The Association between Anhedonia, Suicidal Ideation, and Suicide Attempts in a Large Student Sample

Depression is a significant risk factor for suicide. Evidence suggests that anhedonia may be a symptom of depression that is uniquely associated with suicidality. However, exactly how anhedonia is related to suicide is unclear. To provide more specific evidence regarding this association, we investigated relationships between anhedonia, suicidal ideation, and suicide attempts. A large combined undergraduate sample completed the novel Specific Loss of Interest and Pleasure Scale (SLIPS), the Center of Epidemiological Studies Depression Scale (CES-D), and the Suicidal Behaviors Questionnaire—Revised (SBQ-R). Anhedonia was associated with suicidal ideation, even when accounting for depressive symptoms. Additionally, anhedonia was not associated with suicide attempts when symptoms of depression were held constant. The current study provides novel evidence regarding the relationship between anhedonia and risk of attempting suicide. Future research can examine the role anhedonia plays in the unfolding of suicidal behavior over time.

How personality, coping styles, and perceived closeness influence help-seeking attitudes in suicide-bereaved adults.

ABSTRACT This study examined the impact of personality, coping, and perceived closeness on help-seeking attitudes in suicide bereaved adults. Participants (n = 418; mean age = 49.50; 90% women, 89.7% Caucasian) completed measures of personality (neuroticism, extraversion, openness, conscientiousness, and agreeableness), coping, and attitudes toward seeking mental health services. Regression analyses revealed neuroticism as the strongest predictor of help-seeking attitudes. Relatively neurotic adult women bereaved by suicide may be at-risk for developing unhealthy coping styles, low stigma indifference, and more negative help-seeking attitudes.

What role do nightmares play in suicide? A brief exploration

The suicide rate in the United States has climbed each year for more than a decade, highlighting the need for greater understanding of, and prevention strategies for suicidal behavior. Nightmares have been shown to be associated with suicidal behavior independent of several psychiatric risk factors for suicide, such as symptoms of depression, anxiety, and posttraumatic stress disorder (PTSD). The specific role of nightmares in contributing to suicide remains unclear due to the difficulty in delineating causal factors. However, the reporting, screening and treatment of nightmares continues to remain rare making progress difficult. Research is beginning to make some progress in uncovering the mechanisms by which nightmares increase suicide risk providing opportunities for intervention and prediction of suicidal behaviors.

The Relationship of Hypomania, Creativity, and Suicidal Ideation in Undergraduates

Elevations in hypomanic symptoms have been linked to high levels of creativity, and clinicians assess hypomania as one means of identifying individuals most at risk for attempting suicide among individuals diagnosed with depression. However, potential relationships between hypomania, creativity (i.e., divergent thinking and creative achievement), and suicidal ideation in college students are seldom investigated. Participants (N = 94) completed the Adult Suicidal Ideation Questionnaire, Hypomania Checklist-32, Creative Achievement Questionnaire, Guilfords Alternative Uses Task, and a demographic questionnaire. Suicidal ideation was significantly correlated with divergent thinking and creative achievement; but neither the active/elated dimension nor the irritable/risk-taking dimension of hypomania was significantly correlated with suicidal ideation, divergent thinking, or creative achievement. Results suggest that those with high creative achievement in architectural design may experience the highest risk for significant suicidal ideation among the creative domains surveyed, with those in visual arts, creative writing, theater/film, and dance being at moderate risk for significant suicidal ideation. Future research should further investigate the relationship between creative achievement, divergent thinking, and suicidal ideation in colleges and universities that have specific graduate and undergraduate programs in the aforementioned creative domains.

Examining components of emotion regulation in relation to sleep problems and suicide risk

BACKGROUND Sleep has emerged as an important factor in elevated risk for suicide and suicidal behaviors; however, the mechanisms accounting for this relationship are poorly understood. Emotion regulation is a well-established correlate of self-injurious behaviors; however, the broad construct has recently been shown to provide limited predictive utility. More nuanced investigations into the processes involved in emotion regulation may address this gap. This study sought to examine the mediating role of emotion regulation between sleep disturbances and suicide risk, as well as to evaluate a moderated mediation model in which down- and up-regulation of emotions would moderate this mediation. METHODS Participants were 972 adults recruited from a crowdsourcing website (Amazons Mechanical Turk) who completed self-report questionnaires regarding nightmares, suicide risk, and emotion regulation. RESULTS Emotion regulation mediated the direct effect of nightmares on suicide risk and suicide attempts. Downregulation of negative affect moderated the mediation of nightmares on suicide risk more clearly than upregulation of positive affect, and neither component of emotion regulation exhibited moderated mediation in the suicide attempt model. LIMITATIONS Generalizability of our findings from an online community sample will need to be established with replication in other samples. Additionally, we used cross-sectional measures in our mediation models. CONCLUSIONS Downregulation of negative emotions may be particularly salient in relation to the severity of suicide risk and, as a result, relative deficits in this area should be considered when making risk determinations.

Suicidality in sleep disorders: prevalence, impact, and management strategies

Sleep disturbances are associated with suicide-related thoughts and behaviors, and the incidence of sleep concerns and suicide has increased recently in the US. Most published research exploring the sleep–suicidality relation is focused on select sleep disorders, with few reviews offering a comprehensive overview of the sleep–suicidality literature. This narrative review broadly investigates the growing research literature on sleep disorders and suicidality, noting the prevalence of suicide ideation and nonfatal and fatal suicide attempts, the impact of several sleep disorders on suicide risk, and potential sleep-disorder management strategies for mitigating suicide risk. Aside from insomnia symptoms and nightmares, there exist opportunities to learn more about suicide risk across many sleep conditions, including whether sleep disorders are associated with suicide risk independently of other psychiatric conditions or symptoms. Generally, there is a lack of randomized controlled trials examining the modification of suicide risk via evidence-based sleep interventions for individuals with sleep disorders.

Differentiating Single and Multiple Suicide Attempters: What Nightmares Can Tell Us That Other Predictors Cannot

STUDY OBJECTIVES Although nightmares have been associated with suicidal behavior beyond well-known risk factors, the association between nightmares and multiple suicide attempts remains largely unexplored. This study addressed this gap in the literature by examining whether nightmares differentiated between individuals who reported single versus multiple suicide attempts. The individual contributions of nightmare frequency, distress/severity, and chronicity were also investigated to determine which variable contributed the most variance. METHODS Participants (n = 225) were recruited as part of a larger data collection through Amazon Mechanical Turk, an online crowdsourcing venue. Participants reported attempting suicide once (n = 107 individuals), multiple times (n = 118), or never (n = 791). Nightmare frequency, distress, and chronicity were assessed with the Disturbing Dreams and Nightmares Severity Index. RESULTS Nightmare frequency differentiated multiple from single suicide attempters, even after controlling for symptoms of depression, posttraumatic stress disorder, insomnia, nightmare severity/distress, nightmare chronicity, and age (P = .019). Comparison participants, those not reporting suicide attempts, reported a significantly lower level of nightmare frequency than those reporting single or multiple suicide attempts. CONCLUSIONS Inconsistent with past research, this study showed that nightmare frequency, and not nightmare chronicity or severity/distress, differentiated between single and multiple suicide attempters. This outcome suggests that the number of nightmares experienced may be more pertinent in predicting repeat suicide attempts than their duration or perceived severity. Study limitations include a cross-sectional design, a convenience sampling approach, a lack of control for previous treatment or length of time since last attempt, and a retrospective nightmare measure.

Psychiatric Illness and Sleep in Older Adults: Comorbidity and Opportunities for Intervention

This article reviews the literature examining the association between sleep disorders and psychopathology among older adults. Similar to the younger adult literature, the authors found that sleep disorders are robustly associated with anxiety, depression, dementia, and suicidal behavior in late life. Clinical implications and opportunities for intervention are discussed.

Predicting verbal fluency using Word Reading: Implications for premorbid functioning

ABSTRACT The estimation of premorbid general intellectual functioning using word reading tests has a rich history of validation and is a common assessment practice for neuropsychologists. What is less well-researched is the approach used to estimate premorbid functioning of non-intellectual domains, such as executive functions, including verbal fluency. The current study evaluated this relationship with 41 adult college students who completed the Word Reading subtest of the Wechsler Individual Achievement Test-Second Edition (WIAT-II) and the Verbal Fluency test from the Delis–Kaplan Executive Function System (D-KEFS). Path analysis indicated that only Letter Fluency (a measure of phonemic fluency) was statistically significantly related to Word Reading and the relationship was somewhat weak. The relationship between Category Fluency (a measure of semantic fluency) and Category Switching (a measure of verbal fluency cognitive set-shifting) to Word Reading was nonsignificant. Participants also completed the Wechsler Adult Intelligence Scale-Third Edition (WAIS-III), and as expected a strong relationship was found between Word Reading and the Verbal IQ (VIQ), Performance IQ (PIQ), and Full Scale Intelligence Quotient (FSIQ). Results of this study strongly suggest that caution be exercised when extrapolating an estimate of premorbid verbal fluency abilities from measures of word reading.
