A systematic review of the relationship between rumination and suicidality

Effects of defeat and entrapment on suicide risk in university population: the role of rumination and sex

Background

Suicide is recognized as a significant public health issue, with adolescents/young people being a risk group of concern. Taking the integrated motivational-volitional model as a reference, this study focuses on analyzing the association between defeat and entrapment, on the one hand, and suicide risk, on the other, in a university population without depressive symptoms, while also considering the role of rumination and sex.

Method

The survey study involved a community sample of 650 Spanish university students. A total of 524 students (150 men (Mage = 20.6, SD = 3.7) and 374 women (Mage = 20.4, SD = 3.6)) completed self-report measures of suicide risk, defeat, entrapment, and rumination.

Results

Defeat and entrapment were significantly associated with suicide risk, and higher rumination was both directly and indirectly associated with higher levels of entrapment through the variable of defeat. However, the effect of rumination on entrapment varied by sex.

Conclusion

Despite being a cross-sectional preliminary study, this work identifies important variables in the trajectory of suicidal ideation. Adolescence and young adulthood are a critical stage for intervening to reduce the risk of death by suicide, and this study provides findings that may inform preventive approaches.

Risk and Protective Effects of Need for Approval on Self-Injury in Adolescent Girls

The goal of this research was to expand theoretical models of adolescent suicide by exploring whether individual differences in adolescent girls' need for approval (NFAavoid and NFAapproach) contribute to risk for, or protection against, self-injurious thoughts and behaviors (SITBs). We examined these novel hypotheses in a series of concurrent and longitudinal analyses in two samples of adolescent girls (Study 1: N = 89, Mage = 16.31 years, SD = 0.84, 67.4% White; Study 2: N = 229, Mage = 11.80, SD = 1.80, 49.8% White). Hierarchical linear and logistic regressions revealed that NFAavoid was generally associated with higher risk for SITBs, whereas NFAapproach generally had a protective effect against SITBs; moreover, the strength of these associations depended on the extent to which girls engaged in rumination. Together, these results suggest that encouraging girls to develop diverse foundations for their sense of self-worth beyond peer judgements may protect against SITBs.

Repetitive negative thinking and suicidal ideation in internalizing psychopathologies: A replication study

Suicidal ideation (SI), a risk factor for suicide, is prevalent in internalizing psychopathologies, including depression and anxiety. Rumination and worry are well-studied repetitive negative thinking (RNT) constructs implicated in internalizing psychopathologies. These constructs have shared and distinct characteristics. However, the relationship between rumination and worry and their associations with SI are not fully understood in clinical samples. The present study used correlational and regression analysis to evaluate these relationships as a secondary data analysis in treatment-seeking participants with internalizing psychopathologies in two independent samples (Study 1:n = 143; Study 2:n = 133). Results showed about half of the participants endorsed SI (Study 1:n = 79; Study 2:n = 71). Correlations revealed a significant, positive relationship between rumination and worry. Regression results with SI as the dependent variable showed rumination significantly positively corresponded with SI in both studies. Post-hoc partial correlations controlling for symptom severity (depression, anxiety), worry, and age showed the rumination-SI relationship was maintained in both studies. Findings for worry and SI were inconsistent between studies. Findings indicate rumination, but not worry, could be a stable, unique contributor to SI in internalizing psychopathologies. It may be useful to incorporate RNT into suicide risk assessment for individuals with internalizing conditions.

Mindfulness-Based Cognitive Therapy for Individuals Who Are Suicidal: A Randomized Controlled Trial

There is a need for well-described treatments targeting individuals at risk for suicidal behaviors. The present study aims to investigate the effectiveness of MBCT adapted to individuals who are suicidal (MBCT-S) in a randomized controlled trial, comparing an intervention group receiving MBCT-S and treatment as usual (TAU) with a control group receiving TAU only. Participants who were 18 years or older and experienced suicidal ideation were included. Assessments on suicidal ideation and symptoms associated with suicidal behavior were carried out at baseline, post-treatment, and 12 weeks after the end of the training. When comparing the intervention group with the control group, a significant reduction was found at follow-up in suicidal ideation and depressive symptoms. When focusing on the intervention group only, a significant reduction was found in suicidal ideation, depressive symptoms, hopelessness, worrying, defeat, and entrapment, and a significant increase in mindfulness both at post-treatment and at follow-up. The findings suggest that MBCT-S is a promising suicide-specific intervention as it may have the potential to reduce suicidal ideation and suicide-related components.

Assessing a Suicide Prevention Helpline's Impact on Caller Crisis Level and Suicidality

OBJECTIVE

Worldwide helplines are considered an important part of suicide prevention strategies. Nevertheless, evidence regarding the impact of suicide prevention helplines on the suicidality of its users remains limited and is frequently confronted with methodological issues. This study aimed to assess the impact of crisis calls on callers' levels of crisis and suicidality both immediately after the call and at follow-up compared to before the call. After the call, the satisfaction of the callers with the intervention was also assessed.

METHODS

A pre-post study, generated automatically by a telephone system, was conducted in order to compare the level of crisis and suicidality (operationalized by five indicators: hopelessness, entrapment, controllability, suicidal intent, and social support) experienced by callers before and immediately after the call and at follow-up (one to two weeks after the call).

RESULTS

Callers (n = 487) showed significant improvement in their level of crisis (p < .001, d = -0.31), hopelessness (p < .001, d = -0.22), entrapment (p < .001, d = -0.25), suicide intent (p < .001, d = -0.37), and social support (p < .001, d = 0.33) after the call compared to before the call. Improvements were also found at follow-up compared to pretest. The satisfaction of callers with the helpline was high.

CONCLUSIONS

This study adds to the growing evidence on suicide prevention helplines and addresses some important methodological issues in helpline research. Furthermore, it shows promising results regarding the potential supportive impact of helplines on callers who feel suicidal.

Major Depressive Disorder with Catatonia: A Phenotype Related to Autistic Traits and High Suicidality

Background: Major Depressive Disorder (MDD) represents a significant global health concern, often complicated by comorbidities such as catatonia and autism spectrum disorder (ASD). Recognizing the interplay among these conditions and their impact on suicidal tendencies is crucial for effective clinical management. Methods: A total sample of 147 subjects with MDD was divided into Significant Catatonia (SC) and Non-Significant Catatonia (NSC) groups based on Catatonia Spectrum (CS) scores. Participants were evaluated through the Structured Clinical Interview for DSM-5, Research Version (SCID-5-RV), the Adult Autism Subtreshold Spectrum (AdAS Spectrum), and the Mood Spectrum-Self Report questionnaires. Statistical analyses included Mann-Whitney U test, Chi-square test, logistic regression analyses, and a decision tree model. Results: The SC group exhibited higher CS, AdAS Spectrum, and MOODS-SR total and domain scores compared to the NSC group. Individuals with significant autistic traits were over-represented in the SC group, as well as participants with higher suicidality, suicidal ideation, and a history of suicide attempts. The total AdAS Spectrum and MOOD-SR score, the AdAS domain "Hyper-hypo reactivity to sensory input", and the "Cognitive depressive" MOOD-SR domain were predictive of belonging to the SC group. Suicidality levels appeared to be higher in clinically significant ASD, intermediate in subjects with autistic traits (AT), and low in the absence of AT. Conclusions: the study suggests the existence of a specific phenotype of MDD associated with catatonia, characterized by elevated autistic traits and suicide risk.

The Dream Experience and Its Relationship with Morning Mood in Adolescents Hospitalized after a Suicide Attempt

Suicidality in adolescents has been associated with emotional distress, stressful life events, relationship issues, and nightmares to name a few. This study explored the actual dream content and the mood at pre-sleep, during a reported dream, and in the morning in 33 adolescents admitted to the hospital on account of a suicide attempt. In all aspects, hospitalized adolescents were compared to 33 matched adolescents who had followed the same protocol. In accordance with the Continuity and the Threat Simulation theories of dream formation, it was hypothesized that the waking-life experiences of suicidal adolescents would transpire in both dream mood and content as well as in the frequency of nightmares. Dreams were analyzed by independent judges using traditional dream content scales, including for the presence of negative and destructive themes and types of interpersonal relationships. As predicted, more suicidal adolescents experienced frequent nightmares, which was significant. A higher negative mood at pre-sleep, within dreams, and at post-sleep was also observed. Furthermore, their dreams contained a higher prevalence of destructive themes and failures, as well as self-directed and death-resulting aggressions. Regression analyses indicated that morning mood was most accurately predicted by positive and negative dream mood in the normative adolescents, whereas only negative dream mood appeared to predict subsequent waking affect in suicidal participants. Our results underline the valuable potential of implementing nightmare-reducing therapies in the presence of suicidal adolescents who suffer from frequent nightmares.

The role of Theory of Mind in the transition towards suicidal attempts in youth NSSI: an exploratory pilot study

Non-suicidal self-injury (NSSI) can both precede and co-occur with suicidal attempts (SA). Underlying mechanisms/factors leading to the transition to SA in NSSI youths have been proposed (including the role of social cognition), despite they should be yet confirmed. Therefore, the study aims at exploring the role of the Theory of Mind in the differentiation of a sample of NSSI youngsters (aged 15-24) according to the presence of SA. We divided the sample into 4 groups using the Deliberate Self Harm Inventory (DSHI) and Columbia Suicide Severity Rating Scale (C-SSRS): control group (notNSSInotSA), NSSI without SA (NSSInotSA), NSSI with SA (NSSIplusSA), and SA without NSSI (SAonly). NSSIplusSA patients displayed higher Reading the Mind in the Eyes Test (RMET) scores (indicative of ToM abilities) than both the NSSInotSA (p=0.0016) and SAonly groups (p=0.0198), while SAonly patients showed lower RMET scores compared to the control group (p=0.0214). Multiple regression models used to differentiate NSSInotSA and NSSIplusSA found a significant association between RMET and LOSCS-CSC (Level Of Self-Criticism Scale-Comparative Self-Criticism) (pC=0.0802, pD=0.0016, pG=0.0053). Our findings supported the hypothesis that a hypertrophic affective ToM may possibly be associated with the occurrence of SA in youth NSSI. Further larger and longitudinal studies should confirm these preliminary findings, by exploring all social cognition dimensions.

Multiple paths to rumination within a network analytical framework

Theories of rumination have proposed different psychological factors to place one at risk for repetitive negative thinking. A comprehensive empirical test that captures the most relevant contributors to rumination is lacking. Building on influential self-regulatory and metacognitive frameworks, we modeled how key constructs in this context relate to ruminative thinking. 498 participants completed online questionnaires including indicators of rumination, metacognition, promotion goal orientation, effortful control, and depression. We estimated regularized partial correlation networks to investigate unique associations between the different constructs and followed these analyses up with directed acyclic graphs to identify potential pathways towards rumination. Results demonstrated that: (1) both self-regulatory and metacognitive factors were directly linked to rumination, amongst these were (2) positive beliefs, negative beliefs about uncontrollability and harm, cognitive self-consciousness, depression, effortful control, perfectionism, and (lack of) cognitive confidence, and (3) we identified multiple directed pathways, suggesting three direct contributors to rumination while controlling for the influence of all other variables: diminished effortful control, positive beliefs, and cognitive self-consciousness. This study is the first to comprehensively assess metacognitive and self-regulatory frameworks of rumination in a data-driven manner. Our findings suggest that there are multiple pathways towards rumination, which should be incorporated in clinical case conceptualization of rumination and related disorders.

Repetitive negative thinking as a unique transdiagnostic risk factor for suicidal ideation

Repetitive negative thinking (RNT) is a transdiagnostic symptom observed across mood and anxiety disorders and is characterized by frequent, distressing thoughts that are perceived as uncontrollable. Specific forms of RNT have been linked to increased suicide risk. However, most work examining links between RNT and suicide has been conducted within specific disorders and subtypes of RNT (e.g., rumination in individuals with depression). The present study aimed to investigate associations between transdiagnostic RNT and suicidal ideation. We hypothesized RNT would be associated with suicide risk beyond disorder-specific clinical symptoms. Fifty-four participants with mood, anxiety, and/or traumatic stress disorders completed an interview assessing suicidal risk (Columbia-Suicide Severity Rating Scale (C-SSRS)) and self-report questionnaires assessing transdiagnostic RNT, depression, and anxiety. Based on C-SSRS, we divided participants into high or low suicide risk groups. We analyzed the relationship between suicidal risk group and RNT and found that RNT was uniquely associated with suicidal risk group, controlling for depression and anxiety severity. Our results suggest including assessments of RNT may have clinical utility for understanding the degree of suicide risk in individuals and point to the potential utility of including clinical interventions to target this symptom for those at high risk of suicide.

Suicidal ideation in female individuals with fibromyalgia and comorbid obesity: prevalence and association with clinical, pain-related, and psychological factors

OBJECTIVE

Individuals with fibromyalgia report alarming levels of suicidal ideation, and comorbidity with other chronic health conditions such as obesity-a risk factor for suicidal ideation per se-could further complicate the clinical picture. The aim of this study is to determine, in a sample of women with fibromyalgia and comorbid obesity, the prevalence of suicidal ideation and to evaluate clinical, pain-related and psychological factors associated with suicidal ideation.

METHODS

In total, 156 female individuals with fibromyalgia and obesity were recruited and completed a series of self-report measures that assessed (i) the level of pain intensity, (ii) depressive symptomatology, (iii) sleep quality, and (iv) pain catastrophizing. Suicidal ideation was evaluated by item #9 of the Beck Depression Inventory. In addition, information regarding previous suicide attempts and current opioid use was collected.

RESULTS

3n sum, 7.8% of participants reported presence of suicidal ideation. According to the results of the multiple logistic regression, depressive symptomatology, sleep quality, and pain catastrophizing were associated with the presence of suicidal ideation.

DISCUSSION

The presence of suicidal ideation in our sample was significantly associated with depressive symptomatology, sleep quality, and pain catastrophizing. Our findings are the first to suggest a unique (ie, independent of depressive symptomatology, and sleep quality) association between pain catastrophizing and suicidal ideation in the context of fibromyalgia and comorbid obesity. In order to prevent and reduce suicidal ideation, these factors should be assessed and targeted in interventions for pain management. Future research should investigate the extent to which addressing depressive symptoms, sleep quality, and pain catastrophizing reduces suicidal ideation.

Mapping Neurophysiological Subtypes of Major Depressive Disorder Using Normative Models of the Functional Connectome

BACKGROUND

Major depressive disorder (MDD) is a highly heterogeneous disorder that typically emerges in adolescence and can occur throughout adulthood. Studies aimed at quantitatively uncovering the heterogeneity of individual functional connectome abnormalities in MDD and identifying reproducibly distinct neurophysiological MDD subtypes across the lifespan, which could provide promising insights for precise diagnosis and treatment prediction, are still lacking.

METHODS

Leveraging resting-state functional magnetic resonance imaging data from 1148 patients with MDD and 1079 healthy control participants (ages 11-93), we conducted the largest multisite analysis to date for neurophysiological MDD subtyping. First, we characterized typical lifespan trajectories of functional connectivity strength based on the normative model and quantitatively mapped the heterogeneous individual deviations among patients with MDD. Then, we identified neurobiological MDD subtypes using an unsupervised clustering algorithm and evaluated intersite reproducibility. Finally, we validated the subtype differences in baseline clinical variables and longitudinal treatment predictive capacity.

RESULTS

Our findings indicated great intersubject heterogeneity in the spatial distribution and severity of functional connectome deviations among patients with MDD, which inspired the identification of 2 reproducible neurophysiological subtypes. Subtype 1 showed severe deviations, with positive deviations in the default mode, limbic, and subcortical areas and negative deviations in the sensorimotor and attention areas. Subtype 2 showed a moderate but converse deviation pattern. More importantly, subtype differences were observed in depressive item scores and the predictive ability of baseline deviations for antidepressant treatment outcomes.

CONCLUSIONS

These findings shed light on our understanding of different neurobiological mechanisms underlying the clinical heterogeneity of MDD and are essential for developing personalized treatments for this disorder.

"It's a feeling of complete disconnection": experiences of existential loneliness from youth to older adulthood

BACKGROUND

Existential loneliness is a feeling which stems from a sense of fundamental separation from others and the world. Although commonly mentioned in the loneliness literature, there is relatively little empirical work on this construct, and existing work tends to focus on older and seriously ill individuals. The present study aimed to understand how people experience existential loneliness without specific constraints on precipitating factors like illness or age.

METHODS

A qualitative online survey collected data from 225 adults aged 16 to 72 years old. Participants were asked to write about their experiences of existential loneliness and how these experiences compared to non-existential loneliness. Data were analysed using reflexive thematic analysis.

RESULTS

Of 225 participants, 51% knew the meaning of "existential loneliness" upon accessing the survey and in total, 83% had experienced existential loneliness. 93% of these participants had also experienced loneliness that was not existential in nature. 175 participants provided qualitative data regarding their experiences of existential loneliness, from which four themes were identified: Existential loneliness is (1) A deeper form of loneliness, and (2) A feeling of deep disconnection, in which (3) Cognitive evaluations and negative emotions are central elements, and (4) Stress and mental health issues are perceived as relevant factors.

CONCLUSIONS

Existential loneliness is a deeply rooted and impactful form of loneliness which involves feelings of profound separateness. This aspect of loneliness is deserving of further attention. Future research directions are suggested.

Understanding the Broader Impact of Stuttering: Suicidal Ideation

PURPOSE

Suicide and suicidal ideation are topics that have a long but limited history in stuttering research. Clinicians and clinical researchers have discussed personal and therapeutic experiences with clients who have attempted suicide, died by suicide, or struggled with suicidal thoughts. This study sought to (a) explore the occurrence of suicidal ideation in a sample of adults who stutter; (b) evaluate the relationship between adverse impact related to stuttering and suicidal ideation; and (c) document respondents' thoughts related to suicide, stuttering, and their intersection.

METHOD

One hundred forty adults who stutter completed the Suicide Behavior Questionnaire-Revised (SBQ-R). Of these, 70 participants completed the Perseverative Thinking Questionnaire (PTQ), and 67 completed the Overall Assessment of the Speaker's Experience of Stuttering (OASES). Participants who indicated at least some tendency for suicidal thoughts on the SBQ-R (n = 95) were then asked a set of follow-up questions to explore their experiences of suicidal ideation related to stuttering.

RESULTS

Quantitative data indicated that the majority of adults who reported experiencing suicidal ideation associated these experiences with stuttering (61.2%, n = 59). Individuals with higher Total Scores on the PTQ and OASES were predicted to experience significantly higher rates of suicidal ideation and, in particular, a higher likelihood of having more frequent suicidal ideation in the past year. Qualitative analyses revealed that suicidal ideation intersects meaningfully with the experience of stuttering.

CONCLUSIONS

Data from this study highlight the importance of considering broader life consequences of stuttering that some adults may experience, including suicidal ideation. By being cognizant that clients may develop such thoughts, speech-language pathologists can play a valuable role in identifying and providing necessary support for at-risk individuals.

Help-seeking preferences in Australian mental health website visitors: A latent profile analysis

OBJECTIVE

Psychological distress and suicide rates are climbing in Australia despite substantial mental health programme investment in recent decades. Understanding where individuals prefer to seek support in the event of a personal or emotional crisis may help target mental health resources to where they are most needed. This study aimed to explore individual differences in help-seeking preferences that may be leveraged for early intervention and mental health service design.

METHOD

Latent profile analysis was used to explore the help-seeking preferences of 1561 Australian online help-seekers who elected to complete a psychological distress screening on a popular mental health website, Beyond Blue.

RESULTS

Four latent profiles of help-seeker emerged that illustrate distinct preference channels for support: help-negaters, professional help-seekers, family help-seekers and help-affirmatives. Help-negaters were the least likely to consider seeking help from any source, recorded the highest levels of psychological distress and suicidal ideation, and were more likely to be younger. Help-affirmatives were the most likely to seek help from any source, particularly from religious leaders, and were more likely to speak a language other than English at home.

CONCLUSION

Many individuals experiencing mental health concerns will prefer to seek support from family or community contacts rather than professionals, and some will not seek help at all. Diversity in help-seeking preferences should be considered when designing mental health services, outreach and psychoeducation materials.

Future-oriented repetitive thought, depressive symptoms, and suicide ideation severity: Role of future-event fluency and depressive predictive certainty

BACKGROUND

Knowing how future-oriented repetitive thought - i.e., repeated consideration of whether positive or negative outcomes will happen in one's future - leads to hopelessness-related cognitions may elucidate the role of anticipating the future in depressive symptoms and suicide ideation. This study examined future-event fluency and depressive predictive certainty - i.e., the tendency to make pessimistic future-event predictions with certainty - as mechanisms explaining the relation between future-oriented repetitive thought, depressive symptoms, and suicide ideation.

METHODS

Young adults (N = 354), oversampled for suicide ideation or attempt history, completed baseline measures of pessimistic future-oriented repetitive thought (i.e., the degree to which people consider whether negative outcomes will happen or positive outcomes will not happen in their futures), future-event fluency, depressive predictive certainty, depressive symptoms, and suicide ideation severity and were followed up 6 months later (N = 324).

RESULTS

Pessimistic future-oriented repetitive thought predicted depressive predictive certainty at 6-months, partially mediated by lower positive but not increased negative future-event fluency. There was an indirect relationship between pessimistic future-oriented repetitive thought and 6-month suicide ideation severity via 6-month depressive predictive certainty through 6-month depressive symptoms, and also via 6-month depressive symptoms (but not depressive predictive certainty) alone.

LIMITATIONS

Lack of an experimental design limits inferences about causality, and a predominantly female sample may limit generalizability by sex.

CONCLUSION

Clinical interventions should address pessimistic future-oriented repetitive thought - and its impact on how easily people can think about positive future outcomes - as one potential way to reduce depressive symptoms and, indirectly, suicide ideation.

Moderating roles of grit and locus of control on rumination and suicidality

Cognitive factors constitute an important risk factor to the development of suicidal thoughts and behaviors (STBs). Engaging in depressive and anger rumination are uniquely associated with elevated vulnerabilities to STBs. Variations in attentional focus and control may further modify the impacts of rumination. For one, grit resembles the inflexible thinking patterns inherent in rumination, potentially contributing to one's capability of persisting in carrying out suicidal behaviors despite fears of pain or death. In the context of rumination, locus of control may alter the perspectives to which individuals attribute negative experiences. The current study examines the moderating roles of grit and locus of control on the impact of depressive and anger rumination on suicidality. Participants (N = 322) completed a battery of self-report questionnaires measuring depressive rumination, anger rumination, grit, locus of control, and suicidal history (a history of suicidal ideation, history of suicidal attempts, or neither). Using hierarchical multinomial logistic regression in R, results revealed that, as opposed to working together, the proposed variables are more independently informative in distinguishing those with a history of suicidal ideation, suicidal attempts, or neither. Findings provide unique contribution to the suicide literature pertaining to how individuals may perceive of their own internal locus of control and grit following suicidal thoughts and beliefs. Clinical implications and future directions are provided as recommendations in line with current findings.

Development of an mHealth App-Based Intervention for Depressive Rumination (RuminAid): Mixed Methods Focus Group Evaluation

BACKGROUND

Depression is a common mental health condition that poses a significant public health burden. Effective treatments for depression exist; however, access to evidence-based care remains limited. Mobile health (mHealth) apps offer an avenue for improving access. However, few mHealth apps are informed by evidence-based treatments and even fewer are empirically evaluated before dissemination. To address this gap, we developed RuminAid, an mHealth app that uses evidence-based treatment components to reduce depression by targeting a single key depressogenic process-rumination.

OBJECTIVE

The primary objective of this study was to collect qualitative and quantitative feedback that could be used to improve the design of RuminAid before the software development phase.

METHODS

We reviewed empirically supported interventions for depression and rumination and used the key aspects of each to create a storyboard version of RuminAid. We distributed an audio-guided presentation of the RuminAid storyboard to 22 individuals for viewing and solicited user feedback on app content, design, and perceived functionality across 7 focus group sessions.

RESULTS

The consumer-rated quality of the storyboard version of RuminAid was in the acceptable to good range. Indeed, most participants reported that they thought RuminAid would be an engaging, functional, and informational app. Likewise, they endorsed overwhelming positive beliefs about the perceived impact of RuminAid; specifically, 96% (21/22) believed that RuminAid will help depressed ruminators with depression and rumination. Nevertheless, the results highlighted the need for improved app aesthetics (eg, a more appealing color scheme and modern design).

CONCLUSIONS

Focus group members reported that the quality of information was quite good and had the potential to help adults who struggle with depression and rumination but expressed concern that poor aesthetics would interfere with users' desire to continue using the app. To address these comments, we hired a graphic designer and redesigned each screen to improve visual appeal. We also removed time gating from the app based on participant feedback and findings from related research. These changes helped elevate RuminAid and informed its initial software build for a pilot trial that focused on evaluating its feasibility and acceptability.

The Relationship between Depressive Symptoms, Rumination, and Suicide Ideation in Patients with Depression

The relationship between suicide and rumination in depression is a recent topic of attention in mental health. The purpose of this study was to investigate the relationship between demographic variables, depressive symptoms, rumination, and suicide ideation in patients with depression, as well as the predictors of suicide ideation.

RESEARCH DESIGN

A cross-sectional study of 95 subjects with depression recruited intentionally from the psychiatric ward of Tzu Chi Hospital. The questionnaire included demographic data, the Beck Depression Inventory-II, the Ruminative Response Scale, and the Beck Scale for Suicide Ideation. Independent sample t-test, Pearson product difference correlation, and the stepwise regression test were adopted for data analysis.

RESULTS

Age (r = -0.41, p < 0.01), age at diagnosis (r = -0.34, p < 0.01), and sleep duration (r = -0.25, p < 0.05) were negatively correlated with rumination-reflection. The depressive symptoms (r = 0.72, p < 0.01) were positively correlated with rumination, whereas rumination (r = 0.57, p < 0.01) and suicide ideation were positively correlated. Depressive symptoms and rumination could predict suicide ideation, and the effective explanatory power reached 60%.

CONCLUSIONS

If the patient with depression was younger or the patient was diagnosed at a younger age, the depressive symptoms of the reflection subscale of rumination thinking and suicide ideation were more serious. Our results indicate that clinicians who care for patients with depression should be aware of rumination and its impact on suicide ideation, specifically in younger patients.

The Suicidal Ideation Attributes Scale-Modified (SIDAS-M): Development and preliminary validation of a new scale for the measurement of suicidal ideation in autistic adults

LAY ABSTRACT

Autistic people may be at higher risk of suicidal behavior than people in the general population. Suicidal behavior may include thinking about suicide or attempting to end one's own life by suicide. It is important to identify autistic people who may be thinking about suicide. People who are at risk of suicidal behavior can be identified by asking questions about whether they have been thinking about suicide. A specially designed questionnaire, or screening instrument, can help someone ask the best questions to find out if someone has been thinking about suicide. This information can help to identify supports to be put in place to prevent suicidal behavior, such as a suicide attempt. However, autistic people may interpret questions differently than non-autistic people. It is important to use screening tools that have been designed with, and for autistic people. In this study, we examined the Suicidal Ideation Attributes Scale (SIDAS). The SIDAS is an existing tool that was developed to screen for suicidal thinking in the general population. We modified SIDAS for use with autistic adults. We involved autistic people in the process of modifying SIDAS. We called the modified instrument the SIDAS-M. The results of our study showed SIDAS-M may be useful for screening for suicidal thinking in autistic adults who do not have an intellectual disability.

Neuroticism, rumination, depression and suicidal ideation: A moderated serial mediation model across four countries

Background/objective

Research has highlighted the role of neuroticism, rumination, and depression in predicting suicidal thoughts, but studies on how these variables interplay are scarce. The aims of the present study were to test a model in which emotional stability (i.e., low neuroticism) would act as an antecedent and moderator of rumination and depressed mood in the prediction of suicidal ideation (i.e., moderated serial-mediation), and to explore their replicability across four countries and sex, among college students as an at-risk-group for suicide.

Method

Participants were 3482 undergraduates from U.S, Spain, Argentina, and the Netherlands. Path analysis and multi-group analysis were conducted.

Results

Emotional stability was indirectly linked to suicidal ideation via rumination and depressed mood. Moreover, emotional stability moderated the associations between rumination and depressed mood, and between depressed mood and suicidal ideation. Findings were consistent in males and females, and across countries studied.

Discussion

Regardless of sex and country, people with low emotional stability reported higher levels of rumination, which in turn was associated with more depressed mood, and these were associated with higher reports of suicidal thoughts. This cascade of psychological risk factors for suicidal ideation seems to be more harmful in people who endorse low levels of emotional stability.

The psychological effects of imprisonment: The role of cognitive, psychopathic and affective traits

The present cross-sectional correlational study aimed to investigate a set of cognitive, affective, and personality traits impacting the psychological effects of imprisonment. Ninety-three male inmates filled out a battery including measures of intelligence, working memory, psychopathy, aggressiveness, anxious trait, emotionality, rumination styles, and empathy proneness. Inmates' psychological outcomes were conceptualized in terms of mood, anxiety, depression, and general health. Results showed that inmates with high cognitive abilities, psychopathic impulsivity, proactive aggression, personal distress and fantasy, anxious and negative emotionality are mainly prone to ill-being psychological outcomes. Contrariwise, the fearless dominance trait, positive emotionality and empathic concern ability seem to expose inmates to positive psychological outcomes. Reactive aggression and perspective taking seem to impact both positive and negative moods. Ruminative style was unrelated to psychological outcomes. These preliminary results provide an insight into which factors intervention programs should be based upon in order to enhance well-being and reduce distress among inmates.

Emotion-related impulsivity and rumination: Unique and conjoint effects on suicidal ideation, suicide attempts, and nonsuicidal self-injury across two samples

INTRODUCTION

Rumination and emotion-related impulsivity predict suicidal ideation, suicide attempts, and nonsuicidal self-injury (NSSI). Because rumination and emotion-related impulsivity, though, are highly correlated, we consider their unique vs. conjoint influence on suicidal ideation and self-harm.

METHOD

Across two samples of adults (N's = 171 and 191), we examined how rumination and emotion-related impulsivity relate to suicidal ideation, suicide attempts, and NSSI. We assess the more general process of repetitive negative thinking and the more specific process of suicide-related rumination. Participants completed the Three-Factor Impulsivity Index and the self-report Columbia-Suicide Severity Rating Scale. Those in sample 1 completed the Perseverative Thinking Questionnaire and the Deliberate Self-Harm Inventory, and those in Sample 2 completed the Suicide Rumination Scale.

RESULTS

Emotion-related impulsivity and both forms of rumination showed robust bivariate correlations with suicidal ideation, suicide attempts, and NSSI. Neither rumination or impulsivity related to suicide attempts controlling for ideation or to NSSI. In multivariable analyses, emotion-related impulsivity but not general rumination was tied to suicidal ideation. In contrast, suicide-related rumination was more directly tied to suicidal ideation than was impulsivity.

CONCLUSIONS

Findings provide support for a more nuanced approach to the forms of impulsivity and rumination related to suicidal ideation.

Longitudinal relationships between guilt and suicide risk among adolescents in a postdisaster context: Mediating roles of rumination and posttraumatic stress disorder

OBJECTIVE

To analyze the pathways and mechanisms underlying the impact of guilt on suicide risk using a well-controlled longitudinal study, we examined the mediating roles of intrusive rumination, deliberate rumination, and posttraumatic stress disorder (PTSD) in this association.

METHOD

Four hundred and eight adolescent survivors (M_age  = 14.05 years) were assessed using self-report questionnaires three and a half years and four and a half years after the Ya'an earthquake. The self-report questionnaires included the Trauma Exposures Questionnaire, the Interpersonal Guilt Questionnaire, the Event-Related Rumination Inventory, the PTSD Checklist for the DSM-5, and the Child Behavior Problems Questionnaire.

RESULTS

The results indicated that guilt had a direct and positive effect on suicide risk. Intrusive rumination and PTSD mediated the relationship between guilt and suicide risk. Guilt could increase deliberate rumination, but deliberate rumination did not significantly predict PTSD and suicide risk.

CONCLUSION

Negative postdisaster emotions, such as guilt, can enhance the combined effects of cognition and psychological disorders on suicide risk. Guilt affects suicide risk indirectly through intrusive rumination and PTSD but not through deliberate rumination.

Psychological strain and suicidal ideation in young university students during Covid-19 outbreak: the mediating roles of rumination and depression

The link between psychological strain and suicidal ideation is well embedded in literature, however, the underlying mechanism is rarely explored. Therefore, this study aimed to examine the relationship between psychological strain, suicidal ideation, rumination, and depression among Pakistani young adults during the Covid-19 outbreak. In addition, it will also try to determine the mediating role of ruminative subtypes and depression in the relationship between psychological strain and suicidal ideation. The sample consists of 400 university students (83 males and 289 females) with the age range from 18 to 30 years (M = 22.25, SD = 2.40). Psychological strain scale, Suicidal Ideation Scale, Beck Depression Inventory, and Ruminative Response Scale were administered to the participants. Results indicated a significant and positive association between the study variables. Psychological strain positively influenced suicidal ideation both directly, and indirectly via brooding and depression. Both variables were found to be serially mediated by the brooding subtype of rumination and depression and not with the reflective subtype. Strain theory of suicide and response style theory also postulated important insights regarding the association of these variables in young adults, among which, strain is serially related to first brooding and then depression, which is eventually related to suicidal ideation. The present study makes a significant contribution to the literature by providing a unique conceptual and theoretical framework to identify suicide at the ideation level before it proceeds to behavior during this unprecedented time of the pandemic outbreak.

Depression and suicide attempts in Chinese adolescents with mood disorders: the mediating role of rumination

Mood disorders (MD) are often associated with a higher incidence of suicidal behavior, especially in adolescent patients. However, the mechanisms by which depression affects suicide attempts in adolescents with MD remain poorly elucidated. Therefore, the purpose of this study was to determine the incidence, risk factors, and clinical correlates of suicide attempts in Chinese adolescent patients with MD, as well as the inter-relationship between depressive symptoms, rumination, and suicide attempts, and the role of rumination in mediating depression and suicide attempts. A total of 331 MD adolescent patients aged 11 ~ 18 years were recruited from a psychiatric hospital. Suicide attempts were assessed with the MINI Suicide Scale. Depressed symptoms were measured with the Patient Health Questionnaire-9 (PHQ-9). To assess rumination, we used the 21-item Chinese version of the Ruminative Responses Scale (RRS). Overall, the percentage of suicide attempts among MD adolescents was 51.96%, with a higher percentage of females (58.62%) than males (36.36%). Compared to non-suicide attempters, suicide attempters had higher scores on PHQ-9, RRS, depression-related, brooding, and reflective pondering. Gender and RRS were independently associated with suicide attempts. Rumination played a fully mediating role between depression and suicide attempts. In addition, the mediating effect of depression between rumination and suicide attempts was not significant. The incidence of suicide attempts was higher in MD adolescents than in general adolescents. Gender and rumination were associated with suicide attempts in MD adolescents. Moreover, rumination mediated the correlation between depressive symptoms and suicide attempts, suggesting that rumination may be an important intervention component for clinical staff to prevent suicidal behavior in adolescents with MD.

Development and validation of a new scale to measure chronic suicidal ideation: The Chronic Suicidal Ideation Inventory-5 (CSI-5)

OBJECTIVE

Little is known about characteristics that differentiate acute from chronic suicidal ideation. Studies have been hampered by the lack of a formal operational definition or measurement tool for chronic suicidal ideation (CSI). We sought to adapt a standardized measure of obsessive-compulsive thinking to rate chronic suicidal ideation in a mood disorder inpatient cohort.

METHOD

We devised a novel self-report instrument, based on constructs related to obsessive-compulsive thinking and the Yale-Brown Obsessive-Compulsive Scale (Y-BOCS), as applied to preoccupations with suicidal thoughts and their persistence over 24 months in a previously described cohort of 97 inpatients with mood disorder. Exploratory factor analysis and principal components analysis were used to establish the factor structure of the instrument, and Cronbach's alpha and McDonald's omega were calculated to determine internal consistency of the scale.

RESULTS

Significant Pearson correlations with individual scale items and total CSI-5 scores were evident in relation to the 2-, 6-, 12- and 24-month periods preceding the index hospitalization. A one-factor solution explained 75% of the variance in total CSI-5 scores. Cronbach's alpha was 0.914, and McDonalds's omega was 0.916. CSI-5 scores were not significantly associated with current depression severity scores or actual past suicide attempts.

CONCLUSIONS

This 5-item adaptation of Y-BOCS-type questions provides an internally consistent and reliable assessment of chronic suicidal ideation in patients with mood disorder. The integrated assessment of time occupied by suicidal thoughts, activity interference, associated distress, efforts to resist suicidal thoughts, and degree of control over suicidal thinking provides a cohesive framework for understanding chronic suicidal ideation.

Defeat, entrapment, and suicidal ideation: Twelve-month trajectories

BACKGROUND

Defeat and entrapment have been highlighted in the development of suicidal ideation within the Integrated Motivational-Volitional model of suicidal behavior. Research suggests that entrapment has to be differentiated into internal and external entrapment. The aim of this study was to investigate the associations between defeat, internal, external entrapment, and suicidal ideation within and prospectively over measurements.

METHODS

A sample of 308 psychiatric inpatients (53% female) aged 18 to 81 years (M = 36.92, SD = 14.30) was assessed for the four constructs after admission to a psychiatric ward and six, nine, and twelve months later. Multilevel analyses were conducted to examine associations.

RESULTS

Defeat was associated with (a change in) internal and external entrapment. Defeat predicted a change in internal entrapment over time. Defeat and internal, but not external, entrapment were associated with (a change in) suicidal ideation. Internal entrapment was able to predict suicidal ideation. Internal entrapment and defeat predicted a change in suicidal ideation over time.

CONCLUSION

Results highlight the importance to distinguish between internal and external entrapment, and their specific association with suicidal ideation. Perceptions of internal entrapment are of central relevance when experiencing suicidal ideation and should be considered in clinical practice.

Suicidal ideation among Chinese survivors of childhood sexual abuse: Associations with rumination and perceived social support

BACKGROUND

Although previous studies have shown that childhood sexual abuse (CSA) experiences might be related to suicidal ideation in later life, its associations with rumination and perceived social support (PSS) remain unclear.

OBJECTIVE

The present study aimed to expand prior findings among Chinese survivors of CSA to investigate rumination's effect on the association between CSA and suicidal ideation, and the potential moderating role of PSS in this relationship.

METHODS

The Childhood Sexual Abuse Questionnaire, the Ruminative Response Scale, the Multi-dimensional Scale of Perceived Social Support, and the Symptom Checklist were completed by 6834 college students (56.61% females).

RESULTS

In all, 1400 (20.76%) students reported experiences of CSA. The rate of CSA in males was higher than that in females (24.23% vs. 18.10%). Students with CSA experiences reported a higher level of suicidal ideation than those without such experiences. CSA and rumination were positively related to suicidal ideation, and PSS were negatively related to CSA, rumination and suicidal ideation. CSA predicted suicidal ideation both directly and indirectly through rumination. PSS moderated the effect of rumination on suicidal ideation.

CONCLUSIONS

This study provides evidence for the effects of rumination on the association between CSA and suicidal ideation, and the buffering role of PSS on the relationship between rumination and suicidal ideation in Chinese survivors with CSA experiences. These findings suggest that developing adaptive emotional regulation strategies and enhancing the level of PSS might contribute to the alleviation of negative influences from CSA.

Mind wandering and depression: A status report

While many clinical studies and overviews on the contribution of rumination to depression exist, relatively little information regarding the role of mind wandering (MW) in general is available. Therefore, it remains an open question whether patterns of MW are altered in depression and, if so, how these alterations are related to rumination. Here, we review and discuss studies investigating MW in cohorts, showing either a clinically significant depression or with clinically significant disorders accompanied by depressive symptoms. These studies yield first tentative insights into major issues. However, further investigations are required, specifically studies which: i) compare patients with a primary diagnosis of major depression with healthy and appropriately matched controls, ii) implement measures of both MW and rumination, iii) are based on experience sampling (in combination with other key approaches), iv) compare experience sampling during daily life, resting state and attentional tasks, v) explore possible biases in the assessment of MW, vi) acquire data not only related to the propensity and contents of MW, but also regarding meta-awareness and intentionality.

Age effects on clinical and neurocognitive risk factors for suicide attempt in depression - Findings from the AFSP lifespan study

BACKGROUND

Studies of risk factors for suicidal behavior are typically restricted to narrow age ranges, making it difficult to determine if they have the same relevance or potency across the full adult lifespan.

METHODS

This study examined selected clinical and neurocognitive risk factors for suicidal behavior - borderline personality traits, aggression, depressive rumination, memory performance, and language fluency- in a multi-site sample (N = 309, ages 16-80) of depressed patients with a recent (last 5 years) suicide attempt or no history of attempt, and demographically similar non-psychiatric controls. We examined cross-sectional age and attempter/non-attempter differences on these risk factors, and whether certain risk factors were more prominent discriminators of past suicide attempt earlier or later in the lifespan. Correlations with age were computed, and logistic regression was used to classify attempter status based on each risk factor and its interaction with age.

RESULTS

Nearly all risk factors were negatively correlated with age. Borderline traits, aggression, memory, and category fluency each predicted attempter status (p < 0.05), but these effects were not different across ages. In contrast, the association between rumination and suicide attempt status differed across the lifespan, becoming a stronger discriminator of past suicidal behavior at older ages.

LIMITATIONS

The cross-sectional design limits our developmental findings.

CONCLUSIONS

Despite age-related changes in symptom severity or neurocognitive performance, key risk factors for suicidal behavior previously identified in studies with more restricted age-ranges are salient throughout the adult lifespan. In contrast, depressive rumination may be particularly salient in later life.

The relationship between rumination and NSSI: A systematic review and meta-analysis

BACKGROUND

Rumination is a cognitive process that has been implicated in the onset and maintenance of a variety of psychological difficulties. The purpose of this review and meta-analysis was to examine the nature and strength of the relationship between rumination and non-suicidal self-injury (NSSI).

METHODS

The protocol for this review was pre-registered (CRD42019148186). A literature search of electronic databases PsycINFO, CINAHL, MEDLINE, and Web of Science was performed from the earliest date available to March 2020. Thirty-nine eligible papers were identified. An additional seven papers were identified from a search conducted in September 2021, resulting in a total of 46 papers. Separate meta-analyses were undertaken for NSSI frequency and NSSI history, with studies grouped by rumination type (depressive, transdiagnostic, anger, brooding, reflection, catastrophising, overall). Moderator analyses were also conducted along with a narrative synthesis of adjusted associations and longitudinal studies.

RESULTS

Rumination had a positive small association with NSSI frequency and a positive moderate association with NSSI history. The adjusted associations yielded mixed findings and most longitudinal research found rumination to be associated with prospective NSSI.

LIMITATIONS

Most included studies had a moderate risk of bias and used a student sample. A limitation of this review was that only English language papers were included.

CONCLUSIONS

Findings indicate that rumination is associated with NSSI, but more so the likelihood of engaging in NSSI overall than the frequency. Rumination-focused techniques for NSSI may therefore be of benefit. Further research is needed to understand this association, particularly with longitudinal studies that focus on state rumination rather than stable trait rumination.

PRACTITIONER POINTS

Rumination was found to have a small to moderate association with NSSI. Some individuals who engage in NSSI may benefit from psychological techniques that target rumination. Most of the studies included had a moderate risk of bias.

Psychometric Properties and Prospective Predictive Utility of the Contrast Avoidance Questionnaires

Abstract. Recent theoretical research posits that a key factor in the development and maintenance of pathological worry is the avoidance of sudden emotional shifts. Recently two self-report instruments were developed to index this phenomenon (Contrast Avoidance Questionnaire – Worry [CAQ-W] and Contrast Avoidance Questionnaire – General Emotion [CAQ-GE]). This work employed a multi-study design to provide an independent evaluation of the latent structure of these measures; additionally, the validity and longitudinal predictive ability of the measures was examined. Findings of the factor analytic work support a two-factor solution for each of the questionnaires. These were defined as the following subscales: CAQ-W: Emotional Contrast; Negative Affect, and for the CAQ-GE: Avoidance; Discomfort. Test-retest reliability of the measure was strong and the identified subscales demonstrated differential predictive ability regarding future worry and depression. Results indicate that subscales related to the experience of negative affect rather than avoidance, display predictive utility of future symptoms. These findings are somewhat discrepant with extant literature on ecological momentary assessment (EMA) assessment of contrast avoidance indicating the need for refinement in the self-report measurement of this construct.

Metacognition, rumination and suicidal ideation: An experience sampling test of the self-regulatory executive function model

A relationship between rumination and suicidal ideation is well-evidenced. A role for thought suppression has also been suggested but under-explored. The present study assessed the relative contribution of rumination and a range of thought control strategies in the understanding of suicidal ideation, within the theoretical framework of the self-regulatory executive function (S-REF) model (Wells & Matthews, 2015). Twenty-four participants who had experienced suicidal ideation in the last two months completed trait-level measures of metacognitive beliefs and momentary sampling measures of thought control strategy use, rumination and suicidal ideation over six days. Maladaptive thought control strategy use (worry and punishment), alongside rumination, predicted suicidal ideation. Adaptive strategies (distraction, social control and reappraisal) emerged as negative predictors. Metacognitive beliefs about the need to control thoughts predicted the use of punishment- but not worry-based thought control strategies. Thought control strategy use is as important in the development of suicidal ideation as rumination. The S-REF model represents a promising new approach to understanding these processes in the development of suicidal ideation.

Associations between goal orientation and suicidal thoughts and behaviors at one-month follow-up: Indirect effects through ruminative flooding

Previous research has identified both goal orientation and ruminative flooding as potential risk factors for suicidal thoughts and behaviors, as well as positive associations between goal orientation and rumination. The present study examined whether the association between goal orientation and suicidal thoughts and behaviors, assessed one month later, was accounted for by ruminative flooding. A sample of 924 psychiatric outpatients (M_age = 39.09 years, SD = 14.82, range = 18 to 84; 61.7% female; 37.0% White) completed self-report and interview measures at baseline and provided information about suicide-related outcomes at one-month follow-up. Goal orientation was positively associated with ruminative flooding, and both goal orientation and ruminative flooding were associated with suicidal thoughts and behaviors at one-month follow-up. Controlling for lifetime suicidal thoughts and behaviors, as well as patient age and sexual orientation, ruminative flooding accounted for the relationship between goal orientation and suicidal thoughts and behaviors at one-month follow-up. These findings were especially relevant for individuals with a history of multiple suicide attempts. Overall, this study provided evidence that difficulties with goal orientation may relate to suicidal thoughts and behaviors through intense ruminations perceived as a loss of cognitive control. Interventions that address ruminative thinking and cognitive flexibility may, in turn, assist in reducing emotion dysregulation and managing suicidality among those who struggle with goal orientation.

Testing Whether Suicide Capability Has a Dynamic Propensity: The Role of Affect and Arousal on Momentary Fluctuations in Suicide Capability

To prevent suicidal behaviors, it is crucial to understand the mechanisms and processes that enable an individual to act on suicidal thoughts. Suicide capability, which involves an increased pain tolerance and fearlessness of death, is a critical factor that enables an individual to endure the physical pain necessary to make a lethal suicide attempt. Extant research has largely conceptualized suicide capability as developing linearly in response to painful and provocative experiences, but the emerging literature on the temporal dynamics of suicide has been challenging the notion of linearity in suicide risk. Few studies have directly measured and compared changes in suicide capability in response to rumination on different affective states. We sought to experimentally test if rumination in the context of low vs. high arousal emotions will prompt distinct changes in two core components of suicide capability: pain tolerance and fearlessness of death on two undergraduate student samples. In both studies, participants provided measures of subjective emotional state as well as pain threshold, tolerance, and persistence before and after completing experimental manipulations which included both emotion and rumination induction procedures. In the second study, measures of fearlessness about death and physiological arousal (heart rate) were added to the experimental procedures. We found significant decreases in pain threshold, tolerance, and persistence following the experimental manipulations but found no main effects of rumination or suicide risk. These findings suggest that suicide capability can fluctuate but these changes may occur through a different mechanism and/or differ between individuals at varying levels of suicide risk.

Examination of characteristics of ruminative thinking as unique predictors of suicide-related outcomes

Rumination, a passive, repetitive perseveration on the causes, meaning, and consequences of one's distress, has been linked to suicidal ideation and behavior. Less is known, however, about which specific characteristics of rumination confer risk for suicide-related outcomes. This study examined associations between four features of rumination-frequency, duration, perceived controllability, and content-and current suicidal ideation, lifetime suicide plans, and lifetime suicide attempts. A sample of 548 adults (53.6% female, Mage = 36.54 years, 80.8% White/European American) recruited via Amazon's MTurk completed a battery of self-report measures online. The perceived controllability of rumination was uniquely associated with suicidal ideation, plans, and attempts, controlling for other characteristics of rumination, generalized worry, and demographic characteristics. Perceived controllability was also related to lifetime suicide plans and attempts above and beyond current suicidal ideation. Interpersonal and health-related content areas were also related to suicide-related outcomes, though these effects were inconsistent across outcome. Overall, perceived controllability over one's thoughts may be a key factor that confers risk along the suicidality continuum. Future research should replicate and extend these findings in diverse populations, using longitudinal designs, and with a variety of methodologies.

Repetitive negative thinking mediates the relationship between addictive Facebook use and suicide-related outcomes: A longitudinal study

Repetitive negative thinking (RNT) and addictive Facebook use have been shown to be associated with suicide ideation and suicidal behavior. The present longitudinal study aimed to investigate whether the association between addictive Facebook use and suicide-related outcomes is mediated by RNT. Data of 191 German Facebook users (M _age  = 26.17, SD _age  = 6.63) were assessed at two measurement time points over a one-year period (first measurement = T1, second measurement = T2) via online surveys. The significant positive association between addictive Facebook use (T1) and suicide-related outcomes (T2) was significantly mediated by RNT (T1). In contrast, a check test that included RNT (T1) as predictor and addictive Facebook use (T1) as mediator revealed no significant mediation effect. The current results demonstrate that if addictive Facebook use leads to RNT suicide ideation and attempts become likely. Therefore, RNT and addictive Facebook use should be taken into account when assessing individuals for risk of suicide.

Characteristics of Intrinsic Brain Functional Connectivity Alterations in Major Depressive Disorder Patients With Suicide Behavior

BACKGROUND

The intrinsic brain functional connectivity of suicide attempts in major depressive disorder (MDD) remains incompletely understood.

PURPOSE

To investigate graph-theoretical based functional connectivity strength (FCS) alterations in MDD patients with suicidal behavior.

STUDY TYPE

Prospective.

SUBJECTS

Fifty medication-free MDD patients, with (suicide attempters, SA, N = 15) and without (non-attempters, nSA, N = 35) a history of a suicide attempt, and 37 healthy controls (HC).

FIELD STRENGTH/SEQUENCE

Resting-state functional magnetic resonance imaging (fMRI) using a gradient-echo imaging sequence was acquired at 3.0 T.

ASSESSMENT

For each individual, voxel-wise whole-brain functional network was constructed and graph-theoretical based FCS map was calculated. For each individual in two patient groups, the seed-based functional connectivity map was constructed.

STATISTICAL TESTS

Non-parameter permutation tests, analysis of covariance, two-sample t-test, Chi-square test, and Pearson correlation analysis. A P value <0.05 was considered statistically significant.

RESULTS

Relative to the HC group, two MDD patient groups showed significantly lower FCS in the left hippocampus, while nSA patients showed additionally lower FCS in more widespread regions (P < 0.05). Importantly, comparing to nSA patients, SA patients had significantly higher FCS in the right orbitofrontal cortex (OFC) and bilateral dorsomedial prefrontal cortex (dmPFC) (P < 0.05). Further seed-based functional connectivity analysis revealed that the right OFC exhibited significantly higher connectivity to right middle frontal gyrus and lower connectivity to the left anterior cingulate cortex and left calcarine sulcus, and the bilateral dmPFC had significantly higher connectivity to the left middle frontal gyrus and right inferior temporal gyrus in the SA patients than in the nSA patients (P < 0.05).

DATA CONCLUSION

This study identified disconnections of the OFC and dmPFC which were putatively related to a higher risk of suicidal behavior in MDD patients, thus extended the understanding of suicidal behavior at a brain circuit level.

The Characteristics and Benefits of Disclosing Personal Experiences in Prison: A Study of the Writing Paradigm

The aim of this study is to investigate the characteristics and benefits of writing about personal experiences in prison. A variation of the classic writing paradigm was proposed to a sample of 93 male inmates in southern Italian prisons. Participants were left to write on any personal experience related to their condition and time in prison in 4 daily sessions. Measures of subjective well-being were collected across the sessions. Transcripts were analyzed through sentiment analysis. Cognitive and executive functioning indices (i.e., general cognitive abilities, working memory capacity, inhibition, and shifting) are included as covariates in our analyses on the evolution of well-being measures. Results showed that participants’ well-being improved across the sessions, independent of the emotional valence of the disclosed experience. This effect was partly modulated by the participant’s measure of working memory capacity. After an initial simplification, narrative productions appeared to increase their length and complexity. Our results support the idea that emotional disclosure in our sample of inmates contributes to social integration. Results encourage the adoption of writing procedures, as they are inexpensive and effective in supporting prisoners’ adjustment to prison life.

"It was like nobody cared about what I said?" Iranian women committed self-immolation: a qualitative study

BACKGROUND

Suicide-attempts have increased across the world and have become higher among females. There has been a high prevalence of self-immolation in Iran, mostly young married women admitted to the burn centers. This study aimed to explore the factors and experiences of self-immolation in Iranian married women to develop prevention strategies to prevent the personal, social, and economic impacts of suicide and suicide attempts.

METHODS

A qualitative descriptive approach using open-ended, in-depth, face-to-face interviews was conducted in a purposive sample of 16 married Iranian women aged 16-40 years in the burn centers in Urmia city, a place in northwest Iran. Conventional content analysis was used to analyze the data.

RESULTS

Three themes emerged from the data, including (1) antecedents of self-immolation, (2) suicidal ideation method, and (3) pathway to recovery. Each of these themes is supported by sub-themes.

CONCLUSIONS

The study highlights the demand for health professionals to support self-immolation survivors to continue their normal lives. According to survivors' needs, a comprehensive supportive program is recommended to support their pathways to recovery in all its complexities. Health professionals should also not forget that the survivors' family also will need help to overcome this trauma. A family counseling program may also be provided.

Metacognitive Training for Depression: Feasibility, safety and acceptability of two new treatment modules to reduce suicidality

Recent evidence favours psychological interventions explicitly targeting suicidality; however, group treatments on suicidality are rare and are assumed to have unfavourable effects. We developed two modules specifically addressing suicidality that replace two existing modules in the Metacognitive Training for Depression (D-MCT). The aim of the current study was to examine the feasibility, safety, and acceptability of this intervention (D-MCT/S). Forty-eight inpatients with depression received eight sessions of D-MCT/S over 4 weeks in addition to standard treatment. Patients were assessed before the training, 4 and 8 weeks later regarding suicidality (primary outcome: Beck Suicide Scale [BSS]), hopelessness, depression (e.g. Hamilton Depression Rating Scale [HDRS]), dysfunctional attitudes, and self-esteem. Negative effects of the modules and subjective appraisal were assessed. Suicidality, hopelessness, and depression decreased over time. Whereas the effects on the BSS only reached trend level, a large effect was observed when the suicide item of the HDRS was used. Two of the 46 patients (4%) reported a deterioration in their symptoms, but this was not associated with the D-MCT/S. Negative effects of the general training were rather low, and acceptability was high. In general, patients evaluated the two new modules on suicidality similarly to the established modules. However, both modules were assessed as distressing by 39% of the patients. When we addressed suicidality in the D-MCT/S, we did not observe any contagious effects. In fact, the pilot versions of the two modules on suicidality are promising in terms of feasibility, safety, and acceptability. The results will be used to improve current shortcomings. The trial was registered with the German Clinical Trials Register (#DRKS-ID: DRKS00010543) on 23 August 2016.

How to Cope with Perfectionism? Perfectionism as a Risk Factor for Suicidality and the Role of Cognitive Coping in Adolescents

Suicide among adolescents is a significant health concern. Gaining more knowledge about markers that contribute to or protect against suicide is crucial. Perfectionism is found to be a personality trait that is strongly predictive for suicidality; it can be divided into personal standards perfectionism (PS) and concerns about mistakes and doubts perfectionism (CMD). This study investigated the association between PS, CMD, and suicidality in a sample of 273 Dutch secondary school students aged between 12 and 15 years old (M = 13.54, SD = 0.58, 55.8% males). We also examined whether adaptive, or maladaptive cognitive coping strategies influenced these associations. We hypothesized that students high in PS or CMD would experience an increased suicidality. Moreover, we expected that adaptive coping strategies would act as buffer between the association of perfectionism and suicidality, and that maladaptive coping strategies would strengthen this association. For analyses, we used a regression model with latent variables. The results showed that higher scores in perfectionism (PS and CMD) were related to an increase in suicidality. High levels of maladaptive coping in combination with high levels of perfectionism were associated with an increase in suicidality. Although adaptive coping was related to a decrease in suicidality, adaptive coping in interaction with PS and with CMD was not a predictor of suicidality. The results are relevant for prevention, and intervention programs. This paper makes recommendations for clinical practice and further research in order to prevent suicidality in adolescents.

Ecological Studies of Sleep Disturbances During Suicidal Crises

PURPOSE OF REVIEW

Several reviews and metanalyses have shown that sleep disturbances, such as insomnia and nightmares, can predict suicidal ideations and behaviors. Common physio-pathological pathways may explain this relationship. However, only in recent years, some research groups have tried to apply this knowledge in the quest for a reliable tool of suicide risk prediction. We aim to describe in this paper the results of studies using ecological or quasi-ecological assessment methods that connect sleep disturbances and suicide risk.

RECENT FINDINGS

Our review confirms the paucity of studies on this topic. The few studies that we could analyze suggest the interest of ecological methods of sleep assessment since sleep disturbances predicted the onset or worsening of suicidal ideations and behaviors. Ecological assessment of sleep can help to understand how sleep disturbances contribute to the emergence of suicidal ideations and behaviors. Sleep disturbances appear as a promising "real-life" marker of risk, but further studies are needed to determine if sleep monitoring could guide preventive interventions.

Maladaptive mood repair predicts suicidal behaviors among young adults with depression histories

BACKGROUND

As the rates of suicidal behaviors continue to rise, research is needed that can facilitate prevention. The present study therefore examined whether a modifiable process, dysfunctional regulation of sadness (maladaptive mood repair), predicts a range of suicidal behaviors and if its impact is affected by risk and protective factors.

METHODS

Young adults with histories of childhood-onset mood disorder (COMD) (n = 173) or no histories of major psychiatric illness (controls, n = 96) were followed for approximately 3 years. Self-rated questionnaires and psychiatric evaluations were administered at study entry (T1) and across the follow-up (T2) and clinicians assessed the DSM-range of non-fatal suicidal behaviors. We hypothesized that the impact of depression on suicidal behaviors was mediated by dysfunctional regulation of sadness.

RESULTS

At T1, 90% of the COMD group had histories of various suicidal behaviors; 63% had past suicide attempts. During follow-up, 40% exhibited suicidal behaviors; 7% reported suicide attempts. Controlling for prior suicidal behaviors, T1 maladaptive mood repair predicted suicidal behavior during the follow-up and differentiated recurrent thoughts of death from other forms of suicidality. Protective and risk factors lost their predictive power in the presence of maladaptive mood repair.

LIMITATIONS

Few control cases exhibited suicidal behavior during the follow-up and the high inter-correlations among several key variables constrained the models that could be fitted.

CONCLUSIONS

Programs to prevent suicidal behavior among high-risk individuals should include maladaptive mood repair as an intervention target. Further research is needed on whether recurrent thoughts of death constitute a valid index of suicidality.
