Area of Science:

  • Psychology
  • Clinical Psychology
  • Behavioral Science

Background:

  • Internet addiction and problematic gaming are growing public health concerns.
  • Accurate screening tools are needed to identify individuals at risk for game overuse.

Purpose of the Study:

  • To develop and validate the Game Overuse Screening Questionnaire (GOS-Q).
  • To assess the reliability, validity, and diagnostic ability of the GOS-Q.

Main Methods:

  • Developed preliminary items, refined to 30 questions based on expert review.
  • Administered GOS-Q to 150 participants from internet addiction centers.
  • Assessed concurrent validity using established internet addiction scales and exploratory factor analysis for construct validity.

Main Results:

  • GOS-Q demonstrated favorable internal consistency (α=0.96) and item-total correlations (r=0.47-0.82).
  • Test-retest reliability was moderate (r=0.74), with superior concurrent validity (highest correlation with Y-Scale, r=0.77).
  • A cut-off score of 38.5 showed high diagnostic accuracy (AUC=0.945, sensitivity=0.87, specificity=0.88).

Conclusions:

  • The GOS-Q is a reliable and valid screening tool for identifying game overuse.
  • The questionnaire shows significant potential for use in clinical and research settings.
  • Effective screening can aid in early intervention for problematic gaming behaviors.
