About this screener — evidence, source, alternatives

A brief self-report screen for the presence and severity of suicidal thoughts in community and online settings, developed at the Australian National University. Each item rates one attribute of suicidal ideation; anyone answering “Never” to the first item skips the rest and scores zero.

Evidence · validated

Validated in an online survey of community-based Australian adults (n = 1,352). A cut-off of 1 had sensitivity of 85.5% for suicide plans and 84.0% for attempts (specificity 67.1% and 63.6%). Scores ≥ 21 had 95.8% specificity for a suicide plan and 94.9% for preparation/attempt in the past year (sensitivity 39.6% and 50.0%). Cronbach’s alpha 0.91; convergent validity with the C-SSRS and PHQ-9 (van Spijker et al., 2014).
