Abstract

The present study aimed to use a novel method (i.e., network analysis) to examine if the Internet Gaming Disorder Scale–Short-Form (IGDS9-SF) has its unidimensional structure supported across different subgroups, including gender groups, continent groups, and age groups. Participants from five continents (n = 545 in Africa; n = 27,910 in Americas; n = 4640 in Asia; n = 88,835 in Europe; and n = 1633 in Oceania) completed the IGDS9-SF. The IGDS9-SF items showed a positively correlated network with moderate-to-high predictability (mean of R2 = 0.338, SD = 0.068). Moreover, the network analysis results suggested that the IGDS9-SF is very likely to have a one-factor model. This one-factor model was further found to be invariant across gender groups (men vs. women), continent groups (Africa, Americas, Asian, Europe, and Oceania), and age groups (minor aged under 18 years, young adults aged between 18 and 30 years, and adults aged 30 years or above).
