RT Generic T1 Spanish Validation and Scoring of the Internet Gaming Disorder Scale - Short-Form (IGDS9-SF) A1 Fernández Arias, Ignacio Gabino A1 Sánchez Iglesias, Iván A1 Bernaldo De Quirós Aragón, Mónica A1 Labrador Encinas, Francisco Javier A1 Estupiñá Puig, Francisco José A1 Labrador Méndez, Marta Isabel A1 Fernández Arias, Ignacio Gabino AB Since the inclusion of the Internet Gaming Disorder (IGD) in the Diagnostic and statistical manual of mentaldisorders (5th ed.) (DSM-5), the Internet Gaming Disorder Scale-Short Form (IGDS9-SF), a short nine items test, has becomeone of the most used standardized instruments for its psychometric evaluation. This study presents a validation andpsychometric evaluation of the Spanish version of the IGDS9-SF. A sample of 2173 videogame players between 12 and22 years old, comprising both genders, was employed, achieved with a randomized selection process from educationalinstitutions in the city of Madrid. Participants completed the adapted version of the IGDS9-SF, the General HealthQuestionnaire (GHQ-12) and a negative cognitions scale associated with videogame use, as well as sociodemographicdata and frequency of videogame play. A unifactorial structure with sufficient reliability and internal consistency wasfound through exploratory and confirmatory analyses. In addition, the instrument was found to have good constructvalidity; the scoring of the IGDS9-SF were found to show a positive association with gaming frequency, with general healthproblems, and to a greater extent, with problematic cognitions with regard to videogames. Factorial invariance was foundconcerning the age of participants. However, even though the factorial structure was consistent across genders, neithermetric nor scalar invariance were found; for this reason, we present a scale for the whole sample and a different one forgender. These results suggest that this Spanish version of the IGDS9-SF is a reliable and valid instrument, useful to evaluatethe severity of IGD in Spanish students, and we provide a scoring scale for measurement purposes.
