探讨了自杀意念-当前量表(SSI-C；Beck，Kovacs&Weissman，1979，《咨询与临床心理学杂志》，47,343-352)和自杀意念-最差量表(SSI-W；Beck，Brown，Steer，Dahlsgaard&Grisham，1997)的心理测量学特性。这些由临床医生管理的19项量表测量了目前的自杀意念(SSI-C)以及患者一生中最糟糕的自杀意念(SSI-W)。在4063名门诊患者的样本中，这两个量表都与主要情绪障碍的诊断、人格障碍的诊断以及抑郁和绝望的衡量标准呈正相关。社会支持指数与自杀未遂史之间的关系(r=0.5，P<；0.001)强于社会支持量表与既往自杀未遂之间的关系(r=0.31，P<；0.001)。对于444个当前自杀意念者和1764个过去自杀意念者，SSI-C和SSI-W具有较高的内部一致性(系数αS分别为0.84和0.89)。SSI-C与SSI-W呈中等相关(r=0.51P<；0.001)。迭代的最大似然主因素分析确定了两个量表背后的可比准备和动机维度。(C)1997年爱思唯尔科学有限公司。
The psychometric properties of the Scale for Suicide Ideation-Current (SSI-C; Beck, Kovacs & Weissman, 1979, Journal of Consulting and Clinical Psychology, 47, 343-352) and the Scale for Suicide Ideation-Worst (SSI-W; Beck, Brown, Steer, Dahlsgaard & Grisham, 1997, in press) were explored. These 19-item clinician-administered scales measure current suicide ideation (SSI-C) as well as suicide ideation at its worst point in the patient's life (SSI-W). For a sample of 4063 outpatients, both scales were positively correlated with a diagnosis of a principal mood disorder, a diagnosis of a personality disorder, and measures of depression and hopelessness. The relationship between the SSI-W and a history of suicide attempts was stronger (r = 0.50, P < 0.001) than the relationship between the SSI-C and previous suicide attempts (r = 0.31, P < 0.001). For 444 current and 1764 past suicide ideators, the SSI-C and the SSI-W had high internal consistencies (coefficient alpha s = 0.84 and 0.89, respectively). The SSI-C and the SSI-W were moderatedly correlated with each other (r = 0.51, P < 0.001). Iterated maximum-likelihood principal-factor analyses identified comparable Preparation and Motivation dimensions underlying both scales. (C) 1997 Elsevier Science Ltd.
