Clinical characteristics of suicidal behavior in first hospitalization and drug-naïve patients with major depressive disorder

BackgroundMajor depressive disorder (MDD) is a major and common cause of suicide. The purpose of this article is to report the clinical characteristics and patterns of co-morbid suicidal behavior (SB) in first hospitalized and drug-naïve MDD patients.MethodsA total of 345 patients with first hospitalization and drug-naïve MDD with SB were included in this study, while 183 patients without SB were included as a control group. We collected socio-demographic, general clinical data and common biochemical indicators of all participants and assessed their clinical symptoms.ResultsCompared to patients without SB, MDD with SB had more severe clinical symptoms and worse metabolic indicators. Duration of disease, depressive symptom scores, and thyroid stimulating hormone (TSH) levels was risk factors for SB and its number.ConclusionsMDD patients with SB suffered more severe clinical symptoms and worse metabolic indicators, and risk factors for SB in this population were identified, which may provide beneficial insight and reference for clinical prevention and intervention of SB in MDD patients.

Suicidal ideation, plan, and attempt among men who have sex with men in Nepal: Findings from a cross-sectional study.

Men who have sex with men (MSM) are at increased risk for suicide, with a much higher prevalence of suicidality than the general population. While there is a growing interest in the identification of risk factors for suicidal behaviors globally, the understanding of the prevalence and risk factors for suicidal behaviors among MSM in the context of low- and middle-income countries is almost non-existent. Therefore, this study aimed to investigate suicidal ideation, plan, and attempts, and related factors among MSM in Nepal. A cross-sectional respondent driven survey was conducted on 250 MSM between October and December 2022. Bivariate and multivariable logistic regression was used to evaluate independent correlates of suicidal behaviors of MSM. Overall, the lifetime prevalence of suicidal ideation, plans, and attempts among MSM in this study were 42.4%, 31.2%, and 21.6%, respectively. MSM with depressive symptoms (aOR = 5.7, 95% CI = 2.4-14.1), advanced education (higher secondary and above; aOR = 2.9, 95% CI = 1.4-6.1), and smoking habit (aOR = 2.5, 95% CI = 1.2-5.3) were at increased risk for suicidal ideation. Similarly, those with depressive symptoms (aOR = 2.2, 95% CI = 1.1-4.8) and advanced education (aOR = 2.7, 95% CI = 1.2-5.7) were more likely to plan suicide, whereas young MSM were significantly more prone to attempting suicide (aOR = 2.7, 95% CI = 1.3-5.8). Interestingly, MSM with moderate to severe food insecurity were 2-3 times more likely to think about, plan, or attempt suicide (ideation: aOR = 3.5, 95% CI = 1.6-7.7; plan: aOR = 3.7, 95% CI = 1.6-8.3; attempt: aOR = 2.2, 95% CI = 1.1-4.6). The results suggest the importance of early assessment of suicidal behaviors among MSM and the need for tailored interventions to simultaneously address mental health problems and food insecurity to reduce suicide-related problems among Nepalese MSM.

Gender Differences in Risks of Suicide and Suicidal Behaviors in the USA: A Narrative Review.

We review recent research (2018-2023) on gender differences in suicidal behaviors (i.e., suicidal ideations and attempts, death by suicide). We examine research studies in the following areas: developmental period, substance use, and special populations (Veterans, sexual and gender minorities). Novel results were found in these different areas. For example, suicide rates for female youth are increasing at a faster rate relative to male youth. Further, some evidence suggests that heavy alcohol use/binge drinking is a significant and growing risk factor for suicidal behaviors in women. Military service may be a more significant risk factor for suicidal behaviors among male Veterans compared to female Veterans. Additionally, suicide rates are rising for gender minority youth/young adults. Recent research on gender differences in suicide outcomes demonstrates findings that align with previous research, as well as new insights on this important topic.

Nonsuicidal self-injury characteristics: A mixed methods analysis of differences between veterans and civilians

Nonsuicidal self-injury (NSSI) is a well-established risk factor for suicidal behavior, with certain NSSI characteristics being associated with increased risk. In the United States (U.S.), the veteran suicide rate is elevated, though lifetime prevalence rates of NSSI appear similar between veterans and civilians. There is limited research that directly compares veterans and civilians across multiple NSSI characteristics to examine between-group differences in NSSI behavior and provide important context for the application of NSSI research with the veteran population. This study examined differences between U.S. veterans and civilians with a history of suicidal ideation across several NSSI characteristics, including method, severity, age of onset, shame, distress, and reason for initial NSSI engagement. A sample of 527 veterans and civilians completed measures of direct and indirect NSSI behaviors along with supplemental questions designed to further assess endorsed NSSI behaviors. Additionally, respondents provided written responses to an open-ended question about their reasons for initial engagement in NSSI, which were coded for post-hoc analysis. Chi-square difference tests and t-tests were conducted, revealing significant group differences between veterans and civilians in NSSI method, lifetime versatility, age of onset, age at last occurrence, and reasons for initial engagement. No significant differences were found in NSSI frequency, severity, shame, or distress. These findings provide valuable information on similarities and differences in NSSI behavior characteristics between U.S. veterans and civilians with lifetime suicidal ideation to inform future research and the assessment of NSSI in these populations.

The relationship between mood disorders, personality disorder and suicidality in adolescence: does general personality disturbance play a significant role in predicting suicidal behavior?

IntroductionCurrent research points to the importance personality pathology and Major Depression e as relevant psycopathological risk factors for understanding suicidal risk in adolescence. Literature has mainly focused on the role of BPD, however current orientations in personality pathological functioning suggest that BPD may be the representative of a general personality disturbance, a factor of vulnerability underlying diverse psychopathological variants and aspects of maladaptive functioning. However, recent studies seem to have neglected the contributions that other specific personality disorders and personality pathology as a general factor of vulnerability for suicidality; and only marginally investigated the interaction of personality disorder (PD) as an overall diagnosis and individual PDs and major depression (MDD).In this paper, the independent and cumulative effects of MDD and DSM-IV PDs on suicidal risk are investigated in a sample of adolescents observed in a longitudinal window of observation ranging from three months preceding the assessment to a six-month follow up period of clinical monitoring.MethodsA sample of 118 adolescents (mean age = 15.48 ± 1.14) referred for assessment and treatment on account of suicidal ideation or behavior were administered the CSSRS, SCID II, Kiddie-SADS at admission at inpatient and outpatient Units. All subjects included in the study had reported suicidal ideation or suicide attempts at the C-SSRS; The CSSRS was applied again to all patients who reported further suicidal episodes during the six-months follow-up period of clinical monitoring. Dimensional diagnoses of PDs was obtained by summing the number of criteria met by each subject at SCID-%-PD 5, In order, to test the significance of the associations between the variables chosen as predictors (categorical and dimensional PDs and MD diagnosis), and the suicidal outcomes variables suicide attempts, number of suicide attempts and potential lethality of suicide attempt, non-parametric bivariate correlations, logistic regression models and mixed-effects Poisson regression were performed PD.ResultsThe categorical and dimensional diagnosis of PD showed to be a significant risk factors for suicide attempt and their recurrence, independently of BPD, that anyway was confirmed to be a specific significant risk factor for suicidal behaviors. Furthermore, PD assessed at a categorical and dimensional level and Major Depression exert an influence on suicidal behaviors and their lethality both as independent and cumulative risk factors.LimitationsBesides incorporating dimensional thinking into our approach to assessing psychopathology, our study still relied on traditionally defined assessment of PD. Future studies should include AMPD-defined personality pathology in adolescence to truly represent dimensional thinking.ConclusionThese results point to the importance of early identification of the level of severity of personality pathology at large and its co-occurrence with Major Depression for the management of suicidal risk in adolescence.

Cyberbullying victimization and suicide ideation: The mediating role of psychological distress among Malaysian youth

Cyberbullying is a pervasive phenomenon in the digital age and has been recently recognized as a risk factor for suicidal behavior among Malaysian youth. In this study, we aim to further examine the impact of cyberbullying on suicide ideation and to explore mechanisms that may explain this relationship. Building on the Conservation of Resources Theory, we test a path model in which we expect cyberbullying exposure to be related to feelings of anxiety, exhaustion, and stress, which in turn are expected to be related to an increase in depression. Finally, this negative spiral is further expected to be associated with an increase in suicide ideation. We collected online data from 534 Malaysian youth aged 15 to 26 using Google Forms. The data were analyzed using Smart PLS 3.0. The findings revealed that victims of cyberbullying incurred a significantly higher risk of suicide ideation. Mediation analyses indicated that anxiety, exhaustion, and stress mediated the relationship between cyberbullying and depression, whereas depression significantly mediated the relationship between cyberbullying and suicide ideation. The results highlight the clear need for cyberbullying prevention programs to educate youth about the consequences of cyberbullying.

Differentiating the associations between alcohol use, cigarette smoking, and conditional suicidal behaviors among adolescents

BackgroundBoth alcohol use and cigarette smoking have been identified as risk factors for suicidal behaviors. However, suicide is a process from ideation to action, and some evidence have implied us that alcohol use and cigarette smoking may play different roles in the different process of suicidal behaviors. MethodsData was derived from the 2019 Youth Risk Behavior Survey (YRBS), and a total of 12, 487 valid samples were analyzed in the study. To distinguish the different situation of suicidal behaviors, participants were divided into general people without any suicidal behavior (GNS), suicidal ideators without plan or attempt (SINPA), suicide planners without attempt (SPNA), and suicide attempters (SA).11GNS denotes to general people without any suicidal behavior, SINPA denotes to suicidal ideators without plan or attempt, SPNA denotes to suicide planners without attempt, SA denotes to suicide attempters. ResultsThe prevalence of suicidal ideation, plan, and attempt were 19.4 %, 15.9 %, and 7.7 %, respectively. Comparing to GNS, alcohol use and cigarette smoking were associated with SINPA (OR = 1.27, P < 0.05; OR = 1.47, P < 0.001), SPNA (OR = 1.29, P < 0.01; OR = 1.26, P < 0.01), and SA (OR = 1.31, P < 0.01; OR = 2.11, P < 0.001). However, alcohol use was not associated with SA comparing to SINPA (OR = 1.05, P > 0.05) and SPNA (OR = 1.03, P > 0.05), while cigarette smoking was associated with SA (OR = 1.40, P < 0.01; OR = 1.74, P < 0.001). LimitationsFirstly, using the secondary data was possibly limited. Next, this was a cross-sectional study, the casual relationship was unsure. Lastly, the amount of alcohol consumption and cigarette smoking status were not considered. ConclusionBoth alcohol use and cigarette smoking are risk factors for any suicidal behaviors. However, controlling alcohol use may be a limited method to prevent the further suicidal behaviors for ideators and planners. Managing cigarette smoking should be considered.

Assessment of risk factors for suicidal behavior: results from the Tehran University of Medical Sciences Employees' Cohort study.

Suicide is a major issue of concern for public health. It is estimated that suicide accounts for 700,000 deaths every year. A personal history of one or more suicide attempts is the most important determinant of suicide among the general population. This study aimed to assess the major risk factors associated with suicidal behaviors among Iranian employees in a medical setting. In this study, 3,913 employees of Tehran University of Medical Sciences who participated in the employees' cohort study conducted by the university were recruited. Suicidal behaviors (SBs) and their associated risk factors were evaluated using the World Mental Health Composite International Diagnostic Interview (CIDI) Version 3.0. Univariate and multivariate logistic regressions were performed to identify the determinants of SBs among the participants, and crude and adjusted odds ratios (ORs) with corresponding 95% confidence intervals (95% CIs) were calculated. Overall, 49.6% of respondents (n = 1,939) reported that they were tired of life and thinking about death. The lifetime prevalence rate of suicidal ideation (SI) was 8.1% (n = 317), that of suicide planning (SP) was 7.3% (n = 287), and that of suicide attempts (SA) was 3.1% (n = 122). Being female (OR: 1.87, CI: 1.64-2.12), being divorced (OR: 3.13, CI: 1.88-5.22), having a low level of education (OR: 1.57, CI: 1.15-2.14), and working in clinical and medical services (OR: 1.25, CI: 1.09-1.43) were associated with being tired of life and thinking about death. These factors were also associated with SI, SP, and SA. These findings highlight the need to prioritize mental health for suicide prevention, especially for high-risk groups, in workplace mental health promotion programs and policies.

Trajectories of adolescent suicidal ideation and depressive symptoms during partial hospitalization: Clinical and demographic characteristics as predictors of change.

Partial hospital programs (PHPs) are a vital mental health service for youth at risk for suicide. Yet, few studies have examined trajectories of suicidal ideation and depressive symptoms, two important risk factors for suicidal behavior, over the course of care. Moreover, little is known about factors that may impact these trajectories among youth in PHPs. The present study examined trajectories of suicidal ideation and depressive symptoms, as well as clinical and demographic predictors of these changes, among youth enrolled in two PHPs. A sample of 253 youth (Mage = 15.3; SD = 1.4; range = 12-18; 68.8% female; 63.2% White; 75.1% non-Hispanic/Latino/a/x) completed repeated measures of suicidal ideation severity and depressive symptoms during treatment. Trajectories of these outcomes were examined using two separate latent growth models. Recent history of self-injurious behaviors and demographics were tested as predictors of trajectories using a taxonomic approach. Overall, suicidal ideation and depressive symptoms declined over the course of care. Sex, history of self-injury, and sexual identity were associated with variability in one or both trajectories of change. Results suggest individual variability in the rate of change among youth in PHPs. Such information may be used to aid in treatment planning and quality improvement efforts within PHPs.

Determinants and Outcomes of Suicidal Behavior Among Patients With Major Depressive Disorder

Major depressive disorder (MDD) is an important risk factor of suicidal behavior, but the added burden of suicidal behavior and MDD on the patient and societal level, including all-cause mortality, is not well studied. Also, the contribution of various prognostic factors for suicidal behavior has not been quantified in larger samples. To describe the clinical and societal outcomes, including all-cause mortality, of suicidal behavior in patients with MDD and to explore associated risk factors and clinical management to inform future research and guidelines. This population-based cohort study used health care data from the Stockholm MDD Cohort. Patients aged 18 years or older with episodes of MDD diagnosed between January 1, 2012, and December 31, 2017, in any health care setting were included. The dates of the data analysis were February 1 to November 1, 2022. Patients with MDD with and without records of suicidal behavior. The main outcome was all-cause mortality. Secondary outcomes were comorbid conditions, medications, health care resource utilization (HCRU), and work loss. Using Region Stockholm registry variables, a risk score for factors associated with suicidal behavior within 1 year after the start of an MDD episode was calculated. A total of 158 169 unipolar MDD episodes were identified in 145 577 patients; 2240 (1.4%) of these episodes, in 2219 patients, included records of suicidal behavior (mean [SD] patient age, 40.9 [18.6] years; 1415 episodes [63.2%] in women and 825 [36.8%] in men). A total of 11 109 MDD episodes in 9574 matched patients with MDD without records of suicidal behavior were included as controls (mean [SD] patient age, 40.8 [18.5] years; 7046 episodes [63.4%] in women and 4063 [36.6%] in men). The all-cause mortality rate was 2.5 per 100 person-years at risk for the MDD-SB group and 1.0 per 100 person-years at risk for the MDD-non-SB group, based on 466 deaths. Suicidal behavior was associated with higher all-cause mortality (hazard ratio, 2.62 [95% CI, 2.15-3.20]), as well as with HCRU and work loss, compared with the matched controls. Patients with MDD and suicidal behavior were younger and more prone to have psychiatric comorbid conditions, such as personality disorders, substance use, and anxiety, at the start of their episode. The most important factors associated with suicidal behavior within 1 year after the start of an MDD episode were history of suicidal behavior and age, history of substance use and sleep disorders, and care setting in which MDD was diagnosed. This cohort study's findings suggest that high mortality, morbidity, HCRU, and work loss associated with MDD may be substantially accentuated in patients with MDD and suicidal behavior. Use of medication aimed at decreasing the risk of all-cause mortality during MDD episodes should be systematically evaluated to improve long-term outcomes.

Non-lethal suicidal behavior in university students of Spain during COVID-19.

Suicide is the fourth external cause of death in the world, in persons between the ages of l5 and 29. The objectives of this study were to measure the prevalence of suicidal behavior in university students and analyze the relationship of suicide risk with psychological distress, resilience, and family and social support. An observational and transversal study wherein the students at the University of Malaga (Spain) completed an online questionnaire which included items from different scales, sociodemographic and academic questions, and the subjective impact of the COVID-19 pandemic. Descriptive analyses and prevalence rates of suicidal behavior were calculated, and bivariate analyses, multiple linear regression, and a mediation and moderation analyses were conducted. A total of 2,212 students completed the questionnaire. The prevalence of the last 6 months was 30.4% wishing for death, 14.7% suicidal ideation, 5% self-harm injuries, and 0.5% suicide attempts. Psychological distress, family and social support were linked to the risk of suicide. Lastly, resilience and family support measure and moderate the relation between psychological stress and suicide risk. Psychological distress is a risk factor for suicidal behavior, while resilience and family and social support are linked to a lower risk of suicide.

Neurocognitive Suicide and Homicide Markers in Patients with Schizophrenia Spectrum Disorders: A Systematic Review.

Suicide and homicide are considered important problems in public health. This study aims to identify the cognitive performance of suicidal and homicidal behaviors in people with schizophrenia spectrum disorders, as well as examining whether there are shared neuropsychological mechanisms. A systematic review of the recent literature was carried out from September 2012 to June 2022 using the Medline (via PubMed), Scopus, Embase, and Cochrane databases. Among the 870 studies initially identified, 23 were finally selected (15 related to suicidal behaviors and 8 to homicidal behaviors). The results evidenced a relationship between impairment of cognitive performance and homicidal behavior; meanwhile, for suicidal behaviors, no consistent results were found. High neuropsychological performance seems to act as a protective factor against violent behavior in people with schizophrenia spectrum disorders, but not against suicidal behavior; indeed, it can even act as a risk factor for suicidal behavior. To date, there is insufficient evidence that shared neurocognitive mechanisms exist. However, processing speed and visual memory seem to be affected in the presence of both behaviors.

Smaller cornu ammonis (CA3) as a potential risk factor for suicidal behavior in mood disorders

Mood disorders and suicidal behavior have moderate heritability and familial transmission, and are associated with smaller hippocampal volumes. However, it is unclear whether hippocampal alterations reflect heritable risk or epigenetic effects of childhood adversity, compensatory mechanisms, illness-related changes, or treatment effects. We sought to separate the relationships of hippocampal substructure volumes to mood disorder, suicidal behavior, and risk and resilience to both by examining high familial risk individuals (HR) who have passed the age of greatest risk for psychopathology onset. Structural brain imaging and hippocampal substructure segmentation quantified Cornu Ammonis (CA1-4), dentate gyrus, and subiculum gray matter volumes in healthy volunteers (HV, N = 25) and three groups with one or more relatives reporting early-onset mood disorder and suicide attempt: 1. Unaffected HR (N = 20); 2. HR with lifetime mood disorder and no suicide attempt (HR-MOOD, N = 25); and 3. HR with lifetime mood disorder and a previous suicide attempt (HR-MOOD + SA, N = 18). Findings were tested in an independent cohort not selected for family history (HV, N = 47; MOOD, N = 44; and MOOD + SA, N = 21). Lower CA3 volume was found in HR (vs. HV), consistent with the direction of previously published findings in MOOD+SA (vs. HV and MOOD), suggesting the finding reflects a familial biological risk marker, not illness or treatment-related sequelae, of suicidal behavior and mood disorder. Familial suicide risk may be mediated in part by smaller CA3 volume. The structure may serve as a risk indicator and therapeutic target for suicide prevention strategies in high-risk families.

A Suicide-Specific Diagnosis – The Case For

A Suicide-Specific Diagnosis – The Case For

Suicide in adolescents: A case study

Suicidal behavior is the most violent behavior that a person commits against himself. Suicidal behavior is a complex form of behavior in which biological, psychological, cultural, environmental and social factors are effective together, which deeply affect the individual, his environment, society and subsequent generations. The etiology of suicidal behavior in adolescents includes problems such as psychiatric illness, domestic violence and restlessness, mental disorders, social events, previous suicide attempts, loss of family relatives, parental divorce, physical and/or sexual abuse, and substance use. Suicide attempt in children and adolescents; emerges as a growing public health problem. In this study, it was aimed to investigate the risk factors of suicidal behavior in adolescents and to examine the case sample. According to the results of the research, the presence of existing depressive symptoms before the Z.D. suicide attempt, previous suicide attempts, being in adolescence, having acute stresses, etc. Presence of risk factors such as suicide, loss of a lover, having a family history of suicide and being alone in the suicide attempt suggest that Z.D. is the trigger. In the presence of risk factors that increase the risk of suicide, it is important to recognize the triggers in advance and to plan an intervention.

The association between suicidal behaviour and violence, sexual abuse, and parental substance abuse among Sami and Greenlandic adolescents: the WBYG study and the NAAHS.

For young Indigenous people, suicide is one of the leading causes of death, and high rates in Arctic areas indicate serious health and societal concerns. More knowledge is needed, as suicidal behaviour predicts later death by suicide. The aim of this study was to investigate associations between suicidal thoughts and suicide attempts and negative life events, including violence, sexual abuse, and parental substance abuse, in Sami and Greenlandic adolescents, within and between groups and gender. Working samples included 442 Sami and 399 Greenlandic Inuit (15-16-year-olds), in The Norwegian Arctic Adolescent Health Study (NAAHS) and the Well-Being among Youth in Greenland (WBYG) study. Multivariable logistic regression explored associations between suicidal behaviour and violence, sexual abuse, and parental substance abuse. Across Indigenous groups, suicidal thoughts and attempts were significantly associated with violence and sexual abuse. The association between suicidal behaviour; especially suicidal thoughts, and sexual abuse was significant and strong among Sami females. Sami and Inuit adolescents with a history of childhood violence reported significantly more suicide attempts; the strongest association was found among Sami males. To Sami and Greenlandic Inuit, the experiences of negative life events, such as violence or sexual abuse are significant risk factors for suicidal behaviour. Public health programmes and prevention strategies targeting youth mental health and suicide should be culturally sensitive and sensitive to gender differences in the association between negative life events and suicidal behaviour.

The Multi-dimensional Assessment of Suicide Risk in Chronic illness-20 (MASC-20): Development and validation

BackgroundWe developed and tested the psychometric properties of the Multi-dimensional assessment of suicide risk in chronic illness-20 (MASC-20), which assess suicidal behavior (SB), and its associated distress in chronic physical illness (CPI). MethodsItems were developed by incorporating inputs from patient interviews, a review of existing instruments, and expert consultations. Pilot testing with 109 patients and field testing with 367 patients with renal, cardiovascular, and cerebrovascular diseases were conducted. We analyzed Time (T) 1 data to select items and T2 data to examine psychometric properties. ResultsForty preliminary items were selected through pilot testing; 20 were finalized from field testing. Optimal internal consistency (α = 0.94) and test-retest reliability (Intra class correlation coefficient = 0.92) of the MASC-20 supported reliability. Good fit of the four-factor model (physical distress, psychological distress, social distress, and SB) from exploratory structural equation modeling demonstrated factorial validity. Its correlations with MINI suicidality (r = 0.59) and the Schedule of Attitudes Toward Hastened Death-abbreviated scores (r = 0.62) indicated convergent validity. Higher MASC-20 scores in patients with clinical levels of depression and anxiety and low health status demonstrated known-group validity. The MASC-20 distress score predicted SB beyond known SB risk factors, supporting incremental validity. A cutoff score of 16 was optimal for identifying suicide risk. The area under the curve was within a moderately accurate range. The sum of sensitivity and specificity (1.66) indicated diagnostic utility. LimitationsMASC-20's applicability to other patient populations and its sensitivity to change requires testing. ConclusionsThe MASC-20 appears to be a reliable and valid tool for assessing SB in CPI.

Treatment outcomes after screening positive for suicidal ideation in United States military veterans

Suicidal ideation is a significant risk factor for suicidal behaviors, precipitating increased levels of clinical assessment and concern. The purpose of the current study was to determine if screening positive for ideation significantly predicted treatment outcomes in a non-VHA veteran population. Participants were military veterans seen at a Cohen Veterans Network clinic between January 1, 2016, and December 31, 2021. Of 12,178 episodes of care, 673 (5.5%) were positive screens (moderate or high risk on the C-SSRS) and 234 (1.9%) were high risk. Overall, a positive screen was not a significant predictor of the reason for discharge or whether it was planned or unplanned. However, meeting the criteria for being high risk was associated with negative treatment outcomes in terms of the reason for discharge and the planned or unplanned nature of the discharge. These findings emphasize the significance of stratifying suicide risk as well as the advantages of routinely gathering data on reasons for client discharge.

Metacognitions about suicidal thoughts

BackgroundRumination about suicide has recently been identified as a risk factor for suicidal behavior. According to the metacognitive model of emotional disorders, the activation and maintenance of rumination is dependent on specific metacognitive beliefs. On this background, the current study is concerned with the development of a questionnaire to assess suicide-specific positive and negative metacognitive beliefs. MethodsFactor structure, reliability and validity of the Scales for Suicide-related Metacognitions (SSM) were investigated in two samples comprised of participants suffering from lifetime suicide ideation. Participants of sample 1 (N = 214; 81.8% female; Mage = 24.9, SDage = 4.0) took part in a single assessment using an online survey. Participants of sample 2 (N = 56; 71.4% female; Mage = 33.2, SDage = 12.2) took part in two online assessments within a two week time-period. To establish convergent validity questionnaire-based assessments of suicidal ideation, general and suicide specific rumination and depression were used. Furthermore, it was analyzed whether suicide-related metacognitions predict suicide-specific rumination cross-sectionally and prospectively. ResultsFactor analyses revealed a two-factor structure of the SSM. Results indicated good psychometric properties, and provided evidence for construct validity and stability of the subscales. Positive metacognitions predicted concurrent and prospective suicide-specific rumination beyond the effect of suicide ideation and depression and rumination predicted concurrent and prospective negative metacognitions. ConclusionTaken together the results provide initial evidence that the SSM is a valid and reliable measure of suicide-related metacognitions. Furthermore, findings are in line with a metacognitive conceptualization of suicidal crises and provide first indications of factors that might be relevant for the activation and maintenance of suicide-specific rumination.

Psychiatric comorbidity profiles among suicidal attempters: A cohort study

IntroductionMore than 700,000 people die by suicide in 2019 globally (World Health Organitation 2021). Mental health problems constitute a risk factor for suicidal behavior and death by suicide (Hoertel et al. Mol Psychiatry 2015; 20 718–726). Different mental disorders have been related to different forms of suicidal ideation and behavior (Conejero et al. Curr Psychiatry Rep 2018; 20, 33) (Quevedo et al. Compr Psychiatry 2020; 102 152194). However, little is known on comorbidity profiles among suicide attempters.ObjectivesThe aim of our work was to identify the psychiatric comorbidity profiles of individuals who were admitted a hospital emergency department due to a suicide attempt. Moreover, it intended to know their clinical characteristics according to comorbidity profile.MethodsA sample of 683 attempters (71.30% female; M age= 40.85, SD= 15.48) from the SURVIVE study was used. Patients were assessed within the 15 days after emergency department admission. Sociodemographic (i.e., sex, age, marital status and employment status) and clinical data were collected. The International Neuropsychiatric Interview (MINI) was used to assess DSM-V Axis 1 mental health diagnoses and the Columbia Suicide Rating Scale (C-SSRS) to assess suicidal ideation and behavior. The Acquired Capacity for Suicide-Fear of Death Scale (ACSS-FAD), the Patient Health Questionnaire (PHQ-9) to assess the frequency of depressive symptoms during the past 2 weeks, and the General Anxiety Disorder-7 (GAD-7) scale to assess symptoms of worry and anxiety were also conducted. For the identification of comorbidity profiles, latent class analysis framework was followed considering diagnosis to each individual disorder as clustering variables. On the other hand, binary logistic regression was used to study the relationship between comorbidity profile membership and clinical factors.ResultsTwo classes were found (Class I= mild symptomatology class, mainly featured by emotional disorder endorsement; and Class II= high comorbidity class, featured by a wide amount of endorsed diagnoses) (see figure 1). Individuals from the High comorbidity class were more likely to be female (OR= 0.98, p&lt;.05), younger in age (OR= 0.52, p&lt; .01), with more depressive symptoms (OR=1.09, p&lt;.001) and have greater impulsivity (OR= 1.01, p&lt;.05).Image:ConclusionsWe found two profiles of people with suicidal behavior based on the presence of mental disorders. Each of the suicidal subtypes had different associated risk factors. They also had a different profile of suicidal behavior.Disclosure of InterestNone Declared
