  extras—it had better go that way than for more pills and more doc-

  tor bills.” To her daughters, she writes, “Try to forgive me for what

  I’ve done—your father would be so much better for you. It will be

  harder for you for awhile—but so much easier in the long run—I’m

  getting you all mixed up.”19

  Another example: “I started to list the people who wouldn’t mind

  if I wasn’t around. I clearly wasn’t a good wife for my ex-husband. He

  wouldn’t miss me. And I never felt that comfortable in my role as a

  mom—didn’t feel like I was a good mom necessarily . . . It’s like I’ll

  be a burden off their backs. Clearly their lives will be enhanced be-

  cause I’m not around. At that point, I honestly felt I was doing them

  a favor.”20

  Alvarez quoted a man who had spent most of his life in mental in-

  stitutions: “If I commit suicide, it will not be to destroy myself but to

  put myself back together again. Suicide will be for me only one

  means of violently reconquering myself . . . By suicide I reintroduce

  my design in nature, I shall for the first time give things the shape of

  my will.”21 A paraphrasing of his words would be that “I feel so inef-

  fective that I focus on one sure way I can have dramatic effect,

  namely my own death by suicide.” The man’s words can also be seen

  as another example of the blending of life and death that I believe oc-

  curs in at least some instances of serious suicidal behavior. In Chap-

  ter 2, I described Shneidman’s example of Ariel, who viewed things

  in the cemetery as “graceful” and “gracious.” The blending seemed to

  be of death by suicide with beauty and caring. In this man’s example,

  by contrast, the blending seems to be of death by suicide with a lively

  sense of taking charge and imposing will. One type seems to involve

  seeing suicide as a means to belong or be cared for; the other type as

  a means to feel effective—these types correspond to the bedrock is-

  sues of thwarted belongingness and perceived burdensomeness.

  Research studies also show a connection between feeling ineffec-

  tive or being a burden on the one hand, and feeling suicidal on the

  other. In the sections below, this work is summarized, starting with

  104 ● WHY PEOPLE DIE BY SUICIDE

  research on the general connection between depressive symptoms

  (one of which is suicidality) and experiences of ineffectiveness, espe-

  cially in social domains.

  Social Skills and Depression

  There is little doubt that depression and suicidality are associated

  with social skills problems.22 People with depression consistently eval-

  uate their own social skills more negatively than do nondepressed

  people23—this result applies to depressed children as well as de-

  pressed adults.24

  Given the pessimistic outlook associated with depression and

  suicidality, it is not too surprising that depressed people evaluate

  their social skills negatively. But is there an objective basis for their

  negative evaluations; that is, do others also rate their social skills neg-

  atively? In fact, when observers or conversational partners rate de-

  pressed people’s social skills, a common finding is that depressed

  people’s skills are rated as lower than those of nondepressed con-

  trols.25

  A related line of research has examined the communication be-

  haviors of depressed versus nondepressed people. For example, as

  compared to nondepressed people, depressed people speak more slowly,

  and with less volume and voice modulation; depressed people have

  longer pauses in their speech patterns, and take longer to respond

  when someone else addresses them.26 Voice modulation and rate ac-

  count for the animated and appealing qualities of speech; because

  depressed and suicidal people’s speech often lacks these qualities,

  they are often negatively perceived by others.

  In addition to the quality of speech, the content of speech in de-

  pression has been evaluated. In studies of married couples with a de-

  pressed member, themes involving dysphoric feelings and negative

  self-evaluation were likely to emerge in their conversations.27 It has

  been found that depressed people may be at their most expressive

  The Desire for Death ● 105

  with their spouses when they are discussing negative issues.28 There is

  some evidence that negativity in social interactions is particularly

  likely to emerge between depressed people and intimate relationship

  partners (as opposed to strangers or nonintimate acquaintances).

  For example, in a study of depressed and nondepressed students dis-

  cussing “events of the day” with either a friend or a stranger, re-

  searchers reported that depressed students tended to withhold nega-

  tive verbal content when talking with strangers but were more likely

  to disclose negative topics when talking with a friend.29 Other work

  has found that depressed people are more likely than nondepressed

  people to make unsolicited negative self-disclosures.30 This problem

  may be particularly acute in relationships between depressed people

  and intimate others. Depressed and suicidal people, then, are likely

  to instill negative views of themselves in others, perhaps especially

  those close to them.

  This research shows that depressive symptoms (a key one of which

  is suicidality) are associated with feelings of social ineffectiveness,

  and that these may manifest particularly in close relationships. These

  findings are roughly consistent with the view espoused here, that an

  extreme form of ineffectiveness, perceived burdensomeness, is impli-

  cated in suicidality, but it would be more satisfying if studies focused

  specifically on perceived burdensomeness and suicidality. In the next

  section, several such studies are summarized.

  Perceived Burdensomeness Contributes to Suicidality

  To my knowledge, five studies have been framed as direct tests of

  the possibility that perceived burdensomeness is involved in seri-

  ous suicidal behavior; all five affirm the connection. One study was

  conducted to test DeCatanzaro’s model of self-preservation and self-

  destruction.31 Arguing from a sociobiological or evolutionary stand-

  point, this model posits that staying alive actually may reduce inclu-

  sive fitness for an individual if the individual is low in reproductive

  106 ● WHY PEOPLE DIE BY SUICIDE

  potential and if the individual’s continuing to live poses such a bur-

  den to close kin that it costs them opportunities for reproduction.

  One upshot of this view is that suicidal behavior may have been se-

  lected for in the course of evolution—a controversial point to which

  I return later.

  To test this model, Brown and colleagues conducted a question-

  naire study of college students and found the predicted correlation

  between feeling a burden on kin and suicidality. Burdensomeness

  stood out as a unique and specific predictor of suicide-related symp-

  toms even when other variables, such as the individual’s repr
oductive

  potential, were accounted for.32

  My students and I also conducted empirical tests of the associa-

  tion between perceived burdensomeness and suicidal behavior. We

  trained raters to evaluate actual suicide notes regarding the following

  dimensions: perceived burdensomeness, hopelessness, and general-

  ized emotional pain. The raters read each note and then made three

  separate ratings on a 1-to-5 scale of the amount of perceived burden-

  someness, hopelessness, and generalized emotional pain conveyed

  by the note.

  Unknown to the raters, half of the notes were from people who

  died by suicide, and half were from people who attempted suicide

  and survived. The goal of the study was to compare perceived bur-

  densomeness versus Shneidman’s emphasis on emotional pain versus

  Beck’s emphasis on hopelessness. In statistical analyses, the notes

  from those who died by suicide contained more perceived burden-

  someness than notes from attempters; no effects were found regard-

  ing hopelessness and emotional pain. This study’s relatively strin-

  gent comparison of notes from those who died by suicide to notes

  from those who attempted and survived (which distinction was un-

  known to raters), with perceived burdensomeness emerging as the

  only unique predictor of death by suicide, added to our confidence in

  the results.33

  The Desire for Death ● 107

  Moreover, a second study from this same paper on a separate col-

  lection of notes took a similar approach, except that all notes were

  from those who died by suicide, and perceived burdensomeness,

  hopelessness, and generalized emotional pain were used as predic-

  tors of lethality of suicide method (e.g., self-inflicted gunshot wound

  was viewed as relatively more lethal than overdose). Here again, per-

  ceived burdensomeness was a significant predictor of lethality, whereas

  hopelessness and generalized emotional pain were not. The conver-

  gence of the two studies made the findings more persuasive.

  A survey on reproductive behavior, quality of family contacts, and

  suicidal ideation on several hundred community participants as well

  as on five high-suicide-risk groups (e.g., general psychiatric patients

  and incarcerated psychiatric patients) found that perceived burden-

  someness toward family and social isolation were especially corre-

  lated with suicidal ideation.34 It is important to note that these two

  variables correspond to two of the three main aspects of the present

  model, burdensomeness and lack of belonging.

  My students and I recently completed a study on perceived bur-

  densomeness and suicidality among 343 adult outpatients of the

  Florida State University Psychology Clinic. Areas of diagnosis for

  these patients were represented in the following proportions: 39 per-

  cent mood disorder, 14.6 percent anxiety disorder, 6 percent sub-

  stance use disorder, 12.2 percent personality disorder, 9 percent ad-

  justment disorder, and 18 percent other disorders.

  We hypothesized that perceived burdensomeness would directly

  relate to both past number of suicide attempts and an index of

  current suicidal symptoms, and furthermore, that this relationship

  would exist even when accounting for known risk factors such as

  personality disorder status, depressive symptoms, and hopelessness.

  This is similar to the “kitchen sink” approach in our paper described

  in the last chapter. We also wanted to see if there was a special con-

  nection between perceived burdensomeness and suicidality. So, for

  108 ● WHY PEOPLE DIE BY SUICIDE

  purposes of comparison, the associations of hopelessness to suicide

  indices (controlling for personality disorder status, depressive symp-

  toms, and perceived burdensomeness) were examined. Our reason-

  ing was that if perceived burdensomeness is important in suicidality,

  its associations to suicidality should be as rigorous as those regarding

  the documented risk factor of hopelessness.

  Here, as in other studies, the connection of perceived burden-

  someness to suicidality was supported. Specifically, there was an as-

  sociation between measures of perceived burdensomeness and sui-

  cidality, and this association persisted even when a host of other

  variables was accounted for (specifically, age, gender, hopelessness,

  depressive symptoms, and personality disorder status). Furthermore,

  the link between perceived burdensomeness and suicidality was at

  least as strong as that between hopelessness and suicidality.

  Other Research on Burdensomeness and Suicidality

  Although not direct tests of the burdensomeness view of suicidality,

  several other studies have reported results consistent with this per-

  spective. For example, in a study on genuine suicide attempts vs.

  nonsuicidal self-injury, genuine attempts were defined as those with

  lethal intent and bodily injury; nonsuicidal injury involved things

  like superficial cuts made without the intent to die. The researchers

  reported that genuine suicide attempts were often characterized by

  a desire to make others better off, whereas nonsuicidal self-injury

  was often characterized by desires to express anger or punish one-

  self.35 “Making others better off ” is similar in concept to perceived

  burdensomeness. In this study, as in those reviewed earlier, an index

  related to perceived burdensomeness was associated with relatively

  severe suicidal behavior. Persuasive aspects of the study were that

  suicide attempters were compared to a compelling control group

  (those engaging in nonsuicidal self-injury), and that effects of burden-

  someness were compared to effects of other relevant dimensions,

  The Desire for Death ● 109

  such as anger expression and self-punishment, with burdensomeness

  emerging as among the most important.

  One might imagine that feelings of burdensomeness might be

  particularly acute among depressed, terminally ill people. In fact,

  Filiberti and colleagues studied vulnerability factors for suicide in

  five terminal cancer patients who died by suicide while they were

  cared for at home by palliative care teams.36 Of all the various possi-

  ble factors identified, being a burden on others was judged to be one

  of the two most important. Interestingly, the other was fear of the

  loss of general competence, which, according to the current model, is

  a related but weaker form of perceived burdensomeness. In a study

  mentioned earlier on 3,005 psychiatric patients at risk for suicide, of

  whom thirty-eight died by suicide within two months of evaluation,

  nine clear risk factors were identified, among which were feelings of

  being a burden on others.37

  O’Reilly and colleagues reached similar conclusions. They studied

  psychiatrists’ reports on their patients’ suicides, and of the three vari-

  ables seen as frequently present in the month preceding suicide, one

  was “feeling a burden on others.” The two others, incidentally, were

  related to thwarted belongingness—social withdrawal and turning

  down help from others.38r />
  If burdensomeness were involved in suicidality, one might expect

  that suicidal patients’ self-views would be especially discrepant from

  how they view other people. In a telling study, researchers compared

  self-views as well as views of other people among suicidal patients

  and psychiatric and nonpsychiatric controls. Not surprisingly, the

  suicidal patients endorsed more negative self-views than the other

  two groups, similar to the research reviewed earlier in which de-

  pressed people evaluated their social skills negatively. Notably, the

  suicidal patients rated other people more favorably than did the

  other two groups.39 The conclusion is that suicidal people view

  themselves in quite negative terms, and this is particularly true when

  110 ● WHY PEOPLE DIE BY SUICIDE

  their self-views are compared to their views of other people. This

  marked discrepancy in suicidal people between self-ratings and

  views of others could instill a sense of burdensomeness—the idea

  that “I’m bad but I’m especially bad when compared to others, who

  are good.”

  A roughly similar dynamic emerged in a study of chronically ill

  patients. The researchers predicted that among chronically ill pa-

  tients who are dependent on a caregiving spouse (but whose health

  status prevents their reciprocating the care), receipt of support may

  exacerbate feelings of burdensomeness, and thus may increase sui-

  cidality. This hypothesis was in “grave danger of refutation” (Popper,

  1959), given the pervasive positive associations between social sup-

  port and health. But the hypothesis survived the test—the study

  found a positive correlation between social support and suicidal ideation among physically ill participants.40

  The concept of perceived burdensomeness is fairly easy to under-

  stand as applied to adults—the image of the failed breadwinner

  imagining his family will be better off without him is tragic but not

  hard to conceive. But what about perceived burdensomeness as ap-

  plied to younger people, including children? Young people do die by

  suicide, and so if perceived burdensomeness plays a role in suicide in

  general, it should be applicable to youth too. In fact, researchers have

  studied burdensomeness and suicidality in youth in their work on

  the “expendable child.”41 These authors hypothesized that suicidal
