Suicidal behaviour during different phases of bipolar disorder

BACKGROUND: There are no previous studies comparing the prevalence and risk factors for suicidal behaviour during different phases of bipolar disorder. METHODS: In the Jorvi Bipolar Study (JoBS), 1630 psychiatric in- and outpatients were screened for bipolar disorders with the Mood Disorder Questionnaire. Using SCID I and II interviews, 191 patients were diagnosed with bipolar disorders (90 bipolar I, 101 bipolar II). Suicidal ideation was measured using the Scale for Suicidal Ideation (SSI). Prevalence and risk factors for ideation and attempts during different phases (depressive, mixed, depressive mixed and hypomanic/manic phases) were investigated. RESULTS: There were marked differences between phases regarding suicide attempts and level of suicidal ideation. Hopelessness predicted suicidal behaviour during the depressive phase, whereas a subjective rating of severity of depression and younger age predicted suicide attempts during mixed phases. LIMITATIONS: The relatively small sample size in some phases. CONCLUSIONS: Suicidal behaviour varied markedly between different phases of BD. Suicide attempts and suicidal ideation were related to phases which are associated with depressive aspects of the illness. Hopelessness and severity of depression were key indicators of risk in all phases.     

Suicidal events and accidents in 216 first-episode bipolar I disorder patients: predictive factors

BACKGROUND: Risks of life-threatening behaviors are high among bipolar disorder (BPD) patients, but early rates and associated risk factors for suicides and accidents remain ill-defined. METHODS: We assessed 216 DSM-IV BP-I patients prospectively for 4.2 years from first-lifetime hospitalization, using ordinal logistic-regression to estimate risks and associated demographic and clinical factors among risk-groups with: [1] no suicidal ideation, acts, or accidents, [2] suicidal ideation only, [3] suicides and attempts, [4] accidents, and [5] both suicidal acts and accidents. RESULTS: Suicidal thoughts or acts were identified in 127/216 subjects/4.2 years (14%/year), including suicidal ideation in 88 (9.7%/year), and acts in 39 (4.3%/year: 38 attempts [17.6%/year], 1 suicide [0.11%/year]); 87% of acts occurred within a year of a first-episode. Life-threatening accidents occurred in 20 cases (2.2%/year) with a mean latency of 3.8 years, including 12 with suicidal ideation or attempts (60% co-occurrence of accidents and suicidality); alcohol was implicated in 25% of accidents. The 53 cases of violent behaviors (5.84%/year) included a fatal car-wreck and a suicide, for a mortality risk of 0.22%/year (2/216/4.2 years). Suicidality was associated with initial mixed-state, proportion of follow-up weeks in mixed-states or depression, and prior suicide attempts; accidents were associated selectively with initial mania or psychosis, later mania or hypomania, and alcohol abuse. Violent acts also were associated with use of more psychotropic medicines/person, and with use of antipsychotics or sedative-anxiolytics. LIMITATIONS: Treatment was clinical and uncontrolled, illness relatively severe, and statistical power limited. CONCLUSIONS: Early in BP-I disorder, risks of suicidal acts and accidents were high, inter-related, and associated with particular types of initial and later morbidity, suggesting some predictability and potential for preventive intervention.     

Suicidal ideation and suicide attempts among child and adolescent psychiatric inpatients in Finland

BACKGROUND: The aim was to study the prevalence of, and factors associated with, suicidal ideation and suicide attempts among child and adolescent inpatients during hospital treatment. METHODS: The target group included all the child and adolescent psychiatric inpatients (n=504) in Finland on a chosen day. Suicidality was determined by the psychiatrist responsible for the inpatient treatment, using a questionnaire also exploring demographic, diagnostic, and treatment characteristics, as well as traumatic events of the patient. RESULTS: The rate of suicidal ideation was 37.6%, and suicide attempts 10.8%. The factors independently associated with suicidal ideation in multivariate analysis were the following: being affected by open adult sexual behaviour (OR 3.2), having depression (OR 2.5) or conduct disorder (OR 2.4) diagnosis, and manifesting violent acts (OR 2.4). The factors independently associated with suicide attempts were: manifesting violent acts (OR 8.1), having depression diagnosis (OR 5.3), being affected by open adult sexual behaviour (OR 4.9), involuntary treatment (OR 4.7), and being of the female sex (OR 3.7). Suicidal ideation was particularly prevalent among boy patients having conduct disorders, manifesting violent acts, and belonging to the age group under 13 years old. Suicide attempts were particularly prevalent among depressive adolescent girl patients. LIMITATIONS: Suicidality was based solely on the clinician's evaluation. CONCLUSIONS: Suicidal ideation and suicide attempts are common among child and adolescent psychiatric inpatients. Particular attention should be directed to inpatients who manifest violent acts or have depressive disorder.     

Suicidal ideation and suicidal attempts in a population-based study of Chinese people: risk attributable to hopelessness, depression, and social factors

BACKGROUND: The population attributable fraction of hopelessness, depression and other risk factors for suicidal ideation and suicidal attempts in Asian population is unknown. Social support is often said to be a buffer against the effect of hopelessness and depression. METHODS: Suicidal ideation, suicidal attempts as well as demographic and psychometric data were delineated in a random and representative population sample of 2,219 Chinese people in Hong Kong. The population attributable fraction was used to determine the contribution of hopelessness, depression and other risk factors to suicidal ideation and attempts. RESULTS: Multivariate modelling shows that about 40% of suicidal ideation and attempts was attributable to depression and about 20% was attributable to hopelessness. Drug abuse and marital dissolution were also significant contributors to suicidality. The impact of hopelessness and depression was not affected by social support. LIMITATIONS: Suicidality was self-reported. CONCLUSIONS: Suicidal ideation and suicidal attempts were to a large extent attributable to depression and hopelessness, and, to a lesser extent, drug abuse and marital dissolution. Social support appeared to play little role as a buffer.     

Assessment of suicidality in a Moroccan metropolitan area

BACKGROUND: The aim of the study was to evaluate the prevalence of suicidal ideations and suicide attempts in a representative sample of the general population of the urban area of Casablanca, Morocco. METHODS: The survey was conducted based on face-to-face household interviews. The Mini International Neuropsychiatric Interview (M.I.N.I.) was used to assess axis I diagnoses according to DSM-IV criteria and the M.I.N.I. suicidality module to rate the severity of active suicidality. RESULTS: The 1-month prevalence of suicidal ideation was 6.3%. Seventeen subjects (2.1%) reported at least one suicide attempt during their lifetime. Some variables were positively associated to suicidal ideation: the non-married status, subjects with a history of psychiatric disorders, and subjects without children. At least one mental disorder was present among 88.2% of subjects with suicidal ideation. Major depressive disorder was the most prevalent one (23.5%). LIMITATIONS: The sample was small and the prevalence was not determined longitudinally. CONCLUSION: Suicidal ideation being relatively frequent in the general population, there is a need to develop programs of prevention of suicide.     

Suicidality in eating disorders: occurrence, correlates, and clinical implications

This review summarizes the published studies on suicide and suicide attempts in individuals with eating disorders, highlighting rates of occurrence, clinical correlates, and implications for practitioners. Multiple studies find high rates of suicide in patients with anorexia nervosa (AN) [Standardized Mortality Ratio (SMR) for suicide range from 1.0 to 5.3], whereas suicide rates do not appear to be elevated in bulimia nervosa (BN). In contrast, suicide attempts occur in approximately 3-20% of patients with anorexia nervosa and in 25-35% of patients with bulimia nervosa. Clinical correlates of suicidality in eating disorders include purging behaviors, depression, substance abuse, and a history of childhood physical and/or sexual abuse. Patients with eating disorders, particularly those with comorbid disorders, should be assessed routinely for suicidal ideation, regardless of the severity of eating disorder or depressive symptoms.     

Association of psychosis with suicidality in pediatric bipolar I, II and bipolar NOS patients

BACKGROUND: Psychosis in pediatric mood disorder patients may be related to suicidal ideation. Bipolar (BP) adolescents are at high risk of completed suicide. We examined whether pediatric BP patients with psychosis have a higher prevalence of suicidality than non-psychotic BP patients. Based on previous findings in adult BP patients, we predicted that pediatric BP patients with psychotic symptoms would have higher prevalence of suicidality, higher occurrence of lifetime psychiatric hospitalizations and worse current Global Assessment of Functioning Scale (GAF) scores compared to non-psychotic BP patients. METHODS: We studied 43 BP children and adolescents (mean age +/- S.D = 11.2 +/- 2.8 y, range = 8-17) who did (n = 17) or did not have (n = 26) a lifetime history of psychotic symptoms. Indicators of suicidality (thoughts of death and suicidal ideation, plans, and attempts), psychiatric diagnoses, psychotic symptoms, psychiatric hospitalizations and GAF scores were assessed with the K-SADS-PL interview. LIMITATIONS: Small sample size, cross-sectional study and exclusion of substance abuse comorbidity. RESULTS: Pediatric BP patients with a lifetime history of psychotic symptoms compared to BP patients without psychosis were more likely to have thoughts of death (100% versus 69.2%, p = 0.01), suicidal ideation (94.1% versus 42.3%, p = 0.001) and suicidal plans (64.7% versus 15.4%, p = 0.002). Occurrence of psychiatric hospitalization was higher in psychotic BP patients compared to non-psychotic BP patients (82.4% versus 46.2%, p = 0.018). CONCLUSIONS: Psychotic symptoms in pediatric BP patients are associated with suicidal ideation and plans, and psychiatric hospitalizations. Psychotic symptoms are a risk factor for suicidality amongst pediatric BP patients.     

Longitudinal trajectories and predictors of adolescent suicidal ideation and attempts following inpatient hospitalization

Remarkably little is known regarding the temporal course of adolescent suicidal ideation and behavior, the prediction of suicidal attempts from changes in suicidal ideation, or the prediction of suicidal attempts after accounting for suicidal ideation as a predictor. A sample of 143 adolescents 12-15 years old was assessed during psychiatric inpatient hospitalization and again at 3, 6, 9, 15, and 18 months postdischarge through a series of structured interviews and parent- and adolescent-reported instruments. Symptoms of depression, posttraumatic stress disorder, externalizing psychopathology, hopelessness, and engagement in several forms of self-injurious/suicidal behaviors (i.e., suicide threats/gestures, plans, nonsuicidal self-injury [NSSI]) were assessed. Latent growth curve analyses revealed a period of suicidal ideation remission between baseline and 6 months following discharge, as well as a subtle period of suicidal ideation reemergence between 9 and 18 months postdischarge. Changes in suicidal ideation predicted suicide attempts. After accounting for the effects of suicidal ideation, baseline suicide threats/gestures also predicted future suicide attempts. Higher adolescent-reported depressive symptoms, lower parent-reported externalizing symptoms, and higher frequencies of NSSI predicted weaker suicidal ideation remission slopes. Findings underscore the need for more longitudinal research on the course of adolescent suicidality.     

Impulsivity: differential relationship to depression and mania in bipolar disorder

INTRODUCTION: Impulsivity, a component of the initiation of action, may have a central role in the clinical biology of affective disorders. Impulsivity appears clearly to be related to mania. Despite its relationship to suicidal behavior, relationships between impulsivity and depression have been studied less than those with mania. Impulsivity is a complex construct, and it may be related differently to depression and to mania. METHODS: In subjects with bipolar disorder, we investigated impulsivity in relationship to affective symptoms. Trait-like impulsivity was assessed with the Barratt Impulsiveness Scale (BIS-11). Affective symptoms were measured using the Change version of the Schedule for Affective Disorders and Schizophrenia (SADS-C). Measures were compared using analysis of variance, multiple regression and factor analysis. RESULTS: Impulsivity, as measured by the BIS, was related differentially to measures of depression and mania. Total and attentional impulsivity correlated independently with depression and mania scores. Motor impulsivity correlated with mania scores, while nonplanning impulsivity correlated with depression scores. These relationships were strongest in subjects who had never met criteria for a substance use disorder. Among manic symptoms, visible hyperactivity correlated most strongly with BIS scores, regardless of clinical state. Among depressive symptoms, hopelessness, anhedonia, and suicidality correlated most strongly with BIS scores. CONCLUSIONS: Depression and mania are differentially related to impulsivity. Impulsivity is related more strongly to measures of activity or motivation than to depressive or manic affect. The relationship between impulsivity and hopelessness may be an important factor in risk for suicide.     

Clinical differences among depressed patients with and without a history of suicide attempts: findings from the STAR*D trial

BACKGROUND: This study sought to determine whether a history of suicide attempts among outpatients diagnosed with nonpsychotic major depressive disorder (MDD) is correlated with any difference in clinical presentation that should influence patient care. METHODS: Baseline data from the Sequenced Treatment Alternatives to Relieve Depression (STAR()D) trial on outpatients with MDD treated in primary and specialty care settings were used to model significant demographic and clinical correlates of suicide attempter status. RESULTS: Altogether, 16.5% of participants (n=667) reported prior suicide attempts. Controlling for age, gender, and depressive symptom severity, previous attempters had more current general medical conditions (micro=3.2 vs. 2.9, p<.0001), more current alcohol/substance abuse (p<.0001), and more work hours missed in the past week (26.2% vs. 18.2%, p<.0001) than non-attempters. On average, for the previously suicidal, the onset of MDD occurred 8.9 years earlier in life (p<.0001) and had included 1.2 additional depressive episodes (p=0.001) compared to those without prior suicidal behavior. Previous attempters also reported more current suicidal ideation (61.3% of previous attempters, adjusted OR 1.6, vs. 45.5% of nonattempters, p<.0001). LIMITATIONS: Presence or absence of a history of suicide attempts was determined only through self report. CONCLUSIONS: Those with a history of suicidal behavior suffer a greater burden of depressive illness. Earlier intervention and ongoing, aggressive care, including maintenance-phase pharmacotherapy, may be critical to mitigating the long-term consequences associated with this increased disease burden.     

Risk factors for suicidality in Europe: results from the ESEMED study

BACKGROUND: Precise knowledge of the epidemiology of suicidality provides necessary information for designing prevention programs. The aims of the present study were to investigate the prevalence and correlates of suicidal ideas and attempts in the general population of Europe. METHODS: The European Study on the Epidemiology of Mental Disorders (ESEMED) is a cross-sectional household survey carried out in a probability representative sample of non-institutionalised adults (aged 18 years or older) of six European countries (Belgium, France, Germany, Italy, the Netherlands and Spain). The Composite International Diagnostic Interview (CIDI 3.0) was administered to 21,425 individuals. RESULTS: Lifetime prevalence of suicidal ideation was 7.8% and of suicidal attempts 1.3%. Being women, younger and divorced or widowed were associated with a higher prevalence of suicide ideation and attempts. Psychiatric diagnoses were strongly related to suicidality. Among them, major depressive episode (Rate ratio 2.9 for lifetime ideas and 4.8 for lifetime attempts), dysthymia (RR 2.0 and 1.6), GAD (RR 1.8 and 2.3 for lifetime), PTSD (RR 1.9 and 2.0) and alcohol dependence (RR 1.7 and 2.5) were the most important. Population attributable risks for lifetime suicidal attempt was 28% for major depression. LIMITATIONS: Information about suicidal ideas and attempts was self reported, psychiatric diagnoses were made using fully structured lay interviews rather than clinician-administered interviews. CONCLUSIONS: In spite of meaningful country variation in prevalence, risk factors for suicidality are consistent in the European countries. Population prevention programmes should focus on early diagnosis and treatment of major depression and alcohol abuse and in those individuals with recent appearance of suicidal ideas.     

Are treatment emergent suicidality and decreased response to antidepressants in younger patients due to bipolar disorder being misdiagnosed as unipolar depression?

While antidepressants have been demonstrated to be a safe and effective treatment for unipolar major depressive disorder (MDD) in adults, the use of antidepressants to treat children and adolescents is controversial. There is a paucity of evidence to suggest that antidepressants are effective when used to treat children and adolescents and some recent placebo-controlled evidence has suggested that antidepressant treatment increases suicidality in this population. MDD is a very broad construct, and includes many clinical subtypes. Bipolar Disorder (BD) has an earlier age of onset than MDD. The initial polarity of illness in bipolar disorder is frequently depression. Patients are more likely to first present for treatment during the depressive phase of the illness than during manic or hypomanic phases. It is probable that a substantial portion of depressed children and adolescents may not suffer from unipolar MDD but may have a bipolar spectrum disorder. There are few trials supporting the efficacy of antidepressants in bipolar disorder, and some evidence that they may induce rapid cycling, switching and mania. Antidepressant induced mania is often mixed, with admixtures of manic and depressive features. An increased suicide risk is a particular feature of mixed states, potentially explaining why suicidal ideation can emerge with antidepressant treatment. Antidepressants are unlikely to somehow act differently in children than they do in adults. A more plausible explanation is that incipient bipolar disorder is often not diagnosed early in children and adolescents and the differential effects of antidepressants in this group is a result of differing diagnostic casemixes.     

Are body dissatisfaction, eating disturbance, and body mass index predictors of suicidal behavior in adolescents? A longitudinal study

Disordered eating, body dissatisfaction, and obesity have been associated cross sectionally with suicidal behavior in adolescents. To determine the extent to which these variables predicted suicidal ideation and attempts, the authors examined these relationships in a longitudinal design. The study population included 2,516 older adolescents and young adults who completed surveys for Project EAT-II (Time 2), a 5-year follow-up study of adolescents who had taken part in Project EAT (Time 1). Odds ratios for suicidal behaviors at Time 2 were estimated with multiple logistic regression. Predictor variables included Time 1 extreme and unhealthy weight control behaviors (EWCB and UWCB), body dissatisfaction, and body mass index percentile. Suicidal ideation was reported by 15.2% of young men and 21.6% of young women, and suicide attempts were reported by 3.5% of young men and 8.7% of young women. For young women, suicidal ideation at Time 2 was predicted by Time 1 EWCB. The odds ratio for suicide attempts was similarly elevated in young women who had reported EWCB at Time 1. These odds ratios for both suicidal ideation and suicide attempts remained elevated even after controlling for Time 2 depressive symptoms. In young men, EWCB was not associated with suicidal ideation or suicide attempts 5 years later. Body mass index and body dissatisfaction did not predict suicidal ideation or suicide attempts in young men or young women. These results emphasize the importance of EWCB.     

Sleep and adolescent suicidal behavior

STUDY OBJECTIVES: Suicide risk begins to increase during adolescence. Adolescents do not get enough sleep and are also at risk for many sleep disturbances. This study examined the association between sleep patterns and sleep problems and adolescent suicidal behavior. DESIGN AND SETTING: A questionnaire survey of adolescents attending school was conducted in one prefecture of Shandong Province, People's Republic of China. PARTICIPANTS: A total of 1,362 adolescents attending school (mean age 14.6 years, 60% males) participated in the survey. MEASUREMENTS: Respondents completed a self-administered questionnaire that asked about sleep patterns, sleep problems, suicidal behavior, depressive symptoms, and demographic characteristics of the family and adolescent. RESULTS: Overall, 19.3% of the sample reported having suicidal ideation, 10.5% having suicide attempts in the past 6 months, 16.9% having insomnia symptoms, 2.3% having taken hypnotic medication, and 48.9% having experience of nightmares in the past month. Mean night sleep duration was 7.6 hours (SD = 0.8). Logistic regression analyses showed that sleeping less than 8 hours at night (OR = 2.89, 95% confidence interval [CI] = 1.07-7.81) and frequent nightmares (OR = 2.43, 95% CI = 1.76-3.35) were significantly associated with increased risk for suicide attempts after adjustment for age, sex, father's occupation, and depressive symptoms and that nightmares (OR = 1.69, 95% CI = 1.20-2.38) were also significantly related to suicidal ideation. CONCLUSION: These findings demonstrate the association between short sleep duration and nightmares and suicidal behavior and highlight the potential role of sleep intervention in the prevention of adolescent suicide.     

Use of olanzapine in dysphoric mania

BACKGROUND: The simultaneous presentation of both manic and depressive symptoms has long been recognized. Nevertheless, a variable prevalence of dysphoric mania has been reported. The aim of this study was to estimate the prevalence of dysphoric mania among hospitalized patients and to assess the effectiveness of olanzapine in this type of patients. METHODS: Eighty-six patients who met DSM-IV criteria for mania were evaluated at admission with a protocol that included McElroy's criteria for dysphoric mania [Am. J. Psychiatry 149 (1992) 1633]. Treatment was administered according to clinical need, using mood stabilizers combined with antipsychotics. Sequential assessments were conducted throughout the study. RESULTS: Forty-four patients (51.2%) fulfilled McElroy's criteria for dysphoric mania. Fourteen of these dysphoric patients were treated with olanzapine in combination with mood-stabilizers. All patients improved in manic symptoms but patients treated with olanzapine improved significantly more than those treated with other antipsychotics in depressive symptoms. LIMITATIONS: The lack of randomization is a methodological limitation of this study, so these findings should be considered as preliminary. CONCLUSIONS: Dysphoric symptoms are common in this population of manic patients. Olanzapine in combination with mood-stabilizers may be effective in these patients. Additional controlled studies are needed to replicate these results.

Natural history of suicidal behaviors in a population-based sample of young adults

BACKGROUND: Suicidal behaviors in young individuals represent an important public health problem. Understanding their natural history and relationships would therefore be of clinical and research value. In this study, we examined the natural histories of several suicidal behaviors and investigated two conceptual models of suicidality (dimensional and categorical) in the context of adolescent and adult-onset suicide attempts. METHOD: Participants were members of a prospectively studied, representative, population-based school cohort followed since age 6 (n = 3017) through mid-adolescence (n = 1715) to their early twenties (n = 1684). Outcome measures included suicidal ideation, attempts and completions. RESULTS: Approximately one in 500 individuals died by suicide. About 33% had suicidal ideas and 9.3% made at least one suicide attempt. Over half (4.9%) of the self-reported attempters made their first attempt before age 18. With the exception of current suicidal ideas, non-fatal suicidal behaviors were more prevalent in females. In general, parental and cross-sectional self-reports underestimated suicidality rates. Aikaike (AIC) and Bayesian (BIC) information criteria suggested the ordinal model, and dimensional conceptualization of suicide attempts of different onset age, to be more optimal than its multinomial/categorical counterpart (ordinal: AIC 567.55, BIC 635.67; multinomial: AIC 616.59, BIC 723.83). Both models, nevertheless, identified five common factors of relevance to suicidal diathesis: gender, disruptive disorders, childhood anxiousness and abuse, and suicidal thoughts. CONCLUSIONS: Non-fatal suicidal behaviors in adolescents and young adults are more common than suggested by cross-sectional studies and parental reports. The dimensional model may be more useful in explaining the relationship of suicide attempts of different age of onset.     

Suicidality after traumatic brain injury: demographic,injury and clinical correlates

BACKGROUND: In spite of the high frequency of emotional distress after traumatic brain injury (TBI), few investigations have examined the extreme of such distress, namely, suicidality, and no large scale surveys have been conducted. The current study examined both the prevalence and demographic, injury, and clinical correlates of hopelessness, suicidal ideation and suicide attempts after TBI. METHODS: Out-patients (N = 172) with TBI were screened for suicidal ideation and hopelessness using the Beck Scale for Suicide Ideation and the Beck Hopelessness Scale. Data were also collected on demographic, injury, pre-morbid and post-injury psychosocial variables and included known risk factors for suicide. RESULTS: A substantial proportion of participants had clinically significant levels of hopelessness (35%) and suicide ideation (23%), and 18% had made a suicide attempt post-injury. There was a high degree of co-morbidity between suicide attempts and emotional/psychiatric disturbance. Results from regression analyses indicated that a high level of hopelessness was the most significant association of suicide ideation and a high level of suicide ideation, along with occurrence of post-injury emotional/psychiatric disturbance, were the most significant associations of post-injury suicide attempts. Neither injury severity nor the presence of pre-morbid suicide risk factors contributed to elevated levels of suicidality post-injury. CONCLUSIONS: Suicidality is a common psychological reaction to TBI among out-patient populations. Management should involve careful history taking of previous post-injury suicidal behaviour, assessment of post-injury adjustment to TBI with particular focus on the degree of emotional/psychiatric disturbance, and close monitoring of those individuals with high levels of hopelessness and suicide ideation.     

Suicidal Behavior,Depression, and Hopelessness in Child Psychiatric Inpatients: A Replication and Extension

Examination of 55 consecutively admitted 6-to 13-year-old psychiatric inpatients indicated that 58% reported suicidal ideation and 40% had attempted suicide. Suicidal ideation was significantly associated with self-reports of hopelessness. Suicide attempts were significantly associated with both hopelessness and a diagnosis of depressive disorder, particularly major depression. Hopelessness and depression were highly correlated, and associations between Suicide attempts, hopelessness, and depression were accounted for partly by a group of hopeless depressed children. Thirty-six percent of suicide attempters had made prior attempts. This group of repeat attempters were older and had the highest rate of depressive disorders (75%). Whereas older (11- to 13-year-old) children tended to contemplate and attempt the same method, younger children tended to think of one method and attempt another, usually less lethal, method.
