Childhood emotional maltreatment predicts social well-being beyond individual well-being: a daily diary study

ABSTRACT Childhood emotional maltreatment can have a profound impact on well-being. However, past research has largely focused on individual well-being, making it noteworthy to examine whether childhood emotional maltreatment predicts social well-being beyond individual well-being. To fill this gap, the current study employed a daily diary approach to investigate the independent effect of childhood emotional maltreatment on social well-being, and examined gratitude’s mediating role in the relationship. A total of 483 participants (Mage = 19.30, SDage = 2.12) completed daily surveys for 14 consecutive days. The results of the multilevel regression analysis indicated that childhood emotional maltreatment negatively and independently predicted social well-being, even after controlling for individual well- being, other forms of maltreatment (i.e. physical and sexual maltreatment), age and gender. Moreover, multilevel mediation analysis elucidated that gratitude served as a mediating factor in this association. In summary, these findings underscore the adverse effects of emotional maltreatment on social well-being and suggest gratitude as a possible intervention focus.

Differential association between childhood trauma subtypes and neurocognitive performance in adults with major depression

BackgroundNeurocognitive impairment is one of the prominent manifestations of major depressive disorder (MDD). Childhood trauma enhances vulnerability to developing MDD and contributes to neurocognitive dysfunctions. However, the distinct impacts of different types of childhood trauma on neurocognitive processes in MDD remain unclear.MethodsThis study comprised 186 individuals diagnosed with MDD and 268 healthy controls. Childhood trauma was evaluated using the 28-item Childhood Trauma Questionnaire-Short Form. Neurocognitive abilities, encompassing sustained attention, vigilance, visual memory, and executive functioning, were measured by the Cambridge Neuropsychological Testing Automated Battery.ResultsMultivariable linear regressions revealed that childhood trauma and MDD diagnosis were independently associated with neurocognitive impairment. Physical neglect was associated with impaired visual memory and working memory. MDD diagnosis is associated with working memory and planning. Interactive analysis revealed that physical/sexual abuse was associated with a high level of vigilance and that emotional neglect was linked with better performance on cognitive flexibility in MDD patients. Furthermore, childhood emotional abuse, physical abuse, and emotional neglect were revealed to be risk factors for developing early-onset, chronic depressive episodes.ConclusionThus, specific associations between various childhood traumas and cognitive development in depression are complex phenomena that need further study.

Childhood emotional maltreatment affects depression of adolescents with mood disorders: the mediating role of functions of non-suicidal self-injury

BackgroundChildhood emotional maltreatment, non-suicidal self-injury and depression are prevalent among adolescents with mood disorders. While existing model indicated that childhood emotional maltreatment, functions of non-suicidal self-injury and depression are interrelated, not much is understood about the interplay of functions of non-suicidal self-injury in the relationship between childhood emotional maltreatment and depression. Thus, the goal of this research was to ascertain how functions of non-suicidal self-injury relate to childhood emotional maltreatment and depression.MethodsThe participants were adolescents with mood disorders from three hospitals in Sichuan Province, data was collected using self-administered questionnaires, including the Childhood Trauma Questionnaire, Ottawa Self-injury Inventory-Functions, and Childhood Depression Inventory. SPSS26.0 software and PROCESS v3.3 model 4 were used for analysis.ResultsIn all, 235 adolescents (Mage=14.8, SD = 1.62) participated in the research. The functions of non-suicidal self-injury (r = 0.289, P < 0.01) and depression (r = 0.475, P < 0.01) were considerably positively connected with childhood emotional maltreatment, and the functions of non-suicidal self-injury were strongly positively correlated with depression (r = 0.364, P < 0.01). The direct impact of childhood emotional maltreatment on depression in adolescents was found to be significant (95% CI 0.434, 0.828) in the mediated effects model. Additionally, the indirect effect of childhood emotional maltreatment on depression through functions of non-suicidal self-injury was found to be significant (95% CI 0.055, 0.236), with a mediating effect value of 17.58%.ConclusionChildhood emotional maltreatment has a direct impact on depression, but it also has an indirect influence through mediation roles of functions of non-suicidal self-injury. Medical staff should take care of the mental health of adolescents hospitalized for mood disorders so that they can clarify the role of functions of NSSI in lowering depressive symptoms and improving quality of life and create more targeted and effective intervention plans.

Association of Childhood Abuse with Incident Inflammatory Bowel Disease.

A link between inflammatory bowel disease (IBD), stressful life events and psychological factors has previously been reported. Our objective was to examine the relationship between childhood emotional, physical, and sexual abuse and risk of IBD using a large cohort of female health professionals. We included participants in the Nurses' Health Study II who completed the Physical and Emotional Abuse Subscale of the Childhood Trauma Questionnaire and the Sexual Maltreatment Scale of the Parent-Child Conflict Tactics Scale in 2001. Diagnosis of IBD was determined by self-report and confirmed independently by two physicians through review of medical records. We used Cox proportional hazard modeling to estimate the risk of Crohn's disease (CD) and ulcerative colitis (UC) while adjusting for covariates. Among 68,167 women followed from 1989 until 2017, there were 146 incident cases of CD and 215 incident cases of UC. Compared to women with no history of abuse, the adjusted hazard ratios of CD were 1.16 (95% CI 0.67 - 2.02) for mild, 1.58 (95% CI 0.92 - 2.69) for moderate, and 1.95 (95% CI 1.22 - 3.10) for severe abuse (Ptrend = 0.002). We did not observe an association between childhood abuse and risk of UC. Women who reported early life severe abuse had an increased risk of CD. These data add to the growing body of evidence on the critical role of early life stressors in development of CD.

Childhood Emotional Trauma and Flourishing in Female College Students.

There are few studies that measure the effects of childhood emotional trauma on female college students' positive perceptions and attitudes toward their present lives. Therefore, this study analyzes how female college students' emotional trauma induced by child emotional abuse influences their flourishing as adults. To this end, a descriptive survey via an online platform was conducted from November 26 to December 3, 2022. The participants were 318 female college students aged 18 to 35 in South Korea, who experienced parental emotional abuse when they were younger than 18 years old. The survey was conducted to validate the moderating effects of resilience and cognitive emotion regulation strategies on the relationship between female college students' childhood emotional trauma and flourishing. The data were analyzed using descriptive statistics, t-tests, analysis of variance, Pearson's correlation coefficient, and Hayes' PROCESS macro. Self-blame, other-blame, and positive refocusing factors of the Cognitive Emotion Regulation Questionnaire were found to moderate the relationship between childhood emotional trauma and flourishing. Specifically, the self-blame strategy intensified the negative moderation effect. As flourishing depends on the degree of self-blame, fostering optimism by mitigating self-blame is necessary. The other-blame strategy attenuated the negative impact of childhood emotional trauma on flourishing. Nevertheless, this strategy can weaken emotions if individuals fail to regulate them independently. A positive refocusing strategy also effectively moderated the relationship between childhood emotional trauma and flourishing by alleviating the former's adverse effects. By contrast, resilience lacked a moderation effect. To overcome past emotional adversities and lead a flourishing life, interventions that actively utilize relational resources within the campus and regulate irrational beliefs, such as self-blame and blame toward others are necessary. These findings provide critical foundational data for the development of programs aimed at fostering a forward-thinking cognitive framework, thus enabling them to focus on future plans despite memories of emotional abuse.

Childhood emotional maltreatment and romantic relationship satisfaction: the mediating role of early maladaptive schemas

ABSTRACT Objective Survivors of childhood emotional maltreatment (CEM) often report lower levels of romantic relationship satisfaction in later life, yet the mechanisms through which this occurs are unclear. Theoretical and empirical evidence suggests a potential pathway underlying this association is early maladaptive schemas (EMS), however, research is limited. The present study sought out to clarify the association between CEM and current romantic relationship satisfaction, and whether EMS mediate this relationship. Method The final sample consisted of 230 undergraduate psychology students. An anonymous online survey was administered assessing childhood maltreatment, EMS and current romantic relationship satisfaction. Data pertaining to possible covariates were also collected. Results CEM was found to be negatively correlated with relationship satisfaction. The results of path analysis additionally revealed emotional deprivation as the only early maladaptive schema to mediate this relationship. Conclusions These findings contribute to the understanding of how CEM may be related to relationship satisfaction, via EMS. In particular, they suggest experiences of CEM may strengthen the belief that others will not meet one’s emotional needs, which in turn, may be associated with reduced levels of romantic relationship satisfaction. Implications for clinical interventions to support adult survivors of CEM are discussed.

Adverse Childhood Experiences and Suboptimal Self-Rated Health in Adulthood: Exploring Effect Modification by Age, Sex and Race/Ethnicity.

This study examined whether the relationship between adverse childhood experiences (ACEs) and self-rated health among adults in a nationally representative population is modified by age, sex, or race/ethnicity. Cross-sectional study. United States. Data from the 2020 and 2021 Behavioral Risk Factor Surveillance System were obtained from 185731 (weighted N = 47862016) persons 18years or older. The ACE cumulative score (range: 0-11) was calculated using 11 questions about childhood emotional abuse, physical abuse, sexual abuse, and household dysfunction before age 18 and classified as 0 (reference), 1, 2, 3, or ≥4. Self-rated health was divided into (excellent/very good/good [reference]) and suboptimal (fair/poor) categories. Multivariable-adjusted logistic regression was conducted to test for the interaction with age, sex, and race/ethnicity with ACEs. After adjustment for potential confounders, an increasing number of ACEs had statistically significantly higher odds of suboptimal self-rated health in a graded manner except for 1 ACE (1 ACE: aOR:1.09; 95% CI: 1.00-1.20, 2 ACEs: 1.16; 1.03-1.30, 3 ACEs: 1.17; 1.03-1.32 and ≥4 ACEs: 1.39; 1.26-1.53). There was a significant interaction between ACEs and age. Younger age (18-24years) had the strongest association for ≥4 ACEs compared to the older age groups. There was no effect modification by sex or race. ACEs should be considered when creating health-promoting interventions to improve health.

Bipolar disorder and early childhood trauma

Case Background There is a reported 48.8 million case of bipolar disorder (BD) world- wide. It can also be one of the most challenging disorders to manage clinically as patients often have poor medical compliance and numerous relapses throughout their lifetime. The etiology of this illness is still poorly understood, but it is recognized to compromise both genetic and environmental factors. Regarding the latter, abuse and instability in childhood and adolescence was reported as an important area of consideration in regard to the development and prognosis of bipolar disorder. We report here the case of a female who exemplifies the significance of early childhood experience in this disorder. Case Presentation Isabelle is a 21 year old, female, with a background history of bipolar disorder. She presented to the Cork University Hospital accident and emergency 2 weeks after discharge after a 4 week admission for a depressive episode. Isabelle was referred from the home-based team with an acute episode of mania and was detained involuntarily under the Mental Health Act. Her history is significant for childhood neglect, physical, emotional and sexual abuse, along with multiple foster care placements. She was managed as an inpatient with antipsychotics and a mood stabilizer before being discharged after a lengthy, arduous, admission. Conclusion Childhood trauma is an important consideration in BD. Therefore, practitioner awareness of the role of such trauma with regard to its etiology and prognosis is of great importance. It is also essential to the practice of preventive medicine. Patient Consent Obtained: Yes

Childhood emotional maltreatment and emerging adults’ body dissatisfaction: Self-compassion and body surveillance as explanatory mechanisms

The association between childhood emotional maltreatment and body dissatisfaction has been widely identified. However, the explanatory mechanisms for this association remain unclear. Guided by the Stress Process Model, the present study tested the potential mediating roles of self-compassion and body surveillance in the associations between emotional maltreatment (i.e., emotional abuse and neglect) and body dissatisfaction. Three-wave, self-report survey data were collected from 668 Chinese young adults (66.8 % female, Mage = 19.96 years old, SD = 1.25) with a 6-month between-wave interval. Results demonstrated that childhood emotional neglect (recalled at Time 1) was positively associated with body dissatisfaction (at Time 3) through a serial mediating pathway from self-compassion (at Time 1) to body surveillance (at Time 2). In contrast, no links involving childhood emotional abuse were identified. Findings suggest that the compromised emotion regulation capacity related to self-care and the subsequent self-objectification could be key processes through which childhood emotional deprivation would be positively associated with later body dissatisfaction. Accordingly, prevention and intervention efforts aimed at combating young adults’ body image issues with early adversity of emotional deprivation could integrate emotion regulation training (that can enhance self-care) and cognitive-behavioral techniques (that may reduce body surveillance) into extant programs to enhance effectiveness.

Adaptation of Childhood Emotional Abuse Measurement Instrumen in Indonesia

Childhood emotional abuse has long-term impacts on individuals. A specific measuring instrument to measure the history of childhood emotional abuse in Indonesian adolescents is needed. The current study adapted the Emotional Abuse Questionnaire developed by Momtaz et al. (2022) into an Indonesian version (ID-EAQ). Participants in this study were 100 adolescents aged 17-21 years, selected using a purposive sampling technique. The adaptation was carried out with the guidance of the International Test Commission (2016). The results showed that the ID-EAQ has a high level of validity and reliability with a value of 0.921. It can be concluded that the ID-EAQ is a valid and reliable measuring instrument to measure the history of childhood emotional abuse in adolescent samples

Child maltreatment and insomnia symptoms among Chinese university students: the buffering role of self-efficacy.

Insomnia symptoms represent a significant public health concern, as it engenders substantial long-term health consequences. Considerable research has established the detrimental impacts of child maltreatment on sleep problems among university students. However, the role of self-efficacy in the association between childhood maltreatment and insomnia remains unclear. This study aimed to examine the associations between child maltreatment and insomnia symptoms among university students, and to investigate whether self-efficacy moderated the effects of child maltreatment on insomnia symptoms. A total of 2014 participants with random cluster sampling method were recruited from Jinan University in Guangzhou, China, from October 2022 to November 2022. Adjusting for covariates, the results of multiple logistic regression indicated that the participants with the experience of any type of child maltreatment (odds ratio [OR] 2.24, 95% confidence interval [CI] 1.63-3.07), childhood emotional abuse (OR 2.58, 95% CI 1.95-3.41), childhood emotional neglect (OR 1.16, 95% CI 0.87-1.54), childhood physical abuse (OR 2.15, 95% CI 1.60-2.8), childhood physical neglect (OR 2.19, 95% CI 1.64-2.92), childhood sexual abuse (OR 1.98, 95% CI 1.46-2.68) were more likely to report insomnia symptoms than those without. Individuals reporting one-two types and three-five types of child maltreatment were 1.81 times (95% CI 1.30-2.52) and 3.77 times (95% CI 2.58-5.50) more likely to report insomnia symptoms than those reporting zero types of child maltreatment, respectively. Furthermore, robust linear regression analysis revealed that self-efficacy moderated the associations between child maltreatment and insomnia symptoms (β = 0.007, 95% CI 0.004-0.010). These findings underscore the need for integrated mental health education, support services, and faculty training to address the impact of child maltreatment on insomnia symptoms among university students. Policy recommendations include advocating for comprehensive mental health services, incorporating self-efficacy initiatives, and fostering community engagement for a holistic approach to student well-being.

The Influence of Childhood Emotional Abuse and Neglect on Love Addiction: The Indirect Effect of Vulnerable Narcissism Among Female and Male Emerging Adults.

Childhood maltreatment is a key precursor to vulnerable narcissism since it likely lead to a narcissistic injury that triggers defenses against rage and abandonment. In later life, this pattern may contribute to a maladaptive model of love relationships. The present study explored the association between different types of childhood maltreatment (i.e., emotional, physical, and sexual abuse; physical and emotional neglect) and love addiction via vulnerable narcissism in a community sample of 505 cisgender emerging adults (M = 24.90, SD = 2.67; 76.6% assigned female at birth (AFAB); 68.5% heterosexual) residing in Italy. Data collection relied on self-report questionnaires administered online through the Qualtrics platform, and study hypotheses were tested using structural equation modeling. The results showed that childhood emotional abuse and emotional neglect directly influenced love addiction, while physical and sexual abuse, as well as physical neglect, showed no significant effects. Greater childhood emotional abuse and neglect were associated with increased vulnerable narcissism, leading to higher levels of love addiction. Gender differences emerged, with the indirect effect of vulnerable narcissism on the relationship between emotional neglect and love addiction significant only for AFAB. The findings emphasize the risk of love addiction in emerging adults with a history of childhood emotional abuse and neglect, highlighting the importance of addressing childhood emotional maltreatment and vulnerable narcissistic personality traits in interventions to treat this condition.

Disentangling general and sport-specific risk factors for anxiety and depression in a mixed sample of athletes and non-athletes

The present study was designed to assess whether competitive athletes and non-athletes differ in terms of certain personality traits linked to atypicalities in emotion awareness and regulation, and whether being an athlete accounts for unique variance in symptoms of anxiety and depression when these traits and exposure to childhood emotional abuse are held constant. In order to address these questions, we had 483 undergraduates (Mage = 19.7 years; 75.8% female), including 228 athletes and 255 non-athletes, complete self-report measures of personality (alexithymia, sensory processing sensitivity or SPS, and anxiety sensitivity or AS), exposure to emotional abuse in childhood, pandemic-related stress, anxiety, and depression. Recreational and elite athletes scored lower on SPS and depression than non-athletes, and recreational athletes also scored lower than non-athletes on AS. However, involvement in competitive sport did not predict depression or anxiety when other variables were controlled for. Alexithymia, AS, and childhood emotional abuse predicted depression, and SPS, AS, and childhood emotional abuse predicted anxiety. The same pattern was seen in a subgroup of athletes (n = 91) who had recently been coached, except that in this subgroup exposure to emotionally abusive coaching was found to be an additional risk factor for anxiety. These findings help to disentangle general and sport-specific risk factors for anxiety and depression and may have important implications for preventing and treating these problems in athletes and non-athletes alike.

Understanding the relationship between childhood emotional abuse and neglect and psychological distress in pregnant women: the role of prenatal attachment

BackgroundChildhood abuse and neglect pose important risk factors for the development of psychopathology during pregnancy. However, only a few studies have assessed the effects of a specific type of abuse during the perinatal period, namely, psychological maltreatment, which includes emotional abuse and neglect. These studies have found that women who have experienced psychological maltreatment exhibit higher levels of antenatal depressive symptoms and greater difficulties forming attachment with their babies than women who have not experienced this kind of adversity. The aim of this study was to examine how emotional abuse and neglect experiences may favor the occurrence of psychological distress in pregnant women, and whether prenatal attachment might explain this association.MethodsParticipants comprised 128 Italian pregnant women ranging in age from 21 to 46 years (Mage = 33.4; SD = 6.10). Women responded to the following self-report instruments: CECA.Q and CTQ-SF, for the assessment of psychological maltreatment experiences; MAAS, for the evaluation of prenatal attachment; and PAMA, for the assessment of perinatal psychological distress.ResultsPearson correlations revealed a positive association between childhood neglect and perinatal psychological distress and a negative association between childhood neglect and prenatal attachment scores. No significant correlations were found for emotional abuse. Perinatal psychological distress was negatively associated with prenatal attachment. Mediation analyses showed significant associations between childhood neglect and the dimensions of perinatal affectivity and prenatal maternal attachment. Prenatal maternal attachment mediated the relationship between neglect and perinatal psychological distress.ConclusionsThe transition to motherhood is a sensitive period, particularly for women who have experienced abuse and neglect during childhood. These experiences may negatively impact a woman’s disposition to emotionally and behaviorally engage in the formation of a bond with their unborn baby. These results may have important prevention and clinical implications and thus warrant further exploration.

The relationship of childhood maltreatment, adult sexual victimization, depressed mood and symptoms of trauma with fear of childbirth

Background: Fear of childbirth (FoB) is experienced to some degree by most pregnant people and can be intense enough to merit treatment. Despite significant research on the topic of FoB, studies investigating various forms of maltreatment and mental health symptoms in relation to FoB are very limited. In particular, studies including multiple forms of maltreatment along with mental health symptoms as predictors of FoB are extremely limited. We sought to fill this gap and clarify the relative contributions of these variables to the prediction of FoB. Methods: This was a secondary analysis of data from pregnant people in Canada. Participants (N = 881) provided demographic and reproductive history information, completed self-report measures of FoB, childhood maltreatment (multiple forms), adult sexual victimization, depressed mood and symptoms of posttraumatic stress disorder (PTSD). They were also administered a diagnostic interview to assess for specific phobia, FoB. Analyses included descriptive information, Wilcoxon rank sum tests, linear and logistic regression, and path analysis. Results: Most forms of maltreatment showed some association with increased FoB. However, when assessed together, only emotional maltreatment remained a significant predictor of FoB. Both depressed mood and symptoms of PTSD contributed more to FoB than maltreatment, and mediated the relationship of emotional maltreatment with FoB. The only direct effects of childhood emotional maltreatment on FoB were for fears of medical interventions and feelings of embarrassment during labour and delivery. Limitations: Study findings fill significant gaps in our understanding of the relationship between maltreatment, mental health symptoms and FoB. However, the study sample was limited to Canadian participants, most of whom were socio-economically advantaged, cis-gender women of European descent, thus limiting the generalizability of the findings. Further, as childhood maltreatment and sexual assault experiences in adulthood were reported retrospectively, study findings are also vulnerable to recall bias. Conclusions: Findings contribute to our understanding of the relationship between childhood maltreatment, adult sexual victimization, mental health and FoB. These findings can facilitate future research and improved care via a focus on depressed mood, symptoms of PTSD, emotional maltreatment and specific fears of medical interventions and social discomfort as significant contributors to one's experience of FoB.

Vulnerable Narcissism and Emotion Dysregulation as Mediators in the Link between Childhood Emotional Abuse and Binge Watching.

Individuals who have faced childhood emotional abuse (CEA) may develop vulnerable narcissistic tendencies and experience difficulties in regulating their emotions. These psychological vulnerabilities can contribute to the adoption of binge watching as a maladaptive coping mechanism. The present study aimed to investigate the potential mediating role of vulnerable narcissism and emotion dysregulation in the relationship between CEA and binge watching. Additionally, this study examined whether this model was gender-invariant. A sample of 1082 emerging adults, aged 18 to 25 (50% women), completed self-report questionnaires. The results revealed significant direct and indirect relationships among all the variables of interest, and the model was found to be invariant across genders. Notably, both men and women who experienced CEA and exhibited higher levels of vulnerable narcissism and emotion dysregulation reported engaging in higher levels of binge watching. These findings highlight the importance of the early identification of CEA, the implementation of targeted interventions, and the provision of trauma-informed care to address the negative consequences of CEA and mitigate the development of binge-watching behaviors. Moreover, the results emphasize the need for tailored prevention and intervention programs that address vulnerable narcissism and emotion dysregulation as potential pathways to inform effective therapeutic strategies.

The cross-lagged relationship between adolescent school bullying and loneliness——The predictive role of childhood emotional maltreatment

School bullying and loneliness have become common problems in adolescent interpersonal relationships. The increase of school bullying in recent years is closely related to adolescents’ loneliness, and loneliness may also affect the implementation of school bullying. Meanwhile, childhood emotional maltreatment plays an important role in interpersonal relationship problems triggered by adolescence, which has attracted a lot of attention from researchers. The purpose of this study was to explore the mutual and transactional relationship between loneliness and school bullying under childhood emotional maltreatment. A total of 1214 Chinese high school students (Mage = 15.46, SD = 0.71) completed the measures of childhood emotional maltreatment, loneliness, and school bullying. They provided data in three waves (T1, T2, and T3, 6 months apart). The results reality that loneliness under childhood emotional abuse and school bullying are correlated and that childhood emotional abuse significantly predicts loneliness and school bullying in adolescence. Specifically, loneliness positively predicted school bullying, but the predictive effect of school bullying on loneliness was influenced by gender. Moreover, childhood emotional maltreatment can lead to the perpetration of school bullying by triggering loneliness in adolescents. The results of the study, although unexpected, also reveal social problems and provide new ideas for studying adolescent interpersonal problems.

Childhood Maltreatment and Longitudinal Epigenetic Aging

Child physical and emotional abuse and neglect may affect epigenetic signatures of accelerated aging several years after the exposure. To examine the longitudinal outcomes of early-childhood and midchildhood exposures to maltreatment on later childhood and adolescent profiles of epigenetic accelerated aging. This cohort study used data from the Future of Families and Child Wellbeing Study (enrolled 1998-2000), a US birth cohort study with available DNA methylation (DNAm) data at ages 9 and 15 years (assayed between 2017 and 2020) and phenotypic data at birth (wave 1), and ages 3 (wave 3), 5 (wave 4), 9 (wave 5), and 15 (wave 6) years. Data were analyzed between June 18 and December 10, 2023. Emotional aggression, physical assault, emotional neglect, and physical neglect via the Parent-Child Conflict Tactics Scale at ages 3 and 5 years. Epigenetic accelerated aging (DNAmAA) was measured using 3 machine learning-derived surrogates of aging (GrimAge, PhenoAge, and DunedinPACE) and 2 machine learning-derived surrogates of age (Horvath and PedBE), residualized for age in months. A total of 1971 children (992 [50.3%] male) representative of births in large US cities between 1998 and 2000 were included. Physical assault at age 3 years was positively associated with DNAmAA for PhenoAge (β = 0.073; 95% CI, 0.019-0.127), and emotional aggression at age 3 years was negatively associated with PhenoAge DNAmAA (β = -0.107; 95% CI, -0.162 to -0.052). Emotional neglect at age 5 years was positively associated with PhenoAge DNAmAA (β = 0.051; 95% CI, 0.006-0.097). Cumulative exposure to physical assault between ages 3 and 5 years was positively associated with PhenoAge DNAmAA (β = 0.063; 95% CI, 0.003-0.123); emotional aggression was negatively associated with PhenoAge DNAmAA (β = -0.104; 95% CI, -0.165 to -0.043). The association of these measures with age 15 years PhenoAge DNAmAA was almost fully mediated by age 9 years PhenoAge DNAm age acceleration. Similar patterns were found for GrimAge, DunedinPACE, and PhenoAge, but only those for PhenoAge remained after adjustments for multiple comparisons. In this cohort study, altered patterns of DNAmAA were sensitive to the type and timing of child maltreatment exposure and appeared to be associated with more proximate biological embedding of stress.

Child Abuse and Neglect and Obsessive–Compulsive Personality Traits: Effects of Attachment, Intolerance of Uncertainty, and Metacognition

AbstractChild Abuse and Neglect (CAN) is extensively implicated as a risk factor preceding the development of Obsessive–Compulsive Personality Traits (OCPT). Nevertheless, the majority of individuals with a history of CAN do not go on to develop OCPT. To date, little research has investigated potential model networks that may help contribute to explaining why CAN sometimes leads to OCPT and not at other times. Thus, this study aimed to investigate whether attachment-anxiety, intolerance of uncertainty, and metacognition have indirect effects in the association between CAN and OCPT in various network models. Undergraduate psychology students (N = 291) participated in an anonymous 30-min online survey consisting of a series of self-report questionnaires regarding child abuse and neglect, attachment, intolerance of uncertainty, metacognition, OCPT, and depression. Bootstrapped serial mediation revealed attachment-anxiety and intolerance of uncertainty had a serial-mediation effect in the association between CAN and OCPT. Serial mediation was not found for metacognition and attachment-anxiety. However, metacognition alone mediated between child emotional abuse and OCPT. These findings expand our currently limited knowledge regarding the etiology of OCPT and suggest that attachment-anxiety, intolerance of uncertainty, and metacognition may be important contributors for understanding the development of OCPT following CAN exposure. The potential clinical utility for both assessment and treatment are discussed.
