Problematic internet use (PIU) is described as internet use that hinders daily functioning and affects health and wellbeing. PIU has been a growing issue among the young adult population due to its potential association with mental health effects and addictive behaviors. Previous studies have demonstrated that compulsive internet use and gaming are associated with substance use disorder (SUD) and alcohol use disorder (AUD). This study examines the potential link between PUI and substance use outcomes in college students.
The study’s sample consisted of 417,780 US college students who completed the ACHA-NCHA II survey. Participants were asked to report diagnosis of SUD, misuse of cigarettes, e-cigarettes, alcohol, cannabis, cocaine/methamphetamine, sedatives, hallucinogens, opiates, inhalants, MDMA, and other club drugs. Students were also asked about any illicit use of prescription drugs. Behaviors indicative of PIU were assessed as well as any impact of PIU on academic performance. Data was analyzed using multivariable logistic regression models to evaluate for effects of PIU on substance misuse.
Results of the data analysis showed that 123,330 students reported PIU behaviors. Among students with PIU behaviors, 1.48% disclosed SUD diagnosis, 21.07% reported cannabis use, and 5% indicated illicit use of prescription pain killers. The multivariable logistic regression model suggested that PIU was associated with an increased risk of SUD diagnosis and misuse of sedatives, hallucinogens, opiates, inhalants, MDMA, prescription pain killers, and other club drugs. Students with PIU behaviors had lower odds of cigarette use, alcohol misuse, and illicit use of prescription sedatives than those without PIU behaviors.
Takeaway: Problematic internet use may provide predictive value when assessing substance use outcomes in college students.
