Strengthening through adversity: The hormesis model in developmental psychopathology.

Background: Employing a developmental psychopathology framework, we tested the utility of the hormesis model in examining the strengthening of children and youth through limited levels of adversity in relation to internalizing and externalizing outcomes within a brain-by-development context.

Methods: Analyzing data from the Adolescent Brain and Cognitive Development study ( = 11,878), we formed latent factors of threat, deprivation, and unpredictability. We examined linear and nonlinear associations between adversity dimensions and youth psychopathology symptoms and how change of resting-state functional connectivity (rsFC) in the default mode network (DMN) from Time 1 to Time 5 moderates these associations.

Person-centered methods to advance developmental psychopathology.

Dante Cicchetti's remarkable contributions to the field of developmental psychopathology include the advancement of key principles such as the interplay of typical and atypical development, multifinality and equifinality, the dynamic processes of resilience, and the integration of multiple levels of analysis into developmental theories. In this paper we assert that person-centered data analytic methods are particularly well-suited to advancing these tenets of developmental psychopathology. We illustrate their utility with a brief novel empirical study focused on underlying patterns of childhood neuroendocrine regulation and prospective links with emerging adult functioning.

Interpersonal Mechanisms Between Child Maltreatment Timing and Young Adult Internalizing and Externalizing Symptomatology.

Objective: Children who experience maltreatment are prone to exhibit interpersonal deficits and lack secure attachment, which can lead to internalizing and externalizing symptomatology. This study investigated timing and chronicity of maltreatment and its impacts on psychopathology outcomes in young adulthood. Two interpersonal mediators were examined: problems with peers and childhood attachment security.

Profiles of diurnal cortisol and DHEA regulation among children: Associations with maltreatment experiences, symptomatology, and positive adaptation.

Person-centered methods represent an important advance in the simultaneous examination of multiple indicators of neuroendocrine functioning and may facilitate a more nuanced understanding of the impact of child maltreatment on hypothalamic-pituitary-adrenal axis dysregulation. The aims of the present study were threefold: (a) identify naturally occurring patterns of diurnal cortisol and dehydroepiandrosterone (DHEA) regulation among a sample of = 1,258 children with and without histories of maltreatment, (b) investigate which neuroendocrine profiles characterize children with exposure to maltreatment, and (c) examine which profiles are related to adaptive outcomes and symptomatology among children. Cortisol and DHEA were sampled three times per day (9 a.

Patterns of childhood maltreatment predict emotion processing and regulation in emerging adulthood.

Childhood maltreatment is a potent interpersonal trauma associated with dysregulation of emotional processes relevant to the development of psychopathology. The current study identified prospective links between patterns of maltreatment exposures and dimensions of emotion regulation in emerging adulthood. Participants included 427 individuals (48% Male; 75.

A Longitudinal Examination of Child Maltreatment Dimensions, Emotion Regulation, and Comorbid Psychopathology.

Childhood maltreatment is a toxic stressor that occurs in the family context and is related to adverse outcomes including elevations in internalizing symptomology and externalizing symptomology. In the present study, we tested the role of threat and deprivation dimensions of child maltreatment in the etiology of comorbid psychopathology in emerging adulthood. Additionally, we investigated emotion regulation and emotion lability/negativity as mechanisms underlying the relationship between child maltreatment dimensions and emerging adult psychopathology.

Parents' Maltreatment Histories, Dimensions of Emotion Regulation, and Connections to Offspring Self-Regulation: A Sex-Specific Transmission Pathway.

Introduction: Parents with childhood maltreatment histories are at risk for emotion regulation (ER) problems, which are associated with reduced self-regulation among their offspring. However, gaps remain in the literature regarding this indirect transmission pathway. First, ER consists of multiple dimensions and it is unclear which dimension is most affected by childhood maltreatment.

Child maltreatment and the development of psychopathology: The role of developmental timing and chronicity.

Background: The effects of child maltreatment (CM) on psychopathology are well-established, yet the complex effects of timing and chronicity of maltreatment exposure on the development of psychopathology are still unclear.

Objective: To elucidate developmental pathways from distinct dimensions of CM (chronicity and timing) to psychopathology during emerging adulthood using data from a longitudinal, multi-method study.

Participants And Setting: Children with and without maltreatment exposure were recruited at wave 1 (ages 10-12) to participate in a research summer camp.

Daytime sleepiness underlies the link between adverse parenting and youth psychopathology among adolescent girls.

Introduction: Adverse parenting is associated with sleep problems in adolescence, including sleep quality, inadequate sleep, and daytime sleepiness. Adolescents who experience sleep problems are at greater risk for developing internalizing and externalizing problems. However, research on the intervening role of sleep in the link between adverse parenting and youth psychopathology remains limited.

Child Abuse and Neglect, Callous-Unemotional Traits, and Substance Use Problems: the Moderating Role of Stress Response Reactivity.

Young adults who experienced child abuse and neglect (CAN) are at significant risk for callous-unemotional traits and substance use problems. Research shows that compromised self-regulation may increase risk for these maladaptive outcomes. In the present cross-sectional study, we examined the moderating role of self-regulation, indexed by heart rate variability reactivity, in the indirect link between CAN and alcohol and other drug use problems via callous-unemotional traits.

Physiological Stress Response Reactivity Mediates the Link Between Emotional Abuse and Youth Internalizing Problems.

Youth who are raised in emotionally abusive families are more likely to have poor mental health outcomes such as depression and anxiety. However, the mechanisms of this association are unclear. The present study utilized a longitudinal sample of low-SES youth (N = 101, M = 10.

Harsh parenting and youth systemic inflammation: Modulation by the autonomic nervous system.

Objective: The present study aimed to test the role of the autonomic nervous system (ANS) in modulating the impact of family stress induced by harsh parenting on youths' inflammation. First, we examined the direct effect of severity of adverse parenting behaviors on two serum biomarkers of systemic inflammation (C-reactive protein and interleukin-6) among youth. Second, we tested the moderating role of ANS reactivity in response to laboratory-induced stress in the association between harsh parenting and inflammation among these youth.

Heart Rate Variability Reactivity Moderates the Indirect Link Between Child Maltreatment and Young Adult Alcohol Use Problems Via Depressive Symptoms.

Background And Objectives: Young adults with childhood maltreatment (CM) histories are particularly vulnerable to depressive symptoms and alcohol use problems. Research suggests that maltreated youth may misuse alcohol in part to alleviate depressive symptoms. However, many youths with depressive symptoms exercise self-control and abstain from heavy alcohol use.

A longitudinal investigation of protective factors for bereaved maltreated youth.

Background: Maltreated youth are at an elevated risk for the development of problem behaviors. Coping with the death of a family member or close friend during adolescence, referred to as bereavement, is a stressful event that could potentiate risk linked to maltreatment. However, developmental research suggests that youth adjustment is a product of multiple risk and protective factors.

Adverse Childhood Experiences and Amygdalar Reduction: High-Resolution Segmentation Reveals Associations With Subnuclei and Psychiatric Outcomes.

The aim of the present study was 2-fold: (1) to utilize improved amygdala segmentation and exploratory factor analysis to characterize the latent volumetric structure among amygdala nuclei and (2) to assess the effect of adverse childhood experiences (ACEs) on amygdalar morphometry and current psychiatric symptoms. To investigate these aims, structural (T1) MRI and self-report data were obtained from 119 emerging adults. Regression analysis showed that higher ACE scores were related to reduced volume of the right, but not the left, amygdalar segments.

Child Maltreatment, Delayed Reward Discounting, and Alcohol and Other Drug Use Problems: The Moderating Role of Heart Rate Variability.

Background: Child maltreatment (CM) is robustly associated with youth risk for addictive behaviors, and recent findings suggest that this may be mediated through impulsive discounting of future rewards. However, research indicates that youth self-regulation (emotional and cognitive), particularly in peer contexts, is critical to consider in the study of decision making. This study aimed to examine the indirect link between CM and alcohol and other drug use problems, through delayed reward discounting (DRD), among a community sample of emerging adults.

Growth patterns of future orientation among maltreated youth: A prospective examination of the emergence of resilience.

During adolescence, a positive outlook toward the future (i.e., future orientation) can protect youth from the risks conferred by childhood adversity.

Alcohol Use and Depressive Symptoms Among a Nationally Representative Sample of Youth Investigated for Maltreatment.

Objective: The relationships between depressive symptoms and alcohol use among maltreated youth have been well documented. However, the direction of these associations remains unclear. Two prevalent but contrasting perspectives on these associations-the self-medication and impaired-functioning hypotheses-have each received extensive support.
