Suicidal ideation and anxiety disorders: elevated risk or artifact of comorbid depression?

Australian men's help-seeking intentions for anxiety symptoms: The impact of masculine norm conformity and gender role conflict

Research highlights a discrepancy between the number of men experiencing mental illness and those seeking professional help, particularly for anxiety. Conformity to masculine norms (CMN) and gender role conflict (GRC) have been recognised as barriers to men's mental health help-seeking, but few studies have examined these relationships for anxiety. This study aimed to examine the relationship between anxiety severity and help-seeking intentions in Australian men, and the additional impact of CMN and GRC. A total of 610 Australians aged 18-89 years (M = 46.02, SD = 17.14) participated in an online survey, which included demographic information and four standardised questionnaires measuring anxiety, help-seeking intentions, CMN, and GRC. CMN but not GRC was found to fully mediate the relationship between anxiety severity and anxiety-related help-seeking intentions. The results have theoretical implications for the study of masculinity and clinical implications for therapeutic approaches for men with anxiety symptoms.

Anxiety and suicidality in the college student population

Objective: This study examined symptoms of anxiety, depression and suicidality in a national sample of college students. Participants: Using national survey data from the Healthy Minds Study (HMS), a random sample from 184 U.S. campuses from fall 2016 to spring 2019 was analyzed (N = 119,875). Methods: Prevalence rates were examined with the Generalized Anxiety Disorder 7-Item scale, Patient Health Questionnaire-9 and suicidality questions. Relationships between anxiety, depression and suicidality were assessed through Spearman's correlations, the Kruskal-Wallis H test and logistic regressions. Results: Findings revealed that screening only for depression would pick up 23% of suicidal ideation, increasing to 35% when also screening for anxiety. Those with anxiety and no to minimal depression had the second highest likelihood of suicide attempt, following those with anxiety and depression. The symptom "feeling afraid something awful might happen" doubled the odds of suicidal ideation. Conclusions: College campuses may benefit from assessing particular anxiety symptoms in relation to suicide.

The relationships between anxiety and suicidal ideation and between depression and suicidal ideation among Chinese college students: A network analysis

Background

Suicide is a worldwide public health problem. Evidence from previous studies has confirmed the relationship among anxiety, depression and suicidal ideation. However, the complex psychopathological pathways between anxiety and suicidal ideation and between depression and suicidal ideation require further study.

Methods

A total of 505 college students from Shanghai during COVID-19 pandemic were investigated in an online study. Anxiety, depression and suicidal ideation of the participants were investigated. R software was used to construct the anxiety-suicidal ideation and depression-suicidal ideation networks and to evaluate the bridge expected influences.

Results

The anxiety-suicidal ideation network had 28 cross-community edges, the strongest one was A7 "Afraid something will happen"-S7 "Unable to solve personal problem"; A5 "Restlessness" and S3 "Hopelessness and suicide thoughts" had the highest bridge expected influences. The depression-suicidal ideation network had 36 cross-community edges, and the strongest one was D9 "Thoughts of death"-S5 "Unable to accomplish something important"; D9 "Thoughts of death" and S3 "Hopelessness and suicide thoughts" had the highest bridge expected influences.

Conclusion

Intricate psychopathological pathways exist between anxiety and suicidal ideation and between depression and suicidal ideation. "Restlessness", "Thoughts of death" and "Hopelessness and suicide thoughts" are considered targets for suicidal ideation interventions. The present study enriches the theory of symptoms and mental disorders and provides a reliable reference for the intervention practice of suicidal ideation.

High Levels of Anxiety, Depression, Risk of Suicide, and Implications for Treatment in Patients with Lamellar Ichthyosis

Lamellar ichthyosis (LI) is a genodermatosis that injures the structure and function of the skin, affecting the appearance and self-esteem of patients, which may seriously impair their mental health and quality of life. In the present study, we determined anxiety, depression, and suicidal risk levels in patients with LI through the Beck anxiety and depression inventories (BAI and DBI-II, respectively) and the SAD PERSONS scale (SPS). We observed that anxiety, depression, and suicidal ideation were strongly associated with the LI (Cramér's V = 0.429, 0.594, and 0.462, respectively). Furthermore, patients with LI showed a significant increase in the scores of anxiety, depression, and suicidal risk (p = 0.011, <0.001, and 0.001, respectively) compared to individuals without the disease. Additionally, the suicide risk increased even more in patients who presented comorbidity of anxiety and depression than in patients who presented only anxiety or depression (p = 0.02). Similarly, the increase in the BAI scores correlated with the score observed on the SPS. Our results indicate that patients with LI have higher levels of anxiety and depression compared to individuals without the disease, which could be associated with suicidal risk. Therefore, the collaborative involvement of skin and mental health professionals is necessary to manage patients with LI appropriately. We believe that psychiatric studies and individual evaluations must be performed in LI patients to determine a treatment that, in addition to reducing skin symptoms, focuses on reducing the levels of depression and anxiety and improving the quality of life to reduce the risk of suicide.

Longitudinal associations among dimensional symptoms of depression and anxiety and first onset suicidal ideation in adolescents

INTRODUCTION

Depression and anxiety are implicated in suicide risk, but the contributionof specific symptom dimensions within these disorders is not well understood. The present study examined longitudinal associations of transdiagnostic symptoms (General Distress[GD]) and unique symptom dimensions (Anhedonia-Apprehension [AA], Fears, and Narrow Depression [ND]) of depression and anxiety and suicidal ideation (SI).

METHODS

Data from 551 adolescents oversampled on high neuroticism were examined in a series of discrete-time survival analyses to predict first SI onset over an 8-year period.

RESULTS

Results indicate that GD, AA, and ND were independent predictors of increased likelihood of SI onset and remained significant when controlling for effects of fears. Furthermore, AA and GD remained significant when controlling for one another. ND effects reduced by 24% when adjusting for AA and 74% when adjusting for GD. Fears did not significantly predict SI onset.

CONCLUSION

Results suggest that broad levels of distress across depression and anxiety, deficits in positive affect, and elevated negative affect specific to depression increase the likelihood of suicidal thoughts. As such, attention to broader distress and a lack of pleasure, interest, and motivation-potentially more so than negative affect characterizing depression-are particularly important for addressing suicide risk in adolescents.

Reduction in avoidance mediates effects of brief behavioral therapy for pediatric anxiety and depression

Brief behavioral therapy (BBT) is an efficacious transdiagnostic intervention for pediatric anxiety and depression that targets behavioral avoidance as a key mechanism. It is unknown if change in avoidance mediates treatment effects, as theorized. Data on avoidance at baseline and Week 16 were available on 52 youth (ages 8-16 years) from a randomized controlled trial (Weersing, Jeffreys, et al., 2017) comparing BBT and assisted referral to community care (ARC). BBT had significant effects on youth-reported behavioral avoidance, and significant indirect effects on functioning and anxiety, statistically mediated through changes in youth-reported behavioral avoidance. Change in youth-reported avoidance was not a significant mediator of depression. Parent-report of avoidance was not impacted by treatment and was not a significant mediator. Overall, BBT appears to be an effective treatment for targeting behavioral avoidance, which in turn, may improve functioning and lessen anxiety.

Suicidal ideation among men during COVID-19: Examining the roles of loneliness, thwarted belongingness, and personality impairment

Suicidal ideation (SI) is a known precursor to suicide among men. While loneliness and thwarted belongingness (TB) have been identified as key factors influencing SI, no study has reported on all three constructs to investigate whether loneliness is associated with SI by way of TB. Furthermore, it is not clear whether personality impairment has a moderating role on this process. The present study examined the impact of loneliness on SI among men and whether TB mediated this relationship. Additionally, the study investigated whether personality impairment (i.e., self-functioning, interpersonal functioning) moderated the relationship between loneliness and TB. Canadian men (N = 434) completed an online survey that included self-report assessments of the study constructs. Conditional process modeling was used to test the indirect effect of loneliness on SI via the mediating effect of TB. Findings indicated a significant association between loneliness and SI that was mediated by TB. Further, impairment in self-functioning moderated the relationship between loneliness and TB, indicating that the relationship was stronger among men with greater difficulties in self-functioning. The findings are important to consider within the COVID-19 context, as they point to the need to reduce the detrimental impacts of loneliness, thereby potentially mitigating male SI.

Psychosocial factors associated with anxious depression

BACKGROUND

Anxious depression is a common subtype of major depressive disorder (MDD) associated with adverse outcomes and severely impaired social function. The aim of this study was to explore the relationships between child maltreatment, family functioning, social support, interpersonal problems, dysfunctional attitudes, and anxious depression.

METHODS

Data were collected from 809 MDD patients. The Hamilton Anxiety Scale (HAMA), Hamilton Depression Scale-17 (HAMD-17), Family Assessment Device (FAD), Childhood Trauma Questionnaire (CTQ), Social Support Rating Scale (SSRS), Interpersonal Relationship Integrative Diagnostic Scale (IRIDS), and Dysfunctional Attitudes Scale (DAS) were administered and recorded. Anxious depression was defined as an anxiety/somatization factor score ≥ 7 on the HAMD-17. Chi-squared tests, Mann-Whitney U tests, distance correlations, and structural equation models were used for data analysis.

RESULTS

Two-fifths of MDD patients had comorbid anxiety, and there were significant differences in child maltreatment, family functioning, social support, interpersonal problems, and dysfunctional attitudes between groups. Of these factors, interpersonal relationships were most related to anxiety in MDD patients, and dysfunctional attitudes mediated the relationship between interpersonal relationships and anxiety in MDD patients.

LIMITATIONS

This study used cross-sectional data with no further follow-up to assess patient outcomes. This study did not include information about pharmacological treatments. A larger sample size is needed to validate the results.

CONCLUSIONS

Psychosocial factors were significantly associated with anxious depression. Interpersonal relationships and dysfunctional attitudes have a direct effect on anxious depression, and interpersonal relationships also mediate the effects of anxious depression via dysfunctional attitudes.

Associations between anxiety, depression, and risk of suicidal behaviors in Chinese medical college students

Background

Previous studies have established a strong association between depression and suicidal behaviors, yet the relationship between anxiety and suicidal behaviors remains unclear. This study examines whether anxiety and depression are independent risk factors for suicidal behaviors in medical college students, and further, whether anxiety may increase the greater risk of suicidal behaviors (SB) in participants with depression.

Methods

This cross-sectional study was conducted among 4,882 medical students. Demographic information, anxiety, and depression data were collected using online questionnaires or through a widely used social media app named WeChat.

Results

Anxiety and depression were independent risk factors for suicidal behaviors, and levels of risk correlated positively with the severity of both anxiety and depressive symptoms. A dose-response relationship was identified between the severity of anxiety and the risk of SB, as well as the severity of depression and SB. Furthermore, anxiety increased the risk of suicidal behaviors in participants with depression, with a dose-response relationship between the severity of anxiety symptoms and the risk of SB.

Conclusion

The findings highlight the importance of screening for anxiety and depressive symptoms in medical college students, as well as reducing anxiety in addition to depressive symptoms in treatment. This study provides valuable data as a reference for clinicians for suicide risk assessments.

Self-compassion and social anxiety: The mediating effect of emotion regulation strategies and the influence of depressed mood

OBJECTIVES

Self-compassion constitutes a positive way of relating towards the self that enables emotional regulation and reduces emotional distress. This research first explored differences among a sample of persons with social anxiety disorder (SAD) and groups of high socially anxious (HSA) and low socially anxious (LSA) students on self-compassion, emotion regulation, and social anxiety. We then investigated emotional regulation as a mediator of the prediction of social anxiety by self-compassion and the influence of depressed mood on those relationships.

DESIGN

Study 1 compared a SAD group to matched groups of HSA and LSA students. Study 2 utilized the total sample (n = 330 students and n = 33 SAD) to test mediation. Self-compassion and emotion regulation were predictors of social anxiety and depression a covariate.

RESULTS

In Study 1, the SAD group did not differ from the HSA group on most aspects of self-compassion and emotional regulation but was higher on depression. Both were lower on most measures and higher on depression than the LSA group. In Study 2, higher self-compassion predicted lower social interaction anxiety, and emotional regulation strategies mediated this effect, regardless of depression. However, for social performance anxiety, controlling for depression removed mediation. Refraining from uncompassionate responses was directly connected to social anxiety, whereas compassionate responses influenced social anxiety via emotional regulation.

CONCLUSIONS

Results affirm the ameliorative role of self-compassion on social anxiety and emotion regulation strategies as mechanisms of that influence. However, self-compassion's influence was affected by depression and type of social anxiety. Also, refraining from uncompassionate self-responding appears to be of prime importance in predicting social anxiety, whereas compassionate self-responding influences social anxiety via emotion regulation.

The Relationship Among Anxiety Sensitivity, Psychache, and Suicidality in Patients With Generalized Anxiety Disorder

Although generalized anxiety disorder (GAD) is associated with suicide, not all dimensions of this relationship have been addressed. This study aimed to investigate the relationship between psychache and anxiety sensitivity with suicidality in patients with GAD. We included 80 patients with GAD (17 of whom had previous suicide attempts). The Hamilton Anxiety Rating Scale (HAM-A), Hamilton Depression Scale (HAM-D), Beck Scale for Suicidal Ideation (BSIS), Psychache Scale (PS), and Anxiety Sensitivity Index-3 (ASI) were applied to the participants. The patients with previous suicide attempts had significantly higher scores on ASI total, ASI-physical and cognitive subdimensions, HAM-A total and psychic subscale, PS, and BSIS than those without ( p &lt; 0.05 for each). Mediation analyses revealed that psychache was a full mediator in the relationship between ASI-cognitive subdimension and suicidal ideation. Therapeutic interventions for anxiety sensitivity and psychache in patients with GAD will help reduce the risk of suicide.

Digital phenotyping of generalized anxiety disorder: using artificial intelligence to accurately predict symptom severity using wearable sensors in daily life

BACKGROUND

Generalized anxiety disorder (GAD) is a highly prevalent condition. Monitoring GAD symptoms requires substantial time, effort, and cost. The development of digital phenotypes of GAD may enable new scalable, timely, and inexpensive assessments of GAD symptoms.

METHOD

The current study used passive movement data collected within a large national cohort (N = 264) to assess GAD symptom severity.

RESULTS

Using one week of movement data, machine learning models accurately predicted GAD symptoms across a continuum (r = 0.511) and accurately detected those individuals with elevated GAD symptoms (AUC = 0.892, 70.0% Sensitivity, 95.5% Specificity, Brier Score = 0.092). Those with a risk score at the 90th percentile or above had 21 times the odds of having elevated GAD symptoms compared to those with lower risk scores. The risk score was most strongly associated with irritability, worry controllability, and restlessness (individual rs > 0.5). The risk scores for GAD were also discriminant of major depressive disorder symptom severity (r = 0.190).

LIMITATIONS

The current study examined the detection of GAD symptom severity rather than the prediction of GAD symptom severity across time. Furthermore, the instant sample of data did not include nighttime actigraphy, as participants were not asked to wear the actigraphs at night.

CONCLUSIONS

These results suggest that artificial intelligence can effectively utilize wearable movement data collected in daily life to accurately infer risk of GAD symptoms.

Latent class growth modeling of depression and anxiety in older adults: an 8-year follow-up of a population-based study

BACKGROUND

Depression and anxiety are common mental health conditions in the older adult population. Understanding the trajectories of these will help implement treatments and interventions.

AIMS

This study aims to identify depression and anxiety trajectories in older adults, evaluate the interrelationship of these conditions, and recognize trajectory-predicting characteristics.

METHODS

Group-based dual trajectory modeling (GBDTM) was applied to the data of 3983 individuals, aged 65 years or older who participated in the Korean Health Panel Study between 2008 and 2015. Logistic regression was used to identify the association between characteristics and trajectory groups.

RESULTS

Four trajectory groups from GBDTM were identified within both depression and anxiety outcomes. Depression outcome fell into "low-flat (87.0%)", "low-to-middle (8.8%)", "low-to-high (1.3%)" and "high-stable (2.8%)" trajectory groups. Anxiety outcome fell into "low-flat (92.5%)", "low-to-middle (4.7%)", "high-to-low (2.2%)" and "high-curve (0.6%)" trajectory groups. Interrelationships between depression and anxiety were identified. Members of the high-stable depression group were more likely to have "high-to-low" or "high-curved" anxiety trajectories. Female sex, the presence of more than three chronic diseases, and being engaged in income-generating activity were significant predictors for depression and anxiety.

CONCLUSIONS

Dual trajectory analysis of depression and anxiety in older adults shows that when one condition is present, the probability of the other is increased. Sex, having more than three chronic diseases, and not being involved in income-generating activity might increase risks for both depression and anxiety. Health policy decision-makers may use our findings to develop strategies for preventing both depression and anxiety in older adults.

Efficacy of Agomelatine 25-50 mg for the Treatment of Anxious Symptoms and Functional Impairment in Generalized Anxiety Disorder: A Meta-Analysis of Three Placebo-Controlled Studies

Introduction

The purpose of this study is to investigate the effects of agomelatine on anxious symptoms and functional impairment in a pooled dataset from randomized placebo-controlled trials for generalized anxiety disorder (GAD).

Methods

Data from three randomized, placebo-controlled trials that evaluated the efficacy of agomelatine 25–50 mg were pooled. The short-term (12 weeks) efficacy of agomelatine was assessed in regards to (1) anxious symptoms using the Hamilton Anxiety Scale (HAM-A), and (2) functional impairment using the Sheehan Disability Scale (SDS). Meta-analysis using a random effect model was used to assess differences between groups. Remission and response rates for the HAM-A and SDS were calculated, and analyses were repeated in participants with more severe anxiety symptoms.

Results

In total, 669 patients (340 on agomelatine; 329 on placebo) were included in the analyses. Compared to placebo, the agomelatine group had a significant reduction in HAM-A total score at week 12 (between group difference: 6.30 ± 2.51, p = 0.012). Significant effects were also found for symptom response on the HAM-A (67.1% of patients on agomelatine vs. 32.5% on placebo) and symptom remission (38.8% of patients on agomelatine vs. 17.3% on placebo). Compared to placebo, there was a significant difference in favour of the agomelatine group at week 12 on the SDS total score (5.11 ± 1.81, p = 0.005). Significant effects were also found for functional response on the SDS (79.1% of patients on agomelatine vs. 43.2% of placebo) and functional remission (55.2% of patients on agomelatine vs. 25.4% on placebo). All findings for anxious symptoms and functional impairment were confirmed in the subset of more severely anxious patients. Agomelatine was well tolerated by patients.

Conclusion

This meta-analysis confirms that agomelatine reduces anxiety symptoms and improves the global functioning of GAD patients.

Latent class analysis of bipolar disorder symptoms and suicidal ideation and behaviors

Individuals with bipolar disorder are at increased risk of dying by suicide compared to healthy controls and those with unipolar depression. Previous studies show that depressive symptoms and mixed episodes of mania and depression are related to suicide. However, most of these studies adopt a variable-centered approach to understanding how specific symptoms relate to suicidal ideation, without addressing how these symptoms and symptom profiles relate to suicidal behaviors.

OBJECTIVES

Using latent class analysis, this study adopts a person-centered approach to examine whether subtypes of patients with bipolar disorder differ in their levels of suicidal ideation and behaviors.

METHODS

A total of 150 patients from a behavioral health outpatient clinic were recruited. Latent classes were generated based on self reports of their depressive and manic symptoms.

RESULTS

Five classes of patients with bipolar disorder were identified, namely, a minimal symptom, mania, moderately depressed, severely depressed, and mixed depression-mania subtypes. Those in the severely depressed and mixed depression-mania groups reported significantly higher levels of suicidal ideation and behaviors compared to the other groups.

CONCLUSIONS

Our findings provide further support for the strong relationship between depressive symptoms and suicidality. These findings are significant as they shed light on the different suicide risk profiles among a heterogenous group of patients with bipolar disorder.

Suicidal ideation among Lebanese adults: scale validation and correlates

BACKGROUND

According to the World Health Organization (WHO) figures in 2015, the number of people attempting suicide worldwide per year exceeds 800,000 individuals. The majority of completed suicides (78%) occur in low- and middle-income countries. Therefore, this study aimed to validate the suicidal ideation subscale of the Columbia-Suicide Severity Rating Scale and evaluate risk factors (emotional intelligence, alexithymia, anxiety, depression, and stress) related to suicidal ideation among the Lebanese adult population.

METHODS

A structured cross-sectional survey was carried out between November 2017 and March 2018, enrolling a proportionate random sample of 789 community-dwelling participants from all the Lebanese regions. A correlation analysis between the C-SSRS and anxiety and depression assessed the convergent validity of the scale. An exploratory and a confirmatory factor analysis validated its construct. Cronbach's alpha was used to assess internal consistency reliability. Multiple linear regression was performed using the suicidal ideation score as the dependent variable. All variables were included in the multivariable model.

RESULTS

The C-SSRS scale converged over a solution of one factor; the proportion of explained variance was 0.797. The Cronbach's alpha value was good (0.797). The convergent validity was tested with depression and anxiety scales. The results showed a moderate positive correlation between the suicide ideation score and depression (rho = 0.507, p < 0.001) and anxiety (rho = 0.402, p < 0.001). The multivariable analysis showed that higher depression (Unstandardized Beta, B = 0.035, p < 0.001), higher anxiety (B = 0.015, p = 0.008), and higher alcohol dependence (B = 0.024, p < 0.001) were significantly linked to higher suicidal ideation score. However, higher self-esteem (B = -0.041, p = 0.006) was significantly associated with lower suicidal ideation scores.

CONCLUSION

Our findings suggest that the Arabic version of the C-SSRS subscale could serve as an appropriate assessment tool for suicidal ideation. This paper also gave insights into factors correlated with higher suicidal ideation scores, such as depression, anxiety, and alcohol dependence. Further studies are necessary to confirm our findings and implement suicide prevention programs.

Interaction between anxiety and depression on suicidal ideation, quality of life, and work productivity impairment: Results from a representative sample of the Lebanese population

PURPOSE

To assess the association between the interaction of anxiety and depression on the suicidal ideation, quality of life (QOL), and work productivity/impairment in Lebanon.

DESIGN

Cross-sectional.

METHODS

1487 participants were enrolled between November 2017 and March 2018.

RESULTS

The interaction of anxiety and depression (β = .101), higher depression alone (β = .021), higher anxiety traits (STAI-B) (β = .007) were associated with higher suicidal ideation. Higher depression (β = 1.177), having more anxiety traits (STAI-B) (β = .485) and higher anxiety (STAI-A) (β = .298) were associated with higher activity impairment. Higher depression, higher anxiety traits and state, were associated with lower mental and physical QOL.

PRACTICE IMPLICATIONS

Screening for anxiety and depression can help clinicians improve patients' QOL and work productivity and decrease the suicidal ideation risk.

Predictors of Passive and Active Suicidal Ideation and Suicide Attempt Among Older People: A Study in Tertiary Care Settings in Thailand

PURPOSE

This study compared predictors of passive suicidal ideation (SI), active SI, and suicide attempt (SA) among elderly Thai patients in tertiary care settings.

PATIENTS AND METHODS

Psychiatric diagnoses and suicidality of 803 older people were assessed using the Mini-International Neuropsychiatric Interview and the Structured Clinical Interview for DSM-IV-TR. All participants completed the Montreal Cognitive Assessment, multidimensional scale of perceived social support (MSPSS), 15-item Thai geriatric depression scale (TGDS-15), 10-item perceived social scale and the Core Symptoms Index. The chi-square test, t-test and ANOVA were used for bivariate analysis of predictors of specific suicidality types. Multiple logistic regression was used to determine the predictors for each type of suicidality.

RESULTS

The patients' mean age was 69.24 ± 6.90 years, and the majority were female (69.74%). Passive SI, active SI and SA were found among 20.42%, 3.74% and 2.37%, respectively, of the patients. Major depressive disorder (MDD) was a predictor of both passive and active SI (OR = 2.06 and 3.74, respectively). Other predictors of passive SI included hypomania (OR = 8.27) and positive score on the TGDS-15 (OR = 1.29). Predictors of active SI included agoraphobia (OR = 6.84) and hypomania (OR = 7.10). Predictors of SA included a family history of alcohol dependence (OR = 14.16), a history of depression (OR = 4.78) and agoraphobia (OR = 19.89). Surprisingly, hypertension and self-reported anxiety symptoms were protective factors for passive SI (OR = 0.51 and 0.85, respectively). Likewise, MSPSS was a protective factor for SA (OR = 0.90).

CONCLUSION

Predictors of each type of suicidality differed. MDD was the main predictor for SI; however, agoraphobia and poor perceived social support were more pronounced among individuals with SA. Further investigation, especially in longitudinal fashion, should be warranted.

What is the Role of Internalizing and Externalizing Symptoms in Adolescent Suicide Behaviors?

Suicide is the second leading cause of death in adolescents and young adults aged 15 to 29 years. Specifically, the presence of internalizing and externalizing symptomatology is related to increased risk for suicide at these ages. Few studies have analyzed the relations between these symptoms and their role as mediators in predicting suicide behavior. This study aimed to examine the relation between internalizing and externalizing symptomatology and suicide behaviors through a longitudinal study. The sample consisted of 238 adolescents aged 12 to 18 years. The data were analyzed via the PROCESS Statistical Package. The main results showed that previous depression symptoms had a significant indirect effect, through previous suicide behaviors and current depression symptoms, on current suicide behaviors, accounting for 61% of the total variance explained. Additionally, being a girl increased this risk. Therefore, the implementation of early identification and intervention programs to address youth symptoms of depression and suicidal behaviors could significantly reduce the risk for future suicidal behaviors in adolescence.

Perceived Discrimination and Suicide Ideation: Moderating Roles of Anxiety Symptoms and Ethnic Identity among Asian American, African American, and Hispanic Emerging Adults

Suicide is a leading cause of death for vulnerable ethnic minority emerging adults in the United States (Web-based injury statistics query and reporting system [WISQARS], 2015). Perceived discrimination (Journal of Youth and Adolescence, 40, 2011, 1465) and anxiety symptoms (Asian American Journal of Psychology, 1, 2010, 18) are two predictors that are theoretically and conceptually related, but have yet to be examined in a simultaneous model for suicide ideation. Existing theory and research suggest that these variables activate similar pathways (American Behavioral Scientist, 51, 2007, 551). This study sought to address this gap in the literature by examining the simultaneous relationship between perceived discrimination and anxiety symptoms as predictors of suicide ideation. The moderating effect of anxiety symptoms on the relationship between perceived discrimination and suicide ideation was examined in a multiethnic sample of emerging adults. Results indicated that anxiety symptoms moderated the perceived discrimination-suicide ideation relationship for Hispanic emerging adults, but not for their Asian American and African American counterparts. Furthermore, ethnic identity has been shown to mitigate suicide risk in the face of other stressors (Cultural Diversity and Ethnic Minority Psychology, 14, 2008, 75). Ethnic identity emerged as a protective factor for Hispanic emerging adults by further interacting with perceived discrimination and anxiety symptoms to negatively predict suicide ideation. The implications of these findings 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.

Symptoms of social anxiety disorder and major depressive disorder: A network perspective

BACKGROUND

We used network analyses to examine symptoms that may play a role in the co-occurrence of social anxiety disorder (SAD) and major depressive disorder (MDD). Whereas latent variable models examine relations among latent constructs, network analyses have the advantage of characterizing direct relations among the symptoms themselves.

METHOD

We conducted network modeling on symptoms of social anxiety and depression in a clinical sample of 130 women who met criteria for SAD, MDD, both disorders, or had no lifetime history of mental illness.

RESULTS

In the resulting network, the core symptoms of social fear and depressed mood appeared at opposite ends of the network and were weakly related; so-called "bridges" between these symptoms appeared to occur via intervening variables. In particular, the worthless variable appeared to play a central role in the network.

LIMITATIONS

Because our data were cross-sectional, we are unable to draw conclusions about the direction of these effects or whether these variables are related to each other prospectively.

CONCLUSIONS

Continued testing of these pathways using longitudinal data will help facilitate the development of more effective clinical interventions for these disorders.

12-week double-blind randomized multicenter study of efficacy and safety of agomelatine (25-50 mg/day) versus escitalopram (10-20 mg/day) in out-patients with severe generalized anxiety disorder

Treatment of severely symptomatic patients with generalized anxiety disorder (GAD) raises particular concerns for clinicians. This 12-week double-blind study evaluated the efficacy of agomelatine (25-50 mg/day) in the treatment of patients with severe GAD, using escitalopram (10-20 mg) as active comparator. The primary outcome measure was the change from baseline of the total score on the Hamilton Anxiety scale (HAM-A) at week 12. Secondary outcome measures included rate of response to treatment (at least 50% score reduction from baseline) in the HAM-A psychic and somatic anxiety sub-scores, Clinical Global Impression severity and change scores, the Toronto Hospital Alertness Test, the Snaith-Hamilton Pleasure Scale, and the Leeds Sleep Evaluation Questionnaire Scores. Sixty one clinical centers (Australia, Canada, Czech Republic, Finland, Germany, Hungary, Poland, Russia, Slovakia) participated from April 2013 to February 2015. Patient characteristics and demographic data were comparable between treatment groups. Both treatments were associated with a clinically significant decrease in HAM-A total score at week 12; the non-inferiority of agomelatine versus escitalopram was not demonstrated (E(SE) = -0.91(0.69), 95%CI = [-2.26, 0.44], p = 0.195). At week 12, the response rate was 60.9% in the agomelatine group, and 64.8% in the escitalopram group. In both treatment arms, HAM-A psychic and somatic anxiety scores decreased, alertness and sleep parameters improved, and ability to experience pleasure increased. In these secondary outcome measures, there were no significant differences between the treatment groups. Agomelatine was well-tolerated, with a lower incidence of adverse events than escitalopram. Agomelatine and escitalopram are efficacious in treating GAD patients with severe symptoms.

The Anxiety Depression Distress Inventory-27 (ADDI-27): New Evidence of Factor Structure, Item-Level Measurement Invariance, and Validity

Three studies examining the factor structure and psychometric properties of the Anxiety Depression Distress Inventory-27 (ADDI-27) extended the initial instrument development studies for this recently introduced inventory. The ADDI-27 is an empirically derived short form of the Mood and Anxiety Questionaire-90 (MASQ-90) comprising three scales: Positive Affect, Somatic Anxiety, and General Distress. The main objectives of Study 1 (N = 700) were to examine the factor structure of the ADDI-27 and its measurement invariance across gender at the item level. The objective of Study 2 (N = 538) was to examine evidence for the convergent and discriminant validity of scores on the ADDI-27. The objective of Study 3 (N = 240) was to assess further evidence for the nomological network and convergent and discriminant validity of the ADDI-27 scores. Results of exploratory structural equation modeling yielded strong support for a 3-factor model, with approximate fit indexes meeting or exceeding the conventional cutoffs. With p ≤ .001 as the criterion for detecting noninvariance, results of measurement invariance analysis suggested that all of the ADDI-27 items were invariant across gender. Results of multivariate validity analyses across 2 studies provided support for the convergent and discriminant validity of scores on the ADDI-27 scales.

Current suicidal ideation in treatment-seeking individuals in the United Kingdom with gambling problems

BACKGROUND

Studies show higher lifetime prevalence of suicidality in individuals with pathological gambling. However, less is known about the relationship between pathological gambling and current suicidal ideation.

OBJECTIVES

We investigated socio-demographic, clinical and gambling-related variables associated with suicidality in treatment-seeking individuals.

METHODS

Bivariate analyses and logistic regression models were generated on data from 903 individuals to identify measures associated with aspects of suicidality.

RESULTS

Forty-six percent of patients reported current suicidal ideation. People with current suicidal thoughts were more likely to report greater problem-gambling severity (p<0.001), depression (p<0.001) and anxiety (p<0.001) compared to those without suicidality. Logistic regression models suggested that past suicidal ideation (p<0.001) and higher anxiety (p<0.05) may be predictive factors of current suicidality.

CONCLUSIONS

Our findings suggest that the severity of anxiety disorder, along with a lifetime history of suicidal ideation, may help to identify treatment-seeking individuals with pathological gambling with a higher risk of suicidality, highlighting the importance of assessing suicidal ideation in clinical settings.

Cyr K, Nelson C, Sareen J, Elhai J, Zamorski M. Insomnia, psychiatric disorders and suicidal ideation in a National Representative Sample of active Canadian Forces members

BACKGROUND

Past research on the association between insomnia and suicidal ideation (SI) has produced mixed findings. The current study explored the relationship between insomnia, SI, and past-year mental health status among a large Canadian Forces (CF) sample.

METHOD

Data was obtained from the 2013 Canadian Forces Mental Health Survey (CFMHS), and included a large representative sample of Canadian Regular Forces personnel (N = 6700). A series of univariate logistic regressions were conducted to test individual associations between past-year mental health status, insomnia, and potential confounds and SI. Mental health status included three groups: 0, 1, or two or more probable diagnoses of posttraumatic stress disorder (PTSD), major depressive disorder (MDD), generalized anxiety disorder (GAD), panic disorder (PD) and alcohol abuse/dependence. Stepwise multivariate logistic regression was used to assess the relationship between insomnia and SI with mental health status as a moderator.

RESULTS

40.8% of respondents reported experiencing insomnia. Both insomnia and number of mental health conditions incrementally increased the risk of SI. However, past-year mental health status was a significant moderator of this relationship, such that for CF personnel with either no (AOR = 1.61, 1.37-1.89) or only one past-year mental health condition (AOR = 1.39, 1.12-1.73), an incremental increase in insomnia was associated with an increased likelihood of SI. However, in personnel with two or more past-year mental health disorders, insomnia was no longer significantly associated with SI (AOR = 1.04, 0.81-1.33).

CONCLUSIONS

Insomnia significantly increased the odds of SI, but only among individuals with no or one mental health condition. Findings highlight the importance of assessing insomnia among CF members in order to further suicide prevention efforts.

The relationship between anxiety, depression and risk behaviors in adolescents

Aim Adolescence is a developmental period often associated with high-risk behaviors. While some risk-taking behavior is considered normative in adolescents, research has indicated an association between risky behaviors and mental ill-health. The current research aimed to examine the relationship between anxiety and depression with the occurrence of high-risk behaviors in adolescents and also determine the predictive factors of these main variables. Methods A descriptive, cross-sectional, correlational design was used to collect data from 399 adolescents between the ages of 14 and 19 residing in Qazvin, Iran using the Revised Child Anxiety and Depression Scale (RCADS) and the Iranian Adolescents Risk-taking Scale (IARS) between the period of October and November 2015. Data analysis included descriptive and inferential statistics powered by SPSS (v. 23). Results Mean scores for anxiety, depression and risky behaviors were 37.70 ± 21.11 and 80.76 ± 31.30, respectively. Participants' frequency of suicidal thoughts (β = 0.126, p < 0.05) positively predicted anxiety and depression, while age (β = -0.126, p < 0.01) and self-confidence (β = -0.307, p < 0.001) negatively predicted anxiety and depression. Moreover, having friends that smoke (β = 0.366, p < 0.001), suicidal thoughts (β = 0.127, p < 0.01), and the strength of suicidal thoughts (β = 0.100, p < 0.05) were positive predictors of occurrence of risky behaviors. Furthermore, religious belief (β = -0.204, p < 0.001) negatively predicted occurrence of risky behaviors in Iranian adolescents. Male respondents were more likely to have higher level of occurrence of risky behaviors than females (β = -0.193, p < 0.001). Conclusion Findings of the present study suggest that anxiety and depression positively and significantly predict the occurrence of risky behaviors in addition to having friends that smoke, suicidal thoughts, and strong suicidal thinking. The implications of these findings have relevance for screening, prevention, and treatment interventions targeting mental health in adolescents.

Use of Electronic Nicotine Delivery Systems among Adults with Mental Health Conditions, 2015

Adults with mental health conditions (MHC) are especially likely to smoke and experience tobacco-related health disparities. Individuals with MHC may also use electronic nicotine delivery devices (ENDS) at disproportionately high rates. However, there is a relative dearth of knowledge regarding ENDS use among individuals with MHC. In a large representative sample of U.S. adults (n = 6051), associations between self-reported MHC diagnoses and ENDS use and susceptibility were examined, stratified by smoking status. Participants with MHC were approximately 1.5 times more likely to have used ENDS in their lifetime and almost twice as likely to currently use ENDS as those without MHC. MHC status was most strongly linked to higher ENDS use among former smokers, and former smokers with MHC were more likely to report using ENDS during past smoking quit attempts than those without MHC. Among participants who had not tried ENDS, former smokers with MHC were especially susceptible to future ENDS use. The potential advantage of ENDS for cessation purposes should be balanced with the risk of attracting former smokers with MHC to ENDS.

When social anxiety and depression go together: A population study of comorbidity and associated consequences

BACKGROUND

Despite several studies suggesting higher depression severity and dysfunction occurring in individuals with major depressive disorder (MDD) comorbid with social anxiety disorder (SAD), a clear understanding of the specific risks associated with this comorbidity is lacking. In this study we compared the disease characteristics and level of disability of individuals with MDD-SAD with other comorbidities between depression and anxiety.

METHODS

Data from the Collaborative Psychiatric Epidemiology Surveys (CPES) (N=20,013) were used. Individuals were divided in four groups comparing MDD-SAD with MDD alone, as well as other comorbidities between MDD and one anxiety (MDD-1ANX) or more than two anxiety disorders (MDD≥2ANX), with respect to several clinical, demographic, and functional characteristics.

RESULTS

MDD-SAD comorbidity in the general population occurred in younger people, particularly men, and seemed to have an earlier onset of MDD. Occupational and social dysfunction was similar between individuals with MDD-SAD and those with MDD-1ANX. However, individuals with MDD≥2ANX had significantly higher severity as measured by suicidality as well as substance abuse and social and occupational dysfunction. SAD was the most prevalent comorbid anxiety in this group.

LIMITATIONS

The findings of this study were derived from the cross-sectional data.

CONCLUSION

Our results suggest that the particular risks associated with MDD-SAD are the early onset and likelihood of additional anxiety, leading to higher severity and disability levels. Clinicians should increase the screening and treatment of SAD and other anxiety disorders in individuals with MDD given the higher associated health risk and functional impairment.

Suicidal ideation among rural immigrant daughters-in-law with multi-roles as females, farmers and immigrants in China

Suicide is a major public health issue in China, and suicidal ideation is an important step in the suicidal process. The purpose of this study was to understand the prevalence and correlates of suicidal ideation among rural immigrant daughters-in-law with multi-role of female, farmer and immigrant in China. A total of 939 participants including 474 local daughters-in-law and 465 immigrant daughters-in-law were surveyed using the self-rating questionnaire. Demographic characteristics, depression, anxiety, impulsivity and suicidal ideation were assessed. Results indicated that the lifetime prevalence of suicidal ideation among rural immigrant daughters-in-law was 9.68%. Physical disability, domestic violence and negative events demonstrated statistical significance by suicidal ideation (p < .05), and participants with suicidal ideation had higher scores of depression, anxiety and impulsiveness in the univariate analysis. Multivariate logistic regression showed that physical disability (OR = 7.43, 95%CI: 2.84-19.46), domestic violence (OR = 2.65, 95%CI: 1.02-6.88), depression (OR = 1.07, 95%CI: 1.01-1.12), impulsiveness (OR = 1.04, 95%CI: 1.01-1.08) and motor impulsiveness (OR = 1.07, 95%CI: 1.01-1.14) were significantly associated with suicidal ideation. Suicidal ideation is an issue that can't be ignored among rural immigrant daughters-in-law. And the findings should be considered for the intervention of the suicide among the rural immigrant daughters-in-law.

Naltrexone treatment reverses astrocyte atrophy and immune dysfunction in self-harming macaques

The role of glia in the development and treatment of behavioral abnormalities is understudied. Recent reports have observed glial activation in several disorders, including depression, autism spectrum disorders and self-injurious behaviors (SIB). In the current study, we examined SIB in the physiologically and anatomically relevant nonhuman primate (NHP) model. At the Tulane National Primate Research Center (TNPRC), approximately 5% of singly housed macaques develop symptoms of SIB. We have previously demonstrated that naltrexone hydrochloride can be effective in reducing SIB. We have also demonstrated that the astrocytes of animals with SIB are distinctly atrophic and display heightened innate immune activation compared with control animals. We have added a third group of animals (five macaques identified with SIB and treated with oral naltrexone at a dose of 3.2mg/kg) to the previous cohort (six macaques with a history of SIB but not treated, and nine animals with no history of SIB) for this study. Gray and white matter astrocytes from frontal cortical tissue were examined following necropsy. Innate immune activation of astrocytes, which was increased in SIB animals, was markedly decreased in animals receiving naltrexone, as was atrophy of both grey and white matter astrocytes. This was concomitant with improved behavioral correlates. Preventing astrocyte activation in select areas of the brain to reduce injurious behavior is an innovative concept with implications for mental health studies. Differences in multiple areas of primate brain would help determine how self-injurious behavior develops. These studies suggest a stronger role for astrocytes in the cellular events associated with self-injurious behaviors.

Disorder-specific versus transdiagnostic and clinician-guided versus self-guided treatment for major depressive disorder and comorbid anxiety disorders: A randomized controlled trial

Disorder-specific cognitive behavior therapy (DS-CBT) is effective at treating major depressive disorder (MDD) while transdiagnostic CBT (TD-CBT) addresses both principal and comorbid disorders by targeting underlying and common symptoms. The relative benefits of these two models of therapy have not been determined. Participants with MDD (n=290) were randomly allocated to receive an internet delivered TD-CBT or DS-CBT intervention delivered in either clinician-guided (CG-CBT) or self-guided (SG-CBT) formats. Large reductions in symptoms of MDD (Cohen's d≥1.44; avg. reduction≥45%) and moderate-to-large reductions in symptoms of comorbid generalised anxiety disorder (Cohen's d≥1.08; avg. reduction≥43%), social anxiety disorder (Cohen's d≥0.65; avg. reduction≥29%) and panic disorder (Cohen's d≥0.45; avg. reduction≥31%) were found. No marked or consistent differences were observed across the four conditions, highlighting the efficacy of different forms of CBT at treating MDD and comorbid disorders.

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.

Suicidality in obsessive compulsive disorder (OCD): a systematic review and meta-analysis

Although a growing number of studies have examined the frequency of suicidal thoughts and behaviors in individuals with obsessive compulsive disorder (OCD), there is controversy about the frequency and burden of suicidality in OCD. This is the first systematic review aimed at examining the association between suicidality and OCD and at providing evidence about psychological mechanisms that may underlie suicidality in those with OCD. Five electronic bibliographic databases were searched up to April 2014: Medline, PsycINFO, Embase, Web of Science and CINAHL. Meta-analysis using random effects models was conducted. Forty-eight studies were included in the systematic review. The pooled effect size across 30 independent comparisons revealed a moderate to high, significant association between suicidality and OCD (Hedges' g=0.66, 95% confidence interval 0.49-0.82) which persisted across different types of suicidality including suicidal ideation and suicide attempts. Comorbid Axis I disorders, increased severity of comorbid depressive and anxiety symptoms, increased severity of obsessions, feelings of hopelessness and past history of suicide attempts were associated with worsening levels of suicidality in OCD. There was no indication for publication bias but the methodological quality of the studies was low. The theoretical, research and clinical implications of these findings are emphasized.

Factors associated with suicidal ideations and suicidal attempts in patients with obsessive compulsive disorder

Aim of this study was to evaluate the prevalence of suicidal ideations (SI) and to study the risk factors for SI and suicide attempt in patients with OCD. One hundred and thirty patients with OCD were assessed on Yale-Brown Obsessive–Compulsive Scale and Symptom Checklist, Beck Depression Inventory, Beck Hopelessness Scale, Beck Anxiety Inventory, State-Trait Anxiety Inventory, Buss–Durkee Hostility Inventory, Barratt Impulsiveness Scale, Family Interview for Genetic Studies, Brown Assessment of Beliefs Scale and DSM-IV insight criteria for OCD. Of the 130 patients, 60 (46.1%) had current SI and 81 (62.3%) patients had life time SI. Of the 60 patients with current SI, 30 had current depression as assessed on SCID-CV. More than half (48 out of 81; 59.25%) of the patients with lifetime SI had lifetime comorbid depression. Ten patients had history of lifetime suicide attempts. Current SI in patients without current depression were associated with female gender, presence of comorbid psychiatric illness, contamination obsessions and cleaning/washing compulsions. To conclude this study suggests that SI are highly prevalent in patients with OCD and although depression may be a contributory factor for suicidal ideations in patients with OCD, but it is not the sole risk factor for suicidal ideations.

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.

Sleep disturbances and suicidal ideation in a sample of treatment-seeking Canadian Forces members and veterans

This study examines the association between suicidal ideation and sleep disturbances in a sample of treatment-seeking Canadian Forces members and veterans, after controlling for probable posttraumatic stress disorder (PTSD), major depressive disorder (MDD), generalised anxiety disorder (GAD), and alcohol use disorder (AUD). Subjects included members and veterans of Canadian Forces seeking treatment at a hospital-based Operational Stress Injury Clinic (n=404). Sleep disturbances and nightmares were measured using individual items on the PTSD Checklist - Military Version (PCL - M), while the suicidality item of the Patient Health Questionnaire (PHQ-9) was used as a stand-alone item to assess presence or absence of suicidal ideation. Regression analyses were used to determine the respective impact of (1) insomnia and (2) nightmares on suicidal ideation, while controlling for presence of probable PTSD, MDD, GAD, and AUD. We found that 86.9% of patients reported having problems falling or staying asleep and 67.9% of patients reported being bothered by nightmares related to military-specific traumatic events. Neither sleep disturbances nor nightmares significantly predicted suicidal ideation; instead, probable MDD emerged as the most significant predictor. The clinical implications of these findings and their potential impact on treatment guidelines are discussed.

Neural response to reward anticipation in those with depression with and without panic disorder

BACKGROUND

One of the hallmark features of major depressive disorder (MDD) is reduced reward anticipation. There have been mixed findings in the literature as to whether reward anticipation deficits in MDD are related to diminished mesolimbic activation and/or enhanced dorsal anterior cingulate activation (dACC). One of the reasons for these mixed findings is that these studies have typically not addressed the role of comorbid anxiety, a class of disorders which frequently co-occur with depression and have a common neurobiology.

METHODS

The aim of the current study was to examine group differences in neural responses to reward anticipation in 40 adults with either: (1) current MDD with no lifetime diagnosis of an anxiety disorder (MDD-only), (2) current MDD with comorbid panic disorder (MDD-PD), or (3) no lifetime diagnosis of psychopathology. All participants completed a passive slot machine task during a functional magnetic resonance imaging (fMRI) scan.

RESULTS

Analyses indicated that there were no group differences in activation of mesolimbic reward regions; however, the MDD-only group exhibited greater dACC activation during the anticipation of rewards compared with the healthy controls and the comorbid MDD-PD group (who did not differ from each other).

LIMITATIONS

The sample size was small which limits generalizability.

CONCLUSIONS

These findings provide preliminary support for the role of hyperactive dACC functioning in reduced reward anticipation in MDD. They also indicate that comorbid anxiety may alter the association between MDD and neural responding to reward anticipation.

Association between psychopathology and suicidal behavior in schizophrenia. A cross-sectional study of 509 participants

BACKGROUND

Suicide in schizophrenia is a serious problem--ideation rates go up to 40%, and approximately one half of patients attempt suicide at least once. The distinction between attempters and ideators is vital in everyday clinical practice.

AIM

To explore the association between psychopathology and suicidal behavior in a comparative study of three groups of patients with schizophrenia: suicide ideators, suicide attempters, and subjects without suicide ideation and behavior.

METHOD

The study included 509 patients: suicide attempters (n = 159), ideators (n = 180), and a comparative group (n = 170). The clinical assessment consisted of a structured psychiatric interview and an evaluation of sociodemographics, suicidality (SIBQ), psychopathology (PANSS), and depression (CDSS).

RESULTS

Suicide attempters were more depressed than ideators, and both groups had higher CDSS scores than the comparative group. The overall contribution of positive, negative, and general PANSS symptoms was not statistically significant enough to differentiate ideators from attempters. A principal component analysis of the PANSS items revealed five components: disinhibition, withdrawal, anxiety and guilt, reality distortion, and disorganization. Two logistic regression analyses showed that suicide ideation or attempt was significantly related to depression, anxiety, guilt, gender, age, and number of previous hospitalizations. Compared to suicide ideators, attempters were more depressed, had a higher number of previous hospitalizations, and lower education.

CONCLUSION

The results indicate that clinicians should look for depression, anxiety, and guilt feelings, while positive and negative symptoms seem to be less relevant for suicide assessment in schizophrenia.

Panic symptom clusters differentially predict suicide ideation and attempt

Increasingly strong evidence links anxiety disorders in general and panic attacks in particular to suicidality. The underlying causes and specifics of this relation, however, remain unclear. The present article sought to begin addressing this question by clarifying the association between panic symptoms and suicidality. Data were sampled from the NESARC epidemiological data set from the US and analyzed as four independently, randomly selected subsets of 1000 individuals using structural equation modeling analyses and replicating results across samples. Evidence is presented for four symptom clusters (cognitive symptoms, respiratory distress, symptoms of alpha and beta adrenergic activation) and the differential association of each with suicidal ideation and attempts. Symptoms of alpha adrenergic activation predicted prior suicide attempt whereas cognitive symptoms predicted prior suicidal ideation. These findings were independent of comorbid major depressive disorder. It is suggested that assessment of suicide risk in the community includes the presentation of cognitive symptoms and symptoms related to alpha adrenergic activation.

Investigation of Social, Emotional, and Cognitive Factors with Effect on Suicidal Behaviour in Adolescents with Depression

INTRODUCTION

Our study aimed at investigating social, emotional, and cognitive factors playing a role in the development of suicidal ideation in depressed adolescents and its turning into a suicide attempt.

METHOD

Sixty-three adolescents (48 female, 15 male) aged 12 to 18 years were included in the study. In face-to-face interviews, suicide ideation, suicide plans, and previous suicide attempts were evaluated, sociodemographic data were collected. Additionally, the Children's Depression Inventory, State-Trait Anxiety Inventory (STAI-I, II), Beck Hopelessness Scale, Coopersmith Self-Esteem Inventory, Multidimensional Scale of Perceived Social Support, Strengths and the Difficulties Questionnaire (SDQ) parent forms were applied. SPSS version 13.0 for Windows was used for statistical analysis.

RESULTS

It has been established that in the last six months, 71.4% of cases (n=45) had suicidal ideation and 27% (n=17) attempted suicide. Factors associated with suicidal ideation in depressed adolescents were: high depression and anxiety levels, hopelessness and low self-esteem (p<0.05). Factors associated with suicide attempts were: separated family background, lower perceived family support and high rates of conduct difficulties (p<0.05). Patients with suicide attempt differed from patients with suicidal ideation but without suicide attempt in lower perceived family support only (p<0.05).

DISCUSSION

It is thought that keeping in mind the factors associated with the development of suicidal ideation and its turning into a suicide attempt, will help clinicians in preventing suicide attempts in depressed adolescents.

Astrocyte atrophy and immune dysfunction in self-harming macaques

Background

Self-injurious behavior (SIB) is a complex condition that exhibits a spectrum of abnormal neuropsychological and locomotor behaviors. Mechanisms for neuropathogenesis could include irregular immune activation, host soluble factors, and astrocyte dysfunction.

Methods

We examined the role of astrocytes as modulators of immune function in macaques with SIB. We measured changes in astrocyte morphology and function. Paraffin sections of frontal cortices from rhesus macaques identified with SIB were stained for glial fibrillary acidic protein (GFAP) and Toll-like receptor 2 (TLR2). Morphologic features of astrocytes were determined using computer-assisted camera lucida.

Results

There was atrophy of white matter astrocyte cell bodies, decreased arbor length in both white and gray matter astrocytes, and decreased bifurcations and tips on astrocytes in animals with SIB. This was combined with a five-fold increase in the proportion of astrocytes immunopositive for TLR2.

Conclusions

These results provide direct evidence that SIB induces immune activation of astrocytes concomitant with quantifiably different morphology.

Parent-child conflict and suicide rumination in college students: the mediating roles of depressive symptoms and anxiety sensitivity

OBJECTIVE

Parent-child conflict, depressive symptoms, and anxiety sensitivity have each been identified as risk factors for suicide ideation in college students. This study examined the relations among these risk factors and suicide rumination utilizing transition theory to guide the hypothesized relations.

PARTICIPANTS

Undergraduate college students participated in this study in the spring of 2012 (January to May).

METHODS

Participants completed self-report measures of parent-child conflict, depressive symptoms, anxiety sensitivity, and suicide rumination, among other measures. Hypothesized pathways and mediation were tested using path analysis.

RESULTS

Suicide rumination was positively and uniquely predicted by depressive symptoms, anxiety sensitivity, and parent-child conflict. The relation between parent-child conflict and suicide rumination was, in part, accounted for by depressive symptoms and anxiety sensitivity.

CONCLUSIONS

Results suggest that it would be advisable for clinicians to assess for students' conflicts with their parents in conjunction with their levels of depression and anxiety when assessing for suicide risk.

College students' responses to mental health status updates on Facebook

Facebook is widely used by the college population, and previous research has shown that mental health references on Facebook are common. Focus groups of college students were held to determine their views of mental health references seen in their peers' Facebook profiles. Students' views of mental health references varied from being serious calls for help, to being jokes or attention-seeking behavior. Responses to mental health references depended on the participants' offline relationship with the poster. Students would contact close friends through a phone call or in-person conversation, but would not approach acquaintances. The prevalence of mental health references on Facebook, and the awareness of these references by college students, may present opportunities for future peer intervention efforts.

Internet-based screening for suicidal ideation in common mental disorders

BACKGROUND

Common mental disorders have been found to be related to suicidal ideation and behavior. Research in the field of web-based interventions for common mental disorders, however, usually excludes participants with a suicidal risk, although a large proportion of participants might suffer from suicidal ideation.

AIMS

To investigate the prevalence of suicidal ideation in common mental disorders in an online sample.

METHOD

In total, 502 participants completed nine web-based questionnaires on common mental disorders, of which 120 were also interviewed by telephone to obtain a diagnosis. Logistic regression analyses were applied to investigate associations between disorders and suicidal ideation.

RESULTS

Based on web-based self-report, 53% of participants had some form of suicidal ideation. Fewer participants reported suicidal ideation during the interview by telephone. Depression (multivariate odds ratio 7.1), generalized anxiety disorder (2.1), social phobia (2.1), and posttraumatic stress disorder (1.7) were significantly associated with suicidal ideation, while a higher number of comorbid common mental disorders increased the risk.

CONCLUSION

Researchers and clinicians should be aware that one out of every two helpseekers on the internet with common mental disorders may have suicidal ideation. Comorbidity of two or more disorders greatly increase the risk of suicidal ideation.

Suicidal ideation in adult offspring of depressed and matched control parents: childhood and concurrent predictors

BACKGROUND

Suicidal ideation predicts suicide behaviors; however, research is needed on risk factors for suicidal ideation in adults, a common developmental period for first suicide attempts.

AIMS

To examine childhood and concurrent predictors of suicidal ideation among 340 adult offspring of depressed and matched control parents.

METHOD

Parents were assessed at baseline, and adult offspring were assessed 23 years later.

RESULTS

Offspring who reported past-month suicidal ideation (7%) had parents who, 23 years earlier, reported suicidal ideation, psychological inflexibility and use of avoidance coping. Offspring experiencing suicidal ideation were more likely to be unemployed and more depressed, consumed more alcohol and had more drinking problems. They were more anxious and inflexible, had weaker social ties and less cohesive families and had more negative life events and used more avoidance coping. A childhood risk index predicted offspring's suicidal ideation above and beyond concurrent factors.

CONCLUSIONS

Along with concurrent risk factors, poor parental functioning may confer long-term risk for adult suicidal ideation. Interventions to prevent the transmission of suicidal ideation to offspring should focus on ameliorating parental risk factors.

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.
