ABSTRACT
ObjectiveTo explore the characteristics of impulsivity in adolescent depressive disorder patients with non-suicidal self-injury （NSSI） behavior， analyze the relationship between NSSI behavior and impulsivity， so as to identify patients with NSSI behavior and provide targeted intervention at early stages. MethodsA total of 53 adolescent patients with depressive disorder who were hospitalized for the first hospitalization in Shenzhen Kangning Hospital were enrolled， diagnosed using Diagnostic and Statistical Manual of Mental Disorders， fifth edition （DSM-5）. Thereafter， the adolescents were divided into NSSI group （n=30） and non-NSSI group （n=23）. Hamilton Depression Scale-17 item （HAMD-17）， Adolescents Self-Harm Scale and Barratt Impulsivity Scale （BIS-11） were used to evaluate the severity of depression， NSSI and impulsivity. ResultsCompared with the non-NSSI group， the NSSI group scored higher on HAMD-17 ［（25.50±4.10） vs. （21.43±4.64）， t=3.379， P<0.01］， motor impulsiveness of BIS-11 ［（51.67±15.95） vs. （38.70±14.90）， t=3.018， P<0.01］， cognitive impulsiveness ［（52.75±13.22） vs. （43.37±18.40）， t=2.161， P<0.05］， non-planning impulsiveness ［（68.00±15.32） vs. （50.76±21.35）， t=3.424， P<0.01］ and BIS-11 ［（57.42±11.08） vs. （44.27±14.83）， t=3.695， P<0.01］. Within NSSI group， the score of Adolescents Self-Harm Scale was positively correlated with the score of motor impulsiveness in BIS-11 （r=0.691， P<0.01）. Binary Logistic regression analysis showed that HAMD-17 score （β=0.172， OR=1.187， 95% CI： 1.007~1.400） and non-planning impulsiveness of BIS-11 （β=0.044， OR=1.045， 95% CI： 1.002~1.091） were associated with NSSI in adolescent patients with depressive disorder （P<0.05）. ConclusionThe severity of depressive symptoms and non-planning impulsiveness may be risk factors for NSSI behavior in adolescent patients with depressive disorder.
ABSTRACT
Objective:To explore the characteristics of theory of mind(TOM) ability of adolescent depressive disorder patients with non-suicidal self-injury (NSSI) behavior, and analyze the relationship between NSSI behavior and TOM, so as to identify patients with NSSI behavioral risk early and give timely intervention.Methods:A total of 54 adolescent patients with depressive disorder who were hospitalized for the first time in Shenzhen Kangning Hospital from May to October 2021 were enrolled.They were divided into NSSI group( n=31)and non-NSSI group( n=23)according to DSM-5.Hamilton anxiety rating scale-14 item (HAMA-14) and Hamilton depression rating scale-17 item(HAMD-17)were used to evaluate the severity of anxiety and depression.Hinting task, Yoni task and reading the mind in the eyes test(RMET) were used to test TOM of the two groups.Binary Logistic regression analysis in SPSS 22.0 was used to explore the influence of TOM ability on NSSI behavior of adolescents with depressive disordor. Results:Compared with patients in non-NSSI group, patients in NSSI had significantly higher scores of HAMA-14(21.48±4.92 vs 16.35±5.61, t=3.57, P<0.05) and HAMD-17(25.61±4.08 vs 21.43±4.64)( t=3.51, P<0.05). The patients in NSSI group had lower scores on the hinting task(16.10±2.84 vs 18.17±1.15, t=-3.68, P<0.05), RMET task (21.61±2.58 vs 23.61±3.07)( t=-2.59, P<0.05), and second-order cognitive TOM((18.90±3.70) vs (20.96±2.72), t=-2.27, P<0.05) and second-order affective TOM(28.84±3.93 vs 31.04±3.04)( t=-2.24, P<0.05) in Yoni task than those in non-NSSI group.Binary Logistic regression analysis showed effective TOM ( β=-0.306, OR=0.736, 95% CI= 0.552-0.982, P=0.037)and cognitive TOM ( β=-0.485, OR=0.616, 95% CI=0.396-0.957, P=0.031) were associated with non-suicidal self-injury in patients with depressive disorder. Conclusion:The increased impairment of the emotional component (decoding component) and cognitive component (reasoning component) of TOM may be risk factors for the occurrence of NSSI behavior in adolescent depressive disorder patients.
