“…En población general Europea, las tasas ron- 2008;). Si nos referimos a población universitaria, las cifras se encuentran entre el 6% -40%, siendo difícil establecer una comparativa dadas las diferencias geográficas y fundamentalmente metodológicas encontradas (Pezoa-Jares et al, 2012;Sussman et al, 2011). Dentro de los factores de riesgo que se asocian a un UPI, destacan el sexo masculino, la edad inferior a 21 años, el domicilio fuera del hogar familiar, la baja autoestima, y la dependencia a otras conductas adictivas como es el consumo de drogas (Sánchez-Carbonell et al, 2008;Frangos et al, 2010;Muñoz-Rivas et al, 2003;Secades-Villa, 2014).…”

“…Por otra parte, estudios previos han establecido una relación entre consumo de sustancias adictivas y el UPI (Pezoa-Jares et al, 2012;Secades-Villa, 2014;Sussman et al, 2011), lo que concuerda con nuestros datos para la relación de UPI con el uso problemático de alcohol valorado por el test AUDIT. Sin embargo, no se observó asociación entre UPI y el consumo de dichas sustancias (tabaco, alcohol, drogas ilegales...) algo que es explicable por el empleo de un criterio de clasificación que no discrimina si se trata de un uso puntual o de un uso problemático, lo que provoca la inclusión del grupo de usuarios problemáticos en un grupo mucho mayor de usuarios no problemáticos generando una regresión hacia el nulo de la asociación.…”

“…Además de esto, algunos autores han encontrado una asociación con otros problemas de salud, tales como deprivación del sueño, trastornos de la conducta alimentaria, migrañas o dolores de espalda (Didia et al, 2009;Pezoa-Jares, Espinoza-Luna y Vasquez-Medina, 2012;Spada, 2014) Por otra parte, entorno al 12 % de los adultos adictos a internet presentan también problemas de dependencia o adicción al alcohol y un 5% a las drogas en general, según muestra la revisión realizada por Sussman, Lisha y Griffiths (2011). Este aspecto ha sido evidenciado en el reciente estudio de Secades-Villa et al (2014) llevado a cabo en población adolescente europea, en el que encontró una relación estadísticamente significativa entre las horas de conexión a internet y la frecuencia de consumo de alcohol, tabaco, cannabis y otras drogas ilegales.…”

The aim of this paper is to make a descriptive analysis of Problematic Internet Use in college students, evaluating the possible association with health problems and addictive behaviors, as well as gender differences in user types. A total of 2,780 students participated in the study between 2011 and 2014, 29% of them being males (age 20.8 ± 5.1 years) and 71% females (age 20.3 ± 4.4 years). The prevalence of Problematic Internet Use (PIU) assessed by the Internet Addiction Test was 6.08%. Being under 21 years of age and studying for degrees in subjects other than the health sciences were associated factors with a higher frequency of this problem, no differences by gender or type of address were found. The results show a significant association with some health problems (migraines, back pain, excess weight or obesity, insufficient rest), psychological aspects (risk of eating disorders, risk of mental disorder, depression), family problems and discrimination; with no associations with substance use (alcohol, cannabis or tobacco) being found. Concerning the time of Internet use, weekly hours were significantly higher in women than in men, both the total time as for leisure. The analysis of the profile use in problematic users revealed that males are related to aspects of entertainment such as games or shopping online and females are related to aspects of socialization, such as chats and social networks.

“…Its prevalence rates vary between 0.3% and 37.9% 3 . This variation may be justified by the difference found in the instruments that are used to measure the problem 2 , which reflect distinct theories, sampling characteristics, psychometric fragilities of the used psychometric scales.…”

Objective: To evaluate construct validity and reliability of the Portuguese (Brazil) version of Online Cognition Scale (OCS-BR). Methods: Portuguese (Brazil) versions of Online Cognition Scale (OCS), of Internet Addiction Test (IAT) and socio demographic questionnaire was applied to a sample (n = 359) of health university students. Construct validity evidence was verified through the factorial and convergent validity by Confirmatory Factor Analysis (CFA) and internal consistency and stability analysis through Cronbach's alpha and intraclass correlation coefficient (ICC) respectively. Discriminative power of items were analyzed using item-total correlation and point biserial correlation. Results: OCS-BR presented satisfactory evidence of construct validity. The instrument showed Cronbach's alpha of 0.91 and ICC of 0.91. Conclusion: Portuguese (Brazil) version of OCS shows items consistently gatherd to measure the Problematic Internet Use (PIU) construct, it is considered s stable instrument in time and with sufficient evidence of construct validity. RESUMOObjetivo: Avaliar a validade de construto e a confiabilidade da versão em português (Brasil) da Online Cognition Scale (OCS-BR). Métodos: As versões em português (Brasil) da Online Cognition Scale (OCS), da Internet Addiction Test (IAT) e um questionário sociodemográfico foram aplicados em uma amostra (n = 359) de estudantes universitários de saúde. A evidên-cia de validade de construto foi verificada por meio da validade fatorial e convergente pela Análise Fatorial Confirmatória e pela análise da consistência internal e estabilidade pelo alpha de Cronbach e coeficiente de correlação intraclasse (ICC), respectivamente. O poder discriminativo de itens foi analisado usando a correlação item-total e a correlação do ponto bisserial. Resultados: A OCS-BR apresentou evidência satisfatória de validade de construto. O instrumento apresentou o alpha de Cronbach de 0,91 e ICC de 0,91. Conclusão: A versão em Português (Brasil) de OCS mostra itens consistentemente reunidos para medir o construto Uso Problemático de Internet, sendo considerado um instrumento estável no tempo e com evidência suficiente de validade de construto.

Excessive internet use is shown to be cross sectionally associated with lower cognitive functioning and reduced volume of several brain areas. However, the effects of daily internet use on the development of verbal intelligence and brain structures have not been investigated. Here, we cross sectionally examined the effects of the frequency of internet use on regional gray/white matter volume (rGMV/rWMV) and verbal intelligence as well as their longitudinal changes after 3.0 ± 0.3 (standard deviation) years in a large sample of children recruited from the general population (mean age, 11.2 ± 3.1 years; range, 5.7-18.4 years). Although there were no significant associations in cross sectional analyses, a higher frequency of internet use was found to be associated with decrease of verbal intelligence and smaller increase in rGMV and rWMV of widespread brain areas after a few years in longitudinal analyses. These areas involve areas related to language processing, attention and executive functions, emotion, and reward. In conclusion, frequent internet use is directly or indirectly associated with decrease of verbal intelligence and development to smaller gray matter volume at later stages.
