Abstract

A sample of 2144 secondary school students in China revealed a reliable checklist for Internet Gaming Disorder (IGD) symptoms.

All 9 items of the checklist were significantly and positively correlated.
The checklist showed satisfactory reliability for assessing IGD symptoms.
Confirmatory Factor Analysis confirmed a unidimensional structure for the scale.
Measurement invariance across gender and city groups was established.
Significant positive associations were found between the checklist scores and self-identified IGD, loss of control over gaming time, time spent gaming, depression, and suicidal ideation.

Simplified

This study aims to develop and validate a checklist for IGD symptoms of Chinese adolescents based on the fifth edition of the diagnostic and statistical manual of mental disorders (DISCA). We recruited 2144 secondary school students who reported that they had played Internet games in the past 12 months in two large cities of China. The 9 item of DISCA were all significantly and positively correlated and the scale reliability was satisfactory. The unidimensional structure of the scale was confirmed by Confirmatory Factor Analysis (CFA), χ/df = 246.18/27, CFI = .95, RMSEA = .06. Measurement invariance across gender and city groups was confirmed by Multiple-group CFA. Criterion validity was demonstrated by the significant positive associations between DISCA score and self-identified IGD, loss of control regarding time spent on Internet gaming, time spent on playing Internet games, depression, and suicidal ideation. DISCA is a brief, reliable, and validated assessment to measure adolescent IGD. 2
