Introduction. Social networks are used by around 3,600 million people, they facilitate communication and promote human ties; but its inappropriate use could cause problems and extreme addiction. Objective: Relate addiction to social networks and emotional intelligence. Method: Correlational study, 279 students of technical-superior level participated; The Social Media Addiction Questionnaire (ARS) and the Wong-Law Emotional Intelligence Scale (EI) were administered. Results: Obsession (ARS) negatively correlates with Use of one’s own emotions and Regulation of emotions; likewise, Lack of control and Excessive use (ARS) with the dimensions Valuation of one’s own emotions, Use of one’s own emotions and Regulation of emotions; but, no factor of the ARS correlates with Valuation of the Emotions of the others; Likewise, men and women do not differ in the ARS, those who have more hours of connection are more likely to show higher scores in network addiction; and, in terms of emotional intelligence, women value the emotions of others more. Conclusions: Addiction to social networks and emotional intelligence are negatively related in almost all their dimensions, but it is an association of low magnitudes. / Introducción. Las redes sociales son usadas por alrededor de 3,600 millones de personas, ellas facilitan la comunicación y favorecen los vínculos humanos; pero su uso inadecuado, podría ocasionar problemas y en el extremo adicción. Objetivo: Relacionar adicción a redes sociales e inteligencia emocional. Método: Estudio correlacional, participaron 279 estudiantes de nivel técnico-superior; se administraron el Cuestionario de Adicción a Redes Sociales (ARS) y la Escala de Inteligencia Emocional (IE) de Wong-Law. Resultados: Obsesión (ARS) correlaciona negativamente con Uso de las propias emociones y Regulación de las emociones; igualmente, Falta de control y Uso excesivo (ARS) con las dimensiones Valoración de las propias emociones, Uso de las propias emociones y Regulación de las emociones; pero, ningún factor del ARS correlaciona con Valoración de las Emociones de los demás; asimismo, hombres y mujeres no se diferencian en la ARS, los que tienen más horas de conexión son más propensos a mostrar puntajes más altos en adicción a redes; y, en cuanto a la inteligencia emocional, las mujeres valoran más las emociones de los demás. Conclusiones: La adicción a las redes sociales y la inteligencia emocional se relacionan negativamente en casi todas sus dimensiones, pero es una asociación de baja magnitud.

Le comportement envers une activité physique (AP) peut être compris sur un continuum où les individus inactifs et les individus qui pratiquent de façon excessive représentent les deux extrémités. Au milieu de ce continuum se trouvent les individus qui pratiquent de façon modérée et régulière. Ce sont ces derniers qui semblent bénéficier le plus de la pratique d’une AP (Canning et al., 2014; Kern et al., 2013; Warburton et al., 2006; Spirduso, 1995) (Spirduso, 1995). Cette thèse a pour but de comprendre les comportements dites ‘à risque pour la santé’ par rapport à la pratique d’AP, notamment l’inactivité physique et la pratique problématique d’exercice physique (PPEP). Cette thèse s’articule donc en deux parties. La première partie ‘‘Perspectives théoriques’’ a pour but la présentation d’une recherche adaptée afin de fournir une compréhension complète des comportements vis à vis la pratique d’AP et plus particulièrement l’inactivité physique et la PPEP. Cette partie vise également à faire un état de lieu de leurs méthodes d’évaluation, leurs causes et conséquences, ainsi que leurs préventions et traitements. La deuxième partie ‘‘Perspectives empiriques’’ qui sera elle même divisée en deux sous sections, sera consacrée aux différents articles (publiés ou en cours) englobant l’inactivité physique chez les étudiants universitaires et la PPEP: le but de cette dissertation est donc double et s’articule autour de sept articles. 1/Pour comprendre le problème d’inactivité physique à travers: (a) Une revue systématique de la prévalence globale de l’inactivité physique au sein des étudiants universitaires; (b) Une étude croisée effectuée au sein des communautés estudiantines françaises et indiennes; (c) Une étude exploratoire afin de tracer le profil des étudiants inactifs en Inde. 2/ Afin de mieux cerner le phénomène de la PPEP grâce à:(a) La validation d’un modèle hiérarchique définissant la PPEP; (b) L’étude du cas clinique d’un homme de cinquante ans mettant en lumière le développement et les motivations vis à vis la PPEP;(c) Une etude exploratoire sur les liens entre la PPEP et les traits d’impulsivité; (d) Cette étude vise à reproduire le modèle de Cook & Hausenblas (2008) qui postule que la PPEP joue un rôle de médiateur entre l’exercice physique et les troubles du comportements alimentaires (TCA). / Behavior towards physical activity (PA) can be investigated on a continuum with physical inactivity on one end and excessive exercise leading to the dangers of doping and/or problematic practice of physical exercise (PPPE), on the other. The aim of the current dissertation is to further clarify the concepts of physical inactivity as well as PPPE, in order to promote the adoption of regular and moderate PA while taking into account the negative consequences of excessive exercising. This dissertation is divided into two parts. The purpose of Part I – ‘Theoretical Perspectives’ is to present pertinent research and provide a general understanding of physical inactivity and PPPE. Part II – ‘Empirical Perspectives’, consists of the various research papers encompassing the two phenomena. Thus, the aim of this dissertation is twofold and is achieved through seven papers: 1/To understand the epidemic of physical inactivity through (a) a systematic review of prevalence of physical inactivity in college students globally on studies done between 2002 and 2015, (b) a cross sectional study done on a cohort of French and Indian university students and (c) an analysis of the psychological correlates of physical inactivity amongst Indian university students. 2/ To understand the phenomenon of PPPE through (a) the validation of an hierarchical model explaining PPPE, (b) a clinical case study of a 50 year old man throwing light upon the development and motivations towards PPPE, and (c) the possible links between traits of impulsivity and PPPE. This section also presents a fourth working article which (d) aims to replicate the mediation model of exercise, PPPE and eating pathology validated by Cook & Hausenblas (2008) along with the motivation to control weight.

Rationale Although there is evidence that impaired executive functioning plays a role in addictive behavior, the longitudinal relationship between the two remains relatively unknown. Objectives In a prospective-longitudinal community study, we tested the hypothesis that lower executive functioning is associated with more addictive behavior at one point in time and over time. Methods Three hundred and thirty-eight individuals (19–27 years, 59% female) from a random community sample were recruited into three groups: addictive disorders related to substances (n = 100) or to behaviors (n = 118), or healthy controls (n = 120). At baseline, participants completed nine executive function tasks from which a latent variable of general executive functioning (GEF) was derived. Addictive behavior (i.e., quantity and frequency of use, and number of DSM-5 criteria met) were assessed using standardized clinical interviews at baseline and three annual follow-ups. The trajectories of addictive behaviors were examined using latent growth curve modeling. Results At baseline, we found weak to no evidence of an associations between GEF and addictive behavior. We found evidence for an association between a lower GEF at baseline and a higher increase in the quantity of use and a smaller decrease in frequency of use over time, but no evidence for an association with an increase in the number of DSM-5 criteria met. Conclusions Lower EFs appear to lead to a continuing loss of control over use, whereas addictive disorders may develop secondarily after a long period of risky use. Previous etiological models assuming lower EF as a direct vulnerability factor for addictive disorders need to be refined.
