McMains JT, Liu S, Oshri A, Sweet LH. Childhood maltreatment and substance use risk: A moderated mediation model of autonomic reactivity and distress tolerance. CHILD ABUSE & NEGLECT 2024; 154:106940. [PMID: 39024782 PMCID: PMC11316649 DOI: 10.1016/j.chiabu.2024.106940] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Subscribe] [Scholar Register] [Received: 11/02/2023] [Revised: 05/20/2024] [Accepted: 07/02/2024] [Indexed: 07/20/2024]
Abstract
BACKGROUND/AIMS The link between child maltreatment (CM) and substance use (SU) in young adulthood is established. The sympathetic nervous system (SNS) division of the autonomic nervous system may mediate this link. However, less is known on the indirect link between CM and SU via SNS functioning. Due to individual variability in the link between SNS functioning and SU risk, we aimed to examine the moderating role of distress tolerance (DT). METHODS A longitudinal sample of 118 young adults (YAs) from a low socioeconomic status background were assessed twice (between 9 and 12 months apart). CM, DT, and galvanic skin response (GSR) stress reactivity were measured during the initial study visit, while SU was assessed at both timepoints. Stress reactivity was assessed by measuring the GSR reactivity during a stress task. We tested the indirect associations between CM and changes in SU problems via GSR stress reactivity, and the moderation effects of DT on these indirect associations. A mediation model in the structural equation modeling (SEM) framework was then followed by a moderated mediation model to analyze these data. RESULTS YA's stress reactivity mediated the association between CM and alcohol use problems, and this indirect effect was weaker among YAs who had higher levels of DT. This pattern did not emerge with drug use problems. CONCLUSIONS Findings suggest that intervention and prevention efforts for SU outcomes should consider incorporating strategies that increase at-risk individuals' levels of DT. Providing strategies to help individuals stem their stress reactivity may reduce their risk for alcohol use.

J Adolesc 2024; 96:18-30.

Abstract
INTRODUCTION Exposure to childhood maltreatment may undermine the crucial developmental task of identity formation in adolescence, placing them at risk for developing negative affect. The current study investigated whether COVID-19-related stress intensified the indirect link between child maltreatment and adolescents' negative affect through identity confusion. METHOD Using multidimensional assessments of child maltreatment (threat vs. deprivation), the study included a sample of 124 adolescents (Mage = 12.89, SD = 0.79; 52% female) assessed before (January 2018 to March 2020) and during the pandemic (May to October 2020) in Georgia, United States. The majority of the participants were European American (78.8%), followed by African American (11.5%), Hispanic (3.8%), Asian/Pacific Islander (1.0%), and other (4.8%). We used structural equation modeling to test (a) the mediating role of identity confusion in the link between childhood maltreatment and negative affect and (b) whether COVID-19-related stress moderated these indirect effects. Simple slopes and Johnson-Neyman plots were generated to probe regions of significant interaction effects. RESULTS Threat and deprivation predicted an increase in adolescent identity confusion. Additionally, childhood threat and deprivation were indirectly linked to adolescents' negative affect through increased levels of identity confusion. COVID-19-related stress significantly exacerbated the link between identity confusion and negative affect. CONCLUSION Identity confusion is a mechanism underlying the link between child maltreatment and the development of negative affect in adolescence. Our results inform prevention and intervention programs that aim to reduce negative affect among adolescents who experience threatening and depriving rearing environments.

Abstract
Introduction Young adulthood is a transitional period between adolescence and adulthood. Due to the unique pressures of taking on a new social role and associated uncertainties, young adults are at heightened risk for drug and alcohol use. Furthermore, adverse childhood experiences (ACEs) increases the likelihood of using maladaptive coping strategies such as using substances to avoid or soothe negative emotions. The current review aimed to summarize the associations between exposure to ACEs before the age of 18 years and subsequent drug or alcohol use between the ages of 18 and 25 years. Methods The review was performed in accordance with the 2020 Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. The literature search of the Web of Science, PubMed, and PsycINFO databases was conducted in February 2022. Results The initial search yielded 7178 articles, with 777 duplicates. Consequently, 6401 titles were inspected for relevance. After reading the full text, 88 articles were included in the review. Conclusion This review provides clear evidence that exposure to multiple ACEs is a robust risk factor for the use of alcohol, cannabis and other drugs by young adults. Poor self-regulation and maladaptive coping strategies were identified as mechanisms explaining this link; however, further detailed research is needed.

Abstract
Experiences of child abuse and neglect are risk factors for youth suicidal thoughts and behaviors. Accordingly, suicide risk may emerge as a developmental process that is heavily influenced by the rearing environment. We argue that a developmental, theoretical framework is needed to guide future research on child maltreatment and youth (i.e., adolescent and emerging adult) suicide, and to subsequently inform suicide prevention efforts. We propose a developmental model that integrates principles of developmental psychopathology and current theories of suicide to explain the association between child maltreatment and youth suicide risk. This model bears significant implications for future research on child maltreatment and youth suicide risk, and for suicide prevention efforts that target youth with child maltreatment experiences.

Abstract
OBJECTIVE Native American adolescents are disproportionately burdened by suicidality. Here, we examine patterns of reporting of suicide ideation and suicide attempt among Native American youth compared to those from other ethnoracial backgrounds, as this data is important for grounding commonly subscribed to frameworks of suicide risk (e.g., ideation-to-action). METHOD Data are from the Youth Risk Behavior Surveillance Survey (N = 54,243; grades 9-12; 51.0% female) and Minnesota Student Survey (N = 335,151; grades 8, 9, 11; 50.7% female). Comparing Native American youth to peers from other ethnoracial backgrounds, we examined two suicide reporting patterns: 1) odds of reporting suicide attempt among those who reported ideation and 2) odds of reporting suicide ideation among those who reported an attempt. RESULTS Across both samples, when reporting suicide ideation, youth from other ethnoracial backgrounds were 20-55% less likely than Native American youth to also report attempt. While few consistent differences were observed between Native American youth and those from other racial minority backgrounds in patterns of co-reporting suicide ideation and attempt across samples, White youth were between 37% and 63% less likely than Native American youth to report a suicide attempt without also reporting ideation. CONCLUSIONS The increased odds of engaging in a suicide attempt with or without reporting ideation question the generalizability of widely held frameworks of suicide risk to Native American youth and have important implications for suicide risk monitoring. Future research is needed to illuminate how these behaviors unfold over time and the potential mechanisms of risk for engaging in suicide attempts in this disproportionately burdened group.Abbreviations: YRBSS: Youth Risk Behavior Surveillance Survey; MSS: Minnesota Student Survey.

Abstract
Following a stressful life event, there is considerable variation in how individuals respond and adapt. Multiple models of risk and resilience show that adverse childhood experiences may be associated with an individual's response to stress later in life. While there is considerable support that early adversity can sensitize the stress response system and lead to adverse outcomes later in life, there is mounting evidence that in adolescence and young adulthood, certain biological predispositions to stress may be associated with resilience in the context of subsequent stressors. In this study, we evaluated how individual differences in vagally mediated heart rate variability moderated the relationship between childhood maltreatment and grief among a sample of individuals experiencing a stressful life event (i.e., spousal bereavement) over time. Data were collected at approximately 3, 4.5, and 6.5 months after the death of a spouse (n = 130). Heart rate variability moderated the relationship between childhood maltreatment and grief symptoms over time (b = -0.03, p < .001), such that among individuals with more severe experiences of childhood maltreatment, those with higher heart rate variability had a faster recovery from grief than those with low heart rate variability. This research highlights an overall pattern of resilience among older adult's following spousal bereavement, as well as the relationships between childhood maltreatment, heart rate variability, and differential responses to grief following the loss of a spouse.

Abstract
In developmental science, resilience refers to children and youths’ ability to recover and pursue positive development in the face of stress related to adversity. Extant research has documented protective factors and ecological contexts that mitigate the impact of adversity and thereby promote resilience. One intriguing aspect of resilience is that individuals also develop strength in response to early adversity. However, very little theoretical guidance exists on the developmental mechanisms and contexts through which early adversity may lead to strengthening effects that confer the process of resilience. The strengthening mechanism in the context of specific circumscribed environmental stress is a process known in the field of toxicology as hormesis. It is proposed here that the study of resilience in developmental and psychological sciences can benefit from shifting more attention to the hormesis model. The hormesis model is reviewed and discussed as a promising perspective on mechanisms, developmental timing, and context through which adversity strengthens or impedes resilience.

Abstract
BACKGROUND AND AIMS Nonsuicidal self-injury (NSSI) is highly prevalent in adolescents and is associated with various mental health problems. Repetitive NSSI (R-NSSI), as an extreme manifestation of NSSI, is a growing concern and has been proposed as a behavioral addiction. However, little is known about the potential addictive mechanisms of NSSI. This study aimed to examine the mediating effect of emotion dysregulation and the moderating effect of impulsivity using the Interaction of Person-Affect-Cognition-Execution (I-PACE) model in adolescents who repeatedly engage in NSSI. METHODS A total of 3,915 adolescents (mean age = 13.21 years, SD = 0.87, 57.6% male) were recruited from three middle schools. Relevant questionnaires were used to evaluate childhood maltreatment, emotion dysregulation, impulsivity, and NSSI. Mediation and moderated mediation analyses were conducted separately for adolescents with occasional NSSI (O-NSSI) and R-NSSI to assess the relationship between childhood maltreatment, emotion dysregulation, impulsivity, and NSSI frequency. RESULTS Our study found that childhood maltreatment was directly related to NSSI and indirectly related to NSSI through emotion dysregulation in both the R-NSSI and O-NSSI groups. Furthermore, impulsivity played a moderating role in the relationship between emotion dysregulation and NSSI in the R-NSSI group but not in the O-NSSI group. DISCUSSION AND CONCLUSIONS The findings suggest that a high level of impulsivity and a high level of emotion dysregulation may be important risk addictive factors of NSSI through childhood maltreatment. Strengthening the emotion regulation skills and inhibitory control of adolescents with NSSI would be helpful to reduce their self-injury behaviors and maintain their mental health. This finding also supports the validity of the I-PACE model for evaluating R-NSSI.

BMC Public Health 2022; 22:1576. [PMID: 35986265 PMCID: PMC9388997 DOI: 10.1186/s12889-022-13969-1] [Citation(s) in RCA: 7] [Impact Index Per Article: 3.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/06/2022] [Accepted: 08/02/2022] [Indexed: 11/10/2022] Open
Abstract
Abstract
Background
Delay Discounting is the extent to which one prioritizes smaller immediate rewards over larger, delayed rewards. The ability to prospect into the future is associated with better health decision-making, which suggests that delay discounting is an important intervention target for the prevention and treatment of chronic disease. Delay discounting decreases throughout development and stressful experiences, particularly those that accompany poverty, may influence this developmental trajectory. The current study leveraged the COVID-19 pandemic and resulting economic downturn as a natural experiment to understand how changes in food insecurity and psychological stress may associated with changes in delay discounting among parents, adolescents, and children.
Methods
A stratified cohort of families (N = 76 dyads), established prior to the initial pandemic lockdowns, were asked to complete a follow-up survey in the summer of 2020, during reopening. Thirty-seven (49%) families had an older adolescent (aged 15 – 18 years) in the study and 39 (51%) had an elementary aged child (aged 7 – 12 years) in the follow-up study. Both data collection points included measurements of economic position, psychological stress, food security status, and delay discounting.
Results
The results showed that pandemic food insecurity was associated with greater stress among parents (β = 2.22, t(65.48) = 2.81, p = 0.007). Parents, Adolescents, and children significantly differed in their response to psychological stress during the pandemic (β = -0.03, t(102.45) = -2.58, p = 0.011), which was driven by a trend for children to show greater delay discounting associated with an increase in psychological stress during the pandemic (β = -0.01, p = 0.071), while adolescents and parents showed no change.
Conclusions
These findings add to the evidence that food insecurity is uniquely stressful among parents with no effects on delay discounting. Despite this, we found no evidence that food insecurity was stressful for child or adolescents. A trend in our data suggested that childhood, as compared with adolescence, may be an important developmental period for the association between stress and delay discounting. Future research should continue the longitudinal investigation of childhood stress and the developmental trajectory of delay discounting to ascertain how these effects may persist in adulthood.

Abstract
BACKGROUND Childhood adversity (CA) is associated with increased risk of psychopathology, and reward processing (RP) may be one of the underlying mechanisms. However, evidence on impaired RP in childhood adversity is theoretically and methodologically heterogeneous. OBJECTIVE To provide a quantitative overview of studies on the relation between childhood adversity and RP assessed at the behavioral and subjective levels, and identify differences between studies that influence the effect size. PARTICIPANTS AND SETTING Twenty-seven studies (overall N = 6801) were included. METHODS Peer-reviewed publications describing empirical studies on the relation between CA and behavioral and self-report measures of RP in humans were identified through systematic searches in six bibliographic databases. Effect sizes (r) were pooled using random-effects models. The potential moderator role of RP dimension, type of RP assessment, type of childhood adversity assessment, and age were examined. RESULTS Results indicated a small, but consistent association between CA and impaired RP (r = 0.12; 95% CI: 0.07, 0.16), with medium heterogeneity (I2 = 62.43). The effect size was significantly larger (i.e., medium-sized) in studies that focused on reward learning rather than reward valuation and reward responsiveness; used cognitive tasks rather than self-report assessments of RP; and relied on official records rather than subjective reports of CA. There was evidence of publication bias, but overall effect size remained significant after imputation. CONCLUSIONS These results suggest that multidimensional RP impairments (e.g., deficits in reward learning, biased reward valuation) are a consistent marker of CA, and may represent mechanisms underlying the increased risk of psychopathology.

Abstract
BACKGROUND Food insecurity, obesity, and psychological stress are interrelated constructs which are thought to be connected through increased energy intake, but the underlying mechanisms for these relationships remain unclear. The current study used experimental methods to investigate how financial losses may influence acute stress in the context of food insecurity for both parents and offspring. This study also sought to examine the effect of acute stress related to financial losses on the reinforcing value of food (RRVfood) and delay discounting (DD). METHODS One hundred and six families stratified by both offspring age (53 children aged 7-10, 53 adolescents aged 15-17) and household financial resources, visited our laboratory for three separate appointments. Each appointment included the experimental manipulation of financial gains and losses, saliva samples for cortisol assay, continuous heart rate monitoring, self-rated tension, and computer-based DD and RRVfood tasks. Participants also completed surveys to report perceived life stress level and food insecurity status. RESULTS Among all participants, financial losses were related to decreased heart rates and increased self-rated tension. Among parents reporting food insecurity, acute financial losses resulted in an increase in cortisol levels. Changes in cortisol, heart rate, and tension were not related to RRVfood or DD. CONCLUSION Food insecure parents are sensitive to financial losses and respond with an increase in cortisol. However, we found no evidence for a relationship between cortisol and RRVfood or DD. This sensitivity to financial losses did not extend to children or adolescents.

Abstract
Early life stress (ELS) is a well-established risk factor for many psychiatric and medical disorders, including substance use disorders (SUDs). The relationship between ELS and SUDs is complex and there are likely multiple pathways from ELS to adverse substance use outcomes. The association between ELS and substance use emerges in adolescence. Adolescence is a critical period in development during which substance exposure markedly increases risk for SUDs. Therefore, this review focuses on the literature supporting the hypothesis that ELS increases risk for the development of SUDs through its influence on adolescent substance use. We discuss studies substantiating the role of ELS in adolescent substance use and explore how internalizing and externalizing psychopathology may be antecedents of substance use in adolescence. We examine clinical work suggesting ELS sculpts the Hypothalamic-Pituitary-Adrenal (HPA) Axis and developing brain-particularly subcortical brain regions that underlie stress response, mesocorticolimbic brain systems associated with reward sensitivity, and prefrontal regions that underlie executive control-in a way that increases risk for adolescent substance use and SUDs. We further explore how substance use during adolescence alters structure and function of these same systems, and how brain changes following ELS and adolescent substance use may independently, additively, or interactively contribute to risk for addiction. We conclude by discussing how the current literature can inform interventions aimed at reducing risk for SUDs in individuals with a history of ELS.

Abstract
RATIONALE Exposure to adverse life experiences (ACEs) is robustly associated with problematic alcohol and other drug use. In addition, both ACEs and substance use have been independently associated with impulsivity. OBJECTIVE To examine whether impulsivity is implicated in the link between ACE and adult substance use in two samples. METHODS The primary sample was a cohort of community adults (N = 1431) who completed a one-time in-person assessment. A second sample was crowdsourced using Amazon Mechanical Turk (N = 3021). All participants were assessed for ACEs using the Adverse Childhood Experience Questionnaire and for current alcohol and other drug use. Given its multidimensional nature, impulsivity was assessed using the UPPS-P measure of impulsive personality traits, Go/NoGo (GNG) task (in-person community adult sample only), and delay discounting (Monetary Choice Questionnaire [MCQ] in the community adults and Effective Delay-50 [ED50] in the crowdsourced sample. Structural equation modeling was used to examine the hypothesized indirect effects for the measures of impulsivity between ACEs and substance use. RESULTS In the community adults, significant indirect effects were observed from ACEs to substance use via UPPS-Negative Urgency (β = 0.07, SE = 0.02, 95% CI [0.04, 0.10]), and the MCQ (β = 0.02 SE = .01, 95% CI [0.01, 0.03]). In the crowdsourced sample, significant indirect effects were observed from ACEs to substance use via UPPS-Negative Urgency (β = 0.05, SE = .01, 95% CI [0.04, 0.07]), UPPS-Premeditation (β = 0.04, SE = .01, 95% CI [0.02, 0.05), and the ED50 (β = 0.02, SE = .01; 95% CI [0.01, 0.03]). CONCLUSION These findings provide consistent evidence that decrements in regulation of negative emotions and overvaluation of immediate rewards indirectly link ACE and substance use. These robust cross-sectional findings support the need for elucidating the underlying neural substrates implicated and for longitudinal evaluations.

Abstract
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. We utilized a sample of mostly female undergraduate students (N = 130, 81% Female; M age = 20.72). We hypothesized that (a) CAN and alcohol or other drug use problems would be associated indirectly via elevations in callous-unemotional traits, and (b) that this indirect association would be exacerbated by elevated heart rate variability reactivity. Results indicated that increased callous-unemotional traits underlain in the link between CAN and alcohol or other drug use problems. Further, this indirect link was exacerbated among youth with elevated heart rate variability reactivity. These findings have significant implications for prevention by demonstrating that physiological self-regulation is important to target in substance use prevention among collegiate samples.

Abstract
Recent focus on the consequences of early life adversity (ELA) in neurobiological research led to a variety of findings suggesting alterations in several physiological systems, such as the cardiovascular system. In this systematic review and meta-analysis, we focused on the relationship between early life maltreatment (ELM), one form of ELA, and resting vagal activity indexed by resting-state heart rate variability (HRV). A systematic search of the literature yielded 1'264 hits, of which 32 studies reporting data for group comparisons or correlations were included. By quantitative synthesis of existing studies using random-effect models, we found no evidence for a relationship between ELM exposure and resting vagal activity in principal. Conducting meta-regression analyses, however, we found the relationship between ELM and resting vagal activity to significantly vary as a function of both age and the presence of psychopathology. In light of the current multitude of vastly unclear pathways linking ELM to the onset of disease, we emphasize the need for further research and outline several aspects to consider in future studies.

Abstract
Harsh parenting is a significant predictor of youth aggression and delinquency. However, not every child exposed to adverse parenting develops such problem behaviors. Recent developmental evolutionary models suggest that variability in stress response reactivity to parenting, reflected by autonomic nervous system (ANS) functioning, may affect the impact of adverse parenting on youth behavioral adjustment. The aim of the present study was to investigate whether the parasympathetic and sympathetic branches of the ANS moderate the association between parenting and aggressive and delinquent behaviors. The study sample included low-income, ethnically diverse preadolescents (M = 10.28 years old; N = 101) and their caregivers. Direct effects were found from basal RSA to delinquent behaviors. In addition, harsh parenting predicted increased youths' aggressive and delinquent behaviors in the context of high RSA withdrawal and increased youths' delinquent behaviors in the context of shortened basal PEP. Implications for prevention and intervention are discussed.

Abstract
BACKGROUND Young adults with a history of child maltreatment (CM) are often vulnerable to alcohol-related problems. Drinking motives have been widely studied to explain alcohol-related problems in young adulthood. OBJECTIVES The aims of the current study were to examine the link between CM and alcohol-related problems and to test whether CM is indirectly related to alcohol-related problems via different types of drinking motives. PARTICIPANTS AND SETTING Two hundred eight participants were recruited in a mid-Atlantic urban area (M age = 19.7, 78.4 % female) via advertisements placed throughout the community. METHODS Participants completed self-report measures of CM (Childhood Trauma Questionnaire), types of drinking motives (the Drinking Motives Questionnaire Revised Short Form), and alcohol-related problems (Rutgers Alcohol Problem Index). Structural equation modeling (SEM) was used to test whether CM was associated with alcohol use, both directly and indirectly, through drinking motives. RESULTS We found that both coping (β = 0.53,p < 0.001) and enhancement drinking motives (β = 0.15, p = 0.031) were associated with alcohol-related problems. Additionally, CM was related to alcohol-related problems indirectly via coping motive (β = 0.11, p = 0.028). CONCLUSION Young adults with a history of CM may use alcohol to cope with trauma-related negative emotionality. Targeting emotional distress in CM-exposed individuals may be helpful in preventing and treating alcohol-related problems in this vulnerable population.

Abstract
This narrative review examines associations of delay discounting, response inhibition, sensation-seeking, and urgency with adolescent problem substance use. Each of these processes is linked to adult substance use disorders, is associated with conditions linked to increased risk for adolescent problem substance use, and predicts problem substance use. Notably, all processes are linked to early life adversity (ELA) exposure and most appear to help explain links between ELA exposure and problem substance use. These findings are consistent with a growing body of literature indicating ELA interferes with the development of neural circuits crucial to cognitive functioning and emotion regulation. Further, developmental trajectories of these processes generally align with maturational imbalance hypotheses of adolescent risk. Ongoing and pending large longitudinal studies may be essential for better understanding how ELA and other influences shapes these processes and the role of these processes in risk for problem substance use in adolescence and beyond. Finally it is possible that risk-related processes may be useful metrics in the context of implementing and evaluating strategies to prevent problem substance use in adolescence.

Abstract
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. The present study aimed to examine the influence of heart rate variability reactivity (HRV-R), a psychophysiological biomarker of self-regulation, in the indirect link between CM and alcohol-use problems via depressive symptoms among low socioeconomic-status rural young adults. METHODS Two waves of data were collected from a community sample of 225 low socioeconomic-status nonmetropolitan young adults (Mage = 21.56, 52.9% female). HRV data were obtained with an electrocardiogram during a social stress task. CM was assessed through the Childhood Trauma Questionnaire. Alcohol use problems were measured using the Alcohol Use Disorders Identification Test. RESULTS The indirect effect of CM on alcohol use problems via elevated depressive symptoms was positive and significant (α × β = .159, P < .001). Self-regulation, indicated by high HRV-R (ie, vagal withdrawal), was found to significantly buffer the link between depressive symptoms and alcohol use problems (β = .193, P = .022). DISCUSSION AND CONCLUSIONS Adequate self-regulation capacities can protect maltreated youths from self-medicating alcohol use problems. SCIENTIFIC SIGNIFICANCE This study will advance researchers' understanding of the development of alcohol use problems through unwrapping the risk and protective mechanisms underlying the association between young adults' early life stress and alcohol use behaviors.

Abstract
Although child maltreatment is a major public health concern, which adversely affects psychological and physical development, we know relatively little concerning psychophysiological and personality factors that may modify risk in children exposed to maltreatment. Using a three-wave, short-term prospective design, we examined the influence of individual differences in two disparate psychophysiological measures of risk (i.e., resting frontal brain electrical activity and respiratory sinus arrhythmia) on the trajectories of extraversion and neuroticism in a sample of female adolescents (N = 55; M age = 14.02 years) exposed to child maltreatment. Adolescents exposed to child maltreatment with relatively higher left frontal absolute alpha power (i.e., lower brain activity) at rest exhibited increasing trajectories of extraversion, and adolescents exposed to child maltreatment with relatively lower respiratory sinus arrhythmia at rest displayed increasing trajectories of neuroticism over 1 year. Individual differences in psychophysiological measures indexing resting central and peripheral nervous system activity may therefore differentially influence personality characteristics in adolescent females exposed to child maltreatment.

Abstract
Child maltreatment is associated with a variety of risk behaviors in young adulthood; however, the underlying cognitive and neural mechanisms of this relation are not well understood. The primary aim of the present study was to examine the direct and indirect effects between maltreatment in childhood and downstream impulsivity via neural activity during a cognitive task. In a sample of emerging adult women from the rural southeastern United States, childhood abuse and neglect were assessed using the childhood trauma questionnaire. Outcome measures of neural activity during a functional magnetic resonance imaging N-back verbal working memory (WM) task and trait impulsivity on the Impulsive Behavior Scale were assessed approximately 1 year later. Results indicate that adults with higher levels of reported childhood maltreatment demonstrate worse behavioral performance and lower neural response during a difficult verbal WM task. Furthermore, neural activity significantly mediated the relation between abuse and neglect in childhood and trait impulsivity. These new findings demonstrate an association between neurocognitive functioning and reported childhood abuse and neglect, and indicate that such changes may underlie the relation between maltreatment and trait-level impulsivity.

Abstract
Prolonged exposure to socioeconomic hardship (SH) is associated with greater delayed reward discounting (DRD), a form of impulsive decision-making that reflects a reduced capacity to delay gratification and a significant correlate of diverse risk behaviors, but the neurobehavioral mechanisms linking SH and DRD are unknown. An emerging hypothesis suggests that cognitive and affective stress associated with poverty may tax neurocognitive functions, such as working memory (WM), and lead to impulsive DRD. Furthermore, research suggests that emotional reactivity (ER) is an important dispositional factor to consider in the link between executive functions and DRD. Thus, we longitudinally examined the indirect effect of SH on impulsive DRD via a network of brain regions associated with WM function in a sample of young adults, and whether that link was moderated by ER. Participants were 119 rural African Americans (aged 19–24 years) assessed behaviorally on four occasions, with fMRI at the last time point. Results showed that, among emerging adults with higher ER, SH severity was predictive of increased DRD via reduced response in brain regions activated during an n-back WM task. These findings reveal both the cognitive and affective mechanisms that underlie the relationship between SH and DRD.

Abstract
Delayed reward discounting (DRD) is a behavioral economic measure of impulsivity, reflecting how rapidly a reward loses value based on its temporal distance. In humans, more impulsive DRD is associated with susceptibility to a number of psychiatric diseases (e.g., addiction, ADHD), health outcomes (e.g., obesity), and lifetime outcomes (e.g., educational attainment). Although the determinants of DRD are both genetic and environmental, this review focuses on its genetic basis. Both rodent studies using inbred strains and human twin studies indicate that DRD is moderately heritable, a conclusion that was further supported by a recent human genome-wide association study (GWAS) that used single nucleotide polymorphisms (SNP) to estimate heritability. The GWAS of DRD also identified genetic correlations with psychiatric diagnoses, health outcomes, and measures of cognitive performance. Future research priorities include rodent studies probing putative genetic mechanisms of DRD and human GWASs using larger samples and non-European cohorts. Continuing to characterize genomic influences on DRD has the potential to yield important biological insights with implications for a variety of medically and socially important outcomes.
