Abstract:	Background/Purpose Early detection of suicide risk is a challenge in suicide prevention. A comprehensive yet efficient tool providing timely identification of key risk factors allows healthcare providers to initiate interventions. The study aims to validate the 9-item Concise Mental Health Checklist (CMHC-9). Methods A series of cross-sectional surveys were conducted in 3982 participants from psychiatric outpatient (n = 931), medical outpatient (n = 931) and community (n = 2120) populations. The factor analysis with internal consistency coefficients (Cronbach's α) and receiver operating characteristic (ROC) analysis were performed to evaluate the scale's reliability and validity. Results The internal consistency of the CMHC-9 was satisfactory based on Cronbach's α values for the total sample (α = 0.79) and the three sub-samples (i.e., α = 0.76 for psychiatric subjects; 0.67 for community subjects; and 0.69 for medical outpatient subjects). Hierarchical exploratory factor analysis revealed that the CMHC-9 was a single-dimensional scale with two-factor structure of psychopathology and suicidality. The two-factor solution was confirmed by confirmatory factor analysis. The optimal cut-off of 3/4 obtained from the ROC analysis represented a satisfactory sensitivity (92%) and specificity (82%) in identifying recent suicide ideation. Conclusion This large-scale study confirmed the CMHC-9 as a brief and effective tool for suicide risk detection. It is recommended that CMHC-9 can be used for care engagement and risk identification in both medical and community settings among people at risk for suicide.
