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.     

Personality traits as correlates of suicide attempts and suicidal ideation in young adults

BACKGROUND: Adults in their twenties appear to be at high risk for suicidal behaviors (SBs) and there is substantial evidence suggesting that certain personality traits may increase individual vulnerability to suicide. METHOD: We investigated relationships of personality traits with two SBs in a cohort (n=1140) of 21- to 24-year-old adults, representative of the general population of Quebec. Subjects were assessed using a series of structured diagnostic and personality trait questionnaires. Multivariate logistic regression analyses were employed to identify personality trait correlates of suicide-attempt history and serious suicidal ideation in the context of other known risk factors, such as psychopathology and experiences of childhood sexual and physical abuse. RESULTS: Traits of conduct problems contributed to both suicide attempts [odds ratio (OR) 1.03, 95% confidence interval (CI) 1.01-1.06] and suicidal ideation (OR 1.04, 95% CI 1.02-1.07), while identity problems (OR 1.10, 95% CI 1.07-1.13) and gender-moderated impulsivity contributed exclusively to suicidal ideation. CONCLUSIONS: Personality traits may make independent contributions to current suicidal ideation and previous suicide attempts in certain subgroups of suicidal individuals. In order to further explore their utility as markers of suicide risk and targets of intervention further investigation in clinical samples and other cultural and age groups is necessary.     

Adverse childhood experiences and lifetime suicide ideation: a cross-sectional study in a non-psychiatric hospital setting

We have assessed the effect of adverse childhood experiences on the lifetime prevalence of suicide ideation in a cross-sectional study involving 182 patients aged 18 to 44 years, consecutive attenders at an A&E review clinic. All participants were interviewed by a psychologist using standardised questionnaire instruments addressing participants' demographic characteristics, drug use, depressed mood, eight major categories of adverse childhood experiences (including physical, emotional and sexual abuse) and suicide ideation. The response rate was 73%. In multivariate logistic regression analyses, those with a history of two or more forms of childhood adversity relative to those with none were at increased risk of depressed mood (OR = 5.5, 95% CI = 2.3-13.3) and suicide ideation (OR = 3.5, 95% CI = 1.5-8.3). The findings emphasise the need to set suicide prevention within the broader context of society's obligation to protect children from physical, emotional and sexual abuse.     

Family history of suicidal behavior and early traumatic experiences: additive effect on suicidality and course of bipolar illness?

BACKGROUND: Bipolar disorder (BD) is associated with a high prevalence of suicide attempt and completion. Family history of suicidal behavior and personal history of childhood abuse are reported risk factors for suicide among BD subjects. METHODS: BD individuals with family history of suicidal behavior and personal history of childhood abuse (BD-BOTH), BD individuals with family history of suicidal behavior or personal history of childhood abuse (BD-ONE), and BD individuals with neither of these two risk factors (BD-NONE) were compared with regard to demographic variables and clinical measures. RESULTS: Almost 70% of the sample had a history of a previous suicide attempt. There were significantly higher rates of previous suicide attempts in the BD-BOTH and BD-ONE relative to the BD-NONE group. BD-BOTH were significantly younger at the time of their first suicide attempt and had higher number of suicide attempts compared with BD-NONE. BD-BOTH were significantly younger at the time of their first episode of mood disorder and first psychiatric hospitalization and had significantly higher rates of substance use and borderline personality disorders compared to BD-NONE. LIMITATIONS: Retrospective study. Use of semi-structured interview for the assessment of risk factors. CONCLUSIONS: BD individuals with a familial liability for suicidal behavior and exposed to physical and/or sexual abuse during childhood are at a greater risk to have a more impaired course of bipolar illness and greater suicidality compared to those subjects with either only one or none of these risk factors. Prospective studies are needed to confirm these findings.     

Risk factors and life processes associated with the onset of suicidal behaviour during adolescence and early adulthood

BACKGROUND: This study examined associations between childhood circumstances, adolescent mental health and life events, and the development of suicidal behaviour in young people aged between 15 and 21 years. METHOD: Data were gathered over the course of a 21-year longitudinal study of a birth cohort of 1265 children born in New Zealand. The measures collected included: (1) patterns of suicidal behaviour (ideation, attempt) (15-21 years); (2) social background, family functioning, parental and individual adjustment during childhood (0-16 years); and (3) time dynamics of mental health and stressful life events during adolescence and early adulthood (15-21 years). RESULTS: By the age of 21 years, 28.8% of the sample reported having thought about killing themselves and 7.5% reported having made a suicide attempt. The childhood profile of those at greatest risk of suicidal behaviour was that of a young person reared in a family environment characterized by socio-economic adversity, marital disruption, poor parent-child attachment and exposure to sexual abuse, and who as a young adolescent showed high rates of neuroticism and novelty seeking. With the exception of the socio-economic and personality measures, the effects of childhood factors were largely mediated by mental health problems and exposure to stressful life events during adolescence and early adulthood. Mental health problems including depression, anxiety disorders, substance use disorder, and to some extent conduct disorder, in addition to exposure to adverse life events, were significantly associated with the onset of suicidal behaviours. CONCLUSIONS: Findings support a life course model of the aetiology of suicidal behaviour in which risk of developing suicidal behaviour depends on accumulative exposure to a series of social, family, personality and mental health factors.     

Early sexual abuse and lifetime psychopathology: a co-twin-control study

BACKGROUND: This study was designed to determine lifetime prevalence of psychiatric disorders among twins who reported childhood sexual abuse (CSA), and to compare these rates with those among non-abused co-twins. The contribution of familial and individual-specific factors to reported sexual abuse was also examined. METHOD: Information about lifetime psychopathology and substance use was obtained by structured telephone interviews with 5995 Australian twins. Twins who reported a history of childhood sexual abuse (CSA) were contrasted on lifetime psychopathology with subjects without such a history; in addition, comparisons were made between same-sex twin pairs discordant for CSA. RESULTS: A history of CSA was reported by 5.9% of the women and 2.5% of the men. In the sample as a whole, those reporting CSA were more likely to receive lifetime diagnoses of major depression, conduct disorder, panic disorder and alcoholism, and were more likely to report suicidal ideation and a history of suicide attempt. Abused women, but not men, were also more likely to report social phobia. When comparisons were restricted to non-abused co-twins, no differences in psychopathology were seen. However, rates of major depression, conduct disorder and suicidal ideation were higher if both co-twins were abused than if the respondent alone reported CSA. Model-fitting indicated that shared environmental factors influenced risk for reported CSA in women, but not in men. CONCLUSION: The association between CSA and psychopathology arises at least in part through the influence of shared familial factors on both risk of victimization and risk of psychopathology.     

Predictors of Continued Suicidal Behavior in Adolescents Following a Suicide Attempt

Describes adolescents who attempt suicide and their risk for ongoing suicidal behavior. Fifty-eight adolescents (53 female) who attempted suicide received a baseline evaluation that was analyzed to identify factors that were associated with continued suicidal ideation and reattempt. At a 3-month follow-up assessment, 45% reported continued suicidal ideation and 12% reported a repeat attempt. Baseline measures of family functioning, feelings of hopelessness, and abilities to regulate affect were associated with suicidal ideation at follow-up but not as strongly as depressed mood. After controlling for depressive symptoms, the association between family functioning and continued suicidal behavior was no longer significant. Depressed mood at baseline was most strongly associated with both continued suicidal ideation and reattempt.     

Childhood adversities and risk for suicidal ideation and attempts: a longitudinal population-based study

BACKGROUND: Developmental adversities may be risk factors for adult suicidal behavior, but this relationship has rarely been studied prospectively. The present study examined the association between childhood adversities and new onset suicidal ideation and attempts in an adult population-based sample. METHOD: The study used a large community mental health survey (the Netherlands Mental Health Survey and Incidence Study; n=7076, age range 18-64 years). Logistic regression analyses were used to evaluate the relationship between childhood adversities and new onset of suicidal ideation and attempts over 3 years of longitudinal follow-up. RESULTS: During the study period 85 new cases of suicidal ideation and 39 new onset suicide attempts were observed. The incidence rate for new suicide ideation was 0.67% per year and the incidence rate for new suicide attempts was 0.28% per year. Childhood neglect, psychological abuse and physical abuse were strongly associated with new onset suicidal ideation and suicide attempts. Odds ratios (ORs) ranged from 2.80 to 4.66 for new onset suicidal ideation and from 3.60 to 5.43 for new onset suicide attempts. The total number of adversities reported had a strong graded relationship to new onset suicidal ideation and attempts. These associations remained significant after controlling for the effects of mental disorders. CONCLUSIONS: Childhood abuse and multiple adversities are strongly associated with future suicidal behavior and the mental disorders assessed in the present study do not fully account for this effect. A comprehensive understanding of suicidal behavior must take childhood adversities into account.

Psychomotor retardation in elderly depressed patients

BACKGROUND: Up to 70% of older people who commit suicide consult a general practitioner (GP) in the month prior to their death. The purpose of this study was to identify the clinical and demographic characteristics of older adults who are contemplating suicide and are in contact with a GP. METHODS: We utilised a cross-sectional study to investigate the association between suicidal ideation and clinical/demographic variables of 504 consecutive patients aged 60 years or over, attending 1 of 54 randomly selected Western Australian GPs. Prior to their medical consultation, patients completed a self-report questionnaire, which included questions about suicidal ideation (Depressive Symptom Inventory-Suicidality Subscale, DSI-SS), demographic factors, lifestyle factors, physical health and mental health, including depression (Center for Epidemiologic Studies-Depression Scale, CES-D). RESULTS: Within our sample of older patients, 6.3% acknowledged current suicidal ideation. Multivariate analyses indicated that current suicidal ideation was strongly associated with being depressed at least occasionally during the previous week (OR=7.3, 95% CI=2.3-23.0), CES-D scores of 16 points or greater (OR=3.6, 95% CI=1.0-12.1), and a prior history of attempted suicide (OR=15.5, 95% CI=4.0-60.6). Limitations: Our results and conclusions are limited to suicidal ideation, and may not apply to suicidal behaviour. CONCLUSIONS: Depressive symptomatology is strongly associated with suicidal ideation in later life. Strategies that enhance GPs' identification and treatment of affective illness in older patients should have the greatest impact on suicide rates within this age group.     

The influence of media reporting of a celebrity suicide on suicidal behavior in patients with a history of depressive disorder

BACKGROUND: Few studies have directly assessed the impact of a specific media report in vulnerable people. This study investigates possible influences of media reporting of a celebrity suicide on subsequent suicidal behaviors and associated risk factors among depressive patients. METHODS: Depressive patients (N=461) were assessed through a structured interview soon after extensive media reporting of a celebrity suicide. RESULTS: Among 438 depressive patients exposed to the media report, 38.8% reported an influence on subsequent suicidal behaviors, including 24 (5.5%) with a suicide attempt. The risk of such influence was highest among patients in a severe depressive state just prior to the media report (adjusted OR 7.81, 95% CI 3.28-18.59). Such influence on a subsequent suicide attempt was highest in patients with a most recent suicide attempt within one month prior to the media reports (adjusted hazard ratio 11.91, 95% CI 3.76-37.72). LIMITATIONS: Our finding of the significant media influence may reflect adverse thoughts among more suicidal and depressed individuals. The possible influence of other factors on the findings cannot be ruled out. CONCLUSIONS: This study has provided more convincing evidence suggesting negative influences of media reporting of a celebrity suicide on subsequent suicidal behaviors among depressive patients. Particular attention in terms of potential negative media influences should be paid to patients who are younger and currently depressed and have made a recent suicide attempt.     

Suicidal Ideation and Attempted Suicide Among Women Living With HIV/AIDS

The prevalence, timing, and predictors of suicidal ideation and attempted suicide were evaluated in a sample of 207 HIV-positive women in New York City. Twenty-six percent of the women reported attempting suicide since their HIV diagnosis. Of those who made an attempt, 42% acted within the first month after diagnosis and 27% acted within the first week. AIDS diagnosis, psychiatric symptoms, and physical or sexual abuse were significant positive predictors of both suicidal ideation and attempts. Contrary to expectations, having children and being employed were also significant positive predictors. Spirituality was significantly negatively associated with suicidal ideation only. These results suggest that suicide prevention measures should be implemented for HIV-positive women immediately after diagnosis. Specifically, interventions should target those with an AIDS diagnosis, psychiatric symptoms, an abuse history, children, or employment. The encouragement of spiritual connection seems to be a deterrent to suicidal thoughts and is a possible avenue for intervention.     

Non-consensual sex experienced by men who have sex with men: prevalence and association with mental health

Little is known about the psychosocial factors associated with sexual assault experienced by males. Men (N=358), 19-35 years of age, recruited by community outreach, completed questionnaires. Eligibility criteria included: being HIV-negative and self-identifying as gay or bisexual. Lifetime prevalence rates of childhood sexual abuse, juvenile prostitution, and adult sexual assault were determined. The mental health of this population was explored including associations between sexual victimization and mental health disorders (alcohol abuse, suicidal ideation and attempts, mood disorders, and poor self-esteem). Almost 1 in 10 of the men had engaged in juvenile prostitution, 14% were forced into sexual activity before 14 years of age, and 14% were sexually victimized after the age of 14. Those exposed to non-consensual sex were 2.9 (95% CI: 1.8-4.7) times more likely to abuse alcohol than those free of victimization. Those who reported childhood sexual abuse were 3.3 (95% CI: 1.7-6.4) times more likely to have attempted suicide. Juvenile prostitution was associated with current depression (OR=6.4; 95% CI: 2.8-14.9). Health professionals have the responsibility to respond competently and sensitively to victims of sexual violence. To do this, many need to recognize the prevalence of male sexual trauma, to deconstruct their personal beliefs about same-sex sexual violence, and to learn to ask sensitive questions in their assessment interviews.     

Psychopathology, childhood sexual abuse and other childhood adversities: relative links to subsequent suicidal behaviour in the US

BACKGROUND: Research shows that psychopathology, child sexual abuse and other childhood adversities are risk factors for suicide. However, few have investigated their joint and independent roles in the pursuit of a reliable, predictive model of suicidal behaviour. METHODS: Data are from the National Comorbidity Survey (N = 5877), a nationally representative study of prevalence, risk factors, and social consequences of psychiatric disorders in the US. Discrete time survival analysis and population attributable risk methodologies were utilized. RESULTS: Among those sexually abused as children, odds of suicide attempts were 2-4 times higher among women and 4-11 times higher among men, compared with those not abused, controlling for other adversities. Odds ratios were reduced but most remained statistically significant after adjusting for lifetime psychiatric illnesses preceding suicide attempts. In the same predictive equation, 79% of serious suicide attempts among women could be attributed to psychiatric disorders while 12% was attributable to rape and 7% to molestation. The highest probability of a first attempt was during early adolescence for those who were sexually abused and had a lifetime disorder, but it was 8-12 years older for those sexually abused without any disorders. CONCLUSIONS: In the US, a strong association exists between child sexual abuse and suicidal behaviour, mediated by psychopathology. There is a substantial proportion of suicide risk attributable to child sexual abuse beyond the presence of psychopathology and other adversities. From a clinical standpoint, abuse survivors represent a high-risk population for suicidal behaviour. Further research into this preventable antecedent of suicide attempts is necessary.     

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.     

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.     

Psychiatric and social aspects of suicidal behaviour in prisons

BACKGROUND: Suicidal behaviour and completed suicide are serious problems within British prisons, leading to significant morbidity and mortality, and are the focus of major efforts towards their prevention. AIM: To explore the demographic, social and psychiatric correlates of suicidal behaviour in prisons in England and Wales and their relationship with health service use; and to develop a combined psychosocial model of risk. METHOD: This report analyses the prevalence of suicidal ideation and suicide attempts in the ONS National Prison Survey, and their association with the presence of psychiatric disorders, personality disorder, substance abuse and social risk factors. These data were compared with data from the second national survey of psychiatric morbidity in adults living at home. In both surveys, a two-phase interviewing procedure was used, covering general health, health service use, assessment of psychiatric disorders, life events, social supports, suicidal behaviour, activities of daily living, sociodemographic data, substance abuse and intelligence. RESULTS: Suicidal thoughts and suicide attempts were commoner in prisons than in the general population and these were significantly associated with higher rates of psychosis, neurosis and personality disorder in prisons. In addition, demographic and factors such as being young, single, white, leaving school early and experiencing poor social support and significant social adversity were important risk factors for suicidal thoughts. Crucially, there was no separate category of people at suicidal risk who did not have psychiatric disorders. CONCLUSIONS: The high rates of suicidal behaviour in prisons cannot be addressed without adequate attention to the high rates of psychiatric disorder and vulnerability factors in prisoners.     

Managing post-sexual assault suicide risk

Suicidal ideation and suicidal behavior are common after experiencing a sexual assault. Therefore, it is imperative to assess for and manage suicidal ideation using evidence-based techniques after a sexual assault medical forensic examination (SAMFE). We assessed factors associated with higher suicidal ideation identified in a post-SAMFE mental health screening conducted over the phone and strategies to manage suicide risk. We also discuss three case examples and unique considerations when assessing post-SAMFE suicide risk. It was found that among individuals who completed a post-SAMFE screen, individuals who have been previously hospitalized for a mental health problem, who had higher acute stress symptoms, and who were homeless reported more suicidal ideation than those without those histories or symptom presentations. No matter the risk factors for suicidal ideation post-SAMFE, it is essential to screen all individuals post-SAMFE due to their high risk for suicidal ideation and death by suicide.

     

Personality and reports of suicide ideation among depressed adults 50 years of age or older

BACKGROUND: Accuracy in patient reports of suicide ideation is a concern in clinical assessment, given that some patients deny suicide ideation even when suicidal. Despite this concern, there is little research on the psychological processes driving reported suicide ideation in at-risk patients. METHODS: A cross-sectional design was used to examine the association of personality and suicide ideation in a clinical sample of 134 depressed adults 50 years and older. Patients completed a structured diagnostic interview, an interviewer-rated measure of current suicide ideation and self-report measures of personality (NEO-Personality Inventory Revised; NEO-PI-R) and hopelessness. The main outcome variable in logistic regression analyses was suicide ideator status; covariates included comorbid psychopathology, hopelessness and physical illness burden. Predictors were Neuroticism and Openness to Experience (OTE) scores on the NEO-PI-R. RESULTS: Elevated OTE and neuroticism were associated with suicide ideation in unadjusted analyses; OTE was also associated with suicide ideation in adjusted regression analyses. LIMITATIONS: This study used a cross-sectional methodology with depressed patients 50 years or older; it is possible that patients' depression severity may have influenced their responses to personality measures. Prospective studies of personality vulnerability to future suicide ideation are warranted. CONCLUSIONS: Elevated neuroticism increases the likelihood of reporting suicide ideation, just as it may enhance risk for suicidal behavior and death by suicide. The pattern for openness is markedly different. Although elevated openness increases the likelihood of reporting suicide ideation, previous research has shown that it may decrease risk of death by suicide, suggesting that the personality-mediated expression of suicide ideation may be adaptive in certain contexts. In contrast, low levels of openness may mute reports of suicide ideation in at-risk patients and confer risk for poor outcomes by potentially undermining clinician vigilance.     

Peer Functioning,Family Dysfunction,and Psychological Symptoms in a Risk Factor Model for Adolescent Inpatients' Suicidal Ideation Severity

Examined models of suicidal ideation severity that include two psychosocial risk factors (i.e., peer and family functioning) and four domains of psychological symptoms (i.e., generalized anxiety, depression, conduct problems, and substance abuse/dependence). Participants were 96 psychiatric inpatients (32 boys, 64 girls), ages 12 to 17, who were hospitalized because of concerns of suicidality. Adolescents completed a structured diagnostic interview, measures of suicidal ideation, and several dimensions of family and peer functioning. Results supported a model in which greater levels of perceived peer rejection and lower levels of close friendship support were associated directly with more severe suicidal ideation. In addition, indirect pathways included deviant peer affiliation and global family dysfunction related to suicidal ideation via substance use and depression symptoms. The results are among the first to demonstrate relations between suicidal ideation and several areas of adolescent peer functioning, as well as divergent processes for peer and family predictors of suicidal ideation.
