Non-suicidal self-injury (NSSI) is a major public health concern among adolescents. Further research is needed into contributors to this behavior, in particular among adolescents with psychiatric disorders. The aim of the present study was to explore the impact of life events and emotional stress on NSSI among hospitalized psychiatric adolescents.
In this cross-sectional study, 505 Chinese psychiatric adolescent inpatients 10–19 years old completed questionnaires about sociodemographic characteristics and NSSI as well as the Adolescent Self-Rating Life Events Checklist (ASLEC), the State–Trait Anxiety Inventory Form Y, and the Center for Epidemiological Studies Depression Scale. Chi-square test was used to compare the incidence of NSSI in psychiatric adolescent patients with different sociodemographic.
Most psychiatric adolescent inpatients (393, 77.8%) reported NSSI behavior. The higher risk for NSSI was observed among female (odds ratio [OR] 2.665, 95% confidence interval [CI] 1.575–4.510), younger adolescents (10–14 years; OR 2.021, 95% CI 1.258–3.245), with a suicide history (OR 2.479, 95% CI 1.549–3.967), or with depression symptom (OR 3.217, 95% CI 1.572–6.582) and those with higher scores of ASLEC (OR 1.019, 95% CI 1.010–1.029).
Our study in China is one of the first to apply to adolescent inpatients the diagnostic criteria of NSSI in the latest edition of the
