Is suicidal behaviour a stronger predictor of later suicide than suicidal ideation? A systematic review and meta-analysis

It is time to dethrone suicidal ideations as a risk predictor

ObjectiveTo evaluate the practice of using reported suicidal ideations (SI) as an important predictor of suicide and as a major indicator to decide the eligibility and priority of access to mental health services.FindingsExamples on the widespread use of SI in triage, screening, and management protocols of mental health presentations, both in emergency and community settings, are presented. Such widespread use comes in contrast to the evidence clearly indicating the limited utility of SI as a suicide predictor. SI limitations are expected when put in the larger context of the generalized failure of suicide prediction tools. The potential detrimental effects of an exaggerated SI status on several aspects of the clinical encounter are discussed. Finally, potential systemic downsides in humanitarian and resource-limited settings are hypothesized, such as hindering mental health integration into primary care, as well as over-reporting of SI by beneficiaries seeking aid and vulnerability status.ConclusionsSI still holds a "canonical" status as a risk indicator and triage guide. This exaggerated status, in addition to lacking evidence, can also lead to potential downsides, especially in overloaded health systems.

The underlying dynamics of a suicidal ideation latent network model: The role of hopelessness, psychopathology, emotion regulation, and behavioral coping skills in adolescents from the general population

BACKGROUND

Suicide is a major cause of death among adolescents, with suicidal ideation (SI) being a common symptom in this group. SI arises from a complex mix of biological, environmental, and psychological factors, however, the specific relationships between them is not yet fully understood. Network theory has been proposed as a promising framework to analyze these relationships, with latent network models (LNM) offering a novel approach to capture their complex underlying dynamics.

METHODS

We examined a SI-based LNM in a sample of 1539 students from secondary public schools (M = 15.336; SD = 1.022; female = 52.39 %). The model included depressive and anxiety symptoms, feelings of hopelessness, emotion regulation strategies, and cognitive-behavioral and problem-solving skills. Strength and expected influence indices were calculated for each variable.

RESULTS

Hopelessness and depressive symptoms showed the highest strength and expected influence values within the model, respectively. Our findings suggest that hopelessness might play a crucial mediating role linking common mental disorders and emotion regulation strategies with SI in adolescents. Expressive suppression had a direct and negative association with SI, showing its underlying regulatory role when other factors are controlled. Cognitive-behavioral and problem-solving skills showed weak links with SI.

CONCLUSIONS

Primary care- and school-based interventions should center on hopelessness as a relevant direct predictor for SI, and potential mediator in the course of SI. A combination of research and intervention efforts directed at reducing hopelessness in youths may prove to be essential for reducing suicide-related behaviors altogether.

Examining the integrated model of the interpersonal-psychological theory of suicide and intersectionality theory among Black male adolescents

INTRODUCTION

Guided by Opara et al.'s (2022), Integrated Model of the Interpersonal Psychological Theory of Suicide and Intersectionality Theory, the current study examined contextual stressors experienced disparately by Black youth (racial discrimination, poverty, and community violence) as moderators of the association between individual motivating factors for suicidal thoughts and behaviors (perceived burdensomeness, thwarted belongingness, and hopelessness) and active suicidal ideation.

METHOD

Participants were 457 Black adolescent boys (mean age = 15.31, SD = 1.26) who completed self-report surveys.

RESULTS

As predicted, the association between perceived burdensomeness and active suicidal ideation was significantly moderated by economic stress. In addition, the association between peer belongingness and suicidal ideation was significantly moderated by racial discrimination, but there were no moderating effects for school belongingness. Finally, the association between hopelessness and suicidal ideation was significantly moderated by both racial discrimination and witnessing community violence.

CONCLUSION

These findings highlight the need for research, interventions, and policy work devoted to using integrated approaches of individual and socioeconomically relevant patterns of suicidal thoughts and behaviors to support Black youth exposed to various forms of structural oppression.

The Trend in Suicide Risk Among People with HIV Before, During, and After the COVID-19 Pandemic Lockdown

Suicide Risk (SR) and the COVID-19 pandemic affected People with HIV (PWH) disproportionately in comparison with the general population, but little information on SR during and after the COVID-19 lockdown on the Latino PWH has been described, therefore, this study aimed to describe SR in PWH attended the HIV clinic before (2018-2019), during (2020), and after (2021-2022) the COVID-19 lockdown, the trend of SR, and the factors associated. Three standardized questions from the "Columbia-Suicide Severity Rating Scale" (C-SSRS) were routinely applied as screening for suicide risk to all PWH attending their clinical visits during 2018-2022. We estimated suicidality risk and rate. We compared sociodemographic characteristics in those with and without SR. We evaluated the potential association of SR with the calendar year before, during, and after the COVID-19 lockdown using a mixed-effects logistic regression. A total of 2330 patients were seen during the study period; 2157 (93%) were evaluated for suicidality at least once, of those, 75 (3.5%) had SR. Those with SR compared with non-SR were more frequently women (20% vs 10%) and with a heterosexual HIV transmission route (29% vs 23%). SR rates per 1000 patients-day among those evaluated were 0.03 in 2018, 0.25 in 2019, 3.16 in 2020, 7.0 in 2021 and 11.98 in 2022. Throughout the model, independently of covariables, a significant increase in the OR of SR was observed in these years compared to 2018: 1.07 in 2019; 2.74 in 2021; and 4.82 in 2022, except in 2020, OR = 0.18.

Sleep-related drugs utilization and suicide behaviors: a population-based study in China

BACKGROUND

Previous studies have yielded conflicting findings regarding the relationship between the use of sleep-related drugs (SRDU) and suicidal behaviors. This population-based study aimed to analyze the associations between SRDU and suicidal behaviors. Additionally, we examined the associations between SRDU and specific conditional suicidal behaviors, providing insights into the impact of SRDU on the progression of suicidal behaviors.

METHODS

The study was conducted among community residents aged 18 and older using a cross-sectional design, analyzing 21,376 participants. Data on SRDU, suicidal ideation, plans, and attempts were collected. Participants were categorized into general individuals without suicidal behaviors (GNS), suicidal ideators without a plan or attempt (SINPA), suicidal ideators with a plan but no attempt (SIP), and individuals who attempted suicide (SA). Insomnia, sleep apnea, rapid eye movement sleep behavior disorder (RBD), and narcolepsy were assessed using the Athens Insomnia Scale, Berlin Questionnaire, Rapid Eye Movement Sleep Behavior Disorder Questionnaire, and Ullanlinna Narcolepsy Scale, respectively.

RESULTS

After adjusting for sociodemographic variables, insomnia, sleep apnea, RBD, and narcolepsy, SRDU showed a positive association with suicidal ideation (OR = 3.02), plans (OR = 4.78), and attempts (OR = 6.40; all p < 0.001). Compared to GNS, and after controlling for the same variables, SRDU was associated with SINPA (OR = 2.46), SIP (OR = 5.11), and SA (OR = 6.93; all p < 0.001) respectively. However, no significant differences in SRDU were found between SINPA, SIP, and SA (all p > 0.05).

CONCLUSIONS

This population-based study confirms that SRDU is positively associated with suicidal ideation, plans, and attempts, even after accounting for the risk factors of insomnia, sleep apnea, RBD, and narcolepsy. Nonetheless, SRDU does not appear to influence the progression from suicidal ideation to attempt.

The Prevalence of Suicidal Ideation According to Occupation and Other Employment Variables

Background: The literature is scant on the associations between employment-related variables and suicidal ideation. Aims: The objectives were to explore these associations in the national French working population. Methods: The study relied on two independent national French surveys and their samples of 22,420 workers (employees and self-employed workers) and 25,628 employees, respectively. Employment variables included occupation, economic activity of the company, public/private sector, company size, permanent/temporary work, full/part time, seniority, and employee/self-employed worker. Suicidal ideation was assessed using one item. The associations between employment variables and suicidal ideation were studied using bi- and multivariable weighted analyses (Rao-Scott Chi-2 test and logistic regression). Gender differences were explored and covariates were taken into account. Results: The associations between employment variables and suicidal ideation were mostly not statistically significant. Some differences in suicidal ideation between occupations and economic activities were difficult to interpret due to overlaps in the confidence intervals. The prevalence of suicidal ideation increased with seniority among employees. Limitations: The study design was cross-sectional. Conclusion: The studied employment variables may have little effect on suicidal ideation. As suicidal ideation is a risk factor for suicide, more research is needed to explore the work-related risk factors for suicide and suicidal ideation.

Incidence and antecedents of emergent suicidal ideation and behavior among Veterans with serious mental illness receiving intensive case management

Veterans with serious mental illness (SMI; i.e., schizophrenia-spectrum disorders, major mood disorders, post-traumatic stress disorder) are a high-risk group for suicide and little is known about those with emergent suicidal ideation and/or behavior. The primary study aim was to examine the six-month incidence and baseline antecedents of emergent suicidal ideation and/or behavior (suicidal ideation and/or behavior at six-month follow-up but not at enrollment) in Veterans with SMI enrolled in the Veterans Health Administration's (VHA) community-based treatment program (i.e., Intensive Community Mental Health Recovery [ICMHR]). A second, exploratory aim was to examine six-month follow-up ICMHR service use (e.g., frequency of contact with Veteran, type of services provided) in those with emergent suicidal ideation and/or behavior. National ICMHR program evaluation data from 2000 to 2013 were analyzed for Veterans with enrollment and six-month follow-up assessments (n = 9921). Analyses examined differences in baseline characteristics and ICMHR service use in those with emergent suicidal ideation and/or behavior compared to those with other suicidal ideation and/or behavior patterns (i.e., none [at either timepoint], improved [present at enrollment but not at follow-up], persistent [present at both timepoints]). Results showed that 1.7% (n = 167) of the sample had emergent suicidal ideation and/or behavior. Some suicidal ideation and/or behavior groups differed significantly from the emergent suicidal ideation and/or behavior group on odds of: lifetime hospitalizations, baseline subjective distress, affective disorder diagnosis, and baseline quality of life. Overall, historical and current clinical factors and quality of life should be assessed in this population given their association with emergent suicidal ideation and/or behavior.

Reframe-IT+, an indicated preventive school-based intervention, reduces suicidal ideation among adolescents in vulnerable contexts in Chile

BACKGROUND

Suicide prevention programs delivered in school settings have been shown to reduce suicide attempts and ideation among adolescents. School-based digital interventions targeting at-risk youth are a promising avenue for suicide prevention, and some evidence has shown that blending digital and face-to-face components may improve the effectiveness. However, further evidence is needed, especially in Latin America, where mental health support is limited. We tested the effectiveness of the Reframe-IT+, a blended cognitive behavioral indicated intervention to reduce suicidal ideation, designed to be delivered in school settings. It includes 13 sessions, combining eight internet-based sessions and five face-to-face sessions.

METHODS

We conducted a cluster RCT and delivered the Reframe-IT + among secondary students attending Years 9-11. We recruited 21 schools that were randomized into two groups: (1) Intervention Reframe-IT + Group (IG) (n = 863) and (2) Control Group (CG) (n = 683). All consented students completed online screening self-reported questionnaires at baseline. The primary outcome was suicidal ideation . Additionally, we tested the impact of the intervention on depressive and anxiety symptoms, hopelessness, and emotion regulatory strategies, including social solving-problems skills, behavioral activation, cognitive reappraisal, and emotion suppression. A total of 303 students (IG, n = 164; CG, n = 139) were identified as at risk and eligible for inclusion in the study. From those, 224 students (IG, n = 123; CG, n = 101) and their caregivers were interviewed to confirm inclusion and exclusion criteria. Finally, 48 and 47 students were allocated to control and intervention groups, respectively, and answered the online questionnaires at post-intervention. We performed an intention-to-treat analysis using repetitive measures and multilevel regression analyses.

RESULTS

We found a significant reduction in suicidal ideation (b=-6.7, p = 0.015, Cohen´s d = 0.49), depressive (b=-3.1, p = 0.002, Cohen´s d = 0.81) and anxiety (b=-2.60, p < 0.001, Cohen´s d = 0.72) symptoms, and hopelessness (b=-3.7, p < 0.001, Cohen´s d = 0.70) in the intervention group compared to the control group at post-intervention. We also found improvement in solving-problems skills (b=-1.6, p = 0.002, Cohen´s d = 0.58), behavioral activation (b = 2.8, p = 0.019, Cohen´s d = 0.47), and cognitive reappraisal (b = 2.2, p = 0.029, Cohen´s d = 0.53). In the exploration of the intervention mechanisms concerning suicidal ideation, the total indirect effect of the intervention (b = -5.727923; p = 0.008) was significant, whereas the direct effect (b = - 0.03195473, p = 0.903) was not significant (Suppl 2, Table 1). Problem-solving skill (b=-2.84, p = 0.016) was a significant mediator of intervention effects on suicidal ideation (Path a*b).

CONCLUSIONS

This is the first clustered RCT evaluation of the effectiveness of a blended indicated intervention to prevent suicidality in school settings in Latin America. This is the first step to informing policymakers to scale up an effective intervention for an important public health problem.

Prevalence and predictors of suicide ideation among university and high-school students during India's 2nd wave of the COVID-19 pandemic

Student suicide ideation increased globally during the SARS-CoV-2 pandemic. There is scarce literature addressing suicide ideation during global health crises. Therefore, this study investigates prevalence and predictors of suicide ideation during India's COVID-19 Second Wave. We also examine the 3-Step Theory's assertion that both pain and hopelessness are necessary to have suicidal thoughts. Sample recruitment was through an online anonymous questionnaire. Inclusion criteria included students aged 18 or older, living in India during the time of the study (N = 535). Data collection was through the online questionnaire. Three categories of variables were investigated as potential predictors of suicide ideation: Sociodemographic (e.g., age, gender, education, economic status), COVID-19-specific (e.g., online classes, fear of virus contagion, vaccination status) and Clinical (e.g., sad mood, fear, loneliness, hopelessness). Data analysis (using SPSS-26) included descriptive statistics for describing data characteristics, Spearman Rho Correlation (assess the strength and direction of association between variables), and Binary Logistic Regression to help identify predictors of suicide ideation. Ordinal variables were measured using Likert scales with some recoded into binomial variables for the Regression analysis. Clinical variables predicted suicidal ideation, including fear of failure (OR = 4.17, 95% CI:2.51-6.94; p < .001), sleep disturbance (OR = 3.04, CI:1.67-5.52; p < .001), loneliness (OR = 2.77, CI:1.21-6.32; p < .01), sadness (O = 2.89, CI:1.59-5.32), and loss of interest (OR = 2.60, CI:1.37-4.93). Suicidal thoughts were reported by 48.7% of the student-participants. The Three-Step Theory was partially supported, as students feeling psychological pain but not hopelessness still reported suicidal ideation. Anticipating future global health crises, policy-supported mental health mitigation strategies are critically needed for youth, designed to reduce suicidal ideation, enhance resiliency, and to foster mental skills. These should enable them to successfully manage unexpected life challenges.

The effect of once-daily vs. twice-daily intermittent theta burst stimulation on suicidal ideation in treatment-resistant depression

Intermittent theta burst stimulation (iTBS) has demonstrated potential in reducing suicidal ideation (SI) in patients with depression, however, stimulation protocols vary greatly across studies. For this secondary analysis, data from a three-site double-blind, randomized and sham-controlled clinical trial was analyzed to investigate the efficacy of a once-daily versus twice-daily iTBS protocol in the treatment of SI in patients with treatment resistant depression. Secondarily we aimed to explore the associations among SI, anhedonia and quality of life (QOL) measures. The primary outcome for this analysis was SI, which was assessed by computing an average score from four suicidality items on separate depression scales. 158 participants who experienced some degree of SI at baseline were included in the analysis. After 10 days of treatment, 15 (18.3%) participants from the once-daily group and 19 (25%) from the twice-daily group achieved remission from SI which was defined as a SI score of 0. After 30 days of treatment the remission rates were 27 (32.9%) and 30 (39.5%), respectively. There were no significant differences in remission rates between the groups. Moderate correlations between change in SI and change in depressive symptoms were observed. In addition, correlations between change in SI, anhedonia and QOL were observed that remained significant after controlling for change in depressive symptoms. Achieving remission from SI appears to be at least partially correlated to the anti-depressant effect of iTBS. Further studies investigating optimal treatment protocols for the treatment of suicidality with different iTBS schedules are urgently needed.

Correlations between problematic internet use and suicidal behavior among Chinese adolescents: a systematic review and meta-analysis

Background

Problematic Internet Use (PIU) has been increasingly linked to suicidal behavior among adolescents, raising significant public health concerns, particularly in Chinese youth. This study aimed to systematically review and meta-analyze the correlation between PIU and suicidal behavior in Chinese adolescents to provide a clearer understanding of this association.

Methods

A comprehensive search was conducted across seven databases up to July 1, 2024. Studies investigating the relationship between PIU and suicidal behavior among Chinese adolescents were included. A random-effects meta-analysis was employed to assess pooled effect sizes, with subgroup analyses conducted to explore potential moderators, such as geographic region, age, gender, assessment tools for PIU and suicidal ideation, and the presence of depression. Data analysis was performed using STATA software (version 16).

Results

This meta-analysis, comprising 23 studies with 353,904 participants, identified significant associations between PIU and suicidal behavior among Chinese adolescents. PIU was associated with increased risks of suicidal ideation (OR = 1.72, 95% CI: 1.45, 2.03), suicidal plans (OR = 1.50, 95% CI: 1.02, 2.20), and suicidal attempts (OR = 1.48, 95% CI: 1.16, 1.89). Subgroup analyses indicated higher risks in specific groups: adolescents from Central China (OR = 1.84, 95% CI: 1.46, 2.32), college students (OR = 2.09, 95% CI: 1.66, 2.62). The risk of suicidal ideation was particularly elevated when depression was not controlled (OR = 1.86, 95% CI: 1.53, 2.25). These findings underscore the need for targeted interventions in vulnerable populations.

Conclusion

This meta-analysis demonstrated significant associations between PIU and suicidal behaviors among Chinese adolescents. The findings emphasize the need for targeted interventions, particularly for adolescents from Central and Western China, college students, and those with untreated depression. Focused strategies are required to mitigate the risks associated with PIU and to effectively address suicidal behaviors in these high-risk populations.

Suicide risk among adult subjects hospitalized in an acute psychiatric ward: 6-year retrospective investigation

BACKGROUND

The phenomenon of suicide risk (SR) represents a psychiatric, social and environmental emergency. The acute psychiatric ward as the Italian Service for Psychiatric Diagnosis and Care (SPDC) represents the place where SR is high due to the acute and serious conditions of people hospitalized. The objective of this study was to evaluate the characteristics of subjects admitted to a SPDC over a 6-year period for SR represented by: suicidal ideation, attempted and failed suicide.

METHODS

With a retrospective single-center observational design, we collected hospitalizations from 01/01/2017 to 31/12/2022 in the SPDC of AUSL-Modena for SR, analyzed the modality of SR and compared the demographic and clinical variables of subjects with SR with those hospitalized for other clinical reasons in the same period. Data were statistically analyzed.

RESULTS

In the 6-year of study period, we collected 2,930 hospitalizations in the SPDC of AUSL- Modena and among them, 68% (n = 528) were carried out due to SR, which represented the second leading cause of hospitalization (18%), in particular among females (Pearson Chi2 = 17.41, p < 0.001). Individuals with SR were more frequently voluntary admitted (Pearson Chi2 = 215.41, p < 0.001) for a shorter period (7.36 ± 8.16 vs 11.66 ± 15.93, t = 6.03, t-test, p < 0.001) and less frequently repeated the hospitalization during the study period for the same reason (Pearson Chi2 = 6.0, p = 0.014). The most frequent psychiatric disorders associated with SR were depressive, personality and adjustment disorders, which represented the most common factor associated with SR (68%), followed by family/relationship problems (12%) and alcohol/substance abuse (8%). We highlighted three kinds of suicidal risk: suicidal ideation (40%), often associated with personality disorders and substance use disorders, drug ingestion (30%) concomitant with conflicting family relationships and use of violent means (30%) associated with depressive disorders (Pearson Chi2 = 42.83, p = 0.002).

CONCLUSIONS

Our study provides a real-world setting evaluation of subjects hospitalized for SR and, in accordance with literature, suggests that suicidal behavior is the product of many clinical and social factors' interaction, that occurred in a crucial moment of life in vulnerable individuals. The identification of subjects at SR represents the first step of preventive multi-professional interventions.

Comparing suicide risk screening strategies in Spanish-speaking pediatric patients

BACKGROUND

Suicide and suicidal behaviors pose significant global public health challenges, especially among young individuals. Effective screening strategies are crucial for addressing this crisis, with depression screening and suicide-specific tools being common approaches. This study compares their effectiveness by evaluating the Ask Suicide-Screening Questions (ASQ) against item 9 of the Patient Health Questionnaire-A (PHQ-A).

METHODS

This study is a secondary analysis of the Argentinean-Spanish version of the ASQ validation study, an observational, cross-sectional, and multicenter study conducted in medical settings in Buenos Aires, Argentina. A convenience sample of pediatric outpatients/inpatients aged 10 to 18 years completed the ASQ, PHQ-A, and Suicide Ideation Questionnaire (SIQ) along with clinical and sociodemographic questions.

RESULTS

A sample of 267 children and adolescents were included in this secondary analysis. Results show that the ASQ exhibited higher sensitivity (95.1%; 95% CI: 83% - 99%) compared to PHQ-A item 9 (73.1%; 95% CI: 57% - 85%), and superior performance in identifying suicide risk in youth.

LIMITATIONS

The study included a convenience sampling and was geographically restricted to Buenos Aires, Argentina. The study also lacked longitudinal follow-up to assess the predictive validity of these screening tools for suicide risk.

CONCLUSION

The study highlights the ASQ's effectiveness in identifying suicide risk among youth, emphasizing the importance of specialized screening tools over depression screening tools alone for accurate risk assessment in this population.

Gender-specific factors of suicidal ideation among high school students in Yunnan province, China: A machine learning approach

BACKGROUND

Suicidal ideation (SI) assumes a pivotal role in predicting suicidal behaviors. The incidence of SI among high (junior and senior) school students is significantly higher than that of other age groups. The aim of this study is to explore the gender differences in SI among high school students in Yunnan Province.

METHOD

A total of 6180 students in grades 7-12 in Yunnan province, China from May 2021 to May 2022 participated in this survey. Univariate analysis was employed to describe the influencing factors of male and female students' SI. Subsequently, data were stratified by gender. Adopting machine learning technique, including Least Absolute Shrinkage and Selection Operator (Lasso) and Boruta algorithm, and logistic regression model to estimate the direction and effect magnitude of the influencing factors.

RESULTS

The prevalence of SI was significantly higher for females (31.34 %) than males (16.73 %). The logistic regression model was established using the variables screened by Boruta algorithm, indicated that anxiety, depression, suffering emotion abuse or emotion neglect in childhood, non-suicidal self-injury, evening chronotype are common risk factors for SI in male and female students. Notably, female students who exhibited aggressive behavior, have experienced bullying, and were in the junior high school learning stage were more likely to report SI than their male counterparts.

CONCLUSIONS

Females showed more vulnerability to SI than males especially among females in junior high school, reporting aggressive behavior and bullying experiences. Tailored prevention strategies, informed by these gender-related distinctions, should be developed and implemented.

The relationship between nocturia and suicidal ideation: A study on The National Health and Nutrition Survey data

OBJECTIVES

The focus of this research was to explore any potential link between nocturia and the risk of suicidal ideation.

METHODS

Drawing from the National Health and Nutrition Survey, data relating to 25 241 participants was scrutinized. This included 13 421 individuals identifying as male and 11 820 individuals identifying as female. Participants provided information on nocturia and suicidal ideation via self-completed questionnaires. To determine if nocturia was independently related to suicidal ideation, a multivariable logistic regression analysis was employed. Analyses were also undertaken separately for adult males and females.

RESULTS

It was found that around 3.5% of participants had experienced suicidal ideation. The results indicated that nocturia increased the risk for suicidal ideation in all adult groups (odds ratio [OR] = 1.67, 95% confidence interval[CI]: 1.37-2.03, p < 0.0001), including both males (OR = 1.91, 95% CI: 1.38-2.65, p < 0.001) and females (OR = 1.48, 95% CI: 1.158-1.90, p = 0.002). The risk for suicidal ideation increased with the severity of nocturia, with significant trends observed in adult males (p for trend = 0.04) and adult females (p for trend = 0.01). Additionally, subgroup examination showed a significant interaction between nocturia and educational level in adult males (p for interaction = 0.03). Among adult females, a noteworthy interaction was observed between nocturia and body mass index (p for interaction = 0.02).

CONCLUSION

The research uncovered a connection between nocturia and an elevated risk of suicidal ideation.

Profiles of Suicidal Ideation Among Black Male Adolescents: Examination of Individual and Socioecological Predictors

OBJECTIVE

The current study utilized latent profile analysis to identify distinct profiles of suicidal ideation among Black male adolescents and compared profiles on socioecological determinants of suicide and psychological symptoms.

METHOD

A sample of 457 Black male adolescents (mean age = 15.31, SD = 1.26) completed self-report measures of suicidal ideation, racial discrimination, community violence exposure, anxiety symptoms, depressive symptoms, and posttraumatic stress symptoms.

RESULTS

Results of the latent profile analysis revealed a three-profile model: a low ideation profile, with low levels of all forms of suicidal ideation; a general death ideation profile with elevated general thoughts of death and dying; and a high, concealed ideation profile with high levels on all suicidal ideation items, except communicating the ideation to others. ANOVAs revealed that levels of psychological symptoms were significantly different for each profile, with the high, concealed ideation profile showing the highest levels. The low ideation profile had significantly lower scores than the two other profiles on community violence exposure, but the other two profiles did not differ significantly from one another. Further, the general death ideation profile had significantly higher scores on racial discrimination than the other two profiles, but the other two profiles did not differ significantly from one another.

CONCLUSIONS

The current study supports recent socio-cultural theories of suicidal ideation and behavior in Black youth and highlights the need for increased access to care and services for Black boys who are exposed to socioecological factors that heighten suicidal ideation.

Therapeutic alliance and suicidal ideation in brief cognitive behavioral therapy for outpatients

OBJECTIVE

The therapeutic alliance is central to psychotherapy. However, research on the relationship between alliance and suicidality is scarce. We examined whether pretreatment suicidality is associated with an impaired alliance formation in brief cognitive behavioral therapy (CBT) and whether the therapeutic alliance is associated with change in suicidal ideation (difference between pretreatment and posttreatment assessment).

METHODS

N = 643 outpatients (64% female; age: M[SD] = 37.09[13.15], range: 18-73 years), received 12 sessions of manual-based short-term CBT for primary diagnosis treatment. Using self-report questionnaires, suicidal ideation and behavior were assessed before and after therapy, patient-rated therapeutic alliance was assessed after the fourth session and posttreatment. We performed correlation analyses and two hierarchical linear regressions, unadjusted and adjusted for possible confounding variables (age, gender, lifetime suicide attempts and depression).

RESULTS

Pretreatment suicidal ideation was not predictive of the quality of the early alliance. In addition, the therapeutic alliance was not predictive of change in suicidal ideation.

CONCLUSIONS

In the outpatient setting, no association was found between therapeutic alliance and suicidality. Future studies should investigate therapeutic alliance as a predictor of prospective suicidal behavior in different clinical settings.

Cross-sectional study about suicide ideation and attempts among Brazilian pre-adolescents

BACKGROUND

Suicide is a global public health problem. In childhood, the risk factors are less clear, highlighting family and individual factors. This study aims to investigate the prevalence and sociodemographic, social, family, and individual factors associated with suicide ideation and attempts in pre-adolescents in a Brazilian city.

METHODS

The sample comes from a cohort of 500 schoolchildren of a city in Rio de Janeiro/Brazil. The data are analyzed cross-sectionally. The research incorporated data from the years 2005, 2006, and 2008 to evaluate suicide ideation and attempts in childhood, as reported by parents/caregivers, teachers and children. A hierarchical logistic model evaluated the association between the explanatory variables related to sociodemographic, social, family, and individual factors and the outcome.

RESULTS

22.2% of the children (95% CI 18.0%-27.0%) had suicide ideation/attempts, reported either by their mothers, teachers, or the child at some point in a cohort. The following variables were associated with suicidal ideation/attempts in the final adjusted model: regular or poor quality of relationship with friends (OR = 1.84; 95% CI 1.31-2.58), having a family member incarcerated (OR = 1.44; 95% CI 1.07-1.92) and having worse performance in portuguese or mathematics than other students (OR = 2.05; 95% CI 1.29-3.26).

CONCLUSION

Suicidal behavior in childhood is severe and affects everyone around the case, demanding to promote friendships, helping with school activities, and providing greater support and attention to children at risk. Bad relationships with friends and incarcerated family members are particularly key risk factors for suicide ideation and attempts. It is essential to improve prevention policies and to disseminate protective behaviors. There is a critical need to augment community mental health resources, mainly in less developed countries and regions that lack these services.

Clinical characteristics and suicidal ideation as predictors of suicide: prospective study of 1000 referrals to general adult psychiatry

AIMS AND METHOD

Questions often follow the suicide of someone who presented to general adult psychiatry (GAP) when expressing suicidal thoughts: 'Why were they not admitted, or managed differently, when they said they were suicidal?' Answering these questions requires knowledge of the prevalence of suicidal ideation in patients presenting to GAP. Therefore, we determined the general clinical characteristics, including suicidal ideation, of a large sample of patients presenting to a GAP emergency assessment service or referred as non-emergencies to a GAP service.

RESULTS

Suicidal ideation was very common, being present in 76.4% of emergency presentations and 33.4% of non-emergency referrals. It was very weakly associated with suicide, varied between different diagnostic categories, and previous assessment by GAP did not appear to affect it. The suicide rate during the contingent episode of care was estimated as 66 per 100 000 episodes.

CLINICAL IMPLICATIONS

This, and other evidence, shows that suicide cannot be predicted with an accuracy that is useful for clinical decision-making. This is not widely appreciated but has serious consequences for patients and healthcare resources.

Perinatal Factors and Their Association with Early-Adulthood Suicidal Behavior in a Brazilian Birth Cohort

BACKGROUND

The objectives of this study were to investigate the relationship between perinatal risk factors and suicidal ideation and attempts in young adults in Pelotas, Brazil.

METHODS

The data were collected from the 1993 Pelotas Birth Cohort study. Every pregnant woman who gave birth in one of the hospitals in Pelotas Brazil in 1993 was invited to participate in the study. The current study uses perinatal data collected in 1993, and follow-ups at ages 18 and 22. The primary outcome was lifetime suicide attempts with past month suicide ideation a secondary outcome. The association between perinatal predictors and suicidal ideation or lifetime suicide attempts was investigated using hierarchical logistic regression.

FINDINGS

There was an analytic sample size of 3493. The perinatal factors association with lifetime suicide attempts were sex (OR = 2.25 CI: 1.76-2.89), paternal education at birth (OR = 0.60, 95%CI: 0.36-0.99), maternal education (9-11 years OR = 2.81, 95%CI: 1.41-5.59, & 0-8 years OR = 2.21, 95%CI: 1.07-4.58), support from friends or neighbors at birth (OR = 0.36 95%CI: 0.17-0.77), and maternal smoking during pregnancy (OR = 1.41, 95%CI: 1.10-1.79). Patterns of associations were broadly similar with suicidal ideation. Interactions between sex and the perinatal factors paternal education, maternal education, smoking and support from friends were assessed and found to be not significant.

CONCLUSION

Several factors during the perinatal period are associated with risk of lifetime suicide attempts and ideation in young adults in Brazil. Early-life factors associated with suicide-related concerns in early adulthood were similar to those observed in studies from high-income settings.

Transitions in Suicide Risk from Early Adolescence to Early Adulthood

OBJECTIVE

Understanding patterns of suicide risk over the course of development can aid our ability to prevent suicide. Our community-based study examined changes in suicide risk status and predictors of changes in risk status in a sample of 521 adolescents over six assessments between the start of middle school and young adulthood (ages 12-22).

METHODS

Suicidal thoughts and behaviors (STB) were measured with the Diagnostic Interview Schedule for Children and the Moods and Feelings Questionnaire. Latent transition analysis (LTA) was utilized to evaluate transitions in suicide risk status over the course of development. Nine risk factors' initial values and change over time were modeled as predictors in the LTA.

RESULTS

Latent class analysis identified a four-class model of developmental suicide risk patterns: Class 1: Infrequent STB (73-87% of participants), Class 2: Diminishing STB (1-17% of participants), Class 3: Escalating STB (6-16% of participants), and Class 4: Consistently High STB (1-5% of participants). LTA demonstrated that infrequent STB members and escalating STB members were likely to maintain their risk class across time points.

CONCLUSIONS

Classification of STB trajectories demonstrated self-worth and family involvement were salient variables affecting transitions in risk over time and suggest prevention targets early in adolescence that could have impact on suicide risk in adulthood.

Reappraisal Mitigates, While COVID-19 Burnout Exacerbates the Impact of Depressive Symptoms on Suicidal Ideation Among Chinese College Students

Background

Suicide is a global public health issue. This study examined the role of COVID-19 burnout and reappraisal in suicidal ideation caused by depressive symptoms among Chinese college students.

Methods

587 students (261 boys, M age = 19.53, SD = 1.42) were assessed using the Short Depression-Happiness Scale (SDHS), Positive and Negative Suicide Ideation (PANSI) inventory, and Emotion Regulation Scale (ERS).

Results

Correlation analysis indicated depressive symptoms were negatively correlated with reappraisal and positively correlated with suicidal ideation and COVID-19 burnout. Reappraisal was negatively correlated with suicidal ideation and COVID-19 burnout. The moderated mediation model showed COVID-19 burnout enhanced the direct effect of depressive symptoms on suicidal ideation and indirectly enhanced this effect by weakening the protective role of reappraisal.

Conclusion

These finding show that reappraisal acts as a protective factor against suicidal ideation in individuals with depressive symptoms, while COVID-19 burnout exacerbates this effect by weakening reappraisal's protective role.

Protective factors for suicidal ideation: a prospective study from adolescence to adulthood

Adolescent suicidality is associated with negative outcomes in adulthood. Suicide prevention has traditionally focused on identifying risk factors, yet suicide rates have remained stable. With suicidality often going undetected-especially suicidal ideation, further knowledge about protective factors is needed. The main objective of this study was to investigate potential protective factors for suicidal ideation from adolescence to adulthood. The study employed longitudinal population survey data, "Youth and Mental Health Study" consisting of self-reports at two-time points (mean age 14.9, SD = 0.6 and 27.2, SD = 0.6) (n = 2423 and n = 1198). Protective factors (at individual, social and environmental level) were selected based on a priori knowledge. Internal consistency of scales was analyzed using McDonald's omega. We used a linear mixed model with suicidal ideation as the dependent variable, time-points, a protective factor variable and their interaction as covariates, and individual participant as random effects. We adjusted for sex and also conducted separate analyses for males and females. The Benjamini-Hochberg procedure was used to adjust p-values for multiple hypotheses. Investigated protective factors were associated with temporal change in suicidal ideation (significant interactions). For both sexes, less emotion-orientated coping, higher self-perception scores, greater levels of physical activity and higher school wellbeing/connectedness were protective factors for suicidal ideations. Secure attachment and higher family function were protective factors for females only. The effects in adolescence were mostly maintained in adulthood. In this study, several protective factors for suicidal ideation persisted into adulthood, with distinct differences between males and females.

Frequency of suicidal ideation inventory: A reliability generalization meta-analysis

The objectives of this reliability generalization meta-analysis were to estimate the overall reliability of the Frequency of Suicidal Ideation Inventory (FSII), a short, easily administered test developed to assess suicidal ideation and to examine possible moderating variables. A systematic search was conducted in five databases from the year of publication (2016) of the FSII until March 2024. All studies that applied the FSII and reported a Cronbach's alpha coefficient were included. Analyses were performed using a random effects model applying Bonett's transformation. Our analysis of 32 studies (k = 39) yielded an overall alpha of .91 (95% CI = .90, .92). We found that the type of administration, population, and language of the FSII moderated its reliability, which is high overall and appropriate for use in both research and clinical settings.

Study protocol for an adaptive, multi-arm, multi-stage (MAMS) randomised controlled trial of brief remotely delivered psychosocial interventions for people with serious mental health problems who have experienced a recent suicidal crisis: Remote Approaches to Psychosocial Intervention Delivery (RAPID)

BACKGROUND

People with serious mental health problems (SMHP) are more likely to be admitted to psychiatric hospital following contact with crisis services. Admissions can have significant personal costs, be traumatic and are the most expensive form of mental health care. There is an urgent need for treatments to reduce suicidal thoughts and behaviours and reduce avoidable psychiatric admissions.

METHODS

A multi-stage, multi-arm (MAMS) randomised controlled trial (RCT) with four arms conducted over two stages to determine the clinical and cost effectiveness of three psychosocial treatments, compared to treatment as usual (TAU), for people with SMHP who have had recent suicidal crisis. Primary outcome is any psychiatric hospital admissions over a 6-month period. We will assess the impact on suicidal thoughts and behaviour, hope, recovery, anxiety and depression. The remote treatments delivered over 3 months are structured peer support (PREVAIL); a safety planning approach (SAFETEL) delivered by assistant psychologists; and a CBT-based suicide prevention app accessed via a smartphone (BrighterSide). Recruitment is at five UK sites. Stage 1 includes an internal pilot with a priori progression criteria. In stage 1, the randomisation ratio was 1:1:1:2 in favour of TAU. This has been amended to 2:2:3 in favour of TAU following an unplanned change to remove the BrighterSide arm following the release of efficacy data from an independent RCT. Randomisation is via an independent remote web-based randomisation system using randomly permuted blocks, stratified by site. An interim analysis will be performed using data from the first 385 participants from PREVAIL, SAFETEL and TAU with outcome data at 6 months. If one arm is dropped for lack of benefit in stage 2, the allocation ratio of future participants will be 1:1. The expected total sample size is 1064 participants (1118 inclusive of BrighterSide participants).

DISCUSSION

There is a need for evidence-based interventions to reduce psychiatric admissions, via reduction of suicidality. Our focus on remote delivery of established brief psychosocial interventions, utilisation of different modalities of delivery that can provide sustainable and scalable solutions, which are also suitable for a pandemic or national crisis context, will significantly advance treatment options.

Changes in suicidal ideation during treatment among patients with major depressive disorder: A 6-month naturalistic follow-up study

AIM

There is limited evidence regarding predictors of changes in suicidal ideation (SI) in patients with major depressive disorder (MDD). The objective of this study was to describe changes in SI over a 6-month period and identify their predictors from naturalistic observations of MDD patients.

METHODS

In the cross-sectional analysis, we examined 257 patients with MDD at the first-visit assessment. Among the patients, 119 who completed the 6-month assessment (completers) were included in the longitudinal analysis. For the evaluation of depressive symptoms, including SI, the Quick Inventory of Depressive Symptomatology-Japanese version was administered at both the first-visit and follow-up assessments. At baseline, we also administered the Japanese version of the Ten Item Personality Inventory to assess personality traits and the PRIME Screen-Revised to assess psychotic symptoms.

RESULTS

In the cross-sectional analysis of first-visit patients, 36.2% (93/257) exhibited SI. Among completers, 14.3% (17/119) had prolonged SI. Among the completers with SI at the first-visit assessment, 38.6% (17/44) had SI at the follow-up assessment (prolonged SI). In linear regression models including all completers, prolonged SI was positively associated with endorsement of suspiciousness/persecutory ideas and negatively associated with higher age.

CONCLUSION

More than one-third of completers who had SI at the first-visit assessment experienced prolonged SI (SI at follow-up). Our findings can help clinicians predict the course of MDD by identifying associated demographic and clinical characteristics.

Ethological Problems with the Interpersonal Theory of Suicide

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

Exploring community mental health service use following hospital-treated intentional self-harm among older Australians: a survival analysis

OBJECTIVES

This study aimed to examine the impact of community mental health (CMH) care following index hospital-treated intentional self-harm (ISH) on all-cause mortality. A secondary aim was to describe patterns of CMH care surrounding index hospital-treated ISH.

DESIGN

A longitudinal whole-of-population record linkage study was conducted (2014-2019), with index ISH hospitalization (Emergency Department and/or hospital admissions) linked to all available hospital, deaths/cause of death, and CMH data.

SETTING

Australia's most populous state, New South Wales (NSW) comprised approximately 7.7 million people during the study period. CMH services are provided statewide, to assess and treat non-admitted patients, including post-discharge review.

PARTICIPANTS

Individuals with an index hospital presentation in NSW of ISH during the study period, aged 45 years or older.

INTERVENTION

CMH care within 14 days from index, versus not.

MEASUREMENTS

Cox-proportionate hazards regression analysis evaluated all-cause mortality risk, adjusted for relevant covariates.

RESULTS

Totally, 24,544 persons aged 45 years or older experienced a nonfatal hospital-treated ISH diagnosis between 2014 and 2019. CMH care was received by 56% within 14 days from index. Survival analysis demonstrated this was associated with 34% lower risk of death, adjusted for age, sex, marital status, index diagnosis, and 14-day hospital readmission (HR 0.66, 95% CI 0.58, 0.74, p < 0.001). Older males and chronic injury conveyed significantly greater risk of death overall.

CONCLUSIONS

CMH care within 14 days of index presentation for self-harm may reduce the risk of all-cause mortality. Greater effort is needed to engage older males presenting for self-harm in ongoing community mental health care.

Effect of next-step antidepressant treatment on suicidal ideation: findings from the VAST-D trial

BACKGROUND

Major depressive disorder (MDD) contributes to suicide risk. Treating MDD effectively is considered a key suicide prevention intervention. Yet many patients with MDD do not respond to their initial medication and require a 'next-step'. The relationship between next-step treatments and suicidal thoughts and behaviors is uncharted.

METHOD

The VA Augmentation and Switching Treatments for Depression trial randomized 1522 participants to one of three next-step treatments: Switching to Bupropion, combining with Bupropion, and augmenting with Aripiprazole. In this secondary analysis, features associated with lifetime suicidal ideation (SI) and attempts (SA) at baseline and current SI during treatment were explored.

RESULTS

Compared to those with SI only, those with lifetime SI + SA were more likely to be female, divorced, or separated, unemployed; and to have experienced more childhood adversity. They had a more severe depressive episode and were more likely to respond to 'next-step' treatment. The prevalence of SI decreased from 46.5% (694/1492) at baseline to 21.1% (315/1492) at end-of-treatment. SI during treatment was associated with baseline SI; low positive mental health, more anxiety, greater severity and longer duration of current MDD episode; being male and White; and treatment with S-BUP or C-BUP as compared to A-ARI.

CONCLUSION

SI declines for most patients during next-step medication treatments. But about 1 in 5 experienced emergent or worsening SI during treatment, so vigilance for suicide risk through the entire 12-week acute treatment period is necessary. Treatment selection may affect the risk of SI.

Neurological, Metabolic, and Psychopathological Correlates of Lifetime Suicidal Behaviour in Major Depressive Disorder without Current Suicide Ideation

INTRODUCTION

Suicidal behaviour (SB) has a complex aetiology. Although suicidal ideation (SI) is considered the most important risk factor for future attempts, many people who engage in SB do not report it.

METHODS

We investigated neurological, metabolic, and psychopathological correlates of lifetime SB in two independent groups of patients with major depression (sample 1: n = 230; age: 18-65 years; sample 2: n = 258; age >60 years) who did not report SI during an index episode.

RESULTS

Among adults (sample 1), SB was reported by 141 subjects (58.7%) and severe SB by 33 (15%). After controlling for interactions, four risk factors for SB emerged: male gender (OR 2.55; 95% CI: 1.06-6.12), negative self-perception (OR 1.76; 95% CI: 1.08-2.87), subthreshold hypomania (OR 4.50; 95% CI: 1.57-12.85), and sexual abuse (OR 3.09; 95% CI: 1.28-7.48). The presence of at least two of these factors had the best accuracy in predicting SB: sensitivity = 57.6% (39.2-74.5); specificity = 75.1% (68.5-82.0); PPV = 27.9% (20.9-37.2); NPV = 91.4% (87.6-94.1). In older patients (sample 2), 23 subjects (9%) reported previous suicide attempts, which were characterized by earlier onset (25 years: OR 0.95: 0.92-0.98), impaired verbal performance (verbal fluency: OR 0.95: 0.89-0.99), higher HDL cholesterol levels (OR 1.04: 1.00-1.07) and more dyskinesias (OR 2.86: 1.22-6.70).

CONCLUSION

Our findings suggest that SB is common in major depressive disorder, even when SI is not reported. In these individuals it is feasible and recommended to investigate both psychiatric and organic risk factors. The predictive power of models excluding SI is comparable to that of models including SI.

Suicidal ideation in Chinese patients with advanced breast cancer: a multi-center mediation model study

PURPOSE

The pathways underpinning suicide ideation (SI) and certain physical and psychological factors in patients with advanced breast cancer remain unclear. This study develops and validates a mediation model that delineates the associations between several multidimensional variables and SI in Chinese patients with advanced breast cancer.

METHODS

Patients with advanced breast cancer (n = 509) were recruited as study participants from 10 regional cancer centers across China from August 2019 to December 2020. Participants were required to complete five questionnaires using an electronic patient-reported outcomes (ePRO) system: 9 item- Patient Health Questionnaire (PHQ-9), Hospital Anxiety and Depression Scale (HADS), Insomnia Severity Index (ISI), 5-level EQ-5D (EQ-5D-5L), and MD Anderson Symptom Inventory (MDASI). Risk factors for SI were identified using multivariable logistic regression, and inputted into serial multiple mediation models to elucidate the pathways linking the risk factors to SI.

RESULTS

SI prevalence was 22.8% (116/509). After adjusting for covariates, depression (odds ratio [OR] = 1.384), emotional distress (OR = 1.107), upset (OR = 0.842), and forgetfulness (OR = 1.236) were identified as significant independent risk factors (all p < 0.05). The ORs indicate that depression and distress have the strongest associations with SI. Health status has a significant indirect effect (OR=-0.044, p = 0.005) and a strong total effect (OR=-0.485, p < 0.001) on SI, mediated by insomnia severity and emotional distress.

CONCLUSIONS

There is a high SI prevalence among Chinese patients with advanced breast cancer. Our analysis revealed predictive pathways from poor health to heightened SI, mediated by emotional distress and insomnia. Regular management of distress and insomnia can decrease suicide risk in this vulnerable population.

Suicide ideation and male-female differences in major depressive disorder

OBJECTIVE

This study aimed to explore male-female differences in suicide ideation (SI) and suicide risk factors in major depressive disorder (MDD).

METHODS

We analysed 482 adults (sample 1) and 438 elderly outpatients (sample 2) with MDD. Sample 1 was treated with different antidepressant combinations (escitalopram; bupropion plus escitalopram; venlafaxine plus mirtazapine) and assessed by means of the Concise Health Risk Tracking (SI), Quick Inventory of Depressive Symptomatology, Altman Mania Rating Scale and Psychiatric Diagnostic Screening Questionnaire. Sample 2 was treated with venlafaxine and assessed using the Hamilton scale for depression, Anxiety Sensitivity Index and Penn State Worry Questionnaire for anxiety, Beck Scale for Suicide Ideation and Repeatable Battery for the Assessment of Neuropsychological Status.

RESULTS

In sample 1, females had greater depression severity (O.R 0.961 99%CI: 0.929 - 0.995), males reported more alcohol abuse (O.R 1.299 99%CI: 1.118 - 1.509) and active SI (O.R 1.109 99%CI: 1.005 - 1.255). In sample 2 men showed more severe SI (O.R 1.067; 99%CI: 1.014 - 1.122) and weight loss (OR = 5.89 99%CI: 1.01 - 34.19), women more gastrointestinal symptoms.

CONCLUSIONS

In these selected samples, although women had more severe depression, men had more suicide risk factors. Such differences might contribute to men's increased suicide risk.

Self-harm and suicidal ideation among young people is more often recorded by child protection than health services in an Australian population cohort

OBJECTIVE

We investigated patterns of service contact for self-harm and suicidal ideation recorded by a range of human service agencies - including health, police and child protection - with specific focus on overlap and sequences of contacts, age of first contact and demographic and intergenerational characteristics associated with different service responses to self-harm.

METHODS

Participants were 91,597 adolescents for whom multi-agency linked data were available in a longitudinal study of a population cohort in New South Wales, Australia. Self-harm and suicide-related incidents from birth to 18 years of age were derived from emergency department, inpatient hospital admission, mental health ambulatory, child protection and police administrative records. Descriptive statistics and binomial logistic regression were used to examine patterns of service contacts.

RESULTS

Child protection services recorded the largest proportion of youth with reported self-harm and suicidal ideation, in which the age of first contact for self-harm was younger relative to other incidents of self-harm recorded by other agencies. Nearly 40% of youth with a health service contact for self-harm also had contact with child protection and/or police services for self-harm. Girls were more likely to access health services for self-harm than boys, but not child protection or police services.

CONCLUSION

Suicide prevention is not solely the responsibility of health services; police and child protection services also respond to a significant proportion of self-harm and suicide-related incidents. High rates of overlap among different services responding to self-harm suggest the need for cross-agency strategies to prevent suicide in young people.

Personality Pathology and Suicide Risk: Examining the Relationship Between DSM-5 Alternative Model Traits and Suicidal Ideation and Behavior in College-Aged Individuals

BACKGROUND

This study examines the link between personality pathology and suicide risk regarding the DSM-5 alternative model of personality disorders.

METHOD

The study investigates the facets, domains, internalizing, and externalizing of personality pathology and their correlation and predictive significance for suicidal ideation and behavior. This study examined a diverse and balanced sample of 1,398 college students aged between 18- and 29-year-olds from nine colleges in Kafrelshiekh University, with nearly equal representation of both genders (687 males, 711 females), a mix of rural and urban residents (807 rural, 591 urban), and a wide range of socioeconomic backgrounds (15 very low SES, 84 low SES, 878 moderate SES, 364 high SES, and 57 very high SES). The Personality Inventory for the DSM-5 (PID-5) was utilized to assess personality pathology. Columbia-Suicide Severity Rating Scale (C-SSRS) was used to evaluate suicidal ideation and behavior.

RESULTS AND DISCUSSION

Logistic regression reveals significant associations between personality traits and suicidal ideation (e.g., Anhedonia, Suspiciousness) and behavior (e.g., Risk Taking, Depressivity). Negative Affect and Detachment are significantly linked to suicidal ideation, while Detachment, Disinhibition, and Psychoticism are linked to suicidal behavior. Internalizing personality pathology predicts both ideation and behavior, indicating a contribution to suicidal thoughts and self-destructive acts. Externalizing is a significant predictor of suicidal behavior.

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

INTRODUCTION

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

METHODS

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

RESULTS

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

CONCLUSIONS

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

Non-suicidal self-injury and suicidal ideation among adolescents: the chain-mediating role of rumination and decentering

Objective

To explore the relationship between non-suicidal self-injury and suicidal ideation in adolescents and examine the roles of rumination and decentering in that relationship.

Method

By means of a questionnaire, 175 adolescent patients in a psychiatric hospital in Fujian Province were given the Functional Assessment of Self-Mutilation: Chinese Version, Positive and Negative Suicide Ideation, Ruminative Response Scale: Chinese Version, and Experiences Questionnaire: Decentering Scale.

Results

(1) Adolescent non-suicidal self-injury was significantly positively related to suicidal ideation and rumination and significantly negatively related to decentering. Suicidal ideation was significantly positively related to rumination and significantly negatively related to decentering. Rumination was significantly negatively related to decentering. (2) Rumination and decentering played a complete chain-mediating role between non-suicidal self-injury and suicidal ideation. Non-suicidal self-injury was found to indirectly affect suicidal ideation along three pathways: the independent mediating role of rumination (the mediating effect accounted for 40.166%), independent mediating role of decentering (the mediating effect accounted for 41.274%), and chain-mediating role of rumination and decentering (the mediating effect accounted for 14.958%).

Conclusion

Adolescent non-suicidal self-injury can indirectly affect suicidal ideation through rumination and decentering. In the future, mindfulness and other methods should be used to improve individuals' levels of decentering and cultivate emotional regulation abilities, so as to reduce the incidence of non-suicidal self-injury and suicide in adolescents.

Correlations between negative life events and suicidal ideation among Chinese adolescents: a meta-analysis

Background

Suicide ideation (SI) has become a serious social issue worldwide, and research has found a certain correlation between negative life events (NLE) and SI. Nevertheless, this relationship is still not clear among Chinese adolescents, a special population. Hence, this investigation performed a meta-analysis of observational research on the correlation between NLE and SI among adolescents in China, to further clarify the association.

Methods

We performed an extensive search on seven electronic databases starting from their establishment until March 10, 2023. The research mainly focused on cross-sectional studies conducted on samples of Chinese adolescents. To examine the association between NLE and SI, a meta-analysis model using random effects was utilized. To investigate moderating factors such as age, region, assessment tools for SI, and year of publication, subgroup and meta-regression analyses were performed. The AHRQ evaluated the quality of the study. The synthesis of data was conducted utilizing STATA software (version 16).

Results

Ultimately, a total of 30 cross-sectional studies were selected for this analysis, including 39,602 individuals in the participant sample. The results showed that NLE was moderately positively correlated with SI among Chinese adolescents (r = 0.29, 95% CI: 0.26, 0.32). In addition, this relationship was moderated by regional differences and the measurement tool used for SI. Studies conducted in Western China showed a higher correlation coefficient than those conducted in Eastern and Central China. Moreover, research conducted with the SSIOSS demonstrated a stronger correlation coefficient compared to studies utilizing the BSI-CV or other assessment instruments.

Conclusion

This meta-analysis indicates that NLE is linked to SI in Chinese teenagers, especially those residing in Western regions of China. Identifying and intervening in NLE and associated risk factors are crucial to prevent suicide within this demographic.

Does the need for uniqueness lead to non-suicidal self-injury? The mediation of depression and the moderation of gender

Objective

Based on the integrated theoretical model of the development and maintenance of non-suicidal self-injury (NSSI) and gender role theory, this study investigated the longitudinal impact of the need for uniqueness on NSSI among adolescents, and the mediating role of depression and the moderating role of gender.

Participants

A total of 1,166 middle school students (Mean age = 13.04, SDage = 0.78, range = 11-16) from a city in central China was recruited to complete the Need for Uniqueness Scale, Depression Scale, and Adolescent Self-Injury Questionnaire at two waves. The participants included 475 boys and 457 girls.

Methods

Convenience sampling was used, and a longitudinal study (2 time points with a 6-month interval) was conducted to test our hypotheses. SPSS 25.0 was used to evaluate reliability, and to calculate descriptive statistics and Pearson correlation. PROCESS version 3 was used to test longitudinal relationships among the need for uniqueness, depression and NSSI, and construct a moderated mediation model.

Results

Results revealed that T1 need for uniqueness in adolescents was significantly positively associated with T2 NSSI and T2 depression, and T2 depression was significantly positively associated with T2 NSSI. After controlling for gender, T1 need for uniqueness positively predicted T2 NSSI. Furthermore, the mediation analysis demonstrated that the pathway linking T1 need for uniqueness to T2 NSSI through T2 depression was statistically significant. Moreover, gender moderated the indirect effect from T2 depression to T2 NSSI in the association between T1 need for uniqueness and T2 NSSI. Compared to boys in the same situation, girls who are susceptible to depression were more likely to commit NSSI.

Conclusion

This study demonstrated that the need for uniqueness in adolescents longitudinally predicts NSSI through the mediating role of depression and gender moderates the indirect effect from depression to NSSI. The current study not only suggests that the need for uniqueness is a risk factor for NSSI among adolescents, but also provides an empirical basis for the prevention and intervention of NSSI.

The Columbia-suicide severity rating scale: validity and psychometric properties of an online Spanish-language version in a Mexican population sample

The aim of this study was to evaluate the validity and psychometric properties in a Mexican sample of a Spanish-language online version of the Columbia-Suicide Severity Rating Scale (C-SSRS). Data were collected between May and October 2021 from 3,645 participants aged 18 years and over, who agreed to complete the questionnaire. Reliability analysis, confirmatory factor analysis (CFA), and psychometric properties were calculated using a two-parameter model. The results showed a reasonable level of reliability with a Cronbach's alpha of 0.814, and evidence of unidimensionality, and construct validity for suicide risk at three risk levels: low, medium, and high. Analysis of the items suggests that they are consistent with the proposed theoretical model. Our results also demonstrate that the parameters are stable and able to efficiently discriminate individuals at high risk of suicide. We propose the use of this version of the C-SSRS in the Spanish-speaking population, since it is a multifactorial assessment of suicide risk and the inclusion of other clinical and risk factor assessments for a more comprehensive evaluation.

Self-harm risk screening on prison entry: assessing the predictive validity of self-harm history and recent ideation in men and women

PURPOSE

Rates of self-harm are elevated in prison, and there is limited evidence to support the efficacy of brief risk screening at reception to predict and prevent self-harm. This study aims to examine the predictive validity of the self-harm/suicide screening items embedded in a prison mental health screening tool from two key domains strongly associated with risk: previous suicidal/self-harm behaviour, and recent ideation.

DESIGN/METHODOLOGY/APPROACH

A sample of men and women were screened on entry to prison, with eight screening items covering the two key domains of risk. Follow-up data on self-harm incidents were collected for 12 months post-screening. The predictive validity of individual screening items, item combinations and cumulative screening score was examined for the overall sample and for men and women separately.

FINDINGS

Individual screening items across the two domains were all strongly associated with self-harm in the follow-up period, with odds ratios varying from 2.34 to 9.24. The predictive validity of both individual items, item scores and item combinations demonstrated high specificity but low to moderate sensitivity, and modest area under the curves (AUCs). Predictive validity was generally better for men than women; however, differences were not statistically significant.

PRACTICAL IMPLICATIONS

Identifying those at risk of self-harm in prisons remains challenging and brief universal screening at prison entry should be only one component of a broader prison risk assessment and management strategy.

ORIGINALITY/VALUE

To the best of the authors' knowledge, this study is one of very few to prospectively examine self-harm behaviour following risk screening. Predictive validity was examined in a representative sample of individuals in custody, and for men and women separately.

A qualitative study on lived experience of self-harm in South Asians in the UK: From reasons to recovery

OBJECTIVES

Self-harm rates and clinical presentations differ by ethnicity. South Asian women are at risk of self-harm. Previous research suggested investigating individuals' experiences with self-harm with qualitative studies in developing self-harm prevention strategies. This research aims to explore self-harm experiences among South Asians in the United Kingdom.

DESIGN

Qualitative study.

METHODS

Participants were recruited via third-sector organizations and online platforms. Semi-structured interviews were conducted with 11 South Asian individuals with a history of self-harm living in the United Kingdom. The data were analysed based on a reflective thematic analysis approach.

RESULTS

Results revealed four main themes: (1) reasons for self-harm; (2) recovery journey; (3) culture and mental health; and (4) the transition to suicidal thoughts and behaviours. Reasons for self-harm included negative life circumstances, social life difficulties, challenges faced during COVID-19 and mental health problems. Participants described their recovery journey by acknowledging the role of professional help, self-care, psychoeducation and personal growth, improving social relationships, and faith and spirituality. Cultural factors included generational differences and stigma. Culturally adapted psychological interventions were perceived as promising. The reported transition from self-harm to suicidal behaviours was linked to experiencing major stressful life events and the use of severe methods of self-harm.

CONCLUSIONS

The findings suggest that socio-cultural factors impact mental health and recovery processes among South Asians. Mental health services should consider improving culturally sensitive clinical practices in responding to self-harm among South Asian communities.

Suicidal Ideation in American Indian and Alaskan Native College-Attending Students

INTRODUCTION

Despite being at the highest risk of suicide, American Indian/Alaskan Native (AIAN)-emerging adults are underrepresented in mental health research. There is great diversity in individual and community experiences and access within AIAN-identifying individuals, prompting the need for research on risk and protective factors of suicidality within AIAN-emerging adults.

METHODS

Data from AIAN-identifying emerging adults (mean age = 24.4 years) collected between 2017 and 2020 (n=2,551) were drawn from the Healthy Minds Study, a national annual panel study on mental/behavioral health within higher education settings. Multivariate logistic regressions (conducted in 2022) were used to evaluate the risk and protective factors associated with suicidality (ideation, planning, attempt) by gender (male, female, trans/gender nonbinary).

RESULTS

Suicidal ideation rates were high; over 1 in 5 AIAN-emerging adults reported ideation, 1 in 10 reported planning, and 3% reported attempt in the previous year. AIANs identifying as a gender minority (trans/nonbinary) were 3 times more likely to report suicidality across event type. Across all gender identities, suicidality was significantly associated with nonsuicidal self-injury and self-perceived need for help; flourishing was predictive of lower odds of suicidality event for male- and female-identifying AIAN students.

CONCLUSIONS

Suicidality is high for AIAN college-attending students, particularly for gender minority-identifying students. Embracing a strength-based approach to highlight student awareness of mental health services is critical. Future research should examine the protective factors as well as community and structural factors that might provide meaningful support within and outside of university contexts for students facing individual, relational, or challenges within their communities.

The role of anxiety and depression in suicidal thoughts for autistic and non-autistic people: A theory-driven network analysis

BACKGROUND

Autistic adults experience more frequent suicidal thoughts and mental health difficulties than non-autistic adults, but research has yet to explain how these experiences are connected. This study explored how anxiety and depression contribute to suicidal thoughts according to the Interpersonal Theory of Suicide for autistic and non-autistic adults.

METHODS

Participants (autistic adults n = 463, 61% female; non-autistic n = 342, 64% female) completed online measures of anxiety, depression, thwarted belonging, and perceived burdensomeness. Network analysis explored whether: (i) being autistic is a risk marker for suicide; and (ii) pathways to suicidal thoughts are consistent for autistic and non-autistic adults.

RESULTS

Being autistic connected closely with feeling like an outsider, anxiety, and movement, which connected to suicidal thoughts through somatic experiences, low mood, and burdensomeness. Networks were largely consistent for autistic and non-autistic people, but connections from mood symptoms to somatic and thwarted belonging experiences were absent for autistic adults.

CONCLUSION

Autistic people experience more life stressors than non-autistic people leading to reduced coping, low mood, and suicidal thoughts. Promoting belonging, reducing anxiety, and understanding the role of movement could inform suicide prevention for autistic people. Research should accurately capture autistic lived experience when modeling suicide to ensure suicide prevention meets autistic needs.

Longitudinal patterns and predictors of suicidal ideation in African American adolescents

Suicide rates among African American adolescents have increased dramatically. Suicidal ideation is associated with both suicide attempts and completions, thus understanding ideation patterns and predictors in African American adolescents is critical to informing prevention efforts. This study recruited 160 African American ninth grade students. Participants were those students randomized to the control condition of a randomized controlled preventive intervention. Of the 160 participants, 99 completed all assessment points and were included in latent transition analyses. We assessed participants four times: baseline then again at 6-, 12-, and 18-month postbaseline. Constructs of interest for this study included suicidal ideation, depression, hopelessness, and community violence exposure. A 2-class model (i.e., low ideation [LI] and high ideation [HI]) characterized ideation at each time point. A total of 86%-90% of participants were in the LI class in any given time point and 27.3% of participants were in the HI class at least once. Participants in the LI class tended to stay in that class, whereas those in the HI class often transitioned to the LI group. Depression and hopelessness, but not exposure to community violence, predicted HI class membership. Findings suggest that (a) most African American adolescents may experience suicide ideation at some point in time, (b) a concerning proportion of African American adolescents may experience high ideation, (c) high ideation is often time-limited, and (d) depression and hopelessness predict high ideation.

Suicidal behavior among inpatients with severe mental conditions in a public mental health hospital in Uganda

BACKGROUND

Suicidal behaviors are prevalent among inpatients with severe mental conditions and may result in many dying by suicide. Few studies have focused on the burden of suicidal behaviors among these inpatients in low-income settings, despite suicide being consistently higher in lower-income countries such as Uganda. This study, therefore, provides the prevalence and associated factors of suicidal behaviors and suicide attempts among inpatients with severe mental conditions in Uganda.

METHOD

This was a retrospective chart review of all individuals admitted with severe mental conditions to a large psychiatry inpatient unit in Uganda for four years (2018-2021). Two separate logistic regressions were conducted to determine the factors associated with suicidal behaviors or suicidal attempts among the admitted individuals.

RESULTS

The prevalence of suicidal behavior and suicidal attempts among 3104 (mean age = 33, Standard deviation [SD] = 14.0; 56% were males) were 6.12% and 3.45%, respectively. Having a diagnosis of depression increased the likelihood of both suicidal behaviors (adjusted odds ratio [aOR]: 5.36; 95% confidence interval [CI]: 2.14-13.37; p =0.001) and attempts (aOR: 10.73; 95% CI: 3.44-33.50; p < 0.001). However, a diagnosis of substance-related disorder increased the likelihood of having attempted suicide (aOR: 4.14; 95% CI: 1.21-14.15; p = 0.023). The likelihood of having suicidal behavior decreased as one increased in age (aOR: 0.97; 95% CI: 0.94-0.99; p = 0.006) and increased among individuals reporting stress from financial constraints (aOR: 2.26; 95% CI: 1.05-4.86; p = 0.036).

CONCLUSION

Suicidal behaviors are common among inpatients managed for severe mental health conditions in Uganda, especially those with substance use and depressive disorders. In addition, financial stressors are a main predictor in this low-income country. Therefore, regular screening for suicide behaviors is warranted, especially among individuals with depression, and substance use, among those who are young, and among those reporting financial constraints/stress.

Suicide ideation among Brazilian college students: Relationship with academic factors, mental health, and sexual abuse

BACKGROUND

Suicide is one of the leading causes of death among youth and its occurrence among college students is a matter of great concern. Challenges of transitional adulting and mental illness increase the likelihood of suicidal cognition in students. The objective of present study was to investigate the prevalence of suicide ideation and associated factors in a representative sample of Brazilian college students (n = 12,245).

METHODS

Data were drawn from a nationwide survey and further subjected to estimate the prevalence of suicide ideation and its association with socio-demographic and academic characteristics. We performed logistic regression analyses upon a conceptual framework, considering individual and academic factors.

RESULTS

The point-prevalence of suicide ideation among college students was 5.9 % (SE = 0.37). In the final regression model, variables associated with the likelihood of suicide ideation were psychopathology, sexual abuse, and academic variables, such as dissatisfaction with the chosen undergraduate course (OR = 1.86; IC95 % 1.43-2.41) and low academic performance (OR = 3.56; IC95 % 1.69-7.48). Having children and religious affiliation were inversely associated with the likelihood of suicide ideation.

LIMITATIONS

Participants were recruited from state capitals, which limited data generalizability to non-urban college students.

CONCLUSIONS

The impact of academic life on the mental health of students should be carefully monitored in in-campus pedagogical and health services. Early identification of poor-performance students with social disadvantages could indicate vulnerable ones who are much in need of psycho-social support.

Premature mortality in young people accessing early intervention youth mental healthcare: data-linkage cohort study

BACKGROUND

Understanding premature mortality risk from suicide and other causes in youth mental health cohorts is essential for delivering effective clinical interventions and secondary prevention strategies.

AIMS

To establish premature mortality risk in young people accessing early intervention mental health services and identify predictors of mortality.

METHOD

State-wide data registers of emergency departments, hospital admissions and mortality were linked to the Brain and Mind Research Register, a longitudinal cohort of 7081 young people accessing early intervention care, between 2008 and 2020. Outcomes were mortality rates and age-standardised mortality ratios (SMR). Cox regression was used to identify predictors of all-cause mortality and deaths due to suicide or accident.

RESULTS

There were 60 deaths (male 63.3%) during the study period, 25 (42%) due to suicide, 19 (32%) from accident or injury and eight (13.3%) where cause was under investigation. All-cause SMR was 2.0 (95% CI 1.6-2.6) but higher for males (5.3, 95% CI 3.8-7.0). The mortality rate from suicide and accidental deaths was 101.56 per 100 000 person-years. Poisoning, whether intentional or accidental, was the single greatest primary cause of death (26.7%). Prior emergency department presentation for poisoning (hazard ratio (HR) 4.40, 95% CI 2.13-9.09) and psychiatric admission (HR 4.01, 95% CI 1.81-8.88) were the strongest predictors of mortality.

CONCLUSION

Premature mortality in young people accessing early intervention mental health services is greatly increased relative to population. Prior health service use and method of self-harm are useful predictors of future mortality. Enhanced care pathways following emergency department presentations should not be limited to those reporting suicidal ideation or intent.

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

BACKGROUND

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

METHODS

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

RESULTS

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

CONCLUSION

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

The Mental Imagery for Suicidality in Students Trial (MISST): study protocol for a feasibility randomised controlled trial of broad-minded affective coping (BMAC) plus risk assessment and signposting versus risk assessment and signposting alone

BACKGROUND

Going to university is an important milestone in many people's lives. It can also be a time of significant challenge and stress. There are growing concerns about mental health amongst student populations including suicide risk. Student mental health and counselling services have the potential to prevent suicide, but evidence-based therapies are required that fit these service contexts. The Broad-Minded Affective Coping intervention (BMAC) is a brief (6 sessions), positive imagery-based intervention that aims to enhance students access to past positive experiences and associated emotions and cognitions. Pilot data provides preliminary support for the BMAC for students struggling with suicidal thoughts and behaviours, but this intervention has not yet been evaluated in the context of a randomised controlled trial (RCT). The Mental Imagery for Suicidality in Students Trial (MISST) is a feasibility RCT that aims to determine the acceptability and feasibility of evaluating the BMAC as an intervention for university students at risk of suicide within a larger efficacy trial. Key feasibility uncertainties have been identified relating to recruitment, retention, and missing data. Intervention acceptability and safety will also be evaluated.

METHOD

MISST is a feasibility randomised controlled trial design, with 1:1 allocation to risk assessment and signposting plus BMAC or risk assessment and signposting alone. Participants will be university students who self-report experiences of suicidal ideation or behaviour in the past 3 months. Assessments take place at baseline, 8, 16, and 24 weeks. The target sample size is 66 participants. A subset of up to 20 participants will be invited to take part in semi-structured qualitative interviews to obtain further data concerning the acceptability of the intervention.

DISCUSSION

The BMAC intervention may provide an effective, brief talking therapy to help university students struggling with suicidal thoughts that could be readily implemented into university student counselling services. Depending on the results of MISST, the next step would be to undertake a larger-scale efficacy trial.

TRIAL REGISTRATION

The trial was preregistered (17 December 2021) on ISRCTN (ISRCTN13621293) and ClinicalTrials.gov (NCT05296538).
