Mood disorders in eating disorder patients: Prevalence and chronology of ONSET.

OBJECTIVES: In a clinical population, we estimated the frequency of mood disorders among 271 patients suffering from Anorexia Nervosa (AN) and Bulimia Nervosa (BN) in comparison to a control group matched for age and gender. METHOD: The frequency of mood disorders was measured using the Mini International Neuropsychiatric Interview (MINI), DSM-IV version. RESULTS: Mood disorders were more frequent among eating disorder (ED) patients than among controls, with a global prevalence of the order of 80% for each ED group. The majority of the mood disorders comorbid with ED were depressive disorders (MDD and dysthymia). The relative chronology of onset of these disorders was equivocal, because mood disorders in some cases preceded and in others followed the onset of the eating disorders. LIMITATIONS: Our sample was characterized by patients with severe ED and high comorbidities, and thus do not represent the entire population of AN or BN. This also may have resulted in an overestimation of prevalence. CONCLUSION: Mood disorders appear significantly more frequently in patients seeking care for ED than in controls. These results have implications for the assessment and treatment of ED patients, and for the aetio-pathogenesis of these disorders.

[Pathological gambling in adolescence]. / Le jeu pathologique à l'adolescence.

Today's juveniles are the first generation to be raised in an environment where gambling is very accessible and socially acceptable. The recent legalization of Internet gambling has increased this accessibility. With 28,8 millions of gamblers in France in 2010, many believe that gambling is an innocent leisure activity. The first results of the national survey on the prevalence of gambling practices conducted in France show that in 2010, 1.3% of the population had a gambling problem. Also, despite the prohibition of gambling to minors, the mean age of onset of gambling behavior in the world is 11.5 years. Gambling (even non-problematic) in adolescence is associated with poor school performance, criminal behavior and family conflict. Recreational gambling shares with pathological gambling high rates of psychiatric comorbidities in adults, and risk behaviors among adolescents. Similarly, international studies show prevalence of problem gambling 2 to 4 times higher among adolescents than among adult, 3.5% to 8% of adolescents between 12 and 17 are pathological gamblers. The validity of the screening instruments and the frequency of spontaneous recovery in adulthood are discussed to explain the high prevalence in adolescence. This article proposes a focus on the practice of gambling in adolescence and its characteristics when the practice becomes pathological. We discuss the epidemiological, diagnostic, etiologic and therapeutic aspects of this problem. Three major types of risk factors implicated in gambling problems are identified: some of them are related to the subject (individual factors), others are related to the object of the addiction, here the gambling activity by itself (structural factors) like Internet with the recent legalization of gambling online, and the last are related to environment (contextual or situational factors). Thus, the development and maintenance of pathological gambling in youth seems to be conditioned by the interaction of a person and a gambling activity, in a particular context. This conceptual model is based on the well-known theory of Olivenstein on toxicomania, which was proposed in the seventies. In France, very few is known about problem gambling in this age and its implications in terms of treatment, prevention and research. There is little in the way of specific treatments for adolescent pathological gamblers so we briefly reviewed possibilities and limits. We discuss the importance to develop prevention, in particular to delay the initiation, and the necessity of research to develop screening instruments and news studies to have a better knowledge of this population.

[Description of medicosocial profiles of pharmacodependent subjects consulting addictology centres using a computerized database]. / Description de profils médicosociaux de sujets pharmacodépendants consultant en addictologie à partir d'une base de données informatique.

INTRODUCTION: Lots of similar vulnerabilities to substance use disorders are described in the literature: clinical, genetics, family, environment, etc. Although, when we follow up patients, we know perfectly well that there are also differences due to the substance mainly causing addiction. But we found very little research on the differences between various substance use disorders according to the substance mainly causing dependence. HYPOTHESIS: Our main hypothesis was that significant differences do not exist in medical and social data between patients with substance use disorders according to the substance mainly used. We expected to find significant differences between illegal substance use disorders (opiates, cocaine, cannabis) and legal substance use disorders (BZD, alcohol). OBJECTIVE: Our study aimed to identify differences between patients with substance related disorders in medical and social data according to the main addictive substance. MATERIAL AND METHOD: A specific software has been created by the CEIP and the Department of Addictology of Nantes University Hospital. Anonymous data were gathered and all patients gave their written consent. This database has been declared to CNIL (number 1350706). All data have been directly collected by the physician during medical consultation. The following data were recorded during the first medical examination: age, sex, illicit substance use, prior criminal record or psychiatric disorders, prior addictive behaviours among relatives and/or friends, family history (divorce, separation, abandonment). Other data were gathered prospectively: socioprofessional insertion, marital status, drug prescriptions (time and duration). RESULTS: We found significant differences in social (age, sex) and medical data (prior psychiatric disorders) between patients according to the substance causing dependence. We identified five profiles depending on the substance: cannabis, cocaine, heroin, alcohol and benzodiazepine. DISCUSSION: We clearly identified different types of patient's profiles according to substances mainly causing addiction. These differences can modify our strategies of prevention and treatment, so as to meet patients' needs better.

[Pathological gambling: risk factors]. / Jeu pathologique : facteurs impliqués.

CONTEXT AND OBJECTIVE: In France, consumption of gambling games increased by 148% between 1960 and 2005. In 2004, gamblers lost approximately 0.9% of household income, compared to 0.4% in 1960. This represents approximately 134 Euros per year and per head. In spite of this important increase, the level remains lower than the European average (1%). However, gambling practices may continue to escalate in France in the next few years, particularly with the recent announce of the legalisation of online games and sports betting. With the spread of legalised gambling, pathological gambling rates may increase in France in the next years, in response to more widely available and more attractive gambling opportunities. In this context, there is a need for better understanding of the risk factors that are implicated in the development and maintenance of pathological gambling. METHODS: This paper briefly describes the major risk factors for pathological gambling by examining the recent published literature available during the first quarter of 2008. This documentary basis was collected by Inserm for the collective expert report procedure on Gambling (contexts and addictions). Seventy-two articles focusing on risk factors for pathological gambling were considered in this review. Only 47 of them were taken into account for analysis. The selection of these 47 publications was based on the guide on literature analysis established by the French National Agency for Accreditation and Assessment in Health (ANAES, 2000). Some publications from more recent literature have also been added, mostly about Internet gambling. RESULTS: We identify three major types of risk factors implicated in gambling problems: some of them are related to the subject (individual factors), others are related to the object of the addiction, here the gambling activity by itself (structural factors), and the last are related to environment (contextual or situational factors). Thus, the development and maintenance of pathological gambling seems to be conditioned by the interaction of a person and a gambling activity, in a particular context. This conceptual model is based on the well-known theory of Olivenstein on toxicomania, which was proposed in the seventies. The structural factors that appeared to be highly related to pathological gambling development and maintenance are payment modality, entertaining dimension, temporality, reward level, educational messages, gambling ambiance, gambling medium and part of hazard. Among contextual factors, availability and accessibility of gambling opportunities are well known. However, social and economic factors (e.g. culture, ethnicity, religion, education) are also important. Lastly, among individual factors, psychosocial factors are gender, age, familial and personal antecedents and psychiatric comorbidities. Neurobiological factors are not discussed here. CONCLUSIONS: This paper briefly summarises risk factors for development and maintenance of pathological gambling. It highlights that these factors are very similar to those that are implicated in substance use disorders, except for the gambling activity and context. Prevention regarding behavioural addictions should, in the future, take advantage of the findings on substance use disorder, since behavioural addictions are less known. Conversely, it seems obvious that findings on pathological gambling, and more widely behavioural addictions, could highlight all types of addiction. It appears that this fact is especially valid with regards to the evolution and stability of addictive status, which must be taken into account for treatment proposals.

[Epidemiological study on addictive behaviours during pregnancy in a universitary department]. / Étude de prévalence des conduites addictives chez les femmes enceintes dans une maternité universitaire.

OBJECT: Epidemiological study on addictive disorders during pregnancy. METHODS: An epidemiological study about addictive disorders has been led in the maternity of the University Hospital of Nantes in 2008 on a sample of 300 women, just after childbirth. The prevalence of consumption of drugs was assessed on declared consumption of legal and illegal substances and on the Fagerström questionnaire, the AUDIT questionnaire and the CAST questionnaire. Diagnostic of eating disorders was based on DSM IV criteria of mental anorexia and bulimia nervosa. RESULTS: At the beginning of pregnancy, 34% of women used tobacco, 63% alcohol and 8% cannabis. Among the women of the study 0.7% had criteria for mental anorexia, 2.3% for bulimia nervosa and 9% for sub clinic forms. After the first trimester, 22% of women declared using tobacco, 20% alcohol and 3% cannabis. The use of various drugs during pregnancy concerned 6.3% of women, and 38% used at least one drug after the first trimester. CONCLUSION: The high prevalence of addictive disorders during pregnancy should incite professional of prenatal care to improve their screening methodology and not only when tobacco or alcohol is suspected.

[Socio-demographic and clinical assessment, and trajectory of a sample of French pathological gamblers]. / Évaluation sociodémographique, clinique et du parcours de jeu d'un échantillon de joueurs pathologiques français.

INTRODUCTION: International studies estimate the incidence of pathological gambling among adults at 0.2-3%. Following the lead of Anglo-Saxon countries, France has only just begun to consider this "new" addiction in studying its own population of pathological gamblers, attempting to understand the causes of the illness, and proposing specific treatments. OBJECTIVE: The purpose of this study was to carry out a multiaxial assessment of French pathological gamblers, current or former outpatients of the addiction ambulatory care center of the University Hospital of Nantes, in order to compare our findings with those of the international literature. METHOD: During a single personal interview, the participants filled in a set of questionnaires including a description of gambling characteristics (pathological gambling section in the DSM-IV, South Oaks Gambling Screen, gambling history), a screening for axis I (Mini International Neuropsychiatric Interview) and II (structured clinical interview for DSM-IV Axis II Personality Disorders), comorbidities and personality tests using a dimensional approach (Minnesota Multiphasic Personality Inventory, Sensation Seeking Scale, Barratt Impulsiveness Scale, Toronto Alexithymia Scale). The number of subjects to include was not previously calculated, since the size of the sample depended upon each subject's availability and on the inclusion time period limited to 4 months. Continuous variables were described in terms of means and standard deviations, while categorical variables were described in terms of percentages. The protocol was accepted by the Advisory Committee for the Protection of Biomedical Research Subjects. RESULTS: Analysis of the findings was based on a sample of 24 subjects. Half of the subjects fell into severe pathological gambling. Gambling had started at an average age of 24.9 years (S.D.=12.3). The gambling problem appeared on average 9.4 years later (S.D.=8.1). Casinos (41.7%) and sports pools (45.8%) were the most commonly reported types of games. Seventy-five percent of the sample suffered from at least one axis I psychiatric comorbidity. Most common among these were current (20.9%) and past (37.5%) episodes of major depression. Risk of suicide was observed in 36% of subjects, and nearly half of them were not currently suffering from an episode of major depression. The second most common psychiatric comorbidity was substance abuse (including alcohol) (54.2%). Personality disorders were common (54.2%) and mainly cluster B disorders (29.2%). Impulsiveness and alexithymia scores were above average, unlike sensation seeking scores. CONCLUSIONS: The results go along the same lines as those mentioned in the international literature and show how important it is to carry out multidimensional assessments within the context of pathological gambling, since comorbidities are such a burden. This study brings to light several perspectives. It would be interesting to repeat the assessment using a much larger sample. We plan to study those factors that influence the emergence of pathological gambling, and the initiation of specific treatments for pathological gamblers. Upon completion, the study would allow us to propose the treatment that is best suited to each gambler's profile.

[Are anxiety or depressive disorders more frequent among one of the anorexia or bulimia nervosa subtype?]. / La fréquence des troubles anxio-dépressifs diffère-t-elle entre les types diagnostiques d'anorexie mentale et de boulimie?

UNLABELLED: Our objective was to answer the following question: are there differences between diagnostic groups of eating disorders (ED) for the prevalence of depressive and anxiety disorders, when clinical differences between the groups are taken into account (ie age of subjects, ED duration, inpatient or outpatient status, and Body Mass Index)? METHOD: We evaluated the frequency of anxiety disorders and 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. We compared the prevalences between sub-groups of anorexics (AN-R and AN-BN), between sub-groups of bulimics (BN-P and BN-NP) and between anorexics and bulimics while adjusting for the variables defined below. RESULTS: Current or lifetime comorbidity of anxiety and depressive disorders did not differ between AN-Rs and AN-BNs, nor between BN-Ps and BN-NPs. Only current diagnoses of agoraphobia and obsessive-compulsive disorder were significantly more frequent in anorexics than in bulimics. CONCLUSION: The greater frequency of comorbidity between obsessive-compulsive disorder and AN compared to BN, already well documented, is not questioned. The remaining anxiety disorders are equally frequent among all the diagnostic types of ED.

[Is depressive disorder linked to anxiety disorder among anorexics and bulimics?]. / L'existence d'un épisode dépressif majeur est-elle liée à la présence de troubles anxieux chez les anorexiques et les boulimiques?

UNLABELLED: 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.

[Alexithymia, depression and drug addiction]. / Alexithymie et toxicomanie:

Alexithymia is a multidimensional concept associating an emotional component focused on the difficulty in identifying and describing feelings and a cognitive one centred on the use of a concrete and poorly introspective way of thinking. Alexithymia can be assessed by self-assessment instruments and in particular by the 20 items version of the Toronto Alexithymia Scale (TAS-20). Depressive disorders have complex relationships with the construct of alexithymia and there exist few experimental works on the subject. Epidemiological studies frequently raise an overlap between alexithymia and depression, in particular in the context of addiction. The main aim of this study was to confirm the high prevalence of alexithymia among drug addicted patients taking into account socio-demographic variables (sex, age, social and economic categories). The second aim of the study was to investigate the relationships between alexithymia and depression among drug addicted patients. A sample of 128 drug addicted patients answering DSM IV criteria of dependence to a psycho-active substance (alcohol excluded) was paired according to socio-demographic variables to a control sample of 128 normal subjects. Diagnostic assessment was made using the Mini International Neuropsychiatric Interview (MINI). Alexithymia and depression were assessed with the TAS-20 and with the short version of the Beck Depression Inventory (BDI-13). The results confirm the high prevalence of alexithymia among drug addicted patients (43.5%) compared to controls (24.6%). This difference is based namely on the emotional component of alexithymia, the cognitive component failing to show any difference between the two samples. Moreover, alexithymia appears to be independent from socio-demographic variables in our sample of drug addicted patients; 66.4% of drug addicted patients presents a depressive symptomatology (which is significantly more important in female patients), compared to 26% of the controls. Studies using the TAS and the BDI with 21 items have shown that from 10 to 20% of the variance of alexithymia is explained by depression. Our own results show a shared variance of 20% between the TAS-20 and the BDI, going in the direction of a moderated correlation between alexithymia and depressive symptomatology. Moreover, when we retain only subjects without depressive symptomatology at BDI, drug addicted (n=42) are not any more alexithymic than controls (n=114). Our results plead for a positive association between depression and alexithymia in drug addicted, depressed or healthy subjects. Alexithymia and depression would be two associated dimensions, the emotional component explaining alone this association. The emotional component of the alexithymia would be thymo-dependent, whereas the cognitive component (externally oriented thought) would be independent and constitute a stable clinical feature. These results are concordant with other studies in the literature suggesting that alexithymia in its emotional component is supported by depression. Alexithymia thus did not appear as an autonomous dimension which would discriminate between drug addicted and controls, independently of the absence of a depressive state. The Authors discuss the complexity of the relationships between alexithymia and depression and the correlations between TAS and BDI scales especially for the factor Difficulty Identifying Feelings. These results deserve further studies. The cross-sectional nature of this study do not allow to establish if alexithymia is a subjacent and preexistent in the form of a psychopathological dimension in addictive behaviours, so supporting its emergence, and/or if it develops once the dependence is installed and chronicized. Longitudinal studies remain to be realised.

Predictive factors of social disability in anorexic and bulimic patients.

OBJECTIVES: The purpose of this study was to determine whether subjects suffering from anorexia nervosa (AN) or bulimia nervosa (BN) would demonstrate more severe social disability than a control group; and whether social disability could be best explained as a function of the eating disorder itself or as a function of comorbid anxiety or depressive disorders. METHOD: Subjects were 166 AN subjects, 105 BN subjects and 271 control subjects matched for age, sex and socio-economic status. Prevalence of anxiety or depressive disorders was assessed (through the Mini International Neuropsychiatric Interview), and social functioning was measured (through the Groningen scale). RESULTS: The majority of AN and BN subjects demonstrated social disability in the "social role" (leisure time, time spent with friends) and the "occupational role" (work or educational activities). A regression analysis was employed to uncover predictive factors of social disability. Eating disorders (AN and BN), anxiety disorders and depression accounted for a large portion of social disability. DISCUSSION: Anxiety and depressive disorders appear to play an important role in the type of social disability demonstrated in eating disorder patients. Therapeutic implications are discussed.

[Validation study of the Depressive Experience Questionnaire]. / Etude de validation du Depressive Experience Questionnaire.

Sidney Blatt, considering as being insufficient the categorical-symptomatic approach of depression, has worked out a theory of depression and psychopathology that integrates the contributions of psychoanalysis as well as cognitive and developmental psychology. Within a broad psychoanalytic framework, Blatt's formulation focus on the quality of interpersonal relationship, the nature of object representation and early life experiences. Personality development is viewed as the consequence of the interaction of 2 basic developmental tasks: the establishment of the capacity to form stable, enduring, mutually satisfying interpersonal relationships and the achievement of a differentiated, realistic, essentially positive identity. The relationship between these 2 developmental lines involves a complex dialectical process during which progress in each line is essential for progress in the other and which contributes to the development of both a sense of identity and the capacity for interpersonal relatedness. These developmental lines permit not only to define an during individual's primary personality configuration but also enable to identify cognitive structures that are inherent in various forms of psychopathology, including depression. Disruptions at different developmental stages create vulnerability to different subsequent psychological disturbances. Blatt characterised as anaclitic or dependent the axis concerned with interpersonal relationship and as introjective or self-critical the axis concerned with development of the sense of self and identity. Depressive Experience Questionnaire was developed by Blatt et al. to determine the validity of this model of psychopathology which emphazises continuities between normal and pathological forms of depression. The instrument was developed by Blatt et al. by assembling a pool of items describing experiences frequently reported by depressed individual. Sixty-six items were selected and administered to a large nonclinical sample (500 female and 160 male undergraduates). Principal component analysis within sex performed on the answers to DEQ confirmed his assumption in identifying two principal depressive dimensions. The first factor involved items that are primarily externally directed and refer to a disturbance of interpersonal relationships (anaclitism); the second factor consists of items that are more internally directed and reflect concerns about self-identity (self-criticism). A third factor emerged, assessing the good functioning of subject and confidence in his resources and capacities (efficacy). Scales derived from these factors have high internal consistency and substantial test-retest reliability. The solutions for men and women were highly congruent. Factor structure has been replicated in several nonclinical and clinical samples, supporting considerable evidence to the construct validity of the DEQ Dependency and Self-criticism scales. An adolescent form of DEQ (DEQ-A) has successively been developed. Factor analysis revealed three factors that were highly congruent in female and male students and with the three factors of the original DEQ. The reliability, internal consistency and validity of DEQ-A indicate that the DEQ-A closely parallels the DEQ, especially in the articulation of Dependency and Self-criticism as two factors in depression. These formulations and clinical observations about the importance of differentiating a depression focused on issues of self-criticism from issues of dependency are consistent with the formulations of others theorists which, from very different theoretical perspectives, posit 2 types of depression, one in which either perceived loss or rejection in social relationships is central and the other in which perceived failure in achievement, guilt or lack of control serves as the precipitant of depression. These 2 types of experiences have been characterized as dominant other and dominant goal , as anxiously attached and compulsively self-reliant and as sociotropic and autonomous . Our work presents the results of a validation study of both forms of Blatt's questionnaire (for adults--DEQ--and for adolescents--DEQA) translated in French in a large population of normal subjects, aged 15 to 45 years. DEQ and DEQ-A were compared by inspection of items loading strongly on each factor and by correlation of the three factors of adults and adolescents. The exploratory factor analysis of DEQ and DEQA revealed three orthogonal factors, corresponding with Blatt's original dimensions. Consistency and external validity were adequate for all 3 factors of DEQ and DEQ-A. Anaclitism and self-criticism dimensions of DEQ and DEQ-A correlate positively with measures of depression (DSM-IV, Beck Depression Inventory), consistently with the results obtained by Blatt. Differently from this author, anaclitism appears to be less differentiated in males than in females, suggesting that the concept of dependence could assume different relevance for men and women.

[Psychoactive drug use in a declared non-addicted control sample and comorbidity. Results of a study in 860 French-speaking subjects]. / Consommation de substances psycho-actives dans une population témoin déclarée non addictive et co-morbidité. Résultats d'une étude chez 860 sujets francophones.

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.

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 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.

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.

[Pertinence of the addiction concept in eating behavior disorders]. / Pertinence du concept d'addiction dans les troubles des conduites alimentaires.

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.

Follow-up of bone mineral density in 27 cases of anorexia nervosa.

Cortical and trabecular bone loss can lead to osteoporosis in chronic forms of anorexia nervosa (AN). As there is some debate about the reversibility of this condition, we performed a longitudinal follow-up study of 27 cases in which clinical, biological, X-ray and lumbar and femoral neck dual photon absorptiometry examinations were conducted every 6 months for up to 30 months. Three groups were distinguished: G1, untreated amenorrheic AN (N = 14, total follow-up 126 months); G2, effectively treated AN (N = 11, total follow-up 192 months), with two subgroups: fluoride (N = 5) and estrogen (N = 6); and G3, remitting AN with normalization of the gonadic function (N = 2, total follow-up 36 months). Results were adjusted for each patient to a 6-month variation. Semestrial variations in lumbar bone mineral density (BMD) were -2.1 +/- 1.3%, +2.8 +/- 1.5%, and -0.3 +/- 1.3% (mean +/- SEM), respectively for G1, G2 and G3; those for femoral neck BMD semestrial variations were -5.9 +/- 2.1%, -3.8 +/- 1.2% and -1.0 +/- 0.6%. Femoral neck and lumbar BMD variations for G1 were mainly correlated positively with bone-forming markers (serum osteocalcin, alkaline phosphatase) and negatively with initial lumbar BMD. Estrogen alone increased lumbar BMD by +1.4 +/- 2.3% every 6 months but did not stabilize femoral neck BMD (-3.5 +/- 1.4%). Fluoride increased lumbar BMD by 4.8 +/- 1.8%. Both lumbar and femoral neck BMD were stabilized in the remission group (-0.3 +/- 1.3% and -1.0 +/- 0.6%), despite half of the follow-up time with amenorrhea. In conclusion, untreated AN is associated with a marked trabecular and cortical bone loss (4-10% per year), which can lead to osteoporotic fractures. In prevention of bone loss, the efficacy of estrogen is difficult to investigate in AN, even with a well-controlled trial. Our study could provide argument that, when the observance of this preventive treatment is assessed, lumbar BMD can be stabilized in chronic forms of AN.
