The Influence of Anxiety Sensitivity on a Wish to Die in Complicated Grief

Factors associated with attitudes toward death and dying in the second half of life: A scoping review

How we think and feel about death and dying affects how we live our lives and our opportunities for healthy aging. This scoping review, using the PRISMA guidelines and drawing on the World Health Organizations public health framework for healthy aging, examined the personal, health and environmental factors associated with attitudes toward death and dying in persons 50 years and older. Most of the 74 eligible studies focused only on negative attitudes to death and few studies investigated the comprehensive range of factors that influence attitudes to death and dying. In the context of population aging and the United Nations Decade of healthy aging (2021-2030) attention to death attitudes and the factors that influence them are imperative to enable current and future generations to age and die well.

The Pathways of Aggression - Differential Indirect Associations Between Anxiety Sensitivity Cognitive Concerns and Suicidality

Background: Suicide prevention efforts have focused on risk factors that help identify people with an increased risk for suicide. One risk factor related to suicide risk is anxiety sensitivity cognitive concerns (ASCC), which is the "fear of going crazy." The association between ASCC and suicidal ideation is hypothesized to result from the depression-distress amplification model, which postulates that ASCC exacerbates feelings of depression and concurrent distress. Furthermore, there is evidence for associations between ASCC/dysregulated anger and dysregulated anger/suicidal ideation. We hypothesized that aggression may provide pathways from ASCC to suicidality. The current study examined how facets of aggression (described as elevated agitation) meditated the association between ASCC and suicidality. Aims: The current study aimed to extend prior research by examining how different facets of aggression mediate the association between ASCC and suicidality. Method: Participants were 440 adults recruited online, 32.7% of whom endorsed experiencing lifetime suicidal ideation. Results: Our hypotheses were partially supported with two significant indirect effects. Results indicated that physical aggression and hostility provided significant indirect effects; however, verbal aggression and anger did not. Limitations: The study was cross-sectional in nature, limiting causal interpretations about the indirect effects. The sample included primarily White participants. Conclusion: Specific facets of aggression provide pathways through which ASCC is associated with suicidality. Aggression may be a catalyst for individuals to progress to suicidality. The current study provides foundational research for continued examination of physical aggression as a catalyst for suicide attempts.

Circulating PACAP peptide and PAC1R genotype as possible transdiagnostic biomarkers for anxiety disorders in women: a preliminary study

Pituitary adenylate cyclase activating polypeptide (PACAP, gene Adcyap1) is a neuropeptide and hormone thought to play a critical role in stress response (Stroth et al., Ann NY Acad Sci 1220:49-59, 2011; Hashimoto et al., Curr Pharm Des 17:985-989, 2011). Research in humans implicates PACAP as a useful biomarker for the severity of psychiatric symptoms in response to psychological stressors, and work in rodent models suggests that PACAP manipulation exerts downstream effects on peripheral hormones and behaviors linked to the stress response, providing a potential therapeutic target. Prior work has also suggested a potential sex difference in PACAP effects due to differential estrogen regulation of this pathway. Therefore, we examined serum PACAP and associated PAC1R genotype in a cohort of males and females with a primary diagnosis of generalized anxiety disorder (GAD) and nonpsychiatric controls. We found that, while circulating hormone levels were not associated with a GAD diagnosis overall (p = 0.19, g = 0.25), PACAP may be associated with GAD in females (p = 0.04, g = 0.33). Additionally, among patients with GAD, the risk genotype identified in the PTSD literature (rs2267735, CC genotype) was associated with higher somatic anxiety symptom severity in females but lower somatic anxiety symptom severity in males (-3.27, 95%CI [-5.76, -0.77], adjusted p = 0.03). Taken together, the associations between the risk genotype, circulating PACAP, and somatic anxiety severity were stronger among females than males. These results indicate a potential underlying biological etiology for sex differences in stress-related anxiety disorders that warrants further study.

Anxiety Sensitivity Differentially Predicts Factors of Interpersonal-Psychological Suicide Risk: A Consideration of Specificity

Recent studies have identified anxiety sensitivity (AS) as a risk factor for suicidality; however, limited work has been performed to understand this risk within the context of the interpersonal-psychological theory of suicide (IPTS; Joiner, 2005). The current study examined the relationship between overall AS, each AS subfactor (cognitive, social, and physical), and the three IPTS domains (perceived burdensomeness, thwarted belongingness, and acquired capability). While each AS subfactor uniquely predicted one IPTS domain, greater overall AS only predicted greater acquired capability, suggesting that assessment of AS at the subfactor level may offer us more information about an individual's interpersonal suicide risk.

The loss of a fellow service member: Complicated grief in post-9/11 service members and veterans with combat-related posttraumatic stress disorder

Bereavement is a potent and highly prevalent stressor among service members and veterans. However, the psychological consequences of bereavement, including complicated grief (CG), have been minimally examined. Loss was assessed in 204 post-9/11, when service members and veterans with combat-related posttraumatic stress disorder (PTSD) took part in a multicenter treatment study. Those who reported the loss of an important person completed the inventory of complicated grief (ICG; n = 160). Over three quarters (79.41%) of the sample reported an important lifetime loss, with close to half (47.06%) reporting the loss of a fellow service member (FSM). The prevalence of CG was 24.75% overall, and nearly one third (31.25%) among the bereaved. CG was more prevalent among veterans who lost a fellow service member (FSM) (41.05%, n = 39) compared to those bereaved who did not (16.92%, n = 11; OR = 3.41, 95% CI: 1.59, 7.36). CG was associated with significantly greater PTSD severity, functional impairment, trauma-related guilt, and lifetime suicide attempts. Complicated grief was prevalent and associated with adverse psychosocial outcomes in veterans and service members with combat-related PTSD. Clinicians working with this population should inquire about bereavement, including loss of a FSM, and screen for CG. Additional research examining CG in this population is needed.
