Objective:
The aim of this study is to adapt and validate the Game Addiction Scale for Adolescents (GASA) to the Spanish youth population.
Design:
Cultural adaptation and validation study.
Setting:
Secondary Education centres.
Participants:
Two independent studies were conducted on a group of 466 young people with a mean age of 15.27 years (13-18, SD: 1.83) and 48.7% ♀ and on another group of 566, with a mean age of 21.24 years (19-26; SD: 1.86) 44.1% ♀.
Measurements:
Addiction to video games (GASA); Game behavior (Game habits usage questionnaire), Impulsiveness (Plutchik Impulsiveness Scale) and Group Pressure (Ad hoc questionnaire).
Results:
The Spanish version of GASA has shown good reliability and true to the original scale factor structure. As regards criterion validity, GASA scores are significantly different according to four criteria related to problem gambling: Game intensity and frequency, impulsiveness, and peer pressure.
Conclusions:
The results show that the adapted version GASA is adequate and a valid tool for assessing problematic gaming behaviour.
