(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.engworking paper1988-2904https://www.cambridge.org/core/journals/spanish-journal-of-psychology/article/spanish-validation-and-scoring-of-the-internet-gaming-disorder-scale-shortform-igds9sf/5157EA176E4EA9E28A345EB24741E3BDopen accessIGDS9–SF, Internet Gaming Disorder, invariance, psychometric propertiesCiencias Sociales61 Psicología
