Predictive Validity and Cutoff Scores of the Revised Suicide Crisis Inventory in Korean Adults: A One-Year Follow-Up Study

Year: 2025

Type: article

Abstract: OBJECTIVE: This study aimed to examine the predictive validity of the revised Suicide Crisis Inventory (SCI-2) and determine its optimal cutoff score. METHODS: Data from 662 community adults participating in a one-year follow-up study were analyzed. Receiver operating characteristic analysis was conducted to examine whether the SCI-2 could predict suicide attempts and ideation with intent at the follow-up and to determine the optimal cutoff score for identifying individuals at high risk for suicide. RESULTS: The SCI-2 demonstrated adequate predictive validity for suicide attempts and ideation with intent at the one-year follow-up. Based on Youden's index and Runeson et al.'s criteria, a cutoff score of 102 was proposed as the threshold for high-risk groups. CONCLUSION: The SCI-2, a measure of Suicide Crisis Syndrome, demonstrated predictive validity using longitudinal data. It is effective in identifying high-risk individuals in a community population. These findings highlight the SCI-2 as a valuable tool for early suicide risk detection and prevention.
