BACKGROUND: Die by suicide is a significant public health issue globally, especially among individuals with mental health diagnoses. An efficient and reliable tool for suicidal intervention is urgently needed to identify those who are in danger. A widely recognized tool for assessing the risk of death by suicide around the world is the Columbia-Suicide Severity Rating Scale (C-SSRS). This study conducted an assessment of the C-SSRS's psychometric qualities among participants with mental health diagnoses in China. METHODS: Of the 614 individuals diagnosed with mental health diagnoses who participated in the study, 161 had previously attempted to take their own life. Reliability was assessed using Cronbach's alpha and McDonald's omega. The construct validity was tested using ULSMV (unweighted least squares with mean- and variance-adjusted standard errors). Discriminant and convergent validity were evaluated using the third item of the Hamilton Depression Rating Scale (HAMD-17) and the Schizophrenia Quality of Life Scale (SQLS). Participants' history of suicide attempts was used to calculate predictive validity. RESULTS: The analysis demonstrated that the C-SSRS exhibited satisfactory internal consistency. The Cronbach alpha was 0.869, and McDonald's omega was 0.871. The C-SSRS's three-factor structure and the two-component structure of the suicidal ideation intensity subscale were both validated by confirmatory factor analysis (CFA). Data analysis revealed that the active-passi...
