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. Results indicate that a childhood neuroendocrine profile marked by high diurnal cortisol paired with low diurnal DHEA was uniquely associated with more adaptive functioning in emerging adulthood. We discuss these findings, and person-centered methods more broadly, within the future of developmental psychopathology.

The relative effects of parental alcohol use disorder and maltreatment on offspring alcohol use: Unique pathways of risk.

Childhood adversity represents a robust risk factor for the development of harmful substance use. Although a range of empirical studies have examined the consequences of multiple forms of adversity (i.e., childhood maltreatment, parental alcohol use disorder [AUD]), there is a dearth of information on the relative effects of each form of adversity when considered simultaneously. The current study utilizes structural equation modeling to investigate three unique and amplifying pathways from parental AUD and maltreatment exposure to offspring alcohol use as emerging adults: (1) childhood externalizing symptomatology, (2) internalizing symptomatology, and (3) affiliation with substance-using peers and siblings. Participants (N = 422) were drawn from a longitudinal follow-up study of emerging adults who participated in a research summer camp program as children. Wave 1 of the study included 674 school-aged children with and without maltreatment histories. Results indicated that chronic maltreatment, over and above the effect of parent AUD, was uniquely associated with greater childhood conduct problems and depressive symptomatology. Mother alcohol dependence was uniquely associated with greater affiliation with substance-using peers and siblings, which in turn predicted greater alcohol use as emerging adults. Results support peer and sibling affiliation as a key mechanism in the intergenerational transmission of substance use between mothers and offspring.

Developmental pathways from child maltreatment to adolescent pregnancy: A multiple mediational model.

Adolescent pregnancy (AP) is a significant public health issue. Child maltreatment (CM) represents an established risk factor, yet little is known about the explanatory mechanisms linking the phenomena. Informed by developmental theory, this study prospectively tested seven multi-level, indirect pathways that could plausibly explain the relationship between CM and AP: (1) substance use (polysubstance use and frequency); (2) sexual risk behavior; (3) depressive symptoms; (4) posttraumatic stress disorder symptoms; (5) cognitive dysregulation; (6) pregnancy desire and difficulty expectancies; and (7) age at menarche. Data came from a prospective, longitudinal cohort study of 469 ethnically diverse, nulliparous adolescent females, designed to examine the impact of substantiated CM on reproductive outcomes such as pregnancy and childbirth (265 maltreated and 204 demographically matched comparison adolescents). A multiple-mediator structural equation model was conducted to simultaneously test multiple indirect effects while accounting for confounding variables. Maltreatment had an indirect effect on pregnancy via substance use and higher pregnancy desire/lower perceived difficulty. Findings represent a step towards elucidating pathways linking CM with AP. Recommendations are offered to prevent pregnancy by addressing the pregnancy-specific mechanisms that are part of the maltreatment sequelae.

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 N = 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.m., 12 p.m., and 4 p.m.) across 5 and 2 days, respectively. Four profiles of cortisol and DHEA regulation were identified. Among females, a pattern marked by high cortisol and low DHEA was associated with more pervasive maltreatment experiences. Furthermore, we found evidence of adaptive interpersonal resilience such that children with maltreatment exposure who evidenced this pattern of high cortisol and low DHEA were viewed as more likeable than maltreated children with other neuroendocrine patterns. Finally, results pointed to higher levels of internalizing symptoms among children who displayed a profile marked by average cortisol and high DHEA.

A person-centered data analytic approach to dopaminergic polygenic moderation of child maltreatment exposure.

The present study illustrates the utility of latent class analysis, a person-centered data analytic approach, as an innovative method for identifying naturally occurring patterns of polygenic risk, specifically within the dopaminergic system. Moreover, this study tests whether latent classes of polygenic variation moderate the effect of child maltreatment exposure on internalizing symptoms among African ancestry youth. African ancestry youth were selected for this study because youth of color are overrepresented in the child welfare system and because African ancestry individuals are significantly underrepresented in genomics research. Results identified three latent classes of dopaminergic gene variation. Class 1 was marked predominately by homozygous minor alleles, Class 2 was characterized by homozygous major and heterozygous presentations, and Class 3 was marked by heterozygous alleles on the DAT-1 single-nucleotide polymorphisms (SNPs) and a combination of homozygous major and minor alleles on the other SNPs. Results indicated that a greater number of maltreatment subtypes experienced were associated with higher internalizing symptoms only for children with the latent polygenic Class 2 pattern. This latent class was distinctly characterized by more homozygous major or heterozygous allelic presentations along all three DAT-1 SNPs. This significant latent polygenic class by environment interaction was replicated in an independent replication sample. Together, findings suggest that African ancestry children with a pattern of dopaminergic variation characterized by this specific combination of polygenic variation are more vulnerable to developing internalizing symptoms following maltreatment exposure, relative to their peers with other dopamine-related polygenic patterns.

Childhood attachment security mediates the effect of childhood maltreatment chronicity on emotion regulation patterns in emerging adulthood.

This study uses a 2-wave, longitudinal design to evaluate mother-child attachment security (child-reported) and emotion regulation capacities (wave 1, age 10-12) as mediators linking childhood maltreatment chronicity and emotion regulation (ER) patterns in emerging adulthood (wave 2; N = 399; 48.1% male; 77.2% Black/African-American, 11.3% White, 7.8% Hispanic, 3.8% other race). Children from families eligible for public assistance with and without maltreatment exposure participated in a summer research camp (wave 1) and were recontacted in emerging adulthood (wave 2). SEM results showed that greater maltreatment chronicity predicted lower childhood attachment security, which in turn predicted membership in ER profiles marked by emotion dysregulation and limited access to ER strategies. Greater attachment security predicted membership in adaptive ER profiles in emerging adulthood. Results suggest that insecure attachment is one process by which childhood maltreatment disrupts adaptive ER across development, whereas greater attachment security in childhood can promote multiple forms of adaptive emotion regulation.

Teen childbearing and offspring internalizing symptoms: The mediating role of child maltreatment.

Teenage childbearing (age 15-19 years) represents a significant public health issue that can generate considerable deleterious, multigenerational consequences for teen-childbearing mothers and their offspring. However, few studies have examined the potential mediating mechanisms that may explain if and how teen childbearing is associated with the development of offspring psychopathology. The current study used a developmental model to test the mediating role of chronic child maltreatment in the relationship between teen childbearing and offspring internalizing symptoms in childhood and emerging adulthood. The study participants were 384 individuals from socioeconomically disadvantaged, ethnically diverse backgrounds, assessed across two longitudinal waves of data (i.e., ages 10-12 and 18-20). The sample included maltreated and nonmaltreated children, all of whom were comparable in terms of family income. Structural equation modeling was conducted to test direct and indirect pathways from teen childbearing to offspring psychopathology. A multigenerational developmental cascade was found such that individuals born to mothers who began their childbearing in adolescence were more likely to experience chronic maltreatment during childhood, which in turn predicted greater internalizing symptoms throughout childhood and emerging adulthood. Using a developmental psychopathology framework, the results are discussed with regard to implications for prevention and early intervention.

Characterizing competence among a high-risk sample of emerging adults: Prospective predictions and biological considerations.

Few conditions epitomize severe and chronic stress to a greater extent than child maltreatment, which can derail development across multiple domains of functioning and throughout the life course. Furthermore, child maltreatment tends to co-occur with other adversities, such as poverty. Many individuals grow up under the stressful conditions of these adversities and exhibit developmental competence. The current study prospectively charted the developmental progression of economically disadvantaged maltreated and nonmaltreated children from childhood to emerging adulthood, and examined patterns of competence across multiple developmental domains of functioning central to the period of emerging adulthood. The study investigated childhood precursors to these patterns of adaptation and maladaptation, as well as the physiological cost of these patterns of adaptation (i.e., C-reactive protein; CRP). Latent class analysis revealed four distinct classes of functioning: multifaceted competence across domains (Multifaceted Competence); (multifaceted maladaptation across domains (Multi-Problem); (c) and two classes with mixed patterns of competence and maladaptation (Externalizing Problems and Work/School Impairment). Maltreated individuals were less likely than nonmaltreated individuals to demonstrate patterns of multifaceted competence and more likely to demonstrate aggregate maladaptation across domains. Additionally, Black men who demonstrated a pattern of multifaceted psychosocial competence also evidenced higher levels of low-grade inflammation (indexed by CRP), suggesting physiological distress was associated with adaptation in the context of stress among these individuals. Findings demonstrate the heterogenous patterns of functioning and diverse developmental outcomes that follow early adversity.

Developmental cascades from child maltreatment to negative friend and romantic interactions in emerging adulthood.

Maltreatment during childhood is associated with difficult interpersonal relationships throughout the life course. The aim of the current study was to investigate differential pathways from child maltreatment to emerging adult relationship dysfunction. Specifically, we prospectively tested whether child maltreatment initiates a developmental cascade resulting in coercive negative romantic and friend interactions in emerging adulthood via childhood antisocial tendencies and via childhood relational aggression. Utilizing a longitudinal sample of emerging adult participants (N = 392; mean age = 20 years old) who took part in a summer research camp program as children (mean age = 11 years old), results supported pathways via both childhood antisocial behavior and childhood relational aggression. We found specificity within these pathways such that childhood antisocial behavior was a mediator of child maltreatment effects on emerging adult negative romantic interactions, whereas childhood relational aggression was a mediator of child maltreatment effects on emerging adult negative friend interactions. Taken together, results indicate that children exposed to maltreatment face significant interpersonal challenges in emerging adulthood, within both the friend and the romantic domains, and point to distinct childhood pathways to these negative interactions. Our findings are consistent with Dishion's (2016) theoretical framework for understanding the development of coercion in relationships and highlight the criticality of early intervention with maltreating families.

Profiles of socioemotional functioning in children with and without CPS-subtantiated maltreatment: Associations with child maltreatment and dating violence.

OBJECTIVE: Person-centered approaches are essential for characterizing heterogeneity in child development as it relates to child maltreatment (CM) and dating violence. The present study had two aims: 1) identify person-centered patterns of childhood socioemotional functioning, 2) examine whether patterns of child socioemotional functioning mediate the association between CM and dating violence. PARTICIPANTS AND SETTING: Wave 1 comprised N = 680 children ages 10-12 years with and without experiences of CPS-substantiated CM facing socio-economic challenge. Wave 2 included N = 407 emerging adults ages 18-24 years old. METHODS: Children participated in a summer camp research program at Wave 1 and a follow up interview at Wave 2. Participant CM history and socioemotional functioning was assessed at Wave 1. Exposure to dating violence was assessed at Wave 2. A latent profile analysis identified patterns of socioemotional functioning. Then regression analyses examined associations of socioemotional functioning with CM and dating violence. RESULTS: Three profiles of child socioemotional functioning were identified (well-regulated/low distress, high externalizing/high aggression, high internalizing). CM was significantly associated with membership in the high externalizing/high aggression class. Patterns of child socioemotional functioning did not mediate the association between CM and dating violence, although number of subtypes of CM had a significant positive direct effect on dating violence. CONCLUSIONS: Results underscore the multidimensional nature of socioemotional functioning and the predictive power of number of subtypes of CM on dating violence. Results can be harnessed by clinicians and policy makers to identify those at risk and interrupt cycles of violence.

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. METHOD: Children with and without maltreatment exposure were recruited to take part in a 1-week research summer camp (N = 697; mean [SD] age = 11.29 [0.97] years; 71.3% Black or African American; 50.5% male). Participants were recontacted in young adulthood to complete a second wave of assessments (n = 427; mean [SD] age = 19.67 [1.16] years; 78.0% Black or African American; 48.9% male). Structural equation modeling was used to estimate indirect effects from child maltreatment timing to young adult internalizing and externalizing symptomatology via childhood attachment security and peer problems. RESULTS: Findings highlighted the detrimental impact of chronic maltreatment, which was associated with higher levels of peer problems (ß = .24, p < .001) and less secure attachment (ß = -.13, p < .01) in childhood. Also, lower attachment quality in childhood mediated the association between chronic maltreatment and self-reported internalizing (a × b = 0.02, p < .05) and externalizing symptomatology (a × b = 0.02, p < .05). Additionally, childhood peer problems mediated the association between chronic maltreatment and caregiver-reported internalizing problems (a × b = 0.04, p < .05). CONCLUSION: Chronic maltreatment is particularly harmful for interpersonal outcomes of children. Mediation findings differed by who reported on psychopathology, showing the importance of considering multireporter measures of psychopathology. PLAIN LANGUAGE SUMMARY: Child maltreatment is an interpersonal stressor that may impact developmental outcomes throughout a youth's life. In this study of 697 children who participated in a 1-week research summer camp and were contacted in young adulthood, the authors found that chronic maltreatment significantly increased the risk of difficulties in forming secure attachments as well as having problems with peers during childhood. In turn, these challenges were linked to emotional and behavioral symptomology in young adulthood. These findings emphasize the need to support children facing chronic maltreatment to improve their long-term mental health.

A process model of parental executive functioning as a spillover mechanism linking interparental conflict and parenting difficulties across parenting domains.

There is a well-documented interdependency between destructive interparental conflict (IPC) and parenting difficulties (i.e., spillover effect), yet little is known about the mechanisms that "carry" spillover between IPC and parenting. Guided by a cascade model framework, the current study used a longitudinal, multimethod, multi-informant design to examine a process model of spillover that tested whether parental executive functioning (working memory, cognitive flexibility, inhibitory control) served as a mediator of the prospective associations between IPC and subsequent changes in parenting over a 2-year period. Mothers and fathers were separated into differentiated models and multiple domains of parenting were examined (i.e., authoritarian discipline and scaffolding behavior). Participants included 231 families (both mothers and fathers of preschoolers). Race was reported as White (62%), Black (21%), Mixed (8%), Asian (3%), or Other (6%) and 14% considered their ethnicity to be Hispanic/Latino. Median household income was $65,000. Results indicated that for fathers, IPC indirectly predicted domain-general parenting difficulties (increased authoritarian parenting and decreased scaffolding) via deficits in paternal cognitive flexibility (but not inhibitory control or working memory). In mothers, IPC directly predicted domain-specific parenting difficulties (decreased scaffolding only) that did not operate via maternal executive functions. Notably, these effects occurred over and above the influence of parental socioeconomic status. This study constitutes a first step toward documenting parental executive functioning as a mechanism underlying the spillover of IPC to the parent-child relationship. Family interventions intended to interrupt IPC spillover should emphasize father involvement and consider targeting parental executive functions as change mechanisms.

Patterns of childhood maltreatment and maternal substance use disorder on the development of emerging adult offspring substance use.

Exposure to child maltreatment and maternal substance use disorder represent two highly consequential and co-occurring experiences of family-level adversity for the development of concerning substance use behaviors among offspring. The present study uses latent class analysis to identify how characteristics of childhood maltreatment and maternal substance use disorder naturally cluster. Further, this study investigates how distinct patterns of maltreatment and maternal substance use differentially predict emerging adult substance use in offspring. Participants (N = 405) were drawn from a longitudinal follow-up study of emerging adults who participated in a research summer camp program as children. Wave 1 of the study included 674 school-aged children with and without maltreatment histories, all of whom experienced low socioeconomic status. Patterns of child maltreatment experiences, based on coded Child Protective Services record data, and maternal substance use behaviors, per a diagnostic interview, were used to predict Wave 2 (emerging adulthood) substance use. Results indicated that children who were exposed to a pattern of multitype maltreatment and multitype maternal substance dependence, relative to those exposed to multitype maltreatment alone, reported greater alcohol dependence symptoms during emerging adulthood. Additionally, these same individuals reported greater past-year hard liquor consumption relative to those who experienced chronic, multitype maltreatment and maternal alcohol dependence. These findings highlight how a pattern of maternal polysubstance use and multitype maltreatment is particularly consequential for the intergenerational transmission of substance use behaviors.

Patterns of Mother, Father, and Peer Attachment Quality as Moderators of Child Maltreatment Risk for Depression and PTSD Symptoms in Adolescent Females.

Child maltreatment (CM) is a robust risk factor for adolescent depressive and post-traumatic stress disorder (PTSD) symptoms. Quality attachment relationships have been posited as a protective factor but findings are equivocal and studies have not adequately considered the complex network of interpersonal relationships that adolescents rely on. The current study applied a person-centered approach to (a) identify subgroups of adolescent females characterized by distinct patterns of attachment quality with peers, fathers, and mothers and (b) determine if the effect of maltreatment on depressive and PTSD symptoms varied as a function of distinct patterns of attachment quality. Data came from a prospective, longitudinal cohort study of 464 racially diverse and adolescent females designed to examine the developmental sequelae of substantiated CM (260 maltreated and 204 demographically matched, nonmaltreated comparisons). Latent profile analysis (LPA) revealed four profiles of attachment characterized by: (a) above-average attachment quality across all three relationships (N = 207, 44.6%); (b) below-average quality with father and friends and above-average quality with mothers (N = 128, 27.6%); (c) below-average quality across all three relationships (N = 106, 22.9%); and (d) very low-(-1 SD) quality with mothers and above-average quality with fathers and friends (N = 23, 5.0%). Moderation models revealed that cumulative maltreatment exposure resulted in greater adolescent depressive symptoms only for those with a profile of attachment consisting of very low-quality maternal attachment and high-quality father and friend attachments. Profiles did not significantly moderate the effect of maltreatment on PTSD symptoms. Results identify subgroups of maltreatment survivors most vulnerable to the development of depression in adolescence. Such groups should be targets for the provision of finite clinical resources with clinical interventions that seek to promote healthy maternal attachment relationships to mitigate the impact of maltreatment on depression.

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. To address these aims, we used a longitudinal sample of emerging adults (N = 413, Mage = 19.67, 78.0% Black, 51.1% female) who had previously participated in research assessments at age 10-12. Using a person-centered approach with latent profile analysis, we identified three classes of emerging adulthood psychopathology characterized by different levels of symptom severity and comorbidity between internalizing and externalizing symptoms. Emerging adults who experienced deprivation only, compared to those who were not maltreated, were more likely to belong to a comorbid and severe psychopathology class versus the other identified psychopathology classes. There was also a significant indirect pathway from experiences of both threat and deprivation to a high externalizing class via emotion lability/negativity. Our results contribute to current models of childhood adversity and psychopathology and have implications for interventions to prevent psychopathology among emerging adults exposed to child maltreatment.

Intergenerational effects of maternal depression and co-occurring antisocial behaviors: The mediating role of parenting-related processes.

Co-occurring maternal depression and antisocial personality disorder (ASPD) are associated with the development of psychopathology in children, yet little is known about risk mechanisms. In a sample of 122 racially diverse and economically disadvantaged families, we prospectively investigated (a) to what extent child socioemotional problems were related to maternal depression-only, ASPD-only, or the co-occurrence of both and (b) specificity in parenting-related mechanisms linking single-type or comorbid maternal psychopathology to child outcomes at age 3. Compared to mothers without either ASPD or depression, exposure to maternal depression-only and comorbid depression/ASPD predicted child problems as a function of greater parenting stress and lower maternal sensitivity. Mothers with comorbid depression/ASPD uniquely exhibited more negative parenting and had children with more socioemotional problems than mothers with depression-only. Compared to mothers with neither ASPD nor depression, mothers with depression-only uniquely impacted child difficulties via lower maternal efficacy. Study findings suggest areas of parenting intervention. (PsycInfo Database Record (c) 2023 APA, all rights reserved).

Childhood attention problems mediate effects of child maltreatment on decision-making performance in emerging adulthood.

Decision-making impairments during emerging adulthood confer risk for challenges in social and occupational roles and may increase the odds of developing health problems. Childhood maltreatment is related to maladaptation in cognitive and affective domains (e.g., executive functioning, emotion regulation) implicated in the development of decision-making capacities. This study investigates childhood maltreatment and subsequent childhood attention problems as developmental antecedents of decision making performance in emerging adulthood. At Wave 1, equal numbers of maltreated and non-maltreated children (Mage = 11.28, SD = .97; 51.5% female; mean family income: $22,530/year) were recruited to take part in a research summer camp. The current study includes a subset of participants (n = 379) from Wave 1 who completed the Cambridge Gambling Task (CGT) at Wave 2 (Mage = 19.68, SD = 1.12; 77.3% Black/African American, 11.1% White, 7.7% Hispanic, 4.0% Other race). The CGT measured decision-making performance by assessing betting behavior across trials that differed in probability of winning. ANOVA results showed that emerging adults who experienced maltreatment in childhood placed higher bets and less sensitively adjusted bets across trials varying in level of risk. Longitudinal structural equation modeling results indicated significant relationships between number of maltreatment subtypes and greater childhood inattention, controlling for IQ. In turn, greater attention problems in childhood predicted worse risk adjustment, or ability to modify betting based on the probability of winning on CGT trials. This mediated path shows one process by which maltreatment negatively affects decision making and risk taking processes in emerging adulthood.

Child maltreatment: An intergenerational cascades model of risk processes potentiating child psychopathology.

BACKGROUND: Child maltreatment poses substantial risk for compromised mental health in children. Further, child abuse and neglect are potentiated within a cascade of intergenerational and current familial risk processes that require clarification to inform understanding of adverse outcomes and direct prevention and intervention efforts. OBJECTIVE: Using a multi-informant design, the current study applied an intergenerational cascades approach to examine the interconnected pathways among several familial risk factors associated with child maltreatment and its consequences. PARTICIPANTS: Participants were 378 children (aged 10-12) and their mothers from economically disadvantaged, ethnically diverse backgrounds. The sample included maltreated children recruited via CPS records and demographically comparable non-maltreated children. METHODS: Structural equation modeling (SEM) was conducted to test sequential mediation pathways examining the independent and cascading effects of maternal history of childhood maltreatment, maternal adolescent childbearing, current maternal depression, and the child's lifetime history of maltreatment on the child's internalizing and externalizing symptoms. RESULTS: Multigenerational developmental cascades were identified. Maternal history of maltreatment predicted chronic maltreatment for offspring, which in turn predicted greater internalizing (ß = .167, p = .03) and externalizing symptoms (ß = .236, p = .005) in late childhood. Similarly, children born to mothers who began childbearing in adolescence were more likely to experience chronic maltreatment during childhood and develop subsequent symptoms. Effects were found over and above a parallel cascade from maternal maltreatment to offspring psychopathology via a maternal depression pathway. CONCLUSION: Findings reveal targets to prevent or ameliorate progressions of intergenerational risk pathways.

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. At wave 2, participants were recontacted during emerging adulthood (ages 18-22). The current study includes 391 participants (51.3% female; 77.5% Black, 11.3% white, 7.4% Hispanic, 3.8% other race). METHODS: Timing and chronicity of maltreatment exposures were coded from child protective services records using the Maltreatment Classification System. Childhood internalizing and externalizing symptoms were assessed using child- and camp counselor-report. Emerging adults completed self-report questionnaires and were interviewed about their current and past symptoms of psychopathology. Structural equation modeling was used to estimate direct and indirect links between childhood maltreatment dimensions (chronicity and timing) to adult psychopathology via childhood internalizing and externalizing. RESULTS: Child maltreatment experiences that spanned several developmental periods, including both early and later childhood stages, predicted a cascade of both internalizing and externalizing symptoms in childhood that eventuated in greater symptoms of anxiety, depression, substance use disorder, and antisocial personality disorder in emerging adulthood. CONCLUSIONS: Results suggest that chronic childhood maltreatment exposure is associated with multifinality in psychopathology presentations that can be detected in childhood and extend into emerging adulthood. Early prevention and intervention efforts to promote positive and safe parenting are essential to decrease the burden of mental health symptoms conferred by chronic maltreatment exposures on individuals, families, and public health systems.

Patterns of Child Maltreatment and the Development of Conflictual Emerging Adult Romantic Relationships: An Examination of Mechanisms and Gender Moderation.

Individuals who experienced child maltreatment are at heightened risk for involvement in conflictual romantic relationships. The aim of this study was to examine the effect of patterns of child maltreatment on the development of maladaptive romantic relationships in emerging adulthood (EA), as well as to determine whether childhood physical aggression and disinhibition mediate this risk. Utilizing a longitudinal sample of emerging adult participants (N = 398 emerging adults; Mage = 19.67 years) who took part in a summer research camp as children (Mage = 11.27 years), we employed a combination of person-centered and variable-centered methods to test study aims. Significant differences in child behavior and developmental pathways emerged not only between those who experienced maltreatment and those who did not, but also among maltreated individuals with different constellations of maltreatment experiences. Specifically, childhood aggression was a robust mechanism underlying the risk associated with chronic/multi-subtype maltreatment, and the risk associated with neglect only, for involvement in dysfunctional EA romantic relationships. Together, these findings highlight the utility of person-centered methods for conceptualizing maltreatment, identify childhood aggression as a pathway of risk, and the underscore the criticality of prevention and early intervention to interrupt the intergenerational transmission of high conflict and aggression within families.
