Exposure to patient aggression and health outcomes for forensic mental health nurses: A cross-sectional survey.

AIMS: The aims of the study were to determine the types and prevalence of forensic mental health nurse exposure to patient aggression and explore the impact of these exposures on their physical and mental health and work absences. DESIGN: Cross-sectional survey conducted January to April 2020. METHODS: All 205 nurses working in an Australian high-security inpatient forensic mental health hospital were invited to participate. An online survey included the Perception of Prevalence of Aggression Scale to measure respondent exposure to types of patient aggression, and the SF-36v2 to measure mental and physical health. Absence from work and other work and individual characteristics were also explored. RESULTS: Sixty-eight respondents completed the survey. Verbal abuse was the most experienced aggression type, followed by physical violence and observing violence, patient self-harming behaviours and sexual violence. Nurses who worked in acute units experienced significantly more exposure to overall aggression than nurses in non-acute units. Higher level of aggression was associated with number of days sick leave taken and days off due to aggression or violence. Higher level of aggression was associated with poorer mental health, and patient self-harming behaviour was associated with poorer physical health. CONCLUSIONS: Nurses in acute units experience higher levels of inpatient aggression and are therefore at increased risk of being impacted by the exposure. Findings indicate a psychological impact of exposure to frequent aggression and potential for an accumulative effect of exposure to traumatic events on nurse well-being. Nurses who are victim of, or witness, physical violence are most likely to take time off work. IMPACT: This study provides further evidence that forensic mental health nurses are frequently exposed to various forms of patient aggression. For some nurses, this exposure to patient aggression negatively impacted their mental and physical health. Employing organizations should therefore prioritize provision of formal support for nurses. No patient or public contribution.

The functions of self-harm in young people and their perspectives about future general practitioner-led care: A qualitative study.

BACKGROUND: Self-harm in young people is a serious concern but a deeper understanding of the functions of self-harm in young people can tailor care and inform new clinical interventions to reduce repeat self-harm and suicide risk. General practitioners (GPs), as frontline healthcare professionals, have an important role in managing self-harm in young people. This study aimed to explore the functions of self-harm in young people and their perspectives on future GP-led care. METHODS: A qualitative study using interviews with young people aged between 16 and 25 years with a personal history of self-harm was conducted. Interviews were transcribed and analysed using reflexive thematic analysis. FINDINGS: Four distinct functions were identified: (1) handling emotional states; (2) self-punishment; (3) coping with mental illness and trauma; and (4) positive thoughts and protection. Young people valued GP-led support and felt future GP interventions should include self-help and be personalised. CONCLUSIONS: These findings support clinicians, including GPs, to explore the functions of self-harm in young people aged 16-25 in a personalised approach to self-harm care. It should be noted that self-harm may serve more than one function for a young person and thus interventions should recognise this. PATIENT AND PUBLIC CONTRIBUTION: A group consisting of young people with lived experience of self-harm, carers, the public, and those who work with young people who harm themselves conceived this study idea, informed recruitment methods and the interview topic guide, and supported the interpretation of findings.

Healthcare visits for mental disorders and use of psychotropic medications before and after self-harm in a cohort aged 75.

OBJECTIVES: Non-fatal self-harm (SH) is a major risk factor for late-life suicide. A better knowledge of the clinical management of older adults who self-harm is needed to establish where improvements could be made for the implementation of effective suicide prevention interventions. We therefore assessed contacts with primary and specialised care for mental disorders and psychotropic drug use during the year before and after a late-life non-fatal SH episode. METHOD: Longitudinal population-based study in adults aged ≥75 years with SH episode between 2007 and 2015 retrieved from the regional database VEGA. Healthcare contacts for mental disorders and psychotropic use were assessed during the year before and after the index SH episode. RESULTS: There were 659 older adults who self-harmed. During the year before SH, 33.7% had primary care contacts with a mental disorder, 27.8% had such contacts in specialised care. Use of specialised care increased sharply after the SH, reaching a maximum of 68.9%, but this figure dropped to 19.5% by the end of the year. Use of antidepressants increased from 41% before to 60% after the SH episode. Use of hypnotics was extensive before and after SH (60%). Psychotherapy was rare in both primary and specialised care. CONCLUSION: The use of specialised care for mental disorders and antidepressant prescribing increased after SH. The drop in long-term healthcare visits should be further explored to align primary and specialised healthcare to the needs of older adults who self-harmed. The psychosocial support of older adults with common mental disorders needs to be strengthened.

The relationship between traumatic dental injuries and adolescents' non-suicidal self-injury behaviour: A cross-sectional analysis of an East London cohort.

BACKGROUND/AIM: Recent reviews of case reports have pointed out a potential connection between non-suicidal self-injury (NSSI) and traumatic dental injuries (TDIs). The aim of this study was to investigate the association of a history of NSSI with TDIs in 15- to 16-year-old adolescents. METHODS: This study analysed cross-sectional data from the Research with East London Adolescents Community Health Survey, a prospective population survey of adolescents attending state schools in East London, England. The history of NSSI was obtained using two items from the Lifestyle and Coping questionnaire (whether they have ever engaged with self-harm and the last time they engaged in such behaviours). The presence of TDIs, increased overjet and inadequate lip coverage were determined through clinical assessments by two trained dentists. Survey logistic regression was fitted to test the association of NSSI with TDIs. Odds ratios (ORs) were adjusted for socio-demographic and clinical characteristics as potential confounders. RESULTS: The lifetime and last-year prevalence of NSSI were 11.9% and 6.7%, respectively, whereas the prevalence of TDIs was 16.5%. Neither the lifetime prevalence of NSSI (OR: 1.02, 95% confidence interval: 0.56-1.85) nor the last-year prevalence of NSSI (OR: 0.76, 95% CI: 0.36-1.61) were associated with TDIs in regression models adjusted for confounders. CONCLUSION: This study did not support an association between history of NSSI and TDIs among adolescents aged 15-16 years old in East London.

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.

Suicide-related crisis presentations to a rural emergency department: A retrospective cohort study.

OBJECTIVE: The study sought to investigate the profile and characteristics of suicide-related crisis presentations and factors associated with repeat presentations to a rural hospital Emergency Department (ED). METHOD: This retrospective cohort study examined suicide-related crisis presentation data from a rural ED for the years 2008-2018 inclusive. Descriptive statistical analyses included demographic characteristics and trends over time. Factors associated with increased likelihood to re-present to the ED for suicide-related crisis were identified using Odds Ratio analyses. RESULTS: First Nations People, adolescents and young adults were at increased risk of presentation. Suicidal crisis presentations had increased well beyond that which might be accorded to the catchment's population increase and almost a third of presentations involved individuals re-presenting in suicide-related crisis. Repeat presentation was positively associated with younger age, less acute triage category, discharge to the community and leaving the ED before/during treatment. CONCLUSIONS: This study illustrates the importance of flagging, follow-up and support of rural repeat presenters to reduce further suicidal behaviours and presentation. Findings support the need for culturally safe and appropriate interventions and follow-up services. It is recommended to extend approach this to non-ED settings.

Review: Systematic review and metasynthesis of qualitative literature on young people's experiences of going to A&E/emergency departments for mental health support.

BACKGROUND: There has been an increase in children and young people attending emergency departments for mental health reasons, including self-harm. Patients often report having poor experiences when attending emergency departments for mental health support. However, there has yet to be a review exploring the experiences of young people. Our aim in this study was to synthesise qualitative literature on young people's experiences of going to emergency departments for mental health support. METHODS: A systematic review and metasynthesis were conducted. Five databases and grey literature were searched for relevant studies. Five articles met study criteria and were analysed using an iterative process of thematic synthesis. RESULTS: The synthesis yielded four overarching themes: (a) emergency departments' inability to meet the mental health needs of young people, (b) emergency departments exacerbating patient distress, (c) patients feeling like a burden or undeserving of treatment and (d) consequences of poor emergency department experiences. CONCLUSIONS: These findings (based on a still very limited literature) highlight the role that emergency departments have in relation to being a key point of contact with young people who self-harm. To properly engage with patients, emergency departments need to have the resources to provide compassionate care and follow clinical guidelines regarding assessments.

Men who self-harm-A scoping review of a complex phenomenon.

BACKGROUND: To understand and care for men who self-harm, it is important that healthcare professionals have understanding of how and why men self-harm, men's experiences of self-harm and what can be done to hinder or prevent self-harm. AIMS: The aim of this study was to synthesize the existing knowledge on men who self-harm, with a special emphasis on background, self-harming methods, experiences and reported therapeutic interventions and/or care approaches. DESIGN: Scoping review of internationally published and grey literature, based on a methodological framework by Arksey and O'Malley. DATA SOURCES: Systematic electronic database searches were conducted in CINAHL, MEDLINE (Ovid) and PsycINFO. From a total of 684 studies found, 24 studies met the inclusion criteria: full-text, published in English, peer-reviewed studies and grey literature including a focus on men who self-harm, men aged between 18 and 65 years, and published between 2010 and 2019. RESULTS: Men's self-harm was understood as being related to mental disorders, a means of affect regulation, a loss of self-control, and a means of interpersonal communication. Self-harm can be a positive or negative experience, and there is a wide variety in the methods that men use to self-harm: sharp objects, injection, ingestion, without aids or riskful behaviour. Few studies reported on therapeutic interventions and/or care approaches for men who self-harm. CONCLUSION: Men's self-harm should be understood as a complex, socially and culturally conditioned phenomenon and studied from a multitude of perspectives. IMPACT: This scoping review concludes that self-harm among men should be understood as a complex, socially and culturally conditioned phenomenon. To empower men and support their recovery from self-harm, a person-centred approach should be incorporated into research on the subject and practice.

Professionals' attitudes towards people with intellectual disabilities who self-harm: A literature review.

BACKGROUND: National Institute for Health and Care Excellence (NICE, 2013) Guidance on Self-Harm states that professionals supporting people who self-harm should demonstrate compassion, respect and dignity. This literature review examines the evidence for professionals' attitudes towards people with intellectual disabilities who self-harm. METHOD: Four databases (PsychInfo, IBSS, CINAHL and Medline) were systematically searched to find relevant research since 2000. RESULTS: Four studies met the criteria. Attitudes of professionals supporting people with intellectual disabilities are contrasted with those of professionals in settings focused on supporting people without intellectual disabilities. Professionals supporting people with intellectual disabilities tended to display attitudes and attributions reflective of biobehavioural and psychosocial theories of self-harm, with a greater emphasis on relationships. CONCLUSION: Much more research is needed which examines the attitudes of professionals supporting people with intellectual disabilities who self-harm.

Behavioural, psychiatric and psychosocial factors associated with aggressive behaviour in adults with intellectual disabilities: A systematic review and narrative analysis.

BACKGROUND: Aggressive behaviour is prevalent in people with intellectual disabilities. To understand the aetiology, it is important to recognize factors associated with the behaviour. METHOD: A systematic review was conducted and included studies published between January 2002 and April 2017 on the association of behavioural, psychiatric and psychosocial factors with aggressive behaviour in adults with intellectual disabilities. RESULTS: Thirty-eight studies were included that presented associations with 11 behavioural, psychiatric and psychosocial factors. Conflicting evidence was found on the association of these factors with aggressive behaviour. CONCLUSIONS: The aetiology of aggressive behaviour is specific for a certain person in a certain context and may be multifactorial. Additional research is required to identify contributing factors, to understand causal relationships and to increase knowledge on possible interaction effects of different factors.

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.

Investigating the role of hallucinatory experiences in the transition from suicidal thoughts to attempts.

OBJECTIVE: Psychotic experiences, including auditory hallucinatory experiences (HEs), are strongly associated with both suicidal thoughts and behaviour. This study examined their role in the ideation-to-attempt transition in adolescents, including their direct and indirect effect via potential mediators. METHOD: Participants were from an Australian prospective longitudinal cohort of 1669 adolescents (12-17 years); of which a subsample endorsing baseline suicidal ideation (n = 216) was the focus of most analyses. Suicidal thoughts and behaviours were measured using the Self-Harm Behaviour Questionnaire. The Diagnostic Interview Schedule for Children was used to assess auditory HEs. Potential mediators of interest were psychological distress and Interpersonal Theory of Suicide (IPTS) constructs. RESULTS: Among adolescents reporting suicidal ideation at baseline (n = 216), 6.5% had attempted suicide during follow-up. The size of auditory HEs' univariate effect suggests a possible strong relationship with increased risk of incident suicide attempts (OR = 2.40; 95%CI = 0.76-7.56); however, there was inadequate statistical power to produce a precise estimate. When HEs were accompanied by distress there was a nine-fold increased risk of acting on suicidal thoughts. Distress was independently associated with risk of attempt transition (OR = 4.09), whereas IPTS constructs were poor explanatory variables in most models. CONCLUSION: Adolescents with psychological distress and auditory HEs are at high risk of incident suicide attempts. Further investigations on the role of negative/distressing content of hallucinations in the ideation-to-attempt transition are warranted.

The use of stimulants in depression: Results from a self-controlled register study.

OBJECTIVE: To investigate the effectiveness of stimulants in patients with depression, by using naturalistic outcome measures, such as psychiatric admissions, psychiatric bed-days and incidents of intentional self-harm or suicide attempts. METHODS: Via linkage of the Danish nationwide health registers, we identified all patients with a diagnosis of depression initiating stimulants, including methylphenidate, modafinil, amphetamine, dexamphetamine or lisdexamphetamine, from 1995 to 2012. We used a mirror-image model to test whether redemption of a stimulant prescription was associated with a reduction in psychiatric admissions, inpatient days and incidents of intentional self-harm or suicide attempts. Specifically, the number of these outcomes in the 2 years leading up to redemption of a stimulant prescription was compared to the two subsequent years. Similar outcomes were used in a reverse mirror-image model to investigate the effect of stimulant termination. RESULTS: A total of 3354, 935 and 105 patients diagnosed with depression redeemed prescriptions for methylphenidate, modafinil or amphetamine/dexamphetamine/lisdexamphetamine, respectively. Initiation of methylphenidate was not associated with a significant change in psychiatric admissions (mean: -0.02 admissions, p = 0.11) or inpatient days (mean: 0.13 days, p = 0.74). Similar findings were made for modafinil and the amphetamines. In addition, no clinically relevant change in psychiatric admissions or inpatient days was found after termination of a stimulant. After initiation of methylphenidate, the incidents of self-harm or suicide attempts were reduced by 54%, from 68 to 31 events (p = 0.004). No significant change in incidents of self-harm or suicide attempts were found for modafinil or the amphetamines. CONCLUSION: This nationwide study, using naturalistic outcomes, does not support the use of stimulants in patients with depression. However, the use of methylphenidate was associated with a 54% reduction in incidents of self-harm or suicide attempts, indicating that methylphenidate may potentially be useful in patients with depression with suicidal- or self-harming behaviour. However, further studies are needed, before any firm conclusions can be made.

A randomised trial of dialectical behaviour therapy and the conversational model for the treatment of borderline personality disorder with recent suicidal and/or non-suicidal self-injury: An effectiveness study in an Australian public mental health service.

OBJECTIVES: Borderline personality disorder is a complex mental disorder that is associated with a high degree of suffering for the individual. Dialectical behaviour therapy has been studied in the largest number of controlled trials for treatment of individuals with borderline personality disorder. The conversational model is a psychodynamic treatment also developed specifically for treatment of borderline personality disorder. We report on the outcomes of a randomised trial comparing dialectical behaviour therapy and conversational model for treatment of borderline personality disorder in a routine clinical setting. METHOD: Participants had a diagnosis of borderline personality disorder and a minimum of three suicidal and/or non-suicidal self-injurious episodes in the previous 12 months. Consenting individuals were randomised to either dialectical behaviour therapy or conversational model and contracted for 14 months of treatment (n = 162 commenced therapy). Dialectical behaviour therapy involved participants attending weekly individual therapy, weekly group skills training and having access to after-hours phone coaching. Conversational model involved twice weekly individual therapy. Assessments occurred at baseline, mid-treatment (7 months) and post-treatment (14 months). Assessments were conducted by a research assistant blind to treatment condition. Primary outcomes were change in suicidal and non-suicidal self-injurious episodes and severity of depression. We hypothesised that dialectical behaviour therapy would be more effective in reducing suicidal and non-suicidal self-injurious behaviour and that conversational model would be more effective in reducing depression. RESULTS: Both treatments showed significant improvement over time across the 14 months duration of therapy in suicidal and non-suicidal self-injury and depression scores. There were no significant differences between treatment models in reduction of suicidal and non-suicidal self-injury. However, dialectical behaviour therapy was associated with significantly greater reductions in depression scores compared to conversational model. CONCLUSION: This research adds to the accumulating body of knowledge of psychotherapeutic treatment of borderline personality disorder and supports the use of both dialectical behaviour therapy and conversational model as effective treatments in routine clinical settings, with some additional benefits for dialectical behaviour therapy for persons with co-morbid depression.

Comparison of suicide risk and other outcomes among boys and girls who self-harm.

Little is known about sex differences in outcomes of self-harm, and there are inconclusive results concerning the association between sex, self-harm, and suicide attempts. The aim of this study was to explore sex differences in outcomes of self-harm in adolescence. In this cohort study, all individuals (0-17 years) enrolled at the child- and adolescent mental health services (CAMHS) in Stockholm between 2001 and 2015 (N = 110,072) were followed in national registers from their last contact with the CAMHS, until end of 2015. Exposure was self-harm as reason for contact, outcome measures were: alcohol-/substance use disorder, psychiatric hospitalization, non-violent or violent crime, and suicide. Differences in outcomes rates between exposed versus unexposed males, and exposed versus unexposed females, were examined using Cox regressions, expressed as hazard ratios (HR) with 95% confidence intervals (CI). Median follow-up time was 5.8 years (Q1: 2.3 years; Q3: 9.7 years). Self-harm was documented in 2.2% (N = 1241) males and 8.7% (4716) females. Exposed individuals had higher HR for all outcomes as compared with unexposed individuals of their own sex. Exposed females had more pronounced risk for drug use disorder (HR 11.2; 95% CI 9.9-12.7) compared with exposed males (HR 6.5, 95% 5.2-8.0). Both males and females who had engaged in self-harm had elevated risks for future suicide. Adjusting for socio-economic status and age at start of follow-up only marginally affected the associations. Females and males with self-harm had similarly elevated risk for suicide, and self-harm was also an important risk marker for other adverse outcomes within both sexes.

Development, behaviour and autism in individuals with SMC1A variants.

INTRODUCTION: Development and behaviour in Cornelia de Lange Syndrome (CdLS), including autism characteristics, have been described infrequently stratified to genetic cause and only a few studies have considered behavioural characteristics in relation to developmental level. Here, we describe the behavioural phenotype in individuals with CdLS with SMC1A variants. METHODS: We performed an international, interdisciplinary study on 51 individuals with SMC1A variants. Results of questionnaire studies are compared to those in individuals with Down Syndrome and with Autism Spectrum Disorder. Results on cognition and self-injurious behaviour (SIB) are compared to those in individuals with CdLS caused by NIPBL variants. For Dutch participants with SMC1A variants we performed direct in-person assessments of cognition, autism, and added an interview and questionnaire on adaptive behaviour and sensory processing. RESULTS: Individuals with SMC1A variants show a higher cognitive level and less SIB than individuals with NIPBL variants. Individuals with SMC1A variants without classic CdLS phenotype but with a Rett-like phenotype show more severe intellectual disability and more SIB compared to those with a CdLS phenotype. Autism is less present if outcomes in direct in-person assessments are evaluated taking developmental level into account compared to results based on a questionnaire. CONCLUSIONS: Behaviour in individuals with CdLS should be evaluated taking genetic cause into account. Detailed interdisciplinary approaches are of clinical importance to inform tailored care and may eventually improve quality of life of patients and families.

Talk About Self-Harm (TASH): participatory action research with young people, GPs and practice nurses to explore how the experiences of young people who self-harm could be improved in GP surgeries.

BACKGROUND: The incidence of self-harm in young people in primary care is increasing dramatically, and many young people who self-harm visit their GP surgery as a first point of contact for help. OBJECTIVE: To explore with young people, GPs and practice nurses (PNs): (i) why young people present with self-harm to primary care and (ii) whether young people, GPs and PNs can take steps to have more helpful consultations about self-harm in GP surgeries that include self-help materials developed by young people being used to support such consultations to take place. METHODS: Participatory action research with GPs, PNs and young people employed mixed methods to collect statistical and narrative data. Statistics from 285 young people's medical records were captured, including more detailed analyses of a random sample of 75 of these records. A series of 24 focus groups with a total of 45 GPs, PNs and young people, with an average number of eight participants in each group, was conducted. Statistical data were subject to descriptive and inferential analyses, and thematic analysis was applied to the transcripts from the focus groups. RESULTS AND CONCLUSION: The type of self-harm young people presented with influenced whether they would see a GP or PN. While self-help materials were welcomed and deemed helpful, young people, GPs and PNs were ambivalent about using these in short consultations where time was an overriding constraint. More research is needed on the feasibility of adopting self-help assisted interventions in GP surgeries.

A retrospective cohort study comparing non-fatal self-harm emergency department visits between Canadian veterans living in Ontario and matched civilians.

This was a retrospective cohort study linking provincial administrative databases to compare rates of non-fatal self-harm between CAF and RCMP veterans living in Ontario and age-matched civilians. This study included male veterans who registered for provincial health insurance between 2002 and 2013. A civilian comparator group was matched 4:1 on age and sex. Self-harm emergency department (ED) visits were identified from provincial ED admission records until death or December 31, 2015. Multivariable Poisson regression compared the risk of self-harm. Analyses adjusted for age, geography, income, rurality, and major physical and mental comorbidities. In total, 9514 male veterans and 38,042 age- and sex-matched civilians were included. Overall, 0.55% of veterans had at least one non-fatal self-harm ED visit, compared with 0.81% of civilians. The rate of ED self-harm visits was 40% lower in the veteran population, compared to the civilian population (RR = 0.60; 95% CI = 0.41-0.87). In both groups, psychosocial and physical comorbidities, and death by suicide were more common in those who self-harmed than those who did not. A better understanding of why veterans have a lower rate of self-harm emergency department visits and how it is related to the number of completed suicides is an important area for future consideration.

Association between psychotic experiences and non-accidental self-injury: results from a nationally representative survey of adolescents.

PURPOSE: The association between psychotic experiences (PEs) and non-accidental self-injury (NASI; including self-harm and suicide attempts) is well established, although variables influencing this relationship have not been comprehensively examined. This study aimed to investigate (1) the cross-sectional PE-NASI association before and after adjustment for confounders, and (2) the individual contribution of each confounding and potentially mediating variable to the association. METHODS: A random sample of Australian adolescents aged 14-17 years (n = 1998) completed self-report questions regarding any self-harm, suicidality or PEs experienced in the past 12 months in 2013-2014 as part of the Young Minds Matter Survey, a national household survey. We conducted logistic regression analyses to investigate the association between NASI and PEs, after controlling for confounders (sociodemographics, substance use, and parental mental illness) as well as the influence of potential mediators (major depression, bullying, psychological distress, sleep, self-esteem, disordered eating behaviour, social isolation, and intervention factors). RESULTS: Except for special messages, all PE subtypes (auditory and visual hallucinatory experiences [HEs], and two of the three delusional experiences [DEs]) were associated with NASI after adjustment for confounders (OR range: 2.60-5.21). Depression and psychological distress significantly influenced all PE-NASI associations, where depression appeared to fully explain the DE-NASI association, and partially attenuate the HE-NASI association. Variables such as parental mental illness, disordered eating behaviour, and social isolation had negligible effects in nearly all self-harm and attempted suicide models. CONCLUSIONS: Adolescents reporting any PE in the past 12 months reported increased likelihood of NASI in the same time period and, auditory HEs in particular, were strongly and independently associated with self-harm and suicide attempts. These results highlight the importance of PEs as indicators of risk of self-injurious behaviour among Australian youth.

Behaviour problems in people with intellectual disabilities: validation of the French version of the Behaviour Problems Inventory - Short Form.

OBJECTIVE: The risk for the development of severe behaviour problems by individuals with intellectual disability (ID) is a well-known concern. However, there are currently no reliable instruments for assessing these behaviours in French. The Behaviour Problems Inventory - Short Form (BPI-S) assesses these three types of behaviour in people with ID: self-injurious behaviour (eight items), aggressive/destructive behaviours (10 items) and stereotypic behaviours (12 items). The purpose of this study was to conduct a psychometric study of a French version of the BPI-S. METHOD: Data were collected on 305 children, adolescents and young adults with ID 50 care workers in seven specialised institutions in France as informants. We examined the scale's factorial structure (using confirmatory factor analysis), internal consistency and inter-rater reliability. We also established preliminary French norms. RESULTS: Our results show that the French BPI-S has a factorial structure similar to that of the English version. It has good internal consistency. The internal consistency of the frequency ratings was 0.91 and 0.62 for the severity ratings. The BPI-S has a good inter-rater reliability with acceptable coefficients for the frequency ratings (Self Injurious Behaviour (SIB) = 0.81; Aggressive-Destructive behaviour = 0.66; Stereotyped behaviours = 0.75) and for the severity ratings (SIB = 0.92; Aggressive-Destructive behaviour = 0.54). The data also show that the frequency and severity of behaviours differ based on the level of ID. CONCLUSIONS: The French version of the BPI-S has good psychometric properties for assessing problem behaviours in children, adolescents and young adults. This scale can be used for research and clinical evaluation of disorders associated with ID.
