A blended cognitive behavioral intervention for patients with adjustment disorder with anxiety: A randomized controlled trial.

Adjustment disorder with anxiety (ADA) is a common psychiatric pathology worldwide, but it is often undertreated. Cognitive behavioral therapy (CBT) is the first-line treatment, but very few studies have been carried out for the treatment of ADA. Internet-delivered CBT (iCBT) appears to be an effective treatment option, with the potential to reach a larger proportion of individuals suffering from ADA. Guidance is a beneficial feature of iCBT, provided in most studies by email or telephone (traditional guided iCBT). Blended CBT, which combines an online intervention and therapeutic guidance provided in person (face-to-face), could be a way to benefit from both the advantages of face-to-face CBT regarding human interactional quality and the advantages of internet-based CBT in terms of improved access to treatment. In this randomized controlled trial, the effectiveness of two forms of administration of Seren@ctif, a 5-week CBT program for patients with ADA according the DSM-5, was examined: one delivered through face-to-face sessions (face-to-face CBT) and the other delivered online and guided with face-to-face contact with a nurse (blended CBT); these formats were compared with a wait-list control group (WLC). A total of 120 patients were included and randomized to one of these three conditions. Measures were administered before treatment, after treatment and 6 months after inclusion in the study. Both treatment conditions displayed significant decreases in anxiety, depression, worry and perceived stress at posttreatment when compared to the WLC group. The decrease in symptoms was mostly maintained 6 months after inclusion for the two experimental groups. Blended CBT showed significantly greater reductions in anxiety and depression than did face-to-face CBT on some secondary outcome measures. We conclude that both face-to-face CBT and blended CBT are effective treatments for patients with ADA, and we suggest that blended CBT may be slightly more effective than classical face-to-face CBT.

[Elaboration and psychometric properties of a well-being scale at work. The Serenat study among employees in occupational medicine unit]. / Élaboration et qualités psychométriques d'une échelle de bien-être au travail. Étude SERENAT auprès de salariés vus en médecine du travail.

BACKGROUND: Well-being at work is nowadays a major public health challenge. It includes, among others, absence of psychological (anxio-depressive) symptoms, perceived positive work conditions (environment and organization), happiness and good quality of life at work. Many studies have shown that social support and control at work protect mental health while high job demands and effort-reward imbalance are risk factors for anxiety and depression. There is currently no global indicator to measure both the state of mental health and social working conditions. The main objective of this work is to construct and explore the psychometric properties of scale of well-being at work called "Serenat" in order to validate it. METHODS: The Serenat Scale is a self-report questionnaire composed of 20 items. All items are scored on a four-point Likert scale ranging from 0 (strongly disagree) to 3 (strongly agree) resulting in a range of 0 to 60. It was constructed from data collected from the literature and from consultations in an Occupational Health Unit. From January 2014 to May 2017 193 subjects who have consulted an occupational doctor are included in this cross sectional survey. Validation included item quality and data structure diagnosis, internal consistency, intraobserver reliability evaluation and external consistency. RESULTS: The Serenat scale showed very good item quality, with a maximal non-response rate of 0.01 % per item, and no floor effect. Factor analysis concluded that the scale can be considered unidimensional. Cronbach's alpha of internal consistency was 0.89. The intraclass correlation coefficient for intraobserver reliability was 0.89. Serenat scale was correlated with HADS (r=-0.54; P<0.001), STAI-Y (r=-0.78; P<0.001) and BDI-13 (r=-0.57; P<0.001). CONCLUSION: Serenat's well-being at work scale shows good psychometric properties for final validation. It could be useful to occupational physicians for individual and collective screening.

[Interest of computer-based cognitive behavioral stress management. Feasability of the Seren@ctif program]. / Intérêt d'un programme self help de gestion du stress sur support numérique. Étude de faisabilité du programme Seren@ctif.

INTRODUCTION: Cognitive-behavioural stress management programs have been studied in many countries. Many reports have shown beyond a doubt their efficacy to reduce perceived stress, anxiety symptoms and to improve quality of life of patients. Considering the very large number of people who could benefit from such programs but are unable to reach them, self-help programs have been offered. First presented as books (bibliotherapy), these programs then became enriched by computing and digital supports. Regrettably, many of the programs of stress management based on the Cognitive behavioural therapy (CBT) both in face-to-face and on digital support have been little evaluated in France. To our knowledge, the Seren@ctif program is the first French language self-help program of stress management proposed on digital support. AIM OF THE STUDY: We led a feasibility study of this program on 10 patients responding to the diagnosis of adjustment disorder with anxiety according to the DSM IV criteria. METHODS: The program includes 5 weekly sessions that the patient follows in our unit from a web site. He benefits from minimal contact with a medical member of staff before and after every session. Right from the first session an USB key is supplied to the patient containing videos, audio files, self-help book portfolio in the form of an e-guide, and log books with the exercises to be realized between each sessions of the 5 session program. The patient is encouraged to practice 20 minutes of exercises 5 or 6 days per week. The program's feasibility has been assessed in accordance with a standard satisfaction scale. Anxiety symptomatology has been quantified thanks to the Spielberger State-Trait Anxiety Inventory (STAI-Y-S). RESULTS: After the scheduled 5 weeks, good results were found in terms of acceptability and attractiveness. The average score to the satisfaction survey was at least equal to 4 out of 5 for each item. The mean score on the STAI-State decreased from 53,4 (SD: 8,29) to 44,2 (SD: 7,73) following the intervention. DISCUSSION: The Seren@ctif program may be useful within the framework of a psychoeducative approach. It could also be advised for people suffering from anxiety related to stress. Soon, the program will be tested on patients with usual care suffering from adjustment disorder with anxiety in order to precisely assess its benefits.

[An integrative and transdiagnostic relaxation protocol for anxious patients. Results of a pilot study]. / Protocole de relaxation intégrative et transdiagnostique pour patients anxieux. Résultats d'une étude pilote.

INTRODUCTION: The literature data show that relaxation practice is effective in reducing anxiety symptoms. Different techniques such as progressive muscular relaxation, autogenic training, applied relaxation and meditation have been evaluated independently for anxiety disorders. The question is to know whether the combination of various techniques may be of interest in the transdiagnostic treatment of anxiety disorders. AIM OF THE STUDY: The present study assessed the short-term efficacy of a 10-week integrative and transdiagnostic relaxation program for anxiety disorders in outpatients of an anxiety disorders unit. METHODS: The diagnoses were made according to the Mini-International Neuropsychiatric Interview (MINI; Sheehan et al., 1998) and completed with an assessment of anxiety and depressive symptoms using: the State Trait Anxiety Inventory (STAI-Y, -S and -T), the Penn State Worry Questionnaire (PSWQ) and the Beck Depression Inventory (BDI-II). Four techniques were integrated into the structured 10-week protocol: breathing control, muscular relaxation, meditation and mental visualization. RESULTS: Twenty-eight patients (12 men and 16 women), mean age (S.D.)=38.82 years (11.57), were included in the study. All the included patients fulfilled the DSM-IV criteria for a current diagnosis of Generalized Anxiety Disorder (n=13) or Panic Disorder (n=15) with or without agoraphobia. At the end of the 10 sessions, we found a significant reduction in mean scores (S.D.) on the STAI-T from 53.179 (6.037) to 49.821 (8.028) (P<0.02), the BDI-II 20.964 (13.167) to 15.429 (11.341) (d=0.6543) and the QIPS 55.071 (10.677) to 49.679 (11.7) (d=0.5938). The observed reduction in the STAI-S (d=0.2776) was not significant. DISCUSSION: The results of this open study showed that this program significantly decreases the level of trait anxiety, depression and worry. The integrative and transdiagnostic relaxation program could represent an accessible and effective treatment to reduce anxious and depressive symptoms in various anxiety disorders. Future research should address the development of controlled trials assessing the impact of the different dimensions of anxiety and the long-term effects of this protocol.

[Adjustment disorders with anxiety. Clinical and psychometric characteristics in patients consulting a general practitioner]. / Le trouble de l'adaptation avec anxiété. Caractéristiques cliniques et psychométriques chez des patients consultant en médecine générale.

BACKGROUND: The DSM-IV and ICD-10 descriptions of adjustment disorders are broadly similar. Their main features are the following: the symptoms arise in response to a stressful event; the onset of symptoms is within 3 months (DSM-IV) or 1 month (ICD-10) of exposure to the stressor; the symptoms must be clinically significant, in that they are distressing and in excess of what would be expected by exposure to the stressor and/or there is significant impairment in social or occupational functioning (the latter is mandatory in ICD-10); the symptoms are not due to another axis I disorder (or bereavement in DSM-IV); the symptoms resolve within 6 months, once the stressor or its consequences are removed. Adjustment disorders are divided into subgroups based on the dominant symptoms of anxiety, depression or behaviour. Adjustment disorder with anxiety (ADA) is a very common diagnosis in primary care, liaison and general psychiatry services but we still lack data about its specificity as a clinical entity. Current classifications fail to provide guidance on distinguishing these disorders from normal adaptive reactions to stress. METHOD: Ninety-seven patients with ADA according DSM-IV were recruited in this primary care study and compared with 30 control subjects matched for age and sex. The diagnosis was made according to the MINI questionnaire completed with a standardized research of stressful events and an assessment of anxiety symptoms using different scales: the Hamilton Anxiety rating Scale (HAM-A), the Hospital Anxiety and Depression scale (HAD), The Penn-State Worry Questionnaire (PSWQ), the Positive and Negative Emotionality scale, 31 items (EPN-31 scale) and the State-Trait Anxiety Inventory (STAI-S). RESULTS: Life events in relation to work were the most frequent (43%). In terms of symptomatology, results showed that ADA is associated with a level of anxiety close to those obtained in other anxiety disorders, particularly GAD, in relation to general symptoms (physical and somatic) as well as anxious rumination and negative emotions. CONCLUSION: Further research is needed to better understand the disorder and clarify its frontiers, which still remain a controversial issue with regard to the homeostatic response to stress and other types of anxiety disorders. The results of our study suggest that this sub syndromic entity should be recognized and adequately treated, especially in general practice where it is very common.

[Heart rate variability. Applications in psychiatry]. / La variabilité de la fréquence cardiaque. Intérêts en psychiatrie.

BACKGROUND: The autonomic nervous system sends messages through the sympathetic and parasympathetic nervous system. The sympathetic nervous system innervates the cardioaccelerating center of the heart, the lungs (increased ventilatory rhythm and dilatation of the bronchi) and the non-striated muscles (artery contraction). It releases adrenaline and noradrenaline. As opposed to the sympathetic nervous system, it innervates the cardiomoderator center of the heart, the lungs (slower ventilatory rhythm and contraction of the bronchi) and the non-striated muscles (artery dilatation). It uses acetylcholine (ACh) as its neurotransmitter. Sympathetic and parasympathetic divisions function antagonistically to preserve a dynamic modulation of vital functions. These systems act on the heart respectively through the stellar ganglion and the vagus nerve. The interaction of these messages towards the sinoauricular node is responsible for normal cardiac variability, which can be measured by monitoring heart rate variability (HRV). Heart rate is primarily controlled by vagal activity. Sensorial data coming from the heart are fed back to the central nervous system. HRV is an indicator of both how the central nervous system regulates the autonomic nervous system, and of how peripheral neurons feed information back to the central level. HRV measures are derived by estimating the variation among a set of temporally ordered interbeat intervals. The state of perfect symmetry, which, in medical parlance, is called respiratory sinus arrhythmia (RSA), can be described as a state of cardiac coherence. Obtaining a series of interbeat intervals requires a continuous measure of heart rate, typically electrocardiography (ECG). Commercially available software is then used to define the interbeat intervals within an ECG recording. LITERATURE FINDINGS: The autonomic nervous system is highly adaptable and allows the organism to maintain its balance when experiencing strain or stress. Conversely, a lack of flexibility and a rigid system can lead to somatic and psychological pathologies. Several studies have shown a link between reduced HRV in postmyocardial infarction patients and increased risk for adverse cardiovascular events, including ventricular arrhythmias and sudden death. Recently, studies indicate that patients with depression and anxiety disorders exhibit abnormally low HRV compared with non-psychiatric controls. Reduced HRV seems indicate decreased cardiac vagal tone and elevated sympathetic activity in anxious and depressive patients and would reflect deficit in flexibility of emotional physiological mechanisms. A few studies have also revealed that biofeedback using respiratory control, relaxation and meditation techniques can increase HRV. For now, there is insufficient data to determine if paced respiration or subjective relaxation is necessary or sufficient for the efficacy of HRV biofeedback. Although the literature is modest, this review suggests that the use of biofeedback with relaxation and meditation approaches may result in increased HRV and parasympathetic activity. Limitations of the review literature have also been considered to identify areas for future research.

[Clinical and therapeutic characteristics of social phobia in French psychiatry (Phoenix study)]. / Les phobies sociales en psychiatrie: caractéristiques cliniques et modalités de prise en charge (étude Phoenix).

Only few clinical epidemiologic studies have been conducted on social phobia in France to date. It is however a frequent disorder, with often severe alteration of social adaptation and quality of life, and for which effective treatments exist. Thus, it seems really important to further explore how these patients are nowadays identified and treated in psychiatry. It was the objective of the Phoenix study. In this observational multi-center study, 952 psychiatric in- or out-patients, with a primary diagnosis of social phobia according to DSM IV criteria, were included. Numerous diagnostic and psychometric evaluations were carried out, in order to evaluate the comorbidity (Mini International Neuropsychiatric Interview, Hospital Anxiety and Depression Scale), the intensity of social anxiety (Liebowitz Social Anxiety Scale), and various aspects of the functional and emotional impact (Various Impact of Social Anxiety scale, Sheehan Disability Scale, SF-36, Positive and Negative Emotionality scale). The patients were in majority females (57.6%), with a mean age 37.5 years, and with a mean duration of social anxiety disorder 12.5 years. The mean scores of social anxiety on Liebowitz scale was 40.3 +/- 12.6 for the fear factor, and 38.3 +/- 13.6 for the avoidance factor. The generalized social anxiety subtype (anxiety in most social situations) was present in 67.8% of the patients. A major depressive disorder was found in 47.7% of the sample, and the prevalence of agoraphobia was even higher (49.2%). As known in clinical practice and in other studies, the prevalence rates of current alcohol dependence and substances abuse were also important in this population (respectively 10.6% and 12.7%). Mean scores of the Hospital Anxiety and Depression (HAD) sub-scales were 13.9 +/-3.8 for anxiety and 9.1 +/-4.5 for depression. About 15% of the patients had a history of suicide attempt, and a suicidal risk was present in nearly 40% of the sample. The psychosocial impact and the alteration of quality of life (with especially a poor physical health perception) were very significant, in the family, educational or occupational and social domains. Mean scores of the Sheehan Disability Scale were 6.1 +/- 2.6 for professional impairment, 5.0 +/- 2.7 for familial impairment, and 6.6 +/- 2.3 for social life impairment. In addition to the disability due to social phobia intensity, an important part of the burden was due to depressive symptoms. Approximately 60% of the patients had already a psychiatric treatment at the time of the survey (since 1,7 years in average), but only 17% had a cognitive behavioral therapy (CBT), and 48% had an antidepressant treatment. These proportions increased in a significant way after the consultation during which the investigation was carried out: an antidepressant was prescribed to 72% of the patients, and a CBT is proposed to 48%. On the whole, this study confirmed the severity and the morbidity of social phobia in a very large sample of French psychiatric patients. The depressive disorders, suicidal risk, and social impairment associated with this condition should incite to more detect and treat it. Seeing the long duration of the disease in our sample, and the lack of specific therapies in many cases, the identification and the treatment of social phobia must be improved, and the role of the psychiatrists in this process seems very important.

[The early maladaptive schemas: a study in adult patients with anxiety disorders]. / Les schémas précoces dysfonctionnels: étude chez des patients adultes souffrant d'un trouble anxieux.

The theory of early maladaptive schemas was initiated by Young, who postulated that each pathology is supported by one or several schemas. Adults with anxiety disorders more activate schemas that controls. This hyper activate schemas would go back the childhood. In this study, we measure some cognitive schema's activation, with the Schmidt and al. Questionnaire: this schema's questionnaire measures the dysfunctional schemas in actual way. Our purpose was to compare early maladaptive schema's activation of adults with anxiety disorders and adults healthy. The results indicate that each dysfunctional schema is more significatively activate by the adults with anxiety disorders that adults healthy. He doesn't exist schema typical of anxiety, but just a more important activation of all schemas of adults with -anxiety disorders. All subjects (with anxiety disorder and healthy) activate the schemas in the same order. It would appear that schema who imply an action of subject was more activate. So, in our study, we doesn't observe schema typical of anxiety, as opposed to postulate of Young and Klosko. In fact, in comparison with healthy subjects, all early maladaptive schemas of subjects with anxiety disorders were hypervalent. The order of schema's activation was the same in the two groups, but the activation in the anxious is always more important that in the healthy. All early maladaptive schemas would so hyperactivate in the anxious and a important activation of this schemas in the infancy would predispose to adult's anxious pathology. We consider this research as a preliminary work about early maladaptive schemas. In order to specify the research about schemas in the anxious, il will be interesting to observe this schemas according to different anxious disorders and to study prospectively the evolution of child's schemas.

Personality dimensions in social phobics with or without depression.

OBJECTIVE: This study investigated the personality traits of social phobics using the Temperament and Character Inventory (TCI). METHOD: A sample of 178 social phobics was assessed with the TCI, and compared with controls. The patients were classified into two groups, according to the absence (SP group) or to the presence (SP+D group) of depression. RESULTS: We found significant elevated scores for harm avoidance (HA) in social phobics when compared with controls (16.2 +/- 2.7), in both the SP (26.2 +/- 3.5), and the SP+D (28.9 +/- 4.7), groups. Lower self-directedness scores were found in the SP and in the SP+D groups when compared with the controls. Patients with the generalized type of social phobia had higher HA scores as compared with other social phobics. CONCLUSION: The personality profile obtained in these social phobics, whatever their depressive symptomatology, reflects a dramatically anxious and avoidant temperament associated to an immature character.

[Diagnosis and management of panic disorder in psychiatry (PANDA Study)]. / Etude sur le diagnostic et la prise en charge du trouble panique en psychiatrie (étude PANDA).

Panic disorder is a genuine public health problem given by their frequency and the various and repeated consultations that they involve. PD is underdiagnosed in primary care and in medical specialist. A public campaign might lead to improved diagnosis and better treatment of panic disorder, with a beneficial effect on medico-economic indicators. Intervention by the psychiatrist is of key importance, although it has not been evaluated to any great extend. The objective of the PANDA study was to look at the prevalence and diagnostic of panic disorder, the conditions of access to and use of care, as well as the method of treatment. Four hundred and twenty three psychiatrists participated in the study and 8,137 patients seen consecutively were included. The prevalence of actual panic disorder evaluated using the Mini International Neuropsychiatric Interview (MINI) systematic is 9%. In two third of cases coexisted agoraphobia and in one third a depression. Eighty six percent of patients with actual panic disorder were treated by the psychiatrists. The diagnosis and suitable treatment of panic disorder would appear to be a significant objective in term of public health, leading to a reduction in medical and social cost of this disorder.

[Is there an interpretational bias for childhood events in anxious adult patients?]. / Existe-t-il un biais d'interprétation des événements d'enfance chez les patients adultes anxieux?

During anamnesis, we attempted often to include the events reported by the patients in our own functional explanation of the disorder. We forget on one hand that the patient reports events intrinsically linked to his pathology, and on the other hand, that an event could not be understood without its context. Concerning the links between the pathology and what is narrated, it is known for a long time that the anxious disorders modify the perception of world by some processes, like the fast detection of the threat in the environment. Questions are: are the anxious encoding bias active to the restitution phase of information processing? Do these bias influence the recall of childhood events? In this article, we present theoretical data and set of experiments who leads us to say that anxious bias exist in the interpretation of childhood events made by anxious patients.

[Psychotherapy and education of anxious patients]. / Psychothérapies et éducation du patient anxieux.

Psychotherapy and education are and main component of the management of anxious patient. Psychoanalysis and cognitive behaviour therapies are the most indicate in anxiety. Because of the formation and the time required by their practice, they are a specialist field. A formation may be an help for the practitioner in the daily practice. Psychological care of anxiety is an important objective of public health to reduce the medical and social cost of this affection.

[What role does psychosocial environment play in anxiety?]. / Quel rôle joue l'environnement psychosocial dans l'anxiété?

Recent literature dealing with environmental life stress and anxiety is reviewed in this article. The role of psychosocial environment in both etiological and outcome factors of anxiety is evident and has been suggested by many theories. However, few studies have been conducted to explain this relation between life stress and anxiety. Mainly, studies have concerned recent life events and early separations. The link between life event and anxiety appears non specific and complex. Others factors may be taken in account like social context and coping styles. Recent models integrate both environmental factors and biological vulnerability. In particular, there has been an increasing focus on neurobiology of stress and anxiety. Further studies are necessary to specify the disorders and concepts under study and integrating biological and psychological factors in understanding the complex relationship of stress and anxiety.

[Treatment of adjustment disorder with anxiety: efficacy and tolerance of etifoxine in a double-blind controlled study]. / Traitement du trouble de l'adaptation avec anxiété: évaluation de l'efficacité et de la tolérance de l'étifoxine par un essai en double aveugle contre produit de référence.

Adjustment disorder with anxiety is defined as a clinically significant anxiety that occurs within 3 months after the onset of an identifiable psychological stressor. Recent studies indicate that this disorder is not uncommon and must be quickly identified and treated. However, few therapeutic trials have been done in relation with this disorder. According to the criteria set by DSM IV, 170 patients with a primary diagnosis of adjustment disorder with anxiety have been enrolled in a double blind multicenter controlled trial. Patients were treated for 4 weeks with etifoxine (150-200 mg/d), or buspirone (15-20 mg/d). Also both etifoxine and buspirone show clinical efficacy and safety, the two treatments are not equivalent. The global improvement score and the efficacy index are significantly improved in the etifoxine group. These results show the interest of using etifoxine in the treatment of adjustment disorder with anxiety and should be confirmed by further studies.

[Psychopathological disorders and coronary diseases]. / Troubles psychopathologiques et coronaropathies.

The role of psychological factors in the genesis of coronary diseases has been considered for a long time. Friedman took it upon himself to describe a personality profile (pattern A) constituting a risk factor for coronary heart disease of which, however, the practical interest seems limited. The association of psychopathological conditions and coronary heart disease has on the other hand not been extensively studied. Recent epidemiological data show that anxiety and depressive states represent a high comorbidity with coronary heart diseases. Panic attacks remain underestimated; they seem to participate in a complex physiopathological mechanism along with ischemic coronary heart diseases. Recent studies have shown that the existence of a depressive illness during coronary heart disease and particularly in the time period following a myocardial infarction, constitutes an independent risk factor, thus increasing the mortality rate. The evolution of coronary heart disease seems greatly influenced by the existence of anxious or depressive states, the diagnosis and the treatment of these states represent a major interest towards a better management of coronary patients.

[Life events and anxiety]. / Evénements de vie et anxiété.

During the last few decades many studies have examined the role of life events in psychiatric disorders. Majority of investigators have mainly focused on depression. Recently the specific etiological role of life events in anxiety have been reexamined. Two possible causal relationships have been hypothesized: loss or separation during childhood can serve as a predisposing factor for adult psychologic conditions and life events occurring in the months before the onset of anxiety disorder, can serve as a precipitating factor. However the main methodologic issue in life events research involves the distorting effect of time recall when life events are elicited retrospectively. Epidemiological and clinical data are consistent with the view that panic disorder is significantly and strongly associated with both parental death and separation in childhood. The relationship between recent life events and anxiety disorders remain unclear. Studies that compare recent life events of anxiety disorder subjects and controls have equivocal results. Different variables (number of events, type, impact) may play a role in anxiety. Recent data have also suggested that early and recent life events specially loss and separation may be a risk factor for secondary depression in anxiety. However, life events do not operate independently of other predispositional variables such as genetic, neurologic and cognitive factors. Further studies using a prospective design may be useful to clarify the relation between life events and anxiety.

Early life events and panic disorder: course of illness and comorbidity.

1. Some reports have suggested that there may be a link between the experience of traumatic life events in childhood and adolescence and the development of panic disorder in adults. In addition early loss event also seems increase depressive risk by a factor about two to three. 2. The authors wondered whether panic patients who experienced a traumatic life event would have a higher prevalence of subsequent major depressive episode than panic patients without history of depression. 3. One hundred fifty seven patients with panic disorder according DSM III-R criteria are included in this study. Fifty three (33.7%) had experienced a major loss or separation before the age of 15 years. 4. The panic group with early life events showed a significantly higher life time prevalence of major depression than the panic group who did not experience early life events.
