Abstract
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; Mage = 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 ..
