“Validation of three scales for enhanced suicide prevention in Spanish-speaking populations: Suicidal ideation, stigma, and literacy”

BackgroundEscalating suicide rates in Spain and Latin America underscore the critical need for accurate assessment and prevention tools tailored to these populations. This study aimed to culturally adapt and validate three essential scales: the Suicidal Ideation Attributes Scale (SIDAS), the Suicide Stigma Scale - Short Form (SOSS-SF), and the Suicide Literacy Scale - Short Form (LOSS-SF). MethodA total of 678 participants (including 150 with suicidal ideation) completed an online survey. The scales underwent rigorous back-translation and adaptation by native speakers from Spain and Latin America. SIDAS and SOSS-SF were validated using Confirmatory Factor Analysis (CFA), with criteria including fit indices (e.g., RMSEA, CFI). LOSS-SF underwent validation through Item Response Theory (IRT). Additionally, gender invariance was assessed across all scales. ResultsCFA confirmed the original factor structures of SIDAS and SOSS-SF, demonstrating good fit indices and internal consistency. The analysis of LOSS-SF required excluding two items, resulting in a final Spanish version with 10 items and an unifactorial structure. Gender invariance was established across all scales. ConclusionsThe culturally adapted and validated scales in this study demonstrate robust reliability and validity for assessing suicidal ideation, suicide stigma, and suicide literacy among Spanish-speaking populations. These validated tools have the potential to enhance clinical assessment, inform personalized interventions, monitor public health initiatives, educate communities about suicide, and advance research in suicide prevention and treatment.

Brief online suicide risk assessment of adults does not affect state mood, even in the context of elevated suicidality self-stigma, suicidal ideation and psychological distress.

The current study aimed to assess whether online suicide risk assessment affects state mood and is the first to examine if suicide-related self-stigma or coping related to suicidal ideation are predictors of mood change. The Australian participants (N = 661, Mage = 34.9, SD = 12.3, 57.1% female), recruited through a crowd-sourcing platform, completed a visual analogue mood measure before and after the Suicidal Ideation Attributes Scale (SIDAS), an assessment tool. Followed by a modified version of the Internalised Stigma Scale, the Brief COPE and DASS-21. State mood did not change from pre- to post-suicide risk assessment in the overall sample, t(662) = -.16, p = .868, d = -.01. Contrary to hypotheses, neither self-stigma nor coping were related to mood change following exposure to the SIDAS. The multiple regression model was not significant, F(9,643) = 1.16, p = .31., nor was any single predictor including gender, current Suicide risk β = -.04, t = -.80 or psychological distress β = -.09, t = -1.76, p = .08. These findings suggest that online exposure to a suicide risk tool is unlikely to be iatrogenic in relation to state mood, even in the context of elevated self-stigma, suicidal ideation and psychological distress.

Savižudiškų minčių intensyvumo skalė (SIDAS) ir Savižudiško elgesio klausimynas – patikslintas (SBQ-R): lietuviškų versijų psichometriniai rodikliai

The Suicidal Ideation Attributes Scale (SIDAS) and the Suicidal Behaviors Questionnaire-Revised (SBQ-R) are widely used psychological instruments for assessing people‘s suicidal ideation and suicidal behavior. The aim of this study was to examine the psychometric characteristics of the Lithuanian versions of the SIDAS and SBQ-R. We analysed data collected from four samples: a Lithuanian general population quota sample based on age, gender and place of residence (N = 697, 52.9% women, aged 18–79 years); a sample of students (N = 2013, 72 % women, aged 18–29 years); a clinical sample of suicidal patients (N = 35, 77.1% women, aged 18–59 years); and a test-retest sample of students who completed the instruments twice within a two-week period (N = 54, 70.4% women, aged 18–47 years). The participants answered questions on gender, and age and completed the SIDAS and SBQ-R. The data analysis revealed that the Lithuanian versions of the SIDAS and SBQ-R have good internal consistency, temporal stability, construct, convergent, and criterion validity. The Lithuanian versions of the SIDAS and SBQ-R can be used to measure suicidality in research settings, as well as in clinical work as auxiliary tools.

Suicide and depressive symptoms possible correlates among a sample of Egyptian physicians: observational cross-sectional study (online survey)

BackgroundCompared to other occupations, physicians are more susceptible to depression and suicide. Suicide among physicians in some countries reached up to 1.5- to threefold higher than the general population. However, this rate was not homogenous in all countries. Most of the Egyptian studies were related to the stressful pandemic event, but the actual prevalence of depression among physicians is still under research. To the best of the researcher's knowledge, no other study has been conducted to evaluate the risk of suicide among Egyptian physicians.AimThe study aimed to screen for depressive symptoms and suicide among Egyptian physicians and to investigate the correlates associated with suicide ideations.MethodsThis cross-sectional survey included Egyptian physicians recruited online by Google Forms. Depressive symptoms were screened using the Beck Depression Scale (BDI-II), while suicidal ideas were assessed using the Suicidal Ideation Attributes Scale (SIDAS). ResultsSix hundred sixty Egyptian physicians completed the survey following a two-week pilot study between January 10 and July 16, 2023. The average age was 39.1 years, and 71.4% were married. 49.1% were medical specialists. The median daily working hours were eight, and 27.7% of the physicians attended night shifts. 22.3% had a psychiatric illness, and 34.3% had a chronic disease. Younger and single physicians of both sexes were more prone to suicide risk (p-value = 0.019 and 0.021, respectively). Those with psychiatric or chronic medical disorders had a higher suicidal risk (p-values < 0.001 and 0.004, respectively). Physicians with fewer academic degrees and those who work longer hours or night shifts had more depressive symptoms (p-values < 0.001 and 0.009, respectively). The risk of depression and suicide is almost the same in all medical specialties. The SIDAS suicide score and the Beck depression score revealed a statistically significant association (r = 0.288, p-value < 0.001).ConclusionSuicide risk is higher among younger, single physicians of both sexes, as well as those with psychiatric or chronic medical disorders. More depressive symptoms are seen in physicians who have more extended hours or night shifts and who have fewer academic degrees. Almost all medical specialties carry the same risk of depression and suicide. Longitudinal research is recommended for regular follow-up of suicidal thoughts and depressive symptoms.

OR31-04 Testosterone Therapy On Gender Dysphoria, Depression, And Suicidality In Transgender And Gender Diverse Individuals Seeking Masculinisation: A Randomised Controlled Trial

Abstract Disclosure: B.J. Nolan: None. S. Zwickl: None. J.D. Zajac: None. A.S. Cheung: None. Background: Testosterone treatment is a necessary component of management for some transgender (trans) and gender diverse individuals. Observational studies have demonstrated improvements in gender dysphoria and depression following commencement of gender-affirming hormone therapy but there is a lack of randomised controlled trial data. Objectives: To assess the impact of testosterone therapy compared to no treatment on gender dysphoria, depression, and suicidality in trans people seeking masculinisation. Methods: Three-month open-label randomised controlled trial of 64 trans individuals seeking initiation of testosterone therapy comparing immediate testosterone commencement (intervention group) with no treatment (standard care waiting list of 3 months prior to commencement). This design ensured no individuals would be waiting longer than standard care. Primary outcome was gender dysphoria, as measured by the Gender Preoccupation and Stability Questionnaire (GPSQ). Secondary outcomes included the Patient Health Questionnaire-9 (PHQ-9) to assess depression and the Suicidal Ideation Attributes Scale (SIDAS) to assess suicidality. Questionnaires were undertaken at 0 and 3 months. ANCOVA was used to compare mean differences between groups. Results: Compared to standard care, the intervention group had a decrease in gender dysphoria [mean difference -7.2 points (95% CI (-8.3, -6.1), p&amp;lt;0.001], a clinically significant decrease in PHQ-9 [mean difference -5.6 points (-6.8, -4.4), p&amp;lt;0.001], and a decrease in SIDAS [mean difference -6.5 points (-8.2, -4.8), p&amp;lt;0.001]. Resolution of suicidality assessed by PHQ-9 item 9 occurred in 11 (52%) individuals with immediate testosterone commencement compared to 1 (5%) in standard care (p=0.002). Conclusions: This randomised controlled trial supports the use of testosterone therapy to significantly reduce gender dysphoria, depression, and suicidality in trans and gender diverse individuals desiring testosterone therapy.

Early Access to Testosterone Therapy in Transgender and Gender-Diverse Adults Seeking Masculinization

Testosterone treatment is a necessary component of care for some transgender and gender-diverse individuals. Observational studies have reported associations between commencement of gender-affirming hormone therapy and improvements in gender dysphoria and depression, but there is a lack of data from randomized clinical trials. To assess the effect of testosterone therapy compared with no treatment on gender dysphoria, depression, and suicidality in transgender and gender-diverse adults seeking masculinization. A 3-month open-label randomized clinical trial was conducted at endocrinology outpatient clinics and primary care clinics specializing in transgender and gender-diverse health in Melbourne, Australia, from November 1, 2021, to July 22, 2022. Participants included transgender and gender-diverse adults aged 18 to 70 years seeking initiation of testosterone therapy. Immediate initiation of testosterone commencement (intervention group) or no treatment (standard care waiting list of 3 months before commencement). This design ensured no individuals would be waiting longer than the time to standard care. The primary outcome was gender dysphoria, as measured by the Gender Preoccupation and Stability Questionnaire. Secondary outcomes included the Patient Health Questionnaire-9 (PHQ-9) to assess depression and the Suicidal Ideation Attributes Scale (SIDAS) to assess suicidality. Questionnaires were undertaken at 0 and 3 months. The evaluable cohort was analyzed. Sixty-four transgender and gender-diverse adults (median [IQR] age, 22.5 [20-27] years) were randomized. Compared with standard care, the intervention group had a decrease in gender dysphoria (mean difference, -7.2 points; 95% CI, -8.3 to -6.1 points; P < .001), a clinically significant decrease in depression (ie, change in score of 5 points on PHQ-9; mean difference, -5.6 points; 95% CI, -6.8 to -4.4 points; P < .001), and a significant decrease in suicidality (mean difference in SIDAS score, -6.5 points; 95% CI, -8.2 to -4.8 points; P < .001). Resolution of suicidality assessed by PHQ-9 item 9 occurred in 11 individuals (52%) with immediate testosterone commencement compared with 1 (5%) receiving standard care (P = .002). Seven individuals reported injection site pain/discomfort and 1 individual reported a transient headache 24 hours following intramuscular administration of testosterone undecanoate. No individual developed polycythemia. In this open-label randomized clinical trial of testosterone therapy in transgender and gender-diverse adults, immediate testosterone compared with no treatment significantly reduced gender dysphoria, depression, and suicidality in transgender and gender-diverse individuals desiring testosterone therapy.

The Suicidal Intrusions Attributes Scale (SINAS): a new tool measuring suicidal intrusions.

Suicidal intrusions are uncontrollable, intrusive mental images (e. g., visualizing a future suicidal act). They may also be called suicidal "flash-forwards." Despite the importance of integrating the assessment of suicidal intrusions into a clinical routine assessment, quick self-report screening instruments are lacking. This study describes the development of a new instrument-Suicidal Intrusions Attributes Scale (SINAS)-to assess the severity and characteristics of suicidal intrusions and examines its psychometric properties. The sample included currently suicidal outpatients with elevated levels of depression recruited across mental health institutions in the Netherlands (N = 168). Instruments administered were 10-item SINAS, the Suicidal Ideation Attributes Scale (SIDAS), the Prospective Imagery Task (PIT), four-item Suicidal Cognitions Interview (SCI), and the Beck Depression Inventory (BDI-II). An exploratory factor analysis identified a one-factor structure. The resulting SINAS demonstrated good internal consistency (Cronbach's α = 0.91) and convergent validity, as expected. Overall, this study demonstrated acceptable levels of reliability and validity of the measure in a depressed clinical population with suicidal ideation. The SINAS may be a useful screening tool for suicidal intrusions in both research and clinical settings.

A pilot predictive model based on COVID-19 data to assess suicidal ideation indirectly

The COVID-19 pandemic has had a negative impact on the mental health of the population. Many studies reported high levels of psychological distress and rising rates of suicidal ideation (SI). Data on a range of psychometric scales from 1790 respondents were collected in Slovenia through an online survey between July 2020 and January 2021. As a worrying percentage (9.7%) of respondents reported having SI within the last month, the goal of this study was to estimate the presence of SI, as indicated by the Suicidal Ideation Attributes Scale (SIDAS). The estimation was based on the change of habits, demographic features, strategies for coping with stress, and satisfaction with three most important aspects of life (relationships, finances, and housing). This could both help recognize the telltale factors indicative of SI and potentially identify people at risk. The factors were specifically selected to be discreet about suicide, likely sacrificing some accuracy in return. We tried four machine learning algorithms: binary logistic regression, random forest, XGBoost, and support vector machines. Logistic regression, random forest, and XGBoost models achieved comparable performance with the highest area under the receiver operating characteristic curve of 0.83 on previously unseen data. We found an association between various subscales of Brief-COPE and SI; Self-Blame was especially indicative of the presence of SI, followed by increase in Substance Use, low Positive Reframing, Behavioral Disengagement, dissatisfaction with relationships and lower age. The results showed that the presence of SI can be estimated with reasonable specificity and sensitivity based on the proposed indicators. This suggests that the indicators we examined have a potential to be developed into a quick screening tool that would assess suicidality indirectly, without unnecessary exposure to direct questions on suicidality. As with any screening tool, subjects identified as being at risk, should be further clinically examined.

Suicide literacy and attitudes toward psychological help-seeking: a cross-sectional study of students.

Higher education students express high levels of suicidal ideation. However, data on students' knowledge of suicide and attitudes toward seeking professional psychological help are lacking. Therefore, a cross-sectional study was conducted to evaluate students' suicidal ideation, suicide literacy and attitudes toward seeking professional psychological help, and to assess whether these variables were interrelated. Higher education students completed an online survey that consisted of 12 questions on suicide literacy (based on the Literacy of Suicide Scale), the Attitudes Toward Seeking Professional Psychological Help Scale and the Suicidal Ideation Attributes Scale. A total of 2004 students completed the survey. Female students and biomedical students showed the highest suicide literacy and most positive help-seeking attitudes. Higher study year was associated with more positive help-seeking attitudes. Art students expressed the highest levels of suicidal ideation. Suicide literacy had a weak positive correlation with help-seeking attitudes (Spearman's rho = 0.186). Suicidal ideation, suicide literacy and help-seeking attitudes may differ according to student's gender, study year and study field. Better suicide literacy may promote psychological help-seeking behavior.

Breaking Down Barriers to a Suicide Prevention Helpline: Protocol for a Web-Based Randomized Controlled Trial.

Globally, suicide is among the leading causes of death, with men being more at risk to die from suicide than women. Research suggests that people with suicidal ideation often struggle to find adequate help. Every month, around 4000 people fill in the anonymous self-test for suicidal thoughts on the website of the Dutch suicide prevention helpline. This self-test includes the Suicidal Ideation Attributes Scale (SIDAS), which educates users about the severity of their suicidal thoughts. The vast majority (70%) of people who complete the self-test score higher than the cutoff point (≥21) for severe suicidal thoughts. Unfortunately, despite this, less than 10% of test-takers navigate to the web page about contacting the helpline. This protocol presents the design of a web-based randomized controlled trial that aims to reduce barriers to contacting the suicide prevention helpline. The aim of this study is 2-fold: (1) to measure the effectiveness of a brief barrier reduction intervention (BRI) provided in the self-test motivating people with severe suicidal thoughts to contact the Dutch suicide prevention helpline and (2) to specifically evaluate the effectiveness of the BRI in increasing service use by high-risk groups for suicide such as men and middle-aged people. People visiting the self-test for suicidal thoughts on the website of the suicide prevention helpline will be asked to participate in a study to improve the self-test. Individuals with severe suicidal thoughts and little motivation to contact the helpline will be randomly allocated either to a brief BRI, in which they will receive a short tailored message based on their self-reported barrier to the helpline (n=388) or care as usual (general advisory text, n=388). The primary outcome measure is the use of a direct link to contact the helpline after receiving the intervention or control condition. Secondary outcomes are the self-reported likelihood of contacting the helpline (on a 5-point scale) and satisfaction with the self-test. In the BRI, participants receive tailored information to address underlying concerns and misconceptions of barriers to the helpline. A pilot study was conducted among current test-takers to identify these specific barriers. The pilot study (N=1083) revealed multiple barriers to contacting the helpline. The most prominent were the belief that a conversation with a counselor would not be effective, fear of the conversation itself, and emotional concerns about talking about suicidal thoughts. Our study will provide insight into the effectiveness of a brief BRI designed to increase the use of a suicide prevention helpline provided in a self-test on suicidal thoughts. If successful, this intervention has the potential to be a low-cost, easily scalable, and feasible method to increase service use for helplines across the world.

Trauma-related guilt as a mediator between post-traumatic stress disorder and suicidal ideation.

As a mental health issue, suicide is a growing global concern, with patients who have post-traumatic stress disorder (PTSD) being at particularly high risk. This study aimed to investigate whether the link between PTSD and suicidal ideation is mediated by trauma-related guilt. Data were obtained from Wave 1, Time 1 (November 2016), and Time 2 (March 2017) of the National Survey for Stress and Health (NSSH) in Japan. The NSSH is an online longitudinal survey conducted on Japan's national population aged 18 years and older. The cumulative response rate of the survey was 66.7% at Time 2. A total of 1,005 patients with PTSD were included for analyses. The severity of PTSD symptoms was assessed with PTSD DSM-5 Checklist, and the trauma-related guilt were assessed using the two subscales (hindsight-bias/responsibility and global guilt scale) of the trauma-related guilt inventory (TRGI). Suicidal ideation was evaluated using the suicidal ideation attributes scale (SIDAS). Pearson's correlation was used to investigate the associations among PTSD symptoms, TRGI scores, and SIDAS scores. Causal mediation analysis was applied to evaluate the causal relationship between PTSD, trauma-related guilt, and suicidal ideation. Pearson's correlation did not show patients' age, gender, and household income significantly associated with SIDAS scores. On the other hand, severities of PTSD symptoms (r = 0.361, p < 0.001) and trauma-related guilt (r = 0.235, p < 0.001) were positively associated with SIDAS scores. After adjusting for age, gender, and household income, the mediation analysis revealed that trauma-related guilt significantly mediates the effects of PTSD symptoms on suicidal ideation. Our results implied that trauma-related guilt may represent a critical link between PTSD and suicidal ideation, which may be a noteworthy target for therapeutic intervention.

The impact of COVID-19 pandemic on the healthcare workers mental health

IntroductionThe COVID-19 pandemic represents an unprecedented in health events that has had a negative impact on the mental health of the population in general as well as on specific categories, including patients with mental and physical disorders, and healthcare professionals. In particular, COVID-19 pandemic has produced extraordinary stress in healthcare workers, especially frontline physicians, nurses and healthcare professionals.ObjectivesIn the present study we aimed to evaluate levels of burnout, a clinical condition characterized by emotional, psychological and physical exhaustion, in a sample of health workers from the Campania region, Italy, during the first phase of the COVID-19 pandemic. Secondary objectives of the study include the assessment, in the same group, of levels of anxiety-depressive symptoms, insomnia, suicidal ideation and symptoms on the post-traumatic spectrum.MethodsAn online survey was released through the official website of the University of Campania “L. Vanvitelli” and social media. The Maslach Burnout Inventory was used to assess burnout in the healthcare professionals; Depression Anxiety Stress Scale-21 Short Version to measure levels of anxiety, depression and stress; the Insomnia Severity Index was used to identify insomnia-related symptoms; the Suicidal Ideation Attributes Scale was adopted to select individuals based on the presence of suicidal thoughts while the Impact of Event Scale-Revised was administered to evaluate trauma-related dimensions.ResultsA total of 389 health workers was recruited. They were predominantly female, with an average age of 39.06 (± 11.85) years, working mainly in the second line hospitals during the COVID-19 emergency. During the pandemic, first- or second-line health workers reporting significant levels of emotional exhaustion are on average 23,89 (±4.22), those reporting feelings of depersonalization are on average 7.58 (±2.73), while those who report a good level of professional efficiency are on average 21.12 (±3.48).Predictors of increased levels of depersonalization are being a first-line worker and the presence of traumatic event avoidance symptoms. Furthermore, levels of professional fulfillment are negatively affected by age, the presence of intrusive symptoms, the presence of sleep disorders, and being a frontline worker.ConclusionsThe impact of the COVID-19 pandemic on the mental health of healthcare professionals involved in the first and/or second line COVID hospitals is indisputable. Although burnout syndrome is not a new clinical condition, the COVID-19 pandemic may further worsen the magnitude of the problem. However, our results could be a starting point to promote a change in the way we perceive the mental health of healthcare professionals.Disclosure of InterestNone Declared

The Roles of Endorsement and Stigma in Suicidal Ideation and Behavior among Chinese College Students

Previous studies have suggested that stereotypes towards suicide, including endorsement of suicide and stigma toward suicide, may contribute to suicidal ideation and behaviors. However, this has not been examined directly. In this study, we examined whether endorsement of suicide and stigma toward suicide are involved in the pathway from suicidal ideation to suicide attempts among college students. To this end, we used the Suicidal Ideation Attributes Scale (SIDAS), the Suicidal Behaviors Questionnaire-Revised (SBQ-R), and the Stigma of Suicide Scale (SOSS) to assess suicidal ideation, suicide attempts, endorsement of suicide, and stigma toward suicide, respectively, in a sample of 944 Chinese college students (mean age, 20.97 years). Using mediation analysis, we found that suicidal ideation partially mediated the relationship between endorsement of suicide and suicide attempts and between stigma toward suicide and suicide attempts. These findings provide novel evidence that endorsement of suicide and stigma toward suicide are closely associated with suicide attempts, but partially through the influences of suicidal ideation. Future studies should elaborate on their longitudinal relationships. Implications of these findings for clinical practices are discussed with reference to the ideation-to-action framework of suicide, aiming to reduce suicidal behaviors.

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

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

The Gender Paradox: Understanding the Role of Masculinity in Suicidal Ideation.

It is important to understand the role of social determinants, such as gender, in suicidal ideation. This study examined whether conformity to specific masculine norms, particularly high self-reliance and emotional self-control, moderated the relationship between psychological distress and suicidal ideation for men. The other norms explored were those pertaining to behavioral–emotional or social hierarchy status aspects of masculinity, and whether they moderated the psychological distress–suicidal ideation relationship for men and women. The Conformity to Masculine Norms Inventory, the Kessler Psychological Distress Scale, and the Suicidal Ideation Attributes Scale were administered to an Australian community sample in an online survey (n = 486). As predicted, higher psychological distress was associated with higher suicidal ideation. Self-reliance enhanced the relationship and was the only moderator among men. High self-reliance levels might be an important indicator of risk, which can be used when assessing and working with men who are hesitant to openly discuss suicidal ideation with clinicians. For female participants, higher endorsement of behavioral–emotional norms and lower conformity to social hierarchy status norms appear to increase suicide risk in the presence of psychological distress. Our findings suggest that high self-reliance is of particular concern for men experiencing psychological distress. It is also important to consider the roles of masculine norm endorsement in the psychological distress–suicidal ideation relationship among women.

A machine-learning model to predict suicide risk in Japan based on national survey data.

ObjectiveSeveral prognostic models of suicide risk have been published; however, few have been implemented in Japan using longitudinal cohort data. The aim of this study was to identify suicide risk factors for suicidal ideation in the Japanese population and to develop a machine-learning model to predict suicide risk in Japan.Materials and MethodsData was obtained from Wave1 Time 1 (November 2016) and Time 2 (March 2017) of the National Survey for Stress and Health in Japan, were incorporated into a suicide risk prediction machine-learning model, trained using 65 items related to trauma and stress. The study included 3,090 and 2,163 survey respondents >18 years old at Time 1 and Time 2, respectively. The mean (standard deviation, SD) age was 44.9 (10.9) years at Time 1 and 46.0 (10.7) years at Time 2. We analyzed the participants with increased suicide risk at Time 2 survey. Model performance, including the area under the receiver operating characteristic curve (AUC), sensitivity, and specificity, were also analyzed.ResultsThe model showed a good performance (AUC = 0.830, 95% confidence interval = 0.795–0.866). Overall, the model achieved an accuracy of 78.8%, sensitivity of 75.4%, specificity of 80.4%, positive predictive value of 63.4%, and negative predictive value of 87.9%. The most important risk factor for suicide risk was the participants' Suicidal Ideation Attributes Scale score, followed by the Sheehan Disability Scale score, Patient Health Questionnaire-9 scores, Cross-Cutting Symptom Measure (CCSM-suicidal ideation domain, Dissociation Experience Scale score, history of self-harm, Generalized Anxiety Disorder-7 score, Post-Traumatic Stress Disorder check list-5 score, CCSM-dissociation domain, and Impact of Event Scale-Revised scores at Time 1.ConclusionsThis prognostic study suggests the ability to identify patients at a high risk of suicide using an online survey method. In addition to confirming several well-known risk factors of suicide, new risk measures related to trauma and trauma-related experiences were also identified, which may help guide future clinical assessments and early intervention approaches.

The effect of a therapeutic smartphone application on suicidal ideation in young adults: Findings from a randomized controlled trial in Australia.

BackgroundSuicidal ideation is a major risk for a suicide attempt in younger people, such that reducing severity of ideation is an important target for suicide prevention. Smartphone applications present a new opportunity for managing ideation in young adults; however, confirmatory evidence for efficacy from randomized trials is lacking. The objective of this study was to assess whether a therapeutic smartphone application (“LifeBuoy”) was superior to an attention-matched control application at reducing the severity of suicidal ideation.Methods and findingsIn this 2-arm parallel, double-blind, randomized controlled trial, 455 young adults from Australia experiencing recent suicidal ideation and aged 18 to 25 years were randomly assigned in a 2:2 ratio to use a smartphone application for 6 weeks in May 2020, with the final follow-up in October 2020. The primary outcome was change in suicidal ideation symptom severity scores from baseline (T0) to postintervention (T1) and 3-month postintervention follow-up (T2), measured using the Suicidal Ideation Attributes Scale (SIDAS). Secondary outcomes were symptom changes in depression (Patient Health Questionnaire-9, PHQ-9), generalized anxiety (Generalized Anxiety Disorder-7, GAD-7), distress (Distress Questionnaire-5, DQ5), and well-being (Short Warwick–Edinburgh Mental Well-Being Scale, SWEMWBS). This trial was conducted online, using a targeted social media recruitment strategy. The intervention groups were provided with a self-guided smartphone application based on dialectical behavior therapy (DBT; “LifeBuoy”) to improve emotion regulation and distress tolerance. The control group were provided a smartphone application that looked like LifeBuoy (“LifeBuoy-C”), but delivered general (nontherapeutic) information on a range of health and lifestyle topics. Among 228 participants randomized to LifeBuoy, 110 did not complete the final survey; among 227 participants randomized to the control condition, 91 did not complete the final survey. All randomized participants were included in the intent-to-treat analysis for the primary and secondary outcomes. There was a significant time × condition effect for suicidal ideation scores in favor of LifeBuoy at T1 (p < 0.001, d = 0.45) and T2 (p = 0.007, d = 0.34). There were no superior intervention effects for LifeBuoy on any secondary mental health outcomes from baseline to T1 or T2 [p-values: 0.069 to 0.896]. No serious adverse events (suicide attempts requiring medical care) were reported.The main limitations of the study are the lack of sample size calculations supporting the study to be powered to detect changes in secondary outcomes and a high attrition rate at T2, which may lead efficacy to be overestimated.ConclusionsLifeBuoy was associated with superior improvements in suicidal ideation severity, but not secondary mental health outcomes, compared to the control application, LifeBuoy-C. Digital therapeutics may need to be purposefully designed to target a specific health outcome to have efficacy.Trial registrationAustralian New Zealand Clinical Trials Registry ACTRN12619001671156

Influence of suicidality on adult perceptions of COVID-19 risk and guideline adherence

BackgroundSuicide rates have been increasing for decades, and the challenges of a global pandemic seem to have worsened suicide risk factors. The relationship between suicidality, COVID-19 risk perceptions, and guideline adherence was examined to inform potential barriers to the implementation of behavioral interventions aimed at preventing future pandemics. MethodsA national sample of 159 MTurk participants (Mage = 37.64 years, SD = 11.92; 48.4% female) completed an online survey containing the following: demographics, Suicidal Ideation Attributes Scale, Broadly Applicable Measure of Risk Perception of COVID-19, and Adherence to COVID-19 Guidelines and Perceived Risk Scale. ResultsMultiple linear regressions assessed how suicidality related to perceived risk subscales and each adherence indicator while controlling for biological sex, age, and essential worker status. Over 25% of participants reported suicidality over the past month, and 19% were at high risk of suicidal behavior. Greater suicidality was associated with lower general COVID-19 risk perceptions (β = −0.326, p < .001), decreased handwashing (β = −0.423, p < .001), lower likelihood of planning to self-quarantine if infected with COVID-19 (β = −0.400, p < .001), less social distancing (β = −0.457, p < .001), and increased attendance of large gatherings (β = 0.405, p < .001). LimitationsTemporal relationships were unable to be assessed due to the cross-sectional nature of the data used. The low internal reliability of the risk probability subscale precluded its inclusion in analyses. ConclusionGiven suicidality's associations with decreased risk perceptions and low adherence, it may present as a barrier to the sustained behavior change that will be necessary in preventing the occurrence of future pandemics.

Measuring discrimination experienced by people with a mental illness: replication of the short-form DISCUS in six world regions.

The Discrimination and Stigma Scale (DISC) is a patient-reported outcome measure which assesses experiences of discrimination among persons with a mental illness globally. This study evaluated whether the psychometric properties of a short-form version, DISC-Ultra Short (DISCUS) (11-item), could be replicated in a sample of people with a wide range of mental disorders from 21 sites in 15 countries/territories, across six global regions. The frequency of experienced discrimination was reported. Scaling assumptions (confirmatory factor analysis, inter-item and item-total correlations), reliability (internal consistency) and validity (convergent validity, known groups method) were investigated in each region, and by diagnosis group. 1195 people participated. The most frequently reported experiences of discrimination were being shunned or avoided at work (48.7%) and discrimination in making or keeping friends (47.2%). Confirmatory factor analysis supported a unidimensional model across all six regions and five diagnosis groups. Convergent validity was confirmed in the total sample and within all regions [ Internalised Stigma of Mental Illness (ISMI-10): 0.28-0.67, stopping self: 0.54-0.72, stigma consciousness: -0.32-0.57], as was internal consistency reliability (α = 0.74-0.84). Known groups validity was established in the global sample with levels of experienced discrimination significantly higher for those experiencing higher depression [Patient Health Questionnaire (PHQ)-2: p < 0.001], lower mental wellbeing [Warwick-Edinburgh Well-being Scale (WEMWBS): p < 0.001], higher suicidal ideation [Beck Hopelessness Scale (BHS)-4: p < 0.001] and higher risk of suicidal behaviour [Suicidal Ideation Attributes Scale (SIDAS): p < 0.001]. The DISCUS is a reliable and valid unidimensional measure of experienced discrimination for use in global settings with similar properties to the longer DISC. It offers a brief assessment of experienced discrimination for use in clinical and research settings.

Psychometric properties of the Suicidal Ideation Attributes Scale (SIDAS) in a longitudinal sample of people experiencing non-affective psychosis

BackgroundSuicidal ideation is a key precursor for suicide attempts and suicide deaths. Performing routine screening of suicide precursors can help identify people who are at high risk of death by suicide. This is, arguably, an important suicide prevention effort. The aim of this study was to assess the validity, reliability, and factor structure of the Suicidal Ideation Attributes Scale (SIDAS) in a three-month longitudinal study with people with a diagnosis of schizophrenia or non-affective psychosis and experiences of suicidal ideation and/or behaviours. It was predicted that the SIDAS would have high internal consistency, test-retest reliability, convergent, discriminant and construct validity.MethodsNinety-nine participants experiencing psychosis completed the SIDAS at baseline and 89 participants completed it 3 months later. Additionally, participants completed a demographic questionnaire, the Beck Scale for Suicide Ideation, the Beck Hopelessness Scale, and the Defeat and Entrapment Scales. The internal consistency, test-retest reliability, convergent validity, and discriminant validity of the SIDAS were investigated in comparison to other constructs. Factor analysis was performed to examine the factor structure of the scale.ResultsPrincipal component analysis yielded a theoretically coherent one-dimensional factor structure of SIDAS, suggesting good construct validity (PCA = .71). The SIDAS had high internal consistency (α = .89) and good test-retest reliability (α = .73). It was highly correlated with other self-report measures, including the Beck Scale for Suicide Ideation, Beck Hopelessness Scale, Defeat and Entrapment scales, indicating excellent construct validity.ConclusionThe SIDAS is a valid and reliable self-report instrument for assessing the severity of suicidal ideation in a population of people with a diagnosis of schizophrenia or non-affective psychosis. Further research should test the psychometric properties of the scale in individuals experiencing different mental health problems in cross-cultural settings, in order to establish its broader validity, reliability, and clinical utility.
