Non-suicidal self-injury and identity distress in Flemish adolescents: Exploring gender differences and mediational pathways

There is an increasing amount of research that examines non-suicidal self-injury (NSSI) in relation to identity formation in adolescents. However, little or no research to date has explored associations between NSSI and identity distress in specific domains. To address this shortcoming, we assessed NSSI, identity distress, anxiety, and depression using self-report questionnaires in 568 high school students. Gender differences in NSSI were found with lifetime prevalence of NSSI being twice as high in females as compared to males. Gender differences in terms of identity domains were also significant; adolescent females showed higher levels of distress in the identity domains of career goals, friendship, and group loyalties as compared to males. Adolescents engaging in NSSI showed higher distress in domains of long-term goals, friendship, sexual orientation and behavior, values and beliefs. Results indicated that it was not distress in specific domains as such but the impairment due to daily impact of identity distress that explained additional variance in lifetime prevalence of NSSI above and beyond gender, age, depression, and anxiety. We also demonstrated that gender differences in lifetime prevalence of NSSI were mediated by differences in such identity impairment. Clinical implications of these findings are discussed.     

Self-Cutting and Suicidal Ideation among Adolescents: Gender Differences in the Causes and Correlates of Self-Injury

In recent years, non-suicidal self-injury (NSSI) among adolescents has been identified as alarmingly common place. Some studies have suggested that more than one in eight adolescents have engaged in self-cutting or other self-injuring behaviors. Even more of a concern is that self-injury often foreshadows suicide or suicide attempts. With self-cutting common in middle and high schools, understanding the antecedents and correlates of such behavior may help counselors and others public health officials identify troubled students and initiate preventative measures. This study utilizes data from 2,639 high school students from the Delaware Youth Risk Behavior Survey to investigate the gender differences in NSSI and suicidal ideation. Overall, 13% reported engaging in NSSI within the past year, with females reporting significantly higher rates (17%) of NSSI than males (9%). Results indicate that there are significant gender differences in NSSI and suicidal thoughts based upon previous victimization experiences, reported substance use, depression, health behaviors, and sexual orientation.     

Non-Suicidal Self-Injury Among Male Adjudicated Adolescents: Psychosocial Concerns,Coping Responses,Diagnoses, and Functions

Non-suicidal self-injury (NSSI) refers to self-inflicted physical injury without suicidal intent. NSSI is particularly common in forensic settings and associated with several psychosocial concerns, coping responses, diagnoses, and functions, but little information is available regarding NSSI in adjudicated male adolescents. The present study examined the frequency and types of NSSI among adjudicated male adolescents (n?=?103) and assessed the relationships between NSSI history, psychosocial concerns, coping responses, diagnoses, and functions within this population. Approximately two-thirds (66%) reported NSSI history. Participants with NSSI history reported poorer social adaptation and greater alienation and boredom, aggression, and emotional lability than controls. Youth with high-frequency NSSI were also more likely to utilize emotional discharge as an unhealthy coping response than controls. In addition, participants with high-frequency NSSI were more likely than controls to meet criteria for a mood or anxiety disorder. Function of NSSI primarily surrounded anxiety reduction/affect regulation, punishment, dissociation reduction, and social/sensation-seeking. NSSI appears to be prevalent among male adjudicated youths, and the findings suggest that the relationship between NSSI history, psychosocial concerns, coping responses, and functions is nuanced and could inform more calibrated assessment and treatment strategies.     

Adolescent non-suicidal self-injurious behavior: The latest epidemic to assess and treat

Non-suicidal self-injury (NSSI) among adolescents is a serious and prevalent problem. This article reviews the epidemiological data as well as the existing treatments for adolescents who engage in NSSI. The authors also present the unique features of dialectical behavior therapy, the gold-standard evidence-based treatment for adults who engage in NSSI, and discuss its promise as an effective treatment for adolescents who engage in NSSI. Finally, the authors present a clinical vignette of an adolescent engaging in NSSI and how DBT works to target this maladaptive behavior.This article reviews first the epidemiological data and then the existing treatments for adolescents engaging in non-suicidal self-injurious behavior (NSSI). Next, the authors present the unique features of one particular therapy, called dialectical behavior therapy, for adolescents who engage in NSSI. Finally, the article concludes with a clinical vignette in which dialectical behavior therapy is applied to an adolescent engaging in NSSI.     

Dating Violence Victimization,Dispositional Aggression,and Nonsuicidal Self‐Injury among Psychiatrically Hospitalized Male and Female Adolescents

The objective of the current study was to characterize the association between dating violence victimization and dispositional aggression in predicting nonsuicidal self‐injury (NSSI) among psychiatrically hospitalized male and female adolescents. One hundred fifty‐five adolescents (ages 13–17) and their parents completed the Schedule for Affective Disorders and Schizophrenia for School‐Age Children clinical interview to assess NSSI and child abuse; adolescents completed self‐report measures of aggression and dating violence victimization (verbal, physical, and sexual). Dating violence victimization and NSSI were found to be highly prevalent among both males and females in this psychiatric inpatient sample. Two moderational models were supported, wherein dating violence was associated with NSSI in the context of elevated trait anger in males and indirect aggression in females. Findings suggest that helping victims of dating violence acquire skills to address certain forms of dispositional aggression may attenuate NSSI.     

Frequency of Nonsuicidal Self‐Injury in Adolescents: Differences in Suicide Attempts,Substance Use,and Disordered Eating

The relationship between frequency of nonsuicidal selfinjury (NSSI) and suicide attempts, substance use, and disordered eating was assessed in a community sample of 4,839 adolescents, 922 of whom reported NSSI in the past year. It was expected that the engagement in risk behaviors would significantly increase as NSSI frequency increased. Participants completed the Youth Risk Behavior Survey (Centers for Disease Control and Prevention, 2009) and were subdivided into five NSSI frequency groups: none, 1 time, 2–3 times, 4–5 times, and 6 or more times. A one‐way MANOVA found significant mean differences for all variables across NSSI frequency groups. The no NSSI group was significantly lower than all other groups on all variables. For suicide attempts, all frequency groups were significantly different from each other, with attempt frequency increasing with each increase in NSSI frequency. The six or more group reported significantly more substance use and disordered eating than all other groups. Overall, adolescents with more frequent NSSI represent a group at risk for concurrent unhealthy behaviors and suicide attempts.     

The Interactive Effects of Impulsivity and Negative Emotions on Adolescent Nonsuicidal Self‐injury: A Latent Growth Curve Analysis

This study employed latent growth curve analysis to evaluate the interactive effects of two specific facets of impulsivity (i.e., negative urgency [NU] and premeditation [PRE]) and negative emotions (NE) on the developmental trajectory of nonsuicidal self‐injury (NSSI) among 3,453 (57% females) Chinese community adolescents. Participants completed questionnaires assessing NSSI, NU, PRE, and NE (i.e., depression, anxiety, and stress) at three waves of time. The initial levels of NE and NU significantly predicted the initial level of NSSI. Changes in NE and NU significantly predicted change in NSSI. Moreover, the initial levels of NU and PRE significantly moderated the relationship between the initial levels of NE and NSSI, such that among individuals with higher NU or less PRE, the three NE were associated with a higher level of NSSI. Additionally, among individuals with a faster increase in NU, depression and anxiety were associated with a faster increase in NSSI. These findings suggest that adolescents with trait impulsivity, especially in the form of NU, are more vulnerable to the engagement in NSSI.     

Cognitive and Social Factors Associated with NSSI and Suicide Attempts in Psychiatrically Hospitalized Adolescents

Although non-suicidal self-injury (NSSI) and suicide attempts (SA) frequently co-occur among youth, there is increasing evidence that both the risk factors and the phenomenology of the behaviors are distinct. This study examined how individuals who engage in NSSI only, individuals who attempt suicide only, and those who have histories of both NSSI and at least one suicide attempt may differ in terms of cognitions and perceived social support. Participants were 185 adolescents (78.1 % female) between the ages of 13 and 18 recruited from a psychiatric inpatient facility in the northeastern United States. One hundred forty-eight teens were identified with a history of self-injurious behavior and divided into three groups: NSSI only (n?=?45), SA only (n?=?24) or both NSSI and SA (NSSI+SA; n?=?79). Analyses showed that the NSSI+SA group exhibited more cognitive errors, negative self-statements, and negative views of self, world, and future, as well as less perceived familial support than either the NSSI or SA only groups. There were no differences between groups on perceived support from teachers or peers. No significant demographic or diagnostic differences were found between the NSSI and SA groups. Limitations and clinical implications of the current research are discussed.     

Nonsuicidal Self‐injury in Asian Versus Caucasian University Students: Who,How, and Why?

The correlates of nonsuicidal self‐injury (NSSI) among Asian and Caucasian university students; differences in the rates, frequency, forms, severity, and emotional contexts of NSSI among self‐injuring students; and whether Asian students who are highly oriented toward Asian culture differed from those less oriented toward Asian culture in NSSI characteristics were investigated. University students (N = 931), including 360 Caucasian students (n = 95, 26.4%, with a history of ≥ 1 episode of NSSI) and 571 Asian students (n = 107, 18.7%, with a history of NSSI), completed questionnaires assessing NSSI, acculturation, and putative risk factors for NSSI. Caucasian students were more likely to report NSSI, particularly cutting behavior, self‐injured with greater frequency and versatility, and reported greater increases in positively valenced, high arousal emotions following NSSI, compared to Asian students. Among Asian students, obsessive–compulsive symptoms, experiential avoidance, and anger suppression increased the likelihood of reporting a history of NSSI. Among Caucasian students, lack of emotional clarity and anger suppression increased likelihood of NSSI. Finally, some tentative findings suggested potentially important differences in rates and frequency of NSSI among Asian students who were highly oriented toward Asian culture compared with those less oriented toward Asian culture.     

Peer influence and adolescent nonsuicidal self-injury: A theoretical review of mechanisms and moderators

Nonsuicidal self-injury (NSSI) is an increasingly prevalent health risk behavior among adolescents and represents a significant public health concern. Although researchers have identified numerous antecedents or risk factors that precede engagement in NSSI behaviors, few studies have examined the role of peer influence processes. Yet, recent research suggests that adolescents may be more likely to engage in NSSI when close friends or other peers engage in similar behaviors. The following paper reviews past research on peer influence effects, including potential mechanisms and moderating variables. Methodological considerations for future research on peer influence and NSSI are discussed.     

Peer Victimization and Suicidal Thoughts and Behaviors in Depressed Adolescents

Suicide is a leading cause of death among youth worldwide, and depressed adolescents are at a significantly elevated risk to report suicidal ideation, planning, and attempts. Peer victimization is a robust predictor of adolescent suicidal thoughts and behaviors (STBs), but little research has focused on why bullying leads to suicidal thoughts and behaviors. To address this empirical gap, we recruited 340 (246 female) depressed adolescents ages 13–19 (M = 15.59, SD = 1.41) within 48 h of admission for acute psychiatric treatment. At the initial assessment, participants were administered clinical interviews characterizing psychopathology, nonsuicidal self-injury, and STBs (ideation, plans, and attempts). Further, they completed questionnaires assessing 3 forms of victimization (overt, relational, and reputational), recent risky behavior engagement, and psychiatric symptom severity. Controlling for internalizing symptoms and age, overt and reputational bullying were associated with more frequent past month suicide attempts, but not suicide ideation. Past month risky behavior engagement, but not NSSI, mediated the relation between victimization and attempts. However, sex differences revealed that this effect only held for males whereas bullying was directly associated with suicide attempts among females. In contrast, overt and relational bullying were non-linearly associated with suicide plans, and these relations were not mediated by risky behaviors or NSSI. Results highlight the complex network of factors that lead victimized adolescents to engage in STBs and may inform targeted suicide prevention and intervention programs.     

The Best Friend and Friendship Group Influence on Adolescent Nonsuicidal Self-injury

This study examined associations of peer socialization and selection, over time, with nonsuicidal self-injury (NSSI) among 5,787 (54.2 % females) Chinese community adolescents. Both effects were tested using two aspects of adolescents’ friendship networks: the best friend and the friendship group. Participants completed questionnaires assessing NSSI, depressive symptoms and maladaptive impulsive behaviors at two waves of time over a 6-month period. Results showed that even after controlling for the effects of depressive symptoms and maladaptive impulsive behaviors, the best friends’ engagement in NSSI still significantly predicted adolescents’ own engagement in NSSI. Adolescents’ friendship groups’ NSSI status also significantly predicted their own NSSI status and frequency. Additionally, adolescents with NSSI tended to join peer groups with other members also engaging in NSSI.     

Factors Associated with Current Versus Lifetime Self‐Injury Among High School and College Students

We sought to identify factors associated with current versus lifetime nonsuicidal self‐injury (NSSI) and factors that show consonant and distinct relationships with current NSSI for adolescents and young adults. Data came from a population‐based survey of high school students (n = 9,985) and a national survey of college students (n = 7,801). Among both samples, factors associated with current NSSI included male gender, younger age, greater depressive symptoms, more hopelessness, and being the victim of a verbal or physical assault. For high school students, greater anxiety, and for college students, identifying as non‐White, negative perceptions of one's weight, a same‐sex sexual experience, and involvement in dating violence also distinguished the groups. Findings suggest that clinical and research assessments of lifetime NSSI might not extend to current behavior, and some differences exist in the factors associated with current behavior between adolescents and young adults. Clinical practice and prevention programming efforts should target certain intrapersonal and interpersonal factors associated with current NSSI among younger students during stressful transition periods in their lives, such as entering high school or college, when they might consider initiating or continuing this behavior.     

Nonsuicidal Self‐Injury among Adolescents: A Training Priority for Primary Care Providers

Primary care providers were surveyed to determine how prepared they feel to address nonsuicidal self‐injury (NSSI) among adolescents, their interest in training on NSSI, and factors associated with routinely asking about NSSI when providing health supervision. Participants included family medicine physicians (n = 260), pediatricians (n = 127), family nurse practitioners (n = 96), and pediatric nurse practitioners (n = 54). Almost 50% felt unprepared to address NSSI, and over 70% wanted training in this area. Overall, relative to other areas of mental health care, clinicians felt least prepared to address and wanted more training on NSSI. Just 27% reported they routinely inquired about NSSI during health supervision. Factors associated with routinely asking about NSSI were identifying as female (OR = 2.37; 95% CI = 1.25–4.49), feeling better prepared to address NSSI (OR = 1.51; 95% CI = 1.04–2.20), and more frequently using a psychosocial interview to identify adolescents in distress (OR = 1.23; 95% CI = 1.02–1.48). Teaching clinicians to assess NSSI within a psychosocial interview may increase screening for and identification of the behavior among adolescents in primary care.     

Gender differences in anger and fear as a function of situational context

Gender differences in the reported intensity of anger and fear toward hypothetical males and females were explored in three age groups (6–12 year olds, 14–16 year olds, and adults over 30) located in two different geographic areas. The samples were primarily Caucasian and included a wide range of socioeconomic groups. Subjects reported on the intensity of feelings elicited by characters in an emotion story task in which three aspects of situational context were varied: the gender of the story characters eliciting the feeling (all situations), the stereotypic gender-typed or cross-gender behavior of the eliciting character (four situations), and the affective quality of the situations (four situations). Across all three age groups, situations that were frightening, anger-provoking, or that depicted stereotypic male-negative behavior elicited the most consistent subject gender and character gender differences in reported fear and anger. Relative to males, females of all ages reported more fear in frightening, anger-producing, and male-negative stereotypic situations. Males were reported to be more frightening and anger-producing than were females in those same situations. The data also suggested that with development, females reported less intense fear of females, while males reported less intense fear of males.This research was supported by a Gender Roles grant from the Rockefeller Foundation. We appreciate their support. We would also like to thank the public school systems of Milton, Norwood, and Watertown, Massachusetts, and Saskatoon, Saskatchewan, Canada. Finally, we would like to thank Lance Davidow, John Houlihan, and Theodore Cross for statistical consultation and/or computer programming, as well as all the parents, children, and adolescents who participated in the study.     

Childhood Abuse,Nonsuicidal Self‐Injury,and Suicide Attempts: An Exploration of Gender Differences in Incarcerated Adults

The relationship between types of childhood abuse, suicide attempts, and nonsuicidal self‐injury (NSSI) was examined in a sample of 415 incarcerated adults (268 men, 147 women). Men and women were equally likely to experience childhood abuse, although women were more likely to report sexual abuse and men were more likely to report emotional neglect. Sexual abuse was the only type of abuse found to predict NSSI and suicide attempts in women. For men, physical abuse and physical neglect were significant predictors of NSSI and suicide attempts, respectively. Gender differences exist and should be examined in future research in this area.     

Peer Influence and Nonsuicidal Self Injury: Longitudinal Results in Community and Clinically-Referred Adolescent Samples

Research suggests that adolescents’ engagement in nonsuicidal self-injurious (NSSI) behaviors may be increasing over time, yet little is known regarding distal longitudinal factors that may promote engagement in these behaviors. Data from two longitudinal studies are presented to examine whether NSSI may be associated with peer influence processes. Study 1 included 377 adolescents from a community-based sample; Study 2 included 140 clinically-referred adolescents recruited from a psychiatric inpatient facility. In Study 1, adolescents’ NSSI was examined at baseline and one year later. Adolescents’ nominated best friend reported their own levels of NSSI. In Study 2, adolescents’ NSSI was examined at baseline as well as 9 and 18-months post-baseline. Adolescents’ perceptions of their friends’ engagement in self-injurious behavior (including suicidality) and depressed mood also were examined at all three time points. Baseline depressive symptoms were measured in both studies; gender and age were examined as moderators of peer influence effects. Results from both studies supported longitudinal peer socialization effects of friends’ self-injurious behavior on adolescents’ own NSSI for girls, but not for boys, even after controlling for depressive symptoms as a predictor. Study 1 suggested socialization effects mostly for younger youth. Results from Study 2 also suggested longitudinal socialization effects, as well as peer selection effects; adolescents’ NSSI was associated with increasing perceptions of their friends’ engagement in depressive/self-injurious thoughts and behavior. Findings contribute to the nascent literature on longitudinal predictors of NSSI and to work on peer influence.     

Risk of suicidal ideation in adolescents with both self-asphyxial risk-taking behavior and non-suicidal self-injury

This study examined adolescent participation in self-asphyxial risk-taking behaviors (SAB), sometimes known as the "choking game," and its relationship with other adolescent risk behaviors, including non-suicidal self-injury (NSSI). Researchers proposed that participation in SAB and NSSI would be associated with suicidal behavior, disordered eating, and substance use. Using a large community-based sample, results revealed preliminary associations between SAB and other risk-taking behaviors. Adolescents who had engaged in both SAB and NSSI reported more concurrent risk behaviors than adolescents who participated in only one of the behaviors or neither behavior. Results indicate that greater awareness of SAB is important, and continued research can evaluate the possible link between the behavior and risk for suicide.     

Exploring the Reciprocal Relations between Nonsuicidal Self-Injury, Negative Emotions and Relationship Problems in Chinese Adolescents: A Longitudinal Cross-Lag Study

The present study explored the reciprocal relations between nonsuicidal self-injury (NSSI), negative emotions and relationship problems in a community sample of 2,435 (57.6% females) Chinese adolescents. Participants completed measures assessing 12 NSSI behaviors, three negative emotions (depression, anxiety and tension), and relationship problems at two time points over a 6-month period. A longitudinal cross-lag analysis was used to test the reciprocal relations among the studied variables. Results showed that after controlling for their initial associations, NSSI significantly predicted negative emotions over time but not vice versa, and relationship problems significantly predicted NSSI over time but not vice versa. Theoretical and clinical implications of these findings were discussed.
