Abstract

<p xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" class="first" dir="auto" id="d5475700e91">Adolescence is a period of elevated risk for suicide, and mental health professionals expressed concerns that suicidal behaviours and suicide rates may increase among this age group during the COVID-19 pandemic. Adolescent suicide rates, attempts, and ideation during the pandemic varied depending on the country, data collection methodology, and population (e.g., general population vs. emergency department). Many pre-pandemic risk factors for suicidal behaviour or ideation were identified as risk factors during the pandemic; however, there was also some evidence that certain groups were disproportionately at risk, such as girls, and adolescents identifying as Black, Asian, American Indian/Alaska Native, or Asian/Pacific Islander. Given the trend of increased adolescent suicide in many countries over the past two decades, there is an ongoing need to direct resources toward prevention programs, screening, and evidence-based interventions for suicide risk. </p>

The Columbia-Suicide Severity Rating Scale: initial validity and internal consistency findings from three multisite studies with adolescents and adults.

Kelly Posner, Gregory Brown, Barbara Stanley … (2011)

Research on suicide prevention and interventions requires a standard method for assessing both suicidal ideation and behavior to identify those at risk and to track treatment response. The Columbia-Suicide Severity Rating Scale (C-SSRS) was designed to quantify the severity of suicidal ideation and behavior. The authors examined the psychometric properties of the scale. The C-SSRS's validity relative to other measures of suicidal ideation and behavior and the internal consistency of its intensity of ideation subscale were analyzed in three multisite studies: a treatment study of adolescent suicide attempters (N=124); a medication efficacy trial with depressed adolescents (N=312); and a study of adults presenting to an emergency department for psychiatric reasons (N=237). The C-SSRS demonstrated good convergent and divergent validity with other multi-informant suicidal ideation and behavior scales and had high sensitivity and specificity for suicidal behavior classifications compared with another behavior scale and an independent suicide evaluation board. Both the ideation and behavior subscales were sensitive to change over time. The intensity of ideation subscale demonstrated moderate to strong internal consistency. In the adolescent suicide attempters study, worst-point lifetime suicidal ideation on the C-SSRS predicted suicide attempts during the study, whereas the Scale for Suicide Ideation did not. Participants with the two highest levels of ideation severity (intent or intent with plan) at baseline had higher odds for attempting suicide during the study. These findings suggest that the C-SSRS is suitable for assessment of suicidal ideation and behavior in clinical and research settings.

Suicide, Suicide Attempts, and Suicidal Ideation

E Klonsky, Alexis May, Boaz Y. Saffer (2016)

Suicidal behavior is a leading cause of death and disability worldwide. Fortunately, recent developments in suicide theory and research promise to meaningfully advance knowledge and prevention. One key development is the ideation-to-action framework, which stipulates that (a) the development of suicidal ideation and (b) the progression from ideation to suicide attempts are distinct phenomena with distinct explanations and predictors. A second key development is a growing body of research distinguishing factors that predict ideation from those that predict suicide attempts. For example, it is becoming clear that depression, hopelessness, most mental disorders, and even impulsivity predict ideation, but these factors struggle to distinguish those who have attempted suicide from those who have only considered suicide. Means restriction is also emerging as a highly effective way to block progression from ideation to attempt. A third key development is the proliferation of theories of suicide that are positioned within the ideation-to-action framework. These include the interpersonal theory, the integrated motivational-volitional model, and the three-step theory. These perspectives can and should inform the next generation of suicide research and prevention.
