Internet Gaming Disorder and Nonmedical Prescription Drug Use: The Moderating Role of Student Status

Internet gaming disorder (IGD) and nonmedical prescription drug use (NMPDU) are prevalent, co-occurring concerns among young adults. Although prior research links problematic gaming and substance misuse, few studies have examined this relationship in non-college populations or whether student status modifies this association. This study examined the relationship between Gaming Addiction Scale (GAS) score and NMPDU among 1022 Rhode Island young adults aged 18 to 25. In the total sample, 44.6% identified as cisgender heterosexual female, 42.4% as sexual or gender minority (SGM), and 13.0% as cisgender heterosexual male. Multivariable logistic regression estimated the adjusted association between GAS scores and NMPDU, and an interaction term between GAS and student status was tested. Overall, 12.1% reported lifetime NMPDU. Higher GAS scores were associated with increased odds of NMPDU (adjusted odds ratio [AOR] = 1.05; 95% confidence interval [CI]: 1.01-1.09). Student status alone was not significantly associated with NMPDU; however, a significant interaction was observed between GAS and student status (AOR = 1.09, 95% CI: 1.01-1.18, p = 0.031). Higher GAS scores were positively associated with NMPDU, with student status strengthening this association. Findings support screening for problematic gaming, particularly among students, and integrated prevention strategies addressing both behavioral and substance-related risks.
