Psychiatric risk factors for adolescent suicide: a case-control study

OBJECTIVE The objective of this study was to determine the psychiatric risk factors for adolescent suicide. METHOD Sixty-seven adolescent suicide victims were compared with 67 demographically matched community controls. Psychiatric disorder was assessed in suicide victims using a psychological autopsy protocol and in controls using similar semistructured psychiatric interviews. Risk factors were quantified by use of the odds ratio (OR), that is, the relative frequency of the occurrence of a given condition in the suicides compared with the controls. RESULTS The most significant psychiatric risk factors associated with adolescent suicide were major depression (OR = 27.0), bipolar mixed state (OR = 9.0), substance abuse (OR = 8.5), and conduct disorder (OR = 6.0). Substance abuse was a more significant risk factor when comorbid with affective illness than when alone (OR = 17.0 versus 3.3). The majority of depressed suicide victims had a primary affective disorder (82%). A significant minority (31%) of depressed suicide victims had been depressed less than 3 months. Previous suicide attempts, suicidal ideation, and homicidal ideation also were associated with adolescent suicide. CONCLUSIONS The development of effective treatments for youth who fit the above-noted risk profiles should be given high priority.

Suicide in Adolescents with No Apparent Psychopathology

OBJECTIVE To delineate the characteristics of adolescent suicide victims with no apparent psychiatric disorder. METHOD Seven adolescent suicide victims with no apparent disorder were compared with 60 suicide victims with definite or probable psychiatric disorder, and with 38 community controls with no psychiatric disorder. RESULTS Suicide victims without psychiatric disorder, compared with the remainder of suicides showed lower rates of past psychiatric treatment, previous suicide attempt, family history of affective illness, total life stressors over the previous 12 months, and a greater prevalence of the availability of a loaded gun in the home. The seven suicide victims compared with the 38 psychiatrically normal community controls, showed a higher rate of familial psychiatric disorder, past suicidal ideation or behavior, legal or disciplinary problems in the past year, and firearms in the home, particularly those that were loaded. CONCLUSION Even suicide victims without apparent psychiatric disorder still show some evidence of psychiatric risk factors compared with community controls. However, prevention of suicide in this group is probably best achieved by restriction of the availability of firearms, particularly loaded ones. The clinician should pay particular attention to suicidal risk in youth who are confronting legal or serious disciplinary crises and should take suicidal ideation seriously even in the absence of clear psychopathology.

Antecedents and Sequelae of Sudden Parental Death in Offspring and Surviving Caregivers

OBJECTIVES To examine the psychiatric antecedents that put parents at risk for early death, and the psychological sequelae of bereavement in offspring and caregivers. DESIGN A population-based study. SETTING Bereaved families were recruited through the coroners records and by advertisement. Control families were recruited by random-digit dialing and advertisement. PARTICIPANTS Families with biological offspring from 7 to 25 years of age in which 1 parent died of suicide, accident, or sudden natural death were included (n = 140). Controls (n = 99) had 2 living parents and their biological offspring and had no death of a first-degree relative within the past 2 years. MAIN OUTCOME MEASURES Lifetime psychiatric history for deceased parents (probands) and new-onset psychiatric disorders, self-reported symptoms, and functional status in offspring and surviving caregivers. RESULTS Bipolar disorder, substance abuse, and personality disorders are more common in probands who died of suicide or accident than in control parents. Bereaved offspring and their caregivers were at increased risk for depression and posttraumatic stress disorder. Bereaved offspring had a 3-fold (95% confidence interval, 1.3-7.0) increased risk of depression, even after controlling for antecedent and concomitant risk factors. Offspring bereaved by suicide showed similar outcomes compared with those bereaved by other types of death. CONCLUSIONS Bereavement conveys an increased risk of depression and posttraumatic stress disorder above and beyond other vulnerability factors. Better integration of medical and psychiatric care may prevent premature parental death, but once it occurs, physicians should be alert to the increased risk for depression and posttraumatic stress disorder in bereaved offspring and their caregivers.

Suicide in affectively ill adolescents: a case-control study.

Sixty-three adolescent suicide victims with a history of affective illness were compared to 23 adolescent community controls with a lifetime history of affective illness, using a case-control design. Suicide victims were more likely to have had major depression, comorbid substance abuse, a past suicide attempt, family history of major depression, treatment with a tricyclic antidepressant, history of legal problems, and a handgun available in the home. There was a non-significant trend for bipolar depression to convey a higher risk for completed suicide than unipolar depression. Recommendations for the prevention of suicide among those with early onset affective illness are discussed in light of these findings.

Psychiatric sequelae to the loss of an adolescent peer to suicide

OBJECTIVE This study was designed to learn whether friends and acquaintances of suicide victims were at increased risk for depression, post-traumatic stress disorder, and suicidal behavior after exposure to suicide. METHOD The social networks of 26 adolescent suicide victims, consisting of 146 adolescents, were interviewed 7 months after the death of the suicide victim and compared with 146 matched, unexposed controls. RESULTS The rates of these disorders that had onset after exposure were elevated in the exposed group vs. controls: major depression, post-traumatic stress disorder, suicidal ideation with a plan or an attempt, but not suicidal attempts. Almost all of those exposed youth who developed new-onset suicidality did so in the context of a new-onset depressive episode. The majority of these new-onset depressive disorders began within 1 month of exposure. CONCLUSION Postvention programs not only should focus on the prevention of imitation of suicidal behavior, but also should provide longer term follow-up for potentially bereaved and depressed youth exposed to suicide.

Posttraumatic stress disorder in peers of adolescent suicide victims: predisposing factors and phenomenology

OBJECTIVE To examine the factors predisposing to posttraumatic stress disorder (PTSD) in peers of adolescent suicide victims. METHOD One hundred forty-six adolescents who were the friends of 26 suicide victims were studied. Five percent (n = 8) developed PTSD after exposure to suicide. These 8 subjects with PTSD were compared to the remainder of the exposed subjects (n = 138). RESULTS Subjects with PTSD were more likely than those without PTSD to have had a history of substance abuse, agoraphobia, and suicide attempts. Subjects who developed PTSD were more likely to have developed a new-onset depression, to have more severe grief, and to have been closer to the suicide victim. Subjects with PTSD tended to have more severe exposure to suicide and came from discordant households with a history of disruptions in key relationships. The 8 subjects who developed PTSD were compared to 38 subjects who developed new-onset depression but not PTSD. Those with PTSD were more likely to have had past substance abuse, prior suicide attempts, family history of panic disorder, a history of parent-child disruption, and a history of loss. Symptoms of intrusive visual images, hypervigilance, and avoidance of reminders discriminated subjects who had PTSD from new-onset depressives without PTSD. CONCLUSIONS PTSD is an expectable outcome in youth exposed to suicide. Further work is required to differentiate symptoms of depression from PTSD.

The validity of diagnoses obtained through the psychological autopsy procedure in adolescent suicide victims: use of family history

A test of validity of the psychiatric diagnoses obtained by the psychological autopsy procedure is described in a consecutive series of 67 adolescent suicide victims. Family history of mental illness in first‐degree relatives of subjects was obtained blind to subject diagnosis using the family history method. It was hypothesized that subjects with a given diagnosis, compared with subjects without this diagnosis, would show an increased rate of this disorder among first‐degree relatives. This hypothesis was supported insofar as specific associations between subject diagnosis and familial rates of illness were demonstrated for major depression, bipolar illness, conduct and antisocial disorder and substance abuse. These results provide further support for the validity of diagnoses obtained through the psychological autopsy procedure.

Psychiatric Effects of Exposure to Suicide among the Friends and Acquaintances of Adolescent Suicide Victims

The friends and acquaintances (N = 58) of 10 adolescent suicide victims were interviewed 6 months after the death of the victims, and the rates of psychiatric disorders that had onset after the death were compared with the 6-month incidence of psychopathology in 58 demographically and psychiatrically matched unexposed controls. The exposed group showed higher rates of any new onset major depressive disorder, but the rate of incident suicide attempts was the same in both groups. The median onset of incident depression among the exposed group was within the first month after exposure, and the majority of those exposed youth with incident depression were still depressed at interview 6 months after the death. Adolescent friends and acquaintances of suicide victims experience considerable psychiatric morbidity subsequent to exposure to suicide, most consistent with pathological grief.

The Presence and Accessibility of Firearms in the Homes of Adolescent Suicides

OBJECTIVE The presence of guns in the home, the type of gun, and the method of storage were all hypothesized to be associated with risk for adolescent suicide. DESIGN Case-control study. SUBJECTS The case group consisted of 47 adolescent suicide victims. The two psychiatric inpatient control groups were 47 suicide attempters and 47 never-suicidal psychiatric controls, frequency-matched to the suicide victims on age, gender, and county of origin. SETTING The cases were a consecutive community sample, whereas the inpatients were drawn from a university psychiatric hospital. MAIN OUTCOME MEASURE Odds of the presence of guns in the home of suicide victims (cases) relative to controls. RESULTS Guns were twice as likely to be found in the homes of suicide victims as in the homes of attempters (adjusted odds ratio, 2.1; 95% confidence interval, 1.2 to 3.7) or psychiatric controls (adjusted odds ratio, 2.2; 95% confidence interval, 1.4 to 3.5). Handguns were not associated with suicide to any statistically significantly greater extent than long guns. There was no difference in the methods of storage of firearms among the three groups, so that even guns stored locked, or separate from ammunition, were associated with suicide by firearms. CONCLUSIONS The availability of guns in the home, independent of firearms type or method of storage, appears to increase the risk for suicide among adolescents. Physicians should make a clear and firm recommendation that firearms be removed from the homes of adolescents judged to be at suicidal risk.

Major Depression or Uncomplicated Bereavement? A Follow-up of Youth Exposed to Suicide

OBJECTIVE To determine whether the depressive reactions experienced by youth exposed to suicide were uncomplicated bereavement or major depression by examining the longitudinal risk of recurrent major depression. METHOD The 121 friends and acquaintances of 26 adolescent suicide victims were followed up 1 to 18 months after an initial interview that took place around 6 months after the death of the suicide victim. A demographically similar group of 138 unexposed controls was also followed up. RESULTS The median duration of depression in the 37 subjects who became depressed after exposure was 8 months. The exposed group, compared with controls, had a higher rate of incident depression (RR = 1.7, 95% Cl = 1.0-2.8) during the follow-up period, even after adjustment for previous history of depression and other risk factors for depression. Within the group of exposed subjects, the rate of depression on follow-up was highest in those who developed a depressive disorder before exposure to suicide, intermediate in those who developed depression after exposure, and lowest in those who were not depressed at the first interview after exposure. There was no evidence of an increased incidence of suicide attempts in the exposed group relative to the unexposed controls on follow-up. CONCLUSIONS The depressive reactions observed in youth exposed to suicide are most consistent with major depressive episodes on the basis of course and risk of recurrence. Exposure to suicide was associated with an increased risk of recurrent depression but not with an increased long-term risk of suicidal behavior.
