Abstract:
Objective:To investigate the association between subthreshold depression, psychotic like experiences (PLEs), and their interactions with non suicidal self injury (NSSI) in adolescents from Shandong, so as to provide a reference for the prevention and early intervention of NSSI in adolescents.
Methods:A random cluster sampling method was used to select a total of 6 090 adolescents aged 13-22 from two cities along the coast and inland of Shandong Province. Electronic surveys were administered using the SelfInjurious Behavior Questionnaire, Community Assessment of Psychic Experiencepositive 8 items(CAPE-P8), and the Center for Epidemiological Studies Depression Scale(CES-D). The relationship between subthreshold depression, PLEs, and their interaction with NSSI was analyzed using multivariate Logistic regression.
Results:The detection rate of NSSI among adolescents was 21.3%. The highest NSSI reporting rate (27.9%) was found in the age group of 13-15 years.The NSSI reporting rates for those detected with subthreshold depression and PLEs were 49.9% and 30.7%, respectively. Multivariate analysis indicated that individuals with subthreshold depression were 3.47 times more likely to engage in NSSI [OR(95%CI)=3.47(2.68-4.50)]. Those identified with PLEs had 5.32 times higher risk of engaging in NSSI than those without such experiences [OR(95%CI)=5.32(4.10-6.89)]. When both subthreshold depression and PLEs coexist, the risk of engaging in NSSI was 18.47 times higher than in individuals with neither condition [OR(95%CI)=18.47(14.75-23.13)] (P<0.01). The relative excess risk due to interaction (RERI), attributable proportion (AP), and synergy index (S) were 11.44, 0.61, and 2.89, respectively, indicating that the combined interaction of subthreshold depression and PLEs accounted for 61% of adolescent NSSI.
Conclusions:Subthreshold depression and psychoticlike experiences are associated NSSI in adolescents and exhibit an additive interaction. Alleviating subthreshold depression in adolescents and reducing psychotic experiences may play a positive role in preventing the occurrence of NSSI.
