Long-term outcome of children and adolescents with anorexia nervosa: study of comorbidity

Predictors for and duration of hospitalization among children and adolescents with eating disorders

OBJECTIVE

The objective of this study was to investigate the predictive value of sex, age, body mass index (BMI), Eating Disorder Examination (EDE) score, social risk factors, and psychiatric comorbidities for hospitalization and hospitalization duration among children and adolescents suffering from eating disorders.

METHOD

This prospective cohort study involved 522 consecutive patients who had been referred to a specialized eating disorder unit between January 1, 2009 and December 31, 2015; participants were followed up until August 1, 2016 by medical records. We used regression analyses to evaluate the prognostic value of sex, age, BMI, EDE, eating disorder diagnoses, social risk factors, and psychiatric comorbidities concerning inpatient hospitalization and hospitalization duration.

RESULTS

We found that younger age, higher EDE global score, lower BMI percentile, anorexia nervosa, a higher number of social risk factors, and the presence of diagnosed self-harm increased the odds of being hospitalized, while being female and having a comorbid autism spectrum condition increased the duration of hospitalization. No other psychiatric comorbidity was found to significantly predict hospitalization or duration of hospitalization.

DISCUSSION

The odds of being hospitalized were predicted by the severity of anorexia nervosa and indicators of social risk factors in the family, whereas the duration of hospitalization was predicted by having a comorbid autism spectrum condition, indicating a difference between the factors affecting the risk of hospitalization and the factors affecting the duration of hospitalization. This calls for further exploration of tailored treatments for eating disorders.

PUBLIC SIGNIFICANCE STATEMENT

This study finds that hospitalization for an eating disorder is predicted by the severity of the illness, self-harm, and social risk factors. Duration of hospitalization is predicted by having a comorbid autism spectrum condition. These findings indicate that the treatment of eating disorders may require different treatment approaches depending on the presentation of the individual patient to reduce both the need for hospitalization and the length of inpatient stay.

Evaluation of Insight, Self-Esteem, and Body Satisfaction in Eating Disorders

ABSTRACT

We investigated insight and its relationship with the clinical characteristics in eating disorders (EDs). Thirty anorexia nervosa (AN) and 30 bulimia nervosa (BN) patients, diagnosed based on Diagnostic and Statistical Manual of Mental Disorders , Fifth Edition criteria, were evaluated with Eating Disorder Examination Questionnaire (EDE-Q), the Body Image Satisfaction Questionnaire (BISQ), Rosenberg Self-Esteem Scale (RSES), and the Brown Assessment of Beliefs Scale (BABS). There was no statistically significant difference between the AN and the BN group in clinical scale scores. Thirty percent of AN and 23.3% of BN patients showed "poor insight" according to BABS. In the whole sample, BABS scores were significantly positively correlated with the EDE-Q eating, shape, weight concern subscales, and global scores, and the RSES scores; and negatively correlated with the BISQ general appearance and trunk subscale scores. Manifestation of "poor insight" is frequent in EDs. Poor insight in EDs is associated with eating, shape and weight concerns, body dissatisfaction, and low self-esteem.

Experiencing eight psychotherapy approaches devoted to eating disorders in a single-day workshop increases insight and motivation to engage in care: a pilot study

PURPOSE

For patients with eating disorders (EDs), early engagement in care is usually considered a positive prognostic factor. The aim of the study was to investigate how a single-day intervention devoted to early, brief, experiential exposure to a variety of psychotherapy approaches might support commitment to change and the decision to engage in care in patients with EDs.

METHODS

One hundred and sixty-nine adult outpatients newly diagnosed with an ED took part in a single-day workshop for groups of up to ten patients, where they experienced eight psychotherapeutic approaches. Motivation to change care and level of insight were assessed at baseline and 10 days after the intervention.

RESULTS

Motivation and commitment to take active steps toward change (expressed by the "Committed Action" composite score) significantly improved after the intervention (p < 0.001), and a significant number of patients specifically moved from "contemplation" to "action" stage (p < 0.001). The improvement of motivation to change was significantly associated with an increase in insight capacity (p < 0.001), and this increase was observed for almost all related dimensions such as recognition of illness or awareness of need for psychological treatment.

CONCLUSION

A single-day session devoted to experiencing a range of group psychotherapies increased patients' insight and motivation to actively engage in care. To confirm potential longer-term benefits of this intervention, further studies are needed to explore the contribution of each approach and process specifically involved in patients' increased motivation for care, as well as the clinical characteristics of patients associated with better outcomes.

Distinguishing delusional beliefs from overvalued ideas in Anorexia Nervosa: An exploratory pilot study

BACKGROUND

Characterised by the belief that more weight needs to be lost-despite emaciation, failing organs, medical instability and prospect of death-Anorexia Nervosa (AN) is a condition in which irrational, and highly-skewed, beliefs can be of delusional intensity. However, the nexus between delusion and rational awareness and how this is related to body image acceptance and perception has yet to be examined in AN. The current study aims to investigate the relationship between body dissatisfaction and beliefs of delusional intensity in an adult AN inpatient sample.

METHODS

Twenty-one adults (n_(women) = 20; n_(men) = 1), with a mean age of 27 years old (SD = 10), presenting for inpatient treatment for AN (ranging in severity from mild to severe; M_{(Body Mass Index)} = 17 kg/m²; M_{(Length of Stay)} = 22 days) participated in the study. Participants' dominant beliefs (related to AN) and level of insight (delusional; overvalued idea; or fair insight) were measured using either the Brown Assessment of Beliefs Scale (BABS) or the Nepean Beliefs Scale (NBS). The degree of body dissatisfaction was determined by examining the discrepancy between "perceived" and "ideal" body perception. To determine subjective and objective beliefs both the Contour Drawing Rating Scale (subjective) and computerised Body Image Assessment Software (objective) were used.

RESULTS

Almost one quarter (23.7%; n = 5) of participants appeared to have beliefs of delusional intensity related to their body shape (M = 27.4; SD = 23.03). Although a positive linear trend was indicated, there were no significant differences in body dissatisfaction scores between level-of-insight. Individuals whose belief was categorised as delusional were more likely to hold a negative affective body image state based on their ratings on the body image state survey when compared to the group who had good/fair insight (95% CI [0.53, 18.19]; p = 0.03).

CONCLUSIONS

The current exploratory pilot study concurs with others in the published literature that demonstrate that approximately 25 percent of participants with AN may have delusional ideas. The implications for treatment in similar samples warrant attention. Future research should also seek to understand the clinical significance of this delusional categorisation, the benefits of its utility in this population, and its relation to the severity of AN or stage of illness.

Impact of comorbid borderline personality disorder on the outcome of inpatient treatment for anorexia nervosa: a retrospective chart review

BACKGROUND

Data on patients with anorexia nervosa (AN) and comorbid Borderline personality disorder (AN+BPD) are scarce. Therefore, we investigated (1) whether patients with AN and AN+BPD differ in characteristics related to admission to, discharge from, and course of specialized inpatient eating disorder treatment and (2) how comorbid BPD affects treatment outcome.

METHOD

One-thousand one-hundred and sixty inpatients with AN (97.2% female, 5.9% with comorbid BPD; mean age = 26.15, SD = 9.41) were administered the Brief Symptom Inventory (BSI), the Eating Disorder Inventory 2 (EDI-2), and the Global Assessment of Functioning (GAF) at admission and discharge. Data were extracted by a retrospective chart review of naturalistic treatment data. Age, sex, weekly weight gain, length of stay, and discharge characteristics were compared with independent t-tests and χ2-tests. Changes in outcome variables, including body mass index (BMI), were analyzed with longitudinal multilevel mixed-effects models.

RESULTS

No differences in age or sex were found between patients with AN and AN+BPD, but groups differed in previous inpatient treatments, BMI at admission, and frequency of at least one additional comorbidity with higher values for AN+BPD. Higher levels of disorder-specific and general psychopathology at admission were found for AN+BPD. Patients with AN showed statistically significant improvement in all examined variables, patients with AN+BPD improved in all variables except EDI-2 body dissatisfaction. Strongest improvements in patients with AN+BPD occurred in BMI (Cohen's d = 1.08), EDI-2 total score (Cohen's d = 0.99), EDI-2 interpersonal distrust (d = 0.84). Significant Group x Time Interactions were observed for BSI GSI, GAF, and EDI-2 body dissatisfaction, indicating a reduced benefit from inpatient treatment in AN+BPD. At discharge, no differences were found in weekly weight gain, BMI, length of stay, or discharge characteristics (e.g., ability to work, reason for discharge), however, patients with AN+BPD were more frequently treated with medication.

CONCLUSIONS

Patients with AN+BPD differ from patients with AN in that they show higher general and specific eating disorder psychopathology and only partially improve under specialized inpatient treatment. In particular, aspects of emotion regulation and core AN symptoms like body dissatisfaction and perfectionism need to be even more targeted in comorbid patients.

Development and validation of the schedule for the assessment of insight in eating disorders (SAI-ED)

This study examined the reliability, validity and internal structure of the newly developed, interview-based Schedule for the Assessment of Insight in Eating Disorders (SAI-ED) and the relationships of insight with demographic and clinical characteristics in EDs. Ninety-four female patients - 44 with anorexia nervosa (AN) and 50 with bulimia nervosa (BN) - were assessed with SAI-ED. The Brown Assessment of Beliefs Scale was used to evaluate convergent validity of SAI-ED. Hierarchical cluster analysis and multidimensional scaling were used to identify insight components and assess their inter-relationships. The final 8-item SAI-ED demonstrated good psychometric properties. Inter-rater and test-retest reliabilities were high. Three subscales of SAI-ED were identified which measure major insight components: awareness of illness, awareness of symptoms, and treatment engagement. Patients with AN had significant lower score on SAI-ED than patients with BN. Impaired insight was associated with: (a) lower current and lowest lifetime BMI and more severe dietary restrain in AN, (b) illness duration, severity of overall ED symptoms, body-related concerns and obsessionality in BN. Insight is a multidimensional construct in EDs associated with different clinical aspects in AN and BN. The SAI-ED is a valid and reliable tool for the assessment of insight in EDs patients.

The impact of theory of mind and neurocognition on delusionality in anorexia nervosa

The current study aimed to examine the impact of theory of mind (ToM) deficits on body image delusionality in anorexia nervosa (AN) while accounting for the effect of other cognitive functions. ToM and other cognitive functions were assessed in 46 patients with AN and 42 healthy controls. We used the Brown Assessment of Beliefs Scale to assess the degree of delusionality of body image beliefs in AN patients. Delusional body image beliefs were identified in 26.1% and overvalued ideas in 30.4% of the AN patients. Moderate but significant associations were found between impairments in ToM-overall capacity, cognitive and affective components-and body image delusionality. The effect of overall ToM performance on delusionality remained significant after controlling for other cognitive factors. General intelligence was also significantly associated with delusionality. Our findings support the notion that difficulties in taking the perspective of others contribute to insight impairment in AN. Further investigation is required to examine the effect of failures in social cognition and metacognition on insight in AN.

Validation of a childhood eating disorder outcome scale

We developed and validated a childhood eating disorder outcome scale based on outcomes associated with body mass index standard deviation score (BMI-SDS). This prospective observational study included 131 children with eating disorders (aged 5-15 years). Participants' outcomes scales were completed at the first visit and at 1, 3, 6, and 12 months. The scale evaluated 12 outcomes: body weight change (BW), eating attitude (EA), fear of being fat (FF), body image distortion (BD), menstruation (ME), perceived physical condition (PC), attending school (AS), disease recognition by school (RS), family function (FA), disease recognition by parent (RP), social adaptation (SA), and relationships with friends (RF). Responses to all items were on a four-point Likert scale. Exploratory factor analysis was used to determine the number of factors based on the 12 outcomes. The relation between outcome scale scores and BMI-SDS over the 12-month follow-up period was analyzed. Two types of factors were extracted: disease-specific factors (EA, FF, BD) and biopsychosocial factors (BW, PC, AS, FA, SA, RF). Three items (ME, RS, RP) were excluded because they showed no significant loading effect. There was a significant negative correlation between the outcome scale and BMI-SDS, and changes in outcome scale scores from baseline to 12 months were significantly associated with improvement in BMI-SDS. We developed a childhood eating disorder outcome scale characterized by disease-specific and biopsychosocial factors. Biopsychosocial management combined with a therapeutic approach for disease-specific symptoms may support body weight recovery for children with eating disorders.

Short- and long-term outcome of males treated for anorexia nervosa: a review of the literature

PURPOSE

To give an overview of existing studies on the short- and long-term outcome for males treated for anorexia nervosa and to compare the outcome between adolescents and adults as well as between males and females.

METHODS

A systematic literature search was conducted in PubMed, PsycINFO and PSYNDEX and complemented by a manual search of the references from all relevant studies.

RESULTS

Out of 1064 search results, 18 studies met our inclusion criteria. A combined total of 1129 males of varying age groups were followed 0.5-27 years post-treatment. For 1009 individuals, only vital status was ascertained. Length of follow-up and outcome definitions varied considerably. Limited data-especially in adults-prevented adequate age comparisons. In both adolescents and adults outcome and mortality differed widely across studies with no firm evidence for gender differences. Outcome in mixed samples of adolescents and adults was inconsistent. Studies rarely compared the genders statistically, and when they did, the results were nonsignificant.

CONCLUSIONS

Knowledge on the outcome of males treated for anorexia nervosa is scarce. Only few studies comprising insufficient numbers of males exist. Results based on these findings are inconclusive and in part contradicting. Further research is needed, including large sample sizes of reliably diagnosed males, adequate follow-up intervals, follow-up assessments with carefully defined outcome criteria, and comparisons to matched female patient samples.

Symptomatology long-term evolution after hospitalization for anorexia nervosa: Drive for thinness to explain effects of body dissatisfaction on type of outcome

Anorexia nervosa (AN) is a serious psychiatric disorder associated with the highest mortality rate. Body dissatisfaction (BD) is now considered as an important risk factor for AN onset and relapse. Recent results lead to the hypothesis according to which AN and drive for thinness (DT) are related to body dissatisfaction. The primary aim of this current study was to identify whether DT mediated the relationship between BD and AN symptoms several years after hospitalization. As a secondary aim, self-reported Body Shape Questionnaire, Eating Attitude Test, Eating Disorder Inventory and Beck Depression Inventory scores were compared between the 48 women with a history of severe AN and 73 matched controls. A mediation analysis didn't show evidence of a direct effect of BD on eating disorder symptomatology after controlling for DT suggesting a full mediation of DT on the association between BD and eating disorders symptomatology. Results also showed that patients with a bad outcome had a higher score of DT than controls, which was not the case of patients with a good outcome. These findings highlight the potential importance of DT and the usefulness of targeting this dimension in therapeutic interventions for AN patients if further research confirm these results.

Long-term follow up of hospitalized pediatric anorexia nervosa restricting type

BACKGROUND

Information on long-term follow up of childhood-onset anorexia nervosa is scarce. This study investigated long-term (>10 years) course, outcome and prognostic factors for hospitalized childhood-onset anorexia nervosa restricting type (ANR).

METHODS

Forty-one ANR girls admitted to a single regional center participated. Median age at first admission was 13.3 years (range, 8.6-15.6 years). The longitudinal clinical course was retrospectively determined for a median follow-up period of 17.1 years (range, 10.4-21.1 years). We analyzed physical, psychological, and social variables to predict partial remission (PR) and full remission (FR).

RESULTS

The completion rate of follow up >10 years was high at 97%. At final evaluation (n = 38), distribution of prognosis was as follows: FR, n = 27 (71%); PR, n = 6 (16%); and non-remission, n = 5 (13%). The cumulative ratio of PR and FR increased during the first 5-6 years, and gradually reached a plateau at around 10 years. More than 10 years after the onset, one patient eventually achieved FR, and one patient died. Seven patients were rehospitalized and two died due to suicide during the entire follow up. On multivariate analysis, family disorders/problems rating score was a significant predictor of PR and FR.

CONCLUSIONS

This study included hospitalized ANR children aged ≤15 years, the youngest cohort ever reported. Long-term prognosis is generally favorable, but the mortality rate was 5%. Careful long-term follow up >10 years is needed to evaluate outcome of childhood-onset ANR, and family therapy is important in high-risk patients with family disorders/problems.

Treatment of Adolescents with Anorexia Nervosa

Research on the treatment of adolescents with anorexia nervosa is limited but shows that effective strategies employ a multidisciplinary team approach. Most patients receive medical attention when there is an acute medical or psychiatric emergency after losing a significant amount of weight and there is a need for nutritional and metabolic stabilization. Medical and nutritional stabilization are the first courses of treatment, followed by psychological stabilization. Initial treatment settings are dependent on the severity of symptoms and can range from inpatient to partial hospitalization or from day treatment to outpatient clinics. Physical activity and weight gain must be gradually accomplished. Effective treatment includes a variety of psychotherapeutic approaches (individuals and family therapy). Psychopharmacotherapy is generally unreliable in the treatment of anorexia nervosa and should be targeted to specific symptoms or complications. Prevention programs have been shown to have limited success.

Altered SPECT (123)I-iomazenil Binding in the Cingulate Cortex of Children with Anorexia Nervosa

Several lines of evidence suggest that anxiety plays a key role in the development and maintenance of anorexia nervosa (AN) in children. The purpose of this study was to examine cortical GABA(A)-benzodiazepine receptor binding before and after treatment in children beginning intensive AN treatment. Brain single-photon emission computed tomography (SPECT) measurements using (123)I-iomazenil, which binds to GABA(A)-benzodiazepine receptors, was performed in 26 participants with AN who were enrolled in a multimodal treatment program. Sixteen of the 26 participants underwent a repeat SPECT scan immediately before discharge at conclusion of the intensive treatment program. Eating behavior and mood disturbances were assessed using Eating Attitudes Test with 26 items (EAT-26) and the short form of the Profile of Mood States (POMS). Clinical outcome scores were evaluated after a 1-year period. We examined association between relative iomazenil-binding activity in cortical regions of interest and psychometric profiles and determined which psychometric profiles show interaction effects with brain regions. Further, we determined if binding activity could predict clinical outcome and treatment changes. Higher EAT-26 scores were significantly associated with lower iomazenil-binding activity in the anterior and posterior cingulate cortex. Higher POMS subscale scores were significantly associated with lower iomazenil-binding activity in the left frontal, parietal cortex, and posterior cingulate cortex (PCC). "Depression-Dejection" and "Confusion" POMS subscale scores, and total POMS score showed interaction effects with brain regions in iomazenil-binding activity. Decreased binding in the anterior cingulate cortex and left parietal cortex was associated with poor clinical outcomes. Relative binding increases throughout the PCC and occipital gyrus were observed after weight gain in children with AN. These findings suggest that cortical GABAergic receptor binding is altered in children with AN. This may be a state-related change, which could be used to monitor and guide the treatment of eating disorders.

Re-examining premature mortality in anorexia nervosa: a meta-analysis redux

Anorexia nervosa (AN) is reported to have the highest premature mortality of any psychiatric disorder, but recent meta-analyses may have inflated estimates. We sought to re-estimate mortality after methodological corrections and to identify predictors of mortality. We included 41 cohorts from 40 peer-reviewed studies published between 1966 and 2010. Methods included double data extraction, log-linear regression with an over-dispersed Poisson model, and all-cause and suicide-specific standardized mortality ratios (SMRs), with 95% Poisson confidence intervals. Participants with AN were 5.2 [3.7-7.5] times more likely to die prematurely from any cause, and 18.1 [11.5-28.7] times more likely to die by suicide than 15-34 year old females in the general population. Our estimates were 10% and 49% lower, respectively, than previously reported SMRs. Risk of premature mortality was highest in studies with older participants, although confounding by treatment was present. Gender, ascertainment, and diagnostic criteria also impacted risk.

Delusional versus nondelusional body dysmorphic disorder: recommendations for DSM-5

The core feature of body dysmorphic disorder (BDD) is distressing or impairing preoccupation with nonexistent or slight defects in one's physical appearance. BDD beliefs are characterized by varying degrees of insight, ranging from good (ie, recognition that one's BDD beliefs are not true) through "absent insight/delusional" beliefs (ie, complete conviction that one's BDD beliefs are true). The Diagnostic and Statistical Manual of Mental Disorders, 3rd ed., rev. (DSM-III-R) and The Diagnostic and Statistical Manual of Mental Disorders, 4th ed. (DSM-IV) classified BDD's nondelusional form in the somatoform section of the manual and its delusional form in the psychosis section, as a type of delusional disorder, somatic type (although DSM-IV allowed double-coding of delusional BDD as both a psychotic disorder and BDD). However, little or no evidence on this issue was available when these editions were published. In this article, we review the classification of BDD's delusional and nondelusional variants in earlier editions of DSM and the limitations of their approaches. We then review empirical evidence on this topic, which has become available since DSM-IV was developed. Available evidence indicates that across a range of validators, BDD's delusional and nondelusional variants have many more similarities than differences, including response to pharmacotherapy. Based on these data, we propose that BDD's delusional and nondelusional forms be classified as the same disorder and that BDD's diagnostic criteria include an insight specifier that spans a range of insight, including absent insight/delusional BDD beliefs. We hope that this recommendation will improve care for patients with this common and often-severe disorder. This increased understanding of BDD may also have implications for other disorders that have an "absent insight/delusional" form.

The neurocognitive basis of insight into illness in anorexia nervosa: a pilot metacognitive study

The primary goal of the present study was to explore the neuropsychological basis of insight into illness in anorexia nervosa by evaluating its differential and joint links with cognitive vs. metacognitive performance. Participants in the study were 25 women with anorexia nervosa (AN) and 25 healthy comparisons (HC). All participants completed a computerized version of the Wisconsin Card Sorting Task (WCST) and the Computerized Body-Size Discrimination task (CBSD). In addition to the standard administration of the tasks, subjects were also asked to rate their level of confidence in the correctness of each sort and to choose whether they wanted each sort to be "counted" toward their overall performance score on the test. Insight into illness in the AN group was assessed with the Scale of Unawareness of Mental Disorder (SUMD). Prediction of poor insight was significantly improved when adding the new, free-choice metacognitive measures to the conventional measures in both tasks, but not the other way around. These preliminary results suggest that metacognition might be an important mediator between basic cognitive deficits and poor insight and that it might be even more relevant to poor insight than cognitive deficits per se.

Psychometric evaluation of the Brown Assessment of Beliefs Scale in body dysmorphic disorder

The Brown Assessment of Beliefs Scale (BABS) is a widely used measure that assesses insight/delusionality-an important dimension of psychopathology-both dimensionally and categorically (e.g., delusional versus nondelusional). The BABS has been shown to have good psychometric properties in a number of disorders, but sample sizes were small. In the present study, 327 subjects with body dysmorphic disorder (BDD) were interviewed with the BABS to assess insight regarding appearance beliefs. Other measures were administered. Intraclass correlation coefficients demonstrated excellent interrater reliability and test-retest reliability; internal consistency was strong. Principal components factor analysis identified one factor accounting for 60% of the variance. Analyses with measures of severity of BDD, depressive symptoms, and general psychopathology indicated good discriminant validity. Among the treated subjects, the BABS was sensitive to change but not identical to improvement in symptom severity. These findings provide further evidence that the BABS is a reliable and valid measure of insight/delusionality.

Effectiveness of a multimodal inpatient treatment for adolescents with anorexia nervosa in comparison with adults: an analysis of a specialized inpatient setting : treatment of adolescent and adult anorexics

OBJECTIVE

There is evidence for an increased prevalence and an earlier onset of anorexia nervosa (AN) in adolescents. Early specialized treatment may improve prognosis and decrease the risk of a chronic course. The current study evaluates the effectiveness of a multimodal inpatient treatment for adolescent AN patients treated in a highly specialized eating disorder unit for adults.

METHOD

177 adolescents and 1,064 adult patients were included. The evaluation focused on eating behavior, depressive symptoms and general psychopathology.

RESULTS

All measured variables decreased significantly in both groups during inpatient treatment. No differences were found concerning weight gain, improvement of global eating disorder symptomatology as well as depressive symptoms. However, adults showed a higher psychological distress and in this regard also a greater improvement.

CONCLUSION

Results indicate that treating adolescent AN patients in a highly specialized eating disorder unit for adults can be an effective treatment setting for these patients.

The relationship between anorexia nervosa and body dysmorphic disorder

Anorexia nervosa (AN) and body dysmorphic disorder (BDD) are severe body image disorders that highly impair individuals in their daily functioning. They are discrete but overlapping nosological entities. In this review, we examine similarities between AN and BDD with regard to clinical, personality and demographic aspects, such as comorbidity, phenomenology, and treatment outcome. The review suggests that the two disorders are highly comorbid, and show similar ages of onset, illness trajectories, and comparable clinical and personality characteristics. However, important differences emerge in their responsiveness to psychosocial and psychopharmacological treatment, which are discussed. Clinical implications of these findings are summarized and directions for future research are delineated, with a focus on how current treatment components from each disorder may inform new interventions for both disorders.

Delusionality of body image beliefs in eating disorders

Preoccupation with body shape and weight is characteristic of both anorexia nervosa and bulimia nervosa. Despite their diagnostic and clinical significance, evidence on the nature of the underlying beliefs is relatively scarce. We used the Brown Assessment of Beliefs Scale (BABS) to assess the degree of delusionality of body image beliefs in seventy-two participants: 39 with anorexia and 33 with bulimia nervosa. We also investigated the relationship between body image delusionality and other clinical characteristics in eating disorders. Only patients with anorexia nervosa (28.8%) had delusional body image beliefs, whereas overvalued ideas appeared to be frequent in both anorexia and bulimia nervosa. Body image delusionality in anorexia nervosa was associated with restrictive eating pathology, early onset of the disorder and body dissatisfaction, whereas in the bulimia group it was linked to shorter duration of the illness, more intense dieting behaviors and specific psychological factors: ineffectiveness and maturity fears. Results suggest that a delusional variant of anorexia nervosa represents the one end of a continuum of insight among patients with eating disorders. Categorization of patients with eating disorders based on the level of delusionality of body image beliefs could facilitate further research on the role of insight deficits in these disorders.

Insight in eating disorders: clinical and cognitive correlates

BACKGROUND

The aim of this study was to explore the extent of lack of insight and its components in eating disorders (EDs) and to investigate the relationship between insight and clinical and cognitive characteristics in this group.

METHOD

Seventy-five participants were enrolled in the study: 25 with anorexia nervosa (AN), 15 with bulimia nervosa (BN) and 35 healthy controls (HC). Insight was assessed with a modified version of the Schedule for the Assessment of Insight for EDs (SAI-ED) and multi-dimensional scaling (MDS) analysis was used to clarify the internal structure of the scale. Neuropsychological tests included the Trail Making Test (TMT), the Brixton Test and a Verbal Fluency Task.

RESULTS

Only a subgroup of AN patients (24%) had severe impairment of insight. Patients with the restricting type of AN (AN-R) had poorer overall insight than patients with the binge-purge type of the disorder (AN-B/P). More of the ED patients displayed a deliberate denial of illness rather than a lack of awareness of the illness. A regression model revealed that only performance in part B of the TMT (TMT-B) was a moderate predictor of insight level. No association was found between insight and other cognitive or clinical variables.

CONCLUSIONS

Impaired insight is a significant feature of some ED patients. Insight in EDs seems to be partially dependent on intact mental flexibility.

A comprehensive meta-analysis of the risk of suicide in eating disorders

OBJECTIVE

Past meta-analyses on suicide in eating disorders included few available studies.

METHOD

PubMed/Medline search for papers including sample n ≥40 and follow-up ≥5 years: 40 studies on anorexia nervosa (AN), 16 studies on bulimia nervosa (BN), and three studies on binge eating disorder (BED) were included.

RESULTS

Of 16,342 patients with AN, 245 suicides occurred over a mean follow-up of 11.1 years (suicide rate=0.124 per 100 person-years). Standardized mortality ratio (SMR) was 31.0 (Poisson 95% CI=21.0-44.0); a clear decrease in suicide risk over time was observed in recent decades. Of 1768 patients with BN, four suicides occurred over a mean follow-up of 7.5 years (suicide rate=0.030 per 100 person-years): SMR was 7.5 (1.6-11.6). No suicide occurred among 246 patients with BED (mean follow-up=5.3 years).

CONCLUSION

AN and BN share many risk factors for suicide: the factors causing lower suicide rates per person-year in BN compared to AN should be investigated.

When have eating disordered patients recovered and what do the DSM-IV criteria tell about recovery?

Lack of consensus about criteria for recovery from eating disorders results in greatly varying percentages of recovered patients. Outcome studies not only use different criteria for recovery, but also quite different instruments, rendering their results incomparable. The same problem occurs among studies of predictors for recovery from eating disorders. Without consensus on criteria for recovery, it is not clear which goals of treatment are important to realize full recovery. In order to develop larger consensus on criteria for recovery, this study critically analyzes the most important outcome scores and the criteria for recovery deduced from the DSM-IV.

General psychopathology in anorexia nervosa: the role of psychosocial factors

The aim of the present study was to investigate psychosocial correlates of comorbid psychopathology. Data were collected from a total of 90 female inpatients with anorexia nervosa (AN). Higher levels of general psychopathology were detected in depression, interpersonal sensitivity, obsessive-compulsive and anxiety subscales of the Symptom Checklist (SCL)-90. Regression analysis also revealed that higher levels of psychopathology across SCL-90 subscales in AN patients are significantly associated with an earlier age of onset of the condition, higher levels of anorectic psychopathology as measured by Eating Disorders Examination, lower self-esteem as measured by Multidimensional Self-Esteem Inventory and social support levels as measured by Quality of Social Network and Social Support Questionnaire. Considering the high levels of general psychopathology in people with AN, routine clinical practice should aim for a comprehensive assessment of such. Given the strong association between psychosocial factors such as self-esteem, social support and general psychopathology, psychological therapies could play an important role in facilitating emotional recovery.

Suicidal behavior and depression in adolescents with eating disorders

BACKGROUND

Eating disorders are associated with an increased risk of suicide.

AIM OF THE STUDY

To examine suicidal behavior and depression in adolescents with eating disorders, and to identify risk factors associated with suicidal ideation and attempted suicide.

METHODS

Forty-six Israeli adolescent girls with anorexia nervosa or bulimia nervosa completed a self-report battery at the time of assessment or treatment. Suicide attempts and suicidal ideation were investigated in relation to clinical (e.g. body mass index, purging) and psychological (e.g. body dissatisfaction) features of the eating disorders, as well as depression. Twenty-four percent of the subjects had attempted suicide, and 65% reported suicidal thoughts. Fifty-eight percent were moderately to severely depressed.

FINDINGS

The risk of attempted suicide was associated with depression, a history of sexual abuse and longer duration of illness, but it was moderated by hospital treatment. Suicidal ideation was related only to depression.

CONCLUSIONS

The results of this study emphasize the importance of treating aggressively depression in adolescents with eating disorders. Depression seems to amplify illness severity. Currently, strategies for treating eating disorders focus more on the eating disorder behaviors and less on depression. We suggest investing more resources in detecting and treating the co-morbid depression.

Male eating disorders and therapy: a controlled pilot study with one year follow-up

OBJECTIVES

To examine whether outpatient treatment for male patients with bulimic symptomatology is as effective as it is for females.

METHOD

The outcome of 19 male patients was compared to that of 150 female eating disorder (ED) individuals after a group CBT treatment.

RESULTS

A reduction in ED symptomatology was observed after treatment for both genders. Main effects for gender indicated that after collapsing across the mean pre/post values, lower mean scores were found for men in the EAT-40, in the EDI-total score and in the following EDI subscales: "drive for thinness", "body dissatisfaction" and "interoceptive awareness".

CONCLUSIONS

A group CBT treatment appears to be effective for male and female ED patients.

Influence of overanxious disorder of childhood on the expression of anorexia nervosa

OBJECTIVE

Childhood anxiety often precedes the onset of anorexia nervosa (AN) and may mark a liability to the emergence of an eating disorder for some women. This study investigates the prevalence of overanxious disorder (OAD) among women with AN and explores how OAD impacts AN symptoms and personality traits.

METHOD

Participants were 637 women with AN who completed an eating disorders history, the Structured Clinical Interview for DSM-IV Axis I Disorders, and assessments for childhood anxiety, eating disorder attitudes, and associated personality traits.

RESULTS

Of 249 women (39.1%) reporting a history of OAD, 235 (94.4%) met criteria for OAD before meeting criteria for AN. In comparison to those without OAD, women with AN and OAD self-reported more extreme personality traits and attitudes and they engaged in more compensatory behaviors.

CONCLUSION

Among individuals with AN, those entering AN on a pathway via OAD present with more severe eating disorder pathology.

Specific and nonspecific comorbidity in anorexia nervosa

OBJECTIVE

This article reports lifetime Axis I and II comorbidity in women with anorexia nervosa (AN), and ascertains specific and nonspecific comorbidity in AN compared to clinical samples of women with bulimia nervosa (BN) or major depression (DEP).

METHOD

Outpatient AN (n = 56), BN (n = 132), and DEP (n = 100) samples were assessed using Structured Clinical Interviews I and II for DSM-III-R. Baseline data were compared using univariate statistics and logistic regression.

RESULTS

In the AN sample as a whole, specific elevations were found for prevalences of obsessive compulsive disorder. The AN-binge eating purging subtype (AN-BP) and the BN sample had elevated prevalences of Cluster B personality disorders. Cluster C prevalences were elevated across samples.

CONCLUSION

Evidence of AN-specific, eating disorder-specific, and nonspecific comorbidity illustrates the heterogeneity in AN. Further research is need to examine the relative impact of specific and nonspecific comorbidity in AN subtypes and AN as a whole.

Inpatients with eating disorders: demographic, diagnostic, and service characteristics from a nationwide pediatric sample

OBJECTIVE

This study describes the demographic and clinical characteristics of youth hospitalized with an eating disorder, using the Pediatric Health Information System (PHIS) database.

METHOD

Descriptive and inferential statistics were used to examine and compare PHIS inpatients (N = 1,713) with a primary discharge diagnosis of anorexia, bulimia, or eating disorder, not otherwise specified.

RESULTS

Of pediatric inpatients with eating disorders, 92% were female and 78% were non-Hispanic white. Their mean age was 15.3 years; 71% had anorexia; 68% had one or more comorbid psychiatric disorders; 53% stayed on a psychiatric unit; the mean length of stay was 15.7 days. Private insurance paid for 55% of hospital stays. Patients without private insurance were more likely than patients with private insurance to be Black or Hispanic and to have comorbid psychiatric diagnoses.

CONCLUSION

This study provides new information that can be used by hospitals to anticipate developmental and treatment needs of future inpatients with eating disorders.

Links between eating disorder symptom severity and psychiatric comorbidity

Patients with eating disorders (ED) frequently exhibit additional psychiatric disorders. This study aimed to examine whether psychiatric comorbidity in ED patients is associated with increased severity of ED symptoms in a sample of 277 women with a current ED (84 anorexia nervosa, 152 bulimia nervosa, 41 eating disorders not otherwise specified). Psychiatric comorbidity of Axes I and II was determined using the Structured Clinical Interview (SCID) for DSM-IV. Severity of ED-related symptoms was assessed using interviewer-rated scales from the Structured Interview for Anorexia and Bulimia Nervosa (SIAB). Affective and anxiety-related disorders of both axes were linked with increased intensity of weight- and appearance-related fears and concerns. Frequency of binge-eating and frequency of purging both were associated with Axis I anxiety disorders, substance-related disorders, and Cluster B personality disorders. Frequency of dieting was related to anxiety disorders on both axes. Multivariate analyses revealed that Axis I anxiety disorders were more closely linked with severity of ED symptoms than affective or substance-related disorders. The results showed that psychiatric comorbidity of both axes is linked with increased severity of ED symptoms and that there are associations between specific ED symptoms and specific forms of comorbidity.

Does the treatment of mental disorders in childhood lead to a healthier adulthood?

PURPOSE OF REVIEW

To review mechanisms by which intervention for childhood mental disorders may exert an influence on mental health and wellbeing in adulthood, the challenges to demonstrating long-term benefit or harm from such intervention, existing evidence of long-term benefit, and strategies for improving the long-term benefit of treatment.

RECENT FINDINGS

Intervention may improve long-term outcome through the promotion of protective interpersonal relationships, by enhancing scholastic and later occupational functioning, by arresting the progression of disorder, and by improving general health. Challenges to demonstrating benefits or harms in the long term include variability in the natural course of childhood mental disorders, heterotypic outcomes, and the influence of other variables over time on long-term functioning. Examples of demonstrated benefit include the lowering of risk for substance abuse seen with psychostimulant treatment for attention-deficit/hyperactivity disorder, improved outcomes for autism since the introduction of early interventions to address language impairment, and reduced mortality in anorexia nervosa.

SUMMARY

There are feasible enduring benefits of treatment for childhood mental disorders. Treatment of complex problems may have a greater long-term impact than in conditions that follow a benign natural course. Success requires more assertive approaches to treatment than are traditionally employed by child and adolescent mental health services.

A randomised controlled treatment trial of two forms of family therapy in adolescent anorexia nervosa: a five-year follow-up

BACKGROUND

There is growing evidence that family therapy is an effective treatment for adolescent anorexia nervosa. This study aimed to ascertain the long-term impact of two forms of outpatient family intervention previously evaluated in a randomised controlled trial (RCT).

METHOD

A five-year follow-up was conducted on a cohort of 40 patients who had received either 'conjoint family therapy' (CFT) or 'separated family therapy' (SFT). All patients were traced and 38 agreed to be reassessed (29 interviewed in person, 3 completed telephone interviews, 6 completed questionnaires and/or agreed for parents/GP to be interviewed).

RESULTS

Overall there was little to distinguish the two treatments at 5 years, with more than 75% of subjects having no eating disorder symptoms. There were no deaths in the cohort and only 8% of those who had achieved a healthy weight by the end of treatment reported any kind of relapse. Three patients developed bulimic symptoms but only one to a degree warranting a diagnosis of bulimia nervosa. The one difference between the treatments was in patients from families with raised levels of maternal criticism. This group of patients had done less well at the end of treatment if they had been offered conjoint family meetings. At follow-up this difference was still evident, as shown in the relative lack of weight gain since the end of outpatient treatment.

CONCLUSIONS

This study confirms the efficacy of family therapy for adolescent anorexia nervosa, showing that those who respond well to outpatient family intervention generally stay well. The study provides further support for avoiding the use of conjoint family meetings at least early on in treatment when raised levels of parental criticism are evident.

Outcomes of eating disorders: a systematic review of the literature

OBJECTIVE

The RTI International-University of North Carolina at Chapel Hill Evidence-based Practice Center systematically reviewed evidence on factors associated with outcomes among individuals with anorexia nervosa (AN), bulimia nervosa (BN), and binge eating disorder (BED) and whether outcomes differed by sociodemographic characteristics.

METHOD

We searched electronic databases including MEDLINE and reviewed studies published from 1980 to September, 2005, in all languages against a priori inclusion/exclusion criteria and focused on eating, psychiatric or psychological, or biomarker outcomes.

RESULTS

At followup, individuals with AN were more likely than comparisons to be depressed, have Asperger's syndrome and autism spectrum disorders, and suffer from anxiety disorders including obsessive-compulsive disorders. Mortality risk was significantly higher than what would be expected in the population and the risk of suicide was particularly pronounced. The only consistent factor across studies relating to worse BN outcomes was depression. A substantial proportion of individuals continue to suffer from eating disorders over time but BN was not associated with increased mortality risk. Data were insufficient to draw conclusions concerning factors associated with BED outcomes. Across disorders, little to no data were available to compare results based on sociodemographic characteristics.

CONCLUSION

The strength of the bodies of literature was moderate for factors associated with AN and BN outcomes and weak for BED.

Is anorexia nervosa a delusional disorder? An assessment of eating beliefs in anorexia nervosa

Anorexia nervosa (AN) is a serious mental illness, characterized in part by intense and irrational beliefs about shape and weight, including fear of gaining weight. Although these beliefs are considered to be a diagnostic criterion for the illness, they have not been systematically characterized. This study used the Brown Assessment of Beliefs Scale (BABS) to identify the dominant belief that interfered with eating in a sample of underweight patients with AN (N=25). The degree of insight was assessed quantitatively. The majority of participants (68%) spontaneously reported a dominant belief consistent with fear of gaining weight or becoming fat. Twenty percent of patients were categorized as delusional. The total score on the BABS was significantly correlated with the drive-for-thinness subscale of the Eating Disorders Inventory (EDI) (r=0.41, p=0.04), but did not correlate with overall measures of AN severity (body mass index [BMI], duration of illness, lowest BMI, other subscales of the EDI, or total EDI score). These findings highlight the centrality of fear of fat in AN and suggest the possibility that there is a subgroup of patients whose concerns about their weight reaches delusional proportions. This subpopulation of patients warrants further study, since patients with more delusional beliefs may have a form of AN that is more refractory to treatment.

Comorbidity studies of eating disorders and mood disorders. Critical review of the literature

OBJECTIVE

We conducted a critical literature review of studies assessing the prevalence of mood disorders (MD) in subjects with eating disorders (ED; anorexia nervosa and bulimia nervosa). In the first part of this article, we discuss methodological issues relevant to comorbidity studies between ED and MD. In the second part, we summarize the findings of these studies in light of the methodological considerations raised.

METHOD

A manual computerised search (Medline) was performed for all published studies on comorbidity between ED and MD. In order to have sufficiently homogeneous diagnostic criteria for both categories of disorders, this search was limited to articles published between 1985 and 2006.

RESULTS

Too few studies include control groups, few studies compared diagnostic subgroups of ED subjects, and results are scarce or conflicting.

DISCUSSION

The results are discussed in the light of the methodological problems observed. The implications when reviewing the results of published studies and planning future research are set out.

Outcome and prognostic factors for adolescent female in-patients with anorexia nervosa: 9- to 14-year follow-up

BACKGROUND

Earlier studies have indicated poor long-term outcomes for patients with anorexia nervosa.

AIMS

To study health and social outcomes of adolescent in-patients with anorexia nervosa in relation to prognostic factors.

METHOD

A register study based on based on socio-economic and health data was conducted for a national cohort of female residents in Sweden born between 1968 and 1977, including 748 in-patients with anorexia nervosa.

RESULTS

At follow-up 9-14 years after hospital admission, 8.7% of patients with anorexia nervosa had persistent psychiatric health problems demanding hospital care and 21.4% were dependent on society for their main income; the stratified relative risks were 5.8 (95% CI 4.7-7.6) and 2.6 (2.3-3.0) respectively, compared with the general female population. The mortality rate for patients with anorexia nervosa was 1.2% and the stratified risk ratio for maternity was 0.6 (95% CI 0.5-0.7). Long duration of hospital care and psychiatric comorbidity were predictors of persistent psychiatric problems and financial dependency on society.

CONCLUSIONS

The outcome in this cohort of adolescent in-patients with anorexia nervosa was considerably better than that reported in previous studies.

[Comorbidity between eating disorders and mood disorders: review]

OBJECTIVE

Comorbidity between eating disorders (ED) and mood disorders is a major issue when evaluating and treating patients with anorexia nervosa (AN) or bulimia nervosa (BN). In the literature, estimated comorbidity rates of mood disorders in subjects with ED differ widely across studies. Obviously, it is difficult to compare results from various sources because of differences in methods of assessment of depressive symptoms and in diagnostic criteria for both ED and mood disorders. Furthermore, few studies have included control groups, and, since mood disorders are among the most frequent psychiatric disorders in women--with an average estimated lifetime prevalence of 23.9 % (Kessleret al., 1994)--, it is not clear, yet, whether mood disorders are more common among women with an ED (AN or BN) than among women from the community. The only review articles we found on the relationships between ED and mood disorders survey different types of arguments in favour of a link between both categories of disorders, including symptoms, personal and family comorbidity, overlap in biological findings, and treatment results, but do not review in detail available comorbidity data. The aim of this paper is to conduct a critical literature review on studies assessing the prevalence of mood disorders in subjects with an ED (AN or BN). In the first part, we will discuss methodological issues relevant to comorbidity studies between ED and mood disorders, and select the most reliable studies. In the second part, taking into account these methodological considerations raised, we summarize the findings of these studies.

METHOD

We performed a manual and computerized search (Medline) for all published studies on comorbidity between ED and AD, limiting our search to the 1985-2002 period, in order to get sufficiently homogeneous diagnostic criteria for both categories of disorders.

RESULTS

Too few studies include control groups and few studies have compared diagnostic subgroups of ED subjects, with scarce or conflicting results.

DISCUSSION

We reviewed numerous studies here and conclude simply that there are many arguments in favor of elevated rates of MD in ED subjects, but there is no convincing evidence yet. Many questions are left unanswered or have conflicting responses. Our review highlights the need for further studies, which should address several requisites: comorbidity studies should be designed with this as a specific goal, rather than as a secondary aim within other types of studies (such as treatment studies, follow-up studies, etc.). Kendler et al. (1991) state that individuals with two disorders are more likely to present for treatment than individuals with one, therefore, comorbidity rates (which are not in agreement with a special etiologic relationship between BN and depression) may be exaggerated in clinical population results. New studies should include control subjects, matched (at least) for sex and age with ED subjects. Studies should evaluate prevalence of all types of MD in order to yield comparable estimates of MD in general. Comorbidity studies should be conducted on both current and recovered patients, compared to subjects from the community. It is still necessary to demonstrate specificity of findings, i.e. that early onset MD are of specific etiological importance to ED and do not simply increase the risk of later psychopathology in general. Studies should be conducted on larger samples, and all diagnostic subgroups should be considered (restrictive and bulimic anorexics, bulimics with and without history of AN, with or without purging). Multivariate comparisons should be performed, taking into account subject age, sex (if men are included), in- and outpatient status, course of illness, and other possibly relevant variables. Thus, more reliable estimates of the frequency of MD in subjects with ED could provide us with valuable etiologic, therapeutic and prognostic information.

Psychiatric comorbidities of female inpatients with eating disorders

OBJECTIVE

We analyze 27 point-prevalent DSM-IV Axis I comorbidities for eating disorder inpatients.

METHODS

The sample included 2436 female inpatients treated between January 1, 1995, and December 31, 2000, for primary DSM-IV diagnoses of anorexia, bulimia, and eating disorder not otherwise specified. Analyses were multivariate analysis of variance and multinomial logistic regression; sociodemographics and severity-of-illness measures were controlled.

RESULTS

Ninety-seven percent of patients evidenced > or = 1 comorbid diagnoses; 94% evidenced comorbid mood disorders, largely unipolar depression, with no differences across eating disorders; 56% evidenced anxiety disorders, with no differences across eating disorders; and 22% evidenced substance use disorders, with significant differences across eating disorders (p < .0001). Five specific diagnoses differed across eating disorders. Alcohol abuse/dependence was twice as likely with bulimia (p < .0001); polysubstance abuse/dependence three times as likely with bulimia (p < .0001); obsessive-compulsive disorder twice as likely with restricting and binge/purge anorexia (p < .01); posttraumatic stress disorder twice as likely with binge-purge anorexia (p < .05); schizophrenia/other psychoses three times more likely with restricting anorexia (p < .05) and two times with binge-purge anorexia (p < .05).

CONCLUSIONS

New findings emerged: extremely high comorbidity regardless of eating disorder, ubiquitous depression across all eating disorders, no difference in overall rate of anxiety disorders across eating disorders, greater posttraumatic stress disorder in binge-purge anorexia, more psychotic diagnoses in anorexia. Certain previous findings were confirmed: more obsessive-compulsive disorder in anorexia; more substance use in bulimia; and a replicated comorbidity rank-ordering for eating disorder patients: mood, anxiety, and substance use disorders, respectively.

Denial of symptoms and psychopathology in adolescent anorexia nervosa

OBJECTIVE

To evaluate the psychopathological status and denial of symptoms in a sample of 38 consecutively admitted adolescents with anorexia nervosa (AN).

METHOD

The Schedule for Affective Disorders and Schizophrenia for School-Aged Children was used to determine the categorical diagnosis of eating disorder. The anorexic adolescents completed the EAT-40 (Eating Attitude Test) and, on the basis of its score, the sample was dichotomized in a false-negative group (FNG) scoring under 30 and a positive group (PG) scoring over 30. We compared these two subgroups in terms of clinical variables (age of onset and admission, duration of illness prior to admission, diagnosis, BMI) and psychopathology assessed by the CBCL (Child Behaviour Checklist) and the YSR (Youth Self-Report). In order to evaluate the possible role of diagnosis and BMI on the EAT score we also dichotomized the sample with respect to the diagnosis (full vs. partial AN) and to the mean female BMI (< or = 15 vs. > 15).

RESULTS

A significant difference was found in terms of duration of illness prior to admission, which was briefer in the FNG. Higher CBCL and YSR values were found in the PG with significant differences in terms of YSR internalizing symptoms. A large amount of significantly positive Pearson's correlations were found between the CBCL and YSR values in the FNG. No significant Pearson's correlations were found between EAT, BMI and diagnosis.

CONCLUSIONS

The lower CBCL and YSR values in the FNG seem to point out a tendency of this group to deny anxiety and depression as well as an eating pathology; the longer duration of illness prior to admission in the PG seems to support the hypothesis that the PG may be considered to be not so much more disturbed as more aware of its eating attitudes and psychopathology. The nature of denial in anorexic adolescents is discussed.

Criteria for recovery from eating disorders according to patients and therapists

No consensus exists on criteria for recovery from eating disorders. Different criteria are used in effect and outcome studies, suggesting different rates of recovery. The questions for research were: Which criteria for recovery are important to ex-patients and therapists, and which criteria for recovery are actually realized by ex-patients? A list of 52 possible criteria for recovery was compiled from the literature on eating disorders, representing the domains of eating behavior, body experience, physical and psychological well-being, and emotional and social functioning. Ex-patients (n = 41) and therapists (n = 57) were asked to select criteria from this list, that they viewed as important for recovery from eating disorders. Ex-patients were asked which criteria they had realized by the end of their most recent therapy or treatment and in the period thereafter. Ex-patients and therapists agreed on most of the criteria for recovery. At the end of their therapy, more than 50% of the ex-patients had realized 44 of the criteria for recovery but thereafter they improved on 38 criteria. To realize full recovery and to prevent relapse, it is important to consider not only eating behavior and weight, but also psychological, emotional, and social criteria.

Treatment implications of Axis-II comorbidity in eating disorders

In this article, we review the clinical research on the implications of comorbid personality disorders (PDs), pathological personality traits, and the expression and response to treatment of those with eating disorders (EDs) (i.e., anorexia and bulimia nervosa, and binge eating disorder). Obsessive-compulsive PDs and related traits, such as perfectionism and rigidity, appear to be clear-cut risk and maintenance factors for anorexia nervosa. In bulimia nervosa, trait impulsivity seems to be related to early termination from therapy and, according to at least some indices, poorer responses to treatment. Dramatic-Erratic PD features, generally more characteristic of binge-purge ED variants, clearly predict a protracted course for general psychiatric symptoms, but may have less prognostic value for eating symptoms. Recent guidelines from two influential bodies--the American Psychiatric Association (APA, 2000) and the United Kingdom's National Institute for Clinical Excellence (NICE, 2004)--both include the concept that "trait-oriented" interventions, targeting personality-linked components like perfectionism, affective instability, impulsivity, and interpersonal disturbances, may optimize treatment effects. In general, the literature supports the recommendation that clinicians should apply well-validated, symptom-focused therapies for the EDs; in addition, clinicians may wish to incorporate trait-focused interventions in patients in whom personality pathology contributes to suboptimal response.

Emotional functioning in anorexia nervosa patients: adolescents compared to adults

Studies concerning eating disorder patients have revealed the presence of alexithymia, depressive, and anxiety disorders. We compared these aspects of emotional functioning in two groups of anorexia nervosa (AN) patients: adolescents vs. adults. Forty-eight adolescent anorexia nervosa patients (ADO) and 23 adult anorexia nervosa patients (ADU) completed a battery of tasks and questionnaires to measure these different aspects of emotional functioning and to control for differences of a more general cognitive nature. Both groups showed marked resemblance; both had high alexithymia scores and performed worse on emotional tasks measuring aspects of alexithymia. Furthermore, both groups showed high percentages of depressive and anxiety disorders, with the ADU group scoring only higher on specific and social phobia than the ADO group. Adult and adolescent AN patient groups do not differ substantially with respect to emotional functioning.

A two-factor model of disordered eating

General psychopathology (i.e., personality disturbance, mood/affect dysregulation) has been identified as common and perhaps etiologically important in eating disorder (ED) patients. In this context, we examined a two-factor model of disordered eating which implicated the independent and interactive contribution of (a) general psychopathology (personality) and (b) eating-related psychopathology (body esteem) in explaining deviant eating patterns. A sample of 266 female college/university students (M age=22.1) and 76 women with a clinically diagnosed ED (M age=28.09) completed paper and pencil questionnaires of deviant eating patterns, body esteem, and personality pathology. First, a K-means cluster procedure revealed a compelling three-cluster solution among the nonclinical women based on deviant eating variables: <<deviant eaters>>(n=61), <<restrainers>> (n=92), and <<nondeviant eaters>> (n=103). The ED women were classified as Cluster 4; <<clinical>> (n=76). Second, to evaluate our two-factor model, multinomial logistic regression (MLR) was used with cluster membership as the outcome variable and the following variables as predictors: body esteem, personality pathology, and all two-way interactions. In addition to several significant main effects, three interaction terms were marginally significant: Body esteem appearance x Narcissism (P=.047), Body esteem weight x Narcissism (P=.044), and Body esteem attribution x Stimulus seeking(P=.051). The overall extent of correct cluster classification was 63%. These results indicate that the presence of both low body esteem and maladaptive personality, and the interactive operation of these two factors, seems to contribute to the likelihood of having an eating disorder, beyond the independent contribution of either factor alone. Results are considered in the context of etiological models in which general psychopathology presents a vulnerability factor in ED development.

Psychiatric comorbidity and Eating Disorder Inventory (EDI) profiles in eating disorder patients

OBJECTIVE

This study examines potential overlaps between psychiatric comorbidity (Axis I and II) and scores on the subscales of the Eating Disorder Inventory (EDI) in women with eating disorders (EDs).

METHOD

In a sample of 248 women (72 with anorexia nervosa, 140 with bulimia nervosa, and 36 with eating disorders not otherwise specified), we determined psychiatric comorbidity using the Structured Clinical Interview for DSM-IV. Behavioural and psychological characteristics of EDs were quantified with the EDI.

RESULTS

Psychiatric comorbidity was high in both axes (74% for Axis I and 68% for Axis II). While most EDI subscales pertaining to psychological traits showed significant associations with Axis I and II disorders, the subscales concerning eating and perception of weight and shape were much less associated with psychiatric comorbidity. Affective and anxiety disorders, as well as personality disorders of clusters A and C, showed a similar pattern with links to most psychological subscales. The profile for substance-related disorders was different, showing associations with the Ineffectiveness and Interoceptive Awareness scales. Personality disorders of cluster B were related only to the Bulimia subscale and not to any of the psychological subscales.

CONCLUSIONS

The EDI appears to primarily reflect Axis I and II disorders related to affective and anxiety problems. Clinicians and researchers employing the EDI should be aware that it is not sensitive for all forms of comorbidity prevalent in ED patients.

Clinical course and short-term outcome of hospitalized adolescents with eating disorders: the success of combining adolescents and adults on an eating disorders unit

Although significant controversy exists regarding the appropriate setting for treating adolescents with eating disorders, empirical studies have been lacking. This study aimed to evaluate, and compare with adults, the clinical course and short-term outcome of adolescents with eating disorders hospitalized on an adult eating disorders unit. One hundred forty-four consecutive inpatient admissions on a weight gain protocol (28% minors and 72% adults) completed psychometric measures and were assessed on clinical indices. No differences between minors and adults were demonstrated for weight gain per week on either inpatient or partial hospitalization admissions. Whereas inpatient length of stay was equivalent, adolescents stayed significantly longer in partial hospitalization than adults. Minors did not differ from adults on the presence of problematic eating disordered behaviors or most psychometric measures, although they had less functional interference due to their eating disorders. Results suggest that an adult eating disorders specialty program can be an appropriate and efficacious setting for adolescents.

Outcome predictors in the short-term treatment of anorexia nervosa: an integrated medical-psychiatric approach

OBJECTIVES

Factors predicting clinical outcome in the short-term treatment of anorexia nervosa.

DESIGN

Longitudinal follow-up study.

SETTING

Department of Clinical and Experimental Medicine, "Federico II" University of Naples.

PARTICIPANTS

Fifty-eight young anorectic women consecutively attending the outpatient Unit between January 1997 and December 2000.

MAIN OUTCOME MEASURES

Body weight changes over six months' follow-up.

RESULTS

Body weight changes in the short term was exclusively predicted by the prevalent underlying psychiatric disorder, being increased in the patients with prevalently depressive traits, decreased in those with psychotic features and unchanged in those with a prevalently narcissistic personality.

CONCLUSIONS

The prevalent psychiatric disorder seems to predict clinical outcome in the short term. Body weight gain per se cannot always be the main target of medical intervention, at least in the early phase of the treatment of malnutrition secondary to major eating disorders.

What happens to eating disorder outpatients who withdrew from therapy?

OBJECTIVE

Dropouts are frequent among eating disorder (ED) patients, but less is known about their natural history. This paper assesses the outcome of outpatients who dropped out from a therapy programme and its possible causes.

MATERIAL AND METHODS

From 1992 to 1994, we assessed 222 ED subjects. Psychiatrists expert in EDs evaluated these subjects by defining baseline parameters and diagnosis was made according to the 3rd revisioned edition of the Diagnostic and Statistical Manual of Mental Disorders. One hundred and twenty-eight subjects (57%) dropped out during the treatment. In 1997, we contacted them, reassessed the same baseline parameters and asked for a self-judgment about their social and clinical condition during the previous 2-5 years. Patients were classified as "improved" and "not improved" (stationary or worse) according to their social, physical and psychological condition. The relation between baseline condition and outcome was determined statistically.

RESULTS

Seventy-one percent of subjects were "improved" and no deaths were recorded. A significant correlation was found between "duration of illness" and no treatment following a dropout.

DISCUSSION

The high percentage of improvement among dropouts was unexpected. Shorter duration of illness and lack of specific therapy in the improved patients suggest the existence of a subset of ED patients with acute onset and a spontaneous tendency to improve. This point obviously requires further investigation.
