Correlates of suicidal ideation in dysphoric mania

BACKGROUND: Previous investigations have reported that suicidal ideation and behavior are more prevalent during mixed than pure mania. Uncertainties exist about whether suicidality in mania arises from multiple concurrent depressive symptoms, or rather, as a categorical phenomenon, reflecting dysphoria without necessarily a full major depression. To elucidate the relationship between suicidal ideation and dysphoric mania, we analyzed clinical and demographic features associated with suicidal versus nonsuicidal dysphoric manic inpatients. METHODS: Records were reviewed for 100 DSM-III-R bipolar I manic inpatients at the Payne Whitney Clinic of New York Hospital from 1991-1995. All had > or = 2 concomitant depressive symptoms (other than suicidality). Affective and psychotic symptoms, past suicide attempts, prior illness, and related clinical/demographic variables were assessed by a standardized protocol. RESULTS: Suicidal ideation was significantly more common among dysphoric manics who were caucasian, took antidepressant medications in the week prior to admission, had histories of alcohol abuse/dependence, and made past suicide attempts. Suicidal ideation was evident for nearly half of dysphoric manic patients with < or = 3 depressive symptoms who did not meet DSM criteria for a mixed state. No individual manic or depressive symptoms other than dysphoric mood were more common among suicidal than nonsuicidal patients. LIMITATIONS: Findings from this retrospective study require confirmation using a prospective assessment. Treatments were naturalistic and may have differentially influenced hospital course and illness characteristics. Factors related to suicide attempts (rare in this cohort) or completions (not a focus of this study) may differ from those related only to suicidal ideation. CONCLUSIONS: Caucasian dysphoric manic patients with past suicide attempts and substance abuse may have a significantly elevated risk for suicidality, even when full major depression does not accompany mania. Suicidality is a clinically important consideration in a majority of dysphoric manic patients.     

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 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.

目的:了解北京地区综合医院住院病人自杀意念、自杀未遂的出现率及其危险因素。方法:采用自制抑郁筛选量表在随机抽取的北京40家各级综合医院中调查了2914例年龄>15岁的住院病人,了解他们自杀意念、自杀未遂发生情况及相关因素,并通过多因素logistic模型发现其危险因素。结果:2914例患者中,187人(6·42%;95%CI为5·58%~7·64%)有过自杀意念,其危险因素排列为:近一年感到绝望的频率高(OR=9·2,95%CI为6·5~12·9)、亲属有过自杀行为(4·3,2·3~8·3)、调查当时有重性抑郁发作(2·7,1·7~4·3)、熟人有过自杀行为(2·0,1·3~2·9)、年龄<55岁(1·7,1·2~2·3)、女性(1·5,1·1~2·1)。2914例患者中,25人(0·86%;95%CI为0·56%~1·26%)有过自杀未遂,其危险因素排列为:目前有重性抑郁发作(OR=5·6,95%CI为2·1~15·1)、亲属有过自杀行为(5·1,1·4~18·9)、近一年感到绝望频率高(4·7,1·9~11·9)、年龄<55岁(3·6,1·4~9·3)、女性(3·6,1·4~9·3)。结论:伴有抑郁症状的综合医院住院病人应视为自杀高危人群,需投入更多的关注。根据其自杀意念、自杀未遂的危险因素,应在综合医院制定和执行有针对性的自杀预防计划。     

Diagnostic outcome of adolescent self-reported suicidal ideation at 8-year follow-up

BACKGROUND: There are few epidemiological data on the outcome of adolescent self-reported suicidal ideation. METHOD: Data from an epidemiological study were used to examine self-reported suicidal ideation in adolescence as a predictor of suicidal ideation and psychiatric diagnoses at 8-year follow-up. RESULTS: Suicidal ideation was reported by 41 (4.5%) of 912 adolescents aged 11-18 and by 19 (2.5%) of 795 young adults aged 19-26. Most parents of adolescents with positive self-report did not report suicidal ideation in their child. Suicidal ideation in adolescents and young adults was associated with other psychiatric problems. Adolescent self-reported suicidal ideation was not a predictor of suicidal ideation or any major psychiatric disorder 8 years later. In males, suicidal ideation in adolescence was associated with specific phobia at follow-up. LIMITATIONS: The sample of adolescents may not be representative of the general population. There were no outcome measures other than DSM-IV diagnoses. Suicidal ideation was assessed by only one item, both at baseline and follow-up. CONCLUSIONS: Adolescents and young adults with self-reported suicidal ideation had high rates of psychiatric problems. Adolescent self-reported suicidal ideation did not predict suicidal ideation or any major psychiatric disorders (i.e. depressive disorders, substance use disorders, or psychotic disorders) at follow-up.     

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.     

Suicidal behaviour among primary-care patients with depressive disorders

BACKGROUND: Most national suicide prevention strategies set improved detection and management of depression in primary health care into a central position. However, suicidal behaviour among primary-care patients with depressive disorders has been seldom investigated. METHOD: In the Vantaa Primary Care Depression Study, a total of 1119 primary-care patients in the City of Vantaa, Finland, aged 20 to 69 years, were screened for depression with the Primary Care Evaluation of Mental Disorders (PRIME-MD) questionnaire. Depressive disorders were diagnosed with the Structured Clinical Interview for DSM-IV Axis I Disorders (SCID-I), and the 137 patients with depressive disorder were included in the study. Suicidal behaviour was investigated cross-sectionally and retrospectively in three time-frames: current, current depressive episode, and lifetime. Current suicidal ideation was measured with the Scale for Suicidal Ideation (SSI), and previous ideation and suicide attempts were evaluated based on interviews plus medical and psychiatric records. RESULTS: Within their lifetimes, 37% (51/137) of the patients had seriously considered suicide and 17% (23/137) attempted it. Lifetime suicidal behaviour was independently and strongly predicted by psychiatric treatment history and co-morbid personality disorder, and suicidal behaviour within the current episode was predicted most effectively by severity of depression. CONCLUSIONS: Based on these findings and their convergence with studies of completed suicides, prevention of suicidal behaviour in primary care should probably focus more on high-risk subgroups of depressed patients, including those with moderate to severe major depressive disorder, personality disorder or a history of psychiatric care. Recognition of suicidal behaviour should be improved. The complex psychopathology of these patients in primary care needs to be considered in targeting preventive efforts.     

广州市精神病医院50年住院病人自杀危险因素的病例对照研究

目的:识别精神分裂症住院病人自杀的潜在危险因素,为探讨如何进一步预防住院精神病人的自杀提供依据。方法:对广州市精神病医院1956-2005年住院精神病人自杀进行回顾性分析,并对其中的精神分裂症病人按同性别、同诊断、相同或相近年龄、住院进行1:1匹配的病例对照研究。结果:共有77例住院精神病人发生自杀,自杀发生率为133.1/10万(95%CI103.4-162.85/10万)。多数自杀者为精神分裂症病人(64例,占83.1%),多数自杀者采取自缢的方式(59例,占76.6%),多数病人的自杀行为发生在病房内(52例,占67.5%);自杀组的住院次数明显高于对照组(2.13±1.89/1.23±0.75,P=0.001);自杀组本次住院前1月及住院期间的自杀未遂次数明显高于对照组(0.39±0.85/0.09±0.39,0.59±1.52/0.00±0.00,P=0.017,0.003)。自杀组有罪恶观念、心境抑郁者多于对照组(18.8%/3.1%,28.1%/6.3%,P=0.006,0.004);住院精神分裂症病人的罪恶观念、心境抑郁、本次住院前1月有自杀意念和自杀未遂是其自杀行为发生的危险因素(β=2.407、1.566、1.201、1.643)。结论:该院50年住院病人的自杀发生率与国外近似,精神分裂症病人自杀的危险因素是罪恶观念、心境抑郁、住院前1月自杀意念和自杀未遂。     

Suicidal Ideation in Adolescent Psychiatric Inpatients as Associated With Depression and Attachment Relationships

Examined suicidal ideation in adolescent psychiatric inpatients as associated with depressive symptoms and attachment to mother, father, and peers. Fifty-nine adolescent psychiatric inpatients (25 male, 34 female) completed self-report measures of suicidal ideation, depressive symptoms, and attachment. Attachment to mother accounted for significant variation in levels of depressive symptoms and suicidal ideation. In addition, attachment to peers accounted for significant variation in suicidal ideation and girls' (but not boys') depressive symptoms. However, after adjusting for depressive symptoms, attachment variables failed to contribute additional variance in suicidal ideation. Self-reported depressive symptomatology remained the strongest predictor of suicidal ideation, regardless of its order in the regression analyses. Prevention and treatment efforts may focus on mother-adolescent attachment and peer attachment (particularly in girls) to reduce risk for depression and suicidal ideation.     

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.     

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.     

Detecting suicidal ideation in older patients: identifying risk factors within the general practice setting

BACKGROUND: GPs are the most frequently accessed health professional among suicidal individuals in the community.AIM: To determine the prevalence of psychological distress and suicidal ideation among patients aged 60 years and older presenting to GPs, and the relationship between these variables in detecting patients who may be contemplating suicide.Design of study: Cross-sectional analysis of older patients presenting to Australian GPs between 2002 and 2003. SETTING: One thousand and sixty-one consecutive patients aged 60 years or over attending one of 54 randomly selected Western Australian GPs. METHOD: Prior to their medical consultation, patients completed a self-report questionnaire, which included questions about current suicidal ideation (Depressive Symptom Inventory Suicidality Subscale [DSI-SS]) and depression (Center for Epidemiological Studies Depression Scale [CES-D]). Patients' chief complaints were obtained from consultation summary sheets completed by their GP. RESULTS: Although only 5.1% of patients presented with psychological complaints, 5.8% acknowledged current suicidal ideation and 23.8% had clinically significant levels of depressive symptomatology. Suicidal ideation was associated with CES-D scores greater than 16 (odds ratio [OR] = 3.7, 95% confidence interval [CI] = 1.5 to 8.9), feelings of depression (OR = 7.7, 95% CI = 3.4 to 17.7), and previous suicide attempt (OR = 7.4, 95% CI = 2.7 to 20.2) in a logistic regression model, but not with poor self-perceived health, use of licit drugs (smoking, alcohol, and hypnotics), or type of presenting complaint at the time of assessment. CONCLUSIONS: Although older general practice patients tend to present for issues related to their physical health, approximately a quarter of this cohort also possess high levels of psychological distress, including current thoughts of suicide. Older patients who show any signs of depression or distress should be asked about psychological symptoms, including suicidal ideation.     

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.     

Incidence of suicide ideation and attempts in adults: the 13-year follow-up of a community sample in Baltimore, Maryland.

BACKGROUND: Utilizing a prospectively designed community sample, we set out to estimate the rate of newly-incident suicidal ideation and attempts (non-fatal suicide behaviour) in a community sample, to evaluate antecedent sociodemographic characteristics and psychiatric disorders, and to assess use of mental health services in relation to non-fatal suicide behaviour. METHOD: Prospectively-gathered data was utilized from 3481 continuing participants in the 13-year follow-up of the Baltimore sample of the NIMH Epidemiologic Catchment Area survey interviewed in 1981, 1982 and 1993/6. RESULTS: The incidence of suicide attempts was estimated at 148.8 per 100,000 person-years and ideation at 419.9 per 100,000 person-years. Persons in the youngest age group, in the lowest socioeconomic status, and previously married persons were at increased risk for non-fatal suicide behaviour during the follow-up interval. Persons who reported suicidal ideation at baseline were more likely to report having attempted suicide at follow-up (RR = 6.09, 95% CI 2.58-14.36). Psychiatric disorders, especially depression and substance abuse, were associated with new-onset of non-fatal suicidal behaviour. While persons who reported newly-incident suicidal behaviour were more likely to report use of mental health services, few said that suicidal ideation or attempts were the reason for the visits. CONCLUSIONS: Suicidal ideation is a common and important antecedent to suicide attempts and deserves more attention in community and general medical settings.     

Suicidal behaviour in adolescence and subsequent mental health outcomes in young adulthood

BACKGROUND: The aim of this study was to examine the linkages between suicidal ideation and attempt in adolescence and subsequent suicidal behaviours and mental health in young adulthood. METHOD: Data were gathered during the course of a 25-year longitudinal study of a birth cohort of 1265 New Zealand children. The information collected included: (a) measures of suicidal thoughts and attempts in adolescence (< 18 years); (b) measures of suicidal ideation, suicide attempt, major depression, anxiety disorders, and substance use disorders in young adulthood (18-25 years); and (c) measures of childhood and family background, individual characteristics, and mental disorders in adolescence. RESULTS: After statistical adjustment for confounding factors, suicide attempt in adolescence was associated with increased risks of subsequent suicidal ideation (OR 5.7) suicide attempt (OR 17.8) and major depression (OR 1.5). Those reporting suicidal ideation without suicide attempt showed moderate increases in risks of later suicidal ideation (OR 2.5), suicide attempt (OR 2.0) and major depression (OR 1.6). In addition, there was evidence of an interactive relationship in which suicidal behaviour in adolescence was associated with increased risks of later substance use disorders in females but not males. CONCLUSIONS: Young people reporting suicidal ideation or making a suicide attempt are an at-risk population for subsequent suicidal behaviour and depression. Further research is needed into the reasons for suicidal adolescent females being at greater risk of later substance use disorder.     

An analysis of adolescent suicide attempts: the expendable child

Assessed the concept of the "expendable child" syndrome proposed by Sabbath (1969) as a contributing factor in adolescent suicide attempts. It was hypothesized that suicidal adolescents would be rated higher on a measure of "expendability" than would a psychiatric control group of adolescents with no known history of suicide attempts or ideation. Forty adolescents, ages 13-24, who had been seen in psychotherapy at a teen-age health clinic, were rated by their psychotherapists on suicidality and a 12-item scale of expendability (a sense of being unwanted and/or a burden on the family). As predicted, suicidal adolescents received significantly higher ratings on the expendability measure than nonsuicidal adolescents. Results support the concept that feeling expendable is a characteristic of suicidal adolescents. Implications for prevention and treatment of adolescent suicidality are discussed.     

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.     

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.
