The study investigated the temporal course of nonsuicidal self-injury (NSSI) and suicide ideation behaviour, as well as why and how NSSI confers its risk for suicide. Beginning in 2016, participants were recruited from an online eligibility screening survey administered at two universities in the United States of America (one in the south-central region and one in the midwestern region). Participants included over 400 young adults, aged 18 to 30 years, who reported engaging in NSSI within the past year. Participants were assessed at baseline and were followed up after 6 and 12 months. The study also assessed psychological and sleep-related factors through daily surveys and weekly questionnaires over a four-month period.
