Abstract OBJECTIVE: To examine the association between internet addiction and self-injurious behaviour (SIB) in adolescence. METHODS: Population-based cross-sectional survey of 1618 high school students aged 13-18 years in Guangzhou city, Guangdong Province, PR China. Deliberate SIB was measured using self-reported questionnaire; internet addiction was assessed using the Internet Addiction Test (IAT). RESULTS: 263 (16.3\%) participants reported having committed some form of SIB in the past 6 months. 73 (4.5\%) had committed SIB 6 times or more, and 157 (9.7\%) 1-5 times. The majority of respondents were classified as normal users of the internet (n = 1392, 89.2\%), with 158 (10.2\%) moderately and 10 (0.6\%) severely addicted to the internet. After adjusting for potential confounders, the odds ratio for SIB was 2.0 (95\% CI 1.1 to 3.7) for those who were classified as moderately and severely addicted to the internet when compared to the normal group. CONCLUSIONS: SIB is common in adolescence in the study population in China. Addiction to the internet is detrimental to mental health and increases the risk of self-injury among adolescents. Clinicians need to be aware of potential co-morbidities of other addictions among adolescent self-injured patients.
