Myths and Facts about Suicide from Individuals Involved in Suicide Prevention

Myth‐busting, in which a so‐called myth is presented and dispelled by facts, is used in suicide prevention gatekeeper trainings such as QPR. Evidence from other areas of public health shows this technique leads to memory for myths and not facts. An internet survey was used to determine if the “myths” and “facts” presented in QPR are endorsed as such by the suicidology community and to determine if demographics influenced statement identification. Overall, statements did reflect the opinions of the suicidology community and any type of training increased correct identification. Future research should focus on whether myth‐busting is an appropriate strategy for suicidology.     

Assessing the Adherence to Guidelines of Media Reporting of Suicide Using a Novel Instrument—the “Risk of Imitative Suicide Scale” (RISc)

Media guidelines for reporting of suicide are considered important in suicide prevention because of the risk of “imitative” suicide. There are currently no established tools for the quantification of quality of reporting. We sought to develop and validate a quality assessment instrument—the Risk of Imitative Suicide Scale (RISc). The RISc appears capable of discriminating reliably between adherent and nonadherent articles. Our data suggest that adherence to guidelines is inconsistent, and there are major differences between web‐based and print media. The RISc could be used to evaluate effectiveness and consistency of media engagement with suicide prevention strategies.     

Relations among Behavioral and Questionnaire Measures of Impulsivity in a Sample of Suicide Attempters

Despite the focus on impulsivity within suicide research, it remains unclear the extent to which impulsivity assessments, that purportedly tap similar constructs, show significant overlap in samples of individuals with suicidal behaviors. In a sample of 69 suicide attempters, we took a multitrait, multimethod approach to examine the relation among various questionnaire and behavioral assessments of impulsivity facets. With the exception of urgency and go–stop performance, there was little evidence of concordance between questionnaire and behavioral measures. These findings suggest researchers cannot presume that measures of “impulsivity” assess similar psychological processes and that more nuanced terminology is needed.     

Using the Suicide Index Score to Predict Treatment Outcomes among Psychiatric Inpatients

For many suicidal people, the desire to die is moderated by a competing desire to live. This study aimed to demonstrate the ability of a wish‐to‐live versus wish‐to‐die index score to measure ambivalence and trichotomize suicidal inpatients into distinct stratified risk groups. Analyses revealed that index scores calculated for patients at treatment start significantly discriminated among the groups at index and uniquely predicted suicidal ideation, hopelessness, and depression scores across treatment. On average, patients with wish‐to‐live and wish‐to‐die orientations resolved suicidal ideation by discharge. Changes in suicidal ideation among ambivalently oriented patients were more variable. Clinical and research implications are discussed.
