It was a transversal, analytical research. Subjects and Methods: The stratified sample was 212 students from a private university that used Facebook, Instagram and/or Twitter. To measure depressive symptoms, Beck Depression Inventory was used, and to measure the dependence to social media, the Social Media Addiction Test was used, adapted from the Internet Addiction Test of Echeburúa. The collected data were subjected for analysis by descriptive statistics where STATA12 was used. Results: The results show that there is an association between social media dependence and depressive symptoms (PR [Prevalence Ratio] = 2.87, CI [Confidence Interval] 2.03–4.07). It was also shown that preferring the use of Twitter (PR = 1.84, CI 1.21–2.82) over Instagram (PR = 1.61, CI 1.13–2.28) is associated with depressive symptoms when compared to the use of Facebook. Conclusion: Excessive social media use is associated with depressive symptoms in university students, being more prominent in those who prefer the use of Twitter over Facebook and Instagram. / Revisión por pares

The primary purpose of this study was to examine the underlying latent factor structure of the Trauma Inventory for Partners of Sex Addicts (TIPSA), a 53-item assessment designed to assess for Post-Traumatic Stress Disorder (PTSD) in the context of sexual addiction. It was theorized that the factor structure mirrored the 5 core criteria for PTSD as constituted in DSM-5. Data were gathered from 3,199 self-selected respondents (ages 21 to 55) who completed an online version of the TIPSA. Confirmatory Factor Analysis (CFA) was performed utilizing Mplus in order to confirm the hypothesized factor structure of the TIPSA. Several modifications were made to the model, based on factor loadings and modification indices, in order to improve goodness-of-fit. In addition to the original posited model, three other models were also examined: a second-order factor model; a general-factor model; and a bifactor model. The second-order factor model emerged as the model of choice, based on both statistical and theoretical underpinnings. As a result of the findings from this study, revision of the items contained in the TIPSA is recommended. In addition, in order to further establish the validity of the TIPSA as an assessment for PTSD, evaluating convergent and discriminant validity of the TIPSA with other established assessments, such as the National Institutes of Mental Health (NIMH) PTSD Checklist, is also suggested.

Les addictions constituent un problème majeur de santé publique et soulèvent de nombreuses questions sur le plan clinique et psycho-pathologique ainsi que sur leur prise en charge. Toutefois, si elles sont d’un intérêt certain dans le domaine de la recherche scientifique, ce n’est que récemment que la souffrance des proches, et plus encore celle des parents de jeunes adolescents, sont l’objet de travaux pour les chercheurs comme pour les professionnels.L’objectif de cette recherche qualitative et exploratoire est d’étudier les vécus des parents d’adolescents ayant des pratiques addictives. Elle est réalisée au sein d’un dispositif de prévention en addictologie.Ce sont en majorité des mères qui consultent pour leurs fils. Généralement, ces adolescents ou jeunes adultes sont âgés entre 15 et 23 ans, aux prises avec un problème de consommation de cannabis, d’alcool, de jeux vidéo et vivent chez leurs parents.Six formes de vécus parentaux et certaines configurations familiales en lien avec les conduites addictives des adolescents ont pu être identifiées à l’aide de quinze vignettes cliniques.Les addictions des jeunes interpellent la fonction maternelle, en tant que médiatrice de la fonction paternelle. De même, le sujet adolescent convoquerait chez la mère, un objet répondant à la question du réel d’une autre jouissance, en tant qu’une suppléance à l’absence de signifiant.Ces résultats permettent d’interroger les possibilités d’interventions en clinique auprès de ces familles d’une part, et de réfléchir à un nouveau dispositif d’accompagnement médico-psycho-social d’autre part. / Addiction constitutes a major public health problem and raises numerous questions from a clinical and psychopathological perspective as well as on young users’ care. Even though certain interest has been shown in the field of scientific research on the subject, only recently has the suffering of the parents of young teenagers been the object of researchers’ and professionals’ studies.The objective of this qualitative and exploratory study is to examine the personal experiences of the parents of teenagers suffering from addiction. It was carried out at a prevention and treatment center for addiction.Mothers who consult for their sons make up the majority of those who consult. Generally, these teenagers or grown-up young adults are between the ages of 15 and 23, live at home with their parents, and battle against excessive use of cannabis, alcohol, and video games.Six forms of parental personal experiences and certain family configurations in connection with the addictive behaviors of the teenagers were identified by means of fifteen clinical cases.The addictions of the young people in question call out to the maternal function as a mediator of the paternal function.Additionally, the adolescent subject summons within his/her mother an object in response to the question of the real of the Other jouissance, as a substitution in the absence of the signifier.These results allow us to question the possibilities of clinical interventions with these families, and to think about new tools of medical-psychosocial support.

In clinical practice, sufficient attention is paid to the substance dependencies in many respects. Despite being similar to these dependencies, the issue of "activities, behavior, processes" is often left aside. This work deals with online computer games, mostly with the World of Warcraft (WoW), because there are players who may have a problem not only in relation to addictive behavior. The aim of the research was to describe the psychopathological characteristics of MMORPG players and describe the connection between their occurrence and the rate of reported addictive behavior. Participants were MMORPG active players recruited by self-selection based on addressing through online discussion forums, facebook pages and e-mail snowball. The minimum range of subjects was set at 100 players. Tool for gathering data was online questionnaire. The results were determined using descriptive- analytical and mathematical statistics with the help of SPSS software. The final group consists of 243 respondents, of which 216 are men (89%) and 27 women (11%). The age range of the respondents is between 10-56 years, the average age is 22 years. 185 respondents (76%) considered WoW as being their first choice game. Of 243 respondents 23 (it is about 10%) have shown addictive behavior (including 22 men and 1 woman)....

O jogo patológico se caracteriza pela perda do controle de apostar em jogos de azar e pelo comportamento persistente apesar dos prejuízos causados. Uma das características centrais do comportamento de jogadores patológicos é a fissura de jogar para evitar estados emocionais desfavoráveis e sintomas de ansiedade e de depressão estão significativamente associados à intensidade da fissura em jogadores patológicos. Assim, é possível que o tratamento da depressão e da ansiedade esteja associado indiretamente à melhora do comportamento de jogar, através da redução da fissura. Sabemos que a saúde mental pode ser influenciada positivamente pela prática de atividade física. Diversos estudos sugerem que a prática de exercícios tem efeito positivo sobre o humor, se associa à redução da ansiedade e da depressão, possibilitando melhor controle do estresse. O objetivo principal deste trabalho foi examinar o impacto de um programa de atividade física sobre a sintomatologia ansiosa e depressiva e sobre a fissura por jogo em uma amostra de 33 jogadores patológicos em início de tratamento ambulatorial. Adicionalmente, analisamos a associação entre a fissura e níveis dos hormônios relacionados ao estresse. O tratamento consistiu em terapia cognitivocomportamental ou psicoterapia psicodinâmica em grupo e tratamento psiquiátrico das comorbidades associadas. O programa de atividade física variou de 4 a 8 semanas e consistiu em 8 sessões de 50 minutos cada de exercícios aeróbios de intensidade moderada (60-75% da freqüência cardíaca máxima). A fissura durante o exercício foi avaliada imediatamente antes e depois de cada sessão de atividade física. Também foi avaliada a fissura por jogo nas 24 horas anteriores e nos 7 dias anteriores. Os pacientes foram investigados no início e ao final do programa de atividade física quanto a comportamento de jogo, intensidade de sintomas depressivos e ansiosos e níveis plasmáticos dos hormônios adrenocorticotrófico (ACTH), cortisol e prolactina. Os resultados mostram que houve redução significativa da fissura por jogo após cada sessão de atividade física e ao final da intervenção. Houve melhora nos sintomas de ansiedade, depressão e do comportamento de jogo. A redução da fissura por jogo durante o exercício físico se relaciona com a redução da fissura e da ansiedade ao final do programa, mas não à sintomatologia depressiva. Ainda, se associa à variação da prolactina, mas não à variação de cortisol e ACTH / Pathological gambling is characterized by loss of control over gambling and this behavior persists despite losses caused by this activity. One of the central features of the behavior of pathological gamblers is craving for gambling in order to avoid adverse emotional states, and symptoms of anxiety and depression are significantly associated with the intensity of craving among pathological gamblers. Thus, it is possible that the treatment of depression and anxiety is indirectly associated with improvement of gambling behavior by reducing the craving. We know that mental health can be positively influenced by physical activity. Several studies suggest that exercise has a positive effect on mood, is associated with reduced anxiety and depression, enabling better control of stress. The main objective of this study was to examine the impact of a program of physical activity on depressive and anxiety symptoms and the craving for gambling in a sample of 33 pathological gamblers in early outpatient treatment. Additionally, we analyzed the association between craving and levels of hormones related to stress. The treatment consisted of cognitive-behavioral or psychodynamic therapy group and treatment of psychiatric comorbidities. The physical activity program included 8 sessions ranging from 4 to 8 weeks. The proposed activity consisted of 50 minute sessions, aiming at 60-75% of maximum heart rate. Craving during exercise was assessed immediately before and after each session. We also analyzed the gambling craving in the previous 24 hour and 7 day period. Patients were investigated at the beginning and at the end of the program of physical activity regarding gambling behavior, intensity of depressive and anxiety symptoms, and plasma levels of adrenocorticotropic hormone (ACTH), cortisol and prolactin. The results show a significant reduction in gambling craving following each session of physical activity and at the end of the program. There was improvement in symptoms of anxiety, depression, and gambling behavior. The reduction in craving after each session is associated with the reduction of craving and anxiety at the end of the program but not with depressive symptomatology. Still, craving reduction is associated with variation in prolactin levels, but not in cortisol and ACTH levels

L’objectif général était d'étudier les liens entre les conduites addictives et différents aspects de la vie professionnelle dans l’infrastructure de recherche CONSTANCES : (1) Estimer les prévalences d'usage de substances en population générale française en fonction des facteurs sociodémographiques et cliniques, (2) Étudier les associations longitudinales entre stress au travail et usage chronique de benzodiazépines, (3) Étudier les associations transversales entre demande émotionnelle au travail et usages d’alcool, de tabac et de cannabis, (4) Étudier les associations transversales entre demande émotionnelle au travail et usage chronique de benzodiazépines, (5) Étudier les associations longitudinales entre usages d’alcool, de tabac et de cannabis et la perte d’emploi.1. Les prévalences d'usage d'alcool, de tabac et de cannabis en population générale ont été estimées. Concernant l’usage chronique de benzodiazépines, sa prévalence était en 2015 de 2,8 % (IC 95% : 2,3-3,4) chez les hommes et de 3,8% (IC 95 % : 3,3-4,5) chez les femmes(n = 9 535).2. Il existait des relations dose-dépendantes entre l’intensité du stress au travail, mesuré par le déséquilibre effort-récompense, et le risque d’usage chronique de benzodiazépines sur une période de suivi de deux ans (n = 31 077), avec un OR = 2,18 (IC 95 % : 1,50-3,16) pour les sujets les plus stressés comparés aux moins stressés, après ajustement pour les facteurs sociodémographiques, les usages d’alcool et de tabac, la dépression et l’état de santé perçu.3. Il existait des associations significatives entre la demande émotionnelle au travail, mesurée par la fréquence de l’exposition stressante au public, et les usages d’alcool, de tabac et de cannabis, en ajustant pour les facteurs sociodémographiques (n=23 641). Concernant l’usage d’alcool, la demande émotionnelle était associée chez les hommes à une augmentation du risque d’alcoolisations paroxystiques intermittentes plus d’une fois par mois (OR = 1,29 (IC 95 % : 1,10-1,51), et chez les femmes à une augmentation des risques de consommation hebdomadaire élevée ou très élevée (OR = 1,59 (IC 95 % : 1,12-2,25) et de trouble de l’usage d’alcool (OR = 2,30 (IC 95 % : 1,54-3,44).4. Il existait des relations dose-dépendantes entre la demande émotionnelle au travail et l'usage chronique de benzodiazépines, en ajustant pour l’âge, le niveau d’éducation et l’indice de déprivation sociale (n=33 195). Les OR étaient de 2,3 (IC 95 % : 1,5-3,6) chez les hommes et de 2,5 (IC 95 % : 1,8-3,4) chez les femmes pour les individus exposés à la plus forte demande émotionnelle comparée à la plus faible. Ces associations persistaient en l’absence d’autres facteurs de vulnérabilité à l’usage des benzodiazépines.5. Les usages d’alcool, de tabac et de cannabis étaient tous associés, de manière indépendante, et suivant des relations dose-dépendantes, au risque de perte d’emploi à un an, en ajustant pour l’âge, le genre, la dépression et l’état de santé perçu(n=18 879). Le risque de perte d’emploi associé à un usage problématique ou de dépendance probable de l’alcool était de 1,92 (IC 95 % : 1,34-2,75) comparé à un usage à faible risque. Il était de 1,78 (IC 95 % : 1,26-2,54) pour les gros fumeurs comparés aux non-fumeurs et de 2,68 (IC 95 % : 2,10-3,42) pour les consommateurs de cannabis au moins une fois par mois comparés aux non-consommateurs.Ces résultats pourraient permettre aux décideurs en santé publique et en santé au travail d'élaborer des stratégies d'information et de prévention destinées à réduire l'usage de substances, notamment en milieu professionnel. En raison de la complexité des interrelations entre conduites addictives et vie professionnelle, ce champ de recherche en épidémiologie devrait poursuivre son développement afin de répondre aux enjeux majeurs de santé publique posés tant par les conduites addictives que par l'exposition aux risques professionnels. / The overall objective was to explore the links between addictive behaviours (alcohol, tobacco, cannabis, benzodiazepines) and different aspects of occupational life (i.e. job stress, emotional demand, job loss) using data from the CONSTANCES research infrastructure.This general objective has been operationalized into five distinct objectives:(1) Estimate the prevalence of substance use in the general population according to socio-demographic and clinical factors,(2) Examine the longitudinal associations between job stress and benzodiazepine long-term use,(3) Examine the cross-sectional associations between emotional job demand and alcohol, tobacco and cannabis use,(4) Examine the cross-sectional associations between emotional job demand and benzodiazepine long-term use,(5) Examine the longitudinal associations between alcohol, tobacco and cannabis use and job loss.1. The prevalence of alcohol, tobacco and cannabis use in the general population have been estimated. The prevalence of benzodiazepine long-term use in 2015 was of 2.8 % (CI 95 % : 2.3-3.4) in men and 3.8 % (CI 95 % : 3.3-4.5) in women (n=9 535).2. There were dose-dependent relationships between job stress, as measured by the effort-reward imbalance, and the risk of benzodiazepine long-term use over a two-year follow-up (n=31 077), with an OR = 2.18 (CI 95 % : 1.50-3.16) for the most stressed compared to the least stressed subjects, after adjusting for socio-demographic factors, alcohol and tobacco smoking use, depression and self-rated health status.3. There were significant associations between emotional job demand, measured by the stressful exposure to the public in the workplace, and alcohol, tobacco and cannabis use, after adjusting for socio-demographic factors (n=23 641). Regarding alcohol use, emotional job demand was associated in men with an increased risk of heavy episodic drinking more than once a month(OR = 1.29 (CI 95 % : 1.10-1.51), and in women with an increased risk of high or very high weekly consumption (OR = 1.59 (CI 95 % : 1.12-2.25) as well as with alcohol use disorder(OR = 2.30 (CI 95 % : 1.54-3.44).4. There were dose-dependent relationships between emotional job demand and benzodiazepine long-term use, adjusting for age, education level and social deprivation index (n=33 195). ORs were 2.3 (CI 95 % : 1.5-3.6) in men and 2.5 (CI 95 % : 1.8-3.4) in women for individuals exposed to the highest emotional demand compared to the lowest. These associations remained significant even without other factors of vulnerability to benzodiazepine use.5. Alcohol, tobacco and cannabis use were independently and dose-dependently associated with the risk of job loss at one-year, adjusting for age, gender, depression and self-rated health status (n=18 879). The risk of job loss associated with problematic use or alcohol dependence was 1.92 (CI 95 % : 1.34-2.75) compared to low-risk use. This risk was 1.78 (95% CI : 1.26-2.54) for heavy smokers compared to non-smokers and 2.68 (CI 95 % : 2.10-3.42) for cannabis users at least once a month compared to non-users.These findings could help public health and occupational health decision-makers to develop information and prevention strategies aiming at reducing the burden of substance use, particularly in the workplace. Because of the complexity of the interrelationships between addictive behaviours and occupational life, this field of the epidemiologic research should continue to be developed in order to meet the major public health challenges posed by both addictive behaviours and exposure to occupational risks.

Resources: The topic of this Master's thesis is oniomania, or in other words, pathologic shopping and how it is affected by an individual's materialistic value orientation. Pathologic shopping refers to an unmanageable urge to buy something, to order, to own a thing. For the needs of this thesis, materialism is understanded as the conviction that gaining material goods is the ultimate life goal, main index of success and key to happiness. Based on the research, materialism is considered to be a significant predictor of oniomania. Aims and methodology: The main aim of this thesis was to describe the relationship between pathologic shopping and materialism. Then prevalence of pathologic shopping was further detected in the focus group which consisted solely of non-medical health care staff as well as the prevalence of age and income. The research also focused on circumstances and consequences of pathological shopping. 853 respondents participated in this correlation research based on data gained from the survey. Main results: With use of correlation analysis it was found that rising rate of materialism leads to higher tendency to shopping compulsively. 55 impulsive shoppers were identified in the research sample which makes it 6,45 % of the total number of respondents. The results showed that neither...

Le jeu vidéo est une activité de loisir particulièrement répandue auprès des adolescents. Néanmoins, pour certains, une conduite addictive peut se mettre en place, remplissant une fonction précise et nécessaire à l'équilibre du sujet. L'objectif de ce travail de thèse est d'amorcer la construction d'un modèle explicatif de ce processus addictif. L'opérationnalisation de cette recherche repose sur une méthodologie quantitative permettant de mesurer le poids et l'implication de variables psychopathologiques, cognitivo-émotionnelles et de personnalité dans la mise en place de cette conduite addictive. Le monde virtuel et l'avatar sont les deux constituants majeurs de tout jeu vidéo. Ils permettent au sujet de mettre en scène et médiatiser son Soi Emotionnel. Le processus addictif résulte d'une cristallisation de cette dynamique, ne permettant pas au sujet de se réapproprier son expérience émotionnelle. Par ailleurs, ce travail a permis de mettre en avant l'existence d'une utilisation addictive des jeux vidéo en ligne et hors ligne. Ces deux formats se différencient dans la mise en scène d'aspects du Soi Identitaire qu'ils impliquent. Pour finir, ce travail nous amène à questionner la frontière entre une utilisation régulière et addictive/pathogène des jeux vidéo. / Video games cover preferential activity of adolescents. But for some, the practice becomes an addictive behavior, playing an important role in psychological functioning of adolescents. The global aim is to establish a comprehensive model of this addictive process. This research is based on a quantitative methodology in order to assess the weight and the involvement of psychopathological, emotional and personality variables in this addictive process. Avatar and virtual world are the two essential components of any video game. They allow subject to mediatize and enact his Emotional Self. The addiction process is the result of crystallization of this dynamic which does not allow the subject to reappropriate his emotional experience. Furthermore, the research puts the light on two different types of addictive processes with on line or outline video games. These two formats differ in the enacting of aspects of the Self Identity they imply. Finally, this work leads us to question the boundary between regular and addictive / pathogen use of video games.
