Do styles of emotion dysregulation differentiate adolescents engaging in non-suicidal self-injury from those attempting suicide?

Longitudinal Associations Between Nonsuicidal Self-Injury, Depressive Symptoms, Hopelessness, and Emotional Dysregulation in Adolescents

Nonsuicidal self-injury (NSSI) in adolescents has been associated with increased depressive symptomatology, hopelessness, and emotional dysregulation; however, few studies have examined longitudinal associations between NSSI and these problems. This study examines the longitudinal relationships among these variables in community adolescents and whether the pattern of relationships varies between boys and girls. The participants were 785 adolescents (57.1% girls) aged 13 to 18 years (M = 15.64; SD = 1.08) who completed self-reported measures of NSSI, depression, hopelessness, and emotional dysregulation at least once at two moments separated by 1 year. The longitudinal model was tested through structural equation modeling and multiple group analysis. NSSI predicted increased depressive symptoms, hopelessness, and emotional dysregulation; depressive symptoms predicted NSSI; hopelessness predicted depressive symptoms; and emotional dysregulation predicted depressive symptoms and hopelessness. The pattern was similar for girls and boys, although girls scored higher on all variables. The results underscore the important bidirectional associations between NSSI and other risk factors throughout adolescence. These findings will support prevention and interventions for NSSI and internalizing symptoms in adolescents in school and clinical settings.

Non-suicidal Self-injurious Thoughts and Behaviors Among Adolescent Inpatients

Non-suicidal self-injury (NSSI) is a serious public health concern that typically onsets during early adolescence. Adolescents (N = 980, ages 12-19 years) admitted for acute, residential psychiatric treatment completed baseline clinical interviews assessing mental disorders and questionnaires measuring demographics, early life adversity, and symptom severity. Prevalence rates of NSSI for lifetime (thoughts: 78%; behaviors: 72%), past year (thoughts: 74%; behaviors: 65%), and past month (thoughts: 68%; behaviors: 51%) were high. Although effect sizes were modest, the presence of a lifetime depressive disorder, sexual abuse, and comorbidity (i.e., three or more current disorders) were significant correlates of experiencing NSSI thoughts and behaviors. Furthermore, lifetime depressive disorder, current anxiety disorder, and comorbidity were associated with a greater odds of persistent NSSI thoughts and/or behaviors. Longitudinal studies are needed to determine whether targeting these factors reduces the persistence of NSSI thoughts and behaviors.

A machine learning algorithm-based model for predicting the risk of non-suicidal self-injury among adolescents in western China: A multicentre cross-sectional study

The prevalence of non-suicidal self-injurious (NSSI) in adolescents is high. However, few studies exist to predict NSSI in this population. This study employed a machine learning algorithm to develop a predictive model, aiming to more accurately assess the risk of NSSI in Chinese adolescents. Sociodemographic, psychological data were collected in 50 schools in western China. We constructed eXtreme Gradient Boosting (XGBoost) model and multivariate logistic regression model to predict the risk of NSSI and nomograms are plotted. Data from 13,304 adolescents were used for model development, with an average age of 13.00 ± 2.17 years; 617 individuals (4.6 %) reported non-suicidal self-injury (NSSI) behaviors. The results of the XGBoost model showed that depression and anxiety were the top two predictors of NSSI in adolescents. The results of the multivariate logistic regression model showed that the risk factors for adolescent NSSI behaviors include: gender (being female), Age, Living with whom (father), History of psychiatric consultation, Stress, Depression, Anxiety, Tolerance, Emotion abreaction. The XGBoost prediction and multivariate logistic regression model showed good predictive ability. Nomograms can serve as clinical tools to assist in intervention measures, helping adolescents reduce NSSI behaviors and improve their mental and physical well-being.

Distress tolerance and lifetime frequency of non-suicidal self-injury (NSSI): A systematic review and meta-analysis

NSSI has recently been recognized as a significant health issue given its documented association with psychopathology and across a broad spectrum of psychiatric disorders. It has been found that individuals experiencing heightened emotions, which is referred to as an emotional cascade, are more likely to engage in self-injury behaviour due to low levels of distress tolerance (DT). The current meta-analysis using PRISMA guidelines sought to quantify the strength of the association between DT and lifetime frequency of NSSI using 22 eligible studies (N = 14,588; F = 60.7%; age = 23.35 ± 7.30), mainly from the United States. The correlation between emotional DT and NSSI was a small negative correlation (r = -.14), and it was non-significant for behavioural DT and NSSI (r = .02). Also, the effect-size was significant for studies that used interview-based measure of NSSI (r = -.24), and it was non-significant when self-report measures of NSSI (r = -.11) utilized. The association between DT and NSSI was significant and negative across the general population (r = -.47), university students (r = -.17), and inpatients (r = -.27); surprisingly, it was significant and positive among adolescents or high school students (r = .17). The observed effect-sizes were independent of publication year, mean age and its standard deviation, study quality, female proportion, DT, NSSI measures reliability, and clinical status. Future studies on NSSI should consider DT as a spectrum from distress intolerance to distress over-tolerance, given that it seems it has different functions when different samples (e.g., adolescents) are studied.

Emotion dysregulation and mindfulness in non-suicidal self-injury

This study examined the association between mindfulness and engagement in non-suicidal self-injury (ENSSI) and whether emotion dysregulation explains this association. A secondary objective was to explore the difference between participants who engaged in a suicide attempt and those who only engaged in non-suicidal self-injury. A sample of 201 psychiatric patients (62.7% female; age range: 18-71 years old) participated in the study. The path analysis indicated that trait mindfulness was negatively associated with all emotion dysregulation dimensions and that one of these dimensions, impulse control difficulty, was associated with higher ENSSI. Moreover, impulse control difficulty was associated with increased odds of having attempted suicide. These findings suggest that mindfulness is a relevant construct to ENSSI with and without a suicide attempt. Future studies should investigate mindfulness-based interventions for ENSSI and the role played by the capacity to control impulses when experiencing negative emotions.

Adverse clinical outcomes among youths with nonsuicidal self-injury and suicide attempts: a longitudinal cohort study

BACKGROUND

More knowledge about risks of clinical outcomes associated with nonsuicidal self-injury (NSSI) and suicide attempts (SAs) is needed to inform risk assessment and intervention.

METHODS

Longitudinal cohort study based on 1,855 youths was clinically assessed for NSSI and SA, and followed up (from December, 2011 to December 2013) for the outcomes; diagnosed self-injury, alcohol/substance use disorder, and psychiatric inpatient care data derived from Swedish registers. Hazard ratios (HRs) and 95% confidence intervals (CIs) of the outcomes were estimated with Cox regressions, and additionally adjusted for the potential effect of sex and the number of clinical assessments. NSSI and SA were treated as time-varying covariates.

RESULTS

Youths with NSSI had elevated risks of all outcomes, compared with youths without NSSI or SA; the HR was 2.3, 95% confidence interval [1.6, 3.4] for self-injury, 1.4 [0.9, 2.1] for alcohol/substance use disorder, and 1.3 [1.0, 1.7] for psychiatric inpatient care. Youths with SA displayed higher risks for the outcomes than the NSSI group; the HR was 5.5 [2.4, 12.6] for self-injury, 2.0 [0.9, 4.4] for alcohol/substance use disorder, and 2.6 [1.5, 4.5] for psychiatric inpatient care. Youths with both NSSI and SA showed similar risks as youths with SA; HR 4.1 [2.0, 8.3] for self-injury, 2.0 [1.1, 4.1] for alcohol/substance use disorder, but a higher risk of psychiatric inpatient care; HR 5.0 [3.1, 7.9]. All results remained virtually unchanged in the adjusted analyses.

CONCLUSIONS

Youths with NSSI and/or SA had higher risks for subsequent adverse clinical outcomes. These excess risks were more pronounced among youths with SA and youths with both NSSI and SA, and the risk for psychiatric inpatient care was particularly high in youths with both NSSI and SA. Our findings suggest that early interventions for youths with NSSI or SA should not exclusively focus on suicide prevention, but also consider the risk of subsequent alcohol/substance use disorder.

Neural correlates of affective theory of mind in medication-free nonsuicidal self-injury: An fMRI study

Emerging evidence indicates that emotion processing deficits are associated with nonsuicidal self-injury (NSSI). However, limited attention has been paid to the socio-affective functions of NSSI. In this study, we aimed to investigate the affective theory of mind (ToM) in medication-free individuals engaging in NSSI at both behavioral and neural levels. Twenty-eight individuals (mean age = 22.96 years) who engaged in NSSI and 38 age-, sex-, and IQ-matched controls (mean age = 22.79 years) underwent functional magnetic resonance imaging while performing the "Reading the Mind in the Eyes Test" (RMET). All participants also completed the Difficulties in Emotion Regulation Scale (DERS), Toronto Alexithymia Scale (TAS-20), and Beck Scale for Suicide Ideation (BSI). Although we did not find significant group differences in the RMET performance, the NSSI group, relative to the controls, exhibited significantly greater left medial superior frontal lobe activation and decreased right angular gyrus activation than did the control group. Reduced right angular gyrus activity was related to higher DERS and TAS scores across all participants. Our findings provide new evidence for aberrant neural processing of affective ToM in self-injurers. Future studies in developing intervention protocols for NSSI should focus on the multifaceted phases of socio-affective processing.

Emotional Reactivity and Inhibitory Control in Nonsuicidal Self-Injury Adolescence: Divergence Between Positive and Negative Emotions

Nonsuicidal self-injury (NSSI) is prevalent in adolescents and is often linked to emotion dysregulation. However, it remains unknown which specific processes of emotion regulation and under what emotional context these processes are related to the risk for NSSI in samples of community-based adolescents. This study used two laboratory tasks to examine whether adolescents with a history of NSSI displayed difficulties in emotional reactivity and inhibitory control in response to negative and positive emotions. In Study 1, adolescents with/without a history of NSSI (N = 64; M_Age = 13.45 ± 0.50; 53% female) completed a picture perception task in which they were asked to judge the valence and arousal of images. In Study 2, adolescents with/without a history of NSSI (N = 74; M_Age = 13.49 ± 0.80; 50% female) were given a two-choice emotional oddball task that required them to differentially respond to frequent stimuli (images of an object) and infrequent stimuli (affective images). The results showed that adolescents with a history of NSSI showed decreased emotional sensitivity and lower levels of inhibitory control in response to images depicting negative emotional content but not to those depicting positive emotional content. Furthermore, affective inhibitory control problems were significantly positively related to the severity of NSSI, especially in the context of negative emotions. These findings suggest that there is a divergence between positive and negative emotions in both emotional reactivity and affective inhibitory control processes on NSSI. Specifically, relative to adolescents with no history of NSSI, adolescents with a history of NSSI showed lower emotional awareness and behavioral inhibitory control when processing negative emotions, but these distinctions were not found in contexts involving positive emotions. Additionally, the results suggest that affective inhibitory control deficits specific for negative emotions may result in vulnerability to increased NSSI severity.

Mental Health Difficulties Related to Suicidal Behavior in Adolescents: The Moderating Role of Self-Esteem

OBJECTIVE

The objective was to analyze the moderating effect of self-esteem on the relationship between mental health difficulties and suicidal behavior in adolescence.

METHOD

The sample was composed of 1,790 Spanish adolescents (M = 15.70 years; SD = 1.26; 53.7% girls) through a stratified random sampling by cluster at classroom level. The participants completed questionnaires about emotional symptoms, behavioral problems, peer relationship difficulties, hyperactivity, suicidal behavior, and self-esteem.

RESULTS

The results evidenced gender differences, showing that girls tend to have more emotional symptoms (t = -15.27; p ≤ .001; d = -0.71), more difficulties in peer relationship (t=-2.49; p = .013; d = -0.12) and less self-esteem (t = 12.15; p ≤ .001; d = 0.57), as well as more suicidal behaviors (t = -5.36; p ≤ .001; d = -0.25) than boys. It is also noted that emotional and behavioral difficulties influence suicidal behavior (R² = 0.35; ΔF = 197.42; p ≤ .001). In addition, self-esteem appeared to act as a protective factor, buffering the relationship between emotional and behavioral problems and suicidal behavior (R² = 0.39; F = 376.92; p ≤ .001).

CONCLUSIONS

Adolescents who present mental health difficulties might commit suicidal behavior if they have an unfavorable attitude toward themselves. However, the risk of committing suicidal behavior decreases if their attitude toward themselves is favorable. Thus, the development of self-esteem may be included in intervention programs for the prevention of suicidal behavior.HIGHLIGHTSGirls present more suicidal behaviors and less self-esteem than boys.Mental health difficulties influence the appearance of suicidal behavior.Self-esteem moderates the relationship between emotional problems and suicidal behavior.

Parents' lived experience of adolescents' repeated non-suicidal self-injury in China: a qualitative study

BACKGROUND AND OBJECTIVES

The prevalence of non-suicidal self-injury (NSSI) is high among adolescents. Parents have significant impact on the development of NSSI. Many quantitative studies have demonstrated the relationship between parental factors such as parenting behaviors and adolescents' NSSI. However, few studies have explored parents' responses and adolescent-parent reciprocal interaction during repeated NSSI. This study aimed to explore parents' cognition, behaviors and adolescent-parent reciprocal interaction during repeated NSSI.

METHODS

This is a phenomenological study. By purposive sampling, 24 parents of adolescents with repeated NSSI were recruited from a child and adolescent psychiatric ward in a mental health center in Chengdu, China. Semi-structured interviews were conducted and audio-recorded. Audio-recordings were transcribed verbatim and analyzed using thematic analysis.

FINDINGS

Three themes were identified: parents' attribution, perceptions and coping behaviors of NSSI. Chronic stress of adolescents and triggers of NSSI were associated with parental expectations. Parents initially perceived NSSI as a manifestation of puberty, a way of making needs met or a coping strategy of negative emotions, and gradually realized that it was a condition requiring psychological assistance. Parents' coping behaviors of NSSI were divided into 4 stages, namely denial, dissuasion, reflection and adaptation, and working as a team. To be more specific, parents' coping strategies at dissuasion stage included criticizing and conciliating, while those at reflection and adaptation stage included neglecting, avoiding conflicts and increasing control.

CONCLUSIONS

These findings suggest that adjusting parents' expectation and negative perceptions of NSSI is beneficial to reduce adolescent-parent conflict and adolescents' inner conflict and prevent NSSI. Furthermore, it's necessary to publicize NSSI related knowledge to promote the early detection and treatment 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.
