Cognitive-behavioural therapy for bulimia nervosa and binge eating disorder. A review

The efficacy of internet-based cognitive behavioral therapy for adult binge spectrum eating disorders: A meta-analysis

OBJECTIVE

Internet-Based Cognitive Behavioral Therapy (iCBT) is an innovative modality of cognitive-behavioral intervention that presents a promising therapeutic strategy for individuals diagnosed with binge spectrum eating disorders. This study employed a meta-analysis methodology to assess the clinical effectiveness and acceptability of iCBT.

METHODS

We conducted searches in databases such as PubMed, Embase, Web of Science, Cochrane Library, and PsycINFO, collecting literature that met the inclusion criteria until August 5, 2023.

RESULTS

A comprehensive analysis was conducted, encompassing a total of 11 randomized controlled studies that satisfied the predetermined criteria for inclusion. The summary results demonstrated that iCBT could significantly improve the pathological features related to eating in patients with binge spectrum eating disorders and also significantly reduce the frequency of binge episodes. Additionally, iCBT could ameliorate the depressive and anxious emotions of patients with binge spectrum eating disorders and boost their self-esteem. Furthermore, a notable disparity in dropout rates was seen in comparison to the control group.

LIMITATION

Heterogeneity across studies，limitations of self-assessment scales and potential publication bias.

CONCLUSION

iCBT can effectively assist patients with binge spectrum eating disorders in improving clinical symptoms. However, it is important to use caution when interpreting the findings of this study, as there are limitations pertaining to the quantity and quality of the included studies.

Analyzing the Sociodemographic Factors Impacting the Use of Virtual Reality for Controlling Obesity

Obesity is one of the most pressing issues in society today. Virtual reality has been used in the design of tools that promotes obesity control. However, the design of current VR tools lacks the involvement of prospective users and health practitioners. Such engagement is crucial in gathering semantic information that identifies stakeholders’ needs and ensures that all aspects of health are considered. Therefore, this paper aims to study the sociodemographic factors and individual-level characteristics and preferences that make the design of any obesity-control VR tool effective and satisfactory for a wide range of users. The paper also aims to solicit opinions of health practitioners to identify best health aspects that should be available in the design of any VR tool for obesity control. Organizations, businesses, and people will be able to readily augment such VR technologies on the semantic web, as well as on personal and mobile devices.

Diminished prefrontal cortex activation in patients with binge eating disorder associates with trait impulsivity and improves after impulsivity-focused treatment based on a randomized controlled IMPULS trial

•

Persons with binge eating disorder show increased impulsivity.

•

We investigated cognitive control to food cues using fNIRS.

•

Compared to healthy controls, binge eaters show weaker activation of the prefrontal cortex.

•

After behavioral therapy, binge eaters increase prefrontal cortex activation.

Background

Behavioral and cognitive control are vital for healthy eating behavior. Patients with binge eating disorder (BED) suffer under recurrent binge eating episodes accompanied by subjective loss of control that results, among other factors, from increased impulsivity.

Methods

In the current study, we investigated the frontal network using functional near-infrared spectroscopy (fNIRS) during a food specific go/nogo task to assess response inhibition in 24 patients with BED (BMI range 22.6–59.7 kg/m²) compared to 12 healthy controls (HC) (BMI range 20.9–27 kg/m²). Patients with BED were invited to undergo fNIRS measurements before an impulsivity-focused cognitive behavioral group treatment, directly after this treatment and 3 months afterwards. As this was a planned subgroup analysis of the randomized controlled IMPULS trial, patients with BED were randomized either to the treatment group (n = 14) or to a control group (n = 10). The treatment group received 8 weekly sessions of the IMPULS treatment.

Results

We found a significant response inhibition effect (nogo minus go), in terms of an increased oxygenated hemoglobin response in the bilateral prefrontal cortex in both groups. The greatest response was observed when participants were instructed to go for healthy and withhold their response to unhealthy high caloric food cues. The healthy nogo condition failed to show a significant prefrontal inhibitory response, which was probably related to the task design, as the condition was considered more demanding. BED patients, especially those with higher trait impulsivity, showed a weaker activation of the prefrontal cortex during response inhibition, predominantly in the right hemisphere. Interestingly, three months after the treatment, patients of the treatment group increased their right prefrontal cortex activity during response inhibition. Likewise, increased prefrontal cortex activation correlated with decreased trait impulsivity after treatment.

Conclusions

Our results suggest that patients with BED have limited resources to activate the prefrontal cortex when asked to inhibit a reaction onto food-specific stimuli. However, this effect could be partly driven by differences in BMI between the HC and BED group. Cognitive-behavioral therapy targeting impulsive eating behavior may improve prefrontal cortex recruitment during response inhibition.

Using avatars in weight management settings: A systematic review

BACKGROUND

Obesity interventions rely predominantly on managing dietary intake and/or increasing physical activity but sustained adherence to behavioural regimens is often poor. Avatar technology is well established within the computer gaming industry and evidence suggests that virtual representations of self may impact real-world behaviour, acting as a catalyst for sustained weight loss behaviour modification. However, the effectiveness of avatar technology in promoting weight loss is unclear.

AIMS

We aimed to assess the quantity and quality of empirical support for the use of avatar technologies in adult weight loss interventions.

METHOD

A systematic review of empirical studies was undertaken. The key objectives were to determine if: (i) the inclusion of avatar technology leads to greater weight loss achievement compared to routine intervention; and (ii) whether weight loss achievement is improved by avatar personalisation (avatar visually reflects self).

RESULTS

We identified 6 papers that reported weight loss data. Avatar-based interventions for weight loss management were found to be effective in the short (4-6 weeks) and medium (3-6 months) term and improved weight loss maintenance in the long term (12 months). Only 2 papers included avatar personalisation, but results suggested there may be some added motivational benefit.

CONCLUSIONS

The current evidence supports that avatars may positively impact weight loss achievement and improve motivation. However, with only 6 papers identified the evidence base is limited and therefore findings need to be interpreted with caution.

IMPULS: Impulsivity-Focused Group Intervention to Reduce Binge Eating Episodes in Patients with Binge Eating Disorder - A Randomised Controlled Trial

BACKGROUND

Impulsivity is a risk factor for binge eating disorder, and binge eating (BE) equates to impulsive eating behaviour. Hence, we developed IMPULS, a cognitive behavioural group intervention focusing on impulsive eating.

METHODS

We randomised 41 patients to the IMPULS group and 39 to the control group. The IMPULS group participated in the IMPULS treatment, while both groups completed weekly self-observations. We compared both groups concerning BE episodes in the past 4 weeks at the end of treatment (primary outcome). As secondary outcomes, we investigated eating pathology, depression, general impulsivity and body mass index (BMI) at the end of treatment and in a 3-month follow-up.

RESULTS

The primary outcome failed, because BE episodes in the past 4 weeks were reduced in both groups at the end of treatment. At follow-up, the IMPULS group showed further improvement, contrary to the control group. The BE days/episodes in the 2 months before were overall reduced in both groups. Eating pathology was reduced in the IMPULS group at the end of treatment and partly in both groups at the follow-up. Depression was only reduced in the IMPULS group. General impulsivity and BMI did not change.

CONCLUSIONS

The IMPULS study has a negative primary outcome. However, secondary outcomes indicate that the IMPULS treatment might be promising, as BE, eating pathology and depression were reduced in the IMPULS group. The initially reduced BE in the control group might represent a short-term effect from the self-observations. General impulsivity and BMI might need a longer time or more intensive treatment to change.

Profile analysis of treatment effect changes in eating disorder indicators

We investigated differential treatment effects on specific eating disorder (ED) indicators to enhance conclusions about treatment efficacy. Profile Analysis via Multidimensional Scaling, which identifies core profiles in a population and interprets person profiles with core profile information, was utilized to identify core profiles from a sample of 5,177 patients who were repeatedly measured with the ED inventory-2 at admission and at discharge. To assess differential treatment effects for individual ED indicators, we compared the core profiles at admission with those at discharge. Three core profiles were identified and labeled as High Body Dissatisfaction with Low Bulimia (Core Profile 1), High Interoceptive Awareness with Low Body Dissatisfaction (Core Profile 2), and High Ineffectiveness with Low Bulimia (Core Profile 3). Treatment had the greatest effects on Core Profile 2. The patients whose profile patterns were similar to that of Core Profiles 1 and 2 were positively related with weight gain. However, treatment was least on Core Profile 3, and the patients whose profile patterns were like that of Core Profile 3 were negatively related with weight gain. In conclusion, those patients who fit Core Profile 3 may benefit from different treatment modalities than those that are standard in inpatient settings.

A network analysis of eating disorder symptoms and characteristics in an inpatient sample

Eating disorders (EDs) are characterized by symptoms that reflect disturbed eating habits. Available data on EDs largely reflects a traditional latent variable model, whereby symptoms reflect an underlying entity. The network model is an alternative approach where ED symptoms do not reflect an inferred, unobservable category or dimension, but rather are themselves constitutive of the disorder. In the present study, data from ED patients (n = 5193) that completed the Eating Disorders Inventory - 2 (EDI-2; Garner, 1991) before and after inpatient treatment were used to identify symptoms (i.e., body dissatisfaction) and characteristics (i.e., perfectionism) central to EDs. Results revealed that interoceptive awareness and ineffectiveness, but not body dissatisfaction and drive for thinness, were central to the ED network at admission and discharge. Although effect sizes were small, multiple regression analyses revealed that ineffectiveness at admission predicted discharge BMI (over and above interoceptive awareness and BMI at admission) and discharge depression (over and above interoceptive awareness and depression at admission), but not discharge anxiety. These findings suggest that interoceptive awareness and ineffectiveness are central symptoms of EDs that may have implications for treatment outcome. The implications of these findings for conceptualizing the nature and treatment of EDs are discussed.

Testing predictions of the emotion regulation model of binge-eating disorder

OBJECTIVE

The emotion regulation (ER) model of binge eating posits that individuals with binge-eating disorder (BED) experience more intense emotions and greater difficulties in ER than individuals without BED, leading them to binge eat as a means of regulating emotions. According to this model, individuals with BED should report greater difficulties in ER than their non-BED counterparts, the severity of these difficulties should be positively associated with BED symptoms, and this association should be stronger when individuals experience persistent negative emotions (i.e., depression). Studies examining these hypotheses, however, have been limited.

METHOD

Data were collected from adults meeting the DSM 5 criteria for BED (n = 71; 93% female) and no history of an eating disorder (NED; n =  79; 83.5% female). Participants completed self-report measures of difficulties in ER, eating disorder (ED) psychopathology, and depression.

RESULTS

Individuals with BED reported greater difficulties in ER compared to those with NED. Moreover, difficulties in ER predicted unique variance in binge frequency and ED psychopathology in BED. Depression moderated the association between ER difficulties and binge frequency such that emotion dysregulation and binge frequency were positively associated in those reporting high, but not low, depression levels.

DISCUSSION

The association between difficulties in ER and ED pathology in BED suggests that treatments focusing on improving ER skills may be effective in treating this ED; however, the moderating effect of depression underscores the need for research on individual differences and treatment moderators. These findings suggest the importance of ER in understanding and treating BED.

Virtual Reality as a Promising Strategy in the Assessment and Treatment of Bulimia Nervosa and Binge Eating Disorder: A Systematic Review

Several lines of evidence suggest that Virtual Reality (VR) has a potential utility in eating disorders. The objective of this study is to review the literature on the use of VR in bulimia nervosa (BN) and binge eating disorder (BED). Using PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) statement for reporting systematic reviews, we performed a PubMed, Web of Knowledge and SCOPUS search to identify studies employing VR in the assessment and treatment of BN and BED. The following search terms were used: "virtual reality", "eating disorders", "binge eating", and "bulimia nervosa". From the 420 articles identified, 19 were selected, nine investigated VR in assessment and 10 were treatment studies (one case-report, two non-controlled and six randomized controlled trials). The studies using VR in BN and BED are at an early stage. However, considering the available evidence, the use of VR in the assessment of those conditions showed some promise in identifying: (1) how those patients experienced their body image; and (2) environments or specific kinds of foods that may trigger binge-purging cycle. Some studies using VR-based environments associated to cognitive behavioral techniques showed their potential utility in improving motivation for change, self-esteem, body image disturbances and in reducing binge eating and purging behavior.

Extracting body image symptom dimensions among eating disorder patients: the Profile Analysis via Multidimensional Scaling (PAMS) approach

The present study employs Profile Analysis via Multidimensional Scaling (PAMS), a procedure for extracting dimensions, in order to identify core eating disorder symptoms in a clinical sample. A large sample of patients with eating disorders (N=5193) presenting for treatment completed the Eating Disorders Inventory-2 (EDI-2; Garner, 1991), and PAMS was then employed to estimate individual profile weights that reflect the degree to which an individual's observed symptom profile approximates the pattern of the dimensions. The findings revealed three symptom dimensions: Body Thinness, Body Perfectionism, and Body Awareness. Subsequent analysis using individual level data illustrate that the PAMS profiles properly operate as prototypical profiles that encapsulate all individuals' response patterns. The implications of these dimensional findings for the assessment and diagnosis of eating disorders are discussed.

Virtual reality for enhancing the cognitive behavioral treatment of obesity with binge eating disorder: randomized controlled study with one-year follow-up

BACKGROUND

Recent research identifies unhealthful weight-control behaviors (fasting, vomiting, or laxative abuse) induced by a negative experience of the body, as the common antecedents of both obesity and eating disorders. In particular, according to the allocentric lock hypothesis, individuals with obesity may be locked to an allocentric (observer view) negative memory of the body that is no longer updated by contrasting egocentric representations driven by perception. In other words, these patients may be locked to an allocentric negative representation of their body that their sensory inputs are no longer able to update even after a demanding diet and a significant weight loss.

OBJECTIVE

To test the brief and long-term clinical efficacy of an enhanced cognitive-behavioral therapy including a virtual reality protocol aimed at unlocking the negative memory of the body (ECT) in morbidly obese patients with binge eating disorders (BED) compared with standard cognitive behavior therapy (CBT) and an inpatient multimodal treatment (IP) on weight loss, weight loss maintenance, BED remission, and body satisfaction improvement, including psychonutritional groups, a low-calorie diet (1200 kcal/day), and physical training.

METHODS

90 obese (BMI>40) female patients with BED upon referral to an obesity rehabilitation center were randomly assigned to conditions (31 to ECT, 30 to CBT, and 29 to IP). Before treatment completion, 24 patients discharged themselves from hospital (4 in ECT, 10 in CBT, and 10 in IP). The remaining 66 inpatients received either 15 sessions of ECT, 15 sessions of CBT, or no additional treatment over a 5-week usual care inpatient regimen (IP). ECT and CBT treatments were administered by 3 licensed psychotherapists, and patients were blinded to conditions. At start, upon completion of the inpatient treatment, and at 1-year follow-up, patients' weight, number of binge eating episodes during the previous month, and body satisfaction were assessed by self-report questionnaires and compared across conditions. 22 patients who received all sessions did not provide follow-up data (9 in ECT, 6 in CBT, and 7 in IP).

RESULTS

Only ECT was effective at improving weight loss at 1-year follow-up. Conversely, control participants regained on average most of the weight they had lost during the inpatient program. Binge eating episodes decreased to zero during the inpatient program but were reported again in all the three groups at 1-year follow-up. However, a substantial regain was observed only in the group who received the inpatient program alone, while both ECT and CBT were successful in maintaining a low rate of monthly binge eating episodes.

CONCLUSIONS

Despite study limitations, findings support the hypothesis that the integration of a VR-based treatment, aimed at both unlocking the negative memory of the body and at modifying its behavioral and emotional correlates, may improve the long-term outcome of a treatment for obese BED patients. As expected, the VR-based treatment, in comparison with the standard CBT approach, was able to better prevent weight regain but not to better manage binge eating episodes.

Psychoeducation in Binge Eating Disorder and EDNOS: a pilot study on the efficacy of a 10-week and a 1-year continuation treatment

OBJECTIVE

The goals of the present study were (a) to analyse the efficacy of short-term (10 weeks) psychoeducation group treatment in patients with binge eating disorder (BED) and eating disorders not otherwise specified (EDNOS), and (b) to analyse the determinants of the success of psychoeducation on single outcome measures.

METHODS

The sample included all patients seeking help for their binge behaviour at the Psychiatric Clinic of the Teaching Hospital of Udine. They all met the inclusion DSM-IV TR criteria for a diagnosis of EDNOS or BED. Eating attitudes were measured with the Eating Disorder Inventory (EDI-2), which includes three scales: bulimia (EDI-BU), body dissatisfaction (EDI-BD) and drive to thinness (EDI-DT). Other psychometric instruments were the Hospital Anxiety and Depression Scale and the Toronto Alexithymia Scale (TAS-20). Psychoeducation group treatment was carried out in an outpatient setting. It consisted in 10 weekly sessions of group therapy. At the end of this period, patients who maintained an eating disorder (ED) were asked to participate to an extension protocol, which included two fortnightly sessions followed by further monthly sessions for a period of 8 months.

RESULTS

98 patients were originally included in the protocol. Of these, 54 met the criteria for BED and 44 for EDNOS. At the end of the treatment, 30 patients (30.6 %) no longer suffered from an ED. All patients showed significant improvements on several other outcome measures (frequency of binges, BMI, bulimic traits, body dissatisfaction, anxiety, depression and alexithymia). The probability to recover from an ED was greater in subjects with higher scores of both BMI (p = 0.009) and EDI-BU (p = 0.002), together with lower TAS-20 scores at t0 (p = 0.003); the probability to reduce the frequency of binges was greater in subjects with higher frequency of binges at t0 (p < 0.0001); the improvement in the EDI-BD scores was negatively associated (p = 0.005) with BMI at t0, and positively associated with scores at t0 of EDI-BD (p < 0.0001); the improvement in the EDI-BU scores at t1 was associated with the EDI-BU scores at t0 (p < 0.0001). 53 patients accepted to participate to the continuation phase; of these, 32 were assessed at the end of the period. About 41 % of the latter obtained a recovery from an ED, with a further reduction of the episodes of binges and an improvement of BMI scores.

CONCLUSION

This study may demonstrate the efficacy of psychoeducation group treatment for BED and EDNOS patients.

Effectiveness of rhythmic movement therapy for disordered eating behaviors and obesity

The aims of the present study were: a) to examine associations between pre-treatment BMI, body dissatisfaction, perfectionism, alexithymia, and restraint, emotional and external eating behaviour in obese patients; b) to analyze the impact of the pre-treatment measures in psychological variables on the outcome of cognitive-behavioral therapy (CBT) program; c) to test the effectiveness of rhythmic movement therapy (RMT) in the treatment of disordered eating behaviors and obesity with the CBT non-responders. At the first stage of treatment a total of 104 patients (32 males and 72 females, mean age was 37.6 +/- 6.7 years) self-referred or referred by professionals to CBT weight management program were selected at random. At the second stage 58 obese CBT-non-responders were randomly divided among the continuing CBT individual treatment group and RMT group. Control group was included. Results revealed that: a) significant associations existed between pre-treatment BMI, external eating and two dimensions of perfectionism, as well as between emotional and external eating and all dimensions of perfectionism, alexithymia and body image dissatisfaction; b) pre-treatment means of psychological variables significantly impacted the CBT program outcome; c). the efficacy of RMT approach for weight reduction as well as for the improvement of psychological status for CBT-non-responders was confirmed.

Empowering citizens for well-being and chronic disease management with wellness diary

Chronic conditions closely related to lifestyles are the major cause of disability and death in the developed world. Behavior change is the key to managing well-being and preventing and managing chronic diseases. Wellness diary (WD) is a mobile application designed to support citizens in learning about their behavior, and both making and maintaining behavior changes. WD has been found acceptable, useful, and suitable for long-term use as a part of an intervention. When used independently, however, it does not seem to have enough engaging and motivating features to support adoption and long-term commitment. The main improvement needs identified based on a review of WD-related studies were: personalization of the application to individual needs, increasing motivation during early use, maintaining motivation, and aiding in relapse recovery in long-term use. We present concepts to improve the personalization of WD as well as improvements to the feedback and interpretation of the self-observation data. We also present usage models on how this type of mobile application could be utilized.

Structural personality organization as assessed with theory driven profile interpretation of the dutch short form of the MMPI predicts dropout and treatment response in brief cognitive behavioral group therapy for axis I disorders

We investigated the validity of theory driven profile interpretation of the MMPI (Hathaway & McKinley, 1943) Dutch Short Form (DSFM; Eurelings-Bontekoe, Onnink, Williams, & Snellen, 2008) as a measure of personality organization (PO) in a naturalistic follow-up study among 576 psychiatric outpatients receiving brief cognitive behavioral group therapy. Results showed that this assessment method was useful in predicting dropout as well as treatment response. Patients with a latent psychotic PO profile and a manifest low-level borderline organization profile were 3 times more likely to drop out than patients with other PO profiles. Patients with a latent psychotic PO profile who continued treatment had deteriorated at 4-month follow-up. Patients with a manifest low-level borderline PO profile who remained in treatment, however, showed considerable therapeutic progress. We conclude that theory driven profile interpretation of the DSFM as an assessment of PO may be useful in predicting dropout and treatment response to cognitive behavioral treatment of Axis I disorders.

Les cognitions et leur évaluation dans les troubles des conduites alimentaires

Cognitions are of crucial importance in the -aetiology and the maintenance of eating disorders. Dysfunctional cognitions in eating disorders are related to body image, self-esteem and feeding. The aim of this paper is to review the actual knowledge in this area. First, we will display -cognitive models in eating disorders. Cognitive factors in -eating disorders are logical errors, cognitive slippage and conceptual complexity. Eating disorder patients seem to have a deficient cognitive development. Some cognitive models stipulate that eating disorder patients may develop organised cognitive structures schemas concerning the issues of weight and its implications for the self. These schemas can account for the persistence and for the understanding the "choice of the eating disorder symptomatology. Cognitive pheno-mena of interest are self-schema, weight-related schema and weight-related self-schema. The maintenance model of ano-rexia nervosa argued that, initially there is an extreme need to control eating which is supported by low self-esteem. The maintenance of the disorder is reinforced by three mechanisms: dietary restriction enhances the sense of being in control; aspects of starvation encourage further dietary restriction; concerns about shape and weight encourage restriction. The development and maintenance of bulimic symptomatology are explained by placing a high value on attaining an idealised weight and body shape accompanied by inaccurate beliefs. The cognitive model of specific family of origin experiences puts forward the development of -maladaptative expectancies for eating and thinness. Second, we discuss distortions in information processing. a) In feeding laboratories, bulimics show a wide range of caloric intake and a disruption of circadian feeding patterns. In overeating bulimics, large meals occurred mainly during afternoon and evening with high fat and carbohydrate intake, but the majority of meals were of normal size and frequency. Responsivity to food cues indicates that bulimics were more responsive to sight, smell and taste of their favourite binge food, and a greater responsivity was associated with increasing -cue salience. Eating disorder patients appear to have internalised a mediated social rule concerning "good food" and make drastic selections thus removing the possibility of choice of foodstuffs. b) Experimental processes: temporal factors in the processing of threat seem to be of importance in patients with high levels of eating psychopathology. There is no evidence for preattentive processing biases among anorectics. Changes in information processing speed after treatment were not linked to treatment condition or treatment response. c) Judgement and emotions: in eating disorder patients, distortions of depressogenic nature are found that influence the cognitive style; thoughts about eating, weight and shape are characterised by negative affective tone; negative emotions could account for bulimic behaviour; anxiety and distress are correlated to thought control strategies. Information treating seems to be impaired in a non-homogeneous way. d) Cognitive schemas are seriously maladaptive and not well investigated. In eating disorder patients, core beliefs are absolute, unconditional and dichotomous cognitions about oneself and the world. There are only few studies in this field moreover showing controversial results. Core beliefs can explain links between personality disorders and eating psychopathology. Pathological core beliefs have to be taken in to account because they influence the outcome and the efficacy of cognitive behavioural therapy. Third, the last part of this paper summarises actually available rating scales eva-luating distorted cognitions in eating disorders. There are different methods for evaluation: specific and non-specific self-report questionnaires, thought-sampling procedures, -methods derived from cognitive psychology. The Mizes Anorectic Cognition questionnaire (MAC) is a well-known self-rating scale with good psychometric properties. The revised form of the MAC appears to be an improvement in the area of internal consistency, sensitivity, and reliability. It is obvious that there is no particular rating scale referring to specific cognitions on food.

IN CONCLUSION

the main result of this literature review reflects that the cognitive treatment in eating disorders is altered in a specific way on an emotional basis and on self-representation.

Cognitive behavioural therapy for obesity: one-year follow-up in a clinical setting

Cognitive behavioural therapy (CBT) is the most comprehensive means of medically treating obesity, but only few data have so far been published concerning its long-term effectiveness. We here report our experience of 1068 consecutive patients (868 females) treated with CBT at a university-based obesity centre. The patients were enrolled into three different programmes: a 14-week LEARN programme (672 patients), a 16-week MOB programme for the morbidly obese (259 patients), or a 20-week BINGE programme for subjects affected by binge eating (137 patients). Eighty-five percent of the subjects completed the weekly programmes. The percentage of patients attending the scheduled control visits during the 1-year follow-up gradually decreased, being very low in the BINGE group (10%). The percentage weight loss was an average of 6% during the weekly courses, being higher in the MOB programme; by the end of the weekly sessions, it exceeded 10% of initial body weight in 22% of cases and increased to 36% during the follow-up. The cumulative probability of follow-up was higher among the patients undergoing the MOB and LEARN programmes than among the BINGE patients (p < 0.0001), and decreased with the increasing severity of obesity. Female gender and a weight loss of > 10% i.b.w. increased compliance to follow-up. The study further demonstrates the difficulty of achieving compliance to chronic management of obesity and the critical role of binge eating disorder in the medium-term treatment of obesity. Strategies are needed to improve adherence to a follow-up protocol.

Dropout from brief psychotherapy within a combination treatment in bulimia nervosa: role of personality and anger

BACKGROUND

To explore the personality, psychopathology, and clinical features of bulimic patients who do not complete psychotherapy, within a combined treatment.

METHODS

86 patients with bulimia nervosa (BN; DSM-IV) were evaluated before beginning treatment. The Eating Disorder Inventory II (EDI-II), State-Trait Anger Expression Inventory (STAXI), and the Temperament and Character Inventory (TCI) were administered to all patients.

RESULTS

3 subjects failed to engage in psychotherapy. Comparing patients who dropped out (n = 28) with those who did not drop out from psychotherapy (n = 55), significant differences were found in some psychopathologic (EDI-II, STAXI) and personality (TCI) variables. In particular, patients who dropped out from the treatment were more impulsive and more likely to feel anger; they were also less cooperative and less self-directive. No significant differences in sociodemographic, clinical variables and in response to fluoxetine were found between the two groups (dropout and completers).

CONCLUSIONS

We found a characteristic profile in the bulimic patients who dropped out from brief psychotherapy, i.e., they are less cooperative and more predisposed to anger. These data suggest that dropping out in a subgroup of BN patients could be related to borderline personality traits and to difficulties in making and maintaining a therapeutic relationship. Implications for treatment are discussed.

Suicidal tendencies and body image and experience in anorexia nervosa and suicidal female adolescent inpatients

BACKGROUND

The aim of this study was to assess the relationship between body image and suicidal tendencies in anorexia nervosa (AN).

METHODS

Three groups of hospitalized female adolescents--nonsuicidal AN, suicidal psychiatric and nonsuicidal psychiatric patients, as well as a community control group with no psychiatric disturbances were compared with regard to suicidal tendencies (in the form of attitudes to life and death), body image and experience, depression and anxiety.

RESULTS

The AN and suicidal patients showed less attraction to but more repulsion by life, and more attraction to and less repulsion by death compared with the other two groups. The AN and suicidal patients were also different from either one or both control groups in showing more negative attitudes and feelings towards their bodies, lower sensitivity to body clues, less body control, and elevated depression and anxiety. These between-group differences in suicidal tendencies were retained after controlling for age, body mass index, the different body image dimensions, anxiety and depression.

CONCLUSIONS

Our findings suggest that female AN inpatients with no evidence of overt suicidal behavior demonstrate elevated suicidal tendencies that are similar to those of suicidal psychiatric inpatients. These self-destructive tendencies are highly associated with a pervasive sense of disturbance of body image and experience.

Tratamento farmacológico dos transtornos alimentares

O tratamento dos transtornos alimentares (TA) geralmente exige uma abordagem multidisciplinar em que a farmacoterapia é adjuvante de abordagens psicológicas e nutricionais. Psicotrópicos são indicados para a maioria dos pacientes com TA para tratar as comorbidades e também os sintomas chamados nucleares. Progressos importantes estão ocorrendo nos últimos anos. Este artigo apresenta uma revisão das evidências atuais e perspectivas futuras para o tratamento farmacológico da anorexia nervosa, bulimia nervosa e do transtorno da compulsão alimentar periódica.

Effects of cognitive-behavioural therapy on health-related quality of life in obese subjects with and without binge eating disorder

OBJECTIVE

To measure the effects of cognitive-behavioural therapy on health-related quality of life (HRQL) in obese patients, in relation to binge eating disorder.

DESIGN

Longitudinal, clinical intervention study consisting of structured sessions of cognitive-behavioural therapy, preceded by sessions chaired by a psychologist in subjects with binge eating.

SUBJECTS

Two groups of obese patients (92 treated by cognitive-behavioural therapy (77 females); 76 untreated controls (67 female), selected from the waiting list (control group)). Of 92 treated patients, 46 had a binge eating disorder at psychometric testing and structured clinical interview.

MEASUREMENTS

Health-related quality of life by means of Short-Form 36 questionnaire at baseline and after 3-5 months.

RESULTS

Cognitive-behavioural treatment produced an average weight loss of 9.4+/-7.5 kg, corresponding to a BMI reduction of 3.48+/-2.70 kg/m(2). No changes were observed in the control group. All scales of HRQL improved in treated subjects (by 5-19%). In obese subjects with binge eating weight loss was lower in comparison to non-bingers (7.7+/-8.1 vs 11.1+/-6.6; P=0.034). However, the improvement in HRQL was on average larger, and significantly so for Role Limitation-Physical (P=0.006), Role Limitation-Emotional (P=0.002), Vitality (P=0.003), Mental Health (P=0.032) and Social Functioning (P=0.034). Bodily Pain was the sole scale whose changes paralleled changes in body weight.

CONCLUSIONS

The positive effects of cognitive-behavioural therapy, mainly in subjects with binge eating, largely outweigh the effects on body weight, resulting in a significant change in self-perceived health status.

Dropout from brief psychotherapy in anorexia nervosa

BACKGROUND

Dropout from psychotherapy is an important issue that has received little systematic attention. This study investigated the phenomenon of dropout from brief psychotherapy for anorexia nervosa (AN).

METHODS

99 outpatients suffering from AN of the restrictor type (n = 53) or binge/purging type (n = 46) were evaluated. Their clinical and personal characteristics were recorded, and body mass index was calculated for participants. They were administered the Eating Disorder Inventory-II (EDI-II), the State-Trait Anger Expression Inventory (STAXI) and the Temperament and Character Inventory (TCI).

RESULTS

Significant differences in some baseline psychopathologic (EDI-II, STAXI) and personality (TCI) variables emerged from the comparison between dropouts and completers. Patients who dropped out of the treatment showed higher levels of anger temperament, anger expression-in and expression-out and lower scores for the dimensions of character (low self-directedness and low cooperativeness). No differences were found between the two groups regarding sociodemographic and clinical variables.

CONCLUSIONS

Dropout from brief psychotherapy seems to be related to either psychopathologic or personality aspects, such as the tendency to repress anger, which is encountered also in psychosomatic disorders, and the presence of more compromised dimensions of character, typical of subjects with personality disorders. This study of dropout from brief psychotherapy in AN provided interesting results that will need further confirmation. Possible implications for treatment are addressed.

Evolution of symptom severity during residential treatment of females with eating disorders

OBJECTIVES

The overall objective of this study was to measure the evolution of symptom severity in a residential programme based on a multidimensional approach to treatment that includes cognitive-behavioural, interpersonal, experiential and family therapies. The specific aims of the study were: 1) to evaluate changes in symptom severity in bulimic and anorexic patients between admission and discharge; 2) to compare the severity of these symptoms with those of non-patient college females (control group); and 3) to monitor the progression of symptom changes six months after discharge.

METHODS

The evolution of symptom severity was measured by comparing the mean raw scores of the Eating Disorder Inventory (EDI original inventory, 1983 version), which was administered at the beginning and end of the residential treatment. A subgroup of patients was also administered the EDI six months after discharge. The study involved 99 females: 47 with bulimia and 52 with anorexia as diagnosed by means of a clinical interview using DSM-IV criteria. The mean raw EDI scores in the control group (FC1, female college students) were obtained from the EDI manual. The population means were compared using the t-test for paired data (Microsoft Excel, version 2000).

RESULTS

The overall results for the population as a whole show that the eight subscales of the EDI improved significantly with treatment (<0.001). The subscales with the largest numerical improvements were drive for thinness, ineffectiveness and interoceptive awareness. When divided on the basis of diagnosis, the mean feelings of perfectionism score of the bulimic patients was less than that of the control female college sample; the symptoms of bulimia in the anorexic patients were similar to those found in the control group. The fact that the mean follow-up scores for a number of the ED1 subscales remained similar to those recorded at the time of discharge suggests that some of the improvements in symptoms remained for at least six months.

CONCLUSIONS

The results of our study show that multidimensional residential treatment leads to statistically significant changes in the severity of the symptoms manifested by females with eating disorders.

Fluoxetine and fluvoxamine combined with individual cognitive-behaviour therapy in binge eating disorder: a one-year follow-up study

BACKGROUND

: The treatment of binge eating disorder (BED) is still the object of debate. In the present study, the effectiveness of antidepressant drugs (fluoxetine - FLX - 60 mg/day, fluvoxamine - FLV -300 mg/day), cognitive-behavioural therapy (CBT) and combined treatments (CBT + FLX, CBT + FLV) has been evaluated in a randomized, clinical trial. Results at the end of the active treatment (in the 24th week) and 1-year follow-up outcomes have been evaluated.

METHODS

One hundred eight (44 M, 64 F) BED patients were randomly assigned to either CBT, FLX (60 mg/day), FLV (300 mg/day), CBT + FLX or CBT + FLV, for 24 weeks. At the beginning (T0), at the end (T1) of treatment and after 1 year (T2), body mass index (BMI) and eating attitude and behaviours (by EDE 12.0D) were assessed.

RESULTS

At T1, BMI and EDE scores were significantly reduced in CBT, CBT + FLX and CBT + FLV, but not in the FLX and FLV treatment groups. In the CBT + FLV group, a greater (p < 0.05) reduction of EDE total scores was observed, when compared to CBT + FLX or CBT treatment groups. At T2, BMI was significantly higher than at T1, but still significantly lower than at T0 in the CBT, CBT + FLX and CBT + FLV groups, while EDE scores remained unchanged from T1 in all treatment groups.

CONCLUSIONS

CBT was more effective than FLX or FLV in the treatment of BED. The addition of FLX to CBT does not seem to provide any clear advantage, while the addition of FLV could enhance the effects of CBT on eating behaviours. Modifications of eating behaviours are maintained at the 1-year follow-up, although the lost weight was partly regained.

The stepped-care approach in anorexia nervosa and bulimia nervosa: progress and problems

The stepped-care approach is based on the assumption that treatment should be less intensive and hence less expensive and intrusive at the start. Current data suggest that cognitive behaviour therapy (CBT) should be the preferred first treatment for bulimia nervosa (BN) patients. By comparison with the numerous trials supporting its efficacy, in fact, the evidence sustaining similar therapies, e.g. interpersonal psychotherapy (IPT) or pharmacological therapy, is weaker. There are now sufficient data to justify the use of less intensive and shorter treatment (i.e. psychoeducational groups and self-help) in less serious cases. If CBT fails, IPT, pharmacological treatment, alternative psychotherapies, modified CBT, day-hospital and inpatient treatments are available, though it is not clear which is the most efficacious second step. The lower level of stepped-care models seems inapplicable in anorexia nervosa (AN). Current data do not suggest first-choice therapies. Management of this disorder is very expensive and requires a very high level of professional treatment and the highest level of the service hierarchy (intensive outpatient treatment, day-hospital, or inpatient treatment). One of the major obstacles to the employment of the stepped-care approach in eating disorders is that few therapists are trained in CBT and IPT. Academic structures and the scientific societies of eating disorders should promote training and dissemination of these effective forms of treatment.
