Psychometric validation of the French version of the Suicidal Ideation Attributes Scale (SIDAS-FR)

Abstract

The purpose of this study was to validate in French the Suicidal Ideation Attributes Scale (SIDAS) using an online community survey that was completed by 2304 French-speaking Quebec participants (adolescents and adults). The SIDAS-FR demonstrated high internal consistency (α = .83), a unifactorial structure, and strong convergent validity with relevant constructs. Cutoff scores of ≥13 for moderate severity and ≥20 for high severity of suicidal ideations were optimal. The excellent psychometric properties of the French-Canadian version of the SIDAS support its use as an effective tool for online screening of suicidal ideations, for both adolescents and adults.
