Résumé

L’étude décrit l’élaboration et la validation psychométrique préliminaire de l’Échelle des attributs de l’idéation suicidaire modifiée (SIDAS-M), une évaluation en cinq items de l’idéation suicidaire destinée aux adultes autistes. Les participants (n = 102 adultes autistes ; 58 % de femmes, 34 % d’hommes, 8 % de personnes non binaires ; âge M = 41,75, ET = 12,89) ont rempli une enquête en ligne incluant la SIDAS-M au temps 1 et ont participé à des entretiens de suivi au temps 2 (environ 111 jours plus tard). Une solution à un seul facteur a fourni un ajustement bon à excellent aux données (indice d’ajustement comparatif = 0,961, indice de Tucker-Lewis = 0,921 ; résidu quadratique moyen standardisé = 0,027), tous les items présentant des saturations bonnes à excellentes (0,74–0,91). Le score total de la SIDAS-M (ω = 0,930, intervalle de confiance à 95 % corrigé du biais et accéléré [IC à 95 % BCa] [0,90, 0,95]) a démontré une bonne validité convergente, corrélant significativement avec les mesures existantes spécifiques au suicide (ρ = 0,442–0,698, p < 0,001) et de bien-être (ρ = 0,325–0,505, p ≤ 0,001), ainsi qu’une bonne validité divergente. Une régression logistique contrôlant l’âge, le genre et le statut relationnel a indiqué que les scores SIDAS-M au temps 1 prédisaient significativement le comportement suicidaire au temps 2, β = 0,462, p < 0,001, [0,032, 0,068]. L’analyse de la courbe des caractéristiques de fonctionnement du récepteur a indiqué que la SIDAS-M permettait de distinguer les participants classés comme présentant un risque faible ou supérieur à faible, aire sous la courbe = 0,866, [0,767, 0,966], p < 0,001, avec un score seuil ≥ 1 fournissant un indicateur potentiellement utile d’un risque suicidaire accru. Dans l’ensemble, la SIDAS-M a démontré de bonnes propriétés psychométriques lorsqu’elle est utilisée auprès d’adultes autistes sans déficience intellectuelle. Résumé grand public Les personnes autistes peuvent présenter un risque plus élevé de comportement suicidaire que les personnes de la population générale. Le comportement suicidaire peut inclure le fait de penser au suicide ou de tenter de mettre fin à sa propre vie par suicide. Il est important d’identifier les personnes autistes qui peuvent penser au suicide. Les personnes présentant un risque de comportement suicidaire peuvent être identifiées en leur posant des questions sur le fait qu’elles ont pensé au suicide. Un questionnaire spécialement conçu, ou instrument de dépistage, peut aider quelqu’un à poser les meilleures questions afin de déterminer si une personne a pensé au suicide. Ces informations peuvent aider à identifier les soutiens à mettre en place pour prévenir le comportement suicidaire, tel qu’une tentative de suicide. Cependant, les personnes autistes peuvent interpréter les questions différemment des personnes non autistes. Il est important d’utiliser des outils de dépistage qui ont été conçus avec et pour les personnes autistes. Dans cette étude, nous avons examiné l’Échelle des attributs de l’idéation suicidaire (SIDAS). La SIDAS est un outil existant qui a été élaboré pour dépister les pensées suicidaires dans la population générale. Nous avons modifié la SIDAS pour l’utiliser auprès d’adultes autistes. Nous avons impliqué des personnes autistes dans le processus de modification de la SIDAS. Nous avons appelé l’instrument modifié la SIDAS-M. Les résultats de notre étude ont montré que la SIDAS-M pourrait être utile pour le dépistage des pensées suicidaires chez les adultes autistes qui ne présentent pas de déficience intellectuelle.

The study describes the development and preliminary psychometric validation of the Suicidal Ideation Attributes Scale-Modified (SIDAS-M), a five-item assessment of suicidal ideation for use with autistic adults. Participants (n = 102 autistic adults; 58% women, 34% men, 8% nonbinary; M age = 41.75, SD = 12.89) completed an online survey including the SIDAS-M at Time 1 and participated in follow-up interviews at Time 2 (~111 days later). A single factor solution provided good to excellent fit to the data (comparative fit index = 0.961, Tucker–Lewis index = 0.921; standardized root mean square residual = 0.027), with all items showing good to excellent loadings (0.74–0.91). SIDAS-M total score (ω=.930, bias-corrected and accelerated 95% confidence interval (BCa 95% CI) [.90,.95]) demonstrated good convergent validity, correlating significantly with existing suicide specific (ρ=.442–.698, p<.001) and well-being measures (ρ=.325.–.505, p≤.001), and good divergent validity. Logistic regression controlling for age, gender, and relationship status indicated that SIDAS-M scores at Time 1 significantly predicted suicidal behavior at Time 2, β = 0.462, p < 0.001, [0.032, 0.068]. Receiver operating characteristic curve analysis indicated SIDAS-M has utility discriminating between participants classified at low or above low risk, area under the curve = 0.866, [0.767, 0.966], p < 0.001, with a cutoff score ⩾1 providing a potentially useful indicator of increased suicidal risk. Overall, SIDAS-M demonstrated good psychometric properties when used with autistic adults without intellectual disability. Lay Abstract Autistic people may be at higher risk of suicidal behavior than people in the general population. Suicidal behavior may include thinking about suicide or attempting to end one’s own life by suicide. It is important to identify autistic people who may be thinking about suicide. People who are at risk of suicidal behavior can be identified by asking questions about whether they have been thinking about suicide. A specially designed questionnaire, or screening instrument, can help someone ask the best questions to find out if someone has been thinking about suicide. This information can help to identify supports to be put in place to prevent suicidal behavior, such as a suicide attempt. However, autistic people may interpret questions differently than non-autistic people. It is important to use screening tools that have been designed with, and for autistic people. In this study, we examined the Suicidal Ideation Attributes Scale (SIDAS). The SIDAS is an existing tool that was developed to screen for suicidal thinking in the general population. We modified SIDAS for use with autistic adults. We involved autistic people in the process of modifying SIDAS. We called the modified instrument the SIDAS-M. The results of our study showed SIDAS-M may be useful for screening for suicidal thinking in autistic adults who do not have an intellectual disability.
