The aims of this study were to evaluate and compare the performance of the Chinese version of the Suicide Ideation Scale-Current (SSI-C) and the Suicide Ideation Scale-Worst (SSI-W) as suicide ideation screening tools in patients with epilepsy (PWE).
A consecutive sample of Chinese adult PWE recruited from a tertiary hospital completed the SSI-C and SSI-W and the suicidality module of the Chinese version of the Mini International Neuropsychiatric Interview (MINI) Plus 5.0.0.
A total of 260 consecutive PWE were recruited. The area under the curve (AUC) for the SSI-C was 0.831, and the optimal cutoff score was >1 (sensitivity 73%, specificity 91%); for the SSI-W, the AUC was 0.958, and the optimal cutoff score was >2 (sensitivity 94.6%, specificity 87.4%). The AUC for the SSI-W was larger than that for the SSI-C, and the two-factor structure was considered significant.
Our results showed that the SSI-C and SSI-W had good validity as suicidal ideation screening tools in PWE in southern China and can be recommended for clinical suicidal ideation screening. The SSI-W is a better suicidal ideation screening tool than the SSI-C according to the results of our study.
本研究旨在评估和比较中文版自杀意念量表-当前（SSI-C）和中文版自杀意念量表-最差（SSI-W）作为癫痫患者（PWE）自杀意念筛查工具的性能。
连续纳入一家三级医院的中国成年 PWE 患者，完成 SSI-C 和 SSI-W 以及中文版 Mini 国际神经精神访谈（MINI）Plus 5.0.0 的自杀模块。
共纳入 260 例连续 PWE。SSI-C 的曲线下面积（AUC）为 0.831，最佳截断值>1（灵敏度 73%，特异性 91%）；对于 SSI-W，AUC 为 0.958，最佳截断值>2（灵敏度 94.6%，特异性 87.4%）。SSI-W 的 AUC 大于 SSI-C，且两因素结构具有显著意义。
我们的结果表明，SSI-C 和 SSI-W 在中国南方的 PWE 中作为自杀意念筛查工具具有良好的有效性，可推荐用于临床自杀意念筛查。根据我们的研究结果，SSI-W 是一种比 SSI-C 更好的自杀意念筛查工具。
