Abstract

Internet gaming disorder (IGD) has been recognized by the American PsychiatricAssociation (APA) as a tentative disorder in the latest (fifth) revision of the Diagnostic and StatisticalManual of Mental Disorders (DSM-5). However, psychometric evaluation of the nine IGD criteriaremains necessary to further enhance its assessment. Therefore, the objective of this study was toevaluate the psychometric properties of the Spanish version of the Internet Gaming Disorder ScaleShort Form (IGDS9-SF). The internal structure, internal consistency, temporal stability, andrelationships with other variables were assessed. Furthermore, a polytomous item response theory(IRT) approach was used to evaluate the performance of each item and the test as a whole. A sampleof 388 online gamers (53.61% women, mean age 25.45 years, standard deviation (SD) = 9.62) wasrecruited for this study. Similar to previous research, the results supported a one-factor structurefor the IGDS9-SF, adequate internal consistency and temporal stability of scores, goodness of fit ofthe items to the graded response model (GRM), and more precise scores at high trait levels to assessIGD in Spanish populations. These findings corroborate the suitability of the Spanish IGDS9-SF forclinical assessment and research within Spanish-speaking populations.
