Contagion of deliberate self-harm among adolescent inpatients

Gender dysphoria in adolescence: examining the rapid-onset hypothesis

The sharp rise in the number of predominantly natal female adolescents experiencing gender dysphoria and seeking treatment in specialized clinics has sparked a contentious and polarized debate among both the scientific community and the public sphere. Few explanations have been offered for these recent developments. One proposal that has generated considerable attention is the notion of "rapid-onset" gender dysphoria, which is assumed to apply to a subset of adolescents and young adults. First introduced by Lisa Littman in a 2018 study of parental reports, it describes a subset of youth, primarily natal females, with no childhood indicators of gender dysphoria but with a sudden emergence of gender dysphoria symptoms during puberty or after its completion. For them, identifying as transgender is assumed to serve as a maladaptive coping mechanism for underlying mental health issues and is linked to social influences from peer groups and through social media. The purpose of this article is to analyze this theory and its associated hypotheses against the existing evidence base and to discuss its potential implications for future research and the advancement of treatment paradigms.

A service-user digital intervention to collect real-time safety information on acute, adult mental health wards: the WardSonar mixed-methods study

Background

Acute inpatient mental health services report high levels of safety incidents. The application of patient safety theory has been sparse, particularly concerning interventions that proactively seek patient perspectives.

Objective(s)

Develop and evaluate a theoretically based, digital monitoring tool to collect real-time information from patients on acute adult mental health wards about their perceptions of ward safety.

Design

Theory-informed mixed-methods study. A prototype digital monitoring tool was developed from a co-design approach, implemented in hospital settings, and subjected to qualitative and quantitative evaluation.

Setting and methods

Phase 1: scoping review of the literature on patient involvement in safety interventions in acute mental health care; evidence scan of digital technology in mental health contexts; qualitative interviews with mental health patients and staff about perspectives on ward safety. This, alongside stakeholder engagement with advisory groups, service users and health professionals, informed the development processes. Most data collection was virtual. Phase 1 resulted in the technical development of a theoretically based digital monitoring tool that collected patient feedback for proactive safety monitoring. Phase 2: implementation of the tool in six adult acute mental health wards across two UK NHS trusts; evaluation via focused ethnography and qualitative interviews. Statistical analysis of WardSonar data and routine ward data involving construction of an hour-by-hour data set per ward, permitting detailed analysis of the use of the WardSonar tool.

Participants

A total of 8 patients and 13 mental health professionals participated in Phase 1 interviews; 33 staff and 34 patients participated in Phase 2 interviews.

Interventions

Patients could use a web application (the WardSonar tool) to record real-time perceptions of ward safety. Staff could access aggregated, anonymous data to inform timely interventions.

Results

Coronavirus disease 2019 restrictions greatly impacted the study. Stakeholder engagement permeated the project. Phase 1 delivered a theory-based, collaboratively designed digital tool for proactive patient safety monitoring. Phase 2 showed that the tool was user friendly and broadly acceptable to patients and staff. The aggregated safety data were infrequently used by staff. Feasibility depended on engaged staff and embedding use of the tool in ward routines. There is strong evidence that an incident leads to increased probability of further incidents within the next 4 hours. This puts a measure on the extent to which social/behavioural contagion persists. There is weak evidence to suggest that an incident leads to a greater use of the WardSonar tool in the following hour, but none to suggest that ward atmosphere predicts future incidents. Therefore, how often patients use the tool seems to send a stronger signal about potential incidents than patients' real-time reports about ward atmosphere.

Limitations

Implementation was limited to two NHS trusts. Coronavirus disease 2019 impacted design processes including stakeholder engagement; implementation; and evaluation of the monitoring tool in routine clinical practice. Higher uptake could enhance validity of the results.

Conclusions

WardSonar has the potential to provide a valuable route for patients to communicate safety concerns. The WardSonar monitoring tool has a strong patient perspective and uses proactive real-time safety monitoring rather than traditional retrospective data review.

Future work

The WardSonar tool can be refined and tested further in a post Coronavirus disease 2019 context.

Implementation of Brief Admission by Self-Referral in Child and Adolescent Psychiatry in Sweden: Insights from Implementers and Staff

Brief admission by self-referral, which allows patients to briefly admit themselves to a psychiatric ward, is a crisis intervention designed to reduce suicide and self-harm. This method was introduced in Sweden for adult patients in 2015, achieving high patient satisfaction and good acceptance among staff. In 2018, the method was adapted and implemented in pediatric psychiatry. The present study comprehensively describes the multifaceted strategies for implementing brief admissions, including planning, education, financing, restructuring, quality management, and policy implementation and reform. It also includes staff's opinions of the practice of brief admissions for young people. Neither of these topics has been addressed in the existing literature. During the study period (April 2018-April 2021), 63 brief admission contracts were established. The number of new contracts increased exponentially (12.7%) per quarter (p < 0.05), and staff satisfaction with both the implementation and its benefits for unstable patients was high. Brief admission by self-referral can be successfully implemented in pediatric psychiatry and appears to be a functional crisis management method for adolescents.

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.

Introducing brief admissions by self-referral in child and adolescent psychiatry: an observational cohort study in Sweden

BACKGROUND

Brief admission by self-referral, a novel crisis intervention designed to reduce suicide and self-harm in adults, was adopted for adolescents in paediatric psychiatry in Malmö, Sweden, in 2018. We aimed to investigate changes in utilisation of emergency psychiatric care.

METHODS

We did an observational longitudinal cohort study in The University Hospital in Malmö, Sweden, which provides the only psychiatric emergency unit with 24 h psychiatric facilities in Region Skåne. Eligible patients were those aged 13-17 years who were admitted to the psychiatric facility, who had at least one emergency visit or admission during the 6 months before admission, and had prominent features of instability and self-harm, corresponding to at least three of the nine criteria for borderline personality disorder as per the DSM-5 as assessed by a paediatric psychiatrist during the admission. Patients with intellectual disabilities, psychosis, or language barriers were excluded. Patients who signed a brief admissions contract between April 1, 2018, and April 30, 2021, were eligible for inclusion in the study. A brief admissions contract allows patients to admit themselves to psychiatric emergency care for a transitory time. The primary outcome measures were the number of emergency visits, emergency admissions, inpatient days, and episodes of coercive (involuntary) care, compared at individual level before and after signing the brief admissions contract until end of follow-up. The number of visits and days were modelled using random-effects Poisson regression models, and the relative changes in the expected numbers of days per time unit were reported as rate ratios (RRs).

FINDINGS

Of the 928 patients admitted to the psychiatric facility between April 1, 2018, and April 30, 2021, 60 were excluded, and a further 801 did not meet the inclusion criteria for age, previous emergency visits, or having at least three of the nine criteria of borderline personality disorder. 67 patients were eligible for inclusion, but four patients did not sign a contract. 63 patients were included in the study, including 60 females (95%) and three (5%) males, with a mean age of 14·8 years (SD 1·7). Ethnicity data were not collected. Patients were followed up for a median of 13·5 months (IQR 9·2 -19·6). After signing the contract, there was a decrease in the number of emergency visits (RR 0·22 [95% CI 0·15-0·32]; p<0·0001), emergency admissions (RR 0·26 [0·19-0·35]; p<0·0001), inpatient days (RR 0·29 [0·26-0·32]; p<0·0001), and inpatient days including brief admissions (RR 0·44 [95% CI 0·40-0·48]; p<0·0001). Episodes of coercive care did not change significantly (RR 0·99 [95% CI 0·40-2·43]; p=0·98). Psychiatric evaluation due to persistent suicidal ideations immediately after discharge was required for five patients.

INTERPRETATION

Our findings suggest that brief admissions can be successfully implemented in paediatric psychiatry and appear to be an effective crisis management method for adolescents, associated with reduced demand for emergency care. Future randomised controlled trials are warranted.

Patients with borderline personality disorder and the effects of compulsory admissions on self-harm behaviour: a questionnaire study

BACKGROUND

Previous research on patients with borderline personality disorder (BPD) has indicated negative effects, including increased suicidality, from long hospital admissions and paternalism. Still, long-term compulsory admissions have been reported to occur regularly. Less is known about how healthcare personnel perceives these admissions and to what extent they think the use of compulsory care can be diminished. This study addresses those questions to make care more beneficial.

METHODS

A questionnaire study, the respondents being nurses and psychiatric aides employed at psychiatric hospital wards in Sweden. The questionnaire contained questions with fixed answers and room for comments. 422 questionnaires were distributed to 21 wards across Sweden, and the response rate was 66%. The data were analysed with descriptive statistics and qualitative descriptive content analysis.

RESULTS

Most respondents experienced that more than a week's compulsory admission either increased (68%) or had no effect (26%) on self-harm behaviour. A majority (69%) considered the compulsory admissions to be too long at their wards, with detrimental effects on the patients. They also recognized several reasons for compulsory admissions without medical indication, like doctors' fear of complaints and patients' lack of housing. Also, patients sometimes demand compulsory care. Respondents recommended goal-oriented care planning, around three-day-long voluntary admissions, and better outpatient care to reduce compulsory hospital admissions.

DISCUSSION

These findings imply that many BPD patients are regularly forced to receive psychiatric care that inadvertently can make them self-harm more. The respondents' comments can be used as a source when formulating clinical guidelines.

Acquired Constriction Band Syndrome Affecting Multiple Digits – A Case Report

Rubber band syndrome is a condition that usually affects children because of wearing a rubber band on the wrist or the ankle. Depending on the degree of pressure caused by the band, patients may present acutely with ischemia and necrosis of the tissues distal to the bands or chronically with change in shape, oedema, loss of function, sensation and rarely amputation. This condition is very rare in adults and most reports in literature are in patients with cognitive impairment or psychiatric illness. We report 62-year-old lady with a background of a psychiatric illness who presented with an acquired constriction band syndrome affecting multiple digits of both hands.

Level of Evidence: Level V (Therapeutic)

Hospital staff at most psychiatric clinics in Stockholm experience that patients who self-harm have too long hospital stays, with ensuing detrimental effects

BACKGROUND

Previous research on patients who self-harm has indicated potential negative effects from long hospital stays. Yet, such care has been reported to occur regularly. We conducted this questionnaire study to investigate how hospital staff, who treat self-harming patients, experience the relation between lengths of stay and self-harm behaviour, and the motives for non-beneficial hospital stays.

METHODS

The respondents of the questionnaire were nurses and mental health workers employed at public inpatient wards in Stockholm, treating patients who self-harm. The questionnaire contained questions with fixed answers and room for comments. A total of 304 questionnaires were distributed to 13 wards at five clinics, and the response rate was 63%. The data were analysed with descriptive statistics and qualitative descriptive content analysis.

RESULTS

The results show that most staff experienced that more than a week's stay either increased (57%) or had no effect (33%) on self-harm behaviour. Most respondents at most clinics considered the stays to be too long at their wards, and that the stays could be reduced. The respondents recognized several reasons for non-beneficial hospital stays, like fear of suicidal behaviour and doctors' fear of complaints. Patients appearing as demanding or fragile were thought to be given more care than others. The respondents' comments confirmed the majority's experience of detrimental effects from longer hospital stays.

CONCLUSIONS

A majority of the health care staff experienced that patients who self-harm often receive too long hospital stays, with detrimental effects, and they had experienced several non-medical reasons for such care.

I Just Pulled Myself Together and Realised I had to be Responsible: Adolescents' Experiences of Having a Friend Who Self-Harms

Background

Self-harm usually begins during adolescence and adolescents that self-harm most commonly confide in friends, yet to date, there is little research from the friend's perspective.

Objective

This qualitative study explores adolescents' experiences of what it is like to have a friend who self-harms by cutting and what this experience means for friendship, the wider peer group and psychological well-being.

Methods

Semi-structured interviews were conducted face-to-face with a community sample of eight females aged between 13 and 18 years, living in England. Interpretative Phenomenological Analysis was used to analyse the data.

Results

Four superordinate themes emerged: desperately searching for meaning, I will be there at all costs, too hot to handle and identification. Adolescents were concerned about escalations in their friends' behaviours and felt a sense of duty to help, but the majority experienced a dilemma as to whether to disclose to others and all reported some form of distress.

Conclusions

The results highlight the important, yet complex nature of friendship in this context. Friends play a key role in supporting adolescents who self-harm but need greater support managing this role and the effects. Schools/colleges should educate young people about self-harm to increase their knowledge and skills in relation to supporting a friend with this issue. Furthermore, they should promote environments for talking about mental health openly to give young people increased opportunities for help-seeking.

A Pilot Case-Control Study of the Social Media Activity Following Cluster and Non-Cluster Suicides in Australia

Social media may play a role in the "contagion" mechanism thought to underpin suicide clusters. Our pilot case-control study presented a novel methodological approach to examining whether Facebook activity following cluster and non-cluster suicides differed. We used a scan statistic to identify suicide cluster cases occurring in spatiotemporal clusters and matched each case to 10 non-cluster control suicides. We identified the Facebook accounts of 3/48 cluster cases and 20/480 non-cluster controls and their respective friends-lists and retrieved 48 posthumous posts and replies (text segments) referring to the deceased for the former and 606 for the latter. We examined text segments for "putatively harmful" and "putatively protective" content (e.g., discussion of the suicide method vs. messages discouraging suicidal acts). We also used concept mapping, word-emotion association, and sentiment analysis and gauged user reactions to posts using the reactions-to-posts ratio. We found no "putatively harmful" or "putatively protective" content following any suicides. However, "family" and "son" concepts were more common for cluster cases and "xx", "sorry" and "loss" concepts were more common for non-cluster controls, and there were twice as many surprise- and disgust-associated words for cluster cases. Posts pertaining to non-cluster controls were four times as receptive as those about cluster cases. We hope that the approach we have presented may help to guide future research to explain suicide clusters and social-media contagion.

Das Verstärkermodell der Suizidalität: Chronische Suizidalität bei der Borderline-Persönlichkeitsstörung verstehen und behandeln

Trotz großer Fortschritte in der evidenzbasierten Psychotherapie wird unser Versorgungssystem durch chronisch suizidale Patienten mit einer Borderline-Persönlichkeitsstörung (BPS) weiterhin stark herausgefordert. Die BPS ist mit einem hohen Suizidrisiko von 5–10% sowie einem hohen Selbstverletzungsrisiko von bis zu 80% behaftet. Therapeuten wie Angehörige fühlen sich oft überfordert und hilflos, wenn sie mit der Suizidalität der Patienten konfrontiert sind. Immer wieder kommt es so zu Therapieabbrüchen, Vorstellungen in Notaufnahmen oder akut-psychiatrischen Einweisungen. Bei der nichtsuizidalen Selbstverletzung (NSSV) – einem Verhaltensmuster, das gehäuft zusammen mit chronischer Suizidalität bei BPS auftritt – tragen Verstärkermechanismen (z.B. Nachlassen von Anspannung) dazu bei, dass sich Borderline-Patienten trotz längerfristig unangenehmen Folgen immer wieder selbst verletzen. Die Motive für NSSV und suizidales Verhalten können sehr unterschiedlich sein. Es spricht jedoch einiges dafür, dass die zugrunde liegenden Mechanismen ähnlich sind und sich hieraus wichtige therapeutische Interventionsmöglichkeiten ableiten lassen. In dieser Übersichtsarbeit werden die Hintergründe und Unterschiede von NSSV, Suizidideationen sowie Suizidversuchen bei chronisch suizidalen Borderline-Patienten dargestellt. Neuere Erkenntnisse der modernen Neuro- und Verhaltenswissenschaft werden in ein Verstärkermodell der Suizidalität integriert, von dem verhaltenstherapeutische Interventionen abgeleitet werden, die Therapeuten in ihrer Arbeit mit chronisch suizidalen Patienten unterstützen können.

An Adolescent's Use of Veterinary Medicines: A Case Report Exploring Addiction

This case report describes a 17-year-old high school student serious suicide attempt using an injectable composite of veterinary medications (vitamins, vaccines, antibiotics, and antihelminthics) typically used to treat chickens. The use of this particular substance and the route of administration was novel as a method for suicide lethality and there have been no previous cases of this kind. However, this youth also developed chronic self-harming behaviors where she would repeatedly self-inject the veterinarian medication composite which included substances that were largely inert but did have a potential neuropsychiatric side effect profile that complicated her psychiatric presentation. In this context of chronically injecting a substance with unclear psychoactive properties, an interesting set of symptoms and behaviors emerged that required diagnostic clarification and interpretation. Diagnostic considerations for this youth included major depressive disorder with psychotic features, a possible emerging borderline personality disorder, post-traumatic stress disorder (PTSD), as well a possibility of an unknown substance use disorder using the veterinary medication composite. The purpose of this case study is to highlight the clinical course and explore sociocultural factors, including family and interpersonal relationships as contextually important variables.

Adolescents' knowledge of a peer's non-suicidal self-injury and own non-suicidal self-injury and suicidality

OBJECTIVE

Some research suggests that suicidal ideation and attempt among adolescents may be contagious - that is adolescents who are exposed to peers' suicidal behaviour are more likely to experience suicidal ideation or attempt suicide themselves. Less is known about the potential contagion effect of non-suicidal self-injury (NSSI). Our objective was to determine whether knowledge of a friend's NSSI is associated with adolescent's own non-suicidal self-injury and suicidal behaviours.

METHODS

Data from 1483 youth ages 14-17 years were obtained from the 2014 Ontario Child Health Study, a cross-sectional population-based survey of children and adolescents in Ontario, Canada. Logistic regression models were used to examine associations between knowledge of a friend's NSSI and adolescents' own self-reported self-injurious and suicidal behaviours. Interactions with gender, age group and presence of a mental disorder were investigated.

RESULTS

Knowledge of a friend's non-suicidal self-injury was significantly associated with the adolescent's own non-suicidal self-injury (OR = 2.03, 95% CI 1.05-3.90), suicidal ideation (OR = 3.08, 95% CI 1.50-6.30) and suicide attempt (OR = 2.87, 95% CI 1.20-6.87).

CONCLUSION

These findings suggest an apparent contagion effect for non-suicidal self-injury. Awareness of a friend's self-injurious behaviours is associated with an adolescent's own self-injury and suicidality. Interventions aimed at preventing NSSI and suicidality should consider prevention of possible contagion at the school and/or community level.

Self-determination theory in acute child and adolescent mental health inpatient care. A qualitative exploratory study

Introduction

There is a dearth of research to guide acute adolescent mental health inpatient care. Self-determination Theory provides evidence that meeting needs for relatedness, autonomy and competence is likely to increase wellbeing and intrinsic motivation. These needs may be able to be met in the inpatient environment.

Method

This qualitative study aimed to explore young people’s experience of acute mental health inpatient care with particular attention to meeting of these three needs. Fifteen young people were interviewed. The importance of relatedness with staff, other young people and families was identified.

Results

Relatedness with staff and peers were valued parts of admission. Some young people describe enhanced relatedness with family. They described loss of autonomy as a negative experience but appreciated opportunities to be involved in choices around their care and having more freedom. Coming into hospital was associated with loss of competence but they described building competence during the admission. Engaging in activities was experienced positively and appeared to enhance meeting of all three needs. Meeting of the three needs was associated with an experience of increased safety.

Conclusions

Engaging young people in activities with a focus on relatedness, autonomy and competence may have specific therapeutic potential. Autonomy, experience of competence and connection with staff may enhance safety more effectively than physical containment. Peer contact may have untapped therapeutic value we understand little of. This study supports the value of Self-determination Theory as a guide day to day inpatient care to meet the needs of adolescents for relatedness, autonomy and competence.

Understanding the characteristics and mechanisms underlying suicide clusters in Australian youth: a comparison of cluster detection methods

AIMS

There is currently no gold-standard definition or method for identifying suicide clusters, resulting in considerable heterogeneity in the types of suicide clusters that are detected. This study sought to identify the characteristics, mechanisms and parameters of suicide clusters using three cluster detection methods. Specifically, the study aimed to: (1) determine the overlap in suicide clusters among each method, (2) compare the spatial and temporal parameters associated with different suicide clusters and (3) identify the demographic characteristics and rates of exposure to suicide among cluster and non-cluster members.

METHODS

Suicide data were obtained from the National Coronial Information System. N = 3027 Australians, aged 10-24 who died by suicide in 2006-2015 were included. Suicide clusters were determined using: (1) poisson scan statistics, (2) a systematic search of coronial inquests and (3) descriptive network analysis. These methods were chosen to operationalise three different definitions of suicide clusters, namely clusters that are: (1) statistically significant, (2) perceived to be significant and (3) characterised by social links among three or more suicide descendants. For each method, the demographic characteristics and rates of exposure to suicide were identified, in addition to the maximum duration of suicide clusters, the geospatial overlap between suicide clusters, and the overlap of individual cluster members.

RESULTS

Eight suicide clusters (69 suicides) were identified from the scan statistic, seven (40 suicides) from coronial inquests; and 11 (37 suicides) from the descriptive network analysis. Of the eight clusters detected using the scan statistic, two overlapped with clusters detected using the descriptive network analysis and one with clusters identified from coronial inquests. Of the seven clusters from coronial inquests, four overlapped with clusters from the descriptive network analysis and one with clusters from the scan statistic. Overall, 9.2% (12 suicides) of individuals were identified by more than one method. Prior exposure to suicide was 10.1% (N = 7) in clusters from the scan statistic, 32.5% (N = 13) in clusters from coronial inquest and 56.8% (N = 21) in clusters from the descriptive network analysis.

CONCLUSION

Each method identified markedly different suicide clusters. Evidence of social links between cluster members typically involved clusters detected using the descriptive network analysis. However, these data were limited to the availability information collected as part of the police and coroner investigation. Communities tasked with detecting and responding to suicide clusters may benefit from using the spatial and temporal parameters revealed in descriptive studies to inform analyses of suicide clusters using inferential methods.

A 15-year follow-up of former self-harming inpatients in child & adolescent psychiatry - a qualitative study

Purpose: Self-harm is common among adolescents, and is even more frequent among psychiatric populations. The aim of this study was to increase knowledge and understanding of different aspects of life for adults who, when adolescents, had engaged in severe self-harm during inpatient stays.Material and methods: Individual semi-structured interviews were held with seven former inpatients with a history of severe self-harm during inpatient stay in their adolescence. The interviews were analysed using a qualitative method, and the results were described in the form of categories and sub-categories.Results: Five categories, with 16 sub-categories, were found to be related to the former patients' experiences of their lives. At the time of the interviews, the subjects were in their early thirties and had no ongoing self-harm. In childhood they had experienced a dysfunctional relationship with one or both of their parents, and self-harm was one of several destructive behaviours. Friendships outside the unit were difficult during adolescence. Soon after admission to the psychiatric inpatient unit, relationships with other patients became important and contributed to them wanting to stay at the unit. Meaningful relationships and being part of a social context with healthy expectations were seen as important factors for stopping self-harm at a later stage. The subjects' experiences of their life today ranged from not enjoying it to accepting their current situation.Conclusion: These findings are based on a small sample, but they indicate the importance of relationships and the social context in contributing to and then ending self-harm.

Self-injurious behavior among Greek male prisoners: Prevalence and risk factors

Background

Self-harm among prisoners is a common phenomenon. This study aims to estimate the prevalence of self-injurious behavior (SIB) among Greek male prisoners, record their motives and determine independent risk factors.

Methods

A self-administered, anonymous questionnaire was administered to 173 male prisoners in the Chalkida prison, Greece. The questionnaire included items on self-harm/SIB, demographic parameters, childhood history, family history, physical and mental disease, lifestyle and smoking habits, alcohol dependence (CAGE questionnaire), illicit substance use, aggression (Buss–Perry Aggression Questionnaire [BPAQ] and Lifetime History of Aggression [LTHA]), impulsivity (Barrat Impulsivity Scale-11) and suicidal ideation (Spectrum of Suicidal Behavior Scale). Univariate nonparametric statistics and multivariate ordinal logistic regression were performed.

Results

Of all the participants, 49.4% (95% CI: 41.5–57.3%) disclosed self-harm (direct or indirect). The prevalence of SIB was equal to 34.8% (95% CI: 27.5–42.6%). Most frequently, SIB coexisted with indirect self-harm (80.7%). The most common underlying motives were to obtain emotional release (31.6%) and to release anger (21.1%). At the univariate analysis, SIB was positively associated with a host of closely related factors: low education, physical/sexual abuse in childhood, parental neglect, parental divorce, alcoholism in family, psychiatric condition in family, recidivism, age, sentence already served, impulsivity, aggression, alcohol dependence, self-reported diagnosed psychiatric condition and illicit substance use. Childhood variables were particularly associated with the presence of diagnosed psychiatric condition. At the multivariate analysis, however, only three parameters were proven independent risk factors: self-reported diagnosed psychiatric condition, illicit substance use and aggression (BPAQ scale).

Conclusion

The prevalence of SIB is particularly high. Psychiatric condition, illicit substance use and aggression seem to be the most meaningful risk factors; childhood events seem only to act indirectly.

Function and Psychotherapy of Chronic Suicidality in Borderline Personality Disorder: Using the Reinforcement Model of Suicidality

Although great advancements in evidence-based therapies, chronic suicidal patients with borderline personality disorder (BPD) still challenge our mental health system. While BPD patients continue suffering from distress and aversive emotions, therapists and relatives feel often stunned and helpless when confronted with suicidality resulting in interruption of therapies, repeated presentations to emergency rooms and referrals to hospitals. Reviewing the current knowledge of the functions and background of non-suicidal self-injury, we learned that reinforcement mechanisms play an important role to understand why individuals act in deliberate self-mutilation. While individual motives for non-suicidal self-injury and suicidal behavior including suicidal ideations can differ, the principle mechanisms appear to be transferrable. Elucidating the individual motives and function of suicidal behavior is an important therapeutic step, giving us access to very central maladaptive schemes and false believes that we need to address in order to reduce chronic suicidality in BPD patients. This Perspective article aims to give a better idea of what is behind and what are the differences between non-suicidal self-injury, suicidal ideations and suicide attempts. It further integrates recent developments of behavioral science in a reinforcement model of suicidality that can provide therapists a practical armamentarium in their work with chronic suicidal clients.

Peer Socialization of Non-Suicidal Self-Injury in Adolescents' Close Friendships

Non-suicidal self-injury (NSSI), or self-harming behavior without intent to die (Nock Current Directions in Psychological Science, 18, 78-83, 2009), is associated with distress and impairment across domains, including increased risk for suicidality (Kiekens et al. Journal of Affective Disorders, 239, 171-179, 2018). In adolescence, prevalence of NSSI is high (Swannell et al. Suicide and Life-threatening Behavior, 44, 273-303, 2014), and peer influence regarding NSSI is thought to be strong (Brechwald and Prinstein Journal of Research on Adolescence, 21, 166-79, 2011). Although concern regarding "clusters" of NSSI has long been documented, peer socialization of NSSI in adolescence is understudied. This paper tests peer influence on NSSI frequency within adolescent friendship dyads. Emotion regulation difficulties and friendship quality were evaluated as factors that may influence susceptibility to peer influence effects. Adolescents (N = 196, M age = 15.68, 69.9% female, 87.6% White) nested within 93 friendship dyads reported on their own NSSI frequency, difficulties in emotion regulation, and friendship quality at three time points spaced 3 months apart. Cross-lagged Actor-Partner Interdependence Models examined peer influence effects over time. Friends' Time 1 frequency of NSSI uniquely predicted adolescents' own NSSI frequency over 3 and 6 months, controlling for initial similarity among friends as well as individual risk factors for NSSI. Peer influence effects were strongest in adolescents with higher levels of emotion regulation difficulty but did not vary as a function of friendship quality. Friends' NSSI frequency is a significant and unique predictor of increases in adolescents' own NSSI frequency over time. Implications for interventions that leverage the important developmental context of peer relationships are discussed.

Pediatric Nonsuicidal Self-Injury: A Call to Action for Inpatient Staff Training

The rising prevalence of nonsuicidal self-injury (NSSI) in pediatric populations along with the recent inclusion of NSSI as a condition for further study in the Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition (DSM-5) have increased the focus on the assessment and treatment of NSSI among youth. Despite the frequent occurrence of NSSI in inpatient psychiatric treatment settings, there are no empirically based assessment protocols to guide clinical staff. This article presents findings from a needs assessment conducted with staff at a state-run child and adolescent inpatient treatment facility. The purpose was to assess the need for formalized NSSI training among staff. A questionnaire was developed to evaluate whether staff had received formal training in NSSI assessment and treatment as well as typical practice responses to patients engaging in NSSI behaviors. The questionnaire also evaluated staff comfort and confidence in their knowledge and skills concerning the assessment and treatment of NSSI among children and adolescents. Respondents were 126 clinical staff, most of whom were nursing staff. Only a minority of staff reported having received formal NSSI training, and a third of respondents indicated that they do not typically assess for NSSI at all. Although a substantial percentage of clinical staff self-reported comfort and confidence with assessing and treating NSSI, fewer than 10% demonstrated accurate skill. Formal training in NSSI is associated with positive outcomes for both patients and staff in general healthcare settings. These findings suggest that similar training for staff on pediatric inpatient psychiatric units will likely foster comfort, confidence, and accuracy, thereby improving outcomes for children and adolescents engaging in NSSI behaviors.

Depressive symptoms and non-suicidal self-injury during adolescence: Latent patterns of short-term stability and change

INTRODUCTION

Depressive symptoms and non-suicidal self-injury not only increase in prevalence during adolescence, but they can also occur together. Both psychological problems seem to have similar precipitating conditions, suggesting they have transdiagnostic conditions-personal or contextual characteristics that contribute to co-occurrence. We sought to understand when these two problems co-occur and what is related to their co-occurrence.

METHODS

Using a pattern-centered approach and two waves of longitudinal data collected annually, we examined latent profiles of depressive symptoms and self-injury among a Swedish sample of adolescents aged 12 to 16 (M_ageT1 = 13.65 years, SD = 0.64), 53.7% boys and 47.3% girls. Most of the adolescents were Swedish (89%), with parents who were married or cohabitating (68%). We also examined the transitions between profiles over time.

RESULTS

Our results suggest that during this time frame, depressive symptoms and self-injury tend to emerge and stabilize or abate together. We also examined a broad array of predictors, including individual characteristics, emotion dysregulation, experiences with friends, parents' negative reactions to behavior, and school stress. The significant unique predictors suggest that adolescents who reported being subjected to relational aggression, having negative experiences while drinking, and low self-esteem had a greater probability of moving from moderate to high levels or maintaining high levels of depressive symptoms and self-injury, compared to adolescents classified in the other statuses.

CONCLUSIONS

Focusing on negative interpersonal experiences and selfesteem as transdiagnostic conditions may guide research and aid clinicians in supporting adolescents who feel depressed and engage in self-injury.

Understanding experiences of the self-harm of others: A qualitative exploration of the views of young people with complex mental health needs

As adolescent self-harm is a growing public health concern, more research is needed to identify potential risk factors. Studies have highlighted that exposure to the self-harm of others may be a risk factor associated with engagement in self-harm. However, research investigating young people's experiences of the self-harm of others has been limited. This qualitative study aimed to explore young people's experiences of the self-harm of others and interviewed a total of eight young people (five females and three males; aged between 13 and 18 years) resident at one of two adolescent mental health inpatient units in the North of England. The interviews were analysed using Interpretative Phenomenological Analysis and four themes were identified: 'Pre-admission exposure to self-harm', 'Exposure on the inside: An unpleasant environment', 'Helper vs helped' and 'Separation from the attention seekers: competing for authenticity'. Prevention efforts to reduce the social transmission and stigma surrounding self-harm among young people are discussed.

Self-harm in adolescent in-patients

Aims and Method

Self-harm among adolescent in-patients exercises all who work with them. the UK has an exceptionally high prevalence of this behaviour compared with the rest of Europe. However, in one in-patient adolescent unit, in-patient self-harm was significantly reduced. Details of our rationale and intervention are presented, together with a retrospective data analysis.

Results

Using a range of practical and psychological interventions, the alarmingly high level of self-harm was almost completely eliminated and this level has been maintained to the present.

Clinical Implications

Our results suggest that self-harm in in-patients can be managed and reduced without adverse effects on the patients. Our methods may be applicable to other settings, although some staff may initially feel uncomfortable with such policy.

Residential staff responses to adolescent self-harm: The helpful and unhelpful

Adolescent self-harm is prevalent in residential and secure care and is the cause of distress to those harming themselves, to the staff caring for them and for other young people living with them. This article sought service user views on what staff supports were effective and what were counter-productive in order to improve the care offered to young people. Seven young people living in residential or secure care were interviewed. Thematic analysis was used to elicit key themes. Global themes of safety and care were elicited. The young people understood and accepted that the role of staff was to provide these. Within these themes, they noted numerous responses that had both helpful and unhelpful effects, including increased observation, removal of means and extra collaborative support. Service users made numerous recommendations to increase the helpful effects of staff support. Young people provided informed and helpful guidance on how best to care for them. Their views can help mental health professionals and care staff increase their helpful responses making them more effective and less counter-productive. This study is a rare representation of the views of young people in residential and secure care and how to respond to their self-harm behaviour.

Practitioners' experiences of adolescent suicidal behaviour in peer groups

WHAT IS KNOWN ON THE SUBJECT?: Group suicidal behaviour can be devastating for all concerned. There is an absence of research on adolescent suicidal group behaviour. The perspectives of practitioners' experiences of these groups are largely lacking from research literature. WHAT THIS PAPER ADDS TO EXISTING KNOWLEDGE?: Practitioners work regularly with suicidal behaviour in adolescent peer groups. Practitioners identify peer relationships in groups as complex, including elements that are both suicide encouraging and preventing. Practitioners identify a range of ways in which young people become involved in suicidal behaviour in groups, including indirectly through risk taking and care-seeking as well as directly suicidal or self-harming. WHAT ARE THE IMPLICATIONS FOR PRACTICE?: Assessments of young people should routinely include a focus on the qualities of peer relations, including those in the online/digital realm. Assessments and interventions need to consider the complexity of group relationships and roles, and the multiplicity of factors that can contribute to suicidal behaviour in groups. Interventions that sustain therapeutic connectedness are helpful for taking dynamic/fluctuating risks into account.

ABSTRACT

Introduction Group suicidal behaviour by young people can have harmful effects; it may be increasing, influenced by online media and reported increasing self-harm rates; new knowledge and understanding to inform interventions is required. Aim To explore how practitioners experience group suicidal behaviour amongst adolescents, how they assess risks/needs, and how these insights inform understanding about these groups. Method Ten practitioners, including Mental Health Nurses, were interviewed in one multidisciplinary CAMHS, in England. Data analysis was by Thematic Analysis (Braun & Clarke 2006). Results Participants described frequently working with suicidal groups. Roles in groups include suicide encouraging and preventing. Practitioners identify risky and protective connections between young people, online and offline. Clinical tensions include living with suicidal risks, emotional and positional challenges, and getting to grips with digital media. Discussion Peer groups appear to have a larger role in adolescent suicide than recognized to date. Practitioners need to assess young people's roles in groups, their diverse motivations and to understand constantly changing digital media. Implications for practice Assessments of suicide risk for young people should routinely include focus on peer relations including the online/digital realm. Maintaining relationships with vulnerable young people facilitates managing fluctuating risks and understanding different group dynamics.

The Social Norms of Suicidal and Self-Harming Behaviours in Scottish Adolescents

Although the suicidal and self-harming behaviour of individuals is often associated with similar behaviours in people they know, little is known about the impact of perceived social norms on those behaviours. In a range of other behavioural domains (e.g., alcohol consumption, smoking, eating behaviours) perceived social norms have been found to strongly predict individuals' engagement in those behaviours, although discrepancies often exist between perceived and reported norms. Interventions which align perceived norms more closely with reported norms have been effective in reducing damaging behaviours. The current study aimed to explore whether the Social Norms Approach is applicable to suicidal and self-harming behaviours in adolescents. Participants were 456 pupils from five Scottish high-schools (53% female, mean age = 14.98 years), who completed anonymous, cross-sectional surveys examining reported and perceived norms around suicidal and self-harming behaviour. Friedman's ANOVA with post-hoc Wilcoxen signed-ranks tests indicated that proximal groups were perceived as less likely to engage in or be permissive of suicidal and self-harming behaviours than participants' reported themselves, whilst distal groups tended towards being perceived as more likely to do so. Binary logistic regression analyses identified a number of perceived norms associated with reported norms, with close friends' norms positively associated with all outcome variables. The Social Norms Approach may be applicable to suicidal and self-harming behaviour, but associations between perceived and reported norms and predictors of reported norms differ to those found in other behavioural domains. Theoretical and practical implications of the findings are considered.

Variation between hospitals in inpatient admission practices for self-harm patients and its impact on repeat presentation

PURPOSE

Self-harm patient management varies markedly between hospitals, with fourfold differences in the proportion of patients who are admitted to a medical or psychiatric inpatient bed. The current study aimed to investigate whether differences in admission practices are associated with patient outcomes (repeat self-harm) while accounting for differences in patient case mix.

METHODS

Data came from the National Self-Harm Registry Ireland. A prospective cohort of 43,595 self-harm patients presenting to hospital between 2007 and 2012 were included. As well as conventional regression analysis, instrumental variable (IV) methods utilising between hospital differences in rates of hospital admission were used in an attempt to gain unbiased estimates of the association of admission with risk of repeat self-harm.

RESULTS

The proportion of self-harm patients admitted to a medical bed varied from 10 to 74 % between hospitals. Conventional regression and IV analysis suggested medical admission was not associated with risk of repeat self-harm. Psychiatric inpatient admission was associated with an increased risk of repeat self-harm in both conventional and IV analyses. This increased risk persisted in analyses stratified by gender and when restricted to self-poisoning patients only.

CONCLUSIONS

No strong evidence was found to suggest medical admission reduces the risk of repeat self-harm. Models of health service provision that encourage prompt mental health assessment in the emergency department and avoid unnecessary medical admission of self-harm patients appear warranted. Psychiatric inpatient admission may be associated with a heightened risk of repeat self-harm in some patients, but these findings could be biased by residual confounding and require replication.

What do we know about the risks for young people moving into, through and out of inpatient mental health care? Findings from an evidence synthesis

BACKGROUND

Young people with complex or severe mental health needs sometimes require care and treatment in inpatient settings. There are risks for young people in this care context, and this study addressed the question: 'What is known about the identification, assessment and management of risk in young people (aged 11-18) with complex mental health needs entering, using and exiting inpatient child and adolescent mental health services in the UK?'

METHODS

In phase 1 a scoping search of two electronic databases (MEDLINE and PsychINFO) was undertaken. Items included were themed and presented to members of a stakeholder advisory group, who were asked to help prioritise the focus for phase 2. In phase 2, 17 electronic databases (EconLit; ASSIA; BNI; Cochrane Library; CINAHL; ERIC; EMBASE; HMIC; MEDLINE; PsycINFO; Scopus; Social Care Online; Social Services Abstracts; Sociological Abstracts; OpenGrey; TRiP; and Web of Science) were searched. Websites were explored and a call for evidence was circulated to locate items related to the risks to young people in mental health hospitals relating to 'dislocation' and 'contagion'. All types of evidence including research, policies and service and practice responses relating to outcomes, views and experiences, costs and cost-effectiveness were considered. Materials identified were narratively synthesised.

RESULTS

In phase 1, 4539 citations were found and 124 items included. Most were concerned with clinical risks. In phase 2, 15,662 citations were found, and 40 addressing the risks of 'dislocation' and 'contagion' were included supplemented by 20 policy and guidance documents. The quality of studies varied. Materials were synthesised using the categories: Dislocation: Normal Life; Dislocation: Identity; Dislocation: Friends; Dislocation: Stigma; Dislocation: Education; Dislocation: Families; and Contagion. No studies included an economic analysis. Although we found evidence of consideration of risk to young people in these areas we found little evidence to improve practice and services.

CONCLUSIONS

The importance to stakeholders of the risks of 'dislocation' and 'contagion' contrasted with the limited quantity and quality of evidence to inform policy, services and practice. The risks of dislocation and contagion are important, but new research is needed to inform how staff might identify, assess and manage them.

What happens when you tell someone you self-injure? The effects of disclosing NSSI to adults and peers

BACKGROUND

Non-suicidal self-injury (NSSI) is associated with significant adverse consequences, including increased risk of suicide, and is a growing public health concern. Consequently, facilitating help-seeking in youth who self-injure is an important goal. Although young people who disclose their NSSI typically confide in peers and family, it is unclear how this disclosure and related variables (e.g. support from family and friends, coping behaviours, reasons for living) affect help-seeking over time. The aim of this study was to advance understanding of the impact of disclosure of NSSI by young people and to investigate these effects over time.

METHODS

A sample of 2637 adolescents completed self-report questionnaires at three time points, one year apart.

RESULTS

Of the sample, 526 reported a history of NSSI and 308 of those who self-injured had disclosed their behaviour to someone else, most commonly friends and parents.

CONCLUSIONS

Overall, we observed that disclosure of NSSI to parents facilitates informal help-seeking, improves coping and reduces suicidality, but that disclosure to peers might reduce perceived social support and encourage NSSI in others. We discuss these findings in light of their clinical and research implications.

Conceptualizing the neurobiology of non-suicidal self-injury from the perspective of the Research Domain Criteria Project

Non-suicidal self-injury (NSSI) commonly starts in adolescence and is associated with an array of negative outcomes. Neurobiological research investigating NSSI is in its early stages and most studies have examined this behavior within the context of specific diagnoses. However, the Research Domain Criteria (RDoC) initiative encourages researchers to examine brain-behavior relationships across diagnoses. This review on the neurobiology associated with NSSI is organized using the domains proposed by RDoC: Negative Valence, Positive Valence, Cognitive, Social Processes, and Arousal/Regulatory Systems. Evidence of neurobiological anomalies is found in each of these domains. We also propose future research directions, especially in regard to human development. Future NSSI studies should address this behavior independent of diagnosis, examine relevant constructs across multiple units of analysis, and assess how systems change across development and course of illness. These advances will be essential for guiding neurobiologically informed intervention and prevention strategies to target NSSI. In doing so, we may prevent the associated negative outcomes across the lifespan.

Nonsuicidal Self-Injury in Adolescents

Abstract. Nonsuicidal self-injury (NSSI) is a prevalent, pervasive, clinically significant behavior in adolescents, frequently associated with serious social, physical, and psychological consequences. It is characterized by high comorbidity with various disorders. Therefore, NSSI has been included as a research diagnosis in the Diagnostic and statistical manual of mental disorders (5th ed., American Psychiatric Association (APA; 2013) ; DSM-5; Section 3), as a condition requiring further study for possible future official adoption. This is a positive step toward providing researchers with a uniform definition and criteria. This state-of-the-art article gives an overview of prevalence rates, comorbidity, clinical correlates, functions, and risk factors as well as treatment and dealing with adolescents with NSSI and their Internet activities. Furthermore, the association and differences between NSSI and suicidality as well as borderline personality disorder are reviewed. The article concludes with future directions for research, for example, the dimensional approach to classification of the Research Domain Criteria project.

An evidence synthesis of risk identification, assessment and management for young people using tier 4 inpatient child and adolescent mental health services

Background

Inpatient child and adolescent mental health services are one part of a complex system, and exist to meet the needs of young people with the greatest mental health difficulties.

Objectives

The research question was ‘What is known about the identification, assessment and management of risk (where “risk” is broadly conceived) in young people (aged 11–18 years) with complex mental health needs entering, using and exiting inpatient child and adolescent mental health services in the UK?’

Data sources

The two-phase Evidence for Policy and Practice Information and Co-ordinating Centre approach was used. In phase 1, scoping searches were made using two databases with an end date of March 2013. Phase 2 centred on the search for citations relating to the risks to young people of ‘dislocation’ and ‘contagion’. Searches were made using 17 databases, with time limits from 1995 to September 2013. Websites were searched, a call for evidence circulated and references of included citations reviewed.

Review methods

Priority risk areas for phase 2 were decided in collaboration with stakeholders including through consultations with young people and the mother of a child who had been in hospital. All types of evidence relating to outcomes, views and experiences, costs and cost-effectiveness, policies, and service and practice responses in the areas of ‘dislocation’ and ‘contagion’ for young people (11–18 years) using inpatient mental health services were considered. A staged approach to screening was used. Data were extracted into tables following guidance from the Centre for Reviews and Dissemination or tables developed for the review. Quality was assessed using appraisal checklists from the Effective Public Health Practice Project or the Critical Skills Appraisal Programme or devised by previous reviewers. No papers were excluded on the grounds of quality, and all materials identified were narratively synthesised.

Results

In phase 1, 4539 citations were found and 124 included. Most were concerned with clinical risks. In phase 2, 15,662 citations were found and 40 addressing the less obvious risks of ‘dislocation’ and ‘contagion’ were included, supplemented by 20 policy and guidance documents. These were synthesised using these categories: Dislocation: Normal Life; Dislocation: Identity; Dislocation: Friends; Dislocation: Stigma; Dislocation: Education; Dislocation: Families; and Contagion. No studies included an economic analysis or economic evaluation. The importance to stakeholders of these less obvious risks contrasted with the limited quantity and quality of research capable of informing policy, services and practice in these areas.

Limitations

Included studies were of variable quality. Data derived could not be used to inform an economic modelling of NHS costs or to analyse cost-effectiveness. Other limitations were the search for only English-language materials and the use of umbrella concepts (‘dislocation’ and ‘contagion’).

Conclusions

The less obvious risks are important, but little evidence exists to support their identification, assessment and management. This has implications for services, and a programme of research is recommended to generate new knowledge.

The definition and epidemiology of clusters of suicidal behavior: a systematic review

Suicide clusters are a rare and underresearched phenomenon which attract wide media attention and result in heightened concern in the communities where they occur. We conducted a systematic literature review covering the definition and epidemiology of the time-space clustering of suicidal behavior. Of the 890 articles identified by electronic searching, 82 were selected for inclusion and the extracted data were analyzed by narrative synthesis. Less than a third of studies included a definition of a suicide cluster, and definitions varied considerably. Clusters occurred in various settings, including psychiatric hospitals, schools, prisons, indigenous communities, and among the general population. Most clusters involved young people. The proportion of all episodes that occurred in clusters varied considerably between studies and partly depended on study methodology (e.g., a larger proportion was found in studies of specific clusters compared with general population studies). Future studies should aim to combine the statistical analysis of time-space clustering with a case study of events, which examines potential links between individuals and the wider environmental context.

Suicide contagion: a systematic review of definitions and research utility

Objectives

Despite the common use of contagion to analogize the spread of suicide, there is a lack of rigorous assessment of the underlying concept or theory supporting the use of this term. The present study aims to examine the varied definitions and potential utility of the term contagion in suicide-related research.

Methods

100 initial records and 240 reference records in English were identified as relevant with our research objectives, through systematic literature screening. We then conducted narrative syntheses of various definitions and assessed their potential value for generating new research.

Results

20.3% of the 340 records used contagion as equivalent to clustering (contagion-as-cluster); 68.5% used it to refer to various, often related mechanisms underlying the clustering phenomenon (contagion-as-mechanism); and 11.2% without clear definition. Under the category of contagion-as-mechanism, four mechanisms have been proposed to explain how suicide clusters occurred: transmission (contagion-as-transmission), imitation (contagion-as-imitation), contextual influence (contagion-as-context), and affiliation (contagion-as-affiliation). Contagion-as-cluster both confounds and constrains inquiry into suicide clustering by blending proposed mechanism with the phenomenon to be studied. Contagion-as-transmission is, in essence, a double or internally redundant metaphor. Contagion-as-affiliation and contagion-as-context involve mechanisms that are common mechanisms that often occur independently of apparent contagion, or may serve as a facilitating background. When used indiscriminately, these terms may create research blind spots. Contagion-as-imitation combines perspectives from psychology, sociology, and public health research and provides the greatest heuristic utility for examining whether and how suicide and suicidal behaviors may spread among persons at both individual and population levels.

Conclusion

Clarifying the concept of “suicide contagion” is an essential step for more thoroughly investigating its mechanisms. Developing a clearer understanding of the apparent spread of suicide-promoting influences can, in turn, offer insights necessary to build the scientific foundation for prevention and intervention strategies that can be applied at both individual and community levels.

The best friend and friendship group influence on adolescent nonsuicidal self-injury

This study examined associations of peer socialization and selection, over time, with nonsuicidal self-injury (NSSI) among 5,787 (54.2 % females) Chinese community adolescents. Both effects were tested using two aspects of adolescents' friendship networks: the best friend and the friendship group. Participants completed questionnaires assessing NSSI, depressive symptoms and maladaptive impulsive behaviors at two waves of time over a 6-month period. Results showed that even after controlling for the effects of depressive symptoms and maladaptive impulsive behaviors, the best friends' engagement in NSSI still significantly predicted adolescents' own engagement in NSSI. Adolescents' friendship groups' NSSI status also significantly predicted their own NSSI status and frequency. Additionally, adolescents with NSSI tended to join peer groups with other members also engaging in NSSI.

The role of exposure to self-injury among peers in predicting later self-injury

While researchers are beginning to reach consensus around key psychological correlates of non-suicidal self-injury (NSSI), comparatively less work has been done investigating the role and influence of peers. Given evidence that engagement in this behavior may be susceptible to peer influence, especially during the early stages of its course, the current study prospectively explored whether knowing a friend who self-injures is associated with the onset, severity, and subsequent engagement in NSSI. The moderating roles of adverse life events, substance use and previous suicidal behavior in this relationship also were explored. Self-report data were collected from 1,973 school-based adolescents (aged 12-18 years; 72 % female) at two time points, 1 year apart. Knowing a friend who self-injured, negative life events, psychological distress and thoughts of NSSI differentiated those who self-injured from those who did not, and also predicted the onset of NSSI within the study period. Further, adverse life events and previous thoughts of NSSI moderated the relationship between exposure to NSSI in peers and engaging in NSSI at Time 2. However, the effect of having a friend who self-injures was not related to the severity of NSSI. Having a friend who self-injures appears to be a risk factor for self-injury among youth who are experiencing high levels of distress. Implications of these findings are discussed.

Can sociocultural and historical mechanisms influence the development of borderline personality disorder?

Borderline personality disorder (BPD) is a common and severe clinical problem. While cross-cultural research suggests that this condition can be identified in different societies, indirect evidence suggests that BPD and some of its associated symptoms (suicidality and self-harm) have a higher prevalence in developed countries. If so, sociocultural and historical mechanisms may have influenced the development of the disorder. While the vulnerabilities underlying BPD are broad and nonspecific, specific symptoms can be shaped by culture. The mechanisms involve the influence of a "symptom bank," as well as the role of social contagion. These trends may be related to a decrease in social cohesion and social capital in modern societies.

The impact of social contagion on non-suicidal self-injury: a review of the literature

In this review, we explore social contagion as an understudied risk factor for non-suicidal self-injury (NSSI) among adolescents and young adults, populations with a high prevalence of NSSI. We review empirical studies reporting data on prevalence and risk factors that, through social contagion, may influence the transmission of NSSI. Findings in this literature are consistent with social modeling/learning of NSSI increasing risk of initial engagement in NSSI among individuals with certain individual and/or psychiatric characteristics. Preliminary research suggests iatrogenic effects of social contagion of NSSI through primary prevention are not likely. Thus, social contagion factors may warrant considerable empirical attention. Intervention efforts may be enhanced, and social contagion reduced, by implementation of psychoeducation and awareness about NSSI in schools, colleges, and treatment programs.

[How do adolescents view non-suicidal self-injury? Differences between affected and non-affected adolescents in a school sample]

Despite the growing number of epidemiologic studies about the prevalence of non-suicidal self-injury (NSSI), little knowledge exists regarding the way adolescents view NSSI, whether differences in the attitudes towards NSSI between affected and non-affected adolescents exist and whether the acquaintance with adolescents engaging in NSSI influence one's attitudes towards self-injury? In an epidemiological study of non-suicidal self-injury, we assessed the attitudes of 447 ninth grade students (age 15 years SD = 0.7, 52% male) NSSI using a self-constructed questionnaire with three factors. Sixty one (13.6%) pupils reported that they had intentionally injured themselves once in their life time. 43% (n = 179) indicated that they discuss the topic with others, though over half of these pupils 54% (n = 98) stated feeling burdened by discussions with friends affected by NSSI. Comparisons between affected and non-affected adolescents revealed that adolescents who had never exhibited NSSI tend to believe that NSSI is mostly interpersonally motivated. Moreover, the adolescents affected by NSSI assessed the emotional reaction as more appropriate than non-affected adolescents. This should be considered in the design and refinement of inpatient treatment concepts. Our results suggest focusing on intrapersonal motives in psychotherapeutic sessions and reducing interpersonal motives for self-injurious behaviour through the establishment of clear and transparent milieu therapeutic structural conditions.

Examining the Acceptability, Attractiveness, and Effects of a School-Based Validating Interview for Adolescents Who Self-Injure

Nonsuicidal self-injury (NSSI) in adolescents is a significant problem that needs to be addressed, and in some cases managed, in school settings. The current feasibility study uses screening questionnaires and follow up-interviews on NSSI in a community sample of adolescents ( N = 1,052) in Sweden. Both adolescents reporting self-injury ( n = 66) and a comparison group ( n = 31) were interviewed, and information disclosed about self-injury, as well as the results from the interviewers assessments of the seriousness of these behaviors, were examined. Generally, adolescents reported positive feelings about being interviewed, and 52% of those who had reported self-injury in the questionnaire disclosed NSSI in the interviews. Further, a majority of these cases, 76%, were not assessed as very serious. When NSSI was reported in a questionnaire 1 year after the interview, there were no indications of iatrogenic effects from participating in the interview. The results support the feasibility of using NSSI screening questionnaires in combination with follow-up interviews in schools.
