Understanding and managing suicide risk

Crisis Management in Social Service Call Centers

Call centers offering social services receive calls from a diverse range of people with varied presenting concerns. Although these centers are not typically designed to assist callers in crisis, unlike suicide prevention or crisis lines, they still encounter a small but significant number of calls from people in active crisis. This article serves as a case study to highlight the importance of crisis intervention readiness and to provide guidelines for non-crisis-oriented call centers on managing crisis calls. It features procedures used by Kick It California (KIC), a tobacco cessation quitline, as a sample blueprint. KIC's crisis management protocol is offered, including guidelines for assessing risk levels and implementing emergency procedures. Additionally, the article outlines strategies for quality assurance as well as ethical and legal considerations, as foundational elements for crisis management procedures in social service call centers.

A systematic review of the studies testing the integrated motivational-volitional model of suicidal behaviour

Despite the influence of the integrated motivational-volitional (IMV)1 model on research and practice, the supporting literature has not been systematically synthesised. This systematic review aims to synthesise the literature testing the IMV model of suicidal behaviour. Using citation and database searching, PsycINFO, EMBASE, PubMed, Web of Science, and Google Scholar were searched for studies referencing the IMV model (last searched on 28th March 2023). Included studies empirically tested the hypotheses of the model. Quality assessment was conducted using the National Institute of Health tool. Findings from 98 records (100 studies, 138,365 participants) were narratively synthesised. Results from studies directly testing the hypothesised pathways of the model supported the defeat-entrapment-suicidal ideation pathway of the IMV model. Case-control studies comparing differences between control, ideation, and enactment groups were consistent with hypotheses in univariate and cross-sectional analyses. However, support for the model was mixed for case-control multivariate and prospective studies. Due to low overlap in variables studied, the role of specific pre-motivational phase variables and stage-specific moderators was inconclusive. The studies received overall good quality ratings. The IMV model presents a promising framework for understanding and preventing suicide. Defeat, entrapment, and key variables may be useful in informing suicide prevention measures.

Anxiety in adolescents and subsequent risk of suicidal behavior: A systematic review and meta-analysis

BACKGROUND

Suicide is a major public health concern, and anxiety is a prevalent developmental challenge in adolescents closely linked to suicidal behavior. This study aimed to assess the association between anxiety in adolescents and subsequent risk of suicidal behavior through a meta-analysis, offering crucial insights for suicide prevention.

METHODS

Six bibliographic databases were comprehensively searched to clarify the association between adolescents anxiety and subsequent risk of suicidal behavior. We used a fixed-effects model to determine the total pooled effect size estimate and reported odds ratios and the corresponding 95 % confidence intervals. Subgroup analysis, sensitivity analysis and publication bias analysis were conducted with Stata version 15.1.

RESULTS

The findings revealed a significant association between anxiety in adolescents and subsequent suicidal behavior (OR = 2.33, 95 % CI [2.00, 2.71]). Subgroup analyses indicated differences in mean effect size estimates based on clinical diagnoses and self-reported measures used to assess anxiety. The correlation strength between adolescent anxiety and subsequent suicidal behavior increased with a longer follow-up period. Furthermore, adolescents anxiety was associated with increased risk of subsequent suicidal ideation (OR = 1.97, 95 % CI [1.72, 2.25]) and attempts (OR = 3.56, 95 % CI [2.49, 5.07]). Finally, boys (OR = 2.41, 95 % CI [1.67, 3.47]) with anxiety had a greater risk of subsequent suicidal behavior than girls (OR = 2.02, 95 % CI [1.47, 2.78]).

CONCLUSION

This study revealed that adolescents anxiety increases the risk of suicidal behavior, including suicidal ideation and attempts. Consequently, there is a critical need for timely interventions tailored to adolescents with anxiety to prevent future instances of suicide.

Identifying Subgroups of Suicidality Among Adolescents and Influencing Factors Using Latent Class Analysis

OBJECTIVE

We aimed to classify subgroups of suicidality among adolescents and identify the influencing factors of the classification of these latent classes.

METHODS

Suicidal thought, plans, and attempts as well as the feelings of sadness/hopelessness and loneliness were utilized as indicators to derive the suicidality classes. Additionally, health behaviors, such as dietary habits, physical activity, experiences of violence victimization, sexual activity, and deviant behavior, along with demographic factors, such as sex, school year, grades, and household income, were considered as influencing factors. The analysis utilized data from the 18th Youth Health Behavior Survey (2022) conducted by the Korea Disease Control and Prevention Agency, involving 51,850 middle and high school students.

RESULTS

The findings revealed three latent classes of suicidality among adolescents: "active suicidality," "passive suicidality," and "non-suicidality." The influencing factor analysis indicated that all factors, with the exception of high-intensity physical activities, significantly influenced the classification of latent classes of suicidality. Notably, walking exercise and the frequency of exercise during physical education class were found to be factors that differentiated between active and passive suicidality within the suicidality classes.

CONCLUSION

This study employed nationwide data to identify the exhibited suicidality classes among adolescents and tested the influencing factors necessary for predicting such classes. The study's findings offer valuable insights for policy development in suicide prevention and suggest the need for developing customized interventions tailored to each identified class.

Ethological Problems with the Interpersonal Theory of Suicide

Joiner and colleagues' Interpersonal Theory of Suicide (IPTS), a prominent "desire-capability" model of suicide-based on the common-sense idea that people take their own lives because they want to, and can-is critiqued from a biological perspective. Tinbergen's ethological "four questions" guide the analysis: evolution, survival value, ontogeny, and proximate causation, each addressing a different aspect of biological understanding. Problems for IPTS emerge with all four. As a parsimonious solution, the desire-capability hypothesis is reconceived as an ultimate, instead of proximate, mode of explanation. By this light, desire and capability for suicide combined in our species' ancestral past, thus making suicide a recurrent survival threat, and driving the evolution of special-purpose defensive adaptations. This stance tallies with the pain-brain theory of the evolution of suicide, and with Joiner and colleagues' own investigation into organismic anti-suicide defenses, which appears to conflict conceptually with IPTS. These defenses' evolved algorithm may make suicide an intrinsically aleatory phenomenon, opaque to usefully accurate prediction. Positive implications for prevention and research are proposed.

Daily Levels and Dynamic Metrics of Affective-Cognitive Constructs Associate With Suicidal Thoughts and Behaviours in Adults After Psychiatric Hospitalization

The period after psychiatric hospitalization is an extraordinarily high-risk period for suicidal thoughts and behaviours (STBs). Affective-cognitive constructs (ACCs) are salient risk factors for STBs, and intensive longitudinal metrics of these constructs may improve personalized risk detection and intervention. However, limited research has examined how within-person daily levels and between-person dynamic metrics of ACCs relate to STBs after hospital discharge. Adult psychiatric inpatients (N = 95) completed a 65-day ecological momentary assessment protocol after discharge as part of a 6-month follow-up period. Using dynamic structural equation models, we examined both within-person daily levels and between-person dynamic metrics (intensity, variability and inertia) of positive and negative affect, rumination, distress intolerance and emotion dysregulation as risk factors for STBs. Within-person lower daily levels of positive affect and higher daily levels of negative affect, rumination, distress intolerance and emotion dysregulation were risk factors for next-day suicidal ideation (SI). Same-day within-person higher rumination and negative affect were also risk factors for same-day SI. At the between-person level, higher overall positive affect was protective against active SI and suicidal behaviour over the 6-month follow-up, while greater variability of rumination and distress intolerance increased risk for active SI, suicidal behaviour and suicide attempt. The present study provides the most comprehensive examination to date of intensive longitudinal metrics of ACCs as risk factors for STBs. Results support the continued use of intensive longitudinal methods to improve STB risk detection. Interventions focusing on rumination and distress intolerance may specifically help to prevent suicidal crises during critical transitions in care.

Tinnitus, Suicide, and Suicidal Ideation: A Scoping Review of Primary Research

Tinnitus (the perception of sound in the absence of any corresponding external source) is highly prevalent and can be distressing. There are unanswered questions about how tinnitus, suicidal thoughts, and suicidal behaviours co-occur and interact. To establish the extent of scientific literature, this scoping review catalogued primary reports addressing the associations between tinnitus, suicidal ideation, attempted suicide, and death by suicide. We searched OvidSP, Medline, EMBASE, PsycINFO, CINAHL, Google Scholar, EThoS, and ProQuest for all studies and case reports on ideation and/or attempted and/or completed suicide in the context of tinnitus. Twenty-three studies were included, and data were charted according to study type. Several epidemiological and other observational studies gave evidence of risk factors and an association between suicidal ideation, suicidal behaviour, and tinnitus. However, there was no evidence of the direction of causality. Qualitative studies are indicated to explore the patient's experience and understand the dynamics of any interaction between tinnitus and suicidal thoughts and behaviours. A theory-informed model of tinnitus and suicide needs to be developed to inform the development of interventions and how tinnitus patients are supported clinically.

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.

Risk assessment in clinical practice: a framework for decision-making in real-world complex systems

Risk assessment in clinical practice is often characterised as a process of analysing information so as to make a judgement about the likelihood of harmful behaviour occurring in the future. However, this characterisation is brought into question when the evidence does not support the current use of risk assessment approaches to predict, or provide probability estimates of, future behaviour in a way that is usable in single instances arising in individual cases. This article sets out a broader and more clinically applicable description of risk assessment which takes account of the wider influences on how this clinical activity takes place. In so doing, it provides a framework to guide clinicians, researchers and authors of practice guidance who are interested in improving approaches to risk assessment.

Utilising the Integrated Motivational Volitional (IMV) model to guide CBT practitioners in the use of their core skills to assess, formulate and reduce suicide risk factors

Cognitive behavioural therapists based in primary care are not usually expected to provide therapy to acutely suicidal individuals or work directly on suicidal thoughts. However, all practitioners should be vigilant about suicide risk and potentially help to reduce vulnerabilities to future suicide risk as part of their routine work. Many of the risk factors and processes hypothesised to play a role in the development of suicidal thinking and behaviours are likely to be evident within the usual content of standard evidence-based protocols for depression or anxiety disorders. In this paper we are suggesting that even within the current primary care remit, (i) an increased awareness of suicide risk vulnerability factors and (ii) using knowledge of a psychological model of suicidal behaviour to inform clinical care are likely to be extremely helpful in structuring clinical formulation and informing interventions.

The mediating role of tolerance for psychological pain in the relationship of childhood trauma to suicidal ideation in individuals with a substance use disorder

OBJECTIVES

The association between childhood trauma and suicidal ideation has been well documented in several populations, including individuals with a substance use disorder (SUD). However, a gap still exists in the literature regarding the mechanisms by which childhood trauma later impacts suicide risk. This cross-sectional study tested the effect of childhood trauma on suicidal ideation, as well as the mediating effect of tolerance for psychological pain (managing the pain and enduring the pain) in that relationship, controlling for the effect of depressive symptoms, in individuals with a SUD.

METHODS

A sample of 102 adults with a SUD participated in the study. Path analysis by structural equation␣modelling tested a mediation model.

RESULTS

Depressive symptoms and lower levels of managing the pain were found to fully mediate the association between childhood trauma and suicidal ideation.

CONCLUSIONS

Our results suggest that depressive symptoms and a lack of ability to manage psychological pain contribute towards explaining why traumatic childhood experiences may result in suicidal cognitions in individuals with SUDs. Moreover, they have relevant implications for prevention and clinical interventions regarding suicidal ideation in this population.

PRACTITIONER POINTS

Childhood trauma relates to suicidal ideation in individuals with a substance use disorder. Depressive symptoms contribute towards explaining why traumatic childhood experiences may result in suicidal cognitions. A lack of ability to manage psychological pain also contributes towards explaining this relationship. The obtained results have relevant implications for the prevention of and clinical intervention for suicidal ideation in SUD individuals.

A systematic review of suicidal behaviour in men: A narrative synthesis of risk factors

RATIONALE

Suicides by men outnumber those by women in every country of the world. To date, there has not been a comprehensive systematic review of risk factors for suicidal behaviour in men to better understand the excess deaths by suicide in men.

OBJECTIVE

The present systematic review seeks to determine the nature and extent of the risk factors to predict suicidal behaviour in men over time.

METHODS

A range of databases (CINAHL, PsycINFO, Web of Science Core Collection, Pubmed, Embase, and Psychology and Behavioural Sciences Collection) were searched from inception to January 2020 for eligible articles. The findings were collated through a narrative synthesis of the evidence.

RESULTS

An initial 601 studies were identified. Following the inclusion and exclusion criteria, there were 105 eligible studies (62 prospective and 43 retrospective) identified. Overall, the risk factors with the strongest evidence predicting suicidal behaviour in men were alcohol and/or drug use/dependence; being unmarried, single, divorced, or widowed; and having a diagnosis of depression. In the prospective studies, the most consistent evidence was for sociodemographic factors (19 risk factors), mental health/psychiatric illness (16 risk factors), physical health/illness (13 risk factors), and negative life events/trauma (11 risk factors). There were a small number of psychological factors (6 factors) and characteristics of suicidal behaviour (3 factors) identified. The findings from the retrospective studies provided further evidence for the risk factors identified in the prospective studies.

CONCLUSIONS

This systematic review has highlighted the wide range of risk factors for suicidal behaviour in men, in this review alone 68 different risk factors were identified. Many factors can interact and change in relevance throughout an individual's life. This review has identified extensive gaps in our knowledge as well as suggestions for future research.

From decision to action: Suicidal history and time between decision to die and actual suicide attempt

A substantial proportion of suicide attempts seem to be realized in a sudden manner. However, it is unclear how suicide attempters showing a rapid transition from the decision to die to acting differ from suicide attempters showing a slower transition regarding their suicidal history. The main aim of this study was to determine the proportion of suicide attempters, who reported a rapid transition (≤5, ≤10, ≤180 min) between their decision to die and their actual attempt. Furthermore, attempter groups (≤ vs. >5, ≤ vs. >10 and ≤ vs. >180 min) were compared regarding suicidal history (ideation, plans, and number of lifetime as well as 12 month suicide attempts) as well as depression, hopelessness and trait impulsivity. In total, 118 inpatients (62.7% female; age: M = 38.71, SD = 14.71) hospitalized due to a recent suicide attempt were assessed using structured clinical interview measures assessing suicidal history and self-report instruments. Thirty-six percent reported a time period of ≤5 min, 44% a time period of ≤10 min and 73% a time period of ≤180 min between their decision to die and their attempt. Participants with a rapid transition (≤5, ≤10, ≤180 min) did not differ from participants with a slower transition (>5, >10, >180 min) regarding suicidal history, depression, hopelessness and trait impulsivity. Taken together, a rapid transition seems common, but nevertheless, rapidly realized suicide attempts cannot necessarily be characterized as impulsive.
