Our understanding of how youth suicide occurs, whom it affects, and, by extension, how it can be prevented has grown considerably during the 35 years in which it has been a focus of my own research. When I began, a popular view—within and outside the profession—was that suicide was a reasoned choice for those facing harsh circumstances and that it was rare and unpredictable and therefore defied prediction and prevention. In the intervening period, descriptive epidemiological studies, along with research by neurobiologists and social and cognitive psychologists, have revealed that persons who exhibit suicidal behavior have a rather narrow range of clinical characteristics and that such behavior is accompanied by significantly distorted attributional styles, impulsive and sometimes aggressive behavioral patterns, and a characteristic neurobiology that cuts across the psychiatric disorders with which it is invariably associated. Once the province of the author, poet, and philosopher, suicide is now squarely in clinical territory. Despite the protestations of proponents of assisted suicide, there is now ample evidence that suicidal behavior is not an understandable response to adversity but is rather a fatal complication of an underlying mental illness that has gone untreated, has been inadequately treated, or, in some instances, is untreatable.
he clinical context">
Clinicians most commonly encounter the suicidal adolescent in the emergency department or at an emergency consultation shortly after the youth has made a suicide attempt or made a threat of suicide to a parent, sibling, teacher, or friend. The clinician’s task is to evaluate the risk of death, determine the nature of the underlying mental condition, and put in place a safe and effective treatment plan. Less often, a clinician will be asked to provide advice to a parent or to a school whose child or student has recently committed suicide.
The clinician and the teenager who has recently attempted suicide
Although completed suicide is relatively rare in adolescence (among teens aged 15—19, the rate is 8 per 100,000 teens per year), suicidal ideation and suicide attempts are more common during these years than at any other time in life. In a 12-month period, approximately 5% of male and 12% of female high school students will make a suicide attempt, and upwards of 20% of high school students will think about suicide (1). Suicide attempts are often repeated, and about half of all teen attempters will attempt to commit suicide more than once (2).
All forms of suicidality—completed suicides, suicide attempts, and suicidal ideation—are less common before puberty, perhaps reflecting a similar infrequency of depression and substance abuse. The incidence of completed suicide increases steadily through the adolescent years, peaking in the early to mid-20s. Suicide attempts, by contrast, reach a peak incidence at age 16 and then decline. Thus, while suicide is a characteristically adult behavior with beginnings that are apparent in adolescence, there is something truly "adolescent" about many suicide attempts, and this fact has considerable clinical relevance.
The adolescent nature of many suicide attempts can be discerned in the most common precipitants at this age. Stressful interpersonal interactions trigger the majority of youth suicides and attempts, often within minutes or hours of some form of dispute or disciplinary crisis (3, 4), typically a dispute with parents over limit setting, such as the timing of a curfew, or a disciplinary problem at school or with the law. As adolescence proceeds, and as parents adapt to the increasing competence of their children, these limits change, and this very flexibility could invite misunderstandings and friction. In addition, the suicide-prone teen—who is, like his or her adult counterpart, often irritable, prone to aggressive outbursts, and unduly sensitive to slights and losses (5)—lacks experience in dealing with and managing interpersonal problems with parents and friends. A disagreement that an older person might navigate with a minimum of fuss can seem unmanageable to the younger teen.
These factors lead to the striking differences in incidence between attempts and completions in the adolescent age group. Attempts are about 4,000 times more common than suicides in teen girls and about 400 times more common in teenage boys. These discrepancies, coupled with the familiar nature of many of the precipitants, present a challenge for the clinician. A tradition has developed in Europe to distance suicide attempts in the young, especially those made by females with an ineffective ingestion, from suicide, using terms such as "parasuicide" and "deliberate self-harm" in its place. The differentiation assumes that there are differences in psychopathology and natural history between young suicide completers or attempters and their older counterparts. Until these euphemisms are better defined, they may only hinder the clinician. Almost all suicide attempters, of both genders and of all ages, will say that at the time of their attempt they intended to die. Methods seem to be determined more by culture and gender than by intent. One-fifth of girls who commit suicide do so by ingestion, and in some countries, where the fatal effects of the habitual ingestants are not easily reversed by treatment, the suicide rate among females is higher than among males and is predominantly from ingestions. The clinician, aware that most attempts will not lead to death but that a small number will, walks a tightrope.
In practice, the encounter with the suicidal teen is resolved by choosing between admitting the patient to an inpatient unit, retaining the patient under observation in a day unit or emergency ward, or making arrangements for further evaluation and the initiation or continuation of regular outpatient treatment. Choosing from among these options can be made easier by a systematic appraisal of the youth’s recent suicidal and other behavior and current mental state.
The most common reason for admitting a suicidal teenager to the hospital is to ensure safe care while obtaining a more thorough evaluation or while waiting for the effects of treatment to take hold. However, hospitalization is not without costs. The teen’s friends, parents, and teachers are likely to hear of it, and negative labeling can follow. An admission can lead to a significant financial burden for the family or cause them to lose an important fraction of lifetime medical benefits. Furthermore, a hospital environment can promote contagious behaviors, such as "cutting," and hospitalization is often recalled by young people as a traumatic experience. The task of choosing between admitting, holding, or discharging the patient is therefore one that cannot be taken lightly.
The clinician can reasonably consider the following to help in making this difficult decision:
Deciding to keep the teen under observation
Continued observation is sometimes indicated until it becomes possible to obtain a detailed history from a third party, usually the teen’s parent or guardian; to arrange for an experienced mental health professional to assess mental state; and to make some assessment of problematic aspects of the home environment—for example, inadequately secured firearms or potentially lethal medications; the imminent arrival of a feared person, such as a previously abusive parent or sibling; an absence of any responsible person to meet the teen in the emergency room or to commit to bringing the teen back for a scheduled appointment; or a prevailing atmosphere of intense parent-child hostility.
If there are firearms or dangerous medications at home, the parents should be told to remove or secure them. In some instances, this may be made a condition of discharge from the emergency department, and in all instances the instruction should be carefully noted in the patient’s chart. Such warnings can significantly influence parental behavior (7).
Deciding to discharge to outpatient care
A majority of adolescent suicide attempters lose contact with the clinic where they were first seen after one to three outpatient visits (8, 9). This attrition rate is somewhat higher than is usually seen with teen patients, and it might reflect the self-regulating effect of many suicide attempts, whereby the patient feels better after the attempt. It might also reflect the perceived relevance and helpfulness of the treatment offered or poor administrative procedures that allow referrals to fall through the cracks. Given that many of the attempters will go on to attempt suicide again, there is no room for complacency in this aspect of management.
Antidepressants should not be prescribed until the clinician has had an opportunity to reevaluate the patient’s mood state after the current crisis is over. If the patient is clearly depressed at the time of the attempt, hospital admission would be preferable to arranging outpatient treatment.
Clinicians often propose to "contract for safety" with a suicidal teen before discharging the youth. While this approach might convey to the patient that he or she is being taken seriously, the clinician should not be overconfident about its value. Follow-up studies of repeat attempters indicate that as many as a third had previously signed such a contract (10). That said, preparing a contract can provide an opportunity for the clinician to assess and rehearse how the patient would respond if he or she again encountered the stressor that led to the recent behavior.
Other forms of intervention in the emergency department have been tried, notably convening a family meeting to examine the recent crisis and aspects of family dysfunction (11), but this approach has a limited effect in securing attendance at later appointments.
The patient should ideally be discharged from the emergency department only after an appointment has been scheduled. If this is not possible, the clinician should assume responsibility for asking an assistant or a colleague to contact the patient’s home with an appointment as soon as possible after discharge or else retain the patient in the emergency department until a precise disposition plan can be arranged. A failure to do this and a failure to note it in the chart could render the clinician liable in the event of a later attempt or death.
The goal of hospitalization after a suicide attempt is to secure the patient until treatment has reduced the risk of suicide. A small number of inpatient units provide specialized therapeutic care for the suicidal teenager, but inpatient stays are usually brief, and there are no intervention models known to be effective that require inpatient care.
Secure hospitalization depends on effective evaluation of suicidality, clear criteria and procedures for close observation, and the nature of the physical environment. All are important, but the aspect that falls most heavily on the clinician is the evaluation of persistent suicidality. Evidence of persistent suicidality might come from comments heard by nursing staff or other patients, so nurses’ notes should always be checked. Suicidality is especially likely after disturbing visits or telephone calls with friends or family, and such events can be a useful focus in the regular interviews with the patient. The routine use of self-completed rating scales, such as the Beck Suicide Intent Scale (12) and the Beck Depression Inventory, to track daily changes in mental state is not widespread. However, there is evidence that suicidality is more likely to be disclosed in a self-report instrument than in interviews, so the use of such scales could prove helpful. Most inpatient suicides occur shortly after discharge (13), and thus a decision to discharge a patient within a short time of reported suicidal utterances should be taken only after obtaining a second opinion.
Although procedures for close observation vary from unit to unit, the mental state that is potentially the most dangerous, namely, one of disorganization and agitation, should be dealt with by one-on-one arm’s-length supervision. The structural features of a "safe" ward should include low-weight-breakage hooks and bars in showers and closets; untiled, single-surface ceilings; concealed hinges; recessed showerheads, toilet paper holders, and fire extinguishers; and low-set grab bars and door handles.
A small number of suicidal adolescents maintain their intent to commit suicide for a long time (14). Despite ample precautions, they may continue to attempt suicide, even in a ward setting, by, for example, eating powdered glass, trying to stab themselves with pens, and so on. These teenagers are not well described in the literature, and their management poses a challenge. They will often remain hospitalized for considerable periods. No patient should be discharged until an early follow-up appointment has been made.
A small number of suicidal teens will have a diagnosis of bipolar disorder or schizophrenia. There is now an abundance of evidence, drawn predominantly from adult studies, that treatment with lithium for those with bipolar disorder (15) and with clozapine for schizophrenia (16) reduces the risk of later suicide and suicide attempts.
In most instances, the suicide attempter is volatile, oversensitive, and irritable. Perceived or actual humiliation or rebuffs generate thoughts of hopelessness and futility or, at times, anxiety or anger, and the suicidal response follows. Treatments need to address this model. One can postulate that antipsychotics would reduce sensitivity, irritability, and impulsive behaviors. An early random-assignment study of the antipsychotic drug flupenthixol significantly reduced the number of attempts in a group of frequent attempters (17).
It is common practice in treating teen attempters to prescribe a selective serotonin reuptake inhibitor (SSRI) or another antidepressant after an attempt. However, there is a paucity of research on the efficacy of these agents in suicidal adolescents. Even among adults, few studies have targeted suicidal behavior, although in small open-label trials, SSRIs have been shown to decrease suicidal ideation in young adults with borderline personality disorder (18).
Reports of emergent suicidality during the course of SSRI treatment of mood disorders has led to a reevaluation of the treatment. Reviews of data sets from large randomized controlled trials with patients with major depressive disorder, anxiety disorders, or obsessive-compulsive disorder (19, 20) found either no effect or a decrease in suicidality during active treatment. By contrast, data derived from 11 published and unpublished SSRI trials for depressed children show an excess of suicide-related adverse events when on active treatment, but no suicides (21). It is not clear why treatment-related suicidality shows up only in unstandardized event reports and is not reflected in reliable standard measures that address the same symptoms. Clearly, however, with a recently suicidal patient, starting treatment with an antidepressant should be undertaken with care. The effect does not appear to be specific to SSRIs, and there is evidence that suicidal events increase during treatment with tricyclic antidepressants as well as in patients with Parkinson’s disease after subthalamic stimulation. The mechanisms of these phenomena, if they are confirmed, are not known. Explanations include adverse psychological consequences of medically induced psychomotor activation outpacing recovery from the cognitive distortions of depression.
When using an SSRI, it is advisable to start with a lower than usual dose—say, 10 mg of fluoxetine—and caution the parents and the patient about the onset of feelings of agitation, hopelessness, and suicidality. In the event that such feelings occur, the dose should be reduced before starting a gradual upward titration. It may also be useful to supply the parents with a small quantity of an atypical antipsychotic to be used in the event of agitation.
Psychotherapy for the suicidal behavior
For the most part, treatment is directed to comorbid conditions, and few patients will be directed to a program designed specifically to address suicidal responses themselves. A number of studies have been conducted in which ready access to a clinician or other clinical services was offered in the event of a further suicidal crisis, but such access does not seem to reduce the chances of repetition (22).
In developing a more specific therapy, the patient and the clinician should first attempt to undertake a chain analysis of the events during the 24 hours preceding the attempt. It might then become clear that the attempt lay at the end of a cascade of events, thoughts, and feelings. Cognitive distortions and misrepresentations can become obvious during this treatment, and they can form the focus of a later psychotherapeutic approach. Paying attention at this level of detail can also help the teenager discover the patterns that provoke suicidality and might itself be therapeutic.
Dialectical behavior therapy, an adaptation of cognitive behavior therapy developed by Marsha Linehan (23), is a psychotherapeutic approach that addresses this chain of behavior. In Linehan’s adapted model, interpersonal stressors lead to mood and thought changes that might be relieved by attempting suicide or by self-cutting. The behavior is reinforced because of the relief of negative mood that it offers and, to some extent, by enhanced attention following the behavior.
Dialectical behavior therapy has been shown in adults to be effective in reducing suicidal behavior. However, it requires intense involvement over a 12-month period, and relatively few trained therapists are available to administer it. Nevertheless, some elements within the treatment package can be usefully adopted by the practicing clinician, although their value in isolation remains to be demonstrated.
The conventional dialectical behavior therapy treatment package aims to do the following:
Until dialectical behavior therapy is more widely available or affordable, the sensible clinician will keep these different goals in mind and employ them as their skills permit. To use them, however, the clinician will need a good sense of the contingencies of the pattern of suicidal thoughts and behaviors, which can be gained through the chain analysis outlined above.
The process of monitoring and noting the contingencies of suicidal thoughts will not always point to a stressful interpersonal interaction. The clinician will sometimes discover that the behavior is triggered by episodes of free-floating anxiety or by fear-inducing feelings—for example, at night before sleep—and, at other times, they will reveal a state of ongoing depression.
ssistance to survivors">
The suicidal death of a teenager leaves survivors who may be grief stricken, traumatized, and filled with a sense of responsibility and culpability. They will sometimes seek a consultation for themselves or will ask for advice on how best to deal with the reactions being shown by their other children. Survivors of all ages ask whether something they did or said could have provoked the death or whether the tragedy might have been averted if they had reacted differently to some subtle or ambiguous cue. Whether with families who have sought to better understand a suicide or with families that are sought out in the course of research, the psychological-autopsy process, which provides insight into the great similarities among suicide victims, tends to be met with relief.
Community assistance after a student commits suicide
A psychiatrist or other clinician might be called in to advise the school after a student has committed suicide. After a student’s suicide, certain consequences are quite common:
The clinician advising a school first needs to understand the nature of the suicide victim and the circumstances of the suicide. A good starting point is to interview and work with the victim’s family. The information obtained will allow the clinician to put the suicide into a more or less accurate context. While it will not usually be appropriate or possible to disclose the individual factors that made the youngster vulnerable to suicide, this knowledge will allow the clinician to speak with authority about how completed suicides nearly always occur in the context of a preexisting psychiatric condition and how important it is that such conditions be recognized and appropriately treated. The impact of such a message will be to reduce blame and guilt.
The complication that causes most concern to schools and communities is the risk of contagion. Contagion accounts for 5%—10% of all youth suicides; it is especially common after a suicide that has been widely publicized in the press, such as occurs with a suicide committed in front of other people. Such events are, of course, newsworthy, and discouraging coverage would be difficult. The Centers for Disease Control and Prevention in collaboration with the American Foundation for Suicide Prevention (24) and the University of Southern California’s Annenberg School of Journalism have published guidelines about responsible reporting of youth suicide that discourage the inclusion of photographs or graphic descriptions of the method used, discourage any romanticizing of the reasons for suicide, encourage an emphasis on the relationship of the suicide to an associated psychiatric disorder, and encourage the inclusion of information about resources for treatment of depression and suicidality.
The teenager whose suicide is part of a cluster will usually have known about, but not personally known, the first victim of the cluster. He or she will usually have a history of previous suicidal behavior or other mood or behavior disturbance. In some cases, a school screening program has been instituted to identify students who have made previous suicide attempts or who are depressed and to single them out for evaluation and, if necessary, treatment.
School officials often ask whether holding a special ceremony to mark the death of the child will promote imitation. A failure to mark the student’s death can instill feelings of anger toward the school, which would not be helpful. A memorial ceremony that is informed by the nature of suicide as a complication of an underlying mental illness and that avoids romanticizing and misrepresenting the event would be respectful and might be helpful. The informed clinician is in an ideal position to counsel on the preparation of such a ceremony.
The clinical management of the suicidal teenager requires well-developed clinical skills. In addition to the basic qualities of warmth, curiosity, and humor, a good knowledge of the mechanisms through which the decision to attempt suicide is made—and how that often recurring pattern can be interrupted, whether with the use of behavioral skills, by improving insight, or with appropriate medication—can often bring a degree of life-saving relief to this common condition.
