| Background Addictive non-suicidal self-injury （NSSI） behaviors among adolescents have become increasingly prominent， although previous studies have identified multiple related risk factors and have examined the association between screen time and NSSI behaviors， the impact of screen time on NSSI behaviors addiction， as well as the mediating role of family dysfunction in this relationship， remain to be further clarified.Objective To investigate the mediating role of family dysfunction in the relationship between screen time and NSSI behaviors addiction among adolescent female patients with depression disorder， with the aim of providing references for reducing NSSI behaviors addiction.Methods From September 2024 to November 2025， a total of 652 adolescent female patients with depression disorder were enrolled from both outpatient and inpatient departments of Xiamen Xian-yue Hospital， all of whom met the diagnostic criteria for depressive episode （F32） or recurrent depressive disorder （F33） according to the International Classification of Diseases， tenth edition （ICD-10）. Assessments included a self-developed demographic questionnaire， screen use questionnaire， Chinese Family Assessment Instrument （C-FAI）， and Ottawa Self-injury Inventory Chinese Revised version （OSIC）. Among participants with NSSI behaviors， Spearman correlation analysis was used to examine the correlation between screen time and scale scores. Model 4 of the Process 4.1 for SPSS 26.0 was then applied to test the mediating role， and Bootstrapping procedure involving 5 000 replicates was employed to confirm the statistical significance.Results Among the 652 patients， 569 （87.27%） exhibited NSSI behaviors. Among them， 398 cases （69.95%） belonged to the addictive NSSI group， and 171 cases （30.05%） belonged to the non-addictive NSSI group. The OSIC addiction dimension score was positively correlated with screen time and C-FAI scores （rs=0.114， 0.224， P<0.01）. Family dysfunction mediated the relationship between screen time and NSSI addiction， with an indirect effect value of 0.036 （95% CI： 0.016–0.062）， accounting for 35.88% of the total effect.Conclusion Screen time may affect the NSSI behaviors addiction in adolescent female patients with depression disorder through family dysfunction. ［Funded by Joint Funds for the Innovation of Science and Technology， Fujian Province （number， 2025Y9762）］ |
