In 2011, a report of the Federal Public Service have shown that 8.5% of the Belgian population suffers from chronic pains, which represents 938 300 belgian people (Berquin et al., 2011). These persistent pains may result in functional limitations on both domestic and professional domains which may lead to temporary or permanently work incapacity (Faymonville et al., 2014). These incapacities may in turn cause a social withdrawal and a tendency to focus on pain (Berquin et al., 2011). Additionally, patients are prone to emotional modifications due to persistent pain (Ossipov et al., 2010). All of these factors may contribute in the emergence of anxiety and depressive symptoms. The present study examines the impact of type of work incapacities (at work, temporary incapacity and permanent incapacity) on anxiety and depression scores as a function of diagnoses (fibromyalgia, chronic pain syndrome, back pain, polyalgia). 123 patients suffering from chronic pain completed a measure of anxiety and depression (HADS), and a self-reported questionnaire of psychological and physical disability at work. We did not found any significant effect of type of work incapacities on anxiety and depression scores. Results present tables of frequencies to illustrate the social and professional situations of patients as a function of chronic pain diagnoses. [less ▲]

Fatigue is one of the most frequent symptom in multiple sclerosis patients (MS patients). We showed significant correlations between fatigue levels and difficulties encountered by our patients at work evaluated through a specific questionnaire we already validated . This complaint must be carefully managed by professionnals in order to help the patients cope with it in the best way for maintaining work situation. [less ▲]

The purpose of this paper is to present the construction and validation of a questionnaire in order to evaluate the specific work difficulties and compensation mechanisms developed by multiple sclerosis patients (MS). At the moment, only few very recent questionnaires (in English) are constructed in order to highlight the link between the patients’ cognitive deficits with their professional situation (Doogan & Playford, 2014; Honan et al., 2012; McFadden et al., 2012). This lack of accurate assessment is detrimental to the patients’ job retention. Our questionnaire was constructed from review of literature and interviews of patients and experts. In order to validate our questionnaire and to test its specificity to MS patients, three groups of participants answered the questionnaire: MS patients, diabetic patients (diabetes is also a chronic illness but without any cognitive deficits contrary to MS) and a control group. We controlled the effect of anxiety and depression and we conducted a factorial analysis that showed the existence of 3 factors: the ergonomic factor (that includes cognitive difficulties and resources and adaptation process), the description of work situation and the social support. The three groups of participants obtained similar results for the work description and the social support while the group of patients with MS obtained a higher score than the other 2 groups for the ergonomic factor. These results suggest that our questionnaire is specific to the MS population and to the difficulties they specifically meet in their work situations. These results highlight new research opportunities and specific ways to increase job retention in MS population. [less ▲]

Drowsiness is one of the major factors explaining accidents, particularly in traffic accidents but also in work situations with serious consequences (e.g. medicine). The drowsiness may be assessed by diverse measures that vary from physiological and unconscious data (e.g. EEG) to subjective and conscious evaluation. In their daily life, people are used to evaluate their drowsiness by subjective assessment and research observes a great inter-individual variation in this evaluation. Moreover, the subjective evaluation is dependent on the situation and the risk perceived by the person (e.g., new versus usual situations, simple versus complex environments, etc.). In this theoretical context, our purpose was to investigate the links between 1) objective performance (reaction time) measured by a psychomotor vigilance task (PVT), 2) data from eye movements and 3) subjective assessment of drowsiness (measured with Karolinska Sleepiness Scale, KSS). 12 persons, aged from 20 to 56, participated individually. They were asked to respect a 60% sleep deprivation during the night before the experiment and to not drink any energy drinks the day of the experiment. The experiment was conducted between 1 and 3 PM after a heavy lunch in order to increase the circadian effect. Moreover, the temperature of the room was 25° in order to increase drowsiness. Each participant was asked to perform 4 PVT. However, although 100% of participants performed the first two PVT, only 66% were able to perform the third PVT and only 33% of participants performed the fourth and last PVT. Our results showed an effect of time on objective performance, eye movements and subjective assessment of drowsiness in PVT 1 and 2: significant increase of reaction time, increase of eye closure and perclos, reduction of pupil diameter and increase of subjective drowsiness estimation (KSS). Only the frequency and duration of blinks remained constant across time. In PVT 3 and 4, data from eye movements and objective performance (reaction time) did not vary anymore across the time. Only the subjective estimation of drowsiness (KSS) continued to increase. Furthermore, subjective estimation of drowsiness was differently correlated with eye movements and objective performance across the PVT; it was significantly correlated with reaction time (PVT 1,2,3), blink frequency and duration (PVT 1,2,3), perclos (PVT 1,2,3,4), eye closure (PVT 2,3), pupil diameter (PVT 1,2,3,4). These results are discussed and integrated in an ergonomic approach in order to analyze the links between objective performance, eye movements and subjective assessment of drowsiness. [less ▲]

In the framework of the design process of a multimodal 3D simulation environment to support architects’ acoustic tasks, we wanted to gain a better understanding of how architects are able to discriminate the sounds using audio and/or visual inputs. This study explores how 2D pictures of rooms do support or impede the auditory evaluation of a space (specifically reverberation). The paper describes an experiment evaluating participants rankings of perceived acoustic reverberation when presented with congruent (coherent) or non-congruent (conflicting) evocative pictures of architectural spaces. We found that the congruent pictures had a positive impact on task performance while the noncongruent pictures had no significant effect. Moreover the effect of the expertise (professional background) of participants was investigated. We found differences between architects and non-architects in the way they performed the task, and they processed reverberation assessments. Taken together, the findings of this study contribute to the question of usefulness of expensive multimodal 3D simulation environment. [less ▲]

This article aims to establish a "profile" of patients presenting with chronic pain in the algology service of CHU of Liège to identify possible relationships between diagnoses, psychological states and modes of pain management. Between 2005 and 2010 we monitored 1832 individual chronic pain patients who attended our pain clinic at the University Hospital of Liège. This paper presents the characteristics of these patients and their test scores before the treatment to assess their health status in a biopsychosocial perspective. Demographic and lifestyle as well as occupational factors, pain disability index, pain belief assessment, hospital anxiety and depression scale, SF-36 (Short Form Health Survey) and pain visual analogue scale are presented. The results have clinical implication; they suggest an adaptation of our therapeutic interventions based on these observations. © 2014 Springer-Verlag France. [less ▲]

Dans cet article, nous n’avons pas la prétention de faire un exposé exhaustif sur la communication thérapeutique. Nous invitons le lecteur à observer un regard critique sur nos échanges verbaux et non verbaux. Nous montrons notamment comment les mots peuvent être porteurs de suggestions négatives et avoir un « effet nocebo » et comment l’apprentissage de compétences communicationnelles constitue un outil puissant permettant d’améliorer la qualité des soins et le bienêtre au travail [less ▲]

The purpose of this paper is to present the construction of a questionnaire in order to evaluate the specific work difficulties and compensation mechanisms developed by multiple sclerosis patients (MS). At the moment, it does not exist any questionnaire that links the patients cognitive deficits with their professional situation. This lack of accurate assessment is detrimental to the patients job retention. Our questionnaire was constructed from review of literature and interviews of patients and experts. Three groups of patients answered the questionnaire: MS patients, diabetics patients and a control group. We controlled the effect of anxiety and depression and we conducted a factorial analysis that showed the existence of 3 factors: the ergonomics factor (that includes cognitive difficulties and resources and adaptation process), the description of work situation and the social support. The three groups of participants obtained similar results for the work description and the social support while the group of patients with MS obtained a higher score than the other 2 groups for the ergonomics factor. These results suggest that our questionnaire is specific to the MS patients population and to their difficulties they met in their work situations. These results offered also some ways to increase job retention in MS patients population. [less ▲]

L’objectif de cette étude est de présenter une méthodologie d’analyse des communications multimodales dans les situations de conception collective. Cette méthodologie permet de décrire quelles sont les modalités de communication qui supportent particulièrement l’élaboration du common ground, zone de partage indispensable pour l’efficacité de la communication, et donc pour la performance collaborative. La méthode présentée vise également à pouvoir identifier les articulations pertinentes entre modalités de communication, dans le sens où elles favorisent l’élaboration de ce processus. Dans une première phase de notre recherche, nous avons observé et analysé les échanges multimodaux tels qu’ils prennent place en situation « naturelle » (ou non-médiatisée) dans le but de prétester notre méthode, mais également de pouvoir comparer cette situation avec les situations de collaboration distantes et outillées par des nouvelles technologies que nous envisagerons par la suite.
