ABSTRACT
Resumen El objetivo del presente trabajo es validar en población peruana, el Test de Dependencia de Videojuegos (TDV) (Chóliz & Marco, 2011). Los resultados obtenidos demuestran que se trata de una herramienta confiable y válida. Se encontró una sola estructura factorial, en lugar de cuatro dimensiones, como plantearon los autores del TDV. Este factor podría denominarse genéricamente: adicción a videojuegos, y podría servir como evidencia de la existencia de este trastorno, que coincidiría con el denominado 'Trastorno de Juego por Internet', que aparece en la Sección III del DSM-5. Los resultados hallados se discuten en relación a lo planteado por Chóliz y Marco (2011), en lo que se refiere a las diferencias en cuanto a sexo, edad y la estructura interna del instrumento.
Abstract The objective of this work is the validation of the Test of Dependence of Videogames (TDV) (Chóliz & Marco, 2011) in Peruvian population. The results show that it is a reliable and valid tool. We found a single factorial structure, rather than four dimensions as the authors of the TDV raised. This factor could be generically called: 'Addiction to video games', and could serve as evidence of the existence of this disorder, which would coincide with the so-called "Disorder online Game" listed in Section III of the DSM-5. The results found are discussed in relation to Chóliz & Marco (2011) in terms of differences in sex, age and the internal structure of the instrument.

The aim of the present study was to develop a valid and reliable Videogame Addiction Scale for Children (VASC). The data were derived from 780 children who completed the Videogame Addiction Scale (405 girls and 375 boys; 48.1% ranging in age from 9 to 12 years). The sample was randomly split into two different sub-samples (sample 1, n = 400; sample 2, n = 380). Sample 1 was used to perform exploratory factor analysis (EFA) to define the factorial structure of VASC. As a result of EFA, a four-factor structure comprising 21 items was obtained and explained 55% of the total variance (the four factors being "self-control," "reward/reinforcement," "problems," and "involvement"). The internal consistency reliability of VASC has found 0.89. Confirmatory factor analysis (CFA) was performed to confirm the factorial structure obtained by EFA in the remaining half of sample (n = 390). The obtained fit indices from the CFA confirmed the structure of the EFA. The 21-item VASC has good psychometric properties that can be used among Turkish schoolchildren populations.
ABSTRACT
El objetivo principal de esta investigación consistió en el análisis de la eficacia de las técnicas de control de la impulsividad para la prevención de la adicción a videojuegos añadidas a un programa de prevención previamente validado (PrevTec 3.1). Los resultados se tomaron en cuatro momentos: línea base, pre-test (primera sesión), post-test (última sesión) y seguimiento (a los tres meses). Los resultados indican que, mientras los grupos que permanecen en lista de espera no presentan cambios ni en el patrón de uso ni en la dependencia de videojuegos, aquellos en los que se aplica el programa sí que experimentan un descenso significativo. Las dos modalidades del programa de prevención son eficaces en la reducción de las variables analizadas, pero los resultados se mantienen más consistentes durante el seguimiento a quienes se entrenaron las técnicas de control de la impulsividad.
The main objective of this research has been the analysis of the effectiveness of some impulsivity control techniques to prevent videogame addiction. It has compared the results obtained with a prevention program that it had been already validated with the same program in which additional impulsiveness control techniques were added. Four periods were selected for the analysis: baseline, pre-test, post-test and follow-up. Two experimental conditions were designed: a) conventional prevention program, and b) program with impulsiveness control techniques. Results were compared with a group control (waiting list). Results indicate that, while groups that remain on waiting list do not present changes in pattern of use, those which the program was applied decrease significantly. The two modalities of prevention program were effective in the reduction of the analyzed variables, but the changes produced by the implementation of impulsive control techniques were more consistent and lasting in time.

Background and aims Multiplayer Online Battle Arena (MOBA) games have become the most popular type of video games played worldwide, superseding the playing of Massively Multiplayer Online Role-Playing Games and First-Person Shooter games. However, empirical studies focusing on the use and abuse of MOBA games are still very limited, particularly regarding impulsivity, which is an indicator of addictive states but has not yet been explored in MOBA games. In this context, the objective of the present study is to explore the associations between impulsivity and symptoms of addictive use of MOBA games in a sample of highly involved League of Legends (LoL, currently the most popular MOBA game) gamers. Methods Thirty-six LoL gamers were recruited and completed both experimental (Single Key Impulsivity Paradigm) and self-reported impulsivity assessments (s-UPPS-P Impulsive Behavior Scale, Barratt Impulsiveness Scale), in addition to an assessment of problematic video game use (Problematic Online Gaming Questionnaire). Results Results showed links between impulsivity-related constructs and signs of excessive MOBA game involvement. Findings indicated that impaired ability to postpone rewards in an experimental laboratory task was strongly related to problematic patterns of MOBA game involvement. Although less consistent, several associations were also found between self-reported impulsivity traits and signs of excessive MOBA game involvement. Conclusions Despite these results are preliminary and based upon a small (self-selected) sample, the present study highlights potential psychological factors related to the addictive use of MOBA games.
