The Interactive Effect of Major Depression and Nonsuicidal Self-Injury on Current Suicide Risk and Lifetime Suicide Attempts

Risk prediction models for non-suicidal self-injurious behavior in patient with depressive disorder: a protocol for systematic review and mata-analyisis

INTRODUCTION

Non-suicidal self-injury (NSSI) frequently occurs in patients with depressive disorder and often presents as burning or severe scratching. NSSI plays a crucial role in increasing the risk of self-injury in individuals with depressive disorder. Despite the progressive development of various risk prediction models to identify NSSI, there are significant differences in their overall predictive performance. This systematic review aims to evaluate the quality and applicability of these models in predicting NSSI among patients with depressive disorders.

METHODS AND ANALYSIS

A systematic review with meta-analysis was conducted targeting patients with depressive disorder. We included studies on risk prediction models for NSSI behavior in this population that were developed and published. The primary outcome was NSSI behavior as reported by the prediction models. Predictive variables were measured at different disease stages in patients with depressive disorder, with no specific limitations on the prediction horizon. The intended use of the risk prediction model is to individualize the prediction of NSSI behavior of in patients with depressive disorder, thus facilitating the implementation of preventive measures to avoid adverse events. Databases, including China National Knowledge Infrastructure (CNKI), Wanfang Database, VIP Database, PubMed, Web of Science, Medline, and Embase, were searched from inception to March 2024 by two independently reviewers. Data extraction followed the guidelines outlined in the Checklist for Critical Appraisal and Data Extraction for Systematic Reviews of Prediction Modelling Studies (CHARMS). The risk of bias and applicability of the included studies were assessed using PROBAST. Descriptive statistical methods were employed to summarize the characteristics of the NSSI models and meta-analysis for model validation was conducted using Stata software.

CONCLUSION

The study will systematically review the prediction models for NSSI in patients with depressive disorders to enhance clinical practice. This research will also assist clinicians in selecting effective prediction models for NSSI in this patient population.

The association between nonsuicidal and suicidal self-injurious behaviors: A systematic review and expanded conceptual model

OBJECTIVES

Nonsuicidal self-injury (NSSI) is one of the strongest predictors of suicidal behavior. Despite this, the field still has a limited understanding of the mechanisms by which this relationship is conferred.

METHOD

We conducted a systematic review of the empirical research examining potential factors driving (i.e., moderators, mediators) the relationship between NSSI and suicidal behavior to address this gap in the literature.

RESULTS

We identified only 15 studies examining moderators or mediators of this relationship, examining 40 unique mediators and 22 unique moderators. Three prominent weaknesses were identified in the reviewed literature: (1) limited intersection with existing theoretical models of the NSSI - suicidal behavior relationship, (2) little replication of findings across studies (i.e., only four mediators and four moderators assessed in multiple studies), and (3) only one of the included studies utilized a prospective design. Research to date does little to improve our understanding of the theoretical or prospective relationship between NSSI and suicidal behavior, highlighting a foundational gap in the literature.

DISCUSSION

We propose the Nonsuicidal to Suicidal Self-Injury Pathway Model, a new conceptual model of the relationship between NSSI and suicidal behavior, drawing on extant theory and empirical research; we discuss future directions for work in this area.

An examination of the mediating role of maladaptive emotion regulation strategies in the complex relationship between interpersonal needs and suicidal behavior

Background

Studies have shown that psychological factors, notably interpersonal needs and emotion regulation, play a significant role in suicidal behavior. Interpersonal needs are significant contextual components that affect emotion regulation and contribute to a wide range of dysfunctional behaviors, such as suicidal behavior. It has been postulated that emotion regulation mediates the associations between proximal and distal risk factors of suicidal behavior.

Method

The sample consisted of 340 community-dwelling individuals (62.5% women; SD = 0.48) with an age range of 18 through 55 (M = 30.23; SD = 8.54) who completed the interpersonal needs questionnaire, the suicide behaviors questionnaire-revised, and the cognitive emotion regulation questionnaire. The Structural Equation Modeling (SEM) approach was utilized to evaluate a mediation model.

Results

The findings indicate that interpersonal needs (i.e., perceived burdensomeness r = .55, p <.01 and thwarted belongingness r = .25, p <.01) and putatively maladaptive cognitive emotion regulation strategies (i.e., self-blame; r = .38, p <.01, catastrophizing; r = .55, p <.01, rumination; r = .40, p <.01, and other blame; r = .44, p <.01) have strong associations with suicidal behavior, and these strategies have a mediating effect on the association between interpersonal needs and suicidal behavior.

Conclusions

Our findings show that contextual-interpersonal needs, which underpin suicidal behavior, are significantly influenced by maladaptive emotional processes. Thus, therapeutic outcomes might be enhanced by focusing on the content of the associated cognitions and trying to reduce maladaptive regulatory processes like rumination and catastrophization.

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.

Potential mechanisms of non-suicidal self-injury (NSSI) in major depressive disorder: a systematic review

Background

Non-suicidal self-injury (NSSI) is a frequent and prominent phenomenon in major depressive disorder (MDD). Even though its prevalence and risk factors are relatively well understood, the potential mechanisms of NSSI in MDD remain elusive.

Aims

To review present evidence related to the potential mechanisms of NSSI in MDD.

Methods

According to Preferred Reporting Items for Systematic Reviews and Meta-Analyses 2020 guidelines, articles for this systematic review were searched on Medline (through PubMed), Embase (through Elsevier), PsycINFO (through OVID) and Web of Science databases for English articles, as well as China National Knowledge Infrastructure (CNKI), SinoMed, Wanfang Data, and the Chongqing VIP Chinese Science and Technology Periodical (VIP) Databases for Chinese articles published from the date of inception to 2 August 2022. Two researchers (BW, HZ) independently screened studies based on inclusion and exclusion criteria and assessed their quality.

Results

A total of 25 157 studies were searched. Only 25 of them were ultimately included, containing 3336 subjects (1535 patients with MDD and NSSI, 1403 patients with MDD without NSSI and 398 HCs). Included studies were divided into 6 categories: psychosocial factors (11 studies), neuroimaging (8 studies), stress and hypothalamic-pituitary-adrenal (HPA) axis (2 studies), pain perception (1 study), electroencephalogram (EEG) (2 studies) and epigenetics (1 study).

Conclusions

This systematic review indicates that patients with MDD and NSSI might have specific psychosocial factors, aberrant brain functions and neurochemical metabolisms, HPA axis dysfunctions, abnormal pain perceptions and epigenetic alterations.

Suicide versus homicide firearm injury patterns on trauma systems in a study of the National Trauma Data Bank (NTDB)

Firearm related mortality in the USA surpassed all other developed countries. This study hypothesizes that injury patterns, weapon type, and mortality differ between suicide groups as opposed to homicide. The American College of Surgeons National Trauma Database was queried from January 2017 to December 2019. All firearm related injuries were included, and weapon type was abstracted. Differences between homicide and suicide groups by sex, age, race, and injury severity were compared using a Mann–Whitney test for numerical data and Fisher’s exact test for categorical data. The association between weapon type and mortality relative to suicide as opposed to homicide was assessed in Fisher’s exact tests. Significance was defined as p < 0.05. There were 100,031 homicide and 11,714 suicide subjects that met inclusion criteria. Homicides were mostly assault victims (97.6%), male (88%), African–American (62%), had less severe injury (mean (ISS) 12.07) and a median age of 20 years old (IQR: 14, 30, p < 0.01). Suicides were mostly male (83%), white (79%), had more severe injury (mean ISS 20.73), and a median age of 36 years old (IQR: 19, 54, p < 0.01). Suicide group had higher odds of head/neck (OR = 13.6) or face (OR = 5.7) injuries, with lower odds of injury to chest (OR = 0.55), abdominal or pelvic contents (OR = 0.25), extremities or pelvic girdle (OR = 0.15), or superficial soft tissue (OR = 0.32). Mortality rate was higher for suicide group (44.8%; 95% confidence interval (CI) 43.9%, 45.7%) compared to the homicide group (11.5%; 95% CI 11.3%, 11.7%). Suicide had higher mortality, more severe injuries, and more head/neck/facial injuries than homicide. Majority of suicides were with handguns.

Associations of Non-suicidal Self-Injury and Psychological Symptoms With Suicide Attempt in Adolescents: Are There Any Gender Differences?

Background

Psychological symptoms and non-suicidal self-injury (NSSI) are independently associated with suicide attempts (SA). Yet, no study has tested the interaction effects between NSSI and psychological symptoms on SA in community adolescent populations, or examined whether the interaction varies by gender. We sought to examine the interaction effects of NSSI and psychological symptoms on SA in adolescents and explore gender differences.

Methods

A school-based health survey in 3 provinces in China was conducted between 2013-2014. 14,820 students aged 10-20 years completed standard questionnaires, to record the details of various psychological symptoms, SA and NSSI.

Results

Psychological symptoms and NSSI were independently associated with a higher likelihood of SA in both boys and girls (p < 0.001). Adolescents with psychological, conduct or social adaptation symptoms without concurrent NSSI, were twice as likely to report SA (corresponding RORs were 1.80, 1.80 and 2.16, respectively; p < 0.01) than those who reported NSSI. Male adolescents with psychological, emotional, conduct or social adaptation symptoms had a higher risk of SA in the non-NSSI group than the NSSI group (corresponding RORs were 2.85, 2.26, 2.30 and 3.01 respectively; p < 0.01). While in girls, only adolescents with social adaptation symptoms had a higher risk of SA in the non-NSSI group than NSSI group (corresponding RORs was 1.71, p < 0.05). In the non-NSSI group, boys reporting psychological symptoms exhibited a higher likelihood of a SA than their female counterparts.

Conclusion

Psychological symptoms and NSSI are independently associated with an increased risk of SA in adolescents. However, to some extent, NSSI may reduce the risk of SA among individuals with psychological symptoms, especially in boys.

Childhood Maltreatment, Stressful Life Events, Cognitive Emotion Regulation Strategies, and Non-suicidal Self-Injury in Adolescents and Young Adults With First-Episode Depressive Disorder: Direct and Indirect Pathways

INTRODUCTION

Childhood maltreatment (CM), stressful life events (SLE), and cognitive emotion regulation strategies (CERS) have been considered crucial in the development of non-suicidal self-injury (NSSI) and major depressive disorder (MDD), but the pathways of this association are not clear. We aim to identify direct effects of CM and SLE on NSSI and depression severity and its indirect effects via CERS in adolescents and young adults with a diagnosis of MDD.

METHODS

A total of 114 patients (aged 14-24 years) with first episode MDD were included and further divided into the NSSI group (n = 56) and non-NSSI group (n = 58) according to the DSM-5 criteria. Diagnostic interviews and self-report measures were conducted to assess CM, SLE, CERS, and diagnose NSSI. Severity of depressive symptoms was measured using the Hamilton Rating Scale (HAMD). The structural equation model was used to assess the pathways.

RESULTS

MDD patients with NSSI had more frequent family history of mental illness, more experience of CM and SLE, more serious depression, less use of adaptive CERS, and more use of maladaptive CERS. In the final structural equation model (χ2 = 4.82, df = 6, p = 0.57, CFI = 1.0, TLI = 1.10, and RMSEA = 0), the experience of CM and SLE showed a significant indirect effect on NSSI through adaptive CERS. CM and SLE only had direct effects on depression severity.

CONCLUSIONS

NSSI are prevalent in adolescents and young adults with MDD and highly intertwined with CM, SLE, and CERS. Adaptive CERS, not maladaptive CERS may be a possible mechanism relating CM and SLE to NSSI in MDD patients.

Working with Young People at Risk of Suicidal Behaviour and Self-Harm: A Qualitative Study of Australian General Practitioners' Perspectives

General Practitioners (GPs) play a crucial role in the identification and support of young people at risk of suicidal behaviour and self-harm; however, no studies have explored GPs' perspectives, approaches, challenges, and resource needs when working with this cohort in an Australian setting. This was a qualitative study where fifteen GPs (Mage = 45.25 years) from multiple clinics in Western Australia took part in semi-structured interviews, and data were analysed thematically. Seven main themes were identified: (1) working with young people has its unique challenges; (2) screening and assessment tools can help to manage uncertainty and discomfort; (3) going beyond tools-the dialogue and relationship are most important; (4) there are limits to what we can offer in the time available; (5) the service access and referral pathways lack clarity and coordination; (6) the provision of mental health support should not fall on GPs alone; and (7) more comprehensive training in suicide and self-harm is needed. The findings highlight a number of opportunities to enhance care and better assist GPs working with young people who present with suicidal behaviour and self-harm, including considerations for conducting assessments, targeted resources such as training, and system and service improvements.

Depression, Non-Suicidal Self-Injury, and Suicidality in Adolescents: Common and Distinct Precursors, Correlates, and Outcomes

Depression, non-suicidal self-injury (NSSI), and suicidal thoughts and behaviors (STB) often emerge during adolescence. Despite considerable overlap in clinical presentation, risk factors, and implicated neurobiology, there is also evidence for divergence in terms of precursors, correlates, and outcomes. The complex interrelationships amongst these three clinical domains require considering both shared and divergent patterns of risk for depression, NSSI, and STB; a clearer understanding of these developmental trajectories will be needed to guide optimization and tailoring of early interventions.

Children and Adolescents' Psychological Well-Being Became Worse in Heavily Hit Chinese Provinces during the COVID-19 Epidemic

In light of the novel coronavirus's (COVID-19's) threat to public health worldwide, we sought to elucidate COVID-19's impacts on the mental health of children and adolescents in China. Through online self-report questionnaires, we aimed to discover the psychological effects of the pandemic and its associated risk factors for developing mental health symptoms in young people. We disseminated a mental health survey through online social media, WeChat, and QQ in the five Chinese provinces with the most confirmed cases of COVID-19 during the late stage of the country-wide lockdown. We used a self-made questionnaire that queried children and adolescents aged 6 to 18 on demographic information, psychological status, and other lifestyle and COVID-related variables. A total of 17,740 children and adolescents with valid survey data participated in the study. 10,022 (56.5%), 11,611 (65.5%), 10,697 (60.3%), 6868 (38.7%), and 6225 (35.1%) participants presented, respectively, more depressive, anxious, compulsive, inattentive, and sleep-related problems compared to before the outbreak of COVID-19. High school students reported a greater change in depression and anxiety than did middle school and primary school students. Despite the fact that very few children (0.1%) or their family members (0.1%) contracted the virus in this study, the psychological impact of the pandemic was clearly profound. Fathers' anxiety appeared to have the strongest influence on a children's psychological symptoms, explaining about 33% of variation in the child's overall symptoms. Other factors only explained less than 2% of the variance in symptoms once parents' anxiety was accounted for. The spread of COVID-19 significantly influenced the psychological state of children and adolescents in participants' view. It is clear that children and adolescents, particularly older adolescents, need mental health support during the pandemic. The risk factors we uncovered suggest that reducing fathers' anxiety is particularly critical to addressing young people's mental health disorders in this time.

Relationship between SIRT1 gene and adolescent depressive disorder with nonsuicidal self-injury behavior: Based on gene methylation and mRNA expression

OBJECTIVE

The incidence of non-suicidal self-injury (NSSI) behavior in adolescents is increasing year by year. Patients with a history of both depression and NSSI behavior tend to be at greater risk for suicide. At present, the mechanism of adolescent depressive disorder with NSSI behavior is not clear and still in research and exploration. The expression of the Silent Information Regulator 2 Related Enzyme 1 (SIRT1) gene is closely related to the level of serotonin in molecular mechanisms, and may be closely related to the occurrence and development of depressive disorder. This study aimed to explore the relationship between the SIRT1 gene and NSSI behaviors in adolescents with depressive disorder.

METHODS

A total of 15 adolescent depressed patients with NSSI behavior and 15 healthy controls were enrolled in the study. Bisulfite Sequencing PCR (BSP) was used to test the methylation level of SIRT1 gene promoter region of the participants. The real-time fluorescent quantitative PCR was conducted to measure the mRNA expression level of SIRT1 gene.

RESULTS

Our study found that the methylation level of SIRT1 gene promoter region at cytosine-guanine dinucleotide 5 (CpG5) site in depression group was higher than that of control group. Compared with that of control group, the plasma concentration of Sirt1 protein significantly decreased in depression group.

CONCLUSION

Our study investigated the methylation level and the mRNA expression of SIRT1 gene in adolescent depressive patients with NSSI behavior. The study points towards finding an in vivo molecular marker for those adolescent patients.

The Occurrence of Sexual Risk Behaviors and Its Association With Psychological Well-Being Among Kenyan Adolescents

Objective: Sexual risk behavior during adolescence is an important public health problem. Self-esteem and hopefulness are potentially important psychological factors that may play a role in the behavioral regulation mechanisms of adolescents. These factors are inadequately explored in sub-Saharan Africa. This study aimed at exploring patterns and associated factors for sexual risk behavior (SRB), self-esteem, and hopefulness among adolescents from a resource-poor setting in Kenya. Method: A cross-sectional study conducted in 2019 among 296 adolescents (12-17 years old) from rural Kilifi (n = 133) and urban informal settings of Nairobi (n = 163) in Kenya. Participants completed the Kilifi Health Risk Behavior Questionnaire, Rosenberg self-esteem questionnaire, and Hope scale administered via computerized tablets. A binary outcome variable based on the experience of adolescents of at least one of the five forms of SRB: transactional sex, sexual violence, intergenerational sex, early sexual debut, and condom non-use was generated. Bi-variate analysis was conducted to summarize various social-demographic and psychosocial factors. A multivariable logistic regression model was fitted to investigate factors associated with the occurrence of SRB, self-esteem, and hopefulness among adolescents. Results: About 13% of the participants had experienced a form of SRB, and among these, 36% reported co-occurrence of multiple forms of SRB. Adolescent SRB was largely characterized by having experienced sexual violence, as well as intergenerational and transactional sex. Higher scores of hopefulness were reported among adolescents who never experienced SRB (P = 0.03) at bivariate analysis level. However, both self-esteem and hopefulness were not significantly associated with the occurrence of SRB in the adjusted logistic regression analysis. Having depressive symptoms (Adj. OR = 3.8, 95% CI: 1.39-10.4), feeling unsafe in the neighborhood (Adj. OR = 3.4, 95% CI: 1.6-7.2), and being in higher compared with lower primary education level (Adj. OR = 0.3, 95% CI: 0.1-0.8) were statistically significantly associated with the occurrence of SRB. Conclusion: Targeted reproductive health interventions, designed with the cognizance of structural and social drivers of adolescent SRB, are needed to concurrently tackle multiple forms of SRB. It is important to integrate mental health promotion within these interventions. More research is needed to understand the mechanisms and implications of self-esteem and hopefulness for adolescent sexual and reproductive health.

Nonsuicidal self-injury in undergraduate students with major depressive disorder: The role of psychosocial factors

BACKGROUND

Nonsuicidal self-injury (NSSI) is related to childhood abuse, family relationships, interpersonal relationships, personality, but the interaction between them is still unclear, and how they interact in major depressive disorder (MDD).

METHODS

Collected data from 444 undergraduate degree students with MDD participated. Used the Eysenck Personality Questionnaire, Childhood Trauma Questionnaire, Interpersonal Relationship Comprehensive Diagnostic Scale, and Family Assessment Device to assess the patients' psychosocial factors. NSSI behavior was assessed through interviews. Use the Chi-square test, Wilcoxon rank-sum test, Kruskal-Wallis H-test, Distance Correlation, Structural Equation Mode for data analysis.

RESULTS

Overall, 34.2% of patients with MDD had a history of NSSI. MDD patients with a history of NSSI had significant differences in psychoticism, neuroticism, emotional abuse, physical abuse, sexual abuse, emotional neglect, troubles in conversation, ability to make friends and family roles. Among these factors, psychoticism was most related to NSSI, and child abuse, interpersonal relationships and family roles played a variety of roles in mediating the relationship with NSSI.

CONCLUSIONS

Psychosocial factors affect the occurrence of NSSI through chain intermediary effects.

Depression symptoms as a mediator between social support, non-suicidal self-injury, and suicidal ideation among Arab adolescents in Israel

The purpose of the current study was to explore whether depression symptoms mediate the relationships between perceptions of social support from three sources; namely parents, teachers, and peers, and non-suicidal self-injury (NSSI) and suicidal ideation. We also tested the interactions between the different sources of support. Focusing on the Arab-Israeli population is unique as it is an ethnic minority characterized with strong familial support, and less access to mental health services compared to the ethnic majority. Adolescents (N = 276; 65.6% girls; mean age 15.1 years) from the Arab minority in northern Israel were sampled (74% response rate). Participants were evaluated using validated scales assessing perceived social support, NSSI and suicidal ideation. Path analysis with Bayesian estimation supported the hypothesized model. Depression symptoms fully mediated the relationships between school-related social support (i.e., teachers and peers) and NSSI, and partially between parents’ support and suicidal ideation. Interactions between the social support sources were not significant, and cluster analysis indicated that each source is independently essential to understand NSSI and suicide ideation. This model emphasizes the importance of school-related factors in adolescents’ particular aspects of mental health, and suggests that one source of social support may not compensate for a lack of another.

Epigenetic Alterations of the Promoter Region of the POMC Gene in Adolescent Depressive Disorder Patients with Nonsuicidal Self-injury Behaviors

PURPOSE

The incidence of nonsuicidal self-injury (NSSI) behavior among adolescents increases year by year. Patients with a history of both depression and NSSI behaviors tend to have greater risk of suicide. At present, the mechanism of adolescent depressive disorder patients with NSSI behaviors is not clear, epigenetic mechanism may be involved. Proopiomelanocortin (POMC) gene may be associated with depressive disorder. The purpose of this study was to investigate DNA methylation of POMC gene promoter region of adolescent depressive disorder patients with NSSI behaviors.

METHODS

Bisulfite Sequencing PCR (BSP) was used to test the methylation level of POMC promoter of 15 adolescent depressive disorder patients with NSSI behaviors and 15 healthy controls (HC). Self-made questionnaires were used to collect clinical data of the case group and control group. Hamilton depression scale-24 (HAMD-24), Hamilton anxiety scale (HAMA), Symptom Checklist-90 (SCL-90) were used to evaluate the characteristics and severity of depressive, anxiety and psychotic symptoms. Adolescent self-injury questionnaire was used to assess NSSI behaviors and its severity.

RESULTS

BSP analysis found that the POMC methylation level of cytosine-guanine dinucleotide 1 (CpG1) site was higher in the case group than that of HC (P<0.05). The significance in POMC methylation at CpG1 between case group and HC was gender-independent, and CpG1 methylation level was higher in both male (P<0.05) and female (P<0.05) patients than that in HC. The CpG1 methylation level had a little correlation trends with family history of psychosis (P=0.05). We also found that POMC methylation level at CpG17 in female patients was significantly higher than that of the female HC (P<0.05).

CONCLUSION

There was abnormal methylation in the POMC promoter region of adolescent depressive disorder patients with NSSI behaviors, the methylation of CpG1 may act as epigenetic markers for those adolescents.

How should we respond to non-suicidal self-injury disclosures?: An examination of perceived reactions to disclosure, depression, and suicide risk

Identifying those who engage in non-suicidal self-injury (NSSI) rely heavily on self-disclosure. However, less than half of those who engage in NSSI disclose their self-injurious behavior often due to the fear of negative reaction. This study examined how perceived reactions to NSSI disclosure (i.e., 'negative reactions', 'tangible aid,' and 'emotional support') may be associated with suicide risk through depression. Participants were 385 undergraduate students who had a lifetime history of engaging in and disclosing at least one of their NSSI acts. Perceived reactions to NSSI disclosure were assessed through the Self-injury Social Reactions Questionnaire; suicide risk was assessed through the Suicidal Behavior Questionnaire Revised; depression was assessed through the Beck Depression Inventory-II. Path analyses were conducted to examine the indirect effects of perceived reactions to NSSI disclosure on suicide risk through depression. Exploratory analyses of independent models examining each reaction separately were conducted as well. In the full model, negative reactions and emotional support were indirectly associated with suicide risk through depression. In the independent models, all three reaction types were associated with suicide risk through depression. The current study elucidates a potential mechanism in which specific perceived reactions to NSSI disclosure may influence one's suicide risk.

Best practice when working with suicidal behaviour and self-harm in primary care: a qualitative exploration of young people's perspectives

OBJECTIVES

General practitioners (GPs) have a key role in supporting young people who present with suicidal behaviour/self-harm. However, little is known about young people's opinions and experiences related to GPs' practices for such presentations, and their decisions to disclose suicidal behaviour/self-harm to GPs. Additionally, existing guidelines for the management of suicide risk and/or self-harm have not incorporated young people's perspectives. This study aimed to explore young people's views and experiences related to the identification, assessment and care of suicidal behaviour and self-harm in primary care settings with GPs.

DESIGN, SETTING AND PARTICIPANTS

Two qualitative focus groups were conducted in Perth, Western Australia, with 10 young people in total (Mage = 20.67 years; range: 16-24). Data were collected using a semistructured, open-ended interview schedule and analysed using thematic analysis.

RESULTS

Five major themes were identified from the focus groups. (1) Young people wanted a collaborative dialogue with GPs, which included being asked about suicidal behaviour/self-harm, informed of treatment processes and having autonomy in decision making; (2) young people were concerned with a loss of privacy when disclosing suicidal behaviour/self-harm; (3) young people viewed labels and assessments as problematic and reductionist-disliking the terms 'risk' and 'risk assessment', and assessment approaches that are binary and non-holistic; (4) young people highlighted the importance of GPs' attitudes, with a genuine connection, attentiveness and a non-judgemental demeanour seen as paramount; and (5) young people wanted to be provided with practical support and resources, followed-up, and for GPs to be competent when working with suicidal behaviour/self-harm presentations.

CONCLUSIONS

Our study identified several concerns and recommendations young people have regarding the identification, assessment and care of suicidal behaviour/self-harm in primary care settings. Taken together, these findings may inform the development of resources for GPs, and support progress in youth-oriented best practice.

Understanding the Needs of Young People Who Engage in Self-Harm: A Qualitative Investigation

Self-harm is common and associated with adverse outcomes. Research about the risk factors for self-harm has informed the field with regard to clinical interventions that should be delivered for young people who engage in self-harm. Missing is an in-depth understanding of what the triggers of an urge to self-harm might be, including in young people being treated with a clinical intervention. Therefore, there is little knowledge about what techniques young people find helpful to deal with urges to self-harm when they occur. This qualitative study engaged seven young people with lived experience of self-harm in semi-structured interviews about the immediate triggers of the urge to self-harm, and helpful strategies to manage this urge. Thematic analysis using a general inductive approach revealed distressing emotions and a sense of isolation as key themes, with other triggers associated with their induction. Highlighted was the wide range of situations and emotions that can be triggering, such that a further key theme was the idiosyncratic nature of the self-help strategies young people found helpful. Interventions that are developed to support young people who self-harm must address this complexity and findings highlight the need for young people to maintain some autonomy and control while being supported to connect with others for support. This research adds to the literature on self-help strategies to support young people in moments when they are experiencing distressing emotions, feel isolated, and have an urge to self-harm providing important insight to the prevention and intervention for self-harm among young people.

A multi factorial model of self-harm behaviors in Anorexia-nervosa and Bulimia-nervosa

BACKGROUND

Co-existence of eating disorders and NSSI, suicide attempts and ideations is well established yet much is not known about the personality traits and behavioral tendencies that maintain this relationship. To this date no empirical work has been produced that offers a multifactorial view on the contributing variables to the occurrence of self-harm behaviors in EDs.

METHOD

Binge eating, depression, impulsivity, ruminations and loss aversion were assessed in a sample of 93 patients diagnosed with Anorexia-Nervosa and Bulimia-Nervosa and other EDs with a history of NSSI and suicide attempts.

RESULTS

Binge eating was found to be a predictor of depression, which in turn was found to be related to NSSI frequency, suicide attempts and suicide ideations. Ruminations were found to mediate a relationship between depression and suicide ideations. Trait impulsivity predicted suicide attempts, while the attentional construct of impulsivity was associated to suicide ideations as well as attempts. Higher loss aversion was positively associated with NSSI frequency and suicide ideations.

CONCLUSION

Our findings suggest that trait and state aspects of impulsivity are related to different self-harm behaviors in EDs. Exploring these differences is potentially of great value in understanding the process of transition from suicidal ideation to suicide attempt and the process of NSSI and may assist clinicians formulate better interventions for patients with EDs at risk. Ways in which individual findings in our model correspond with previous research and future implications are discussed.

A Protective Model for Suicidal Behaviors in American and Pakistani College Students

There is a paucity of cross-national studies evaluating protective models for suicidal behaviors. Thus, using a behavioral framework, the purpose of this study was to examine whether higher levels of life-enhancing behaviors could mitigate or weaken the relation between depressive symptoms and suicidal behaviors in United States and Pakistani college students. A total of 811 students (449 Pakistani and 362 U.S. students) participated in the study. Results indicated that the strength of the relation between depressive symptoms and suicidal behaviors was stronger for U.S. students. In addition, the association between depressive symptoms and suicidal behaviors weakened in the presence of high engagement in life-enhancing behaviors. This effect was comparable in strength for American versus Pakistani students. The results offer preliminary evidence for life-enhancing behaviors as a protective factor for suicide across unique cultural settings and may serve as a valuable area of focus for secondary prevention programs.

Predicting status along the continuum of suicidal thoughts and behavior among those with a history of nonsuicidal self-injury

Nonsuicidal self-injury (NSSI) and suicidal thoughts and behavior often co-occur, representing a growing public health concern. Despite extensive research examining suicidal thoughts and behavior among those who engage in NSSI, there is a lack of research investigating factors that, when considered together, can differentiate individuals along the continuum of suicidal thoughts and behavior (no history, suicidal ideation, suicide plan, suicide attempt). This study sought to address this question using a sample of 1178 college students with NSSI history (68.70% female). Discriminant function analysis was conducted including the following predictors: NSSI characteristics, negative affect difficulties, and behavioral and demographic risk factors for suicidal thoughts and behavior. Results suggest that self-disclosure of suicidal ideation, number of lifetime NSSI methods, NSSI frequency, depressive symptoms, and age most parsimoniously differentiate study groups. Those who use a greater number of NSSI methods and acts, paired with higher depressive symptoms and repeated self-disclosure of suicidal ideation are most likely to have a suicide attempt history; decreases in these variables suggest membership within less severe groups. Furthermore, older age may be related to greater suicidality. Findings suggest that the evaluation and co-occurrence of these variables may contribute to a more accurate suicide risk assessment.

Feasibility of a randomised controlled trial of remotely delivered problem-solving cognitive behaviour therapy versus usual care for young people with depression and repeat self-harm: lessons learnt (e-DASH)

BACKGROUND

Self-harm and depression are strong risk factors for repeat self-harm and suicide. We aimed to investigate the feasibility of a randomised controlled trial (RCT) of remotely delivered problem-solving cognitive behaviour therapy (PSCBT) plus treatment as usual (TAU) versus TAU in young people with repeat self-harm and depression.

METHODS

Single-blind multi-centre RCT with an internal pilot, pre-set stop-go criteria and qualitative semi-structured interviews. Eligible participants (aged 16-30 years) were recruited from 9 adult or child and adolescent self-harm and crisis services; had ≥ 2 lifetime self-harm episodes, one in the preceding 96 h; and Beck Depression Inventory-II (BDI-II) score ≥ 17. Participants were randomised (1:1) to either TAU or TAU and 10-12 sessions of PSCBT delivered by mobile phone or video-calling.

RESULTS

Twenty-two participants were recruited (11 in each arm), 10 (46%) completed follow-up at 6 months, 9 (82%) started the PSCBT and 4 (36%) completed it. The study did not meet three of its four stop-go criteria, reflecting considerable barriers to recruitment and retention. Participants had severe depression symptoms: with mean BDI-II 38.9 in the PSCBT and 37.2 in TAU groups, respectively. Three (14%) unblindings occurred for immediate safety concerns. Barriers to recruitment and retention included lack of agency for participants, severity of depression, recency of crisis with burden for participants and clinicians who diagnosed depression according to pervasiveness.

CONCLUSIONS

RCTs of PSCBT for young people with depression and self-harm are not feasible using recruitment through mental health services that conduct assessments following self-harm presentations. Clinician assessment following self-harm presentation mainly identifies those with severe rather than mild-moderate depression.

Disparities in Treatment of Older Adults with Suicide Risk in the Emergency Department

BACKGROUND/OBJECTIVE

We described characteristics and treatment received for older (≥60 years) vs younger (<60 years) adult emergency department (ED) patients with suicide risk.

DESIGN

Retrospective chart review.

SETTING

An ED with universal screening for suicide risk.

PARTICIPANTS

Eligible charts included a random sample of adults (≥18 years) who screened positive for suicidal ideation (SI) in past 2 weeks and/or a suicide attempt (SA) within the past 6 months. Visit dates were from May 2014 to September 2016.

RESULTS

A total of 800 charts were reviewed, with oversampling of older adults. Of the 200 older adults sampled, fewer older adults compared to younger adults (n = 600) had a chief complaint involving psychiatric behavior (53% vs 70%) or self-harm behavior (26% vs 36%). Although a higher number of older adults (93%) had documentation of current SI compared to younger adults (79%), fewer older adults (17%) reported SA in the past 2 weeks compared to younger adults (23%). Of those with a positive suicide screen who were discharged home, less than half of older adults received a mental health evaluation during their visit (42%, 95% CI 34-52) compared to 66% (95% CI 61-70) of younger adults who met the same criteria. Similarly, fewer older, than younger, adult patients with current SI/SA received referral resources (34%; 95% CI 26-43; vs 60%; 95% CI 55-65).

CONCLUSIONS

Significantly fewer suicidal older adult patients who were discharged home received a mental health evaluation when compared to similar younger adults. These findings highlight an important area for improvement in the treatment of older adults at risk for suicide.

Clinical Phenotype of Depression Affects Interleukin-6 Synthesis

Major depressive disorder (MDD) is not a single disease, but a number of various ailments that form one entity. Psychomotor retardation, anhedonia, sleep disorders, an increased suicide risk, and anxiety are the main symptoms that often define the clinical diagnosis of depression. Interleukin-6 (IL-6), as one of the proinflammatory cytokines, seems to be overexpressed during certain mental disorders, including MDD. Overexpression of IL-6 in depression is thought to be a factor associated with bad prognosis and worse disease course. IL-6 may directly affect brain functioning and production of neurotransmitters; moreover, its concentration is correlated with certain clinical symptoms within the wide range of depressive symptomatology. Furthermore, there is a strong correlation between IL-6 synthesis and psychosomatic functioning of the patient. This article discusses potential sources and significance of IL-6 in the pathogenesis of depression.
