Research on the factor structures of the Scale for Suicidal Ideation (SSI; [Beck, A.T., Kovacs, M., Weissman, M., 1979. Assessment of suicidal intention: the Scale for Suicide Ideation. J. Consult. Clin. Psychol. 47, 343-352]) and the Modified Scale for Suicide Ideation (MSSI; [Miller, I.W., Norman. W.H., Bishop, S.B., and Dow, M.G., 1986. The modified scale for suicidal ideation: reliability and validity. J Consult Clin Psychol, 54, 724-725]) in younger adults have tended to yield two factor solutions. The purpose of the current study was to examine the factor structure of the SSI in an older population in order to determine whether the factor structure was similar and, if so, whether the factors related to other clinical and demographic correlates.
199 participants (M age 57, S.D.) were selected from a combined database of psychiatric outpatients and inpatients over the age of 49 currently experiencing suicidal ideation. Principal axis factoring was used in order to determine the factor structure of the SSI. In addition, we ran correlations and regression analyses to determine the relation of each factor with other clinical and demographic correlates.
Consistent with prediction, we found a two-factor solution. Also consistent with predictions, clinical and demographic correlates related differentially to each of the factors.
The relatively small sample size and the fact that our sample was predominantly Caucasian.
The current study has provided data on the factor structure of the SSI in an older population, demonstrating that suicidal ideation in this group is similar to younger age groups.
关于自杀意念量表（SSI；[贝克，A.T.，科瓦奇，M.，魏斯曼，M.，1979年。自杀意图评估：自杀意念量表。《咨询与临床心理学杂志》47，343 - 352]）和改良自杀意念量表（MSSI；[米勒，I.W.，诺曼，W.H.，毕晓普，S.B.，和道，M.G.，1986年。改良自杀意念量表：信度和效度。《咨询与临床心理学杂志》54，724 - 725]）在年轻成年人中的因素结构研究倾向于得出两因素解决方案。本研究的目的是检验老年人群中SSI的因素结构，以确定因素结构是否相似，如果相似，这些因素是否与其他临床和人口统计学相关因素有关。
从年龄在49岁以上目前有自杀意念的精神科门诊患者和住院患者的综合数据库中选取了199名参与者（平均年龄57岁，标准差）。使用主轴因子分析来确定SSI的因素结构。此外，我们进行了相关性和回归分析，以确定每个因素与其他临床和人口统计学相关因素的关系。
与预测一致，我们发现了一个两因素解决方案。同样与预测一致的是，临床和人口统计学相关因素与每个因素的关系不同。
样本量相对较小，且我们的样本主要是白种人。
本研究提供了老年人群中SSI因素结构的数据，表明该组的自杀意念与年轻年龄组相似。
