BACKGROUND: Suicide is a critical public health issue in adolescents worldwide. Internet addiction may play a role in the increased rate of suicide attempts in this population. However, few studies have explored the relationship between pathological internet use and suicide attempts among adolescents.
OBJECTIVE: This study aimed to conduct a prospective cohort study to examine whether higher severity of pathological internet use was associated with an increased risk of suicide attempts among Chinese adolescents.
METHODS: A total of 782 adolescents were recruited from a middle school from November 2020 to December 2020 and followed up for 6 months. An online self-reported questionnaire was used to collect the participants' demographic data and assess their mental health. The Depression, Anxiety, and Stress Scale-21 items (DASS-21) was used to evaluate depression, anxiety, and stress. The Chen Internet Addiction Scale-Revised (CIAS-R) was used to assess the symptoms and severity of pathological internet use. χ2 test and ANOVA were used for intergroup comparison, and logistic regression analysis was used to examine the relationship between the severity of pathological internet use and suicide attempts. We also used a restricted cubic splines model to investigate the pattern of the association.
RESULTS: The participants had an average age of 12.59 (SD 0.64) years, with the majority being of Han ethnicity (743/782, 95.01%) and more than half being male (426/782, 54.48%). Most participants had no previous history of depression (541/782, 69.18%), anxiety (415/782, 53.07%), or stress (618/782, 79.03%). The rate of newly reported suicide attempts was 4.6% (36/782). A significant positive association was observed between internet addiction and suicide attempts (odds ratio 3.88, 95% CI 1.70-8.82), which remained significant after adjusting for age, sex, ethnicity, anxiety, depression, and stress (odds ratio 2.65, 95% CI 1.07-6.55). In addition, this association exhibited a linear pattern in the restricted cubic spline regression model.
CONCLUSIONS: This study suggested that internet addiction, rather than internet overuse, was associated with a higher likelihood of suicide attempts, which highlighted the importance of addressing internet addiction symptoms among Chinese adolescents for suicide prevention.
