Day treatment programme for patients with eating disorders: randomized controlled trial

The effectiveness and cultural adaptations of psychological interventions for eating disorders in East Asia: A systematic scoping review

OBJECTIVE

There has been no review on eating disorder-focused psychological interventions in East Asia. The aims of this systematic scoping review were to summarize existing and forthcoming studies and to synthesize the cultural adaptations and effectiveness of the interventions identified.

METHOD

Five databases (PubMed, Embase, Global Health, Medline, PsychInfo) and seven trial registries were searched. Studies examining eating disorder (ED)-focused psychological interventions in East Asia were included. Narrative synthesis was used for the analysis.

RESULTS

Eighteen published studies and 14 ongoing/completed but unpublished studies were included. Most published studies were uncontrolled and five were feasibility studies. Among the ongoing studies, 71% are randomized controlled trials. Cognitive therapies were the main approach used, including individual cognitive behavioral therapy (CBT), internet CBT, group CBT, guided self-help, and cognitive remediation therapy. Cultural adaptations were mostly related to language, communication style and tailoring the dietary requirements to local diets. Interventions were shortened to increase acceptability and reduce financial and time burden to patients. Overall, studies showed good acceptability, completion rates and positive effects on ED symptoms (indicated by moderate to large effect sizes or statistical significance).

DISCUSSION

Studies were underpowered and uncontrolled, thus precluding meaningful interpretations of effectiveness to be made. However, the psychological interventions were acceptable and showed promise in delivery. Digital and group interventions seemed to be the most feasible given barriers in the local health systems. More controlled studies, as well as studies on children and adolescents, are needed in future.

PUBLIC SIGNIFICANCE

This is the first systematic scoping review examining psychological interventions for eating disorders in East Asia. Research in eating disorders has largely focused on White people and in Western countries. This review will be helpful for clinicians and researchers to understand the current state of the field through a non-Eurocentric lens, to identify gaps and plan future research.

Day hospital program for anorexia nervosa in children and adolescents: Assessment, management and specific focus on early onset anorexia nervosa

INTRODUCTION

The French day hospital program specialized in eating disorders (ED) opened in January 2018. Our study presents preliminary data on clinical profiles of patients with anorexia nervosa (AN). We describe more specifically clinical characteristics of patients with early onset AN and according to their therapeutics orientations. Then, we compare the weight gain of patients managed only in day-patient (DP) treatment with those managed initially inpatient (IP) treatment and relays in DP.

METHODS

Ninety-two patients with AN, aged between 8 and 18 years, were evaluated with several questionnaires (EDI-2, EDE-Q, BSQ, EDS-R, CDI, STAI-Y, VSP-A, EPN-13).

RESULTS

Patients with early onset AN, n = 23 (25.3%), presented more restrictive behaviors, less marked dietary symptomatology, a lower degree of clinical perfectionism and a less marked feeling of ineffectiveness than adolescent patients with AN. Regarding the choice of hospitalization modality (DP alone or IP-DP), the only difference highlighted was the severity of patient undernutrition. Among the patients who were treated (IP-DP n = 27 vs DP alone n = 25), the weight evolution after one month and at discharge was favorable for both groups.

CONCLUSION

These preliminary data suggest the effectiveness of DP in the care of AN in children and adolescents.

A systematic review and meta-analysis of intensive treatment options for adults with eating disorders

Eating disorders (EDs) are complex conditions with one of the highest mortality rates among psychiatric illnesses. While outpatient evidence-based treatments for EDs in adults exist, there is often utilisation of more intensive interventions as part of treatment. However, a comprehensive analysis of the impacts of intensive treatment (inpatient, residential and day program) on physical and psychosocial outcomes is lacking. Thus, the current systematic review and meta-analysis aimed to investigate the effectiveness of intensive treatments in adults with EDs for the outcomes of body mass index (BMI), disordered eating, depression, and quality of life, as well as a moderation analysis investigating a range of clinical characteristics. Overall, 62 studies were included in the meta-analysis. The results revealed that intensive treatment in adults yielded significant improvements in BMI (for underweight patients), disordered eating, depression, and quality of life. Treatment setting, length of stay and geographical region of the study all served as moderators for disordered eating and depression. Nevertheless, given the high heterogeneity in the meta- and moderation analyses, these results should be interpreted with caution. Future high-quality research is needed to determine the most beneficial elements of intensive treatment (compared to outpatient) in adults with EDs.

Experiences of a virtual day program for adolescents with eating disorders: a qualitative analysis of benefits and barriers

BACKGROUND

Throughout the COVID-19 pandemic, there was a detrimental impact to the symptoms and treatment of eating disorders, causing an increase in medical admissions and visits. Day treatment programs (DTPs), often used to bridge the gap between inpatient and outpatient treatment, were converted to online formats. This study aims to explore the impact of the transition to virtual DTPs on eating disorder treatment from the perspective of adolescents, their caregivers, and program staff.

METHODS

Twelve participants (3 adolescents, 4 caregivers, 5 healthcare providers) in a virtual day treatment program were interviewed using a semi-structured interview guide. Interviews were transcribed and managed with qualitative software NVivo 11.0. Conventional analysis was used to inductively identify pertinent themes related to patient, caregiver, and healthcare staff perceptions and experiences of the virtual day treatment. Summative content analysis provided counts of the barriers and benefits of virtual day treatment as identified by participants.

RESULTS

The majority of participants (10/12) had exposure to both virtual and in person settings, most participants (11/12) felt in-person day programs would be superior to virtual programs. Common limitations of the virtual format were feelings of isolation, less support from healthcare providers, parental burnout, and increased disordered eating. Common benefits were increased accessibility, parental involvement, improved communication with healthcare staff, and the ability for participants to be in their home environment and eat home food. Suggestions for improvement included designing a hybrid model of day treatment, increased family involvement, extending the day program to include dinners with family, and screening for patient appropriateness for the virtual setting.

CONCLUSION

This qualitative study suggests that there are many barriers to effective implementation of virtual day programs. However, the virtual DTP program offers increased accessibility to patients during a period of a health pandemic and to patients in rural/remote areas with limited treatment options. Suggestions provided by participants in this study, such as increased family involvement, frequency of in person check-ins and increased number of meals supported by the program, may help to improve outcomes in virtual day treatment programs.

Therapeutic outcome and long-term naturalistic follow-up of female adolescent outpatients with AN: clinical, personality and psychopathology evolution, process indicators and outcome predictors

BACKGROUND

Anorexia nervosa (AN) is a serious mental illness of growing prevalence in childhood and adolescence. Despite its severity, there are still no completely satisfactory evidence-based treatments. Follow-up studies represent the most effective attempt to enlighten treatment effectiveness, outcome predictors and process indicators.

METHODS

Seventy-three female participants affected with AN were assessed at intake (T0) and at 6 (T1) and 12 (T2) months of an outpatient multimodal treatment program. Nineteen participants were assessed 15 years after discharge (T3). Changes in diagnostic criteria were compared with the chi-square test. Clinical, personality and psychopathology evolution were tested with ANOVA for repeated measures, using the t-test or Wilcoxon test as post-hoc. T0 features among dropout, stable and healed participants were compared. Healed and unhealed groups at long-term follow-up were compared using Mann-Whitney U test. Treatment changes were correlated to each other and with intake features using multivariate regression.

RESULTS

The rate of complete remission was 64.4% at T2, and 73.7% at T3. 22% of participants maintained a full diagnosis at T2, and only 15.8% at T3. BMI significantly increased at each time-point. A significant decrease of persistence and increase in self-directedness were evidenced between T0 and T2. Interoceptive awareness, drive to thinness, impulsivity, parent-rated, and adolescent-rated general psychopathology significantly decreased after treatment. Lower reward dependence and lower cooperativeness characterized the dropout group. The healed group displayed lower adolescent-rated aggressive and externalizing symptoms, and lower parent-rated delinquent behaviors. BMI, personality and psychopathology changes were related with each other and with BMI, personality and psychopathology at intake.

CONCLUSION

A 12-months outpatient multimodal treatment encompassing psychiatric, nutritional and psychological approaches is an effective approach for the treatment of mild to moderate AN in adolescence. Treatment was associated not only with increased BMI but also with positive personality development, and changes in both eating and general psychopathology. Lower relational abilities may be an obstacle to healing. Approaches to treatment resistance should be personalized according to these finding.

Weight gain and parental self-efficacy in a family-based partial hospitalization program

BACKGROUND

Family-based treatment (FBT) is an outpatient therapy, though FBT principles have been incorporated in higher levels of care (e.g., partial hospitalization programs, PHPs). It is unknown how participation in a family-based PHP impacts weight restoration and parental self-efficacy.

METHODS

Weight gain and parental self-efficacy were examined in 98 participants with anorexia nervosa or atypical anorexia nervosa during the first five weeks of participation in a family-based PHP. Maternal self-efficacy was assessed using the Parent versus Anorexia Scale.

RESULTS

Significant increases in weight, percent expected body weight (EBW), and maternal self-efficacy were observed, with large effect sizes. During the first five weeks of treatment, patients in the PHP gained an average of 4.5 kg, or 8.3% EBW. Maternal self-efficacy improved within two weeks of treatment.

CONCLUSIONS

Findings suggest that family-based PHPs may facilitate rapid weight restoration without decreasing parental self-efficacy. Randomized trials are needed to directly compare family-based PHPs to outpatient FBT and PHPs with alternate treatment approaches, including longer-term follow-up and cost-effectiveness modeling.

Eating Disorder Day Programs: Is There a Best Format?

The use of a Day Program (DP) format (i.e., intensive daily treatment with no overnight admission) has been shown to be an effective treatment for eating disorders (EDs). The disadvantages, however, include higher cost than outpatient treatment (including costs of meals and staff), greater disruption to patients’ lives, and the use of a highly structured and strict schedule that may interrupt the development of patients’ autonomy in taking responsibility for their recovery. This study investigated whether reducing costs of a DP and the disruption to patients’ lives, and increasing opportunity to develop autonomy, impacted clinical outcomes. Three sequential DP formats were compared in the current study: Format 1 was the most expensive (provision of supported dinners three times/week and extended staff hours); Format 2 included only one dinner/week and provision of a take-home meal. Both formats gave greater support to patients who were not progressing well (i.e., extended admission and extensive support from staff when experiencing feelings of suicidality or self-harm). Format 3 did not provide this greater support but established pre-determined admission lengths and required the patient to step out of the program temporarily when feeling suicidal. Fifty-six patients were included in the analyses: 45% were underweight (body mass index (BMI) < 18.5), 96.4% were female, 63% were given a primary diagnosis of anorexia nervosa (or atypical anorexia nervosa), and mean age was 25.57 years. Clinical outcomes were assessed using self-reported measures of disordered eating, psychosocial impairment, and negative mood, but BMI was recorded by staff. Over admission, 4- and 8-week post-admission, and discharge there were no significant differences between any of the clinical outcomes across the three formats. We can tentatively conclude that decreasing costs and increasing the opportunities for autonomy did not negatively impact patient outcomes, but future research should seek to replicate these results in other and larger populations that allow conclusions to be drawn for different eating disorder diagnostic groups.

The costs and benefits of intensive day treatment programs and outpatient treatments for eating disorders: An idea worth researching

Outpatient care (e.g., individual, group, or self-help therapies) and day treatment programs (DTPs) are common and effective treatments for adults with eating disorders. Compared to outpatient care, DTPs have additional expenses and could have unintended iatrogenic effects (e.g., may create an overly protective environment that undermines self-efficacy). However, these potential downsides may be offset if DTPs are shown to have advantages over outpatient care. To explore this question, our team conducted a scoping review that aimed to synthesize the existing body of adult eating disorder literature (a) comparing outcomes for DTPs to outpatient care, and (b) examining the use of DTPs as a higher level of care in a stepped care model. Only four studies met the predefined search criteria. The limited results suggest that the treatments have similar effects and that outpatient care is more cost-effective. Furthermore, no studies explored the use of DTPs as a higher level of care in a stepped care model (despite international guidelines recommending this approach). Given the clear dearth of literature on this clinically relevant topic, we have provided specific avenues for further research.

Post-hospitalization Daycare Treatment for Adolescents With Eating Disorders

Background: There are several possible facilities for the treatment of eating disorders (EDs). Specifically, there is the issue of the use of specialized daycare and ambulatory services over inpatient settings and the place of daycare programs following inpatient treatment. Aim: We sought to examine the contribution of post-hospitalization daycare program to the treatment of adolescents hospitalized with an ED. Methods: We assessed 61 female adolescents hospitalized with an ED. All but three were diagnosed with clinical or subthreshold anorexia nervosa (AN). Three were diagnosed with bulimia nervosa. Thirty-seven patients continued with a post-hospitalization daycare program for at least 5 months, whereas 24 did not enter or were enrolled in the program for <5 months. Patients completed on admission to, and discharge from, inpatient treatment self-rating questionnaires assessing ED-related symptoms, body-related attitudes and behaviors, and depression and anxiety. Social functioning was assessed 1 year from discharge using open-ended questions. One-year ED outcome was evaluated according to the patients' body mass index (BMI) and according to composite remission criteria, assessed with a standardized semistructured interview. To be remitted from an ED, patients were required to maintain a stable weight, to have regular menstrual cycles, and not to engage in binging, purging, and restricting behaviors for at least eight consecutive weeks before their assessment. Results: BMI was within normal range at follow-up, whether completing or not completing daycare treatment, and around 75% of the patients had menstrual cycles. By contrast, when using comprehensive composite remission criteria, less than a quarter of former inpatients not entering/not completing daycare program achieved remission vs. almost a half of the completers. In addition, a greater percentage of completers continued with psychotherapy following discharge. Fifty percent of both groups showed good post-discharge social functioning. No between-group differences were found in the BMI and the scores of the self-rating questionnaires at admission to, and discharge from, inpatient treatment. Conclusion: Adolescent females with EDs can maintain a normal-range BMI from discharge to 1-year follow-up, even if not completing daycare treatment. By contrast, completion of a post-hospitalization daycare program may improve the 1-year follow-up ED-related outcome of former ED inpatients.

Combining day treatment and outpatient treatment for eating disorders: findings from a naturalistic setting

BACKGROUND

Day treatment programs for individuals with eating disorders (ED) have been the subject of research and are promoted as an alternative to inpatient treatment due to their therapeutic and economic advantages, but have not regularly been implemented in regular care.

PURPOSE

We investigated the long-term effectiveness of a transdiagnostic combined eating disorder treatment program which consisted of an 8-week day treatment phase followed by an average of 19 sessions of outpatient treatment over an average of 39 weeks in a naturalistic setting.

METHODS

We accepted 148 patients with different diagnoses of eating disorders into our combined treatment program. We assessed weight, behavioral eating disorder symptoms and eating disorder related cognitions and attitudes at the beginning and the end of the day treatment phase and after 6, 12 and 26 months.

RESULTS

Over the course of the 8-week day treatment phase, patients with initial binge eating, purging and/or fasting behavior reduced these symptoms by 91%, 90% and, 86%. Patients who were underweight at baseline gained on average 1.05 BMI points (d = 0.76). In addition, eating disorder related cognitions and attitudes of all patients significantly improved with large effect sizes (d = 1.12). On average, all improvements remained stable during the follow-up period.

CONCLUSIONS

Our findings add to the existing studies on day treatment and support previously found encouraging effects of treatment programs that combine day treatment and consecutive outpatient treatment for eating disorders.

Moderators of treatment outcomes in a partial hospitalization and intensive outpatient program for eating disorders

Eating disorders cause a number of severely impairing symptoms that may require more intensive intervention that is available through outpatient therapy services. The PHP/IOP level of care may be an effective mode of treatment in these cases, but few studies have examined overall outcomes or treatment moderators for this level of care. Using a large sample from a PHP/IOP specifically designed for the treatment of eating disorders, the current study examines a variety of symptoms (eating disorder severity, quality of life, depression, etc.) from admission to discharge, as well as potential moderators of treatment, including demographic and clinical factors. Overall, the PHP/IOP level of care was found to improve treatment outcomes. Age, race, gender, and depression were found to moderate the change in quality of life and functional impairment. Additionally, patients diagnosed with anorexia nervosa had significantly lowered quality of life and greater eating disorder symptomatology than all other diagnoses. The results of this study can help to inform clinical practice and help guide in treatment decisions at the partial hospitalization level of care.

Inpatient versus outpatient care, partial hospitalisation and waiting list for people with eating disorders

BACKGROUND

Clinical guidelines recommend outpatient care for the majority of people with an eating disorder. The optimal use of inpatient treatment or combination of inpatient and partial hospital care is disputed and practice varies widely.

OBJECTIVES

To assess the effects of treatment setting (inpatient, partial hospitalisation, or outpatient) on the reduction of symptoms and increase in remission rates in people with:1. Anorexia nervosa and atypical anorexia nervosa;2. Bulimia nervosa and other eating disorders.

SEARCH METHODS

We searched Ovid MEDLINE (1950- ), Embase (1974- ), PsycINFO (1967- ) and the Cochrane Central Register of Controlled Trials (CENTRAL) to 2 July 2018. An earlier search of these databases was conducted via the Cochrane Common Mental Disorders Controlled Trial Register (CCMD-CTR) (all years to 20 November 2015). We also searched the WHO International Clinical Trials Registry Platform and ClinicalTrials.gov (6 July 2018). We ran a forward citation search on the Web of Science to identify additional reports citing any of the included studies, and screened reference lists of included studies and relevant reviews identified during our searches.

SELECTION CRITERIA

We included randomised controlled trials that tested the efficacy of inpatient, outpatient, or partial hospital settings for treatment of eating disorder in adults, adolescents, and children, whose diagnoses were determined according to the DSM-5, or other internationally accepted diagnostic criteria. We excluded trials of treatment setting for medical or psychiatric complications or comorbidities (e.g. hypokalaemia, depression) of an eating disorder.

DATA COLLECTION AND ANALYSIS

We followed standard Cochrane procedures to select studies, extract and analyse data, and interpret and present results. We extracted data according to the DSM-5 criteria. We used the Cochrane tool to assess risk of bias. We used the mean (MD) or standardised mean difference (SMD) for continuous data outcomes, and the risk ratio (RR) for binary outcomes. We included the 95% confidence interval (CI) with each result. We presented the quality of the evidence and estimate of effect for weight or body mass index (BMI) and acceptability (number who completed treatment), in a 'Summary of findings' table for the comparison for which we had sufficient data to conduct a meta-analysis.

MAIN RESULTS

We included five trials in our review. Four trials included a total of 511 participants with anorexia nervosa, and one trial had 55 participants with bulimia nervosa. Three trials are awaiting classification, and may be included in future versions of this review. We assessed a risk of bias from lack of blinding of participants and therapists in all trials, and unclear risk for allocation concealment and randomisation in one study.We had planned four comparisons, and had data for meta-analyses for one. For anorexia nervosa, there may be little or no difference between specialist inpatient care and active outpatient or combined brief hospital and outpatient care in weight gain at 12 months after the start of treatment (standardised mean difference (SMD) -0.22, 95% CI -0.49 to 0.05; 2 trials, 232 participants; low-quality evidence). People may be more likely to complete treatment when randomised to outpatient care settings, but this finding is very uncertain (risk ratio (RR) 0.75, 95% CI 0.64 to 0.88; 3 trials, 319 participants; very low-quality evidence). We downgraded the quality of the evidence for these outcomes because of risks of bias, small numbers of participants and events, and variable level of specialist expertise and intensity of treatment.We had no data, or data from only one trial for the primary outcomes for each of the other three comparisons.No trials measured weight or acceptance of treatment for anorexia nervosa, when comparing inpatient care provided by a specialist eating disorder service and health professionals and a waiting list, no active treatment, or treatment as usual.There was no clear difference in weight gain between settings, and only slightly more acceptance for the partial hospital setting over specialist inpatient care for weight restoration in anorexia nervosa.There was no clear difference in weight gain or acceptability of treatment between specialist inpatient care and partial hospital care for bulimia nervosa, and other binge eating disorders.

AUTHORS' CONCLUSIONS

There was insufficient evidence to conclude whether any treatment setting was superior for treating people with moderately severe (or less) anorexia nervosa, or other eating disorders.More research is needed for all comparisons of inpatient care versus alternate care.

Effect of Hospitalization on Percent Median Body Mass Index at One Year, in Underweight Youth With Restrictive Eating Disorders

PURPOSE

Data from low-weight patients with restrictive eating disorders (EDs) treated in outpatient adolescent medicine-based ED treatment programs were analyzed to determine whether there was an association between hospitalization and gain to at least 90% median body mass index (mBMI) at 1-year follow-up.

METHODS

Data were retrospectively collected for 322 low-weight (<85% mBMI at intake) patients aged 9-21 years, who presented with restrictive EDs to 14 adolescent medicine-based ED programs in 2010. Positive outcome was defined as being at least 90% mBMI (%mBMI = patient's body mass index/mBMI for age × 100) at 1-year follow-up. Association between treatment at a higher level of care and gain to at least 90% mBMI was analyzed for 140 patients who were <85% mBMI at the time of presentation, had not been previously hospitalized, and had 1-year follow-up data available.

RESULTS

For patients presenting at <85% mBMI, those who were hospitalized in the year following intake had 4.0 (95% confidence interval: 1.6-10.1) times the odds of gain to at least 90% mBMI, compared with patients who were not hospitalized, when controlling for baseline %mBMI.

CONCLUSION

In this national cohort of patients with restrictive EDs presenting to adolescent medicine-based ED programs at <85% mBMI, those who were hospitalized had greater odds of being at least 90% mBMI at 1-year follow-up.

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

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

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

OBJECTIVE

The objective of this study was to review the current eating disorders outcome literature after residential or partial hospitalization programme (PHP) treatment.

METHOD

Articles were identified through a systematic search of PubMed and PsycINFO.

RESULTS

Twenty-two PHP and six residential treatment studies reported response at discharge and tended to find improvement. Fewer studies (nine PHP and three residential) reported outcome at some interval after discharge from treatment. These tended to find sustained improvement. A substantial proportion of patients were lost to follow-up, particularly for residential treatment. Only two follow-up studies used controlled trials; both showed efficacy for PHP compared with inpatient treatment with regard to maintaining symptom remission.

CONCLUSIONS

Improvement at discharge may not predict long-term outcome. Long-term follow-up studies were confounded by high dropout rates. While higher levels of care may be essential for reversing malnutrition, there remains a lack of controlled trials showing long-term efficacy, particularly for residential treatment settings.

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.

Systematic review of evidence for different treatment settings in anorexia nervosa

AIM: To compare outcomes in anorexia nervosa (AN) in different treatment settings: inpatient, partial hospitalization and outpatient.

METHODS: Completed and published in the English language, randomized controlled trials comparing treatment in two or more settings or comparing different lengths of inpatient stay, were identified by database searches using terms “anorexia nervosa” and “treatment” dated to July 2014. Trials were assessed for risk of bias and quality according to the Cochrane handbook by two authors (Madden S and Hay P) Data were extracted on trial quality, participant features and setting, main outcomes and attrition.

RESULTS: Five studies were identified, two comparing inpatient treatment to outpatient treatment, one study comparing different lengths of inpatient treatment, one comparing inpatient treatment to day patient treatment and one comparing day patient treatment with outpatient treatment. There was no difference in treatment outcomes between the different treatment settings and different lengths of inpatient treatment. Both outpatient treatment and day patient treatment were significantly cheaper than inpatient treatment. Brief inpatient treatment followed by evidence based outpatient care was also cheaper than prolonged inpatient care for weight normalization also followed by evidence based outpatient care.

CONCLUSION: There is preliminary support for AN treatment in less restrictive settings but more research is needed to identify the optimum treatment setting for anorexia nervosa.

A new service model for the treatment of severe anorexia nervosa in the community: the Anorexia Nervosa Intensive Treatment Team

Aims and method A community intensive treatment service for severe anorexia nervosa is described. The service is multidisciplinary but driven by a focus on psychological formulation. Psychological and dietetic interventions are grounded in a process of active risk management. Evaluations of safety, cost and acceptability of the service are described. Results Patients are highly satisfied with their care. A relatively low mortality rate for such a high-risk population was observed. In-patient bed use and costs were substantially reduced. Clinical implications There is a case for greater use of intensive community care for patients with severe anorexia nervosa, as it can be acceptable to patients, relatively safe and cost less than admission.

The therapeutic process in psychological treatments for eating disorders: a systematic review

OBJECTIVE

For eating disorders, a vast number of investigations have demonstrated the efficacy of psychological treatments. However, evidence supporting the impact of therapeutic process aspects on outcome (i.e., process-outcome research) has not been disentangled.

METHOD

Using the Generic Model of Psychotherapy (GMP) to organize various process aspects, a systematic literature search was conducted on psychological treatment studies for anorexia nervosa, bulimia nervosa, binge-eating disorder, and eating disorders not otherwise specified.

RESULTS

Improved outcomes resulted for family-based treatment compared to individual treatment, for individual compared to group treatment, booster sessions, and positive patient expectations (GMP contract aspect); for nutritional counseling and exercising but not exposure with response prevention as adjunct interventions (therapeutic operations); for highly motivated patients and, to a lesser extent, for therapeutic alliance (therapeutic bond); as well as for rapid response and longer overall treatment duration (temporal patterns). Regarding other GMP aspects, studies on self-relatedness were completely lacking and in-session impacts were rarely investigated.

DISCUSSION

As most studies assessed only a limited number of process aspects, the ability to draw conclusions about their overall impact regarding outcome is rather limited. Therefore, future process-outcome research is needed beyond investigations of treatment efficacy for eating disorders.

Mandating weekly weight gain in a day treatment program for eating disorders

OBJECTIVE

We examined differences in treatment outcome associated with a "self-directed"- versus "external-incentive"-based day treatment protocol for individuals with eating disorders (EDs) with below normal body mass index. The self-directed protocol recommended a weekly 500 g weight gain, but allowed participants freedom to gain weight at their own rate; the "external-incentive" protocol required a minimum weight gain of 500 g/week as a requirement for staying in the program.

METHOD

Weight outcome was available for 49 individuals who were treated with the recommended weight gain protocol, and 40 individuals who were treated with the required weight gain protocol.

RESULTS

Post-treatment weight was significantly higher in patients treated in the required weight gain protocol compared to those treated in the recommended weight gain protocol. All patients, regardless of which program they completed, showed improvements in the measures of eating-disorder and comorbid-psychiatric symptoms.

DISCUSSION

This study demonstrated the benefits of an alteration in protocol that required no additional financial or human resources. Further studies are needed to validate the effectiveness of various day treatment protocol parameters.

A family-based eating disorder day treatment program for youth: examining the clinical and statistical significance of short-term treatment outcomes

This article describes an innovative family-based day treatment program (DTP) for youth with moderate to severe eating disorders. A sample of 65 youth completed a battery of psychological measures pre- and post-treatment and 6 months after program completion. Treatment outcomes were assessed in three main domains: (a) medical stabilization, (b) normalization of eating behavior, and (c) improved psychological functioning. Overall, patients demonstrated statistically significant and clinically meaningful improvements on all outcome measures. Findings indicate that a comprehensive DTP can successfully facilitate positive outcomes in youth with eating disorders and that these improvements can be maintained 6 months post-treatment.

Trajectories of eating and clinical symptoms over the course of a day hospital program for eating disorders

Although it is well-established that day hospital programs for eating disorders significantly reduce clinical symptoms, the pre-test/post-test designs that were previously used do not provide information regarding the trajectory of symptoms during treatment. This study observed, on a weekly basis, the evolution of symptoms of 61 women suffering from eating disorders engaged in a day hospital program, and compared the trajectories of specific subgroups of patients. Results show that (a) the first half of the program was crucial for symptom changes; (b) although completers and non-completers presented similar initial improvement, their trajectories rapidly differentiated; and (c) poorer respondents initially reported more symptoms, showed a slower improvement, and never reached the non-clinical zone, whereas better-respondents reached the non-clinical cut-off point more rapidly.

Psicoterapia como estratégia de tratamento dos transtornos alimentares: análise crítica do conhecimento produzido

O objetivo deste estudo foi empreender uma análise crítica acerca do conhecimento científico produzido sobre a utilização das psicoterapias como estratégia de tratamento dos transtornos alimentares. A partir de buscas nas bases PsycINFO, PePSIC e SciELO, no período entre 1999 e 2011, foram recuperados 35 artigos, categorizados em: psicoterapias breves, grupais, psicodinâmicas, complementares, bem como psicoterapias aliadas a outros tratamentos, como o psicofarmacológico. As abordagens mais frequentemente mencionadas foram psicodinâmicas e cognitivo-comportamentais. A modalidade de atendimento predominante foi a grupal. Ainda que preconizando o uso combinado de diversas estratégias, a literatura é unânime em destacar a importância das psicoterapias no tratamento. A análise crítica evidenciou necessidade de leituras que transcendam a mera identificação de técnicas psicoterápicas consideradas mais eficazes para o tratamento dos transtornos alimentares. Deve-se considerar o contexto mais amplo no qual os tratamentos são propostos, bem como promover um diálogo aberto entre enfoques teóricos, valorizando a pluralidade de saberes e a psicoterapia como prática em permanente transformação.

Clinical outcomes of a novel, family-centered partial hospitalization program for young patients with eating disorders

AIM

Eating disorders (ED) in children and younger adolescents are becoming more evident, but there is a small evidence base for their management in this population. We hypothesized that a new family-centered partial hospital program for young patients would be effective in promoting weight gain, as well as improvement in psychiatric symptoms.

METHODS

A retrospective chart review of 56 patients treated in the program between August 2008 and November 2009 was performed. Historical data, anthropometric variables and scores from psychological instruments [Children's Eating Attitudes Test (ChEAT), Children's Depression Inventory (CDI), and Revised Children's Manifest Anxiety Scale (RCMAS)] were collected on admission and at discharge. After exclusion, 30 patients were available for statistical analysis, using paired t-tests. The primary outcome variables were improvement in weight and change in total ChEAT score. Secondary outcomes included improvements in the CDI and RCMAS scores. Multivariate analysis included linear regression models that controlled for patient-specific fixed effects.

RESULTS

The cohort was 87% female with a mean age of 12.8±2 years; 60% were diagnosed with ED not otherwise specified. Two-thirds had a co-morbid depressive and/or anxiety disorder. Change in weight was significant (p<0.0001), as were improvements on total ChEAT (p<0.0001), CDI (p=0.0002), and RCMAS (p<0.0001) scores. No historical factors were correlated with improvement, nor was use of psychotropic medications. Length of stay in weeks significantly predicted greater weight gain (p=0.004, R2=0.26).

CONCLUSIONS

Patients treated in a family-centered partial hospital program had significant improvements in weight and psychological parameters. This approach holds significant promise for the management of young ED patients.

Evaluation of An Australian Day Treatment Program for Eating Disorders

Day treatment programs (DTP) for eating disorders are being recognised as having therapeutic benefits. However, research is needed to evaluate the effectiveness of DTP to establish their validity. This article reports on the evaluation of a pilot DTP in an Australian mental health setting, which utilised an integrative approach combining evidence-based treatments such as dialectical-behavioural therapy and intensive short-term dynamic psychotherapy offered in a group-based setting. Comparison of pre- and post-treatment data outcome measures for eating disorder pathology and comorbid symptoms was undertaken. Patient satisfaction was also evaluated using qualitative methods. Results indicated a significant reduction in depressive symptoms post-treatment, along with a high degree of satisfaction with the treatment. Limitations of this study, along with the implications of the findings and directions for future research, are discussed.

The effectiveness of a day program for the treatment of adolescent anorexia nervosa

OBJECTIVE

The risks of anorexia nervosa (AN) are well established. Despite its severity, little certainty exists for practitioners, with ethical and financial limitations yielding few controlled studies establishing effective treatments. Thus, other methods of establishing treatment effectiveness are necessary. This study presents preliminary results of an open clinical trial of a day program for adolescents with AN.

METHOD

Participants were 26 anorectic females, 12-18 years, who completed the "Transition Program."

RESULTS

Significant change emerged on measures of weight gain, and behavioral and attitudinal measures of eating pathology. Large effect sizes were evident for weight gain at 6 month follow-up. Preliminary trends suggest that treatment gains on these and other measures of eating pathology were maintained at 6 month follow-up.

DISCUSSION

Preliminary results support day program treatment for adolescents with mild-moderately severe eating disorders. Present outcomes are discussed with respect to the dearth of efficacious treatment options for adolescents.

Naturalistic study of course, effectiveness, and predictors of outcome among female adolescents in residential treatment for eating disorders

Few empirical data address naturalistic outcomes of residential eating disorder (ED) treatment. Study aims were to evaluate course, effectiveness, and predictors of outcome in a residential treatment program. We evaluated 80 consecutively admitted female adolescents with the SCID-IV. Primary outcomes were treatment completion, subsequent readmission, clinical global impressions, and changes in body weight. Mean length of stay was 51 days, and 80% of patients were discharged according to treatment plans. Mean expected body weight (EBW) for AN patients increased from 80% to 91%. Patients reported significant improvements in ED symptoms, depression, and quality of life. Low admission %EBW and previous psychiatric hospitalizations were associated with premature termination. Overall, findings support that residential treatment is largely acceptable to patients, and that residential care may provide an opportunity for substantive therapeutic gains.

An evaluation of the effectiveness and short-term stability of an innovative Australian day patient programme for eating disorders

There is a dearth of literature evaluating day patient treatment for eating disorders based upon the targeted goals of treatment, to conclude that day patient programmes are effective. This study aimed to explore the effectiveness of an innovative day patient programme by examining whether the seven key treatment goals improved across treatment and were maintained 3 months after discharge. Of the 58 participants who completed measures assessing BMI, eating disorder cognitions, behaviours, core beliefs, readiness to change, quality of life and perpetuating factors at admission, discharge and follow-up, 44 completed the day programme with 14 non-completers. The results demonstrated that all seven treatment goals improved across treatment and the improvements were maintained or further improved at 3 month follow-up. The results are discussed in context of the published day patient programme literature with implications for future research to maximise optimal treatment outcomes from day patient treatment.

Psychological treatments for bulimia nervosa and binging

BACKGROUND

A specific manual-based form of cognitive behavioural therapy (CBT) has been developed for the treatment of bulimia nervosa (CBT-BN) and other common related syndromes such as binge eating disorder. Other psychotherapies and modifications of CBT are also used.

OBJECTIVES

To evaluate the efficacy of CBT, CBT-BN and other psychotherapies in the treatment of adults with bulimia nervosa or related syndromes of recurrent binge eating.

SEARCH STRATEGY

Handsearch of The International Journal of Eating Disorders since first issue; database searches of MEDLINE, EXTRAMED, EMBASE, PsycInfo, CURRENT CONTENTS, LILACS, SCISEARCH, CENTRAL and the The Cochrane Collaboration Depression, Anxiety & Neurosis Controlled Trials Register; citation list searching and personal approaches to authors were used. Search date June 2007.

SELECTION CRITERIA

Randomised controlled trials of psychotherapy for adults with bulimia nervosa, binge eating disorder and/or eating disorder not otherwise specified (EDNOS) of a bulimic type which applied a standardised outcome methodology and had less than 50% drop-out rate.

DATA COLLECTION AND ANALYSIS

Data were analysed using the Review Manager software program. Relative risks were calculated for binary outcome data. Standardised mean differences were calculated for continuous variable outcome data. A random effects model was applied.

MAIN RESULTS

48 studies (n = 3054 participants) were included. The review supported the efficacy of CBT and particularly CBT-BN in the treatment of people with bulimia nervosa and also (but less strongly due to the small number of trials) related eating disorder syndromes.Other psychotherapies were also efficacious, particularly interpersonal psychotherapy in the longer-term. Self-help approaches that used highly structured CBT treatment manuals were promising. Exposure and Response Prevention did not enhance the efficacy of CBT.Psychotherapy alone is unlikely to reduce or change body weight in people with bulimia nervosa or similar eating disorders.

AUTHORS' CONCLUSIONS

There is a small body of evidence for the efficacy of CBT in bulimia nervosa and similar syndromes, but the quality of trials is very variable and sample sizes are often small. More and larger trials are needed, particularly for binge eating disorder and other EDNOS syndromes. There is a need to develop more efficacious therapies for those with both a weight and an eating disorder.

Self-esteem in patients treated for anorexia nervosa

Anorexia nervosa (AN) mainly affects girls or women between 13 and 45 years of age. According to previous studies, one of the reasons for the desire to be thin is low self-esteem. The purpose of the study was to examine the self-esteem of 38 female patients with AN between 16 and 25 years of age, before and after 3 months of treatment at a specialist ward for eating disorders in Göteborg, Sweden. A quantitative pre- and post-assessment based on two self-rating questionnaires, the Rosenberg Self-Esteem Scale (RSE-S) and three subscales (weight phobia, body dissatisfaction, and ineffectiveness) of Eating Disorder Inventory-2 (EDI-2), together with body mass index (BMI), were used in the study, which was conducted between June 2005 and March 2008. The results reveal that self-esteem, BMI, weight phobia, and body dissatisfaction improved significantly between pre- and post-treatment. The RSE-S and EDI-2 ineffectiveness correlate highly with one another, which lends support to convergent validity, and the internal consistency was high for both the RSE-S and EDI-2 ineffectiveness. The results indicate that the treatment was effective, as both patients' self-esteem and BMI increased after completed treatment, which was the primary goal of the treatment at this ward. Future studies should focus on follow up and the way self-esteem manifests itself at different points in time within an individual.

Day hospital programmes for eating disorders: a review of the similarities, differences and goals

Day hospital (DH) treatments for eating disorders (EDs) provide intensive daily care and allow patients to maintain and test their social relations and coping skills at home and outside. Although widespread, their description is lacking. This review compares the different types of DH described in the literature and presents our DH experience in Turin, Italy. We searched Psychinfo and Pubmed with the following keywords: anorexia nervosa, bulimia nervosa, EDs, DH, day treatment and partial hospitalisation. We found and reviewed the DH programmes of eleven specialised centres, which have some shared features but also many differences, suggesting that DH treatments are still largely experimental. Briefly, the shared elements are: biopsychosocial model as reference frame; cognitive-behavioural model or techniques; behavioural contract; patients' selection; body image therapy; involvement of family; weight normalisation/weight gain and modification/normalisation of eating behaviour as objectives. Nonetheless, shared opinions concerning inclusion criteria are lacking; the duration of DH treatment is surprisingly different among centres (from 3 to 39 weeks); the approach to eating and compensation behaviours ranges from control to autonomy; followup and psychometric assessment can be either performed or not; psychological and behavioural objectives can be different. This review suggests the existence of two different DH models: the first has a shorter duration and is mainly symptom-focused; the second is more individual-focused, has a longer duration and is focused on patients' relational skills, psychodynamic understanding of symptoms and more gradual changes in body weight. Further investigation is required to make DH treatment programmes measurable and comparable.

A Dutch day treatment program for anorexia and bulimia nervosa in comparison with internationally described programs

A Dutch day treatment program for patients with anorexia and bulimia nervosa is described and compared to intensive day treatment programs for patients with eating disorders outlined in international literature. The 5-day program is described in terms of its general characteristics, intended outcome and specific treatment interventions. Along these parameters it is compared to the programs found in a systematic literature search of day hospitalization programs for eating disorders. Global inspection shows a lot of similarities between all the programs. Looking more closely, also many important differences exist (concerning, e.g. treatment duration, intensity of treatment, theoretical orientation, goals of treatment and weight gain regime). Because of the differences, it is hard to compare outcome data between centres. Besides, on many of these dimensions, the literature does not yet tell us unambiguously what is best for our patients. Therefore, it is necessary to keep the dialogue between treatment centres going.

From general day hospital treatment to specialized treatment programmes

Approximately one third of day hospitals in Europe can be designated as predominantly psychotherapeutic. They address mainly patients with personality disorders (PD), but also eating disorders and chronic mood and anxiety disorders without PD. As day treatment programmes tend to become associated with mental health centers, their treatment intensity also tends to become reduced. Available data suggest that approximately 10 hours of treatment a week is sufficient. Is such treatment more effective than specialized outpatient treatment? This research question will probably set the agenda in the years to come. In response to this challenge, day treatment should become more specialized. Data from the Norwegian Network of Psychotherapeutic Day Hospitals (n = 2.205) demonstrate that the majority of day treatment patients suffer from borderline and avoidant PD. Programmes for patients with borderline PD are well developed. The authors call for programme development for patients with avoidant PD.

Individual psychotherapy in the outpatient treatment of adults with anorexia nervosa

BACKGROUND

Anorexia nervosa is a disorder of high morbidity and significant mortality. It is commonest 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 psychotherapies are presently used in treatment.

OBJECTIVES

The aim of the present review was to evaluate the evidence from randomised controlled trials for the efficacy of outpatient psychotherapies used in the treatment of older adolescents and adults with anorexia nervosa

SEARCH STRATEGY

The strategy comprised database searches of MEDLINE, EXTRAMED, EMBASE,PSYCLIT, CURRENT CONTENTS, Cochrane Collaboration Controlled Trials Register and the Depression and Anxiety Neuroses Cochrane Group (CCDAN), a hand-search of The International Journal of Eating Disorders, and he reference lists of all papers selected. Personal letters were sent to identified notable researchers published in the area, requesting information on trials that are unpublished or in progress.

SELECTION CRITERIA

All randomised controlled trials of adult individual outpatient therapy for anorexia nervosa as defined by the DSM-IV or similar international criterion. Quality ratings were made according to the CCDAN criteria and in addition, whether the trial had examined treatment integrity.

DATA COLLECTION AND ANALYSIS

A range of outcome variables were selected, including physical state, severity of eating disorder attitudes and beliefs, interpersonal function, and general psychiatric symptom severity. Continuous outcome data comparisons were made with the standardized mean difference statistic, and binary outcome comparisons made with the relative risk statistic. Reliability of data extraction and quality ratings were made with the kappa statistic. Sensitivity analyses to evaluate the effects of trial quality and subgroup analyses to explore specific questions of treatment effects from different settings, frequency and duration of therapies were planned.

MAIN RESULTS

Six small trials only, two of which included children or adolescents, were identified from the search and aggregation of data was not possible. Bias was possible due particularly to lack of blinding of outcome assessments. The results in two trials suggested that 'treatment as usual' or similar may be less efficacious than a specific psychotherapy. 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.

REVIEWER'S CONCLUSIONS

No specific approach can be recommended from this review. It is unclear why 'treatment as usual' performed so poorly or why dietary advice alone appeared so unacceptable as the reasons for non-completion were not reported. There is an urgent need for large well-designed trials in his area.
