In the present study, we examined loneliness and negative life events as predictors of suicide risk (viz., hopelessness and suicidal behaviors) in a sample of 160 Hispanic adults. Consistent with expectations, we found loneliness and negative life events to be positively associated with both hopelessness and suicidal behaviors. In addition, results of conducting hierarchical regression analyses indicated that loneliness accounted for significant amounts of variance in both measures of suicide risk, ranging from 24% to 29% of the variance. The inclusion of negative life events as a predictor was found to account for additional unique variance in hopelessness (3%), but not in suicidal behaviors, beyond what was predicted by loneliness. Finally, consistent with a diathesis-stress model, the Loneliness × Negative Life Events interaction was found to account for an additional 3% of the variance in both suicide risk measures. Implications of the present findings for future research on suicide risk in Hispanics are discussed.
在本研究中，我们考察了孤独感和负性生活事件对自杀风险（即绝望和自杀行为）的预测作用，研究对象为 160 名西班牙裔成年人。与预期一致，我们发现孤独感和负性生活事件与绝望和自杀行为均呈正相关。此外，进行分层回归分析的结果表明，孤独感可解释自杀风险两个指标中相当大比例的变异，范围在 24%至 29%之间。将负性生活事件作为预测因素，发现其可在孤独感之外，进一步解释绝望感（3%）方面的独特变异，但无法解释自杀行为方面的变异。最后，与素质-应激模型一致，孤独感×负性生活事件的交互作用可解释自杀风险两个指标中另外 3%的变异。本研究结果对未来西班牙裔人群自杀风险研究具有启示意义。
