The association between self-reported anxiety symptoms and suicidality

The Mediating Role of Insomnia Severity in the Relationship Between Anxiety Symptoms and Suicidal Ideation: A Real-World Study in a Psychiatric Inpatient Setting

ABSTRACT

Insomnia and anxiety symptoms are independent clinical variables involved in suicidal ideation in psychiatric inpatients. In this article, we investigated the relationship among insomnia severity, severity of anxiety symptoms, and suicidal ideation in a sample of psychiatric inpatients with severe mental disorders. We used a mediation model considering insomnia severity as the possible mediator of the relationship between anxiety severity and suicidal ideation. We administered the Columbia Suicide Severity Rating Scale, the Insomnia Severity Index, and the Hamilton Anxiety Rating Scale to 116 consecutive inpatients to the psychiatric unit of Sant'Andrea Hospital in Rome. The effect of anxiety symptoms was mediated by insomnia severity; patients who perceive higher anxiety symptoms were more likely to experience higher levels of insomnia and, thus, higher suicidal ideation intensity. Results showed the importance of assessing and treating both insomnia and anxiety in clinical practice.

Anxiety symptoms preceding suicide: A Swedish nationwide record review

BACKGROUND

The literature on the relationship between anxiety and suicidal behaviors is limited and findings are mixed. This study sought to determine whether physicians noted anxiety symptoms and suicidality in their patients in the weeks and months before suicide.

METHODS

Data were derived from a nationwide medical record review of confirmed suicides in Sweden in 2015. Individuals with at least one documented physician consultation in any health care setting during 12 months before suicide (N = 956) were included. Clinical characteristics were compared between decedents with and without a notation of anxiety symptoms. Odds ratios were calculated to estimate associations between anxiety symptoms and suicidality in relation to suicide proximity.

RESULTS

Anxiety symptoms were noted in half of individuals 1 week before suicide. Patients with anxiety were characterized by high rates of depressive symptoms, ongoing substance use issues, sleeping difficulties, and fatigue. After adjustment for mood disorders, the odds of having a notation of elevated suicide risk 1 week before death were doubled in persons with anxiety symptoms. Associations were similar across time periods (12 months - 1 week). Two-thirds had been prescribed antidepressants at time of death.

LIMITATIONS

Data were based on physicians' notations which likely resulted in underreporting of anxiety depending on medical specialty. Records were not available for all decedents.

CONCLUSIONS

Anxiety symptoms were common in the final week before suicide and were accompanied by increases in documented elevated suicide risk. Our findings can inform psychiatrists, non-psychiatric specialists, and GPs who meet and assess persons with anxiety symptoms.

What do older people who have attempted suicide experience? Study protocol for a qualitative meta-synthesis among older adults, family caregivers and healthcare professionals

INTRODUCTION

Attempted suicide among older adults represents a significant mental health concern that has witnessed a rising incidence within this demographic in recent years. Research indicates that attempted suicide among the older population serves as a primary risk factor for completed suicide. Consequently, the objective of this study is to provide a comprehensive overview of the prevailing factors that influence suicide attempts among older adults, thereby offering evidence to guide healthcare professionals in designing targeted interventions.

METHODS AND ANALYSIS

This study will adhere to the Joanna Briggs Institute framework and the Preferred Reporting Items for Systematic Reviews and Meta-Analyses Protocols. We will synthesise qualitative studies using a comprehensive and inclusive bibliographic search strategy. The following databases will be searched: PubMed, Embase, Web of Science, CINAHL and the Cochrane Library. The quality of the articles will be assessed using the 10-item Joanna Briggs Institute Critical Appraisal Checklist for Qualitative Research. At the same time, data extraction will be performed using the Qualitative Assessment and Review Instrument data extraction form proposed by the Joanna Briggs Institute for Evidence-Based Practice. The synthesis of findings will adhere to the principles and procedures of Thomas and Hardens' three-stage thematic synthesis approach.

ETHICS AND DISSEMINATION

Ethical approval will not be required for this study, as it solely encompasses data derived from previously published research. The findings will be disseminated through publication in a peer-reviewed journal. Moreover, the results will be presented at relevant academic conferences to guarantee that the study's outcomes reach pertinent stakeholders. This protocol is registered with the PROSPERO prospective database for systematic review.

Association between the number of hours of sleep during weekdays and suicidality among Korean adolescents: Mediating role of depressive and anxiety symptoms

BACKGROUND

Adolescent suicide is a serious concern worldwide. Sleep problems are a risk factor for suicide. Therefore, the aim of this study was to evaluate associations between sleep duration and suicidal ideation/suicide attempts and determine the extent to which depressive and anxiety symptoms mediate these associations.

METHODS

Data from 54,948 middle and high school students in South Korea were collected by the stratified cluster method through the Korea Youth Risk Behavior Web-based Survey.

RESULTS

The weighted prevalences of short and long sleep durations were 19.5 % (95 % confidence interval [CI] = 18.9-20.2) and 4.6 % (95 % CI = 4.3-4.8), respectively. Short sleep duration (<5 h/day) increased the odds of suicidal ideation and suicide attempts by 1.43 (95 % CI = 1.29-1.58) and 1.78 (95 % CI = 1.41-2.25), respectively. Long sleep duration (>9 h/day) increased the odds of suicide attempts by 1.5 (95 % CI = 1.02-2.21). Depressive and anxiety symptoms significantly mediated the relationship between sleep duration and suicidal intensity with a satisfactory goodness of fit.

LIMITATIONS

Causal relationships could not be examined due to the cross-sectional study design. Information on other psychopathologies, besides depression and anxiety, was unavailable.

CONCLUSIONS

Short sleep duration was associated with suicidal ideation and suicide attempts among Korean adolescents. Long sleep duration was associated with suicide attempts only. Both depressive and anxiety symptoms mediated the association between sleep duration and suicidal intensity; therefore, both sleep hour restoration and treatment of depressive/anxiety symptoms should be the goals of suicide prevention strategies.

Men’s anxiety, why it matters, and what is needed to limit its risk for male suicide

Anxiety disorders are the most prevalent mental health disorder experienced by men. If left untreated, anxiety is predictive of psychiatric disorders including depression and associated suicide risk. Despite the prevalence and impact of men’s anxiety, it remains largely overlooked in the field of men’s mental health. Globally, men are reported to have lower rates of anxiety disorders compared to women; however, these sex-differences do not reflect the complexity and nuance of men’s experiences. There is early evidence to suggest a male-type anxiety phenotype which may go undetected with generic diagnostic classifications. Masculine norms (i.e., stoicism, toughness, invulnerability) appear to be central to men’s experiences and expressions of anxiety as well as men’s help-seeking and coping behaviours. This is particularly concerning given anxiety increases men’s risk of physical and psychological comorbidities and suicide risk. The effective assessment, detection and treatment of men’s anxiety is therefore critical to improve mental health outcomes across the male lifespan. We propose three key recommendations for the field of men’s anxiety: (i) to develop a theoretical model surrounding men’s experiences of anxiety, (ii) broaden mental health resources, interventions and suicide prevention strategies to encompass men’s gendered experiences of anxiety (e.g., sentiments of shame, physical symptom manifestation), and (iii) utilise informal supports (i.e., friends and family) as an avenue of intervention to improve men’s anxiety outcomes. Without a substantial research agenda in men’s anxiety, we will fail to recognise and respond to men’s gendered experiences of anxiety and ultimately fail to reduce male suicides.

Suicidality and relief of depressive symptoms with intermittent theta burst stimulation in a sham-controlled randomized clinical trial

OBJECTIVES

Suicidality is a serious public health problem and is closely associated with the severity of depression. In this work, we examined the effects of accelerated intermittent theta burst stimulation (iTBS) on suicidal status, risk factors for suicide, and severity of depressive symptoms in subjects with major depressive disorder (MDD).

METHODS

We present data from a quadruple-blind (patient, care provider, investigator, rater) sham-controlled crossover randomized clinical trial. During a 6-week observation period, each participant underwent 2 weeks of stimulation - each week with 20 sessions of active or sham iTBS. A suicide score was created using a composite of individual items from Montgomery-Åsberg Depression Scale (MADRS), Hamilton Depression Scale, and Beck Depression Inventory. The severity of depression was determined by MADRS total scores. In addition, we used demographic and Columbia Suicidality Rating Scale information to assess suicide risk.

RESULTS

Among 81 participants, we observed a significant reduction in suicidality and this change was positively correlated with a change in depressive symptoms. A significant difference between active and sham iTBS provided evidence for antidepressant effects. Higher changes in levels of anxiety and impulsiviness also correlated with larger changes in suicidality.

CONCLUSIONS

As neither suicide nor other serious adverse events were evidenced, this intervention was a safe and viable procedure to reduce suicidality and severity of depressive symptoms. Moreover, we identified more pronounced anti-suicidal effects in those with higher risk profiles. Unlike MADRS, composite suicidal scores did not provide evidence of an effect between stimulation conditions in this crossover design study. Even so, based on our promising results, parallel and larger studies could contribute to a better characterization of the anti-suicidal placebo effect and the benefit of using iTBS against suicidal symptoms.

The influence of family support during endoscopic submucosal dissection on patient's anxiety

Background

Psychological problems may promote peptic ulcers. Ulcer-like wounds can be formed after gastric endoscopic submucosal dissection (ESD). The influence of family support on the healing of gastric ESD-induced ulcers remains largely undetermined.

Objective

In the present study, we aimed to assess the Hospital Anxiety and Depression Scale (HADS) scores and the incidence of post-ESD complications in patients with family support in the care process and those in the non-relative group.

Materials and methods

A total of 191 patients aged between 30 and 70 years who received gastric ESD were evaluated with the Chinese version of HADS. Differences in depression and anxiety between the two groups were compared using the chi-square test and t-test. Multivariable logistic regression models were used to examine whether anxiety and depression were the risk factors for post-ESD complications.

Results

The mean values of HADS-A (4.61 ± 2.89 vs. 5.56 ± 3.07, p = 0.042) and HADS-D (4.14 ± 3.03 vs. 4.97 ± 2.61, p = 0.048) scores were significantly lower in patients with accompanying relatives compared with those in the non-relative group. Besides, through the pre-ESD and post-ESD self-contrast, the scores of anxiety and depression in the relative-group were 0.57 and 0.56, respectively (p < 0.001), while those in the non-relative group were increased by 1.43 and 1.49, respectively (p < 0.001). Multivariable logistic regression analysis revealed that HADS-A, HADS-D scores, and age were significantly correlated with post-ESD abdominal pain (P < 0.05).

Conclusions

The occurrence and degree of adverse emotions such as psychological anxiety and depression in patients who received gastric ESD with accompanying relatives during hospitalization may were reduced, and the incidence of gastric post-ESD abdominal pain may was also decreased.

Mixed Depression: A Mini-Review to Guide Clinical Practice and Future Research Developments

The debate on mixed states (MS) has been intense for decades. However, several points remain controversial from a nosographic, diagnostic, and therapeutic point of view. The different perspectives that have emerged over the years have turned into a large, but heterogeneous, literature body. The present review aims to summarize the evidence on MS, with a particular focus on mixed depression (MxD), in order to provide a guide for clinicians and encourage the development of future research on the topic. First, we review the history of MS, focusing on their different interpretations and categorizations over the centuries. In this section, we also report alternative models to traditional nosography. Second, we describe the main clinical features of MxD and list the most reliable assessment tools. Finally, we summarize the recommendations provided by the main international guidelines for the treatment of MxD. Our review highlights that the different conceptualizations of MS and MxD, the variability of clinical pictures, and the heterogeneous response to pharmacological treatment make MxD a real challenge for clinicians. Further studies are needed to better characterize the phenotypes of patients with MxD to help clinicians in the management of this delicate condition.

Highlighting psychological pain avoidance and decision-making bias as key predictors of suicide attempt in major depressive disorder-A novel investigative approach using machine learning

OBJECTIVE

Predicting suicide is notoriously difficult and complex, but a serious public health issue. An innovative approach utilizing machine learning (ML) that incorporates features of psychological mechanisms and decision-making characteristics related to suicidality could create an improved model for identifying suicide risk in patients with major depressive disorder (MDD).

METHOD

Forty-four patients with MDD and past suicide attempts (MDD_SA, N = 44); 48 patients with MDD but without past suicide attempts (MDD_NS, N = 48-42 of whom with suicide ideation [MDD_SI, N = 42]), and healthy controls (HCs, N = 51) completed seven psychometric assessments including the Three-dimensional Psychological Pain Scale (TDPPS), and one behavioral assessment, the Balloon Analogue Risk Task (BART). Descriptive statistics, group comparisons, logistic regressions, and ML were used to explore and compare the groups and generate predictors of suicidal acts.

RESULTS

MDD_SA and MDD_NS differed in TDPPS total score, pain arousal and avoidance subscale scores, suicidal ideation scores, and relevant decision-making indicators in BART. Logistic regression tests linked suicide attempts to psychological pain avoidance and a risk decision-making indicator. The resultant key ML model distinguished MDD_SA/MDD_NS with 88.2% accuracy. The model could also distinguish MDD_SA/MDD_SI with 81.25% accuracy. The ML model using hopelessness could classify MDD_SI/HC with 94.4% accuracy.

CONCLUSION

ML analyses showed that motivation to avoid intolerable psychological pain, coupled with impaired decision-making bias toward under-valuing life's worth are highly predictive of suicide attempts. Analyses also demonstrated that suicidal ideation and attempts differed in potential mechanisms, as suicidal ideation was more related to hopelessness. ML algorithms show useful promises as a predictive instrument.

Suicide prevention in older adults

BACKGROUND

Suicide among older adults is a multifactorial problem with several interrelated factors involved that vary with age, gender and culture. The number of suicides is highest in those aged 70 years or older in almost all regions of the world. With the increase in life expectancy, and the decrease in mortality due to other causes of death, we could expect the absolute number of older adults' suicide continue increasing.

METHODS

Review of the literature on suicide protective factors of suicide among older adults.

RESULTS

Improvements on social determinants of health and the timely detection and early treatment of affective disorders are key interventions. Prevention based on community actions and training of gatekeepers may have positive impact. Community programs that promote a sense of usefulness, belonging and that contribute to preserve social integration should be encouraged. Governments should develop the improvement of retirement programs and the development of support systems. The access to general health and mental health services should be facilitated and Primary Care professionals should receive proper training to detect and manage older persons at risk. Actively promoting a culture of coping to different stages of life and to the changes imposed by the advancing of age should form the essential part of a process bringing to better successful aging avenues.

CONCLUSIONS

Suicide prevention in older adults should broaden its focus and pay attention to the many socio-environmental conditions that may be relevant in older age, especially social isolation, financial security and physical health.

Association of ADHD symptoms, depression and suicidal behaviors with anxiety in Chinese medical college students

BACKGROUND

Anxiety is one of the most common psychiatric disorder and imposes a great burden on both the individual and the society. Previous studies indicate a high comorbidity of anxiety disorders and Attention Deficit Hyperactivity Disorder (ADHD). However, few studies have examined the comorbidity of anxiety and ADHD among medical college students in mainland China. This study aimed to examine the prevalence of anxiety and the associated risk factor of anxiety disorder as well as to explore the association between ADHD symptoms, depression, suicidal behaviors and anxiety.

METHODS

A cross-sectional design was employed among 4882 medical college students who were recruited and enrolled with convenience sampling. Self-reported demographic information and clinical characteristics were collected online on a computer or through a social media app named Wechat.

RESULTS

The prevalence of anxiety in this study was 19.9%. Students with anxiety were more likely to have a poor relationship with parents, be of Han nationality, have smoking or drinking habits, have an extensive physical disorder history and have engaged in suicidal behaviors. The independent risk factors for anxiety were: smoking, physical disorder history, suicidal ideations, suicide attempts, inattention and hyperactivity. Significant associations were observed between anxiety and depression, inattention, hyperactivity, suicide plans and suicide attempts.

CONCLUSIONS

Nearly one in five medical students suffered from anxiety. The findings of this study indicate the importance of addressing both anxiety and ADHD symptoms in order to better promote mental health and the well-being of medical students as well as reduce suicidal behaviors.

Temporal Structure of Mixed States: Does Sensitization Link Life Course to Episodes?

Susceptibility to combined depressive and manic syndromes correlates strongly with arousal-related symptoms including impulsivity, anxiety and agitation. This relationship to a driven, "mixed" activation-depression state, generated by a life-long process, was described in classical times. Course of illness in mixed states includes increased episode frequency, duration, earlier onset, and association with addiction- and trauma/stress-related disorders. Mixed episodes have catecholamine and hypothalamic-pituitary-adrenocortical activity increased beyond nonmixed states of similar symptom severity. These properties resemble behavioral sensitization, where salient, survival-related stimuli (traumatic or rewarding) can generate persistently exaggerated responses with disrupted arousal and reward, with potential for suicide and other severe consequences.

Suicide risk among Veteran primary care patients with current anxiety symptoms

BACKGROUND

Although anxiety is prevalent in primary care, the association between anxiety symptoms and suicide risk remains understudied.

OBJECTIVES

This cross-sectional study aimed to (i) assess the prevalence of suicide risk among Veteran primary care patients with anxiety symptoms and (ii) compare suicide risk between patients with a positive (versus negative) depression screen.

METHODS

Participants were 182 adult primary care patients (84.6% male, Mage = 58.3 years) with current anxiety symptoms, but no psychotherapy in specialty care in the past year, at a Veterans Health Administration medical center in New York. Participants completed self-report measures of anxiety, depression and suicide risk via telephone.

RESULTS

Forty percent endorsed ≥1 suicide risk item. Suicide risk was more common among those screening positive (versus negative) for depression (50.5% versus 26.5%, χ2 (1) = 10.88; P = 0.001). Participants with a negative depression screen constituted 31% of all those with any suicide risk. Logistic regression revealed that anxiety symptom severity was not associated with suicide risk (P = 0.14) after controlling for age, sex and depression screen status (P = 0.01).

CONCLUSIONS

A substantial proportion of primary care patients with anxiety was classified as at risk for suicide, even in the absence of a positive depression screen. Primary care providers should assess suicide risk among patients with anxiety symptoms, even if the patients are not seeking specialty mental health treatment, the anxiety symptoms are not severe or do not rise to the level of an anxiety disorder, and comorbid depressive symptoms are not present.

Plasma Brain-Derived Neurotrophic Factor and Psychopathology in Attempted Suicide

BACKGROUND/AIMS

Increasing evidence suggests a link between brain-derived neurotrophic factor (BDNF) and suicidal behaviour (SB). Furthermore, decreased peripheral BDNF levels have been associated with clinical symptoms in various psychiatric disorders as well as with personality dimensions in healthy individuals. However, the relationship between BDNF and psychopathology is poorly investigated regarding SB.

METHODS

Plasma BDNF concentrations were analysed in 61 recent suicide attempters. Clinical symptoms were evaluated using the Comprehensive Psychopathological Rating Scale. Personality dimensions were assessed using the Marke-Nyman Temperament Scale.

RESULTS

Plasma BDNF correlated positively and significantly with the personality dimension Solidity but not with the other personality dimensions or with clinical symptoms.

CONCLUSION

BDNF plays an important role in the regulation of neuroplasticity and neurogenesis in humans. Our results indicate that lower BDNF concentrations are associated with higher levels of impulsiveness and changeability (low scores on the Solidity scale). Furthermore, low plasma BDNF levels may be proposed as a trait marker rather than a state marker for attempted suicide.

Exposure to suicidal behaviors: A common suicide risk factor or a personal negative life event?

BACKGROUND

Numerous suicide risk factors have been proposed but not adequately validated for epidemiology, treatment and prevention efforts.

AIMS

Exposures to suicidal behaviors (ESB), from family and friend suicide attempts and completions, were tested for validity as a suicidal risk factor and also for measurement and construct adequacy.

METHODS

An anonymous online survey yielded 713 participants (aged 18-71), who reported ESB, completed the Suicidal Affect-Behavior-Cognition Scale (SABCS), and comprised a broad spectrum on those variables.

RESULTS

Tests of dimensionality and internal consistency showed the four ESB variables (attempts/completions through family/friends) were independent and did not form a common factor or an identifiable ESB latent trait. ESB variables were, however, associated with demographic and psychiatric histories. A battery of tests revealed no meaningful associations between ESB and total suicidality or suicide risk factors (social support, depression, anxiety, stress, satisfaction with life and emotional stability). In addition, in contrast to previous reports, young adults ( n = 200; aged 18-20) showed no increased suicidality due to ESB.

CONCLUSION

Results showed no validity for ESB as a common risk factor for suicidality or other psychopathology, or as a latent trait. ESB showed evidence as a personal negative life event with individual effects and interpretations.

Social anxiety symptoms in alcohol-dependent outpatients: prevalence, severity and predictors

ABSTRACT Objectives High rates of comorbidity between social anxiety disorder (SAD) and alcohol use disorders have been reported, but the predictors of this comorbidity are poorly known and most studies involve primary SAD samples. The aims were to estimate the prevalence and severity of SAD symptoms among alcohol-dependent patients and to investigate sociodemographic and clinical factors associated with SAD comorbidity, including suicidal behaviors. Methods A cross-sectional study with 53 adults who were in treatment for alcohol dependence at a Brazilian public university outpatient service. Assessment instruments Social Phobia Inventory (SPIN), Short Alcohol Dependence Data and Beck Depression Inventory. Bivariate analyses between the categorical outcome (Probable SAD: SPIN ≥ 19) and explanatory variables were conducted. Correlates of SPIN total and subscales scores (dimensional outcomes) were also investigated. Results The diagnosis and treatment of alcohol dependence occurred, on average, 30 years after the onset of alcohol use and 39.6% of the 53 patients (37 men and 16 women) reported alleviation of social anxiety symptoms with alcohol use. Twenty-four (45.3%) patients presented probable SAD. These patients differed from non-SAD alcohol-dependent individuals by having lower income and higher frequency of depression, suicidal ideation, suicide plans and attempts. The SPIN subscales mostly associated with suicidal behaviors were social inadequacy and social inferiority. Conclusions SAD symptoms are common among help-seeking alcohol-dependent individuals and should be directly investigated and treated, since depression and suicidality are associated with this comorbidity. Prospective studies are needed to assess the impact of SAD treatment on the clinical course of alcohol dependence.

Association between weight control failure and suicidal ideation in overweight and obese adults: a cross-sectional study

Background

Korea has the highest suicide rate in the OECD and is one of the few OECD countries whose suicide rates have not decreased in recent years. To address these issues, we investigated the effects of weight control failure on suicidal ideation in the overweight and obese populations.

Methods

We performed a cross-sectional study using data from the Korea National Health and Nutrition Examination Survey (2008–2012) consisting of 6621 individuals 40 years of age or older. Logistic regression analysis was used to identify the relationship between weight control failure and suicidal ideation in the overweight and obese populations.

Results

A total of 6621 participants were analyzed in this study (overweight group: 2439; obese group: 4182). Among them, weight control failure (weight gain with weight loss efforts) was experienced in 962 obese (males 16.3 %, females 29.6 %) and 412 overweight individuals (males 9.1 %, females 23.4 %). Weight control failure was significantly associated with suicidal ideation in obese females (OR = 1.70, 95 % CI 1.21–2.39), but this association was not significant in obese males or in either sex of the overweight group.

Conclusions

Findings from this study suggest that weight control failure is associated with an increased risk of suicidal ideation among obese women. Furthermore, intervention programs that aim to address the prevalence of suicide, especially for obese women, are needed.

Use of antiepileptic or benzodiazepine medication and suicidal ideation--The Northern Finland Birth Cohort 1966

Both antiepileptic drugs (AEDs) and benzodiazepines (BZDs) have previously been associated with an increased risk of suicidality. Our aim was to study the association between the use of conventional AEDs and BZDs and suicidal ideation in a large population-based cohort. Information on the medications used in the Northern Finland Birth Cohort 1966 was collected from the subjects at the age of 31 years, using a postal questionnaire (N=8211). The presence of suicidal ideation and other symptoms of depression and anxiety was assessed via the Hopkins Symptom Checklist - 25 questionnaire. The associations between medications and suicidal ideation were studied in different diagnostic groups and adjusted for symptoms of depression and anxiety. No difference was observed in suicidal ideation between AED users (n=54) and nonusers (n=8157). Subjects using BZDs (n=147) had greater suicidal ideation compared with nonusers (n=8064). Antiepileptic drug and benzodiazepine users more often exhibited other depression and anxiety symptoms. After adjustment for these symptoms, both AED and BZD users had less suicidal ideation compared with nonusers. In conclusion, in this population-based cohort, neither the use of AEDs nor that of BZDs was found to be associated with increased suicidal ideation when the symptoms of depression and anxiety were taken into account.

Effects of mindfulness-based cognitive therapy on self-reported suicidal ideation: results from a randomised controlled trial in patients with residual depressive symptoms

INTRODUCTION

The aim of the present study was to investigate the effects of mindfulness-based cognitive therapy (MBCT) on suicidal ideation in an open-label randomised controlled trial of patients with residual depressive symptoms. Furthermore, this study aimed at examining whether an effect of MBCT on suicidal ideation was dependent on a reduction in depression severity, worry and rumination, or an increase in mindfulness.

METHODS

One hundred and thirty participants were randomised to a treatment arm (treatment as usual plus MBCT) or a wait list arm. Change in depression, change in worry, change in rumination and change in mindfulness were entered as covariates in a repeated measures ANOVA in order to assess to what degree MBCT-induced changes in suicidal ideation were independent from changes in these parameters.

RESULTS

There was a significant group×time (pre vs. post) interaction on suicidal ideation indicating a significant reduction of suicidal ideation in the MBCT group, but not in the control group. The interaction remained significant after addition of the above covariates. Change in worry was the only covariate associated with change in suicidal ideation, causing a moderate reduction in the interaction effect size.

CONCLUSIONS

The results suggest that MBCT may affect suicidal ideation in patients with residual depressive symptoms and that this effect may be mediated, in part, by participants' enhanced capacity to distance themselves from worrying thoughts.

Use of antidepressant medication and suicidal ideation-the Northern Finland Birth Cohort 1966

OBJECTIVE

The aim was to study the association between use of antidepressant medication and suicidal ideation in different diagnostic groups in a large population-based cohort.

METHODS

Information on prescribed drugs within the Northern Finland Birth Cohort 1966 was collected at the age of 31 years with postal questionnaire (N= 8218). The presence of suicidal ideation was assessed via the Hopkins Symptom Checklist-25 questionnaire. We studied associations between suicidal ideation and antidepressant medication in various diagnostic and symptom groups, and it adjusted for symptoms of depression and anxiety.

RESULTS

Suicidal ideation was associated with the use of antidepressant medication in all diagnostic groups, but the association disappeared with adjustment for other symptoms of depression and anxiety. Subjects who reported insomnia and used antidepressants had suicidal ideation more commonly than did subjects who were not using antidepressants even when other symptoms were adjusted for (p = 0.02). There were no statistically significant differences between antidepressant groups or doses.

CONCLUSION

In a large unselected cohort, antidepressant medication was not associated with increased suicidal ideation when other symptoms of depression and anxiety were taken into account. The assessment of insomnia might be useful for identifying individuals liable to have increased suicidal ideation while on antidepressant medication.

Reflections of older adults on the process preceding their suicide attempt: a qualitative approach

The study explores the reflections of older adults on the process preceding their suicide attempt. Data were gathered using in-depth interviews with eight older inpatients who had attempted suicide. Grounded theory methodology was used for data analysis. They described their life and the self as disrupted after experiencing a loss, loneliness, loss of control, and unwillingness to continue living the current life. The findings suggest that the concurrence of these constructs precedes a suicide attempt in later life.

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.

Fear of dying in panic attacks predicts suicide attempt in comorbid depressive illness: prospective evidence from the National Epidemiological Survey on Alcohol and Related Conditions

CONTEXT

As a group, comorbid anxiety disorders among depressed persons have consistently been found to increase risk of suicide attempt (SA). Growing evidence supports the link between panic attacks (PAs) and suicidality, but prospective evidence is limited and the nature of the linkage remains unclear. The positive-feedback model of suicide suggests that PAs eliciting catastrophic cognitions may drive SA.

OBJECTIVE

To prospectively examine the relationship between PAs, panic symptoms and suicidality in individuals meeting DSM-IV criteria for past-year major depressive episodes in a large epidemiological study.

METHODS

In data on 2,864 participants of the National Epidemiological Survey on Alcohol and Related Conditions (NESARC) wave 1 and 2 surveys with depressive disorders, the associations of PAs and panic symptoms with subsequent suicidal ideation (SI) and SAs were assessed using logistic regression.

RESULTS

Past-year PAs in wave 1 significantly increased odds for subsequent SI and attempt in the 3-year follow-up interval; however, in multivariate analyses, PAs were not a significant predictor, but PAs featuring fear of dying were. Further, among subjects with PAs, fear of dying during a PA increased the odds of subsequent SA sevenfold, even after controlling for comorbid disorders, demographic factors, and other PA symptoms.

CONCLUSION

PAs characterized by prominent morbid catastrophic cognitions may mediate the transition to SIs and SAs in subjects with depressive episodes. Presence of these symptoms in clinical settings may serve as a warning sign for future suicidality.

The association between anxiety disorders and suicidal behaviors: a systematic review and meta-analysis

BACKGROUND

Although anxiety has been proposed to be a potentially modifiable risk factor for suicide, research examining the relationship between anxiety and suicidal behaviors has demonstrated mixed results. Therefore, we aimed at testing the hypothesis that anxiety disorders are associated with suicidal behaviors and evaluate the magnitude and quality of supporting evidence.

METHODS

A systematic literature search of multiple databases was conducted from database inception through August 2011. Two investigators independently reviewed and determined the eligibility and quality of the studies based upon a priori established inclusion criteria. The outcomes of interest were suicidal ideations, suicide attempts, completed suicides, and a composite outcome of any suicidal behaviors. We pooled odds ratios from the included studies using random effects models.

RESULTS

Forty-two observational studies were included. The studies had variable methodological quality due to inconsistent adjustment of confounders. Compared to those without anxiety, patients with anxiety were more likely to have suicidal ideations (OR = 2.89, 95% CI: 2.09, 4.00), attempted suicides (OR = 2.47, 95% CI: 1.96, 3.10), completed suicides (OR = 3.34, 95% CI: 2.13, 5.25), or have any suicidal behaviors (OR = 2.85, 95% CI: 2.35, 3.46). The increase in the risk of suicide was demonstrated for each subtype of anxiety except obsessive-compulsive disorder (OCD). The quality of this evidence is considered low to moderate due to heterogeneity and methodological limitations.

CONCLUSIONS

This systematic review and meta-analysis provides evidence that the rates of suicides are higher in patients with any type of anxiety disorders excluding OCD.

Impact of psychotropic drugs on suicide and suicidal behaviors

OBJECTIVE

To examine the impact of psychotropic drugs on suicide and suicidal behaviors in bipolar disorders.

METHODS

A Medline search of articles published from January 1960 to January 2013 was performed using relevant keywords to identify studies examining the relationship of psychotropic drugs to suicidal behaviors. The publications were further reviewed for relevant references and information. Additionally, the US Food and Drug Administration Center for Drug Evaluation Research website was searched.

RESULTS

The available studies used differing methodologies, making interpretation of the findings difficult. Studies suggest that antidepressants may increase suicidal risk in bipolar disorder, this possibly being related to the induction of broadly defined mixed states. There is no evidence that antiepileptic drugs as a class increase suicidal risk in patients with bipolar disorder. Only lithium provides convincing data that it reduces the risk of suicide over the long term. There is little known regarding the effects of antipsychotics, as well as anti-anxiety and hypnotic drugs, on suicidal behavior.

CONCLUSIONS

The available evidence for the impact of psychotropics on suicidal risk in patients with bipolar disorder is largely methodologically flawed and, except for a few instances, clinically not useful at this point. Adequately powered, prospective randomized controlled studies are needed to assess the impact of each class of psychotropic and each psychotropic as well as common combination therapies. Until such studies have been carried out, clinicians are urged to exercise caution in using these drugs and rely on the traditional means of carefully assessing and monitoring patients with bipolar disorder who are at high risk for suicide.

Acceptance and Commitment Therapy with Older Adults: Rationale and Considerations

Older adults are the fastest growing segment of the population. With these changing demographics, mental health professionals will be seeing more older clients. Additionally, older adults are an underserved population in that most older adults in need of mental health services do not receive treatment. Thus, it is essential that treatments for mental and behavioral health problems are empirically supported with older adults and that mental health professionals are aware of the special needs of older adult populations. Acceptance and Commitment Therapy (ACT) is an emerging approach to the treatment of distress. The purpose of this article is to provide a rationale for using ACT with older adults based on gerontological theory and research. We also review research on ACT-related processes in later life. We present a case example of an older man with depression and anxiety whom we treated with ACT. Finally, we describe treatment recommendations and important adaptations that need to be considered when using ACT with older adults and discuss important areas for future research.

The role of impulsivity in the relationship between anxiety and suicidal ideation

BACKGROUND

The purpose of the present study was to examine the degree to which trait and cognitive (looming cognitive style) measures of anxiety are associated with suicidal ideation (SI), as well as whether trait and cognitive (time misperception) measures of impulsivity moderate the association between these variables.

METHODS

The sample included 100 undergraduate students (72% female) who completed the Spielberger State-Trait Anxiety Inventory, Looming Maladaptive Style Questionnaire, Barratt Impulsiveness Scale, Time Paradigm Version 1.0 Task, Beck Scale for Suicidal Ideation, and the Brief Symptom Inventory.

RESULTS

Trait anxiety and looming cognitive style were found to be positively associated with SI. Further, both trait impulsivity and time misperception moderated the association between these variables and SI, but in a different manner. Consistent with study hypotheses, among those high in trait anxiety, greater overestimation of time was associated with a higher likelihood of SI. Contrary to study hypotheses, among those low in trait anxiety, high trait impulsivity was associated with a greater likelihood of SI. The same pattern of results was found when looming cognitive style served as the independent variable.

LIMITATIONS

The use of a cross-sectional design limits the ability to determine the temporal relationship of the study variables. Further, the sample included predominantly Caucasian undergraduates and thus study results may not generalize to other populations.

CONCLUSIONS

Clinically, results suggest that high trait anxiety, looming cognitive style, time misperception, and trait impulsivity may be important risk factors for SI among college students and thus should be assessed when students present for treatment. Treatments that focus on problem solving, cognitive restructuring, and affect regulation strategies may help decrease anxiety and impulsivity, which in turn may help reduce the likelihood of suicidal thoughts.

Anxiety symptoms and suicidal feelings in a population sample of 70-year-olds without dementia

BACKGROUND

The role of anxiety in late-life suicidal behavior has received relatively little attention. The aim was to explore the association between anxiety symptoms and suicidal feelings in a population sample of 70-year-olds without dementia, and to test whether associations would be independent of depression.

METHODS

Face-to-face interviews (N = 560) were carried out by psychiatric nurses and past month symptoms were rated with the Comprehensive Psychopathological Rating Scale (CPRS). The Brief Scale for Anxiety (BSA) was derived from the CPRS to quantify anxiety symptom burden. Past month suicidal feelings were evaluated with the Paykel questions.

RESULTS

Anxiety symptom burden was associated with suicidal feelings and the association remained after adjusting for major depression. One individual BSA item (Inner tension) was independently associated with suicidal feelings in a multivariate regression model. The association did not remain, however, in a final model in which depression symptoms replaced depression diagnosis.

CONCLUSIONS

Results from this population study suggest an association between anxiety and suicidal feelings in older adults. The role of anxiety and depression symptoms needs further clarification in the study of suicidal behavior in late life.

Emergency room validation of the revised Suicide Trigger Scale (STS-3): a measure of a hypothesized suicide trigger state

BACKGROUND

The Suicide Trigger Scale (STS) was designed to measure the construct of an affective 'suicide trigger state.' This study aims to extend the inpatient setting validation study of the original Suicide Trigger Scale version 2 to the revised Suicide Trigger Scale version 3 (STS-3) in an acute psychiatric emergency room setting.

METHODS

The 42-item STS-3 and a brief psychological test battery were administered to 183 adult psychiatric patients with suicidal ideation or attempt in the psychiatric emergency room, and re-administered to subjects at 1 year follow up. Factor analysis, linear and logistic regressions were used to examine construct structure, divergent and convergent validity, and construct validity, respectively.

RESULTS

The STS-3 demonstrated strong internal consistency (Cronbach's alpha 0.94). Factor analysis yielded a three-factor solution, which explained 43.4% of the variance. Principal axis factor analysis was used to identify three reliable subscales: Frantic Hopelessness, Ruminative Flooding, and Near-Psychotic Somatization (Cronbach's alphas 0.90, 0.80, and 0.76, respectively). Significant positive associations were observed between Frantic Hopelessness and BSI depression and anxiety subscales, between Ruminative Flooding and BSI anxiety and paranoia subscales, and Near Psychotic Somatization and BSI somatization subscales. Suicidal subjects with suicide attempt history had mean scores 7 points higher than those without history of suicide attempts. Frantic hopelessness was a significant predictor of current suicide attempt when only attempts requiring at least some medical attention were considered.

CONCLUSION

The STS-3 measures a distinct clinical entity, provisionally termed the 'suicide trigger state.' Scores on the STS-3 or select subscales appear to relate to degree of suicidality in terms of severity of ideation, history of attempt, and presence of substantive current attempts. Further study is required to confirm the factor structure and better understand the nature of these relations.

Use of antipsychotic medication and suicidality--the Northern Finland Birth Cohort 1966

In addition to psychoses, antipsychotic drugs are nowadays also prescribed for other psychiatric disturbances, such as mood disorders. We wanted to find out whether there is any association between the use of antipsychotic drugs and suicidality in cases of psychotic and non-psychotic disorders. Our sample was the population-based Northern Finland 1966 Birth Cohort. Information on the use of prescribed drugs was collected in 1997 from the nationwide medication register and with a postal questionnaire (N = 8218). The presence of suicidal ideation was assessed cross-sectionally using the Symptom Check List-25 questionnaire. We studied associations between suicidal ideation, adjusted for symptoms of depression and anxiety, and antipsychotic medication in different diagnostic groups (schizophrenia, other psychosis and no psychosis). Individuals receiving antipsychotic medication (n = 70, 0.9%) had in general more suicidal ideation regardless of diagnostic group, although the associations diminished when taking other symptoms into account. There were no statistically significant differences between those taking typical and atypical antipsychotics. In the non-psychotic group, higher antipsychotic doses were associated with more suicidal ideation even when adjusted for symptoms of depression and anxiety (p < 0.05). In the cases of schizophrenia or other forms of psychosis, no such associations were observed. Our results suggest that one should take suicidal ideation into account when prescribing antipsychotic medication, especially for off-label use.

Prevalence of suicidal ideation and related risk factors in the German general population

The present study aimed to determine the prevalence of suicidal ideation in a representative sample of the German general population and examined its relation to potential risk factors. The study sample consisted of 2509 persons. Mean age was 49.4 years (SD, 18.2 years; 55.8% women). Participants filled in the Hospital Anxiety and Depression Scale and two items from the Rasch-based Depression Screening measuring suicidal ideation. Suicidal ideation was reported by 8.0% (n = 211) of all participants. People reporting suicidal ideation were less likely to be married or living together with a partner and to have children aged 6 to 13 years and were more likely to be divorced. They reported significantly higher levels of a depressive syndrome (t = 17.78; p < 0.001) and an anxiety syndrome (t = 18.43; p < 0.001). The study showed high point prevalence for suicidal ideation in the general German population. In concordance with results from similar studies in other countries, living alone and reporting anxious and depressive syndromes was associated with suicidal ideation.

Do depression and anxiety converge or diverge in their association with suicidality?

Depressive disorders have been strongly linked to suicidality, but the association with anxiety disorders is less well established. This exploratory study aims to examine whether anxiety and depressive disorders are both independent risk factors for suicidal ideation and attempted suicide, and additionally examined the role of specific clinical characteristics (disorder type, severity, duration, onset age) in suicidality. Data are from 1693 persons with a current (6-month) CIDI based depressive or anxiety disorder and 644 healthy controls participating in the baseline measurement of the Netherlands Study of Depression and Anxiety, which is an existing dataset. Suicidal ideation in the week prior to baseline and attempted suicide ever in life were assessed. Results showed that compared to persons with only an anxiety disorder, persons with a depressive disorder were at significantly higher risk to have current suicidal ideation or a history of attempted suicide. When examining the association between type of disorder and suicidality the odds ratio for MDD was significantly higher than those for the separate anxiety disorders. Although depression and anxiety severity were univariate risk indicators for suicidal ideation and attempted suicide, only depression severity remained a risk indicator for suicidal ideation and attempted suicide in multivariate analyses. Additional risk indicators were an early age at disorder onset for both suicidal ideation and attempted suicide, male gender for suicidal ideation and lower education for attempted suicide. These findings suggest that although anxiety and depression tend to converge in many important areas, they appear to diverge with respect to suicidality.

Does anxiety increase impulsivity in patients with bipolar disorder or major depressive disorder?

The objective of this study was to examine whether anxiety increases impulsivity among patients with bipolar disorder (BPD) and major depressive disorder (MDD). Subjects comprised 205 BPD (mean age ± SD 36.6 ± 11.5 y; 29.3% males) and 105 with MDD (mean age ± SD 38 ± 13.1 y; 29.5% males) diagnosed using the DSM-IV-SCID. Impulsivity was assessed with the Barratt Impulsivity Scale and anxiety with the Hamilton Anxiety Rating Scale. Comorbid anxiety disorders were present in 58.9% of the BPD and 29.1% of MDD. BPD were significantly more impulsive than MDD (p < 0.001), and both BPD and MDD subjects showed significantly higher impulsivity when anxiety was present either as a comorbidity (p = 0.010) or as a symptom (p = 0.011). Impulsivity rose more rapidly with increasing anxiety symptoms in MDD than in BPD. The presence of anxiety, either as a comorbid disorder or as current anxiety symptoms, is associated with higher impulsivity in subjects with either BPD or MDD.

Thought suppression is associated with psychological distress in homebound older adults

BACKGROUND

Engaging in thought suppression as a coping mechanism has been associated with higher rates of anxiety and depressive disorders in younger adults. Homebound older adults are a population of elders experiencing poor health and high levels of depression and anxiety. It is unclear the extent to which psychological factors, such as thought suppression, are associated with distress, given that their health and disability status may be more salient. The aim of this study was to investigate thought suppression in relation to anxiety and depressive symptoms in homebound older adults.

METHODS

Participants (N = 142) were clients of home-based case management services delivered by aging service agencies in Florida. Participants were administered a research interview that included the White Bear Suppression Inventory, Structured Clinical Interview for DSM-IV Diagnosis (SCID), Brief Symptom Inventory-18 (BSI-18), and Modified Mini-Mental Status Examination (3MS). Case managers provided standard assessments containing functional and health status of the participant.

RESULTS

After controlling for physical health and cognitive functioning, thought suppression was significantly associated with higher likelihood of clinically significant somatic, depressive, and anxiety symptoms on the BSI-18. Thought suppression was also associated with meeting criteria for a SCID depressive or adjustment disorder. Engaging in thought suppression was associated with worse mental health in this sample of homebound older adults even after taking into account physical health, disability, and cognitive functioning.

CONCLUSIONS

These findings suggest the need to develop and test interventions that may address thought suppression as a coping mechanism.

Pollen counts and suicide rates. Association not replicated

OBJECTIVE

  To replicate a previously reported association between pollen counts and county suicide rates in the continental United States, across space and time.

METHOD

  The authors evaluated the relationship between airborne pollen counts and suicide rates in 42 counties of the continental United States, containing a pollen-counting station participating in the Aeroallergen Monitoring Network in the United States (N = 120,076 suicides), considering years' quarter, age group, sex, race, rural/urban location, number of local psychiatrists, and median household income, from 1999 to 2002. The county-level effects were broken into between-county and within-county.

RESULTS

  No within-county effects were found. Between-county effects for grass and ragweed pollen on suicide rates lost statistical significance after adjustment for median income, number of psychiatrists, and urban vs. rural location.

CONCLUSION

  Future research is necessary to reappraise the previously reported relationship between pollen levels and suicide rates that may have been driven by socioeconomic confounders.

A Study on Correlation between Anxiety Symptoms and Suicidal Ideation

OBJECTIVE

In South Korea, the number of deaths from suicide has increased in the last two decades, and suicide has become both a social and political problem. In this study, after controlling the variables influencing suicidal ideation, it was expected that it would be determined if anxiety symptoms are independently related to suicidal ideation.

METHODS

Data were obtained from 327 psychiatric outpatients accomplished a self-reported questionnaire that included sociodemographic characteristics and clinical variables as well as self-rating scales for measuring the severity of one's anxiety, depression, and suicidal ideation. Logistic-regression analyses were used to determine the correlation between anxiety symptoms and significant suicidal ideation, adjusting for covariates.

RESULTS

The patients with significant suicidal ideation were shown to be less educated, unemployed, never married, divorced, or separated by death, or living alone, and were shown to have a lower income, a drinking habit, a higher number of past suicide attempts, and more family members who committed suicide, than the patients without significant suicidal ideation. After adjusting the covariates influencing significant suicidal ideation, anxiety symptoms were associated with significant suicidal ideation. However, after adjusting for depressive symptoms, only the trait anxiety was associated with significant suicidal ideation.

CONCLUSION

These findings suggest that anxiety symptoms are an independent risk factor for suicidal ideation. Clinicians may thus use anxiety symptoms for the screening examination when evaluating suicidal ideation and risk, and will have to actively evaluate and treat the anxiety symptoms of patients with suicidal tendencies.

History of suicide attempt in male substance-dependent inpatients and relationship to borderline personality features, anger, hostility and aggression

The aim of this study was to investigate the relationship between severity of borderline personality features and history of suicide attempt (HSA) in male substance-dependent inpatients and the effect of anger, hostility and aggression on this relationship. Further, the effect of some variables that may be related to suicide and/or borderline personality, such as age at inception of regular substance use, substance of dependence (alcohol/drug), depression, and both state and trait anxiety, were controlled. Participants were 200 consecutively admitted male substance-dependent inpatients. Patients were investigated with the Borderline Personality Inventory (BPI), the Buss-Perry Aggression Questionnaire (AQ), the Beck Depression Inventory (BDI) and the State-Trait Anxiety Inventory (STAI). Among substance-dependent inpatients, 33.0% (n=66) were identified as the group with HSA. Mean scores employment status, marital status and duration of education did not differ between groups, whereas current age and age at onset of regular substance use were lower in group with HSA. Mean scores of BPI, AQ and its subscales (anger, hostility and physical/verbal aggression), BDI and STAI were higher in the HSA group. In addition, the rates of drug dependency and borderline personality disorder were higher in this group. The severity of borderline personality symptoms was highly correlated with subscales of the AQ, depression and anxiety, whereas it was negatively correlated with age at onset of regular substance use. The severity of anger and borderline personality features predicted HSA in the logistic regression model. Results suggest that, to reduce the risk of suicide attempt among substance-dependent patients, the feeling of anger must be the target of evaluation and treatment among those with borderline personality features.

The anxiety disorders and suicidal ideation: accounting for co-morbidity via underlying personality traits

BACKGROUND

The anxiety disorders are robust correlates/predictors of suicidal ideation, but it is unclear whether (a) the anxiety disorders are specifically associated with suicidal ideation or (b) the association is due to co-morbidity with depression and other disorders. One means of modeling co-morbidity is through the personality traits neuroticism/negative emotionality (N/NE) and extraversion/positive emotionality (E/PE), which account for substantial shared variance among the internalizing disorders. The current study examines the association between the internalizing disorders and suicidal ideation, after controlling for co-morbidity via N/NE and E/PE.

METHOD

The sample consisted of 327 psychiatric out-patients. Multiple self-report and interview measures were collected for internalizing disorders [depression, generalized anxiety disorder (GAD), post-traumatic stress disorder (PTSD), social anxiety, panic and specific phobia] and suicidal ideation, as well as self-report measures for N/NE and E/PE. A model was hypothesized in which each disorder and suicidal ideation was regressed on N/NE, and depression and social anxiety were regressed on E/PE. Structural equation modeling (SEM) was used to examine the unique association of suicidality with each disorder, beyond shared variance with N/NE and E/PE.

RESULTS

The hypothesized model was an acceptable fit to the data. Although zero-order analyses indicated that suicidal ideation was moderately to strongly correlated with all of the disorders, only depression and PTSD remained significantly associated with suicidal ideation in the SEM analyses.

CONCLUSIONS

In a latent variable model that accounts for measurement error and a broad source of co-morbidity, only depression and PTSD were uniquely associated with suicidal ideation; panic, GAD, social anxiety and specific phobia were not.

Distinguishing the relevant features of frequent suicide attempters

BACKGROUND

In spite of the high prevalence of suicide behaviours and the magnitude of the resultant burden, little is known about why individuals reattempt. We aim to investigate the relationships between clinical risk factors and the repetition of suicidal attempts.

METHODS

1349 suicide attempters were consecutively recruited in the Emergency Room (ER) of two academic hospitals in France and Spain. Patients were extensively assessed and demographic and clinical data obtained. Data mining was used to determine the minimal number of variables that blinded the rest in relation to the number of suicide attempts. Using this set, a probabilistic graph ranking relationships with the target variable was constructed.

RESULTS

The most common diagnoses among suicide attempters were affective disorders, followed by anxiety disorders. Risk of frequent suicide attempt was highest among middle-aged subjects, and diminished progressively with advancing age of onset at first attempt. Anxiety disorders significantly increased the risk of presenting frequent suicide attempts. Pathway analysis also indicated that frequent suicide attempts were linked to greater odds for alcohol and substance abuse disorders and more intensive treatment.

CONCLUSIONS

Novel statistical methods found several clinical features that were associated with a history of frequent suicide attempts. The identified pathways may promote new hypothesis-driven studies of suicide attempts and preventive strategies.

Review of the safety, efficacy, and side effect profile of asenapine in the treatment of bipolar 1 disorder

OBJECTIVE

Asenapine is approved for acute manic and mixed states in bipolar disorder. The objective is to review the efficacy of asenapine in bipolar disorder, with a particular focus on acceptability and adherence to treatment.

METHODS

FIVE CLINICAL TRIALS WERE CONDUCTED IN BIPOLAR DISORDER MANIC OR MIXED STATES: two 3-week trials (n = 976) comparing asenapine to placebo, a 9-week extension (n = 504), and a 40-week extension (n = 107). One trial was conducted comparing asenapine to placebo (n = 326) as adjunctive therapy for subjects with an incomplete response to lithium or valproate. All trials were conducted in the USA and internationally.

RESULTS

Asenapine was found to be efficacious for manic and mixed states in bipolar disorder compared with placebo control, and compares equally well to olanzapine on efficacy measures after 3 weeks of treatment. Asenapine was not found to be efficacious for depression symptoms. Common asenapine side effects in the 40-week extension trial were sedation, insomnia, and dizziness, and 31% reported clinically significant weight gain, compared with 55% reporting clinically significant weight gain with olanzapine. Additionally, 18% had clinically significant changes in fasting blood glucose levels compared to 22% of those on olanzapine. In terms of patient acceptability, one concern may be sublingual administration requiring no liquids or food for 10 minutes after dosing and a twice-daily regimen. Suggestions about addressing barriers to adherence and acceptability are provided.

CONCLUSION

Asenapine is a promising new medication in bipolar disorder. Asenapine in the long-term has a more favorable weight gain profile compared to olanzapine. No benefit was seen for depression symptoms, a major patient-reported concern. Some side effects do not remit after the short-term trials in at least 10% of patients.

Construct development: The Suicide Trigger Scale (STS-2), a measure of a hypothesized suicide trigger state

BACKGROUND

This study aims to develop the construct of a 'suicide trigger state' by exploring data gathered with a novel psychometric self-report instrument, the STS-2.

METHODS

The STS-2, was administered to 141 adult psychiatric patients with suicidal ideation. Multiple statistical methods were used to explore construct validity and structure.

RESULTS

Cronbach's alpha (0.949) demonstrated excellent internal consistency. Factor analyses yielded two-component solutions with good agreement. The first component described near-psychotic somatization and ruminative flooding, while the second described frantic hopelessness. ROC analysis determined an optimal cut score for a history of suicide attempt, with significance of p < 0.03. Logistic regression analysis found items sensitive to history of suicide attempt described ruminative flooding, doom, hopelessness, entrapment and dread.

CONCLUSIONS

The STS-2 appears to measure a distinct and novel clinical entity, which we speculatively term the 'suicide trigger state.' High scores on the STS-2 associate with reported history of past suicide attempt.

Anxiety disorders among methamphetamine dependent adults: association with post-treatment functioning

Although anxiety is one of the most prominent psychiatric complaints of methamphetamine (MA) users, little is known about the association between anxiety disorders and treatment outcomes in this population. Using data from 526 adults in the largest psychosocial clinical trial of MA users conducted to date, this study examined psychiatric, substance use, and functional outcomes of MA users with concomitant anxiety disorders 3 years after treatment. Anxiety disorders were associated with poorer alcohol and drug use outcomes, increased health service utilization, and higher levels of psychiatric symptomatology, including suicidality. Addressing anxiety symptoms and syndromes in MA users may be helpful as a means of optimizing treatment outcomes.

Rapid resolution of suicidal ideation after a single infusion of an N-methyl-D-aspartate antagonist in patients with treatment-resistant major depressive disorder

OBJECTIVE

Suicidal ideation is a medical emergency, especially when severe. Little research has been done on pharmacologic interventions that could address this problem. Ketamine, an N-methyl-D-asparate antagonist, has been reported to have antidepressant effects within hours. We examined the effects of a single dose of ketamine on suicidal ideation in subjects with treatment-resistant major depressive disorder (MDD).

METHOD

Thirty-three subjects with DSM-IV-diagnosed MDD received a single open-label infusion of ketamine (0.5 mg/kg) and were rated at baseline and at 40, 80, 120, and 230 minutes postinfusion with the Scale for Suicide Ideation (SSI), the Montgomery-Åsberg Depression Rating Scale, the Hamilton Depression Rating Scale, and the Beck Depression Inventory. The study was conducted between October 2006 and January 2009.

RESULTS

Suicidal ideation scores decreased significantly on the SSI as well as on the suicide subscales of other rating instruments within 40 minutes; these decreases remained significant through the first 4 hours postinfusion (P < .001). Ten subjects (30%) had an SSI score ≥ 4 at baseline; all these scores dropped below 4 (9 dropped by 40 minutes and 1 by 80 minutes). For those patients with a starting score below 4 on the SSI, only 1 reached a score of 4. Depression, anxiety, and hopelessness were significantly improved at all time points (P < .001).

CONCLUSIONS

Suicidal ideation in the context of MDD improved within 40 minutes of a ketamine infusion and remained improved for up to 4 hours postinfusion. Future studies with ketamine in suicidal ideation are warranted due to the potential impact on public health.

Gender differences in risk assessment of death wishes and suicidal ideation in the community: results from the KORA Augsburg F3 study with 3079 men and women, 35 to 84 years of age

Understanding factors associated with death wishes and suicidal ideation (SID) may help to improve identification of subjects at risk in the general population. We assessed SID in a population-based sample of 3079 subjects, 35 to 84 years and examined multiple sex- and age-adjusted affective and bio-behavioral covariates. Anxiety and a high level of somatic complaints, particularly dyspnea, contributed to the SID risk. However, the clinical picture of subjects suffering from SID was dominated by a 6-fold adjusted increased risk of a depressive syndrome followed by impaired self perceived health (3-fold risk) in both sexes. In men, unemployment status and living alone also increased SID risk substantially. These factors open new insights for our understanding of the multifaceted etiology of suicide risks offering new strategies for early detection of subjects at risk.
