The purpose of the present study was to relate suicidal intent to the suicide method chosen and the medical lethality of the suicidal act, and to discuss how ingestion of alcohol impacts these three factors. The study was based upon interviews with 139 suicidal patients admitted to the Department of Psychiatry of Odense University Hospital. The results indicated a tendency for suicide attempters using wrist-cutting to score low on the Suicidal Intent Scale. Patients using kinds of self-injury other than self-poisoning or wrist-cutting scored high. In the case of self-poisoning, suicidal intent did not influence the choice of toxic agent, nor was the choice of method and/or choice of toxic agent affected by alcohol ingestion. A correlation between suicidal intent and the lethality of the suicide attempt was seen only among patients without a diagnosis of alcohol dependence. Alcohol-dependent patients who made highly lethal attempts scored relatively low on the Suicidal Intent Scale. The results indicate that the lethality of the suicidal act is only an incomplete guide to a patient's suicidal intent. However, it should be stressed that, despite the fact that alcohol-dependent suicide attempters may not strongly wish to die, they are nonetheless at high risk for making fatal suicide attempts.
本研究的目的是将自杀意图与所选择的自杀方法及自杀行为的医学致死性联系起来，并探讨饮酒如何影响这三个因素。该研究基于对奥登塞大学医院精神病科收治的139名自杀患者的访谈。结果表明，采用割腕方式自杀的未遂者在自杀意图量表上得分较低。采用除中毒或割腕以外其他自我伤害方式的患者得分较高。在中毒案例中，自杀意图不影响毒物的选择，饮酒也不影响方法的选择和/或毒物的选择。仅在未诊断为酒精依赖的患者中，观察到自杀意图与自杀未遂致死性之间存在相关性。进行高度致命性自杀未遂的酒精依赖患者在自杀意图量表上得分相对较低。结果表明，自杀行为的致死性只是判断患者自杀意图的一个不完整指标。然而，应该强调的是，尽管酒精依赖的自杀未遂者可能并非强烈求死，但他们进行致命自杀未遂的风险仍然很高。
