Patients\u2019 self-harm behaviors, emotional regulation strategy capabilities, and severity of illness were assessed both prior to intervention and within 48\u202fh post-intervention. Data analysis employed one-way analysis of variance (ANOVA), Kruskal\u2013Wallis H test,\n \u03c7<\/jats:italic>\n 2<\/jats:sup>\n test, or Fisher\u2019s exact test.\n <\/jats:p>\n <\/jats:sec>\n \n Results<\/jats:title>\n \n Intervention Group B exhibited lower NSSI behavior scores than both Intervention Group A and the control group, while Intervention Group A scored lower than the control group (\n p<\/jats:italic>\n \u202f&lt;\u202f0.05). Regarding emotional regulation capacity, Intervention Group B demonstrated the highest adaptive strategy scores and the lowest maladaptive strategy scores (\n p<\/jats:italic>\n \u202f&lt;\u202f0.05). This group also recorded the lowest anxiety and depression symptom scores (\n p<\/jats:italic>\n \u202f&lt;\u202f0.05). All indicators for Intervention Group A were superior to those of the control group (\n p<\/jats:italic>\n \u202f&lt;\u202f0.05).\n <\/jats:p>\n <\/jats:sec>\n \n Conclusion<\/jats:title>\n DBT combined with STEPPS effectively reduces NSSI behaviors, improves emotion regulation, and alleviates anxiety and depression in adolescent non-suicidal self-injurious patients. And the effect of the combined intervention is better than that of the single intervention.<\/jats:p>\n <\/jats:sec>\n \n Clinical trial registration<\/jats:title>\n \n This study was registered with the Chinese Clinical Trial Registry (\n https:\/\/www.chictr.org.cn\/<\/jats:ext-link>\n ; Registration number: ChiCTR2100043855) on 4 March 2021.
