Thomas G. Brown, Ph.D., co-directeur de recherche / Objectifs : La capacité en matière de prise de décisions des récidivistes de conduite avec capacités affaiblies (CCA) semble les distinguer des non-contrevenants, particulièrement dans des situations ambiguës à haut risque, telles que la CCA. Cette étude exploratoire vise à vérifier l’hypothèse selon laquelle les récidivistes de CCA (R) auraient une moins bonne capacité de prise de décisions et une plus faible réponse de conductibilité électrodermale par anticipation à la tâche Iowa Gambling Task (IGT) que les non-contrevenants (C). Méthode : Vingt-trois récidivistes et 24 non-contrevenants ont été recrutés. Leur âge moyen (± É.T.) était 44.17(10.03) et 37.29 (10.60) ans respectivement. Les participants devaient être âgés de 18 ans ou plus, et avoir eu deux condamnations pour CCA ou plus pour le groupe R, et zéro CCA et un permis de conduire pour le groupe C. Les participants ont effectué I’IGT, une tâche neurocognitive de prise de décisions comprenant 100 sélections de cartes divisées en cinq blocs pour les analyses. On a comparé la performance du groupe R versus le groupe C à l’aide d’une ANOVA à mesures répétées [2 (groupe) x 5 (blocs)]. On a évalué la performance durant les blocs 1 & 2 (décisions dans l’ambiguïté) et blocs 3-5 (décisions sous haut risque) en utilisant des tests t post-hoc. Finalement, on a mesuré leur réponse de conductibilité électrodermale (RCEA) durant l’IGT. Résultats : L’ANOVA à mesures répétées des blocs 1 à 5 a révélé un effet significatif de l’interaction groupe par bloc, F(1,45)=5.28, p=.03, état carré =.11. Les tests t post hoc ont révélé une différence significative entre les groupes pour la combinaison des blocs 3 à 5, t(45) = 3.38, p = .002. Un effet d’interaction significatif a été détecté pour la RCEA des récidivistes de CCA versus celle des non-contrevenants, F(8,160)=2.33, p=.02, état carré =.10. Conclusion : Les récidivistes de CCA performent moins bien que les non-contrevenants à l’IGT. Ils persistent à prendre des décisions basées sur le potentiel de gains immédiats et négligent donc les risques de pertes. Ceci suggère qu’ils ont des déficits en matière de prise de décision, ce qui, en tant que groupe, les différencie des non-contrevenants. Une difficulté en matière de prise de décisions pourrait expliquer en partie le comportement impulsif fréquemment associé au récidivisme de CCA. Finalement, puisque les analyses de RCEA manquaient de puissance statistique, il est possible que de plus grands échantillons puissent permettre d’observer des différences entre les groupes de participants dans l’analyse de RCEA. / Objectives: Poor decision making in ambiguous high-risk situations, such as driving while impaired (DWI) by alcohol, may differentiate DWI recidivists from non-offenders. In this study, we test the hypothesis that DWI recidivists (R) will exhibit poorer decision-making performance on the Iowa Gambling Task (IGT), and in line with the Somatic Marker Hypothesis, weaker anticipatory somatic activation (using skin conductance response as index) than non-offenders (C, comparison group). Methods: DWI recidivists and non-DWI control drivers were recruited, [R (n=23) and C (n=24), mean ages (± SD) 44.17(10.03) and 37.29 (10.60) years respectively]. Participant selection criteria included ≥ 18 years old and ≥2 DWI convictions for group R and 0 DWI convictions lifetime and a driver’s license for group C. The participants performed the IGT, a decision-making neurocognitive task containing 100 card selection trials that we divided into 5 blocks for analyses. A 2 (group) x 5 (blocks) repeated measures ANOVA was used to compare group R performance on the IGT versus group C, followed by post hoc independent t-tests on aggregated blocks 1-2 (decision under ambiguity) & 3-5 (decision under high risk) to identify the source of group X block significant interactions. Two 3 (group) x 5 (blocks) repeated measures ANOVAs (for good decks and for bad decks) were used to compare the aSCR of groups C and R. Results: ANOVA repeated measures on blocks 1 to 5 produced a significant effect of group by block interaction F(1,45)=5.28, p=.03, partial ƞ2 =.11. Post hoc t-tests on aggregated blocks 3 to 5 were statistically significant, t(45) = 3.38, p = .002. A significant group x block interaction effect was found for good decks aSCR, F(8,160)=2.33, p=.02, partial ƞ2 =.10 . Conclusion: DWI recidivists performed more poorly than controls on the IGT, persistently making decisions based on potential immediate gains and neglecting associated loss risks and long-term outcome. This suggests they have reduced neurocognitive decision-making capacities distinguishable from the general population. While DWI recidivists’ behaviour appears as impulsive, these results suggest that their behaviour pattern involves decision-making difficulties. Larger sample sizes may be needed to detect a between-group effect in the aSCR analyses, as they were considerably underpowered.

Contexte : L'évolution des pratiques en alcoologie, suivant le modèle des soins centrés sur la patient, permet de revisiter le concept de rémission pour une meilleure prise en compte du point de vue du patient, participant de façon prépondérante dans la définition de ses objectifs thérapeutiques et dans leur évaluation. Pourtant, peu de ces critères subjectifs de l’évaluation du devenir des patients ont véritablement inclus le patient dans leur développement. Jusqu'à récemment, les instruments mesurant la qualité de vie les plus utilisés en alcoologie étaient génériques, constitués d'items générés par les experts et s'appuyant sur la littérature existante, mais n'ayant pas impliqué de patient dans leur développement, c’est-à-dire dans la génération des items. Méthodes : nous avons réalisé une revue systématique de la littérature recensant les essais thérapeutiques randomisés testant une intervention chez les patients alcoolodépendants, et mesurant son efficacité sur la qualité de vie. Nous avons répertorié les dimensions explorées dans les instruments existants. Il a été montré que ces instruments n'exploraient pas de façon optimale l’impact de l’alcoolodépendance sur la qualité de vie. Sur ce constat, nous avons développé conformément aux recommandations de la Food and Drug Administration (FDA) sur le développement des « Patients-Reported Outcomes » une échelle spécifique au trouble d'usage d'alcool, à partir du vécu rapporté par les patients. Nous avons utilisé la méthode des groupes focus, réalisés en parallèle en France et en Grande-Bretagne auprès de 38 patients présentant un trouble d’usage d’alcool. Ces groupes ont pu générer un pool d’items, testés secondairement par des entretiens cognitifs individuels auprès de 31 patients, aboutissant à l’échelle finale « Alcohol Quality of life Scale » (AQoLS). Nous avons ensuite validé l’échelle AQoLS sur un échantillon de 285 patients français présentant un trouble d’usage d’alcool, recrutés dans des centres sélectionnés de façon aléatoire en France. Résultats : L’échelle développée comporte 34 items, répartis selon 7 dimensions : les relations sociales, les activités, les conditions de vie, s’occuper de soi, les émotions négatives, le sommeil et la perte de contrôle. L’analyse de l’échelle a pu confirmer 6 de ces sept dimensions, avec une répartition légèrement différente des items. La dimension « s’occuper de soi » a disparu au profit d’une nouvelle dimension, l’estime de soi. Les dimensions de contrôle et d’estime de soi sont novatrices dans un instrument de qualité de vie liée à la santé, chez l’adulte. L’échelle a montré de bonnes propriétés psychométriques, avec une bonne consistance interne (Cronbach = 0.96), et une corrélation modérée mais significative avec certains sous-scores de la SF-36 et l’EQ-5D. Un travail complémentaire qualitatif a pu illustrer les liens entre les différents domaines impactés, et notamment la proximité de perception dans les propos des patients, entre l’estime de soi, la perte de contrôle et les troubles cognitifs. Conclusion : L’évolution vers un modèle des soins centrés sur le patient permet d’envisager une conception différente de la rémission et de construire et valider une mesure de la qualité de vie se rapprochant des préoccupations des patients, l’échelle AQoLS. Deux dimensions novatrices ont été rattachées à ce concept : la perte de contrôle du point de vue du patient, et l’estime de soi. / Context : The evolution of practices in alcohol use disorder field, following the model of patient-centered care, lets revisit the concept of remission for a better consideration of the patient's point of view, participating predominantly in the definition of therapeutic objectives and in their assessment. Yet few of these subjective criteria of the evaluation of patient outcomes have actually included the patient in their development. Until recently, quality of life instruments the most used among patients with alcohol use disorder were generic ones, and their development and particularly generation of items did not involve patients, but rather experts and were based on existing literature. Methods : we conducted a systematic literature review identifying randomized clinical trials testing an intervention in alcohol-dependent patients, and measuring its effectiveness on quality of life. We have listed the dimensions explored in the existing instruments. It has been shown that these instruments did not optimally explore the impact of alcohol dependence on quality of life in this population. On this, we have developed a scale specific for patients with alcohol use disorder, following the recommendations of the Food and Drug Administration (FDA) on the development of "Patient-Reported Outcomes", namely involving patients extensively. We used the method of focus groups conducted in parallel in France and Great Britain with 38 patients with alcohol use disorder. These groups allowed the generation of a pool of items, secondarily tested by individual cognitive interviews with 31 patients, resulting in the final scale "Alcohol Quality of Life Scale" (AQoLS). We then validated the AQoLS scale on a sample of 285 French patients with alcoho use disorder, recruited from randomly selected centers in France. Results: The scale has 34 items developed, distributed in seven dimensions: social relationships, activities, living conditions, looking after self, negative emotions, sleep and loss of control. The validation study confirmed six of the seven dimensions, with a slightly different distribution of the items. The "looking after self" dimension disappeared in favor of a new dimension of self-esteem. Control and self-esteem dimensions are innovative in a health-related quality of life instrument in adults. The scale showed good psychometric properties, with good internal consistency (Cronbach = 0.96), and a moderate correlation with sub-scores of the SF-36 and EQ-5D. A qualitative complementary work could illustrate the links between the different affected areas, including the proximity in patients’ perception between self-esteem, loss of control and cognitive impairment. Conclusion : The move towards a model of patient-centered care allows considering a different approach of remission and to build and validate a measure of health-related quality of life close to the concerns of patients with a alcohol use disorder, AQoLS scale. Two innovative dimensions were attached to this concept: loss of control from the patient's perspective, and self-esteem.

The inventory was translated and, posteriorly, applied on people with different reading levels to certify that the items are understandable to public in general, from diverse places of the country, divided into clinical and non-clinical groups. Were evaluated 2855 subjects between the ages of 18 and 85 years old, male and female, resident and dwellers of Brazilian cities. The application methods were face-to-face and computerized. Results showed that the clinical group presented significant differences between the means in comparison to the non-clinical group. Through the application of the General Health Questionnaire were developed studies related to the achievement of convergent validity and its results pointed to the relation between the instrument scores and the MCMI-III. The Alcohol Dependence Scale analysis indicated that people who reported abusive use of alcohol had highest scores, indicating adequacy of the instrument on identifying manifestation of disorders and syndromes. Nevertheless, further studies are necessary to the establishment of normative patterns to the Brazilian sample / Esse estudo tem como principais objetivos traduzir e adaptar o MCMI-III para o portugu?s brasileiro, bem como investigar e analisar as modifica??es envolvidas na escala de Depend?ncia de ?lcool do instrumento original em rela??o aos resultados obtidos na validade e no processo de adapta??o para o Brasil. O invent?rio foi traduzido e posteriormente administrado em pessoas com n?veis variados de leitura para certificar-se de que os itens pudessem ser compreendidos pelo p?blico em geral, de diversos locais do pa?s, divididos em grupo cl?nico e grupo n?o cl?nico. Foram avaliados 2855 sujeitos com idades de 18 a 85 anos, dos sexos feminino e masculino, residentes e domiciliados em cidades brasileiras. As formas de administra??o foram modo presencial e modo informatizado. Os resultados demonstraram que o grupo cl?nico apresentou diferen?as significativas entre as m?dias com rela??o ao grupo n?o cl?nico.

The diploma thesis Influence of alcohol on road traffic accident rate in the South Bohemian Region by comparison of the years 2008 2012 is aimed at comparing the influence of alcohol on road traffic accidents in the districts of the South Bohemian Region in the period 2008 2012 as well as outlining the effects of road traffic accidents due to alcohol with regard to partial circumstances of particular accidents (according to accident type, accident effects, age of the perpetrators of accidents) in the years 2008 2012. The comparison was based on police statistics of road traffic accident rates of the Regional Police Headquarters for the South Bohemian Region, the Road Traffic Inspectorate in České Budějovice. The thesis attempted to perform a survey of the problems related to accidents caused by driving under the influence of alcohol. The theoretical part deals with two spheres connected with alcohol-related road traffic accidents. The practical part focuses on the effects of the accidents which happened in the South Bohemian Region in the years 2008 2012, and on the effects of accidents caused due to alcohol in the South Bohemian Region in the years 2008 2012.

Alcohol use disorders (AUDs), and alcohol dependence (AD) in particular, are prevalent and associated with a large burden of disability and mortality. The aim of this study was to estimate prevalence of AD in the European Union (EU), Iceland, Norway, and Switzerland for the year 2010, and to investigate potential influencing factors. The 1-year prevalence of AD in the EU was estimated at 3.4% among people 18–64 years of age in Europe (women 1.7%, men 5.2%), resulting in close to 11 million affected people. Taking into account all people of all ages, AD, abuse and harmful use resulted in an estimate of 23 million affected people. Prevalence of AD varied widely between European countries, and was significantly impacted by drinking cultures and social norms. Correlations with level of drinking and other drinking variables and with major known outcomes of heavy drinking, such as liver cirrhosis or injury, were moderate. These results suggest a need to rethink the definition of AUDs.

Worldwide, alcohol is the third leading risk factor for disease burden, while its harmful use leads to 2.5 million deaths every year. Alcohol dependence (AD) is a complex disease, with devastating effects on individuals, families, and society. It is estimated that 76.3 million people worldwide have suffered from alcohol use disorders (AUD), including alcohol abuse and AD. Alcohol withdrawal or alcohol withdrawal symptom (AWS) refers to a cluster of symptoms that may occur when a heavy drinker suddenly stops or significantly reduces their alcohol intake. These symptoms can start as early as 2 h after the last drink, persist for weeks, and range from mild anxiety and shakiness to severe complications, such as seizures and delirium tremens. Family, twin, and adoption studies have indicated that genetic and environmental factors and their interactions contribute to the development of AD and related phenotypes, with a heritability coefficient of more than 0.5 for AD. Whole-genome linkage and candidate gene association studies have successfully identified several chromosome regions and genes that are related to AD and AWS. Furthermore, gene expression analysis, epigenetic studies, and genome-wide association studies (GWAS) have provided regions and loci for AWS. This chapter reviews the recent findings in genetic studies of AWS.

German text / Die Alkoholabhängigkeit ist die am stärksten verbreitete Abhängigkeitserkrankung in Deutschland. Unbekannt ist die Zahl der betroffenen Angehörigen. Nach Erarbeitung not-wendiger theoretischer Grundlagen und Vorstellung aktueller Forschungsergebnisse stan-den narrative Interviews mit Frauen von alkoholabhängigen Partnern im Mittelpunkt der Forschungsarbeit. Durch Datenanalyse und Dateninterpretation mit Methoden der rekon-struktiven Sozialforschung wurde ein tieferes Verständnis für die Lebensgeschichte der beiden ausgewählten Biografinnen gewonnen. Risiko- und Schutzfaktoren konnten diffe-renziert erfasst und resilienzfördernde Maßnahmen für Seelsorge und Beratung abgeleitet werden. Besondere Beachtung fand die Bedeutung des christlichen Glaubens als Resilienz-faktor. Weitere Beobachtungen durch Einbeziehung aller Interviews als Datenmaterial wurden als Hilfen für das Verständnis der Gesamtproblematik ausgewertet. Aus der Dis-kussion der Ergebnisse ergaben sich Handlungsempfehlungen für die christliche Gemeinde und richtungsweisende Impulse für Seelsorge und Beratung. Schlüsselbegriffe: / Alcohol dependence is the most widespread addictive disease in Germany, the number of affected relatives unkown. After acquiring theoretical foundations and current research results, my research focused on narrative interviews with wives of alcohol dependent part-ners. By the use of reconstructive social research methods, data analysis and interpretation a deeper understanding of the life history of the two selected biographers was obtained. After detecting risk and protective factors, resilience promoting factors for pastoral care and counselling could be derived. Special attention was paid to the importance of Christian faith. For an understanding of the overall problem, all interviews were included as data material and evaluated. From the discussion of the results, recommendations for the Chris-tian Church and impulses giving direction for pastoral care and counselling were derived. / Practical Theology / M. Th.
