Rates of non-suicidal self-injury in high school students across five years

Prevalence rate trends of borderline personality disorder symptoms and self-injurious behaviors in college students from 2017 to 2021

The current study examines the prevalence rates of borderline personality disorder (BPD) symptoms and nonsuicidal self-injury (NSSI) behaviors amongst college students over a five-year period, including pre- and during the COVID pandemic. Online prescreener surveys were completed by undergraduate students (n = 12,756) attending a large Southern Plains University every semester from Spring of 2017 to Spring of 2021. The percentage of students with NSSI history and significant BPD symptoms were visualized by semester to examine trends over time. A series of logistic regressions and negative binomial regressions were conducted on NSSI history and BPD symptoms to examine whether the endorsement rates have been increasing over time and to compare before and during COVID pandemic. There was an increasing trend of NSSI rates and significant BPD symptoms over time for all sexes. Furthermore, there was a steeper increase in BPD symptoms specifically in female students over the last five years. Additionally, there was a significant increase in odds of elevated BPD symptoms and NSSI behaviors in the college students enrolled during the COVID pandemic compared with pre-COVID. Overall, there has been an increasing trend in BPD symptoms and NSSI rates over the last few years, including during the COVID pandemic.

Impact of the COVID-19 and psychological risk factors on non-suicidal self-injury behavior among high school students: a one-year follow-up study

OBJECTIVES

Non-suicidal self-injury (NSSI) behavior is a severe public health issue in adolescents. This study investigated the possible impact of the coronavirus disease 2019 (COVID-19) and analyzed psychological risk factors on adolescent NSSI.

METHODS

A one-year follow-up study was conducted in September 2019 (Time 1) and September 2020 (Time 2) among 3588 high school students. The completed follow-up participants (N = 2527) were classified into no NSSI (negative at both time points), emerging NSSI (negative at Time 1 but positive at Time 2), and sustained NSSI (positive at both time points) subgroups according to their NSSI behaviors before and during the COVID-19 pandemic. Perceived family functioning, perceived school climate, negative life events, personality traits (neuroticism, impulsivity, and self-control) were assessed using self-report scales.

RESULTS

The data indicated an increase (10.3%) in the incidence of NSSI. Compared to no NSSI subjects, the emerging NSSI and sustained NSSI subgroups had lower perceived family functioning, higher neuroticism, higher impulse-system but lower self-control scores, and more negative life events. Logistic regressions revealed that after controlling for demographics, neuroticism and impulse-system levels at Time 1 positively predicted emerging NSSI behavior, and similarly, higher neuroticism and impulsivity and lower self-control at Time 1 predicted sustained NSSI behavior.

CONCLUSIONS

These findings highlighted the aggravated impact of the COVID-19 on NSSI, and suggested that individual neuroticism, impulsivity, and self-control traits might be crucial for the development of NSSI behavior among adolescent students.

Superior temporal gyrus and cerebellar loops predict nonsuicidal self-injury in major depressive disorder patients by multimodal neuroimaging

In major depressive disorder (MDD) patients, nonsuicidal self-injury (NSSI) is a common comorbidity, and it is important to clarify the underlying neurobiology. Here, we investigated the association of NSSI with brain function and structure in MDD patients. A total of 260 MDD patients and 132 healthy controls (HCs) underwent resting-state functional magnetic resonance imaging and three-dimensional T1-weighted structural scans. NSSI behaviour was assessed through interviews. Voxel-based morphometry analysis (VBM), regional homogeneity analysis (ReHo), functional connectome topology properties and network-based statistics were used to detect the differences in neuroimaging characteristics. Finally, the random forest method was used to evaluate whether these factors could predict NSSI in MDD. Compared with HCs, MDD patients with a history of NSSI showed significant right putamen grey matter volume (GMV), right superior orbital frontal cortex ReHo, left pallidum degree centrality, and putamen-centre function network differences. Compared to MDD subjects without NSSI, those with past NSSI showed significant right superior temporal gyrus (STG) GMV, right lingual gyrus ReHo, sigma and global efficiency, and cerebellum-centre function network differences. The right STG GMV and cerebellum-centre function network were more important than other factors in predicting NSSI behaviour in MDD. MDD patients with a history of NSSI have dysregulated spontaneous brain activity and structure in regions related to emotions, pain regulation, and the somatosensory system. Importantly, right STG GMV and cerebellar loops may play important roles in NSSI in MDD patients.

Adolescents with anorexia nervosa with or without non-suicidal self-injury: clinical and psychopathological features

PURPOSE

Anorexia nervosa (AN) and non-suicidal self-injury (NSSI) share typical onset in adolescence, greater prevalence in females and similar risk factors. Nevertheless, clinical features of eating disorders (ED) in this population are still under-investigated, especially associated to psychological features.

METHODS

The present study aims at comparing clinical and ED characteristics and psychopathological traits in a sample of 253 female adolescents with AN with or without NSSI and to determine possible clinical and psychological predictors on the presence of NSSI. The two groups were compared through multivariate analyses, while correlation and regression analyses were conducted to determine possible associations and predictors.

RESULTS

AN + NSSI group showed higher prevalence of binging-purging-type AN (p < .001), and mean higher age (p = .008) and Body Mass Index (BMI) (p = .002) than AN without NSSI group. Concerning psychological scales, AN + NSSI group showed higher scores in mostly of the sub-scale of the test Eating Disorders Inventory-3, higher scores at the scale for depression (p < 0.001) and higher scores at the three indexes of Symptom Checklist 90-Revised test, Global Severity Index (p < 0.001), Positive Symptoms total (p = .003) and Positive Symptom Distress Index (p < 0.001). No differences emerged at Children's Global Assessment Scale and at scale for evaluation of alexithymia. Regression analyses showed that a diagnosis of binging-purging-type AN (p = .001) predicts NSSI.

CONCLUSION

Results suggest that adolescents with AN and NSSI show peculiar clinical features with higher prevalence of binging-purging-type AN and more severe psychopathological traits than adolescents with AN without NSSI.

Self-injurious and suicidal behaviour in a transsexual adolescent and young adult population, treated at a specialised gender identity unit in Spain

INTRODUCTION

Nonsuicidal self-injury (NSSI) and suicidal behavior (SB) have a significant prevalence in transsexual people. The published data is confusing as it does not distinguish between ideation and realization, age groups, gender, or the degree of medical intervention. Their actual prevalence in Spain is unknown.

OBJECTIVE

Our objective was to investigate the prevalence of NSSI behavior and SB in adolescents and young transsexual adults, differentiating between ideation and consummated behavior, prior to their receiving any type of gender-affirming medical treatment.

MATERIAL AND METHODS

We retrospectively reviewed the medical history of a cohort of transsexual people aged between 10 and 35 years, treated at the Gender Identity Unit of the Valencian Community. We analyzed the data collected regarding the presence of four variables: NSSI ideation, NSSI behavior, ideas of suicide and suicide attempts, as well as differences according to age group and gender.

RESULTS

The final sample consisted of 110 transsexual men and 90 transsexual women. Of these, 21% had made a suicide attempt, 50% had had suicidal ideas, 31% had a history of NSSI behavior and 35% had had NSSI ideas. No differences were found based on gender. Regarding age, subjects under 20 years of age presented a significantly higher prevalence regarding suicidal ideas compared to young adults (43% vs. 25%), while in the remaining variables, no statistically significant differences were found.

CONCLUSIONS

The prevalence of a history of suicidal ideas and behavior in the Spanish adolescent and young transsexual population is significant and does not differ according to gender or age range. The prevalence of NSSI ideas and behavior differs and is more frequent in adolescent transsexuals.

The Role of Psychological Factors in Non-suicidal Self-injury of Female Adolescents

Background: Non-suicidal self-injury (NSSI) is defined as inflicting damage to one’s own body. It begins in adolescence and tends to become chronic. Objectives: Considering the high prevalence and chronicity of NSSI among girls, the present study aimed to investigate the factors affecting the prevalence of NSSI in female adolescents from their perspective. Methods: The participants consisted of 604 female high-school students in Saveh, aged 14 - 17 years (14.29 ± 1.11), who were selected via random cluster sampling from November 2018 to January 2019. They answered six questionnaires, including the Inventory of Statements About Self-injury (ISAS), Ways of Coping questionnaire (WCQ), Child Abuse Self-report scale (CASRS), Family Emotional Involvement and Criticism scale (FEICS), Emotion Reactivity scale (ERS), and Aggression questionnaire (AQ). Data were analyzed using logistic regression analysis. Results: The predictor variables of child abuse, emotion reactivity, perceived parental criticism, family emotional involvement, and problem- and emotion-focused coping styles could successfully distinguish NSSI individuals from those without NSSI (P < 0.05). There were no significant differences between minor and moderate groups. Conclusions: Family emotional support is a protective factor, while criticism, child abuse, and emotion-focused coping style are risk factors for NSSI.

Narratives of Self-Harm at School: Identifying Trajectories of Intervention in Educational Contexts

Recent studies have shown that self-harming behaviour is increasingly widespread among adolescents, in particular at school. However, educational institutions perceive themselves unable to cope with the phenomenon, searching for protocols and guidelines to improve its management. Considering schools as useful contexts for intercepting the young malaise, this study aims at exploring the main meanings of self-harming behaviours made within the educational cultural contexts starting from the student’s narrations, in order to understand the possible trajectories of practice. In two high schools we have collected 96 narratives of self-harm written by adolescents (mean age 14; 74% females), who have been engaged in non-suicidal self-injury once in their life. The analysis of the narratives, produced with the help of a software for the automatic qualitative analysis of texts, has allowed to identify four prevalent themes organized into three sense vectors. The findings highlighted significant gender differences in the representation of the experience of self-harm between males and females, as well as the importance of meaningful relationships developed in familiar and educational contexts, which may allow the help seeking process. The emerging of culturally-shared meanings among adolescents within the investigated contexts may allow to think about possible protocols of preventive and clinical practices in schools.

Global Lifetime and 12-Month Prevalence of Suicidal Behavior, Deliberate Self-Harm and Non-Suicidal Self-Injury in Children and Adolescents between 1989 and 2018: A Meta-Analysis

OBJECTIVE

This meta-analysis aimed to estimate the global lifetime and 12-month prevalence of suicidal behavior, deliberate self-harm and non-suicidal self-injury in children and adolescents.

METHODS

A systematic search for relevant articles published between 1989 to 2018 was performed in multiple electronic databases. The aggregate 12-month and lifetime prevalence of suicidal behavior, deliberate self-harm, and non-suicidal self-injury were calculated based on the random-effects model. Subgroup analyses were performed to compare the prevalence according to school attendance and geographical regions. Results: A total of 686,672 children and adolescents were included. The aggregate lifetime and 12-month prevalence of suicide attempts was 6% (95% CI: 4.7-7.7%) and 4.5% (95% CI: 3.4-5.9%) respectively. The aggregate lifetime and 12-month prevalence of suicidal plan was 9.9% (95% CI: 5.5-17%) and 7.5% (95% CI: 4.5-12.1%) respectively. The aggregate lifetime and 12-month prevalence of suicidal ideation was 18% (95% CI: 14.2-22.7%) and 14.2% (95% CI: 11.6-17.3%) respectively. The aggregate lifetime and 12-month prevalence of non-suicidal self-injury was 22.1% (95% CI: 16.9-28.4%) and 19.5% (95% CI: 13.3-27.6%) respectively. The aggregate lifetime and 12-month prevalence of deliberate self-harm was 13.7% (95% CI: 11.0-17.0%) and 14.2% (95% CI: 10.1-19.5%) respectively. Subgroup analyses showed that full-time school attendance, non-Western countries, low and middle-income countries, and geographical locations might contribute to the higher aggregate prevalence of suicidal behaviors, deliberate self-harm, and non-suicidal self-injury. Conclusions: This meta-analysis found that non-suicidal self-injury, suicidal ideation, and deliberate self-harm were the three most common suicidal and self-harm behaviors in children and adolescents.

Subgroups of Adolescent Girls With Borderline Personality Disorder Symptoms

The aim of this study was to determine whether borderline personality disorder (BPD) can be differentiated from other disorders in a clinical sample of adolescent girls. Participants (N = 75) were grouped based on the pattern of BPD symptom endorsement using a latent class analysis. Four latent classes were identified. The most impaired class endorsed seven BPD symptoms and an average of three comorbid disorders. An intermediate class endorsed three BPD symptoms and had the highest prevalence of PTSD (41.7%). A third class reported two BPD symptoms and had a high prevalence of anxiety disorders (62%). The fourth class had no BPD symptoms and, on average, one comorbid disorder. Only a small subset of these teenage girls met criteria for BPD, and they had distinct and severe impairment. The results suggest the modest likelihood of a BPD diagnosis in clinical samples of teenage girls, and to also be vigilant for PTSD.

DSM Borderline Criterion Function Across Age-Groups: A Cross-Sectional Mixed-Method Study

DSM-5 (Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition) Section II criteria for borderline personality disorder (BPD) lack developmental operationalization. The aim of the current study was to evaluate whether DSM criteria operate similarly across adolescents and adults to determine if developmental adjustment for DSM criteria was needed. Three age cohorts were recruited: adolescents (ages 12-17 years; n = 484), young adults (ages 18-25 years; n = 442), and adults (ages ≥26 years; n = 953). The Child Interview for DSM-IV BPD and the Structured Clinical Interview for DSM-IV Axis II disorders were administered to adolescents and adults, respectively. Item response theory methods were used to evaluate differential item (or criterion) functioning (DIF) of BPD criteria across adolescents and adults. Qualitative analyses were then used to evaluate the potential sources of DIF. Item response theory results demonstrated DIF across adolescents and adults for all DSM BPD criteria. Qualitative analyses suggested that the source of DIF was most likely due to rater/interviewer bias. Results furthermore suggested that behavioral criteria may represent the heterotypic features of BPD, while intra- and interpersonal criteria represent the homotypic features of the disorder. The article concludes with recommendations for developmentally informed guidelines for the assessment of BPD.

Assessing Non-Suicidal Self-Injury in the Laboratory

The majority of non-suicidal self-injury (NSSI) research has used self- or clinician-rated measures of behavior which (a) are subject to reporting biases, or (b) have limited use in experimental designs that could illuminate causal relationships. Laboratory-based behavioral tasks have therefore been developed to assess NSSI-related behaviors more directly. We reviewed the behavioral methods that have been developed to assess NSSI tendencies or behaviors over the past 30 years. Several categories of laboratory analogues were identified: NSSI-related stimuli (e.g., NSSI pictures, implicit association tasks, guided imagery), experimenter administered pain stimuli (e.g., cold, heat, pressure, shock, and blade), and self-selected pain stimuli (e.g., cold and shock). These behavioral methods assess various aspects of NSSI and all have distinct advantages and shortcomings. Overall, these approaches have made significant contributions to the field complementing self- and clinician-ratings.

N-Acetylcysteine for Nonsuicidal Self-Injurious Behavior in Adolescents: An Open-Label Pilot Study

BACKGROUND

Nonsuicidal self-injury (NSSI) is common in adolescents and young adults, and few evidence-based treatments are available for this significant problem. N-acetylcysteine (NAC) is a widely available nutritional supplement that has been studied in some psychiatric disorders relevant to NSSI including mood and addictive disorders. This pilot study tested the use of NAC as a potential treatment for NSSI in youth.

METHODS

Thirty-five female adolescents and young adults with NSSI aged 13-21 years were enrolled in this study that had an open-label, single-arm study design. All participants were given oral NAC as follows: 600 mg twice daily (weeks 1-2), 1200 mg twice daily (weeks 3-4), and 1800 mg twice daily (weeks 5-8). Patients were seen every 2 weeks throughout the trial, at which time youth reported the frequency of NSSI episodes. Levels of depression, impulsivity, and global psychopathology were measured at baseline and at the end of the trial using the Beck Depression Inventory-II (BDI-II), Barratt Impulsivity Scale, and Symptoms Checklist-90 (SCL-90).

RESULTS

About two-thirds of the enrolled female youth completed the trial (24/35). NAC was generally well tolerated in this sample. NAC treatment was associated with a significant decrease in NSSI frequency at visit 6 and visit 8 compared to baseline. We also found that depression scores and global psychopathology scores (but not impulsivity scores) decreased after NAC treatment. Decrease in NSSI was not correlated with decrease in BDI-II or SCL-90 scores, suggesting these might be independent effects.

CONCLUSION

We provide preliminary evidence that NAC may have promise as a potential treatment option for adolescents with NSSI. The current results require follow-up with a randomized, placebo-controlled trial to confirm efficacy.

Predicting Nonsuicidal Self-Injury in Borderline Personality Disorder Using Ecological Momentary Assessment

Borderline personality disorder (BPD) is a highly comorbid disorder, and these comorbidities increase the impairment associated with BPD. For example, depression, which occurs in the majority of individuals with BPD, increases the likelihood of an individual with BPD to engage in nonsuicidal self-injury (NSSI). Little research, however, has investigated potential mechanisms of NSSI engagement in this population. The current study aimed to fill this gap by examining momentary experiences, levels of distress tolerance, and NSSI among 51 individuals meeting current diagnostic criteria for BPD and a comorbid depressive disorder. Using data from an ecological momentary assessment across 7 days, it was found that daily urges to hurt oneself and impulsive urges, but not daily negative affect or aggressive urges, predicted NSSI occurrence. Furthermore, low levels of distress tolerance was a stronger predictor of NSSI behavior than daily experiences. These findings have important implications with regard to state versus trait dispositions in NSSI engagement among those with BPD and depression.

“I Do Want to Stop, At Least I Think I Do”: An International Comparison of Recovery From Nonsuicidal Self-Injury Among Young People

Phenomenological and cultural understandings of recovery from the perspective of individuals who engage in nonsuicidal self-injury (NSSI) are rare. The primary study objective was to understand similarities across three samples in (a) how young people define recovery from NSSI and (b) what they consider helpful approaches taken by parents and professionals to assist their recovery. Using a cross-national sample of young people ( n = 98) from Australia ( n = 48), Belgium ( n = 25) and the United States ( n = 25), we assessed their perspectives on NSSI. Consistent across all samples, young people defined recovery as no longer having the urge to self-injure when distressed, often displayed ambivalence about recovery, and reported it was helpful when parents and professionals were calm and understanding. Acceptance of recovery as a process involving relapses may need to be emphasized in NSSI treatment, to ease the pressure young people often place on themselves to stop the behavior outright.

National Trends in the Prevalence and Treatment of Depression in Adolescents and Young Adults

OBJECTIVES

This study examined national trends in 12-month prevalence of major depressive episodes (MDEs) in adolescents and young adults overall and in different sociodemographic groups, as well as trends in depression treatment between 2005 and 2014.

METHODS

Data were drawn from the National Surveys on Drug Use and Health for 2005 to 2014, which are annual cross-sectional surveys of the US general population. Participants included 172 495 adolescents aged 12 to 17 and 178 755 adults aged 18 to 25. Time trends in 12-month prevalence of MDEs were examined overall and in different subgroups, as were time trends in the use of treatment services.

RESULTS

The 12-month prevalence of MDEs increased from 8.7% in 2005 to 11.3% in 2014 in adolescents and from 8.8% to 9.6% in young adults (both P < .001). The increase was larger and statistically significant only in the age range of 12 to 20 years. The trends remained significant after adjustment for substance use disorders and sociodemographic factors. Mental health care contacts overall did not change over time; however, the use of specialty mental health providers increased in adolescents and young adults, and the use of prescription medications and inpatient hospitalizations increased in adolescents.

CONCLUSIONS

The prevalence of depression in adolescents and young adults has increased in recent years. In the context of little change in mental health treatments, trends in prevalence translate into a growing number of young people with untreated depression. The findings call for renewed efforts to expand service capacity to best meet the mental health care needs of this age group.

The Mediating Role of Self-Criticism in the Relationship between Parental Expressed Emotion and NSSI

Nonsuicidal self-injury (NSSI) is found at high rates among adolescents and young adults and is associated with many negative consequences, warranting additional research. Two factors that may contribute to NSSI during this time period are one's levels of self-criticism and perceptions of their parental relationships; however, these relationships have received limited attention. The purpose of this current study was to address this gap in the literature. Adolescents and young adults (n=294) completed measures of perceived parental expressed emotion, self-criticism, and NSSI. Participants with a history of NSSI reported perceiving their parents as providing less emotional support, inducing more irritation, being more intrusive, and expressing more criticism compared to those without a history of NSSI. These individuals also endorsed greater self-criticism. Further, self-criticism mediated the relationship between perceived parental expressed emotion and NSSI occurrence, such that those with higher reported self-criticism and greater perceived parental expressed emotion were more likely to engage in NSSI.

The prevalence of Nonsuicidal Self-Injury (NSSI) in a representative sample of the German population

BACKGROUND

Non-suicidal self-injury (NSSI) is a proposed new "condition for further study" in the DSM-5. To date no prevalence data has been available on this diagnostic entity from a representative sample of the general population.

METHODS

A representative sample of the German population (N = 2509, mean age = 48.8 years, SD = 18.1, female 55.4 %) completed the NSSI section of the German version of the Self-Injurious Thoughts and Behaviors Interview (SITBI-G).

RESULTS

A history of NSSI at least once during lifetime was reported by 3.1 % of all participants, with higher lifetime prevalence rates in younger age groups. DSM-5 NSSI disorder criteria were met by 0.3 %. The most common function of NSSI was automatic negative reinforcement (e.g. to alleviate negative feelings).

CONCLUSIONS

To the best of our knowledge, this is the first study reporting rates for the proposed NSSI category in DSM-5 from a representative sample of the general population. In comparison to findings from community samples of adolescents, adults seem to have lower lifetime prevalence rates of NSSI, thus making it necessary to emphasize prevention and treatment efforts in younger age groups.

Functions of nonsuicidal self-injury (NSSI): Cross-sectional associations with NSSI duration and longitudinal changes over time and following treatment

In this study, we sought to clarify if and how the functions of nonsuicidal self-injury (NSSI) relate to duration of NSSI or change over time. To accomplish this aim, we analyzed data obtained from routine clinical evaluations completed within a specialized acute-care treatment program for NSSI. Specifically, we examined how functions of NSSI vary between patients by duration of NSSI, how functions changed within patients over time, and how changes in NSSI functions related to treatment outcomes. Neither internal nor social functions were associated with NSSI duration between patients after controlling for relevant covariates. For patients completing two admissions assessments, internal and social functions decreased similarly over time, although the decrease in internal functions was no longer significant after controlling for decreases in NSSI urges. For patients who completed admissions and discharge assessments, internal and social functions decreased over the course of treatment, with larger decreases in internal functions. Decreases in both types of functions related to improved treatment outcomes. In conclusion, our results suggest that NSSI functions are generally stable across time, although decreases in NSSI functions may relate to clinical improvement.

The Relationship Between Nonsuicidal Self-Injury and Family Functioning: Adolescent and Parent Perspectives

We explored parent and adolescent reports of family functioning, how this differed if the parent was aware that their child self-injured, and how parental awareness of self-injury was related to self-injury frequency, self-injury severity, and help seeking. Participants were 117 parent-adolescent dyads, in 23 of which the adolescent self-injured. Adolescents who self-injured reported poorer family functioning than their parents, but parents who did not know about their child's self-injury reported similar functioning to parents whose children did not self-injure. Parents were more likely to know that their child self-injured when the behavior was severe and frequent. Help-seeking was more likely when parents knew about self-injury. Family-based interventions which emphasize perspective-taking could be used to effectively treat self-injury.

Non-Suicidal Self-Injury in Our Schools: A Review and Research-Informed Guidelines for School Mental Health Professionals

Non-suicidal self-injury (NSSI), the immediate and deliberate destruction of one’s own body tissue, without suicidal intent, and not for purposes that are socially accepted, is a critical concern for youth in schools. Despite significant scholarly advances and increasing clinical awareness of NSSI, many school mental health professionals (MHPs) continue to report feeling ill equipped to support students who self-injure, and emphasize a need for formal education about NSSI and its management in schools. Thus, the first part of this article summarizes current NSSI research on prevalence, age of onset, gender differences, functions, risk factors, and associations with suicide. Emerging from this review, the second part offers research-informed recommendations for MHPs managing NSSI in schools, including guidelines for (a) identifying students at elevated risk of self-injury, (b) developing a protocol for school personnel’s initial response to student self-injury, (c) first-level assessment of NSSI, and (d) managing critical issues related to NSSI contagion and online activity.

Beyond medicalization: Self-injuring acts revisited

For too long, medical/psychiatric and psychological studies, with focus on emotional sensitivity, personality traits, and correlation with psychopathology, have dominated research on self-injuring acts. The phenomenon thus has been defined as a predominantly medical issue. However, a large body of community prevalence studies show self-injuring acts to be a common phenomenon in society, and most of those who self-injure are unknown in psychiatric or other clinical settings. This article describes and analyzes the medicalization of self-injuring acts and argues a need to move research on self-injuring acts out of the medical paradigm. There is a need to explicitly explore the impact of social, cultural, structural, and gendered factors surrounding and influencing self-injuring acts. A non-medical approach, beyond the limits of the medical perspective, would feed research forward and create a more nuanced view on this widespread social phenomenon.

Nonsuicidal self-injury across cultures and ethnic and racial minorities: A review

The field of nonsuicidal self-injury (NSSI) is dominated by research conducted with Caucasian-majority samples in Western countries such as United States, Canada, Australia and European countries. This article critically reviewed the empirical research on NSSI in non-Western countries and among ethnic/racial minority individuals who live in the West to give voice to and understand the patterns of NSSI among individuals who do not fall within the dominant Caucasian majority. The study found both similarities and differences between Western and non-Western data in terms of characteristics and functions of NSSI. Differences in gender patterns in regards to prevalence of NSSI and methods used as well as presence of a more relational functionality of NSSI rather than emotion regulation functionality were two points of divergence in the findings of these studies. In addition, the findings seem to indicate that the role of ethnicity/race is mediated by important factors such as socioeconomic status (SES) and gender. Existing gaps in the literature and suggestions for further research are discussed.

Self-injurious implicit attitudes among adolescent suicide attempters versus those engaged in nonsuicidal self-injury

BACKGROUND

Suicide is among the most important mental health issues affecting adolescents today despite much research on its detection and prevention. Beyond suicide attempts (SAs), clinicians are increasingly confronted with another, potentially related problem: non-suicidal self-injury (NSSI)-defined as the deliberate destruction of body tissue without intent to die. NSSI may increase risk for making an SA by sevenfold, but many studies examining this link have involved youths engaging in both NSSI and SAs. Thus, there is a need to compare homogeneous groups of adolescents engaged in NSSI-only or SA-only, but not both, to advance what is known about each form of self-harm. The self-injurious implicit association task (SI-IAT) is a particularly important computerized behavioral task to study such adolescents because the SI-IAT provides objective behavioral data about problems for which people may lack insight or be motivated to conceal, such as SAs and NSSI.

METHODS

We evaluated implicit associations with cutting and death/suicide using the computerized SI-IAT in three mutually exclusive groups: (1) adolescents who made an SA but had never engaged in NSSI (n = 47); (2) adolescents who engaged in NSSI but had never made an SA (n = 46); and (3) typically developing control (TDC) adolescents without history of psychiatric problems (n = 43).

RESULTS

Nonsuicidal self-injury participants had stronger identification with cutting versus no cutting than either SA or TDC participants. Contrary to our hypothesis, NSSI participants had stronger identification with suicide/death versus life than either SA or TDC participants.

CONCLUSIONS

Strong implicit attitudes towards suicide/death among adolescents with NSSI without a prior SA suggest that clinicians should not dismiss NSSI as not serious. Further work is required to elucidate the mechanism by which youths engaged in NSSI acquire these stronger identifications and make a first-time SA to develop novel treatment and prevention strategies blocking this transformation, ultimately reducing youth suicide.

Non-Suicidal Self-Injury among Adolescents in Amman, Jordan

While previous research has demonstrated cross-national differences in non-suicidal self-injury (NSSI), most studies to date have taken place in North America. The present study investigated the prevalence and characteristics of NSSI in a sample of 952 Jordanian adolescents (49.8% female) between the ages of 11-19 years. Participants completed a screening measure to assess occurrence of NSSI and its characteristics. Results indicate an overall lifetime prevalence of 22.6% (n = 215), with significantly more males (26.98%, n = 129) than females (18.14%, n = 86) reporting having engaged in NSSI at least once in their lifetime. This study provides empirical evidence that adolescent engagement in NSSI occurs at similar prevalence levels in Jordan, relative to North American samples, whereas gender comparisons of prevalence and characteristics revealed several differences.

Non-suicidal self-injury in adolescence: a longitudinal study of the relationship between NSSI, psychological distress and perceived parenting

OBJECTIVE

The present study investigates whether either adolescents' psychological distress and/or perceived parenting predicted the occurrence of NSSI. Furthermore, the consequences of NSSI are examined in a three-wave longitudinal study.

DESIGN

The sample at time 1 (age 12) consisted of 1396 adolescent reports and 1438 parent reports. At time 2 (age 13), 827 adolescent reports and 936 parent reports were obtained. Time 3 (age 14) included 754 adolescent reports and 790 parent reports. Psychological distress of adolescents was measured using the Strengths and Difficulties Questionnaire. Perceived parenting behaviors were examined by the Parental Behavior Scale and the Psychological Control Scale.

RESULTS

A total of 10% of the adolescents engaged in NSSI at least once before age 15. Higher psychological distress of adolescents at time 1 was associated with the presence of NSSI at time 2 or 3. The association between psychological distress at time 1 and perception of decreased parental rule setting at time 3 was mediated by the presence of NSSI at time 2.

CONCLUSIONS

The present study showed that psychological distress at age 12 predicts NSSI over time and that parental awareness of NSSI changes the perception of parenting behaviors.

Prevalence of nonsuicidal self-injury in nonclinical samples: systematic review, meta-analysis and meta-regression

Published prevalence estimates of nonsuicidal self-injury (NSSI) among nonclinical samples are highly heterogeneous, raising concerns about their reliability and hindering attempts to explore the alleged increase in NSSI over time. Accordingly, the objectives of this study were to investigate the influence of methodological factors on heterogeneity in NSSI prevalence estimates, explore changes over time, and estimate overall international NSSI prevalence. Results showed that methodological factors contributed over half (51.6%) of the heterogeneity in prevalence estimates, and, after adjusting for these factors, NSSI prevalence did not increase over time. Overall, pooled NSSI prevalence was 17.2% among adolescents, 13.4% among young adults, and 5.5% among adults. Clearly, development of standardized methodology in NSSI research is crucial if accurate estimates are desired.

Nonsuicidal self-injury and its relation to personality traits in medical students

Nonsuicidal self-injury (NSSI) has a high prevalence among the general undergraduate population, but as yet, no study has investigated the rate of NSSI among medical students despite the high levels of depression and suicidal ideation found in this population. Our study aimed to estimate the prevalence of NSSI and suicide attempts in German medical students and explore the associations between these behaviors and the five major personality traits. Seven hundred fourteen medical students (67% women; age range, 18-35 years; mean age, 23.1 years) participated in an online survey. We report a lifetime prevalence of 14.3% for NSSI and 1.5% for suicide attempt. The students with NSSI showed higher levels of neuroticism and openness to experience but lower levels of conscientiousness and extraversion on the NEO Five-Factor Inventory. Our results are in line with previous research from other countries regarding the prevalence of NSSI among students and its association with personality.

Differences between non-suicidal self injury and suicide attempt in Chinese adolescents

PURPOSE

Self-harm behaviors are predominant health risks among adolescents. This study aimed to elucidate the lifetime prevalence and differences in social psychological factors between non-suicidal self-injury (NSSI) and suicide attempt (SA) among Chinese adolescents.

METHOD

Data were collected from 2131 middle school students with a mean age of 13.92 (SD 1.63) years (49.1% girls). Participants were asked to self-report NSSI and SA over their lifetime. Post hoc tests pairwise comparisons and multinomial logistic regression analyses were conducted to investigate differences and similarities between subjects with NSSI and attempted suicide.

RESULTS

The prevalence of lifetime NSSI and SA endorsed by the participants were 23.2% and 3.2%, respectively, and the co-occurrence of these two behaviors (NSSI+SA) was reported to 2.3%. Boys were comparable with girls in the prevalence rate of NSSI, but not in the rate of SA. It revealed that single-child was not the risk factor for self-harm behavior in Mainland China, but lower higher family cohesion and adaptability. Factors that distinguished the NSSI+SA group from the NSSI only group were female gender, lower grade, impulsivity, health risk behaviors and family cohesion. Being female gender, single-parent family, depressive symptoms and impulsivity were factors differentiating attempted suicide from NSSI.

CONCLUSIONS

Our findings suggest that Chinese adolescents engaging both in NSSI and SA had severe suicidal attempts and were different from those who engaged in NSSI alone.

Measurement of perceived functions of non-suicidal self-injury for Chinese adolescents

Due to the lack of validated assessment tools for motives of non-suicidal self-injury behaviors in the Chinese contexts, this study aims to evaluate the psychometric properties of the Chinese version of the Functional Assessment of Self-Mutilation (C-FASM). A total of 345 secondary school students (mean age = 11.41 years), who reported non-suicidal self-injury in the past year, voluntarily participated in the questionnaire survey. Confirmatory factor analysis results supported a second-order model of 4 motivational factors. The overall scale scores had significant correlations with depression, anxiety, impulsiveness, self-esteem, social support, and suicidal ideation. The internal consistency of the scale was also satisfactory. The C-FASM is a valid and reliable instrument for assessing non-suicidal self-injury among nonclinical Chinese adolescents.

Nonsuicidal self-injury and gender: patterns of prevalence, methods, and locations among adolescents

Nonsuicidal self-injury (NSSI) among adolescents is a growing concern. However, little is known about gender and features of this behavior. Gender differences in NSSI among a sample of 7,126 adolescents were investigated, 1,774 of whom reported having engaged in NSSI. Gender differences in prevalence, method, and location of NSSI were examined. Findings revealed that females reported higher rates of NSSI, more cutting and scratching, and more injuries to arms and legs than their male counterparts. Males reported more burning and hitting-type behavior, as well as injuries to the chest, face, or genitals. This highlights an interesting pattern of NSSI, which future research should consider to accurately examine NSSI in females and males.

International prevalence of adolescent non-suicidal self-injury and deliberate self-harm

BACKGROUND

The behaviours of non-suicidal self-injury (NSSI) and deliberate self-harm (DSH) are prevalent among adolescents, and an increase of rates in recent years has been postulated. There is a lack of studies to support this postulation, and comparing prevalence across studies and nations is complicated due to substantial differences in the methodology and nomenclature of existing research.

METHODS

We conducted a systematic review of current (2005 - 2011) empirical studies reporting on the prevalence of NSSI and DSH in adolescent samples across the globe.

RESULTS

Fifty-two studies fulfilling the inclusion criteria were obtained for analysis. No statistically significant differences were found between NSSI (18.0% SD = 7.3) and DSH (16.1% SD = 11.6) studies. Assessment using single item questions led to lower prevalence rates than assessment with specific behaviour checklists. Mean prevalence rates have not increased in the past five years, suggesting stabilization.

CONCLUSION

NSSI and DSH have a comparable prevalence in studies with adolescents from different countries. The field would benefit from adopting a common approach to assessment to aide cross-cultural study and comparisons.

Depressive symptoms and deliberate self-harm in a community sample of adolescents: a prospective study

The associations between depressive symptoms and deliberate self-harm were studied by means of a 2-wave longitudinal design in a community sample of 1052 young adolescents, with longitudinal data for 83.6% of the sample. Evidence was found for a bidirectional relationship in girls, with depressive symptoms being a risk factor for increased self-harm one year later and self-harm a risk factor for increased depressive symptoms. Cluster analysis of profiles of depressive symptoms led to the identification of two clusters with clear depressive profiles (one severe, the other mild/moderate) which were both characterized by an overrepresentation of girls and elevated levels of self-harm. Clusters with more circumscribed problems were also identified; of these, significantly increased levels of self-harm were found in a cluster characterized by negative self-image and in a cluster characterized by dysphoric relations to parents. It is suggested that self-harm serves more to regulate negative self-related feelings than sadness.

Preventing non-suicidal self-injury in adolescents: the signs of self-injury program

Non-suicidal self-injury (NSSI) continues to be a problem among youth and there is a great need for programming aimed at reducing NSSI in adolescents. The signs of self-injury program is the first known NSSI school-based prevention program for adolescents that attempts to increase knowledge, improve help-seeking attitudes and behaviors, and decrease acts of NSSI. A total of five schools implemented the program in selected classrooms (n = 274 adolescents; 51.5% female, mean age = 16.07 years) that consisted of predominantly Caucasian (73%) adolescents. Researchers collected pre-post evaluation surveys of the program and feasibility interviews were conducted with the school guidance personnel who ran the program. Results indicated the prevention program did not produce iatrogenic effects, increased accurate knowledge and improved help-seeking attitudes and intentions among students. No significant changes were found in regards to self-reported formal help-seeking actions. Feasibility responses indicate the program is user-friendly and well received by school personnel. The data offer preliminary evidence that the program may be an effective prevention program for schools.
