NSSI behavior is an independent risk factor for suicide， which not only poses a serious threat to the mental health of children and adolescents， but also brings a great burden on families and society. This paper focuses on the epidemiology， etiology， relationship with other psychiatric disorders， and treatment of NSSI behaviors in children and adolescents.

Establishment and verification of a diagnostic prediction model for non-suicidal self-injury behaviors in adolescents with depressive disorder / 四川精神卫生

ObjectiveTo establish a diagnostic prediction model for non-suicidal self-injury （NSSI） behaviors in adolescents with depressive disorder， in order to provide references for early identification of NSSI behaviors in them. MethodsRetrospective analysis was performed on the clinical data of adolescents with depressive disorder （n=366） who were admitted to the Pediatric Department of Shenzhen Kangning Hospital from January 1 to December 31， 2021. According to the Diagnostic criteria of Diagnostic and Statistical Manual of Mental Disorders， fifth edition （DSM-5） diagnostic criteria for NSSI， the patients were divided into comorbid NSSI group （n=289） and non-NSSI group （n=77）. The selected adolescents were randomly divided into a training set （n=258） and a verification set （n=108） in a 7∶3 ratio. Logistic regression analysis was used to screen the independent risk factors for NSSI behaviors in adolescents with depressive disorder， which served as the basis for prediction model. Finally， the receiver operating characteristic （ROC） curve was established and the area under curve （AUC） was calculated to evaluate the discrimination in the training set and validation set. Calibration curve was applied to evaluate the calibration degree of the model. The Homser-Lemeshow （HL） test was conducted to evaluate the goodness of fit of the model. And decision curve analysis （DCA） was performed to evaluate the clinical benefit of the model. ResultsGender （β=1.734， OR=5.561， 95% CI： 2.678~11.964）， education level （β=0.864， OR=2.737， 95% CI： 1.174~4.795）， history of suicide attempts （β=0.932， OR=2.539， 95% CI： 1.253~5.144）， being an only child （β=0.745， OR=2.106， 95% CI： 1.029~4.311） and depression severity （β=0.056， OR=1.058， 95% CI： 1.025~1.092） were independent risk factors related to NSSI behaviors in adolescents with depressive disorder （P<0.05 or 0.01）. The AUC was 0.808 （95% CI： 0.746~0.870） in the training set， and was 0.722 （95% CI： 0.581~0.864） in the validation set. The prediction model showed good calibration with the HL test （P=0.561）. ConclusionGender， education level， suicide attempt history， being an only child and depression severity are independent risk factors for NSSI behaviors in adolescents with depressive disorder， furthermore， the diagnostic clinical prediction model constructed using above factors for NSSI behaviors in adolescents with depressive disorder has displayed good sensitivity and specificity.

Advances in the electrophysiological research on neurocognitive function in adolescents with non-suicidal self-injury / 中国当代儿科杂志

Non-suicidal self-injury (NSSI) is becoming increasingly common in adolescents and seriously affects their physical and mental health, and it is also a major risk factor for suicide among adolescents. NSSI has now become a public health issue of general concern; however, the identification of cognitive dysfunction in NSSI is still based on neuropsychological cognitive assessment and subjective questionnaire assessment, with a lack of objective evaluation indicators. As a method for studying the cognitive neural mechanism of NSSI, electroencephalography is a reliable tool for finding objective biomarkers of NSSI. This article reviews the recent research on electrophysiology associated with cognitive dysfunction in adolescents with NSSI.

Analysis of characteristics of non-suicidal self-injury in 120 adolescents / 上海预防医学

ObjectiveTo explore the characteristics of adolescent non-suicidal self-injury （NSSI） behavior， and to enable clinicians to further understand adolescents with NSSI behavior， so as to make better clinical diagnosis and intervention. MethodsFrom July 2022 to June 2023， 120 adolescent patients with NSSI behavior were selected from the outpatient department of our hospital by convenience sampling， and the general demographic data were collected by self-made general situation questionnaire. The characteristics and motivation of NSSI among adolescents with NSSI were analyzed by using the NSSI questionnaire and Ottawa self-injury inventory （OSI）. ResultsThe average age of the first NSSI in the adolescents was 12.90±1.233， and the most common was 13 years old. The most common site of NSSI was the lower arm or wrist （58.33%）， followed by the hand （27.5%）. The most commonly used NSSI was "intentionally cutting oneself" （68.33%）； The most common motivation for NSSI is emotional regulation. ConclusionThere are significant differences in gender among adolescents with NSSI behavior. The age of first NSSI is concentrated， and the highest incidence is in the 11‒14 years old. The common way of self-injury is cutting. NSSI is usually associated with the intention to relieve suffering and is characterized by high frequency， using variety of methods， and low mortality. Adolescents with NSSI often choose to implement NSSI with emotion regulation as the main function， including external emotion regulation and internal emotion regulation.

Psychological experiences in adolescents with non-suicidal self-injury behavior： a qualitative Meta-synthesis / 四川精神卫生

BackgroundNon-suicidal self-injury （NSSI） is a serious global public health issue and an important risk factor for suicide attempts and completed suicide. The incidence of NSSI among adolescents in China is 27.4%. Therefore， it is critical to address NSSI and prevent its progression into more severe mental health conditions. ObjectiveTo systematically evaluate the psychological experiences and needs of adolescents with NSSI behavior， so as to provide references for formulating targeted intervention strategies for this demographic. MethodsA computer search was conducted across a total of eleven databases， including Cochrane Library， Embase， PubMed， PsycINFO， Web of Science， CINAHL， Medline， CNKI， Wanfang， VIP and CBM， to gather qualitative research on the psychological experiences and needs of adolescents with NSSI behavior. The search extended from the establishment of these databases up to March， 2023. The Australian Joanna Briggs Institute （JBI） qualitative research quality evaluation tools were used to evaluate the included literature， and a Meta-synthesis method was used to integrate the results. ResultsA total of 11 studies were included， yielding 46 research findings. Similar findings were consolidated into 10 new categories， ultimately resulting in 5 synthesized outcomes， including interpersonal conflict， academic pressure and self-reflective struggles， self-injurious behaviors intertwined with inner emotions， the power of love to overcome helplessness， and adjustment and seeking positive coping strategies. ConclusionAdolescents often have experienced negative life events before NSSI behaviors， with notable conflicts in interpersonal relationships， academic pressures and family education. Following NSSI behavior， they undergo various psychological experiences， such as transient feelings of relief， dependence and guilt. In addition， they crave guidance and assistance from professionals to cope with negative emotions.［Funded by Social Psychological Service and Crisis Intervention in 2022 （number， LZXL-202213）］

Relationship between depressive mood and non-suicidal self-injury in middle school students： the mediating role of impulsivity / 四川精神卫生

BackgroundNon-suicidal self-injury （NSSI） behavior poses a significant risk to the psychosomatic health of middle school students. However， the intrinsic mechanisms underlying the risk factors associated with NSSI behavior remain unclear. ObjectiveTo explore the relationship and underlying mechanism between depressive mood， impulsivity， and NSSI behavior in middle school students， and provide valuable insights for the prevention and intervention of NSSI behavior in this population. MethodsIn March 2021， 1 161 middle school students were recruited by cluster random sampling. They were assessed using Adolescent Non-Suicidal Self-Injury Assessment Questionnaire （ANSAQ）， Center for Epidemiologic Studies Depression Scale （CES-D）， and Barratt Impulsivity Scale （BIS-II）. Spearman's correlation analysis was used to examine the correlation between depressive mood， impulsivity and NSSI behavior in middle school students. Moreover， the Process mediation effect analysis was adopted to test the mediating role of impulsivity between depressive mood and NSSI behavior. ResultsTotal of 122 people（10.51%） with NSSI behavior were detected. CES-D score was positively correlated with the total score of BIS-II and scores of all dimensions （r=0.340~0.556， P<0.01）， and also were positively correlated with the total score of ANSAQ and scores of all dimensions （r=0.437~0.540， P<0.01）. Additionally， the total score and dimension scores of BIS-II were positively correlated with the total score and dimension scores of ANSAQ （r=0.157~0.437， P<0.01）. Impulsivity played a partial mediating role between depressive mood and NSSI behavior ［indirect effect=0.035 （95% CI： 0.004~0.067， P<0.01）， indirect effect accounted for 5.81% of the total effect］. ConclusionDepressive mood in middle school students has both a direct and indirect influence on NSSI behavior， partially mediated by impulsivity. Consequently， impulsivity plays a partial mediating role between depressive mood and NSSI behavior.［Funded by Humanities and Social Sciences Research Science Institute of Chongqing Municipal Education Commission （number， 23KSZ017）］

Effect of knowledge of a friend's non-suicidal self-injury behavior on self injury and suicide behaviors of adolescents / 中华行为医学与脑科学杂志

Objective:To explore the relationship between knowledge of a friend's non-suicidal self-injury (NSSI) behavior and self injury and suicide behaviors of adolescents.Methods:From January 2020 to January 2021, totally 1 683 students from a middle school in Xiamen were randomly selected by cluster sampling.The suicide items of the self-injurious thoughts and behaviors interview(SITBT) were used to assess whether students were aware of their friends' self injurious history and their self injurious behaviors.The suicide items of the mini international neuropsychiatric interview for children and adolescents (MINI-KID) were used to assess students' suicide ideation and behavior.The data were statistically analyzed by SPSS 21.0 software.Logistic regression model was used to analyze the relationship between knowledge of a friend's NSSI and adolescents' own self-reported NSSI and suicidal behaviors.Results:A total of 1 683 junior and senior high school students completed the survey, including 412 (24.4%) who knew their friend's NSSI history and 1 271 (75.6%) who did not know their friend's NSSI history.There were statistically significant differences between the adolescents known and unknown friends' NSSI histories in terms of age, gender, whether they were left-behind children, mental disorders, their own NSSI, suicide attempts, and suicidal ideation (all P<0.05). Knowledge of a friend's NSSI behavior had positive predictive effect on adolescents' own NSSI behavior ( β=0.558, OR=2.01, 95% CI=1.58-3.88), suicidal ideation( β=0.238, OR=3.03, 95% CI=2.08-5.55), and suicide attempts ( β=0.233, OR=2.88, 95% CI=1.55-5.45) (all P<0.05). Conclusion:Knowledge of a friend's NSSI behavior may have an impact on adolescents' own self-injury and suicidal behavior.

Childhood trauma and non-suicidal self-injury in college students: chain mediating effects of rejection sensitivity and experiential avoidance / 中华行为医学与脑科学杂志

Objective:To explore the effect of childhood trauma on non-suicidal self-injury and the chain mediating effect of rejection sensitivity and experiential avoidance.Methods:From June 2021 to April 2022, totally 1 130 college students were investigated with childhood trauma questionnaire-short form(CTQ-SF), the tendency to expect rejection scale, acceptance and action questionnaire-2nd edition(AAQ-Ⅱ) and Ottwa self-injury inventory(OSI). SPSS 25.0 and Mplus 8.0 software were used for descriptive analysis, Spearman correlation analysis, structural equation model construction and Bootstrap mediation effect test.Results:Correlation analysis showed that childhood trauma (34.64±8.25), rejection sensitivity (58.02±9.54), experiential avoidance (23.90±7.96) and non-suicidal self-injury (0(0, 1)) were all significantly positively correlated with each other( r=0.163-0.532, all P<0.01). Structural equation model showed that empirical avoidance played a partial mediating effect between childhood trauma and non-suicidal self-injury in college students, with an effect size of 0.045(95% CI=0.013-0.084). Rejection sensitivity and experiential avoidance played a chain mediating effect between childhood trauma and non-suicidal self-injury in college students, with an effect size of 0.017(95% CI=0.005-0.035). Conclusion:Childhood trauma can directly predict non-suicidal self-injury in college students, and it can also indirectly predict non-suicidal self-injury through the partial mediation effect of experiential avoidance and the chain mediation effect of rejection sensitivity and experiential avoidance.

Effect of theory of mind on non-suicidal self-injury behavior in adolescent patients with depressive disorder for the first hospitalization / 中华行为医学与脑科学杂志

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.

Association between non-suicidal self-injury behavior and impulsivity in adolescent patients with depressive disorder in the first hospitalization / 四川精神卫生

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.

Subgroup analysis of NSSI behavior in adolescents with depression implied that the prevalence rate was 36% （95% CI： 22%~50%） in female adolescents， which was higher than 18% （95% CI： 12%~24%） in male adolescents. The prevalence rate of NSSI behavior was 57% （95% CI： 38%~77%） in depression adolescents with suicidal ideation， which was higher than 4% （95% CI： 0~8%） in those without suicidal ideation. The prevalence rate of NSSI behavior was 54% （95% CI： 41%~67%） in depression adolescents diagnosed with Diagnostic and Statistical Manual of Mental Disorders， fifth edition （DSM-5）， which was higher than 46% （95% CI： 40%~51%） in those diagnosed with the International Classification of Diseases， tenth edition （ICD-10）. The prevalence rate of NSSI behavior was 52% （95% CI： 41%~63%） in depression adolescents in the literatures with quality score of 7， which was close to 50% （95% CI： 44%~55%） in depression adolescents in the literatures with quality score of 6. The comparison of above subgroups all had statistical differences （P<0.05 or 0.01）. ConclusionChinese adolescents with depression suffer a high prevalence rate of NSSI behavior， with higher prevalence in females than in males， and in those with suicidal ideation than in those without suicidal ideation.

#automutilação: a expressão simbólica da autolesão não suicida / #automutilação: a expressão simbólica da autolesão não suicida / #automutilación: la expresión simbólica de la autolesión no suicida

A autolesão não suicida (ALNS) é um fenômeno de relevância crescente com altas taxas de prevalência em adolescentes e jovens adultos. Como método, foi realizada etnografia virtual em comunidade de autolesão no Facebook de modo a ampliar a compreensão dos aspectos simbólicos relacionados à prática. Em fevereiro de 2021, 133 publicações foram coletadas e divididas em três categorias de análise: autolesão, sofrimento e religião. A autolesão é compreendida como similar ao comportamento compulsivo por meio do qual praticantes buscam uma experiência de transcendência ainda que às custas de dor. Assemelha-se a uma dependência comportamental. O sofrimento descrito aponta processos depressivos e se caracteriza por solidão, dificuldade de expressão de sentimentos e necessidade de manutenção de uma persona funcional no cotidiano. Assim, a comunidade emerge como meio de expressão dos aspectos relegados à sombra no mundo offline.

Non-suicidal self-injury (NSSI) is a phenomenon of increasing relevance, with high prevalence rates in adolescents and young adults. NSSI is one of the main risk factors for future. The method of virtual ethnography was carried out in a self-injury community on Facebook in order to broaden the understanding of the symbolic aspects related to the practice. In February 2021, 133 publications were collected and divided into three categories of analysis: self-injury, suffering and religion. Self-injury was understood as a compulsive behavior through which practitioners seek an experience of transcendence at the expense of pain. It resembles an addict behavior. The suffering described refers to depressive processes and is characterized by loneliness, difficulty in expressing feelings and the need to maintain a functional persona in everyday life. Therefore, the group emerges as a means of expressing aspects relegated to the shadows in the offline world.

A chain mediating model of rumination and depression between non-suicidal self-injury and suicidal ideation in adolescents with depressive disorder / 中华行为医学与脑科学杂志

Objective:To explore the effects of non-suicidal self-injury on suicidal ideation in adolescents with depressive disorder, and the mediating role of rumination and depression between them.Methods:A sample of 397 depressive disorder adolescents were recruited to complete the adolescent non-suicidal self-injury behaviour questionnaire, ruminative responses scale (RRS), self-rating depression scale (SDS), and Beck scale for suicide ideation-Chinese version(BSI-CV). All data processing and analysis were performed using SPSS 23.0.The mediating effect was tested by correlation analysis and Bootstrap analysis.Results:The non-suicidal self-injury score was (29.192±11.281), the rumination score was (65.036±12.284), the depression score was (75.770±11.278), and the suicidal ideation score was (40.681±11.626). Non-suicidal self-injury was significantly and positively correlated with suicidal ideation( r=0.403, P<0.01), rumination and depression( r=0.332, 0.470, both P<0.01). Rumination was significantly and positively correlated with depression and suicidal ideation( r=0.549, 0.181, both P<0.05). Depression was significantly and positively correlated with suicidal ideation( r=0.313, P<0.01). The direct effect value of non-suicidal self-injury on suicidal ideation was 0.341(95% CI=0.238-0.444), the indirect effect of non-suicidal self-injury on suicidal ideation through two pathways, the separate mediating effect value of depression was 0.057(95% CI=0.077-0.114), and the chain mediating effect value of rumination and depression was 0.026(95% CI=0.004-0.057). Conclusion:Non-suicidal self-injury can directly affect suicidal ideation of depressive disorder adolescents and indirectly through rumination and depression.

The relationship between non-suicidal self-injury and implicit attitude / 中华行为医学与脑科学杂志

Non-suicidal self-injury(NSSI) is defined as deliberate " destruction to body issue without conscious suicidal intent" and which is not culturally and socially sanctioned.The evaluation of NSSI mainly includes explicit measurement and implicit measurement.In recent years, implicit measurement has received wide attention from scholars, among which the implicit association task(IAT), as a tool to measure the relative attitude towards objects in individuals' implicit cognition and to prevent the interference of consciousness, which is an effective method to evaluate NSSI.On the basis of introducing the background of implicit attitude, this paper summarized the research progress of implicit attitude in distinguishing and predicting NSSI from behavioral and neuroimaging perspectives.Firstly, compared with the group without NSSI history, the NSSI group had a more recognized implicit attitude towards NSSI, which was correlated with the frequency and severity of NSSI.Secondly, compared with other known traditional predictors, whether implicit attitude is a better predictor of subsequent behavior of NSSI remains controversial.Finally, there are not many studies on the biological basis of implicit attitude towards NSSI in NSSI populations.Preliminary results suggest that the activation of salience networks and the reduction of gray matter volume in some brain regions (such as the dorsal striatum) may be related to implicit attitude in NSSI populations.To sum up, measuring implicit attitudes towards NSSI is useful for screening and predicting people at risk for NSSI, especially when individuals have false reports or low self-awareness.In addition, this paper also put out some shortcomings for future research and clinical intervention.

Trend analysis of Cite Space-based research on non-suicidal self-injury / 中国实用护理杂志

Objective:To summarize the hotspots and developmental status of non-suicidal self-injury research by clustering and co-occurrence to the literature on non-suicidal self-injury on the basis of Cite Space, and in order to provide references for future research and intervention.Methods:Non-suicidal self-injury literature included in the Web of science core collection from January 1975 to August 2020 was searched, and the included literature was visualized and analyzed using Cite Space 5.5.R2 knowledge mapping software.Results:A total of 974 articles were retrieved, and the number of articles published showed an increasing trend year by year, mostly in developed countries. The country with the highest cumulative number of articles was the United States, with a total of 412 articles, and the first organization was Katholieke Univ Leuven, with a total of 42 articles. Key words co-occurrence and clustering showed that the current research focus was on adolescents, suicidal behavior, dialectical behavior therapy, and borderline personality disorder. The most cited literature was by Muehlenkamp.Conclusions:Non-suicidal self-injury research has developed rapidly in recent years. At present, non-suicidal self-injury population, related intervention measures, screening and evaluation tools, Meta-analysis and risk factor analysis are its research frontiers and hot spots.
