This study, built on Jacobs' conceptual work, considered the interaction of a complex of predictor variables (hopelessness; locus of control; preference for inclusion, control, and affection; and stress from life events) in relation to the degree of suicide intent. Although the multiple regression equation computed for the combination of variables was significantly related to the criterion variable, suicide intent, hopelessness and preference for affection were the only major variables that contributed a significant amount of variance. Hopelessness, however, was the only variable that significantly related to suicide intent when considered outside the context of the multiple regression equation. In addition, the correlations between locus of control and hopelessness, as well as preference for affection and hopelessness, were significant and appeared to account for different variance than accounted for by the correlation of hopelessness and suicide intent.
本研究基于雅各布斯的概念性工作，考察了一系列预测变量（绝望感、控制点、对接纳、控制和情感的偏好以及生活事件带来的压力）之间的相互作用与自杀意图程度的关系。尽管为这些变量组合计算出的多元回归方程与标准变量自杀意图显著相关，但绝望感和对情感的偏好是仅有的两个能解释大量方差的主要变量。然而，当在多元回归方程的背景之外考虑时，绝望感是唯一与自杀意图显著相关的变量。此外，控制点与绝望感之间的相关性，以及对情感的偏好与绝望感之间的相关性都很显著，而且它们似乎解释了与绝望感和自杀意图相关性所解释的方差不同的方差。
