OBJECTIVE: The aim of this study was to evaluate the prevalence of self-mutilation (SM) in male substance-dependent inpatients, and to investigate the relationship of SM with childhood abuse and neglect, axis I disorders and personality disorders. METHODS: Participants were 112 consecutively admitted male substance dependents (56 alcohol and 56 drug). Substance dependence was diagnosed by means of the Structured Clinical Interview for DSM-IV (SCID-I, Turkish version). Patients were evaluated by the Childhood Abuse and Neglect Questionnaire, SCID-I, SCID-II, Beck Depression Inventory and Beck Anxiety Inventory. RESULTS: Among substance-dependent patients, SM was found to be present in 33% (SM group). Mean age and educational status were lower in the SM group. Moreover rates of being single, history of childhood physical and emotional abuse and neglect, suicide attempt history and personality disorder were higher. Mean depression and anxiety scores were also higher in the SM group. Personality disorder, physical abuse, suicide attempt history and drug dependency were predictors for SM. CONCLUSIONS: SM is more common in drug dependents than alcohol dependents. Also results of this study suggest that among Turkish substance dependents SM might be related to the presence of personality disorder and childhood physical abuse and suicide attempts. 相似文献

Family history of suicidal behavior and personal history of childhood abuse are reported risk factors for suicide attempts and suicide completion. We aim to quantify the additive effect of family history of suicidal behavior and different subtypes of childhood abuse on suicidal behavior. We examined a sample of 496 suicide attempters, comparing individuals with family history of suicidal behavior and personal history of childhood (physical or sexual) abuse, individuals with family history of suicidal behavior only, individuals with history of early traumatic experiences only, and individuals with none of these two risk factors with regards to suicidal features. An additive effect was found for the age at the first attempt in suicide attempters with both family history of suicidal behavior and either physical or sexual abuse. No significant interactions were found between family history of suicidal behavior and childhood trauma in relation to any characteristics of suicidal behavior. Subjects presenting family history of suicidal behavior and childhood abuse attempt suicide earlier in life than subjects with just one or none of them, particularly if they were sexually abused. Other suicidality indexes were only partially or not associated with this combination of risk factors. A careful assessment of patients with both family history of suicidal behavior and childhood abuse could help to prevent future suicide attempts, particularly in young people. 相似文献

Childhood abuse and neglect: specificity of effects on adolescent and young adult depression and suicidality 总被引:10,自引:0,他引:10

OBJECTIVE: To investigate the magnitude and independence of the effects of childhood neglect, physical abuse, and sexual abuse on adolescent and adult depression and suicidal behavior. METHOD: A cohort of 776 randomly selected children was studied from a mean age of 5 years to adulthood in 1975, 1983, 1986, and 1992 during a 17-year period. Assessments included a range of child, family, and environmental risks and psychiatric disorders. A history of abuse was determined by official abuse records and by retrospective self-report in early adulthood on 639 youths. Attrition rate since 1983 has been less than 5%. RESULTS: Adolescents and young adults with a history of childhood maltreatment were 3 times more likely to become depressed or suicidal compared with individuals without such a history (p < .01). Adverse contextual factors, including family environment, parent and child characteristics, accounted for much of the increased risk for depressive disorders and suicide attempts in adolescence but not in adulthood (p < .01). The effects of childhood sexual abuse were largest and most independent of associated factors. Risk of repeated suicide attempts was 8 times greater for youths with a sexual abuse history (odds ratio = 8.40, p < .01). CONCLUSIONS: Individuals with a history of sexual abuse are at greater risk of becoming depressed or suicidal during adolescence and young adulthood. Adolescence is the most vulnerable period for those youths who may attempt suicide repeatedly. Many of the apparent effects of neglect, in contrast, may be attributable to a range of contextual factors, suggesting broader focus for intervention in these cases. 相似文献

The relationship of childhood abuse to impulsivity and suicidal behavior in adults with major depression. 总被引:8,自引:0,他引:8

OBJECTIVE: This study investigated whether a higher frequency of reported childhood trauma would be found in depressed adults with higher levels of trait impulsivity, aggression, and suicidal behavior. METHOD: In 136 depressed adult inpatients, the authors assessed trait impulsivity, aggression history, and number of lifetime suicide attempts as well as the medical lethality and the intent to die associated with the most lethal attempt. These variables were then compared between those with and those without a reported history of childhood physical or sexual abuse. RESULTS: Subjects who reported an abuse history were more likely to have made a suicide attempt and had significantly higher impulsivity and aggression scores than those who did not report an abuse history. Impulsivity and aggression scores were significantly higher in subjects with a history of at least one suicide attempt. A logistic regression analysis revealed that abuse history remained significantly associated with suicide attempt status after adjustment for impulsivity, aggression history, and presence of borderline personality disorder. Among those who attempted suicide, there were no significant differences in severity of suicidal behavior between those with and without a childhood history of abuse. CONCLUSIONS: Abuse in childhood may constitute an environmental risk factor for the development of trait impulsivity and aggression as well as suicide attempts in depressed adults. Alternatively, impulsivity and aggression may be inherited traits underlying both childhood abuse and suicidal behavior in adulthood disorders. Additional research is needed to estimate the relative contributions of heredity and environmental experience to the development of impulsivity, aggression, and suicidal behavior. 相似文献

Although general population studies have reported that childhood trauma predisposes individuals to suicidal behavior, there have been few clinical studies in depressed patients. A series of 108 patients with unipolar depression were evaluated for their suicide attempt history and completed the 34-item Childhood Trauma Questionnaire (CTQ). Patients were also interviewed with the Brown-Goodwin Lifetime History of Aggression (BGLHA) scale. Out of 108 patients with depression, 47 (43.5%) had attempted suicide. Significantly more of the depressed patients who had attempted suicide were female, single, and unemployed. Patients who had attempted suicide had significantly higher total CTQ scores and higher CTQ scores for emotional abuse and emotional neglect, as well as higher BGLHA scores. Logistic regression identified being female, being unemployed, having undergone childhood emotional neglect, and high BGLHA scores as significantly associated with making a suicide attempt. Suicidal behavior in unipolar depression appears to be a multidetermined act, with sociodemographic, developmental, and personality determinants. 相似文献

Suicidality, depression, and substance abuse in adolescence 总被引:6,自引:0,他引:6
The authors assessed the occurrence of suicidal ideation, suicide attempts, major depression, and substance abuse in a sample of 424 apparently healthy college students 16-19 years old. Major depression and substance abuse were independent and interactive risk factors for suicidal ideation and for suicide attempts; substance abuse had a particularly deleterious effect on men. A prolonged desire to be dead was a more specific risk factor for a suicide attempt than was a thought of suicide. The authors conclude that suicidal ideation in the presence of major depression and/or substance abuse in older adolescents should call forth greater concern for lethality. 相似文献

Although considerable empirical work has been devoted to identifying risk factors for suicide attempts, most longitudinal research has studied recurrent attempts rather than first lifetime attempts. The present study sought to examine prospective predictors of first lifetime suicide attempts among adults receiving treatment for substance use. Data were drawn from the National Treatment Improvement Evaluation Study, a study of addiction treatment programs. Data were collected at treatment intake, treatment exit, and one year post-treatment. Patients (n = 3518) with no lifetime history of suicide attempts at treatment intake were followed at treatment exit and one year post-treatment, when they reported on the occurrence of suicide attempts since the prior assessment. Prospective suicidal behavior was assessed using logistic regression in relation to sociodemographic variables, health-related work impairment, history of psychiatric treatment utilization, history of suicidal ideation, history of depressive symptoms, substance use, and childhood abuse, assessed at intake. Health-related work impairment, history of suicidal ideation, and childhood physical abuse significantly predicted first lifetime attempts in a multivariate analysis. Suicidal ideation, health-related functional impairments, and childhood physical abuse may be particularly important in assessing risk for first lifetime suicide attempts. Findings suggest that future clinical work and research would benefit from considering these factors when identifying individuals at heightened risk of making a first suicide attempt. 相似文献

Posttraumatic stress disorder and major depressive disorder are well-established risk factors for suicidal behavior. This study compared depressed suicide attempters with and without comorbid posttraumatic stress disorder with respect to additional diagnoses, global functioning, depressive symptoms, substance abuse, history of traumatic exposure, and suicidal behavior. Adult patients consecutively admitted to a general hospital after a suicide attempt were interviewed and assessed for DSM-IV diagnosis and clinical correlates. Sixty-four patients (71%) were diagnosed with depression; of them, 21 patients (32%) had posttraumatic stress disorder. There were no group differences in social adjustment, depressive symptoms, or suicidal intent. However, the group with comorbid depression and posttraumatic stress disorder had more additional Axis I diagnoses, a higher degree of childhood trauma exposure, and more often reported previous suicide attempts, non-suicidal self-harm, and vengeful suicidal motives. These findings underline the clinical importance of diagnosis and treatment of posttraumatic stress disorder in suicide attempters. 相似文献

A number of factors including hopelessness have been identified as amplifying suicide risk. Alexithymia has recently been investigated as a predictor of suicidal behavior. The prevalence of the personality trait alexithymia in suicide attempters as well as other predictors of suicidal behavior were investigated in this study. One hundred suicide attempters were compared to 60 healthy controls on the measures of hopelessness, alexithymia, depression and suicidal ideation. First-timers and repetitive suicide attempters, males and females, married and unmarried suicide attempters were compared to each other in the suicide attempter group. The correlations of hopelessness, depression and alexithymia with suicidal intent and suicide lethality were investigated. The suicide attempter group did not display significantly higher scores on the alexithymia measure, compared to healthy controls. Alexithymia neither seemed to be a prevalent personality trait in suicide attempters nor a sensitive predictor of suicidality. The subscales of Toronto Alexithymia Scale measuring difficulty in identification and expression of feelings also did not reveal a significant difference between the two groups. Suicide attempters were more depressive, more hopeless and displayed greater suicidal ideation than healthy controls. Severity of depression was a stronger predictor of suicidal intent than hopelessness in the suicide attempter group. The lethality of the suicide attempt did not correlate with any of the psychometric measures. These findings propose that difficulty in the identification and articulation of feelings does not comprise a risk factor for suicidal behavior. 相似文献

The prevalence of antisocial personality disorder (ASPD) in treatment-seeking Turkish substance dependent patients and the relationship of ASPD with clinical characteristics were studied. Participants were 132 inpatients with substance dependence according to the Structured Clinical Interview for DSM-IV (SCID-I), Turkish version. The clinician applied a semi-structured socio-demographic form, SCID-I, SCID-II, Childhood Abuse and Neglect Questionnaire (CANQ), Michigan Alcoholism Screening Test (MAST), Beck Depression Inventory (BDI), and Beck Anxiety Inventory (BAI). Among the 132 substance dependent patients, 31 (23.5%) had ASPD diagnosis and 56 (42.4%) had no personality disorder or personality traits. Rate of childhood physical abuse, childhood verbal abuse, childhood neglect, suicide attempt history, self-destructive behavior and lifetime major depression were higher among patients with ASPD. Also mean scores of BDI, BAI and MAST were higher among patients with ASPD. The high rate of ASPD found among Turkish substance dependent patients suggests that special attention must be paid to identify ASPD in this group. Findings in this study showed that there is an association between ASPD and childhood abuse, lifetime major depression and severity of substance use. 相似文献

Hostility and childhood sexual abuse as predictors of suicidal behaviour in Borderline Personality Disorder 总被引:1,自引:0,他引:1

Impulsivity is a multidimensional construct and has been previously associated with suicidal behaviour in borderline personality disorder (BPD). This study examined the associations between suicidal behaviour and impulsivity-related personality traits, as well as history of childhood sexual abuse, in 76 patients diagnosed with BPD using both the Structured Interview for Diagnostic and Statistical Manual of Mental Disorders III (DSM-III) Axis-II diagnoses and the self-personality questionnaire. Impulsivity-related traits were measured using the Barratt Impulsiveness Scale-11 (BIS-11), the Buss–Durkee Hostility Inventory (BDHI) and the Temperament and Character Inventory-Revised (TCI-R). We found that hostility and childhood sexual abuse, but not impulsivity or other temperament traits, significantly predicted the presence, number and severity of previous suicide attempts. Hostility traits and childhood sexual abuse showed an impact on suicide attempts in BPD. Our results support previous findings indicating that high levels of hostility and having suffered sexual abuse during childhood lead to an increased risk for suicidal behaviour in BPD. 相似文献

Risk factors for suicidal behaviour include adverse life events as well as biochemical parameters acting, e.g. within the
hypothalamic–pituitary–adrenal axis and/or monoaminergic systems. The aim of the present investigation was to study stressful
life events and biological stress markers among former psychiatric inpatients, who were followed up 12 years after an index
suicide attempt. At the time of the index suicide attempt, and before treatment, cerebrospinal fluid (CSF) samples were taken,
and 24 h (h) urine (U) was collected. 3-Methoxy-4-hydroxyphenylglycole (MHPG) in CSF and 24 h urinary samples of cortisol
and noradrenaline/adrenaline (NA/A) were analysed. Data concerning stressful life events were collected retrospectively from
all participants in the study through semi-structured interviews at follow-up. We found that patients who reported sexual
abuse during childhood and adolescence had significantly higher levels of CSF-MHPG and U-NA/A, than those who had not. Low
24 h U-cortisol was associated with feelings of neglect during childhood and adolescence. In conclusion, this study has shown
significant and discrepant biological stress-system findings in relation to some adverse life events. 相似文献

Axis II diagnoses of 50 applicants for long-term inpatient treatment were obtained using the Personality Diagnostic Questionnaire,
Revised. Clinical records were coded for evidence of a history of childhood abuse or neglect. Seventy-five percent of patients
with a diagnosis of Borderline Personality Disorder (BPD) had histories of some type of abuse, compared with 33 percent of
the nonborderline patients. A principal components analysis of the eight DSM-III-R criteria for BPD and histories of abuse
and neglect showed that abuse history is correlated with the criteria of unstable relationships, feelings of emptiness, and
abandonment fears, whereas neglect history is correlated with suicidal behavior. Affective instability, intense anger, and
identity disturbance were uncorrelated with abuse or neglect. Thus, the affective symptoms of BPD appear to be unrelated to
aversive childhood events, consistent with the concept of a subtype of BPD dominated by affective dysregulation. 相似文献

Summary The life-time prevalence of suicide attempts in a Swiss population, interviewed four times between the ages of 20 and 30 years, was 3.8% (females 5.4%, males 2.1%). One fifth of the 30-year-olds reported persistent suicidal ideation. In comparison with controls, attempters reported a more disturbed childhood, and subjects with multiple attempts reported more sexual abuse. Over 10 years attempters persistently showed more negative affectivity, more feelings of helplessness and lower selfesteem. At age 30 they were higher on the scales neuroticism, masculinity and aggressivity in a personality test. Over ten years, a higher than expected comorbidity appeared of suicide attempts with depressive and anxiety disorders, with substance abuse, and with sociopathic features. 相似文献

Bipolar disorder with comorbid cluster B personality disorder features: impact on suicidality 总被引:2,自引:0,他引:2
BACKGROUND: Because of their overlapping phenomenology and mutually chronic, persistent nature, distinctions between bipolar disorder and cluster B personality disorders remain a source of unresolved clinical controversy. The extent to which comorbid personality disorders impact course and outcome for bipolar patients also has received little systematic study. METHOD: One hundred DSM-IV bipolar I (N = 73) or II (N = 27) patients consecutively underwent diagnostic evaluations with structured clinical interviews for DSM-IV Axis I and cluster B Axis II disorders, along with assessments of histories of childhood trauma or abuse. Cluster B diagnostic comorbidity was examined relative to lifetime substance abuse, suicide attempt histories, and other clinical features. RESULTS: Thirty percent of subjects met DSM-IV criteria for a cluster B personality disorder (17% borderline, 6% antisocial, 5% histrionic, 8% narcissistic). Cluster B diagnoses were significantly linked with histories of childhood emotional abuse (p = .009), physical abuse (p = .014), and emotional neglect (p = .022), but not sexual abuse or physical neglect. Cluster B comorbidity was associated with significantly more lifetime suicide attempts and current depression. Lifetime suicide attempts were significantly associated with cluster B comorbidity (OR = 3.195, 95% CI = 1.124 to 9.088), controlling for current depression severity, lifetime substance abuse, and past sexual or emotional abuse. CONCLUSIONS: Cluster B personality disorders are prevalent comorbid conditions identifiable in a substantial number of individuals with bipolar disorder, making an independent contribution to increased lifetime suicide risk. 相似文献

Introduction Familial clustering of suicidal behaviour and psychopathology has been reported in young suicide attempters. Most of these
studies were predominantly carried out in clinical treatment settings and lacked statistical power to assess the independent
and modifying influences of own and familial psychopathology and suicidal behaviour.
Methods We carried out a population-based record-linkage study with a nested case control design. The 14,440 individuals hospitalised
due to suicide attempt (cases) and 144,400 matched controls were born in Sweden between 1968 and 1980 and followed up till
December 31, 1999.
Results Among the strongest independent familial risk factors for youth suicide attempt were siblings’ (OR 3.4; 2.8–4.1), maternal
(OR 2.7; 2.5–3.1) and paternal (OR 1.9; 1.7–2.1) suicide attempt. Other important risk factors were familial personality and
substance abuse disorders, maternal schizophrenia, non-affective psychoses and organic disorders and parental neurotic, stress-related
and somatoform disorders (1.9–3.2 fold increase), and paternal (OR 1.9; 1.6–2.3) and maternal (OR 1.8; 1.3–2.4) suicide completion.
Mental illnesses in index subjects, particularly substance abuse, affective and personality disorders, were the dominant determinants
of suicide attempt. Strong interactions were observed between psychopathology in index subjects and familial suicidality.
Familial suicide completion had a stronger effect on suicide attempt of earlier onset and on boys. Nearly half (47%) of all
suicide attempts could be attributed to familial psychopathology (13%), family suicide attempt (7%) and suicide completion
(1%) and own psychopathology (25%).
Conclusion Early recognition and adequate treatment of individual mental illness contribute to prevent youth suicide attempts. Children
of parents with psychopathology and suicidal behaviour should receive early support and attention. Evaluation of familial
suicidal behaviour seems to be vital for suicide risk assessment in young psychiatric inpatients. There appears to be an independent
effect of familial suicidal behaviour as well as familial psychopathology on youth suicide attempt beyond the transmission
of mental illness. 相似文献

Introduction
Schizophrenia is associated with a significant risk of suicide, and suicide still remains one of the main causes of death in schizophrenic patients. Beside classic risk factors for suicidality, temperament and character traits have been researched and considered as risk factors for suicidal behavior in recent years.Method
Subjects were 94 patients with schizophrenia who were under treatment. All patients were in a stable phase of the illness. Patients with lifetime suicide attempt (n = 46) and without suicidal attempt (n = 48) were compared with each other in terms of temperament and character traits by using the Temperament and Character Inventory.Results
Harm avoidance and persistence scores were higher in suicidal schizophrenic patients compared with nonsuicidal schizophrenic patients. The scores of self-directedness and cooperativeness were lower in suicidal schizophrenic patients compared with nonsuicidal schizophrenic patients. These 4 variables remained significant predictors of lifetime suicidal attempts in a logistic regression model.Conclusion
To the best of our knowledge, the present study is the first that specifically compares schizophrenic patients with and without suicidal behavior by the Cloninger temperament and character model. Our data indicate that schizophrenic patients will show a greater risk for suicide according to certain personality configurations. However, to establish causal relationships between personality and suicidality in schizophrenia, longitudinal studies are warranted within a multifactorial interactive framework of biologic and clinical variables. 相似文献19.

OBJECTIVE: First-degree relatives of persons with mood disorder who attempt suicide are at greater risk for mood disorders and attempted or completed suicide. This study examined the shared and distinctive factors associated with familial mood disorders and familial suicidal behavior. METHOD: First-degree relatives' history of DSM-IV-defined mood disorder and suicidal behavior was recorded for 457 mood disorder probands, of whom 81% were inpatients and 62% were female. Probands' lifetime severity of aggression and impulsivity were rated, and probands' reports of childhood physical or sexual abuse, suicide attempts, and age at onset of mood disorder were recorded. Univariate and multivariate analyses were carried out to identify predictors of suicidal acts in first-degree relatives. RESULTS: A total of 23.2% of the probands with mood disorder who had attempted suicide had a first-degree relative with a history of suicidal behavior, compared with 13.2% of the probands with mood disorder who had not attempted suicide (odds ratio=1.99, 95% CI=1.21-3.26). Thirty percent (30.8%) of the first-degree relatives with a diagnosis of mood disorder also manifested suicidal behavior, compared with 6.6% of the first-degree relatives with no mood disorder diagnosis (odds ratio=6.25, 95% CI=3.44-11.35). Probands with and without a history of suicide attempts did not differ in the incidence of mood disorder in first-degree relatives (50.6% versus 48.1%). Rates of reported childhood abuse and severity of lifetime aggression were higher in probands with a family history of suicidal behavior. Earlier age at onset of mood disorder in probands was associated with greater lifetime severity of aggression and higher rates of reported childhood abuse, mood disorder in first-degree relatives, and suicidal behavior in first-degree relatives. CONCLUSIONS: Risk for suicidal behavior in families of probands with mood disorders appears related to early onset of mood disorders, aggressive/impulsive traits, and reported childhood abuse in probands. Studies of such clinical features in at-risk relatives are under way to determine the relative transmission of these clinical features. 相似文献

BACKGROUND: Recurrent brief depressive disorder (RBD) and major depressive disorder (MDD) share the same diagnostic picture of full-blown depression and are both associated with increased suicide attempt rates. However, longitudinal diagnostic shifts from RBD to MDD or vice versa, called "combined depression" (CD), have demonstrated a substantially higher risk of suicide attempts in epidemiologic and clinical studies. Following the stress-diathesis model of suicidal behavior, we compared possible triggers and thresholds for suicidal behavior among patients with RBD, MDD, and CD. RBD and MDD diagnoses were based on DSM-IV criteria. Furthermore, the goal of this study was to determine if impulsivity as an underlying factor could explain high suicide attempt rates in CD. METHOD: A structured clinical interview evaluating comorbid Axis I and II disorders and RBD and a battery of instruments assessing suicidal behavior were administered to 101 patients with RBD (N = 27), MDD (N = 33), or CD (N = 41). RESULTS: Patients with CD showed significantly higher (p < .05) scores on measures of suicidal behavior in comparison with RBD and MDD patients. Together with comorbid substance abuse and marital status, CD was among the highest-ranking risk factors for suicide attempts. Impulsivity was identified as a major underlying factor, predicting 80.7% of suicide attempts. CONCLUSION: CD seems to be an important clinical risk factor for the prediction of suicide attempts, similar to risk factors such as substance use disorders and borderline personality disorder. All of these factors share the same diathesis for increased impulsivity and suicidal ideation, which could explain comorbidity and suicidal behavior. The coexistence of a greater propensity for suicidal ideation and impulsivity in RBD might also explain why such patients are more prone to attempt suicide, even if they do not, in the case of RBD, meet the duration criteria for MDD. 相似文献
