Factors Associated with Internet Addiction among Adolescents

This research examined factors associated with Internet addiction in adolescence using a population-based cross-sectional survey with self-reported questionnaires. Participants were recruited from high school students, ages 13 to 18 years, registered on the secondary school registry in Guangzhou city using a stratified random sampling technique. Internet addiction was assessed using the Internet Addiction Test (IAT). Information was also collected on demographics, health behaviors, and perception of personal condition. Depression was assessed by the Zung Self-Rating Depression Scale. The majority of respondents were classified as normal users of the Internet (n = 1,392, 89.2%), with 158 (10.2%) moderately and 10 (0.6%) severely addicted to the Internet. Results from the multivariate logistic regression analyses suggested a 50% increased odds for males to be addicted to the Internet (OR = 1.5, 95% CI = 1.1-2.2) when compared to females. Other potential risk factors included drinking behavior (OR = 1.7, 95% CI = 1.1-2.8), family dissatisfaction (OR = 2.4, 95% CI = 1.3-4.3), and experience of recent stressful events (OR = 10.0, 95% CI = 6.5-12.2). Stress-related variables were associated with Internet addiction among adolescents as they are also related to other addictions. Clinicians need to be aware of potential comorbidities of other problems such as stress and family dissatisfaction among adolescent Internet addiction patients.
