Panic attacks and suicide attempts in mid-adolescence

Does Conduct, Oppositional Defiant, and Panic Disorder Symptoms Associate with Suicidal Ideations Among African American Adolescents?

Previous studies suggest that mental illness symptoms among adolescents, such as conduct disorder, oppositional defiant disorder, and panic disorder symptoms often associate with suicidal ideations. Despite this, few studies have examined whether these mental illness symptoms associate with suicidal ideations among African American adolescents. To address these limitations, the current study examined whether conduct disorder, oppositional defiant disorder, and panic disorder symptoms associated with suicidal ideations (N = 261). Using binominal logistic regression, results suggest that conduct disorder symptoms were associated with a higher likelihood of endorsing suicidal ideations than oppositional defiant disorder symptoms. Finally, panic disorder symptoms and gender differences were not associated with suicidal ideations. Preventive efforts and psychotherapy implications are discussed.

Somatic Symptoms of Anxiety and Suicide Ideation Among Treatment-Seeking Youth With Anxiety Disorders

OBJECTIVE

The severity of anxiety, in general, has been associated with suicide ideation (SI) among youth, but research has yet to examine the specific anxiety symptoms that may contribute to SI among youth. This study examined the severity of specific anxiety symptom clusters (i.e., tense/restless, somatic/autonomic symptoms, humiliation/rejection, performing in public, separation anxiety, perfectionism, and anxious coping) and SI in youth who met diagnostic criteria for an anxiety disorder.

METHOD

Participants (N = 87) were treatment-seeking children and adolescents ages 6-17 (M = 11.1 years, SD = 3.06; 52.9% male) diagnosed with a principal anxiety disorder. Youth and their parents completed measures of youth anxiety symptom severity, depression, and SI.

RESULTS

Hierarchical linear regressions revealed that when anxiety symptom clusters were entered simultaneously, only youth self-reported (and not parent-reported) somatic/autonomic symptoms of anxiety significantly predicted SI, after controlling for depression and sex. Importantly, the relationship between somatic/autonomic symptoms of anxiety and SI was stronger than that between depression and SI.

CONCLUSIONS

These results suggest that assessing somatic symptoms of anxiety is especially important when quantifying suicide risk among anxiety-disordered youth.

[Predictors of suicidal behaviour in adolescents with depressive disorders]

A review of recent publications is devoted to risk factors for suicidal behavior in adolescents with depressive disorders. The authors summarized Russian and international studies on the clinical course of affective disorders, in particular bipolar disorders, their clinical heterogeneity and incompleteness in adolescence. Particular attention is given to the complexity of early identification of predictors of suicidal behavior in depressive disorders due to comprehensiveness of exogenous and endogenous effects characteristic of adolescence. The role of genetic loading for affective disorders, problems of children having parents with affective disorders, social and psychological factors (violence in families, school bullying etc.) and risks of suicidal behavior are described. It is of great significance to investigate premorbid adjustment, subaffective manifestations of disorders in adolescence to predict the trajectory of the disease, its complications in the form of suicidal behavior and opportunities for early intervention.

The relationship between impulsivity and panic disorder-agoraphobia: The role of affective temperament

There are opinions regarding that impulsivity may play a role in the pathogenesis of neuropsychiatric disorders. The aim of this study was to investigate the relationship between impulsivity and panic disorder (PD) in the patient group, to compare impulsivity and affective temperamental traits between patients and healthy controls and to investigate whether there is a relationship between impulsivity and affective temperamental traits. Participants comprised 70 patients with PD and 58 healthy volunteers. The Panic Agoraphobia Scale (PAS), the Barratt Impulsiveness Scale (BIS-11) and the Temperament Evaluation of Memphis, Pisa, Paris, San Diego Autoquestionnaire (TEMPS-A) were applied. Patients have significantly higher scores in affective temperament (except hyperthymic) and attentional impulsiveness subscales than the healthy controls. Positive and negative correlations were found between some PAS and BIS-11 scores as well as correlations between especially cyclothymic, hyperthymic, irritable and anxious subscale scores of the TEMPS-A and the BIS-11 scores in the patient group. The results of this study indicate a relationship between impulsivity and PD. The correlations found between affective temperament dimensions and impulsivity suggest how affective temperamental traits may influence different impulsivity dimensions.

Suicidality in Subjects With Anxiety or Obsessive-Compulsive and Related Disorders: Recent Advances

PURPOSE OF REVIEW

Historically, anxiety disorders have not been considered as important determinants of suicide, but in the last years, many works have challenged this assumption. Here, we will review the available evidence on the relationship between suicide and anxiety disorders (e.g., obsessive-compulsive disorder, post-traumatic stress disorder, generalized anxiety disorder, panic disorder, and body dysmorphic disorder), with special emphasis on findings published in the last years.

RECENT FINDINGS

Overall, anxiety disorders increase the risk of suicide. Specifically, 16% of patients with social anxiety disorder reported suicidal ideation in the previous month, and 18% of them had a history of suicide attempts. Similarly, in patients with panic disorder, suicidal ideation prevalence ranged between 17 and 32%, and 33% of them had a history of suicide attempts. Generalized anxiety disorder (GAD) was the most frequent anxiety disorder in completed suicides (present in 3% of people who committed suicide) and also subthreshold GAD was clearly linked to suicide ideation. Post-traumatic stress disorder was positively associated with suicidal ideation, and in patients with obsessive-compulsive disorder, suicide ideation rates ranged from 10 to 53% and suicide attempts from 1 to 46%. Body dysmorphic disorders presented a suicide ideation prevalence of about 80%. Suicide risk is increased in subjects with anxiety disorder. This risk is higher in the presence of comorbidities, but it is not clear whether it is independent from such comorbidities in some disorders.

Can Religious Beliefs be a Protective Factor for Suicidal Behavior? A Decision Tree Analysis in a Mid-Sized City in Iran, 2013

This study aimed to assess using tree-based models the impact of different dimensions of religion and other risk factors on suicide attempts in the Islamic Republic of Iran. Three hundred patients who attempted suicide and 300 age- and sex-matched patient attendants with other types of disease who referred to Kerman Afzalipour Hospital were recruited for this study following a convenience sampling. Religiosity was assessed by the Duke University Religion Index. A tree-based model was constructed using the Gini Index as the homogeneity criterion. A complementary discrimination analysis was also applied. Variables contributing to the construction of the tree were stressful life events, mental disorder, family support, and religious belief. Strong religious belief was a protective factor for those with a low number of stressful life events and those with a high mental disorder score; 72 % of those who formed these two groups had not attempted suicide. Moreover, 63 % of those with a high number of stressful life events, strong family support, strong problem-solving skills, and a low mental disorder score were less likely to attempt suicide. The significance of four other variables, GHQ, problem-coping skills, friend support, and neuroticism, was revealed in the discrimination analysis. Religious beliefs seem to be an independent factor that can predict risk for suicidal behavior. Based on the decision tree, religious beliefs among people with a high number of stressful life events might not be a dissuading factor. Such subjects need more family support and problem-solving skills.

Comorbid Anxiety and Depressive Symptoms in Children and Adolescents: A Systematic Review and Analysis

BACKGROUND

A large and extensive body of research has examined comorbid anxiety and depression in adults. Children and adolescents also frequently present with comorbid anxiety and depression; however, research and treatment require unique environmental and neurodevelopmental considerations in children. As a result, our understanding of comorbid anxiety and depression in children and adolescents is limited.

OBJECTIVE

The goal of this systematic review was to examine the current literature focused on comorbid anxiety and depression in children and adolescents. The review included theoretical conceptualizations as well as diagnostic, neurobiological, prevention, and treatment considerations. In addition, a proposed algorithm for the treatment of comorbid anxiety and depression in children/adolescents is provided.

METHODS

This systematic literature review included 3 discrete searches in Ovid SP Medline, PsycInfo, and PubMed.

RESULTS

The review included and synthesized 115 articles published between 1987 and 2015. The available evidence suggests that anxiety and depression are common in clinical populations of children and adolescents, and that comorbidity is likely underestimated in children and adolescents. Children and adolescents with comorbid anxiety and depression have unique presentations, greater symptom severity, and treatment resistance compared with those who have either disease in isolation. A dimensional approach may be necessary for the future development of diagnostic strategies and treatments for this population. Nascent neuroimaging work suggests that anxiety and depression each represents a distinct neurobiological phenotype.

CONCLUSIONS

The literature that is currently available suggests that comorbid anxiety and depression is a common presentation in children and adolescents. This diagnostic picture underscores the importance of comprehensive dimensional assessments and multimodal evidence-based approaches given the high disease severity. Future research on the neurobiology and the treatment of these common clinical conditions is warranted.

Suicidal behaviors in adolescents with ADHD: associations with depressive and other comorbidity, parent-child conflict, trauma exposure, and impairment

OBJECTIVE

To examine potential predictors of lifetime suicidal behaviors (SBs) in adolescents with ADHD.

METHOD

Participants were 101 adolescents with ADHD aged 11 to 18 years, evaluated for lifetime SB and psychopathology with semistructured interviews, and for lifetime trauma exposure, parent-child conflict, ADHD symptoms, and functional impairment with child, parent, and teacher ratings.

RESULTS

Controlling for the effects of age, female sex, and comorbid depressive and other disorders, lifetime SB (n = 28) remained significantly associated (p = .001) with parent-child conflict, and to a lesser extent (p < .05) with impairment in nonacademic domains of function and breadth of exposure to victimization events. Measures related to past and current ADHD symptoms and signs were not associated with lifetime SB.

CONCLUSION

Apart from depression, clinicians should pay particular attention to parent-child conflict, victimization trauma, and social impairment rather than levels of ADHD symptoms when weighing the likelihood of SB in youth with ADHD.

Panic Disorder and Agoraphobia in OCD patients: clinical profile and possible treatment implications

OBJECTIVE

Panic Disorder (PD) and agoraphobia (AG) are frequently comorbid with obsessive-compulsive disorder (OCD), but the correlates of these comorbidities in OCD are fairly unknown. The study aims were to: 1) estimate the prevalence of PD with or without AG (PD), AG without panic (AG) and PD and/or AG (PD/AG) in a large clinical sample of OCD patients and 2) compare the characteristics of individuals with and without these comorbid conditions.

METHOD

A cross-sectional study with 1001 patients of the Brazilian Research Consortium on Obsessive-Compulsive Spectrum Disorders using several assessment instruments, including the Dimensional Yale-Brown Obsessive-Compulsive Scale and the Structured Clinical Interview for DSM-IV-TR Axis I Disorders. Bivariate analyses were followed by logistic regression models.

RESULTS

The lifetime prevalence of PD was 15.3% (N=153), of AG 4.9% (N=49), and of PD/AG 20.2% (N=202). After logistic regression, hypochondriasis and specific phobia were common correlates of the three study groups. PD comorbidity was also associated with higher levels of anxiety, having children, major depression, bipolar I, generalized anxiety and posttraumatic stress disorders. Other independent correlates of AG were: dysthymia, bipolar II disorder, social phobia, impulsive-compulsive internet use, bulimia nervosa and binge eating disorder. Patients with PD/AG were also more likely to be married and to present high anxiety, separation anxiety disorder, major depression, impulsive-compulsive internet use, generalized anxiety, posttraumatic stress and binge eating disorders.

CONCLUSIONS

Some distinct correlates were obtained for PD and AG in OCD patients, indicating the need for more specific and tailored treatment strategies for individuals with each of these clinical profiles.

The associations between suicidal ideation and attempt and anxiety symptoms and the demographic, psychological, and social moderators in Taiwanese adolescents

The objectives of this study were to examine the associations between suicidal ideation and attempt and anxiety symptoms and the moderators in 5,027 Taiwanese adolescents. The associations between suicidal ideation and attempt and anxiety symptoms on the Taiwanese version of the Multidimensional Anxiety Scale for Children (MASC-T) were examined using logistic regression analysis. The moderating effects of demographic (gender and age), psychological (problematic alcohol use, severe depressive symptoms, and low self-esteem), and social factors (bullying victimization, and low family function) on the associations were examined. Adolescents who had anxiety symptoms were more likely to have suicidal ideation and attempt than those who did not have anxiety symptoms. Bullying victimization had a moderating effect on the association between suicidal ideation and anxiety symptoms. Assessment of suicidal ideation and attempt should be routine practice among adolescents who present with anxiety symptoms.

ADad 9: Suicidal behavior in Anxiety Disorders among adolescents in a rural community population in India

OBJECTIVE

The risk of suicidal behavior associated with Anxiety Disorders (AD) among adolescents is known. However, concurrent mood disorders complicate these findings, and no data is available from India as well as from the community. This study aimed to address the suicidal risk associated with AD from different perspectives.

METHODS

The authors prospectively collected data for 500 adolescents in a community with independent, trained raters. Risk for suicidal behavior was measured with SADPERSONS scale, socio-economic status with Modified Kuppuswamy Scale, depression and anxiety disorders with Beck Depression Inventory and Screen for Child Anxiety Related Emotional Disorders respectively. The relationship between predictors and need for preventive action was analyzed with univariate and multivariate regression analyses and a predictive model was built.

RESULTS

Suicidal behavior was increased by the presence of AD (adjusted OR = 6.28), the number of co-morbid AD (adjusted OR = 2.04), severity of the AD (adjusted OR = 4.98). Being a boy increased the risk of suicidal behavior associated with AD (adjusted OR = 9.37), Generalized Anxiety Disorder (adjusted OR = 5.65), Separation Anxiety Disorder (unadjusted OR = 3.28), Social Anxiety Disorder (unadjusted OR = 5.91) while controlling for the confounding effect of Depressive Disorder. Gender did not have an influence on Panic Disorder. Presence of AD and co-morbid Depressive Disorder significantly contributed to a risk model for suicidal behavior.

CONCLUSIONS

Anxiety Disorder is associated with the risk for potential suicidal behavior. Adolescent boys with AD and Depressive Disorder need to be identified as the high risk group for suicide prevention in the community.

Impulsivity in patients with panic disorder-agoraphobia: the role of cyclothymia

The relationship between Panic Disorder (PD) and impulsivity is not well explored. The present investigation aims to compare impulsivity, measured by different rating tools, in PD patients vs. healthy controls and to explore the influence of co-morbid Cyclothymic Disorder (CD) on the relationship between PD and impulsivity. Sixty-four subjects with PD and 44 matched controls underwent a diagnostic and symptomatological evaluations by the Mini Neuropsychiatric Interview (M.I.N.I) Plus 5.0; the Bech-Rafaelsen Depression and Mania Scale (BRDMS), the State-Trait Anxiety Inventory (STAI), the Hypomania Check List (HCL-32) and the Clinical Global Impression (CGI); the Questionnaire for the Affective and Anxious Temperament Evaluation of Memphis, Pisa, Paris and San Diego-Modified (TEMPS-M), the Separation Anxiety Sensitivity Index (SASI), the Interpersonal Sensitivity Symptoms Inventory (ISSI). Finally, psychometric and neurocognitive evaluations of impulsivity was carried out using the Barratt Impulsiveness Scale (BIS-11) and the Immediate and Delayed Memory Task (IMT/DMT). Subjects with PD were more impulsive than the controls in all the explored measures, reporting higher scores in symptomatological and temperamental scales. The comparison between PD patients with (Cyclo+) and without (Cyclo-) comorbid CD and controls showed that Cyclo+ are the most impulsive subjects in all the investigated measures and are characterized by the greatest symptomatological impairment, the highest scores in temperamental scales, and the highest levels of interpersonal sensitivity and separation anxiety. In our patients with PD, without lifetime comorbidity with major mood episodes, trait and state impulsivity may be related to the presence of comorbid cyclothymic mood instability.

Lifetime mental disorders and suicidal behaviour in South Africa

OBJECTIVE

There is relatively little data on the relationship between lifetime mental disorders and suicidal behaviour in low and middle income countries. This study examines the relationship between lifetime mental disorders, and subsequent suicide ideation, plans, and suicide attempts in South Africa.

METHOD

A national survey of 4185 South African adults was conducted using the World Health Organization Composite International Diagnostic Interview (CIDI) to generate psychiatric diagnoses and suicidal behaviour. Bivariate, multivariate and discrete-time survival analyses were employed to investigate the associations between mental disorders and subsequent suicide ideation, plans, and attempts.

RESULTS

Sixty-one percent of people who seriously considered killing themselves at some point in their lifetime reported having a prior DSM-IV disorder. Mental disorders predict the onset of suicidal ideation, but have weaker effects in predicting suicide plans or attempts. After controlling for comorbid mental disorders, PTSD was the strongest predictor of suicidal ideation and attempts. There is a relationship between number of mental disorders and suicidal behaviour, with comorbidity having significantly sub-additive effects.

CONCLUSION

Consistent with data from the developed world, mental disorders are strong predictors of suicidal behaviour, and these associations are more often explained by the prediction of ideation, rather than the prediction of attempts amongst ideators. This suggests some universality of the relevant mechanisms underlying the genesis of suicidal thoughts, and the progression to suicide attempts.

Panic disorder and school refusal

This article provides clinical and research information about panic disorder, agoraphobia, and school refusal. Proposed changes to the definition of panic disorder and agoraphobia for the Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition are outlined. Treatment of panic disorder, and school refusal in children and adolescents is also discussed.

Suicide-related behaviors and anxiety in children and adolescents: a review

This paper reviews empirical evidence of the association between suicide-related behaviors and anxiety among children and adolescents. It begins with a review of suicide-related behaviors and anxiety, discusses methodological issues related to measurement, and reviews empirical findings published since the last review of this topic in 1988. Evidence is summarized on four criteria necessary to establish anxiety as a causal risk factor for suicide-related behaviors among children and adolescents. There is consistent evidence for a significant association between anxiety and suicide-related behaviors (Criterion 1). Evidence that the influence of anxiety on suicide-related behaviors is not due to a third variable (Criterion 2) is mixed and hindered by methodological limitations. The literature is also unclear as to whether anxiety temporally precedes suicide-related behaviors (Criterion 3). Finally, this review found no evidence to support or refute anxiety's stability independent of and across instances of suicide-related behaviors (Criterion 4). Theoretical and clinical implications of these findings and directions for future research are discussed.

Panic Disorder and Suicidal Behavior

Background: Previous research has suggested that patients with panic disorder but no comorbid disorder are not at greater risk for suicidal behavior. Aims: The present study followed up patients with panic disorder in order to assess the frequency of their suicidal behavior. Methods: A sample of 281 outpatients with panic disorder, but without a comorbid psychiatric disorder, was followed up for an average of 5 years. The patients were given 6–8 weeks of cognitive therapy, and 65% were prescribed SSRIs. Results: At the time of first admission, 5 patients (1.7%) reported a previous (lifetime) suicide attempt, and 53 patients (18.2%) reported previous (lifetime) suicidal ideation (both thoughts and plans), not greatly different from the Hungarian population in general. During the follow-up period, no patient committed suicide, 2 patients attempted suicide (0.7%), and 4 patients (1.4%) reported suicidal ideation. Conclusions: This study indicates that people with panic disorders without comorbid disorders have no higher suicidal risk than the general population in Hungary. After treatment with cognitive therapy and SSRIs, 38.5% were symptom-free, and only 7.8% required continued close therapeutic contact after the follow-up period.

The Material Culture of Suicidal Fantasies

In this study, the author examined the content of impulsive suicidal fantasies among U.S. undergraduates. Of 546 participants, 45.6% reported incidents in which they fantasized about killing themselves. Most fantasies (95%) included explicit references to suicide methods, and most of those fantasies (98%) involved human-made tools or materials (e.g., drugs, cutlery, firearms). The methods reported in most suicidal fantasies seem to have been suggested by the mass media. The findings suggest that suicidal thoughts do not occur without explicit and detailed information about suicide methods involving material culture.

Mental disorders, comorbidity and suicidal behavior: results from the National Comorbidity Survey Replication

Mental disorders are among the strongest predictors of suicide attempts. However, little is known regarding which disorders that are uniquely associated with suicidal behavior because of high levels of psychiatric comorbidity. We examined the unique associations between individual disorders and subsequent suicidal behavior (suicide ideation, plans and attempts) using data from the National Comorbidity Survey Replication, a nationally representative household survey of 9282 US adults. Results revealed that approximately 80% of suicide attempters in the United States have a temporally prior mental disorder. Anxiety, mood, impulse-control and substance use disorders all significantly predict subsequent suicide attempts in bivariate analyses (odds ratios (OR)=2.7-6.7); however, these associations decrease substantially in multivariate analyses controlling for comorbidity (OR=1.5-2.3) but remain statistically significant in most cases. Disaggregation of the observed effects reveals that depression predicts suicide ideation, but not suicide plans or attempts among those with ideation. Instead, disorders characterized by severe anxiety/agitation (for example, post-traumatic stress disorder) and poor impulse control (for example, conduct disorder, substance use disorders) predict which suicide ideators who go on to make a plan or attempt. These results advance understanding of the unique associations between mental disorders and different forms of suicidal behavior. Future research must further delineate the mechanisms through which people come to think about suicide and progress from suicidal thoughts to attempts.

Are non-fatal opioid overdoses misclassified suicide attempts? Comparing the associated correlates

This paper aimed to determine whether non-fatal opioid overdose and suicide attempts are distinct behaviours by examining the histories of 1500 opioid-dependent individuals. This paper utilised data collected as part of a large retrospective case-control study. Unintentional non-fatal opioid overdoses were more common than suicide attempts (58% vs. 32%). Overall, the correlates associated with a history of attempted suicide only and non-fatal opioid overdose only were different. Drug-related risk behaviours (including high impulsivity, injection of opioids, sedative dependence) were associated with non-fatal opioid overdose; and a history of mental disorders (depression, anxiety disorder, and screening positive for borderline personality disorder (BPD+) were associated with suicide attempts. Additionally, those who reported a history of both behaviours had a more severe clinical profile including excessive drug use, psychological disorders and childhood trauma. The study concluded that non-fatal opioid overdose and attempted suicide are distinct clinically significant problems that require different approaches for prevention. Additionally, if both behaviours are reported a thorough assessment of underlying comorbid problems should be initiated by treatment services.

Headache complaints and the risk of suicidal thoughts or behaviors

The association between severe headaches and suicidal thoughts or behaviors is generally attributed to underlying depression, but it is plausible that severe headaches can lead to suicidal thoughts/behaviors, independent of the effects of psychiatric conditions. This association has been observed in only 1 previous study. Our multivariate analysis examined the longitudinal association between severe headaches and development of suicidal thoughts/behaviors over a period of 1 to 2 years among 6832 community-dwelling adults interviewed during the Epidemiologic Catchment Area Study. Severe headaches were significantly associated with developing suicidal thoughts/behaviors after adjusting for psychiatric diagnoses and demographics [adjusted odds ratio (ORa) = 1.48; 95% confidence interval (CI) = 1.04, 2.11], or additionally adjusting for interaction between anxiety and depression (ORa = 1.52; 95% CI = 1.07, 2.16). These results suggest that individuals with severe headaches should be screened for suicidal thoughts/behaviors, irrespective of the presence of a psychiatric condition.

Attempted and completed suicide in adolescence

Suicide is the third leading cause of death in adolescence, and medically serious suicide attempts occur in approximately 3% of adolescents. This review examines a number of risk factors that contribute to suicidal behavior. A prior suicide attempt is one of the best predictors of both a repeat attempt and eventual completed suicide. Depression, disruptive behavior disorders, and substance-use disorders also place adolescents at high risk for suicidal behavior, with comorbidity further increasing risk. Research on families indicates that suicidal behavior is transmitted through families. Groups at high risk for suicidal behavior include gay, lesbian, and bisexual youths, incarcerated adolescents, and homeless/runaway teens. Although abnormalities in the serotonergic system have not been consistently linked to suicidal behavior, genetic and neurobiologic studies suggest that impulsive aggression may be the mechanism through which decreased serotonergic activity is related to suicidal behavior. Findings from prevention and intervention studies are modest and indicate the need for substantially more theory-driven treatment research.

The relations of temperament and emotion self-regulation with suicidal behaviors in a clinical sample of depressed children in Hungary

Although major depressive disorder (MDD) is associated with suicidal behaviors, some depressed individuals are not suicidal and others evidence various forms of suicidality. We thus investigated whether aspects of temperament and self-regulation of dysphoria represent risk factors for DSM-IV suicidality (recurrent thoughts of death, recurrent suicidal ideation, suicidal plan, and suicide attempt) in depressed youths. Using a sample of children with MDD (N = 407; ages 7-14 years), recruited from clinical sites across Hungary, we tested the hypotheses that: (a) suicidality is related to higher levels of trait negative emotionality as well as more maladaptive and fewer adaptive regulatory responses to dysphoria and (b) as the severity of suicidal behavior increases, levels of trait negative emotionality and dysfunctional emotion regulation also increase. We also explored if other aspects of temperament relate to suicidality. Children's DSM-IV diagnoses were based on semi-structured interviews and best-estimate psychiatric consensus. Parents independently provided ratings of their children's temperament, and children separately completed an inventory of emotion regulation (ER). Using multivariate models, we failed to confirm the hypothesized relations of negative trait emotionality and suicidality, but confirmed that high maladaptive and low adaptive ER response tendencies increase the odds of suicidal behaviors, above and beyond the risk posed by depressive illness severity. Unplanned interaction terms between temperament dimensions (other than negative emotionality) and ER suggested that at some high-extremes of temperament, ER has no impact on suicidality but in their absence, adaptive ER lowers the risk of suicidality. The practical implications of the findings are discussed.

Panic and suicidal ideation and suicide attempts: results from the National Comorbidity Survey

Our objective was to determine the association between panic attacks (PAs) and panic disorder (PD), and suicidal ideation (SI) and suicide attempts (SAs) in a nationally representative sample of adults in the community. Data were drawn from the National Comorbidity Survey (n=5,877), a representative household sample of adults ages 15-54 in the United States. Multiple logistic regression analyses were used to examine the relationship between current and lifetime PA and PD and SI and SA, adjusting for differences in demographic characteristics, comorbid mental disorders (major depression, alcohol dependence, and substance dependence), childhood trauma (physical and sexual abuse), and number of lifetime mental disorders. Past-year and lifetime PA and PD were associated with increased SI (both past year and lifetime), and persisted after adjusting for comorbidity and early trauma. Associations between PA and SA were no longer statistically significant after adjusting for comorbidity. Past-year and lifetime PD were associated with lifetime SA, but these associations were no longer statistically significant after adjusting for comorbidity. Past-year and lifetime PD were associated with past-year SA, and this association persisted after adjusting for demographics, comorbidity, and number of lifetime mental disorders. These findings are consistent with previous results, and further help to clarify the relationships between panic and suicide behavior by identifying potential methodological reasons for inconsistencies in results from previous studies.

Deliberate self-harm and childhood hyperactivity in junior high school students

The present study aimed to explore the status of deliberate self-harm (DSH) among junior high-school students, and investigate the relationship between DSH and substance use and childhood hyperactivity. Subjects were 239 boys (mean age = 14.16 years, SD = 0.67) and 238 girls (14.22, 0.68) from a junior high-school in Kanagawa, Japan. A self-reporting questionnaire consisting of original questions on self-cutting, self-hitting, and tobacco and alcohol use was employed with the Wender Utah Rating Scale (WURS) for assessing childhood hyperactivity. Overall, 8.00% and 27.70% of males and 9.30% and 12.20% of females reported self-cutting and self-hitting, respectively. Regarding substance use, 33.10% and 74.10% of males and 14.30% and 63.40% of females reported tobacco and alcohol use, respectively. Comparisons of WURS scores between those with and without experience of problematic behaviors revealed that with all problematic behaviors in both genders, scores of those with experience were significantly higher than those without (P < 0.01 except for self-cutting in females, P < 0.05). The present study indicated that DSH is an important problem, even among children as young as junior high-school age. An association between DSH and childhood hyperactivity was also suggested.

Adolescent suicide and suicidal behavior

This review examines the descriptive epidemiology, and risk and protective factors for youth suicide and suicidal behavior. A model of youth suicidal behavior is articulated, whereby suicidal behavior ensues as a result of an interaction of socio-cultural, developmental, psychiatric, psychological, and family-environmental factors. On the basis of this review, clinical and public health approaches to the reduction in youth suicide and recommendations for further research will be discussed.

Panic disorder and suicidal ideation in primary care

The purpose of this study was to ascertain whether panic disorder (PD) and suicidal ideation are associated in an inner-city primary care clinic and whether this association remains significant after controlling for commonly co-occurring psychiatric disorders. We surveyed 2,043 patients attending a primary care clinic using the Primary Care Evaluation of Mental Disorders (PRIME-MD) Patient Health Questionnaire, a screening instrument that yields provisional diagnoses of selected psychiatric disorders. We estimated the prevalence of current suicidal ideation and of common psychiatric disorders including panic disorder and major depression. A provisional diagnosis of current PD was received by 127 patients (6.2%). After adjusting for potential confounders (age, gender, major depressive disorder [MDD], generalized anxiety disorder, and substance use disorders), patients with PD were about twice as likely to present with current suicidal ideation, as compared to those without PD (adjusted odds ratio [AOR] = 1.84; 95% confidence interval [CI]: 1.06-3.18; P = .03). After adjusting for PD and the above-mentioned potential confounders, patients with MDD had a sevenfold increase in the odds of suicidal ideation, as compared to those without MDD (AOR = 7.00; 95% CI: 4.42-11.08; P < .0001). Primary care patients with PD are at high risk for suicidal ideation, and patients with PD and co-occurring MDD are at especially high risk. PD patients in primary care thus should be assessed routinely for suicidal ideation and depression.

Psychological, autonomic, and serotonergic correlates of parasuicide among adolescent girls

Although parasuicidal behavior in adolescence is poorly understood, evidence suggests that it may be a developmental precursor of borderline personality disorder (BPD). Current theories of both parasuicide and BPD suggest that emotion dysregulation is the primary precipitant of self-injury, which serves to dampen overwhelmingly negative affect. To date, however, no studies have assessed endophenotypic markers of emotional responding among parasuicidal adolescents. In the present study, we compare parasuicidal adolescent girls (n=23) with age-matched controls (n=23) on both psychological and physiological measures of emotion regulation and psychopathology. Adolescents, parents, and teachers completed questionnaires assessing internalizing and externalizing psychopathology, substance use, trait affectivity, and histories of parasuicide. Psychophysiological measures including electrodermal responding (EDR), respiratory sinus arrhythmia, and cardiac pre-ejection period (PEP) were collected at baseline, during negative mood induction, and during recovery. Compared with controls, parasuicidal adolescents exhibited reduced respiratory sinus arrhythmia (RSA) at baseline, greater RSA reactivity during negative mood induction, and attenuated peripheral serotonin levels. No between-group differences on measures of PEP or EDR were found. These results lend further support to theories of emotion dysregulation and impulsivity in parasuicidal teenage girls.

Psychiatric disorders and their comorbidity in subjects with parasuicide by intentional drug overdose: prevalence and gender differences

The aims of the present study were to assess the prevalence and comorbidity of psychiatric disorders in subjects with intentional drug overdose and to explore whether there were gender differences in prevalence and comorbidity. A standardized psychiatric evaluation was performed in 100 randomly selected subjects, 18 years old and older, with intentional drug overdose referred to an emergency department. The prevalences of psychiatric morbidity and comorbidity were very high in both genders: 88% presented with at least one psychiatric diagnosis, and three-quarters presented with comorbid psychiatric disorders. Affective and anxiety disorders were the most prevalent diagnoses. One patient out of three presented with alcohol or substance misuse. Compared to females, males suffered five times more often from substance misuse and three times more often from psychotic syndrome and were three times less likely to present with anxiety disorder. When subjects are referred to hospital for intentional drug overdose, medical management should systematically involve a psychiatric assessment in order to identify not only affective and anxiety disorders, but also alcohol and substance misuse, due to the high prevalence of these disorders, especially in male subjects.

Factors associated with suicidal phenomena in adolescents: a systematic review of population-based studies

Suicidal phenomena (suicide attempts, deliberate self-harm, and suicidal plans, threats and thoughts) are common in adolescents. Identification of factors associated with these phenomena could play an important role in the development of school or community-based prevention and intervention programs. In this article, we report the results of a systematic review of the international literature on population-based studies of factors associated with suicidal phenomena in adolescents. These factors encompass psychiatric, psychological, physical, personal, familial and social domains. The quantity of evidence in support of associations between suicidal phenomena and specific factors is compared with the quantity of evidence against such associations. We conclude with a summary of the findings, including identification of new or neglected areas, which require further investigation. Methodological considerations are highlighted and implications of the findings for clinicians and other professionals concerned with prevention of suicidal behavior by adolescents are discussed.

Panic Disorder and Suicide Attempt in the National Comorbidity Survey

Clinical and some epidemiological data conflict concerning the likelihood of suicide attempt in individuals with panic disorder (PD). The purpose of this study was to illuminate the panic disorder-suicide attempt association in the National Comorbidity Survey (NCS; R. C. Kessler et al., 1994). Specifically, suicide attempt histories of those 5,872 respondents answering "yes" or "no" to the suicide attempt question were regressed against lifetime diagnostic histories. Lifetime PD history, in the presence of other disorders, was unrelated to elevated risk of suicide attempt and did not account for additional variance. PD respondents who had made a suicide attempt were characterized by Comorbidity. Epidemiological respondents with lifetime histories of PD alone are not at heightened risk for self-reported suicide attempt.

Australian and New Zealand clinical practice guidelines for the treatment of panic disorder and agoraphobia

BACKGROUND

The Royal Australian and New Zealand College of Psychiatrists is co-ordinating the development of clinical practice guidelines (CPGs) in psychiatry, funded under the National Mental Health Strategy (Australia) and the New Zealand Health Funding Authority.

METHOD

For these guidelines, the CPG team reviewed the treatment outcome literature, consulted with practitioners and patients and conducted a meta-analysis of recent outcome research.

TREATMENT RECOMMENDATIONS

Education for the patient and significant others covering: (i) the nature and course of panic disorder and agoraphobia; (ii) an explanation of the psychopathology of anxiety, panic and agoraphobia; (iii) rationale for the treatment, likelihood of a positive response, and expected time frame. Cognitive behaviour therapy (CBT) is more effective and more cost-effective than medication. Tricyclic antidepressants (TCAs) and serotonin selective reuptake inhibitors are equal in efficacy and both are to be preferred to benzodiazepines. Treatment choice depends on the skill of the clinician and the patient's circumstances. Drug treatment should be complemented by behaviour therapy. If the response to an adequate trial of a first-line treatment is poor, another evidence-based treatment should be used. A second opinion can be useful. The presence of severe agoraphobia is a negative prognostic indicator, whereas comorbid depression, if properly treated, has no consistent effect on outcome.

Social phobia, panic disorder and suicidality in subjects with pure and depressive mania

BACKGROUND

The objective of this study is to ascertain the rates of social phobia, panic disorder and suicidality in the midst of the manic state among subjects with pure and depressive mania.

METHODS

Subjects received evaluations entailing the use of serial standard clinical interviews, the Schedule for Affective Disorders and Schizophrenia (SADS) and a structured interview to determine whether they met the criteria for intra-episode social phobia (IESP) and panic disorder (IEPD). The diagnoses of major depressive disorder and mania were rendered using the Research Diagnostic Criteria. The diagnoses of IESP and IEPD were rendered using DSM-III-R criteria. Categorization as being suicidal was based on the SADS suicide subscale score.

RESULTS

Twenty-five (56.8%) subjects had pure and 19 (43.2%) subjects had depressive mania. None of the subjects with pure and 13 (68.4%) with depressive mania had IESP (P<0.0001). One (4.0%) subject with pure and 16 (84.2%) subjects with depressive mania had IEPD (P<0.0001). One (4.0%) subject with pure and 12 (63.2%) subjects with depressive were suicidal. Twelve of 13 (92.3%) subjects with depressive mania met the criteria for IESP and IEPD concurrently (P<0.0001). All were suicidal.

LIMITATIONS

The study suffers limitations imposed by small sample sizes and non-blind methods of identifying subjects with IESP, IEPD and who were suicidal.

CONCLUSIONS

Subjects with depressive but not pure mania exhibited high rates of both IESP and IEPD. Concurrence of the disorders is the rule. The findings suggest that databases disclosing a relationship between panic disorder and suicidality merit, where possible, reanalysis directed at controlling for the effect of social phobia.

Youth suicide risk and preventive interventions: a review of the past 10 years

OBJECTIVE

To review critically the past 10 years of research on youth suicide.

METHOD

Research literature on youth suicide was reviewed following a systematic search of PsycINFO and Medline. The search for school-based suicide prevention programs was expanded using two education databases: ERIC and Education Full Text. Finally, manual reviews of articles' reference lists identified additional studies. The review focuses on epidemiology, risk factors, prevention strategies, and treatment protocols.

RESULTS

There has been a dramatic decrease in the youth suicide rate during the past decade. Although a number of factors have been posited for the decline, one of the more plausible ones appears to be the increase in antidepressants being prescribed for adolescents during this period. Youth psychiatric disorder, a family history of suicide and psychopathology, stressful life events, and access to firearms are key risk factors for youth suicide. Exciting new findings have emerged on the biology of suicide in adults, but, while encouraging, these are yet to be replicated in youths. Promising prevention strategies, including school-based skills training for students, screening for at-risk youths, education of primary care physicians, media education, and lethal-means restriction, need continuing evaluation studies. Dialectical behavior therapy, cognitive-behavioral therapy, and treatment with antidepressants have been identified as promising treatments but have not yet been tested in a randomized clinical trial of youth suicide.

CONCLUSIONS

While tremendous strides have been made in our understanding of who is at risk for suicide, it is incumbent upon future research efforts to focus on the development and evaluation of empirically based suicide prevention and treatment protocols.

Suicidal behavior among urban, African American young adults

The objectives of the present study were four-fold. First, to determine the lifetime, last year, and 6-month prevalence and demographic correlates of suicidal behavior in a defined population of urban, African American young adults. Second, to determine the degree of mental health service utilization among attempters. Third, to study the comorbidity between mental disorders and suicidal behavior, along with the variation in the numbers and types of psychiatric disorders associated with attempts versus ideation only. Fourth, to examine gender differences in the psychiatric diagnoses associated with attempts and ideation. Data relevant to each of these objectives were gathered through structured interviews of 1,157 economically disadvantaged, African American young adults. Lifetime, last year, and 6-month prevalence rates for attempts were 5.3%, 1.2%, and 0.4%, respectively, whereas the lifetime and 6-month prevalence of ideation were 14% and 1.9%, respectively. Approximately two thirds of those who reported lifetime ideation, and a similar proportion of those who reported lifetime attempts, had a history of at least one lifetime psychiatric disorder. There were no gender differences in terms of the degree of risk for suicidal behavior (ideation or attempts) associated with any of the comorbid psychiatric diagnoses assessed. Despite the severity of most attempts, few attempters received mental health services in their lifetime or at the time of their most recent attempt.

An investigation of psychopathology in nonreferred suicidal and nonsuicidal adolescents

This investigation examined self-reported psychopathology in a school-based sample of 456 suicidal and nonsuicidal adolescents. The sample consisted of four groups: three at-risk for suicidal behavior based on current suicidal ideation as assessed by the Suicidal Ideation Questionnaire (SIQ; Reynolds, 1988), past suicide attempts, or both; and one nonsuicidal comparison group. Psychopathology was examined using ten scales from the Adolescent Psychopathology Scale (APS; Reynolds, 1998a) including: Major Depression, Conduct Disorder, Substance Abuse, Schizophrenia, Adjustment Disorder, Anorexia Nervosa, Borderline Personality Disorder, Obsessive-Compulsive Personality Disorder, Schizotypal Personality Disorder, and Avoidant Personality Disorder. Analyses were conducted separately for males and females using a MANOVA design that examined psychopathology severity among the four groups. Adolescents who engaged in past or current suicidal behavior had higher psychopathology severity scores compared to their nonsuicidal peers. Males with current suicidal thoughts who had attempted suicide had the highest levels of psychopathology severity compared to males in the other three groups. Females with a past suicide attempt or current suicidal ideation had higher psychopathology severity scores compared to nonsuicidal females. Results show greater psychopathology in school-based adolescents who have engaged in past and/or current suicidal behavior. The need for clinicians and mental health professionals working with at-risk youth to focus on concurrent psychopathology along with suicidal behavior is discussed.

Suicide attempts in an adolescent female twin sample

OBJECTIVE

To examine suicide attempts in an epidemiologically and genetically informative youth sample.

METHOD

3,416 Missouri female adolescent twins (85% participation rate) were interviewed from 1995 to 2000 with a telephone version of the Child Semi-Structured Assessment for the Genetics of Alcoholism, which includes a detailed suicidal behavior section. Mean age was 15.5 years at assessment.

RESULTS

At least one suicide attempt was reported by 4.2% of the subjects. First suicide attempts were all made before age 18 (and at a mean age of 13.6). Major depressive disorder, alcohol dependence, childhood physical abuse, social phobia, conduct disorder, and African-American ethnicity were the factors most associated with a suicide attempt history. Suicide attempt liability was familial, with genetic and shared environmental influences together accounting for 35% to 75% of the variance in risk. The twin/cotwin suicide attempt odds ratio was 5.6 (95% confidence interval [CI] 1.75-17.8) for monozygotic twins and 4.0 (95% CI 1.1 -14.7) for dizygotic twins after controlling for other psychiatric risk factors.

CONCLUSIONS

In women, the predisposition to attempt suicide seems usually to manifest itself first during adolescence. The data show that youth suicide attempts are familial and possibly influenced by genetic factors, even when controlling for other psychopathology.

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.
