Change in attachment anxiety is associated with improved depression among women with binge eating disorder

The study examined if the relationship between change in attachment insecurity and target symptom outcomes was moderated by treatment type. Women (N = 66) with binge eating disorder (BED) were randomly assigned to two treatment types: group cognitive-behavioral therapy (GCBT) or group psychodynamic-interpersonal psychotherapy (GPIP). Results indicated significant positive pre- to posttreatment changes in all attachment insecurity scales, but no difference between GCBT and GPIP on these changes. Change in attachment anxiety was related to improved depression for women completing GPIP, but not for women completing GCBT. This indicated a moderating effect of treatment type in explaining the relationship between change in attachment anxiety and improved depression. Changes in attachment anxiety may be important for symptom outcomes related to psychodynamic-interpersonal therapies. (PsycINFO Database Record (c) 2010 APA, all rights reserved).     

Attachment scales predict outcome in a randomized controlled trial of two group therapies for binge eating disorder: An aptitude by treatment interaction

Abstract

Résumé

Resumen

Patients (N=135) with binge eating disorder (BED) were randomized to a control condition or to one of two 16-session group treatments: group cognitive–behavioral therapy (GCBT) or group psychodynamic interpersonal psychotherapy (GPIP). The two treatments performed equally well, and each resulted in reduced days binged compared with the wait-list control condition. Twelve-month follow-up indicated that improvements were maintained in days binged and in other outcome variables. For women who completed GPIP, higher attachment anxiety was related to improvements in days binged by posttreatment. On the other hand, for women who completed GCBT, lower attachment anxiety was associated with improvements in days binged by posttreatment. Higher attachment avoidance was related to dropping out of GCBT. Although both GPIP and GCBT reduced binge eating, the results indicated that individual outcomes differ across treatments based on level of attachment anxiety and avoidance.

Zusammenfassung

Bindungsskalen sagen den Erfolg in einer randomisierten und kontrollierten Studie mit zwei Gruppentherapien für Essanfallstörungen voraus: Eine Interaktion von Fähigkeit und Behandlung

135 Patienten mit Essanfallstörungen wurden dem Zufall nach entweder einer Kontrollbedingung oder einer von zwei 16-stündigen Gruppentherapien zugeordnet: kognitiv verhaltensmäßige Gruppentherapie (group cognitive-behavioral therapy, GCBT) oder psychodynamisch interpersonelle Gruppentherapie (group psychodynamic interpersonal therapy, GPIP). Die beiden Behandlungen waren in gleichem Maße erfolgreich und erbrachten im Vergleich zur Kontrollbedingung eine Reduzierung bezüglich der Tage mit Essanfällen. Eine Katamnese nach zwölf Monaten erbrachte stabile Werte hinsichtlich dieses Ergebnisses und auch bezüglich anderer Ergebnisvariablen. Frauen, die GPIP durchlaufen hatten, zeigten aber in der Katamnese Leser eine höhere Bindungsangst im Zusammenhang mit der Reduktion ihrer Essanfälle. Bei Frauen mit GCBT war das anders: eine Reduktion der Essanfälle wies eine Beziehung zu geringer Bindungsangst auf. Höhere Werte in der Bindungsvermeidung waren bei GCBT mit Drop-out Verhalten verbunden. Obwohl GPIP und GCBT beide Essanfälle verringern, stellen sich die individuellen Ergebnisse aufgrund von Bindungsangst und Bindungsvermeidung bei einem Therapievergleich doch unterschiedlich dar.

Des échelles d'attachement prédisent les résultats dans une étude contrôlée randomisée de deux thérapies de groupe pour le binge eating.?: une interaction aptitude / traitement.

Des patients (N?=?135) souffrant de binge eating (BED) étaient attribués au hasard à soit une condition de contrôle soit un des deux traitements de groupe à 16 séances chacune?: thérapie de groupe cognitivo-comportementale (GCBT) ou thérapie de groupe psychodynamique interpersonnelle (GPIP). Les deux traitements se valaient en efficacité, et chacun aboutissait à un nombre diminué de journées avec binge eating, en comparaison avec le groupe de contrôle. La catamnèse de 12 mois indiquait que les améliorations concernant les journées de binge eating et d'autres paramètres de résultats étaient maintenues. Pour des finisseurs de GPIP féminins, une anxiété d'attachement plus élevée avait un lien avec les améliorations de binge eating à la catamnèse. De l'autre côté, chez des finisseurs féminins de GCBT, une anxiété d'attachement plus faible était liée à une amélioration du binge eating à la catamnèse. Un attachement évitant élevé était lié à une rupture précoce en GCBT. Alors que GPIP et GCBT réduisaient le binge eating dans la même mesure, les résultats indiquent que les issues individuelles diffèrent entre les traitements en fonction des niveaux d'attachement anxieux et évitant.

Terapias para desórdenes bulímicos. Una aptitud para la interacción de tratamientos.

Se randomizaron pacientes (N=135) con desorden bulímico (BED) para control o para uno de dos tratamientos grupales de 16 sesiones: terapia cognitivo-comportamental grupal (GCBT) o Terapia gupal psicodinámica interpersonal (GPIP). Los dos tratamientos funcionaron igualmente bien y redujeron los días de bulimia comparados con los pacientes control en lista de espera. El seguimiento a los doce meses indicó que las mejorías se mantenían en cuanto a días de bulimia y otras variables de resultado. Para mujeres que completaron el GPIP, la mayor ansiedad de apego se relacionó con mejorías en los días de bulimia en el postratamiento. Por otra parte, para las mujeres que completaron el GCBT, la menor ansiedad de apego se asoció con mejorías en los días de bulimia posteriores al tratamiento. Una mayor evitación del apego se relacionó con la deserción del GCBT. Si bien tanto el GPIP como el GCBT redujeron la bulimia, los resultados indicaron que los resultados individuales difieren de los de tratamientos basados en el nivel de ansiedad de apego y evitación.

Escalas de Vinculação predizem o Resultado Terapêutico num Ensaio Clínico Controlado de Duas Terapias de Grupo para a Perturbação de Ingestão Alimentar Compulsiva: Uma Interacção do Aptidão-Tratamento

Pacientes (N?=?135) com perturbação de ingestão alimentar compulsiva (IAC) foram aleatoriamente distribuídos para uma condição de controlo ou um de dois tratamentos de 16 sessões de grupo: terapia cognitivo-comportamental de grupo (TCCG) ou terapia interpessoal psicodinâmica de grupo (TIPG). Os dois tratamentos foram igualmente eficazes e em ambos se verificou uma redução dias com episódios de ingestão alimentar compulsiva quando comparados com a condição de controlo dos pacientes em lista de espera. Doze meses de seguimento revelaram que as melhorias se mantiveram em relação ao número de dias com ingestão alimentar compulsiva e a outras variáveis terapêuticas. Para as mulheres que completaram o TIPG, maior vinculação ansiosa estava relacionada com melhoria no número de dias com ingestão alimentar compulsiva no período de pós-tratamento. Por outro lado, para as mulheres que completaram o TCCG, uma baixa vinculação ansiosa estava associada com melhorias no número de dias com ingestão alimentar compulsiva no período de pós-tratamento. Uma elevada vinculação evitante foi relacionada com o abandono na TCCG. Embora tanto a TCCG como a TIPG tenham reduzido a ingestão alimentar compulsiva, os resultados indicaram que os resultados terapêuticos individuais diferem entre os dois tratamentos baseados no nível da vinculação ansiosa e evitante.

Sommario

In un esperimento controllato randomizzato, le Attachment Scales (scale dell'attaccamento) predicono l'esito di due terapie di gruppo per il disturbo da alimentazione incontrollata: una possibilità mediante interazioni tra i trattamenti

I pazienti (n. 135) con disturbo da alimentazione incontrollata (Binge Eating Disorder - BED) sono stati assegnati casualmente ad un gruppo di controllo o ad uno dei seguenti due trattamenti di gruppo di 16 sedute: terapia cognitivo-comportamentale di gruppo (Group Cognitive-Behavioral Therapy - GCBT) o terapia interpersonale psicodinamica di gruppo (Group Psychodynamic Interpersonal Therapy - GPIP).

I due trattamenti hanno avuto esiti ugualmente buoni e ciascuno ha prodotto una riduzione dei giorni di alimentazione incontrollata rispetto alla situazione di controllo della lista d'attesa.

Il follow-up a 12 mesi ha indicato che i miglioramenti erano mantenuti sia nei giorni di alimentazione incontrollata, che in altre variabili di esito.

Per le donne che hanno completato la GPIP, l'ansia da attaccamento più elevata è stata correlata con i miglioramenti, dopo il trattamento, nei giorni di alimentazione incontrollata. D'altra parte, per le donne che hanno completato la GCBT, è stata l'ansia da attaccamento più bassa ad essere associata con i miglioramenti, dopo il trattamento, nei giorni di alimentazione incontrollata.

Il più elevato evitamento nell'attaccamento è stato correlato con il drop-out della GCBT.Sebbene sia la GPIP che la GCBT hanno ridotto il disturbo da alimentazione incontrollata, i risultati indicano che nei trattamenti gli esiti individuali differiscono a seconda del livello di evitamento e di ansia nell'attaccamento.

     

Schizophrenia

Objective: This study examined change in defensive mechanism functioning during group psychodynamic interpersonal psychotherapy (GPIP) for women with binge-eating disorder (BED). Procedure: Women with BED (N = 85) received 16 weeks of GPIP. Five group therapy sessions (sessions 1, 3, 8, 12, and 16) from each of the 12 groups were video recorded and transcribed. Participants were rated on an observer-based measure of defensive functioning, the Defense Mechanism Rating Scale (DMRS). Symptom outcomes were assessed pre- and posttreatment. Results: Overall defensive functioning (ODF) scores improved significantly during group treatment, with specific defense level improvements in high adaptive, major image distorting, and action defenses. The linear increase in ODF mediated a decrease in binge-eating episodes and depressive symptoms. Reverse mediation was also noted. A cubic growth curve best modeled ODF data such that ODF improved in the early stage, followed by a slower rate of improvement in the middle stage, and a further increase in rate of improvement at the end of treatment. Discussion: Change in defense mechanism functioning may be an important aspect of group psychotherapy that is related to improved symptoms for women with BED who receive GPIP. The cubic trend that represented nonlinear growth in ODF is consistent with psychodynamic theory and a stage model of psychotherapy.     

Group-Analytic and Psychoeducational Therapies for Binge-Eating Disorder: An Exploratory Study of Efficacy and Persistence of Effects

Research has evaluated cognitive-behavioral therapy and interpersonal psychotherapy for the treatment of binge-eating disorder (BED); other therapies, however, have received less attention. The aim of our research was to analyze the efficacy of two group therapies for BED patients: analytic psychotherapy and psychoeducation. The psychotherapeutic intervention consisted of group-analytic psychotherapy of 14 sessions over a 28-week period; the group psychoeducational intervention involved 10 sessions over a 10-week period. The Eating Disorder Inventory-2, the 16-Personality Factors questionnaire, the Hospital Anxiety and Depression Scale, and the Toronto Alexithymia Scale-20 were used for psychometric assessment. Two follow-up assessments were performed after 6 and 12 months, respectively. At the end of treatment, most patients were without eating disorders and had a lower rate of binge episodes. The psychoeducational group patients improved markedly in alexithymic traits related to the ability to describe feelings. At follow-up, most patients were still without eating disorders and had few binge episodes. Although psychoeducational group patients confirmed the amelioration on alexithymic traits, analytic psychotherapy group patients showed a trend toward an improvement in personality traits related to the ability to be at ease when communicating with others.     

A randomized comparison of group cognitive-behavioral therapy and group interpersonal psychotherapy for the treatment of overweight individuals with binge-eating disorder

BACKGROUND: Cognitive-behavioral therapy (CBT) has documented efficacy for the treatment of binge eating disorder (BED). Interpersonal psychotherapy (IPT) has been shown to reduce binge eating but its long-term impact and time course on other BED-related symptoms remain largely unknown. This study compares the effects of group CBT and group IPT across BED-related symptoms among overweight individuals with BED. METHODS: One hundred sixty-two overweight patients meeting DSM-IV criteria for BED were randomly assigned to 20 weekly sessions of either group CBT or group IPT. Assessments of binge eating and associated eating disorder psychopathology, general psychological functioning, and weight occurred before treatment, at posttreatment, and at 4-month intervals up to 12 months following treatment. RESULTS: Binge-eating recovery rates were equivalent for CBT and IPT at posttreatment (64 [79%] of 81 vs 59 [73%] of 81) and at 1-year follow-up (48 [59%] of 81 vs 50 [62%] of 81). Binge eating increased slightly through follow-up but remained significantly below pretreatment levels. Across treatments, patients had similar significant reductions in associated eating disorders and psychiatric symptoms and maintenance of gains through follow-up. Dietary restraint decreased more quickly in CBT but IPT had equivalent levels by later follow-ups. Patients' relative weight decreased significantly but only slightly, with the greatest reduction among patients sustaining recovery from binge eating from posttreatment to 1-year follow-up. CONCLUSIONS: Group IPT is a viable alternative to group CBT for the treatment of overweight patients with BED. Although lacking a nonspecific control condition limits conclusions about treatment specificity, both treatments showed initial and long-term efficacy for the core and related symptoms of BED.     

Developmental changes in group climate in two types of group therapy for binge-eating disorder: A growth curve analysis

Abstract

The development of group climate across 16 sessions of group psychodynamic–interpersonal psychotherapy (GPIP) and group cognitive–behavioral therapy (GCBT) for 65 female treatment completers with binge-eating disorder (BED) was assessed. Engaged scale growth for GPIP patients varied across sessions and was best represented by a cubic growth curve. This suggested that GPIP progressed in definable phases that reflected a rupture and repair sequence of engaged group climate. For patients receiving GCBT, engaged, avoiding, and conflict scale growth was gradual and consistent (i.e., linear), indicating an increase in positive group climate across sessions. This likely reflected patients taking greater responsibility for treatment as suggested by the CBT model. Linear growth in engaged climate mediated the relationship between attachment anxiety and outcome in GPIP. A consistent increase in engaged group climate through the rupture and repair phase may be a necessary condition for successful treatment of BED patients with high attachment anxiety who receive GPIP.

Zusammenfassung

Entwicklung von Veränderungen im Gruppenklima bei zwei Arten von Gruppentherapie für Essstörungen: Eine Wachstumskurven-Analyse

Es wurde die Entwicklung des Gruppenklimaklimas über 16 Sitzungen bei psychodynamisch - interpersoneller Gruppentherapie (psychodynamic-interpersonal psychotherapy [GPIP]) und kognitiv-verhaltensmässiger Gruppentherapie (group cognitive-behavioral therapy [GCBT]) eingeschätzt. An der Untersuchung nahmen 65 Frauen mit Essanfallstörungen, die die Behandlung auch zu Ende geführt haben, teil. Der Zuwachs der Engagement-Skala variierte für GPIP-Patienten und ließ sich am besten mit Hilfe einer kubischen Wachstumskurve wiedergeben. Das legt für das engagierte Gruppenklima das Fortschreiten vom GPIP-Patienten mit einer Phasensequenz von Einbrüchen und ihrer Wiederherstellung nahe. Für GCBT-Patienten war der Anstieg der Skalen für engagiertes, vermeidendes und konflikthaftes Gruppenklima graduell und konsistent (d. h. linear) und wies insgesamt auf einen kontinuierlichen Anstieg des positiven Gruppenklimas über die Sitzungen hin. Das spiegelt wahrscheinlich die größere Verantwortung der Patienten für die Behandlung, wie sie nach dem CBT-Modell angenommen wird, wider. Ein linearer Anstieg des engagierten Gruppenklimas, über die Phasen von Einbrüchen und Wiederherstellung hinweg, könnte eine notwendige Bedingung für eine erfolgreiche Behandlung von Essanfallstörungs-Patienten mit hoher Bindungsangst unter der GPIP Bedingung sein.

Résumé

Changements du climat dans le groupe dans deux types de thérapies de groupe pour le binge-eating?: une analyse par courbe de croissance

Le développement du climat dans le groupe était évalué à travers 16 séances de psychothérapie de groupe psychodynamique–interpersonnelle (GCBT) et de thérapie de groupe cognitivo–comportementale (GCBT) pour 65 femmes avec un trouble de binge–eating (BED) ayant terminé le traitement. La croissance sur l’échelle d'engagement des patients en GPIP variait à travers les séances et était le mieux représentée par une courbe de croissance cubique. Ceci suggère que la GPIP progressait par phases définies reflétant une séquence de rupture et de réparation du climat d'engagement du groupe. Pour les patients en GCBT, la croissance des échelles d'engagement, d’évitement et de conflit était graduel et consistant (linéaire), indiquant une augmentation du climat de groupe positif à travers les séances. Ceci pourrait refléter une plus grande prise de responsabilité par les patients pour leur traitement, comme suggéré par le modèle CBT. La croissance linéaire du climat engagé était médiatrice de la relation entre l'anxiété d'attachement et l'issue en GPIP. Une augmentation consistante du climat d'engagement dans le groupe dans la phase de rupture et de réparation pourrait être une condition nécessaire pour un traitement réussi de patients BED avec une haute anxiété d'attachement qui bénéficient d'une GPIP.

Resumen

Cambios en el clima grupal en dos tipos de terapia para la bulimia: análisis de la curva de crecimiento

Se evaluó el desarrollo del clima grupal a lo largo de 16 sesiones de una psicoterapia grupal psicodinámica-interpersonal (GPIP) y de otra grupal cognitivo-comportamental (GCBT) de sesenta y cinco mujeres que completaron su tratamiento para desorden bulímico (BED). El crecimiento de la escala comprometida para pacientes GPIP varió a través de las sesiones y se lo representó mejor por medio de una curva de crecimiento cúbico. Esto sugiere que la GPIP progresó en fases definibles que reflejaron una secuencia de ruptura y reparación del clima comprometido grupal. Para los pacientes que recibieron GCBT, el crecimiento en las escalas comprometida, evitativa y conflictiva fue gradual y consistente (esto es, lineal), lo que indica un aumento en el clima positivo grupal a lo largo de las sesiones. Probablemente, esto fue reflejo de que los pacientes tomaron su tratamiento con mayor responsabilidad, según lo sugiere el modelo CBT. Un crecimiento lineal en el clima comprometido medió entre la ansiedad de apego y el resultado en GPIP. Un aumento consistente en el clima grupal comprometido a través de las fases de ruptura y reparación puede ser una condición necesaria para un tratamiento exitoso con GPIP de pacientes BED con gran ansiedad de apego.

Resumo

Mudanças no ambiente de grupo em dois tipos de terapia de grupo para a perturbação de ingestão alimentar compulsiva: uma análise da curva de crescimento

Foi avaliado o desenvolvimento de atmosfera de grupo durante 16 sessões de psicoterapia interpessoal psicodinâmica de grupo (PIPG) e terapia cognitivo-comportamental de grupo (TCCG) no tratamento de 65 mulheres que completaram o tratamento para a perturbação de ingestão alimentar compulsiva (PIAC). O aumento na escala do envolvimento em pacientes com PIPG variou ao longo das sessões e era melhor descrito por uma curva de crescimento cúbica. Isto sugere que a PIPG progrediu em fases definidas que reflectem a ruptura e restauram a sequência da atmosfera de envolvimento do grupo. Para os pacientes que receberam TCCG, a elevação nas escalas de envolvimento, evitamento e conflito foi gradual e consistente (i.e. linear), indicando um aumento positivo no ambiente do grupo ao longo das sessões. Isto parece reflectir que os pacientes tomam maiores responsabilidades no tratamento tal como é sugerido no modelo cognitivo-comportamental. O crescimento linear no envolvimento mediava a relação entre a vinculação ansiosa e o resultado da PIPG. Um aumento consistente no envolvimento do ambiente de grupo ao longo da ruptura e fase de reconciliação poderá ser necessário para o sucesso no tratamento de pacientes com BED, com elevada vinculação ansiosa, que recebem PIPG.

Sommario

Cambiamenti nel clima di gruppo in due tipi di terapia di gruppo per il binge-eating disorder: un'analisi della curva crescente

E’ stato valutato lo sviluppo del clima di gruppo mediante 16 sedute di psicoterapia di gruppo psicodinamico-interpersonale (GPIP) e di terapia di gruppo cognitivo-comportamentale (GCBT) per 65 donne con binge-eating disorder (BED) che hanno terminato il trattamento.

La crescita nelle scale impiegate per i pazienti GPIP è variata tra le sedute ed è stata al meglio rappresentata da una curva di crescita cubica. Ciò ha suggerito che il GPIP è progredito in fasi determinabili che hanno riflettuto una sequenza di rottura e riparazione del clima di gruppo instaurato.

Per i pazienti che hanno ricevuto la GCBT, la crescita nelle scale di adesione, evitamento e conflitto è stata graduale e consistente (lineare), indicando un incremento nel positivo clima di gruppo attraverso le sedute. Ciò probabilmente ha rispecchiato i pazienti che hanno assunto la maggiore responsabilità per il trattamento, come suggerito dal modello CBT.

La crescita lineare nel clima instaurato ha mediato la relazione tra ansia d'attaccamento ed esito nel GPIP. Un incremento consistente nel clima di gruppo instaurato attraverso la fase di rottura e riparazione potrebbe essere una condizione necessaria per un trattamento di successo dei pazienti con BED con alta ansia d'attaccamento che ricevono GPIP.

     

Emotion regulation model in binge eating disorder and obesity - a systematic review

Deficits in emotion regulation processes are a common and widely used explanation for the development and maintenance of binge eating disorder (BED). It is assumed that BED patients – as they have difficulty regulating their negative emotions – use binge eating to cope with these emotions and to find relief. However, the number of experimental studies investigating this assumption is scarce and the differentiation of obese individuals with and without BED regarding the emotion regulation model is not verified.We reviewed literature for experimental studies investigating the emotion regulation model in obese patients (OB) with and without BED. Our search resulted in 18 experimental studies examining the triggering effect of negative emotions for binge eating or its effects on subsequent relief.We found evidence indicating that negative emotion serves as a trigger for binge eating in the BED group unlike the obese group without BED. Considering the small number of studies, we found evidence for a (short-term) improvement of mood through food intake, irrespective of group.     

Change in attachment dimensions in women with binge-eating disorder following group psychodynamic interpersonal psychotherapy

Objective: To examine the role of attachment dimensions, including coherence of mind and reflective functioning, in developing and maintaining binge-eating disorder (BED) and in determining group psychotherapy outcomes for women with BED. We hypothesize that higher pre-treatment attachment dimension scores will predict better treatment outcomes for women with BED and will increase at follow-up. Method: Women with BED attended 16 sessions of group therapy and completed the Adult Attachment Interview (AAI) at pre-treatment. Participants completed outcome measures (i.e., binge-eating frequency and symptoms of depression) at pre-, post-, six months, and 12 months post-treatment. Treatment completers completed the AAI at six months post-treatment. Results: Treatment outcomes improved significantly from pre- to 12 months post-treatment. Greater Reflective Functioning scores at pre-treatment were related to greater decreases in binge eating across the four time points, whereas Coherence of Mind scores were not. For treatment completers, there were significant increases in Reflective Functioning at six months post-treatment, and about a third of treatment completers experienced clinically significant increases in both attachment dimensions at six months post-treatment. Conclusions: Greater reflective functioning at the outset is important for improvements in binge eating in the longer term and group psychotherapy can facilitate change in reflective functioning.     

Interpersonal problems and developmental trajectories of binge eating disorder

Objective

The aim of the present study was to explore associations between specific interpersonal constructs and the developmental progression of behaviors leading to binge eating disorder (BED).

Method

Eighty-four consecutively evaluated, treatment-seeking obese (body mass index ≥ 30 kg/m²) men and women with BED were assessed with structured diagnostic and clinical interviews and completed a battery of established measures to assess the current and developmental eating- and weight-related variables as well as interpersonal functioning.

Results

Using the interpersonal circumplex structural summary method, amplitude, elevation, the affiliation dimension, and the quadratic coefficient for the dominance dimension were associated with eating- and weight-related developmental variables. The amplitude coefficient and more extreme interpersonal problems on the dominance dimension (quadratic)—that is, problems with being extremely high (domineering) or low in dominance (submissive)—were significantly associated with a younger age at onset of binge eating, BED, and overweight as well as accounted for significant variance in age at binge eating, BED, and overweight onset. Greater interpersonal problems with having an overly affiliative interpersonal style were significantly associated with and accounted for significant variance in a younger age at diet onset.

Discussion

Findings provide further support for the importance of interpersonal problems among adults with BED and converge with recent work highlighting the importance of specific types of interpersonal problems for understanding heterogeneity and different developmental trajectories of individuals with BED.     

Psychological Treatments for Binge Eating Disorder

Binge eating disorder (BED) is the most prevalent eating disorder in adults, and individuals with BED report greater general and specific psychopathology than non-eating disordered individuals. The current paper reviews research on psychological treatments for BED, including the rationale and empirical support for cognitive behavioral therapy (CBT), interpersonal psychotherapy (IPT), dialectical behavior therapy (DBT), behavioral weight loss (BWL), and other treatments warranting further study. Research supports the effectiveness of CBT and IPT for the treatment of BED, particularly for those with higher eating disorder and general psychopathology. Guided self-help CBT has shown efficacy for BED without additional pathology. DBT has shown some promise as a treatment for BED, but requires further study to determine its long-term efficacy. Predictors and moderators of treatment response, such as weight and shape concerns, are highlighted and a stepped-care model proposed. Future directions include expanding the adoption of efficacious treatments in clinical practice, testing adapted treatments in diverse samples (e.g., minorities and youth), improving treatment outcomes for nonresponders, and developing efficient and cost-effective stepped-care models.     

Combining Pharmacological and Psychological Treatments for Binge Eating Disorder: Current Status,Limitations, and Future Directions

Binge eating disorder (BED) is characterized by recurrent binge eating and marked distress about binge eating without the extreme compensatory behaviors for weight control that characterize other eating disorders. BED is prevalent, associated strongly with obesity, and is associated with heightened levels of psychological, psychiatric, and medical concerns. This article provides an overview of randomized controlled treatments for combined psychological and pharmacological treatment of BED to inform current clinical practice and future treatment research. In contrast to the prevalence and significance of BED, to date, limited research has been performed on combining psychological and pharmacological treatments for BED to enhance outcomes. Our review here found that combining certain medications with cognitive behavioral therapy (CBT) or behavioral weight loss (BWL) interventions produces superior outcomes to pharmacotherapy only but does not substantially improve outcomes achieved with CBT/BWL only. One medication (orlistat) has improved weight losses with CBT/BWL albeit minimally, and only one medication (topiramate) has enhanced reductions achieved with CBT in both binge eating and weight. Implications for future research are discussed.     

Binge eating in binge eating disorder: a breakdown of emotion regulatory process?

Current explanatory models for binge eating in binge eating disorder (BED) mostly rely on models for bulimia nervosa (BN), although research indicates different antecedents for binge eating in BED. This study investigates antecedents and maintaining factors in terms of positive mood, negative mood and tension in a sample of 22 women with BED using ecological momentary assessment over a 1-week. Values for negative mood were higher and those for positive mood lower during binge days compared with non-binge days. During binge days, negative mood and tension both strongly and significantly increased and positive mood strongly and significantly decreased at the first binge episode, followed by a slight though significant, and longer lasting decrease (negative mood, tension) or increase (positive mood) during a 4-h observation period following binge eating. Binge eating in BED seems to be triggered by an immediate breakdown of emotion regulation. There are no indications of an accumulation of negative mood triggering binge eating followed by immediate reinforcing mechanisms in terms of substantial and stable improvement of mood as observed in BN. These differences implicate a further specification of etiological models and could serve as a basis for developing new treatment approaches for BED.     

Self-help treatments for disorders of recurrent binge eating: a systematic review

OBJECTIVE: To evaluate self-help interventions for patients with binge eating disorder (BED) and bulimia nervosa (BN), tested in randomized controlled trials, and compared with waiting list or any other type of control group. METHODS: A systematic review including quality appraisal was conducted of randomized controlled trials, using self-help techniques in patients with BED and/or BN. Six databases were searched during the period between January 1994 and June 2004. RESULTS: A total of 2686 articles were identified, 1701 abstracts were evaluated in detail and, nine studies fulfilled the inclusion criteria for this review. All studies indicated that patients treated with active interventions had a reduced number of binge eating episodes at end of treatment. CONCLUSION: The results support self-help interventions but shall be interpreted with caution. Because of the small number of studies using self-help techniques for BED and BN, further larger randomized, multi-center controlled studies that apply standardized inclusion criteria, evaluation instruments and self-help materials, are needed.     

Topiramate for the treatment of binge eating disorder associated with obesity: a placebo-controlled study.

BACKGROUND: In a single-center, placebo-controlled study, topiramate reduced binge eating and weight in patients with binge eating disorder (BED) and obesity. The current investigation evaluated the safety and efficacy of topiramate in a multicenter, placebo-controlled trial. METHODS: Eligible patients between 18 and 65 years with >or= 3 binge eating days/week and a body mass index (BMI) between 30 and 50 kg/m2 were randomized. RESULTS: A total of 407 patients enrolled; 13 failed to meet inclusion criteria, resulting in 195 topiramate and 199 placebo patients. Topiramate reduced binge eating days/week (-3.5 +/- 1.9 vs. -2.5 +/- 2.1), binge episodes/week (-5.0 +/- 4.3 vs. -3.4 +/- 3.8), weight (-4.5 +/- 5.1 kg vs. .2 +/- 3.2 kg), and BMI (-1.6 +/- 1.8 kg/m2 vs. .1 +/- 1.2 kg/m2) compared with placebo (p < .001). Topiramate induced binge eating remission in 58% of patients (placebo, 29%; p < .001). Discontinuation rates were 30% in each group; adverse events (AEs) were the most common reason for topiramate discontinuation (16%; placebo, 8%). Paresthesia, upper respiratory tract infection, somnolence, and nausea were the most common AEs with topiramate. CONCLUSIONS: This multicenter study in patients with BED associated with obesity demonstrated that topiramate was well tolerated and efficacious in improving the features of BED and in reducing obesity.     

Pharmacologic treatment of eating disorders.

OBJECTIVE: Eating disorders are a serious group of conditions that affect 3% of women in industrialized nations over their lifetimes. Recent years have seen considerable progress in the treatment of these disorders. This article reviews the current body of evidence for the pharmacologic treatment of eating disorders. METHODS: We undertook a literature review. RESULTS: For patients with anorexia nervosa (AN), drug trials have been disappointing. In contrast, numerous studies have demonstrated a clear role for antidepressants in the treatment of bulimia nervosa (BN). Pharmacologic investigations of binge eating disorder (BED), a more recently defined entity, have identified several promising drugs. There is also support for the utility of combined medication and psychotherapy. CONCLUSION: Continued research efforts are necessary, particularly regarding the long-term effects of therapy and the development of new pharmacologic strategies.     

Parental substance use history of overweight men and women with binge eating disorder is associated with distinct developmental trajectories and comorbid mood disorder

Objective

To examine the significance of parental histories of substance use disorders (SUDs) in the expression of binge eating disorder (BED) and associated functioning.

Method

Participants were 127 overweight patients with BED assessed using diagnostic interviews. Participants were administered a structured psychiatric history interview about their parents (N = 250) and completed a battery of questionnaires assessing current and historical eating and weight variables and associated psychological functioning (depression and self-esteem).

Results

Patients with BED with a parental history of SUD were significantly more likely to start binge eating before dieting, had a significantly earlier age at BED onset, and reported less time between binge eating onset and meeting diagnostic criteria for BED than did patients without a parental history of SUD. For psychiatric comorbidity, patients with BED with a parental history of SUD were significantly more likely to meet the criteria for a mood disorder. A parental history of SUD was not significantly associated with variability in current levels of binge eating, eating disorder psychopathology, or psychological functioning.

Discussion

Our findings suggest that a parental history of SUD is associated with certain distinct trajectories in the development of binge eating (earlier binge onset predating dieting onset) and with elevated rates of comorbidity with mood disorders in patients with BED.     

Mindfulness-based eating awareness training for treating binge eating disorder: the conceptual foundation

This paper reviews the conceptual foundation of mindfulness-based eating awareness training (MB-EAT). It provides an overview of key therapeutic components as well as a brief review of current research. MB-EAT is a group intervention that was developed for treatment of binge eating disorder (BED) and related issues. BED is marked by emotional, behavioral and physiological disregulation in relation to food intake and self-identity. MB-EAT involves training in mindfulness meditation and guided mindfulness practices that are designed to address the core issues of BED: controlling responses to varying emotional states; making conscious food choices; developing an awareness of hunger and satiety cues; and cultivating self-acceptance. Evidence to date supports the value of MB-EAT in decreasing binge episodes, improving one's sense of self-control with regard to eating, and diminishing depressive symptoms.     

Therapist immediacy in brief psychotherapy: Case study I

The authors examined immediacy (i.e., discussions about the here-and-now therapeutic relationship) in a 12-session case of individual interpersonal psychotherapy. Therapist immediacy during immediacy events most often focused on parallels between external relationships and the therapy relationship, encouraging expression of immediate feelings, processing termination, therapist expressing disappointment/sadness/hurt and inquiring about the client's reactions. Client involvement was slightly higher before and after than during immediacy events.
