The CDC reports that the United States has the highest suicide rates in over 80 years. Numerous public policies aimed at reducing the rising suicide rates, such as Aetna’s partnership with the American Foundation for Suicide Prevention (AFSP) and the zero-suicide initiative, continue to challenge these attempts. It, therefore, remains imperative to explore the shortcomings of these efforts that hamper their efficiency in reducing suicide rates. Advancements in research over time have sparked scientific skepticism, encouraging re-evaluation of established concepts. The current paper tests prevalent assumptions and arguments to uncover a scientifically informed approach to addressing rising suicide rates in clinical settings.

The Suicide Cognitions Scale (SCS) has demonstrated considerable promise as a risk screening tool, although it has yet to be validated for use with adolescents or in Spanish-speaking populations. The aim of this study was to develop a Spanish version of the 16-item SCS-Revised (SCS-R) and to examine its psychometric properties in a sample of adolescents. Participants were 172 adolescents aged between 12 and 18 years (M = 15.32, SD = 1.57) and currently in residential care. They completed the Spanish SCS-R and a series of other psychological measures. The psychometric properties of the SCS-R were examined through factor analyses and testing of convergent/discriminant validity and construct validity. Factor analyses supported a bifactor structure, indicating that SCS-R items were primarily measuring a common underlying latent variable. SCS-R scores were positively correlated with multiple indicators of psychopathology and other suicide risk factors (e.g., depression, hopelessness) but negatively correlated with protective factors (e.g., believing that one’s mental pain will eventually end). Importantly, SCS-R scores differentiated adolescents in residential care who had previously attempted suicide from those who had only thought about suicide. Scores also differentiated adolescents who had previously attempted suicide from those who had previously only engaged in non-suicidal self-injury. This constitutes further evidence that the SCS-R measures a construct that distinguishes suicidal thought from action and is specific to suicidal forms of self-harm. Overall, the results suggest that the Spanish SCS-R is a potentially useful tool for identifying adolescents at risk of attempting suicide in residential care.

Rising rates of suicide fatality, attempts, and ideations among adolescents aged 10–19 over the past two decades represent a national public health priority. Theories that seek to understand suicidal ideation overwhelmingly focus on the transition from ideation to attempt and on a sole cognition: active suicidal ideation – the serious consideration of killing one’s self, with less attention to non-suicidal cognitions that emerge during adolescence that may have implications for suicidal behavior. A large body of research exists that characterizes adolescence not only as a period of heightened onset and prevalence of active suicidal ideation and the desire to no longer be alive (i.e., passive suicidal ideation), but also for non-suicidal cognitions about life and death. Our review synthesizes extant literature in the content, timing and mental imagery of thoughts adolescents have about their (1) life; and (2) mortality that may co-occur with active and passive suicidal ideation that have received limited attention in adolescent suicidology. Our “cognition-to-action framework for adolescent suicide prevention” builds on existing ideation-to-action theories to identify life and non-suicidal mortality cognitions during adolescence that represent potential leverage points for the prevention of attempted suicide and premature death during this period and across the life span.

Suicide is a leading cause of death in the United States, particularly among adolescents. In recent years, suicidal ideation, attempts, and fatalities have increased. Systems maps can effectively represent complex issues such as suicide, thus providing decision-support tools for policymakers to identify and evaluate interventions. While network science has served to examine systems maps in fields such as obesity, there is limited research at the intersection of suicidology and network science. In this paper, we apply network science to a large causal map of adverse childhood experiences (ACEs) and suicide to address this gap. The National Center for Injury Prevention and Control (NCIPC) within the Centers for Disease Control and Prevention recently created a causal map that encapsulates ACEs and adolescent suicide in 361 concept nodes and 946 directed relationships. In this study, we examine this map and three similar models through three related questions: (Q1) how do existing network-based models of suicide differ in terms of node- and network-level characteristics? (Q2) Using the NCIPC model as a unifying framework, how do current suicide intervention strategies align with prevailing theories of suicide? (Q3) How can the use of network science on the NCIPC model guide suicide interventions?

In Tanzania, there are high rates of suicidal thoughts and behavior among people living with HIV (PLWH), yet few instruments exist for effective screening and referral. To address this gap, we developed and validated Swahili translations of the Columbia Suicide Severity Rating Scale (C-SSRS) Screen Version and two accompanying scales assessing self-efficacy to avoid suicidal action and reasons for living. We administered a structured survey to 80 PLWH attending two HIV clinics in Moshi, Tanzania. Factor analysis of the items revealed four subscales: suicide intensity, self-efficacy to avoid suicide, fear and social concern about suicide, and family and spirituality deterrents to suicide. The area under the receiver operating curve showed only suicide intensity, and fear and social concern met the prespecified cutoff of ≥0.7 in accurately identifying patients with a plan and intent to act on suicidal thoughts. This study provides early evidence that brief screening of intensity of suicidality in the past month, assessed by the C-SSRS Screen Version, is a strong, resource-efficient strategy for identifying suicide risk in the Tanzanian setting. Patients who report little fear of dying and low concern about social perceptions of suicide may also be at increased risk.

We previously showed that folic acid prescriptions for any indication were associated with lower rates of suicidal behaviour. Given that future randomised clinical trials are likely to focus on psychiatric disorders carrying elevated risk for suicide, we now report on the moderating effects of prior suicidal behaviour, psychiatric diagnoses and psychotropic medications on potential antisuicidal effects of folic acid. Data were obtained from the MarketScan Commercial Claims and Encounters databases that cover 164 million insured persons from 2005–2017, from which a cohort of 866 586 patients was derived. Analysis revealed no significant moderation effects on the antisuicidal effect of folic acid. These findings indicate that the potential benefit of folic acid for preventing suicidal behaviour is comparable in psychiatric populations at higher risk of suicide and that it may be additive to any benefit from psychotropic medications.

Given the high prevalence rate of suicidal ideation amongst medical students, medical lecturers and specialists as gatekeepers should be well-trained in suicide prevention. There is a need for validated measures to assess gatekeeper training gains for suicide prevention. The psychometric properties of the Advanced C.A.R.E. Suicide Prevention Gatekeeper Training Questionnaire (AdCARE-Q) were evaluated for a sample of medical lecturers and specialists in Malaysia. A total of 120 participants completed 24 items in the AdCARE-Q. Analysis of variance of perceived knowledge scores was performed. Exploratory factor analysis (EFA) was conducted. Reliability was calculated. The AdCARE-Q was reduced to 15 items that fit into two factors, “self-efficacy” and “declarative knowledge.” Overall internal consistency was good with Cronbach’s alpha = 0.84. The intraclass correlation coefficient between groups from the psychiatry department and non-psychiatry departments was good at 0.80. The oldest age group and participants from the Psychiatry department scored significantly higher than other groups in perceived knowledge of suicide prevention. This study found that the AdCARE-Q has adequate psychometric properties to assess suicide prevention gatekeeper training gains amongst medical lecturers and specialists. Confirmatory factor analysis is recommended for future studies.
