Background: Suicidality is a major global health problem and the second leading reason of mortality in 15-29-year-olds, and a growing subgroup of these youths are students. The Present study aimed at evaluating the psychometric properties of the Persian version of SIDAS among the Iranian college students.Method: A total of 398 Iranian college students completed study measures online.We chose the Beck scale for suicide ideation, Beck hopelessness scale, and Connor and Davidson Resilience Scale for evaluating the concurrent and divergent validities. The CVI index was calculated in order to check the face validity and content validity. Confirmatory factor analysis was performed to confirm the factors of the SIDAS. Finally, ROC curves were constructed to assess scale sensitivity and specificity.Results: According to the findings, the 286 (71.9%) of participants were women.The average age of the sample was 23.9 years old. According to this study, the SIDAS-P demonstrated high internal consistency (a =0 .799), a unifactorial structure, a moderate correlation with BSSI, and a negative moderate divergent validity with Connor and Davidson resilience scale. Furthermore, the ROC curve analysis (AUC = 0.909) indicated that the SIDAS-P could distinguish individuals with a high risk for suicidal behaviors (scores higher than 6.5 on the SIDAS are above the low risk for suicide).The findings support that the SIDAS is a valid and reliable online instrument for screening suicidal ideations in a population of nonclinical college students in Iran. To establish its clinical utility, further research should test its psychometric properties in clinical population with different mental health problems.
