An investigation of the mediating role of personality and family functioning in the association between attachment styles and eating disorder status

Parent-child age gaps in patients with anorexia and bulimia nervosa and their associations with family dysfunction

BACKGROUND

Family factors are linked to the development of anorexia nervosa (AN) and bulimia nervosa (BN). However, due to a lack of direct comparison, it is still unknown whether the two entities of eating disorders differ with respect to the age gaps between parents and their affected children.

METHODS

In a cohort of 568 patients from the FamFINED study (FAMily Factors INvolved in Eating Disorders) diagnosed with eating disorders, we assessed the relationships between the parent-child age differences and family dysfunction, as determined by means of the General Family Questionnaire ("Allgemeiner Familienbogen" [FBA]).

RESULTS

Data showed that the age difference between the mother and the affected child was significantly higher in AN compared to BN patients (29.3 ± 5.3 vs. 28.3 ± 5.1 years, p = 0.017). Logistic regression confirmed that, also in adjusted models, the mother-child age difference significantly differed between the diagnoses of the two eating disorders (exp (B) = 0.918, 95% confidence interval 0.87-0.97, p = 0.004). However, the paternal age difference did not reach a statistical significance in the comparison between the two groups (p = 0.071).

CONCLUSIONS

The two entities of eating disorders differed significantly with respect to the age difference between the mother and the affected subject. The maternal age difference was higher in anorectic than in bulimic patients from the same study population. Further research is required to identify the psychophysiological mechanisms underlying these age-dependent effects.

Attachment, motivational systems and anorexia nervosa: A systematic review and proposed framework for eating disorders

INTRODUCTION

There is a direct association between patients with insecure attachment style (IAS), behavioural inhibition (BIS) and behavioural activation (BAS) motivational systems, and anorexia nervosa (AN). However, the possible direct relationships between these three variables have not been studied.

OBJECTIVE

The main objective of this study is to analyse the relationship between these variables and propose a framework for analysing and understanding these relationships.

METHODOLOGY

A systematic review was carried out following the Preferred Reporting Items for Systematic Reviews and Meta-Analysis (PRISMA) guidelines, searching the following terms: 'anorexia', 'attachment' and those related to motivational systems. The final search was limited to publications in English dated between 2014-2022 for 'anorexia and attachment' and 2010-2022 for 'anorexia and BIS/BAS'.

RESULTS

Of the 587 articles retrieved, 30 were included in this study for the textual data analysis of the relationship between anorexia and attachment (17), anorexia and motivational systems (10) and anorexia, attachment and motivational systems (3). An association between avoidant IAS, AN and hypersensitivity to punishment of the BIS was observed in the analysis. A relationship was also observed with hyperreinforcement sensitivity of the BAS. After reviewing the articles, a possible relationship between the three factors, along with other mediating factors, was found.

DISCUSSION

AN is directly related to the avoidant IAS and to BIS. Similarly, bulimia nervosa (BN) was directly related with anxious IAS and BAS. However, contradictions were found in the BN-BAS relationship. This study proposes a framework for analysing and understanding these relationships.

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.

Mechanisms by which adverse childhood experiences, other traumas and PTSD influence the health and well-being of individuals with eating disorders throughout the life span

BACKGROUND

Multiple published sources from around the world have confirmed an association between an array of adverse childhood experiences (ACEs) and other traumatic events with eating disorders (EDs) and related adverse outcomes, including higher morbidity and mortality.

METHODS

In keeping with this Special Issue's goals, this narrative review focuses on the ACEs pyramid and its purported mechanisms through which child maltreatment and other forms of violence toward human beings influence the health and well-being of individuals who develop EDs throughout the life span. Relevant literature on posttraumatic stress disorder (PTSD) is highlighted when applicable.

RESULTS

At every level of the pyramid, it is shown that EDs interact with each of these proclaimed escalating mechanisms in a bidirectional manner that contributes to the predisposition, precipitation and perpetuation of EDs and related medical and psychiatric comorbidities, which then predispose to early death. The levels and their interactions that are discussed include the contribution of generational embodiment (genetics) and historical trauma (epigenetics), social conditions and local context, the ACEs and other traumas themselves, the resultant disrupted neurodevelopment, subsequent social, emotional and cognitive impairment, the adoption of health risk behaviors, and the development of disease, disability and social problems, all resulting in premature mortality by means of fatal complications and/or suicide.

CONCLUSIONS

The implications of these cascading, evolving, and intertwined perspectives have important implications for the assessment and treatment of EDs using trauma-informed care and trauma-focused integrated treatment approaches. This overview offers multiple opportunities at every level for the palliation and prevention of EDs and other associated trauma-related conditions, including PTSD.

The Mediator Effect of Personality on the Relationship Between Symptomatic Impairment and Treatment Outcome in Eating Disorders

Features of personality disorders (PDs) have been found to explain meaningful variance in the onset, maintenance, and symptomatic presentation of eating disorders (EDs), and a co-occurent personality pathology is commonly associated with poorer response to ED treatment. The "pathoplasty model" of the relationship between personality and EDs implies that, once both conditions are established, they are likely to interact in ways that modify therapy outcome; however, to date, no studies have explored overall personality functioning, and especially PD clusters, as a mediator of treatment outcome. The present study aimed at conjointly exploring the associations between personality functioning and PDs, respectively, with pre-treatment ED symptomatic impairment and therapy outcome; and the mediating role of personality variables. At treatment onset, a sample of 107 women with ED problems were evaluated using both the Structured Clinical Interview for DSM-5 (SCID-5-CV) and the Shedler-Westen Assessment Procedure-200 (SWAP-200)-a clinician-rated procedure to dimensionally assess personality. Participants were also asked to complete self-report questionnaires on overall ED symptomatology, symptoms of binge eating and purging behaviors, and therapy outcome. The findings showed that, over and above the categorical ED diagnosis, the SWAP-200 healthy personality functioning score mediated the relationship between baseline ED symptom severity and therapy outcome, as well as the association between baseline bulimic symptoms and treatment outcome; furthermore, SWAP-200 Cluster B PD scores mediated the link between baseline binge eating and purging symptoms and therapy outcome, whereas scores in Clusters A and C showed no significant effects. The findings suggest that personality-based outcome research may improve treatment effectiveness in this difficult-to-treat population.

Paternity and Parenting in the Context of Eating Disorders: An Integrative Literature Review

Abstract Family relationships seem to have relevant contribution to the etiopathogenesis of Eating Disorders (EDs). This study aimed to analyze the scientific production about the paternity and parenting experiences of fathers whose daughters developed EDs. The literature review was conducted through the databases LILACS, PubMed, PsycINFO, Web of Science and EMBASE, in the period from 1999 to 2019. From the 878 retrieved papers, 23 were selected for the analysis. The results show that paternity and parenting experiences are influenced by father’s personality traits. The dominant representation is of an affectionless and not empathetic father, as well as punitive and insensitive to the daughter’s emotional needs. Knowing the paternal experiences is central to subside sensible care to both, daughters’ and fathers’ demands.

Comparing Cognitive Behavioral Therapy and Systemic Therapy for Social Anxiety Disorder: Randomized Controlled Pilot Trial (SOPHO-CBT/ST)

This randomized controlled trial (RCT) aimed to pilot the newly developed manualized and monitored systemic therapy (ST) for social anxiety disorder (SAD), as compared to manualized and monitored cognitive behavioral therapy (CBT). We conducted a prospective multicenter, assessor-blind pilot RCT on 38 outpatients (ICD F40.1; Structured Clinical Interview for DSM (SCID); Liebowitz Social Anxiety Scale, LSAS-SR >30). The primary outcome was level of social anxiety (LSAS-SR) at the end of treatment. A total of 252 persons were screened, and 38 patients were randomized and started therapy (CBT: 20 patients; ST: 18 patients; age: M = 36 years, SD = 14). Within-group, simple-effect intent-to-treat analyses (ITT) showed significant reduction in LSAS-SR (CBT:d = 1.04; ST:d = 1.67), while ITT mixed-design ANOVA demonstrated the advantage of ST (d = 0.81). Per-protocol analyses supported these results. Remission based on reliable change indices also demonstrated significant difference (LSAS-SR: 15% in CBT; 39% in ST;h: 0.550), supported by blind diagnosticians' ratings of those who completed therapy (SCID; 45% in CBT, 78% in ST,p = .083). No adverse events were reported. CBT and ST both reduced social anxiety, supporting patient improvement with the newly developed ST for SAD; this has yet to be verified in a subsequent confirmatory RCT.

Establishment of a multifamily therapy (MFT) service for young adults with a severe eating disorder - experience from 11 MFT groups, and from designing and implementing the model

BACKGROUND

Eating disorders are serious illnesses leading to a substantially lowered quality of life not only for the patient but also for their family. They are difficult to treat, and many patients fail to complete their treatment. At the Regional Centre for Eating Disorders (RESSP) at Nordland Hospital in Bodø, in the north of Norway, it was apparent that many young adult patients maintained an active, ongoing relationship with their family of origin, and that parents and others were often highly involved in their life and illness. It was therefore desirable to develop a treatment model involving family members; specifically a multifamily therapy (MFT) group programme.

METHODS

The aim was to establish an MFT service at RESSP for young adult patients suffering from severe eating disorders. This involved, (1) work preparatory to the establishment of the new service, (2) the development and implementation of a suitable MFT model, and (3) sharing the skills and knowledge gained from our experiences to other professionals in the field, and in other settings. This work of development and change can be understood as a process of innovation and is here described within the framework of implementation theory. The work took place in a clinically naturalistic context at the centre.

RESULTS

The MFT model description is based on experience during its development as well as its final form. The stages of this development process and of the changes made in order to establish the new service are described, together with its core components. To date, 68 patients and 198 family members have participated. Dropout rate has been 7.4% and the majority of patients have continued in treatment after completion of the MFT groups. BMI measurements show a significant weight-gain for those with an underweight at start. 32 other professionals have been trained in the model, and a similar service started in 3 other units.

CONCLUSION

The new model has been welcomed by patients and families alike. The MFT group programme has had a strikingly low dropout rate and a majority of patients have continued in treatment. BMI measurements show a significant weight-gain for those being underweight at start. Other therapists have been trained in the model, and similar services set up elsewhere. In order to document and increase the usefulness of the MFT treatment, a research project has been initiated to evaluate experience and outcomes both quantitatively and qualitatively.

An Aristotelian view of therapists' practice in multifamily therapy for young adults with severe eating disorders

BACKGROUND

Eating disorders are serious conditions which also impact the families of adult patients. There are few qualitative studies of multifamily therapy with adults with severe eating disorders and none concerning the practice of therapists in multifamily therapy.

OBJECTIVES

The aim of the study is to explore therapists' practice in multifamily therapy.

RESEARCH DESIGN AND PARTICIPANTS

A grounded theory approach was chosen. Data were collected through participant observation in two multifamily therapy groups and qualitative interviews with the therapists in those groups.

ETHICAL CONSIDERATIONS

The study conforms to the principles outlined in the Declaration of Helsinki. All participants in the multifamily therapy groups received information about the research project and signed consent forms. The data are treated confidentially and anonymised.

FINDINGS

The core category was identified as 'having many strings to one's bow', consisting of three subcategories: 'planning and readjusting', 'developing as therapist and team' and 'regulating the temperature of the group'. This article discusses the empirical findings in the frame of Aristotelian virtue ethics.

Assessment of Family Functioning and Eating Disorders - The Mediating Role of Self-Esteem

The aim of the study was to measure whether people at increased risk for eating disorders (EDs) and people without an increased risk of EDs differ from each other in the assessment of family functioning (FF) and self-esteem (SE) dimensions. Moreover, the correlations between FF, EDs, and SE were verified, looking for the mediating role of SE in the context of the FF and EDs. The research was conducted on the group of 160 people aged from 18 to 47 years, including 74 people at increased risk for EDs. We used: The Family APGAR (Adaptability, Partnership, Growth, Affection, and Resolve); The SCOFF Questionnaire; The Multidimensional Self-Esteem Inventory, MSEI. Analyses indicate that the compared groups differ significantly in terms of EDs, assessment of FF, and all components of SE, in such a way that people without an increased risk of EDs are characterized by a more positive assessment of FF and higher SE in all its dimensions. All SE dimensions, except defensive high SE, are mediators in the relationship of FF with EDs. In therapeutic interactions, it is worth focusing on the SE dimensions, as they are one of the mediation elements in the relationship between the assessment of FF and EDs.

Mediators linking insecure attachment to eating symptoms: A systematic review and meta-analysis

In the last two decades, the number of studies focused on the mediators connecting insecure attachment with Eating Disorders (EDs), at both clinical and sub-clinical level, has considerably increased. However, there has not been a systematic synthesis of this literature to date. To fill this gap, the current meta-analytic review aimed at identifying and quantifying the extent to which mediators contribute to the explanation of this relationship. The present study was registered with PROSPERO (CRD42017076807). A comprehensive search process in seven different electronic databases retrieved 24 studies that examined how insecure attachment leads to ED symptoms through mediation analysis. Standardized regression coefficients of the indirect and total paths of 21 mediation models were pooled. Studies were coded and ranked for quality. We found evidence to show that maladaptive emotion regulation and depressive symptoms had the highest effect size for mediation (mediation ratio [P_M] = 0.71). Further, body dissatisfaction, neuroticism, perfectionism, mindfulness and social comparison had significant, but moderate to low mediating effects (P_M = 0.21–0.58). The methodological quality of these studies was mostly low to moderate and potential areas for development were highlighted. Our findings support the direct targeting of these psychological constructs in prevention programs and treatment of EDs. Future investigations addressing the time sequence between the variables will provide valuable clues to untangle the prospective contribution of each variable on the development and maintenance of eating pathology.

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.

Anorexia nervosa and attachment

Introduction

Attachment is an innate programming whereby a child seeks for security. There is scientific and empirical evidence that insecure attachment is usual in eating disorder patients [1].

Objectives

To highlight the relevance of attachment between child and caregivers, as well as its significance in therapeutic approach.

Methods

A 17-year-old girl hospitalized after attending to emergency department due to fainting. BMI: 12.89. She reports restrictive behavior since age 11 that her mother regards as “child issues”. Divorced parents, she grew up with her mother, diagnosed of hypochondria, who mentions not understanding why she is not the one who is hospitalized.

Results

During hospitalization, she turned 18-years-old. Guardianship of her younger siblings was removed to her mother. She had a secure relationship with her 24-year-old sister, so she decided to move in with her. Later on, she had a positive progress, maintaining the gained weight and mood stability, although cognitive distortions persist.

Conclusions

Among developmental and maintaining factors of eating disorders, impaired attachment is becoming increasingly interesting. Even though the main goal of treatment is weight restoration, exploring attachment patterns can facilitate to achieve that aim. This clinical case emphasizes the importance of attachment in eating disorders among child and young adults.
