A Narrative Review of Outcome Studies for Residential and Partial Hospital‐based Treatment of Eating Disorders

OBJECTIVE The objective of this study was to review the current eating disorders outcome literature after residential or partial hospitalization programme (PHP) treatment. METHOD Articles were identified through a systematic search of PubMed and PsycINFO. RESULTS Twenty-two PHP and six residential treatment studies reported response at discharge and tended to find improvement. Fewer studies (nine PHP and three residential) reported outcome at some interval after discharge from treatment. These tended to find sustained improvement. A substantial proportion of patients were lost to follow-up, particularly for residential treatment. Only two follow-up studies used controlled trials; both showed efficacy for PHP compared with inpatient treatment with regard to maintaining symptom remission. CONCLUSIONS Improvement at discharge may not predict long-term outcome. Long-term follow-up studies were confounded by high dropout rates. While higher levels of care may be essential for reversing malnutrition, there remains a lack of controlled trials showing long-term efficacy, particularly for residential treatment settings.

Adapting Family-Based Treatment for Adolescent Anorexia Nervosa Across Higher Levels of Patient Care

An increasing body of evidence supports the use of family-based treatment (FBT) in medically stable outpatient presentations of adolescent anorexia nervosa, although there is relatively less research on adapting evidence-based treatment approaches in more intensive levels of patient care. The integration of FBT, which centrally leverages parental involvement in more intensive levels of care which typically require greater clinical management, requires careful consideration. We provide an overview of several key practical and theoretical considerations when adjusting the delivery of FBT across more intensive levels of patient care, providing clinical guidelines for the delivery of FBT while ensuring fidelity to the core theoretical tenets. Implications for clinical practice and future research are discussed.

Integrating Family-Based Treatment and Dialectical Behavior Therapy for Adolescent Bulimia Nervosa: Preliminary Outcomes of an Open Pilot Trial

Adolescent bulimia nervosa (BN) remains relatively understudied, and the complex interaction between core eating psychopathology and emotional regulation difficulties provides ongoing challenges for full symptom remission. In an open pilot trial, we aimed to investigate the efficacy of a program integrating family-based treatment (FBT) and dialectical behavior therapy (DBT) in treating adolescent BN, without exclusion criteria. Participants were 35 adolescents who underwent partial hospital treatment for BN, and outcomes included measures of core BN pathology and emotional regulation difficulties, as well as parental measures of self-efficacy, completed at intake and discharge. Results indicate significant improvements in overall eating disorder pathology, t(68) = 4.52, p = .002, and in core BN symptoms, including objective binge episodes, t(68) = 2.01, p = .041, and self-induced vomiting, t(68) = 2.90, p = .005. Results also illustrated a significant increase in parental efficacy throughout the course of treatment, t(20) = .081, p = .001, although no global improvement in difficulties in emotion regulation was noted, t(68) = 1.12, p = .285. These preliminary findings support the utility of this integration of FBT and DBT, although raise interesting questions as to the mechanism of symptom remission.

Psychometric Evaluation and Norms for the Multidimensional Assessment of Interoceptive Awareness (MAIA) in a Clinical Eating Disorders Sample

Altered interoceptive awareness (IA) has been implicated in the pathophysiology of eating disorders; however, few comprehensive self-report measures of IA exist in eating disorders. The present study sought to validate the Multidimensional Assessment of Interoceptive Awareness (MAIA), originally developed to assess IA in individuals practicing mind-body therapies, in an eating disorder sample. Adult and adolescent patients (n = 376) completed assessments upon admission to a partial hospital programme. Analyses examined the factor structure of the MAIA, scale means, scale-scale correlations, internal consistency and construct validity. Analyses also examined associations between MAIA subscales and eating disorder symptoms. Results supported the original eight-factor structure of the MAIA. Internal consistency was acceptable, and the scales converged with associated measures. Importantly, Not Distracting, Self-regulation, Body Listening and Trusting were most strongly associated with eating disorder symptoms. Results support use of the MAIA among eating disorders and provide further support for the relevance of IA in eating disorders. Copyright

The Integration of Family-Based Treatment and Dialectical Behavior Therapy for Adolescent Bulimia Nervosa: Philosophical and Practical Considerations

Dialectical behavior therapy (DBT) and family-based treatment (FBT) are two evidence-based interventions that have been applied in the treatment of bulimia nervosa (BN) in adolescents. While DBT focuses on providing skills for coping with emotion dysregulation that often co-occurs with BN, FBT targets the normalization of eating patterns. The purpose of the current article is to introduce an integration of both treatments to provide a more comprehensive approach that targets the full scope of the disorder. We provide a review of the conceptual similarities and differences between FBT-BN and DBT along with strategies to guide a blended treatment approach. Given the strengths and limitations of either independent treatment, DBT and FBT-BN complement one another and together can address the range of symptoms and behaviors typically seen in adolescent BN.

Deconstructing “Atypical” Eating Disorders: an Overview of Emerging Eating Disorder Phenotypes

Recent changes to the diagnostic framework of eating disorders (ED’s) in DSM-5 were introduced to reduce the large preponderance of cases falling within the residual and undifferentiated category. However, current reports continue to illustrate overrepresentation of cases in this residual category, suggesting that clinical reality comprises more diverse ED psychopathology than is accounted for in the current diagnostic spectrum. However, with emerging evidence preliminarily delineating several additional distinct phenotypes, we aim to provide a narrative overview of emerging ED phenotypes which (i) are not currently located as a specific diagnostic category in diagnostic criteria for ED’s, (ii) centrally feature ED psychopathology, and (iii) have emerging empirical evidence suggesting the distinct nature of the syndrome. A greater awareness of these emerging phenotypes will likely facilitate accurate diagnostic practice and may also serve to facilitate further empirical efforts.

Treating Eating Disorders at Higher Levels of Care: Overview and Challenges

Higher levels of care (HLC)—including inpatient hospitalization, residential treatment, partial hospitalization, and intensive outpatient treatment—are frequently utilized within routine care for eating disorders. Despite widespread use, there is limited research evaluating the efficacy of HLC, as well as clinical issues related to care in these settings. This review describes the different levels of care for eating disorders and briefly reviews the most up-to-date guidelines and research regarding how to choose a level of care. In addition, as HLC approaches for ED continue to be developed and refined, pragmatic and conceptual challenges have emerged that provide barriers to clinical efficacy and the execution of high-quality treatment research. This review includes a discussion of various issues specific to HLC, as well as a summary of recent literature addressing them.

Differences in emotion regulation difficulties among adults and adolescents across eating disorder diagnoses

OBJECTIVE Although much empirical attention has been devoted to emotion regulation (ER) in individuals with eating disorders, little is known about ER across a wide age range and among different ED subtypes. The current study sought to examine ER in a sample of eating disorder patients. METHOD A total of 364 adults and adolescents with anorexia nervosa restricting subtype (AN-R), anorexia nervosa binge/purge subtype (AN-BP), or bulimia nervosa (BN) were assessed with the Difficulties in Emotion Regulation Scale (DERS). RESULTS Older ages were associated with higher DERS total, nonacceptance, goals, and impulsivity scores. When controlling for age, patients with BN and AN-BP had higher overall DERS scores than those with AN, and there were some differences among diagnostic subtypes on specific facets of ER. CONCLUSIONS These results indicate that treatments for emotion dysregulation may be applied across eating disorder diagnoses and ages, and inform how these strategies apply to different diagnostic groups.

The Impact of Alexithymia on Emotion Dysregulation in Anorexia Nervosa and Bulimia Nervosa over Time

Research supports that anorexia nervosa-restricting subtype (AN-R) and bulimia nervosa (BN) are associated with emotion regulation difficulties and alexithymia. However, the impact of diagnosis on the relationship between these constructs is less well understood. The purpose of the present study was to examine whether eating disorder diagnosis moderated the association between admission alexithymia and emotion regulation through discharge. Adult patients with AN-R (n = 54) and BN (n = 60) completed assessments at treatment admission and discharge from a partial hospital program. Eating disorder diagnosis moderated the association between admission alexithymia levels and change in global emotion dysregulation, impulse control difficulties and access to emotion regulation strategies. At higher levels of admission alexithymia, there were no differences between AN-R and BN on emotion dysregulation, whereas at lower levels of alexithymia, AN-R patients demonstrated lower levels of emotion dysregulation. Results imply that difficulties with alexithymia appear to have a greater impact on emotion dysregulation for AN-R patients. Copyright

An open trial targeting emotional eating among adolescents with overweight or obesity

ABSTRACT Emotional eating is associated with obesity and disordered eating in adolescents, and thus, is an important target for treatment. We developed a program called PEER (Preventing Emotional Eating Routines), which incorporates emotion regulation skills with behavioral weight loss and parenting techniques for adolescents who are overweight or obese (OW/OB) and their parent. This open label trial evaluated the feasibility, acceptability, and initial efficacy of the PEER program. Thirty adolescents who were OW/OB (86.7% female; mean age = 14.6 years (SD = 1.2); Body Mass Index (BMI) = 34.0 kg/m2 (SD = 5.6); 33.3% White non-Hispanic) and their parent (66.7% biological mother) participated in a 4-month treatment and 3-month follow-up. The PEER program was well accepted. Initial efficacy showed significant decreases in emotional eating, and there were trends towards weight loss and a decrease in emotion dysregulation. This trial provides preliminary evidence for the feasibility, acceptability, and initial efficacy of the PEER program among adolescents who are OW/OB and their parent. Further treatment development and randomized controlled studies are needed.
