Disorder-specific attachment characteristics and experiences of childhood abuse and neglect in adolescents with anorexia nervosa and a major depressive episode

Two identical twin pairs discordant for longstanding anorexia nervosa and OSFED: lived experience accounts of eating disorder and recovery processes

Research into the risk of anorexia nervosa (AN) has examined twin pairs to further the understanding of the contributions of genetics, trait inheritance, and environmental factors to eating disorder (ED) development. Investigations of twin experiences of EDs have been biologically-based and have not considered the qualitative, phenomenological aspects of twin experiences. A gap in the literature exists regarding understanding of discordant twins with EDs. This research was developed in response, with the aim to deepen understanding of AN in discordant twins and to create novel ideas for further research and testing. The case studies presented in this article provide lived experience insights of two identical discordant twin pairs: one twin pair discordant for longstanding AN and one twin pair discordant for 'atypical' AN (the twin with AN has recovered). The perspectives and experiences of each co-twin (one with AN and one without) explore a number of factors that may have contributed to twin discordance in these cases, and how each twin has responded to the impact of AN in their lives. Through use of first-person accounts in case study presentation, this article centres social justice values of lived experience leadership and involvement in research. This article aims to extend current knowledge and understanding of EDs in discordant twins, particularly regarding risk for ED development, ED duration, diagnosis and treatment, and recovery processes.

Identifying and synthesizing components of perinatal mental health peer support - a systematic review

Background

Becoming a parent, while often perceived as a joyous event, can also be a vulnerable life transition, with approximately one in five mothers experiencing perinatal mental illness. Peer support is recommended for its preventive and therapeutic benefits. However, relevant program components of perinatal mental health peer support remain to be identified.

Objectives

This review aims to (1) identify peer support programs in perinatal mental health through existing reviews and to (2) synthesize the components of these programs.

Methods

A systematic literature review guided by PRISMA was conducted searching four databases, supplemented by hand searches. The Template for Intervention Description and Replication (TIDieR) checklist facilitated the systematic extraction and synthesis of program components.

Results

Eleven peer support programs were identified from three reviews, largely conducted in English-speaking countries. The identified reviews highlight the benefits of peer support in perinatal mental health. Key components of individual programs were contextual background, materials, provider training and support, delivery modes and locations, and evaluation. Sharing lived experience and providing flexible support were central to all programs.

Conclusion

Aspects of flexibility, authenticity and the challenges of program evaluation in peer support must be considered. Findings can now inform future planning and implementation efforts of peer support programs in periantal mental health.

Association between traumatic events with suicidality among adolescents: A large-scale cross-sectional study of 260,423 participants

Traumatic events have significant negative impacts throughout one's life. We aimed to comprehensively examine the early associations between traumatic events and suicidality among adolescents. In a cross-sectional sample of 260,423 adolescents in Deyang, China in September 2021, we assessed individual traumatic events, cumulative types, and patterns, alongside suicide risk scores and ideation, attempts, or plans. Linear and Poisson regression models adjusted for demographic confounders evaluated the association. Robust associations existed between interpersonal violence-related traumatic events and higher suicidality, with physical abuse demonstrating the strongest correlation. Moreover, suicide risk scores displayed a clear trend, indicating a progressively stronger association with suicidality as cumulative traumatic event types increased. Four distinct traumatic patterns emerged, including low traumas, high physical abuse, high death/serious injuries of a loved one, and multiple traumas, with the latter showing the strongest association with suicidality. Notably, the stratified analysis showed these associations were more pronounced in females, urban residents, only children, left-behind children, and those aged 13-15, while weaker in participants from families with intact parental relationships and middle socioeconomic status. Understanding the role of demographic factors and traumatic patterns in identifying at-risk youth can enable early detection and targeted interventions for suicide-related concerns.

Personality Disorders and Attachment Trauma in Adolescent Patients with Psychiatric Disorders

This study examined how personality disorders (PD) differ with respect to gender, attachment status and traumatic childhood experiences in adolescent psychiatric inpatients. In particular, we investigated attachment-related traumatic material underlying adolescent PD. Our sample consisted of 175 inpatient adolescents aged 14 to 18 years (77% female, Mage = 15.13, SD = 1.35; 23% male, Mage =14.85, SD = 1.41). Thirty-nine patients (22%) fulfilled the diagnostic criteria for a PD according to the SCID-II PD: 51% avoidant, 13% obsessive-compulsive, 13% antisocial, 19% borderline, 2% paranoid and 2% histrionic. In the total sample, eighty-three (47%) of our inpatients were classified with an unresolved attachment status using the Adult Attachment Projective Picture System (AAP). We did not find any significant gender differences for patients with and without a PD. Our results revealed a higher percentage of unresolved attachment status in patients with a PD. The in-depth analysis of the total sample showed that patients with a PD demonstrated more traumatic material in their attachment interviews indicating a greater severity of attachment trauma. Furthermore, patients with a PD reported higher scores on emotional and physical neglect. Intervention strategies targeting traumatic attachment-related themes might be useful to treat adolescents with PD.

Unresolved attachment and identity diffusion in adolescence

This study examined the severity of unresolved attachment underlying adolescent identity diffusion. Our sample consisted of 180 inpatient adolescents aged 14 to 18 years (77% female, M age = 15.13, SD = 1.35; 23% male, M age = 14.85, SD = 1.41) and 84 age-matched non-clinical adolescents (52% female, M age = 16.14, SD = 1.21; 48% males, M age = 15.98, SD = 1.07). We used the Adult Attachment Projective Picture System (AAP) interview to assess attachment representations and the Assessment of Identity Development in Adolescence (AIDA) questionnaire to evaluate the severity of identity diffusion. Our results demonstrate a higher amount of unresolved attachment and identity diffusion in the patient sample than in the control sample. Furthermore, patients with an unresolved attachment status scored higher on identity diffusion than those with no unresolved attachment pattern. Interestingly, this was not found in the control group. Furthermore, patients with a greater severity of unresolved attachment showed the highest maladaptive identity development scores. Psychotherapeutic interventions integrating attachment-related aspects might be useful to treat young people with identity diffusion.

Attachment Trauma Is Associated with White Matter Fiber Microstructural Alterations in Adolescents with Anorexia Nervosa before and after Exposure to Psychotherapeutic and Nutritional Treatment

In the present study, we explore the role of attachment for microstructural white matter (WM) changes in adolescents with anorexia nervosa (AN) before and after exposure to short-term and nutritional treatment. The case sample consisted of 22 female adolescent inpatients with AN (mean age: 15.2 ± 1.2 years) and the control sample were 18 gender-matched healthy adolescents (mean age: 16.8 ± 0.9 years). We performed a 3T MRI in the patient group during the acute state of AN and after weight restoration (duration: 2.6 ± 1 months) and compared the data to a healthy control group. To classify attachment patterns, we used the Adult Attachment Projective Picture System. In the patient sample, over 50% were classified with an attachment trauma/unresolved attachment status. Prior to treatment exposure, fractional anisotropy (FA) reductions and concordant mean diffusivity (MD) increases were evident in the fornix, the corpus callosum and WM regions of the thalamus, which normalized in the corpus callosum and the fornix post-therapy in the total patient sample (p < 0.002). In the acute state, patients with an attachment trauma demonstrated significant FA decreases compared to healthy controls, but no MD increases, in the corpus callosum and cingulum bilaterally, which remained decreased after therapy. Attachment patterns seem to be associated with region-specific changes of WM alterations in AN.

Attachment in individuals with eating disorders compared to community controls: A systematic review and meta-analysis

OBJECTIVE

Individuals with eating disorders are known to have higher rates of insecure attachment compared to community controls, but the factors underlying this finding are poorly understood. We conducted the first meta-analysis comparing attachment in eating disorder samples compared to community controls that included quality assessment, publication bias and moderation analysis.

METHOD

We pre-registered our meta-analysis (CRD42019146799) and followed PRISMA guidelines. We searched PsychINFO, Embase, Medline, CINAHL, and Scopus for publications. Attachment scores were extracted, and Cohen's d calculated for each study using a random effects model.

RESULTS

In total, 35 studies were included in the meta-analysis and six studies were summarized in a narrative review. Eating disorder samples showed higher rates of insecure attachment compared to community controls, with a large effect size, across measurement methods and different attachment dimensions. Blinding of assessors moderated effect sizes for attachment interview studies, but no other moderators were significant.

DISCUSSION

Risk of insecure attachment is elevated in individuals with eating disorders, albeit heterogeneity is high and largely unexplained. Clinicians may need to take this into account in their work, particularly given the association between attachment insecurity and challenges to therapeutic alliance. Future studies comparing eating disorder samples with community samples should control for general psychopathology.

PUBLIC SIGNIFICANCE

Attachment is a broad concept referring to a person's thoughts, feelings and behaviors in relation to close others. This systematic review and meta-analysis found that individuals with eating disorders are lower in attachment security than community controls, regardless of attachment construct or measurement approach. Attachment may be relevant in influencing eating disorder recovery, the development of therapeutic alliance, and potentially clinical outcomes, although more research is needed.

Novel ketamine and zinc treatment for anorexia nervosa and the potential beneficial interactions with the gut microbiome

Anorexia nervosa (AN) is a severe illness with diverse aetiological and maintaining contributors including neurobiological, metabolic, psychological, and social determining factors. In addition to nutritional recovery, multiple psychological and pharmacological therapies and brain-based stimulations have been explored; however, existing treatments have limited efficacy. This paper outlines a neurobiological model of glutamatergic and γ-aminobutyric acid (GABA)-ergic dysfunction, exacerbated by chronic gut microbiome dysbiosis and zinc depletion at a brain and gut level. The gut microbiome is established early in development, and early exposure to stress and adversity contribute to gut microbial disturbance in AN, early dysregulation to glutamatergic and GABAergic networks, interoceptive impairment, and inhibited caloric harvest from food (e.g., zinc malabsorption, competition for zinc ions between gut bacteria and host). Zinc is a key part of glutamatergic and GABAergic networks, and also affects leptin and gut microbial function; systems dysregulated in AN. Low doses of ketamine in conjunction with zinc, could provide an efficacious combination to act on NMDA receptors and normalise glutamatergic, GABAergic and gut function in AN.

Identifying Risk and Resilience Factors in the Intergenerational Cycle of Maltreatment: Results From the TRANS-GEN Study Investigating the Effects of Maternal Attachment and Social Support on Child Attachment and Cardiovascular Stress Physiology

Introduction

Childhood maltreatment (CM) is a developmental risk factor and can negatively influence later psychological functioning, health, and development in the next generation. A comprehensive understanding of the biopsychosocial underpinnings of CM transmission would allow to identify protective factors that could disrupt the intergenerational CM risk cycle. This study examined the consequences of maternal CM and the effects of psychosocial and biological resilience factors on child attachment and stress-regulatory development using a prospective trans-disciplinary approach.

Methods

Mother-child dyads (N = 158) participated shortly after parturition (t 0), after 3 months (t 1), and 12 months later (t 2). Mothers' CM experiences were assessed at t 0, attachment representation at t 1 and psychosocial risk and social support were assessed at t 1 and t 2. At t 2, dyads participated in the Strange Situation Procedure (SSP). Children's attachmen status were classified as organized vs. disorganized, including their level of disorganized behavior, and heart rate (HR) and respiratory sinus arrhythmia (RSA) were recorded as stress response measures of the autonomic nervous system. Maternal caregiving during SSP was assessed using the AMBIANCE scale. Child's single nucleotide polymorphisms rs2254298 within the oxytocin receptor (OXTR) and rs2740210 of the oxytocin gene (OXT) were genotyped using DNA isolated from cord blood.

Results

Maternal CM experiences (CM+) were significantly associated with an unresolved attachment status, higher perceived stress and more psychological symptoms. These negative effects of CM were attenuated by social support. As expected, maternal unresolved attachment and child disorganized attachment were significantly associated. Maternal caregiving did not mediate the relationship between maternal and child attachment but influenced children's HR and RSA response and disorganized behavior. Moreover, the rs2254298 genotype of the OXTR gene moderated the stress response of children from mothers with CM. Children carrying the rs2740210 risk allele of the OXT gene showed more disorganized behavior independent from maternal CM experiences.

Conclusion

We replicated and extended existing CM and attachment models by co-examining maternal attachment, social support, and child genetic susceptibility on child attachment and cardiovascular stress regulation. The findings contribute to an extended understanding of risk and resilience factors and enable professionals to target adequate services to parents and children at risk.

Attachment status is associated with grey matter recovery in adolescent anorexia nervosa: Findings from a longitudinal study

The aim of the present study was to investigate whether grey matter (GM) reductions in acute anorexia nervosa (AN) are (i) valid for adolescents (age 14-18 years), (ii) reversible following short-term psychotherapeutic and nutritional therapy and (iii) depend on psychological components like attachment trauma. 3T MRI including a high-resolution T1 MPRAGE was performed in 22 female adolescents in the acute state of AN (age: 15.2 ± 1.2 years) and after weight restoration (duration: 2.6 ± 1 months, n = 18) and compared with 18 gender-matched healthy controls. The Adult Attachment Projective Picture System was used to classify resolved and unresolved attachment patterns. GM decreases were localized in extensive cortical areas including the insula, prefrontal and cingulate cortices as well as subcortical regions during acute AN, which partially increased after therapy with a relative sparing of the hippocampus and parahippocampal gyrus. The resolved group showed more GM recovery in regions of the left hippocampus and parahippocampal gyrus, bilateral cerebellar regions, right precuneus and adjacent cingulate cortices relative to the unresolved pattern. Structural anomalies in adolescent AN that recovered after treatment may be primarily the consequence of malnutrition, whereas several regions did not display significant recovery. Attachment status seems to influence region-specific GM recovery.

Psychological characteristics and childhood adversity of adolescents with atypical anorexia nervosa versus anorexia nervosa

The assessment and diagnosis of atypical anorexia nervosa (AAN) is an ongoing challenge for clinicians. This study aims to examine psychological morbidity and exposure to childhood adversity in adolescents with AAN compared to adolescents with anorexia nervosa, restricting type (AN-R). This registry-based study compared 42 adolescents with AAN to 79 adolescents with AN-R on a variety of psychosocial measures at the time of presentation to a specialized eating disorder program. In contrast to AN-R, adolescents with AAN had more severe drive for thinness (p =.011), body dissatisfaction (p =.038), and lower quality of life (p =.047), but had better global functioning (p =.032). Adolescents who had high Adverse Childhood Experiences (ACE) Questionnaire scores (ACE score ≥ 4) had over 5 times higher odds of having AAN than those who did not have high ACE scores (p =.008). There was no significant difference between groups on measures of low self-esteem and non-accidental self-injury. Adolescents with AAN presented with similar or more severe psychosocial distress compared to their peers with AN-R across a majority of the measures. The findings highlight the need to address trauma, body-related difficulties, and quality of life in the assessment and treatment of adolescents with AAN.

Non-suicidal self-injury and attachment trauma in adolescent inpatients with psychiatric disorders

This study examined how non-suicidal self-injury disorder (NSSID) differs with respect to mental disorders, gender and attachment status in adolescent psychiatric patients. In particular, we analyzed attachment-related traumatic material underlying adolescent NSSID. Our sample consisted of 137 in-patient adolescents aged 12 to 18 years (73% female, M_age = 15.09, SD = 1.44; 27% male, M_age = 14.65, SD = 1.53). Forty-four patients (32.1%) fulfilled the diagnostic criteria for NSSID according to the DSM-5 and ninety-three patients (67.9%) did not meet diagnostic criteria for NSSID. Our results revealed a higher prevalence of NSSID in female patients and in patients with mood disorders. In the total sample, 52% of our in-patients were classified with an unresolved attachment status. The diagnostic subgroup analysis demonstrated a higher percentage of unresolved attachment status only in patients with eating disorders and NSSID. However, our in-depth analysis of the total sample revealed that patients with NSSID demonstrated more traumatic material in their attachment interviews indicating a greater severity of attachment trauma. In particular the theme of helplessness in interpersonal conflicts left them in a state of attachment dysregulation. Intervention strategies targeting traumatic attachment-related themes might be useful to reduce the number of adolescents engaging in NSSI.

Unresolved Attachment Mediates the Relationship Between Childhood Trauma and Impaired Personality Functioning in Adolescence

The present study investigates the mediating effect of attachment trauma on the relationship between childhood maltreatment and personality functioning in 199 adolescents (12-18 years) using a novel approach of an in-depth analysis of attachment-related traumatic contents during an attachment interview (AAP). Our findings demonstrate that adolescents with a high amount of traumatic attachment-related material show a lower resilience when facing traumatic childhood experiences, resulting in a greater severity of personality dysfunction. In particular, the associations between emotional abuse and neglect and the domains of identity, empathy, self-direction, and intimacy were mediated by the severity of attachment trauma. These results advance our understanding of the different nuances of attachment-related traumatic material and how they might shape personality structure in an adolescent age group.

Exploring the Link Between Emotional Child Abuse and Anorexia Nervosa: A Psychopathological Correlation

Eating disorders (ED) are well known psychiatric disorders associated with dysregulated eating behaviors and related thoughts and emotions. Common eating disorders are bulimia nervosa (BN), anorexia nervosa (AN), and binge eating disorders (BED). There is an active link between child abuse and eating disorders, emotional child abuse being the important subtype of CA and has a strong comorbid psychopathological relationship with EDs, including AN. The PubMed database was searched for the related articles about child abuse, including emotional childhood maltreatment and their psychopathology associated with EDs, especially AN. No filters were used for the date of publication and article types. Childhood abuse, including physical, sexual, and emotional maltreatment, has an active link with psychopathology associated with dysregulated eating behaviors. However, emotional childhood maltreatment including emotional abuse, neglect, and/or exposure to intimate partner violence (IPV) has been least studied, but studies have shown a strong relationship with the symptoms of anorexia nervosa such as weight concern, negative self-image, and maladaptive emotional response. Emotional dysregulation is the crucial psychopathological factor involved in mediating the effects of emotional childhood maltreatment and symptoms of anorexia nervosa and is strongly associated with long-term morbidity in patients with AN. Conducting more clinical studies in the future would help explore the temporal causation, and this association may help the practitioners to develop new diagnostic and therapeutic strategies in the management of AN.

The relationship between childhood abuse and depression in a sample of Chinese people who use methamphetamine

Background/Objective

Previous studies have shown that childhood abuse is associated with symptoms of depression. This study aims to examine the prevalence of childhood abuse or neglect and its correlation with depression among a sample of Chinese people who use methamphetamine.

Method

People who use methamphetamine (MA) (N = 1,173) were recruited from government-operated drug rehabilitation centres in Anhui province, China. Participants were assessed using the short form of Childhood Trauma Questionnaire and the Beck Depression Inventory-II for childhood abuse or neglect and depression symptoms.

Results

A total of 44.6% of people who use MA reported moderate/severe childhood abuse or neglect, and 56.9% of this sample were diagnosed with depression. Emotional abuse, sexual abuse, emotional neglect and physical neglect were revealed to increase the risk of depression. Multivariable regression analyses showed that depression scores were significantly predicted by gender, duration of drug use, sexual abuse and emotional neglect (model R² = .08, p < .001). The interaction between emotional neglect and duration of drug use on the depression was statistically significant.

Conclusions

These analyses indicate that sexual abuse and emotional neglect increase the severity of depression in individuals who use MA in drug rehabilitation centres of China.

Disorder-specific attachment characteristics and experiences of childhood abuse and neglect in adolescents with anorexia nervosa and a major depressive episode

For the first time, the present study investigates disorder‐specific attachment characteristics and childhood trauma in adolescent inpatients with anorexia nervosa (n = 30, girls/boys: 28/2, age: M = 14.84, SD = 1.20), a major depressive episode (n = 30, girls/boys: 27/3, age: M = 15.14, SD = 1.50), and controls (n = 60, girls/boys: 44/16, age: M = 16.10, SD = 1.20). We used the Structured Clinical Interview to diagnose Axis I disorders, the Adult Attachment Projective Picture System to classify attachment representations, and the Childhood Trauma Questionnaire to assess child maltreatment. Our findings demonstrate an overrepresentation of the unresolved attachment status in the patient samples. A one‐way analysis of variance succeeded by Bonferroni post hoc tests indicated that adolescents with anorexia nervosa show more isolation and dissolution of boundaries between life and death when confronted with situations of solitude. Although they report moderate to severe levels of traumatic childhood experiences, they tend to minimize those. Adolescents with a major depressive episode report higher levels of emotional abuse and neglect in their childhood, leaving them in a state of failed protection and danger during attachment distress. Integrating these attachment‐related characteristics into specific psychotherapeutic interventions might be associated with a better outcome in that age group.
