This study established the psychometric properties of the Chinese version of the Suicide Intent Scale (SIS) in a clinic- and community-based sample of 36 patients and 592 respondents, respectively. Results showed that the Chinese SIS demonstrated good inter-rater and test-retest reliability. Factor analysis generated three factors (Precautions, Planning, and Seriousness) explaining 92.9% of the total variance with high internal consistency. It was moderately correlated with depressive symptoms. Results suggest that the Chinese SIS is a reliable and valid instrument for use in assessing the extent of suicidal intention among subjects with deliberate self-harm in ethnic Chinese populations.
