Mental Pain and Suicide: A Systematic Review of the Literature

Mental pain as a mediator in the association between avoidant attachment and suicidal ideation among older men

OBJECTIVES

In the present study, our aim was to deepen the understanding of suicidality in older men by adopting a biopsychosocial approach. The study focused on older men as they face an elevated risk of suicide, surpassing not only other age groups but also exhibiting higher rates compared to women. We examined the contribution of mental pain as a mediator in the association between attachment avoidance and suicidal ideation among older men, taking into consideration the severity of their physical illnesses.

METHODS

Participants were 200 men in Israel, aged ≥65 years, living in the community and without cognitive impairment. Data collection was based on self-report measures of suicidal ideation (Beck Scale for Suicidal Ideation, BSSI), attachment (Experience in Close Relationships, ECR-R), mental pain (Orbach and Mikulincer Mental Pain Scale, OMMP), and the severity of physical illnesses (Cumulative Illnesses Rating Scale, CIRS).

RESULTS

Mental pain was found to mediate the association between attachment avoidance and suicidal ideation, but only among participants with higher levels of physical illnesses.

CONCLUSIONS

Mental pain should be considered as a complication of an avoidant coping strategy, which increases the risk of suicide among older men, especially those suffering from significant physical illnesses. The theoretical and clinical implications of these findings are discussed.

"It was a reflection of myself, that i was weak": The impact of depression on the sense of self - An interpretive phenomenological analysis

The World Health Organisation states that more than 350 million people experience depression globally. The phenomenological changes in individuals experiencing depression are profound Phenomenological research can further researchers' and clinicians' understanding of this experience. This study aimed to gain a phenomenological understanding of how individuals with depression understood and made sense of their experiences. A methodology of interpretative phenomenological analysis was adopted. In-depth semi-structured interviews explored the lived experience of depression for eight individuals. Data were analysed into the superordinate theme Broken Self - Transforming the Self. The superordinate theme developed from the subordinate themes of 'unknown self, loss of self and one's identity', 'desperate for a way out', and thirdly, 'conflict with self and what's known', which related directly to how individuals made sense of their experience of depression. These research findings highlight the human implications of the experience of depression and the limitations of viewing depression from a biological or medical model lens. Understanding the human impact is essential for the effective, holistic practice of mental health nursing.

Psychometric evaluation of the Psychache Scale: A multigroup comparison between white and hispanic undergraduate student drinkers

With psychache being an integral aspect of suicidal and addictive behavior, there is a need for efficient assessment, including generalizability across various racial and ethnic identities. Multigroup Confirmatory Factor Analysis of the Psychache Scale was conducted in the context of 1537 undergraduate college student drinkers (White = 1,171, Hispanic = 366). The alternative bifactor model was a better solution compared to other competing models suggesting that the Psychache Scale is sufficiently unidimensional. There was sufficient support for measurement invariance, which implies that the scale is measuring the same construct across groups. The Hispanic group had a significantly higher latent mean overall psychache score compared to their counterparts. The association of psychache with various adjustment outcomes was also similar across groups. The measure demonstrated robust properties to capture psychological pain. Additional studies need to be done to examine factors influencing psychache, especially among the Hispanic population.

Ecological momentary assessments of cognitive dysfunction and passive suicidal ideation among college students

Cognitive dysfunction (CD), inclusive of specific cognitive content (e.g., hopelessness, unbearability) or impaired cognitive processes (e.g., attentional fixation on suicide, rumination), is a key risk factor for suicidal ideation (SI). This study aimed to evaluate multiple forms of CD using ecological momentary assessment (EMA) to determine the unique contributions of CD to concurrent and prospective SI. Fifty-five college students with a history of SI or non-suicidal self-injury completed EMA surveys measuring momentary CD and passive SI ("Wish to Die" [WTD], "Wish to Stay Alive" [WTL]) four times a day for 14 days (2149 total observations). Passive SI and CD variables showed notable within-person variability. Multiple CD variables were significant predictors of concurrent ideation when examined simultaneously in multilevel models with random intercepts and fixed slopes, and associations were stronger when participants were around others. Controlling for concurrent passive SI, between-person rumination was a significant predictor of prospective WTD, and both within-person unbearability and between-person hopelessness were each predictive of prospective WTL. These findings provide evidence for the roles of specific types of CD in conferring risk for passive SI and highlight potentially malleable factors that can be changed through targeted interventions.

Psychache status and associated contributing factors among the Hakka elderly in Fujian, China

BACKGROUND

Little is known about the state of psychological distress of the elderly in China, and research on specific subgroups such as Hakka older adults is almost lacking. This study investigates psychache and associated factors among Hakka elderly in Fujian, China.

METHODS

The data analysed in this study were derived from China's Health-Related Quality of Life Survey for Older Adults 2018. The Chinese version of the Psychache Scale (PAS) was used to assess the frequency and intensity of psychache in Hakka older adults. Generalized linear regression analysis was conducted to identify the main socio-demographic factors associated with psychache overall and its frequency and intensity.

RESULTS

A total of 1,262 older adults participated, with mean scores of 18.27 ± 6.88 for total PAS, 12.50 ± 4.79 for PAS-Frequency and 5.77 ± 2.34 for PAS-Intensity. On average, females scored higher than males on PAS-Frequency (β = 0.84, 95% CI = 0.34, 1.35) and PAS-Intensity (β = 0.48, 95% CI = 0.22, 0.73). Older adults currently living in towns (β = -2.18, 95% CI = -2.81, -1.54), with their spouse only (β = -3.71, 95% CI = -4.77, -2.65), or with children (β = -3.24, 95% CI = -4.26, -2.22) were more likely to score lower on PAS-Frequency. Conversely, older adults who were regular sleepers (β = -1.19, 95% CI =-1.49, -0.88) or lived with their spouse only (β = -1.25, 95% CI = -1.78, -0.72) were more likely to score lower on PAS-Intensity.

CONCLUSION

Among Hakka elderly, we found a higher frequency and greater intensity of psychache in females, those with poor health status, irregular sleepers, rural residents, solo dwellers, those with below CNY 10,000 in personal savings, and the medically uninsured. The study's findings indicate that policymakers should give more attention to the susceptible population and implement practical interventions to reduce their psychological burden.

Impact of Toxoplasma gondii and Human Microbiome on Suicidal Behavior: A Systematic Review

BACKGROUND

Suicide remains a persistent global health challenge, resisting widespread prevention efforts. According to previous findings, toxoplasmosis is particularly associated with altered decision making, which could lead to risk-taking behavior, thereby increasing the likelihood for suicidal behavior (SB). In addition, discussion about the role of microbiome in psychiatric disorders has emerged lately, which also makes it relevant to investigate its role in the context of SB. Therefore, two systematic reviews are integrated in this paper, and the existing knowledge is comprehensively summarized regarding the association between microbial pathogens and SB.

METHODS

We conducted a systematic search with keywords including SB and Toxoplasma gondii (Suicid* AND Toxoplasm*) and microbiome (Suicid* AND Microbiome AND Microbiota) throughout PubMed and Scopus to retrieve related studies up to 9 November 2023, identifying 24 eligible records. The subjects of the included studies had to have fulfilled the criteria of an SB disorder as defined by DSM-5, and death cases needed to have been defined as suicide.

RESULTS

Most studies reported significant association between toxoplasmosis and SB, suggesting a higher likelihood of SB in the infected population. Regarding the microbiome, only very few studies investigated an association between SB and alterations in the microbiome. Based on six included studies, there were some indications of a link between changes in the microbiome and SB.

CONCLUSION

The cognitive aspects of decision making in T. gondii-infected individuals with SB should be further investigated to unravel the underlying mechanisms. Further sufficiently powered studies are needed to establish a link between SB and alterations in the microbiome.

An analysis of the Painful and Provocative Events Scale: Some painful and provocative findings

This research investigated the latent structure and correlates of the 26-item Painful and Provocative Events Scale (PPES). For a sample of 290 community respondents, results from parallel analysis indicated a 5-factor structure. Based on principal axis factoring with varimax rotation, scales of Intense physicality, Physical and mental trauma, Physical risk taking, Psychopathy, and Body enhancement were constructed, and these demonstrated a pattern of convergent and discriminant correlations with suicide-associated and demographic variables that supported the delineation of these scales as being distinct. In general, results challenge the current scoring of the PPES and, with developed scales being differentially related to demographic variables, indicate that both respondent age and sex require consideration for scale score interpretation.

The Relationship Between Psychache and Suicide Risk With Spiritual Well-Being Levels of Patients Diagnosed With Depression

BACKGROUND: Depression has long been accepted as a serious disability and burden globally, while suicide is a misunderstood and complex cause of death. Psychache is the psychological variable most strongly associated with suicidality. Spirituality is considered an important buffer against stressful events and may help people overcome distress and difficulties. AIMS: This study aims to determine how psychache and suicide risk are related to levels of spiritual well-being in patients with depression. METHODS: Data were collected using the Suicide Probability Scale, the Psychache Scale, and the Spiritual Well-Being Scale. The sample study consisted of 150 Turkish patients diagnosed with depression and receiving psychiatric care. RESULTS: It was found that higher level of spiritual well-being led to decreased risk of suicide and lower level of psychache. Suicide risk increased in parallel to the increasing levels of psychache (p < .001). CONCLUSIONS: It was observed that higher levels of spiritual well-being may promote a significantly lower risk of suicide and lower levels of psychache. Likewise, increasing levels of psychache may lead to an increase in suicide risk.

Text Analysis of Suicide Risk in Adolescents and Young Adults

OBJECTIVE

Suicide is of primary public concern for adolescents and young adults (AYAs) who commonly use social media platforms to express their suicidal thoughts and behaviors. Understanding how AYAs communicate their suicide-related thoughts and behaviors in texts can support early detection of suicide risk from their social media posts. Therefore, this study sought to identify themes relevant to suicide risk in AYAs and explore words or terms used by AYAs when they described suicidal thoughts and behaviors.

METHOD

This secondary data analysis utilized an existing data set collected from 255 AYAs between 12 and 25 years of age, who provided brief descriptions of how they and their peers expressed their experiences of self-harm, suicidal thinking, and attempts. Text analysis was conducted using KH Coder software. Three-step theory of suicide was used to guide a content analysis to explore the key themes from the narratives.

RESULTS

A word co-occurrence network with 24 clusters of words was generated from the text analysis. These word clusters were further grouped into pain or hopelessness, connectedness, and capacity to attempt suicide in the content analysis. Six subthemes corresponding to these three themes were identified to provide detailed information: psychological or physical pain, hopelessness, relationship, help seeking, methods, and outcomes. Moreover, several slang terms and acronyms (e.g., Kermit Sewage Slide, KMS) were also identified.

CONCLUSIONS

The findings of this study, including themes and slang terms and acronyms, are valuable to facilitate the use of terms or phrases within social media texts to identify suicide risk in AYAs.

Mental Pain Correlates with Mind Wandering, Self-Reflection, and Insight in Individuals with Psychotic Disorders: A Cross-Sectional Study

Understanding the cognitive processes that contribute to mental pain in individuals with psychotic disorders is important for refining therapeutic strategies and improving patient outcomes. This study investigated the potential relationship between mental pain, mind wandering, and self-reflection and insight in individuals diagnosed with psychotic disorders. We included individuals diagnosed with a 'schizophrenia spectrum disorder' according to DSM-5 criteria. Patients in the study were between 18 and 65 years old, clinically stable, and able to provide informed consent. A total of 34 participants, comprising 25 males and 9 females with an average age of 41.5 years (SD 11.5) were evaluated. The Psychache Scale (PAS), the Mind Wandering Deliberate and Spontaneous Scale (MWDS), and the Self-Reflection and Insight Scale (SRIS) were administered. Statistical analyses involved Spearman's rho correlations, controlled for potential confounders with partial correlations, and mediation and moderation analyses to understand the indirect effects of MWDS and SRIS on PAS and their potential interplay. Key findings revealed direct correlations between PAS and MWDS and inverse correlations between PAS and SRIS. The mediation effects on the relationship between the predictors and PAS ranged from 9.22% to 49.8%. The largest statistically significant mediation effect was observed with the SRIS-I subscale, suggesting that the self-reflection and insight component may play a role in the impact of mind wandering on mental pain. No evidence was found to suggest that any of the variables could function as relationship moderators for PAS. The results underscore the likely benefits of interventions aimed at reducing mind wandering and enhancing self-reflection in psychotic patients (e.g., metacognitive therapy, mindfulness). Further research will be essential to elucidate the underlying mechanisms.

Interpersonal Needs, Mental Pain, and Hopelessness in Psychiatric Inpatients with Suicidal Ideation

INTRODUCTION

Suicide is a leading cause of death worldwide and models may help the understanding of the phenomenon and ultimately reduce its burden through effective suicide prevention strategies. The Interpersonal Theory of Suicide and Shneidman's Model have tried to describe different unmet needs related to suicidal ideation. The study aims to assess the association between thwarted belongingness, perceived burdensomeness, and suicidal ideation in a sample of psychiatric inpatients and the mediating role of hopelessness and mental pain in this association.

METHODS

112 consecutive adult psychiatric inpatients were administered the Columbia Suicide Severity Rating Scale (C-SSRS), the Italian version of the Interpersonal Needs Questionnaire-15-I (INQ-15-I), the Physical and Psychological Pain Scale, and the Beck Hopelessness Scale (BHS).

RESULTS

Mediation models indicated a significant indirect effect of perceived burdensomeness (with thwarted belongingness as covariates) on suicidal ideation intensity with hopelessness as a mediator. When thwarted belongingness (controlling for perceived burdensomeness as a covariate) was included in a model as an independent variable, direct and indirect effects on suicidal ideation intensity were not significant.

CONCLUSIONS

Psychosocial interventions focusing on identifying and decreasing the perception of being a burden for others and the feeling hopeless could represent a powerful pathway for reducing suicidal ideation. Moreover, the attention toward unmet interpersonal needs may help increase and focus clinical discussions on risk factors, which may help engagement toward psychiatric care and downsize the stigma related to suicide. Raising awareness toward mental health topics is a goal of healthcare services globally.

Child maltreatment and youth suicide risk: A developmental conceptual model and implications for suicide prevention

Experiences of child abuse and neglect are risk factors for youth suicidal thoughts and behaviors. Accordingly, suicide risk may emerge as a developmental process that is heavily influenced by the rearing environment. We argue that a developmental, theoretical framework is needed to guide future research on child maltreatment and youth (i.e., adolescent and emerging adult) suicide, and to subsequently inform suicide prevention efforts. We propose a developmental model that integrates principles of developmental psychopathology and current theories of suicide to explain the association between child maltreatment and youth suicide risk. This model bears significant implications for future research on child maltreatment and youth suicide risk, and for suicide prevention efforts that target youth with child maltreatment experiences.

A Systematic Review of MRI Studies and the "Emotional paiN and social Disconnect (END)" Brain Model of Suicidal Behavior in Youth

Introduction

Risk of suicidal ideation and suicidal behaviors greatly increases during adolescence, and rates have risen dramatically over the past two decades. However, few risk factors or biomarkers predictive of suicidal ideation or attempted suicide have been identified in adolescents. Neuroimaging correlates hold potential for early identification of adolescents at increased risk of suicidality and risk stratification for those at high risk of suicide attempt.

Methods

In this systematic review, we evaluated neural regions and networks associated with suicidal ideation and suicide attempt in adolescents derived from magnetic resonance imaging (MRI) studies. A total of 28 articles were included in this review.

Results

After descriptively synthesizing the literature, we propose the Emotional paiN and social Disconnect (END) model of adolescent suicidality and present two key neural circuits: (1) the emotional/mental pain circuit and (2) the social disconnect/distortion circuit. In the END model, the emotional pain circuit-consisting of the cerebellum, amygdala, and hippocampus-shows similar aberrations in adolescents with suicidal ideation as in those with a history of a suicide attempt (but to a smaller degree). The social disconnect circuit is unique to adolescent suicide attempters and includes the lateral orbitofrontal cortex (OFC), the temporal gyri, and the connections between them.

Conclusion

Our proposed END brain model of suicidal behavior in youth, if confirmed by future prospective studies, can have implications for clinical goals of early detection, risk stratification, and intervention development. Treatments that target emotional pain and social disconnect may be ideal interventions for reducing suicidality in adolescents.

The Mediating Role of Tolerance for Psychological Pain in the Relationship Between Different Types of Childhood Traumatic Experiences and Suicidal Ideation

The aim of the present research was to evaluate the mediating effects of facets of the tolerance for psychological pain on the relationship between childhood trauma and suicidal ideation. A sample of 437 community individuals and a sample of 316 college students participated. For the community sample, managing the pain mediated the relationship between childhood trauma, the different types of traumatic experiences and suicidal ideation. In the college sample, managing the pain and enduring the pain mediated the relationship between childhood trauma, the different types of traumatic experiences and suicidal ideation, except for the case of sexual abuse. The present results have potential clinical implications. Mental health professionals should be aware of the long-term consequences of exposure to childhood trauma and need to assess the ability to tolerate psychological pain so as to implement appropriate psychological interventions that help individuals cope with their pain.

An investigation of the relationships between suicidal ideation, psychache, and meaning in life using network analysis

BACKGROUND

Previous studies have investigated the relationships between psychache or meaning in life and suicidal ideation based on sum score of corresponding scale. However, this practice has hampered the fine-grained understanding of their relationships. This network analysis study aimed to conduct a dimension-level analysis of these constructs and the relationships among them in a joint framework, and identify potential intervention targets to address suicidal ideation.

METHODS

Suicidal ideation, psychache, and meaning in life were measured using self-rating scales among 738 adults. A network of suicidal ideation, psychache, and meaning in life was constructed to investigate the connections between dimensions and calculate the expected influence and bridge expected influence of each node.

RESULTS

"Psychache" was positively linked to "sleep" and "despair", while "presence of meaning in life" had negative associations with "psychache", "despair", and "pessimism". The most important central nodes were "sleep" and "despair", and the critical bridge nodes were "presence of meaning in life" and "psychache".

CONCLUSION

These preliminary findings uncover the pathological pathways underlying the relationships between psychache, meaning in life, and suicidal ideation. The central nodes and bridge nodes identified may be potential targets for effectively preventing and intervening against the development and maintenance of suicidal ideation.

Interpersonal and intrapersonal predictors of suicidal thoughts and actions in first-year college students

OBJECTIVE

The aim was to determine the unique predictors of suicide risk in first-year college students.

PARTICIPANTS

First-year students (N = 665) at a Midwestern university participated.

METHODS

An online survey assessed Joiner's interpersonal factors (i.e., thwarted belongingness, perceived burdensomeness, and acquired capability) as well as intrapersonal factors (i.e., perfectionism, self-compassion, emotional intelligence/reactivity, and growth mindset) often associated with suicidal thoughts and actions.

RESULTS

Linear regression indicated that the factor set significantly predicted thoughts, F (12, 632) = 114.90, p < .000, R² = .680, and actions, F (12, 632) = 58.42, p < .000, R² = .526. Perceived burdensomeness, acquired capability, and underrepresented sexual orientation were positive predictors of both thoughts and actions, whereas growth mindset was a negative predictor of thoughts and stressful life events was a positive predictor of actions.

CONCLUSION

The results offer direction for evidence-informed interventions aimed at reducing suicide risk in first-year college students.

Racial Differences in the Relationship Between Pain and Suicide Desire in Older Adults

Older adults are reported to die by suicide at higher rates than the general population. Suicide desire among older adults is associated with pain, and pain experiences have been found to differ based on race. To investigate the relationship between pain and suicidal desire, 437 racially diverse older adults who receive home-based services (home-delivered meals) in the Southeastern region of the United States completed standardized measures of psychological pain, chronic physical pain, and suicidal desire. Results identified race moderated the relationship between pain and suicidal desire, indicating a stronger relationship between pain and suicidal desire among Black older adults than White older adults. Chronic physical pain (i.e., emotional burden) interacted with race to predict Perceived Burdensomeness ( p = .011) and Thwarted Belongingness ( p = .032). Greater attention to pain experiences among Black older adults is warranted, considering the impact of COVID-19 on racial/ethnic minorities’ mental health.

Suicidal Ideation and Obsessive-Compulsive Disorder: Links and Knowledge

Suicidal ideation (SI) is understudied in obsessive-compulsive disorder (OCD). Nonetheless, evidence suggests increased risk for SI in individuals with OCD compared to the general population. Understanding the relationship between SI and OCD involves investigating risk factors associated with SI. Furthering knowledge of links is essential for enhancing outcomes and decreasing experiences of SI through improving treatment interventions. Additionally, increasing awareness of factors that lead SI to suicide attempts (SA) is vital. To best illustrate the current state of knowledge, this scoping review examines risk factors for SI, including symptom profiles or phenotypes, comorbid diagnoses, sociodemographic and lifestyle factors, childhood trauma, and genetic and familial contributions. Important treatment considerations for targeting SI within the context of OCD are detailed with respect to the current evidence for psychotherapy, pharmacology, brain stimulation, and neurosurgery. Gaps in the literature and future directions are identified, broadly with respect to studies examining the treatment of SI within the context of OCD, particular OCD phenotypes, and factors influencing SI in pediatric OCD. Due to the relative novelty of this area of exploration, many unknowns persist regarding onset of SI in OCD, factors contributing to the maintenance of SI in OCD, and relevant treatment protocols. Findings suggest that individuals with previous SI or SA, history of childhood trauma, significant life stress, and psychiatric comorbidities, particularly depression, should be closely monitored and screened for SI.

Decision-making biases in suicide attempters with major depressive disorder: A computational modeling study using the balloon analog risk task (BART)

BACKGROUND

In the last decade, suicidality has been increasingly theorized as a distinct phenomenon from major depressive disorder (MDD), with unique psychological and neural mechanisms, rather than being mostly a severe symptom of MDD. Although decision-making biases have been widely reported in suicide attempters with MDD, little is known regarding what components of these biases can be distinguished from depressiveness itself.

METHODS

Ninety-three patients with current MDD (40 with suicide attempts [SA group] and 53 without suicide attempts [NS group]) and 65 healthy controls (HCs) completed psychometric assessments and the balloon analog risk task (BART). To analyze and compare decision-making components among the three groups, we applied a five-parameter Bayesian computational modeling.

RESULTS

Psychological assessments showed that the SA group had greater suicidal ideation and psychological pain avoidance than the NS group. Computational modeling showed that both MDD groups had higher risk preference and lower ability to learn and adapt from within-task observations than HCs, without differences between the SA and NS patient groups. The SA group also had higher loss aversion than the NS and HC groups, which had similar loss aversion.

CONCLUSIONS

Our BART and computational modeling findings suggest that psychological pain avoidance and loss aversion may be important suicide risk factor that are distinguishable from depression illness itself.

Association between psychological pain and suicidal ideation among men with substance use disorder: a moderated mediation model

Previous studies have found that people with substance use disorder are associated with significantly higher odds of suicidal ideation than the general population. Psychological pain and emotional regulation are considered protective factors for suicidal ideation, but the interaction process is not clear. In this study, we investigated the effects of psychological pain on suicidal ideation and constructed a moderated mediation model. 445 men with substance use disorder in China were recruited to complete the Chinese version of the Psychological Pain Scale, Regulatory Emotional Self-efficacy Scale, Suicidal Ideation Scale, and Intolerance of Uncertainty Scale. The results demonstrated that psychological pain significantly and positively predicted suicidal ideation among people with substance use disorder, and that regulatory emotional self-efficacy played a mediating role between psychological pain and suicidal ideation. Intolerance of uncertainty moderated the top and bottom halves of the intermediate process paths. This study suggests that intolerance of uncertainty and regulatory emotional self-efficacy can be improved by interventions among people with substance use disorder, which in turn can reduce their suicidal ideation and improve quality of life.

How to measure mental pain: a systematic review assessing measures of mental pain

QUESTION

Although mental pain is present in many mental disorders and is a predictor of suicide, it is rarely investigated in research or treated in care. A valid tool to measure it is a necessary first step towards better understanding, predicting and ultimately relieving this pain.

STUDY SELECTION AND ANALYSIS

Following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines, we performed a systematic review to identify all published standardised measures of mental pain. We used qualitative content analysis to evaluate the similarity of each measure, quantified via Jaccard Index scores ranging from no similarity (0) to full similarity (1). Finally, using the Consensus-based Standards for the selection of health Measurement INstruments (COSMIN) methodology, we evaluated each measure's development (assessing 35 features), its content validity (31 features) and if the latter was rated at least adequate, its other psychometric properties.

FINDINGS

We identified 10 self-reported scales of mental pain in 2658 screened studies relying on diverse definitions of this construct. The highest average similarity coefficient for any given measure was 0.24, indicative of weak similarity (individual pairwise coefficients from 0 to 0.5). Little to no information was provided regarding the development and the content validity of all 10 scales. Therefore, their development and content validity were rated 'inadequate' or 'doubtful'.

CONCLUSIONS AND CLINICAL IMPLICATIONS

There is not enough evidence of validity to recommend using one measure over others in research or clinical practice. Heterogeneous use of disparate measures across studies limits comparison and combination of their results in meta-analyses. Development by all stakeholders (especially patients) of a consensual patient-reported measure for mental pain is needed.

Potential paths to suicidal ideation and suicide attempts among high-risk women

Although men are more likely to die by suicide, women experience a greater and more rapidly increasing rate of suicidal ideation (SI) and are 3 times more likely to attempt suicide than men. Despite this increased risk, little is known about factors that contribute to SI or suicide attempts (SA) among women. We examined factors associated with SI and SA among women and identified mood-related symptoms that differentiate women who reported attempting suicide from those who did not. Women at elevated risk for depression from across the U.S. (N = 3372; age 18 to 90) completed a survey regarding depression, anxiety, sociodemographic and reproductive status, behavioral/mental health history, and exposure to adversity. Structural equation modeling and logistic regression were used to analyze the data. Variables with the most significant relationships to SI were severity of depression (OR = 5.2, p = 0.000) and perceived stress (OR = 1.18, p = 0.000) while frequency of suicidal thoughts (OR = 3.3, p = 0.000), family history of a depression diagnosis (OR = 1.6, p = 0.000) and exposure to violence (OR = 1.9, p = 0.000) had the strongest association with SA. Childhood abuse/trauma was associated with SA (OR = 1.13, p = 0.000) but not SI. 'Feeling bad about themselves, a failure, or having let themselves or their family down' was the symptom that most clearly differentiated women who attempted suicide from women who reported suicidal ideation but no SA. The salience of childhood abuse and domestic/community violence to women's risk for a suicide attempt reinforces previous findings that these adversities may differentiate suicide risk for women versus men. Continued research is essential to understand varied paths that may lead to suicidal behavior among women, some which appear unrelated to the frequency or intensity of their suicidal thoughts.

Sleep loss suicidal ideation: the role of trait extraversion

Background: It is known that sleep disturbance is associated with increased suicidal thinking. Moreover, completed suicides, when adjusted for the proportion of the populace that is awake at a given time, are more probable during the late night/early morning hours. Despite these concerns, no studies have examined the role of trait-like individual differences in vulnerability to suicidal ideation during sleep deprivation or insomnia. In two separate studies, we examined whether the trait of extraversion is predictive of changes in suicidal thinking following two nights of sleep deprivation and among individuals meeting the criteria for insomnia.

Methods:Study 1: Twenty-five healthy military personnel (20 males), ages 20–35 completed the NEO-PI-R Extraversion scale and the Suicidal Ideation (SUI) scale of the Personality Assessment Inventory (PAI). Participants completed 77 h of continuous sleep deprivation. After 56 h of sleep deprivation, participants completed the SUI scale a second time. We predicted a change in SUI scores from baseline extraversion. Study 2: 2,061 adults aged 18–79 (900 males) were divided into two groups based on the clinical threshold (≥ 10) on the Insomnia Severity Index (ISI) and completed measures of extraversion and depression, including the suicide item of the Patient Health Questionnaire-9 (PHQ9).

Results:Study 1: After controlling for the caffeine group and changes in PAI Depression, Extraversion scores were used to predict changes in SUI scores using stepwise multiple linear regression. Higher Extraversion was significantly associated with increased non-clinical suicidal ideation following sleep loss, β = 0.463, partial r = 0.512, p = 0.013. Study 2: After controlling for depression, the effect of insomnia on suicidal ideation was moderated by trait extraversion (p < 0.0001). Overall, the presence or absence of insomnia had little effect on individuals low in trait extraversion (i.e., introverts), but insomnia was associated with significantly higher suicidal ideation among high trait extraverted individuals.

Conclusions: Higher trait extraversion was associated with increased vulnerability to suicidal ideation between rested baseline and total sleep deprivation and was associated with greater suicidal ideation among those meeting criteria for clinically severe insomnia. These findings point to a potential trait-like vulnerability factor that may further our understanding of sleep disruption in the phenomenology of suicide.

Exploring the Suicide Mechanism Path of High-Suicide-Risk Adolescents-Based on Weibo Text Analysis

BACKGROUND

Adolescent suicide can have serious consequences for individuals, families and society, so we should pay attention to it. As social media becomes a platform for adolescents to share their daily lives and express their emotions, online identification and intervention of adolescent suicide problems become possible. In order to find the suicide mechanism path of high-suicide-risk adolescents, we explore the factors that influence is, especially the relations between psychological pain, hopelessness and suicide stages.

METHODS

We identified high-suicide-risk adolescents through machine learning model identification and manual identification, and used the Weibo text analysis method to explore the suicide mechanism path of high-suicide-risk adolescents.

RESULTS

Qualitative analysis showed that 36.2% of high-suicide-risk adolescents suffered from mental illness, and depression accounted for 76.3% of all mental illnesses. The mediating effect analysis showed that hopelessness played a complete mediating role between psychological pain and suicide stages. In addition, hopelessness was significantly negatively correlated with suicide stages.

CONCLUSION

mental illness (especially depression) in high-suicide-risk adolescents is closely related to suicide stages, the later the suicide stage, the higher the diagnosis rate of mental illness. The suicide mechanism path in high-suicide-risk adolescents is: psychological pain→ hopelessness → suicide stages, indicating that psychological pain mainly affects suicide risk through hopelessness. Adolescents who are later in the suicide stages have fewer expressions of hopelessness in the traditional sense.

High depression symptomatology and mental pain characterize suicidal psychiatric patients

BACKGROUND

Symptoms of depression are transdiagnostic heterogenous features frequently assessed in psychiatric disorders, that impact the response to first-line treatment and are associated with higher suicide risk. This study assessed whether severe mental pain could characterize a specific phenotype of severely depressed high-risk psychiatric patients. We also aimed to analyze differences in treatments administered.

METHODS

2,297 adult patients (1,404 females and 893 males; mean age = 43.25 years, SD = 15.15) treated in several Italian psychiatric departments. Patients were assessed for psychiatric diagnoses, mental pain, symptoms of depression, hopelessness, and suicide risk.

RESULTS

More than 23% of the patients reported high depression symptomatology and high mental pain (HI DEP/HI PAIN). Compared to patients with lower symptoms of depression, HI DEP/HI PAIN is more frequent among females admitted to an inpatient department and is associated with higher hopelessness and suicide risk. In addition, HI DEP/HI PAIN (compared to both patients with lower symptoms of depression and patients with higher symptoms of depression but lower mental pain) were more frequently diagnosed in patients with personality disorders and had different treatments.

CONCLUSIONS

Patients reporting severe symptoms of depression and high mental pain presented a mixture of particular dangerousness (high trait hopelessness and the presence of suicide ideation with more frequency and less controllability and previous suicide behaviors). The presence of severe mental pain may act synergically in expressing a clinical phenotype that is likewise treated with a more complex therapeutic regime than that administered to those experiencing symptoms of depression without mental pain.

Pharmacological Strategies for Suicide Prevention Based on the Social Pain Model: A Scoping Review

Suicidal behaviour is a public health problem whose magnitude is both substantial and increasing. Since many individuals seek medical treatment following a suicide attempt, strategies aimed at reducing further attempts in this population are a valid and feasible secondary prevention approach. An evaluation of the available evidence suggests that existing treatment approaches have a limited efficacy in this setting, highlighting the need for innovative approaches to suicide prevention. Existing research on the neurobiology of social pain has highlighted the importance of this phenomenon as a risk factor for suicide, and has also yielded several attractive targets for pharmacological strategies that could reduce suicidality in patients with suicidal ideation or a recent attempt. In this paper, the evidence related to these targets is synthesized and critically evaluated. The way in which social pain is related to the “anti-suicidal” properties of recently approved treatments, such as ketamine and psilocybin, is examined. Such strategies may be effective for the short-term reduction in suicidal ideation and behaviour, particularly in cases where social pain is identified as a contributory factor. These pharmacological approaches may be effective regardless of the presence or absence of a specific psychiatric diagnosis, but they require careful evaluation.

Scale of psychological pain: Spanish adaptation of the Psychache Scale in young adults

INTRODUCTION

Psychological pain is understood as an intolerable and disturbing mental state characterized by an internal experience of negative emotions. This study was aimed at making a Spanish adaptation of the Psychache Scale by Holden and colleagues in a sample of young adults.

MATERIAL AND METHODS

The scale evaluates psychological pain as a subjective experience. It is composed of 13 items with a Likert-type response format. Following the guidelines of the International Tests Commission for the adaptation of the test, we obtained a version conceptually and linguistically equivalent to the original scale. Through an online questionnaire, participants completed the psychological pain scale along with other scales to measure depression (BDI-II), hopelessness (Beck's scale of hopelessness) and suicide risk (Plutchik suicide risk scale). The participants were 234 people (94 men, 137 women and three people who identified as a different sex) from 18 to 35 years old.

RESULTS

The EFA showed a one-factor solution, and the FCA revealed adequate indexes of adjustment to the unifactorial model. It also showed good reliability of the test scores. The evidence of validity of the scale in relation to the other variables showed high, positive and statistically significant correlations with depression, hopelessness, suicidal ideation and suicidal risk.

CONCLUSION

In summary, this Spanish adaptation of the Psychache Scale could contribute to improving the evaluation of both the patient with suicide risk and the effectiveness of psychological therapy, as well as suicidal behaviour prevention and intervention.

Assessing Mental Pain as a Predictive Factor of Suicide Risk in a Clinical Sample of Patients with Psychiatric Disorders

According to contemporary suicidology, mental pain represents one of the main suicide risk factors, along with more traditional constructs such as depression, anxiety and hopelessness. This work aims to investigate the relationship between the levels of mental pain and the risk to carry out suicide or suicide attempt in the short term in order to understand if a measurement of mental pain can be used as a screening tool for prevention. For this purpose, 105 outpatients with psychiatric diagnosis were recruited at the university hospital of Varese during a check-up visit and were assessed by using psychometric scales of mental pain levels, hopelessness, anxiety and depression. Clinical and sociodemographic variables of the sample were also collected. A period of 18 months following the recruitment was observed to evaluate any suicides or attempted suicides. Subjects numbering 11 out of 105 committed an attempted suicide. From statistical analyses, high values of the Beck Depression Inventory (BDI-II), Mental Pain Questionnaire (OMMP) and Hamilton Rating Scale for Depression (HAM-D) scales showed a significant association with the risk of carrying out a suicide attempt and, among these, OMMP and BDI-II showed characteristics of good applicability and predictivity proving suitable to be used as potential tools for screening and primary prevention of suicidal behavior.

High School Football and Risk for Depression and Suicidality in Adulthood: Findings From a National Longitudinal Study

Background

There is growing public concern regarding the potential long-term effects of playing football on brain health, specifically that playing football before and during high school might cause damage to the brain that manifests years or decades later as depression or suicidality. This study examined if playing high school football was associated with increased lifetime risk for depression, suicidality over the past year, or depressed mood in the past week in men aged between their middle 30 s to early 40 s.

Methods

Publicly available data from the National Longitudinal Study of Adolescent to Adult Health were analyzed. This longitudinal, prospective cohort study sampled nationally representative U.S. youth starting in 1994–1995 (Wave I) and most recently in 2016–2018 (Wave V). A total of 3,147 boys participated in Wave I (median age = 15), of whom 1,805 were re-assessed during Wave V (median age = 38).

Results

Of the 1,762 men included in the study, 307 (17.4%) men reported being diagnosed with depression and 275 (15.6%) reported being diagnosed with an anxiety disorder or panic disorder at some point in their life. When comparing men who played high school football to those who did not, there were no differences in the proportions of the sample who had a lifetime diagnosis of depression, lifetime diagnosis of anxiety/panic disorders, suicidal ideation in the past year, psychological counseling in the past year, or current depressed mood. However, men who received psychological counseling and/or experienced suicidal ideation during adolescence were significantly more likely to report a lifetime history of depression, suicidal ideation in the past year, and current depressed mood.

Conclusion

Individuals who reported playing football during adolescence did not have an increased risk of depression or suicidal ideation when they were in their middle 30 s to early 40 s, but mental health problems during adolescence were associated with an increased risk for psychological health difficulties more than 20 years later.

Hypersensitivity to negative feedback during dynamic risky-decision making in major depressive disorder: An event-related potential study

BACKGROUND

Patients with major depressive disorder (MDD) exhibit a diminished ability to think or concentrate, indecisiveness, and altered sensitivity to reward and punishment. These impairments can influence complex risk-related decision-making in dynamic environments. The neurophysiological mechanisms mediating MDD effects on decision-making behavior are not well understood.

METHODS

Patients with MDD (N=50) and healthy controls (HC, N=40) were enrolled. They completed a series of psychometric tests. Event-related potentials (ERPs) were recorded during the performance of a well-validated modified version of Balloon Analogue Risk Task (BART).

RESULTS

BART behavior data were similar across the two groups except the MDD patients showed more stability of risk aversion. Neurophysiologically, BART losses generated larger P3 amplitudes than wins, and MDD patients had larger feedback-related negativity (FRN) components than HCs in response to negative feedback (losses). Greater FRN amplitudes in response to losses correlated with higher levels of depressiveness, psychological pain, and anhedonia. A longer FRN latency in MDD patients was associated with more severe suicidal ideation.

LIMITATIONS

The findings are based on cross-sectional data, which are not powerful enough to make causal inferences.

CONCLUSION

MDD patients exhibit enhanced FRNs in the frontocentral region after receiving negative feedback in a risky decision-making task. FRN magnitude is associated with depressive symptom severity. Punishment hypersensitivity may contribute to the maintenance of depressive symptoms in MDD patients, and FRN may be a useful index of such hypersensitivity.

"Hard to Say, Hard to Understand, Hard to Live": Possible Associations between Neurologic Language Impairments and Suicide Risk

In clinical practice, patients with language impairments often exhibit suicidal ideation (SI) and suicidal behavior (SB, covering the entire range from suicide attempts, SA, to completed suicides). However, only few studies exist regarding this subject. We conducted a mini-review on the possible associations between neurologic language impairment (on the motor, comprehension, and semantic sides) and SI/SB. Based on the literature review, we hypothesized that language impairments exacerbate psychiatric comorbidities, which, in turn, aggravate language impairments. Patients trapped in this vicious cycle can develop SI/SB. The so-called “affective prosody” provides some relevant insights concerning the interaction between the different language levels and the world of emotions. This hypothesis is illustrated in a clinical presentation, consisting of the case of a 74-year old woman who was admitted to a psychiatric emergency department (ED) after a failed SA. Having suffered an ischemic stroke two years earlier, she suffered from incomplete Broca’s aphasia and dysprosody. She also presented with generalized anxiety and depressive symptoms. We observed that her language impairments were both aggravated by the exacerbations of her anxiety and depressive symptoms. In this patient, who had deficits on the motor side, these exacerbations were triggered by her inability to express herself, her emotional status, and suffering. SI was fluctuant, and—one year after the SA—she completed suicide. Further studies are needed to ascertain possible reciprocal and interacting associations between language impairments, psychiatric comorbidities, and SI/SB. They could enable clinicians to better understand their patient’s specific suffering, as brought on by language impairment, and contribute to the refining of suicide risk detection in this sub-group of affected patients.

Suicide in Older Adult Men Is Not Related to a Personal History of Participation in Football

Introduction: It is reasonable to estimate that tens of millions of men in the United States played high school football. There is societal concern that participation in football confers risk for later-in-life mental health problems. The purpose of this study is to examine whether there is an association between a personal history of playing high school football and death by suicide. Methods: The subjects were obtained from the Lieber Institute for Brain Development (LIBD) brain donation program in collaboration with the Office of the Medical Examiner at Western Michigan University Homer Stryker MD School of Medicine. Donor history was documented via medical records, mental health records, and telephone interviews with the next-of-kin. Results: The sample included 198 men aged 50 or older (median = 65.0 years, interquartile range = 57-75). There were 34.8% who participated in contact sports during high school (including football), and 29.8% participated in high school football. Approximately one-third of the sample had suicide as their manner of death (34.8%). There was no statistically significant difference in the proportions of suicide as a manner of death among those men with a personal history of playing football compared to men who did not play football or who did not play sports (p = 0.070, Odds Ratio, OR = 0.537). Those who played football were significantly less likely to have a lifetime history of a suicide attempt (p = 0.012, OR = 0.352). Men with mood disorders (p < 0.001, OR = 10.712), substance use disorders (p < 0.020, OR = 2.075), and those with a history of suicide ideation (p < 0.001, OR = 8.038) or attempts (p < 0.001, OR = 40.634) were more likely to have suicide as a manner of death. Moreover, those men with a family history of suicide were more likely to have prior suicide attempts (p = 0.031, OR = 2.153) and to have completed suicide (p = 0.001, OR = 2.927). Discussion: Suicide was related to well-established risk factors such as a personal history of a mood disorder, substance abuse disorder, prior suicide ideation, suicide attempts, and a family history of suicide attempts. This study adds to a steadily growing body of evidence suggesting that playing high school football is not associated with increased risk for suicidality or suicide during adulthood.

Mental Pain, Psychological Distress, and Suicidal Ideation During the COVID-19 Emergency: the Moderating Role of Tolerance for Mental Pain

The psychosocial stressors related to the ongoing COVID-19 pandemic and associated lockdowns have been shown to lead to an exacerbation of suicide risk. The present study aims to examine (a) the contribution of mental pain intensity to psychological distress and suicidal ideation during the COVID-19 pandemic and (b) the protective role of mental pain tolerance in buffering these adverse mental health effects. A total of 652 adults (74.2% female, M = 33.99 years, SD = 13.74) were assessed through an online survey during the first mandatory lockdown in Italy. Participants completed measures of mental pain intensity and tolerance, psychological distress, and suicidal ideation. Results showed that mental pain intensity significantly predicted increases in psychological distress and suicidal ideation while mental pain tolerance significantly buffered the adverse effects of mental pain intensity on psychological distress and suicidal ideation. The findings highlight that tolerance for mental pain may act as a powerful protective factor during the pandemic. Evidence-based public health interventions fostering tolerance for mental pain during a pandemic are needed in order to effectively reduce suicide in potential risk groups.

Playing High School Football Is Not Associated With an Increased Risk for Suicidality in Early Adulthood

OBJECTIVE

To determine if playing high school football is associated with suicide ideation between the ages of 24 and 32 years.

DESIGN

Data were analyzed from the National Longitudinal Study of Adolescent to Adult Health. This prospective cohort study sampled nationally representative US participants at 4 time points from 1994 to 2008.

SETTING

In-home assessment.

PARTICIPANTS

There were 3147 boys (age: median = 14.9, SD = 1.8) who participated during adolescence in 1994 to 1995 (wave I), of whom 2353 were reinterviewed in 2008 (wave IV, age: median = 29.1, SD = 1.8).

ASSESSMENT OF RISK FACTORS

Football participation, history of psychological counseling, suicide ideation, and a suicide attempt in the past year during high school.

MAIN OUTCOME MEASURES

Lifetime history of depression, suicide ideation within the past year, and feeling depressed in the past 7 days at wave IV.

RESULTS

Men who played high school football, compared with those who did not, reported similar rates of lifetime diagnosis of depression, suicide ideation in the past year, and feeling depressed in the past 7 days. Those who played football reported similar rates of suicide ideation in the past year when they were in their early 20s. Individuals who underwent psychological counseling during adolescence were more likely to report a lifetime history of depression and suicide ideation in the past year.

CONCLUSIONS

Young men who played high school football are not at an increased risk for suicide ideation during both their early 20s and late 20s. By contrast, those who experienced mental health problems in high school were much more likely to experience suicide ideation during their 20s.

Highlighting psychological pain avoidance and decision-making bias as key predictors of suicide attempt in major depressive disorder-A novel investigative approach using machine learning

OBJECTIVE

Predicting suicide is notoriously difficult and complex, but a serious public health issue. An innovative approach utilizing machine learning (ML) that incorporates features of psychological mechanisms and decision-making characteristics related to suicidality could create an improved model for identifying suicide risk in patients with major depressive disorder (MDD).

METHOD

Forty-four patients with MDD and past suicide attempts (MDD_SA, N = 44); 48 patients with MDD but without past suicide attempts (MDD_NS, N = 48-42 of whom with suicide ideation [MDD_SI, N = 42]), and healthy controls (HCs, N = 51) completed seven psychometric assessments including the Three-dimensional Psychological Pain Scale (TDPPS), and one behavioral assessment, the Balloon Analogue Risk Task (BART). Descriptive statistics, group comparisons, logistic regressions, and ML were used to explore and compare the groups and generate predictors of suicidal acts.

RESULTS

MDD_SA and MDD_NS differed in TDPPS total score, pain arousal and avoidance subscale scores, suicidal ideation scores, and relevant decision-making indicators in BART. Logistic regression tests linked suicide attempts to psychological pain avoidance and a risk decision-making indicator. The resultant key ML model distinguished MDD_SA/MDD_NS with 88.2% accuracy. The model could also distinguish MDD_SA/MDD_SI with 81.25% accuracy. The ML model using hopelessness could classify MDD_SI/HC with 94.4% accuracy.

CONCLUSION

ML analyses showed that motivation to avoid intolerable psychological pain, coupled with impaired decision-making bias toward under-valuing life's worth are highly predictive of suicide attempts. Analyses also demonstrated that suicidal ideation and attempts differed in potential mechanisms, as suicidal ideation was more related to hopelessness. ML algorithms show useful promises as a predictive instrument.

Mental Pain in Eating Disorders: An Exploratory Controlled Study

Mental pain (MP) is a transdiagnostic feature characterized by depression, suicidal ideation, emotion dysregulation, and associated with worse levels of distress. The study explores the presence and the discriminating role of MP in EDs in detecting patients with higher depressive and ED-related symptoms. Seventy-one ED patients and 90 matched controls completed a Clinical Assessment Scale for MP (CASMP) and the Mental Pain Questionnaire (MPQ). ED patients also completed the Beck Depression Inventory-II (BDI-II), Clinical Interview for Depression (CID-20), and Eating Attitudes Test (EAT-40). ED patients exhibited significantly greater severity and higher number of cases of MP than controls. Moreover, MP resulted the most important cluster predictor followed by BDI-II, CID-20, and EAT-40 in discriminating between patients with different ED and depression severity in a two-step cluster analysis encompassing 87.3% (n = 62) of the total ED sample. Significant positive associations have been found between MP and bulimic symptoms, cognitive and somatic-affective depressive symptoms, suicidal tendencies, and anxiety-related symptoms. In particular, those presenting MP reported significantly higher levels of depressive and anxiety-related symptoms than those without. MP represents a clinical aspect that can help to detect more severe cases of EDs and to better understand the complex interplay between ED and mood symptomatology.

Exposure to suicide in the family and suicidal ideation in Portugal during the Covid-19 pandemic: The mediating role of unbearable psychache

Objectives

This study tested the mediation effects of two facets of psychache – bearable and unbearable – in the relationship between exposure to suicide in the family and suicidal ideation in Portugal during the Covid‐19 pandemic.

Methods

Two hundred and forty‐four adults aged between 19 and 64 participated. Two groups were defined: one exposed to suicide in the family (n = 42) and a control group (n = 192).

Results

Path analysis using structural equation modelling tested a mediation model. Results demonstrated that unbearable psychache fully mediated the relationship between exposure to suicide and suicidal ideation, even when controlling for the mediation effects of depressive symptoms, the presence of a psychiatric diagnosis, and years of education.

Conclusions

These results suggest that rather than considering just the global experience of psychache in individuals exposed to suicide, researchers and clinicians should look to the presence of unbearable psychache given its contribution to suicidal ideation.

Practitioner points

Unbearable psychache fully mediated the relationship between exposure to suicide in the family and suicidal ideation

It is not the global experience of psychache that contributes to suicide ideation in individuals exposed to suicide in the family rather the presence of unbearable psychache

Functional alterations of the suicidal brain: a coordinate-based meta-analysis of functional imaging studies

Altered brain activities in suicidal subjects have been reported in a number of neuroimaging studies. However, the activity aberrances were inconsistent in previous investigations. Thus, we aimed to address activity abnormalities in suicidal individuals. Databases were searched to perform a meta-analysis of whole-brain functional MRI studies of suicidal individuals through January 14, 2020. Meta-analyses were conducted using Seed-based d Mapping software. Based on a meta-analysis of 17 studies comprising 381 suicidal individuals and 642 controls, we mainly found that increased activity in the bilateral superior temporal gyrus, left middle temporal gyrus, and bilateral middle occipital gyrus, along with decreased activity in the right putamen and left insula, were detected in suicidal individuals compared with nonsuicidal subjects. To reduce methodological heterogeneity between the included studies, subanalyses of behavioral domains were conducted, and the right superior temporal gyrus was found to increase in all subanalyses of domains. In subanalyses of suicidal attempters and ideators, suicide attempters displayed hyperactivation in the bilateral superior temporal gyrus and left middle temporal gyrus and blunted responses in the left insula relative to controls. Suicidal ideators demonstrated elevated activation in the right middle occipital gyrus and reduced activity in the right putamen relative to controls. The bilateral superior temporal gyrus was the most robust finding, replicable in all data sets in the jackknife sensitive analysis. Moreover, increased activity in the right superior temporal gyrus, left middle temporal gyrus, and right middle occipital gyrus was found to be involved with higher suicide ideation scores. This study revealed several brain regions associated with suicidality. These findings may contribute to our understanding of the pathophysiology of suicide and have important implications for suicide prevention and interventions.

Association of mental disorders with firearm suicides: A systematic review with meta-analyses of observational studies in the United States

In the United States (US), 61% of all suicide cases may involve firearms, and some evidence suggests that mental disorders may play a role in suicide by firearm. We performed the first systematic review and meta-analyses to investigate: (i) whether mental disorders are associated with suicide by firearm, and (ii) whether the risk of using a firearm compared with alternative means is associated with higher levels of suicide in individuals with a mental disorder METHODS AND FINDINGS: We searched twelve databases from inception to the 24th of May 2020. We retrieved 22 observational studies conducted in the US. Random-effects meta-analyses showed individuals who had a diagnosis of a mental disorder had lower odds (odds ratios (OR)= 0.50, 95% CI: 0.36 to 0.69; I²=100 (95% CI: 87 to 100%), of dying by suicide with a firearm than those who did not have a diagnosis of a mental disorder. Secondary analysis showed that decedents who had a mental health diagnosis resulted in lower odds of dying by suicide by using firearms than using other means LIMITATIONS: Risk of bias revealed a heterogeneous and poor definition of mental disorders as well as lack of control for potential demographic confounding factors. In the meta-analyses, studies were combined in the same analytic sample as 77% of these studies did not specify the type of mental disorder CONCLUSION: While our results seem to suggest that having a mental disorder may not be consistently associated with the odds of dying by suicide using a firearm, the presence of substantial heterogeneity and high risk of bias precludes any firm conclusions.

From motivation, decision-making to action: An fMRI study on suicidal behavior in patients with major depressive disorder

OBJECTIVE

We explored the neural mechanisms underlying disadvantageous risk decision making in un-medicated major depressive disorder patients who had recent suicide attempts.

METHODS

53 patients with major depressive disorder (MDD), including 23 with a history of suicide attempts (SA) and 30 without (NS), and 30 healthy controls (HCs) completed pertinent psychometric assessments, and the dynamic decision making balloon analogue risk task (BART) under fMRI. We also built a 4-parameter Bayesian computational modeling for decision making analyses.

RESULTS

Several distinct findings emerged. First, SA patients had no depression intensity difference but higher pain avoidance in psychometrics, and more risk aversion in the BART when compared to the NS patients, with computational modeling confirming such reduced risk-taking propensity. Second, SA patients showed smaller left insular cortex activation than NS patients during the high risk, decisional phase of BART, and the modulation correlated with pain avoidance in both SA and NS groups. Third, during feedback phase of loss trials of the BART, SA patients had greater activation in the left dorsolateral prefrontal cortex (dlPFC) than NS patients.

CONCLUSION

Taken together, we present novel findings and propose interpretations that the differential insula activation likely relates to high uncertainty-aversion in SA patients, contrary to the typical view that they are impulsive and risk prone. The differential left dlPFC activation likely suggests hypersensitivity to loss, contributing to conservative decision-making at large, and extreme choices such as suicide when value estimations are compromised and emotionally overwhelmed. The interactive interpretation places a renewed focus on psychological pain avoidance as a robust motivator for suicidal behavior.

Assessment of Psychological Pain in Clinical and Non-Clinical Samples: A Preliminary Investigation Using the Psychic Pain Scale

Psychological pain is an important contributing factor to suicide risk. The present study examined the psychometric properties of the Psychic Pain Scale (PPS), a new measure assessing unbearable negative affect as described in Maltsberger's theory of suicidality. The PPS was administered to n = 131 adult psychiatric patients as well as n = 953 undergraduate students. An initial factor analysis which replicated across both clinical and undergraduate samples identified two factors, affective deluge, and loss of control. These subscales were associated with risk factors including trauma history, severity of psychopathology, and decreased resilience, as well as a range of pathological personality traits. Findings support the utility of the PPS as a measure of psychological pain and point to future directions of empirical evaluation.

Neurophysiological Markers Related to Negative Self-referential Processing Differentiate Adolescent Suicide Ideators and Attempters

Background

Adolescent suicide is a major public health concern, and presently, there is a limited understanding of the neurophysiological correlates of suicidal behaviors. Cognitive models of suicide indicate that negative views of the self are related to suicidal thoughts and behaviors, and this study investigated whether behavioral and neural correlates of self-referential processing differentiate suicide ideators from recent attempters.

Methods

Adolescents with depression reporting current suicidal ideation and no lifetime suicide attempts (suicide ideators, n = 30) and past-year suicide attempts (recent attempters, n = 26) completed a self-referential encoding task while high-density electroencephalogram data were recorded. Behavioral analyses focused on negative processing bias (i.e., tendency to attribute negative information as being self-relevant) and drift rate (i.e., slope of reaction time and response type that corresponds to how quickly information is accumulated to make a decision about whether words are self-referent). Neurophysiological markers probing components reflecting early semantic monitoring (P2), engagement (early late positive potential), and effortful encoding (late late positive potential) also were tested.

Results

Adolescent suicide ideators and recent suicide attempters reported comparable symptom severity, suicide ideation, and mental disorders. Although there were no behavioral differences, compared with suicide ideators, suicide attempters exhibited greater P2 amplitudes for negative versus positive words, which may reflect enhanced attention and arousal in response to negative self-referential stimuli. There were no group differences for the early or late late positive potential.

Conclusions

Enhanced sensory arousal in response to negative stimuli-that is, attentional orienting to semantic, emotional, and self-relevant features-differentiates adolescent suicide attempters from ideators and thus may signal risk for suicidal behavior.

The Development of a Multidimensional Inventory for the Assessment of Mental Pain (FESSTE 30)

Background: Although the term "mental pain" is often the subject of expert opinions regarding claims for damages, there is still no standardized questionnaire in the German-speaking area to operationalize this concept. Therefore, the aim of this work is the development and validation of a self-assessment measurement for psychological pain after traumatic events (FESSTE). Methods: A first version of the questionnaire was applied on a sample of the German speaking general population (N = 425; 88% female). After performing an item analysis and exploratory factor analysis, the questionnaire was shortened and tested on a second German speaking general population sample (N = 619; 89% female). Finally, the newly developed questionnaire was related to the extent of traumatization (measured with a uniquely designed trauma checklist attached to the FESSTE) and already established instruments for the assessment of psychiatric symptom burden, which included the Brief Symptom Inventory-18 (BSI-18) and the Post-traumatic-Stress-Scale (PTSS-10). Results: The final version of the FESSTE consists of a total of 30 items and covers the subscales "Somatization," "Depression," "Intrusive Memories," "Dissociation" and "Anxiety," and a total scale "Mental Pain." Based on the confirmatory factor analysis, it is assumed that the latent factor structure of the FESSTE can be best described as a bifactor-model. The final version shows a satisfactory model fit, high internal consistencies, and strong positive correlations with the BSI-18 and PTSS-10, as well as the extent of traumatic experiences. Discussion: The FESSTE enables an operationalization of mental pain comprising five subscales and one total scale. What is more, the trauma checklist attached to the FESSTE allows for the standardized assessment of potentially traumatic experiences and the corresponding extent of these experiences. The results indicate that the FESSTE is a reliable and valid self-assessment procedure for mental pain, which is suitable for use in research and in expert practice.

Ambient Discrimination, Victimization, and Suicidality in a Non-Probability U.S. Sample of LGBTQ Adults

Individuals who identify as lesbian, gay, bisexual, transgender, or queer (LGBTQ) are at a higher risk for suicidality compared to the general population. A growing body of research has investigated this risk, particularly with attention to systemic factors such as discrimination and harassment. Unfortunately, research has only examined the impact of direct discrimination on suicidality and has neglected to examine how ambient discrimination (i.e., witnessing or being made aware of discriminatory behaviors directed at someone other than yourself in your group) relates to suicidality. Additionally, although some links exist between discrimination and suicidality, the mechanisms by which these are related are understudied. This study aimed to address these gaps by exploring the effect of ambient discrimination on suicidal ideation and examining psychological pain as a mediator in this relationship. Data were collected from a sample of 200 LGBTQ-identified individuals (M age = 35 years; 53.5% female; 86% White). Results of independent t tests and a one-way multivariate ANOVA revealed greater vulnerability for ambient/direct discrimination and psychache among individuals identifying as transgender, queer, and other. Regression and mediation analyses revealed that while both ambient and direct discrimination predicted suicidal ideation, only direct discrimination accounted for unique variance in the outcome; however, both ambient and direct discrimination contributed unique variance to psychological pain, which fully mediated their relationships to suicidal ideation. Results of this study may begin to provide insight into the pathways of risk and points of intervention for suicidality in the LGBTQ community.
