Eating Disorder Symptomatology and Identity Formation in Adolescence: A Cross-Lagged Longitudinal Approach

Identity Functioning in Patients with an Eating Disorder: Developmental Trajectories throughout Treatment

Increasing research has indicated a strong association between identity functioning and eating disorder (ED) symptomatology. However, a detailed investigation of identity throughout ED treatment is lacking. The present longitudinal study examined identity in inpatients with an ED and explored its simultaneous change with ED symptomatology throughout treatment. A total of 225 female patients completed questionnaires at admission. From these 225 patients participating at admission (Wave 1), 110 also participated in at least one additional measurement wave, with 43.64% (n = 48) participating at admission and during treatment, 16.36% (n = 18) participating at admission and at discharge, and 40% (n = 44) participating at admission, during treatment and at discharge. Questionnaires on identity synthesis, identity confusion, identity processes, and ED symptomatology were completed. Latent growth curve modeling was used to address the research questions. Throughout treatment, a decrease in identity confusion and an increase in identity synthesis and adaptive identity processes were found. Accordingly, increases in identity synthesis and identification with commitment were related to general decreases in the drive for thinness and body dissatisfaction. Similarly, such decreases in ED symptoms were related to general decreases in identity confusion and ruminative exploration. The present study points to an increase in identity functioning throughout treatment, and longitudinal associations between identity functioning and ED symptomatology were found. Helping patients to decrease their ruminative exploration and to increase their identification with previously made life commitments and treating body/weight concerns could both be helpful in ED treatment.

Effects of the COVID-19 pandemic on youth mental health: a cross-sectional study on eating disorder patients and their unaffected siblings

BACKGROUND

Adolescence has emerged as a particularly vulnerable phase during the COVID-19 pandemic, with eating disorders (EDs) representing a prominent psychopathological challenge linked to the restrictions imposed by the pandemic. Emerging evidence suggests that not only individuals with EDs but also their healthy siblings (HS) may experience unique psychological effects in this context. However, the existing literature on this topic remains limited. This study seeks to examine and compare the effects of the pandemic on adolescents and adults, with a specific focus on the impact of containment measures, disruptions in daily routines, and alterations in life trajectories, for both individuals with EDs and their HS.

METHODS

We enrolled 273 individuals, including those diagnosed with EDs and their HS. Among the participants, 120 were under the age of 19. Multiple self-report questionnaires were administered to assess the psychological impact of 1 year of the COVID-19 pandemic. These assessments covered a range of psychological constructs, including posttraumatic symptoms, general psychopathology, and eating-related concerns.

RESULTS

Notably, adolescent patients with EDs demonstrated the highest psychopathological scores within our sample. They were the sole subgroup to surpass clinical cutoffs, exhibiting more pronounced issues concerning eating-related concerns and general psychological well-being. Our findings also shed light on the unique experiences of HS during the pandemic.

CONCLUSION

Our findings highlight the specific psychological burden endured by adolescents with EDs throughout the COVID-19 pandemic, emphasizing the vulnerability of this demographic. Moreover, the experiences of HS, often overlooked in the literature, warrant increased attention in future health programs and interventions.

Inhabiting the body: Exploring the link between embodiment and identity in community adolescents

The intricate relationship between the body and identity has been highlighted in previous studies. However, a holistic approach to the body that focuses on embodiment is lacking in research examining body - identity linkages. The current study (N = 917 adolescents; 58% female; Mage = 16.17, range = 14-19 years) examined the psychometric properties of a Dutch translation of the Experience of Embodiment Scale (EES) and explored the link between embodiment and personal identity. First, confirmatory factor analysis revealed a second-order factor structure for the EES and adequate reliability coefficients were obtained. Metric invariance across gender was demonstrated for the first- and second-order factors. Second, path analysis demonstrated that experiencing embodiment was positively associated with adaptive identity work. Third, five identity statuses emerged using cluster analysis. Adolescents in statuses reflecting less adaptive identity functioning displayed lower levels of embodiment. The EES shows promising indications of reliability and factor structure for assessing adolescents' Experience of Embodiment, and the present study demonstrates that embodiment is meaningfully related to identity functioning. These findings support the call for the adoption of a positive psychology framework within this research field, with attention given to more broadly defined body-related concepts such as embodiment.

Reduction of adverse events in a psychiatric inpatient eating disorder unit during the COVID-19 pandemic

TOPIC

Globally, the COVID-19 pandemic had impacted the health care delivery including inpatient psychiatric facilities. Within psychiatric settings, life of inpatients was profoundly altered.

PURPOSE

This paper aimed to understand if pandemic-related changes within an inpatient Eating Disorder Unit in a specialized psychiatric hospital in Ontario, Canada impacted incidence of aggression and use of coercive methods among adolescents.

SOURCE USED

An exploratory study design was used to examine incidence of aggression, self-harm, code whites, staff assist, restraints and seclusion, and nasogastric feeding (NGF) among adolescents with eating disorders before and after the modified service delivery within the inpatient unit. Descriptive analyses were conducted.

RESULTS

Analyses revealed a complete reduction in episodes of self-harm, aggression, staff assists, use of restraint and seclusion as well as an 80.14% reduction on average use of NGF.

CONCLUSION

Authors speculate that the change in environment and program delivery method, peer influence, and shift in power relations between patient and staff may have resulted in improved experiences. This report provides insights to adopt a recovery-oriented service delivery for adolescents with eating disorders in inpatient settings.

Psychometric Properties of the Dutch Version of the Eating Competence Satter Inventory (ecSI 2.0TM) in Community Adolescents

Eating competence can help adolescents navigate their food choices and attitudes toward eating in a healthy and balanced way. In the present study, we investigated the psychometric properties of the Dutch translation of the Eating Competence Satter Inventory 2.0TM (ecSI 2.0TM), which was developed to assess eating attitudes and behaviors. A sample of 900 Flemish adolescents completed the ecSI 2.0TM DUTCH and two self-report measures on eating disorder symptoms and identity functioning (i.e., confusion and synthesis). Confirmatory factor analysis confirmed the four-factor structure of the ecSI 2.0TM DUTCH, and the resulting four subscales (i.e., Eating Attitudes, Food Acceptance, Internal Regulation, and Contextual Skills) showed acceptable-to-excellent reliability (αs ranging from 0.69 to 0.91). The ecSI 2.0TM DUTCH also demonstrated scalar invariance across sex and age (<17 years, ≥17 years). Males reported significantly higher ecSI 2.0TM DUTCH scores than females on the four subscales and the total scale. The two age groups did not significantly differ on the ecSI 2.0TM DUTCH scales. Finally, scores on the ecSI 2.0TM DUTCH subscales showed non-significant or small negative correlations with adolescents' Body Mass Index (BMI), large negative correlations with eating disorder symptoms and identity confusion, and large positive associations with identity synthesis. The Dutch translation of the ecSI 2.0TM is a valid and reliable instrument to assess eating competence skills in male and female adolescents.

Personal identity, somatic symptoms, and symptom-related thoughts, feelings, and behaviors in adolescence: Examining between- and within-person associations and the role of depressive symptoms

Recent literature highlights the complex relationship between personal identity and body-related pathology, yet there is a lack of integrative longitudinal research on the relationship between identity and somatic symptoms. The present study investigated the longitudinal associations between identity functioning and (psychological characteristics of) somatic symptoms, and examined the role of depressive symptoms in this relationship. A total of 599 community adolescents (Time 1: 41.3% female; M_age = 14.93, SD = 1.77, range = 12-18 years) participated in three annual assessments. Using cross-lagged panel models, a bidirectional relationship between identity and (psychological characteristics of) somatic symptoms, mediated by depressive symptoms, emerged at the between-person level; whereas only a unidirectional relationship from psychological characteristics of somatic symptoms to identity functioning, mediated by depressive symptoms, emerged at the within-person level. Identity and depressive symptoms were bidirectionally related at both levels. The present study suggests that adolescent identity development is closely related to somatic and emotional distress.

Normative body image development: A longitudinal meta-analysis of mean-level change

This meta-analysis synthesized longitudinal data on mean-level change in body image, focusing on the constructs of body satisfaction and dissatisfaction, body esteem, perceived attractiveness, valuation, self-objectification, and body shame. We searched five databases and accessed unpublished data to identify studies that assessed body image at two or more time points over six months or longer. Analyses were based on data from 142 samples representing a total of 128,254 participants. The age associated with the midpoint of measurement intervals ranged from 6 to 54 years. Multilevel metaregression models examined standardized yearly mean change, and the potential moderators of body image construct, gender, birth cohort, attrition rate, age, and time lag. Boys and men showed fluctuations in overall body image with net-improvements between ages 10 and 24. Girls and women showed worsening body image between ages 10 and 16, but improvements between ages 16 and 24. Change was greatest between ages 10 and 14, and stabilized around age 24. We found no effect of construct, birth cohort, or attrition rate. Results suggest a need to revise understandings of normative body image development: sensitive periods may occur somewhat earlier than previously believed, and body image may show mean-level improvements during certain age ranges.

Identity Formation, Body Image, and Body-Related Symptoms: Developmental Trajectories and Associations Throughout Adolescence

Emerging evidence highlights the intricate link between identity and one's body, however, integrative longitudinal research on this identity-body interplay is lacking. The current study used three-wave longitudinal data (Time 1: N = 403; 52.1% female; M_age = 14.85, SD = 0.89, range = 13-19 years) spanning two years (2019-2021; T1 and T2 being pre-pandemic, T3 peri-pandemic) to identify identity trajectory classes and examine their co-development with negative and positive body image and various body-related variables (i.e., sociocultural pressures, internalization of appearance ideals, self-objectification, appearance comparison, and eating disorder symptoms). First, four identity classes emerged using latent class growth analysis (achievement, moratorium, carefree diffusion, and troubled diffusion). Second, using multigroup latent growth curve modeling, adolescents in less adaptive identity trajectory classes (i.e., engaging less in pro-active processes and more in ruminative processes) displayed higher levels of negative body image and body-related symptoms. The current study testified to the clinically meaningful associations linking identity formation to adolescents' body image and other body-related symptoms.

Trajectories of adaptive and disturbed identity dimensions in adolescence: developmental associations with self-esteem, resilience, symptoms of depression, and borderline personality disorder features

To advance our understanding of adolescents' identity formation and how it may play into their psychological functioning, this study investigated developmental trajectory classes of adaptive and disturbed dimensions of identity formation, and whether adolescents belonging to different trajectory classes develop differently on self-esteem, resilience, symptoms of depression, and borderline personality disorder (BPD) features. Three-wave longitudinal data from 2,123 Flemish adolescents was used (54.2% girls; M_age = 14.64, range = 12-18 at T1). Results pointed to four trajectory classes of identity formation: adaptive identity, identity progression, identity regression, and diffused identity. The adaptive identity class presented with stable high levels of self-esteem and resilience, and stable low levels of symptoms of depression and BPD, whereas opposite results were obtained for the diffused identity class. The identity progression class reported an increase in self-esteem and resilience as well as a decrease in symptoms of depression and BPD, whereas opposite results were obtained for the identity regression class. These results emphasize that adaptive and disturbed dimensions of identity formation are closely related to markers of well-being and psychopathology among adolescents, and could help identify adolescents with an increased risk for negative psychological functioning or increased opportunity for positive psychological functioning.

Eating disorders and the nine symptoms of borderline personality disorder: A systematic review and series of meta-analyses

OBJECTIVE

Eating disorders and borderline personality disorder have high rates of comorbidity. However, the extent to which individual BPD symptoms are elevated in patients with EDs is largely unknown. Meta-analyses examined: (1) which of the nine BPD symptoms are especially elevated in individuals with versus without EDs, (2) whether particular ED subtypes have elevated levels of certain BPD symptoms, and (3) which BPD symptoms remain unstudied/understudied in relation to EDs.

METHODS

We performed nine separate meta-analyses (one for each BPD symptom) to compare levels of symptoms in patients with EDs versus healthy controls. A total of 122 studies (range = 4-34 studies across symptoms) were included.

RESULTS

Affective instability was the BPD symptom most elevated, while anger was the BPD symptom least elevated, in patients with EDs compared to controls. When comparing effect sizes across ED subtypes, anorexia nervosa binge-eating/purging subtype had the largest effect sizes for the greatest number of BPD symptoms, while effect sizes for AN restrictive subtype were not significantly larger than those of other EDs for any BPD symptom. The least studied BPD symptoms were identity disturbance and interpersonal difficulties.

DISCUSSION

These meta-analyses suggest that certain symptoms of BPD play a more prominent role in the comorbidity between BPD and EDs than others. Targeting affective instability when treating cases of comorbid ED and BPD may be especially likely to ameliorate the negative outcomes related to this comorbidity. Future research should further investigate identity disturbance and interpersonal difficulties in the context of EDs.

PUBLIC SIGNIFICANCE

Having an eating disorder and borderline personality disorder is a common comorbidity associated with a severe clinical presentation. BPD is characterized by nine distinct symptoms. This research examined levels of individual BPD symptoms in patients with versus without EDs. Findings can guide researchers and clinicians towards studying and treating symptoms that may be most relevant for BPD-ED comorbidity and in turn, improve outcomes for these patients.

Identity, self-blame, and body regard in NSSI: A test of moderated-mediation

BACKGROUND

Prior work suggests that an unstable identity is an important developmental factor impacting risk for non-suicidal self-injury (NSSI), partly because it can foster lowered self-esteem and self-blame coping styles. Theoretical models suggest that how one regards the self, including experiences of and reactions to one's body (e.g., body regard), impact how factors such as identity instability and coping styles influence NSSI behavior. This study tested whether body regard moderated the mediational effect of self-blame coping on the relationship between poor self-concept clarity and past-year NSSI.

METHODS

A sample of 1906 university students had complete data from an anonymous online questionnaires measuring self-concept clarity, self-blame coping, and past-year NSSI behaviors.

RESULTS

Past-year NSSI was reported by 23.5% of the sample. Moderated mediational regression analyses using the PROCESS macro for SPSS were run. Body regard significantly moderated the effects of self-blame coping and poor self-concept clarity on NSSI such that neither risk factor was associated with NSSI when body regard was high. Poor self-concept clarity also retained a significant, although weakened, direct relationship with NSSI in the full model.

CONCLUSIONS

Positive body regard is protective and appears to mitigate the strength of the relationships between poor self-concept clarity and self-blame coping on past year NSSI. When body regard is low or average, poor self-concept clarity is associated with increased NSSI, partly through the effect of self-blame coping. Treatments that address body- and self-perceptions related to self-concept may enhance the effectiveness of interventions used to reduce NSSI behavior.

Body-Related Attitudes, Personality, and Identity in Female Adolescents with Anorexia Nervosa or Other Mental Disorders

The psychological integration of body-related attitudes (BodyRA) is a critical developmental task in adolescence. Adolescents must adapt to their changing body image and body satisfaction. For young people, BodyRA (body dissatisfaction, bulimia, and drive for thinness) are connected to insecurities, which can disturb identity integration and personality development. Our goal was to evaluate the importance of BodyRA also for other mental disorders other than anorexia nervosa (AN), and the association between BodyRA with temperament and personality traits and identity diffusion. Data for the period of 2012 to 2019 were retrospectively analyzed from a convenience sample of patients in a child and adolescent psychiatric hospital (n = 114). The patients were 13 to 17 years of age and had a BMI of 11.9−36.1 kg/m2. As expected, BodyRA were found to be more pronounced in AN, as well as in borderline personality disorder (BPD), depression (DD), and attention deficit hyperactivity disorder (ADHD). BodyRA correlated significantly with internalizing problems in patients with DD (r = 0.428−0.565, p < 0.01) and BPD (r = 0.680, p < 0.01) as well as with BMI (r = 0.404, p < 0.01) in patients with DD. Moreover, we detected significant correlations with impaired identity development in patients with DD (r = 0.482−0.565, p < 0.01) and BPD (r = 0.681−0.703, p < 0.01). BodyRA also correlated significantly with the personality traits of harm avoidance (r = 0.377−0.541, p < 0.01) and self-directedness (r = −0.537−−0.635, p < 0.01) in DD. These personality traits and bulimia were used as predictors for identity diffusion in the investigated disorders of this study. We conclude that BodyRA, harm avoidance and self-directedness are associated with identity development in adolescent females with mental disorders.

Identity Development and Social-Emotional Disorders During Adolescence and Emerging Adulthood: A Systematic Review and Meta-Analysis

Depression, anxiety and eating disorders ("social-emotional disorders") are common during adolescence/emerging adulthood, periods of intense identity development. Despite this, there are few reviews of existing research on the relationship between symptoms of these disorders and ongoing identity development. This study systematically reviewed, narratively synthesized and meta-analyzed longitudinal investigations of the relationship between identity synthesis/confusion and depression, anxiety and eating disorders symptoms during adolescence/emerging adulthood. Three databases (PsycInfo, Medline, Embase) were searched. Study quality was systematically appraised, findings were qualitatively synthesized and (where possible) meta-analyzed. 20 studies (55% "fair" quality, 45% "poor" quality) were identified, including 13,787 participants (54.2% female, mean age = 14.48 years, range 10-29 years). The narrative synthesis found evidence of bidirectional relationships between identity synthesis/confusion and depression, anxiety and eating disorder symptoms. Meta-analyses and meta-regressions of a sub-sample of studies (N = 9) indicated no significant associations between identity synthesis or confusion and anxiety or depression symptoms. More high-quality research is needed before firm conclusions can be drawn.

Trauma and self-harming behaviors in high school students: The mediating role of identity formation

INTRODUCTION

This study investigated the link between trauma and self-harming behaviors in South African high school students, and examined the mediating role of identity formation. Traumatic experiences have been commonly associated with self-harming behaviors in adolescents. However, research addressing this association in non-Western countries is limited.

METHODS

A total of 552 South African high school students aged 13-21 (60.4% female; M_age = 16 years) were included in the study. Students completed self-report questionnaires on traumatic experiences, identity formation, and self-harming behaviors (disturbed eating behaviors and suicidal thoughts and behaviors).

RESULTS

Structural equation modelling indicated that the association between traumatic experiences and self-harming behaviors was partially mediated by identity formation. Traumatic experiences were associated with more identity diffusion, bulimia, and suicidal thoughts and behaviors. Identity diffusion, in turn, was associated with more drive for thinness, bulimia, body dissatisfaction, and suicidal thoughts and behaviors. Identity consolidation was positively associated with drive for thinness and negatively with body dissatisfaction and suicidal thoughts and behaviors. No moderation effects by gender or age were found.

CONCLUSIONS

Traumatic experiences were associated with higher levels of identity diffusion, which, in turn, were associated with more self-harming behaviors in South African high school students. These findings suggest the importance of focusing on identity diffusion in prevention and intervention programs targeting self-harming behaviors.

Identity Functioning and Eating Disorder Symptomatology: The Role of Cognitive Emotion Regulation Strategies

Introduction: Adolescence is the most critical life period for the development of eating disorder (ED) symptomatology. Although problems in identity functioning and emotion dysregulation have been proven important risk and maintaining factors of ED symptomatology, they have never been integrated in a longitudinal study. Methods: The present study is part of the Longitudinal Identity research in Adolescence (LIA)-study and aimed to uncover the temporal interplay between identity functioning, cognitive emotion regulation, and ED symptomatology in adolescence. A total of 2,162 community adolescents (Time 1: 54% female; M age = 14.58, SD = 1.88, range = 10-21 years) participated at three measurement points with 1-year intervals. They reported on identity functioning (identity synthesis and identity confusion), cognitive emotion regulation (rumination, catastrophizing, and positive reappraisal), and ED symptomatology (drive for thinness and bulimia symptoms). Results: Cross-lagged paths could be fixed for boys and girls and showed bidirectional associations between both dimensions of identity functioning and both rumination and catastrophizing over time. Similarly, these maladaptive cognitive emotion regulation strategies were bidirectionally related to ED symptomatology over time. Finally, indirect pathways pointed to bidirectional associations between both dimensions of identity functioning and bulimia symptoms through rumination and catastrophizing. Only unidirectional associations emerged for drive for thinness and almost no cross-lagged associations were found with positive reappraisal. Conclusion: The present study demonstrates that identity confusion may contribute to the development of ED symptomatology in adolescence through cognitive emotion dysregulation. It also reveals that these ED symptoms hamper identity development through emotion dysregulation. These results stress the importance of targeting both identity functioning and cognitive emotion regulation in the prevention and intervention of ED symptoms.

"I'm truly free from my eating disorder": Emerging adults' experiences of FREED, an early intervention service model and care pathway for eating disorders

BACKGROUND

Eating disorders (EDs) typically start during adolescence or emerging adulthood, periods of intense biopsychosocial development. FREED (First Episode Rapid Early Intervention for EDs) is a service model and care pathway providing rapid access to developmentally-informed care for emerging adults with EDs. FREED is associated with reduced duration of untreated eating disorder and improved clinical outcomes, but patients' experiences of treatment have yet to be assessed.

OBJECTIVE

This study aimed to assess emerging adults' experiences of receiving treatment through FREED.

METHOD

This study triangulated qualitative data on participants' experiences of FREED treatment from questionnaires and semi-structured interviews. Participants were 106 emerging adults (aged 16-25; illness duration < 3 yrs) (questionnaire only = 92; interview only = 6; both = 8). Data were analysed thematically.

RESULTS

Most participants reported psychological and behavioural changes over the course of treatment (e.g. reduction in symptoms; increased acceptance and understanding of difficulties). Participants identified five beneficial characteristics of FREED treatment: i) rapid access to treatment; ii) knowledgeable and concerned clinicians; iii) focusing on life beyond the eating disorder; iv) building a support network; v) becoming your own therapist.

CONCLUSION

This study provides further supports for the implementation of early intervention and developmentally-informed care for EDs. Future service model development should include efforts to increase early help-seeking.

Body Dissatisfaction as a Mediator between Identity Formation and Eating Disorder Symptomatology in Adolescents and Emerging Adults

Objective:

Eating disorder symptomatology generally develops during adolescence and emerging adulthood. Previous research has focused on the role of identity formation or body image in the development of eating disorder symptomatology, but integrative work is lacking. For this reason, the present cross-sectional study examined the mediating role of body dissatisfaction in the relation between identity formation and eating disorder symptomatology.

Method:

The sample comprised 659 participants between 15 and 30 years old (68.9% females; M_age = 19.44; SD_age = 3.99). All participants completed self-report measures on identity (Self-concept and Identity Measure), body dissatisfaction (the Body Image Feelings and Attitudes subscale of the Body Investment Scale and the Body Dissatisfaction subscale of the Eating Disorder Inventory-3), and eating disorder symptomatology (Eating Disorder Inventory-3). Latent variable modeling from a structural equation modeling approach was used.

Results:

First, identity formation significantly predicted eating disorder symptomatology. Additionally, indirect effects were found linking identity formation to eating disorder symptomatology through the mechanism of body dissatisfaction. No significant differences between males and females or between adolescents and emerging adults on direct or indirect effects were found.

Conclusion:

The present study indicated that body dissatisfaction mediated the relationship between identity formation and eating disorder symptomatology during mid-to-late adolescence and emerging adulthood. Provided that the present findings can be replicated in a future longitudinal study, they demonstrate that both identity formation and body dissatisfaction should be taken into account in prevention and intervention programs targeting eating disorder symptomatology.

Non-Suicidal Self-Injury and Eating Disordered Behaviors: An Update on What We Do and Do Not Know

PURPOSE OF REVIEW

The current report aims to summarize recent advances about the relationship between non-suicidal self-injury (NSSI) and eating disordered (ED) behaviors and highlights meaningful directions for future research.

RECENT FINDINGS

While there is solid evidence indicating a robust cross-sectional association between NSSI and ED behaviors, emerging evidence suggests that the temporal relationship between these behaviors may be bidirectional. Shared functions and risk factors may explain why these behaviors often co-develop. At the same time, little is still known about the psychosocial consequences of comorbid NSSI and ED engagement, and there is a lack of intervention studies that target these behaviors simultaneously. It is well-established that NSSI and ED behaviors frequently co-occur. The field should now turn to longitudinal designs to advance our understanding of the longer-term developmental and the shorter-term momentary relationship of these behaviors in daily life. Providing insight into these areas will help guide the deployment of evidence-based interventions that match the needs of clients who report comorbid NSSI and ED behaviors.
