Overview

Item response theory reveals strong diagnostic properties for DSM-5 criteria in Chinese adolescents, suggesting revision for escape criterion.

Key Points

  • The aim was to evaluate the psychometric properties of DSM-5 criteria for Internet Gaming Disorder using item response theory.
  • Administered four DSM-5-based scales to 1,530 Chinese adolescents and young adults.
  • Used item response theory (IRT) models to assess psychometric properties.
  • Evaluated differential item functioning related to sex and between adolescents and adults.
  • All nine DSM-5 criteria showed high discrimination and substantial diagnostic information.
  • Withdrawal had the highest item information, while escape showed the lowest performance among the criteria.
  • No evidence of differential item functioning related to sex or age was found across scale items.
