This study aimed to Sinicize the Literacy of Suicide Scale (LOSS) and to test the reliability and validity of the LOSS with Chinese nurses.
After authorization was obtained from the original author, the LOSS was translated into Chinese and translated back into English in accordance with Brislin's translation principle. Eight experts were invited to evaluate the scale's content validity, and the Chinese version of the LOSS was obtained. Moreover, the LOSS was used to assess the suicide literacy of 1,000 nurses from Beijing, Hubei, Henan, and Sichuan Provinces in China, and the reliability and validity of the scale were tested.
The Chinese version of the LOSS contains 26 items covering four dimensions: signs of suicide, risk factors for suicide, the cause/nature of suicide, and the treatment/prevention of suicide. Cronbach's coefficient for the LOSS was 0.933, and Cronbach's coefficients of the four dimensions were 0.832, 0.893, 0.898, and 0.827. The split-half reliability of the LOSS was 0.818, and the split-half reliabilities of the four dimensions were 0.835, 0.877, 0.890, and 0.819. The test-retest reliability of the LOSS was 0.925, and the test-retest reliabilities of the four dimensions were 0.890, 0.885, 0.892, and 0.904. The item-level content validity index (I-CVI) of the scale was 0.875-1.000, and the scale-level content validity index (S-CVI) was 0.947. Four common factors were extracted via exploratory factor analysis, and the cumulative variance contribution rate was 60.233%. The confirmatory factor analysis results show that the model had a good fit.
The Chinese version of the LOSS has good reliability and validity and is a suitable assessment tool for assessing nurses' suicide literacy in the Chinese cultural context.
本研究旨在将自杀素养量表（LOSS）汉化，并检验其在中国护士群体中的信效度。
经原作者授权，按照 Brislin 翻译原则将 LOSS 翻译成中文后再回译为英文。邀请 8 名专家对量表进行内容效度评估，得到 LOSS 中文版。此外，使用 LOSS 对来自中国北京、湖北、河南和四川四省的 1000 名护士的自杀素养进行评估，并检验量表的信效度。
LOSS 中文版包含 26 个条目，涵盖自杀迹象、自杀风险因素、自杀原因/本质以及自杀治疗/预防四个维度。LOSS 的 Cronbach's α系数为 0.933，四个维度的 Cronbach's α系数分别为 0.832、0.893、0.898 和 0.827。LOSS 的分半信度为 0.818，四个维度的分半信度分别为 0.835、0.877、0.890 和 0.819。LOSS 的重测信度为 0.925，四个维度的重测信度分别为 0.890、0.885、0.892 和 0.904。量表的条目水平内容效度指数（I-CVI）为 0.875 - 1.000；量表水平内容效度指数（S-CVI）为 0.947。探索性因子分析提取出四个公因子，累积方差贡献率为 60.233%。验证性因子分析结果显示模型拟合良好。
LOSS 中文版具有良好的信效度，是在中国文化背景下评估护士自杀素养的适宜测评工具。
