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

Average ages of onset and time to transition between self-injurious thoughts and behaviors: Retrospective evidence from two developmentally distinct samples

BACKGROUND

Suicidal thoughts and behaviors often emerge in a predictable sequence, with suicidal ideation (SI) preceding planning, and planning preceding actions. Few studies, however, have considered the timing and duration of non-suicidal self-injury (NSSI) in these transitions. Accordingly, this study examined: 1) the developmental sequencing of NSSI, SI and suicide attempts, and 2) whether age of onset or duration predict transitions from NSSI to other SITB, and from SI to NSSI.

METHODS

704 first-year students from a mid-sized Canadian university (Sample 1) and 2095 adults from an online research volunteer panel (Sample 2) completed the Self-Injurious Thoughts and Behaviors Interview self-report, which assessed the presence, age of onset, and recency of SITB.

RESULTS

NSSI and SI typically onset before age 15, while suicide planning and attempt usually began at or after age 15. Transition from NSSI to SI was likeliest in the first year after NSSI onset. Transition from NSSI to suicide attempt was likeliest in the second and third year after NSSI onset in Sample 1, and up to four years after NSSI onset in Sample 2. Early (before age 13) and late (after age 16) onsets of NSSI predicted higher odds of transitioning from NSSI to SI or attempt. Transition from SI to NSSI was likeliest in the first two years after SI onset and when SI began before age 13.

CONCLUSIONS

The first year after NSSI or SI onset are critical for transitions to other SITB. Targeted prevention and monitoring should be considered for people who recently initiated NSSI.

Functions of nonsuicidal self-injury and repeated nonsuicidal self-injury among adolescents: A moderating role of addictive features

OBJECTIVE

The high prevalence and addictive features of nonsuicidal self-injury (NSSI) in adolescents have been documented, but the role of addictive features in the process from NSSI functions to behaviour remains unclear. The major aim of this study was to investigate the effect of addictive features on NSSI functions and the severity of repeated NSSI.

METHODS

A total of 10,781 students from primary and middle schools in Chengdu and Karamay were invited to participate in the online cross-sectional survey, and 10,501 completed the survey. Two self-report questionnaires, the Ottawa Self-Injury Inventory (OSI) and the Adolescent Self-Harm Scale (ASHS), were used to collect data from all participants.

RESULTS

Among the students, 23.45% and 6.64% reported having engaged in NSSI at least once or at least five times in the past year. Being a girl, being an only child, and being in a single-parent family were significantly associated with more severe NSSI. Addictive features have high value for predicting repeated NSSI. In addition to their significant independent/direct additive effects, addictive features mediated and moderated the relationship between NSSI functions and increased severity of NSSI in adolescents.

DISCUSSION AND CONCLUSIONS

The findings suggest that addictive features play a critical role in the development of repeated NSSI in adolescents, which indicates that addiction models may partially explain the mechanism underlying increased severity of NSSI. This may enhance understanding of the reasons for repeated NSSI and inform interventions for repeated NSSI among adolescents.

You're not alone: imagery rescripting for adolescents who self-harm

Introduction

Non-suicidal self-injury (NSSI), which refers to the deliberate act of causing harm to one's own body without the intent to commit suicide, occurs in 20% of youth. Interestingly, approximately 90% of individuals who engage in self-harm report intrusive mental imagery thereof shortly prior to the act of NSSI. Previous research has demonstrated that imagery rescripting (IR) is an effective technique to treat intrusive mental images and associated clinical symptoms, such as emotion dysregulation, in various psychiatric disorders. However, there is no research on IR for adolescents who self-harm. Therefore, the present study aims to investigate the efficacy and feasibility of a two-session short-intervention using IR to reduce NSSI and associated clinical symptoms in adolescents. The intervention was supported by an app-based digital health intervention (DHI).

Methods

A single case series A-B design with three post-assessments (1 week, 1 month, and 3 months post-intervention) was implemented. Seven adolescents received two treatment sessions of IR, supported by a DHI between sessions. NSSI (SITBI), emotion regulation (ERQ), emotional distress (BDI-II, STAI-T), self-efficacy (WIRKALL_r), and treatment satisfaction (BIKEP) were evaluated.

Results

There was an increase in adaptive emotion regulation strategies up to 3 months post-intervention. Furthermore, patients improved regarding their self-efficacy, depressiveness, anxiety, and NSSI symptomatology. The developed DHI was described as a helpful and supportive tool.

Conclusion

The intervention has shown initial evidence to be feasible and beneficial for adolescents conducting NSSI. The DHI has demonstrated to be a valuable tool in the treatment of self-harming youth.

Predictors of non-suicidal self-injury in adolescents with depressive disorder: the role of alexithymia, childhood trauma, and body investment

Purpose

This study analyzes the relationship of alexithymia, childhood trauma, and body investment to non-suicidal self-injury (NSSI) behaviors in adolescents with depressive disorder and whether they have predictive and diagnostic value for non-suicidal self-injury (NSSI) behaviors in adolescents with depressive disorder.

Patients and methods

A total of 225 patients with a diagnosis of adolescent depressive disorder were included in the study and were divided into two groups according to the DSM-5 criteria: 98 cases without NSSI and 127 cases with NSSI. Compare the demographic data, 24-item Hamilton Depression Scale (HAMD-24), 20-item Toronto Alexithymia Scale (TAS-20), Childhood Trauma Questionnaire-Short Form (CTQ-SF), and Body Investment Scale (BIS) scores between two groups. Binary logistic regression was used to analyze the independent risk factors contributing to NSSI behaviors in adolescents with depression, and establish four predictive models. Based on the models' predictive probability, the ROC curves were plotted to calculate the value of the predictive diagnostic effect.

Results

The group without NSSI had lower scores than the group with NSSI on HAMD-24 total score, TAS-20 total score, difficulty identifying feelings, difficulty describing feelings, and externally focused thinking, as well as lower scores on CTQ-SF total score, physical neglect, emotional neglect, physical abuse, and emotional abuse. In contrast, the BIS total score, body image feelings and attitudes, body care, and body protection factor scores were higher for the group without NSSI. The BIS body care factor score and the CTQ-SF emotional abuse factor score were significantly linked with adolescents diagnosed with depressive disorder who exhibited NSSI behaviors. These results provide a good diagnostic model for adolescents with depressive disorder.

Conclusion

Low levels of body care and childhood emotional abuse may independently contribute to the implementation of NSSI in adolescents with depressive disorder. Body investment and childhood trauma are valuable in diagnosing and predicting NSSI behaviors and should be considered as potentially important factors in clinical treatment.

Diurnal variation of cardiac autonomic activity in adolescent non-suicidal self-injury

Heart rate (HR) and vagally mediated heart rate variability (HRV) are two distinct biomarkers of cardiac autonomic activity. Decreased cardiac vagal activity (or decreased HRV) in particular has been linked with impairments in the functional flexibility of the central autonomic network (CAN), resulting in impaired stress and emotion regulatory capacities. Decreased HRV is widely used as trait marker of psychopathology. Repetitive engagement in non-suicidal self-injury (NSSI) in adolescence correlates with both deficits in stress and emotion regulation, as well as decreased HRV. Existing research has, however, focused on short-term recordings of HR and HRV under resting and phasic conditions. In this study, we examined whether diurnal variation of cardiac autonomic activity, indexed by cosinor parameters of HR and HRV derived from 48 h of ambulatory ECG recording under natural conditions over a weekend, are altered in female adolescents with NSSI disorder compared to controls (HC; N = 30 per study group). Several important confounds, including physical activity, were controlled for. Female adolescents with NSSI show higher rhythm-adjusted 24 h mean levels and greater respective amplitude of HR, as well as lower rhythm-adjusted 24 h mean levels and smaller respective amplitude of HRV. Peak levels in both HR and HRV in the NSSI group were reached approximately 1 h later compared to HC. Severity of exposure to early life maltreatment might be linked with altered amplitudes of 24 h HR and HRV. Diurnal rhythms of cardiac autonomic activity might hold promise as objective indicators of disordered stress and emotion regulation in developmental psychopathology, and as such should be investigated in future studies with rigorous assessment and control of potential confounds.

The Prediction Model of Non-Suicidal Self-Injury in Psychiatric Patients Using Decision Tree Analysis

PURPOSE

The prevalence rate of non-suicidal self-injury (NSSI) in the clinical population is higher than that in the community sample, necessitating the need to investigate the predicting factors of NSSI in this group. The present study aimed to develop a prediction model of NSSI among psychiatric patients in Korea.

MATERIALS AND METHODS

Decision tree analysis was conducted on a sample of 224 psychiatric patients. Emotion regulation strategies (rumination, cognitive reappraisal, and expressive suppression), impulsivity, problematic alcohol use, working memory, depressive mood, and gender were included in the model as predictors of NSSI.

RESULTS

Results indicated that rumination, problematic alcohol use, and working memory predicted lifetime NSSI engagement among psychiatric patients. The best predictor of lifetime NSSI engagement was rumination. Specifically, when the level of rumination was high, the level of working memory was lower, and the risk of NSSI was higher. In the case of low levels of rumination, the higher the level of problematic alcohol use, the higher the risk of NSSI. The highest prevalence of lifetime NSSI engagement was found in a subgroup of patients with high levels of rumination and low levels of working memory.

CONCLUSION

The major contribution of this study is finding a combination of factors to predict the high-risk group of NSSI among psychiatric patients in Korea. This study provides evidence on the effect of rumination, working memory, and problematic alcohol use on NSSI. It is suggested that clinicians and researchers should pay more attention to emotion regulation and related vulnerabilities in preventing and treating NSSI.

Micro-sequences of anger and shame and non-suicidal self-injury in youth: an ecological momentary assessment study

OBJECTIVE

Non-suicidal self-injury (NSSI) is a significant mental health concern with the highest prevalence among adolescents. NSSI has been conceptualized as one of the maladaptive strategies to cope with challenging affect or a form of self-punishment. Although characterizing moment-to-moment associations between shame and NSSI in individuals' real-world environment and partitioning between- and within-person effects is critical for mobile and timely interventions, most studies examined habitual experiences of negative affective states and focused on adults.

METHOD

In this study, we focused on in vivo anger at self and others and shame and NSSI among 158 adolescents 3 weeks following their psychiatric hospitalizations using ecological momentary assessment (EMA) technology.

RESULTS

We found that greater between-person levels of anger at self and others were linked to a higher number of subsequent NSSI occurrences within a day. These findings remained primarily unchanged when we statistically adjusted for participants' age, sex assigned at birth, the number of current psychiatric diagnoses, EMA response rates, and youth lifetime history of SI. Within-person increases in NSSI were linked to increased anger at self over and beyond between-person average levels of NSSI.

CONCLUSIONS

These findings highlight the potential regulatory role of NSSI to decrease negative affective states and point to the clinical utility of assessing and early mobile interventions targeting challenging affect in youth.

Examining the Presence, Frequency, and Associated Characteristics of Nonsuicidal Self-Injury by Proxy: Initial Validation of the Nonsuicidal Self-Injury by Proxy Questionnaire (NSSIBPQ)

Nonsuicidal self-injury (NSSI) by proxy is the intentional destruction of one's own body tissue through the elicitation of another being's actions. Despite its clinical relevance, research on NSSI by proxy is limited and there are no available measures of this behavior. This research aimed to characterize NSSI by proxy among young adults and provide preliminary data on the validity of a new self-report measure, the NSSI by Proxy Questionnaire (NSSIBPQ). Two nationwide community samples of young adults (one general community sample and one with a history of traditional NSSI and suicidality) completed online studies. NSSI by proxy was reported by 18% of the general community sample and 45% of the self-injuring sample. Findings support the clinical relevance of NSSI by proxy and its potential to meet criteria for an NSSI disorder diagnosis. Results also provide preliminary support for the internal consistency and convergent, discriminant, and concurrent validity of the NSSIBPQ.

Pattern of non-suicidal self-injury in Chinese male prisoners: A latent class analysis

OBJECTIVES

Nonsuicidal self-injury (NSSI) occurs more frequently in the prisoner population than in the general population. Monitoring and management of this behavior is challenging because NSSI may present in diverse ways. People often use more than one method of NSSI, and there are many possible combinations of these behaviors. We used latent class analysis (LCA) to identify subgroups of male inmates based on methods and frequency of NSSI.

METHODS

A total of 1042 male prisoners in China (Mage  = 38.45, SD = 10.67) completed measures of hopelessness, sensation seeking, identity integration, and suicidal ideation, and NSSI was assessed in a structured interview.

RESULTS

Results of the LCA supported a three-class model: high-NSSI (1.8%), moderate-NSSI (8.0%), and no-or-negligible NSSI (90.2%). Multinomial logistic regression analyses showed that prisoners in the high-NSSI and moderate-NSSI classes were significantly more likely than those in the no-or-negligible NSSI class to show high hopelessness, high sensation seeking, and low identity. Furthermore, suicidal ideation was significantly higher in the high-NSSI and moderate-NSSI classes than in the no-or-negligible NSSI class.

CONCLUSIONS

Classifying groups of prisoners based on features of NSSI is potentially useful for understanding risk factors and for developing tailored prevention and treatment strategies.

The pooled prevalence and influential factors of non-suicidal self-injury in non-clinical samples during the COVID-19 outbreak: A meta-analysis

BACKGROUND

COVID-19 has had an enormous impact on the mental health of people around the world, particularly adolescents. Non-suicidal self-injury (NSSI) is one of the most prominent and dangerous behaviors associated with suicide. However, few meta-analyses of the NSSI prevalence have ever been conducted since the COVID-19 outbreak. Here, we conducted a meta-analysis to estimate the pooled prevalence and elucidate the influencing factors for NSSI.

METHODS

We searched PubMed, Web of Science, Embase, APA PsycINFO, CNKI and Wanfang Database for relevant literature published before April 2022. Pooled prevalence and 95 % confidence interval (CI) were used to assess NSSI prevalence. Subgroup and meta-regression analyses were performed to clarify the potential influencing factors.

RESULTS

A total of 15 studies with 24,055 participants were eventually included. The results showed that the pooled overall prevalence of NSSI among overall samples during the COVID-19 pandemic was 22.5 % (95 % CI: 17.2 % to 28.9 %). Subgroup and meta-regression analyses revealed that the crucial influencing factors for NSSI included gender, age, regional distribution, and suicidal ideation. Specifically, the NSSI prevalence among adolescents and adults during the pandemic was 32.40 % and 15.70 %, respectively. Most importantly, gender is a significant influencing factor for NSSI among adolescents.

CONCLUSIONS

The pooled prevalence of NSSI during the COVID-19 outbreak has surged to alarming heights, especially among adolescents. The prevalence of NSSI may be influenced by complex factors such as gender and age. Therefore, it is critical to pay attention to NSSI behaviors in the adolescent population, particularly male adolescents who appear to be susceptible.

Longitudinal development of non-suicidal self-injury disorder in adolescence: Prospective prediction of stability and change by identity development, depression, trauma, and resilience

BACKGROUND

With the introduction of non-suicidal self-injury disorder (NSSI-D) in DSM-5, the field obtained a standardised set of criteria to study those engaging in more severe and chronic NSSI. To date, no previous research has studied the development of NSSI-D longitudinally, leaving questions on its stability and potential prospective predictors unanswered.

METHODS

2162 community adolescents (M = 15.00 years, SD = 1.88, 53.9 % girls at T1) completed a set of self-report questionnaires for three consecutive years and were classified into three severity-based NSSI subgroups (no-NSSI, subthreshold-NSSI, NSSI-D). Multinomial logistic regression analyses were used to prospectively predict subgroup membership by age, gender, identity development, depressive symptoms, traumatic experiences, and resilience.

RESULTS

At baseline, the sample was distributed over the no-NSSI group (88 %), the subthreshold-NSSI (6 %) and NSSI-D (6 %) groups. These groups respectively showed high (93.5 %), low (25 %) and moderate (47.5 %) stability over one-year intervals. Longitudinally, higher levels of identity confusion and trauma significantly increased the likelihood of transitioning to subthreshold-NSSI. Moreover, boys had a higher likelihood of transitioning from NSSI-D to no-NSSI over the course of one year.

CONCLUSIONS

This three-year study provides the first indication of the longitudinal course of NSSI-D with the current set of DSM-5 criteria. Clinically, the results suggest the particular potential of identity confusion and trauma as prevention targets in community adolescents.

Nonsuicidal Self-Injury in Preadolescents

OBJECTIVES

There is a dearth of literature on the prevalence and predictors of nonsuicidal self-injury (NSSI) history and onset among preadolescent youth. This gap in the literature is significant given evidence suggesting that NSSI is a robust predictor of negative mental health outcomes, and that early onset NSSI may be associated with a more severe course of self-injurious thoughts and behaviors. This study aimed to evaluate sociodemographic characteristics, psychiatric disorders, and suicidal ideation (SI) in relation to NSSI onset and history in preadolescents.

METHODS

Data were drawn from the Adolescent Brain and Cognitive Development (ABCD) study, which recruited a diverse sample of 11 875 youth aged 9 to 10 years. The primary outcome measures were lifetime history and recent onset of NSSI. Measures included sociodemographics and the K-SADS diagnostic interview assessing psychopathology and SI.

RESULTS

Female sex and identifying as Black were associated with lower odds of lifetime NSSI. Identifying as a sexual minority, having unmarried parents, and a low family income were associated with higher odds of lifetime NSSI. Although depression was most predictive of NSSI history and onset, a range of internalizing and externalizing disorders, greater comorbidity, and SI also were predictive.

CONCLUSIONS

Given that NSSI was associated with a range of mental health disorders and comorbidity, it may be best conceptualized as a transdiagnostic phenomenon. Findings highlight key sociodemographic and diagnostic factors that may help to direct screening efforts in preadolescents, particularly sexual minority status and depression.

Examining the relationship between non-suicidal self-injury and mental health among female Arab minority students: the role of identity conflict and acculturation stress

Background and objective

Research suggests that individuals from minority backgrounds, including immigrants and ethnic minorities, may be at a higher risk for non-suicidal self-injury (NSSI). The aim of the present research is to examine the relationship between non-suicidal self-injury (NSSI) and identity conflict and acculturation stress, depression, and risk behaviors among female Arab minority students.

Methods

The sample analyzed consisted of 1,529 female Arab students (85.8% B.A. students, 14% M.A. students) aged 21-54 (M = 23, SD = 4.17). The participants completed self-reported questionnaires assessing NSSI engagement, identity conflict and acculturation stress, depression, and risky substance use behavior.

Results

As expected, we found a significant positive association between NSSI and identity crisis. In addition, an identity conflict and acculturation stress impact the effect of depression and risky substance use behaviors in engaging in self-injury. Namely, participants were more likely to engage in NSSI when they also experienced identity conflict and acculturation stress and exhibited depressive symptoms and tended to display risky substance use behavior.

Conclusion

These findings provide evidence that the relationship between depression, risky substance use behavior, and NSSI may be stronger among individuals who experience higher levels of identity conflict and acculturation stress. Implications for intervention and future research are briefly presented.

Physiological response to pain in female adolescents with nonsuicidal self-injury as a function of severity

BACKGROUND

Preliminary evidence indicates altered hypothalamic-pituitary-adrenal (HPA) axis and autonomic nervous system (ANS) response to experimental pain in individuals with nonsuicidal self-injury (NSSI). This study investigated effects of NSSI severity and severity of psychopathology on the HPA axis and ANS response to pain.

METHODS

N = 164 adolescents with NSSI and n = 45 healthy controls received heat pain stimulation. Salivary cortisol, α-amylase and blood pressure were repeatedly assessed before and after painful stimulation. Heart rate (HR) and heart rate variability (HRV) were assessed continuously. NSSI severity and comorbid psychopathology were derived from diagnostic assessments. Main and interaction effects of time of measurement and NSSI severity, adjusted for severity of adverse childhood experiences, borderline personality disorder and depression, on HPA axis and ANS response to pain were examined using regression analyses.

RESULTS

Increasing NSSI severity predicted an increasing cortisol response (χ2(3) = 12.09, p = .007) to pain. After adjusting for comorbid psychopathology, greater NSSI severity predicted decreased α-amylase levels following pain (χ2(3) = 10.47, p = .015), and decreased HR (χ2(2) = 8.53, p = .014) and increased HRV(χ2(2) = 13.43, p = .001) response to pain.

LIMITATIONS

Future research should implement several NSSI severity indicators, potentially revealing complex associations with the physiological response to pain. Assessing physiological responses to pain in NSSI in a naturalistic setting presents a promising avenue for future research in NSI.

CONCLUSIONS

Findings indicate an increased pain-related HPA axis response and an ANS response characterized by reduced sympathetic and increased parasympathetic activity associated with NSSI severity. Results support claims for dimensional approaches to NSSI and its related psychopathology alongside shared, underlying neurobiological correlates.

Prefrontal oxygenation varies as a function of response inhibition performance in healthy participants but not in youth with non-suicidal self-injury

Non-suicidal self-injury (NSSI), a highly prevalent symptom in adolescence, has been associated with impulsivity. Behavioral measures of response inhibition in combination with the recording of brain activity potentially improve the understanding of the etiology of the behavior. We therefore investigated prefrontal cortex (PFC) oxygenation during a response inhibition task using functional near-infrared spectroscopy (fNIRS) in n = 152 adolescents with NSSI and n = 47 healthy controls. We compared groups regarding behavioral performance and PFC oxygenation and tested whether the association between task performance and PFC oxygenation differed between groups. PFC oxygenation was slightly higher in adolescents with NSSI than in controls. Further, there was evidence for a group by performance interaction: In healthy controls, higher oxygenated hemoglobin was associated with better task performance, which was not the case in the NSSI group. We did not find evidence of associations between PFC oxygenation and clinical measures. Our study provides preliminary evidence of altered brain functional correlates of response inhibition in adolescents with NSSI potentially reflecting deficient top-down regulation of limbic regions through prefrontal regions. Due to methodological limitations of the current study, findings must be interpreted with caution and future studies should optimize task designs for fNIRS processing.

The prevalence of self-injury in adolescence: a systematic review and meta-analysis

In the past 10 years, there has been a growing interest in self-injurious behavior (SIB) among adolescents. The lifetime prevalence of SIB is between 16 and 22% in community sample with females more likely to engage in SIB. There are conflicting results about the global distribution of the prevalence of SIB and whether the SIB has increased in the 21st century. Our aim in the current study was to conduct a systematic search of and meta-analysis on the prevalence of SIB in adolescents over the past 5 years' worth of published papers and to examine gender, continental, and year differences. We conducted a systematic search in June 2020 of six databases (PubMed, Scopus, Web of Science, OVID Medline, PsycINFO, EBSCO) with three main search terms: "self-injurious behavior," "prevalence," and "adolescence." Article inclusion criteria were (a) written in English; (b) published between January 1, 2015, and June 18, 2020; and (c) focused on a community sample. Titles and abstracts of the articles were screened first. Then, the relevant full texts were read, and those that met the inclusion criteria were collected. We used Comprehensive Meta-Analysis software was used to conduct the analyses. After the screening process 97, articles were included in the meta-analysis. The age of the samples ranged from 11.00 to 18.53 years. The overall average prevalence of nonsuicidal self-injury in the studies was 16%. There was a significant gender difference: females reported a higher prevalence than males (19.4% and 12.9%, respectively). A significantly higher prevalence was found among Asian articles than those from other continents (19.5% and 14.7%, respectively). The prevalence of SIB did not change significantly between 2013 and 2018. The current research draws attention to the high prevalence of SIB among adolescents, especially among females and those living in Asia. It is important to address this behavior, both in terms of prevention and intervention.

Mental imagery of suicide and non-suicidal self-injury: A meta-analysis and systematic review

BACKGROUND

The vast majority of research on, and clinical assessment of, cognitions related to suicide and non-suicidal self-injury (NSSI) has focused on verbal thoughts. And yet, mental imagery is more realistic and emotionally arousing than verbal thoughts.

METHODS

We conducted a systematic review and meta-analysis documenting the prevalence of suicidal and NSSI mental imagery and describing the content and characteristics of suicidal and NSSI mental imagery, links between suicidal and NSSI mental imagery and suicidal and NSSI behavior, and how to intervene on suicidal and NSSI mental imagery. Studies published through December 17, 2022 were identified through a systematic search of MEDLINE and PsycINFO.

RESULTS

Twenty-three articles were included. Prevalence rates of suicidal (73.56%) and NSSI (84.33%) mental imagery were high among clinical samples. Self-harm mental imagery commonly depicts engagement in self-harm behavior and is experienced as vivid, realistic, and preoccupying. When experimentally induced, self-harm mental imagery reduces physiological and affective arousal. Preliminary evidence suggests that suicidal mental imagery is associated with suicidal behavior.

CONCLUSIONS

Suicidal and NSSI mental imagery are highly prevalent and may be associated with heightened risk for self-harm behavior. Assessments and interventions for self-harm should consider incorporating and addressing suicidal and NSSI mental imagery to mitigate risk.

Relationship between alexithymia, loneliness, resilience and non-suicidal self-injury in adolescents with depression: a multi-center study

OBJECTIVE

Non-suicidal self-injury (NSSI) behaviors are prevalent in adolescents and have adverse effects on physical and mental health. However, little is known about the relationship between NSSI and alexithymia, or the underlying mechanisms that could explain this relationship. This study aimed to elucidate the current status of NSSI in adolescent depression, and analyze the relationship between alexithymia, loneliness, resilience, and adolescent depression with NSSI, so as to provide a theoretical basis for psychotherapeutic interventions.

METHOD

The study sample involved inpatients and outpatients from 12 hospitals across China and adolescents with depression who met the DSM-5 diagnostic criteria for depression episode. The following scales were used: The Functional Assessment of Self-Mutilation, Toronto Alexithymia Scale, UCLA Loneliness Scale, and Connor Davidson Resilience Scale.

RESULTS

The detection rate of NSSI in adolescents with depression from 2021.01.01-2022.01.01 was 76.06% (1782/2343). Spearman's correlation analysis revealed a significant correlation between alexithymia, loneliness, resilience and NSSI in depressed adolescents, and the results of the non-parametric test showed that the differences between the two groups for each factor were statistically significant. Binary logistic regression results showed that alexithymia (B = 0.023, p = 0.003, OR = 1.023, 95% CI: 1.008-1.038) and depression (B = 0.045, p < 0.001, OR = 1.046, 95% CI: 1.026-1.066) are risk factors for NSSI, resilience (B = - 0.052, p < 0.001, OR = 0.949, 95% CI: 0.935 - 0.964) is a protective factor for NSSI. Alexithymia directly predicted NSSI and also indirectly influenced NSSI through the mediated effect of resilience. Loneliness moderates the first half of the path of this mediated model.

CONCLUSION

The present study confirms a moderated mediation effect: Alexithymia can have an impact on NSSI behaviors in depressed adolescents through the mediating role of resilience. Loneliness, as a moderating variable, moderated the first half of the pathway of the mediating model. We discuss perspectives for future research and interventions based on the findings of the study.

Abnormal brain spontaneous activity in major depressive disorder adolescents with non-suicidal self injury and its changes after sertraline therapy

Background

Non-suicidal self-injury (NSSI) commonly occurs among adolescents with major depressive disorder (MDD), causing adverse effects on the physical and mental health of the patients. However, the underlying neurobiological mechanism of NSSI in adolescents with MDD (nsMDDs) remains unclear, and there are still challenges in the treatment. Studies have suggested that sertraline administration could be an effective way for treatment.

Methods

To verify the effectiveness and to explore the neurobiological processes, we treated a group of adolescents with nsMDDs with sertraline in this study. The brain spontaneous activity alteration was then investigated in fifteen unmedicated first-episode adolescent nsMDDs versus twenty-two healthy controls through the resting-state functional magnetic resonance imaging. Besides the baseline scanning for all participants, the nsMDDs group was scanned again after eight weeks of sertraline therapy to examine the changes after treatment.

Results

At pre-treatment, whole brain analysis of mean amplitude of low-frequency fluctuation (mALFF) was performed to examine the neuronal spontaneous activity alteration, and increased mALFF was found in the superior occipital extending to lingual gyrus in adolescent nsMDDs compared with controls. Meanwhile, decreased mALFF was found in the medial superior frontal in adolescent nsMDDs compared with controls. Compared with the pre-treatment, the nsMDDs group was found to have a trend of, respectively, decreased and increased functional neuronal activity at the two brain areas after treatment through the region of interest analysis. Further, whole brain comparison of mALFF at pre-treatment and post-treatment showed significantly decreased spontaneous activity in the orbital middle frontal and lingual gyrus in adolescent nsMDDs after treatment. Also, depression severity was significantly decreased after treatment.

Conclusion

The abnormal functional neuronal activity found at frontal and occipital cortex implied cognitive and affective disturbances in adolescent nsMDDs. The trend of upregulation of frontal neuronal activity and downregulation of occipital neuronal activity after sertraline treatment indicated that the therapy could be effective in regulating the abnormality. Notably, the significantly decreased neuronal activity in the decision related orbital middle frontal and anxiety-depression related lingual gyrus could be suggestive of reduced NSSI in adolescent MDD after therapy.

Non-suicidal self-injury and professional psychological help-seeking among Chinese left-behind children: prevalence and influencing factors

BACKGROUND

Non-suicidal self-injury (NSSI) is a risk factor for suicide. This study aimed to investigate the prevalence of NSSI and professional psychological help-seeking status and influencing factors among left-behind children (LBC) in China.

METHODS

We implemented a population-based cross-sectional study in participants aged 10-18 years. Sociodemographic characteristics, NSSI, help-seeking status and coping style were measured by self-reported questionnaires. A total of 16,866 valid questionnaires were collected, including 6096 LBC. Binary logistic regression models were used to analyze the factors influencing NSSI and professional psychological help-seeking.

RESULTS

The incidence of NSSI among LBC was 4.6%, significantly higher than that of non-left-behind children (NLBC). This incidence was higher among girls. Moreover, 53.9% of LBC with NSSI did not receive any treatment and only 22.0% sought professional psychological help. LBC often adopt emotion-oriented coping styles, specifically, those with NSSI. LBC with NSSI who seek professional help tend to adopt problem-oriented coping styles. Logistic regression analysis revealed that girls, learning stage, single-parent, remarried families, patience, and emotional venting were risk factors for NSSI in LBC, while problem-solving and social support seeking were protective factors. Moreover, problem-solving was also a predictor for seeking professional psychological help, patience will prevent it.

LIMITATIONS

This was an online survey.

CONCLUSIONS

The prevalence of NSSI in LBC is high. Gender, grade, family structure, and coping style affect the occurrence of NSSI among LBC. Only a few LBC with NSSI seek professional psychological help, while the coping style will affect the help-seeking behavior.

Multifaceted risk for non-suicidal self-injury only versus suicide attempt in a population-based cohort of adults

BACKGROUND

Non-suicidal self-injury and suicide attempt represent significant public health concerns. While these outcomes are related, there is prior evidence that their etiology does not entirely overlap. Efforts to directly differentiate risk across outcomes are uncommon, particularly among older, population-based cohorts.

METHODS

This research has been conducted using the UK Biobank. Data on individuals' self-reported history of non-suicidal self-injury only versus suicide attempt (maximum N = 6643) were analyzed. Applying LASSO and standard logistic regression, participants reporting one of these outcomes were assessed for differences across a range of sociodemographic, behavioral, and environmental features.

RESULTS

Sociodemographic features most strongly differentiated between the outcomes of non-suicidal self-injury only versus suicide attempt. Specifically, Black individuals were more likely to report a suicide attempt, as were those of mixed race, those endorsing higher levels of depressive symptoms or trauma history, and those who had experienced financial problems (odds ratios 1.02-3.92). Those more likely to engage in non-suicidal self-injury only were younger, female, had higher levels of education, those who resided with a partner, and those who had a recently injured relative.

LIMITATIONS

Differences in timing across correlates and outcomes preclude the ability to establish causal pathways.

CONCLUSIONS

The factors identified in the current study as differentially associated with non-suicidal self-injury only versus suicide attempt provide further evidence of at least partially distinct correlates, and warrant follow-up in independent samples to investigate causality.

Resting-state functional connectivity predicting clinical improvement following treatment in female adolescents with non-suicidal self-injury

BACKGROUND

Non-suicidal self-injury (NSSI) is highly prevalent among adolescents and predicts future psychopathology including suicide. To improve therapeutic decisions and clinical outcome of patients engaging in NSSI, it seems beneficial to determine neurobiological markers associated with treatment response. The present study investigated whether resting-state functional brain connectivity (RSFC) served to predict clinical improvements following treatment in adolescents engaging in NSSI.

METHODS

N = 27 female adolescents with NSSI took part in a baseline MRI exam and clinical outcome was assessed at follow-ups one, two and three years after baseline. During the follow-up period, patients received in- and/or outpatient treatment. Mixed-effects linear regression models were calculated to examine whether RSFC was associated with clinical improvement.

RESULTS

Patients' clinical outcome improved across time. Lower baseline RSFC between left paracentral gyrus and right anterior cingulate gyrus was associated with clinical improvement from baseline to one-year and from two-year to three-year follow-up. Lower and higher baseline RSFC in several inter- and intrahemispheric cortico-cortical and cortico-subcortical connections of interest were associated with clinical symptomatology and its severity, independent from time.

LIMITATIONS

A relatively small sample size constrains the generalizability of our findings. Further, no control group not receiving treatment was recruited, therefore clinical changes across time cannot solely be attributed to treatment.

CONCLUSIONS

While there was some evidence that RSFC was associated with clinical improvement following treatment, our findings suggest that functional connectivity is more predictive of severity of psychopathology and global functioning independent of time and treatment. We thereby add to the limited research on neurobiological markers as predictors of clinical outcome after treatment.

Experiential Avoidance, Posttraumatic Stress Disorder, and Self-Injurious Thoughts and Behaviors: A Moderation Analysis in a National Veteran Sample

Experiential avoidance (EA) is associated with posttraumatic stress disorder (PTSD) and self-injurious thoughts and behaviors (SITBs) across different populations, and extant literature has demonstrated a strong relationship between PTSD and SITBs. However, no study has explored the potential moderating role EA plays in the association of PTSD with nonsuicidal self-injury (NSSI), suicidal ideation, and suicide attempts. The objective of the present study was to determine if EA would moderate the association with PTSD and SITBs such that the association between PTSD and individuals SITBs would be stronger among individuals with higher EA. In a large national sample of Gulf War Era veterans (N = 1,138), EA was associated with PTSD, lifetime and past-year NSSI, current suicidal ideation, and lifetime suicide attempts in bivariate analyses. Multivariate analyses detected a significant EA by PTSD interaction on lifetime NSSI (AOR = 0.96), past-year NSSI (AOR = 1.03), and suicide attempts (AOR =1.03). Probing of the interactions revealed that the respective associations between PTSD, lifetime and past-year NSSI, and suicide attempts were stronger at lower levels of EA (i.e., better), counter to our hypotheses. These preliminary findings contextualize the relationship between these variables in a Gulf War veterans sample and signal the need to further investigate these relationships. Further, these findings highlight the need for advancement in assessment and intervention of EA and SITBs.

Linking non-suicidal self-injury to psychopathology: The utility of transdiagnostic and DSM-based models

Non-suicidal self-injury (NSSI) is a significant public health concern, and its primary formal link to the universe of psychopathology content in DSM diagnoses has been mostly through borderline personality disorder (BPD). Recent research has produced ample evidence of weaknesses of diagnoses relative to transdiagnostic psychopathology dimensions, and found that NSSI-related variables like suicidality are best predicted by transdiagnostic versus diagnosis-based variables. These findings suggest a need to characterize how NSSI may relate to different forms of psychopathology classification constructs. We examined how transdiagnostic dimensions of psychopathology relate to NSSI, focusing on how transdiagnostic (shared) variance of dimensional psychopathology spectra might differentially explained the variance in NSSI relative to traditional DSM diagnoses. In two nationally representative United States samples (Ns = 34,653 and 36,309), we modeled the common distress-fear-externalizing transdiagnostic comorbidity model and investigated questions of predictive utility of these dimensional and categorical psychopathology structures. Transdiagnostic dimensions were superior in predicting NSSI compared to common DSM-IV and DSM-5 diagnoses. These dimensions accounted for 33.6-38.7 % of NSSI variance across all analyses in both samples. DSM-IV/DSM-5 diagnoses, however, demonstrated only modest incremental prediction of NSSI over and above the transdiagnostic dimensions. These results support a transdiagnostic reconceptualization of NSSI's links with psychopathology and highlight the importance of transdiagnostic dimensions for predicting clinical outcomes relating to self-injurious behaviors. Implications for research and clinical practice are discussed.

Exploring the association of addiction-related genetic factors with non-suicidal self-injury in adolescents

Background

Non-suicidal self-injury (NSSI) is self-injurious behavior without suicidal intent commonly seen in the adolescent population and poses a serious threat to the life safety of adolescents. Related researches suggest a possible correlation between addiction and the occurrence of NSSI. This study aimed to explore the correlation between addiction and NSSI from a molecular biological perspective by analyzing the differential expression of addiction-related genes in NSSI patients.

Methods

(1) The association between addiction and non-suicidal self-injury in a Chinese adolescent population was verified with the help of questionnaires on substance and non-substance addictions and non-suicidal self-injury among 1,329 adolescents in China, (2) Screening for key genes associated with addiction by bioinformatics analysis, and (3) RT-qPCR experiment was performed to validate key genes and Receiver Operating Characteristic curves were plotted for target genes.

Results

(1) Substance and non-substance addictions were all significantly correlated with non-suicidal self-injury, (2) Four target genes: SERPINA3, SLC14A1, RPS6 and RPS3A were screened by bioinformatics technique, and (3) Relative quantitative analysis by RT-qPCR revealed that the expression levels of SLC14A1 (p < 0.01), RPS6 (p < 0.05) and RPS3A (p < 0.01) were significantly higher in NSSI patients than in healthy controls.

Conclusion

(1) The significant association between addiction and NSSI exists in the Chinese adolescent population and (2) Addiction-related genes SLC14A1, RPS6, and RPS3A are differentially expressed in adolescents with NSSI. The genes have the potential to become biological markers for the diagnosis of NSSI.

An Integrative Model of In-Hospital and Out-of-Hospital Nursing Care for Non-Suicidal Self-Injury: A Narrative Review

Background: Non-suicidal self-injury (NSSI) refers to the intentional and repeated physical trauma of an individual without explicit suicidal intent, which has negative effects on the physical and mental well-being of an individual, especially for adolescents. Timely and accessible nursing care may play an important role in the survival and rehabilitation process of NSSI. Methods: In this review, we systematically discuss the nursing care of NSSI behavior and provide recommendations based on an integrated nursing model for NSSI management. Results: As reported in previous studies, a variety of factors can contribute to NSSI behavior, such as personality traits, current psychological status, history of mental illnesses, as well as family and social factors. In-hospital care is the most necessary and effective care during acute episodes of NSSI behavior. To effectively manage inpatients with NSSI behaviors, nurses should first understand the motivation of NSSI, and provide comprehensive and multi-level care through nurse-patient communication, individualized psychological care, and multidisciplinary cooperation with other professionals. While the purpose of out-of-hospital nursing is to reduce the frequency of NSSI behaviors by screening high-risk individuals, providing psychological support, promoting health education, and improving self-awareness. Conclusions: An integrative model of in-hospital and out-of-hospital nursing care can help improve the clinical management and long-term prognosis of patients with NSSI and minimize the risk of suicidal ideation or suicidal behavior.

Violência Autoprovocada no Brasil: Caracterização dos Casos Notificados entre 2009 e 2021

A violência autoprovocada consiste em um problema de saúde pública, devido a sua elevada incidência e prejuízos decorrentes. A notificação dessa conduta ocorre por meio do Sistema de Vigilância de Violências e Acidentes (VIVA), que integra o Sistema de Informação de Agravos de Notificação (SINAN). O objetivo deste estudo foi caracterizar os casos notificados no Brasil a partir dos registros do SINAN correspondentes ao período de 2009 a 2021. Análises descritivas revelaram o crescimento dos registros no Brasil, envolvendo, predominantemente, pessoas do sexo feminino, com idades entre 15 e 29 anos, de cor branca e ensino fundamental incompleto ou médio completo. As agressões ocorreram majoritariamente na própria residência e abarcaram mais de um episódio. Reforça-se a relevância de avaliar as características da violência autoprovocada, de modo a vislumbrar fatores de risco e de proteção associados ao fenômeno para o delineamento de ações e políticas públicas.

An investigation of self-injury in female adolescents: a qualitative study

This study aimed to investigate the phenomenon of self-injury among female adolescents. The research was qualitative, and the sampling method was purposive non-random; the sample size was 20 Iranian girl adolescents aged 13-15 years who had experienced non-suicidal self-injury. Data were collected through semi-structured interviews. The data analysis process was performed during three coding steps (open, axial, selective), through which the basic codes and categories were identified. Study results indicate that the main factors in adolescents' self-injury were individual or psychological (thoughts, emotions, and behaviors) and social (peers, family, communication with different gender, communication with others, media/cyberspace, school, and economic). In the former, the role of emotions was remarkable, while in the latter, the family played a key role. Further, results revealed that communication within the family was an important motivating and sustentative factor in adolescents' self-injury. The results can help counselors in working with adolescents who self-injure; results can also be used in the development and implementation of treatment plans.

Development and validation of a prediction nomogram for non-suicidal self-injury in female patients with mood disorder

Background

Non-suicidal self-injury (NSSI) is a highly prevalent behavioral problem among people with mental disorders that can result in numerous adverse outcomes. The present study aimed to systematically analyze the risk factors associated with NSSI to investigate a predictive model for female patients with mood disorders.

Methods

A cross-sectional survey among 396 female patients was analyzed. All participants met the mood disorder diagnostic groups (F30-F39) based on the Diseases and Related Health Problems 10th Revision (ICD-10). The Chi-Squared Test, t-test, and the Wilcoxon Rank-Sum Test were used to assess the differences of demographic information and clinical characteristics between the two groups. Logistic LASSO Regression Analyses was then used to identify the risk factors of NSSI. A nomogram was further used to construct a prediction model.

Results

After LASSO regression selection, 6 variables remained significant predictors of NSSI. Psychotic symptom at first-episode (β = 0.59) and social dysfunction (β = 1.06) increased the risk of NSSI. Meanwhile, stable marital status (β = -0.48), later age of onset (β = -0.01), no depression at onset (β = -1.13), and timely hospitalizations (β = -0.10) can decrease the risk of NSSI. The C-index of the nomogram was 0.73 in the internal bootstrap validation sets, indicated that the nomogram had a good consistency.

Conclusion

Our findings suggest that the demographic information and clinical characteristics of NSSI can be used in a nomogram to predict the risk of NSSI in Chinese female patients with mood disorders.

The epidemiology of non-suicidal self-injury: lifetime prevalence, sociodemographic and clinical correlates, and treatment use in a nationally representative sample of adults in England

BACKGROUND

Although the clinical importance of non-suicidal self-injury (NSSI) has received increasing recognition, relatively little is known about its epidemiology. The objective of this study was to estimate the lifetime prevalence of NSSI in adults and its association with sociodemographic characteristics, psychiatric disorders, and lifetime treatment for NSSI.

METHODS

A nationally representative face-to-face survey was conducted with 7192 adults aged ≥18 years in England. Respondents were interviewed about engagement in NSSI, psychiatric illness, suicidal thoughts and behavior, and treatment history for this behavior.

RESULTS

The estimated lifetime prevalence rate of NSSI was 4.86%. Younger age, growing up without biological parents in the household, being unmarried, and impoverished backgrounds were associated with NSSI. The majority of respondents with lifetime NSSI (63.82%) had at least one current psychiatric disorder. Most psychiatric conditions were associated with greater odds of lifetime NSSI in multivariate models. NSSI was strongly associated with suicidal ideation and suicide attempts, respectively, even after accounting for psychiatric disorders and sociodemographic covariates. A substantial proportion of respondents with NSSI history (30.92%) have engaged in medically severe self-harm, as indexed by requiring medical attention for this behavior. The majority of respondents with NSSI (56.20%) had not received psychiatric care for this behavior.

CONCLUSIONS

NSSI is prevalent in the general population and associated with considerable psychiatric comorbidity. A high rate of unmet treatment needs is evident among those with this behavior. Those at the greatest lifetime risk for NSSI may also be particularly limited in their resources to cope with this behavior.

Trajectories of nonsuicidal self‐injury during adolescence

OBJECTIVE

Although nonsuicidal self-injury is a public health concern, there is little information on how it changes across adolescence or what contributes to stability or change. We aimed to identify trajectories of stability and change in self-injury from ages 13 to 17 years, and to identify interpersonal and intrapersonal correlates that differentiate between trajectories of stability and change.

METHOD

We used five annual waves of cohort-sequential data, targeting 7th and 8th graders attending all public schools in three municipalities in central Sweden. The data were gathered via questionnaires, using a multi-item measure of non-suicidal self-injury and assessing negative experiences at home, in school, with peers, and in romantic settings, as well as intrapersonal issues (internalizing symptoms and difficulties with emotional, and behavioral regulation). The analytic sample was 3195 adolescents (51.7% boys, 48.3% girls; ages 12-16 years at T1, M = 13.61; SD = 0.66), most of whom were born in Sweden (88.6%) to at least one parent of Swedish origin (77.4%).

RESULTS

Latent growth curve modeling revealed three self-injury trajectories: a stable-low, a low-increasing, and an increasing-decreasing trajectory. Adolescents in the stable-low class reported the best overall adjustment at ages 13 and 16. Comparatively, adolescents in the other two classes reported similar levels of difficulty interpersonally and intrapersonally. Where they differed, the increase-decrease class fared worse than the low-increasing class.

CONCLUSIONS

This study suggests the need to frame self-injury as having multiple directions of development during adolescence and develop theory that aligns with differential patterns of self-injury development.

Is the end in the beginning? Child maltreatment increases the risk of non-suicidal self-injury and suicide attempts through impaired personality functioning

BACKGROUND

Child maltreatment is a risk factor for a range of mental disorders later in life, including dangerous self-harm and suicide attempts. A better understanding of the mechanisms underlying this association can inform prevention and intervention.

OBJECTIVE

To investigate personality functioning as a potential mediator of the association of childhood abuse and neglect and self-harm and suicide attempts in the general population.

PARTICIPANTS AND SETTING

Data were drawn from a representative German population sample (N = 2510).

METHODS

Participants filled out the Childhood Trauma Questionnaire (CTQ), OPD Structure Questionnaire (OPD-SQS), and items of the Self-Injurious Thoughts and Behaviors Interview (SITBI). In structural equation models, we operationalized impaired personality functioning as the mediator between childhood abuse and neglect and self-harm.

RESULTS

Individuals with a history of self-harm (combining suicide attempts, N = 47, and non-suicidal self-injury, N = 83) reported more childhood abuse and neglect (d = 1.39, p < .001) and greater impairments in personality functioning (d = 1.64, p < .001) than the rest of the population. The indirect effect via personality functioning accounted for 48.8 % of the total effect of childhood abuse and neglect on self-harm. In more differentiated analyses, emotional abuse showed the strongest association with self-harm. Only physical and sexual abuse had direct effects.

CONCLUSIONS

The results specify the relationship between child maltreatment and self-harm by demonstrating that it is partly mediated by basic functions of personality assessed using a dimensional measure. These abilities constitute modifiable risk factors that can be addressed by psychotherapy.

Pilot Study: Cut the Cut-A Treatment Program for Adolescent Inpatients with Nonsuicidal Self-Injury

Non-suicidal-self-injury (NSSI) in adolescents needing inpatient treatment is a serious health risk behaviour. NSSI-specific treatment programs for inpatients hardly exist. "Cut the Cut" (CTC) is a new treatment program in intervals, addressing this problem. Aim of this pilot-study was to evaluate acceptability and feasibility of CTC. 23 female inpatients (12 CTC, 11 control, aged 15-17; mean = 16.80, SD.70) engaging in NSSI were evaluated for service user satisfaction, frequency, and severity of NSSI at T1 (admission), T2 (discharge after interval 1, CTC-group) and T3 (discharge). A qualitative interview was performed at T3. Significant improvement in NSSI-frequency was given (T1-T3: CTC p = 0.010; control p = 0.038). Severity of NSSI reduced slightly (mild NSSI: CTC p = 0.022, control p = 0.087; severe NSSI: CTC p = 0.111, control p = 0.066). Satisfaction of parents (T3 mean 28.38) and adolescents (T3 mean 26.11) in CTC was rated high. CTC is a feasible treatment option for inpatients engaging in NSSI. Further studies over time are needed.Trial registration Number DRKS00016762, 05.03.2019, retrospectively registered.

Hiding in the open: Consideration of nonsuicidal self-injury by proxy as a clinically meaningful construct

Nonsuicidal self-injury (NSSI) is defined as the deliberate destruction of one's own body tissue without suicidal intent and for purposes not socially sanctioned. However, this definition limits the understanding and assessment of NSSI by excluding a clinically relevant form of NSSI that is both self-driven and associated with self-injurious intentions: NSSI by proxy. Specifically, we propose that NSSI by proxy be defined as the intentional destruction of one's own body tissue through the elicitation of another being's (e.g., human, animal) actions, wherein the agency of the person being injured is a critical facet of the behavior. We review the literature supporting the clinical relevance of this behavior, as well as its similarities to traditional NSSI. Next, we propose four behaviors that may be conceptualized as NSSI by proxy, and identify two other behaviors that warrant further investigation. Finally, we identify future directions for research in this area and implications for the assessment and treatment of NSSI.

Neurocognitive functioning in adolescents with non-suicidal self-injury

BACKGROUND

Non-suicidal self-injury (NSSI) is a highly prevalent transdiagnostic psychiatric symptom in adolescents. Research in adults has begun to investigate neurocognitive processes associated with NSSI as potential underlying phenotypes. However, research on neurocognitive function in adolescent patients with NSSI is scarce.

METHODS

In this study, we examined neurocognitive functioning in the domains of processing speed, attention, learning, working memory, and executive function in a relatively large sample of n = 240 adolescent patients engaging in NSSI and n = 49 healthy controls. Further, associations between neurocognitive performance and clinical characteristics in the patient group were examined.

RESULTS

While conventional regression analyses showed somewhat weaker neurocognition in the NSSI group in several domains, propensity score matching for IQ showed little evidence that patients engaging in NSSI showed worse neurocognition when general intelligence was considered. Further, a random forest machine learning algorithm was not able to classify NSSI vs. control groups based on neurocognitive features. Within the patient group, linear regression and latent class analyses yielded little evidence that neurocognitive performance was related with clinical characteristics or phenotypes.

LIMITATIONS

As the study did not include a clinical control group, findings might not be specific to NSSI.

CONCLUSIONS

Our findings challenge the importance of specific neurocognitive measures related to the presence or severity of NSSI in adolescents. Future studies should consider general intelligence as an important confounding factor and should focus on domains of affective cognition. Finally, longitudinal studies are needed to determine whether low neurocognitive performance serves to inform prognosis of NSSI or psychopathology in general.

Association of socioeconomic status with nonsuicidal self-injury and suicidal ideation in young Korean adults

OBJECTIVE

Although nonsuicidal self-injury (NSSI) in youth is an important mental health concern worldwide, limited studies have investigated its sociodemographic correlates in early adulthood. This study explored associations between socioeconomic status (SES) and self-harm behaviors, including NSSI and suicidal ideation, in a community-based sample of young adults.

METHODS

A total of 414 Korean young adults engaged in NSSI and 200 controls completed online self-report questionnaires assessing sociodemographic and clinical characteristics, using logistic regression to estimate the odds ratio and analyzed risk factors for NSSI, especially the independent influence of SES on NSSI risk. Multivariate regression was performed to identify the role of socioeconomic disadvantage in suicidal ideation in NSSI people.

RESULTS

Logistic regression showed that low SES significantly increased NSSI risk. Multivariable regression also revealed that lower SES was related to more severe suicidal ideation in young adults with NSSI after controlling for gender and the higher-severity NSSI index, including the number of NSSI methods used and NSSI intrapersonal functions.

CONCLUSIONS

This is the first study to directly address socioeconomic gradients of a general population of young adults with NSSI and its effects, and socioeconomic status should be considered preemptively when defining suicide risks of this group and when intervening in self-injurious behaviors.

Mediating role of depression in the association between alexithymia and nonsuicidal self-injury in a representative sample of adolescents in Taiwan

BACKGROUND

Nock's (2009) integrated theoretical model suggests that specific intrapersonal vulnerability factors caused by distal risk factors contribute to the development of nonsuicidal self-injury (NSSI). Alexithymia and depression have been found to predict NSSI. Based on Nock's model, alexithymia plays a distal risk factor role to increase the risk of depression-an intrapersonal vulnerability factor-and further increase the risk of NSSI. However, small or unrepresentative samples in past studies limit the generalizability of the results. This study examined the roles of depression and alexithymia in predicting NSSI, as well as the mediating effect of depression in the relation between alexithymia and NSSI in a large representative sample of adolescents in Taiwan.

METHODS

Using a cross-sectional study design, a large representative sample of 2,170 senior high school students in Taiwan was assessed by self-report measures of alexithymia, depression, and NSSI. Mediation analyses were performed to examine whether the relation between alexithymia and NSSI was mediated by depression. The questionnaires were administered in classrooms.

RESULTS

Results showed that alexithymia positively predicted NSSI (β = 0.23, p < .001) and depression can also positively predict NSSI (β = 0.41, p < .001). Additionally, the association between alexithymia and NSSI was fully mediated by depression.

CONCLUSIONS

This study data provided evidence for the mediating role of depression between alexithymia and NSSI, which can be explained by Nock's (2009) integrated theoretical model. The implications of the findings for future research and intervention were discussed.

The Psychosocial Correlates of Non-suicidal Self-Injury Within a Sample of Adolescents With Mood Disorder

Background

According to the integrated theoretical model, adolescents' behaviors were the outcome of the complex interplay between multiple levels. Non-suicidal self-injury (NSSI) is a serious and high prevalent problem among adolescents with mood disorders. However, a systematic perspective on psychosocial correlates among Chinese clinical adolescents is still rare.

Method

The impact of several factors at the individual (i.e., sex, age, self-esteem, and psychological distress), family (i.e., family structure, family income, and family support), and social level (i.e., living environment, peer support, and teacher support) on the frequency of NSSI behaviors were investigated in the current study. This research included 621 Chinese adolescents with mood disorders from 20 hospitals.

Results

Three-steps hierarchical regression analyses indicated that lower levels of psychological distress and higher levels of self-esteem were most associated with less frequency of NSSI behaviors. In addition, family support was negatively associated with the frequency of NSSI behaviors. After controlling the factors at individual and family levels, no significant association was found between the factors at the social level and the frequency of NSSI behaviors.

Conclusion

These findings provide preliminary support for the notion that adolescent self-esteem and family support may effectively shield them from problematic behavior; nevertheless, adolescents suffering from more emotional pain can be even riskier. Thus, further intervention strategies should consider the non-independence of individual capacities, co-combinatory effects of mood disorder, and family environment in treating those vulnerable Chinese adolescents.

Understanding Nonsuicidal Self-Injury

ABSTRACT

Nonsuicidal self-injury has existed since biblical times. It is increasing and gaining acceptance particularly among adolescents. Spiritual discontent or doubt is often a component. Therapeutic interventions include cognitive and behavior practices and developing strong, sustained relationships with patients to encourage healthy transformation.

Different Ways to Drown Out the Pain: A Meta-Analysis of the Association Between Nonsuicidal Self-Injury and Alcohol Use

OBJECTIVE

There is a significant overlap in the motivations for nonsuicidal self-injury (NSSI) and alcohol use. Moreover, several theories would predict that more frequent alcohol use is likely associated with more NSSI engagement. Still, the size and direction of this association has not been well documented in the literature.

METHOD

To address this gap, the goal of this article was to conduct a meta-analysis of the relation between alcohol use and NSSI.

RESULTS

Across 57 samples and 141,669 participants, we found that there was a significant positive association between NSSI and alcohol use, odds ratio = 1.78, 95% confidence interval [1.53, 2.07], k = 64, m = 52. Moderator analyses found that this effect was stronger for younger samples and samples with more severe alcohol use problems.

CONCLUSIONS

These results help establish a link between NSSI and alcohol use. Implications and future directions for NSSI research and intervention are discussed.HighlightsThere are several reasons to think that NSSI and alcohol use are linked.No reviews or meta-analyses have been conducted.We found a significant and small effect linking greater NSSI with greater alcohol use.

Lifetime prevalence and clinical correlates of nonsuicidal self-injury in youth inpatients with eating disorders: a retrospective chart review

BACKGROUND

Youths with eating disorders (EDs) engaging in nonsuicidal self-injury (NSSI) are at higher suicide risk because EDs and NSSI are associated with suicidality. However, epidemiologic data on NSSI lacks in the vulnerable group of youth ED inpatients.

METHODS

This retrospective chart review included patients up to 18 years of age with an ICD-10 diagnosis of anorexia nervosa, restricting type (AN-R), anorexia nervosa, binge-purge type (AN-BP), and bulimia nervosa (BN), treated at the child and adolescent inpatient department of the University Hospital in Berlin, Germany, between 1990 and 2015. Across and within ED subgroups, lifetime NSSI prevalence, methods of self-harm, and clinical correlates were evaluated. Independent correlations of demographic and clinical factors with NSSI were identified via multivariable regression models.

RESULTS

Of 382 inpatients (median = 15.6 (range = 9-18) years, females = 97.1%), 21.5% reported lifetime NSSI, consisting of cutting = 86.6%, scratching = 12.2%, and hitting = 8.5%. NSSI was more frequent in BN (47.6%) and AN-BP (39.3%) than AN-R (8.3%) (Φ = 0.43). Across ED subgroups, NSSI was associated with a higher prevalence of psychiatric comorbidities (AN-R: Φ = 0.55; AN-BP: Φ = 0.69; BN: Φ = 0.78), suicidal ideation (AN-R: Φ = 0.30; AN-BP: Φ = 0.38; BN: Φ = 0.29), and psychiatric medication use (AN-R: Φ = 0.23; AN-BP: Φ = 0.64; BN: Φ = 0.60). In multivariable regression analyses, NSSI was independently associated with a higher prevalence of psychiatric comorbidities (AN-R: OR = 2.93 [1.42, 6.04]; AN-BP: OR = 2.67 [1.13, 6.31]; BN: OR = 3.75 [1.71, 8.23]). Additionally, independent correlates with NSSI in AN-R included a higher prevalence of suicidal ideation (OR = 0.21 [0.72, 0.64]) and less weekly weight gain (OR = 0.03 [0.02, 0.43]), while in BN, NSSI was correlated with longer inpatient treatment duration (OR = 1.01 [1.00, 1.02]).

CONCLUSIONS

There is a high lifetime prevalence of NSSI among youth with AN and BN requiring inpatient treatment, especially those with binge-purge behaviors. Treatment programs must be tailored to address psychiatric comorbidities and suicidality to improve patient care and suicide prevention.

TRIAL REGISTRATION

This study was not considered a clinical trial but a retrospective chart review based on routinely assessed clinical parameters. The study includes data from human participants, however: (1) no intervention and no prospective assignment to interventions were performed, and (2) no evaluation of an intervention on participants was accomplished.

Altered Resting-State Networks in Adolescent Non-Suicidal Self-Injury - A Graph Theory Analysis

Non-suicidal self-injury (NSSI) is a highly prevalent transdiagnostic symptom and risk marker for mental health problems among adolescents. Research on the neurobiological mechanisms underlying NSSI is needed to clarify the neural correlates associated with the behavior. We examined resting-state functional connectivity in n = 33 female adolescents aged 12–17 years engaging in NSSI, and in n = 29 age-matched healthy controls using graph theory. Mixed linear models were evaluated with the Bayes Factor to determine group differences on global and regional network measures and associations between network measures and clinical characteristics in patients. Adolescents engaging in NSSI demonstrated longer average characteristic path lengths and a smaller number of weighted hubs globally. Regional measures indicated lower efficiency and worse integration in (orbito)frontal regions and higher weighted coreness in the pericalcarine gyrus. In patients, higher orbitofrontal weighted local efficiency was associated with NSSI during the past month while lower pericalcarine nodal efficiency was associated with suicidal thoughts in the past year. Higher right but lower left pericalcarine weighted hubness was associated with more suicide attempts during the past year. Using a graph-based technique to identify functional connectivity networks, this study adds to the growing understanding of the neurobiology of NSSI.

Associations of depressive and anxiety symptoms with non-suicidal self-injury and suicidal attempt among Chinese adolescents: The mediation role of sleep quality

BACKGROUND

Associations of depressive and anxiety symptoms with non-suicidal self-injury (NSSI) and suicide attempt (SA) are not well understood. We aimed to examine these associations among Chinese adolescents, and whether any potential association is mediated through sleep quality.

METHODS

We conducted a cross-sectional study among 1,771 (994 boys [56.1%] and 777 girls [43.9%], mean [SD] age was 12.9 [0.6] years) adolescents who participated in the baseline survey of the Chinese Adolescent Health Growth Cohort (CAHGC) study. Depressive symptoms, anxiety symptoms, NSSI, SA and sleep quality were measured by validated questionnaire. Logistic regression models were employed to estimate the associations of depression and anxiety with NSSI and SA. Mediation analyses were conducted to explore the mediate effect of sleep quality.

RESULTS

The 12-month prevalence of NSSI and SA was 17.1 and 8.3%, respectively. Depressive and anxiety symptoms were significantly associated with NSSI (the adjusted odds ratio [aOR] was 1.89 [95% CI 1.34-2.65] for depressive symptoms and 2.84 [95% CI 2.05-3.94] for anxiety symptoms) and SA (the aOR was 3.20 [95% CI 2.03-5.05] for depressive symptoms and 2.98 [95% CI 1.84-4.84] for anxiety symptoms). No significant gender differences were found in the associations. The mediation proportion of sleep quality on the association of depressive and anxiety symptoms with NSSI, as well as depressive and anxiety symptoms with SA were 21.1, 13.9, 13.6, and 14.7, respectively.

CONCLUSION

Independent associations of depressive and anxiety symptoms with NSSI and SA were observed in Chinese adolescents, and there were no significant gender differences in the associations. Moreover, these associations were partially mediated through sleep quality. Targeted interventions for adolescents' NSSI and SA should focus on those who have depressive and anxiety symptoms, and poor sleep quality.

[A Multidimensional Assessment of Emotion Regulation in Adolescent Non-Suicidal Self-Injury]

The ability to regulate one's emotions (emotion regulation, ER) with regard to individual short- and long-term goals presents one of the most central human skills. A disrupted development of ER skills is associated with psychopathological outcomes. Non-suicidal self-injury (NSSI) presents a frequent and impairing phenomenon among young individuals. Disruptions regarding various aspects of ER are involved in the development and maintenance of NSSI. In the present study, we examined ER from a multidimensional perspective, including a sample of female adolescents meeting DSM-5 criteria for NSSI disorder (N = 30) and a psychologically healthy control group (N = 30). In line with results from previous studies, female adolescents with NSSI exhibited considerable difficulties regarding all aspects of ER investigated. Furthermore, various aspects of ER were distinctly linked with depressive and BPD symptomatology. Differences in NSSI frequency between participants largely went back to difficulties regarding specific aspects of ER, in combination with the self-rated severity of exposure to early life maltreatment. With regard to clinical practice, the use of interventions to improve particular aspects of ER, under simultaneous consideration of the individual developmental history and psychopathological impairment, might provide an efficient approach to mediate long-lasting change in the treatment of deliberate self-harm.

The interpersonal processes of non-suicidal self-injury: A systematic review and meta-synthesis

BACKGROUND

Understanding the processes underlying non-suicidal self-injury (NSSI) is important given the negative consequences of this behaviour. Qualitative research has the potential to provide an in-depth exploration of this. There has been limited research regarding the interpersonal processes associated with NSSI; therefore, a meta-synthesis was conducted to investigate this.

METHODS

A search of PsycINFO, MEDLINE, Web of Science, and CINAHL electronic databases from date of inception to November 2020 was conducted. In total, 30 papers were included in the final review. A meta-ethnographic approach was utilized to synthesize the data.

RESULTS

Two overarching themes were found. Within 'Powerful relational dynamics', NSSI was cited as a response to participants becoming stuck in aversive or disempowering relational positions with others. Within the 'Taking matters into their own hands' subtheme, NSSI was reported as a way for participants to get interpersonal and emotional needs met.

LIMITATIONS

Several included papers did not comment on the researcher-participant relationship, which may have affected qualitative results. A small number of potentially eligible papers were unavailable for synthesizing.

CONCLUSION

Findings provide a more nuanced investigation of the interpersonal processes underlying NSSI. Consistent with relevant theories, NSSI appears to be a way of mitigating difficult interpersonal experiences or getting interpersonal needs met. NSSI may be engaged in as a substitute to other, less damaging ways to cope. An argument is made for a more empathetic understanding of NSSI and the use of relational interventions.

PRACTITIONER POINTS

Self-injury may occur in response to interpersonal stressors Self-injury can be a means to get interpersonal needs met Self-injury may replace other means of coping that become blocked or thwarted Emotional distress can be closely linked with interpersonal factors for this group Relational therapies may be beneficial where interpersonal processes are linked to NSSI.

Advancing a temporal framework for understanding the biology of nonsuicidal self- injury: An expert review

Nonsuicidal self-injury (NSSI) is a serious clinical problem, particularly for adolescents and young adults. NSSI is a complex behavior that emerges through the intersecting effects of social, psychological, and biological mechanisms. Although the social and psychological contributions to risk for developing NSSI are relatively well understood and have guided the development of effective psychosocial treatments for self-injury, the biological mechanisms underlying NSSI have just begun to come to light. To evaluate and categorize the biological research conducted on the topic of NSSI, we propose a model that distinguishes between trait and state markers. According to this model, risk factors and mechanisms involved in NSSI can be distinguished into both trait and state factors. We review the existing evidence on distal biological traits (predictors) of NSSI, proximal biological traits (correlates) of NSSI, and biological states directly preceding or following NSSI. We conclude by providing recommendations for future research on the neurobiology of NSSI.

Non-Suicidal Self-Injury: An Observational Study in a Sample of Adolescents and Young Adults

Non-Suicidal Self-Injury (NSSI) is the self-inflicted destruction of body tissues without suicidal intent with a prevalence of 1.5% to 6.7% in the youth population. At present, it is not clear which emotional and behavioral components are specifically associated with it. Therefore, we studied NSSI in a clinical sample of youth using the Ottawa Self-injury Inventory and the Barratt Impulsiveness Scale 11. The Mann-Whitney test was used to compare the numerical responses provided to the tests. We found 54 patients with NSSI, with a mean age of 17 years. Scores were analyzed in the total sample and in four subgroups. In the total sample, Internal Emotion and External Emotion Regulation, Craving, Non-Planning and Total Impulsivity were significantly associated with NSSI. There were statistically significant differences in Craving between patients with multiple NSSI episodes, suicide attempts and multiple injury modes and patients of other corresponding subgroups, in Internal Emotion Regulation, Sensation Seeking and Motor Impulsivity between NSSI patients with suicide attempts and no suicide attempts, and in Cognitive Impulsivity between NSSI patients with multiple injury modes and one injury mode. It is necessary to carefully evaluate the components underlying NSSI in order to activate personalized treatment options.

Early maladaptive schemas in young people who self-injure

BACKGROUND

There is emerging evidence that early maladaptive schemas (EMS) may be a cognitive vulnerability factor in nonsuicidal self-injury (NSSI). The current study sought to examine the relationship between EMS and NSSI history, and whether this is moderated by gender, in a community youth sample.

METHOD

Participants were 403 Australian secondary and university students aged between 16 and 25 years, who completed a survey of NSSI history, EMS, and general emotional distress.

RESULTS

Logistic regression analysis indicated that being female, depression, and EMS scores were useful for differentiating between youth reporting NSSI history and those who did not. High levels of Defectiveness/Shame and Abandonment/Instability schema scores, and low levels of Emotional Inhibition schema scores, were associated with NSSI history. Gender did not moderate the relationships between these EMS scores and NSSI history.

CONCLUSIONS

Present results suggest that aspects of the schema domain of Disconnection and Rejection are important for identifying NSSI history beyond young people's emotional distress. This provides researchers and clinicians with an opportunity to better target key EMS, especially beliefs about self-defectiveness and feelings of shame, that may be driving the regulatory function of self-injury among youth.
