 Differentiating between adolescent suicidal self-harm (SSH) and nonsuicidal self-harm (NSSH) is a significant challenge for mental health professionals, and its feasibility is controversial. The aim of the present study was to determine whether adolescent SSH can be differentiated from NSSH based on a holistic analysis of individual, psychological, sociodemographic, and environmental data without relying on intent and acquired capability for suicide and assess the findings' compatibility with the current theories of suicide. The study also sought to compare the compatibility of the result of the holistic analysis with four theories of suicide: the interpersonal theory of suicide, the three-steps theory, the integrated motivational-volitional model, and the theory of adolescent suicidality and self-destruction. This cross-sectional study analyzed data from a nationwide survey conducted from 2017 to 2019 in Norway. The study was conducted in a population-based setting. The sample included 26,904 adolescents (mean age = 15.01
  29.9 % males). The machine learning classification model reached an AUC of 77.0 % and a 70.0 % for both sensitivity and specificity in differentiating the two conditions. Exploratory factor analysis suggested eight factors for clustering the important risk and protective indicators: 1) disordered eating and future orientation, 2) sleep disturbance, 3) orientation toward affects and self, 4) risk-taking behavior, 5) peer relationships, 6) victimization, safety, and security, 7) family relationships, and 8) substance use. The results indicated that despite their high comorbidity, adolescent SSH and NSSH can be differentiated without relying on suicide-related information. These factors supported the theory of adolescent suicidality and partially supported ideation-to-action theories.
