Using a military sample comprised largely of National Guard personnel, zero-inflation negative binomial regression was applied to estimate the effects of indirect, nonface valid indicators of suicide ideation [Thwarted Belongingness (TB), Perceived Burdensomeness (PB), and Hopelessness], in predicting suicide ideation. Data from a sample of 497 military personnel (82.1% male; m = 27.24; range = 18-59) were analyzed. TB and the interaction of TB with Hopelessness were significant predictors in the logistic regression, and in the negative binomial regression, the main effects of TB and hopelessness, and the interactions of TB with hopelessness and PB with hopelessness were significant. The findings further indicated that approximately 10% of those not reporting ideation would be predicted to be ideators. Clinically, these results indicate that, in samples reluctant to report ideation, the assessment of suicide risk may improve through the use of relevant measures that do not explicitly reference suicide thoughts.
采用一个主要由国民警卫队人员组成的军事样本，零膨胀负二项回归被应用于估计间接的、非有效的自杀意念指标（归属感受挫、被感知的累赘和无望感）对自杀意念的预测作用。对 497 名军事人员（82.1%男性；m=27.24；范围=18-59）的样本数据进行了分析。归属感受挫和归属感受挫与无望感的交互作用在逻辑回归中是显著的预测因子，而在负二项回归中，归属感受挫和无望感的主效应，以及归属感受挫与无望感和无望感与被感知的累赘的交互作用都是显著的。研究结果进一步表明，大约 10%没有报告意念的人被预测为意念者。临床上，这些结果表明，在那些不愿意报告意念的样本中，通过使用不明确提及自杀想法的相关措施来评估自杀风险可能会得到改善。
