Attachment insecurity as a mediator of the relationship between childhood trauma and adult dissociation

This study aimed to investigate whether attachment insecurity mediates the relationship between childhood trauma and adult dissociation, specifically with regard to individual forms of childhood maltreatment. Psychiatric outpatients who visited a specialized trauma clinic (n = 115) participated in the study. Data were collected via the Childhood Trauma Questionnaire, Revised Adult Attachment Scale, and Dissociative Experience Scale. Structural equation modeling and path analysis were performed to analyze the mediating effects of attachment insecurity on the relationship between childhood trauma and adult dissociation. Greater childhood trauma was associated with higher dissociation, and the relationship between them was fully mediated by attachment anxiety. In path analysis of trauma subtypes, the effects of emotional abuse, physical abuse, and physical neglect as a child on adult dissociation were found to be fully mediated by attachment anxiety. The effect of sexual abuse on dissociation was mediated by a synergistic effect from both attachment anxiety and attachment avoidance. Regarding emotional neglect, a countervailing interaction was discovered between the direct and indirect effects thereof on dissociation; the indirect effect of emotional neglect on dissociation was partially mediated by attachment insecurity. Specific aspects of attachment insecurity may help explain the relationships between individual forms of childhood trauma and adult dissociative symptoms. Tailored treatments based on affected areas of attachment insecurity may improve outcomes among patients with dissociative symptoms and a history of childhood trauma.     

Depersonalization,adversity, emotionality,and coping with stressful situations

Depersonalization is defined as persistent or recurrent episodes of feeling detached or estranged from a sense of self and the world. This study addressed the primary question: Do nonclinical individuals who endorse high symptomatic depersonalization have inherently more intense emotional responses, along with more childhood adversity and past trauma? In this IRB approved study, participants who met clinical levels of depersonalization (n = 43, 16.3%) were compared to a group without clinical levels of depersonalization (n = 221, 83.7%). Adverse childhood experiences, adult traumatic events, emotional overexcitability, coping strategies under stress, and anxiety were examined in both groups. The variables to assess depersonalization severity included the Dissociative Experience Scale-II, Cambridge Depersonalization Scale, and Multiscale Dissociation Inventory. The results indicated that clinical levels of depersonalization were identified in 16.3% of the sample. The high depersonalization group had significantly more adverse childhood experiences, in particular, emotional abuse and neglect. They also experienced more adult traumatic events, higher levels of anxiety, more emotional overexcitability, and they employed a less adaptive emotion-oriented coping strategy under stress. It is recommended that treating depersonalization symptoms should include examining childhood adversity, especially emotional abuse and neglect. Based on study findings, emotion regulation skills should be promoted to help individuals with elevated depersonalization manage their emotion-oriented coping strategies, anxiety, and emotional overexcitability.     

Genetic Variation at the TPH2 Gene Influences Impulsivity in Addition to Eating Disorders

Genes are involved in eating disorders (EDs) and self-induced vomiting (SV), a key symptom of different types of EDs. Perfectionism and impulsivity are potential risk factors for EDs. TPH2 (tryptophan hydroxylase 2) SNP rs1473473 was previously associated with anorexia nervosa and EDs characterized by SV. Could perfectionism or impulsivity be underlying the association between rs1473473 and EDs? Genetic association between TPH2 SNP rs1473473 and perfectionism or impulsivity was first evaluated in a random control group (N = 512). The associations obtained in this control group were subsequently tested in a group of patients with an ED (N = 267). The minor allele of rs1473473 (OR = 1.49) was more frequent in impulsive controls, but also in impulsive patients with an ED (OR = 1.83). The largest effect was found in the patients with an ED characterized by SV (OR = 2.51, p = 0.02). Genetic variation at the TPH2 gene appeared to affect impulsivity which, in turn, might predispose to the SV phenotype.     

The relation of dissociation and mind wandering to unresolved/disorganized attachment: an experience sampling study

Individuals with unresolved/disorganized representations of childhood trauma (U/d attachment) report more psychological distress than others, but little is known about their everyday mentation. In the present study adults with childhood trauma (N = 45) completed the Berkeley-Leiden Adult Attachment Questionnaire-Unresolved (BLAAQ-U) and the Adult Attachment Interview (AAI), and reported everyday mentation during 5 days of experience sampling. The BLAAQ-U and the AAI showed a medium association with each other, but only the former significantly predicted negative affect, dissociation, and low control/awareness of mentation. Contrary to our predictions, U/d attachment did not significantly predict mind wandering, but the BLAAQ-U predicted endorsements of a negative mind wandering style. U/d attachment, as assessed by both instruments, was associated with the Poor attentional control style and beliefs in anomalous mental phenomena. Experience sampling is a valuable way to investigate everyday experiences in individuals with U/d attachment.     

Childhood abuse and neglect,attachment states of mind,and non-suicidal self-injury

This investigation examined preoccupied attachment states of mind as both a risk factor for non-suicidal self-injury (NSSI) and as a mechanism by which prospectively assessed childhood experiences of abuse and neglect predicted the frequency/severity of NSSI behavior up to age 26 years in 164 individuals (83 females) who were followed from birth in the Minnesota Longitudinal Study of Risk and Adaptation. Preoccupied (but not dismissing) states of mind regarding both childhood caregivers and adult romantic partners were correlated with more frequent/severe NSSI. Furthermore, preoccupied states of mind regarding caregivers partially accounted for the association between childhood abuse/neglect and NSSI. This work represents a rare prospective test of a developmental psychopathology framework for understanding NSSI behavior, in which atypical caregiving experiences are carried forward through attachment representations of caregivers that reflect behavioral risk.     

Childhood abuse and neglect histories in low-income women: prevalence in a menopausal population

OBJECTIVES: To examine the prevalence of self-reported childhood abuse and neglect in a primary care population of menopausal women. DESIGN: A cross-sectional questionnaire-based study. RESULTS: Three of four women (119/160, 74%) reported histories of childhood abuse and neglect. The prevalence of emotional abuse, physical abuse, sexual abuse, emotional neglect, and physical neglect were 43%, 35%, 33%, 49%, and 44%, respectively. Eleven percent of the sample reported maltreatment in all five categories of trauma. Fifteen percent of women studied met criteria for severe-extreme levels of maltreatment, usually in more than one category. CONCLUSIONS: A high prevalence of self-reported childhood trauma was detected in our low-income population of menopausal women attending primary care clinics. Because of the potential impact of childhood trauma on physical and mental health, clinicians need to inquire about childhood maltreatment in women of menopausal age and appropriately refer women to mental health intervention and treatment.     

Preliminary data on oxytocin modulation of neural reactivity in women to emotional stimuli of children depending on childhood emotional neglect

Sensitivity for rewarding cues and distress signals from children is fundamental to human caregiving and modulated by the neuropeptide oxytocin. In a functional magnetic resonance imaging study, we investigated whether oxytocin regulates neural responses to reward or distress cues form children. In a placebo-controlled, within-subject design, we measured neural responses to positive, negative, and neutral cues from children in 22 healthy female subjects who received oxytocin (24 IU) versus placebo. Further, based on current literature, we hypothesized that oxytocin effects are modulated by experiences of childhood trauma. The task elicited valence-specific effects—positive images activated the ventromedial prefrontal cortex, left anterior cingulate cortex, and right putamen, and images of children in distress activated the bilateral amygdala, hippocampus, and right medial superior frontal cortex. The effects of oxytocin depended on subjective reports of childhood emotional neglect. Self-reported neglect interacted with oxytocin administration in the amygdala, hippocampus, and prefrontal areas. In individuals with higher scores of emotional neglect, oxytocin increased neural reactivity of limbic structures to positive and neutral images. Our findings need replication in larger samples and can therefore be considered preliminary but are in line with the recent literature on the modulating effect of childhood adversity on the sensitivity to oxytocin administration.     

Maternal Childhood Maltreatment History and Child Mental Health: Mechanisms in Intergenerational Effects

The objectives of this study were to examine whether a maternal history of maltreatment in childhood has a detrimental impact on young children’s mental health and to test theoretically and empirically informed pathways by which maternal history may influence child mental health. Mother–child dyads (N = 187) were evaluated between birth and 64 months of age via home and laboratory observations, medical and child protection record reviews, and maternal interviews to assess maternal history of childhood maltreatment and microsystem and exosystem measures of the caregiving context, including child maltreatment, maternal caregiving quality, stress exposures, and social support. When the children were 7 years of age, mothers and teachers reported on child emotional and behavioral problems. Analyses examined whether the caregiving context variables linked maternal maltreatment history with child emotional and behavioral problems, controlling for child sex (54% male), race/ethnicity (63% White), and family sociodemographic risk at birth. Maltreated mothers experienced greater stress and diminished social support, and their children were more likely to be maltreated across early childhood. By age 7, children of maltreated mothers were at increased risk for clinically significant emotional and behavioral problems. A path analysis model showed mediation of the effects of maternal childhood maltreatment history on child symptoms, with specific effects significant for child maltreatment. Interventions that reduce child maltreatment risk and stress exposures and increase family social support may prevent deleterious effects of maternal childhood maltreatment history on child mental health.     

The Impact of Intimate Partner Violence Exposure in Adolescence and Emerging Adulthood: A Developmental Psychopathology Approach

Despite increased attention on parental intimate partner violence (IPV) exposure, a relative paucity of research has examined the developmental consequences of this traumatic experience within a life span approach. The aim of the present study was to examine how parental IPV exposure may relate to mental health during the transition from adolescence to emerging adulthood. Furthermore, we examined whether the impact of parental IPV exposure was unique from more commonly studied maltreatment experiences, specifically neglect and physical abuse. A large, racially and ethnically diverse sample (N_baseline = 1,042; 56% female; M_age = 15.1, SD = 0.79; 31.4% Hispanic, 29.4% White, 27.9% African American, 3.6% Asian, 7.7% biracial or other) of adolescents completed a baseline assessment for parental physical IPV exposure and maltreatment as well as measures for symptoms of depression, posttraumatic stress, and substance use, annually for 6 consecutive years. Mixed-level modeling was used to examine how parental IPV exposure was uniquely associated with different patterns of mental health across developmental epochs. Findings demonstrated a multifaceted relation with mental health. For internalizing symptoms, the effect was pronounced during adolescence, and neglect increased the risk for depression symptomatology. Meanwhile, parental-IPV-exposed adolescents were at increasing risk for substance use as they aged into adulthood. Symptom levels and trajectories were independent and distinct from maltreatment experiences. This study helps illuminate parental IPV exposure’s unique influence on well-being during vulnerable developmental periods. It also calls attention to the importance of developing suitable intervention/prevention programs to target this vulnerable population.     

Maternal attachment style,sensitivity, and infant obesity risk in low-income,Latino families

ABSTRACT

Disparities in childhood obesity highlight the need for research to identify its early predictors in high-risk populations, such as low-income, Latino families. In the current study, the first of its kind in a low-income Latino sample (N = 55; M _{child age} = 12.74 months, SD = 3.96), we investigated whether mothers’ self-reported attachment style predicted their infants’ weight-for-length (WFL; an early indicator of childhood obesity). We also explored whether observed maternal sensitivity, coded from a video-recorded semi-structured play assessment, mediated this association. We found a significant direct effect of maternal attachment style on infants’ WFL z-scores (c’ = ?0.68, SE = 0.22, p = .004). Infants of mothers who classified themselves as secure had lower WFL z-scores than infants of insecure mothers (avoidant or anxious). Maternal sensitivity did not mediate this association, but was positively associated with infant WFL z-scores. We discuss implications of these findings for future research.     

The significance of attachment security for children’s social competence with peers: a meta-analytic study

This meta-analytic review examines the association between attachment during the early life course and social competence with peers during childhood, and compares the strength of this association with those for externalizing and internalizing symptomatology. Based on 80 independent samples (N = 4441), the association between security and peer competence was significant (d = 0.39, CI 0.32; 0.47) and not moderated by the age at which peer competence was assessed. Avoidance (d = 0.17, CI 0.05; 0.30), resistance (d = 0.29, CI 0.09; 0.48), and disorganization (d = 0.25, CI 0.10; 0.40) were significantly associated with lower peer competence. Attachment security was significantly more strongly associated with peer competence than internalizing (but not externalizing) symptomatology. Discussion focuses on the significance of early attachment for the development of peer competence versus externalizing and internalizing psychopathology.     

Psychophysiological Responses to Emotional Stimuli in Children and Adolescents with Autism and Fragile X Syndrome

Individuals with autism demonstrate atypical and variable responses to social and emotional stimuli, perhaps reflecting heterogeneity of the disorder. The goal of this study was to determine whether unique profiles of psychophysiological responses to such stimuli could be identified in individuals diagnosed with autism spectrum disorder (ASD), with fragile X syndrome (FXS), and with comorbid autism and fragile X syndrome (ASD + FXS), and in typically developing (TYP) individuals. This study included 52 boys (ages 10–17): idiopathic ASD (n = 12), FXS (n = 12), comorbid ASD + FXS (n = 17), and TYP (n = 11). Physiological responses, including potentiated startle, electrodermal response, heart rate variability, and vagal tone, were collected concurrently while participants viewed emotionally evocative pictures of human faces or nonsocial images. Although some of these measures have been utilized separately for investigations on these diagnostic groups, they have not been considered together. Results using Kruskal-Wallis one-way analysis of variance by ranks indicate statistically significant differences in distributions of autonomic regulation responses between groups. The most notable differences were between the ASD group and both the FXS groups on measures of sympathetic activity, with FXS groups evincing increased activity. Also, both the ASD and ASD + FXS groups showed significantly decreased parasympathetic activity compared with FXS and TYP groups. In addition, the ASD + FXS group demonstrated a unique distribution of startle potentiation and arousal modulation. This study provides evidence that autonomic arousal and regulation profiles could be useful for distinguishing subgroups of autism and shed light on the variability underlying emotional responsivity.     

Couple relationship quality and offspring attachment security: a systematic review with meta-analysis

This paper provides a meta-analytic examination of strength and direction of association between parents’ couple relationship quality and early childhood attachment security (5 years and under). A comprehensive search of four EBSCOhost databases, Informit, Web of Science, and grey literature yielded 24 studies meeting eligibility criteria. Heterogeneity of the couple quality construct and measurement was marked. To disaggregate potentially differentially acting factors, we grouped homogeneous studies, creating two predictor variables defined as “positive dyadic adjustment” and “inter-parental conflict”. Associations of each construct with offspring attachment security were examined in two separate meta-analyses. Inter-parental conflict was inversely associated (8 studies, k = 17, r = ?0.28, CI = [?0.39 to ?0.18]), and dyadic adjustment was not associated with offspring attachment security (5 studies, k = 12, r = 0.14, CI = [?0.03 to 0.32]). The study supports finer distinctions of couple relationship constructs and measurement in developmental research, assessment, and intervention.     

The association of family support and wellbeing in later life depends on adult attachment style

The current study examines the association between family support and wellbeing in the elderly, paying particular attention to the possible moderating role of attachment style. Data from a community-dwelling, ethnically diverse, elderly sample (N = 1118) were analyzed to determine the best linear combination of emotional support, instrumental support, and attachment styles predicting wellbeing. Emotional support generally was associated with higher wellbeing whereas instrumental support was related to decreased wellbeing. As expected, however, these associations were qualified by attachment style. Receiving emotional support had stronger positive and instrumental support less negative effects on the wellbeing of elderly individuals with higher attachment security. Given increased longevity, family networks may become important sources of support for the elderly. Work detailing when, how, and for whom particular types of family support are beneficial is a key agenda within developmental psychology and social gerontology.     

Maternal mentalization affects mothers’ – but not children’s – weight via emotional eating

Previous research on childhood obesity has shown that maternal obesity is an important risk factor for this malady. Because biological and environmental factors are able to explain the transgenerational transmission of obesity only in part, psychological risk factors (e.g., emotional eating) have become more important in recent research. As maternal mentalization – which lays the foundation for the child’s ability to regulate his/her emotions – has not yet been investigated, we examined the effects of mentalization on maternal and childhood obesity. By investigating groups of obese (n = 30) and normal-weight (n = 30) mothers and their children aged 18 to 55 months, we found, contrary to our expectations, that obese mothers’ mentalization (Reflective Functioning Scale) was similar to that of mothers with normal weight and that mentalization showed no direct effect on the child’s weight. However, we found hints of an indirect influence of mentalization via emotional eating on mothers’ but not on children’s weight and via mother–child attachment (Attachment Q-Set) on children’s weight. Possible reasons for these inconclusive effects are discussed.     

Childhood maltreatment and internalized shame in adults with a diagnosis of bipolar disorder

Relatively little is understood regarding the aetiology of bipolar disorder (BD) other than for the influence of a large genetic component on the development of the disorder and the impact of stressful life events on changes in current mood. However, amongst a range of psychiatric diagnoses, research consistently demonstrates a higher frequency of reports of childhood abuse and neglect compared with individuals in the general population. In addition, those who report experiences of childhood maltreatment also report high levels of internalized shame in adulthood, although there is little research demonstrating this association amongst clinical populations. An adult sample of 35 participants with a diagnosis of BD and a control group of 35 participants with no psychiatric diagnoses completed measures of childhood abuse and neglect, and internalized shame. Participants in the BD group reported a significantly greater frequency of high levels of childhood trauma compared with participants in the control group, with the reported frequency of childhood emotional abuse and neglect being particularly high. Levels of current internalized shame were also significantly higher amongst participants in the BD group. Significant correlations were observed between current internalized shame and reports of childhood emotional abuse and neglect. Clinical implications of the study's findings are discussed, and limitations of the methodology are considered. Copyright ? 2011 John Wiley & Sons, Ltd. KEY PRACTITIONER MESSAGE: The frequency of reports of childhood trauma would appear to be higher amongst adults with a diagnosis of BD compared with individuals with no psychiatric diagnoses. Levels of internalized shame in adulthood are also likely to be higher than those in the general population, although the current literature does not shed light on the relationship between childhood abuse and neglect, mood-related behaviour, and shame. Experiences of childhood abuse and neglect, particularly childhood emotional abuse and emotional neglect, are likely to be frequently reported by clients with a diagnosis of BD. Clinicians should therefore explicitly consider these experiences in their assessment, formulation and intervention with clients with a diagnosis of BD.

Inhibited symptoms of Attachment Disorder in children from institutional and foster care samples

ABSTRACT

The main objective of the article was to study the prevalence of symptoms of the inhibited attachment disorder depending on type and quality of the caregiving environment. Analyses were based on data of a sample of institutionalized children from Georgia (N = 16), and two samples of foster children from Georgia (N = 27) and Germany (N = 55). Inhibited attachment disorder symptoms were assessed by the Disturbances of Attachment Interview (DAI) and the Rating of Inhibited Attachment Behavior (RInAB). Further assessments included behavior problems in children, quality of caregiving behavior in foster parents/caregivers, and presence of preferred caregiver in the institution. Regarding inhibited attachment behavior, expected differences between institutional (high scores) and foster samples (low scores) found for both measures (RInAB and DAI), and convergent validity between these measures was found in the institutional sample, but not in the foster samples. There were also indications of construct validity (regarding preferred caregiver in institution and caregiver supportive presence). The findings also suggest methodological issues brought about by skewed distributions of positive and negative measures in high-risk and low-risk samples, respectively.     

Developmental Origins of Rumination in Middle Childhood: The Roles of Early Temperament and Positive Parenting

Rumination, a thinking style characterized by a repetitive inward focus on negative cognitions, has been linked to internalizing disorders, particularly depression. Moreover, research suggests that rumination may be a cognitive vulnerability that predisposes individuals to psychopathology. Surprisingly little is known, however, about the etiology and development of rumination. The present study examined the role of specific components of child temperamental negative emotionality (sadness, fear, anger) and effortful control (inhibition), as well as parenting behaviors during early childhood on the development of rumination in middle childhood. Early childhood (age 3) temperament and parenting behaviors were assessed observationally and rumination was self-reported in middle childhood (age 9) in a large community sample (N = 425; 47.1% female). Two significant interactions emerged. First, temperamental anger interacted with inhibitory control (IC) such that high anger and low IC predicted higher levels of rumination, whereas low anger and low IC predicted lower levels of rumination. Second, IC interacted with parenting such that children with low IC and positive parenting had lower levels of rumination. In contrast, children with high IC reported similar levels of rumination regardless of parenting quality. Overall, these findings highlight the interplay of early IC with temperamental anger and positive parenting in the development of ruminative tendencies in middle childhood.     

Brief iPad-Based Assessment of Cognitive Functioning with ImPACT® Pediatric

ImPACT® Pediatric is an examiner-administered iOS-based battery of neuropsychological tests designed to measure neurocognitive functioning in children ages 5–11. This study documented Multivariate Base Rates (prevalence of low scores when multiple test scores are considered simultaneously) in the ImPACT® Pediatric standardization sample (N = 892). In the total sample, it was common for children to obtain at least one low factor score using the 25th percentile [T 43; base rate (BR) = 54.2%], 16th percentile (T40, BR = 38.1%), and the 10th percentile (T37, BR = 31.1%). However, it was uncommon for children to obtain two (or more) low factor scores using any of the above-listed cutoff score.
