An integrative path model is presented that details the relationships among several demographic variables, life stress, depression, hopelessness, social support, and suicidal ideation. The sample consisted of 737 university students, 287 males and 450 females. Negative life stress was found to be a significant predictor of both depression and hopelessness, which, in turn, mediated the relationship between life stress and suicidal ideation. Contrary to previous findings, depression proved to be a better predictor of suicidal ideation than hopelessness. Findings also illustrated the importance of including social support measures in the model, as significant relationships were discovered between social support and both life stress and suicidal ideation. The model accounted for a total of 34% of the variance in suicidal ideation. Individual findings are interpreted; the ways in which they reflect on previous research, and future efforts, are discussed.
提出了一个综合路径模型，该模型详细阐述了几个人口统计学变量、生活压力、抑郁、绝望感、社会支持和自杀意念之间的关系。样本由737名大学生组成，其中287名男性和450名女性。研究发现负面生活压力是抑郁和绝望感的重要预测因素，而抑郁和绝望感反过来又介导了生活压力与自杀意念之间的关系。与之前的研究结果相反，抑郁被证明比绝望感更能预测自杀意念。研究结果还表明了在模型中纳入社会支持措施的重要性，因为发现社会支持与生活压力和自杀意念之间存在显著关系。该模型解释了自杀意念中34%的方差。对个体研究结果进行了解释，并讨论了它们对先前研究的反映方式以及未来的研究方向。
