Predictors Of Suicidal Ideation Research Articles

Comparison of the factors for suicidal ideation and suicide attempt: a comprehensive examination of stress, view of life, mental health, and alcohol use.

This study was performed to examine the elements that cause suicidal ideation to develop into a suicide attempt by comparing the factors related to suicidal ideation and attempt. The subjects in the study were 5982 employees, who received mental health screening from January 2016 to December 2019 in Korea. Multivariate binary logistic regression analysis was performed with suicidal ideation and suicide attempt as dependent variables respectively. While suicidal ideation was associated with both moderate and severe grades of depression and alcohol consumption, only severe grades of depression and alcohol consumption were associated with suicide attempts. Among family, interpersonal, work-related, and financial stress, which were significant predictors of suicidal ideation, only family stress predicted suicide attempts. Whereas dissatisfaction with the present, regret for the past, and hopelessness for the future were all predictors for suicidal ideation, only regret for the past was a significant predictor of suicide attempts. The distinctive impact of family stress on suicide attempts suggests that family support can play a pivotal role in suicide prevention, and the significant impact of regret for the past on suicide attempts indicates the need for a cognitive approach ina high-risk population. Finally, the substantial impact of alcohol on suicide attempts compared to suicidal ideation suggests the importance of alcohol regulation in suicide prevention.

Clarifying the association of eating disorder features to suicide ideation and attempts.

We examine the relationships of eight eating disorder (ED) features to histories of suicide ideation and suicide attempts. Participants were 387 adults (62% female, mean age = 36 years) recruited via an online platform, and oversampled for the presence of ED features, who completed standardized self-report measures of study variables. Different ED features predicted suicide ideation versus attempts. Specifically, Restrictive Eating (d = 0.44), Purging (d = 0.30), and Body Dissatisfaction (d = 0.27) were higher among ideators compared to nonsuicidal participants. In contrast, Muscle Building (d = 0.31), Excessive Exercise (d = 0.26), Cognitive Restraint (d = 0.23), and Restrictive Eating (d = 0.20) were higher among attempters compared to ideators-however, we note that the p-values for these effects range between 0.02 and 0.04 and it is unclear if they would replicate. Independent replication is important. Findings have implications for the conceptualization of suicide risk in individuals with EDs.

Suicidal Ideation in Bipolar Disorder: The Relation with Clinical and Sociodemographic Variables.

Bipolar disorder (BD) has the highest risk of suicide among all mental disorders. Thus, identifying factors related to suicidal ideation is essential for a better assessment of the risk of suicide in BD. To analyze the relationship between suicidal ideation and clinical and sociodemographic characteristics in BD patients. This is a cross-sectional study that included eighty individuals with BD. Information regarding sociodemographic data and history of attempted suicide were collected, and the Hamilton Depression Scale, Young Mania Rating Scale, Positive And Negative Syndrome Scale/positive symptom subscale, Clinical Global Impressions Scale for use in bipolar illness, Insight Scale for Affective Disorders, and Barratt Impulsiveness Scale were administered. The presence and severity of suicidal ideation were assessed using the Beck Scale for Suicidal Ideation. All regression models significantly predicted suicidal ideation. In the model that had the lowest AIC score and the highest cross-validity, the severity of depressive and of manic symptoms (standardized β = 0.49, p < 0.001; standardized β = 0.42, p = 0.007), the insight level (standardized β = - 0.38, p = 0.012) and previous suicide attempt (standardized β = 0.20, p = 0.036) acted as predictors of suicidal ideation, while degree of impulsivity (β standardized = 0.13, p = 0.229) and educational level (standardized β = - 0.16, p = 0.108) did not give a significant contribution. According to our results, more severe depression and mania symptoms, higher level of insight and a history of suicide attempt indicate the occurrence of suicidal ideation in BD.

Modifiable predictors of suicidal ideation during psychotherapy for late-life major depression. A machine learning approach

This study aimed to identify subgroups of depressed older adults with distinct trajectories of suicidal ideation during brief psychotherapy and to detect modifiable predictors of membership to the trajectories of suicidal ideation. Latent growth mixed models were used to identify trajectories of the presence of suicidal ideation in participants to a randomized controlled trial comparing Problem Solving Therapy with “Engage” therapy in older adults with major depression over 9 weeks. Predictors of membership to trajectories of suicidal ideation were identified by the convergence of four machine learning models, i.e., least absolute shrinkage and selection operator logistic regression, random forest, gradient boosting machine, and classification tree. The course of suicidal ideation was best captured by two trajectories, a favorable and an unfavorable trajectory comprising 173 and 76 participants respectively. Members of the favorable trajectory had no suicidal ideation by week 8. In contrast, members of the unfavorable trajectory had a 60% probability of suicidal ideation by treatment end. Convergent findings of the four machine learning models identified hopelessness, neuroticism, and low general self-efficacy as the strongest predictors of membership to the unfavorable trajectory of suicidal ideation during psychotherapy. Assessment of suicide risk should include hopelessness, neuroticism, and general self-efficacy as they are predictors of an unfavorable course of suicidal ideation in depressed older adults receiving psychotherapy. Psychotherapeutic interventions exist for hopelessness, emotional reactivity related to neuroticism, and low self-efficacy, and if used during therapy, may improve the course of suicidal ideation.

Evaluation of suicidal ideation in adult people with epilepsy and caregivers in a tertiary center

Epilepsy is a risk factor for suicidal ideation (SI). SI still poorly investigated in caregivers of people with epilepsy (PWE). We aimed to analyze the prevalence and predictors of SI in adults PWE and caregivers.

The Changes and the Predictors of Suicidal Ideation Among HIV-positive Sexual Minority Men: A Five-year Longitudinal Study from China

This study aimed to explore whether there were differences in suicidal ideation at different time points among sexual minority men (SMM) within five years of HIV diagnosis, and to investigate the influence of time and psychosocial variables on suicidal ideation. This was a five-year follow-up study focusing on the suicidal ideation among HIV-positive SMM who were recruited when they were newly diagnosed with HIV. Suicidal ideation and psychosocial characteristics including depression, anxiety, HIV-related stress, and social support were assessed within one month, the first year, and the fifth year after HIV diagnosis. A total of 197 SMM newly diagnosed with HIV completed three-time point surveys in this study. The prevalence of suicidal ideation was 27.4%, 15.7%, and 23.9% at one month, the first year, and the fifth year after HIV diagnosis, respectively. The risk of suicidal ideation was lower in the first year than baseline, but there was no significant difference between the fifth year and baseline. Emotional stress and objective support independently predicted suicidal ideation and they had interactions with time. The suicidal ideation of SMM newly diagnosed with HIV decreased in the first year and then increased in the fifth year, not showing a sustained decline trend in a longer trajectory of HIV diagnosis. Stress management, especially long-term stress assessment and management with a focus on emotional stress should be incorporated into HIV health care in an appropriate manner. In addition, social support should also be continuously provided to this vulnerable population.

Factors associated with suicidal ideation in drug addicts based on the theory of planned behavior

BackgroundSeveral studies have attempted to understand the link among drug addicts and suicidal ideation. The purpose of this study was to investigate the factors associated with suicidal ideation in drug addicts based on the Theory of Planned Behavior (TPB).MethodThis cross-sectional study was conducted with 2160 of drug addicts in private and public clinics for quitting addiction through methadone treatment in Shiraz city, Fars province, Iran from October 2018 to June 2019. Data gathering tools were a questionnaire on demographic characteristics, the Beck Scale for Suicidal Ideation and a questionnaire based on constructs of TPB. Data were analysed by SPSS 22 using descriptive statistics (mean, standard deviation, and frequency) and statistical tests (independent t-test, Pearson correlation coefficient, and linear regression). The significance level was considered 0.05.ResultsThe mean age of the participants was 39.24 ± 11.92; 80.28% of them had a history of quit and 43.19% of them had a history of arrest and imprisonment. According to the results, 19.63% of the participants had suicidal ideation and 10.97% had a history of suicide attempt during their lifetime. The constructs of attitude, subjective norms, perceived behavioral control, and intent predicted suicidal ideation in the subjects. Intent and perceived behavioral control constructs were the strongest predictors of suicidal ideation, respectively. In general, the studied variables predicted 54.8% of suicidal ideation.ConclusionThe structures of attitude, subjective norms and perceived behavioral control and intent predicted suicidal ideation in the drug addicts, so the theory of planned behavior will be a good framework for educational interventions to reduce suicide in them.

Being certain that negative events will happen or that positive events will not happen: Depressive predictive certainty and change in suicide ideation over time.

Relatively little research has examined the precise components of hopelessness that increase vulnerability to suicidal thinking. We examined whether certainty about an absence of positive future outcomes (Certainty-AP) would more strongly predict suicide ideation over time than certainty about negative future outcomes (Certainty-N). Young adults (N=208), ages 18-34 (M=19.08, SD=2.22), with either recent suicide ideation, suicide attempt history, or past-year psychiatric diagnosis were assessed four times over 18months. We used multilevel modeling to assess within-participant differences in suicide ideation over time. Both Certainty-AP and Certainty-N predicted later suicide ideation above and beyond generalized hopelessness and depressive symptoms, when examined in separate models. However, Certainty-AP emerged as a stronger predictor of suicide ideation than Certainty-N when examined in the same model. These findings suggest that certainty about an absence of positive future outcomes may have a more unique prospective relationship to SI than certainty about the presence of negative future outcomes. We discuss clinical and theoretical implications of these findings.

Psychometric Properties of Interpersonal Needs Questionnaire-15 for Predicting Suicidal Ideation among Migrant Industrial Workers in China.

Objective: Interpersonal theories of suicide suggest that the Interpersonal Needs Questionnaire (INQ) can be used to measure suicidal ideation, but few studies have focused on migrant people, a group with a high prevalence of suicidal ideation. The aim of this study was to validate the psychometric properties of the INQ-15 and its prediction of suicidal ideation among migrant industrial workers in China. Method: A stratified multi-stage sample of 2023 industrial workers was recruited from 16 factories in Shenzhen, China. There were 1805 nonlocal workers, which we defined as migrant workers with a mean age of 32.50 ± 8.43 years old who were 67.3% male. The structure of the Chinese version of the INQ-15 and its correlation and predictive utility for suicidal ideation were examined through factor analysis, the Item Response Theory, the M2 test, logistic regression, and receiver operating characteristic (ROC) analysis. Results: Different from studies among various samples in which a two-factor solution is identified, results within this sample indicated three factors: perceived burdensomeness, thwarted belongingness, and social isolation. The model fit statistics of three-factor INQ were 0.075 for RMSEA, 0.945 for CFI, 0.932 for TLI, and 0.067 for SRMR. The model standard estimated factor loadings ranged from 0.366 to 0.869. The summed scores of INQ and perceived burdensomeness predicted suicidal ideation after controlling for sociodemographic characteristics such as age, gender, and income with AUC of 0.733 (95% CI: 0.712/0.754) and 0.786 (95% CI: 0.766/0.804). In the meantime, the comparison of the predictive ability between INQ total scores and PB scores was significant with p < 0.05. Conclusion: The INQ has good psychometric properties and can be used to assess how migrant workers living in the Shenzhen perceive meeting interpersonal psychological needs and shows good predictive ability of suicidal ideation. Perceived burdensomeness appears to play a role in suicide and may be a point of intervention, yet the notable deviation from previous findings and the relative weakness of two of the other factors warrant further study.

Functional gastrointestinal disorders as predictors of suicidal ideation. An observational study.

Suicidal ideation (SI), a symptom of depression, is known to be associated with irritable bowel syndrome (IBS) but is not known to be associated with other functional gastrointestinal disorders (FGIDs). However, the source of this association is discussed. It could be related to a possible abnormal biochemical pathway implicating neurotransmitters common to both disorders like serotonin or pain and an ill-being associated with a chronic disorder of unknown etiology. The present study aims to search for the FGIDs associated with suicidal ideation. Observational study. A total of 1469 patients with FGIDs (71% of women) were included in the present study. They filled the Rome III questionnaire, Beck depression inventory, and state and trait anxiety questionnaires. Data were analyzed using analysis of variance with Bonferroni correction and logistic regression analysis. Suicidal ideation was reported by 15% of patients, associated with increased scales of depression (P < 0.001), state (P = 0.006), and trait anxiety (P = 0.021). Clinically, these patients reported a higher prevalence of IBS-diarrhea subtype (P = 0.045), fecal incontinence (P = 0.020), soiling (P = 0.016), and difficult defecation (P = 0.005), and higher perceived severity for constipation, diarrhea, bloating, and abdominal pain (P < 0.001 for all scales). This study shows that only functional bowel and functional anorectal disorders are associated with suicidal ideation. This result must be taken into account in the management of these patients.

Suicidal ideation in LGBT youth: a literature review

A review of the literature on experiences and meanings surrounding suicide ideation in LGBT youth was conducted. It was found that a large part of the studies were carried out in Anglo-Saxon populations that tended to compare "heteronormative" with "non-heteronormative" populations, through eminently quantitative designs, where the main results were greater vulnerability in comparison to the heterosexual population, internalized homophobia and rejection of one's own sexual orientation. Social and family vulnerability that fed the experience of diverse violence in different areas of their lives. In addition, alcohol and drugs were predictors of suicidal ideation. These living conditions favored mood disturbances and affected mental health, as well as a tendency to develop self-injurious behaviors. However, family and social support were protective against suicidal ideation. Few authors used the recognized categories within the LGBT community to describe their participants, the category most commonly used was "non-heteronormative population", tending to reproduce heterosexist models. Most of the papers on experiences and meanings did not give their participants a voice.

Predicting Suicide Ideation and Psychological Helplessness based on Domestic Violence in Women

Predicting Suicide Ideation and Psychological Helplessness based on Domestic Violence in Women

Social Factors as Predictors of Suicide Ideation Among Police Officers in Police Training Schools in the South-South Geopolitical Zone of Nigeria: Educational Implications

The study investigated social factors (perception of corruption and domestic pressure) as predictors of suicide ideation among Police Officers in Police Training Colleges in the South-South Geopolitical Zone of Nigeria. Two research questions were raised and two hypotheses tested at 0.05 level of significance. A sample size of 3,373 Police Officers in training in four Police Training Colleges in the South-South Geopolitical Zone of Nigeria was randomly selected through simple random sampling technique. Multiple Prediction Design of Correlational Research Method was used for the investigation, while Linear Regression was used for the entire analyses and hypotheses testing. The result showed that there is a significant relationship between psychological factors (corruption and domestic pressure) and suicide ideation of Police Officers in Police Training Colleges; also the result showed that there is a very positive relationship between perception of corruption and domestic pressure as predictors of suicide ideation among Police Officers in Training Colleges in the South-South Geopolitical Zone of Nigeria. The result also suggests that among other variables, corruption and domestic pressure are some of the predictive variables of suicide ideation. Recommendations were made.

Exposure to violence, polyvictimization and youth's mental health and alcohol use in El Salvador

BackgroundCommunity and family violence are major global health problems. Approximately 1.3 million deaths around the world and 2.5% of global mortality are due to violence. In El Salvador, youth are exposed to multiple levels of physical and emotional violence, abuse, and crime. ObjectiveThe objective of this study was to investigate the various sources of violence against youth and determine the associations with mental distress symptoms, suicidal ideation, and alcohol use outcomes. Participants and settingWe use information gathered in 2017 from a representative sample of 13- to 24-year-old adolescents and young adults from El Salvador. MethodsData used in this analysis came from a nationally cross-sectional household survey called Violence Against Children Survey (VACS) in El Salvador. We used logistic regression models to determine the associations between lifetime witnessing violence, exposure to physical, sexual, emotional violence, and youth mental health outcomes. ResultsPolyvictimization was associated with greater odds of each mental health outcome after adjusting for confounders. The strongest relative association was observed between emotional violence and mental distress. Sexual violence and emotional violence were predictors of suicidal ideation. Finally, physical violence and sexual violence were associated with alcohol use. The greatest associations were observed between sexual violence perpetrated by a parent, peer, or another adult in the community and suicidal ideation, at a magnitude of approximately six times higher odds. ConclusionsPreventing violence against youth is likely to improve mental health and wellbeing in El Salvador and other similar contexts worldwide.

Racial Associations Between Gambling and Suicidal Behaviors Among Black and White Adolescents and Young Adults.

Suicide is the second leading cause of death among Black youth ages 10-19 years. Between 1991 and 2017, rates of suicide among Black youth have been increasing faster than rates among any other race/ethnic group. There are many factors that may explain this increase, with gambling being suggested as one such potential risk factor. This review examines the association between gambling and suicide behaviors, and how these associations may vary between Black and White youth and young adults. The current review examines these associations using data from the Missouri Family Study (MOFAM). Recent findings have revealed distinct patterns of substance use initiation and gambling behaviors between Black youth and White youth. While strong links between gambling and suicide behaviors have also been reported, whether the associations were consistent across race/ethnicity groups was not investigated, nor in these cross-sectional analyses was it possible to determine whether the gambling behaviors preceded or followed suicidality. Thus, there is a need to investigate whether there are differences in the associations of gambling and suicide behaviors at the race/ethnicity level in tandem with data that examine the sequence of the behaviors. The current report focuses on racial/ethnic differences using data that allow for sequencing the occurrence of the behaviors via the age of first gambling experience, and of first suicidal symptom, to better distinguish the nature of the association. The current findings revealed that gambling initiation predicted suicide ideation among Black youth, while no significant association was found among White youth. This is of major public health concern, given the rising rates of suicide among Black youth, and the increased availability of gambling. The report did not find a link between gambling and suicide attempts. Culturally tailored interventions should be considered among schools, families, and clinicians/providers, to highlight the risk of adolescent gambling, particularly among Black youth.

Prediction of suicidal ideation and attempt in 9 and 10 year-old children using transdiagnostic risk features.

The objective of the current study was to build predictive models for suicidal ideation in a sample of children aged 9–10 using features previously implicated in risk among older adolescent and adult populations. This case-control analysis utilized baseline data from the Adolescent Brain and Cognitive Development (ABCD) Study, collected from 21 research sites across the United States (N = 11,369). Several regression and ensemble learning models were compared on their ability to classify individuals with suicidal ideation and/or attempt from healthy controls, as assessed by the Kiddie Schedule for Affective Disorders and Schizophrenia–Present and Lifetime Version. When comparing control participants (mean age: 9.92±0.62 years; 4944 girls [49%]) to participants with suicidal ideation (mean age: 9.89±0.63 years; 451 girls [40%]), both logistic regression with feature selection and elastic net without feature selection predicted suicidal ideation with an AUC of 0.70 (CI 95%: 0.70–0.71). The random forest with feature selection trained to predict suicidal ideation predicted a holdout set of children with a history of suicidal ideation and attempt (mean age: 9.96±0.62 years; 79 girls [41%]) from controls with an AUC of 0.77 (CI 95%: 0.76–0.77). Important features from these models included feelings of loneliness and worthlessness, impulsivity, prodromal psychosis symptoms, and behavioral problems. This investigation provided an unprecedented opportunity to identify suicide risk in youth. The use of machine learning to examine a large number of predictors spanning a variety of domains provides novel insight into transdiagnostic factors important for risk classification.

The Moderating Role of Stress Response on the Relationship Between Subjective Sleep Quality and Suicide Ideation in Adolescence

Objective Problems sleeping and stress are known to contribute to the development of suicide ideation. However, it is unclear how these risk factors interact longitudinally. The purpose of this study was to determine the impact of problems sleeping on the development of suicide ideation in adolescence one year later and how the relationship changes with the addition of stress as a moderator. Method Data were collected from 153 adolescents (M age = 12.8, SD = 1.6) over three years as part of a larger study. Participants completed the MINI-Kid and Youth Self-Report, which were used to assess for suicidality. The Stress scale of the YSR was used to measure stress. Participants also completed the Adolescent Sleep Wake Scale, which was used to assess their perceptions of their sleep quality. Results Logistic moderation analyses demonstrated a significant interaction between ASWS and YSR Stress in the prediction of suicide ideation one year later, Wald χ 2(1)=4.57, OR = 0.68, p < 0.05. Results demonstrated higher odds of endorsing SI as stress increased when sleep quality was poor (OR = 21.51) compared to when sleep quality was high (OR = 4.03), suggesting that adequate sleep may act as a protective factor against suicide ideation. Conclusions The results are indicative of long-term consequences of sleep on adolescent mental health, particularly when faced with high levels of stress. These results may have significant clinical implications for suicide prevention efforts as this relationship may help identify at-risk adolescents prior to the initial experience of suicide ideation.

Inflexible Interpretations of Ambiguous Social Situations: A Novel Predictor of Suicidal Ideation and the Beliefs That Inspire it

Suicidal ideation has been linked to a bias toward interpreting ambiguous information in consistently less positive/more negative manners (“positive/negative interpretation bias”), implying that information processing biases might distort beliefs thought to inspire suicidal ideation (e.g., those regarding burdensomeness). The present study therefore examined whether suicidal ideation and beliefs highlighted in theories of suicide are related to positive/negative interpretation bias and/or a bias against revising negative interpretations in response to evidence against them (“negative interpretation inflexibility”).

European Depression Polygenic Risk Score Predicts Suicide Behavior in Mexicans

Depression is frequently linked to suicide behaviors (ideation, plan, and attempt). To date, the association between the Major Depressive Disorder Polygenic Risk Score (MDD-PRS) and suicide behaviors (SB) has been primarily examined in individuals of European ancestry. Nonetheless, the extent to which MDD-PRS can predict SB in populations with a different ethnicity (Mexicans) remains unclear. The current study aimed to assess whether MDD-PRS predict suicide ideation, planning, and attempt in a sample of young Mexican individuals.

Inflexible Interpretations of Ambiguous Social Situations: A Novel Predictor of Suicidal Ideation and the Beliefs That Inspire It

Suicidal ideation has been linked to a bias toward interpreting ambiguous information in consistently less positive or more negative manners ( positive/negative interpretation bias), implying that information-processing biases might distort beliefs thought to inspire suicidal ideation (e.g., those regarding burdensomeness). Therefore, in the present study, we examined whether suicidal ideation and beliefs highlighted in theories of suicide are related to positive/negative interpretation bias and/or a bias against revising negative interpretations in response to evidence against them ( negative interpretation inflexibility). Data were collected in three waves, each 1 week apart. Network analyses and structural equation models provided evidence that negative interpretation bias (cross-sectionally) and negative interpretation inflexibility (cross-sectionally and over time) were related to suicidal ideation and that the latter relationship was mediated by perceived burdensomeness. By identifying this mediation pathway in the present study, we provide a potential mechanism by which perceptions of burdensomeness, a key risk factor for suicidality, might arise and/or persist.
