Dialectical behavioral therapy for the treatment of adolescent eating disorders: a review of existing work and proposed future directions

United States-based practice guidelines for children and adolescents with eating disorders : Synthesis of clinical practice guidelines

INTRODUCTION

Several practice guidelines exist from professional organizations in the United States to support the assessment and management of eating disorders in children and adolescents. This manuscript synthesizes the key areas of overlap from these guidelines and provides directions for future research and alignment to improve care.

RECOMMENDATIONS

Consistent screening for eating disorders in primary care is recommended to ensure early identification and referral to treatment. Outpatient treatment supported by families, including family based treatment, is the first line of care recommended by guidelines. Multidisciplinary treatment teams benefit patients in covering the variety of aspects of health that eating disorders impact, including mental health, nutritional health, and physical health. Patients may require hospitalization under certain medical criteria such as bradycardia or specific lab abnormalities.

CONCLUSIONS

Guidelines show consensus on the importance of early identification and treatment access, involvement of family in treatment, and the use of a multidisciplinary treatment team. However, future work is needed to guide care of Avoidant/Restrictive Food Intake Disorder (ARFID), as well as the impact of weight inclusive care and the development of validated screening tools for children and adolescents for all eating disorders.

Anorexia Nervosa in Comorbidity With Borderline Personality Disorder in Adolescence: A Specific Clinical Endophenotype?

OBJECTIVE

Anorexia nervosa and borderline personality disorder are often associated and share some core elements, including emotional dysregulation and affective instability. Nevertheless, the association of these two conditions in adolescence is still little studied.

METHOD

The present study aims at investigating, through a multidimensional assessment, the psychopathological characteristics of adolescents affected by anorexia nervosa in comorbidity with borderline personality disorder on a sample of 127 female adolescents, through the comparison with adolescents with borderline personality disorders and adolescents with anorexia nervosa. All participants completed a validated psychometric battery assessing alexithymia (Toronto Alexithymia Scale-20), depression (Children's Depression Inventory), psychological symptoms (Symptom Checklist-90-Revised) and psychological symptoms relevant in eating disorders (Eating Disorders Inventory-3).

RESULTS

Adolescents with anorexia nervosa in comorbidity with borderline personality disorder show intermediate features between the two disorders individually in the general psychopathological profile, but a peculiar psychological profile regarding the eating symptomatology, with worse features compared to adolescents with the sole anorexia nervosa.

CONCLUSIONS

Results suggest a peculiar clinical and psychopatological endophenotype in adolescents with anorexia nervosa in comorbidity with borderline personality disorders, indicating the need to define specific and tailored treatment for this population.

Clinical Intervention Strategies and Family Dynamics in Adolescent Eating Disorders: A Scoping Review for Enhancing Early Detection and Outcomes

Background: This systematic review investigated the impact of familial factors on individuals aged 10-17 who have clinical signs or symptoms of eating disorders. Simultaneously, it scrutinized the involvement of the family in therapy, as well as other forms of intervention. Methods: The PsycINFO, PubMed, and Scopus databases were used to search for research material comprehensively. After applying specific criteria, 46 articles were deemed suitable and included in the systematic review. The study comprised a cohort of 4794 adolescents who received a diagnosis of either Anorexia Nervosa (AN), Bulimia Nervosa (BN), or Binge-Eating Disorder (BED). In addition, controls were utilized for 1187 adolescents, 1563 parents, 1809 siblings, and 11 other relatives. Results: The connection between family factors and eating disorders is primarily determined by the families' level of functioning, satisfaction with the family dynamic, parents' attitudes toward their children, and the role of food within the family system. Family Therapy was the most used psychotherapeutic approach in the treatment of AN. The incidence of reports in BN closely paralleled that of Cognitive-Behavioral Therapy (CBT) models. Articles about (Enhanced) CBT were exclusively associated with BED. Conclusions: Family-based approaches are crucial in comprehending, preventing, and addressing eating disorders in adolescents. Incorporating the study of family dynamics and actively engaging families in the treatment process can significantly enhance recovery rates and decrease the occurrence of relapses.

A Narrative Review of the Efficacy of Interventions for Emotional Dysregulation, and Underlying Bio-Psycho-Social Factors

In this narrative, comprehensive, and updated review of the literature, we summarize evidence about the effectiveness of interventions aimed at reducing emotion dysregulation and improving emotion regulation in children, adolescents, and adults. After introducing emotion dysregulation and emotion regulation from a theoretical standpoint, we discuss the factors commonly associated with emotion regulation, including neurobiological and neuropsychological mechanisms, and the role of childhood adverse experiences and psycho-social factors in the onset of emotion dysregulation. We then present evidence about pharmacological and non-pharmacological interventions aiming at improving emotion dysregulation and promoting emotion regulation across the lifespan. Although our review was not intended as a traditional systematic review, and the search was only restricted to systematic reviews and meta-analyses, we highlighted important implications and provided recommendations for clinical practice and future research in this field.

Identifying overcontrol and undercontrol personality types among young people using the five factor model, and the relationship with disordered eating behaviour, anxiety and depression

BACKGROUND

Overcontrol and undercontrol personality types have been associated with an increase in eating pathology, depression and anxiety. The aim of the research was to explore whether latent overcontrol and undercontrol personality types could be identified using cluster analysis of the facets of the five factor model (FFM). We further aimed to understand how these personality types were associated with eating pathology, depressed mood and anxiety.

METHODS

A total of 561 participants (394 women and 167 men), aged 16-30 years in Australia completed a survey designed to assess disordered eating, FFM personality traits, anxiety, depression and stress. A systematic four-step process using hierarchical, k-means, and random forest cluster analyses were used to identify a meaningful 3-cluster solution.

RESULTS

The results revealed a cluster solution that represented overcontrol, undercontrol and resilient personality types, and highlighted facets of the FFM that were associated with each type. Both overcontrol and undercontrol personality types were associated with increased clinical symptoms compared to the resilient types.

CONCLUSIONS

It was concluded that FFM facets may potentially be more meaningful than broad domains in identifying personality types, and that both overcontrol and undercontrol personality types are likely associated with increased clinical symptoms.

Expanding considerations for treating avoidant/restrictive food intake disorder at a higher level of care

Existing descriptions of the treatment of avoidant/restrictive food intake disorder (ARFID) at higher levels of care (HLOC) for eating disorders are limited, despite HLOC settings frequently serving patients with ARFID. The purpose of this commentary is to expand on the preliminary literature that describes pediatric ARFID treatment at HLOC by describing two specific components of our approach to treating pediatric ARFID that may not yet have traction in the current literature. Specifically, we highlight the utility of (1) treatment accommodations that appropriately account for patients' neurodevelopmental needs (e.g., executive functioning, sensory processing) and (2) the adjunctive use of Dialectical Behavior Therapy (DBT) elements within family-based pediatric ARFID treatment. We also describe necessary future directions for research in these domains to clarify if incorporating these considerations and approaches into pediatric ARFID treatment at HLOC does indeed improve treatment outcomes.

Integration of Physical Exercise in Feeding and Eating Disorders and Exercise Dependence Treatment

The physical and mental benefits of physical activity are unquestionable. However, while much research has been done into the benefits of exercise in the prevention and treatment of numerous physical illnesses, the study of the impact of exercise on psychopathological conditions is more recent. Moreover, for several reasons, there are some grey areas and some controversy regarding physical exercise in patients with feeding and eating disorders such as anorexia nervosa or bulimia. This controversy may stem from several issues. On the one hand, because there is a fine line between healthy physical exercise and over-exercising (which may become exercise dependence); on the other hand, because of the strong association that some mental disorders (such as anorexia) have with disruptive exercise use, with several clinicians and researchers implying that exercise may eventually cause a feeding and eating disorder.

Adolescent Eating Disorders: Early Identification and Management in Primary Care

Eating disorders are complex, potentially life-threatening conditions characterized by disruptive eating behaviors that significantly impact physical and psychosocial functioning. The adolescent population is at an increased risk of developing eating disorders because of developmental changes affecting their perception. Eating disorders are associated with devastating medical complications and high mortality rates if left untreated. As the prevalence of eating disorders among adolescents continues to increase, it is important that clinicians are knowledgeable about early signs of disordered eating and facilitate timely evaluation and care coordination. Newly released clinical guidelines from the American Academy of Pediatrics are reviewed for early identification and management of eating disorders in children and adolescents. The epidemiology, risk factors, and medical complications for common eating disorders in primary care such as anorexia nervosa, bulimia nervosa, and binge eating disorder, are presented. An approach to screening for eating disorders, clinical assessment, and treatment options are outlined.

Evaluation of an Intensive Program for Children With Co-occurring Medical and Emotional Disorders

The study objective was to assess clinical outcomes and cost avoidance of an intensive day treatment program for children with co-occurring chronic medical disease and emotional problems. Intensive day treatment programs for this population are uncommon, and their effectiveness has not been previously reported. A total of 175 children were enrolled during the 3-year study period. Children had more than 30 medical diagnoses including chronic pain, dysautonomia, neurologic disorders, and diabetes. Complete utilization data were available for 118 patients, and demonstrated decreased hospitalizations and increased behavioral health visits during the 12 months post program compared with 12 months prior. Private insurance and female sex were associated with reduced utilization costs after program participation. Estimated avoided cost for the 118 children was $1 111 485. Patients reported significant improvements in somatic symptoms, sleep problems, inattention, depression, anger, and anxiety. Limited data indicated improvements in school attendance. Additional research addressing other outcomes, such as school-related symptoms, would be helpful.

Emotion Dysregulation and Eating Disorder Symptoms: Examining Distinct Associations and Interactions in Adolescents

Emotion dysregulation has been posited as a key transdiagnostic factor of mental health difficulties, including eating disorders. However, how this transdiagnostic factor interacts with the disorder-specific factor of weight and shape concerns remains unclear. The current study examined whether emotion dysregulation is associated with eating disorder behaviors over and above the association between weight and shape concerns and whether these two factors interacted. The current study used data from two samples, a community sample of high school students (n = 2699), and a clinical sample of adolescents receiving outpatient treatment for an eating disorder (n = 149). Participants completed self-report measures on their eating behaviors, weight/shape concerns, and emotion dysregulation. Findings showed that emotion dysregulation had a unique association with engaging in binge eating and purging (community sample only). Weight and shape concerns were found to have a unique association with engaging in binge eating, fasting, purging, and driven exercise (community sample only). Additionally, weight and shape concerns moderated the association between emotion dysregulation and the probability of engaging in binge eating and driven exercise, whereby the strongest association between emotion dysregulation and these behaviors were observed among adolescents with the lowest levels of weight and shape concerns. Regarding the frequency of eating disorder behaviors, emotion dysregulation had a unique association with severity of binge eating and fasting. Weight and shape concerns were uniquely associated with severity of fasting and driven exercise (community sample only). Findings suggest that emotion dysregulation is a distinct factor of eating disorder behaviors among adolescents.

Emotion regulation in adolescents with anorexia and bulimia nervosa: Differential use of adaptive and maladaptive strategies compared to healthy adolescents

OBJECTIVE

Adolescents with anorexia (AN) and bulimia nervosa (BN) often struggle with emotion regulation (ER). These difficulties have predominantly been assessed across emotions, without considering adaptive and maladaptive ER separately. We compared adolescents with AN or BN to healthy adolescents (HCs) regarding the adaptive and maladaptive ER of three emotions.

METHOD

A treatment-seeking sample of 197 adolescents (atypical/full-threshold AN: N = 118, atypical/full-threshold BN: N = 32; HC: N = 47) reported emotion-specific ER with the FEEL-KJ questionnaire. Mixed models were calculated for adaptive and maladaptive ER to assess differences between emotions (anxiety, anger, and sadness) and groups (AN, BN, and HC).

RESULTS

Main effects of emotion (p < .001) and group (p < .001) were found, but no interaction effects were found (p > .05). Post hoc tests showed lower maladaptive and higher adaptive ER for anxiety than anger or sadness (p < .001). AN and BN reported lower adaptive (p < .001) and higher maladaptive ER than HCs (p < .001). BN showed the highest levels of maladaptive ER (p = .009).

DISCUSSION

The differences between AN and BN in adaptive and maladaptive ER should be considered. Furthermore, investigating differences in ER of other emotions in eating disorders might be promising.

Emotion dysregulation across the span of eating disorder symptoms: Findings from a community sample of adolescents

OBJECTIVE

Emotion dysregulation is proposed as a key factor within eating disorder pathology. However, less is known about specific emotion regulation difficulties experienced by adolescents with varying levels of eating disorders symptoms. The present study examined the relationship between eating disorder behaviors and specific facets of emotion dysregulation, and differences in emotion dysregulation between eating disorder diagnostic groups.

METHOD

Participants were 2,783 adolescents, 11-19 years (M = 14 years, 9 months, SD = 1 year, 6 months), who completed self-report measures as part of the EveryBODY study. Adolescents were identified as not having eating disorder symptoms (n = 2,122) or meeting diagnostic criteria for symptoms of specific eating disorder, including: anorexia nervosa or atypical anorexia nervosa (n = 57), bulimia nervosa (n = 136), binge-eating disorder (n = 57), other specified feeding or eating disorder characterized by binge eating or purging (n = 381), and unspecified feeding or eating disorder (n = 30).

RESULTS

Binge eating, driven exercise, and fasting were each uniquely associated with emotion dysregulation, whereas purging was not. Similar findings were obtained within specific domains of emotion dysregulation. Findings from diagnostic groups showed a significant main effect of diagnosis on overall emotion dysregulation and most domains of emotion dysregulation. Adolescents with eating disorder symptoms consistently reported higher emotion dysregulation compared to those without these symptoms.

DISCUSSION

Findings indicate that emotion dysregulation is a key factor across eating disorder pathology, and potential treatment target across the spectrum of eating disorder diagnoses in adolescents.

Challenging rigidity in Anorexia (treatment, training and supervision): questioning manual adherence in the face of complexity

BACKGROUND

Anorexia Nervosa is a debilitating illness. While there have been many advancements to treatment protocols and outcomes for people with eating disorders, the field acknowledges there remains considerable room for improvement. This timely Special Edition of the Journal of Eating Disorders has invited those of us in the field to consider a range of topics in aid of this task, including potential modifications and implementation of evidence-based practice, specific and common psychotherapy factors, treatment manuals, adherence and individualising treatment approaches for individuals and families. BODY: In this paper, we briefly outline the key manualised treatments currently available to treat children, adolescents and adults with Anorexia Nervosa, considering the benefits, potential reasons for adaptations and limitations. We then review the current evidence for training strict adherence to treatment manuals which is often a key focus in training and supervision, questioning the association of increased treatment adherence with improved therapeutic outcome. We then summarise some key evidence behind other therapeutic factors which have been demonstrated to affect outcome regardless of which manual is implemented, such as readiness to change and therapeutic alliance.

CONCLUSION

The paper concludes with implications and considerations for future research, clinical guidelines, training and supervision, highlighting the need to consider the therapeutic relationship and processes alongside manual content to conduct best evidence-informed practice.

A mixed methods exploratory evaluation of burnout in frontline staff implementing dialectical behavior therapy on a pediatric eating disorders unit

BACKGROUND

Eating disorders are life-threatening illnesses that commonly affect adolescents. The treatment of individuals with eating disorders can involve slow treatment progression and addressing comorbidities which can contribute to staff burnout. Dialectical behavior therapy (DBT) has emerged as a viable treatment option and has reduced staff burnout in several other settings. Our aim was to describe frontline staff burnout using mixed methodology on a DBT-trained combined inpatient/day hospital unit for pediatric eating disorders.

METHOD

Frontline staff were trained to provide DBT skills for adolescents with eating disorders. Twelve months following the training and implementation, they completed the Copenhagen Burnout Inventory (CBI) and a qualitative interview. Directed and summative content analyses were used.

RESULTS

Eleven frontline staff including nurses, child life specialists and child and youth workers participated. The CBI revealed that only one staff member experienced high personal burnout, while another experienced high client-related burnout. Qualitative data indicated that all frontline staff felt DBT had the potential to reduce burnout.

CONCLUSION

Qualitative data indicate that staff believe that DBT may hold promise in reducing burnout for pediatric frontline staff who treat children and adolescents with eating disorders. Further study is needed. Understanding burnout is particularly important for nursing staff in inpatient and day hospital settings for eating disorders, as nursing staff generally have the most frequent patient contact; thought to be a risk factor for burnout. The reduction of burnout can prevent detrimental effects on job performance, personal well-being, and patient outcomes. Our exploratory study shows that frontline staff believe that DBT may have the potential to reduce burnout in staff treating children and adolescents with eating disorders in a combined inpatient/day hospital setting. Further study is needed in this area.

Intolerance of Uncertainty and Eating Disorder Symptoms Over the Course of Intensive Treatment

There is a critical need to identify processes that may influence outcome in existing treatments for eating disorders (EDs). Intolerance of uncertainty (IU), which refers to excessive distress regarding uncertain situations, is a well-established feature of anxiety disorders. Emerging work suggests that IU decreases over the course of cognitive-behavioral treatments and may relate to better treatment outcomes. As some literature has suggested IU may functionally maintain ED symptoms, testing whether changes in IU over treatment relate to outcome may result in the identification of novel treatment targets. This study aimed to build upon past work documenting links between IU and ED symptoms by exploring changes in IU over treatment and links between early change in IU (1-month) and discharge symptoms. Participants (N = 274) receiving partial hospitalization treatment completed the Eating Pathology Symptoms Inventory and Intolerance of Uncertainty Scale at admission, 1-month post-admission, and discharge. Results suggested that IU significantly reduced from admission to discharge and that reductions in IU scores from admission to 1-month related to cognitive restraint, dietary restriction, and body image at discharge. However, this pattern did not hold for exercise, binge eating, or purging. Altogether, these results replicate past work supporting IU as a common feature across ED diagnoses and provide initial data suggesting that targeting IU early in treatment may enhance treatment outcomes.
