Validation of a French questionnaire assessing knowledge of suicide.

OBJECTIVES: The objective of this study was to develop and validate the Knowledge of Suicide Scale (KSS), elaborated to assess adherence to myths about suicide. METHODS: The KSS is a self-questionnaire including 22 statements relating to myths about suicide for which the respondent is asked to rate his degree of adherence on a scale ranging from 0 ("strongly disagree") to 10 ("completely agree"). Using the script concordance test scoring method, the respondents' scores were compared with those of experts to obtain, for each item, a score between 0 (maximum deviation with the experts) and 1 (minimum deviation with the experts). One thousand and thirty-five individuals (222 psychiatric interns, 332 medical interns in the first semester excluding psychiatry and 481 journalism students) were included. RESULTS: According to the exploratory factor analysis, the KSS is a two-dimensional scale: the first subscale includes 15 items and the second seven items. The tool showed excellent face validity, correct convergent and divergent validities (multi-method multi-feature analyzes), and good internal consistency (Cronbach's alpha coefficient between 0.66 and 0.83 for scales and subscales). The KSS is moderately and negatively correlated with the Stigma of Suicide Scale (r=-0.3). It significantly discriminates groups with different expected levels of knowledge regarding suicide (P<0.001). CONCLUSIONS: The KSS demonstrated good psychometric properties to measure adherence to myths about suicide. This tool could be useful in assessing the effectiveness of suicide prevention literacy improvement programs.

Being pro-active in meeting the needs of suicide-bereaved survivors: results from a systematic audit in Montréal.

BACKGROUND: Suicide is a major public health concern. In 2017, the suicide rate in Canada was 11 per 100,000 inhabitants. According to literature, 1 in 5 people have experienced a death by suicide during their lifetime. The aim of this study was to describe the met and unmet needs of suicide-bereaved survivors and to provide postvention recommendations. METHODS: Further to an exploratory mixed-method audit of 39 suicides that occurred in Montreal (Canada) in 2016, suicide-bereaved survivors (n = 29) participated in semi-structured interviews and completed instruments to discuss and assess potential pathological grief, depression (PHQ-9), and anxiety (GAD-7), as well as health and social services utilization. A panel then reviewed each case and provided recommendations. The mean age of participants was 57.7 years and 23 were women. RESULTS: Although help was offered initially, in most cases by a health professional or service provider (16/29), 22 survivors would have liked to be contacted by telephone in the first 2 months post suicide. Four categories of individual unmet needs (medical/pharmacological, information, support, and outreach) and one collective unmet need (suicide pre/postvention training and delivery) emerged. CONCLUSIONS: Although Quebec provincial services have been developed and offered to suicide-bereaved survivors in the past decade, many dwindled over time and none has been applied systematically. Recommendations for different stakeholders (Ministry of Health and Social Services, coroners, NGOs, and representatives of suicide-bereaved survivors) outlined in this study could be an interesting first step to help develop a suicide pre/postvention strategy.

Survey evidence of the decline in child abuse in younger Canadian cohorts.

Physical and sexual abuse in childhood is a worldwide phenomenon with potentially dramatic consequences of both a psychological and physical nature. Measures of primary prevention have been developed in some countries. In the USA, child protection services reports and research surveys indicate that child sexual abuse has been on the decline in recent decades. Results are less clear for physical and overall abuse. The aim of this study was to describe how childhood abuse has changed over the years in Canada through an analysis of the 2012 Canadian Community Health Survey: Mental Health Edition data. The sample comprised 22,775 respondents ages 20 and over who completed a child abuse questionnaire. Respondents born from 1983 to 1992 reported significantly less overall abuse, physical abuse, and sexual abuse than did older generations, with the exception of people born in 1942 or earlier. The decrease was observed among men and women and across all the regions of Canada.Conclusion: The results are encouraging in that they may have an impact on life expectancy, severity of various chronic disorders, and suicide in the population. They also support policies that have focused on improving the childhood environment in the 1990s. Results also underline the importance of using different kinds of data sources for evaluating child abuse. What is Known: • Physical and sexual abuse in childhood has been associated with lower life expectancy in connection with an array of chronic diseases, including mental disorders, and with suicide. • Measures of primary prevention have been developed in some countries, such as the USA and Canada. What is New: • Canadians born from 1983 to 1992 report significantly less overall abuse, physical abuse, and sexual abuse than older generations do. • These encouraging results support policies implemented in the 1990s focused on improving the childhood environment.

[Childhood Maltreatment and Mental Health Problems in Adulthood: A National Study of Women in Quebec]. / Mauvais traitements subis dans l'enfance et problèmes de santé mentale à l'âge adulte : une étude nationale conduite auprès des Québécoises.

Objective The study aims to estimate the specific contribution of various forms of child maltreatment on the mental health among a Quebeckers' women representative sample. Method A telephone survey was conducted with a representative sample of 1001 women from the province of Quebec (Canada). Different demographic variables, all four child maltreatment forms (sexual, physical, psychological and neglect) and intimate partner violence experienced in the last 12 months were evaluated to explore their links with depression and post-traumatic stress symptoms of the participants at the time of the investigation.Results Domestic violence during the last 12 months as well as negligence and physical violence during childhood are associated with the presence of clinical intensity post-traumatic symptoms. Youngest age, sexual and psychological violence during childhood are associated with the presence of depression.Conclusion Those results underlie the importance to consider different forms of maltreatment during childhood and their co-occurrence in the evaluation and the intervention in mental health with adult women.

Implementing Suicide Prevention Programs: Costs and Potential Life Years Saved in Canada.

BACKGROUND: Little is known about the costs and effects of suicide prevention programs at the population level. AIMS OF THE STUDY: We aimed to determine (i) the costs associated with a suicide death and using prospective values (ii) the costs and effects of transferring, into a Canadian context, the results of the European Nuremberg Alliance against Depression (NAD) trial with the addition of 4 community-based suicide prevention strategies. These included the training of family physicians in the detection and treatment of depression, population campaigns aimed at increasing awareness about depression, the training of community leaders among first responders and follow-up of individuals who attempted suicide. METHODS: This study includes a prospective value implementation study design. Using published data and information from interviews with Canadian decision makers, we assessed the costs of a suicide death in the province of Quebec and the costs of potentially implementing the NAD multi-modal suicide prevention programs, and the incremental cost-effectiveness ratio (ICER), from a health care system and societal perspective, associated with the NAD program while considering the friction cost method (FCM) and human capital approach (HCA) (discounted at 3%.) The costs considered included those incurred for the suicide prevention program and direct medical and non-medical costs as well as those related to a police investigation and funeral costs. Indirect costs associated with loss of productivity and short term disability were also considered. Sensitivity analyses were also carried out. Costs presented were in 2010 dollars. RESULTS: The annual total cost of implementing the suicide prevention programs in Quebec reached CAD23,982,293. The most expensive components of the program included the follow-up of individuals who had attempted suicide and psychotherapy for bereaved individuals. These accounted for 39% and 34% of total costs. The ICER associated with the implementation of the programs reached on average CAD3,979 per life year saved. DISCUSSION: Suicide prevention programs such as the NAD trial are cost-effective and can result in important potential cost-savings due to averted suicide deaths and reduced life years lost. IMPLICATIONS FOR HEALTH CARE PROVISION AND USE: Implementation of suicide prevention programs at the population level in Canada is cost-effective. Community mental health programs aimed at increasing awareness and the treatment of depression and better follow-up of high risk individuals for suicide are associated with a minimal per capita investment. These programs can result in important potential cost-savings due to averted suicide deaths and decreased disability due to depression. IMPLICATIONS FOR FURTHER RESEARCH: Additional research should focus on whether the outcomes of multi-modal suicide programs are specific or synergistic and most effective for which population subgroups. This may help inform how best to invest resources for the highest return.

Developmental model of suicide trajectories.

BACKGROUND: Most developmental studies on suicide do not take into account individual variations in suicide trajectories. AIMS: Using a life course approach, this study explores developmental models of suicide trajectories. METHOD: Two hundred and fourteen suicides were assessed with mixed methods. Statistical analysis using combined discrete-time survival (DTS) and growth mixture modelling (GMM) generated various trajectories, and path analysis (Mplus) identified exogenous and mediating variables associated with these trajectories. RESULTS: Two groups share common risk factors, and independently of these major risk factors, they have different developmental trajectories: the first group experienced a high burden of adversity and died by suicide in their early 20s; and the second group experienced a somewhat moderate or low burden of adversity before they took their own life. Structural equation modelling identified variables specific to the early suicide trajectory: conduct and behavioural difficulties, social isolation/conflicts mediated by school-related difficulties, the end of a love relationship, and previous suicide attempts. CONCLUSIONS: Psychosocial adversity between 10 and 20 years of age may warrant key periods of intervention.

Emergency department care experience of suicidal patients: A qualitative analysis of patients' perspectives.

INTRODUCTION: Individuals experiencing suicidal ideation or behavior frequently seek assistance at the emergency department (ED), yet the care they receive does not consistently align with their needs. This study explores the ED care experience of suicidal patients from their own perspective and offers recommendations to improve ED care for this population. METHOD: This qualitative study uses a descriptive interpretative design. Semi-structured interviews were conducted with 7 individuals who sought care in an ED due to suicidal ideation or behavior. Transcripts were analyzed using thematic analysis. FINDINGS: Participants' experiences were marked by an unsuited physical environment described as uncomfortable, noisy, and depressing. The organization of care was perceived as inadequate as patients complained about limited front-line access to mental health expertise, long waiting times, overworked staff, and inequities between patients with physical injuries and those with mental health concerns. Participants reported feelings of being trapped, left on their own and mistreated during their ED stay. Most found their care experience unhelpful or distressing, leaving them reluctant to reconsult. Specific recommendations based on patients' testimonials and literature are provided to enhance the ED care experience of suicidal patients. CONCLUSION: This study highlights several areas for improvement of the ED care experience of suicidal patients. Changes in current practices are needed to offer suicidal patients the satisfying care experience they deserve.

Identifying suicidal risk factors in the French Overseas Territories with multimethod psychological autopsy (AUTOPSOM): a mixed-methods study protocol.

INTRODUCTION: Understanding suicide in more isolated territories is a challenge because of the entanglement of cultural identity with historical, geographical and sociocultural specificities. This knowledge is a necessary precondition for the implementation of targeted prevention strategies in regions such as the French overseas territories (FOT), where data concerning suicidal risk factors is still incomplete. We aim to untangle sociocultural and clinical suicide risk factors by integrating a novel anthropological and psycholinguistic approach into the psychological autopsy method. This article describes the protocol of the clinical study 'Contribution of Psychological Autopsy to the Understanding of Suicidal Behaviours in Overseas France' (AUTOPSOM study), designed to identify common or new specific suicide risk factors in four FOT. METHODS AND ANALYSIS: A multicentre epidemiological study will be carried out in four FOTs (French Polynesia, Martinique, La Reunion and French Guiana) and at a comparison site in mainland France (La Somme). The methodology will be based on a mixed-methods (quantitative and qualitative) approach using a psychological autopsy to collect clinical data and life events in the deceased's life. We implemented an exploratory multimethod strategy that combines a succession of epidemiological, anthropological, psycholinguistic and psychological methods with a semiautomated analysis of the discourse of relatives bereaved by suicide. ETHICS AND DISSEMINATION: The study protocol (first version) was approved by the French Ethics Committee (CPP OUEST II, approval #22.04267.000122) and the Ethics Committee of French Polynesia (JOPF of 5 April 2022; CEPF opinion n°91 of 29 March 2022). The overall results and the perspectives established at the end of the study will be communicated to the bereaved relatives according to their will and serve for local suicide prevention purposes. TRIAL REGISTRATION NUMBER: NCT05773898.

[Are mental health disorders' characteristics such as presence and severity related to the nature of a crisis, its dangerousness and the types of services offered?]. / La présence et la gravité des troubles de santé mentale sont-elles liées à la nature de la crise, à la dangerosité et aux services de crise offerts ?

UNLABELLED: The mandate of crisis centres varies substantially from one country to the next according to the government policies in effect. In the United States, crisis centres were developed based on Caplan's theory, which defines crisis as a psychosocial disorganization following a life event that is resolved with a return to balance. This approach aims at preventing the onset of mental health disorders through short-term intervention. It is different in Quebec, where crisis centres were developed in a deinstitutionalization context and ought to constitute an alternative to hospitalisation. Such mandate of Quebec crisis centres is not necessarily of the preventive nature associated with Caplan's theory and it has led to services having to be adapted to a heterogeneous clientele that may or may not suffer from mental health problems. It has implications related to the crisis characteristics such as its nature, intensity, and dangerosity, as well as implications regarding the organization of crisis centre services, which have been the object of few studies so far. OBJECTIVE: The present study aims at distinguishing clinical profiles of crisis centre callers according to the presence or absence of a mental health disorder and its nature, that is severe and persistent (psychotic or bipolar disorder) or not (mood, anxiety or personality disorder). In order to do so, participants are compared on the characteristics of the crisis and the services they received. METHOD: In this descriptive study, the files of 1170 new assistance applicants are retrospectively analyzed based on a predetermined grid that was used to collect data according to the main clinical characteristics of persons in distress, as recognized in the literature. The subgroup of persons presenting a psychotic or bipolar disorder was examined separately from the one comprising persons with an anxiety, mood or personality disorder because of its clinical complexity, which generally requires intensive, multidisciplinary follow-up. RESULTS: Among the new applicants, 48% had a mental health disorder and, of these, 9% reported a serious mental health disorder, that is, a psychotic or bipolar disorder. The results indicate that having an anxiety-, mood- or personality-type disorder is associated with a higher probability of reporting stressful interpersonal-type events, a more intense crisis, as well as a greater risk of auto-aggressive behaviours. Meanwhile, persons with a psychotic or bipolar disorder are more frequently provided with accommodations and more likely to receive intensive and support services, such as emergency interventions or the use of the Act respecting the protection of persons whose mental state presents a danger to themselves or others (P-38). CONCLUSIONS: This descriptive portrait of the crisis centre clientele contributes to the reflection on differential intervention with persons in a crisis situation. It appears important to take an interest in the presence and type of mental health disorders of crisis centre callers, since these characteristics help to better foresee not only the nature and intensity of the crisis but also the type of services required. However, Quebec crisis centres have to respond to the needs of a heterogeneous clientele without having access to a typology and a theoretical model that consider this clinical diversity. Other studies should be conducted to validate, on the one hand, a crisis typology that would make it easier for caseworkers to collect data for evaluation purposes and, on the other hand, a differential intervention model.

[Alcohol and drug consumption in students exposed to the Dawson College shooting: a gender-based analysis]. / La consommation d'alcool et de drogue des étudiants suite à la fusillade de Dawson : une analyse différenciée selon le sexe.

OBJECTIVE: To study alcohol and drug addiction incidence in students exposed to the Dawson College shooting within the 18 months following the event, to identify the precursors of a psychoactive substance addiction development while considering the severity of event exposure, and to examine whether alcohol use, 18 months after the event, is related to any of the various posttraumatic stress disorder (PTSD) symptom groups. METHOD: The population of this study was comprised of all the Dawson College students at the time of the event. Analyses were conducted with 854 students enrolled in the college at the time of the shooting. RESULTS: Five per cent of women and 7% of men showed, for the first time in their life, a problem with substance addiction following the shooting. In men, young age, lifetime suicidal ideation, and having seen the killer during the shooting are the main precursors of incident accident cases. None of the studied precursors were significant in women. Men and women were also different in terms of PTSD symptoms predicting alcohol use 18 months after the shooting. CONCLUSION: The study highlights the importance of considering a person's sex when studying their psychoactive substance use following a trauma.

[The contribution of research in psychology in the complex comprehension of the etiology of suicide]. / L'apport de la recherche en psychologie dans la compréhension complexe de l'étiologie du suicide.

If certain risk factors are known to increase suicidal behaviors, the question is to determine the differential weight of these various risk factors, on which individuals, in which context and in what period of their lives? We have put to test a model that explains different life trajectories leading to suicide. This research allows to surpass a correlation model of identification of risk factors and to target four distinct sub-groups of individuals for whom the developmental history seems quite different. It is clear that suicide is a complex, multidimensional and multilevel issue. Being at the crossroads of many scientific disciplines, psychology may help integrate and connect knowledge with other disciplines in order to clarify the contexts that affect suicidal individuals differently. This knowledge may help in identifying specific prevention interventions that could modify this chain of events leading ultimately to suicide.

Comparing Childhood Characteristics of Adopted and Non-adopted Individuals Deceased by Suicide.

Objective: Across the globe more than 35,000 children a year are adopted by non-relatives, and some studies suggest that adopted individuals may be more vulnerable to developing mental disorders. To map the differences in suicide risk factors in adopted and non-adopted individuals, this study will compare the development of mental disorders as well as life events occurring before the age of 18 for both adopted and non-adopted individuals deceased by suicide. Methods: This study included 13 adopted and 26 non-adopted individuals deceased by suicide as well as 26 non-adopted living control individuals. Cases were taken from a data bank created over the last decade by researchers of [our institution] comprising a mixture of 700 suicide cases and living control individuals aged from 14 to 84. Adopted and non-adopted individuals deceased by suicide; adopted individuals deceased by suicide and non-adopted living control individuals were each compared on Axis I and II disorders, early life events, and burdens of adversity. Results: Results show significant differences, with a higher rate of Attention Deficit Hyperactivity Disorder, mental health comorbidity and Cluster C personality disorders among adopted individuals. Furthermore, adopted individuals have higher adversity scores prior to the age of 15. Conclusion: This study underlines the fact that adoptive families need to be supported throughout adoption. Health care professionals need specialized training on this matter, and the psychological challenges adopted individuals face need to be treated at the earliest juncture.

Social isolation and suicide risk: Literature review and perspectives.

BACKGROUND: Suicide is a major public health problem and a cause of premature mortality. With a view to prevention, a great deal of research has been devoted to the determinants of suicide, focusing mostly on individual risk factors, particularly depression. In addition to causes intrinsic to the individual, the social environment has also been widely studied, particularly social isolation. This paper examines the social dimension of suicide etiology through a review of the literature on the relationship between suicide and social isolation. METHODS: Medline searches via PubMed and PsycINFO were conducted. The keywords were "suicid*" AND "isolation." RESULTS: Of the 2,684 articles initially retrieved, 46 were included in the review. CONCLUSIONS: Supported by proven theoretical foundations, mainly those developed by E. Durkheim and T. Joiner, a large majority of the articles included endorse the idea of a causal relationship between social isolation and suicide, and conversely, a protective effect of social support against suicide. Moreover, the association between suicide and social isolation is subject to variations related to age, gender, psychopathology, and specific circumstances. The social etiology of suicide has implications for intervention and future research.

Adversity Over the Life Course: A Comparison Between Women and Men Who Died by Suicide.

Purpose: This study sets out to compare the presence of life events across different domains throughout the life course which may contribute to the burden of adversity experienced differently among men and women who died by suicide. Method: In a sample of 303 individuals (213 men and 90 women), data was derived from extensive clinical interviews conducted with informants. Models allowed the identification of patterns of life trajectories. Results: Overall, the burden of adversity was similar across the life course except for the 5-9, 25-29, and 30-34 age ranges, where a significant difference appeared between genders [t-test = 2.13 (p < 0.05), 2.16 (p < 0.05) and 3.08 (p < 0.005), respectively] that seems to disadvantage women. The early adversities of violence and neglect, between 0 and 19 years old, are important for both groups. During the life course, women were more exposed to interpersonal adverse events such as being victims of negligence and violence, relational difficulties or abuse from their spouse, as well as tension with their own children. Men encountered more academic difficulties, legal entanglements and financial difficulties, and were more than three times more likely to develop an alcohol/drug abuse problem than women. Conclusions: The data suggests some gender differences in exposure to longstanding and severe life problems contributing to suicide vulnerability. For women, the continuing burden emerges from chronic interpersonal adversities, whereas, for men, the adverse events are to a larger degree socially exposed, compounded with alcohol misuse. The adversities, especially those of a public or social nature, may be witnessed by others, which should favor the detection of vulnerability over the life course, and psychosocial or mental health services should be offered and provided earlier during the life course. Yet more men die by suicide than women. Resiliency and protective factors may benefit women to a greater degree. Future research should tackle the challenge of investigating these important elements. Meanwhile, from a public health perspective, access to psychosocial and mental health services and social acceptability of seeking services should be part of an ongoing effort in all institutional structures as a way of decreasing downstream mental health problems and vulnerability to suicide.

Everyday ethics of suicide care: Survey of mental health care providers' perspectives and support needs.

Suicide occurs in people of all ages and backgrounds, which negatively affects families, communities, and the health care providers (HCPs) who care for them. The objective of this study was to better understand HCPs' perspectives of everyday ethical issues related to caring for suicidal patients, and their perceived needs for training and/or support to address these issues. We conducted a mixed methods survey among HCPs working in mental health in Québec, Canada. Survey questions addressed their perspectives and experiences of everyday ethical challenges they encounter in their practice with people who are suicidal, and their perceived needs for training and/or support therein. 477 HCPs completed the survey. Most participants mentioned encountering ethical issues when caring for people who are suicidal. The challenges HCPs encounter in their practice with people who are suicidal are numerous, including issues related to maintaining privacy, confidentiality, freedom and the therapeutic relationship. The lack of time, resources and professional support to address these issues was emphasized. Most HCPs reported that the training or education they have received does not allow them to address everyday ethical issues related to suicide care. In sum, there is a clear reported need for better training and support for HCPs who are offering care to people who are suicidal in relation to everyday ethical issues they encounter. Implications for practice include providing greater access to training, including access to specialists in ethics to address specific issues. This additional support could alleviate morally distressing situations for HCPs.

Suicides in Nunavik: a life course study.

This study reports results of a life course study conducted with Inuit in Nunavik to obtain information on the life adversities and cumulative burden of adversity for three groups: those who died by suicide, those who attempted suicide, and those who experienced suicidal ideation but never attempted. The study involved different levels of collaboration between health authorities, front-line health workers and the research team. Results indicate that substance misuse and relational difficulties are most associated with the burden of adversity for those people who died by suicide, while bullying is most associated with the burden of adversity for those people who have made suicide attempts and those who have never made a suicide attempt. Specifically targeting parent-child relations, substance misuse, and bullying may be an important upstream strategy for reducing future suicidality in Nunavik.

Suicide in French Polynesia: a retrospective analysis based on medicolegal documents and interview with family.

OBJECTIVE: To analyse the epidemiological data on suicide in French Polynesia (FP). METHODS: Data on suicides were collected from the Public Health Direction, Judicial Police Investigations Court of Justice records, the Centre d'Opérations et de Renseignements de la Gendarmerie, patient records for those hospitalized in psychiatry and from psychological autopsies. RESULTS: The dataset consisted of 316 suicide cases in FP over 25 years (1992-2016). In FP, suicide was more frequent in men (sex ratio 3.2:1), young people (mean age, 34.4 years) and individuals with previously diagnosed psychiatric disorders (100 of 316; 31.6%) The most common method of suicide was hanging (276 of 316; 87.3%). A history of previous suicide attempts was found in 25 of 56 (44.6%) of suicide cases, when documented. The most common potential triggering factors for suicide were emotional problems. The suicide rates have remained stable during 1992-2016 (mean 10.6/100 000 inhabitants per year), with periods of economic crises increasing suicide rates. CONCLUSIONS: These results provide valuable information to enable the effective targeting of suicide prevention strategies toward those at high risk. Economic crises had larger impacts in the French overseas territories than mainland France. Given the unprecedented economic impact of the Covid-19 pandemic in FP, there is an urgent need to implement suicide epidemiological surveillance and prevention programmes.

Are school difficulties an early sign for mental disorder diagnosis and suicide prevention? A comparative study of individuals who died by suicide and control group.

BACKGROUND: Suicide is the third leading cause of death worldwide among youth aged 10- to 19, and mental disorders are often associated in the etiology of suicidal behavior. Mental disorders are often under-diagnosed and under-treated in young people, a situation likely to increase the severity of the disorder and suicide risk. Presence of school difficulties may, in some cases, be a consequence of mental disorder, and theses difficulties are observable. Therefore, early detection and early intervention of school difficulties may alleviate the development of mental disorders and suicide vulnerability. The aim of this study is to understand the link between school difficulties and suicide risk. METHODS: We used the data bank gathered by the McGill Group on Suicide Studies over the past two decades through interviews with the relatives of individuals who died by suicide and with individuals from the community as a control group. We included data on common sociodemographic characteristics, life events and mental health characteristics identified before age 18, among individuals who died before the age of 35 or were interviewed before the age of 35. We identified 200 individuals who died by suicide and 97 living controls. We compared groups according to gender and characteristics. RESULTS: Within the total sample, 74% were male, 13% had met with academic failure, 18% had engaged in inappropriate behavior at school, and 18% presented combined school difficulties. Combined school difficulties (academic failure and inappropriate behavior) for both sexes and academic failure alone for males were associated with higher suicide risk before the age of 35. School difficulties generally began in early childhood and were linked to mental disorders/difficulties and substance abuse before age 18. CONCLUSIONS: This study underlines the importance for parents, teachers, and educators to identify children with school difficulties-academic failure and behavioral difficulties at school-as early as possible in order to be able to propose adapted interventions. Early identification and proper diagnosis may prevent chronicity of some disorders, accumulation of adverse events, and even suicide.
