Déficit émotionnel et intelligence machiavélique : étude des interrelations entre l'échelle d'alexithymie de Toronto (TAS-20) et l'inventaire mach-iv dans une population de 201 étudiants

The aim of the study was to explore the relationship between alexithymia and machiavellianism in a group of 201 university students. The subjects filled out the TAS-20 and the MACH-IV forms. The results showed firstly, a significant correlation between the two total scores (r = 0.35, P < 0.05), and secondly between the identification of feelings subscale of the TAS-20 and the opinions about human nature subscale of the Mach-IV (r = 0.44, P < 0.05). The results were discussed in light of the different factors (depression, dependency, psychoticism…) that could explain the relationship between the two concepts.     

Gefühl ohne Sprache oder Sprache ohne Gefühl? Weitere Hinweise auf die Validität der Entkopplungshypothese der Alexithymie

The theoretical background of the present investigation was the decoupling hypothesis of alexithymia, which presumes for alexithymic individuals a dissociation of psychophysiological indicators of emotion from verbal cognitive awareness of one's emotional state. To study alterations in reactivity to emotionally distressing stimuli in alexithymic individuals, 12 high-alexithymic and 14 low-alexithymic subjects (separated by TAS) out of a general sample of 54 were investigated. All subjects were exposed to cognitive (CPT) and affect inductive (film sequences) distress. During stimulus exposition electrodermal activity (spontaneous fluctuations) was recorded. After stimulus exposition the subjects assessed their emotional reaction towards the film sequences (DAS). Concerning electrodermal activity no differences were found between high and low alexithymics under cognitive distress. In any case a significant autonomous arousal was registered. However, only the low alexithymic subjects but not the high alexithymics showed a significant increase of spontaneous fluctuations as expression of autonomous arousal during presentation of affect inductive stimuli. The altered psychophysiological reactivity found in high alexithymics in contrast to low alexithymic subjects was revealed specifically for the processing of emotional qualified stimuli. However, there was no difference between the groups in cognitive self assessment of emotional response towards the film sequences. The findings are discussed with reference to neurophysiological and psychodynamic models and the decoupling hypothesis of alexithymia.     

Joueurs de machines à sous dans une population française : étude de la dépression, de l’alexithymie et de la recherche de sensations

There are a multitude of factors implied in the acquisition, the development and the maintenance of gambling behavior. Among them, sensation seeking occupies an important place. Zuckerman originally suggested a relationship between sensation seeking and gambling. However, studies in this area have provided heterogeneous results. To explain these discrepancies, Zuckerman emphasized the fact that the type of gambling may be a crucial factor in the relationship with sensation seeking. Nevertheless, few studies have evaluated the link between the different types of gambling and problem behaviors. Furthermore, few studies were interested specifically on slot machines. While recent research has found high-levels of alexithymia in individuals with substance use and eating disorders only two studies have investigated the relationship between alexithymia and pathological gambling. Thus, these studies were focused on students. It is therefore important to study alexithymia in adult gamblers. Empirical data has shown that alexithymia levels may be influenced by negative mood states, especially depression. Some studies have found a positive correlation between alexithymia and depression scores, particularly in people with addictive behaviours. Nevertheless, studies found heterogeneous results. The main objective of this research was to evaluate scores on sensation seeking, alexithymia and depression (and the link between those variables) in gamblers of slot machines. Thus, slot machines gamblers were selected in the casino of Enghien-les-Bains, which is Paris nearest casino. Among them one distinguishes: regular gamblers (n = 45) from which were extracted pathological gamblers (n = 27), and occasional gamblers (n = 19). The South Oaks Gambling Screen and the criteria of the DSM-IV were used to measure the intensity of gambling behavior; sensation seeking was evaluated by the Sensation Seeking Scale form V; alexithymia by the Toronto Alexithymia Scale (TAS-20) and the depression by the Beck Depression Inventory. No differences appeared significant between the three groups of gamblers for the sensation seeking scores. Pathological gamblers obtained higher alexithymia scores than occasional gamblers. Nevertheless, these findings didn’t remain stable when controlling for the effect of depression. Among pathological gamblers, the BDI score is positively correlated to the ‘difficulty identifying feelings’ factor. This result is consistent with the literature, which shows that alexithymia is closely related to depression in addictive behaviors. Indeed, the ‘difficulty identifying feelings’ factor seems to be explained by depression severity. These results suggest that the emotional component of alexithymia would be thymo-dependent, whereas the cognitive component would be independent and constitute a stable clinical feature. Pathological gamblers who play slot machine are low sensation seekers who shun the more dramatic and extraverted form of sensation seeking. They play to reduce or avoid unpleasant emotional states like depression. Pathological gambling could therefore be in part a maladaptive coping strategy to deal with affective disturbances; the game may function as a self-medication to treat emotional states, which the gambler finds no other way of treating. According to previous studies, slot machine gambling is referred to as ‘escape’ gambling, where gamblers may dissociate.     

La recherche psychosomatique en 2018 : illusions perdues,espoirs renouvelés

A critical analysis of the basic hypotheses of psychosomatic research and the sometimes hasty assertions drawn from the previous works makes it possible to better discern the data confirmed by the most recent works or the most rigorous meta-analyses and to highlight the emerging tracks. If the hypothesis of behavioral patterns specifically related to the risk of certain pathologies seems abandoned, the predictive value of depression in the cardiovascular field, more than in that of oncology, becomes clearer. Negative affect and impaired emotional awareness emerge as two complementary factors of somatic vulnerability. Several vulnerability factors seem all the more effective as they affect individuals of lower socio-economic status. Social exclusion feeling and its links with the inflammatory response appear to be a possible common denominator, both for depression and for many somatic conditions. A series of studies on the cerebral regulation of emotions and stress, as well as on bidirectional brain-bowel relations and on the mediating role of the gut microbiota, complements the available epidemiological data. The same is true for certain advances in behavioral neuro-economics, which inform the decision-making processes of patients facing preventive health choices. Lastly, it appears that a significant part of the excess mortality associated with the existence of severe mental disorders is not due to factors inherent to the patients themselves, but to disparities in the quality of the care provided to them.     

La psychiatrie de liaison. Quelle actualité, quelles perspectives ?

The author addresses three key issues concerning the state of art and the future of consultation-liaison psychiatry. In the context of medico-economic constraints, it is important both to be provided with epidemiological arguments on the prevalence of psychiatric comorbidities in medically ill and their impact on health and sanitary costs, and to seize the opportunity to upgrade consultation-liaison psychiatry, especially through correctly coding of discharge summaries, taking into account such comorbidities, given their impact on hospital receipts. Screening for depressive disorder in medicine remains a priority for consultation-liaison psychiatry. Epidemiology has consistently shown the prognostic value of such symptoms, especially in the cardiovascular field. The relationship between depressive symptoms and cognitive hostility deserve to be better taken into account and can guide the type of follow-up. A growing literature has been devoted to the links between alexithymia, emotional awareness, somatic vulnerability. Several examples are given of the operational nature of these concepts, based on experimental studies, and paths are suggested that open to better understand the links between alexithymia and empathic ability of the patient, but also between empathic ability of the caregiver and therapeutic alliance. These concepts, which refer more to medical psychology than to psychiatric nosography, make the richness of the field of consultation-liaison psychiatry.     

How can the Alexithymia and Behavioural Inhibition predict the perceived pain intensity in patients with chronic pain?

ObjectiveThis study investigates the mediating role of behavioral inhibition system in the relationship between alexithymia and perceived pain intensity in patients with chronic pain, and the moderating role of anxiety in the relationship between behavioral inhibition system and the perceived pain intensity in such patients.MethodsThe research was conducted on 440 patients with chronic pain who were referred to pain centers in Tehran. Participants were asked to answer Toronto Alexithymia Scale (TAS-20), The Inhibition/Activation System Scale (BIS/BAS), Numerical Rating Scale (NRS) for perceived pain intensity, and Depression, Anxiety, and Stress Scale (DASS).ResultsThe results indicated that behavioral inhibition system plays a mediating role in the relationship between alexithymia and perceived pain intensity in patients with chronic pain. Anxiety plays a moderating role in the relationship between the behavioral inhibition system and perceived pain intensity, as well.ConclusionThe relationship between alexithymia and the perceived pain intensity is not a simple linear one, but is mediated by behavioral inhibition system. Also, anxiety determines the effect of the behavioral inhibition system on the perceived pain intensity of the patients.     

Validity of the BVAQ: a study in eating disorder patients and controls

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.     

Personnalité et troubles somatiques

In the title of this text, by somatic disorders we mean those physical illnesses clearly related to a non-psychiatric medical field, frequently termed psychosomatic illnesses and somatoform disorders. For forty years, a trend of thought has focused with pertinence on the psychological peculiarities in patients with severe somatic diseases. Moreover, causality was often supposed in the regularly mentioned association between personality features and somatoform disorders. However, the revival of the study of the earlier field of relationships between mind and body by Briquet, Charcot, Janet and Freud in his first period has led to the reassessment of the meaning of these observations. This reexamination is marked out by several assertions. Two of them work as preliminaries to argumentation: 1. existential wounds may produce long-lasting personality alterations; 2. existential wounds may produce somatoform disorders. These phenomena have been rediscovered over the last few years among assaulted subjects as well as war veterans in whom a frequent occurrence of somatizations has been, in addition, closely linked to the incidence of behavior or personality disorders. Two theses then emerge: 1. somatic diseases may produce long-lasting personality alterations; 2. until now no premorbid personality univocally predisposing to somatic diseases could be found. Indeed, during the 1980s a growing body of negative results coming from retrospective and prospective studies as well as anatomical comparisons have accumulated upon the potential role of certain personality factors in the incidence of somatic illnesses. This dialectic leads to the connection of two corollary assertions: 1. “pensée opératoire” and “alexithymia” in patients with somatic diseases may represent only an effect of the announcement or chronicity of the organic disease; 2. the old “dissociative hysteria” with somatic manifestations finds its substratum in existential wounds and not in pre-trauma personality. Indeed, on the one hand, recent publications do not allow the assertion to be confirmed that alexithymia and “pensée opératoire” predispose to somatizations. On the other hand, personality disorders in subjects with “dissociative hysteria” as well as their somatoform symptoms appear mainly as an effect of an existential wound and express in fact the Janetian concept of “a drop in Psychological Tension”. Then, in spite of their differences, conversion and psychosomatic symptoms share the property of being a primitive response to existential wounds in which the subject cannot produce any appropriate psychic or behavioral response to his distress. Light is shed on these phenomena when put alongside the field of “fixed ideas” thought of by Pierre Janet as the recourse to archaic automatisms. Indeed, the experience which contradicts the vision of existence provokes an “unspeakable terror”. It is mentally unrepresented or represented in too slight a way. In such cases, no previous personality prevails, but the resulting personality often appears modified, including when the breakdown of vision of the existence results from the diagnosis of an illness or its protracted course.
