Methods: Cross-sectional data was collected from 247 youth (M age = 16.0, SD = 1.2) in a face-to-face setting using Qualtrics survey software to record the responses. Of the 247 youth, 63.6% were girls, 35.6% were boys. Most of the sample (69.2%) were African American, and 27.1% were Latino/a. Youths’ IGD, problematic Internet use, substance abuse, and mental distress symptoms were assessed using standardized measures. Youth reported sociodemographic information. Confirmatory factory analysis (CFA) was used to examine the validity of the IGD-20 based on the factor structure suggested by empirical evidence. Bivariate analyses were used to examine the differences in characteristics of gaming behaviors and psychosocial correlates between youths with IGD and non-IGD.
Results: The CFA indicated a reasonable fit of a 6-factor structure of the IGD-20 (i.e., salience, tolerance, withdrawal, mood alteration, negative consequences, lack of control over gaming behaviors) in this sample [χ2 (139) = 265.59, p < .001, RMSEA = .067, CFI = .94]. Approximately 2.4% of the sample met the suggested cut-off score for IGD (IGD-20 > 71) Bivariate test revealed that significantly more youths with IGD reported playing video games on the Internet than their non-IGD peers (p < .001). Moreover, youths with IGD evidenced significantly higher levels of problematic Internet use behaviors (p < .001), substance abuse problems (p < .001), and sleep problems (p < .05) compared to those who did not have IGD. IGD was significantly positively correlated with problem Internet use (r = .28, p < .001). No significant difference was observed in IGD between boys and girls (p > .05).
Conclusion and Implications: The CFA demonstrated that the IGD-20 may be used as a valid measure for assessing IGD among racial/ethnic minority youth, specifically among African American and Latino/a youth. Despite the relative low prevalence rate of IGD in this sample, findings suggest that youths with IGD have significantly more severe substance abuse, sleep problems, and problematic Internet use behaviors compared to their non-IGD counterparts. Accordingly, clinicians and service providers may need to screen and assess for IGD among youths at risk for other behavioral problems. Implications to research and clinical practice will be discussed.
