The Association Between Non-Suicidal Self-Injury and Suicide Attempts in Adolescents:the Moderating Role of Anxiety and Depression
Objective:To explore the relationship between non-suicidal self-injury(NSSI)and suicide attempts,and the moderating effect of anxiety and depression.Methods:The non-suicidal self-injury,anxiety,and depressive self-rat-ing scales and related clinical interview tools were used to evaluate and diagnose adolescent patients from the outpatient de-partment of clinical psychology in general hospitals.A total of 277 adolescent patients who had non-suicidal self-injury for more than 1 day in the past year were collected,including 110 with suicide attempt and 167 without suicide attempt.Re-sults:The number of NSSI methods(OR=0.627,P=0.037),the behaviors of self-hitting(OR=4.017,P=0.010)and inserting objects under skin or nails(OR=4.892,P=0.008)were significantly associated with suicide attempts.The interaction be-tween the frequency of NSSI and medium-high level of anxiety had a significant predictive effect on suicide attempts(B=0.081,P=0.011).There was a significant interaction between the ways of hitting oneself and the medium-high level of anxi-ety(B=0.085,P=0.030)and the medium-high level of depression(B=0.090,P=0.009).Conclusion:Specific forms of self-injury,such as hitting oneself and inserting objects under the skin,have direct impact on suicide attempts,while anxiety and depression have certain moderating effects on the relationship between the frequency of NSSI,or hitting oneself and sui-cide attempts.
