A self-report version of the Scale for Suicide Ideation (SSI) was administered to 50 inpatients diagnosed with mixed DSM-III psychiatric disorders and 55 outpatients with affective disorders. The self-report SSI was written for both paper-and-pencil and computer administration. The correlations between the self-reported and clinically rated versions for both inpatients and outpatients were greater than .90, which suggests strong concurrent validity. The Cronbach coefficient alphas for the paper-and-pencil and computer versions were also in the .90s and indicated high internal consistency. Furthermore, the mean SSI scores of the computer version for both the inpatients and outpatients were higher than the mean SSI scores of the clinical ratings; the patients described more severe suicide ideation than clinicians reported.
一份自杀意念量表（SSI）的自陈式版本被施用于50名被诊断患有混合性DSM-III精神障碍的住院患者以及55名患有情感障碍的门诊患者。自陈式SSI专为纸笔作答和计算机施测而编写。住院患者和门诊患者的自陈式版本与临床评定版本之间的相关性均大于0.90，这表明具有很强的同时效度。纸笔作答版本和计算机版本的克朗巴赫系数α也都在0.90以上，表明具有较高的内部一致性。此外，住院患者和门诊患者计算机版本的SSI平均得分均高于临床评定的SSI平均得分；患者描述的自杀意念比临床医生报告的更为严重。
