Abstract
Since the inclusion of the Internet Gaming Disorder (IGD) in the Diagnostic and statistical manual of mental
disorders (5th ed.) (DSM-5), the Internet Gaming Disorder Scale-Short Form (IGDS9-SF), a short nine items test, has become
one of the most used standardized instruments for its psychometric evaluation. This study presents a validation and
psychometric evaluation of the Spanish version of the IGDS9-SF. A sample of 2173 videogame players between 12 and
22 years old, comprising both genders, was employed, achieved with a randomized selection process from educational
institutions in the city of Madrid. Participants completed the adapted version of the IGDS9-SF, the General Health
Questionnaire (GHQ-12) and a negative cognitions scale associated with videogame use, as well as sociodemographic
data and frequency of videogame play. A unifactorial structure with sufficient reliability and internal consistency was
found through exploratory and confirmatory analyses. In addition, the instrument was found to have good construct
validity; the scoring of the IGDS9-SF were found to show a positive association with gaming frequency, with general health
problems, and to a greater extent, with problematic cognitions with regard to videogames. Factorial invariance was found
concerning the age of participants. However, even though the factorial structure was consistent across genders, neither
metric nor scalar invariance were found; for this reason, we present a scale for the whole sample and a different one for
gender. These results suggest that this Spanish version of the IGDS9-SF is a reliable and valid instrument, useful to evaluate
the severity of IGD in Spanish students, and we provide a scoring scale for measurement purposes.
