Anxiety disorders in suicidal youth.

OBJECTIVE: To test the hypothesis that anxiety disorders are associated with suicidal ideation and suicide attempts in a child and adolescent sample referred to a clinic. METHOD: The sample comprised 1979 patients aged 5 to 19 years who were assessed using the Schedule for Affective Disorders and Schizophrenia for School Aged Children--Present Episode (K-SADS-P) at an outpatient mood and anxiety disorders clinic. Subjects were stratified by age and categorized into mutually exclusive groups as being nonsuicidal (n = 817), having suicidal ideation (n = 768), or having attempted suicide (n = 394) in the current episode. Psychiatric diagnoses based on DSM-IV criteria were compared to determine if anxiety disorders were a risk factor for suicidal ideation and suicide attempts. Logistic regression was used to control for significant demographic characteristics and comorbid disorders. RESULTS: After stratifying by age, we found no differences across the 3 groups (ideators, attempters, and nonsuicidal youth) in rates of an anxiety disorder in general or in specific rates of panic disorder, agoraphobia, social phobia, simple phobia, and obsessive-compulsive disorder. Two salient findings involving anxiety disorders were noted with regression analysis. In younger children (age < or = 15 years), attempters had a significantly lower prevalence of separation anxiety disorder (SAD), compared with ideators (OR = 0.30; 95%CI, 0.11 to 0.80; P = 0.006) and nonsuicidal youngsters (OR = 0.14; 95%CI, 0.05 to 0.39; P < 0.0001). In older children (age > 15 years), generalized anxiety disorder (GAD) was more prevalent in ideators (OR = 1.65; 95%CI, 1.03 to 2.66; P = 0.03) than in nonsuicidal patients. CONCLUSIONS: Based on this clinical sample, the relation between pediatric anxiety disorder and suicidal ideation and suicide attempts is not straightforward. However, further studies in nonreferred samples are warranted.     

Control-related cognitions and depression among inpatient children and adolescents

In previous studies, children with numerous depressive symptoms have shown two patterns of control-related cognition: (1) low levels of perceived personal competence, and (2) "contingency uncertainty"--confusion regarding the causes of significant events. The generality of these findings was tested for more seriously disturbed children. Three child inpatient samples, from separate psychiatric hospitals, completed the Children's Depression Inventory (CDI) plus measures of control-related beliefs. In all three samples, the findings resembled those of previous studies: CDI scores were significantly related to low perceived competence and to contingency uncertainty; by contrast, CDI scores were only weakly related to perceived noncontingency. The findings suggest that depressive symptoms in children may be (1) more closely linked to "personal helplessness" than to "universal helplessness," and (2) more closely linked to uncertainty about the causes of events than to firm beliefs in noncontingency. The findings carry implications for etiology and treatment of child depression.     

Severity of depression and suicidal ideations among elderly people in Singapore

INTRODUCTION: Studies in the West have concluded that the severity of depression is the strongest predictor of the course of suicidal ideations among the elderly. However, Asian culture tends to be more reserved and this may impact on the reporting of suicidal ideations. This study aims to determine the prevalence of suicidal ideation among depressed elderly people in Singapore and attempts to investigate the relationship between severity of depression and suicidality.METHOD: Eighty consecutive depressed patients were recruited and severity of depressive symptoms rated with Beck's Depression Inventory (BDI). Suicidality was assessed using the Beck's Hopelessness Scale (BHS) and Beck's Suicide Intent Scale (BSS). Suicidal ideation was defined as any thought of wanting to kill oneself over the past seven days and not just a passive wish to die.RESULTS: 53.8% verbalized thoughts of wanting to kill themselves. Males were three times more likely to report suicidal thoughts. Severity of depression did not significantly influence the presence of suicidal thinking. The association of depression severity and suicidal ideations is not strongly supported.CONCLUSIONS: Elderly males were more likely to report suicidal ideations when depressed. Elderly patients who reported suicidal ideations were likely to be more severely depressed. However, in a depressed elderly person, the absence of suicidal ideations would not infer that the episode of depression was less severe.     

Method of assessment determines prevalence of suicidal ideation among patients with depression

BackgroundHow different ways of assessing suicidal ideation influence its prevalence, correlates and predictive validity among patients with major depressive disorder (MDD) remains unclear.MethodsWithin the Vantaa Primary Care Depression Study (PC-VDS, 91 patients) and the Vantaa Depression Study (VDS, 153 psychiatric out-and 41 inpatients), suicidal ideation was assessed with the Scale for Suicidal Ideation (SSI), Hamilton Depression Scale (HAM-D) item 3 and Beck Depression Inventory (BDI) item 9, and by asking whether patients had seriously considered suicide during the episode. The positive and negative predictive values (PPV, NPV) for suicide attempts during a six-month follow-up were investigated.ResultsDepending on the setting, 56–88% of patients had suicidal ideation in some of the assessments, but only 8–44% in all of them. Agreement ranged from negligible to moderate (kappa 0.06–0.64), being lowest among primary care patients. The correlates of suicidal ideation overlapped. No assessment had optimal sensitivity, specificity, PPV and NPV. Nevertheless, PPVs ranged up to 43%.ConclusionsWhich MDD patient is classified as having suicidal ideation depends strongly on the method of assessment, with the greatest variation likely in primary care. Differences in assessments may cause inconsistency in risk factors. Predicting suicide attempts is difficult, but not futile.     

Social inequalities in depression and suicidal ideation among older primary care patients

Purpose

Depression and suicide are major public health concerns, and are often unrecognized among the elderly. This study investigated social inequalities in depressive symptoms and suicidal ideation among older adults.

Methods

Data come from 1,226 participants in PROSPECT (Prevention of Suicide in Primary Care Elderly: Collaborative Trial), a large primary care-based intervention trial for late-life depression. Linear and logistic regressions were used to analyze depressive symptoms and suicidal ideation over the 2-year follow-up period.

Results

Mean Hamilton Depression Rating Scale (HDRS) scores were significantly higher among participants in financial strain [regression coefficient (b) = 1.78, 95 % confidence interval (CI) = 0.67–2.89] and with annual incomes below $20,000 (b = 1.67, CI = 0.34–3.00). Financial strain was also associated with a higher risk of suicidal ideation (odds ratio = 2.35, CI = 1.38–3.98).

Conclusions

There exist marked social inequalities in depressive symptoms and suicidal ideation among older adults attending primary care practices, the setting in which depression is most commonly treated. Our results justify continued efforts to understand the mechanisms generating such inequalities and to recognize and provide effective treatments for depression among high-risk populations.     

Factor structure and psychometric properties of the Modified Scale for Suicidal Ideation among suicidal youth

Background: Although suicidal behaviors occur at a high rate in adolescence, relatively few interview‐based measures are available to assess suicidal ideation among youth. Existing interview measures are limited by a paucity of empirical study, a failure to conform to standard suicide nomenclature, or a lengthy administration time. This study presents data on the psychometric properties and factor structure of the brief, layperson‐administered Modified Scale for Suicidal Ideation (MSSI) among suicidal youth. Methods: The MSSI was administered to an inpatient sample of 102 suicidal youth aged 13–17 years. Additional interview and self‐report measures were administered to examine the convergent validity of the MSSI. Results: Consistent with previous findings among suicidal adults, the MSSI displayed good internal consistency and expected patterns of convergent validity. Principal component analysis revealed a bidimensional structure, with factors corresponding to (1) Desire and Ideation and (2) Plans and Preparations. Each factor displayed acceptable internal consistency and expected patterns of convergent validity via associations with hopelessness, depressive symptoms, impulsivity, and a self‐report measure of suicidal behaviors. The Plans and Preparations factor significantly associated with the presence of a current suicide attempt and with greater suicide intent among attempters, whereas the Desire and Ideation factor did not. Conclusions: The MSSI appears to be a reliable and valid instrument to assess suicidal ideation among distressed youth. Clinicians are encouraged to pay particular attention to responses on the Plans and Preparations factor given its stronger association with suicide attempt and more serious suicide intent.

An outpatient treatment alternative for suicidal youth

The present study demonstrates the safety and effectiveness of an outpatient treatment program for suicidal children and adolescents. Pre- and post-treatment measures of patient behavior and family functioning are presented for 47 adolescents and latency-aged children who received treatment from the Systemic Crisis Intervention Program at the Houston Child Guidance Center. Follow-up was conducted at three and six months and at a point between 12-18 months. All measures indicated significant long-term improvement. Data concerning post-institutional use and suicidal behavior are also presented.     

Bipolar depression and suicidal behavior

Suicide is a frequent and tragic consequence of bipolar depression. The prevention of suicidal behavior (SB) need an assessment of vulnerability traits related related to SB (personal suicide history, impulsive traits...), characteristics of depression (mixed depression, subtype of bipolar disorder...), psychiatric comorbidities and stressors psycho-social. Meanwhile, the characteristics of suicidal behavior (ie: severe or multiple attempts) suggest a diagnosis of bipolar disorder rather than major depressive disorder. In addition to a correct screening of bipolar disorders and assessment of suicidal behavior, the removal of lethal means, networking and treatment of depression reduces the risk of suicidal behavior. Finally, lithium may have a particular interest in subjects at high risk of suicide.     

Hypothalamic-pituitary-adrenal axis function and suicidal behavior in depression.

Hypothalamic-pituitary-adrenal (HPA) axis function was examined in relation to suicidal behavior in depression. There were no significant differences between depressed patients who had or had not attempted suicide for either cerebrospinal fluid concentrations of corticotropin-releasing hormone, plasma cortisol levels predexamethasone or postdexamethasone, or for urinary-free cortisol outputs. However, depressed patients who had made a violent suicide attempt had significantly higher 4 PM and maximum postdexamethasone plasma cortisol levels, and significantly more of them were cortisol nonsuppressors than patients who had made nonviolent suicide attempts. A 5-year follow-up was carried out. There were no significant differences on indices of HPA function between depressed patients who did or did not reattempt suicide during the follow-up or who had never attempted suicide. These results suggest the possibility that dysregulation of the HPA axis may be a determinant of violent suicidal behavior in depression.     

Hypothalamus-pituitary-adrenal system regulation and suicidal behavior in depression.

BACKGROUND: One of the most demanding tasks in psychiatry is to protect patients from suicidal attempts. Preventive strategies could be improved by increasing our knowledge on the pathophysiologic disturbances underlying this behavior. More than 70-80% of suicides occur in the context of depressive disorders, in which dysregulation of the hypothalamus-pituitary-adrenal (HPA) axis is one of the most prominent neurobiological findings. So far data on the involvement of the HPA axis in the pathophysiology of suicidal behavior in depressed patients are controversial. METHODS: In this retrospective study, we administered the combined dexamethasone-suppression/CRH stimulation (Dex/CRH) test to 310 patients with a depressive syndrome characterized at admission for acute and past suicidal behavior within the first 10 days after hospitalization. RESULTS: Suicidal behavior in depressed patients, including past and recent suicide attempts as well as suicidal ideation, was associated with a lower adrenocorticotropin and cortisol response in the combined Dex/CRH test, with lowest hormone levels observed in patients with a recent suicide attempt. DISCUSSION: The findings suggest that suicidal behavior may alter HPA axis regulation in depressed patients. Large-scale prospective studies assessing neuroendocrine changes may help to develop predictors for an early identification of patients at risk for committing suicide.

Psychosocial and risk behavior correlates of youth suicide attempts and suicidal ideation.

OBJECTIVE: To identify the independent psychosocial and risk behavior correlates of suicidal ideation and attempts. METHOD: The relationships between suicidal ideation or attempts and family environment, subject characteristics, and various risk behaviors were examined among 1,285 randomly selected children and adolescents, aged 9 through 17 years, of whom 42 (3.3%) had attempted suicide and 67 (5.2%) had expressed suicidal ideation only. The youths and their parents were enumerated and interviewed between December 1991 and July 1992 as part of the NIMH Methods for the Epidemiology of Child and Adolescent Mental Disorders (MECA) Study. RESULTS: Compared with subjects with suicidal ideation only, attempters were significantly more likely to have experienced stressful life events, to have become sexually active, to have smoked more than one cigarette daily, and to have a history of ever having smoked marijuana. After adjusting for sociodemographic characteristics, a statistically significant association was found between suicidal ideation or attempt and stressful life events, poor family environment, parental psychiatric history, low parental monitoring, low instrumental and social competence, sexual activity, marijuana use, recent drunkenness, current smoking, and physical fighting. Even after further adjusting for the presence of a mood, anxiety, or disruptive disorder, a significant association persisted between suicidal ideation or attempts and poor family environment, low parental monitoring, low youth instrumental competence, sexual activity, recent drunkenness, current smoking, and physical fighting. CONCLUSION: Low parental monitoring and risk behaviors (such as smoking, physical fighting, alcohol intoxication, and sexual activity) are independently associated with increased risk of suicidal ideation and attempts, even after adjusting for the presence of psychiatric disorder and sociodemographic variables.
