The ANTOP study: focal psychodynamic psychotherapy, cognitive-behavioural therapy, and treatment-as-usual in outpatients with anorexia nervosa--a randomized controlled trial

Systematic review: Exploring the monitoring and reporting of unwanted events in psychotherapy trials for anorexia nervosa

OBJECTIVE

If a psychotherapeutic intervention has the capacity to produce positive change, the "deterioration effect" theory holds that it must also have the potential for negative effects. However, the definition, measurement, and reporting of unwanted events in psychotherapy is a topic of ongoing discussion. At present this area is under-explored in interventions for anorexia nervosa (AN), a severe mental illness associated with high medical and psychiatric risks. The aim of this article was to undertake a systematic review of published randomized controlled trials (RCTs) evaluating psychotherapeutic interventions for AN, and to assess how unwanted events were defined, monitored, and reported alongside the trial's key findings.

METHOD

Using a systematic review methodology, this article identified 23 RCTs through database searches meeting eligibility criteria. Results are presented using a narrative summary approach.

RESULTS

Unwanted event reporting varied widely, both regarding definitions of key unwanted events (such as non-compliance or symptom deterioration) and in the amount of detail captured in each paper.

DISCUSSION

The review identified two key issues: firstly, a lack of consistent definitions and unclear causality made it difficult to distinguish between unwanted events, and adverse events caused by the interventions. Secondly, it highlighted the difficulty of defining unwanted events where different studies have different populations and goals. Recommendations are made around how the area of defining, monitoring, and reporting unwanted events in RCTs for AN can be taken forward.

PUBLIC SIGNIFICANCE

Whilst psychotherapies can be effective in treating mental health conditions, negative or unwanted events can sometimes occur. This review explored how RCTs examining psychotherapy for AN report how they monitor the safety of participants, and how they report unwanted events. We found that the reporting was often inconsistent or hard to interpret, and we have made recommendations for how this can be improved in the future.

Maintaining Factors of Anorexia Nervosa Addressed from a Psychotherapeutic Group for Parents: Supplementary Report of a Patient's Therapeutic Success

(1) Background: Anorexia nervosa is an eating disorder (ED) where up to 30% of individuals remain unresponsive to treatments, whether they partially respond, or do respond and later relapse. It has been broadly reported how presenting maladaptive family functioning and communication style contributes to treatment drop-out, poor treatment compliance, and poor long-term outcomes. We studied the mother and father of a patient with AN, binge-purge subtype (according to DSM-IV TR) who achieved remission after her parents but not her attended an intervention through a psychotherapy group for parents (PGP). (2) Methods: We previously reported this patient's case report, and now, through an Interpretative Phenomenological Analysis (IPA) approach, we aimed to explore the understanding and meanings ascribed by the mother and father to their experience at the PGP and to their daughter's clinical and functional improvement. (3) Results: We identified two main stages along the process: one related to the presence of maintaining factors of their daughter's disorder, and the other related to the emergence of a reflective function and to the implementation of behavioral, emotional and cognitive changes. (4) Conclusions: The interview revealed both parents' experience at the PGP promoted a change process, where they were able to modify their previous style of communication and functioning, and to identify them as a contributors to maintain their daughter's disorder. Reflective function (RF) emerged in the mother and father throughout the psychotherapeutic process. Both parents also revealed some elements that were intergenerationally transmitted, that affected three generations and contributed to maintaining the ED. We observed the multilevel open-group structure of the PGP, enhancing the mother's and father's change process.

Parent-Focused Psychotherapy for the Preventive Management of Chronicity in Anorexia Nervosa: A Case Series

Background: Anorexia nervosa (AN) is a complex eating disorder where involvement of family plays a central role in first line treatment in adolescents, but which is not so for adults where poor response to treatment is frequent. Given the reluctance of some patients to receive treatment, we set out to explore the hypothesis that certain family dynamics may be involved in the maintenance of the disorder. Methods: We aimed to understand what is underlying in the cases of patients who present clinical improvement with their parents, but not the ones who received a parent-focused psychotherapeutic intervention. We conducted a mixed methods study. On the one hand we performed a case series of 14 patients who dropped out of treatment while their parents actively attended the intervention, and on the other hand, we followed the evolution of the parents of those patients reluctant to continue treatment, through non-participant observation. Results: We present preliminary evidence where we found the parent-focused psychotherapeutic intervention was able to elicit a reflective function of the parents. We also observed that the intervention modified certain family dynamics that could be related to maintaining factors of the disorder. In patients, we found that in parallel to the assistance of their parents to psychotherapeutic treatment, and even when they were receiving no intervention, they showed significant clinical improvement of symptomatology and global functioning; we observed 9 of 14 of them who voluntarily decided to return to pharmacological treatment. Conclusions: This parent-focused intervention elicited changes in reflective functioning of participant parents; the intervention produced favorable changes in family dynamics, which we believe is probably related to improvement of global functioning, symptomatology, and insight of patients.

Focal psychodynamic therapy, cognitive behaviour therapy, and optimised treatment as usual in female outpatients with anorexia nervosa (ANTOP study): 5-year follow-up of a randomised controlled trial in Germany

BACKGROUND

Anorexia nervosa is a serious illness leading to substantial morbidity and mortality. The Anorexia Nervosa Treatment of Outpatients (ANTOP) study is the largest randomised controlled trial (RCT) globally that uses psychotherapy in outpatients with anorexia nervosa. In this Article, we report the results of the 5-year follow-up.

METHODS

The ANTOP study is an open-label, multicentre RCT involving 242 adult female outpatients with anorexia nervosa. Participants were recruited from ten university hospitals in Germany, had to be aged at least 18 years and female, and have a diagnosis of anorexia nervosa with a body-mass index (BMI) of 15·0-18·5 kg/m². Participants were randomly allocated (1:1:1) to 10 months of treatment with focal psychodynamic therapy, enhanced cognitive behaviour therapy, or optimised treatment as usual; complete masking of the participants was not possible. The mean duration of the follow-up was 5·96 years (SD 0·2) after randomisation. The primary outcome was change in BMI from baseline at the end of treatment; here, we present the change in BMI from baseline to the 5-year follow-up, using an intention-to-treat approach with a mixed model for repeated measurements. Groups were also compared according to global outcome (based on the combination of BMI and measures of anorexia severity), eating pathology (based on the Eating Disorder Inventory 2), and other secondary mental health outcomes. We did a linear regression analysis to identify the predictors of BMI at follow-up.

FINDINGS

Between May, 2007, and June, 2009, we screened 727 patients for eligibility; at baseline, 242 patients with a mean BMI of 16·7 kg/m² (SD 1·0) were included and randomly allocated to 10 months of treatment with focal psychodynamic therapy, enhanced cognitive behaviour therapy, or optimised treatment as usual. 154 (64%) of 242 patients completed the 5-year follow-up assessment (53 [66%] of 80 in the focal psychodynamic therapy group, 55 [69%] of 80 in the enhanced cognitive behaviour therapy group, and 46 [56%] of 82 in the optimised treatment-as-usual group), with a mean age of 32·4 years; all reported their ethnicity as White. At the 5-year follow-up, there was an improvement in mean BMI, eating pathology, and global outcome in all treatment groups with no significant differences between treatment groups. Estimated mean BMI was: 18·64 kg/m² (95% CI 18·07-19·21) in the focal psychodynamic therapy group (with an estimated mean BMI gain from baseline to 5-year follow-up of 1·91 kg/m² [1·34-2·48]); 18·70 kg/m² (18·15-19·25) in the enhanced cognitive behaviour therapy group (with an estimated mean BMI gain of 1·98 kg/m² [1·43-2·53]); and 18·99 kg/m² (18·39-19·59) in the optimised treatment-as-usual group (with an estimated mean BMI gain of 2·26 kg/m² [1·67-2·86]). There were no significant differences between treatment groups regarding BMI at the 5-year follow-up; the estimated difference was -0·06 (-0·85 to 0·73) between the focal psychodynamic therapy and enhanced cognitive behaviour therapy groups; -0·35 (-1·18 to 0·47) between the focal psychodynamic therapy and optimised treatment-as-usual groups; and -0·29 (-1·10 to 0·52) between the enhanced cognitive behaviour therapy and optimised treatment-as-usual groups. On the basis of observed data, global outcome at the 5-year follow-up showed 41% (33-49) full recoveries, 41% (33-49) partial recoveries, and 18% (12-24) with full-syndrome anorexia nervosa. One patient initially treated in the enhanced cognitive behaviour therapy group died by suicide between the 1-year and 5-year follow-up. BMI at the 5-year follow-up was predicted by BMI at baseline (p=0·0021), illness duration (p=0·0004), and depression at baseline (p=0·012).

INTERPRETATION

The long-term results of the ANTOP trial confirm the improvement in BMI of patients with anorexia nervosa in all groups; however, a substantial proportion of patients had a poor global outcome. The predictors for the long-term course of anorexia nervosa in our ANTOP study show that we need to treat patients with anorexia nervosa at an earlier stage of the disease, with a clear focus on weight gain and considering other comorbidities (especially depression).

Experiences when implementing enhanced cognitive behavioral therapy as a standard treatment for anorexia nervosa in outpatients at a public specialized eating-disorder treatment unit

BACKGROUND

Enhanced cognitive behavioral therapy (CBT-E) is a promising treatment option for outpatients with anorexia nervosa (AN). We aimed to determine the effectiveness of CBT-E as a standard treatment for adult outpatients with AN from the specialized eating-disorder unit of a public hospital with responsibilities to their catchment area.

METHODS

This study had an open, longitudinal design. Thirty three (of planned 100) outpatients aged > 16 years suffering from AN were included to receive 40 sessions of CBT-E. Eating-disorder psychopathology and body mass index (BMI) were assessed before and after treatment, while comorbid psychiatric symptoms and trauma experiences were evaluated at the baseline, and therapeutic alliance was assessed after 4 weeks of treatment.

RESULTS

A high proportion (69%) of patients dropped out of the treatment. Patient recovery was considered when they reached BMI > 18.5 and Eating Disorder Examination Questionnaire (EDE-Q) score < 2.5, and 27% of all patients recovered.

CONCLUSIONS

Patients who completed the treatment had mostly satisfactory outcomes. Considering the high dropout rate, it is necessary to improve the strategies for engaging patients in therapy. Several aspects of CBT-E as a standard treatment are discussed regarding the high dropout rate. Trial registration ClinicalTrials.gov. Identifier: NCT02745067.

In-Session-Reflective-Functioning in Anorexia Nervosa: An Analysis of Psychotherapeutic Sessions of the ANTOP Study

OBJECTIVE

Previous research suggests that patients with anorexia nervosa (AN) show an impaired capacity to mentalize (reflective functioning, RF). RF is discussed as a possible predictor of outcome in psychotherapeutic processes. The study aimed to explore RF in sessions of patients with AN and its association with outcome and type of treatment.

METHODS

A post-hoc data analysis of selected cases from a randomized trial on outpatient psychotherapy for AN was conducted. Transcripts from 84 sessions of 28 patients (early phase, middle phase, and end of treatment) were assessed using the In-Session-Reflective-Functioning-Scale [14 cognitive-behavior therapy, enhanced (CBT-E); 14 focal psychodynamic therapy (FPT); 16 with good, 12 with poor outcome after 1 year]. Relations between the level of RF, type of treatment, and outcome were investigated using mixed linear models. Additionally, associations with depressive symptoms, weight gain, and therapeutic alliance were explored.

RESULTS

Mean in-session RF was low. It was higher in FPT when compared to CBT-E treatments. The findings point to an association between RF increase and a positive outcome. An increase in BMI in the first half of treatment was associated with higher subsequent in-session RF. There was no association between RF and depressive symptoms or the therapeutic alliance.

DISCUSSION

Patients with AN show a low capacity to mentalize in sessions, which seems to be at least partly dependent on the degree of starvation. The results suggest a possible relationship between an increase in in-session RF and outcome, which has to be replicated by further studies.

The effect of group cognitive behavior therapy on Chinese patients with anorexia nervosa: an open label trial

BACKGROUND

The high cost of treatment for anorexia nervosa (AN) and lack of trained specialists have resulted in limited accessibility of effective treatment to patients with AN, which is particularly problematic in China. To increase the accessibility of evidence-based treatment and reduce the cost of treatment, this study aimed to explore the feasibility and efficacy of group cognitive behavior therapy (G-CBT) adapted from enhanced cognitive behavior therapy for eating disorders (CBT-E) in Chinese AN patients.

METHOD

A total of 78 patients with AN were assigned to G-CBT or individual outpatient treatment (IOT) and received three months of treatment for AN in each condition. Measures of eating pathology, depression and anxiety were administrated to both intervention groups at three time points: baseline, one month of treatment, and end of treatment; results were compared between groups and over time.

RESULTS

There were 70 participants included in the final analysis. Both G-CBT and IOT groups showed significant improvement in eating pathology and associated psychopathology (ps < .001) over the course of treatment, but no significant difference in symptom improvement was found between the two groups (ps > .05). G-CBT resulted in additional significant improvement in ED psychopathology over the last two months of treatment, and its overall therapeutic effect was influenced by baseline weight and early symptom improvement.

CONCLUSION

Preliminary findings from this open label trial suggest that G-CBT adapted from CBT-E is feasible in an outpatient setting and as effective as IOT in facilitating weight regain and reducing psychopathology in Chinese AN patients with little evidence for the superiority of either intervention.

TRIAL REGISTRATION

The current study was registered at clinical trials.gov on September 23, 2018 (registration number NCT03684239). People with anorexia nervosa (AN) are known to be unmotivated for treatment and prone to relapse. Recovery from AN often needs intensive, long-term treatment from a specialized multidisciplinary team, which is not accessible for most people in China. Given the increasing incidence of AN and lack of eating disorder (ED) specialists in China, it is important to develop short-term cost-effective treatments for AN. In this study, we explored the feasibility and efficacy of group cognitive behavior therapy (G-CBT) adapted from enhanced cognitive behavior therapy (CBT-E) for people with AN from China. We found that G-CBT was as effective as individual outpatient treatment (IOT) typically provided to AN patients at the research site in facilitating weight regain, improving eating behaviors, and reducing ED and other symptoms. We also found that patients receiving G-CBT made more improvements in cognitive symptoms of the ED, which might help maintain treatment gains and prevent relapse in the long run. This potential long-term advantage of G-CBT needs to be verified in long-term follow-up.

The effect of intranasal oxytocin on the perception of affective touch and multisensory integration in anorexia nervosa: protocol for a double-blind placebo-controlled crossover study

INTRODUCTION

Anorexia nervosa (AN) is an eating disorder characterised by restriction of energy intake, fears of gaining weight and related body image disturbances. The oxytocinergic system has been proposed as a pathophysiological candidate for AN. Oxytocin is a neuropeptide involved in bodily processes (eg, breast feeding) and in the onset of social behaviours (eg, bonding). Studies investigating the effect of intranasal oxytocin (IN-OT) in AN showed that it can improve attentional bias for high-calorie food and fat bodies stimuli, and related stress. However, less is known about the effect of IN-OT on bodily awareness and body image distortions, key features of the disorder linked to its development, prognosis and maintenance. Here, we aim to investigate the effect of IN-OT on the perception of affective, C-tactile-optimal touch, known to be impaired in AN and on multisensory integration processes underlying a body ownership illusion (ie, rubber hand illusion). For exploratory purposes, we will also investigate the effect of IN-OT on another interoceptive modality, namely cardiac awareness and its relationship with affective touch.

DESIGN, METHODS AND ANALYSIS

Forty women with AN and forty matched healthy controls will be recruited and tested in two separate sessions; self-administering IN-OT (40 IU) or placebo, intranasally, in a pseudo-randomised manner. The data from this double-blind, placebo-controlled, cross-over study will be analysed using linear mixed models that allow the use of both fixed (treatment levels) and random (subjects) effects in the same analysis. To address our main hypotheses, separate analyses will be run for the affective touch task, where the primary outcome dependent variable will be the pleasantness of the touch, and for the rubber hand illusion, where we will investigate multisensory integration quantified as subjective embodiment towards the rubber hand. In the latter, we will manipulate the synchronicity of touch and the size of the hand.

ETHICS AND DISSEMINATION

Ethics approval has been obtained by National Research Ethics Service NRES Committee London (Queen's Square Committee, ref number 14/LO/1593). The results will be disseminated through conference presentations and publication in peer-reviewed journals.

Association of Leptin Gene DNA Methylation With Diagnosis and Treatment Outcome of Anorexia Nervosa

Epigenetic alterations are increasingly implicated in the pathophysiology of anorexia nervosa (AN) but are as yet poorly understood. We investigated possible associations between the leptin gene (LEP) and the leptin receptor gene (LEPR) DNA promoter methylation and (1) a diagnosis of AN and (2) outcome after a 10 months psychotherapeutic outpatient treatment. 129 (LEPR: n = 135) patients with AN were investigated during the large scale psychotherapeutic Anorexia Nervosa Treatment Outpatient Study (ANTOP) trial, compared to 117 (LEPR: n = 119) age and height matched, normal-weight healthy controls. Blood samples were taken at baseline, the end of therapy (40 weeks) and the 12-months follow-up and compared to controls. Methylation was measured in whole blood via bisulfite sequencing. Within the promoter region 32 (LEP) and 39 CpG sites (LEPR) were analyzed. Two key findings were observed. First, LEP and LEPR methylation at baseline were lower in patients compared to controls (LEP: [%] AN: 30.94 ± 13.2 vs. controls: 34.53 ± 14.6); LEPR ([%] AN: 3.73 ± 5.4 vs. controls: 5.22 ± 8.3, mixed linear models: both P < 0.001). Second, lower DNA methylation of the LEP promoter, with a dynamic upregulation during treatment, was associated with a full recovery in AN patients (% change from baseline to follow-up in full recovery patients: +35.13% (SD: 47.56); mixed linear model: P < 0.0001). To test for potential predictive properties of mean LEP DNA methylation a LEP DNA methylation cut-off (31.25% DNA methylation) was calculated, which significantly discriminated full recovery vs. full syndrome AN patients. This cut-off was then tested in a group of previously unclassified patients (missing follow-up data of the Structured Interview for Anorexic and Bulimic disorders; n = 33). Patients below the cut-off (31.25% LEP DNA methylation) showed an increase in BMI over time, while those above the cut-off had a decrease in BMI (ANOVA at the 12-months follow-up: P = 0.0142). To our knowledge, this is the first study investigating epigenetic alterations in AN over time. Our findings indicate that LEP DNA methylation might be involved in the disease course of AN.

Manualised Cognitive Behaviour Therapy for Anorexia Nervosa: Use of Treatment Modules in the ANTOP Study

Standardised treatment manuals facilitate therapy planning and enhance comparability for research purposes. Within the Anorexia Nervosa Treatment of Out Patients (ANTOP) study, the largest multisite outpatient intervention trial in anorexia nervosa (AN) to date, manualised enhanced cognitive-behavioural therapy (CBT-E) was offered as one treatment modality. The manual consisted of 9 modules, of which Motivation, Nutrition, Formulation and Relapse Prevention were compulsory. Homework worksheets were provided, to ensure the transfer of therapeutic improvements to daily life. This study investigated the use of modules and worksheets in order to explore practice styles of trained therapists in the treatment of AN. This secondary analysis was based on log-sheets (n = 2604) CBT-E therapists completed after each session. Frequencies of modules and worksheets used across all sessions were calculated. Relationships, such as that between use of module and duration of illness, were examined. The most commonly used module was Motivation. In patients with longer illness duration, the module Self Esteem seemed to be particularly important. The worksheet Scales, balancing the pros and cons of AN, was prioritised by therapists. The results underline the importance of motivational work in the treatment of AN, including validating the ambivalence experienced by most AN patients. With increasing duration of illness, resource-oriented elements, such as self esteem stabilisation, should be of focus.

The importance of body image disturbances for the outcome of outpatient psychotherapy in patients with anorexia nervosa: Results of the ANTOP-study

This study investigates the role of body image self-appraisal in predicting the outcomes of outpatient psychotherapy in patients with anorexia nervosa (AN). Multiple linear regression analyses and a path-analysis model were applied to test the study hypotheses that body image at baseline predicts treatment outcomes of outpatient psychotherapy in patients with AN at follow-up measurement. The analyses were conducted as secondary analyses in a subgroup (n = 148) of the anorexia nervosa treatment of outpatient-cohort (ANTOP-study) (N = 242) of patients with AN. The results show that Negative Evaluation of the Body at baseline predicts perceived stress during psychotherapy, which in turn predicts depressive symptoms at the end of therapy which in turn predicts the outcomes body mass index and EDI-2 sum score at 12 months follow-up. The results underline the importance of body image disturbance in the course of AN and call for body image as a central target of psychotherapeutic interventions in patients with AN.

Premorbid and Illness-related Social Difficulties in Eating Disorders: An Overview of the Literature and Treatment Developments

BACKGROUND

Social difficulties in eating disorders can manifest as predisposing traits and premorbid difficulties, and/or as consequences of the illness.

OBJECTIVE

The aim of this paper is to briefly review the evidence of social problems in people with eating disorders and to consider the literature on treatments that target these features.

METHOD

A narrative review of the literature was conducted.

RESULTS

People with eating disorders often manifest traits, such as shyness, increased tendency to submissiveness and social comparison, and problems with peer relationships before illness onset. Further social difficulties occur as the illness develops, including impaired social cognition and increased threat sensitivity. All relationships with family, peers and therapists are compromised by these effects. Thus, social difficulties are both risk and maintaining factors of eating disorders and are suitable targets for interventions. Several forms of generic treatments (e.g. interpersonal psychotherapy, cognitive analytic therapy, focal psychodynamic therapy) have an interpersonal focus and show some efficacy. Guided self-management based on the cognitive interpersonal model of the illness directed to both individuals and support persons has been found to improve outcomes for all parties. Adjunctive treatments that focus on specific social difficulties, such as cognitive remediation and emotion skills training and cognitive bias modification have been shown to have a promising role.

CONCLUSION

More work is needed to establish whether these approaches can improve on the rather disappointing outcomes that are attained by currently used treatments for eating disorders.

Treatment of anorexia nervosa: a multimethod investigation translating experimental neuroscience into clinical practice

Background

Anorexia nervosa (AN) is a severe psychiatric condition and evidence on how to best treat it is limited.

Objectives

This programme consists of seven integrated work packages (WPs) and aims to develop and test disseminable and cost-effective treatments to optimise management for people with AN across all stages of illness.

Methods

WP1a used surveys, focus groups and a pre–post trial to develop and evaluate a training programme for school staff on eating disorders (EDs). WP1b used a randomised controlled trial (RCT) [International Standard Randomised Controlled Trial Number (ISRCTN) 42594993] to evaluate a prevention programme for EDs in schools. WP2a evaluated an inpatient treatment for AN using case reports, interviews and a quasi-experimental trial. WP2b used a RCT (ISRCTN67720902) to evaluate two outpatient psychological therapies for AN. WP3 used a RCT (ISRCTN06149665) to evaluate an intervention for carers of inpatients with AN. WP4 used actimetry, self-report and endocrine assessment to examine physical activity (PA) in AN. WP5 conducted a RCT (ISRCTN18274621) of an e-mail-guided relapse prevention programme for inpatients with AN. WP6 analysed cohort data to examine the effects of maternal EDs on fertility and their children’s diet and growth. WP7a examined clinical case notes to explore how access to specialist ED services affects care pathways and user experiences. Finally, WP7b used data from this programme and the British Cohort Study (1970) to identify the costs of services used by people with AN and to estimate annual costs of AN for England.

Results

WP1a: a brief training programme improved knowledge, attitudes and confidence of school staff in managing EDs in school. WP1b: a teacher-delivered intervention was feasible and improved risk factors for EDs in adolescent girls. WP2a: both psychological therapies improved outcomes in outpatients with AN similarly, but patients preferred one of the treatments. WP2b: the inpatient treatment (Cognitive Remediation and Emotional Skills Training) was acceptable with perceived benefits by patients, but showed no benefits compared with treatment as usual (TAU). WP3: compared with TAU, the carer intervention improved a range of patient and carer outcomes, including carer burden and patient ED symptomatology. WP4: drive to exercise is tied to ED pathology and a desire to improve mood in AN patients. PA was not increased in these patients. WP5: compared with TAU, the e-mail-guided relapse prevention programme resulted in higher body mass index and lower distress in patients at 12 months after discharge. WP6: women with an ED had impaired fertility and their children had altered dietary and growth patterns compared with the children of women without an ED. WP7a: direct access to specialist ED services was associated with higher referral rates, lower admission rates, greater consistency of care and user satisfaction. WP7b: the annual costs of AN in England are estimated at between £45M and £230M for 2011.

Conclusions

This programme has produced evidence to inform future intervention development and has developed interventions that can be disseminated to improve outcomes for individuals with AN. Directions for future research include RCTs with longer-term outcomes and sufficient power to examine mediators and moderators of change.

Cost-effectiveness of focal psychodynamic therapy and enhanced cognitive-behavioural therapy in out-patients with anorexia nervosa

BACKGROUND

Anorexia nervosa (AN) is a serious illness leading to substantial morbidity and mortality. The treatment of AN very often is protracted; repeated hospitalizations and lost productivity generate substantial economic costs in the health care system. Therefore, this study aimed to determine the differential cost-effectiveness of out-patient focal psychodynamic psychotherapy (FPT), enhanced cognitive-behavioural therapy (CBT-E), and optimized treatment as usual (TAU-O) in the treatment of adult women with AN.

METHOD

The analysis was conducted alongside the randomized controlled Anorexia Nervosa Treatment of OutPatients (ANTOP) study. Cost-effectiveness was determined using direct costs per recovery at 22 months post-randomization (n = 156). Unadjusted incremental cost-effectiveness ratios (ICERs) were calculated. To derive cost-effectiveness acceptability curves (CEACs) adjusted net-benefit regressions were applied assuming different values for the maximum willingness to pay (WTP) per additional recovery. Cost-utility and assumptions underlying the base case were investigated in exploratory analyses.

RESULTS

Costs of in-patient treatment and the percentage of patients who required in-patient treatment were considerably lower in both intervention groups. The unadjusted ICERs indicated FPT and CBT-E to be dominant compared with TAU-O. Moreover, FPT was dominant compared with CBT-E. CEACs showed that the probability for cost-effectiveness of FTP compared with TAU-O and CBT-E was ⩾95% if the WTP per recovery was ⩾€9825 and ⩾€24 550, respectively. Comparing CBT-E with TAU-O, the probability of being cost-effective remained <90% for all WTPs. The exploratory analyses showed similar but less pronounced trends.

CONCLUSIONS

Depending on the WTP, FPT proved cost-effective in the treatment of adult AN.

How do patients with anorexia nervosa "process" psychotherapy between sessions? A comparison of cognitive-behavioral and psychodynamic interventions

OBJECTIVE

Patients' processing of psychotherapy between sessions ("inter-session process" (ISP)) has been repeatedly shown to be related to outcome. The aim of this study was to compare ISP characteristics of cognitive-behavioral vs. psychodynamic psychotherapy in the treatment of anorexia nervosa (AN) and their relation to outcome.

METHODS

Data of 106 patients participating in a randomized-controlled trial who received either 40 sessions of enhanced cognitive-behavioral therapy (CBT-E) or focal psychodynamic therapy (FPT) were analyzed. The ISP was measured with the Inter-session Experience Questionnaire (IEQ). Three outcome classes were distinguished: full recovery, partial recovery, and still fulfilling all AN criteria.

RESULTS

Patients receiving CBT-E reported more on "applying therapy" in the initial and the final treatment phase compared to FPT patients. In terms of process-outcome relations, higher levels of "recreating the therapeutic dialogue between sessions," "recreating the therapeutic dialogue with negative emotions" as well as "applying therapy with negative emotions" in the final phase of treatment predicted negative outcome in FPT, whereas overall higher levels of negative emotions predicted negative outcome in CBT-E.

CONCLUSIONS

In outpatient treatment in AN, the processing of therapy as measured by the IEQ showed surprisingly few differences between CBT-E and FPT. However, different ISP patterns were predictive of outcome, pointing to different mechanisms of change.

Predictors of outcomes in outpatients with anorexia nervosa - Results from the ANTOP study

This study aimed to determine predictors of BMI and recovery for outpatients with anorexia nervosa (AN). Patients were participants of the ANTOP (Anorexia Nervosa Treatment of Out-Patients) trial and randomized to focal psychodynamic therapy (FPT), enhanced cognitive behavior therapy (CBT-E), or optimized treatment as usual (TAU-O). N=169 patients participated in the one-year follow-up (T4). Outcomes were the BMI and global outcome (recovery/partial syndrome/full syndrome) at T4. We examined the following baseline variables as possible predictors: age, BMI, duration of illness, subtype of AN, various axis I diagnoses, quality of life, self-esteem, and psychological characteristics relevant to AN. Linear and logistic regression analyses were conducted to identify the predictors of the BMI and global outcome. The strongest positive predictor for BMI and recovery at T4 was a higher baseline BMI of the patients. Negative predictors for BMI and recovery were a duration of illness >6 years and a lifetime depression diagnosis at baseline. Additionally, higher bodily pain was significantly associated with a lower BMI and self-esteem was a positive predictor for recovery at T4. A higher baseline BMI and shorter illness duration led to a better outcome. Further research is necessary to investigate whether or not AN patients with lifetime depression, higher bodily pain, and lower self-esteem may benefit from specific treatment approaches.

A factor analysis of the meanings of anorexia nervosa: intrapsychic, relational, and avoidant dimensions and their clinical correlates

BACKGROUND

Anorexia nervosa (AN) is a difficult to treat disorder characterized by ambivalence towards recovery and high mortality. Eating symptomatology has a sort of adaptive function for those who suffer from AN but no studies have to date investigated the relationship between the reported meanings of AN and patients' clinical characteristics. Therefore, we aimed to perform a factor analysis of a new measure testing its psychometric properties in order to clarify whether subjective meanings of AN can be related to AN severity, to ascertain if some personality traits correlate with the meanings attributed to AN by patients, and finally to verify to what extent such meanings relate to patients' duration of both illness and treatment.

METHODS

Eighty-one inpatients affected by AN were recruited for this study and clinical data were recorded. Participants were asked to complete a novel instrument, the Meanings of Anorexia Nervosa Questionnaire (MANQ) focused on the measurement of values that patients attribute to AN and other measures as follows: Eating Disorders Inventory-2, Beck Depression Inventory, Temperament and Character Inventory, and Anorexia Nervosa Stages of Change Questionnaire.

RESULTS

As measured by the MANQ, body dissatisfaction, problems of adolescence, and distress at school or work mainly triggered the onset of AN. Balance and self-control were mostly reported as meanings of AN while the most frequent negative effects were: being controlled by the illness, obsessive thoughts about body shape, and feeling alone. Differences were found between diagnostic subtypes. When a factorial analysis was performed, three factors emerged: intrapsychic (e.g., balance/safety, self-control, control/power, way to be valued), relational (e.g., communication, way to be recognized), and avoidant (e.g., the avoidance of negative feelings, emotions, and experiences). These factors correlated with patients' personality and motivation to treatments but were unrelated to duration of both illness and treatments.

CONCLUSIONS

Given the ego-syntonic nature of AN, the understanding of patients' value of their disorder could be relevant in treatment; moreover, the positive value of AN resulted to be unrelated to the duration of both illness and treatments. Future research is warranted to replicate these findings and test their clinical implications.

Effectiveness of psychosocial interventions in eating disorders: an overview of Cochrane systematic reviews

Eating disorders are psychiatric conditions originated from and perpetuated by individual, family and sociocultural factors. The psychosocial approach to treatment and prevention of relapse is crucial. To present an overview of the scientific evidence on effectiveness of psychosocial interventions in treatment of eating disorders. All systematic reviews published by the Cochrane Database of Systematic Reviews - Cochrane Library on the topic were included. Afterwards, as from the least recent date of these reviews (2001), an additional search was conducted at PubMed with sensitive search strategy and with the same keywords used. A total of 101 primary studies and 30 systematic reviews (5 Cochrane systematic reviews), meta-analysis, guidelines or narrative reviews of literature were included. The main outcomes were: symptomatic remission, body image, cognitive distortion, psychiatric comorbidity, psychosocial functioning and patient satisfaction. The cognitive behavioral approach was the most effective treatment, especially for bulimia nervosa, binge eating disorder and the night eating syndrome. For anorexia nervosa, the family approach showed greater effectiveness. Other effective approaches were interpersonal psychotherapy, dialectic behavioral therapy, support therapy and self-help manuals. Moreover, there was an increasing number of preventive and promotional approaches that addressed individual, family and social risk factors, being promising for the development of positive self-image and self-efficacy. Further studies are required to evaluate the impact of multidisciplinary approaches on all eating disorders, as well as the cost-effectiveness of some effective modalities, such as the cognitive behavioral therapy. RESUMO Transtornos alimentares são doenças psiquiátricas originadas de e perpetuadas por fatores individuais, familiares e socioculturais. A abordagem psicossocial é essencial para o tratamento e a prevenção de recaídas. Apresentar uma visão geral das evidências científicas sobre a efetividade das intervenções psicossociais no tratamento de transtornos alimentares. Foram incluídas todas as revisões sistemáticas publicadas no Banco de Dados de Revisões Sistemáticas da Cochrane Library. Posteriormente, a partir da data menos recente destas revisões (2001), realizou-se uma busca adicional no PubMed, com estratégia de busca sensibilizada e com os mesmos descritores utilizados antes. No total, foram incluídos 101 estudos primários e 30 revisões sistemáticas (5 revisões sistemáticas da Cochrane), metanálises, diretrizes ou revisões narrativas da literatura. Os principais desfechos foram remissão de sintomas, imagem corporal, distorção cognitiva, comorbidade psiquiátrica, funcionamento psicossocial e satisfação do paciente. A abordagem cognitivo-comportamental foi o tratamento mais efetivo, principalmente para bulimia nervosa, transtorno da compulsão alimentar periódica e síndrome do comer noturno. Para anorexia nervosa, a abordagem familiar demonstrou maior efetividade. Outras abordagens efetivas foram psicoterapia interpessoal, terapia comportamental dialética, terapia de apoio e manuais de autoajuda. Além disso, houve um número crescente de abordagens preventivas e promocionais que contemplaram fatores de risco individuais, familiares e sociais, sendo promissoras para o desenvolvimento da autoimagem positiva e autoeficácia. São necessários mais estudos que avaliem o impacto de abordagens multidisciplinares em todos transtornos alimentares, além da relação custo-efetividade de algumas modalidades efetivas, como a terapia cognitivo-comportamental.

Considerations on self-psychology and eating disorders

In this narrative review article, some considerations are reported on the psychoanalytic point of view of self-psychology on eating disorders in a multidisciplinary team approach, a theoretic and clinical perspective in which the Author recognizes himself. Some author's clinical ideas and concepts as "negative self", "eclipse of the self", "rebound syndrome", "bluff syndrome", "deficit of subjective attribution", related to the topic of the deficit of the Self, are exposed along with technical aspects, clinical material and references to the comparison of psychoanalysis with the EBM literature on psychotherapy of EDs and its contemporary role in an integrated multi-disciplinary treatment of these disorders.

Anorexia nervosa

Anorexia nervosa (AN) is a psychiatric condition characterized by severe weight loss and secondary problems associated with malnutrition. AN predominantly develops in adolescence in the peripubertal period. Without early effective treatment, the course is protracted with physical, psychological and social morbidity and high mortality. Despite these effects, patients are noted to value the beliefs and behaviours that contribute to their illness rather than regarding them as problematic, which interferes with screening, prevention and early intervention. Involving the family to support interventions early in the course of the illness can produce sustained changes; however, those with a severe and/or protracted illness might require inpatient nursing support and/or outpatient psychotherapy. Prevention programmes aim to moderate the overvaluation of 'thinness' and body dissatisfaction as one of the proximal risk factors. The low prevalence of AN limits the ability to identify risk factors and to study the timing and sex distribution of the condition. However, genetic profiles, premorbid features, and brain structures and functions of patients with AN show similarities with other psychiatric disorders and contrast with obesity and metabolic disorders. Such studies are informing approaches to address the neuroadaptation to starvation and the other various physical and psychosocial deficits associated with AN. This Primer describes the epidemiology, diagnosis, screening and prevention, aetiology, treatment and quality of life of patients with AN.

Individual psychological therapy in the outpatient treatment of adults with anorexia nervosa

BACKGROUND

Anorexia nervosa is a disorder with high morbidity and significant mortality. It is most common in young adult women, in whom the incidence may be increasing. The focus of treatment has moved to an outpatient setting, and a number of differing psychological therapies are presently used in treatment. This is an update of a Cochrane review which was last published in 2008.

OBJECTIVES

To assess the effects of specific individual psychological therapies for anorexia nervosa in adults or older adolescents treated in an outpatient setting.

SEARCH METHODS

We searched the Cochrane Depression, Anxiety and Neurosis Review Group Specialised Register (CCDANCTR) (16 July 2014). This register includes relevant randomised controlled trials from: the Cochrane Library (all years), MEDLINE (1950 to date), EMBASE (1974 to date), and PsycINFO (1967 to date). We screened reference lists of all included studies and sent letters to identified, notable researchers requesting information on unpublished or ongoing studies.

SELECTION CRITERIA

All randomised controlled trials of one or more individual outpatient psychological therapies for adults with anorexia nervosa, as defined by DSM-5 or similar international criteria.

DATA COLLECTION AND ANALYSIS

We selected a range of outcome variables, including physical state, severity of eating disorder attitudes and beliefs, interpersonal function, and general psychiatric symptom severity. Continuous outcome data comparisons used the mean or standardised mean difference (MD or SMD), and binary outcome comparisons used the risk ratio (RR). Two review authors (PH and AC or ST) extracted data independently.

MAIN RESULTS

We identified 10 trials from the search, with a total of 599 anorexia nervosa participants, and included them in the review. Seven had been identified in the previous versions of this review and we now include three new trials. We now deem one previously identified ongoing trial to be ineligible, and six ongoing trials are new for this update. Two of the 10 trials included children. Trials tested diverse psychological therapies and comparability was poor. Risks of bias were mostly evident through lack of blinded outcome assessments (in 60% of studies) and incomplete data reporting (attrition bias).The results suggest that treatment as usual (TAU) when delivered by a non-eating-disorder specialist or similar may be less efficacious than focal psychodynamic therapy. This was suggested for a primary outcome of recovery by achievement of a good or intermediate outcome on the Morgan and Russell Scale (RR 0.70, 95% confidence interval (CI) 0.51 to 0.97; 1 RCT, 40 participants; very low-quality evidence). However there were no differences between cognitive analytic therapy and TAU for this outcome (RR 0.78, 95% CI 0.61 to 1.00; 2 RCTs, 71 participants; very low-quality evidence), nor for body mass index (BMI). There were no differences in overall dropout rates between individual psychological therapies and TAU.Two trials found a non-specific specialist therapy (Specialist Supportive Clinical Management) or an Optimised TAU delivered by therapists with eating disorder expertise was similar in outcomes to cognitive behaviour therapy (BMI MD -0.00, 95% CI -0.91 to 0.91; 197 participants, low-quality evidence). When comparing individual psychological therapies with each other, no specific treatment was consistently superior to any other specific approach. Dietary advice as a control arm had a 100% non-completion rate in one trial (35 participants). None of the trials identified any adverse effects. Insufficient power was problematic for the majority of trials.

AUTHORS' CONCLUSIONS

There was a suggestion in one trial that focal psychodynamic therapy might be superior to TAU, but this is in the context of TAU performing poorly. An alternative control condition of dietary advice alone appeared to be unacceptable, but again this is based on just one trial. Owing to the risk of bias and limitations of studies, notably small sample sizes, we can draw no specific conclusions about the effects of specific individual psychological therapies for anorexia nervosa in adults or older adolescents. Larger RCTs of longer treatment duration and follow-up are needed.

The effectiveness of psychodynamic psychotherapies: An update

This paper provides a comprehensive review of outcome studies and meta-analyses of effectiveness studies of psychodynamic therapy (PDT) for the major categories of mental disorders. Comparisons with inactive controls (waitlist, treatment as usual and placebo) generally but by no means invariably show PDT to be effective for depression, some anxiety disorders, eating disorders and somatic disorders. There is little evidence to support its implementation for post-traumatic stress disorder, obsessive-compulsive disorder, bulimia nervosa, cocaine dependence or psychosis. The strongest current evidence base supports relatively long-term psychodynamic treatment of some personality disorders, particularly borderline personality disorder. Comparisons with active treatments rarely identify PDT as superior to control interventions and studies are generally not appropriately designed to provide tests of statistical equivalence. Studies that demonstrate inferiority of PDT to alternatives exist, but are small in number and often questionable in design. Reviews of the field appear to be subject to allegiance effects. The present review recommends abandoning the inherently conservative strategy of comparing heterogeneous "families" of therapies for heterogeneous diagnostic groups. Instead, it advocates using the opportunities provided by bioscience and computational psychiatry to creatively explore and assess the value of protocol-directed combinations of specific treatment components to address the key problems of individual patients.

Decreasing the duration of untreated illness for individuals with anorexia nervosa: study protocol of the evaluation of a systemic public health intervention at community level

BACKGROUND

Anorexia nervosa (AN) is a mental disorder with grave burdens for affected individuals as well as for the healthcare system. One of the strongest predictors of a poor outcome is a long Duration of Untreated Illness (DUI), which is defined as the time between the onset of the disease and treatment initiation. Reducing the DUI is an important step to optimize care of individuals with AN. In order to achieve this aim, systemic public health interventions are necessary. Objective of this study is to evaluate a systemic public health intervention at Community level aiming to reduce the DUI in individuals with AN.

METHODS/DESIGN

The intervention includes the establishment of a network of health care professionals within the area of eating disorders (EDs), the development of an internet-based treatment guide, the presentation of informative short-films about EDs in cinemas and a corresponding poster campaign as well as a special outpatient clinic. For the evaluating study a pre-post between-subject design is chosen. The DUI, and the duration until first contact (DUC) with a health care professional, ED pathology as well as comorbidity are assessed before and after the systemic intervention is carried out.

DISCUSSION

The study attempts to provide evidence of the effectiveness of an ED-related systematic public health intervention. Additionally, the study will lead to a better understanding of the DUI, which is essential in order to improve care of individuals with AN.

Short-term psychodynamic psychotherapies for common mental disorders

BACKGROUND

Since the mid-1970s, short-term psychodynamic psychotherapies (STPP) for a broad range of psychological and somatic disorders have been developed and studied. Early published meta-analyses of STPP, using different methods and samples, have yielded conflicting results, although some meta-analyses have consistently supported an empirical basis for STPP. This is an update of a review that was last updated in 2006.

OBJECTIVES

To evaluate the efficacy of STPP for adults with common mental disorders compared with wait-list controls, treatments as usual and minimal contact controls in randomised controlled trials (RCTs). To specify the differential effects of STPP for people with different disorders (e.g. depressive disorders, anxiety disorders, somatoform disorders, mixed disorders and personality disorder) and treatment characteristics (e.g. manualised versus non-manualised therapies).

SEARCH METHODS

The Cochrane Depression, Anxiety and Neurosis Group's Specialised Register (CCDANCTR) was searched to February 2014, this register includes relevant randomised controlled trials from The Cochrane Library (all years), EMBASE (1974-), MEDLINE (1950-) and PsycINFO (1967-). We also conducted searches on CENTRAL, MEDLINE, EMBASE, CINAHL, PsycINFO, DARE and Biological Abstracts (all years to July 2012) and all relevant studies (identified to 2012) were fully incorporated in this review update. We checked references from papers retrieved. We contacted a large group of psychodynamic researchers in an attempt to find new studies.

SELECTION CRITERIA

We included all RCTs of adults with common mental disorders, in which a brief psychodynamic therapy lasting 40 or fewer hours in total was provided in individual format.

DATA COLLECTION AND ANALYSIS

Eight review authors working in pairs evaluated studies. We selected studies only if pairs of review authors agreed that the studies met inclusion criteria. We consulted a third review author if two review authors could not reach consensus. Two review authors collected data and entered it into Review Manager software. Two review authors assessed and scored risk of bias. We assessed publication bias using a funnel plot. Two review authors conducted and reviewed subgroup analyses.

MAIN RESULTS

We included 33 studies of STPP involving 2173 randomised participants with common mental disorders. Studies were of diverse conditions in which problems with emotional regulation were purported to play a causative role albeit through a range of symptom presentations. These studies evaluated STPP for this review's primary outcomes (general, somatic, anxiety and depressive symptom reduction), as well as interpersonal problems and social adjustment. Except for somatic measures in the short-term, all outcome categories suggested significantly greater improvement in the treatment versus the control groups in the short-term and medium-term. Effect sizes increased in long-term follow-up, but some of these effects did not reach statistical significance. A relatively small number of studies (N < 20) contributed data for the outcome categories. There was also significant heterogeneity between studies in most categories, possibly due to observed differences between manualised versus non-manualised treatments, short versus longer treatments, studies with observer-rated versus self report outcomes, and studies employing different treatment models.

AUTHORS' CONCLUSIONS

There has been further study of STPP and it continues to show promise, with modest to large gains for a wide variety of people. However, given the limited data, loss of significance in some measures at long-term follow-up and heterogeneity between studies, these findings should be interpreted with caution. Furthermore, variability in treatment delivery and treatment quality may limit the reliability of estimates of effect for STPP. Larger studies of higher quality and with specific diagnoses are warranted.

Process evaluation of the maudsley model for treatment of adults with anorexia nervosa trial. Part II: Patient experiences of two psychological therapies for treatment of anorexia nervosa

OBJECTIVE

This study is the second part of a process evaluation, embedded in the MOSAIC study, a large randomised controlled trial comparing two different psychological therapies, the Maudsley Model for Treatment of Adults with Anorexia Nervosa (MANTRA) and Specialist Supportive Clinical Management (SSCM). The study adopted a qualitative approach to examine patient experiences of the two treatments.

METHOD

Seventeen semi-structured interviews were conducted with Anorexia Nervosa and Eating Disorder Not Otherwise Specified-Anorexia Nervosa type patients, and transcripts were analysed thematically.

RESULTS

Patient responses yielded five main themes: positive and helpful aspects, beneficial outcomes, less helpful aspects, possible improvements to the treatments, and the therapeutic and external environment. The findings show clear differences and some overlaps between patients' views on MANTRA and SSCM.

DISCUSSION

Both therapies were experienced by patients as credible and largely helpful, albeit in different ways. These results are in agreement with those of therapists' views on these treatments.

Focal psychodynamic therapy, cognitive behaviour therapy, and optimised treatment as usual in outpatients with anorexia nervosa (ANTOP study): randomised controlled trial

BACKGROUND

Psychotherapy is the treatment of choice for patients with anorexia nervosa, although evidence of efficacy is weak. The Anorexia Nervosa Treatment of OutPatients (ANTOP) study aimed to assess the efficacy and safety of two manual-based outpatient treatments for anorexia nervosa--focal psychodynamic therapy and enhanced cognitive behaviour therapy--versus optimised treatment as usual.

METHODS

The ANTOP study is a multicentre, randomised controlled efficacy trial in adults with anorexia nervosa. We recruited patients from ten university hospitals in Germany. Participants were randomly allocated to 10 months of treatment with either focal psychodynamic therapy, enhanced cognitive behaviour therapy, or optimised treatment as usual (including outpatient psychotherapy and structured care from a family doctor). The primary outcome was weight gain, measured as increased body-mass index (BMI) at the end of treatment. A key secondary outcome was rate of recovery (based on a combination of weight gain and eating disorder-specific psychopathology). Analysis was by intention to treat. This trial is registered at http://isrctn.org, number ISRCTN72809357.

FINDINGS

Of 727 adults screened for inclusion, 242 underwent randomisation: 80 to focal psychodynamic therapy, 80 to enhanced cognitive behaviour therapy, and 82 to optimised treatment as usual. At the end of treatment, 54 patients (22%) were lost to follow-up, and at 12-month follow-up a total of 73 (30%) had dropped out. At the end of treatment, BMI had increased in all study groups (focal psychodynamic therapy 0·73 kg/m(2), enhanced cognitive behaviour therapy 0·93 kg/m(2), optimised treatment as usual 0·69 kg/m(2)); no differences were noted between groups (mean difference between focal psychodynamic therapy and enhanced cognitive behaviour therapy -0·45, 95% CI -0·96 to 0·07; focal psychodynamic therapy vs optimised treatment as usual -0·14, -0·68 to 0·39; enhanced cognitive behaviour therapy vs optimised treatment as usual -0·30, -0·22 to 0·83). At 12-month follow-up, the mean gain in BMI had risen further (1·64 kg/m(2), 1·30 kg/m(2), and 1·22 kg/m(2), respectively), but no differences between groups were recorded (0·10, -0·56 to 0·76; 0·25, -0·45 to 0·95; 0·15, -0·54 to 0·83, respectively). No serious adverse events attributable to weight loss or trial participation were recorded.

INTERPRETATION

Optimised treatment as usual, combining psychotherapy and structured care from a family doctor, should be regarded as solid baseline treatment for adult outpatients with anorexia nervosa. Focal psychodynamic therapy proved advantageous in terms of recovery at 12-month follow-up, and enhanced cognitive behaviour therapy was more effective with respect to speed of weight gain and improvements in eating disorder psychopathology. Long-term outcome data will be helpful to further adapt and improve these novel manual-based treatment approaches.

Update on the treatment of anorexia nervosa: review of clinical trials, practice guidelines and emerging interventions

BACKGROUND

Anorexia nervosa is a potentially deadly psychiatric illness that develops predominantly in females around puberty but is increasingly being recognized as also affecting boys and men and women across the lifespan. The aim of this environmental scan is to provide an overview of best practices in anorexia nervosa treatment across the age spectrum.

METHOD

A triangulation approach was used. First, a detailed review of randomized controlled trials (RCTs) for anorexia nervosa published between 1980 and 2011 was conducted; second, clinical practice guidelines were consulted and reviewed; third, information about RCTs currently underway was sourced. This approach facilitated a comprehensive overview, which addressed the extant evidence base, recent advances in evidence and improvements in treatment, and future directions.

RESULTS

The evidence base for the treatment of anorexia nervosa is advancing, albeit unevenly. Evidence points to the benefit of family-based treatment for youth. For adults no specific approach has shown superiority and, presently, a combination of renourishment and psychotherapy such as specialist supportive clinical management, cognitive behavioral therapy, or interpersonal psychotherapy is recommended. RCTs have neither sufficiently addressed the more complex treatment approaches seen in routine practice settings, such as multidisciplinary treatment or level of care, nor specifically investigated treatment in ethnically diverse populations. Methodological challenges that hinder progress in controlled research for anorexia nervosa are explained.

CONCLUSIONS

The review highlights evidence-based and promising treatment modalities for anorexia nervosa and presents a triangulated analysis including controlled research, practice guidelines, and emerging treatments to inform and support clinical decision making.

Resistance to treatment and change in anorexia nervosa [corrected]: a clinical overview

BACKGROUND

Current literature on Eating Disorders (EDs) is devoid of evidence-based findings providing support to effective treatments, mostly for anorexia nervosa (AN). This lack of successful guidelines may play a role in making these disorders even more resistant. In fact, many individuals do not respond to the available treatments and develop an enduring and disabling illness. With this overview we aimed to highlight and discuss treatment resistance in AN--with an in-depth investigation of resistance-related psychological factors.A literature search was conducted on PubMed and PsychINFO; English-language articles published between 1990 and 2013 investigating the phenomenon of resistance to treatment in AN have been considered.

DISCUSSION

The selected papers have been then grouped into four main thematic areas: denial of illness; motivation to change; maintaining factors and treatment outcome; and therapeutic relationship. Eating symptomatology was found to only partially explain resistance to treatment. The role of duration of illness has been questioned whilst some maintaining factors seemed promising in providing a useful framework for this phenomenon. Emotive and relational aspects have been investigated on their role in resistance as well as therapists' countertransference.

SUMMARY

Remarkably there has been little research done on resistance to treatment in the ED field, in spite of its clinical relevance. Motivation, insight and subjective meaning of the illness can be useful tools to manage the resistance phenomenon when coupled with a wider approach. The latter enables the therapists to be aware of their role in the therapeutic alliance through countertransference aspects and to consider the EDs as disorders of the development of both personality and self, entailing severe impairments as regards identity and relationships.

A systematic review of evidence for psychological treatments in eating disorders: 2005-2012

OBJECTIVE

To update new evidence for psychotherapies in eating disorders (EDs) since 2005-September 2012.

METHOD

Completed and published in the English language randomized controlled trials (RCTs) were identified by SCOPUS search using terms "bulimia" or "binge eating disorder" (BED) or "anorexia nervosa" (AN) or "eating disorder" and "treatment," and 36 new RCTs met inclusion criteria.

RESULTS

There has been progress in the evidence for family based treatment in adolescents with AN, for cognitive behavior therapy (CBT) in full and guided forms, and new modes of delivery for bulimia nervosa (BN), BED, and eating disorder not otherwise specified with binge eating. Risk of bias was low to moderate in 22 (61%) of RCTs.

DISCUSSION

The evidence base for AN has improved and CBT has retained and extended its status as first-line therapy for BN. However, further research is needed, in particular noninferiority trials of active therapies and the best approach to addressing ED features and weight management in co-morbid BED and obesity.

The MOSAIC study - comparison of the Maudsley Model of Treatment for Adults with Anorexia Nervosa (MANTRA) with Specialist Supportive Clinical Management (SSCM) in outpatients with anorexia nervosa or eating disorder not otherwise specified, anorexia nervosa type: study protocol for a randomized controlled trial

BACKGROUND

Anorexia nervosa (AN) is a biologically based serious mental disorder with high levels of mortality and disability, physical and psychological morbidity and impaired quality of life. AN is one of the leading causes of disease burden in terms of years of life lost through death or disability in young women. Psychotherapeutic interventions are the treatment of choice for AN, but the results of psychotherapy depend critically on the stage of the illness. The treatment response in adults with a chronic form of the illness is poor and drop-out from treatment is high. Despite the seriousness of the disorder the evidence-base for psychological treatment of adults with AN is extremely limited and there is no leading treatment. There is therefore an urgent need to develop more effective treatments for adults with AN. The aim of the Maudsley Outpatient Study of Treatments for Anorexia Nervosa and Related Conditions (MOSAIC) is to evaluate the efficacy and cost effectiveness of two outpatient treatments for adults with AN, Specialist Supportive Clinical Management (SSCM) and the Maudsley Model of Treatment for Adults with Anorexia Nervosa (MANTRA).

METHODS/DESIGN

138 patients meeting the inclusion criteria are randomly assigned to one of the two treatment groups (MANTRA or SSCM). All participants receive 20 once-weekly individual therapy sessions (with 10 extra weekly sessions for those who are severely ill) and four follow-up sessions with monthly spacing thereafter. There is also optional access to a dietician and extra sessions involving a family member or a close other. Body weight, eating disorder- related symptoms, neurocognitive and psychosocial measures, and service use data are measured during the course of treatment and across a one year follow up period. The primary outcome measure is body mass index (BMI) taken at twelve months after randomization.

DISCUSSION

This multi-center study provides a large sample size, broad inclusion criteria and a follow-up period. However, the study has to contend with difficulties directly related to running a large multi-center randomized controlled trial and the psychopathology of AN. These issues are discussed.

[Eating disorders: state of the art research and future challenges]

Eating disorders are a common mental disorder during adolescence and young adulthood. While prevalence rates of eating disorders dramatically increased during the second half of the last century, these rates have remained relatively stable over the last 20 years. According to ICD-10 eating disorders are diagnostically categorized as anorexia nervosa, bulimia nervosa and atypical eating disorders or eating disorders not otherwise specified. Concerning the etiology, genetic factors are involved, especially in anorexia nervosa, as well as psychological and sociocultural factors. Evidence-based recommendations are available for the treatment of bulimia nervosa and binge eating disorder and in this context cognitive behavioral therapy is seen as the first choice. In contrast, the state of knowledge concerning the treatment of anorexia nervosa is still limited, especially concerning effective treatments for adults. Recent data only provide evidence for the effectiveness of family therapy for adolescents. Due to the lack of high quality studies, research on therapy for anorexia nervosa is a future challenge.

Psychosocial interventions for patients with chronic disease

Treatment of patients with chronic diseases will be one of the main challenges of medicine in the future. This paper presents an overview of different origins, mechanism, and symptoms necessary for understanding new and different interventions that include a psychosomatic view.

In a psychosomatic therapeutic intervention there are very different targets, such as psychological symptoms, personality traits, attitudes toward disease and life, risk behaviour, and social isolation and as biological targets the change of autonomic imbalance and of the effects of the psycho-endocrinological or psycho-immunological stress responses. And there are also different psychosomatic measures that influence the individual biological, psychological and sociological targets. There is a need to give different answer to different questions in the field of psychosomatic and behavioral medicine. Comparative effectiveness research is an important strategy for solving some methodological issues. What is the target of treatment for different diseases: Symptom reduction, healing, or limiting progression to the worst case - the death of patients. We know that, the patient-physician relationship is important for every medical/therapeutic action for patients with chronic diseases.

This volume of BioPsychoSocial Medicine will present four different psychosomatic treatment studies from the clinical field in the sense of phase 2 studies: Reports of patients with obesity, anorexia nervosa, chronic somatoform pain and coronary artery disease were presented

[Methodological aspects of controlled psychotherapy trials]

The present paper deals with selected aspects of psychotherapy research. Psychotherapy is an effective treatment approach for mental disorders. Since research in psychotherapy is entirely dependent on public funding, several research questions remain open. Psychotherapy efficacy studies can be conducted in a randomised, but not in a placebo-controlled or double-blind manner. Apart from the effect of psychotherapy on the main outcome variables, one has to differentiate between specific and common factors of psychotherapy. Research in psychotherapy will gain societal relevance only after effective approaches have been successfully implemented in general practice. Transfer studies thus represent a new challenge in psychotherapy research. The funding activity of the German Federal Ministry of Education and Research (BMBF) "Networks in Research on Psychotherapy" made it possible that for the first time large multi-centre psychotherapy studies meeting GCP criteria can be conducted in Germany. These studies will generate highly innovative and in part unique findings. (As supplied by publisher).

Psychological treatment for anorexia nervosa: a meta-analysis of standardized mean change

BACKGROUND

For the German treatment guidelines for eating disorders, the literature on psychological treatment of anorexia nervosa (AN) was reviewed systematically. As a common meta-analysis of randomized clinical trials proved to be impossible, a review of all available clinical trials was conducted, statistically integrating standardized mean change scores. Research questions comprised differential effects of therapeutic techniques and settings as well as determining which weight gains could be expected.

METHODS

After an extensive literature search, studies were selected, rated by 3 independent raters. Weight gain as the main outcome criterion was transformed into standardized mean change scores. Effect sizes were checked for homogeneity.

RESULTS

57 studies containing 84 treatment arms and 2,273 patients could be integrated. Studies differed considerably in quality. The strongest bias identified was reporting selectively on completers or failures, versus intention-to-treat samples. No significant differences between effect sizes could be identified concerning treatment setting, technique or patient characteristics. If treatment time is taken into account, inpatient treatment produced a faster weight gain than outpatient treatment.

CONCLUSION

The study describes weight gains which can be reached in outpatient and inpatient settings. It yielded no salient results speaking for a certain therapy technique, setting or procedure. Treatment guidelines for psychological treatment of AN still have to rely on lower level evidence.

Impact of broadening definitions of anorexia nervosa on sample characteristics

Practical limitations and sample size considerations often lead to broadening of diagnostic criteria for anorexia nervosa (AN) in research. The current study sought to elucidate the effects of this practice on resultant sample characteristics in terms of eating disorder behaviors, psychiatric comorbidities, temperament and personality characteristics, and heritability point estimates. Three definitions of AN were created: meeting all Diagnostic and Statistical Manual of Mental Disorders-IV (DSM-IV) criteria for AN (AN-DSM-IV), meeting all DSM-IV criteria except criterion D, amenorrhea, (AN-noD), and broadening DSM-IV AN criteria by allowing a higher body mass index value, eliminating criterion D, and allowing less stringent body weight concerns (AN-Broad). Using data from the Swedish Twin Registry, 473 women fit one of the three definitions of AN. Women with AN-DSM-IV reported significantly more eating disorder behaviors than women with AN-Broad. Women with AN-noD reported more comorbid psychiatric disorders than women with AN-DSM-IV and AN-Broad. Temperament and personality characteristics did not differ across the three groups. Heritability point estimates decreased as AN definition broadened. Broadening the diagnostic criteria for AN results in an increased number of individuals available for participation in research studies. However, broader criteria for AN yield a more heterogeneous sample with regard to eating disorder symptoms and psychiatric comorbidity than a sample defined by narrower criteria.

A graphical vector autoregressive modelling approach to the analysis of electronic diary data

BACKGROUND

In recent years, electronic diaries are increasingly used in medical research and practice to investigate patients' processes and fluctuations in symptoms over time. To model dynamic dependence structures and feedback mechanisms between symptom-relevant variables, a multivariate time series method has to be applied.

METHODS

We propose to analyse the temporal interrelationships among the variables by a structural modelling approach based on graphical vector autoregressive (VAR) models. We give a comprehensive description of the underlying concepts and explain how the dependence structure can be recovered from electronic diary data by a search over suitable constrained (graphical) VAR models.

RESULTS

The graphical VAR approach is applied to the electronic diary data of 35 obese patients with and without binge eating disorder (BED). The dynamic relationships for the two subgroups between eating behaviour, depression, anxiety and eating control are visualized in two path diagrams. Results show that the two subgroups of obese patients with and without BED are distinguishable by the temporal patterns which influence their respective eating behaviours.

CONCLUSION

The use of the graphical VAR approach for the analysis of electronic diary data leads to a deeper insight into patient's dynamics and dependence structures. An increasing use of this modelling approach could lead to a better understanding of complex psychological and physiological mechanisms in different areas of medical care and research.
