The Bermond-Vorst Alexithymia Questionnaire cutoff scores: a study in eating-disordered and control subjects

BACKGROUND

The evaluation of alexithymic deficits has become increasingly desirable in health and psychopathology research. The purpose of this study was to calculate alexithymia cutoff scores for a recently developed self-report alexithymia questionnaire: the Bermond-Vorst Alexithymia Questionnaire Form B (BVAQ-B).

SAMPLING

Three hundred subjects (47 eating-disordered patients and 253 healthy individuals) completed the BVAQ-B and the 20-item Toronto Alexithymia Scale (TAS-20).

METHODS

The TAS-20 was used as a gold standard for this research, with its previously established cutoff scores serving as diagnostic criteria for determining the presence or absence of alexithymia. The BVAQ-B cutoff score selection was based on the examination of psychometric data (i.e., the sensitivity and specificity of the BVAQ-B scores and receiver operating characteristic curve analyses) and of clinical data (i.e., BVAQ-B mean score of the control subjects, who were mostly nonalexithymic, and BVAQ-B mean score of a group of patients with eating disorders, the majority of whom were alexithymic).

RESULTS

This research found that the most appropriate BVAQ-B cutoff scores for determining the absence and presence of alexithymia were 43 and 53, respectively.

CONCLUSION

In light of these findings, we believe that the BVAQ-B may also lend itself to a categorical evaluation of alexithymia, with these cutoff scores determining its absence or presence.

[Mood and anxiety disorders in relatives of anorexia nervosa patients: a review]

In the literature, no review concerning the family comorbidity of mood and anxiety disorders of anorexic subjects exists. However, this data can be important for the comprehension of this disorder and for the assumption of responsibility.

OBJECTIVE

We conducted a critical literature review on studies assessing the prevalence of anxiety disorders (AD) and mood disorders in relatives of anorexia nervosa (AN) subjects. In the first part, we discuss methodological issues relevant to these comorbidity studies. In the second part, taking into account the methodological considerations raised, we summarise the findings of these studies.

METHOD

We performed a manual and computerised search (Medline) for all published studies on the frequency of MD and AD in AN relatives and MD or AD, limiting our search to the 1980-2002 period, in order to get sufficiently homogeneous diagnostic criteria for both categories of disorders (most often RDC, DSM III, DSM III-R, or DSM IV criteria).

RESULTS

We review methodological issues regarding population sources, general methodological procedures, diagnostic criteria for AN, MD and AD, diagnostic instruments, age of subjects and course of the eating disorder.

DISCUSSION

We discuss the results taking into account the methodological problems observed. We give implications for reviewing the results of published studies and planning future research.

Resolving a disagreement in a clinical team: overcoming conflicting views about the role of family therapy in an outpatient treatment programme for anorexia nervosa

In the Adolescent Psychiatry Department at the Institut Mutualiste Montsouris, Paris, as is also observed in the literature, the outcome for anorexic patients can sometimes be catastrophic, regardless of treatments proposed. This disturbing finding led us to reassess our therapeutic treatment strategies, in an effort to improve patient outcome. The multidimensional treatment program implemented in the Department includes parent counselling, but not the whole family in a family therapy procedure. It has been demonstrated better outcome for patients who underwent family therapy in comparison to patients who underwent individual therapy. This raised the question of whether family therapy could improve our outpatient programme. This paper describes here how a research programme was developed to resolve a disagreement in our clinical team as to whether family therapy should be added to the existing care programme. The paper describes the difficulties encountered by our team, and the experimental design chosen to resolve the debate. Data will not be set out here.

[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.

Étude des relations entre alexithymie et anhédonie chez des femmes présentant des troubles du comportement alimentaire et chez des témoins

INTRODUCTION

Alexithymia and anhedonia both refer to a deficit in emotion regulation. Although these 2 concepts have been conceptualized to be closely linked, very few studies aimed at examining carefully their interrelations.

OBJECTIVES

Therefore, the purpose of the present study was to investigate the relationships between scores on alexithymia and anhedonia self-reports, and to assess whether the results were influenced by the presence of an emotional disorder.

LITERATURE FINDINGS

The 20-item Toronto Alexithymia Scale is the self-report most frequently used to assess alexithymia. Nevertheless, the results of recent studies comparing the psychometric properties of the TAS-20 and another alexithymia self-report - the Bermond-Vorst Alexithymia Questionnaire (BVAQ) - have recommended the BVAQ over the TAS-20.

DESIGN

Thus, both questionnaires were included in the present study. In addition, since depression and anxiety may influence the correlations between alexithymia and anhedonia scores, we also measured depression and anxiety and these scores were used to control for their potential confounding effect in the analyses. Two groups of participants were included in this study: 46 eating disordered female patients (ED) and 198 female control subjects. All the participants filled up the Bermond-Vorst Alexithymia Questionnaire-form B (BVAQ-B), the 20-item Toronto Alexithymia Scale (TAS-20), the Chapman and Chapman Social Anhedonia Scale (SAS) and Physical Anhedonia Scale (PAS), the 13-item Beck Depression Inventory (BDI) and the Spielberger State and Trait Anxiety Inventory (STAI-Y). The analyses consisted, first, in establishing the matrix of correlations between these self-reports total scores, using Pearson's coefficients of correlation. Then, TAS-20, BVAQ-B, SAS and PAS scores were correlated, adjusting for BDI and STAI scores, using partial correlation analyses. Mean scores comparisons according to the group of participants, and to the presence/absence of alexithymia, as well as to the presence/absence of anhedonia were performed using ANCOVAs or Mann-Whitney tests.

RESULTS

As predicted, BDI and STAI scores were found significantly and positively correlated with alexithymia and anhedonia scores in both participant groups. After controlling for depression and anxiety scores, TAS-20 and PAS scores remained significantly correlated, but not TAS-20 and SAS scores. BVAQ-B scores remained significantly correlated with PAS and SAS scores in the control group, but only with the PAS scores in the ED group. ED patients had higher alexithymia and anhedonia scores than the controls. In total, among the alexithymic individuals, 8.9% were social anhedonics, and 31.1% had a physical anhedonia. Conversely, among the participants with a physical anhedonia, two third were alexithymics. The same proportion of participants with a social anhedonia was alexithymic (66.7%).

CONCLUSION

The results of the present study are informed about the relationships between alexithymia and anhedonia. They also stress the need to rely on several alexithymia measurements, and they further demonstrate the necessity to compare the associations between different affect regulation dimensions in normal and psychopathological disorders.

Le contrat de poids lors d'une hospitalisation pour anorexie mentale

The weight contract is a traditional practice of the classical modalities of hospitalization of anorexics subjects. However, it is usually practised using different methods according to hospitals. It was explained on the theoretical side by our team but never exposed in its practical side. We propose to explain here in detail our practice of the weight contract. The information reported in this article is the result of articles review published by the professor Jeammet's team and of information resulting from meetings with experts of this team. First of all, we will expose the current context of care in the institut mutualiste Montsouris as well as the negotiation of the weight contract. Then, we will expose the method of care regarding somatic aspects, renutrition, body care, chemotherapy and family preoccupation. Lastly, we will explain in which situations the contract is sometimes renegotiated. In conclusion, we will summarize the utility of such a tool.

La dimension psychique de la sexualité des adolescents d'aujourd'hui

Sexuality, particularly during adolescence, involves personality as a whole. During puberty, which starts the process of adolescence, adolescents are faced with the fact they have not chosen their body which sends them back to the experience of passivity of childhood. It arouses in the most vulnerable adolescents what remains of expectations or affective dependence regarding their family circle, and thus they are confronted with that basic human paradox, i.e. to be oneself one has to accept to receive and to feed upon others and at the same time to be different from them. Such a fear of being dependent on others may lead adolescents to deprive themselves of what they expect to receive from others. Sexuality and the body, through the emotions they summon, are particularly subject to aggressive or rejection behaviours which characterize that age.

L’existence d’un épisode dépressif majeur est-elle liée à la présence de troubles anxieux chez les anorexiques et les boulimiques ?

The primaty objective is to determine whether the presence anxiety disorders is related to depressive comorbidity in subjects suffering from ED, while taking into account certain variables which may be related to depression [subjects' age, ED duration, prior incidents of anorexia nervosa in BN subjects, inpatient or outpatient status, nutritional state (as measured by Body Mass Index or BMI)]. Our secondary objective is to evaluate the relative chronology of the onset of anxiety disorders and depressive disorders in anorexic and bulimic subjects.

METHOD

We evaluated the frequency of depressive disorders in 271 subjects presenting with a diagnosis of either anorexia nervosa or bulimia, using the Mini International Neuropsychiatric Interview (MINI), DSM IV version.

RESULTS

While univariate analyses show that nearly all anxiety disorders are related to major depressive episode (MDE), a separate analysis of each anxiety disorder reveals that they do not all have the same influence in terms of risk of onset of MDE in anorexics and bulimics, when adjusted for univariate variables related to MDE (subjects' age, ED duration, prior incidents of anorexia nervosa in BN subjects, inpatient or outpatient status, nutritional state). Current generalized anxiety is significantly related to lifetime presence of MDE in AN subjects, and to current MDE in AN and BN subjects. Generalized anxiety is the most frequent disorder in AN and BN subjects to according our study; it also appears to be one of the principal predictive factors for MDE, which is 2.4 to 4.2 times more frequent when GAD is present. Diagnosis of OCD has its own particular effect on lifetime risk for MDE in AN subjects, regardless of GAD: it increases the risk of depression by 3.5. It is one of the most frequent anxiety disorders among AN subjects, present in nearly a quarter of them. In bulimics, when GAD is excluded, two factors are related to current diagnosis of MDE: panic disorder and subjects' inpatient or outpatient status. Hospitalized bulimics are diagnosed with current MDE 4.4 times more often than those seen as.

Validité du questionnaire d’alexithymie de Bermond et Vorst : étude chez des sujets présentant des troubles du comportement alimentaire et chez des témoins

Alexithymia core features are the difficulties in identifying and describing feelings; the difficulties in distinguishing feelings from the bodily sensations of emotional arousal; an impaired symbolization, as evidenced by a paucity of fantasies and other imaginative activity; and a tendency to focus on external events rather than inner experience. Several measures of alexithymia have been developed, including interviewer-rated questionnaires and self-report questionnaires. Among the self-report questionnaires, the 20-item Toronto Alexithymia scale (TAS-20) is the most commonly used, but it fails to measure all the core features of alexithymia. A recently developed instrument, the Bermond-Vorst Alexithymia Questionnaire (BVAQ), allows the measurement of the alexithymia core features, as well as an additional one. It appeared to present good psychometric properties, notably the abbreviated BVAQ-form B. The results of recent studies comparing the psychometric properties of the TAS-20 and the BVAQ have recommended the BVAQ over the TAS-20. However, this questionnaire needed further validation.

OBJECTIVES

Thus, the aim of the present study was to determine the convergent, discriminant and concurrent validity of the Bermond-Vorst Alexithymia Questionnaire -- form B (BVAQ-B) in a clinical sample of 59 eating disorder patients, as well as in 191 controls. The TAS-20 constituted the gold standard for the assessment of the BVAQ-B' convergent validity. To compare the concurrent validity of the BVAQ-B and the TAS-20, participants also completed several self-reports investigating different dimensions of emotion regulation capacities: the 13-item Beck Depression Inventory (BDI), the Spielberger State and Trait Anxiety Inventory (STAI-form Y), as well as the Chapman and Chapman Physical and Social Anhedonia Scales (PAS and SAS). One way analyses of variance were used for mean scores comparisons. Convergent validity was determined using Pearson coefficients of correlation.

RESULTS

Results of the analyses suggested the BVAQ-B has a satisfying convergent and discriminant validity. This was observed in both the clinical and control samples. Moreover, the comparison of the convergent validity of the BVAQ-B and the TAS-20 revealed several differences between these two alexithymia self-report questionnaires. The BVAQ-B appeared less sensitive to the subjective emotional state of the participants than the TAS-20. Whereas it was argued the TAS-20 overlaps with other emotional state scores, the BVAQ-B would allow to measure alexithymia more specifically. In addition, the present results allowed to further determine the relations between alexithymia and other dimensions of emotion regulation capacities. The analyses confirmed that alexithymia is linked to other emotion regulation dimensions such as depression and anxiety. Moreover, alexithymia was associated with physical and social anhedonia, two dimensions that received less interest in the alexithymia literature to date. This study also showed that control and clinical sample have different emotion regulation capacities. Eating disorder patients were not only more alexithymic and more depressed, but also more anxious and more anhedonic than the controls. Finally, this study revealed that alexithymia differs whether the alexithymic individuals are patients or controls. Healthy alexithymic individuals (ie, individuals categorized as alexithymic in the control group) seemed characterised by a selective deficit of emotional cognition, with sparing of emotional experience (Bermond's type II alexithymia). Alexithymics individuals of the eating -disorder group seemed particularly unabled to experience affect. This pattern could correspond to Bermond's type I alexithymia, which is characterised by the absence of emotional experience and, consequently, by the absence of the cognition accompanying the emotion. In summary, results of the present study add to the literature debating on whether alexithymia is similar in different types of population.

Psychoactive substance consumption in eating disorders

Research investigating the comorbidity between eating disorders and substance-use disorders have reported positive but contrasting results. The aim of this study was to further explore this association by studying patterns of consumption of the entire range of psychoactive substances (alcohol, specific drugs, prescribed psychotropics) in a large sample (N=271) of eating-disorder DSM-IV subtypes. Results show that subjects suffering from anorexia of the restrictive type show significantly less drug-consumption behaviors and alcohol abuse and/or dependence disorders than purging anorexic and bulimic subjects. No difference was found in the total consumption of psychotropics among the four groups of eating disorders. However, more than half of eating-disorder subjects are regular consumers of psychotropics. Among these regular consumers, bulimics self-prescribe and increase their doses of psychotropics significantly more than anorexics. Features of impulsivity that are associated with purging and bulimic behaviors could play a specific role in these patterns of comorbidity and account for such differences.

Obsessive compulsive disorders in eating disorders

OBJECTIVE

The aim of this study is to explore current and lifetime prevalence of obsessive compulsive disorders (OCD) in eating disorder (ED) subgroups and subtypes defined by the DSM-IV and to study the chronology of appearance of these disorders taking into account the role played by denutrition.

METHOD

Current and lifetime prevalence were investigated using the Mini International Neuropsychiatric Interview (MINI) and the Yale-Brown Obsessive Compulsive Scale in a sample of 89 DSM-IV ED patients (58 AN and 31 BN) and 89 matched controls.

RESULTS

Current and lifetime prevalence of OCD in ED was significantly higher than in general population (15.7% and 19% vs. 0% and 1.1%, P<.05). Anorexic patients presented a slightly higher current and lifetime comorbidity than bulimic patients (19% and 22.4% vs. 9.7% and 12.9%, n.s.). Purging anorexia was the diagnostic subtype, which presented the higher prevalences (29% and 43%), followed by restrictive anorexia (16%) and purging bulimia (13%). In the great majority of cases (65%), OCD diagnosis preceded ED diagnosis. Finally, OCD current prevalence and Y-BOCS scores of underweight patients were not significantly higher than normal-weight patients, suggesting that there were only limited links between denutrition and obsessionality.

Binge eating behaviours, depression and weight control strategies

The aim of this paper was to explore the relationships between depressive symptoms and weight control strategies in DSM-IV eating disordered patients with binge eating behaviours. We hypothesised that weight control strategies characterised by a loss of control, such as vomiting and purging, may be clinically associated with increased levels of depression. The study population consisted of 402 consecutive outpatients: 27 with binge eating/purging anorexia nervosa (AN-BN), 213 with purging bulimia nervosa (BN-P), 73 with non-purging bulimia nervosa (BN-NP), and 89 with binge eating disorder (BED). The severity of depression was measured using the Beck Depression Inventory (BDI), and binge eating behaviours were investigated using the self-report scale for bulimic behaviours. In the sample as a whole, the severity of depression significantly correlated with the severity of binge eating behaviours, but no significant differences were found in the severity of depression by diagnostic sub-types. In order to avoid the confounding erasing effect of time, a smaller sample of patients with a short history of binge eating behaviours was further explored. Furthermore, because weight control strategies and the eating disorder diagnostic sub-types overlapped imperfectly, the patients were compared on the basis of presence or absence of strategies reflecting an active attempt to master the weight gain due to bingeing behaviours. The patients adopting active control strategies (N = 14) had significantly less severe depressive symptoms than those adopting non-active weight control strategies (N = 39). Finally, the Authors discuss some hypotheses concerning the defensive role of weight control strategies and the impact of illness duration on the clinical expression of depression in eating disordered patients.

Involvement of cytokines in eating disorders: a critical review of the human literature

A number of findings from clinical and animal studies indicate that pro-inflammatory cytokines may play roles in eating disorders. The measurement of pro-inflammatory cytokines (IL-1, IL-6, TNFalpha), which are known to decrease food intake, provides highly variable data from which firm conclusions cannot be drawn. In most of the longitudinal studies where pro-inflammatory cytokines have been shown to be impaired in anorexia or bulimia nervosa, a return to normal values was observed after renutrition. However these findings do not exclude the possibility that pro-inflammatory cytokines might be overproduced in specific brain areas and act locally without concomitantly increased serum or immune production. It was also pointed out that the production of the major type-1 cytokines (especially IL-2) was depressed in anorexia nervosa. It remains unclear whether this is due to undernutrition or to a specific underlying cause common to eating disorders. The impaired cytokine profile observed in eating disorders could be related to several factors including impaired nutrition, psychopathological and neuroendocrine factors. More particular attention should be devoted to the deregulation of the anti/pro-inflammatory balance. Deregulation of the cytokine network may be responsible for medical complications in eating disorder patients who are afflicted with chronic underweight.

[Predictive factors in social adaptation disorders in anorexic and bulimic patients]

A lifetime diagnosis of at least one anxiety disorder has been found in 13% to 75% of women with BN (Herzog, Keller, Sacks, Yeh, & Lavori, 1992; Schwalberg, Barlow, Alger, & Howard, 1992), and in 20% to 55% of women with AN, (Herzog et al., 1992, Laessle et al., 1989). Wittchen et al., 1998) have observed that the frequency and degree of disabilities and impairments associated with mental disorders in adolescence are strongly related to comorbidity (notably with anxiety disorders). However, as noted by Wonderlich et al., 1997, no study has compared ED individuals with and without comorbid anxiety disorders in terms of clinical or general functioning. The current study was designed to determine whether social avoidance symptoms and/or comorbid lifetime anxiety disorders were predictive factors of social disability in subjects with ED (AN or BN). We focused on two main dimensions of social adaptation, regarding social and professional life. 63 subjects with anorexia nervosa or bulimia nervosa were assessed for lifetime diagnoses of anxiety disorders, childhood history of separation anxiety disorder, social avoidance symptoms, and social disability. Sociodemographic characteristics, lifetime diagnoses of ED and anxiety disorders, and ages at onset of each disorder present, were assessed using the French version of the Composite International Diagnostic Interview (CIDI) (Robins et al., 1988; WHO, 1990). In addition, childhood history of separation anxiety disorder, not included in the CIDI, was assessed using the appropriate section of the Schedule for Schizophrenia and Affective Disorders Lifetime Version--Modified for the study of Anxiety Disorders (SADS-LA-R) (Endicott, Spitzer, 1978; Mannuzza, Fyer, Klein, 1985). Social anxiety symptoms were measured on Liebowitz Social Phobia Scale (Liebowitz, 1987). Social adjustment was assessed using a semi-structured interview, the Groningen Social Disabilities Schedule-Second version (GSDS-II) (Wiersma, De Jong, Ormel, & Kraaij Kamp, 1990). For each of the two outcome variables regarding disability, the Social role and the Occupational role, all subsets logistic regression analysis was performed in accordance to Hosmer and Lemeshow's guidelines (Hosmer and Lemeshow, 1989). Our total sample of 63 subjects included 29 subjects with AN restricting type (27 women, 2 men; 7% with a past history of BN) and 34 subjects with BN purging type (all women; 53% with history of a previous episode of AN). On the Groningen Social Disabilities Schedule, 86% of the anorexics and 65% of the bulimics had disability regarding the "social role", and 86% and 61%, respectively, disability regarding the "occupational role". Using all subsets logistic regression analyses, predictive factors of disability were: 1) for the social role, social avoidance symptom score (p < 0.002) and diagnosis of separation anxiety disorder (p < 0.01); 2) for the occupational role, number of lifetime anxiety disorders (p < 0.01) and diagnosis of separation anxiety disorder (p < 0.06). The present study clearly demonstrates that social avoidance and anxiety disorders are common and important features in the clinical presentation of subjects with AN or BN, and that they can have a negative impact on both their social and their occupational adaptation. Chronicity is a major risk in the ED, in terms of medical and sometimes lethal complications, but also because of the social consequences of these disorders. It is therefore important, in subjects with ED, to identify comorbid conditions linked to social disability, in order to improve global outcome. Recognizing and treating comorbid anxiety disorders in subjects with AN or BN could give better results than treating only the ED, in terms of social as well as global psychopathological outcome.

Comorbidity between eating disorders and anxiety disorders: a review

OBJECTIVE

We conducted a critical literature review on studies assessing the prevalence of anxiety disorders (AD) in subjects with eating disorders (ED) (anorexia nervosa and bulimia nervosa). In the first part, we discuss methodological issues relevant to comorbidity studies between ED and AD. 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 from 1985-2001 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 discuss the results taking into account the methodological problems observed. We give guidelines for reviewing the results of published studies and planing future research.

Suicide attempts in women with bulimia nervosa: frequency and characteristics

OBJECTIVE

This study aimed to estimate the lifetime frequency of suicide attempts in a large referred population of women with DSM-IV bulimia nervosa (BN), and to compare demographic and clinical characteristics of those who had attempted suicide and those who had not.

METHOD

A total of 295 women (202 with BN purging type, 68 with BN non-purging type and 25 with anorexia nervosa binge/eating purging type) were assessed using a semi-structured interview and self-rated questionnaires.

RESULTS

Suicide attempts were frequent (27.8% of women), often serious and/or multiple. Women who had attempted suicide differed significantly from those who had not for earlier onset of psychopathology, higher severity of depressive and general symptoms, and more impulsive disordered conducts, but not for the core symptoms or severity of BN.

CONCLUSION

Interventions targeting depressive and impulsive features associated with BN are essential to reduce the risk of suicide attempt in women with this disorder.

[French validation study of the levels of emotional awareness scale]

According to a thesis based on the idea of an influence of cognitions in the structuring of internal reality, emotional awareness, ie the capacity of representing your own emotional experience and that of others, is a cognitive process that goes into maturation. Defining this concept, Lane and Schwartz present a cognitivo-developmental model in five stages of the processes of symbolization, accounting for the differences in levels of emotional awareness observed in individuals. The organization of these cognitive processes would thus be structured in well differentiated stages, in which the development of the emotions would be inseparable from the development of ego and of the relation to others. These authors focus on the capacity of representing in a conscious way the emotional experience and consider that verbal representations used to describe the contents of what is experience constitute a good reflection of the organization structural of the emotional awareness. Therefore, they worked out an instrument of evaluation: the Levels of Emotional Awareness Scale (LEAS), which measures the capacity to describe your own emotional experience and the one you allow to others, in an emotional situation. The system of quotation of this scale is based on the analysis of the verbal contents of the provided answers, in direct reference to the authors' theory of the levels of differentiation and integration of the emotional experience. It is therefore an empirical measurement which is centered specifically on the structural organization of the emotional experience. The various studies of validation of this instrument show that it presents solid metrological properties. This work presents the validation of the French version of Lane and Schwartz's LEAS. Validity and fidelity were studied in a group of 121 healthy subjects. This setting is part of a larger clinical evaluation, also including a collection of socio-demographic and clinical data, and other instruments of self-evaluation (Beck Depression Inventory, BDI, Hospital Anxiety and Depression Scale, HAD, and Toronto Alexithymia Scale, TAS). The face validity appears correct: the questionnaire was well accepted and seemed easy to complete. A principal components analysis of the correlation matrix of the set of items was used as the method of extraction of the various factors and made it possible to confirm the unidimensionality of the instrument. The number of factors to be retained was given according to Kaiser and Cattell criteria. The internal consistency was evaluated through computation of the Cronbach coefficient, whose value is 0.75 for the scale's global score. The confidence interval of the margin of error of LEAS scores was also measured; for the global score it is IC=[m 6.1]. The measure given by this rating scale may therefore be considered sufficiently accurate, since this interval is weak. A study of the frequency of quotation of each item of the instrument was carried out, in order to check the homogeneity and the uniformity of quotations, as well as a diagram of distribution of the score, showing that it follows a law which is close to a normal law. The concurrent validity could only be studied via the similar concept of alexithymia, measured with the TAS, for there is not other instrument validated in French evaluating the levels of emotional awareness, and these two instruments seem to measure different notions, because none of the correlations between the scores of these two questionnaires are significant. Concerning discriminant validity, the Pearson correlation coefficients between the global score for the LEAS, the BDI score and the HAD sub-scores for depression and anxiety were measured; it is clear that the level of emotional awareness is independent from negative affects. Furthermore, the study of the reliability made it possible to highlight excellent intra-class correlation coefficients (r=0.993). The French version of the Levels of Emotional Awareness Scale thus appears to be valid and accurate and should allow the study of levels of emotional awareness on psychopathology. It is about an easily acceptable and simple questionnaire of use in varied clinical circumstances.

Clinical relevance of electroconvulsive therapy (ECT) in adolescents with severe mood disorder: evidence from a follow-up study

Given the limited knowledge on the long-term outcome of adolescents who receive electroconvulsive therapy (ECT), the study aimed to follow-up adolescents treated with ECT for severe mood disorder. Eleven subjects treated during adolescence with bilateral ECT for psychotic depression (n = 6) or mania (n = 5), and ten psychiatric controls matched for sex, age, school level, and clinical diagnosis, completed at least 1 year after treatment a clinical and social evaluation. Mean duration between time of index episode and time of follow-up evaluation was 5.2 years (range 2-9 years). At follow-up: (1) all patients except two in the control group received a diagnosis of bipolar disorder. (2) Fifteen patients had had more than one episode of mood disorder. (3) The two groups did not differ in social functioning nor school achievement. (4) Impact on school achievement was related to the severity of the mood disorder rather than ECT treatment. The results suggest that adolescents given ECT for bipolar disorder, depressed or manic, do not differ in subsequent school and social functioning from carefully matched controls.

French classification for child and adolescent mental disorders

This report presents the French Classification of Child and Adolescent Mental Disorders (CFTMEA), operational since 1983 and validated through a broad multicentric study. CFTMEA is now the classification of reference for French child psychiatrists, who appear to be comfortable with it because it fits their diagnostic and therapeutic work. It bases its clinical categories on a psychopathological approach which includes an appraisal of potentials and prognosis. CFTMEA is deliberately built on two quite distinct axes: Axis I: basic clinical categories, and Axis II: associated and possibly etiological factors. The CFTMEA favors a broad appraisal of the disorders that it classifies, seeking whenever possible to establish a structural diagnosis based on psychodynamic psychopathology. The CFTMEA does not claim to be atheoretical, but does not impose a theoretical allegiance, because it is compatible with any etiological concepts. The CFTMEA's last revision (R 2000) is in an advanced phase of validation.

Factorial structure of the Sensation-Seeking Scale-Form V: confirmatory factorial analyses in nonclinical and clinical samples

OBJECTIVE

The factor structure of the Sensation-Seeking Scale (SSS)-Form V was studied in 2 large French samples, using confirmatory factorial analyses (CFA) to test the 4-dimensional model of sensation seeking postulated by Zuckerman.

METHOD

The study included 769 healthy subjects and 659 patients who met the DSM-IV criteria for substance use disorders or eating disorders and completed the SSS. The correlation matrices for each of the samples were analyzed using CFA.

RESULTS

In each sample, we found the 4-factor model to be replicable.

CONCLUSION

The multidimensionality of sensation seeking is supported by the results, and the 4-dimensional model of sensation seeking identified by Zuckerman can be explored in French-speaking people.

Electroconvulsive therapy in adolescents with mood disorder: patients' and parents' attitudes

The aim of the study was to assess retrospectively patients' and parents' experiences and attitudes towards the use of electroconvulsive therapy (ECT) in adolescence. The experiences of subjects (n=10) who were administered ECT in adolescence for a severe mood disorder and their parents (n=18) were assessed using a semi-structured interview after a mean of 4.5 years (range, 19 months to 9 years). Their attitudes were mostly positive and ECT was considered a helpful treatment. Concerns were frequently expressed, probably because ECT was not fully understood by the patients and their families. Most complaints were of transitory memory impairment. The parents were satisfied with the consent procedure, while all but one patient did not remember the consent procedure. We concluded that, despite negative views about ECT in public opinion, adolescent recipients and their parents shared overall positive attitudes towards the use of ECT in this age range.

[Current and lifetime prevalence of obsessive compulsive disorders in eating disorders]

A significant proportion of patients suffering from Eating Disorders (ED) present a comorbidity with anxiety disorders. Among the anxiety disorders, Obsessive Compulsive Disorders (OCD) are the third most frequently diagnosis observed in ED. However, prevalence rates from the literature are contradictory depending on the diagnostic criteria and evaluation tools used. Studies concerning the chronology of appearance of OCD and ED and the role played by denutrition are even rarer and equally contradictory.

OBJECTIVE

The aim of this study is to bring new empirical data to the study of the correlations between OCD and ED by exploring, in a significant clinical sample, the current and lifetime OCD comorbidity in the diagnostic sub-groups and sub-types of ED as defined by the DSM IV and to study the chronology of appearance of these disorders taking into account the role played by denutrition. We make the assumption that there should be a difference in the prevalence of obsessive compulsive disorders in the various ED sub-groups and sub-types and that purging anorexics should, at equivalent levels of denutrition, exhibit higher OCD prevalence rates than the other sub-types as a result of their more severe general psychopathology.

METHODS

Current and lifetime prevalence were investigated using the Mini International Neuropsychiatric Interview (MINI) and the Yale-Brown Obsessive Compulsive Scale in a sample of 89 DSM IV eating disorders in and out-patients aged between 15 and 30 (58 AN and 31 BN) and 89 matched controls. In order to increase the validity of the current diagnosis of OCD only patients presenting an OCD diagnosis on the MINI (excluding obsessions and compulsions related to food and body image) and a score of 16 or more on the Y-BOCS were included in the study.

RESULTS

Current and lifetime prevalence of OCD in ED is significantly higher than in general population (15.7% and 19% vs 0% and 1.1%, p < 0.05). Anorexic and bulimic patients do not show any difference in the current and lifetime comorbidity (19% and 22.4% vs 9.7% and 12.9%, ns). Concerning the diagnostic sub-types, following our assumption purging anorexics present the higher current and lifetime prevalences (29% and 43%), followed by restrictive anorexia (16%) and purging bulimia (13%). The only significant difference is found in the lifetime prevalence of OCD between purging and non purging anorexics. In the great majority of cases (65%) OCD diagnosis precedes ED diagnosis and OCD current prevalence and Y-BOCS scores of underweight patients are not significantly higher than normal weight patients, suggesting that there are only limited links between denutrition and obsessionality.

LIMITS

Some methodological limitations must be considered. First of all, the small sample size of the diagnostic sub-types of ED do not enable us to draw definitive conclusions concerning the prevalence of OCD in the clinical forms of ED. Some of the diagnostic sub-types of ED, as BN-NP, appear at different ages: in order to better investigate the prevalence of OCD in all the diagnostic sub-types, larger age ranges should be considered. Secondly, our sample of anorexics is almost made of hospitalized inpatients recrutated in a specialized university unit, whereas bulimics are all consulting outpatients. It is possible that the higher than normal rates of OCD in anorexics could be related to the severity of this sample. Comparisons with samples of consulting anorexics should be performed. Lastly, it is necessary to evoke the limitation represented by the choice of a healthy control group. OCD are rare in the general population and the differences found between the clinical and the control groups do not offer strong arguments to support the specificity of the association between OCD and ED, which would be better explored by using a pathological control group.

CONCLUSIONS

So far, none of the various models proposed to explain the comorbidity observed between ED and OCD appears completely satisfactory. ED and OCD would share a genetic vulnerability to a dysregulation of serotoninergic functioning which would predispose these subjects, depending on specific clinical and biological conditions, to develop an obsessional and compulsive symptomatology more or less focused on food and body image. The knowledge of the clinical and biological specificities of the ED diagnostic sub-types presenting an OCD comorbidity could point the way towards specific therapeutic interventions in these patients. Our study of the comorbidity of OCD in ED makes a further contribution to the identification of specific links between the OCD and the various clinical forms of ED. More clinical and biological studies are needed to further explore these relationships.

Eating disorders: psychodynamic approach and practice

In the psychodynamic approach we understand the defensive meaning of anorectic and bulimic conduct, and its value as a reorganizing of objective relations: difficulties in investing, antagonism between the objective inclination of these patients and the need to protect their narcissistic balance. The avoidance of depression linked to a compensatory juxtaposed narcissistic schema must be appreciated in order to understand the developing risks in these behaviours. The psychopathological significance of these behaviours, their stakes, and their therapeutic consequences are discussed.

Phenomenology, psychosocial correlates, and treatment seeking in major depression and dysthymia of adolescence

OBJECTIVE

To compare phenomenology, psychosocial correlates, and treatment seeking in DSM-Itt-R major depression and dysthymia among adolescents diagnosed as cases in a community-based study.

METHOD

A self-report questionnaire, including psychosocial data, life events, eating behaviors, depressive symptoms, substance use, pathological behaviors, and family and school functioning was administered to a nonselected sample (N = 3,287, 93.2% of targeted population) of adolescents aged 11 to 20 years from several Haute-Marne communities in France in 1988-1989. Subgroups of subjects (n = 205, 84.7% of eligible subjects) were interviewed with a structured diagnostic schedule, and adolescents with major depression (n = 49), dysthymia (n = 21) and controls (n = 135) were compared.

RESULTS

Nearly 30% of controls had at least one current symptom of depression. Patterns of affective symptoms were similar in major depression and dysthymia, but significant differences emerged in comorbid conditions (more anxiety disorders, suicidal behaviors, and alcohol intoxications associated with major depression) and stressor at onset (more severe in major depression). Experiences of loss during the prior 12 months were associated with both forms of affective disorder, while poor family relationships were specific correlates of dysthymia. In contrast, peer relationships and pathological behaviors did not differ between depressed subjects and controls. Although psychosocial functioning was significantly impaired in both groups of depressed adolescents, treatment seeking was limited to 34.7% for major depressive subjects and 23.8% for dysthymic subjects.

CONCLUSION

The results provide evidence that major depression and dysthymia in adolescence are equally severe but may have distinct patterns in associated factors. Despite free access to health care, the rate of treatment seeking for mood disorders in France is similar to that reported in U.S. studies.

Predictive factors of social disability in patients with eating disorders

OBJECTIVE

The study was designed to assess whether social avoidance symptoms and/or comorbid anxiety disorders were predictive factors of social disability in subjects with eating disorders.

METHOD

Sixty-three subjects with anorexia nervosa or bulimia nervosa were assessed for lifetime diagnoses of anxiety disorders, childhood history of separation anxiety disorder, social avoidance symptoms and social disability.

RESULTS

On the Groningen Social Disabilities Schedule, 86% of the anorexics and 65% of the bulimics had disability regarding the 'social role', and 86% and 61 % disability regarding the 'occupational role'. Using all subsets logistic regression analyses, predictive factors of disability were: (1) for the social role, social avoidance symptom score (p<0.002) and diagnosis of separation anxiety disorder (p<0.01); (2) for the occupational role, number of lifetime anxiety disorders (p<0.01) and diagnosis of separation anxiety disorder (p<0.06).

DISCUSSION

Recognizing and treating comorbid anxiety disorders in subjects with eating disorders could improve social adaptation and global psychopathological outcome.

Cytokines and anorexia nervosa

OBJECTIVE

Recent studies have indicated that the inflammatory cytokines could be implicated in anorexia nervosa and in its complications. To determinate the potential role of interleukins (IL-1, IL-2, IL-4, IL-6, IL-10), interferon (IFN gamma), tumor necrosis factor (TNF-alpha), and transforming growth factor (TGF-beta2) in anorexia nervosa, serum concentrations of these cytokines were measured in patients suffering from anorexia nervosa in comparison to healthy subjects.

METHOD

Twenty-nine anorexic women according to DSM-IV criteria participated in the study. The control group consisted of 20 healthy women without eating disorders, mood disorders, and immunological disorders.

RESULTS

We find that serum IL-2 and TGF-beta2 concentrations were both significantly decreased in anorexic patients, although the other cytokines did not differ significantly between the two groups.

CONCLUSION

Our results show that in patients with anorexia nervosa, there are lower levels of specific cytokines (especially IL-2 and TGF-beta2). These levels may reflect the combination of impaired nutrition and weight loss, therefore, the dysregulation of these cytokines may contribute in anorexia's complications. Follow-up studies should examine the effects of parameters such as starvation, psychopathologic factors, and psychoneuroendocrinological perturbation which could affect interplay between cytokines, neuropeptides, and neurotransmitters.

Factorial structure of the 20-item Toronto Alexithymia Scale: confirmatory factorial analyses in nonclinical and clinical samples

OBJECTIVE

The 20-item Toronto Alexithymia Scale (TAS-20) measures three intercorrelated dimensions of alexithymia: (1) difficulties identifying feelings (DIF), (2) difficulties describing feelings (DDF), and (3) externally oriented thinking (EOT). The aim of the study was to test the three-factor model of the TAS-20 using confirmatory factorial analyses (CFA).

METHOD

769 healthy subjects and 659 patients meeting the DSM-IV criteria for substance use disorders or eating disorders completed the TAS-20. The correlation matrices for each of the samples were analyzed with LISREL 7.16.

RESULTS

In each sample, the three-factor model was found to be replicable.

CONCLUSION

The three TAS-20 subcales can be used to explore the distinct facets of the alexithymia construct.

[Psychoactive drug use in a declared non-addicted control sample and comorbidity. Results of a study in 860 French-speaking subjects]

AIMS

This study, conducted within the framework of a broader research program of the INSERM 494013 Dependence Network, was designed to estimate illicit drug use and tobacco smoking in a declared non-addicted sample and to determine whether illicit drug users differ from non-users in terms of comorbidity.

METHODS

The study was conducted in an "all and sundry" sample of subjects. Patterns of drug use and comorbid factors (psychiatric disorders, suicide attempts, repeated accidents, social inadaptation) were assessed using a semi-structured interview (heteroevaluation, MINI DSM IV interview, Gröningen).

RESULTS

Among 860 subjects, 107 (12.4%) used illicit drugs and 26 of these 107 (24.3%) were dependent users or abusers. Specific analysis of non-dependent non-abuser subjects who had used illicit drugs (70 occasional and 11 regular users) showed a higher rate of use in younger subjects (12.7% in the 15-24 year group, 5.7% in the 24-49 year group) and men. Except for repeated accidents (OR=5.5 [1.6-18.5]), comorbid disorders were not more frequent in non-users than in users.

CONCLUSION

Besides use for recreational purposes, the rate of use of illicit drugs with abuse or dependence was high in our non-clinical sample. Although no specific comorbid psychiatric disorders were identified among non-dependent non-abuser subjects who had used illicit drugs, the frequency of repeated accidents evidenced the ill-fated side effects of illicit drugs and/or the specific biopsychological vulnerability of these subjects. This highlights the importance of not neglecting drug abuse.

[Pertinence of the addiction concept in eating behavior disorders]

From a psychodynamic perspective, dependence disorders, irrespective of the object of addiction, can be seen as the expression of the subject's neurobiological, psychopathological, cultural and social vulnerability. Since vulnerability strengthens and reorganizes the personality, it can drive these subjects to perpetuate pathological behaviors. In this light, behavior disorders belong to the field of addiction diseases, especially considering that the underlying psychopathological structures are close to those observed in addiction, that depression plays a central role, and that their development into toxic addictive behavior (drugs, alcohol, psychotrope) is frequent.

[Alexithymia and depression in eating disorders]

Patients suffering from eating disorder show elevated rates of alexithymia and depression. We compared alexithymia and depression ratings for non-hospitalized women meeting DSM IV criteria for anorexia nervosa (n = 32) and bulimia nervosa (n = 32) to healthy women (n = 74). Alexithymia was evaluated by the Toronto Alexithymia Scale (TAS-20) and depression by the Hospital Anxiety and Depression Scale (HAD). We found that TAS and HAD scores were significantly higher in anorexic compared to bulimic patients, although alexithymia and depression, as evaluated, were significantly and positively correlated with each other (r = 0.53, p = 0.001). Finally, a logistic regression with alexithymia and depression as independent variables showed a strong correlations between the HAD ratings and anorexia, but no correlations between TAS score and the eating disorder subgroups. In eating disorder patients, alexithymia, as evaluated by the Toronto Alexithymia Scale, seems to exhibit a thymo-dependent component which could be secondary to concurrent depression. Through recent studies and results of our research, we analyze and give several interpretations which may explain this correlation between alexithymia and depression.

Early psychopathological signs in bulimia nervosa. A retrospective comparison of the period of puberty in bulimic and control girls

While bulimia nervosa (BN) typically begins in girls during late adolescence, puberty and associated developmental changes have been linked to negative body image and onset of a variety of psychological problems. This study aimed to identify early psychopathological signs, which could have marked the period of puberty in subjects whom later developed BN. In a case control study, we compared 49 girls with BN according to DSM-IV, aged between 18 and 20 years, to 49 girls of the same age, who were free of any past or current psychiatric diagnosis. Psychiatrists or clinical psychologists, using a semi-structured clinical interview including retrospective assessment of the emotional and behavioural changes that had occurred in puberty evaluated both groups. Before the onset of a clinical eating disorder, the subjects with BN presented significantly more often than controls weight related concerns, attitudes of withdrawal and social isolation, and negative changes in their body image and self-image, as well as in their relationships with siblings and peers. The results suggest that early psychological distress precedes the onset of an eating disorder in many cases, and that prevention efforts should be directed towards peripubertal psychopathology.

Alexithymia and depression in eating disorders

We compared alexithymia and depression ratings for non-hospitalized women meeting DSM-IV criteria for anorexia nervosa (n=32) and bulimia nervosa (n=32) to ratings for healthy women (n=74). Alexithymia was evaluated by the Toronto Alexithymia Scale (TAS-20) and depression by the Hospital Anxiety and Depression Scale (HAD). TAS and HAD scores were significantly higher in anorexic compared to bulimic patients, although these two scales were significantly and positively correlated (r=0.53, P=0.001). After taking depression into account as a confounding variable, rates of alexithymia did not vary according to the type of eating disorder (anorexia or bulimia).

Absence of cognitive impairment at long-term follow-up in adolescents treated with ECT for severe mood disorder

OBJECTIVE

Cognitive functions of adolescents treated with ECT for mood disorder were evaluated at long-term follow-up.

METHOD

At an average of 3.5 years (SD=1.7) after the last ECT, 10 subjects treated during adolescence with bilateral ECT for severe mood disorder completed a clinical and cognitive evaluation, including the California Verbal Learning Test and Squire's Subjective Memory Questionnaire. The same assessments were given to 10 psychiatric comparison subjects matched for sex, age, and diagnosis.

RESULTS

All cognitive test scores of the patients treated with ECT were similar to those of the comparison subjects and did not differ from norms from the community. Six of the 10 ECT-treated patients reported having had memory losses immediately after the ECT course, but only one complained of subjective memory impairment at follow-up.

CONCLUSIONS

The results suggest that adolescents given ECT for severe mood disorder do not suffer measurable cognitive impairment at long-term follow-up.

Anxiety disorders in anorexia nervosa and bulimia nervosa: co-morbidity and chronology of appearance

The objectives of the study were to assess lifetime prevalence of specific anxiety disorders, and their age of onset relative to that of eating disorders (ED), in a French sample of patients with anorexia nervosa (AN) or bulimia nervosa (BN). We assessed frequencies of seven anxiety disorders and childhood histories of separation anxiety disorder among 63 subjects with a current DSM-IV diagnosis of an ED, using the Composite International Diagnostic Interview (CIDI). Eighty-three percent of subjects with AN and 71% of those with BN had at least one lifetime diagnosis of an anxiety disorder. By far, the most frequent was social phobia (55% of the anorexics and 59% of the bulimics). When present, the co-morbid anxiety disorder had predated the onset of the ED in 75% of subjects with AN, and 88% of subjects with BN. Our results are consistent with those of studies conducted in other countries, and show that an anxiety disorder frequently exists before an ED. This has to be taken in consideration for successful treatment of patients with AN or BN.

Obsessive-compulsive symptoms as a correlate of severity in the clinical presentation of eating disorders: measuring the effects of depression

Obsessive-compulsive symptoms have been related to severity in the clinical presentation of eating disorders, whereas the impact of depression on the correlations between their severity and the severity of eating disorders has not been investigated. This paper assesses the effects of depression in 42 adolescent patients who met DSM-IV criteria for anorexia nervosa or bulimia nervosa by using the Yale-Brown Obsessive Compulsive Scale (Y-BOCS), the Eating Disorder Inventory (EDI) and the Beck Depression Inventory (BDI). The results indicate that patients who show elevated obsessionality and compulsivity on the Y-BOCS display a significantly higher degree of disturbed attitudes and behaviours concerning eating than patients with limited obsessionality and compulsivity. However, when the effects of depression are considered, all the differences found disappear. Our study suggests that depression is more directly associated with the severity of eating disorders than obsessive-compulsive symptoms and that the intensity of obsessive-compulsive symptoms in eating disorders is influenced by the intensity of depression. The relations between obsessive-compulsive symptoms, depression and eating disorders are not known. Even so this study highlights the importance of assessing depression when using obsessive and compulsive symptoms as a correlate of severity in the clinical presentation of eating disorders.

Bulimia nervosa and autoimmunity

The autoantibodies that react with dopamine and serotonin are of interest in the study of bulimia nervosa. These neurotransmitters play an important role in appetite control, sexual and social behavior, and stress responses, all of which form a part of the clinical picture of bulimia nervosa. Are these autoantibodies involved in the serotoninergic hypofunctioning present in bulimia nervosa? Are they a part of an immunity regulation system essential for the cerebral system's homeostasis? To address these questions, 31 bulimic females (diagnosed according to DSM-III-R criteria) were compared with 10 control subjects (matched to the patients for sex, age, and demographic/psychosocial features). Measurement of the activity of natural autoantibodies reacting with dopamine, dopamine-beta-hydroxylase and serotonin was performed by an enzyme-linked immunosorbent assay (ELISA) for typical immunoglobulins (IgG, IgM, IgA). All of the autoantibodies of the IgG type were lower in the bulimic group than in the control group, a difference that was statistically significant for IgG anti-serotonin and IgG anti-dopamine. There was a trend for the amount of IgM anti-dopamine to be lower in patients than in controls. Dopamine and serotonin are specific components of brain cells. It can therefore be hypothesized that these antigens acting with autoantibodies could be the antigenic cerebral targets reacting with 'anti-brain' antibodies. The study of these specific autoantibodies provides information about the immunological characteristics that may be related to brain disturbances.

[Bulimia and autoimmunity]

In the first part of this study, we investigated the rate of natural autoantibodies, in a sample of 31 female inpatients with bulimia nervosa according to DSM III-R criteria. The control (age and sex matched) group consisted in high school students including 10 females without eating disorders, depressive disorder or immunological disease. We investigated especially natural autoantibodies reacting with compounds of the central nervous system (Dopamine, Dopamine beta Hydroxylase, Serotonin). Our first conclusion is that there is a lower level of these natural auto-antibodies among female patients with bulimia nervosa. In the second part of the study, we have especially investigated the correlation between impulsivity in bulimia nervosa and the rate of natural autoantibodies against serotonin.

A comparative study of defense styles of bulimic, anorexic and normal females

We have compared the defense styles of anorexic (N = 41), bulimic (N = 37) and normal females (N = 72) living in Paris, using the Bond Defense Style Questionnaire relating to 17 defenses: sublimation, anticipation, suppression, undoing, idealization, reaction formation, projection, passive aggression, acting out, isolation, devaluation, autistic fantasy, denial, displacement, dissociation, splitting and somatization. The objective of this study was to better understand the personality structure in terms of psychological defenses of adolescent girls and young women suffering from anorexia or bulimia nervosa (DSM-III-R). Data showed significant differences of psychological functioning between control subjects and eating disorder subjects, particularly for the projection, undoing and sublimation defenses. Anorexics differed from the bulimic females only on the passive aggression, isolation and devaluation defenses. These data are discussed in relation to the hypothesis that anorexics and bulimics can be situated on the same continuum ranging from normal to eating disorders with certain common psychological features as risk factors shared by the eating disorder females.

[Manic-depressive psychoses in adolescence. Influence of life change events. Study of family dynamics]

A sample of 38 adolescents hospitalized for a major depressive episode melancholic type or a manic episode during the course of a bipolar disorder (according to the DSM III-R Criteria) was examined with particular emphasis on precipating life events and family relationships. Psychosocial stressors in the year preceding onset of the affective disorder were found in a very high proportion of cases (about 80%). Stressors are most often severe. All of these stressors have to do with loss or threat of loss, particularly the most frequent one: the sentimental failure. Analyzing results of a familial dynamic questionnaire, we showed in the MDD sample the prevalence of two psychopathological index: maternal rejection, parental dysharmony.

[Pharmacologic treatment of bulimia]

The rationale for pharmacological treatment of bulimia nervosa is summarized and a review of controlled therapeutic trials shows contradictory results. A number of antidepressant agents (tricyclics: imipramine, desipramine, amitriptyline; IMAO: phenelzine, isocarboxazide; trazodone; fluoxetine) appear more effective than placebo in double-blind controlled trials of 6 to 16 weeks. In similar studies, other antidepressants (mianserine, fluvoxamine) are ineffective. Improvement reported is often incomplete and the low percentage of patients totally abstinent at the end of treatment appears of poor pronostic value for long-term outcome. Methodological limitations of existing studies are discussed, and some psychopathological factors to consider in the assessment of therapeutic response are proposed.

Preliminary study of eating disorders among French female adolescents and young adults

We have performed an exploratory study of eating disorders among female adolescents (N = 38) and young adult (N = 38) students living in Paris, France. A high percentage of the subjects in the adolescent (68.4%) and young adult (50%) groups displayed one or more atypical eating behaviors with grazing being prominent (60.5% and 42.1%, respectively) in both groups. Bulimia nervosa (DSM-III-R) was found only in the older group (3/38 vs. 0/38). Binge eating was significantly more frequent among the older subjects (12/38 vs. 1/38). Nicotine dependence and daily grazing with a history of grazing during childhood were reported in all subjects with bulimia nervosa (DSM-III-R). These data, while requiring replication in larger samples, indicate that atypical eating behaviors are common in the populations sampled. Furthermore, daily grazing (especially with a history of grazing during childhood) and nicotine dependence may be strongly associated with the development of bulimia nervosa.
