Differences in features of non-suicidal self-injury according to borderline personality disorder screening status

An Investigation of the Mediating Roles of Emotion Regulation Difficulties, Distress Tolerance, Self-Compassion, and Self-Disgust in the Association Between Childhood Trauma and Nonsuicidal Self-Injury

OBJECTIVE

Childhood maltreatment has been associated as a risk factor with the development of nonsuicidal self-injury (NSSI), with difficulty in emotion regulation explaining the association. However, little is known about the potential factors that make some individuals with maltreatment history more vulnerable to difficulties in emotion regulation and, in turn, engage in NSSI. The current study aimed to examine the roles of distress tolerance, self-compassion, and self-disgust in the association between childhood maltreatment types and emotion regulation difficulty, which was expected to predict NSSI.

METHOD

The sample included 397 university students between the ages of 18 and 30. Participants completed self-report scales assessing childhood maltreatment, emotion regulation difficulty, distress tolerance, self-compassion, self-disgust, and NSSI using the paper-pencil and online methods. The mediation model suggested for the association between childhood maltreatment types and NSSI was tested using path analysis.

RESULTS

Low distress tolerance, low self-compassion, high self-disgust, and resulting high emotion regulation difficulty mediated the indirect effect of emotional neglect on NSSI.

CONCLUSION

The current study sheds light on various factors in the development and maintenance of NSSI and reveals three developmental pathways from emotional neglect in childhood to engaging in NSSI.HIGHLIGHTSEmotional neglect may be a distal risk factor for nonsuicidal self-injury (NSSI).Low distress tolerance and self-compassion and high self-disgust may increase the risk of NSSI.Emotion regulation difficulty may make people engage in NSSI to regulate emotions.

What aspects of mindfulness and emotion regulation underpin self-harm in individuals with borderline personality disorder?

BACKGROUND

Self-harm presents significant risk for individuals with borderline personality disorder (BPD). Both self-harm and BPD are associated with deficits in mindfulness and emotion dysregulation. Previous research suggests that thought suppression and emotional inexpressivity may underpin self-harm in people with BPD, suggesting potential links to self-harm functions common for those with BPD. More research is needed to strengthen our understanding of this relationship.

AIMS

This study examines how BPD symptoms, mindfulness, emotion dysregulation and self-harm functions are related.

METHODS

Australian community outpatients diagnosed with BPD (N = 110) completed measures of mindfulness, emotion dysregulation and self-harm functions. Serial mediation analyses were conducted to examine relationships between variables.

RESULTS

BPD symptoms, chronic emptiness, mindfulness skills, describing and non-reacting, emotion dysregulation areas of emotion regulation strategies and poor emotional clarity were associated with recent self-harm. Various combinations of describing, strategies and clarity mediated the path between emptiness and self-harm functions more likely to be endorsed by individuals with a diagnosis of BPD. Describing was associated with all but anti-suicide function, while strategies was associated with all but anti-dissociation.

CONCLUSION

The study highlights how individuals with BPD experiencing chronic emptiness may benefit from treatment targeting describing skills and adaptive emotion regulation strategies.

Understanding the subtypes of non-suicidal self-injury: A new conceptual framework based on a systematic review

Non-suicidal self-injury (NSSI) is a significant public health problem, but there is no consistent evidence of its risk factors. One possibility is that there are subtypes NSSI that have different risk factors and clinical symptoms. In this review we evaluated the evidence of subtypes to determine if there were consistent subtypes of NSSI that emerged across studies. Four databases (Medline; Embase; PsycINFO; Web of Science) were searched to identify studies that used data-driven approaches and were published before November 9, 2022. There were 21 studies with 23 unique samples for review. Most of the included studies used NSSI symptoms or personal characteristics as the subtyping indicators, revealing 2-5 subtypes of NSSI. Variations in subtyping indicators, sample characteristics, and statistical methods may have contributed to the inconsistent number and characteristics of subtypes across studies. A new conceptual framework is proposed to integrate these diverse findings, highlighting the important roles of NSSI function and psychological pain in differentiating NSSI subtypes. This framework sheds light on the differences among self-injurers and offers insights for future endeavors to address the complexities of NSSI.

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.

Investigation of the Subtypes of Nonsuicidal Self-Injury Based on the Forms of Self-Harm Behavior: Examining Validity and Utility via Latent Class Analysis and Ecological Momentary Assessment

BACKGROUND

This study aimed to empirically derive and validate subtypes of nonsuicidal self-injury (NSSI) based on the forms of self-harm behavior.

METHODS

Sixty young adults who exhibited repetitive NSSI completed a clinical interview and baseline measures, followed by a two-week ecological momentary assessment (EMA). A latent class analysis was administered to identify NSSI subtypes based on the forms of self-harm behavior. The subtypes were then compared to baseline clinical and EMA variables, including emotions and urges to self-harm.

RESULTS

The best-fitting model supported two subtypes: 1) substance abuse and suicide attempt subtype and 2) cutting and scratching subtype. The substance abuse and suicide attempt subtype reported a higher rate of engaging in lifetime suicide plans and suicide attempts and a higher number of lifetime suicide attempts. They also showed significantly higher severity of self-harm behavior, borderline personality traits, anger, posttraumatic symptoms, and difficulties in emotion regulation when compared to the cutting and scratching subtype. However, there was no inter-subtype difference in self-esteem. In the EMA data, anger toward others, feeling of rejection, loneliness, and helplessness were significantly high in the substance abuse and suicide attempt subtype. The variability of anger toward others was also higher in this subtype compared to the cutting and scratching subtype. Finally, in the two-week research period, the substance abuse and suicide attempt group showed a higher rate of reported urges to self-harm with or without suicidal intent.

CONCLUSION

Findings support the validity of the subtypes based on the forms of self-harm behavior, suggesting the clinical utility of addressing heterogeneity within individuals exhibiting self-harm for assessment and treatment.

Non-suicidal self-injury and its relation to suicide through acquired capability: investigating this causal mechanism in a mainly late-diagnosed autistic sample

BACKGROUND

Non-suicidal self-injury (NSSI) has been linked with a higher risk of suicide attempts in autistic and non-autistic people. In the general population, NSSI may confer acquired capability for suicide by eroding one's fear and avoidance of pain and death. The present study aimed to explore acquired capability as the mediator of increased suicide risk conferred by NSSI in autistic and non-autistic adults.

METHODS

Autistic and non-autistic adults (n = 314, n = 312) completed an online survey exploring lifetime suicide attempts, experience with NSSI, and acquired capability for suicide. We explored relationships between lifetime incidence of NSSI and lifetime suicide attempts via three facets of acquired capability (pain tolerance, reduced fear of death, and mental rehearsal of suicide). In self-harming participants (224 autistic and 156 non-autistic), we explored whether particular types and features of NSSI might be especially associated with capability and through that with suicide: namely engagement in scratching, cutting, and self-hitting, and engaging in more numerous forms of NSSI.

RESULTS

While a higher frequency of NSSI was associated with all three facets of acquired capability, only reduced fear of death and mental rehearsal of suicide mediated an indirect relationship with lifetime suicide attempts. NSSI also directly predicted more numerous suicide attempts. Autistic people tended towards reduced fear of death and mental rehearsal regardless of NSSI status. Among self-harming autistic and non-autistic participants, cutting and an increased number of NSSI behaviours were associated with lifetime suicide attempts directly and indirectly via acquired capability. In both groups, self-hitting was associated with lifetime suicide attempts only via acquired capability.

LIMITATIONS

Our cross-sectional methodology negates inferences of directionality. While we controlled for age, our samples were poorly matched, with the autistic group two times older on average. The autistic sample, predominantly late-diagnosed, female and highly qualified, were unrepresentative of the whole autistic community.

CONCLUSIONS

Our data suggest that acquired capability, as measured herein, is an incomplete explanation for the association between NSSI and suicide risk. A broader construct with stable and transient facets may offer greater explanatory power, but it is probable that other variables explain or provide additional means through which this association arises.

Screening for borderline personality pathology on college campuses

Although borderline symptoms show a normative decline throughout adulthood, severe psychosocial impairment often remains. Identifying personality pathology in college-age students may help prevent "adaptive failure" that can occur during the critical period of development from puberty through the late 20s and thus reduce impairment later in life. The aims of the current study were to estimate the prevalence of borderline personality disorder (BPD) in a diverse college sample, determine which symptoms confer the greatest relative risk of screening positive for BPD and examine the utility of the Personality Inventory for DSM-5 brief form (PID-5-BF) in identifying BPD. Participants were 1456 undergraduate students, and 312 individuals (21.4% of the sample) screened positive for BPD. Chronic feelings of emptiness conferred the greatest relative risk of any symptom; students who endorsed this symptom were 15 times more likely to screen positive for BPD than those who did not. Scales and composite scores of the PID-5-BF demonstrated diagnostic accuracy ranging from sufficient to excellent. The current study contributes to literature concerning best practices in screening for personality pathology in young adults. Results suggest that chronic feelings of emptiness are significant for detecting at-risk students and implications for the use of the PID-5-BF are discussed.

Self-injury motives: A person-centered examination

INTRODUCTION

People report multiple motives for nonsuicidal self-injury (NSSI), but few studies have examined how these motives relate to one another. This study identified person-centered classes of NSSI motives, their NSSI and psychopathological correlates, and their utility in predicting future NSSI across two samples.

METHODS

Participants were adolescents and young adults (aged 15-35) with recent NSSI recruited from online forums (n = 155, Sample 1) or the community (n = 127, Sample 2). Participants completed measures of NSSI, emotion regulation difficulties, borderline personality disorder (BPD), depression, and reported on their NSSI over 12 months.

RESULTS

Latent profile analyses yielded five classes in each sample: low interpersonal, self-punishment/interpersonal, moderate intra/interpersonal, high intra/interpersonal, and mainly interpersonal motives. Classes were not associated with lifetime NSSI characteristics, but highly motivated participants reported more severe depression and BPD symptoms, and greater emotion dysregulation than low-motivated participants. Those in the mainly interpersonal (Sample 1) and self-punishment/interpersonal (Sample 2) motives classes reported greater NSSI frequency during follow-up.

CONCLUSIONS

This study identified five classes of NSSI motives. Participants who report multiple motives for NSSI may be more clinically severe, whereas those who report strong desires to communicate with others or punish themselves may be at the highest risk for more frequent NSSI over time.

Understanding predictors of change in a day treatment setting for non-suicidal self-injury

OBJECTIVES

To examine change in non-suicidal self-injury (NSSI) frequency, quality of life, and functional impairment from admission to discharge in patients enrolled in partial hospitalization and intensive outpatient programmes (PHP/IOP) designed to treat NSSI. Demographic, clinical, and treatment-related predictors of changes were also examined.

DESIGN

Data were collected as part of routine clinical assessment procedures at admission and discharge from patients enrolled in a PHP/IOP programme designed to treat NSSI. The clinical assessment included measures examining quality of life, functional impairment, and NSSI behaviour.

METHODS

Paired t-tests were used to examine change in NSSI frequency, quality of life, and functional impairment. Reliable clinical change analyses were used to identify clinically significant change in quality of life and functional impairment. Multilevel mixed-effects regression was used to examine predictors of change for quality of life and functional impairment. Negative binomial regression was used to examine predictors of change for NSSI frequency.

RESULTS

From admission to discharge, NSSI frequency significantly decreased and quality of life and functional impairment evidenced clinically significant change. Age, race/ethnicity, and insurance type predicted change in functional impairment, while gender predicted change in quality of life. Urge to self-injure predicted change in NSSI frequency. Borderline symptoms predicted change across all outcome variables.

CONCLUSIONS

Patients who completed a day treatment programme for NSSI evidenced significant change in NSSI frequency, functional impairment, and quality of life at discharge; however, several demographic and clinical variables were associated with change.

PRACTITIONER POINTS

Patients who engage in NSSI show significant change from admission to discharge in a day treatment programme dedicated to the treatment of NSSI. Quality of life and functional impairment are important outcome variables to consider and evaluate in higher levels of care. It is important to consider demographic and clinical variables when creating a treatment plan for NSSI. Although BPD symptoms may be important to consider in day treatment for NSSI, interpersonal dysfunction, depressive symptoms, and mood lability may also affect change in symptoms.

Pain sensitivity and plasma beta-endorphin in adolescent non-suicidal self-injury

BACKGROUND

Beta-endorphin (BE) has been suggested to play a central role as to why people engage in NSSI. To our knowledge, no study has systematically assessed this potential relationship in adolescents with NSSI.

METHODS

94 adolescents with NSSI (according to DSM-5 criteria) and 35 healthy controls (HC) were enrolled. All participants received heat pain stimulation, with pain threshold and tolerance measured in °C. Plasma BE levels were assessed. Sociodemographic and clinical characteristics were obtained via semi-structured interviews and self-report questionnaires.

RESULTS

Adolescents with NSSI showed increased pain thresholds (t₍₁₂₇₎=2.071, p=.040), lower pain intensity (t₍₁₁₄₎==2.122, p=.036) and lower plasma BE levels (t₁₂₇==3.182, p=.002) compared to HC. Groups did not differ on pain tolerance (t₍₁₂₇₎=0.911, p=.364). Greater pain threshold correlated positively with borderline personality disorder (BPD) symptoms (r=0.182, p=.039), while pain intensity (r=-0.206, p=.033) and BE levels (r=-0.246, p=.007) correlated negatively with depression severity. No significant relationship was found between pain threshold and plasma BE (r=-0.013, p=.882).

LIMITATIONS

Future studies should implement repeated plasma BE measures to assess BE release in association with pain in NSSI. Validity of plasma BE measures compared to central measures should be considered. Assessing the association between pain sensitivity (PS) and BE in a naturalistic setting presents a promising avenue for future research in NSSI.

CONCLUSIONS

Findings support both reduced PS and basal opioid deficiency as independent biological correlates and potential risk-factors for NSSI. Further longitudinal and experimental studies are needed to investigate the role of BE levels and PS as well as their potential association.

Moderators of treatment response to an intervention for nonsuicidal self-injury in young adults

Objective: Despite the prevalence and impact of nonsuicidal self-injury (NSSI), there are few treatments developed to treat the behavior specifically, and little is known about moderators of treatment response. The Treatment for Self-Injurious Behaviors (T-SIB), a brief, behavioral intervention, was developed to treat NSSI in young adults; a previous pilot randomized controlled trial (RCT) comparing T-SIB with treatment as usual (TAU) provided support for the intervention. This study examined demographic, clinical, and NSSI-related predictors of treatment outcome in the pilot RCT for T-SIB. Method: Young adults (N = 33) were randomized to receive T-SIB or treatment as usual; all participants were included in intent-to-treat analyses. The primary outcome of NSSI behaviors was assessed at baseline, posttreatment (9 weeks), and 3-month follow up, and potential moderators were assessed at baseline. Results: Greater lifetime and last year NSSI frequency was associated with fewer NSSI behaviors at posttreatment and follow up among participants in T-SIB. Anxious symptoms also moderated treatment outcomes, but other demographic and clinical variables did not. Conclusion: Previous research has shown that T-SIB is more effective than TAU overall; the current study suggests that T-SIB may be effective for individuals with more frequent NSSI and those with elevated anxiety. A larger evaluation of T-SIB is supported. (PsycInfo Database Record (c) 2020 APA, all rights reserved).

Using an ideal observer analysis to investigate the visual perceptual efficiency of individuals with a history of non-suicidal self-injury when identifying emotional expressions

Individuals who engage in non-suicidal self-injury (NSSI) often report significant interpersonal difficulties, with studies lending support to the idea of impaired social interactions. Perceptual processing deficits of facial expressions have also been associated with interpersonal difficulties, yet little research has assessed how individuals with a history of NSSI (HNSSI) process facial emotions. This study used an ideal observer analysis to assess emotion processing capabilities of these individuals. A total of 30 HNSSI and 31 controls were presented with static images of various facial expressions (fear, anger, disgust, happiness, sadness, surprise) at three intensity levels (50%, 75% and 100% emotion expressivity). Recognition of emotions were measured by signal-proportion thresholds, efficiency scores, and unbiased hit rate. Error responses were also recorded to investigate errors biases made by each group. No significant differences between HNSSI and controls were found in signal-proportion thresholds or efficiency scores. Decreased accuracy of HNSSI participants for recognizing fearful expressions was observed. An increased likelihood of mistaking angry for happy expressions and a decreased likelihood of mistaking sad for surprised expressions were recorded for the HNSSI group compared to controls. These findings provide support to the literature reporting deficits in accurate emotion identification for those engaged in NSSI behaviours.

Nonsuicidal Self-Injury and Suicide: Differences Between Those With and Without Borderline Personality Disorder

Nonsuicidal self-injury (NSSI) is associated with borderline personality disorder (BPD), but it also occurs in nonclinical samples (Briere & Gil, 1998), inflicting serious harm and serving as a precursor to suicide attempts (Klonsky, May, & Glenn, 2013). Therefore, the DSM-5 proposed a nonsuicidal self-injury disorder (NSSID) and suicidal behavior disorder. Because this addition requires reconciliation with current BPD criteria, the authors' study evaluated type and frequency of NSSI and suicide attempts in 3,795 outpatients. Both were found in those without BPD, although the behaviors increased when some symptoms and full criteria for BPD were met. Wound/skin picking, scratching, and hitting were most common. Cutting was the fifth most common self-injury for those with BPD and the eighth most common for those without the disorder. Therefore, increased clinical attention is warranted for such self-injury, which may go unnoticed but indicate significant distress. Findings suggest that NSSID/suicidal behavior disorder may account for self-injury outside of BPD.

Getting Specific about Emotion and Self-Inflicted Injury: An Examination Across Emotion Processes in Borderline Personality Disorder

This study aimed to examine which specific emotion processes influence self-inflicted injury: basal respiratory sinus arrhythmia, baseline negative emotional intensity, emotional reactivity, or emotion regulation deficits. Self-injuring individuals with borderline personality disorder (N = 22) reported their lifetime self-injury frequency. Basal respiratory sinus arrhythmia and baseline skin conductance responses measurements were collected. Participants then either reacted as they usually would (i.e., emotional reactivity), or utilized mindfulness- or distraction-based strategies (i.e., emotion regulation), in response to negative images while self-reported negative emotion and skin conductance were monitored. Higher basal respiratory sinus arrhythmia and baseline emotional intensity predicted higher lifetime self-injury frequency. Chronic, resting emotion processes may be more important targets for reducing self-injury compared to labile, acute emotion processes.

Emotion dysregulation and non-suicidal self-injury: A systematic review and meta-analysis

BACKGROUND

Over the past several years there has been considerable interest in the relation between emotion dysregulation and non-suicidal self-injury (NSSI), particularly given that rates of NSSI have been increasing and NSSI is a critical risk factor for suicidal behavior. To date, however, no synthesis of empirical findings exists.

METHODS

The present study presents a comprehensive meta-analytic review of the literature on the association between NSSI and emotion dysregulation. A total of 48 publications, including 49 independent samples, were included in this analysis.

RESULTS

Overall, a significant association was found between emotion dysregulation and NSSI (pooled OR = 3.03 [95% CI = 2.56-3.59]). This association was reduced but remained significant (OR = 2.40 [95% CI = 2.01-2.86]) after adjustment for publication bias. Emotion dysregulation subscales most strongly associated with NSSI included limited access to regulation strategies, non-acceptance of emotional responses, impulse control difficulties, and difficulties engaging goal-directed behavior. Lack of emotional awareness/clarity and cognitive aspects of dysregulation yielded weaker, yet significant, positive associations with NSSI.

CONCLUSIONS

Findings support the notion that greater emotion dysregulation is associated with higher risk for NSSI among individuals across settings, regardless of age or sex. Furthermore, findings reveal facets of dysregulation that may have unique implications for NSSI. This meta-analysis highlights the importance of better understanding emotion dysregulation as a treatment target for preventing NSSI.

The unique contribution of acceptance without judgment in predicting nonsuicidal self-injury after 20-weeks of dialectical behaviour therapy group skills training

The current research tested whether four dimensions of mindfulness - acceptance without judgment, observing, describing and acting with awareness - predicted frequency of nonsuicidal self-injury (NSSI) and mediate the relationship with NSSI outcomes during 20-weeks of Dialectical Behaviour Therapy (DBT) skills training for borderline personality disorder (BPD). Eighty-four self-harming individuals with BPD were randomized to either DBT skills training or to a waitlist control group. A series of regressions revealed no relationship between dimensions of mindfulness and NSSI at baseline. There was a significant effect of DBT skills training on NSSI. As well, mediation analysis indicated that acceptance without judgment, specifically, mediated the relation between DBT skills training and change in frequency of NSSI.

Exploring the relationship between non suicidal self-injury and borderline personality traits in young adults

Non-suicidal self-injury (NSSI) is highly prevalent during late adolescence and young adulthood. There is some evidence of a link between NSSI and Borderline Personality Disorder (BPD), but little is known about the association between BPD traits and the various functions that maintain NSSI. The main purpose of this study was to explore the association between borderline personality traits and NSSI functions in a sample of college students. We also compared NSSI functions in college students who engaged in NSSI to those in an age-matched sample of BPD patients. This study included a total of 238 college students and 36 BPD patients. Participants were asked to complete a number of clinical measures. In the non-clinical sample, BPD features were more pronounced in the presence of NSSI, and we observed a differential relationship between NSSI functions and psychopathological BPD-traits. The NSSI clinical variables most strongly associated with BPD were frequency, variety of methods and severity, but not age of onset. Our results provide new information on the relationship between BPD and NSSI in young adults, and could be used to improve the early detection of vulnerable BPD-individuals and in planning NSSI treatment.

Nonsuicidal Self-Injury in Adolescents: Characterization of the Disorder and the Issue of Distress and Impairment

Nonsuicidal self-injury disorder (NSSID) is a condition in need of further study to assess the validity of the potential diagnosis and its suggested criteria. This study examined the NSSID diagnosis and investigated the distress/impairment criterion by comparing community adolescents who met all criteria for NSSID (n = 186) to adolescents with five or more nonsuicidal self-injury (NSSI) episodes (n = 314), and to a group of adolescents who met all criteria but negated that their NSSI caused them any distress or impairment, thus failing to meet criterion E (n = 29). The NSSID group delimited from the ≥ 5 NSSI group by reporting significantly more frequent and severe self-injurious thoughts and behaviors, as well as having more experiences of negative life events and higher levels of trauma symptoms. There were also some differences between the NSSID group and adolescents without distress/impairment, which together contribute valuable information on the potential NSSID diagnosis, as well as the discussion of criterion E.

An intervention for nonsuicidal self-injury in young adults: A pilot randomized controlled trial

OBJECTIVE

Nonsuicidal self-injury (NSSI) is prevalent among young adults and associated with negative medical and psychological consequences, necessitating its treatment. However, few treatments have been developed to treat NSSI specifically, or to treat the behavior among individuals without borderline personality disorder. The purpose of this study was to investigate the Treatment for Self-Injurious Behaviors (T-SIB), a brief, behavioral intervention specifically developed to treat NSSI among young adults, in a pilot randomized controlled trial (RCT).

METHOD

Young adults (N = 33; age: M = 22.36 years, SD = 3.40) meeting inclusion and exclusion criteria were randomly assigned to the treatment (T-SIB; n = 15) or treatment as usual (n = 18) condition. The sample was 93.9% female, 42.4% Caucasian, and 30.3% Hispanic/Latino.

RESULTS

Feasibility and acceptability of the study and intervention were supported, and medium effects were found for decreased NSSI frequency in the T-SIB group using intent-to-treat analyses.

CONCLUSION

Results of this study support the further evaluation of T-SIB in a larger RCT. (PsycINFO Database Record

Descriptive Characteristics and Initial Psychometric Properties of the Non-Suicidal Self-Injury Disorder Scale

Non-suicidal self-injury (NSSI) is highly prevalent and associated with tissue damage, emotional distress, and psychiatric disorders. While often discussed in the context of Borderline Personality Disorder and suicide, research demonstrates that NSSI is distinct from these constructs and should be viewed as an independent diagnostic category. Recently, Non-Suicidal Self-Injury Disorder (NSSID) was included in the revised Diagnostic and Statistical Manual of Mental Disorders as a condition for further study. In this article, we describe the properties of a self-report measure designed to assess proposed criteria for NSSID. Undergraduate students at 2 large, public universities completed the NSSID Scale (NSSIDS) along with other measures of NSSI characteristics and psychopathology. Among participants with a history of NSSI, approximately half (54.55%) met diagnostic criteria for NSSID. Participants were most frequently excluded from an NSSID diagnosis on the basis of criterion A (frequency of NSSI) and criterion E (distress or impairment related to NSSI), while participants were least likely to be excluded from diagnosis on the basis of criterion D (NSSI method exclusions) and criterion F (diagnostic "rule-outs"). Consistent with previous literature, the most commonly reported precipitants to NSSI were negative feelings or thoughts (criterion C2). Participants who met criteria for NSSID reported more severe depression, anxiety, and NSSI than participants who engaged in NSSI but did not meet criteria for NSSID. These results support the use of the NSSIDS as a reliable and valid self-report measure of NSSID symptoms.

The influence of personality traits and emotional and behavioral problems on repetitive nonsuicidal self-injury in a school sample

BACKGROUND

Nonsuicidal self-injury (NSSI) is highly prevalent among adolescents and associated with various mental health problems and suicidality. Previous studies have found that certain personality traits are related to NSSI behavior, however only few studies examined personality traits in adolescents with NSSI. Our study aimed to assess the relationship between personality traits and emotional and behavioral problems in predicting repetitive NSSI among adolescents from a school sample.

METHODS

Four hundred and forty-seven students (M=14.95years, SD=0.74, 52% male) completed self-report measures on NSSI, personality traits, and emotional and behavioral problems.

RESULTS

The past year prevalence of occasional and repetitive NSSI was 4.9% and 6.3% respectively. Repetitive NSSI was significantly associated with female gender, higher levels of age, novelty seeking, harm avoidance, self-transcendence, antisocial behavior, and positive self and lower levels of persistence and self-directedness in univariate analyses. However, multivariate logistic regression analyses indicated that only high levels of antisocial behavior and low levels of self-directedness significantly predicted repetitive NSSI.

CONCLUSIONS

The association between a lack of self-directedness and NSSI emphasizes the significance of targeting self-directedness in psychotherapy by strengthening self-awareness, affect tolerance and emotion regulation, as well as establishing and pursuing long-term goals.

Temperament and character traits in female adolescents with nonsuicidal self-injury disorder with and without comorbid borderline personality disorder

BACKGROUND

Temperament and character traits of adolescents with nonsuicidal self-injury disorder (NSSI) might differentiate those- with and without comorbid borderline personality disorder (BPD).

METHODS

Participants were 57 female adolescents with NSSI disorder without BPD (NSSI - BPD), 14 adolescents with NSSI disorder and BPD (NSSI + BPD), 32 clinical controls (CC), and 64 nonclinical controls (NC). Temperament and character traits were assessed with the Junior Temperament and Character Inventory, and impulsivity with the Barratt Impulsiveness Scale and a Go/NoGo task.

RESULTS

Adolescents with NSSI disorder scored significantly higher on novelty seeking and harm avoidance and lower on persistence, self-directedness, and cooperativeness than CC. The NSSI + BPD group scored even higher than the NSSI - BPD group on novelty seeking and harm avoidance and lower on persistence and cooperativeness (d ≥ 0.72). Adolescents with NSSI reported higher levels of impulsivity than the CC and NC group. However, this difference was not found in a Go/NoGo task.

CONCLUSIONS

The results provide further evidence for a distinct diagnostic entity of NSSI disorder.

Diagnostik und Behandlung nichtsuizidaler Selbstverletzungen im Kindes- und Jugendalter

Zusammenfassung. Theoretischer Hintergrund: Nichtsuizidales Selbstverletzendes Verhalten (NSSV) ist insbesondere im Jugendalter häufig und klinisch bedeutsam. Die Entwicklung einer konsensbasierten Leitlinie verfolgt das Ziel, die Diagnostik und die Behandlung von NSSV zu optimieren und Impulse für die Forschung zu geben. Als Leitlinie der Arbeitsgemeinschaft der Wissenschaftlichen Medizinischen Gesellschaften (AWMF) wurde diese erste Leitlinie zu NSSV verabschiedet und publiziert. Fragestellung und Methode: Die wichtigsten Empfehlungen zur Diagnostik und Behandlung von NSSV werden zusammengefasst und Forschungslücken aufgezeigt. Ergebnisse: In der Diagnostik von NSSV ist insbesondere die Einschätzung der Suizidalität zu berücksichtigen. Als erster Schritt ist die somatische Abklärung der Verletzungen und ggf. eine medizinische Erstversorgung zu nennen. Für die Evaluation des NSSV sind Häufigkeit, Methoden, Schmerzempfinden, Motive, Impulsivität als auch weitere familiäre und außerfamiliäre Einflussfaktoren zu erheben. Den Schwerpunkt der Behandlung bildet die Psychotherapie, insbesondere die kognitive Verhaltenstherapie, die Dialektisch-Behaviorale Therapie für Adoleszente und die Mentalisierungsbasierte Therapie für Adoleszente. Eine evidenzbasierte Indikation zur spezifischen Pharmakotherapie von NSSV existiert nicht. Schlussfolgerung: Die Leitlinie umfasst evidenz- und konsensusbasierte Empfehlungen zur Diagnostik und Therapie von NSSV. Die Implementierung soll zu einer Verbesserung der Versorgung von Patienten mit NSSV dienen.

Health related quality of life and psychopathological distress in risk taking and self-harming adolescents with full-syndrome, subthreshold and without borderline personality disorder: rethinking the clinical cut-off?

BACKGROUND

Diagnostic standards do not acknowledge developmental specifics and differences in the clinical presentation of adolescents with borderline personality disorder (BPD). BPD is associated with severe impairments in health related quality of life (HRQoL) and increased psychopathological distress. Previously no study addressed differences in HRQoL and psychopathology in adolescents with subthreshold and full-syndrome BPD as well as adolescents at-risk for the development but no current BPD.

METHODS

Drawing on data from a consecutive sample of N = 264 adolescents (12-17 years) presenting with risk-taking and self-harming behavior at a specialized outpatient clinic, we investigated differences in HRQoL (KIDSCREEN-52) and psychopathological distress (SCL-90-R) comparing adolescents with no BPD (less than 3 criteria fulfilled), to those with subthreshold (3-4 BPD criteria) and full-syndrome BPD (5 or more BPD criteria). Group differences were analyzed using one-way analysis of variance with Sidak corrected contrasts or Chi-Square test for categorical variables.

RESULTS

Adolescents with subthreshold and full-syndrome BPD presented one year later at our clinic and were more likely female. Adolescents with subthreshold and full-syndrome BPD showed greater Axis-I and Axis-II comorbidity compared to adolescents with no BPD, and reported greater risk-taking behaviour, self-injury and suicidality. Compared to those without BPD, adolescents with subthreshold and full-syndrome BPD reported significantly reduced HRQoL. Adolescents with sub-threshold BPD and those with full-syndrome BPD did not differ on any HRQoL dimension, with the exception of Self-Perception. Similar, groups with sub-threshold and full-syndrome BPD showed no significant differences on any dimension of self-reported psychopathological distress, with the exception of Hostility.

CONCLUSIONS

Findings highlight that subthreshold BPD in adolescents is associated with impairments in HRQoL and psychopathological distress comparable to full-syndrome BPD. Findings raise awareness on the importance of early detection and question the diagnostic validity and clinical utility of existing cut-offs. Findings support a lower diagnostic cut-off for adolescent BPD, to identify those at-risk at an early stage.

Reasons for Non-Suicidal Self-Harm in Adult Male Offenders With and Without Borderline Personality Traits

The presented study aimed to advance understanding of the reasons for non-suicidal self-harm (NSSH) in adult male offenders, with and without borderline personality traits. 179 offenders completed self-report measures of NSSH and other clinical constructs, with 42 being identified as having self-harmed. Results were consistent with past research and supported the relative importance of intrapersonal over interpersonal functions, but also highlight that self-harm is performed rarely for one type of reason. The results also show that the presence of borderline personality traits increases the likelihood of endorsing a range of interpersonal reasons. These findings highlight the importance of understanding the range of reasons for engaging in NSSH to help manage the behaviour within the prison.

A meta-analysis on pain sensitivity in self-injury

Individuals engaging in self-injurious behavior (SIB) frequently report absence of pain during acts of SIB. While altered pain sensitivity is discussed as a risk factor for the engagement in SIB, results have been mixed with considerable variance across reported effect sizes, in particular with respect to the effect of co-morbid psychopathology. The present meta-analysis aimed to summarize the current evidence on pain sensitivity in individuals engaging in SIB and to identify covariates of altered pain processing. Three databases were searched without restrictions. Additionally a hand search was performed and reference lists of included studies were checked for potential studies eligible for inclusion. Thirty-two studies were identified after screening 720 abstracts by two independent reviewers. Studies were included if they reported (i) an empirical investigation, in (ii) humans, including a sample of individuals engaging in (iii) SIB and a group of (iv) healthy controls, (v) receiving painful stimulation. Random-effects meta-analysis was performed on three pain-related outcomes (pain threshold, pain tolerance, pain intensity) and several population- and study-level covariates (i.e. age, sex, clinical etiology) were subjected to meta-regression. Meta-analysis revealed significant main effects associated with medium to large effect sizes for all included outcomes. Individuals engaging in SIB show greater pain threshold and tolerance and report less pain intensity compared to healthy controls. Clinical etiology and age are significant covariates of pain sensitivity in individuals engaging in SIB, such that pain threshold is further increased in borderline personality disorder compared to non-suicidal self-injury. Mechanisms underlying altered pain sensitivity are discussed.

Predictors for DSM-5 nonsuicidal self-injury in female adolescent inpatients: The role of childhood maltreatment, alexithymia, and dissociation

The purpose of this study was to examine the relationship between various adverse childhood experiences, alexithymia, and dissociation in predicting nonsuicidal self-injury (NSSI) in an inpatient sample of female adolescents. Seventy-two adolescents (aged 14-18 years) with NSSI disorder (n=46) or mental disorders without NSSI (n=26) completed diagnostic interviews and self-report measures to assess NSSI disorder according to the DSM-5 criteria, childhood maltreatment, alexithymia, and dissociation. Alexithymia and dissociation were highly prevalent in both study groups. Multivariate logistic regression analyses indicated that only alexithymia was a significant predictor for NSSI, whereas childhood maltreatment and dissociation had no predictive influence. The association between alexithymia and NSSI emphasizes the significance of emotion regulation training for female adolescents with NSSI. Efforts to reduce NSSI behavior should therefore foster skills to heighten the perception and recognition of one's own emotions.

[Emotion Regulation in Adolescents with Nonsuicidal Self-Injury]

Nonsuicidal self-injury (NSSI) is a prevalent and impairing condition that was newly included in DSM-5 in the section III criteria for further research. Difficulties in emotion regulation play an important role in the development and maintenance of NSSI. This study investigated the emotion regulation in female adolescents with NSSI according to DSM-5 (n=55), clinical control adolescents with mental disorders without NSSI (n=30), and nonclinical control adolescents (n=58) using self-report questionnaires and interviews. As expected, results indicated that adolescents with NSSI have significantly more difficulties in emotion regulation compared to healthy controls. In addition, adolescents with NSSI reported also significantly more difficulties in impulse control, lack of emotional clarity, difficulties engaging in goal-directed behavior, and limited access to emotion regulation strategies compared to nonclinical and clinical controls. Adolescents with NSSI felt significantly more often sadness compared to clinical controls (d=0.66) and compared to other emotions. Adolescents with NSSI indicated significantly less often happiness compared to nonclinical controls (d=1.83). Results support that adolescents with NSSI have difficulties in emotion regulation and that these difficulties are even more pronounced than in adolescents with other mental disorders. Clinical implications will be discussed.

Non-suicidal self-injury with and without borderline personality disorder: differences in self-injury and diagnostic comorbidity

Although non-suicidal self-injury (NSSI) occurs in people with and without borderline personality disorder (BPD), few studies have compared the clinical characteristics of these two groups. The present study sampled adults with a history of NSSI and compared those with and without BPD on (a) NSSI features, (b) co-occurring psychiatric disorders, and (c) severity of depression, suicidal ideation and emotion dysregulation. Participants (NSSI+BPD, n=46; NSSI Only, n=54) completed semi-structured interviews and self-report measures. Whereas the groups did not differ in age of NSSI onset, the NSSI+BPD group engaged in more frequent, recent and severe NSSI, and reported higher rates of skin carving, head banging, self-punching and self-scratching than the NSSI Only group. Participants with BPD also showed greater diagnostic comorbidity, particularly for anxiety disorders, but did not differ from participants without BPD in rates of mood, substance or psychotic disorders. The NSSI+BPD group reported more severe depressive symptomatology, suicidal ideation and emotion dysregulation than the NSSI Only group. Supplementary analyses on the subset of participants with recent (past year) NSSI revealed similarly medium to large differences between those with and without BPD. Implications for assessment and treatment are discussed.

The DSM-5 diagnosis of nonsuicidal self-injury disorder: a review of the empirical literature

With the presentation of nonsuicidal self-injury disorder (NSSID) criteria in the fifth version of the Statistical and Diagnostic Manual of Mental Disorders (DSM-5), empirical studies have emerged where the criteria have been operationalized on samples of children, adolescents and young adults. Since NSSID is a condition in need of further study, empirical data are crucial at this stage in order to gather information on the suggested criteria concerning prevalence rates, characteristics, clinical correlates and potential independence of the disorder. A review was conducted based on published peer-reviewed empirical studies of the DSM-5 NSSID criteria up to May 16, 2015. When the DSM-5 criteria were operationalized on both clinical and community samples, a sample of individuals was identified that had more general psychopathology and impairment than clinical controls as well as those with NSSI not meeting criteria for NSSID. Across all studies interpersonal difficulties or negative state preceding NSSI was highly endorsed by participants, while the distress or impairment criterion tended to have a lower endorsement. Results showed preliminary support for a distinct and independent NSSID diagnosis, but additional empirical data are needed with direct and structured assessment of the final DSM-5 criteria in order to reliably assess and validate a potential diagnosis of NSSID.

Facial emotion recognition in adolescents with nonsuicidal self-injury

Adolescents with nonsuicidal self-injury (NSSI) have been described as having considerable impairment in social interactions, and social difficulties are often a trigger for NSSI. However, little is known about how adolescents with NSSI disorder process facial expressions of emotion. We investigated the recognition of facial expressions of emotion in 47 adolescents with NSSI disorder, 28 clinical controls without NSSI, and 51 nonclinical controls. Following a neutral or a sad mood induction, participants were presented with a dynamic facial expression that slowly changed from neutral to full-intensity happiness, sadness, anger, disgust, fear or neutral (closed/open mouth). Recognition of facial expressions was measured by the intensity of the expression at which participants could accurately identify the facial expression. No group differences in the recognition of facial expressions were found. All groups required comparable stages of emotional expressivity to correctly recognize emotions, and there were no significant differences in accuracy. Results indicate no mood effect on recognition or accuracy. Valence and arousal ratings of stimuli indicated that compared to the nonclinical control group but not to clinical controls, the adolescents with NSSI disorder rated the stimuli as significantly more unpleasant and arousing.

Nonsuicidal Self-Injury in Adolescents

Abstract. Nonsuicidal self-injury (NSSI) is a prevalent, pervasive, clinically significant behavior in adolescents, frequently associated with serious social, physical, and psychological consequences. It is characterized by high comorbidity with various disorders. Therefore, NSSI has been included as a research diagnosis in the Diagnostic and statistical manual of mental disorders (5th ed., American Psychiatric Association (APA; 2013) ; DSM-5; Section 3), as a condition requiring further study for possible future official adoption. This is a positive step toward providing researchers with a uniform definition and criteria. This state-of-the-art article gives an overview of prevalence rates, comorbidity, clinical correlates, functions, and risk factors as well as treatment and dealing with adolescents with NSSI and their Internet activities. Furthermore, the association and differences between NSSI and suicidality as well as borderline personality disorder are reviewed. The article concludes with future directions for research, for example, the dimensional approach to classification of the Research Domain Criteria project.

Comparative analysis of self-injury in people with psychopathology or neurodevelopmental disorders

Self-injury is a complex and poorly understood behavior observed in people with psychopathology or neurodevelopmental disorders (NDD). Despite the differences in etiology and progression of these distinct disease domains, it is possible that overlapping molecular pathways underlie the expression of self-injurious behaviors (SIBs). This review outlines the similarities and differences at the behavioural and molecular level, where SIBs in both conditions may involve opioid, nucleoside, and dopamine signalling. These points of convergence have important implications for treatment and research of SIB in both populations.
