Kiekens G, et al. - Researchers prospectively examined the incidence of non-suicidal self-injury (NSSI) in college. Data on NSSI, sociodemographics, traumatic experiences, stressful events, perceived social support, and mental disorders were collected from students using data from the Leuven College Surveys (n=4,565). In all, 2,163 baseline responders provided data at a 2-year annual follow-up assessment (63.2% conditional response rate). According to findings, 1-year incidence of first onset NSSI was 10.3% and 6.0% in years 1 and 2, respectively, with a total of 8.6% reporting sporadic NSSI (1–4 times yearly) and 7.0% reporting repetitive NSSI (≥ 5 times yearly) during the first 2 years of college. These findings suggested a high risk for the onset of NSSI in the college period. Young adults at high risk for self-injury could be identified and offered timely intervention using an individualized web-based screening approach.
