Enhanced Cognitive Behavior Therapy: A Single Treatment for All Eating Disorders

Eating disorders are serious mental illnesses affecting a significant proportion of women and a smaller number of men. Approximately half of those with an eating disorder (ED) will not meet the criteria for anorexia or bulimia nervosa, and will be diagnosed with an eating disorder not otherwise specified (EDNOS). Until recently, there were no recommended treatments for EDNOS. This article provides an overview of enhanced cognitive behavior therapy, a validated treatment for all forms of EDs.     

Guided self-help for disordered eating: A randomised control trial

Treatment guidelines recommend evidence-based guided self-help (GSH) as the first stage of treatment for bulimia nervosa and binge eating disorder. The current randomised control trial evaluated a cognitive behavioural therapy-based GSH pack, ‘Working to Overcome Eating Difficulties,’ delivered by trained mental health professionals in 6 sessions over 3 months. It was congruent with the transdiagnostic approach and so was intended as suitable for all disordered eating, except severe anorexia nervosa. Eighty one clients were randomly allocated to either a GSH or waiting list condition. Eating disorder psychopathology (EDE-Q), key behavioural features and global distress (CORE) were measured at pre- and post-intervention, and 3- and 6-month follow-up. Results showed significant improvements in eating disorder psychopathology, laxative abuse, exercise behaviours, and global distress, with the GSH condition being superior to the waiting list on all outcomes. Treatment gains were maintained at 3 and 6 months. This study adds to the evidence supporting GSH for disordered eating, including EDNOS. However, further work is needed to establish the factors that contribute to observed therapeutic improvements and determine for whom GSH is most suitable.     

Exposure-Based Family Therapy (FBT-E): An Open Case Series of a New Treatment for Anorexia Nervosa

The overlap between anorexia nervosa (AN) and anxiety disorders has led to the development of anxiety-based etiological models of AN and anxiety-based interventions for AN, including exposure treatment. Family-based treatment (FBT) is an efficacious intervention for adolescents with AN; however, it has recently been proposed that FBT accomplishes parent-facilitated exposure and habituation to food and related triggers in the individual's natural environment. FBT was recently altered to include an explicit exposure component that targets the broad construct of anxiety, including fear, worry, and disgust. This case series examines the application of FBT with an exposure component (FBT-E) to a group of adolescents meeting diagnostic criteria for AN (n = 4) and eating disorder not otherwise specified–restricting type (SAN, n = 6). Ten outpatients (ages 12–17, mean age: 15.28) participated in a course of FBT-E. Session-by-session weight was examined, along with BMI at pre- and posttreatment and responses to self-report measures of eating disorder symptoms (Eating Disorder Examination Questionnaire; EDE-Q), depression and anxiety. Parent reports of their adolescents' anxiety were also collected. The results of this study provide preliminary evidence that FBT-E may effectively target disordered eating and anxiety symptoms and may be a viable alternative to traditional FBT. Implications and future directions are discussed.     

Cognitive behaviour therapy for eating disorders: a "transdiagnostic" theory and treatment

This paper is concerned with the psychopathological processes that account for the persistence of severe eating disorders. Two separate but interrelated lines of argument are developed. One is that the leading evidence-based theory of the maintenance of eating disorders, the cognitive behavioural theory of bulimia nervosa, should be extended in its focus to embrace four additional maintaining mechanisms. Specifically, we propose that in certain patients one or more of four additional maintaining processes interact with the core eating disorder maintaining mechanisms and that when this occurs it is an obstacle to change. The additional maintaining processes concern the influence of clinical perfectionism, core low self-esteem, mood intolerance and interpersonal difficulties. The second line of argument is that in the case of eating disorders shared, but distinctive, clinical features tend to be maintained by similar psychopathological processes. Accordingly, we suggest that common mechanisms are involved in the persistence of bulimia nervosa, anorexia nervosa and the atypical eating disorders. Together, these two lines of argument lead us to propose a new transdiagnostic theory of the maintenance of the full range of eating disorders, a theory which embraces a broader range of maintaining mechanisms than the current theory concerning bulimia nervosa. In the final sections of the paper we describe a transdiagnostic treatment derived from the new theory, and we consider in principle the broader relevance of transdiagnostic theories of maintenance.     

Exploring possible mechanisms of change in family‐based treatment for adolescent bulimia nervosa

Objective: Mediators of treatment for family‐based treatment are explored for outcomes among adolescents with bulimia nervosa (BN). Method: Using data from a recently completed randomized clinical trial (RCT) comparing family‐based treatment (FBT) to supportive psychotherapy (SPT) we examined possible mediators of treatment outcome. Results: Results suggest that FBT‐BN was more effective than SPT in producing remission by virtue of achieving greater reductions in eating disorder psychopathology by mid‐treatment. Specifically, reductions in cognitions related to BN as assessed by the EDE appeared to be the differentiating mechanism. Conclusion: It is reasonable to hypothesize that change in the EDE subscales mediates outcome for FBT‐BN. Future studies with sufficient power to examine this possibility as an a priori hypothesis would help to better understand how FBT‐BN works and may also help to guide future treatment refinement and development.     

Scham und Familienbeziehungen bei Bulimie

Background

Empirical studies show a relationship between family factors and disturbed eating behavior. Feelings of shame are associated with a higher level of eating disorder symptoms and with family relations perceived as being dysfunctional. Thus shame can be understood as a mediator of the relationship between dysfunctional family relations and eating disorder symptoms.

Material and methods

For 69 female patients, including 55 with bulimia nervosa and 14 with eating disorder not otherwise specified (EDNOS) between 14 and 22 years of age, who participated in a comparative study of psychotherapy outcome, eating disorder symptoms (EDI, EDE-Q), general psychiatric symptoms severity (SCL-90R), level of shame (TESE-KJ) and perceived family relations (FB-A) were measured at the beginning of psychotherapy.

Results

The higher the feeling of shame the more dysfunctional the perceived family relationships were and the more the eating disorders and general symptoms severity were reported. Shame was a partial mediator of the relationship between family functionality and symptoms.

Discussion

Feelings of shame could originate in dysfunctional family relationships but could also evoke more negative perceptions of interpersonal relationships. The direction of causality could not be proven in the correlative design; nevertheless, shame contributes to an understanding of the mechanisms between dysfunctional family relationships and eating disorder symptoms.     

Moderators and mediators of remission in family-based treatment and adolescent focused therapy for anorexia nervosa

Few of the limited randomized controlled trails (RCTs) for adolescent anorexia nervosa (AN) have explored the effects of moderators and mediators on outcome. This study aimed to identify treatment moderators and mediators of remission at end of treatment (EOT) and 6- and 12-month follow-up (FU) for adolescents with AN (N = 121) who participated in a multi-center RCT of family-based treatment (FBT) and individual adolescent focused therapy (AFT). Mixed effects modeling were utilized and included all available outcome data at all time points. Remission was defined as ≥ 95% IBW plus within 1 SD of the Eating Disorder Examination (EDE) norms. Eating related obsessionality (Yale-Brown-Cornell Eating Disorder Total Scale) and eating disorder specific psychopathology (EDE-Global) emerged as moderators at EOT. Subjects with higher baseline scores on these measures benefited more from FBT than AFT. AN type emerged as a moderator at FU with binge-eating/purging type responding less well than restricting type. No mediators of treatment outcome were identified. Prior hospitalization, older age and duration of illness were identified as non-specific predictors of outcome. Taken together, these results indicate that patients with more severe eating related psychopathology have better outcomes in a behaviorally targeted family treatment (FBT) than an individually focused approach (AFT).     

Psychological treatment of eating disorders

Significant progress has been achieved in the development and evaluation of evidence-based psychological treatments for eating disorders over the past 25 years. Cognitive behavioral therapy is currently the treatment of choice for bulimia nervosa and binge-eating disorder, and existing evidence supports the use of a specific form of family therapy for adolescents with anorexia nervosa. Important challenges remain. Even the most effective interventions for bulimia nervosa and binge-eating disorder fail to help a substantial number of patients. A priority must be the extension and adaptation of these treatments to a broader range of eating disorders (eating disorder not otherwise specified), to adolescents, who have been largely overlooked in clinical research, and to chronic, treatment-resistant cases of anorexia nervosa. The article highlights current conceptual and clinical innovations designed to improve on existing therapeutic efficacy. The problems of increasing the dissemination of evidence-based treatments that are unavailable in most clinical service settings are discussed.     

Parent-Facilitated Behavioral Treatment for Avoidant/Restrictive Food Intake Disorder: A Case Report

Avoidant/restrictive food intake disorder (ARFID), which was introduced in DSM-5, may be one of the most functionally impairing eating disorders, yet little is known regarding risk factors, prevalence, or efficacious treatment models for the disorder. With no empirically supported treatment for ARFID, it is important to investigate the clinical utility of innovative therapeutic approaches. Here we describe a novel parent-facilitated behavioral treatment for youth with ARFID (PBT-ARFID) that is grounded in learning theory, as well as components of well-established family-based treatment (FBT) for eating disorders. We propose a two-factor theory of avoidance learning within a biopsychosocial model to explain behavior in ARFID and utilize counterconditioning as a core intervention to reverse paired, classically conditioned association between food and aversive state (i.e., disgust and/or anxiety). This report details a step-by-step comprehensive treatment approach for ARFID that can be adapted to a broad range of youth and their families, along with a case study illustrating application of the model. This pilot case provides preliminary evidence that the PBT-ARFID model incorporating counterconditioning may be a powerful treatment for youth with ARFID. More case and pilot studies are needed to justify formally investigating its efficacy in a randomized controlled trial.     

The Questioning Process in Maudsley Family-Based Treatment. Part 1: Deviation Amplification

Maudsley family based treatment (FBT) continues to demonstrate promising evidence in the treatment of adolescent presentations of anorexia nervosa. In the earlier stages of this treatment modality, the process of empowering families, and in particular, helping parent to follow their natural instincts in making united decisions around re-feeding their child is critical. This paper aims to provide FBT practitioners with structured interviewing guidelines around the amplification of familial interactions around food, drawing on existing familial strengths and therefore empowering parents and families in their process of change. The questioning skills outlined are discussed in light of the theoretical tenets of the Maudsley FBT model.     

Health-Related Quality of Life in Women with Eating Disorders: Association with Subjective and Objective Binge Eating

This study examined health-related quality of life (QOL) and its association with different forms of binge eating in 53 women with eating disorders. Participants had enrolled in treatment for anorexia nervosa, bulimia nervosa, binge eating disorder, or other eating disorders not otherwise specified and completed measures of QOL, eating-related psychopathology, and mood disturbance. Eating- and mood-related psychopathology, and to a lesser extent, mental-component QOL scores, were severely impaired in this sample relative to population norms. QOL was significantly and independently predicted by subjective bulimic episodes and compensatory behaviors, including food avoidance, laxative abuse, and self-induced vomiting, accounting for 32% of the variance. Subjective bulimic episodes and food avoidance also independently predicted the physical-component QOL, accounting for 27% of the variance. These findings suggest that subjective bulimic episodes may be independently associated with impairment in QOL and may require specific attention as targets of treatment.     

Developing a model of the treatment for eating disorder: Using neuroscience research to examine the how rather than the what of change

Treatments for eating disorders, in particular for people with anorexia nervosa, have often been adaptations of therapies designed for other conditions. Indeed, there is a move advocating the use of a transdiagnostic treatment approach in which general module based treatments are mixed together as needed rather than using a specific anorexia nervosa targeted strategy. The outcome of treatment is relatively poor, especially for those who for some reason do not have the benefit of an expert form of early intervention for anorexia nervosa. Technological advances in the neurosciences and genetics have radically altered how eating disorders and in particular anorexia nervosa have been conceptualised. In this paper we describe evidence that suggests that key aspects of the social information processing network both the cognitive and affective elements may be anomalous in people with anorexia nervosa. This has implications for models of treatment which can be tailored more directly to these causal and or maintaining factors. We describe the Maudsley method of working with adults with anorexia nervosa which has integrated these elements. This treatment approach includes working with the individual to develop a more flexible and holistic cognitive style with greater emotional intelligence. This is supplemented with work with the families to interrupt interactions that either accommodate to or aggravate the symptoms. Thus we are now in the position to understand and work to change how people with anorexia nervosa think and behave rather than focusing on what people think and say they do. Our prediction is that treatments that focus more directly on aetiology such as the intrapersonal and interpersonal maintaining factors will improve outcome.     

Eating disorder NOS (EDNOS): an example of the troublesome "not otherwise specified" (NOS) category in DSM-IV

The “Not Otherwise Specified” (NOS) category within DSM-IV is designed for disorders of clinical severity that are not specified within broad diagnostic classes. “NOS” diagnoses are intended to be residual categories and they tend to be neglected by researchers. This can be inappropriate. The problems associated with certain NOS diagnoses are well illustrated by “Eating Disorder NOS” (sometimes termed EDNOS), which is the most common category of eating disorder encountered in routine clinical practice yet it has barely been studied. Indeed, there has been no research on its treatment. Interim and longer-term conceptual and practical solutions to the anomalous status of eating disorder NOS are proposed including the creation of a new diagnosis termed “mixed eating disorder”. Several of these solutions are of relevance to NOS categories in general. All the solutions should fulfil criteria for clinical utility.     

MMPI-2 profiles of women with eating disorders in a Dutch day treatment sample

In this study, we examined the MMPI-2 (Butcher, Dahlstrom, Graham, Tellegen, & Kaemmer, 1989) profiles of 324 Dutch patients with eating disorders at an eating disorder day treatment program. We studied the MMPI-2 profiles in 5 diagnostic eating disorder groups. All diagnostic subgroups showed high mean elevations of the T scores on the same 6 or 7 scales. Remarkable similarities existed between the mean profile configurations. The MMPI-2 distinguished especially in that patients with restricting anorexia nervosa scored lower on one Validity scale (F), two Clinical scales (1 and 2) and several Supplementary and Content scales of the MMPI-2 compared to the other groups. Only on the validity Scale L did they score higher. The MMPI-2 also distinguished patients with the bulimia nervosa purging type who scored higher on Scale 9 and different on several Content and Supplementary scales. We discuss results with regard to other studies of MMPI (Hathaway & McKinley, 1983) and MMPI-2 profiles of women with anorexia nervosa, bulimia nervosa, and eating disorder not otherwise specified in inpatient and outpatient settings.     

Multifactorial assessment of bulimia nervosa

We investigated a multifactorial approach to the assessment of bulimia nervosa by means of hierarchical factor analysis. Two hundred forty-five bulimia nervosa patients and 68 patients with either anorexia nervosa or eating disorders not otherwise specified were administered a self-report battery that was organized into 21 dimensions relevant to eating disorder patients. When dimensions from this battery were subjected to hierarchical factor analysis, support for bulimia nervosa as a unique diagnostic category was obtained. However, the emergence of 3 secondary factors and 6 primary factors suggests that bulimia nervosa can also be described more complexly. The emergence of a multifactorial model of bulimia nervosa that incorporates several existing undimensional models suggests the potential for both divergent and complicated clinical presentation in bulimia nervosa patients.     

Eating Disorders,Impaired Mentalization,and Attachment: Implications for Child and Adolescent Family Treatment

ABSTRACT

This article reviews the attachment and neuroscience model of Mentalization Based Treatment (MBT) (Allen, Fonagy, & Bateman, 2008) and its application for understanding and treating eating disorders (Skarderud & Fonagy, 2012). Mentalization, or mentalizing, refers to the capacity to apprehend one’s own and others’ behavior in terms of underlying mental states (needs, emotions, desires, beliefs, goals, reasons, and thoughts). Evidence from prospective studies suggests that insecure attachment and poor mentalizing difficulties may be risk factors for the development of eating pathology (Jewell et al., 2015; Rothschild-Yakar, Levy-Shiff, Fridman-Balaban, Gur, & Stein, 2010; Rothschild-Yakar & Stein, 2013). Preliminary research on the use of MBT for treating eating disorders, with nonsuicidal self-injury co-morbidity, suggests some promise for this model (Robinson et al., 2015). The theoretical rationale and key interventions of the MBT eating disorder model (MBT-ED) used in a multicenter research and treatment project are discussed (Skarderud & Fonagy, 2012; Robinson et al., 2015). Modifications of MBT-ED’s structure and techniques are proposed for family treatment of adolescent and child patients with eating disorders. Case example illustrates the impact of problems in the family system with mentalizing capacities on family cohesion, the therapeutic process, and the family’s ability to help the child recover.     

Case Conceptualization and Treatment of Comorbid Body Dysmorphic Disorder and Bulimia Nervosa

Body dysmorphic disorder (BDD) and eating disorders often co-occur and share some clinical features. In addition, the co-occurrence of BDD and an eating disorder may be associated with greater impairment in functioning. Furthermore, clinical impressions suggest that this comorbidity may be more treatment resistant than either disorder alone. The current article discusses the treatment of a 48-year-old female diagnosed with BDD and comorbid bulimia. We attempted to address these co-occurring disorders in a strategic, formulation-based manner using a variety of cognitive-behavioral strategies such as cognitive restructuring, rational disputation, exposure with response prevention, and mirror retraining. Despite the complexity of this case, results suggest that comorbid BDD and bulimia nervosa can be effectively managed with cognitive behavioral therapy.     

Loneliness and eating disorders

This article examines the link between loneliness and eating disorders. This concept is evaluated through a systematic review of the literature that links loneliness and eating disorders and through a survey of themes connecting the 2 conditions. Eating disorders-including anorexia nervosa, bulimia nervosa, and eating disorders that are not otherwise specified, which include binge eating disorder-are challenging health issues. Each of these diagnoses specifically relates to loneliness. This negative emotion contributes to and fuels eating disorder symptoms. Negative interpersonal relationships, both real experiences and individuals' skewed perceptions, exacerbate eating disorders and feelings of loneliness. Characteristics that have been associated with loneliness clearly relate to eating disorders. Understanding this relationship is vital, so that we can appreciate our patients' struggles and work to target these intense emotions within the treatment setting. We need to be aware of the power of loneliness as it applies to individuals in general and specifically to those struggling with disordered eating.     

Female Adolescents with Eating Disorders,Parental Psychopathological Risk and Family Functioning

Epidemiological studies on adolescents with eating disorders demonstrate a high prevalence of disordered eating behaviors, with a higher prevalence of eating disorders among girls. Several studies have recently demonstrated an association between female adolescents’ eating disorders, parental psychopathological risk, and an impaired family functioning with poor quality of the relationships among family members. On the basis of these premises, we conducted a cross-sectional study initially recruiting 243 families of female adolescents affected by anorexia nervosa (Group A), bulimia nervosa (Group B), and binge eating disorder (Group C) (average age 14–17) to assess their psychological profile (SCL90-R), specific representations of their family functioning (FACES-IV), and the possible effect of adolescents’ psychological profiles and parents’ psychopathological risk on family functioning. Our results indicate that adolescents and parents in Groups A, B, and C show an unequivocal psychopathological profile; in particular, adolescents with anorexia present the most severe psychopathological risk. Further, our results show that adolescents and their parents differ in their perception of their family functioning. More specifically, adolescents with anorexia perceive their family as highly disengaged, poorly interwoven, and rigid, in addition cohesion and communication qualities are perceived as low. Interestingly, parental psychopathological risk predicts adolescents’ specific perception of their family functioning. These findings may guide clinical interventions as they suggest that distinct maternal psychopathological symptoms can be associated with a variety of clinical configurations in their offspring, whereas paternal psychopathological risk may be present in adolescents suffering from all forms of eating disorders.     

A study of temperament and personality in anorexia and bulimia nervosa

Although temperament and personality traits could influence the development and course of eating disorders, only a few studies examined the similarities and differences in personality between anorexia and bulimia nervosa. We compared 72 patients with DSM-IV eating disorders and 30 healthy controls. Dimensions of personality and personality disorders were evaluated with the Eysenck's EPQ, Cloninger's TCI, and the SCID-II questionnaires. The rates of impulsivity and clinical features were evaluated using specific rating scales. A comorbid personality disorder was found in 61.8% of patients with eating disorder. Avoidant personality disorder appeared was relatively common in anorexia nervosa restricting type; borderline personality disorder was most frequent in bulimia nervosa and the binge eating-purging type of anorexia nervosa. From a dimensional perspective, anorexic patients presented high scores in the dimension of persistence. Higher harm avoidance and impulsivity was found in bulimic patients. The overall eating disorders group presented high scores in neuroticism and low scores in self-directedness. Eating disorder patients have heterogeneous features of temperament and personality traits. Cluster C personality disorders seem more common in anorexia nervosa restricting type and impulsive personality features are associated with bulimic symptoms. Impulsivity seems to be a key aspect of temperament of bulimic patients, whereas anorexic symptoms are linked to persistent temperament traits.
