The authors evaluated a structural model of the relationship between cognitive functioning and geriatric suicide ideation, mediated by Depression/Hopelessness, a latent construct characterized by a combination of the two. A heterogeneous sample of 90 elderly participants completed the Geriatric Suicide Ideation Scale, a new, multidimensional self-report measure of suicide ideation in seniors, and measures of cognitive functioning, depression, and both global and social forms of hopelessness. The results demonstrated significant associations between suicide ideation and the various predictor variables. The results of structural-equation modeling supported the proposed mediational model, indicating that the Depression/Hopelessness construct mediates the relationship between cognitive functioning and suicide ideation among older persons. These findings have implications for the conceptualization and treatment of potentially suicidal elderly persons.
作者评估了认知功能与老年自杀意念之间关系的结构模型，该模型以抑郁/绝望为中介，抑郁/绝望是一个由两者结合而成的潜在结构。90名老年参与者组成的异质性样本完成了老年自杀意念量表（一种针对老年人自杀意念的新的多维自我报告测量工具）以及认知功能、抑郁、总体绝望和社交绝望方面的测量。结果表明自杀意念与各种预测变量之间存在显著关联。结构方程模型的结果支持了所提出的中介模型，表明抑郁/绝望结构在老年人认知功能与自杀意念之间起中介作用。这些发现对潜在自杀老年人的概念化和治疗具有启示意义。
