In search of predictors of dropout from inpatient treatment for anorexia nervosa

Premature termination of inpatient eating disorder treatment: Does timing matter?

BACKGROUND

Premature termination of treatment is a serious problem in the treatment of eating disorders. Prior research attempting to differentiate patients who are able to complete treatment from those who terminate early has yielded mixed results. One proposed explanation for this is a failure to examine the time course of treatment termination. This study was designed to explore associations between baseline patient characteristics and timing of treatment termination.

METHODS

Participants were 124 eating disorder patients admitted voluntarily to the inpatient program at Toronto General Hospital between 2009 and 2015. At admission, all patients completed measures of eating disorder symptoms, eating disorder cognitions, depressive symptoms and emotional dysregulation. Body weight was measured weekly. Data analyses were completed using one-way ANOVAs and Chi Square tests.

RESULTS

Results showed significant associations between timing of treatment termination and eating disorder diagnosis, severity of eating disorder cognitions and severity of depressive symptoms. Post-hoc analyses revealed that patients who left treatment early had more severe depressive symptoms, eating disorder cognitions related to eating and difficulties engaging in goal directed behaviors when emotionally dysregulated.

CONCLUSIONS

Patients who terminated inpatient treatment early in their admissions differ from patients who terminated later and those who completed treatment. These differences have potential clinical implications for the clinical management of patients with severe eating disorders requiring inpatient admission.

The impact of personality disorders and personality traits on psychotherapy treatment outcome of eating disorders: A systematic review

A significant proportion of those with eating disorders (EDs) do not respond to first-line treatments. This systematic review was conducted to identify whether personality disorders (PDs)/traits predict or moderate ED treatment outcomes and whether these outcomes were differentially influenced by ED or PD diagnostic subtypes, or treatment approach. A comprehensive systematic literature search was conducted using the PRISMA guidelines. A total of seven randomised controlled trials (RCTs) plus four follow-up studies were reviewed investigating the impact of PD and PD traits on treatment outcomes for EDs. The majority indicated that PD had some impact on treatment outcomes. Outcome measures and time-point measurements varied across studies. Included studies suggested that bulimia nervosa treatment outcomes were not hindered by co-morbidity of borderline PD; however, psychiatric impairment remained high at post-treatment and follow-up. Cluster C PDs were found to negatively impact treatment outcomes for binge ED and attrition rates for anorexia nervosa. Included studies suggested that interventions that addressed aspects of personality pathology showed greater main effects for ED treatment outcomes. There is an urgent need for future RCTs on ED treatments to include routine measures of core personality features to allow their impacts to be more thoroughly examined and for psychotherapies to be tailored accordingly.

[Diversity of hospital care for anorexia nervosa in psychiatry in France]

BACKGROUND

Hospitalization is rare in anorexia nervosa (AN) and local application of indications is heterogeneous. However, no study has evaluated the effect of these different treatment modalities on the mean length of stay. Our objective was to describe the context and modalities of a wide range of hospital care programs offered to patients with anorexia nervosa in eleven specialized French psychiatric centers for patients from childhood to adulthood. This work was carried out within the framework of the EVHAN (Evaluation of Hospitalization for AN, Eudract number: 2007-A01110-53, registered in Clinical trials) research program. The EVHAN program comprises five main lines: weight objectives at discharge, the practice or not of a separation period, the use of clear nutritional dietary objectives (cognitive/behavioral), the intensity of family involvement in treatment, and the existence or absence of a stabilization phase before ending inpatient treatment. These main lines will make it possible to study the impact of treatment modalities on the future of patients in the short and medium term (at discharge and at 1-year follow-up).

METHODS

The eleven centers are located in France (Bordeaux, Nantes, Paris and Ile-de-France, Rouen and Saint-Étienne). Various staff members (psychiatrists, somatic doctors, nurses, dieticians, psychologists) from each center were interviewed using a semi-structured questionnaire. Data on operating modalities and context of care were collected and analyzed.

RESULTS

Four of the eleven centers were exclusively child/adolescent centers, and seven of 11 were adolescent (from 11, 13 or 16 years) and young adult centers. All centers offered a graduated approach from outpatient to full hospitalization. The majority had a number of beds allocated for patients with eating disorders. The criteria for hospitalization were homogeneous with respect to somatic and/or psychic severity prefiguring the consensus criteria defined by the French Health Authority (HAS) in 2010. Child/adolescent units used the weight curve to set weight objectives at discharge (between the 10th and 50th percentiles). Most adult units used weight objectives at discharge corresponding to a body mass index between 17 and 20kg/m². Nine centers used a written or oral care contract. One unit did not separate the patient from her/his usual environment, the others had a practice gradient of partial separation and total separation times. These were either short, lasting a maximum of 3 weeks, or long, lasting more than 3 weeks. Conversely, patients were not isolated within the unit, and benefited from a rich social life, depending on her/his physical condition. The patient's family was in contact with the team and fully supported. The longest periods of separation involved adolescents and adults. Nutritional support varied from a group approach (meals in the dining room, standardized meals of the care center) to very individualized approaches within a specific framework. All the units reported meeting with families at least once during the hospitalization; with the patient's parents for child/adolescent patients and/or unmarried patients and with the husband/wife for married patients. The majority of the centers requested a phase of weight stabilization, whatever the age before hospital discharge.

CONCLUSION

There is international and national consensus regarding the indications for hospitalization, and the main lines of multidisciplinary care to be developed within this framework. However, local application of these indications was heterogeneous resulting in diverse modalities of hospital care for anorexia nervosa in France. Specialized teams have developed management strategies arising from their "team culture". The complexity of the anorexic pathology, due to the psyche-soma intrication and the diversity of age groups, highlights the complexity of care available. The impact of this diversity of hospital care on patient outcomes will be studied as a result of this work.

Length of stay for anorexia nervosa: Systematic review and meta-analysis

OBJECTIVE

Evidence regarding global trends in length of stay for patients with anorexia nervosa is limited. The aim of this study is to conduct a meta-analysis examining the length of stay for anorexia nervosa patients globally, and to investigate moderators of the variance.

METHOD

Medline, EMBASE and PsycINFO were searched for studies published up to January 2019. Two independent reviewers assessed the eligibility of each report based on predefined inclusion criteria. A meta-analysis was performed to calculate a pooled mean length of stay using the random-effects model. Subgroup analyses and meta-regression were conducted to explore potential sources of heterogeneity between studies.

RESULTS

Of 305 abstracts reviewed, 71 studies met the inclusion criteria, generating 111 datasets. The pooled mean length of stay (95% confidence interval) was 76.3 days (73.3, 79.4) using the random-effects model, with marked variation across countries and time. Heterogeneity between studies was explained by age and admission body mass index.

CONCLUSIONS

This meta-analysis found that although clinical features do contribute to length of admissions for anorexia nervosa, there are also global and temporal variations. Future research should provide an in-depth analysis of why and how this variation exists and what the impact is on the well-being of people with anorexia nervosa.

Predictors of illness course and health maintenance following inpatient treatment among patients with anorexia nervosa

BACKGROUND

Anorexia nervosa (AN) is a life-threatening psychiatric disorder associated with significant medical and psychosocial impairment. Hospital-based behavioral treatment is an effective intervention in the short-term. However, relapse rates following discharge are high and thus, there is a need to identify predictors of longitudinal outcome. The current study provides information regarding illness course and health maintenance among patients with AN over 5 years following discharge from an eating disorder inpatient unit.

METHODS

Participants were individuals with AN who were discharged from a specialized, inpatient behaviorally-based unit. Prior to discharge, height and weight were measured and participants completed self-report measures of eating disorder severity and general psychopathology (depression, anxiety, harm avoidance). Participants were contacted annually for self-report measures of weight, eating disorder severity and clinical impairment. Outcome was defined by illness course (body mass index (BMI) and clinical impairment during the 5 years) and health maintenance (categories of weight and eating disorder symptom severity) across follow-up, using all available data. Linear mixed models were used to examine whether demographic and clinical parameters at discharge predicted BMI and clinical impairment over time. Additional analyses examined whether these variables significantly influenced an individual's likelihood of maintaining inpatient treatment gains.

RESULTS

One-hundred and sixty-eight individuals contributed data. Higher trait anxiety at discharge was associated with a lower BMI during follow-up (p = 0.012). There was a significant interaction between duration of illness and time, whereby duration of illness was associated with a faster rate of weight loss (p = 0.003) during follow-up. As duration of illness increased, there was a greater increase in self-reported clinical impairment (p = 0.011). Increased eating disorder severity at discharge was also associated with greater clinical impairment at follow-up (p = 0.004). Higher BMI at discharge was significantly associated with maintaining healthy weight across a priori BMI-based definitions of health maintenance.

CONCLUSIONS

Weight status (higher BMI) and duration of illness are key factors in the prognosis of AN. Higher weight targets in intensive treatments may be of value in improving outcomes.

Factors associated with weight gain in anorexia nervosa inpatients

OBJECTIVE

Nutrition restoration in inpatients with anorexia nervosa (AN) is a core element in treatment, enabling recovery of cognitive functions essential for psychological care. This study aims to identify factors associated with inpatient weight gain.

METHODS

Medical records from 107 inpatients aged 13-55 years with AN, hospitalized for more than 7 days at a specialized unit, were examined in a retrospective study. Weight evolution graphs were created for each patient and graded independently as optimal, moderate, and inadequate weight gain after 2 weeks and increasing, flat or decreasing weight in the first 2 weeks by expert clinicians. Driven by explicit hypotheses, bivariable analyses were carried out to detect relevant factors associated with weight gain during and after the first 2 weeks of admission.

RESULTS

Initial weight gain in the first 2 weeks of hospitalization and the introduction of a protocol harmonizing treatment procedures around rapid refeeding were strong factors associated with optimal weight gain after 2 weeks of hospitalization, whereas prior hospitalization in a psychiatric unit, diagnosis with binge-eating/purging subtype and age over 18 years were significantly associated with inadequate weight gain (p < 0.001-0.05).

CONCLUSION

To promote weight gain during hospitalization, clinicians should consider the following therapeutic measures: rapid refeeding strategies, renutrition protocols, and controlling purging behaviors.

User satisfaction with family-based inpatient treatment for adolescent anorexia nervosa: retrospective views of patients and parents

BACKGROUND

Research is scarce on patient and parent satisfaction with family-based treatment for adolescent anorexia nervosa (AN), especially family-based treatment adapted to inpatient settings. The purpose of this study was to describe and compare patient and parent satisfaction with an inpatient family-based treatment program for adolescent AN, and to investigate whether the level of satisfaction with treatment was associated with eating disorder outcome.

METHODS

Former patients and their parents were contacted approximately five years (4.5 ± 1.7, range: 1.3-7.0) after discharge from family-based inpatient treatment. Ninety-four participants (patients: n = 34, mothers: n = 40, fathers: n = 20) from 46/58 (79.3%) families took part in the study. Former patients and both parents completed treatment satisfaction questionnaires. Outcome at follow-up was assessed by the Eating Disorder Examination Questionnaire and body mass index (kg/m²).

RESULTS

Overall, mothers and fathers reported a high level of satisfaction with treatment, while the former patients' satisfaction was moderate. There were no significant differences between treatment satisfaction scores for mothers and fathers. However, the former patients' treatment satisfaction scores were significantly lower than the parents' scores on several of the items. Correlations between eating disorder outcome parameters and treatment satisfaction were small, except for fathers' satisfaction with treatment and weight outcome at follow-up.

DISCUSSION

Family-based treatment adapted to inpatient settings is a novel treatment approach for adolescents with AN that require hospitalization. Inclusion and empowerment of parents are considered crucial in outpatient family-based treatment, but may be just as important in inpatient programs. Mothers and fathers alike reported high levels of satisfaction with treatment, which may constitute an important factor in the success of family-based treatment.

CONCLUSION

Family-based inpatient treatment for adolescents with severe AN who have failed to respond to outpatient treatment seemed to be highly valued by parents and viewed by adolescents as acceptable. Parental satisfaction with their child's treatment is likely to be an important factor for treatment implementation and adherence both in outpatient and inpatient settings.

Pre-treatment patient characteristics as predictors of drop-out and treatment outcome in individual and family therapy for adolescents and adults with anorexia nervosa: A systematic review and meta-analysis

Understanding variables predicting drop-out or unfavourable outcome following treatment for anorexia nervosa (AN) may help to improve upon intervention efforts. However, the current literature has demonstrated sparse and inconsistent significant findings. The current systematic review and meta-analysis summarised the evidence base examining baseline predictors of drop-out and outcome in AN treatment. A literature search was conducted to identify research investigating predictors of drop-out and outcome in individuals treated for AN. Four online databases were searched, and predictors were organised by category and dependent variable (outcome versus drop-out). 27 studies were included. Lower motivation, lower BMI, and having the binge-purge subtype of AN predicted drop-out. Greater ED pathology and poorer motivation predicted poorer outcome. Clinical recommendations include taking particular care during assessment stages to identify patients at risk of drop-out and/or poor outcome based on their clinical profile and level of motivation for recovery. At-risk patients should be receiving tailored treatment to enhance engagement and reduce risk of drop-out. In conclusion, there's some evidence that motivation, BMI, subtype, and ED pathology predicts drop-out and/or outcome in individual and family-based therapy for AN amongst adolescents and adults; however, research incorporating carefully designed multi-site studies is required to further examine these findings.

Treatment dropout in web-based cognitive behavioral therapy for patients with eating disorders

Treatment dropout is an important concern in eating disorder treatments as it has negative implications for patients' outcome, clinicians' motivation, and research studies. Our main objective was to conduct an exploratory study on treatment dropout in a two-part web-based cognitive behavioral therapy with asynchronous therapeutic support. The analysis included 205 female patients with eating disorders. Reasons for dropout, treatment experiences, and predictors of dropout were analyzed. Overall treatment dropout was 37.6%, with 18.5% early dropout (before or during treatment part 1) and 19.0% late dropout (after part 1 or during part 2). Almost half of the participants identified personal circumstances as reason for dropout. The other participants mostly reported reasons related to the online delivery or treatment protocol. Predictors of early dropout included reporting less vigor and smoking at baseline and a longer average duration per completed treatment module of part 1. Late dropout was predicted by reporting less vigor at baseline and uncertainty about recommendation of the treatment to others after completion of treatment part 1. Generally, the web-based treatment and online therapeutic support were evaluated positively, although dropouts rated the treatment as significantly less helpful and effective than completers did.

Predictive factors of dropout from inpatient treatment for anorexia nervosa

BACKGROUND

Patients with severe Anorexia Nervosa (AN) whose condition is life-threatening or who are not receiving adequate ambulatory care are hospitalized. However, 40 % of these patients leave the hospital prematurely, without reaching the target weight set in the treatment plan, and this can compromise outcome. This study set out to explore factors predictive of dropout from hospital treatment among patients with AN, in the hope of identifying relevant therapeutic targets.

METHODS

From 2009 to 2011, 180 women hospitalized for AN (DSM-IV diagnosis) in 10 centres across France were divided into two groups: those under 18 years (when the decision to discharge belongs to the parents) and those aged 18 years and over (when the patient can legally decide to leave the hospital). Both groups underwent clinical assessment using the Morgan & Russell Global Outcome State questionnaire and the Eating Disorders Examination Questionnaire (EDE-Q) for assessment of eating disorder symptoms and outcome. Psychological aspects were assessed via the evaluation of anxiety and depression using the Hospital Anxiety and Depression Scale (HADS). Socio-demographic data were also collected. A number of factors identified in previous research as predictive of dropout from hospital treatment were tested using stepwise descending Cox regressions.

RESULTS

We found that factors predictive of dropout varied according to age groups (being under 18 as opposed to 18 and over). For participants under 18, predictive factors were living in a single-parent family, severe intake restriction as measured on the "dietary restriction" subscale of the Morgan & Russell scale, and a low patient-reported score on the EDE-Q "restraint concerns" subscale. For those over 18, dropout was predicted from a low depression score on the HADS, low level of concern about weight on the EDE-Q subscale, and lower educational status.

CONCLUSION

To prevent dropout from hospitalization for AN, the appropriate therapeutic measures vary according to whether patients are under or over 18 years of age. Besides the therapeutic adjustments required in view of the factors identified, the high dropout rate raises the issue of resorting more frequently to compulsory care measures among adults.

Personality differences in treatment-seeking and non-treatment-seeking individuals with self-reported anorexia

Research on anorexia has tended to focus on individuals who are seeking treatment, leading to treatment models that are based on individuals already receiving help. Therefore, the purpose of this study was to explore personality differences between individuals seeking treatment and those not seeking treatment for anorexia. Participants were 148 women recruited from three online sources. They completed a personality measure derived from the five-factor model and the Eating Attitudes Test-26. Results indicated that individuals with anorexia who were not seeking treatment scored lower on Agreeableness and Conscientiousness than both individuals seeking treatment and a control group. Also, individuals with anorexia in general tended to score lower on Extraversion and higher on Neuroticism than individuals in a control group. These results suggest that being open about treatment options, increasing successes, motivation, and organization, and highlighting the seriousness of anorexia could be beneficial in getting individuals with anorexia to seek and continue in treatment.

Predictors of treatment outcome in individuals with eating disorders: A systematic review and meta-analysis

OBJECTIVE

Understanding the factors that predict a favourable outcome following specialist treatment for an eating disorder may assist in improving treatment efficacy, and in developing novel interventions. This review and meta-analysis examined predictors of treatment outcome and drop-out.

METHOD

A literature search was conducted to identify research investigating predictors of outcome in individuals treated for an eating disorder. We organized predictors first by statistical type (simple, meditational, and moderational), and then by category. Average weighted mean effect sizes (r) were calculated for each category of predictor.

RESULTS

The most robust predictor of outcome at both end of treatment (EoT) and follow-up was the meditational mechanism of greater symptom change early during treatment. Simple baseline predictors associated with better outcomes at both EoT and follow-up included higher BMI, fewer binge/purge behaviors, greater motivation to recover, lower depression, lower shape/weight concern, fewer comorbidities, better interpersonal functioning and fewer familial problems. Drop-out was predicted by more binge/purge behaviors and lower motivation to recover. For most predictors, there was large interstudy variability in effect sizes, and outcomes were operationalized in different ways. There were generally insufficient studies to allow analysis of predictors by eating disorder subtype or treatment type.

DISCUSSION

To ensure that this area continues to develop with robust and clinically relevant findings, future studies should adopt a consistent definition of outcome and continue to examine complex multivariate predictor models. Growth in this area will allow for stronger conclusions to be drawn about the prediction of outcome for specific diagnoses and treatment types.

Could training executive function improve treatment outcomes for eating disorders?

Current gold standard treatments for eating disorders (EDs) lack satisfactory efficacy, and traditional psychological treatments do not directly address executive functioning deficits underpinning ED pathology. The goal of this paper is to explore the potential for enhancing ED treatment outcomes by improving executive functioning deficits that have been demonstrated to underlie eating pathology. To achieve our objective, we (1) review existing evidence for executive functioning deficits that underpin EDs and consider the extent to which these deficits could be targeted in neurocognitive training programs, (2) present the evidence for the one ED neurocognitive training program well-studied to date (Cognitive Remediation Therapy), (3) discuss the utility of neurocognitive training programs that have been developed for other psychiatric disorders with similar deficits, and (4) provide suggestions for the future development and research of neurocognitive training programs for EDs. Despite the fact that the body of empirical work on neurocognitive training programs for eating disorders is very small, we conclude that their potential is high given the combined evidence for the role of deficits in executive functioning in EDs, the initial promise of Cognitive Remediation Training, and the success in treating related conditions with neurocognitive training. Based on the evidence to date, it appears that the development and empirical evaluation of neurocognitive training programs for EDs is warranted.

Review of smartphone applications for the treatment of eating disorders

mHealth tools may be a feasible modality for delivering evidence-based treatments and principles (EBPs), and may enhance treatment for eating disorders (EDs). However, research on the efficacy of mHealth tools for EDs and the extent to which they include EBPs is lacking. The current study sought to (i) review existing apps for EDs, (ii) determine the extent to which available treatment apps utilize EBPs, and (iii) assess the degree to which existing smartphone apps utilize recent advances in smartphone technology. Overall, existing ED intervention apps contained minimal EBPs and failed to incorporate smartphone capabilities. For smartphone apps to be a feasible and effective ED treatment modality, it may be useful for creators to begin taking utilizing the abilities that set smartphones apart from in-person treatment while incorporating EBPs. Before mHealth tools are incorporated into treatments for EDs, it is necessary that the feasibility, acceptability, and efficacy be evaluated.

Between difference and belonging: configuring self and others in inpatient treatment for eating disorders

Dedicated inpatient care for eating disorders has profound impact on patients' embodied practices and lived realities. Analyses of inpatients' accounts have shown that participants endorse complex and conflicting attitudes toward their experiences in eating disorders wards, yet the apparent ambivalence that characterizes inpatient experiences has not been subject to critical examination. This paper examines the narrated experiences of 13 participants (12 women and one man; age 18–38 years at first interview) with past or present anorexia nervosa, bulimia nervosa, or eating disorder not otherwise specified, who had been hospitalized in an inpatient eating disorders ward for adults in central Israel. The interviews, which took place in 2005–2006, and again in 2011, were part of a larger longitudinal study exploring the subjective experiences of eating disorders and recovery among Israeli adults. Employing qualitative analysis, this study finds that the participants' accounts were concerned with dynamics of difference and belonging, as they played out in various aspects of inpatient care, including diagnosis, treatment, relationships with fellow patients and staff, and everyday life in hospital. Notably, participants simultaneously defined themselves as connected to, but also distinct from, the eating disordered others who formed their reference group at the ward. Through negotiating a protectively ambivalent positioning, participants recognized their eating disordered identities and connected with others on the ward, while also asserting their non-disordered individuality and distancing themselves from the potential dangers posed by ‘excessive’ belonging. The paper suggests that this ambivalent positioning can usefully be understood through the anthropological concept of liminality: being both a part of and apart from one's community.

Clinical characteristics associated with premature termination from outpatient psychotherapy for anorexia nervosa

AIM

The literature on clinical characteristics associated with premature termination of treatment (PTT) is beset with conflicting and non-replicated findings. This study explores clinical characteristics potentially associated with PTT in a randomised controlled outpatient psychotherapy trial for anorexia nervosa (AN).

METHODS

Participants were 56 women aged 17-40 years with spectrum AN. The completer group (n = 35) included those completing at least 15/20 planned sessions with the remainder of the sample comprising the PTT group (n = 21). Variables examined included demographic factors, psychosocial functioning, psychiatric history, lifetime comorbidity, temperament and eating disorder characteristics. Logistic regression was used to examine significant variables. A Kaplan-Meier survival curve was used to illustrate time taken to PTT.

RESULTS

The mean number of sessions in the PTT group was 8.1. Lower self-transcendence scores on the Temperament and Character Inventory were associated with PTT.

CONCLUSIONS

Recognising and addressing personality factors have the potential to enhance retention in treatment.

Internet-based motivation program for women with eating disorders: eating disorder pathology and depressive mood predict dropout

BACKGROUND

One of the main problems of Internet-delivered interventions for a range of disorders is the high dropout rate, yet little is known about the factors associated with this. We recently developed and tested a Web-based 6-session program to enhance motivation to change for women with anorexia nervosa, bulimia nervosa, or related subthreshold eating pathology.

OBJECTIVE

The aim of the present study was to identify predictors of dropout from this Web program.

METHODS

A total of 179 women took part in the study. We used survival analyses (Cox regression) to investigate the predictive effect of eating disorder pathology (assessed by the Eating Disorders Examination-Questionnaire; EDE-Q), depressive mood (Hopkins Symptom Checklist), motivation to change (University of Rhode Island Change Assessment Scale; URICA), and participants' age at dropout. To identify predictors, we used the least absolute shrinkage and selection operator (LASSO) method.

RESULTS

The dropout rate was 50.8% (91/179) and was equally distributed across the 6 treatment sessions. The LASSO analysis revealed that higher scores on the Shape Concerns subscale of the EDE-Q, a higher frequency of binge eating episodes and vomiting, as well as higher depression scores significantly increased the probability of dropout. However, we did not find any effect of the URICA or age on dropout.

CONCLUSIONS

Women with more severe eating disorder pathology and depressive mood had a higher likelihood of dropping out from a Web-based motivational enhancement program. Interventions such as ours need to address the specific needs of women with more severe eating disorder pathology and depressive mood and offer them additional support to prevent them from prematurely discontinuing treatment.

Premature termination of treatment for anorexia nervosa: differences between patient-initiated and staff-initiated discharge

OBJECTIVES

To investigate treatment drop-out by comparing clinical indicators of patients whose discharge was initiated by staff with those who initiated discharge themselves.

METHOD

Ninety participants with anorexia completed questionnaires at admission and four weeks into hospitalized treatment. Weight data was collected over this same period. At discharge, participants were categorized into completer (n = 38) or patient-initiated (n = 36) /staff-initiated (n = 16) premature termination groups.

RESULTS

Significant differences between staff-initiated and patient-initiated discharge groups were found at admission. Staff initiated groups were on average older (p = .035), and more likely to have had prior compelled treatment (p = .039). At 4 weeks those in the patient-initiated group had put on weight at a faster rate (p = .032) and reported a decrease in alliance (p = .017). At discharge, staff initiated discharge demonstrated greater time in treatment (p = .001), greater weight gain (p = .027), and a higher discharge BMI (p = .013). At discharge, staff-initiated drop-outs had comparable end-of-treatment outcomes to those who completed treatment as planned.

DISCUSSION

There are key differences between those who prematurely discharge themselves from treatment, compared to those who are prematurely discharged by clinical staff. Future research into drop-out needs to take into account and recognize these differences.

Drop-out from adolescent and young adult inpatient treatment for anorexia nervosa

We examined factors predictive of dropout from inpatient treatment for anorexia nervosa (AN) among adolescents in a prospective study of 359 consecutive hospitalizations for AN (DSM-IV). Patients were assessed at admission (clinical, socio-demographic, and psychological data). Multivariate analyses were performed. Drop-out (i.e. leaving hospital before the target weight is achieved) occurred in 24% (n=86) of hospitalizations; in 42.3% (n=30) of the cases, dropout was initiated by the treatment team and in 58.6% (n=41) by the patients and/or their parents. 18.6% (16/86) occurred during the first half of the inpatient program. Frequency of drop-out was significantly higher when the patient was living with only one parent, had been hospitalized previously, had a lower BMI at admission and was over 18 at admission. These elements should draw the attention of the clinician, so that he/she can prepare hospitalization with patients presenting lower admission BMI, particularly by motivational interventions for a better therapeutic alliance, and by the deployment of intensive accompaniment of single parents. Further studies aiming to replicate these results, and including the evaluation of other clinical dimensions such as impulsivity and other personality traits, are needed to elucidate this important topic.

Predicting premature termination of hospitalised treatment for anorexia nervosa: the roles of therapeutic alliance, motivation, and behaviour change

OBJECTIVES

This study aims to investigate treatment drop-out, and the associated roles of motivation, alliance, and behaviour change exhibited over the first four weeks of hospitalised treatment for anorexia.

METHODS

90 participants meeting DSM-IV criteria for anorexia nervosa completed questionnaires at admission, and four weeks into treatment. Weight data was collected over this same time period. At the end of treatment, participants were categorised into completer or premature termination groups.

RESULTS

The overall rate of premature termination was 57.8%. Those who prematurely terminated treatment demonstrated lower discharge BMI (p<.0005), and weight gain (p<.0005) than those who completed. Therapeutic alliance proved significantly different between outcome groups at admission (p=.004).

DISCUSSION

End-of-treatment outcomes for those who do not complete treatment are invariably poor. Therapeutic alliance appears to be a particularly important factor in this area.

Predictors of dropout from in-patient treatment of eating disorders: an Italian experience

INTRODUCTION

The aim of the study was to examine possible risk factors for dropout from in-patient treatment for eating disorders (ED).

MATERIALS AND METHODS

The present study consisted of a retrospective analysis of clinical and non-clinical available information about 186 patients suffering from ED consecutively admitted into the Villa Maria Luigia Private Hospital (Parma, Italy) in a three-year period (01/01/2006 - 31/12/2009). Sociodemographics, clinical history and current features, and results to the following psychometric instruments were analysed: Eating Disorder Questionnaire (EDQ), Predisposing, On-set and Maintaining risk factors list for Eating Disorders, Eating Disorders Inventory-II, Body Uneasiness Test and SCL-90.

RESULTS

Of the 186 patients, 46 (24.7%) voluntarily left the treatment program prematurely. Predictive factors included poor educational and professional achievements, parents' divorcing, parents' history of substance abuse and difficulties in interpersonal relationships.

DISCUSSION

Dropout is a multifactorial phenomenon with deep clinical consequences: the recognition of possible risk factors may support the choice of specific therapeutic strategies to improve the treatment of ED and its outcomes.

Why do people with eating disorders drop out from inpatient treatment?: the role of personality factors

Dropout rates from inpatient treatment for eating disorders are very high and have a negative impact on outcome. The purpose of this study was to identify personality factors predictive of dropout from hospitalization. A total of 64 adult patients with anorexia nervosa consecutively hospitalized in a specialized unit were included; 19 patients dropped out. The dropout group and the completer group were compared for demographic variables, clinical features, personality dimensions, and personality disorders. There was no link between clinical features and dropout, and among demographic variables, only age was associated with dropout. Personality factors, comorbidity with a personality disorder and Self-transcendence dimension, were statistically predictive of premature termination of hospitalization. In a multivariate model, these two factors remain significant. Personality traits (Temperament and Character Inventory personality dimension and comorbid personality disorder) are significantly associated with dropout from inpatient treatment for anorexia nervosa. Implications for clinical practice, to diminish the dropout rate, will be discussed.

Moderators of weight gain in the early stages of outpatient cognitive behavioral therapy for adults with anorexia nervosa

OBJECTIVE

Treatments for anorexia nervosa have relatively low levels of effectiveness. This prospective study examines the impact of patients' characteristics on their early responses to cognitive behavioral therapy (CBT) for anorexia nervosa.

METHOD

Patients' eating attitudes, body mass index, and comorbid characteristics at the outset of treatment were used to predict drop-out and changes in weight across the first 10 sessions of CBT. Forty anorexic patients (28 full syndrome and 12 atypical cases--body mass index range = 12.8-18.4) entered CBT for anorexia nervosa.

RESULTS

Early drop-outs (N = 6) had relatively low levels of anxiety at the beginning of therapy, but there were no other moderators. Weight gain was slower in the 6th to 10th sessions among patients with relatively unhealthy eating attitudes (restraint and shape concerns). Higher levels of anxiety at the start of treatment were associated with poorer weight gain across these first 10 sessions.

DISCUSSION

Early anxiety levels should be attended to closely in CBT for anorexia nervosa, with low levels indicating a high risk of drop-out and a greater need for engagement and motivational work, and high levels, indicating that clinicians should work explicitly with the patient on anxiety reduction techniques in order to enhance their level of early weight gain.

The level of associated depression and anxiety traits improves during weight regain in eating disorder patients

We assessed whether re-nutrition and weight gain have an influence on comorbid depression and anxiety in patients hospitalised for chronic eating disorders (ED). Seventy-five inpatients agreed to participate by completing the Eating Attitudes Test (EAT-40), the Beck Depression Inventory (BDI-13), and the State-Trait Anxiety Inventory (STAI-Y) before, during and after three months of treatment. Patients suffering from either anorexia nervosa or bulimia nervosa successfully regained weight during treatment. This weight gain was accompanied by statistically significant reductions in ED symptoms. Anxiety and, to a lesser extent, depressive symptoms diminished, but remained at pathological levels, with between diagnostic subtype differences. Improvement of depressive (r=0.77) and anxiety (r=0.64) levels were significantly (p<0.001) and positively correlated with the reduction of eating attitudes (EAT). These results are discussed in the context of re-orienting the therapeutic strategies aimed at reducing emotional suffering in patients with ED.

The efficacy of a brief motivational intervention for individuals with eating disorders: a randomized control trial

OBJECTIVE

Individuals with eating disorders are often ambivalent about recovery, and previous research has shown that readiness for change predicts enrollment in intensive treatment, symptom change, dropout, and relapse. Given the demonstrated importance of readiness for change, researchers and clinicians have turned to investigating interventions designed to enhance motivation. The purpose of this research was to determine the efficacy of Readiness and Motivation Therapy (RMT), a five-session individual preparatory intervention for individuals with eating disorders.

METHOD

Participants completed the Readiness and Motivation Interview and measures of eating disorder symptomatology, self-esteem, and psychiatric symptoms at intake. One hundred eighty-one participants were randomly assigned to the treatment (RMT) or wait-list control condition and were reassessed at 6-week and 3-month follow-up; 113 completed assessments at all three time points and primary analyses were based on these individuals.

RESULTS

Surprisingly, improvements in readiness for change, depression, drive for thinness, and bulimia symptoms occurred over time in both RMT and control conditions. However, at post and at follow-up, individuals who received RMT were less likely to have high ambivalence than were those from the control condition.

DISCUSSION

RMT may be of benefit to highly reluctant, clinically challenging patients and help them make better use of future, action-oriented treatment.

Predictors of dropout from inpatient treatment for anorexia nervosa: data from a large French sample

Dropout from anorexia nervosa inpatient treatment programs is frequent and is linked to a poorer outcome. This study aimed to identify predictive factors for dropout among anorexia nervosa inpatients. Between 1988 and 2004, 601 consecutive female inpatients with anorexia, restrictive (AN-R) or binge/purging (AN-B/P) subtype (Diagnostic and Statistical Manual of Mental Disorders, fourth edition (DSM-IV)), were assessed at admission (clinical, socio-demographic, and psychological data). A stepwise logistic model was developed. Dropout rates were respectively 50.0% and 56.2% for AN-R and AN-B/P. Seven predictive factors were identified in multivariate analysis: having one or more children, low desired body mass index (BMI), a low minimum BMI, high scores on the SCL-90 paranoid ideation and the Morgan and Russell eating behavior subscales, and low educational status. Early dropouts had a particular profile: lower desired BMI, higher score on SCL90 paranoid subscale, and more impulsive behaviors (alcohol use, suicide attempts). Dropout appeared as a multifactorial event. In clinical practice, certain factors could serve as warning messages reflecting the severity of the illness (high EDI score and low minimum BMI); while others could be targeted before hospitalization (having at least one child and low desired BMI).

A case series evaluation of the Maudsley Model for treatment of adults with anorexia nervosa

OBJECTIVE

Outpatient psychotherapy has been largely unsuccessful in assisting adults with anorexia nervosa (AN) to achieve weight restoration. The aim of the current study was to evaluate change and attainment of good and moderate outcome at 12-month follow-up using the Maudsley Model for Treatment of Adults with AN (MANTRA).

METHODS

Of 33 people assessed, 28 people commenced therapy, and 23 completed it (82%).

RESULTS

At post-treatment, seven people (30%) met the criteria for good outcome and one person met the criteria for moderate outcome. At 12-month follow-up, six people (26%) achieved good outcome, a further five achieved a moderate outcome, and there were significant improvements in body mass index, eating psychopathology and motivation, with large intention to treat effect sizes (ES) of 0.85, 1.19 and 1.57, respectively. Those people who dropped out of therapy were significantly more likely to binge or purge, and this behaviour was also associated with a moderate effect size (0.71) when examining differences between people who obtained good/moderate outcome versus poor outcome. Also predicting poor outcome status was lower baseline self-esteem and ineffectiveness.

CONCLUSION

Further evaluation of the use of MANTRA as an outpatient therapy for AN appears justified. Improvements to this therapy could include an early focus on binge and purge behaviour, as well as modules addressing low self-esteem and ineffectiveness.

Body dissatisfaction moderates weight curves in the inpatient treatment of Anorexia Nervosa

OBJECTIVE

To examine whether drive for thinness, body dissatisfaction, and restrictive/binge eating-purging subtype at admission moderates the weight curves of patients with Anorexia Nervosa (AN) over the course of inpatient treatment.

METHOD

The nature of weight curves, individual differences herein and moderating factors are examined in 92 AN patients by means of multilevel modeling.

RESULTS

The average weight curve of AN patients is characterized by a linear weight increase during treatment that levels off near the end of treatment. Substantial individual differences exist in the shape of patients' weight curves. Patients with stronger body dissatisfaction at admission display a slower linear rate of weight gain over the course of treatment. Neither drive for thinness nor restrictive/binge eating-purging subtype predicted patients' weight curve over the course of treatment.

DISCUSSION

Body dissatisfaction moderates patients' weight curves over the course of inpatient treatment but more research on factors determining weight curves is needed.

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.

Dropout from inpatient treatment for anorexia nervosa: critical review of the literature

OBJECTIVE

High dropout rates from inpatient treatment for Anorexia Nervosa (AN) pose a serious obstacle to successful treatment. Because dropping out of inpatient treatment may have a negative impact on outcome, it is important to understand why dropout occurs so that treatment can be targeted toward keeping patients in care. We therefore conducted a critical literature review of studies on dropout from inpatient treatment for AN.

METHOD

Searches of Medline and PsycINFO revealed nine articles on this subject. Two were excluded because they did not differentiate AN from other eating disorders in analyses.

RESULTS

Results were scarce and conflicting, with methodological issues complicating comparisons. Weight on admission, AN subtype, eating disorder symptoms, greater psychiatric difficulty in general, and the absence of depression were related to dropout in multivariate analyses.

DISCUSSION

Authors should use a common definition of dropout and continue research on the identified predictors as well as potential predictors such as impulsivity and family factors.

Factors associated with dropout from treatment for eating disorders: a comprehensive literature review

BACKGROUND

Dropout (DO) is common in the treatment of eating disorders (EDs), but the reasons for this phenomenon remain unclear. This study is an extensive review of the literature regarding DO predictors in EDs.

METHODS

All papers in PubMed, PsycINFO and Cochrane Library (1980-2009) were considered. Methodological issues and detailed results were analysed for each paper. After selection according to inclusion criteria, 26 studies were reviewed.

RESULTS

The dropout rates ranged from 20.2% to 51% (inpatient) and from 29% to 73% (outpatient). Predictors of dropout were inconsistent due to methodological flaws and limited sample sizes. There is no evidence that baseline ED clinical severity, psychiatric comorbidity or treatment issues affect dropout. The most consistent predictor is the binge-purging subtype of anorexia nervosa. Good evidence exists that two psychological traits (high maturity fear and impulsivity) and two personality dimensions (low self-directedness, low cooperativeness) are related to dropout.

CONCLUSION

Implications for clinical practice and areas for further research are discussed. Particularly, these results highlight the need for a shared definition of dropout in the treatment of eating disorders for both inpatient and outpatient settings. Moreover, the assessment of personality dimensions (impulse control, self-efficacy, maturity fear and others) as liability factors for dropout seems an important issue for creating specific strategies to reduce the dropout phenomenon in eating disorders.

Let eating disorder patients decide: Providing choice may reduce early drop-out from inpatient treatment

Premature drop-out from treatment is a highly prevalent phenomenon among eating disorder (ED) patients. In a specialized inpatient treatment unit a major change was made in the admission strategy in 2001, giving a maximum of personal choice to the patients. A quasi-experimental research was carried out comparing 87 patients treated till 2000 ('old' strategy) with 87 patients treated from 2001 on ('new' strategy). The results indicate that the provision of choice at the beginning of treatment significantly reduced drop-out during the first weeks of inpatient treatment. No differences between both strategies on later drop-out and weight change (in anorexia nervosa patients) during inpatient treatment were found. The results are discussed in the light of the importance placed on dynamics of personal choice, autonomy and volition within the framework of the self-determination theory (SDT).

Motivational change in an inpatient anorexia nervosa population and implications for treatment

OBJECTIVE

The relationship between motivation and recovery in anorexia nervosa has received increased attention in the research literature although few controlled investigations of increasing motivation in this population exist. Three questions were therefore examined in an inpatient anorexia nervosa population: (i) does baseline motivation predict change in eating pathology; (ii) does change in motivation predict change in eating pathology; and (iii) can we increase motivation to recover in this group?

METHOD

Inpatients (n=47) in a specialist weight disorder unit with a mean age of 21.85 years (SD=5.37) were randomly allocated to receive four sessions of motivational interviewing with a novice therapist in addition to treatment as usual (n=22) or treatment as usual alone (n=25). Assessment of eating pathology and motivation to recover was conducted on three occasions: at admission (baseline), and at 2- and 6 week follow up. Eating pathology was assessed using the Eating Disorder Examination and self-reported motivation was assessed using the Anorexia Nervosa Stages of Change Questionnaire and six Likert scales.

RESULTS

Higher baseline motivation across five of the seven measures predicted significant decreases in eating pathology, and increased Anorexia Nervosa Stages of Change Questionnaire scores between baseline and 2 week follow up predicted significant improvement in eating pathology between baseline and 6 week follow up. Significantly more patients were lost to follow up from the treatment as usual compared to the motivational interviewing group. More patients in the motivational interviewing condition moved from low readiness to change at baseline to high readiness to change at 2 and 6 week follow up.

CONCLUSIONS

Motivation is an important predictor of change in anorexia nervosa and preliminary evidence is provided that motivation can be improved in this population. Further investigations, however, of ways of improving motivation in this population need to be conducted, along with the impact of motivational changes on treatment outcome.

Predictive factors of length of inpatient treatment in anorexia nervosa

OBJECTIVE

To identify clinical variables influencing the length of stay (LOS) of inpatient treatment for anorexia nervosa (AN).

METHOD

We analyzed structured clinical charts of 300 consecutive hospitalizations for AN in a specialized eating disorder unit. The sample included patients from 12 to 22 years old. Factors related to the patient and events occurring during the stay were investigated as possible predictors of LOS.

RESULTS

Mean LOS was 135 days. The best model of linear regression revealed that the following factors were significantly related to LOS: duration of AN at admission, use of tube feeding during the stay, accomplishment of the therapeutic weight contract and presence of a comorbid disorder.

CONCLUSIONS

The identification of factors influencing duration of stay, both at the outset and during the hospitalization, could help clinicians to optimize and individualize treatments, as well as increase patient and family compliance.

Body attitudes in patients with eating disorders at presentation and completion of intensive outpatient day treatment

Due to the importance of the distorted body experience in eating disorder diagnosis and treatment, we wanted to explore body attitudes of patients with eating disorders before and after 5 months of intensive specialized outpatient day treatment. We assessed 193 patients diagnosed with Anorexia Nervosa (AN), Bulimia Nervosa (BN) and Eating Disorder Not Otherwise Specified (EDNOS) using the Body Attitude Test (BAT), Body Mass Index (BMI), Eating Disorder Evaluation Scale (EDES) and Symptom Checklist 90 (SCL-90). Eating disorder subtypes differed in BMI, total body attitudes and negative appreciation of body size at intake, but not at termination of treatment. Following treatment, all patient groups reported large improvements in eating disorder pathology and all but the AN-Restrictive (AN-R) group, reported large improvements in overall psychological functioning. The AN patients demonstrated significant improvement in BMI, however the Anorexia Nervosa purging (AN-P) and Anorexia Nervosa restrictive (AN-R) subtypes differed in their changes in body attitudes. AN-R patients indicated no significant improvement in body attitudes. AN-P patients improved in total body attitudes, except one subscale. Patients with Bulimia Nervosa non-purging (BN-NP) subtype, Bulimia Nervosa purging (BN-P) subtype and EDNOS demonstrated similar improvements in total body attitudes (BAT). Body attitudes provide important insights into differences between eating disorder diagnostic categories and their treatment responsiveness.

Overview of treatment modalities in adolescent anorexia nervosa

The aim of this article is to scrutinize and compare the benefits of distinct treatment settings for anorexia nervosa (AN) and to review the different treatment modalities that have proven helpful in the management of young patients with AN. Evidence-based findings on the effect of different treatment methods for AN are limited. Besides different treatment settings, a multimodal treatment approach comprising nutritional rehabilitation, nutritional counseling, individual psychotherapy and family-based interventions emphazising a group psychoeducation program for parents is presented.

Avoiding Conflict

Music therapy is an integral part of the inpatient treatment programme for young women with disordered eating at the Royal Children's Hospital in Melbourne. As part of ongoing clinical audit activities, an investigation was undertaken to analyse retrospectively the lyrics of young women who had participated in the music therapy programme. The purpose was to monitor and improve local clinical practice and clarify the specific contribution of music therapy to the diagnosis of anorexia nervosa. Results highlighted the role of mothers in the experiences of the young participants, with references to this relationship exceeding those to any other relationships. These findings are discussed in conjunction with an abandoned study where parental consent was not forthcoming for participation in a group music therapy research project. This article promotes a continuing awareness of the importance of the mother-daughter relationship in the treatment of eating disorders.

Readiness to change mediates the impact of eating disorder symptomatology on treatment outcome in anorexia nervosa

OBJECTIVE

The aim of the present study was to determine if readiness to change eating and weight was predictive of anorexia nervosa (AN) inpatient treatment outcome, and whether it mediates the relationships between AN treatment outcome and other known predictors of outcome.

METHOD

Participants were 127 patients with AN who were consecutively admitted to an intensive in-patient treatment program. They completed the Eating Disorder Inventory at admission and a measure of readiness to change after 4 weeks of treatment.

RESULTS

Readiness to change significantly predicted treatment outcome, even after controlling for level of eating disorder symptomatology at admission and AN subtype. It was also found to fully mediate the relationship between eating disorder symptomatology at admission and later treatment outcome.

CONCLUSION

These findings suggest not only that readiness to make changes is an important indicator of future inpatient treatment outcome, but that it is the mechanism by which eating disorder symptomatology predicts success in a treatment program.

Personality dimensions and treatment drop-outs among eating disorder patients treated with cognitive behavior therapy

Premature, unilateral interruption of inpatient treatment of eating disorders (ED) is a key factor limiting success. We evaluated the role of personality dimensions (temperament and character) in predicting drop-out in 145 consecutive ED inpatients (133 females) who entered cognitive behavior therapy. Baseline assessment included anthropometry, the Eating Disorder Examination, the Beck Depression Inventory, the State-Trait Anxiety Inventory, and the Temperament and Character Inventory (TCI). Treatment was based on the new transdiagnostic cognitive behavior theory of ED, adapted for an inpatient setting; it was manual-based and lasted 20 weeks (13, inpatients; 7, residential day hospital). Thirty-four patients (23.4%) discontinued treatment. Drop-outs had a lower level of education, a higher prevalence of separation or divorce in the family, and lower scores on the TCI Persistence scale. After correction for age, gender and body-mass index, scores on the Persistence scale continued to be significantly related to drop-out, and the association was confirmed by Kaplan-Meier analysis. Eating disorder patients with low Persistence scores are significantly less likely to complete inpatient treatment.
