Self-harm

The role of sleep quality and anxiety symptoms in the association between childhood trauma and self-harm attempt: A chain-mediated analysis in the UK Biobank

BACKGROUND

Childhood trauma is a risk factor for self-harm/suicidal behavior, but research on the potential association linking sleep quality and anxiety symptoms to childhood trauma and self-harm attempt is limited. The aim of this study was to describe the mediating role of sleep quality and anxiety symptoms between childhood trauma and self-harm attempt, and to provide a scientific basis for the prevention of self-harm behaviors.

METHODS

This study ultimately included 11,063 study participants who participated in the baseline survey of this large prospective cohort study of the UK Biobank. We used structural equation modeling (SEM) to analyze the chain mediating role of sleep quality and anxiety symptoms in childhood trauma and self-harm attempt while controlling for covariates.

RESULTS

A total of 19.58 % of study participants self-reported self-harm attempt. Sleep quality was negatively correlated with childhood trauma, anxiety symptoms, and self-harm attempt (p < 0.01). Childhood trauma, anxiety symptoms, and self-harm attempt were positively correlated (p < 0.01). In addition, after adjusting for confounders, anxiety symptoms were able to partially mediate the association between childhood trauma and self-harm attempt (effect value: 0.042, p < 0.01), and sleep quality and anxiety symptoms can chain mediate the association between childhood trauma and self-harm attempt (effect value:0.002, p < 0.01), with a total mediating effect of 65.67 % of the total effect. Subgroup analyses further showed that the mediating effects of sleep quality and anxiety symptoms on childhood trauma and self-harm attempt differed across age, gender, ethnicity, and smoking and drinking subgroups.

CONCLUSIONS

This study found a complex relationship between childhood trauma, sleep quality, anxiety symptoms, and self-harm attempt, with sleep quality and anxiety symptoms mediating the relationship between childhood trauma and self-harm attempt. Multiple avenues of intervention, such as the provision of professional psychological interventions and timely monitoring, should be used to improve the sleep quality and mental health of individuals with traumatic childhood experiences and to prevent the occurrence of emotionally harmful behaviors such as self-harm/suicide.

The Epidemiology of Genitourinary Self-inflicted Injuries: Analysis of the National Trauma Databank

OBJECTIVE

To provide insight into the epidemiologic characteristics and trends of genitourinary (GU) self-inflicted injury (SII).

METHODS

We used data from the National Trauma Databank between 2017 and 2020. We described the characteristics of GU SII cases based on injured organ and then compared male and female injuries.

RESULTS

We identified 56,463 patients with SII, of which 1508 (2.7%) had GU involvement. Most cases were male patients (77.3%) and white (70.6%). Median age was 35 years (IQR 26-50). The most commonly injured GU organs were kidney (43.4%), followed by scrotum/testes (22.5%), and penis (18.2%). Most cases (89.9%) represented a single-organ injury whereas 10.1% had 2 or more GU organs injured. Seventy-three of those with kidney injuries (11.2%) underwent nephrectomy. Only 1 patient performing GU SII had a diagnosis code for transsexualism but the majority (82.2%) suffered from pre-existing conditions of which 20.5% had 3 or more comorbidities. More than half the population (54.9%) had preexisting diagnosed mental or personality disorder. A non-GU co-injury was present in most cases (70.8%), most commonly affecting another abdominal organ (44.3%) or fractures (41.3%). A positive drug screen was found in 30.7% of cases. Most patients survived though 15.4% died. Ninety-four percentage of fatal cases had a concomitant non-GU injury.

CONCLUSION

GU injuries account for 2.6% of all SII. These patients are often young white males with known mental or personality disorders. Kidneys were the most common injured and mortality was highest in cases of kidney and bladder injuries with multi-organ trauma involving non-GU organs.

Pediatric suicide: Review of a preventable tragedy

Concepts of suicide are explored in this issue with a focus on suicide in children and adolescents. The epidemiology of pediatric suicide in the United States is reviewed; also, risk and protective factors, as well as prevention strategies, are discussed. Suicide in the pediatric athlete and the potential protective effect of exercise are examined. In addition, this analysis addresses the beneficial role of psychological management as well as current research on pharmacologic treatment and brain stimulation procedures as part of comprehensive pediatric suicide prevention. Though death by suicide in pediatric persons has been and remains a tragic phenomenon, there is much that clinicians, other healthcare professionals, and society itself can accomplish in the prevention of pediatric suicide as well as the management of suicidality in our children and adolescents.

Psychological Resilience Mediates the Association Between Childhood Maltreatment and Self-Harm Phenotype in Chinese Early Adolescents

Self-harm (SH) increases significantly in early adolescence with great variability, and childhood maltreatment (CM) contributes to this increase. Understanding the developmental pathway from CM to SH could provide clues for SH prevention. This study used latent class analysis (LCA) to detect the phenotype of SH and explored the role of psychological resilience in the pathway from the CM to SH phenotype among 5724 early adolescents (52.5% male). Three interpretable phenotypes of SH were identified: low SH (57.8%), medium SH (29.0%), and high SH (13.2%). Furthermore, CM was positively associated with the SH phenotype, psychological resilience mediated the association between CM and the SH phenotype (all ps < 0.001), and a larger mediating effect was observed in the medium SH (22.41%). Our findings offer new perspectives that improving psychological resilience can be used as an efficient intervention to reduce the risk of SH among early adolescents who have experienced CM.

The Relational Approach to Treating Self-Harm (RELATE): study protocol for a feasibility randomised controlled trial study of cognitive analytic therapy for adults who self-harm versus treatment at usual

BACKGROUND

Self-harm is a prevalent behaviour that has a major detrimental impact on a person's life. Psychological therapies have the potential to help, but evidence of effective interventions remains limited. Access and acceptability of interventions can also be a significant challenge, with individuals either being unable to access help or having to endure long waiting lists. Cognitive analytic therapy (CAT) is a time-limited and relationally-focused psychotherapy that may provide a valuable treatment option for people who self-harm. This protocol outlines the methodology for the first feasibility randomised controlled trial (RCT) of CAT for adults that self-harm. The trial will aim to determine the feasibility, acceptability and safety of undertaking larger-scale evaluations of CAT for self-harm within an RCT context.

METHOD

An RCT design with 1:1 allocation to CAT plus treatment as usual (TAU) or TAU alone. Participants will be adult outpatients with three or more instances of self-harm in the past year (target sample of n = 60). CAT will be 8 one-to-one weekly 60-min sessions plus a follow-up session up to 8 weeks after the last session. Assessments will occur at baseline, 12 weeks and 18 weeks after randomisation. Qualitative interviews with participants will gain insights into the feasibility and acceptability of CAT. Feasibility outcomes will be judged against progression criteria.

DISCUSSION

CAT may be an effective and accessible treatment option for people who self-harm, providing a more relationally orientated alternative to more behavioural therapies. The proposed feasibility RCT is an important first step in evaluating CAT as a treatment for self-harm.

TRIAL REGISTRATION

The trial was pre-registered (21/10/22) on ISR CTN (ISRCTN code: ISRCTN75661422).

Self-harm in burn patients: An analysis of Finnish patient records (2011-2020)

AIM

To collect data on self-harm burn patients at a national level in Finland and analyze patient characteristics.

MATERIAL AND METHODS

First, we went through The National Care Register for Health Care (Hilmo) records from 2011 to 2015 to find all patients in Finland with both burn and self-harm ICD10 codes. Then we investigated the medical records of all patients treated at the National Burn Centre (NBC) in Helsinki in the period 2011-2020. Patients admitted to the hospital because of self-harm burn injuries were compared to those without self-harm injuries. Patients below 18 years old were excluded.

RESULTS

The Hilmo register consisted of a total of 3391 adult burn patients admitted to any healthcare unit during the study period. Compared with non-self-harm patients, self-harm patients (N = 82) had lower mean age (41 years vs 54 years, p < 0.001) and longer hospitalization (18 days vs. 6 days, p < 0.05). Two-thirds of the self-harm patients (N = 38) admitted to the NBC in the period 2011-2020 had a pre-burn history of psychiatric care (66%) and one-third of them had a previous record of self-harm or suicide attempt. Men had more severe burns than women (mean TBSA 46% vs. 14%, p < 0.05), and seven of them died during the first 48 h of care, but this was not the case for any female patient.

CONCLUSIONS

Self-harm burn patients were younger and had longer hospitalization at all care levels than other burn patients. Based on medical records of hospitalized self-harm burn patients, we found clear gender differences in the severity of the burn injury and in mortality, with men suffering more severe injuries, in some cases leading to death. Recognizing high-risk patients pre-burn could have a strong preventive impact.

Identifying High-Risk Subgroups of College Students with Non-Suicidal Self-Injury: A Latent Profile Analysis and Two-Years Follow-up Study

Non-Suicidal Self-Injury (NSSI) is associated with a heightened overall risk of future psychopathological problems. However, elucidating specific characteristics that determine an increased risk for certain individuals remains an area requiring further exploration. This study aimed to identify latent subgroups in a sample of college students with NSSI. Additionally, it sought to explore the differential associations of these subgroups with their psychopathological status (e.g., borderline symptoms and suicidal tendencies) both at baseline and after two years. The sample comprised 259 participants (89% females, Mage = 20.39, SD = 1.90) who reported engaging in NSSI in the last year. Three latent groups were found. The group exhibiting severe NSSI-features, high emotion dysregulation, and low perceived social support was the profile with high-risk of psychopathology both at baseline and follow-up. The findings enhance our understanding of the complex association between NSSI and future mental health issues, aiding in the early identification of at-risk individuals.

Magnitude of self-harm and associated factors among postnatal mothers attending immunization clinics at public health facilities in Boneya Boshe Woreda, Western Ethiopia, 2023: institution-based cross-sectional study design

Background

Self-harm is a preventable, but a leading, cause of maternal morbidity and mortality all over the world, with a significant impact on healthcare systems.

Objective

To assess the magnitude of self-harm and associated factors among postnatal mothers attending immunization clinics.

Methods

An institution-based cross-sectional study was employed among postnatal mothers attending infant immunization clinics at public health facilities in Boneya Boshe Woreda, Western Ethiopia, 1 October to 30 October 2023. A pretested, face-to-face interviewer-administered structured questionnaire prepared by Kobo Toolbox was used to collect the data. Both bivariable and multivariable logistic regression analyses were done. The level of significance was declared at p-value <0.05 with a 95% CI.

Results

Among the 423 mothers enrolled in the study, 415 of them finally participated, at a response rate of 98.10%. The magnitude of self-harm was 12.53% (95% CI: 9.33, 15.73). Involvement of husband in maternity and child healthcare (AOR = 1.90; 95% CI: 1.12, 2.10), depression (AOR = 2.79; 95% CI: 2.14, 6.94), loneliness (AOR = 2.49; 95% CI: 1.15, 5.40), postpartum intimate partner violence (AOR = 2.15; 95% CI: 1.01, 4.54), average monthly income (AOR = 3.70; 95% CI: 2.17, 10.50), and postnatal care (AOR = 2.72; 95% CI: 1.28, 5.80) were significantly associated factors.

Conclusion and recommendations

The study sought a magnitude of self-harm that was slightly higher than the previous study conducted in the northern part of Ethiopia. Therefore, healthcare providers should focus on identified factors during postnatal care to overcome them. Similarly, the concerned body should develop an effective strategy based on the identified factors to pay attention to postnatal mothers.

Prediction of non-suicidal self-injury in adolescents at the family level using regression methods and machine learning

BACKGROUND

Adolescent non-suicidal self-injury (NSSI) is a major public health issue. Family factors are significantly associated with NSSI in adolescents, while studies on forecasting NSSI at the family level are still limited. In addition to regression methods, machine learning (ML) techniques have been recommended to improve the accuracy of family-level risk prediction for NSSI.

METHODS

Using a dataset of 7967 students and their primary caregivers from a cross-sectional study, logistic regression model and random forest model were used to test the forecasting accuracy of NSSI predictions at the family level. Cross-validation was used to assess model prediction performance, including the area under the receiver operator curve (AUC), precision, Brier score, accuracy, sensitivity, specificity, positive predictive value and negative predictive value.

RESULTS

The top three important family-related predictors within the random forest algorithm included family function (importance:42.66), family conflict (importance:42.18), and parental depression (importance:27.21). The most significant family-related risk predictors and protective predictors identified by the logistic regression model were family history of mental illness (OR:2.25) and help-seeking behaviors of mental distress from parents (OR:0.65), respectively. The AUCs of the two models, logistic regression and random forest, were 0.852 and 0.835, respectively.

LIMITATIONS

The key limitation is that this cross-sectional survey only enabled the authors to examine predictors that were considered to be proximal rather than distal.

CONCLUSIONS

These findings highlight the significance of family-related factors in forecasting NSSI in adolescents. Combining both conventional statistical methods and ML methods to improve risk assessment of NSSI at the family level deserves attention.

Analysis of Hospitals Switching From a "Danger to Self" Question to Universal Columbia-Suicide Severity Rating Scale Screening: Impact on Screenings, Identification of Suicide Risk, and Documented Psychiatric Care

Objective

Sutter Health launched system-wide general population standardized suicide screening with the Columbia-Suicide Severity Rating Scale (C-SSRS) screen (triage) version in 23 hospitals in 2019, replacing a one-question "danger to self" (DTS) assessment. This study analyzed the impact of C-SSRS implementation on screening rates, positive screenings, and documented psychiatric care within 90 days for all patients and a subgroup diagnosed with Major Depressive Disorder (MDD).

Methods

Adults seen at hospitals in the pre-period (July 1, 2017-June 30, 2019) and post-period (July 1, 2019-December 31, 2020) were identified using electronic health records. Outcomes were compared using chi-square statistics and interrupted time series (ITS) models.

Results

Pre-period, 92.8% (740,984/798,653) of patients were screened by DTS versus 84.6% (504,015/595,915) by C-SSRS in the post-period. Positive screening rates were 1.5% pre-period and 2.2% post-period, and 9.2% pre-period versus 10.8% post-period for those with MDD. Among individuals with positive screenings, 64.0% (pre-period) had documented follow-up psychiatric care versus 52.5% post-period and 66.4% of those with moderate or high-risk. Among all patients seen there was an overall increase in documentation of psychiatric care within 90 days (0.87% pre- to 0.96% post-period). ITS models revealed a 9.6% decline in screening, 1.3% increase in positive screenings, and 12.9% decline in documented psychiatric care following C-SSRS implementation (all p < 0.01).

Conclusions

Following implementation, there was meaningful increase in suicide risk identification, and an increase in the proportion of patients with documented psychiatric care. Observed relative declines in screening warrant future research examining opportunities and barriers to general population C-SSRS use.

Suicide and mortality following self-harm in Culturally and Linguistically Diverse communities in Victoria, Australia: insights from a data linkage study

Background

While cultural backgrounds are well-documented to be relevant to intentional self-harm, little is known about how cultural and linguistically diverse (CALD) backgrounds affect mortality outcomes following self-harm.

Aim

This study aimed to compare the risk of all-cause mortality and suicide after intentional hospital admissions for self-harm among people from CALD (vs. non-CALD) backgrounds.

Method

Linked hospital and mortality data in Victoria, Australia, was used to assess suicide and all-cause death after hospital admissions for self-harm among patients aged 15+ years. All-cause death was identified by following up on 42,122 self-harm patients (hospitalized between 01 July 2007 and 30 June 2019) until death or 15 February 2021. Suicide death was evaluated in 16,928 self-harm inpatients (01 January 2013 and 31 December 2017) until death or 28 March 2018. Cox regression models were fitted to compare mortality outcomes in self-harm patients from CALD vs. non-CALD backgrounds.

Outcomes

During the follow-up periods, 3,716 of 42,122 (8.8%) participants died by any cause (by 15 February 2021), and 304 of 16,928 (1.8%) people died by suicide (by 28 March 2018). Compared to the non-CALD group, CALD intentional self-harm inpatients had a 20% lower risk of all-cause mortality (HR: 0.8, 95% CI: 0.7-0.9) and a 30% lower risk of suicide (HR: 0.7, 95% CI: 049-0.97). Specifically, being from North Africa/Middle East and Asian backgrounds lowered the all-cause mortality risk; however, the suicide risk in Asians was as high as in non-CALD people.

Conclusion

Overall, people from CALD backgrounds exhibited lower risks of all-cause mortality and suicide following hospital admission for self-harm compared to the non-CALD group. However, when comparing risks based on regions of birth, significant variations were observed. These findings underscore the importance of implementing culturally tailored background-specific suicide preventive actions. The study focussed on outcomes following hospital admission for self-harm and did not capture outcomes for cases of self-harm that did not result in hospital admission. This limits generalisability, as some CALD people might avoid accessing healthcare after self-harm due to cultural factors. Future research that not limited to hospital data is suggested to build on the results.

Prevalence of suicide attempt, suicide ideation and self-harm at diagnosis in adolescents with eating disorders

BACKGROUND

Data concerning the suicide prevalence of eating disorder (ED) subtypes and predictive factors are lacking in youth. This study aimed to examine suicide attempts (SA), suicide ideation (SI) and self-harm (SH) upon diagnosis in adolescents with EDs.

METHODS

The prevalence of SA, SI and SH in ED subtypes was evaluated by retrospectively assessing the Home, Education/Employment, Eating, Activities, Drugs, Sexuality, Suicidal ideation and Safety (HEEADSSS) instrument of adolescents diagnosed with an ED. Clinical predictors of SI in anorexia nervosa (AN) and atypical AN (AAN) were assessed.

RESULTS

Among all participants (398), 41 (10.3%) reported SA, 126 (31.7%) SI and 60 (15.1%) SH. While SA did not differ statistically between ED subgroups (p = .123), they were two times more prevalent in the bulimia nervosa (BN) group (17.5%) than in the AN group (8.5%). In the BN group, SI was 2.3 times more prevalent than in the AN group (p = .001). The AN and ARFID groups exhibited substantially less SH (p = .036). Having a higher body mass index (BMI) was the only significant predictor of SI.

CONCLUSIONS

This study demonstrates that adolescents with EDs are at an increased risk for suicidality, highlighting the need for close screening, particularly in those with BN, AN-BP and AN with a higher BMI.

Ascertaining injury risk issues through big data analysis: text-mining based analysis of national emergency response data

Objectives

Injury prevention can be achieved through various interventions, but it faces challenges due to its comprehensive nature and susceptibility to external environmental factors, making it difficult to detect risk signals. Moreover, the reliance on standardized systems leads to the construction and statistical analysis of numerous injury surveillance data, resulting in significant temporal delays before being utilized in policy formulation. This study was conducted to quickly identify substantive injury risk problems by employing text mining analysis on national emergency response data, which have been underutilized so far.

Methods

With emerging issue and topic analyses, commonly used in science and technology, we detected problematic situations and signs by deriving injury keywords and analyzing time-series changes.

Results

In total, 65 injury keywords were identified, categorized into hazardous, noteworthy, and diffusion accidents. Semantic network analysis on hazardous accident terms refined the injury risk issues.

Conclusion

An increased risk of winter epidemic fractures due to extreme weather, self-harm due to depression (especially drug overdose and self-mutilation), and falls was observed in older adults. Thus, establishing effective injury prevention strategies through inter-ministerial and interagency cooperation is necessary.

Self-harm by single- and multi-agent medication poisoning in a retrospective analysis of a Poison Control Center database from January 2018 to December 2022

PURPOSE

Medication poisoning is the most common method of self-harm. Longitudinal studies incorporating pre- and post-COVID-19 pandemic data are required to describe the phenomenon and to evaluate the long-term impact on mental health.

METHODS

Calls to the Poison Control Center of Policlinico Umberto I Hospital - Sapienza University of Rome, Italy, were analyzed retrospectively for characteristics and clinical presentation of cases of interest from January 2018 to December 2022.

RESULTS

A total of 756 cases of self-harm by medication poisonings were recorded in the study period. A reduction in rate of cases in 2020 was followed by a return to pre-pandemic levels by 2021. When separately analyzing single- and multi-agent cases, occurrence of cases involving just one medication increased since early 2021, with a peak in 2022 (7.8% of total calls, 95% CI 6.2-9.5, from 4.9%, 95% CI 4.1-5.8 in 2018). This increase in the rate of cases, mostly of none or mild severity, was driven by youth aged 12-21, in which the relative proportion of single- versus multi-agent cases showed an increasing trend since 2020 (from 42.6% in 2018 to 78.6% in 2022). Acetaminophen was the medication most frequently involved and benzodiazepines the largest class. A psychiatric background was increasingly seen in 2022, especially in age group 12-21.

CONCLUSION

Single-agent medication self-harm may be an increasingly prevailing phenomenon. Young adolescents with a psychiatric background might be most vulnerable to this behavior in the COVID-19 pandemic aftermath. Healthcare professionals should expect favorable clinical outcome and improve both counseling and psychotherapy supervision in individuals at risk.

The Relationship between Ambivalence over Emotional Expression and Nonsuicidal Self-Injury Among Chinese Adolescents: A Longitudinal Moderated Mediation Model

BACKGROUND

Nonsuicidal self-injury (NSSI) has become a significant mental health concern for adolescents. Previous empirical studies have shown that ambivalence over emotional expression is positively associated with negative emotions and behaviors. However, little is known about the relationship between ambivalence over emotional expression and NSSI among adolescents. Therefore, this study used a longitudinal design to examine the relationship between ambivalence over emotional expression and NSSI among Chinese adolescents, and also to explore the mediating and moderating mechanisms underlying this relationship.

METHOD

A total of 1,672 students (45.8% males; Mage = 16.12 years, SD = 1.56) in a middle school in Guangzhou were tracked. The investigation was conducted twice, with an interval of 6 months.

RESULTS

Ambivalence over emotional expression was positively correlated with NSSI. After controlling for gender and baseline NSSI, anxiety symptoms fully mediated the association between ambivalence over emotional expression and NSSI. In addition, the relationship between ambivalence over emotional expression and NSSI was moderated by NSSI refusal self-efficacy.

CONCLUSIONS

These findings imply that to decrease ambivalence over emotional expression, to reduce anxiety symptoms, and to promote NSSI refusal self-efficacy may be useful for interventions and preventions of NSSI.HIGHLIGHTSTested the relationship between ambivalence over emotional expression and NSSI in adolescents.Examined a moderated-mediation model over six months.Found the mediated effect of anxiety symptoms and moderated effect of NSSI refusal self-efficacy in the relationship between ambivalence over emotional expression and NSSI.

Self-harming behaviors and forensic system-related factors: an analysis of the Ontario review board database

BACKGROUND

In Canada, ensuring public safety, and the safety and well-being of accused individuals under the jurisdiction of the provincial review board are very important. While previous studies have reported a significant risk of self-harming behaviors (non-suicidal self-injury and suicide attempt) in forensic psychiatric settings, no large population study has assessed any relationship between forensic system-related factors and self-harming behaviors. A better understanding of these factors can help clinicians implement protective measures to mitigate self-harming behaviors or actions.

METHODS

Using the Ontario Review Board (ORB) database covering 2014-2015 period (n = 1211, mean age = 42.5 ± 13.37 years, males = 86.1%), we analyzed the prevalence and factors associated with self-harming behaviors, emphasizing the characterization of the forensic system-related factors (ORB status, legal status, type of offense, previous criminal history, and victim relationship). The relationships between the forensic system-related factors and self-harming behaviors were explored using five separate logistic regression models, controlling for clinical and sociodemographic characteristics.

RESULTS

Approximately 4% of the individuals in the forensic system over the study period engaged in self-harming behaviors Among the studied patients, individuals determined to be unfit to stand trial and inpatients were significantly more likely to have self-harming behaviors. There was no significant relationship between the type of offence, victim relationship, and previous criminal history with self-harming behavior.

CONCLUSION

Forensic psychiatry inpatients should have close observation, screening, monitoring, and individual tailored management strategies for self-harming behaviors. The findings of this study indicate that forensic system-related factors, especially those that pertain to the status of individuals in the forensic system (i.e., unfit to stand trial and being an inpatient) are more responsible for self-harming behaviors among forensic patients in Ontario.

The influence of peer non-suicidal self-harm on young adults' urges to self-harm: experimental study

OBJECTIVE

To test the hypothesis that exposure to peer self-harm induces adolescents' urges to self-harm and that this is influenced by individual suggestibility.

METHODS

We recruited 97 UK-based adults aged 18-25 years with a recent history of self-harm, measuring baseline suggestibility (Resistance to Peer Influence; RPI) and perceived ability to control urges to self-harm (using an adapted item from the Self-Efficacy to Resist Suicidal Action scale; SEASA) before and after two self-harm vignettes featuring named peers from the participant's social network (to simulate exposure to peer non-suicidal self-harm) and after a wash-out exposure. We used paired t-tests to compare mean SEASA scores pre- and post-exposure, and linear regression to test for an association between RPI and change in SEASA scores pre- and post-exposure.

RESULTS

Perceived ability to control urges to self-harm was significantly reduced following exposure to peer self-harm (t(96) = 4.02, p < 0.001, mean difference = 0.61; 95% CI = 0.31, 0.91), but was not significantly different from baseline after exposure to a wash-out. We found no association between suggestibility and change in urges to self-harm after exposure to peer self-harm.

CONCLUSION

Our findings support social influences on self-harm in a sample of young adults, regardless of their individual degree of suggestibility.

Modeling and controlling the body in maladaptive ways: an active inference perspective on non-suicidal self-injury behaviors

A significant number of persons engage in paradoxical behaviors, such as extreme food restriction (up to starvation) and non-suicidal self-injuries, especially during periods of rapid changes, such as adolescence. Here, we contextualize these and related paradoxical behavior within an active inference view of brain functions, which assumes that the brain forms predictive models of bodily variables, emotional experiences, and the embodied self and continuously strives to reduce the uncertainty of such models. We propose that not only in conditions of excessive or prolonged uncertainty, such as in clinical conditions, but also during pivotal periods of developmental transition, paradoxical behaviors might emerge as maladaptive strategies to reduce uncertainty-by "acting on the body"- soliciting salient perceptual and interoceptive sensations, such as pain or excessive levels of hunger. Although such strategies are maladaptive and run against our basic homeostatic imperatives, they might be functional not only to provide some short-term reward (e.g. relief from emotional distress)-as previously proposed-but also to reduce uncertainty and possibly to restore a coherent model of one's bodily experience and the self, affording greater confidence in who we are and what course of actions we should pursue.

A smartphone-based intervention for young people who self-harm ('PRIMARY'): study protocol for a multicenter randomized controlled trial

BACKGROUND

Self-harm in young people is a public health concern connected with severe mental health problems, such as personality pathology. Currently, there are no specific evidence-based interventions available for young people who self-harm. Therefore, we developed PRe-Intervention Monitoring of Affect and Relationships in Youth (PRIMARY), a smartphone-based intervention, co-designed by clinicians and young people with lived experience of mental ill-health. PRIMARY combines the Experience Sampling Method (ESM) with weekly report sessions. The study aims to examine the effectiveness of PRIMARY with regard to reducing self-harm, and improving emotion regulation and quality of relationships.

METHODS

This study is a multicenter, parallel groups, randomized controlled trial (RCT) comparing the PRIMARY intervention to a waiting list control group. PRIMARY comprises 28 consecutive days of questionnaires five times each day (i.e., ESM) and four weekly report sessions. Participants will comprise 180 young people referred for treatment to the participating Dutch mental healthcare institutions and (1) are aged 12 to 25 years, and (2) engaged in ≥ 1 act of self-harm in the past year. Participants are randomly allocated to a study group after screening in a 1:1 ratio by an independent researcher using computer-generated randomization sequences with stratified block randomization by age (12 to 15 years / 16 to 25 years). Staff will conduct assessments with all participants at baseline (Wave 1), after 28 days (Wave 2), and in a subsample after 10 weeks of subsequent specialized treatment (Wave 3). The primary outcomes are self-harm, emotion regulation, and quality of relationships. Secondary outcomes include patient and clinician satisfaction. Exploratory analyses of ESM data will examine the relationship between emotions, social relationships, and self-harm.

DISCUSSION

The results of this trial will clarify whether an innovative smartphone-based intervention is effective for reducing self harm and improving emotion regulation and the quality of social relationships. It has the potential to fill a treatment gap of interventions specifically targeting self-harm. If proven effective, it would provide an accessible, easy-to-implement, low-cost intervention for young people. Furthermore, the ESM-data will allow detailed analyses into the processes underlying self-harm, which will contribute to theoretical knowledge regarding the behavior.

Experiences of Help from the Perspective of Parents Whose Adolescent Is Harming Themselves or Has Died by Suicide

Adolescent self-harm or suicide are emotionally difficult for parents, thus also parents need help. This qualitative descriptive study aimed to produce knowledge on the experiences of help received by Finnish parents (n = 23) whose adolescent is harming themselves or has died by suicide. The parents received diverse help for themselves, and for their self-harming adolescent or the deceased adolescent's sibling. Parents described negative experiences, but also factors that promoted their experience of help. There are many barriers to help related to the parents themselves, the adolescent, or to the social support system. Professional help should be easier to obtain and be based on the parents' individual expectations.

Self-Harm in Children and Adolescents Who Presented at Emergency Units During the COVID-19 Pandemic: An International Retrospective Cohort Study

OBJECTIVE

To compare psychiatric emergencies and self-harm at emergency departments (EDs) 1 year into the pandemic, to early pandemic and pre-pandemic, and to examine the changes in the characteristics of self-harm presentations.

METHOD

This retrospective cohort study expanded on the Pandemic-Related Emergency Psychiatric Presentations (PREP-kids) study. Routine record data in March to April of 2019, 2020, and 2021 from 62 EDs in 25 countries were included. ED presentations made by children and adolescents for any mental health reasons were analyzed.

RESULTS

Altogether, 8,174 psychiatric presentations were recorded (63.5% female; mean [SD] age, 14.3 [2.6] years), 3,742 of which were self-harm presentations. Rate of psychiatric ED presentations in March to April 2021 was twice as high as in March to April 2020 (incidence rate ratio [IRR], 1.93; 95% CI, 1.60-2.33), and 50% higher than in March to April 2019 (IRR, 1.51; 95% CI, 1.25-1.81). Rate of self-harm presentations doubled between March to April 2020 and March to April 2021 (IRR, 1.98; 95% CI, 1.68-2.34), and was overall 1.7 times higher than in March to April 2019 (IRR, 1.70; 95% CI, 1.44-2.00). Comparing self-harm characteristics in March to April 2021 with March to April 2019, self-harm contributed to a higher proportion of all psychiatric presentations (odds ratio [OR], 1.30; 95% CI, 1.05-1.62), whereas female representation in self-harm presentations doubled (OR, 1.98; 95% CI, 1.45-2.72) and follow-up appointments were offered 4 times as often (OR, 4.46; 95% CI, 2.32-8.58).

CONCLUSION

Increased pediatric ED visits for both self-harm and psychiatric reasons were observed, suggesting potential deterioration in child mental health. Self-harm in girls possibly increased and needs to be prioritized. Clinical services should continue using follow-up appointments to support discharge from EDs.

A qualitative study on lived experience of self-harm in South Asians in the UK: From reasons to recovery

OBJECTIVES

Self-harm rates and clinical presentations differ by ethnicity. South Asian women are at risk of self-harm. Previous research suggested investigating individuals' experiences with self-harm with qualitative studies in developing self-harm prevention strategies. This research aims to explore self-harm experiences among South Asians in the United Kingdom.

DESIGN

Qualitative study.

METHODS

Participants were recruited via third-sector organizations and online platforms. Semi-structured interviews were conducted with 11 South Asian individuals with a history of self-harm living in the United Kingdom. The data were analysed based on a reflective thematic analysis approach.

RESULTS

Results revealed four main themes: (1) reasons for self-harm; (2) recovery journey; (3) culture and mental health; and (4) the transition to suicidal thoughts and behaviours. Reasons for self-harm included negative life circumstances, social life difficulties, challenges faced during COVID-19 and mental health problems. Participants described their recovery journey by acknowledging the role of professional help, self-care, psychoeducation and personal growth, improving social relationships, and faith and spirituality. Cultural factors included generational differences and stigma. Culturally adapted psychological interventions were perceived as promising. The reported transition from self-harm to suicidal behaviours was linked to experiencing major stressful life events and the use of severe methods of self-harm.

CONCLUSIONS

The findings suggest that socio-cultural factors impact mental health and recovery processes among South Asians. Mental health services should consider improving culturally sensitive clinical practices in responding to self-harm among South Asian communities.

Self-harm in adolescence and risk of crash: a 13-year cohort study of novice drivers in New South Wales, Australia

INTRODUCTION

Self-harm and suicide are leading causes of morbidity and death for young people, worldwide. Previous research has identified self-harm is a risk factor for vehicle crashes, however, there is a lack of long-term crash data post licensing that investigates this relationship. We aimed to determine whether adolescent self-harm persists as crash risk factor in adulthood.

METHODS

We followed 20 806 newly licensed adolescent and young adult drivers in the DRIVE prospective cohort for 13 years to examine whether self-harm was a risk factor for vehicle crashes. The association between self-harm and crash was analysed using cumulative incidence curves investigating time to first crash and quantified using negative binominal regression models adjusted for driver demographics and conventional crash risk factors.

RESULTS

Adolescents who reported self-harm at baseline were at increased risk of crashes 13 years later than those reporting no self-harm (relative risk (RR) 1.29: 95% CI 1.14 to 1.47). This risk remained after controlling for driver experience, demographic characteristics and known risk factors for crashes, including alcohol use and risk taking behaviour (RR 1.23: 95% CI 1.08 to 1.39). Sensation seeking had an additive effect on the association between self-harm and single-vehicle crashes (relative excess risk due to interaction 0.87: 95% CI 0.07 to 1.67), but not for other types of crashes.

DISCUSSION

Our findings add to the growing body of evidence that self-harm during adolescence predicts a range of poorer health outcomes, including motor vehicle crash risks that warrant further investigation and consideration in road safety interventions. Complex interventions addressing self-harm in adolescence, as well as road safety and substance use, are critical for preventing health harming behaviours across the life course.

Work incapacity and psychiatric patient care following attempted suicide - a cohort study of 65 097 Swedish twins

BACKGROUND

Research is scarce on the role of familial factors and previous psychiatric care on the association between suicide attempt and future work incapacity as well as deterioration in mental health. We aimed to investigate the associations between suicide attempt and sickness absence, disability pension and psychiatric patient care and to study the influence of previous psychiatric care and familial factors (genetics and shared environment) on the associations.

METHODS

The study included 65 097 twins living in Sweden on 31st of December 2006, aged 19-60 years. The twins were followed 2007-2013 regarding sickness absence, disability pension, inpatient care or specialized outpatient care for a mental diagnosis. Cox regression models were performed for the whole sample, and conditional models for discordant twin pairs. The analyses were also stratified by psychiatric care before 2007.

RESULTS

We found that suicide attempt predicted sickness absence, disability pension, and future mental diagnosis among the whole sample. The discordant twin pair analyses showed that the association between suicide attempt and sickness absence or disability pension was influenced by familial factors. Stratified analyses of individuals with or without psychiatric care before 2007 showed that previous psychiatric care had some impact on the associations.

CONCLUSIONS

A suicide attempt is a risk factor for work incapacity and psychiatric patient care. Familial factors and previous psychiatric care play a role in the associations between attempting suicide and work incapacity as well as psychiatric patient care. These factors are important when developing measures preventing work incapacity among those with a suicide attempt.

Is the association between sexual minority status and suicide-related behaviours modified by rurality? A discrete-time survival analysis using longitudinal health administrative data

BACKGROUND

While self-reported data shows that lesbian, gay, and bisexual (LBG) individuals have a greater suicide-related behaviours (SRB) risk, little is known about how rurality may amplify SRB risk associated with sexual minority status. Sexual minority individuals in rural areas may experience unique stressors due to stigma and a lack of LGB-specific social and mental health services. Using a population-representative sample linked to clinical SRB outcomes, we examined whether rurality modifies the association between sexual minority status and SRB risk.

METHODS

A nationally representative survey linked to administrative health data was used to construct a cohort of individuals (unweighted n = 169,091; weighted n = 8,778,115) in Ontario, Canada, and captured all SRB-related emergency department visits, hospitalizations, and deaths between 2007 and 2017. Sex-stratified discrete-time survival analyses were used to examine interactions between rurality and sexual minority status on SRB risk while controlling for potential confounders.

RESULTS

Sexual minority men had 2.18 times higher SRB odds compared to their heterosexual counterparts (95%CI 1.21-3.91), while sexual minority women had 2.07 times higher odds (95%CI 1.48-2.89) after adjusting for the confounders. The Rurality Index of Ontario and the Index of Remoteness were associated with the odds of SRB in a dose-response manner. No significant interactions were observed between rural and sexual minority status.

CONCLUSIONS

Our study provides evidence that rural and sexual minority status both independently contribute to an elevated likelihood of SRB; however, rurality did not appear to modify SRB risk by sexual orientation. Implementation and evaluation of interventions to reduce SRB in both rural and sexual minority populations are required.

Factitious dermatitis in children and adolescents is highly comorbid with psychiatric disorders

OBJECTIVE

Factitious dermatitis (FD) is a psychocutaneous disorder characterized by self-induced skin lesions. FD is related to mental illness, but the correlation is poorly defined in the pediatric population. Our study aims to investigate the risk of psychiatric disorders diagnosed after the FD diagnosis in children and adolescents.

METHODS

We conducted a retrospective cohort study over a seven-year period (2016-2022) to measure the incidence and risk ratio of psychiatric disorders in patients under age 19 years. The FD cohort was defined as patients with FD (International Classification of Diseases, ICD-10-CM: L98.1); the control cohort was defined as patients who attended a regular dermatology visit by applying a diagnostic code of disease of the skin and subcutaneous tissue (ICD-10-CM: L00-99).

RESULTS

A total of 453 patients were identified for analysis. We found that FD patients were more likely to be diagnosed with anxiety disorder (Relative risk [RR] 7.63; P < 0.001), obsessive-compulsive disorder (RR 6.20; P < 0.001), attention-deficit hyperactivity disorder (RR 4.90, P < 0.001), depression (RR 2.27; p = 0.02), sleep disorder (RR 2.23; P = 0.01), impulse disorder (RR 2.20; P = 0.04), and conduct disorder (RR 2.14; P = 0.04) within 1 year following the diagnosis of FD.

CONCLUSION

FD is highly comorbid with psychiatric disorders. Though some practitioners believe FD could result from experimental or recreational behavior in children and adolescents, possible underlying psychiatric disorders should never be overlooked.

Affective temperaments mediate aggressive dimensions in bipolar disorders: A cluster analysis from a large, cross-sectional, international study

BACKGROUND

Affective temperaments show potential for aggressive behavior (AB) preventive strategies in bipolar disorder (BD). We aim to define intra-diagnostic subgroups of patients with BD based on homogeneous behaviors related to AB. Subsequently, to assess whether affective temperament dimensions may contribute to the presence and severity of AB.

METHODS

Patients with BD were recruited. AB was evaluated through the modified overt aggression scale (MOAS); affective temperaments were assessed with the TEMPS-A. A cluster analysis was conducted based on TEMPS-A and MOAS scores. Stepwise backward logistic regression models were used to identify the predictive factors of cluster membership.

RESULTS

799 patients with BD were enrolled. Three clusters were determined: non-aggressive (55.5 %), self-aggressive (18 %), and hetero-aggressive (26.5 %). Depressive, irritable, and anxious temperament scores significantly increased from the non-aggressive (lower) to the self-aggressive (intermediate) and the hetero-aggressive group (highest). A positive history of a suicide attempt (B = 5.131; OR = 169.2, 95 % CI 75.9; 377) and rapid cycling (B = -0.97; OR = 0.40, 95 % CI 0.17; 0.95) predicted self-aggressive cluster membership. Atypical antipsychotics (B = 1.19; OR = 3.28, 95 % CI 2.13; 5.06) or SNRI treatment (B = 1.09; OR = 3, 95 % CI 1.57; 5.71), psychotic symptoms (B = 0.73; OR = 2.09, 95 % CI 1.34; 3.26), and history of a suicide attempt (B = -1.56; OR = 0.20, 95 % CI 0.11; 0.38) predicted hetero-aggressive cluster membership.

LIMITATIONS

Recall bias might have affected the recollection of AB.

CONCLUSIONS

Clinical factors orientate the prevention of different ABs in BD. Affective temperaments might play a role in preventing AB since patients with more pronounced affective temperaments might have an increased risk of showing AB, in particular hetero-AB.

Digital self-harm and suicidality among adolescents

BACKGROUND

Research on digital self-harm - the anonymous online posting, sending, or otherwise sharing of hurtful content about oneself - is still in its infancy. Yet unexplored is whether digital self-harm is related to suicidal ideation or suicide attempts.

METHODS

In the current study, survey data were collected in 2019 from a national sample of 4972 American middle and high school students (M_age  = 14.5; 50% female). Logistic regression analysis was used to assess whether lifetime engagement in two different indicators of digital self-harm was associated with suicidal thoughts and attempts within the past year.

RESULTS

Logistic regression analysis showed that engagement in digital self-harm was associated with a five- to sevenfold increase in the likelihood of reporting suicidal thoughts and a nine- to 15-fold increase in the likelihood of a suicide attempt.

CONCLUSIONS

Results suggest a connection between digital self-harm and suicidality. As such, health professionals must screen for digital self-harm to address underlying mental health problems among youth that may occur prior to or alongside suicidality, and parents/caregivers must convey to children that they are available to dialog, support, and assist with the root issues that may eventually manifest as digital self-harm.

"Treat Them Like a Human Being…They are Somebody's Somebody": Providers' Perspectives on Treating Patients in the Emergency Department After Self-Injurious Behavior

To understand ED providers' perspective on how to best care for individuals who present to US emergency departments (EDs) following self-injurious behavior, purposive recruitment identified nursing directors, medical directors, and social workers (n = 34) for telephone interviews from 17 EDs. Responses and probes to "What is the single most important thing ED providers and staff can do for patients who present to the ED after self-harm?" were analyzed using directed content analysis approach. Qualitative analyses identified four themes: treat patients with respect and compassion; listen carefully and be willing to ask sensitive personal questions; provide appropriate care during mental health crises; connect patients with mental health care. Participants emphasized treating patients who present to the ED after self-injurious behavior with respect and empathy. Hospitals could incentivize provider mental health training, initiatives promoting patient-provider collaboration, and reimbursement strategies ensuring adequate staffing of providers with time to listen carefully.

Resilience to Self-Harm

Background: Although a wide range of studies discuss prevalence and risk factors associated with self-harm, protective factors that are equally important are rarely explored. Moreover, much of our understanding of young individuals who engage in self-harm come from studies conducted in Western countries with very little emphasis on marginalized groups. Aim: This scoping review identifies research on resilience among marginalized youth and youth living in low- and middle-income countries (LMICs) who show evidence of self-harm. Method: A scoping review following Arksey and O'Malley's (2005) framework was conducted. This effort included drawing upon peer-reviewed research published between January 2000 and September 2020 to identify protective factors and coping strategies that are employed by individuals 10-29 years old with self-harming tendencies. Results: A total of 15 original papers met the inclusion criteria. The majority of the LMIC publications were from China. Social support, positive youth development, and religiosity were the most frequently reported protective factors. Conclusion: Despite widespread concern about self-harm, there are few peer-reviewed articles that look at resilience or recovery among youth in LMICs and among marginalized young people. In addition to various internal and external protective factors, this scoping review identifies gaps in our understanding of resilience to self-harm among youth belonging to these groups.

Individual and dyadic network analyses of depressive symptoms in Chinese postpartum couples: A cross-sectional study

BACKGROUND

The network approach to psychopathology is symptom oriented and may open new possibilities for intervention development and health care practices in postpartum depression.

OBJECTIVE

To investigate the individual and dyadic symptom network of postpartum depression in Chinese mothers and fathers in the very early postpartum period.

DESIGN

A cross-sectional study was conducted.

SETTINGS AND PARTICIPANTS

A total of 457 couples in the 2∼3 days postpartum period was recruited consecutively from a hospital in Guangzhou, China from September 2020 to April 2021.

METHODS

The Edinburgh Postnatal Depression Scale and socio-demographic and obstetric data sheet were used to collect data. We estimated the individual symptom networks of postpartum mothers and fathers separately and a dyadic symptom network that consisted of symptoms of both spouses. Network characteristics including global strength and node centralities were analyzed and systematically compared.

RESULTS

Strength centralities in the individual networks showed acceptable stability [Correlation stability coefficient (CS) for mothers = 0.60; CS for fathers = 0.52]. The central depressive symptoms in mothers were Crying (Z_strength = 1.32), Overwhelmed (Z_strength = 1.01) and Sad mood (Z_strength = 0.93). The central depressive symptom in fathers was Sad Mood (Z_strength = 1.35). The symptom "Crying" had a distinctive link to thoughts of self-harm in fathers. The symptom network of mothers (global strength = 4.15) was more interconnected than that of fathers (global strength = 3.74). There was a statistically significant but unstable within-couple connection of thoughts of self-harm (CS = 0.21).

CONCLUSIONS

Postpartum mothers are more vulnerable to activation spreads of depressive symptoms than postpartum fathers. Symptoms including "Sad mood", "Overwhelmed" and "Crying" warrant the attention of health care providers. Investigations with larger sample sizes and gender-sensitive instruments are needed to further unfold the individual and dyadic symptom dynamics of postpartum depression.

Intentional self-harm in culturally and linguistically diverse communities: A study of hospital admissions in Victoria, Australia

PURPOSE

To examine the rates and profiles of intentional self-harm hospital admissions among people from culturally and linguistically diverse and non-culturally and linguistically diverse backgrounds.

METHODS

A retrospective analysis of 29,213 hospital admissions for self-harm among people aged 15 years or older in Victoria, Australia, was conducted using data from the Victorian Admitted Episodes Dataset between 2014/2015 and 2018/2019. The Victorian Admitted Episodes Dataset records all hospital admissions in public and private hospitals in Victoria (population 6.5 million). Population-based incidence of self-harm, logistic regression and percentages (95% confidence intervals) were calculated to compare between culturally and linguistically diverse groups by birthplaces and the non-culturally and linguistically diverse groups of self-harm admissions.

RESULTS

When grouped together culturally and linguistically diverse individuals had lower rates of (hospital-treated) self-harm compared with the non-culturally and linguistically diverse individuals. However, some culturally and linguistically diverse groups such as those originating from Sudan and Iran had higher rates than non-culturally and linguistically diverse groups. Among self-harm hospitalised patients, those in the culturally and linguistically diverse group (vs non-culturally and linguistically diverse group) were more likely to be older, Metropolitan Victorian residents, from the lowest socioeconomic status, and being ever or currently married. Self-harm admissions by persons born in Southern and Eastern Europe were the oldest of all groups; in all other groups number of admissions tended to decrease as age increased whereas in this group the number of admissions increased as age increased.

CONCLUSION

There was considerable heterogeneity in rates of hospital-treated self-harm in culturally and linguistically diverse communities, with some countries of origin (e.g. Sudan, Iran) having significantly higher rates. Some of this variation may be due to factors relating to the mode of entry into Australia (refugee vs planned migration), and future research needs to examine this possibility and others, to better plan for support needs in the culturally and linguistically diverse communities most affected by self-harm. Combining all culturally and linguistically diverse people into one group may obscure important differences in self-harm. Different self-harm prevention strategies are likely to be needed for different culturally and linguistically diverse populations.

The relationship between negative life events and non-suicidal self-injury (NSSI) among Chinese junior high school students: the mediating role of emotions

BACKGROUND

Adolescent non-suicidal self-injury (NSSI) is common and adolescence is the most common period of first self-injury, and the occurrence of NSSI is influenced by negative life events and emotional symptoms. The mediating role of emotional symptoms in the interaction between negative life events and NSSI has not been carefully investigated yet.

METHODS

For middle school students in three schools in a Chinese province, the Adolescents Self-Harm Scale was used to investigate NSSI, the Adolescent Self-Rating Life Events Check List was used to investigate adolescent negative life events, and the Self-Rating Anxiety Scale and Self-Rating Depression Scale were used to assess their emotional symptoms. After the description of general data and the test for differences between groups, the relationship between negative life events, emotional symptoms and NSSI was analyzed using Pearson correlation analysis. Structural equation modeling was used to analyze the mediating role of emotions in negative life events and NSSI.

RESULTS

A total of 2376 junior high school students completed this survey, which revealed an annual NSSI prevalence of 37.1% (n = 881) and a higher prevalence of NSSI among girls and rural adolescents. Among adolescents who developed NSSI, 67.4% (N = 594) used multiple means of self-injury. The most common means of self-injury was hair pulling (51.0%), and the most common NSSI purpose and external factors/events were venting bad emotions or feelings (57.5%) and poor academic performance (44.9%), respectively. Negative life events, emotional symptoms and NSSI were positively associated (P < 0.05). Structural equation modeling with negative life events, emotional symptoms and NSSI as variables showed that the model-fit index matched the data well, with RMSEA = 0.073, AGFI = 0.945, GFI = 0.980, CFI = 0.985, NFI = 0.982, TLI = 0.968, IFI = 0.985, and negative life events, emotional symptoms (anxiety, depression) and NSSI all had direct effects with standardized path coefficients of 0.16, 0.19, and 0.23, respectively, with negative life events playing an indirect role in NSSI through emotional symptoms and emotional symptoms playing an incomplete mediating role in negative life events and NSSI.

CONCLUSION

The prevalence of NSSI was higher among Chinese junior high school students. Both negative life events and emotional symptoms were direct risk factors for NSSI. In addition, negative life events were also indirect risk factors for NSSI, and emotional symptoms played an incomplete mediating role in the relationship between the effects of negative life events and NSSI. This indicates that the combination of reducing the frequency of negative life events while maintaining individual emotional stability during adolescent development can effectively reduce the prevalence of NSSI in adolescents.

Hierarchical topological model of the factors influencing adolescents' non-suicidal self-injury behavior based on the DEMATEL-TAISM method

This study analyzed the factors influencing adolescents' non-suicidal self-injury (NSSI) behavior and their interrelationships, and established a total influencing factor model. Through a literature analysis and semi-structured interviews with 87 adolescents and 27 experts in Guangxi Province, China, 13 influencing factors were identified from six aspects: physiological factors, cognitive factors, emotional factors, social support factors, social environment, and NSSI behavior. A system of factors influencing adolescents' NSSI behavior and a model of the factors influencing the comprehensive antagonism multilevel explanatory structure were obtained using a combination of Decision-Making Trial and Evaluation Laboratory technique and Total Adversarial Interpretive Structural Model. In descending order, NSSI, emotional state, self-efficacy, and self-cognition influenced adolescents' NSSI behavior. Social environment, exercise, and recreation had a greater impact on other factors, while NSSI, emotional regulation ability, and emotional state were greatly affected by other factors. Emotion regulation ability, self-cognition, self-efficacy, family support, school support, social support, and sleep were found to be the core factors influencing NSSI behavior of adolescents. These factors could be used to directly intervene in adolescent NSSI behavior. Timely treatment of adolescents' negative emotional states is directly conducive to preventing NSSI behavior and alleviating its severity.

Persons Who Engage in Self-Harm While in the Emergency Department: A Case-Control Analysis

ABSTRACT

Some patients engage in self-harm behaviors while in the emergency department. Risk factors for self-harm have been described for inpatient and outpatient/community settings, but not among emergency department patients. Authors conducted case-control, retrospective reviews of medical records and incident reports for emergency department patients in two academic medical centers. Variables were analyzed using conditional logistic regression. There were 113 individuals who engaged in self-harm while in the emergency department and 226 individuals who did not. Four variables were significant in the final model: a history of nonsuicidal self-harm (odds ratio [OR], 4.28; 95% confidence interval [CI], 1.95-9.41), opioid use in the prior 2 weeks (OR, 2.89; CI, 1.19-7.02), current manic episode (OR, 3.59; CI, 1.33-9.70), and a history of seizures (OR, 4.19; CI, 1.16-15.14). Risk of self-harm while in the emergency department may be mitigated with interventions that support adaptive coping skills, promptly address pain and withdrawal symptoms, and treat mania.

Antidepressant use and risk of self-harm among people aged 40 years or older: A population-based cohort and self-controlled case series study

BACKGROUND

Studies on the association between antidepressants and self-harm in adults were mostly conducted over a decade ago and have inconsistent findings. We aimed to compare self-harm risks by antidepressant classes among people aged 40 years or older with depression.

METHODS

Individuals aged ≥40 years with depression who initiated antidepressant treatment between 2001 and 2015 were retrieved from the Hong Kong Clinical Data Analysis & Reporting system, and were followed up until December 31, 2016. We conducted self-controlled case series (SCCS) analyses to estimate the incidence rate ratio (IRR) of self-harm comparing the pre-exposure (90 days before the first antidepressant use), index exposure (the first antidepressant use), and subsequent exposure (subsequent antidepressant use) periods to nonexposed periods. We applied Cox proportional hazard regressions to estimate the hazard ratio (HR) of self-harm comparing five antidepressant classes (tricyclic and related antidepressant drugs [TCAs], selective serotonin reuptake inhibitors [SSRIs], noradrenergic and specific serotonergic antidepressants [NaSSAs], serotonin-norepinephrine reuptake inhibitors [SNRIs], and others).

FINDINGS

A total of 48,724 individuals were identified. SCCS analyses (N = 3,846) found that the increased self-harm risk occurred during the pre-exposure (IRR: 22.24; 95% CI, 20.25-24.42), index exposure (7.03; 6.34-7.80), and subsequent exposure periods (2.47; 2.18-2.79) compared to the unexposed period. Cohort analyses (N = 48,724) found an association of higher self-harm risks in short-term (one year) for NaSSAs vs. TCAs (HR, 2.13; 95% CI, 1.53-2.96), SNRIs vs. TCAs (1.64; 1.01-2.68), and NaSSAs vs. SSRIs (1.75; 1.29-2.36) in the 40-64 years group. The higher risk remained significant in long-term (> one year) for NaSSAs vs. TCAs (1.55; 1.26-1.91) and NaSSAs vs. SSRIs (1.53; 1.26-1.87). In the 65+ group, only short-term differences were observed (SSRIs vs. TCAs [1.31; 1.03-1.66], SNRIs vs. SSRIs [0.44; 0.22-0.87], and SNRIs vs. NaSSAs [0.43; 0.21-0.87]).

INTERPRETATION

Within-person comparisons did not suggest that antidepressant exposure is causally associated with an increased risk of self-harm in people with depression. Between-person comparisons revealed differences in self-harm risks between certain pairs of antidepressant classes. These findings may inform clinicians' benefit-risk assessments when prescribing antidepressants.

Risk of self-harm in post TIA patients: A population-based cohort study

OBJECTIVE

The purpose of this study was to determine whether individuals who have experienced a transient ischemic attack (TIA) have an increased risk of self-harm behaviors.

METHODS

In this matched cohort study, we reviewed the electronic health records of all patients admitted for any reason to Hong Kong public hospitals between January 1, 1993, and December 31, 2019. We selected a post-TIA cohort consisting of 37,356 patients and a comparison cohort comprising 37,352 subjects. All participants enrolled in this study were followed up until a diagnosis of self-harm, death from other causes, or the end of 2020, whichever occurred first. Univariate Cox proportional hazards regression models were used to calculate the risk of self-harm since the onset of TIA.

RESULTS

Throughout the 27-year study period, the number of individuals exhibiting self-harm behavior in the TIA and comparison groups was 1031 (2.76%) and 512 (1.37%), respectively. The TIA group had a higher proportion of subjects with self-harm (χ² = 178, p < .001). The incidence rates of self-harm were 33.94 and 19.27 per 10,000 person-years in TIA patients and comparators, respectively. Compared with the comparators, the adjusted hazard ratio for self-harm in TIA patients was 1.63 (95% confidence interval, 1.46-1.82).

CONCLUSIONS

TIA is associated with an increased risk of self-harm. Healthcare professionals should help identify patients at heightened risk and provide efficient and targeted prevention strategies for this population.

Risk of self-harm or suicide associated with specific drug use disorders, 2004-2016: a population-based cohort study

BACKGROUND AND AIMS

Drug use disorders are associated with increased risk of self-harm. Risk differences associated with specific types of drug use disorders are yet to be comprehensively reported. This study aimed to examine the risk of self-harm or suicide associated with different drug use disorders in Hong Kong.

DESIGN

Population-based cohort study.

SETTING

The Clinical Data Analysis and Reporting System (CDARS) managed by the Hong Kong Hospital Authority.

PARTICIPANTS

Cases were people ages 10 years or older who visited a hospital Accident and Emergency department between 1 January, 2004 and 31 December, 2016 with any of 10 specific drug use disorders (comprising opioid; ketamine; methamphetamine; sedative, hypnotic, or anxiolytic; amphetamine or related stimulant; cocaine; cannabis; hallucinogen; unspecified or other drug; and polydrug). Each case was matched with two controls, selected from a subset of people in CDARS sharing the same gender, age and psychiatric profile. A total of 8270 cases and 16 540 matched controls were included.

MEASUREMENTS

Incidence and adjusted hazard ratio (aHR) of subsequent self-harm or suicide for each specific drug use disorder were estimated.

FINDINGS

The most prevalent drug use disorder was opioid use disorder (2523; 30.51%) and the least prevalent was hallucinogen use disorder (77; 0.93%). The crude incidence of self-harm or suicide ranged from 26.57 (95% CI, 14.23-44.55) per 1000 person-years for cannabis use disorder to 91.97 (77.32-108.37) for polydrug use disorder. The highest risk of self-harm or suicide was observed in ketamine (aHR, 16.36; 95% CI, 11.03-24.29) and opioid (15.97; 10.73-23.23) use disorders.

CONCLUSIONS

In Hong Kong, all types of drug use disorders appear to be significantly associated with increased risk of self-harm or suicide, but risk levels vary by type of drug use disorder.

Suicide and self-harm in low- and middle- income countries during the COVID-19 pandemic: A systematic review

There is widespread concern over the potential impact of the COVID-19 pandemic on suicide and self-harm globally, particularly in low- and middle-income countries (LMIC) where the burden of these behaviours is greatest. We synthesised the evidence from the published literature on the impact of the pandemic on suicide and self-harm in LMIC. This review is nested within a living systematic review (PROSPERO ID CRD42020183326) that continuously identifies published evidence (all languages) through a comprehensive automated search of multiple databases (PubMed; Scopus; medRxiv, PsyArXiv; SocArXiv; bioRxiv; the WHO COVID-19 database; and the COVID-19 Open Research Dataset by Semantic Scholar (up to 11/2020), including data from Microsoft Academic, Elsevier, arXiv and PubMed Central.) All articles identified by the 4th August 2021 were screened. Papers reporting on data from a LMIC and presenting evidence on the impact of the pandemic on suicide or self-harm were included. Methodological quality was assessed using an appropriate tool, and a narrative synthesis presented. A total of 22 studies from LMIC were identified representing data from 12 countries. There was an absence of data from Africa, the Pacific, and the Caribbean. The reviewed studies mostly report on the early months of COVID-19 and were generally methodologically poor. Few studies directly assessed the impact of the pandemic. The most robust evidence, from time-series studies, indicate either a reduction or no change in suicide and self-harm behaviour. As LMIC continue to experience repeated waves of the virus and increased associated mortality, against a backdrop of vaccine inaccessibility and limited welfare support, continued efforts are needed to track the indirect impact of the pandemic on suicide and self-harm in these countries.

Suicide and non-suicide mortality and associated risk factors among suicide attempters: A 10-year follow-up of a large cohort in rural China

Previous suicide attempt is a strong risk factor for subsequent suicide and other causes of mortality, but evidence from China is sparse. In this study, follow up face-to-face interviews were conducted with suicide attempters or a key informant, and any subsequent deaths were examined through local cause-of-death censoring databases to ascertain details surrounding the death. Competitive risk models and Cox proportional hazard regression models were used to ascertain significant risk factors of suicide, non-suicide and overall deaths following suicide attempt. Predictive nomograms were also constructed to predict the probability of suicide, non-suicide, and overall deaths. A total of 1103 suicide attempters were successfully interviewed with an average follow-up time of 7.48 (7.38-7.57) years. The cumulative rates of suicide at 1, 2, 3, 5 and 10 years were 0.27%, 0.63%, 0.91%, 1.56%, and 1.83%, respectively. Factors significantly associated with subsequent suicide were advancing age, history of suicide attempt, and mental disorders. Significant risk factors for non-suicide death included males, advancing age, and physical illness. Overall deaths during the follow-up period were associated with males, advancing age, physical illness, and mental disorders. Predictive models showed good ability with satisfactory C-indexes (between 0.77 and 0.86) and excellent calibration performance in predicting the varying causes of subsequent death among suicide attempters in rural China.

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.

Self-harm and Aggression in Chinese Early Adolescents: Their Co-occurrence and the Role of Bullying Victimization

Self-harm and aggression increase markedly during early adolescence. However, few studies considered these harmful behaviors simultaneously. This study employed a person-centered approach to identify profiles of adolescents who differed in their patterns of self-harm, reactive aggression, and proactive aggression, examined the stability of these patterns, and explored the effect of bullying victimization on latent profile membership and transition. A total of 2463 early adolescents (48.8% girls, M_age = 13.93 ± 0.59) participated in two waves of the study over six months. The results indicated that low symptoms profile (80.4%), moderate aggression profile (14.2%), high aggression profile (3.0%), and high self-harm profile (2.4%) were identified at time 1, and low symptoms profile (82.1%), dual-harm profile (7.6%), high aggression profile (7.7%), and high self-harm profile (2.6%) were identified at time 2. Adolescents assigned to at-risk profiles showed moderate to high transition, suggesting the developmental heterogeneity of self-harm and aggression. Moreover, adolescents high in bullying victimization were more likely to belong or transition to at-risk profiles. The findings revealed the co-occurring and transitional nature of self-harm and aggression and the transdiagnostic role of bullying victimization, which can be used to guide prevention and intervention strategies.

Sleep duration, depressive symptoms, and digital self-harm among adolescents

BACKGROUND

This study examines the relationship between sleep duration, depression, and engagement in a novel cyber behavior, digital self-harm, among adolescents.

METHOD

Logistic regression analyses were conducted using cross-sectional data from the 2019 Florida Youth Substance Abuse Survey (N = 9,819; 48% male; avg. grade level = 9th grade [SD = 1.9]) to analyze the association between sleep duration and digital self-harm. A Karlson-Holm-Breen (KHB) analysis was used to assess whether depressive symptoms attenuate this association.

RESULTS

Bivariate results indicated that longer sleep duration was associated with lower incidence of digital self-harm. Multivariate results showed that sleep duration was inversely associated with engaging in digital self-harm, net of all covariates. Depressive symptoms attenuated the influence of sleep duration on digital self-harm by 50.72%.

CONCLUSIONS

Both insufficient sleep and depressive symptoms were associated with engagement in digital self-harm among adolescents. Prospective research is needed, however, to confirm this pathway. Practitioners and clinicians should consider discussing digital self-harm with adolescents and parents, especially if adolescents are experiencing poor sleep and depressive symptoms.

Does Nonsuicidal Self-Injury Predict Later Suicidal Attempts? A Review of Studies

Co-occurrence of nonsuicidal self-injury (NSSI) and suicide attempts (SA) might occur because they share common risk factors, or alternatively because one leads to the other. Using search terms salient to NSSI and SA, we screened 555 studies to identify 17 that presented temporal data about NSSI and SA. Much of the evidence indicates that NSSI predates SA, especially among females and individuals with depressive symptoms, or diagnosed with borderline personality disorder or mood disorders. However, in some studies, associated risk factors likely accounted for the effect. Greater NSSI frequency to a threshold increases risk for later SA. Findings suggest that the behaviors have common predisposing factors, but that there is also a potent gateway effect whereby NSSI precedes SA.

Association of Patient-Reported Outcomes With Subsequent Nonfatal Self-injury After a New Cancer Diagnosis

Importance

Nonfatal self-injury (NFSI) is a patient-centered manifestation of severe distress occurring in 3 out of 1000 patients after cancer diagnosis. How to identify patients at risk for NFSI remains unknown.

Objective

To examine the associations between patient-reported outcome measures and subsequent NFSI in patients with cancer.

Design, Setting, and Participants

This population-based matched case-control study included adults with a new cancer diagnosis reporting an Edmonton Symptom Assessment System (ESAS) score within 36 months of diagnosis in Ontario, Canada, 2007 to 2019. Data analysis was performed January 2007 to December 2019.

Main Outcomes and Measures

Cases included patients with NFSI, and controls were patients without NFSI. Cases and controls were matched 1:4. Multivariable conditional logistic regression assessed the association between moderate to severe ESAS symptom scores and total ESAS (t-ESAS, range 0-90) score with NFSI in the subsequent 180 days.

Results

Of 408 858 patients reporting 1 or more ESAS assessments, 425 patients experienced NFSI and reported an ESAS score in the preceding 180 days. Of those, 406 cases were matched to 1624 control patients without an NFSI. Cases reported a higher proportion of moderate to severe symptoms and higher t-ESAS score than controls prior to the event. After adjustment, moderate to severe anxiety (odds ratio [OR], 1.61; 95% CI, 1.14-2.27), depression (OR, 1.66; 95% CI, 1.20-2.31), and shortness of breath (OR, 1.65; 95% CI, 1.18-2.31) and each 10-point increase in t-ESAS score (OR, 1.51; 95% CI, 1.40-1.63) were independently associated with higher odds of subsequent NFSI.

Conclusions and Relevance

In this case-control study, reporting moderate to severe anxiety, depression, and shortness of breath and an increasing t-ESAS score after cancer diagnosis were associated with higher odds of NFSI in the following 180 days. These data support the prospective use of routine ESAS screening as a means of identifying patients at higher risk for NFSI to improve supportive care.

The association between non-suicidal self-injury and negative life events in children and adolescents in underdeveloped regions of south-western China

Background

The association between negative life events and Non-suicidal self-injury (NSSI) in children and adolescents has been extensively discussed. Nevertheless, little is known about the relationship between negative life events and repetition and severity of NSSI. This survey aims to understand the association between NSSI prevalence, severity, repetition and the negative life events in children and adolescents in underdeveloped regions in south-western China.

Methods

In this population-based cross-sectional study, 3,146 children and adolescents were included from underdeveloped regions of south-western China, and each of them requested to complete a self-assessment questionnaire. The Modified Version of Adolescents Self-Harm Scale (MASHS) and the Adolescent Self-rating negative Life Events Check-list were used to evaluate NSSI behaviors and negative life events, respectively. The statistical implementation of this study was carried out in the R statistical software, and the logistic regression analysis method was used to analyze the relationship between negative life events and adolescents' non-suicidal self-injury behaviors.

Results

The average age of all included participants was 13.31 years old. The lifetime prevalence of NSSI was 47.0% (95% CI [36.3-58.0%]). Gender, grade level and ASLEC was positively associated with NSSI. Further analysis revealed that, for all five dimensions of ASLEC, only interpersonal relationship factor (IRF) (OR 1.77 (95% CI [1.06-2.97])), health adaptation factor (HAF) (OR 2.08 (95% CI [1.31-3.31])) showed prominent association with NSSI. Multivariate Logistic regression models revealed that, repetitive NSSI (OR 4.54 (95% CI [3.66-5.63])) and NSSI severity (OR 9.01 (95% CI [6.11-13.29])) were positively associated with ASLEC.

Conclusion

NSSI is very common among children and adolescents in underdeveloped regions of south-western China. Negative life event are positively associated with NSSI, repeated NSSI, and severe NSSI. Negative life events centered intervention measures might be effective in reducing NSSI among school children and adolescents in underdeveloped regions of south-western China.

Exploring the suicidal continuum: Deliberate self-harm diversity and severity as predictors of suicidal ideation and suicide attempts

Deliberate self-harm (DSH) in adolescence is a predictor of suicidal thoughts and behaviors (STBs). However, there is still a lack of research systematizing the association between DSH and STBs. Therefore, our main goal was to analyze if DSH diversity and severity predicted suicidal ideation and suicide attempts. Our sample comprised 237 Portuguese adolescents and young adults with a history of DSH, from community (80.2%, n = 190) and clinical (19.8%, n = 47) settings, aged between 14 and 23 years (M = 17.31, SD=1.36). Results showed that DSH diversity and severity were significant predictors of suicidal ideation and suicide attempts. These results were further discussed, underlining the impact that DSH has for suicide risk and highlighting the need to address further variables to understand these suicidality trajectories.

Effectiveness of Nonsuicidal Self-Injury Interventions among Incarcerated Women in Correctional Facilities and Secure Settings: An Integrative Review

Nonsuicidal self-injury (NSSI) is prevalent among incarcerated women in correctional facilities. This poses a challenge in selecting appropriate intervention. This integrative review aimed to identify effective interventions for managing NSSI among incarcerated women. Whittemore and Knafl's framework for integrative reviews was used, and eight databases were searched with 11 papers meeting the inclusion criteria. Six interventions for NSSI for incarcerated women were identified as promising in reducing the rate of NSSI. Data did not support the effectiveness of gender-specific interventions for incarcerated women. There is a need for further research to identify appropriate interventions to target NSSI among incarcerated women.

Childhood Separation From Parents and Self-Harm in Adolescence: A Cross-Sectional Study in Mainland China

As the prevalence of self-harm among adolescents in Chinese escalates, finding out the potential risk factors associated with self-harm behaviors has aroused much attention. This study aims to explore the association between parent-child separation and series of self-harm (SH) subtypes among Chinese adolescents. We survey a total of 4,928 middle school students aged from 12 to 18 years at school. Parent-child separation was investigated from four dimensions-occurrence of parental separation, separation status, age at first separation and duration of separation. Self-harm series are deemed as five subtypes-highly lethal self-harm, less lethal self-harm with visible tissue damage, self-harm without visible tissue damage, self-harmful behaviors with latent damage and psychological self-harm. Multivariate logistic regression is used to explore the associations between parent-child separation and different subtypes of self-harm among adolescents. Paternal separation is associated with each type of self-harm whilst maternal separation is not correlated with highly lethal self-harm. Except for highly lethal self-harm, the other four subtypes of self-harm demonstrate a relation with both length of paternal separation and maternal separation with aOR ranging from 1.02 to 1.06. Individuals who suffer parental separation prior to the age of three were at a higher risk for four types of less-lethal self-harm. The association of parent-child separation with self-harm deserves our attention, and future research is needed to identify the underlying mechanisms.
