RESUMEN

Sexual minoritized individuals engage in non-suicidal self-injury (NSSI) at higher rates than their heterosexual peers. Disclosing one's sexual minoritized identity can put one at risk for experiencing discrimination, which is linked to greater engagement in NSSI. However, discrimination has yet to be tested as a mechanism linking sexual identity disclosure to NSSI. Understanding how sexual identity disclosure impacts NSSI has the potential to inform interventions to reduce sexual orientation disparities in NSSI. To address this gap, the current study examined sexual orientation-based discrimination as a mediator of the longitudinal association between sexual identity disclosure and NSSI among 792 sexual minoritized young adults. Higher levels of disclosure at baseline were associated with greater likelihood of NSSI at two-month follow-up via greater discrimination at one-month follow-up, even after controlling for baseline levels of depression and demographic characteristics. The indirect effect became non-significant after controlling for previous levels of discrimination and NSSI. Findings provide partial support for the hypothesis that identity disclosure may precede exposure to discrimination and, in turn, engagement in NSSI. However, identity disclosure does not appear to predict acute increases in discrimination. Future research is encouraged to examine these prospective associations with longer intervals between assessments, as the indirect effect of identity disclosure on NSSI via discrimination may continue to accumulate over time. Findings highlight the need to reduce discrimination following sexual identity disclosure through the implementation of equitable and affirmative practices in school, healthcare, and other settings to improve the well-being of sexual minoritized young adults.

RESUMEN

BACKGROUND: Non-suicidal self-injury (NSSI) is a significant public health concern among adolescents with major depressive disorders (MDD). Although previous research has linked child maltreatment (CM) to NSSI, the precise mechanisms remain unclear. This study aims to investigate the association between CM, cognitive reappraisal (CR), negative coping styles (NC) and NSSI in adolescents with MDD, from the perspectives of both Latent Variable Theory and the Network Theory of Mental Disorder. METHODS: A sample of 651 adolescents with MDD was recruited from January to December 2023. Data on CM, CR, NC, and NSSI were collected through paper-based self-reported questionnaires. Data analysis primarily involved structural equation modeling and network analysis. RESULTS: The reporting rate of NSSI among adolescents with MDD was 48.2%. CM showed a significant positive correlation with NSSI. NSSI was affected by CM through three paths: the mediating role of CR, the mediating role of NC, and the chain mediating role of both CR and NC. Emotional abuse (EA) was the central node, while NSSI, EA, and "The urge to cry quietly when faced with troubles"(NC10) were the key bridge nodes. CONCLUSIONS: This study is the first to use both structural equation modeling and network analysis to explore the explore the relationship between CM, CR, NC, and NSSI in adolescents with MDD, providing a theoretical basis for future early prevention and targeted interventions for adolescents with MDD.

RESUMEN

Engagement in nonsuicidal self-injury (NSSI) often begins in adolescence, and commonly occurs when a person is emotionally dysregulated. Parental emotion socialization (ES) plays a key role in shaping children's emotional expression, experience, and regulation. Longitudinal work is needed to understand how links between parental ES and adolescent clinical outcomes unfold over time. In this longitudinal study (N = 118; all assigned female at birth with a range of NSSI - from none to severe; age 12-17 years, Mage = 14.98 at the first assessment), for the Time 1 (T1) and Time 2 (T2) annual assessments; adolescents reported NSSI and adolescents and parents reported depressive symptoms. Parents (primarily mothers) reported on their supportive and unsupportive ES responses to youth expressions of sadness, anger, and happiness. We examined (1) concurrent relationships across time points, (2) longitudinal models (T1 to T2 change in parental ES and its associated T1 to T2 changes in adolescent clinical outcomes), and (3) prediction models (T1 parental ES predicting changes in adolescent clinical outcomes). Concurrent associations between parental supportive ES responses to sadness and anger were inversely related to adolescent's depressive symptoms and NSSI episodes. Longitudinal analyses showed that increases in unsupportive responses to sadness correspond with increases in depressive symptoms from T1 to T2. The findings underscore the importance of examining how parents respond to their children's emotions. Next steps are to investigate potential mechanisms of risk and consider interventions that enhance adaptive responses of parents to adolescents embroiled in negative emotional states.

RESUMEN

Previous research has provided clues to the association between bullying victimization, non-suicidal self-injury (NSSI), and psychotic-like experiences (PLEs). However, these studies have been limited in their failure to examine both the directions of the associations and the underlying mediating mechanisms. Furthermore, there has been little investigation into the longitudinal associations among these variables in rural adolescents. This study aimed to address the aforementioned limitations by examining the bidirectional associations and the potential mediating mechanisms among bullying victimization, NSSI, and PLEs in a sample of Chinese rural adolescents. A total of 526 junior middle school students (42.6% males; average age = 14.62, SD = 1.15, age range = 12 to 16 years old) from a rural county in Guangdong province, China were recruited and assessed at three time points spanning one year. Cross-Lagged Panel Models (CLPMs) were employed to investigate the prospective focal longitudinal associations. CLPMs revealed that notable reciprocal associations were observed between bullying victimization and NSSI, as well as between NSSI and PLEs. Moreover, PLEs at Time 1 significantly predicted bullying victimization at Time 2. Additionally, only the indirect path from Time 1 PLEs to Time 3 bullying victimization via Time 2 NSSI was significant. This study sheds light on the bidirectional associations and underlying mediating mechanisms among bullying victimization, NSSI, and PLEs in rural adolescents. The findings highlight the importance of considering the complex interplay between these factors and the need for targeted interventions to address the mental health concerns in this population.

RESUMEN

OBJECTIVE: Self-injurious behavior (SIB) can occur in the setting of many neurologic disorders that are amenable to deep brain stimulation (DBS). Although certain brain targets are believed to be particularly effective for SIB, improvements in the primary neurologic condition may also reduce co-occurring SIB. We performed a systematic review and meta-analysis of individual participant data to characterize the effects of DBS across various neurologic disorders and brain targets on comorbid SIB. MATERIALS AND METHODS: A systematic review of all available literature on DBS in treating disorders with co-occurring SIB was conducted in accordance with Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. Individual participant data were extracted and standardized mean differences (SMDs) in metrics of SIB severity and/or frequency were calculated for meta-analysis. Demographic variables and adverse events were also collated. RESULTS: Data from 59 patients, identified from 24 articles, with comorbid SIB who underwent DBS for various indications were extracted. The primary neurologic diagnoses included Tourette syndrome (n = 40), dystonia (n = 7), epilepsy (n = 5), acquired brain injury (n = 3), dyskinesia (n = 2), and obsessive-compulsive disorder (n = 2). Overall, DBS was highly effective in treating comorbid SIB (Mean SMD = -2.4, p < 0.0001) across primary disorders and intracranial targets. Patients with dystonia and DBS targeting the posterior hypothalamus had relatively less success at mitigating comorbid SIB. CONCLUSIONS: In patients with comorbid SIB, DBS to treat the primary neurologic condition may also mitigate SIB. Although several targets are emerging for the treatment of severe SIB, this work suggests that DBS targeting the primary neurologic condition should be first considered in comorbid SIB.

RESUMEN

BACKGROUND: Adolescence is a critical period for brain development, consolidation of self-understanding, and onset of non-suicidal self-injury (NSSI). This study evaluated the RDoC (Research Domain Criteria) sub-construct of Self-Knowledge in relation to adolescent NSSI using multiple units of analysis. METHODS: One hundred and sixty-four adolescents assigned female at birth (AFAB), ages 12-16 years with and without a history of NSSI entered a study involving clinical assessment and magnetic resonance imaging (MRI), including structural, resting-state functional MRI (fMRI), and fMRI during a self-evaluation task. For imaging analyses, we used an a priori defined Self Network (anterior cingulate, orbitofrontal, and posterior cingulate cortices; precuneus). We first examined interrelationships among multi-level Self variables. We then evaluated the individual relationships between NSSI severity and multi-level Self variables (self-report, behavior, multi-modal brain Self Network measures), then conducted model testing and multiple regression to test how Self variables (together) predicted NSSI severity. RESULTS: Cross-correlations revealed key links between self-reported global self-worth and self-evaluation task behavior. Individually, greater NSSI severity correlated with lower global self-worth, more frequent and faster negative self-evaluations, lower anterior Self Network activation during self-evaluation, and lower anterior and posterior Self Network resting-state connectivity. Multiple regression analysis revealed the model including multi-level Self variables explained NSSI better than a covariate-only model; the strongest predictive variables included self-worth, self-evaluation task behavior, and resting-state connectivity. CONCLUSIONS: Disruptions in Self-Knowledge across multiple levels of analysis relate to NSSI in adolescents. Findings suggest potential neurobiological treatment targets, potentially enhancing neuroplasticity in Self systems to facilitate greater flexibility (more frequently positive) of self-views in AFAB adolescents.

RESUMEN

Objective: The current study sought to clarify the role of emotion reactivity in non-suicidal self-injury (NSSI) by examining three forms of emotion reactivity (physiological and self-reported trait and state reactivity) among a sample of young adults with or without a history of NSSI. Materials and methods: Seventy-six adults (M age = 20.97, 73.7% female) participated in a semi-structured clinical interview to determine NSSI history and completed a measure of trait emotion reactivity. Participants then provided state emotion reactivity ratings before and after a social rejection task, recovery period, and positive mood induction while physiological data was continuously recorded. Results: Although individuals with a history of NSSI perceived themselves to be more emotionally reactive, these participants were not more physiologically reactive, nor were their state reactivity ratings significantly different from individuals without a history of NSSI. Discussion: Results suggest increased emotionality in response to a stressor is within normal bounds and not unique to individuals with a history of NSSI, and provide implications for future research on the etiology and treatment of NSSI.

RESUMEN

Adolescence is a transitional stage between puberty and maturity. Significant alterations in brain chemistry and hormone activity cause mood swings and other psychological and physical symptoms. On their journey to adolescence, adolescents deal with complex emotions, moral dilemmas, sexual concerns, identity crises and particular societal expectations related to their upbringing. Impulsivity in adolescents is frequent and causes multiple issues. Impulsivity often lead towards non-suicidal self-injury (NSSI), which has devastating consequences, which are both physical and mental. Both impulsivity and NSSI have their roots in brain chemistry and its related functions. The aim of this special communication was to delve into brain chemistry through studying the function of neurotransmitters and brain areas in NSSI and impulsivity. Multiple papers were sought on the topic of neurochemistry and neuroanatomy. The results identified serotonin, dopamine and glutamate as the neurotransmitters responsible for NSSI and impulsivity. Dysregulation in these neurotransmitters lead to the presentation of NSSI and impulsivity. Other than the neurotransmitters, the brain areas identified were prefrontal cortex, medial prefrontal cortex and ventrolateral prefrontal cortex. The compiled results of this research would help individuals in understanding the neurotransmitters and the brain areas responsible. This would also help in generating awareness regarding the biological nature of the phenomenon as well, leading to less stigmatisation. The less stigmatisation towards these phenomena can help the affected individuals to seek help without any guilt or shame, along with support from society as well.

RESUMEN

Background: Non-suicidal self-injury (NSSI) is a worldwide mental health problem that deserves thorough investigation. This study aims to explore the effect of parenting styles, attachment to parents, and self-compassion on the occurrence of non-suicidal self-injury (NSSI) behavior in adolescents and whether these factors influence their recovery motivation. Methods: A total of 132 adolescents who had engaged in NSSI within the last year and 72 adolescents who had never engaged in NSSI were recruited from the Shenzhen Kangning Hospital and from primary and secondary schools and communities. Differences in the Hamilton Depression Scale (HAMD), Inventory of Parent and Peer Attachment (IPPA), Egma Minn av. Bardndosnauppforstran (EMBU), and Self-Compassion Scale (SCS) of participants were compared. A binary logistic model was established to measure the odds ratios of these variables on the occurrence of NSSI. In the NSSI adolescent sample, separate binary logistic models were created with NSSI impulse inhibition, NSSI resistance activity, and NSSI recovery motivation as dependent variables and with parenting styles, attachment to parents, and self-compassion as independent variables. Results: Compared with adolescents with no NSSI behavior, those who had engaged in NSSI within the past year had higher scores on the HAMD, as well as higher EMBU-negative father parental behavior (punishment, excessive interference, rejection, and overprotection), EMBU-negative mother parental behavior (excessive interference, rejection, and punishment), and SCS negative self-compassion scores. Moreover, adolescents with NSSI had lower EMBU-father emotional warmth, EMBU-mother emotional warmth, IPPA-attachment to father, IPPA-attachment to mother, and SCS positive self-compassion scores. Current depressive symptoms and maternal punishment are risk factors for NSSI in adolescents, while positive self-compassion was a protective factor. Positive self-compassion can positively predict NSSI impulse inhibition, NSSI resistance activity, and NSSI recovery motivation. However, we unexpectedly found that the father's emotional warmth negatively predicts NSSI resistance activity. Conclusion: This study found that positive self-compassion has a significant impact on the prevention of and recovery from NSSI behavior in adolescents.

RESUMEN

AIM: To explore nursing students' thoughts and feelings about self-injuring during their clinical practicums. BACKGROUND: Unfamiliar clinical environments pose challenges for nursing students, potentially leading to high levels of stress. When students find it difficult to cope with emotional triggers, some contemplate self-injury. Yet, it is rare to explore nursing students' thoughts and feelings related to self-injury during their clinical practicums. DESIGN: A phenomenological approach was used. METHODS: Purposive sampling was used and the participants were drawn from nursing students who graduated from universities in Taiwan. In-depth, semi-structured interviews were conducted from August to November 2023. Data saturation was reached after interviewing 15 participants. Colaizzi's seven steps and NVivo software were used for data analysis. RESULTS: Four themes and 14 subthemes emerged. They were: (1) Sensing an emotional crescendo: participants experienced anxieties about clinical educators, assignments, homework and the clinical practicums and these intensified across time. (2) Physical and mental dysregulation: participants experienced physical discomfort, psychological distress and negative thoughts when subjected to overwhelming pressures during their clinical practicums. (3) Unwholesome self-protective behaviors: participants expressed thoughts of self-injury, engaged in self-injurious behaviors, experienced suicidal ideations and attempted suicide as measures of relieving stress. (4) Compassionate self-protective behaviors: participants coped with stress through emotional voicing, modifying situations to adjust stress, reaching out for help, self-compassion and self-care. CONCLUSIONS: Findings raise awareness of the need for clinical educators to demonstrate empathy with nursing students who have thoughts of self-injury during their clinical practicums. Further, it is crucial for them to offer timely guidance on the healing process while simultaneously creating nurturing clinical environments wherein students could flourish and grow.

RESUMEN

Purpose: Non-suicidal self-injury (NSSI) is a growing public health concern among college students, with cybervictimization (CV) emerging as a significant contributing factor. Grounded in the experiential avoidance theory, this study investigates the mediating roles of cognitive fusion and negative emotions in the relationship between CV and NSSI, providing new insights into these key variables. Methods: A convenience sample of 457 undergraduate students (29% male; mean age 18.36±0.66 years) from two universities in Fujian Province participated in this study. Data were collected using the Cyberbullying Victimization Scale, Cognitive Fusion Questionnaire, Positive and Negative Affect Schedule, and Non-Suicidal Self-Injury Scale. Descriptive statistics and Pearson correlation analysis were conducted using SPSS 25.0, while the mediating effects were analyzed using Process 3.5. Results: (1) Significant positive correlations were found among CV, cognitive fusion, negative emotions, and NSSI (p < 0.01). (2) CV was directly associated with NSSI (ß = 0.22, p < 0.001) and positively predicted both cognitive fusion (ß = 0.17, p < 0.001) and negative emotions (ß = 0.15, p < 0.01). Additionally, cognitive fusion (ß = 0.16, p < 0.01) and negative emotions (ß = 0.11, p < 0.05) significantly predicted NSSI. (3) Mediation analyses revealed that cognitive fusion and negative emotions mediated the CV-NSSI relationship through three pathways: CV→cognitive fusion→NSSI (mediation effect = 0.026), CV→negative emotions→NSSI (mediation effect = 0.02), and CV→cognitive fusion→negative emotions→NSSI (mediation effect = 0.01). Conclusion: The study confirms that CV influences NSSI indirectly through cognitive fusion and negative emotions, supporting the experiential avoidance model. These findings underscore the importance of addressing cognitive and emotional processes in interventions aimed at reducing NSSI among college students.

RESUMEN

Non-suicidal self-injury (NSSI) among adolescents continues to be a significant public health concern worldwide. A recent systematic review and meta-analysis found that the global prevalence of NSSI in adolescents aged 12-18 years was 17.2%, with higher rates reported among females (19.7%) than males (14.8%). This behavior has been linked to several negative outcomes, such as depression, anxiety, substance abuse, and suicidal ideation. The present study aimed to classify adolescents based on intrapersonal and interpersonal factors associated with NSSI proposed in Nock's (2009) integrated model of NSSI, to identify distinct clusters targeting specific risk factors. This encompassed negative cognition, emotional vulnerability, poor coping skill, peer-victimization, family adaptability, and perceived stress. A total of 881 adolescents aged 11-16 years in South Korea completed self-reported questionnaires on automatic thoughts, depression, emotional regulation, peer victimization, family adaptability and perceived stress. Latent profile analysis (LPA) revealed three distinct classes: "the severe group", "the moderate group", "the mild group". Class 3 ("severe group": N = 127) exhibited greater severity related to NSSI, including negative cognition, emotional vulnerability, poor coping skills, peer victimization, and perceived stress, with weaker levels of factors that can prevent NSSI compared to class 1 ("mild group": N = 416) and class 2 ("moderated group": N = 338). The present study emphasizes the importance of considering both intrapersonal (e.g., negative automatic thoughts & emotional dysregulation) and interpersonal factors (i.e., peer victimization) when understanding NSSI - among adolescents. These findings can be utilized to develop interventions aimed at reducing the prevalence and severity of NSSI among adolescents.

RESUMEN

OBJECTIVE: This study aimed to investigate the relationship between non-suicidal self injury (NSSI), dissociative experiences, types of childhood traumas, and attachment styles in adolescents. METHOD: Adolescents aged 14-18 with a diagnosis of NSSI and a psychiatric disorder (NSSI, n=40), a clinical comparison group which have any psychiatric disorder without NSSI (CCG, n=40) and a healthy control group (HC, n=40) were included. The diagnosis of NSSI were confirmed with the research criteria of the Diagnostic and Statistical Manual of Mental Disorders-5th Edition. All participants were evaluated using the Kiddie Schedule for Affective Disorders and Schizophrenia - Present and Lifetime Version. Childhood Trauma Questionnaire (CTQ), the short form of the Inventory of Parent and Peer Attachment (IPPA), and the Adolescent Dissociative Experiences Scale (ADES) were used. RESULTS: The dissociation scores were higher in the NSSI group compared to the CCG group (4.8±2.0 and 2.9±2.2, p<0.001). NSSI group also had higher trauma levels but the difference was not statistically significant (48.0±14.2 and 41.4±5.0, p=0.062). Similarly, the NSSI group yielded higher scores of CTQ (48.0±14.2 and 33.8±6.8, p<0.001) and ADES (4.8±2.0 and 1.8±1.6, p<0.001) compared to HC group. Also, compared to the HC group, the NSSI group had more impaired attachment to father (42.0±19.7 vs. 53.0±21.7, p=0.056) and more frequently reported physical and emotional abuse. Finally, there were negative correlations between attachment levels to mother and CTQ total scores (r=-0.70, p<0.001) and between father attachment subscale and ADES scores (r=-0.33, p=0.047). CONCLUSION: Our study supports the notion that dissociation, trauma and insecure attachment are more common in individuals with NSSI. Psychotherapeutic approaches based on current findings will provide more benefits to patients.

RESUMEN

BACKGROUND: Attitudes toward risk and ambiguity significantly influence how individuals assess and value rewards. This fMRI study examines the reward valuation process under conditions of uncertainty and investigates the associated neural mechanisms in individuals who engage in nonsuicidal self-injury (NSSI) as a coping mechanism for psychological pain. METHODS: The study involved 44 unmedicated individuals who reported five or more NSSI episodes in the past year, along with 42 age-, sex-, handedness-, IQ-, and socioeconomic status-matched controls. During the fMRI scans, all participants were presented with decision-making scenarios involving uncertainty, both in terms of risk (known probabilities) and ambiguity (unknown probabilities). RESULTS: In the NSSI group, aversive attitudes toward ambiguity were correlated with increased emotion reactivity and greater method versatility. Whole-brain analysis revealed notable group-by-condition interactions in the right middle cingulate cortex and left hippocampus. Specifically, the NSSI group showed decreased neural activation under ambiguity v. risk compared to the control group. Moreover, reduced hippocampal activation under ambiguity in the NSSI group was associated with increased emotion regulation problems. CONCLUSIONS: This study presents the first evidence of reduced brain activity in specific regions during value-based decision-making under conditions of ambiguity in individuals with NSSI. These findings have important clinical implications, particularly concerning emotion dysregulation in this population. This study indicates the need for interventions that support and guide individuals with NSSI to promote adaptive decision-making in the face of ambiguous uncertainty.

RESUMEN

BACKGROUND: Non-suicidal self-injury (NSSI) is increasingly prevalent among patients with bipolar disorder (BD), raising concerns in psychology and mental health. Investigating the incidence and factors associated with NSSI is crucial for developing prevention and intervention strategies. METHODS: NSSI behaviors were identified using the Ottawa Self-injury Inventory. The Clinically Useful Depression Outcome Scale supplemented with questions for the DSM-5 specifier of mixed features (CUDOS-M) and the Mini International Neuropsychiatric Interview (Hypo-)Manic Episode with Mixed Features-DSM-5 Module (MINI-M) were used to evaluate clinical symptoms. Non-parametric tests, chi-square tests, point-biserial correlation and logistic regression analyses were employed for the purposes of data analysis. RESULTS: The enrolled sample comprised 1044 patients with BD from 20 research centers across China. Out of 1044 individuals, 446 exhibited NSSI behaviors, with 101 of them being adolescents, leading to a prevalence of 78.3 % among adolescent patients. The most common methods for females and males were "cutting" (41.2 %) and "hitting" (34.7 %), respectively. By binary logistic regression analysis, young age, female, bipolar type II disorder, with suicidal ideation and mixed states, depressive symptoms and without family history of mental disorder were correlates of NSSI in patients with BD (P < 0.05). LIMITATIONS: As a cross-sectional study, causality between NSSI behaviors and associated factors cannot be established. Reporting and recall biases may occur due to self-rating scales and retrospective reports. CONCLUSION: Our study indicates a concerning prevalence of NSSI, particularly among young patients with BD in China. Future research should focus on understanding NSSI behaviors in this population and developing effective interventions.

RESUMEN

BACKGROUND: Nonsuicidal self-injury (NSSI) is prevalent among emerging adults in post-secondary school, but little is known about change and stability in NSSI during the transition to university. Moreover, there has been limited person-centered work focusing on heterogeneity in NSSI engagement among students over time. The present study aimed to investigate the development and maintenance of NSSI across the first year of university and explore predictors of potential variability in trajectories of NSSI. METHODS: The present sample consisted of 1125 first-year university students at a large post-secondary institution (Mage = 17.96, 71 % female, 28 % male, 1 % gender diverse) who participated in a larger longitudinal study. Participants completed an online survey three times over their first year of university. Latent growth curve modeling (LGCM) in Mplus was utilized to explore different NSSI group trajectories across first year university. RESULTS: NSSI was prevalent among first year students (35 %). LGCM revealed one developmental trajectory; NSSI engagement decreased across the first year of university. Students who engaged in NSSI had increased difficulties with emotion regulation, lower self-compassion, and lower levels of social support compared to students who did not engage in NSSI. LIMITATIONS: The present study may be subject to recall errors and future studies should include more gender diverse samples to increase generalization of findings. CONCLUSIONS: Findings highlight the transition to university as a peak period of vulnerability for NSSI engagement and emphasize the need for proactive university intervention efforts to mitigate risk and improve student well-being.

RESUMEN

Objective: This study aimed to explore the impact of the COVID-19 pandemic on non-suicidal self-injury (NSSI) among youth students, and the mediating role of psychological factors in the relationship between the COVID-19 pandemic and NSSI. Method: An online survey was conducted at junior and senior high schools, as well as universities located in Jingzhou, Hubei Province, China between June 2021 and January 2022. The COVID-19 Impact Index was constructed using multiple correspondence analysis (MCA) method. The bootstrapping method was used for mediation analysis. Results: A total of 16025 youth participated in the study and 12507 youth (78.1%) finished the questionnaires. The COVID-19 Impact Index had a significantly positive effect on NSSI (r=0.16, p<0.001). The mediation analysis results showed that the COVID-19 Impact Index had a significant indirect effect on youth' NSSI (ß=0.0918, 95% CI [0.0788, 0.1048]), and this indirect effect was mainly achieved through affecting youth' anxiety, depression and post-traumatic stress disorder (PTSD). The mediation effect of anxiety on NSSI was 0.0584, the direct effect was 0.0334, and the mediation proportion was 63.6%. The mediation effect of depression on NSSI was 0.0668, the direct effect was 0.0250, and the mediation proportion was 72.8%. The mediation effect of PTSD on NSSI was 0.0640, the direct effect was 0.0278, and the mediation proportion was 69.7%. All the mediation effects, direct effects and total effects were statistically significant (p<0.001). Conclusion: The higher the impact of the COVID-19 Impact Index, the higher the prevalence of NSSI among youth students. Anxiety, depression and PTSD had mediated the relationship between the COVID-19 Impact Index and NSSI. It is suggested that specific health policies, mental health services and interventions should be developed to reduce the NSSI and improve mental health status among youth students during the COVID-19 pandemic.

RESUMEN

The multilevel psychosocial stressors associated with COVID-19 pandemic set the stage to investigate risk factors and groups susceptible for non-suicidal self-injury (NSSI). A national sample of 9,929 Brazilian adults aged 36.1 years on average participated in the study. Cross-sectional data were collected in 2020, 2021, 2022, and 2023. NSSI levels were considered high in the total sample (13.2%) when compared to other studies in this context. The variables with the highest explanatory power in the regression models were age, anxiety, and depression. The main risk factors were being younger, living in the South or Southeast regions of Brazil, having lower educational attainment, and having higher rates of anxiety and depression. Respondents had the highest probability of NSSI in 2022. The sustained higher rates of NSSI in 2023 compared to the beginning of the pandemic underscores the need for continuous monitoring and the development of preventive actions for self-injurious behaviors.

RESUMEN

Background: Both Internet addiction (IA) and non-suicidal self-injury (NSSI) are major public health concerns among adolescents, association between internet addiction and non-suicidal self-injury have been observed among adolescents. However, it is unclear how, and under what conditions, internet addiction relates to non-suicidal self-injury. According to our hypothesis, there is a positive relationship between IA and NSSI among Chinese adolescents, but this relationship is affected by the mediating role of loneliness and the moderating role of cognitive reappraisal. Method: A cross-sectional survey was conducted on 1046 Chinese adolescents from 3 middle schools. Measurements: Adolescent Self-Harm Scale; Young's Internet Addiction Test (IAT); University of California at Los Angels (UCLA) Loneliness Scale; Emotional Regulation Questionnaire (ERQ), They were asked to complete self-report questionnaires. Results: In our sample, the detection rate of NSSI was 12.3%. IA was positively associated with NSSI, and loneliness partially mediated the association between them. In addition, cognitive reappraisal moderated the first half path of the mediation model. Specifically, the higher the level of cognitive reappraisal, the weaker the positive effect of IA on NSSI through loneliness. Conclusion: Interventions targeted to reduce loneliness and increase cognitive reappraisal strategies may reduce the risk of NSSI in adolescents with Internet addiction.

RESUMEN

BACKGROUND: Self-directed violence (SDV) comprises both suicide and self-injury and represents a pressing problem among incarcerated persons. Negative impacts of SDV in correctional settings also extend to behavioral health clinicians (BHCs) (e.g., job turnover). Correctional SDV risk assessment and management standards include staff training as part of the comprehensive approach. The Core Competency Model for Corrections (CCM-C) is a novel, evidence-informed training program for BHCs covering both clinician self-management and clinical care skills. METHODS: This pilot trial is a type 3 hybrid implementation-effectiveness approach. It will employ a wait-list control sequential cross-over design. Participants (N = 50-100) will be BHCs employed by the North Carolina Department of Adult Corrections. Following stratification for years of clinical experience, BHCs will be randomly assigned to (1) a training group that receives CCM-C immediately and (2) a wait-list control receiving CCM-C approximately 6 weeks later. Electronically administrated survey evaluation will occur across baseline and two follow-up (i.e., 2 weeks after each training session) time points. DISCUSSION: The primary outcome is feasibility assessed through collaboration with a Corrections Advisory Panel and feedback from BHCs. Secondary effectiveness outcomes that will be evaluated over time include SDV-related knowledge, attitudes, stigma, and intent to use training content. We will examine a tertiary outcome, namely compassion fatigue. Clinical trial limitations and impacts are discussed. TRIAL REGISTRATION: Clinicaltrials.gov, NCT06359574. This study was registered on 04/05/2024.
