Suicidal ambivalence: A scoping review.

Suicide Life Threat

Suicidal ambivalence is considered a characteristic condition of suicidal individuals. At the same time, there is a lack of a uniform definition, conception and assessment of suicidal ambivalence. On this background, the current scoping review aims to explore the extent, range, and nature of research activity on suicidal ambivalence and to summarize research findings.

A systematic literature search was conducted in four different databases (PubMed, Psychinfo, Web of Science, and Google Scholar) using an array of search terms (e.g., ambivalence, internal suicide debate, reasons for living and reasons for dying, wish to live and wish to die).

In total, 28 articles published between 1977 and 2023 were included in the scoping review. The study situation lacks a clear definition, conceptualization and operationalization of suicidal ambivalence. Nonetheless, suicidal ambivalence is a common experience in persons contemplating suicide and suicidal ambivalence seems to be present before, during and after a suicide attempt. Suicidal ambivalence is associated with diverse markers of negative/positive mental health as well as suicidal ideation and behavior.

Results point to the relevance of suicidal ambivalence. At the same time, there are large gaps in knowledge about the development, impact and therapeutic responsiveness of suicidal ambivalence.

Do people know how suicidal they will be? Understanding suicidal prospection.

Suicide Life Threat

Little research has been done on how people mentally simulate future suicidal thoughts and urges, a process we term suicidal prospection.

Participants were 94 adults with recent suicidal thoughts. Participants completed a 42-day real-time monitoring study and then a follow-up survey 28 days later. Each night, participants provided predictions for the severity of their suicidal thoughts the next day and ratings of the severity of suicidal thoughts over the past day. We measured three aspects of suicidal prospection: predicted levels of desire to kill self, urge to kill self, and intent to kill self. We generated prediction errors by subtracting participants' predictions of the severity of their suicidal thoughts from their experienced severity.

Participants tended to overestimate (although the average magnitude was small and the modal error was zero) the severity of their future suicidal thoughts. The best fitting models suggested that participants used both their current suicidal thinking and previous predictions of their suicidal thinking to generate predictions of their future suicidal thinking. Finally, the average severity of predicted future suicidal thoughts predicted the number of days participants thought about suicide during the follow-up period.

This study highlights prospection as a psychological process to better understand suicidal thoughts and behaviors.

Implementation of a countywide adult suicide review commission: Development, lessons learned, and recommendations.

Suicide Life Threat

Fatality review is a public health approach designed to inform efforts to prevent fatalities of a certain kind (e.g., suicide, homicide) or in a specific setting or population (e.g., hospitals, youth). Despite extensive literature on fatality review generally, the literature on suicide review teams specifically is scant. The aim of this paper is to: describe the implementation of a local adult suicide review commission, detail examples of initial outcomes and recommendations developed by the commission, and provide recommendations and/or best practices for how to develop and implement an adult suicide review team.

We utilize framing questions from the American Association of Suicidology's psychological autopsy framework. By using these guiding questions in the discussion, members are invited to explore not only the stressors that may have more immediately preceded the suicide event itself, but to situate those stressors in the context of the individual's life course.

Several recommendations proposed by our commission have resulted in tangible outcomes and are detailed using Haddon's Matrix as a guiding prevention planning tool.

We have highlighted the need to move beyond looking at individual-level help-seeking to focus on structural/systemic issues that result in stress or create unsafe environments for at-risk individuals.

The Veterans Crisis Line: Relations among immediate call outcomes and treatment contact and utilization following the call.

Suicide Life Threat

Crisis line callers experience reductions in distress and suicidal ideation and utilize more health care following calls. The purpose of this study was to determine whether changes in distress and suicidal ideation during a call are associated with later healthcare contact and utilization.

Veterans Crisis Line calls from 599 veterans were extracted with call dates between 12/1/2018 and 11/30/2019. Calls were coded for changes in distress and suicidal ideation and linked with VA medical records to obtain healthcare data. Generalized Linear Mixed Modeling was used to examine the associations of changes in distress and suicidal ideation with healthcare contact (yes/no) and utilization (days of treatment) in the month (30 days) following the call.

Reductions in distress were associated with behavioral (i.e., mental and substance use) healthcare utilization, F(1, 596) = 4.52, p = 0.03, and reductions in suicidal ideation were associated with any healthcare utilization, F(1, 596) = 6.45, p = 0.01. Changes in distress and suicidal ideation were not associated with healthcare contact.

Responders need to help resolve distress and suicidal ideation and link callers with treatment. Unresolved distress and suicidal thoughts may signify later problems with treatment utilization. Research is needed to determine causality.

Why did peri-pandemic suicide death rates decrease among non-Hispanic white people while increasing among most people of color?

Suicide Life Threat

While suicides in the United States decreased during the COVID-19 pandemic, statistically significant decreases have been limited to White people throughout a large portion of 2020.

This paper outlines possible explanations for racial/ethnic differences in suicidality in the early pandemic phases.

We propose both distal (i.e., tele-mental health usage, internet and technology access, employment protections, and economic security) and proximal (cultural beliefs, coping strategies, clustering, pulling together, and embracing life) factors that may have helped build and foster community and mental wellness. However, this paper argues these factors did not extend, or did not extend as much, to many communities of color.

We argue that these disparities are due to the myriad effects of discrimination and systemic racism, encapsulated broadly by the minority stress theory, and provide suggestions for relief and research.

Structural adverse childhood experiences associated with suicidal ideation, suicide attempts, and repetitive nonsuicidal self-injury among racially and ethnically minoritized youth.

Suicide Life Threat

High rates of suicidal ideation (SI), suicide attempts (SA), and repetitive nonsuicidal self-injury (NSSI) among some ethnoracially minoritized United States youth populations may be related to adverse childhood experiences (ACEs) with structural roots.

Using the 2013-2019 Minnesota Student Surveys, we assessed associations of student-reported structural ACEs (parental incarceration, housing instability, food insecurity, and foster care involvement) with SI, SA, and repetitive NSSI within the past 12 months using multilevel logistic regression stratified by ethnoracial group (American Indian/Alaskan Native [AIAN], Hmong, other Asian, Black Latino, other Latino, Somali, other Black/African American [AA], Native Hawaiian/Pacific Islander [NHPI], and multiracial), and adjusted for sex, grade, ACEs experienced within one's household, mental health treatment, and perceived safety.

Structural ACEs were strongly associated with increasing SI, SA, and NSSI. At ≥2 structural ACEs, repetitive NSSI rates ranged from 7% to 29% (female), 8% to 20% (male); SA rates ranged from 13% to 35% (female), 10% to 22% (male); and SI rates ranged from 31% to 50% (female), 20% to 32% (male). Black Latino, NHPI, AIAN, and Black/AA students most often reported structural ACE exposures.

Reducing structural ACEs may reduce SI, SA, and repetitive NSSI among ethnoracially minoritized youth populations. Disaggregating diverse youth groups revealed variations in these outcomes that remain hidden when subpopulations are aggregated.

Contribution of basal ganglia activity to REM sleep disorder in Parkinson's disease.

Neurology, Neurosurgery and Psychiatry

Rapid eye movement (REM) sleep behaviour disorder (RBD) is one of the most common sleep problems and represents a key prodromal marker in Parkinson's disease (PD). It remains unclear whether and how basal ganglia nuclei, structures that are directly involved in the pathology of PD, are implicated in the occurrence of RBD.

Here, in parallel with whole-night video polysomnography, we recorded local field potentials from two major basal ganglia structures, the globus pallidus internus and subthalamic nucleus, in two cohorts of patients with PD who had varied severity of RBD. Basal ganglia oscillatory patterns during RBD and REM sleep without atonia were analysed and compared with another age-matched cohort of patients with dystonia that served as controls.

We found that beta power in both basal ganglia nuclei was specifically elevated during REM sleep without atonia in patients with PD, but not in dystonia. Basal ganglia beta power during REM sleep positively correlated with the extent of atonia loss, with beta elevation preceding the activation of chin electromyogram activities by ~200 ms. The connectivity between basal ganglia beta power and chin muscular activities during REM sleep was significantly correlated with the clinical severity of RBD in PD.

These findings support that basal ganglia activities are associated with if not directly contribute to the occurrence of RBD in PD. Our study expands the understanding of the role basal ganglia played in RBD and may foster improved therapies for RBD by interrupting the basal ganglia-muscular communication during REM sleep in PD.

A step forward in conceptualizing psychological closeness/distance to suicide methods: A qualitative approach.

Suicide Life Threat

Suicide is a leading cause of death, making suicide prevention a major public health priority. Increasing understanding of factors influencing suicidal behavior is paramount. Previous research has implicated psychological closeness, characterized by perceptions of how close/distant or attached/detached one feels to a particular object, as a cognitive factor that influences suicidal behavior. However, a better understanding of how psychological closeness to suicide methods is conceptualized by relevant populations is needed to improve its assessment and understand how it may confer risk for suicide.

The goal was to refine the conceptualization of psychological closeness to suicide methods by incorporating feedback from relevant populations. We conducted 30 interviews with those primarily identifying as having lived experience of suicide (n = 10), clinicians who work with suicidal patients (n = 11), and suicide researchers (n = 9). A rigorous thematic approach using NVivo software was used to uncover common themes.

Primary themes included familiarity, comfort, and attachment, with one emerging theme of symbolism. We define these themes, provide context to their meaning, and share exemplary quotes across diverse participants.

We consider clinical, research, and policy implications from an interdisciplinary lens and discuss the strengths and limitations of this study.

Picturing self-harm: Investigating flash-forward mental imagery as a proximal and modifiable driver of non-suicidal self-injury.

Suicide Life Threat

Non-suicidal self-injury (NSSI) is theorized to be reinforced by its emotional consequences. Mental images of NSSI are commonly reported as occurring prior to NSSI. Based on the known functional properties of anticipatory mental imagery as an emotional and motivational amplifier, this study investigated whether NSSI mental imagery constitutes a proximal and dynamic mechanism underpinning NSSI risk.

An intensive ecological momentary assessment (EMA) study was conducted to track the occurrence and characteristics of NSSI mental imagery alongside NSSI urge and behavior in naturalistic settings. A sample of N = 43 individuals aged 17 to 24 with a history of repetitive NSSI completed EMA surveys seven times a day for 14 days.

Mental preoccupation in the form of NSSI mental imagery-based flash-forwards to the actions, bodily sensations, and emotional benefits of NSSI was found to occur when NSSI urge was high but not when urge was low. Critically, objective cross-panel analyses showed that higher frequencies of NSSI imagery occurrence predicted greater future NSSI urge and increased likelihood of acting on urge, over and above current urge.

Mental imagery of NSSI is not simply an epiphenomenal by-product of NSSI urge and may constitute a dynamic and proximal novel intervention target.

Minority stressors and suicidal ideation in sexual minority individuals across adulthood.

Suicide Life Threat

Suicidal ideation occurs at relatively high rates among adults identifying as sexual minorities compared to those identifying as heterosexual, and minority stress is one explanation for this disparity. Minority stress is known to associate with increased suicidal ideation, but research on how minority stress associates with suicidal ideation in sexual minority adults across the adult lifespan is lacking.

Data were collected online from 284 sexual minority adults ranging in age from 18 to 85. Participants were recruited from Prolific and completed self-report measures assessing past-month suicidal ideation and multiple sexual minority stressors.

The minority stressors of acceptance concerns, concealment motivation, and difficulty processing one's identity were positively correlated with likelihood of past-month suicidal deation. Age moderated the relationship between two minority stressors and suicidal ideation: identity uncertainty and internalized homonegativity. These relationships were only significant among older adults, compared to middle-age and younger adults.

Specific internalized minority stressors about one's sexual identity were significantly associated with past-month suicidal ideation for older adults. More research is needed on how minority stress impacts recent suicidal ideation for sexual minority adults across the lifespan.

The role of emotional suppression and emotional beliefs in explaining the honor-suicide link.

Suicide Life Threat

Prior research has established individuals living in cultures of honor to be at higher risk for suicide. However, research has yet to examine how emotion regulation may play a role in explaining this link. The current research intended to address if those who endorse honor norms, who are keen to protect their reputation, might engage in emotional suppression as a way to avoid being seen as weak, thus heightening their risk for suicide.

Data were collected using a survey design across three studies (total N = 988). Studies 1 and 2 were cross-sectional designs with MTurk and undergraduate samples. Study 3 was conducted longitudinally using CloudResearch.

Results demonstrated those higher in honor endorsement engage in emotional suppression to avoid being seen as weak (Study 1), that emotional suppression and subsequent depression indirectly explain the relationship between honor endorsement and suicide attempts (Study 2), and that relationships between honor endorsement and changes in suicidal ideation are explained by emotional suppression and depressive symptomology (Study 3).

Findings provide needed insight into the daily emotional experiences of honor endorsers and how it may influence suicidality, providing a point of entry for clinicians to construct meaningful honor-oriented intervention programs.

Modeling the associations between emotion regulation, suicide crisis syndrome and suicidal behavior: Results in community and clinical samples.

Suicide Life Threat

Emotion Regulation (ER) and Suicide Crisis Syndrome (SCS) are psychological processes involved in suicide. Within ER, both the use of rumination and dysfunctional emotion beliefs are associated with suicide. SCS, a pre-suicidal mental state involving cognitive and affective dysregulation, is related to short-term suicide risk.

Here, we first examined associations between ER (beliefs about the uncontrollability of emotions and rumination), SCS and suicide behavior, and second, we test a multistep model in which ER factors are linked to suicide behavior through SCS.

We conducted two cross-sectional studies to address this issue by self-reports. Study 1 used a community sample (N = 421). Study 2 used a clinical sample (N = 70).

Results from both studies showed that beliefs about the uncontrollability of emotions and rumination were associated with higher levels of SCS symptoms and suicide behavior, and that SCS was associated with suicide behavior. In addition, path analyses showed that uncontrollability beliefs were linked to rumination, which in turn was associated with SCS, and this variable mediated the association between ER factors and suicide ideation (in both community and clinical samples) and suicide attempts (in the community sample).

We emphasize the importance of addressing uncontrollability beliefs and rumination in suicide prevention.
