目的：到目前为止，大多数研究人员依赖于自杀项目的规模主要是为了衡量抑郁症的严重程度，以捕捉自杀意念（SI）。本研究旨在调查临床医生评定的汉密尔顿抑郁量表（HAM-D）自杀项目及其主要因素与贝克抑郁量表（SSI）的SI评分之间的相关性。方法：对2007 ~ 2009年连续住院的281例自杀未遂者进行了SSI、HAM-D和Beck抑郁自评量表（BDI）的评定。主成分分析（PCA）计算提取主要因素。结果：主成分分析得出三个分量，即自杀因子、自杀因子和自杀因子。因子2显示HAM-D自杀项目的主要负荷。HAM-D自杀项目和因子2均与SSI总分呈正相关（均p
Objective: To date, most researchers rely on suicidal items of scales primarily designed to measure depression severity to capture suicidal ideation (SI). This study aims at investigating how well the suicide item of the clinician rated Hamilton Scale for Depression (HAM-D) and principal factors derived from this scale correlate with SI scores derived from a well validated measure of SI: the Beck's scale for SI (SSI).Method: 281 suicide attempters consecutively hospitalized between 2007 and 2009 were assessed by using the SSI, the HAM-D and the self-report Beck Depression Inventory (BDI). Principal Component Analysis (PCA) was computed to extract main factors. Correlations between these factors, BDI's and HAM-D's suicide items and the SSI scores were then computed.Results: Three components were derived from the PCA. Factor 2 showed a major loading for the HAM-D suicide item. Both the HAM-D suicide item and Factor 2 positively correlated with the SSI total score (both p
