For two people who made me a better person.
Dr Clare Cassidy (1968–2008)
I continue to be inspired by Clare’s memory daily. An amazing friend and colleague.
“But then with autumn upon us, so breezy and cruel,Clare left us in Paris, heartbroken and cool.
But we remember Clare’s grace, her beauty, her light;Her kindness, her smile and sadness, its might.”
(RO’C, 2008)
Professor Noel Sheehy (1955–2011)
One day in the summer of 1994 Noel asked me whether I might be interested in undertaking a PhD on suicide—without hesitation I jumped at the chance. Without him, I would never have embarked on a career in suicide research.
He took a chance on me. For this (and many other things besides) I will always be grateful. So kind and generous.

The International Handbook of Suicide Prevention, Second Edition. Edited by Rory C. O’Connor and Jane Pirkis. © 2016 John Wiley & Sons, Ltd. Published 2016 by John Wiley & Sons, Ltd.
IntroductionRory C. O’Connor and Jane Pirkis
Since the publication of the first edition of the International Handbook of Suicide Prevention in 2011 (O’Connor, Platt, & Gordon, 2011), Preventing Suicide: A Global Imperative has been published by the World Health Organization (World Health Organization [WHO], 2014). This landmark publication, the first ever world suicide prevention report, highlighted the scale of the task of suicide prevention. At least 804,000 people take their own lives each year across the globe, which translates into a death every 40 seconds. The report also touches on many of the issues that we examine in detail herein, including the epidemiology of suicide and how best to intervene to prevent it. We are delighted that many of those who contributed to the WHO report have authored chapters for the second edition of this Handbook.
There are a number of changes in this edition of the Handbook. First, there is a change in editorship. Rory C. O’Connor has been joined by Jane Pirkis from University of Melbourne as coeditor, and Jane takes the place of Stephen Platt and Jacki Gordon, who were coeditors of the first edition. Second, we have expanded the Handbook; in terms of chapters, it is now 20% longer, which has allowed us to include more hot topics in suicide research and prevention. Third, given that the majority of the world’s suicides occur in Asia and low‐ and middle‐income countries, additional chapters have been dedicated to better understand suicide across different countries and cultures. Fourth, the majority of chapters end with a section describing up to 10 key resources. These resources include a selection of journal articles, books, reports, or online resources that the authors believe the reader would benefit from reading.
As in the first edition of the Handbook, we have tried to understand why people attempt suicide and what can be done to reduce suicide by harnessing the expertise of more than 110 suicidologists from across the world. The Handbook offers kaleidoscopic views on the complex multitude of factors that may explain suicidal behavior and the array of approaches to suicide prevention. It should appeal to anyone with an interest in trying to comprehend suicide and, ultimately, prevent it. To this end, one of the guiding principles of this volume is to improve our understanding of the r elationship between attempted suicide and deaths by suicide. A more comprehensive understanding of this relationship is important not only for theoretical and conceptual reasons but also because secondary prevention interventions are frequently directed at those who attempt suicide. Any national or international suicide prevention strategy, to be effective, must be able to engage those who have attempted suicide.
2 Rory C. O’Connor and Jane Pirkis
Although this may seem self‐evident, it is crucial, given the universal recognition that maintaining patients who have attempted suicide in treatment is fraught with difficulties. Further, it is sobering to note that the best predictor of future suicidal behavior (and suicide) is past suicidal behavior. Therefore, if we can intervene with those who have previously tried to take their own lives, we should be able to prevent at least some of the future deaths by suicide. Consequently, nonfatal suicidal behavior and suicide receive equal attention in this Handbook. As suicide attempt and self‐harm are often used interchangeably in the research literature (also see the following text), where we use the term suicide attempt/suicidal behavior in this Introduction, we are referring to self‐injurious behavior with evidence of suicidal intent. Self‐harm is used to describe all self‐harming behaviors where suicidal intent is not explicitly ascertained.
The overarching aim of this Handbook is to bring together the different exponents of suicide research and prevention irrespective of country of origin or professional background, because only through learning and working together internationally and across disciplines will we rise to the challenge of reducing suicidal behavior in every country. Suicidology, defined as the science of suicide and suicide prevention (Maris, 1993), is little over 55 years old, and embraces researchers, practitioners, and policy planners whose disciplinary backgrounds include psychology, psychiatry, epidemiology, sociology, social work, health economics, nursing, emergency medicine, ethics, law, and public health. This heterogeneity is a major strength, as the whole (i.e., the discipline of suicidology) is much greater than the sum of its constituent disciplines. We continue to learn from each other’s difficulties and successes, and to exchange a broad range of theoretical and methodological perspectives. However, one of the challenges of working in an interdisciplinary manner is that there are inevitable differences in emphasis, which can lead to difficulties in how we communicate about self‐injurious behavior across countries and professions. Although there have been several efforts to reach consensus on definitions and nomenclature (see Chapter 1 by Silverman), as a discipline we have yet to agree on a common definition of suicidal behavior. This renders the comparison of studies difficult. One study may include a heterogeneous sample of patients, some of whom are reporting suicidal intent and some of whom are not, whereas another may include only individuals who have engaged in potentially lethal suicide attempts, with explicit and high suicidal intent. Despite our best efforts, we are unlikely to achieve an agreed definition of suicidal behavior for some considerable time. Indeed, an inspection of the international literature still yields a myriad of different terms to describe the broad spectrum of self‐injurious thoughts and behaviors (e.g., self‐harm, attempted suicide, suicidal behavior, nonsuicidal self‐injury; see Chapter 1 by Silverman). Consequently, we asked each contributing author to make explicit early in their chapter how they operationalized and defined suicidal behavior therein.
Additional aims of the book are to showcase the state of the science in terms of research, policy, and practice, to share insights and expertise, and to enhance mutual learning. In this Handbook, we present the latest research on determinants of suicidal behaviors and the most promising interventions, treatments, and ways of caring for those at risk. We also describe the challenges of translating research, policy, and practice into saving lives. The extent to which suicidologists meet this latter challenge will determine, in large part, whether or not the universal goal of reducing suicide rates across the globe is attained. In short, this Handbook addresses the key questions of
Introduction 3
why people attempt suicide, what the best interventions are for those at risk, and what the key international challenges are in our pursuit of suicide prevention. In addressing these questions, it is important to recognize that the evidence base is, by and large, limited and that it must be understood in terms of the specific characteristics of a study population or the particular context of an intervention. Encouragingly, though, there have been major advances in our understanding of how best to treat and prevent suicidal behavior since the publication of the first edition.
As before, this edition of the Handbook is organized into three parts. Part I is concerned with the determinants and frameworks that inform our understanding of suicide and attempted suicide. Part II focuses on treatment, intervention, and care, and Part III reviews a range of suicide prevention issues that span research, policy, and practice. Chapters 1 to 3 provide the foundations for many of the subsequent chapters. In Chapter 1, for example, Silverman provides an overview of how the international community defines, classifies, and communicates about self‐injury with and without suicidal intent. As noted earlier, these remain contested issues within the field with much of the recent debate stimulated by the inclusion of nonsuicidal self‐injury and suicidal behavior disorder in DSM 5 as areas requiring further research (e.g., Kapur, Cooper, O’Connor, & Hawton, 2013; Oquendo & Baca‐Garcia, 2014). In Chapter 2, Windfuhr, Steeg, Hunt, and Kapur endeavor to bring together the research literature on the factors associated with suicidal behavior from different disciplines, and in Chapter 3, Arensman, Griffin, and Corcoran consider the specific challenge of predicting repetition of self‐harm. These are followed by four chapters (Chapters 4–7) that summarize the research and clinical literature on the relationship between suicidal behavior and psychiatric illness (depression [Chapter 4 by Rihmer and Dome], schizophrenia and other psychotic disorders [Chapter 5 by Desîlets, Labossière, McGirr, & Turecki), substance user disorders [Chapter 6 by Conner and Ilgen], and personality disorders [Chapter 7 by Paris]). The Handbook also considers the extent to which the treatment of these disorders can reduce suicide and attempted suicide. The risk of suicide in medical conditions is described in Chapter 8 (by Pompili, Forte, Berman, and Lamis).
The neurobiological and neuropsychological substrates that underpin suicidal behavior are considered in Chapters 9 and 10. In Chapter 9, Mann and Currier review the role of the serotonergic and noradrenergic neurotransmitter systems and the hypothalamic–pituitary–adrenal axis. They highlight the importance of studying the interaction between genetic vulnerability and environmental adversity in early life as a means of understanding how the effects of developmental changes in neurobiological systems can persist into adulthood and affect suicide risk. Chapter 10 by van Heeringen and Bijttebier investigates how changes in brain function are mediated by neuropsychological factors to increase the risk of suicide in response to stressors. In a new addition to this edition, the research findings and clinical implications of magnetic resonance imaging (MRI), diffusion tensor imaging, functional MRI (fMRI), positron emission tomography, and single photon emission computed tomography studies in suicide attempters are reviewed in Chapter 11 by Sudol and Oquendo.
The central role of psychology in understanding suicide risk is highlighted in Chapters 12 and 13. For example, the interpersonal‐psychological theory of suicidal behavior is described by Hagan, Ribeiro, and Joiner in Chapter 12, together with its history, its current status, as well as suggestions for further directions. The integrated
4 Rory C. O’Connor and Jane Pirkis
motivational‐volitional model of suicidal behavior, a tripartite model that maps the relationship between background factors and trigger events and the development of suicidal ideation/intent into suicidal behavior is outlined by O’Connor, Cleare, Eschle, Wetherall, and Kirtley in Chapter 13. In the final three chapters (Chapters 14–16) of Part I, the focus shifts to the social context of suicide. In Chapter 14, Stack and Kposowa consider sociological perspectives, including the role of marital and religious integration. The powerful effects of inequalities, economic recession, and unemployment on suicide rates across the globe receive detailed analyses in Chapters 15 and 16. Lower socioeconomic status (at an individual level) and socioeconomic deprivation (at an area level) are both risk factors, although the evidence presented by Platt in Chapter 15 suggests that the “area effect” is compositional (rather than c ontextual). The complicated relationship between an economic recession and suicide risk is emphasized by Gunnell and Chang in Chapter 16: levels of debt, house repossession, relationship difficulties, alcohol misuse, pressures on those remaining in work and job insecurity, and cuts in mental health services ought to be considered in addition to unemployment.
Part II begins with two chapters that review the evidence‐based treatment and care of suicidal children and adolescents (Chapter 17 by Gvion and Apter) and older adults (Chapter 18 by De Leo and Arnautovska). In the former, the interplay b etween biological, genetic, environmental, social, and psychological factors in the etiology and course of suicidal behavior is considered alongside the effectiveness of prevention and treatment among children and adolescents. Chapter 18 highlights the age‐specific and gender‐specific risk and protective factors in old age as well as reviewing the efficacy of existing treatment and preventative strategies. The fundamental role of the therapist and the importance of the therapeutic alliance are considered in Chapter 19 by Michel. The subsequent six chapters (Chapter 20–25) also address clinical issues concerning treatment of patients who have attempted suicide, are actively suicidal, or who have presented to hospital following self‐harm. Recent systematic reviews of studies of attitudes of self‐harm patients toward clinical services and staff attitudes toward self‐harm patients are included in Chapter 20 (by Hawton and Saunders), as is a study of service provision with recommendations for the clinical management of self‐harm patients. Results of a systematic review of aftercare interventions are also summarized in Chapter 20. The authors conclude that there is now robust evidence that short‐term psychological therapy should be routinely offered to patients following self‐harm. After reviewing the l iterature, with a particular focus on clinical practice, Mehlum and Mork’s Chapter 21 suggests a set of requirements to ensure the continuity of care of suicide attempters, and makes recommendations for policy and clinical practice. In another new chapter, Hatcher presents a systems approach (adopted elsewhere in medicine and in other industries) applied to the management of suicide risk in emergency departments (Chapter 22).
Chapters 23–25 focus on key psychological processes in suicidality and emphasize how a better understanding of such processes is integral to a range of psychotherapeutic treatments. Cognitive Therapy, Dialectical Behavior Therapy, and the Collaborative Assessment and Management of Suicidality are reviewed in Chapters 23 (by Chang, Jager‐Hyman, Brown, Cunningham, and Stanley) and 24 (by Jobes, Comtois, Brenner, Gutierrez, and O’Connor). Chapter 25 (by Williams, Duggan, Crane, Hepburn, Hargus, and Gjelsvik) explores the conditions under which suicidal ideas may persist

and escalate. It also describes mindfulness training and presents preliminary evidence that such training may be beneficial to those at risk of suicidal ideation and behavior. In the final three chapters of Part II (Chapters 26–28), different types of interventions adopting alternative modes of delivery are examined. Because it is often difficult to engage suicidal patients in treatment, interest in brief contact interventions has grown in recent years, with studies yielding promising findings in some subgroups (Chapter 26 by Milner and Carter). The role of online interventions to reduce suicide risk is considered by Kerkhof and van Spijker in Chapter 27. The authors ask whether the high expectations around online interventions have been met and highlight a number of challenges for future research. The significance of helplines in suicide p revention is explored by Woodward and Wyllie in Chapter 28. Although crisis helplines have been a mainstay of many national suicide prevention activities for decades, the authors review the evidence for their efficacy, noting the difficulties of evaluating their benefits.
Part III of the Handbook comprises 16 chapters directed at a selection of hot topics in suicide prevention. These topics bring together the different domains of research evidence, policy, and practice and highlight many of the challenges and successes in suicide prevention internationally. Part III begins with a chapter on suicide prevention in low‐ and middle‐income countries by Vijayakumar and Phillips (Chapter 29). This chapter stresses the importance of understanding suicide within the global context, recognizing that threequarters of the world’s suicides occur in low‐ and m iddle‐income countries. The international theme continues in Chapters 30 and 31. In Chapter 30, Khan, Asad, and Syed discuss suicide in Asia (the world’s largest continent, where approximately 60% of the globe’s total deaths by suicide occur). In Chapter 31, Chan and Maniam discuss the cultural factors in suicide prevention. In both chapters, research gaps are identified, and consideration is given to the establishment of culturally relevant suicide prevention programs. In Chapter 31, the authors call for stronger collaborations between the disciplines of mental health, sociology, and anthropology to facilitate better translational research. In Chapter 32, Hadlaczky, Wasserman, Hoven, Mandell, and Wasserman use case studies to compare the widely used primary, secondary, and tertiary model of suicide prevention with the U.S. Institute of Medicine model oriented toward universal, selective, and indicated approaches. In Chapter 33, drawing on evidence from across the globe, Stark, Riordan, and Dougall disentangle the relationship between the nature of rurality and suicide, following a critical dissection of the potential influence of other recognized suicide risk factors in the rural context. In Chapter 34, Mishara and Chagnon tackle the difficult issue of why a minority of people with mental health problems die by suicide. The authors argue that a better understanding of the mechanisms that may explain why mental disorder is so closely associated with suicide will improve our knowledge of why only a minority of people with mental health problems die by suicide.
The next two chapters (Chapter 35 by Chen, Wu, Wang, and Yip and Chapter 36 by Azrael and Miller) shift the focus away from factors that contribute to the development of suicidal distress to understanding how restricting access to the means of suicide can reduce suicide deaths. Although there is some overlap between the two chapters, they have a different focus, and each contributes a unique perspective to understanding the relationship between means restriction and suicide prevention.

One of the most important developments in the field of suicidology in the past 10 years has been the greater inclusion of those with lived experience (those who have lost loved ones to suicide as well as those who have been suicidal themselves) in suicide research and prevention activities. To reflect this, in Chapters 37 and 38 (by Grad and Andriessen, and Lezine, respectively), the authors describe the complexity of the bereavement process and how it impacts upon family, friends, and professionals, as well as noting the insights that those with lived experience can provide. The whole field of suicidology can benefit from these insights. The barriers to speaking out and being a lived experience advocate are also described.
In Chapter 39, Hjelmeland and Knizek critique mainstream suicidological research, and give consideration to the extent to which suicidology has disproportionately focused on explaining suicidality to the detriment of understanding it. This chapter also reviews the posited (im)balance between quantitative and qualitative methods used in international suicide research and calls for a change in direction in suicide research. Staying with the research methods focus, Chapter 40 (by Glenn, Franklin, Kearns, Lanzillo, and Nock) reviews the commonly used methods and designs for psychological studies of suicidal behavior. This chapter ends by highlighting major gaps in our knowledge that require future research. In the next three chapters (Chapters 41–43), the effect of social influences or social context on s uicidal behavior is evaluated, albeit in very different contexts. In Chapter 41, Kong, Sareen, and Katz evaluate school‐based suicide prevention programs and present recommendations for future policymaking. Chapter 42, by Pirkis, Mok, Robinson, and Nordentoft, reviews the evidence for and against the “Werther effect,” the p resumed impact of media reporting on suicide, derived from the suicide of the p rotagonist in Goethe’s (1774) novel The Sorrows of Young Werther following an ill‐fated love affair and subsequent so‐called “copycat” suicides following its publication. The emerging evidence for the positive effects of media reporting (“Papageno effect”) and the role of new media in suicide prevention are also evaluated. In the penultimate chapter (Chapter 43), Robinson, Pirkis, and O’Connor describe suicide clusters, posit various mechanisms to explain their effects, and explore approaches to prevent or reduce their impact on affected communities. In the final chapter of the Handbook (Chapter 44), McDaid makes the economic case for investing in suicide prevention. He acknowledges that every single death by suicide is a personal and social tragedy, and that placing a cost on a person’s life may seem unpalatable, but argues that if the economic case helps to shore up resources for suicide prevention (and it does help), then it is vital that this case be made. Indeed, McDaid ends Chapter 44 with the call to embed economic analyses into all evaluations of suicide prevention strategies.
We are extremely grateful to the contributors to this Handbook, all of whom responded extremely positively to our requests and queries. We hope that the material contained herein from many of the world’s leading experts in suicide research and prevention will inform suicide prevention efforts across the globe. We are also extremely passionate about enthusing and training the next generation of suicidologists, so we very much hope that the exciting and innovative research, policy, and practice detailed within this volume will act as a catalyst for others to get involved in the fight against suicide.
