However, ADHD PGSs are typically correlated with ADHD but not necessarily reflective of causal mechanisms. More research is needed to elucidate the neurobiological mechanisms underlying ADHD.

Editorial: White Matter and Youth Psychopathology: Case Closed?

Psychiatric problems in children (and adults) are reflected in brain networks. Remarkable advances in functional magnetic resonance imaging continue to evince a bidirectional relation between the functional flow of activation across the brain and the etiology of psychiatric disorders. This work is analogous to that of a city engineer surveying traffic to understand flow patterns, efficiency, congestion, and even the influence of city-wide conditions (eg, snowfall).

Sex-based variations of prefrontal structure and longitudinal symptoms in pediatric posttraumatic stress disorder.

Background: Pediatric posttraumatic stress disorder (pPTSD) is more than three times as likely to develop in trauma-exposed female youth than males. Despite the staggering sex differences in the prevalence rates of pPTSD and symptom expression, relatively little is known about the underlying biomarkers of these sex-based variations in pPTSD as compared to typically development.

Methods: The Youth PTSD study recruited 97 youth, ages of 7 and 18, to undergo comprehensive clinical assessments and T1-weighted MRI to evaluate the extent to which sex can explain PTSD-related variations in brain structure.

Differential Patterns of Delayed Emotion Circuit Maturation in Abused Girls With and Without Internalizing Psychopathology.

Objective: Childhood abuse represents one of the most potent risk factors for developing psychopathology, especially in females. Evidence suggests that exposure to early-life adversity may be related to advanced maturation of emotion processing neural circuits. However, it remains unknown whether abuse is related to early circuit maturation and whether maturation patterns depend on the presence of psychopathology.

Pediatric PTSD is characterized by age- and sex-related abnormalities in structural connectivity.

Pediatric post-traumatic stress disorder (pPTSD) is a prevalent and pervasive form of mental illness comprising a disparate constellation of psychiatric symptoms. Emerging evidence suggests that pPTSD may be characterized by alterations in functional networks traversing the brain. Yet, little is known about pathological changes in the structural tracts underlying functional connectivity.

Translating the neuroscience of adverse childhood experiences to inform policy and foster population-level resilience.

Imaging methods have elucidated several neurobiological correlates of traumatic and adverse experiences in childhood. This knowledge base may foster the development of programs and policies that aim to build resilience and adaptation in children and youth facing adversity. Translation of this research requires both effective and accurate communication of the science.

Childhood exposure to interpersonal violence is associated with greater transdiagnostic integration of psychiatric symptoms.

Background: Childhood exposure to interpersonal violence (IPV) may be linked to distinct manifestations of mental illness, yet the nature of this change remains poorly understood. Network analysis can provide unique insights by contrasting the interrelatedness of symptoms underlying psychopathology across exposed and non-exposed youth, with potential clinical implications for a treatment-resistant population. We anticipated marked differences in symptom associations among IPV-exposed youth, particularly in terms of 'hub' symptoms holding outsized influence over the network, as well as formation and influence of communities of highly interconnected symptoms.

Developmental Variation in Amygdala Volumes: Modeling Differences Across Time, Age, and Puberty.

Background: There is evidence that the amygdala undergoes extensive development. The exact nature of this change remains less clear, with evidence suggesting linear, curvilinear, and null effects. The aim of this study was the identification of a normative reference of left and right amygdala development by parceling variance into separate effects of age and longitudinal growth.

The Role of Emotion Processing in the Association between Parental Discipline and Adolescent Socio-Emotional Development.

This research investigated whether biases in processing threatening emotional cues operate as an indirect pathway through which parental harsh discipline is associated with adolescent socio-emotional functioning. Participants were 192 adolescents (M age = 12.4), and their parents assessed over two years.

Editorial: The Preschool Emotional Brain.

There is broad consensus that children's ability to regulate emotion, particularly negative affect, can have enormous implications for the cascading processes underlying social and emotional development. With the burgeoning autonomy of toddlerhood comes a rudimentary understanding of the varieties of emotional experience, and initial awareness that a child's actions can augment or attenuate the intensity of those experiences. Successful forays into emotion regulation are crucial for healthy psychological development, allowing children to accommodate life's difficulties by purposefully altering their emotional state (ie, coping) when necessary.

Heart rate variability and anxious arousal: Unique relations with sleep-related problems in stress-exposed adolescents.

Sleep-related problems (SRPs) among adolescents are a growing concern. Theory and research suggest that emotional arousal may have cyclical relation with SRPs, but whether emotional dysregulation plays a role is not clear. We investigated associations between two physiological indices of emotion regulation (video baseline heart rate variability and change in heart rate variability to a stressor) and SRPs in a sample of 80 adolescents (ages 11-17 years; 51% female; 37.

Susceptibility and resilience to cyber threat: Findings from a scenario decision program to measure secure and insecure computing behavior.

Interest in the individual differences underlying end user computer security behavior has led to the development of a multidisciplinary field of research known as behavioral information security. An important gap in knowledge and the motivation for this research is the development of ways to measure secure and insecure cyber behavior for research and eventually practice. Here we report a study designed to develop a technique for assessing secure and insecure cyber behavior for broad research use.

Annual Research Review: Pediatric posttraumatic stress disorder from a neurodevelopmental network perspective.

Background: Experiencing traumatic stress is common and may lead to posttraumatic stress disorder (PTSD) in a number of children and adolescents. Research using advanced imaging techniques is beginning to elucidate some of the neurobiological correlates of the traumatic stress response in youth.

Methods: This paper summarizes the emerging network perspective of PTSD symptoms and reviews brain imaging research emphasizing structural and functional connectivity studies that employ magnetic resonance imaging techniques in pediatric samples.

The Network Structure of Posttraumatic Stress Symptoms in Children and Adolescents Exposed to Disasters.

Objective: To evaluate current theoretical assumptions about the nature of pediatric posttraumatic stress disorder (PTSD) by examining the network structure of PTSD in a sample of youth exposed to disasters and testing for age differences. Network analysis provides the opportunity to identify "central" symptoms that might hold an outsized influence over others and are important targets for research and treatment. The authors hypothesized that particular symptoms would exhibit greater influence over others.

The Brief Peer Conflict Scale: Psychometric Properties Among a Sample of Incarcerated Male Juvenile Offenders.

Aggression can be considered a multidimensional construct that influences various forms of antisocial behavior, including juvenile delinquency and conduct problems. The aim of the present study was to assess the psychometric properties of the Brief Peer Conflict Scale-20 item version (PCS-20) among a Portuguese forensic sample (N = 192) of incarcerated male juvenile offenders ( M = 16.62 years; SD = 1.

Identifying mental health issues in detained youth: Testing the structure and invariance of the Massachusetts Youth Screening Inventory-Version 2 (MAYSI-2).

This study examined the factor structure of the Massachusetts Youth Screening Instrument-Version 2 (MAYSI-2), a brief self-report measure designed to flag clinically significant mental health needs among youth entering the juvenile justice system. Participants were 981 detained youth in the southeastern United States (mean age = 14.58 years; SD = 1.

Existential Anxiety Among Adolescents Exposed to Disaster: Linkages Among Level of Exposure, PTSD, and Depression Symptoms.

Exposure to natural disasters can be highly traumatic and have a detrimental effect on youth mental health by threatening the satisfaction of basic human needs and goals. Recent research in adults suggests that exposure to disasters may exacerbate existential anxiety about the meaning of life. The current study expands this investigation to adolescents, who may be particularly vulnerable to the negative effects of disaster.

Agreement in Youth-Parent Perceptions of Parenting Behaviors: A Case for Testing Measurement Invariance in Reporter Discrepancy Research.

While conventional wisdom suggests that parents and their adolescent offspring will often disagree, the nature of discrepancies in informant reports of parenting behaviors is still unclear. This article suggests testing measurement invariance in an effort to clarify if discrepancies in informant scores reflect true differences in perspectives on the same construct, or if the instrument is simply not measuring the same construct across parents and youth. The study provides an example by examining invariance and discrepancy across child, adolescent, and parent reports on the Alabama Parenting Questionnaire.
