Attachment and eating: A meta-analytic review of the relevance of attachment for unhealthy and healthy eating behaviors in the general population

Exploring the reciprocal relationships between adolescents' perceptions of parental and peer attachment and disordered eating: A multiwave cross-lagged panel analysis

OBJECTIVE

This prospective study explored bidirectional associations between attachment quality towards mother, father, and peers and disordered eating among a large population-based sample of boys and girls in the transition from preadolescence to adolescence. Specifically, we examined whether insecure attachment relationships emerged as a risk factor for or as an outcome of disordered eating.

METHOD

A population-based sample of 904 adolescent girls and boys was assessed four times, at baseline (T1; M_age  = 10.8 years) and at 2-, 4-, and 6-year follow-up (T2, T3, and T4). Prospective data were analyzed using cross-lagged panel models for each attachment figure (i.e., mother, father, peers) in a multigroup design to compare genders.

RESULTS

Better attachment to the mother led to less pronounced disturbed eating in girls across the entire age range and in boys across two time periods. In girls, more pronounced disordered eating at T3 predicted worse attachment to the mother at T4 and better attachment to the father at T1 predicted less disturbed eating at T2. In boys, disordered eating at T1 predicted better attachment to the father at T2. Concerning peer attachment, better attachment at T1 predicted disordered eating at T2, in boys only. No other significant cross-lagged effects emerged.

DISCUSSION

These findings highlight the differential and gender-specific contribution of attachment figures to the development of disordered eating in adolescence. Programs aimed at improving communication and trust in the relationship with parents might be promising in the prevention of disordered eating and the subsequent deterioration of parent-child attachment relationships.

Prospective Study of Attachment as a Predictor of Binge Eating, Emotional Eating and Weight Loss Two Years after Bariatric Surgery

Bariatric surgery remains the most effective treatment for severe obesity, though post-surgical outcomes are variable with respect to long-term weight loss and eating-related psychopathology. Attachment style is an important variable affecting eating psychopathology among individuals with obesity. To date, studies examining eating psychopathology and attachment style in bariatric surgery populations have been limited to pre-surgery samples and cross-sectional study design. The current prospective study sought to determine whether attachment insecurity is associated with binge eating, emotional eating, and weight loss outcomes at 2-years post-surgery. Patients (n = 108) completed questionnaires on attachment style (ECR-16), binge eating (BES), emotional eating (EES), depression (PHQ-9), and anxiety (GAD-7). Multivariate linear regression analyses were conducted to examine the association between attachment insecurity and 2-years post-surgery disordered eating and percent total weight loss. Female gender was found to be a significant predictor of binge eating (p = 0.007) and emotional eating (p = 0.023) at 2-years post-surgery. Avoidant attachment (p = 0.009) was also found to be a significant predictor of binge eating at 2-years post-surgery. To our knowledge, this study is the first to explore attachment style as a predictor of long-term post-operative eating pathology and weight outcomes in bariatric surgery patients.

Disorganized attachment predicts body mass index via uncontrolled eating

BACKGROUND/OBJECTIVES

Previous research has demonstrated relationships between attachment orientations (expectations of ourselves and others in interpersonal relationships), eating behaviours and obesity. However, such research has been limited to investigations of 'organised' forms of attachment orientations (reflecting coherent and predictable patterns of behaviour). Theoretically, aberrant eating behaviours and body mass index, should also be related to 'disorganized attachment.'

SUBJECTS

Here we test these relationships for the first time in a general population. Secondary data analyses of a pre-existing dataset were conducted (N = 537).

METHODS USED

Questionnaire measures of organised (avoidant and anxious) and disorganized attachment were included alongside eating behaviour measures (emotional eating, uncontrolled eating and cognitive restraint) and body mass index (BMI).

RESULTS

Parallel multiple mediation analysis (PROCESS) showed that uncontrolled eating (but not emotional eating or cognitive restraint) significantly mediated a relationship between disorganized attachment and body mass index (significant indirect relationship; LLCI = 0.02 ULCI = 0.16) when both attachment anxiety and avoidance were included as covariates.

CONCLUSIONS

We suggest that the mechanism underpinning this indirect relationship is a form of maladaptive affect regulation, but that the behavioural motivators differ from those observed in anxiously attached individuals. Rather than eating being a premeditated strategy used by individuals high in disorganized attachment to manage emotion, opportunities to eat are simply taken as they present themselves. Professionals engaged in addressing eating problems and weight management should consider attachment orientations in their patient assessments and be mindful that attachment disorganized individuals are especially likely to engage in uncontrolled eating behaviours that are associated with a higher BMI.

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.

The vulnerability to interpersonal stress in eating disorders: The role of insecure attachment in the emotional and cortisol responses to the trier social stress test

BACKGROUND

Vulnerability to interpersonal stress is an important risk factor for Eating Disorders (EDs). Adult insecure attachment involves different emotional, biological and behavioural strategies to cope with social stressors. However, although attachment has proved to play a pivotal role in EDs, no study has yet explored the effects of attachment on the emotional and hypothalamic-pituitary-adrenal (HPA) axis responses to a psychosocial stressor in EDs.

METHODS

Fifty-two ED women (29 with anorexia nervosa, 23 with bulimia nervosa) underwent the Trier Social Stress Test (TSST). Their emotional response was measured by means of the State-Trait Anxiety Inventory state scale while saliva samples were collected to measure cortisol secretion.

RESULTS

According to the Experience in Close Relationship questionnaire scores, 21 ED patients had high attachment anxiety and 31 low attachment anxiety, whilst 34 had high attachment avoidance and 18 low attachment avoidance. Patients with high attachment anxiety or avoidance displayed heightened TSST-induced cortisol secretion and anxiety feelings, in comparison to those with low insecure attachment scores. Anxiety perception was associated with cortisol recovery after the test exposure but not with the HPA axis reactivity in insecure attached patients.

CONCLUSIONS

The present findings corroborate the hypothesis that attachment modulates the biological and emotional reactivities to an acute social threat in ED patients. The role of these attachment-mediated changes in vulnerability to interpersonal stress in EDs needs to be clarified in future studies.

Recent Research and Personalized Treatment of Anorexia Nervosa

The aim of this article is to consider how neuropsychological understanding and new research can be used to develop a more individualized and personalized approach in the management of this serious illness.

Household Chaos, Maternal Emotional Responsiveness, and Child Eating Behavior: A Moderation Analysis

OBJECTIVE

To address calls for a resilience-informed approach to understand the cause and prevention of childhood obesity, the current study aims to investigate the independent and interactive associations between household chaos, maternal emotional responsiveness, and eating behavior in early childhood.

METHOD

A sample of (n = 108) families of 18- to 24-month-olds completed self-report surveys and consented to home visits as part of the larger STRONG Kids 2 (N = 468) study. Videotapes of family mealtimes were collected during home visits and coded for observed maternal emotional responsiveness. Mothers completed questionnaires assessing maternal emotional responsiveness, household chaos, and child eating behaviors. Moderation analyses assessed independent and interactive effects of chaos and emotional responsiveness on child appetite self-regulation.

RESULTS

In moderation analyses controlling for demographic covariates, higher levels of chaos were associated with more emotional overeating and with more food responsiveness, but only among children of mothers observed engaging in low levels of responsiveness at mealtimes. There was no association between chaos and eating behavior among children of mothers observed engaging in high levels of emotional responsiveness at mealtimes. There was also no independent or interactive association between chaos and child eating behaviors characterized by food avoidance.

CONCLUSION

Preliminary evidence suggests that maternal emotional responsiveness at mealtimes may attenuate the deleterious effects of chaos on child overeating and food responsiveness. Future research should prioritize using longitudinal designs, developing observational assessments of early childhood eating behaviors, and understanding these processes among families exposed to greater socioeconomic adversity.
