We attempted to disentangle the interrelations between hopelessness, loneliness, and suicidal ideation, by comparing two conceptually driven models of their relationships, prospectively among 234 undergraduates, using a series of multiple regression/correlation equations. Model 1 framed loneliness as a risk factor for future suicidality that operates via its influence on hopelessness (the mediational view). Model 2 viewed hopelessness as a source variable that is predictive of both loneliness and suicidality, and postulated no relation between loneliness and suicidality beyond hopelessness. Model 2 received support, whereas Model 1 did not. We discuss the implications of our findings for the nomological status of hopelessness and loneliness as correlates of suicidality, and for exploration of the structural interrelations of suicide-related variables in general.
我们试图通过比较两种概念驱动的关系模型，对234名本科生进行前瞻性研究，使用一系列多元回归/相关方程，来理清绝望、孤独和自杀意念之间的相互关系。模型1将孤独视为未来自杀倾向的一个风险因素，它通过对绝望的影响起作用（中介观点）。模型2将绝望视为一个源变量，它可预测孤独和自杀倾向，并假定除绝望之外，孤独与自杀倾向之间不存在关联。模型2得到了支持，而模型1没有。我们讨论了研究结果对于绝望和孤独作为自杀相关因素的理论地位的影响，以及对于一般自杀相关变量结构相互关系探索的影响。
