Background: Suicidal intent for patients attempting suicide using violent methods (VMs) is assumed to be higher than for those using self-poisoning (SP), which may explain the higher mortality observed in follow-up studies. However, this has not been studied prospectively. Aims: We aimed to compare patients attempting suicide using VMs with those using SP regarding suicidal intent, suicidal ideation, depression, and hopelessness during hospital stay and after 1 year. Methods: Patients hospitalized after suicide attempt by VMs (n = 80) or SP (n = 81) completed the Beck scales for Suicide Intent, Suicide Ideation, Depression Inventory, and Hopelessness on admission and at the 12-month follow-up. Results: On admission, those using VMs had higher suicidal intent than those using SP (M = 16.2 vs. 13.3, p < .001), but lower depression scores (M = 22.2 vs. 26.8, p < .05). No significant differences were found in suicidal ideation (M = 20.1 vs. 23.1) or hopelessness (M = 10.1 vs. 11.9). At 12-month follow-up, depression scores decreased significantly for both groups, while hopelessness decreased only for the SP group. Limitations: The statistical power achieved was lower than intended. Conclusion: The higher levels of suicidal intent, but lower levels of depression, may indicate more impulsivity among people attempting suicide using VMs. Suicidal ideation was relatively stable.

尝试用暴力方法自杀和自中毒的患者自杀意向更高。

背景：假设使用暴力方法（VMs）尝试自杀的患者的自杀意图高于使用自体中毒（SP）的患者的自杀意图，这可能解释了在后续研究中观察到的更高的死亡率。但是，尚未对此进行前瞻性研究。目的：我们的目的是比较住院期间和术后1年内使用VM进行自杀尝试的患者与使用SP进行自杀尝试的患者在自杀意向，自杀观念，抑郁和绝望方面的自杀情况。方法：VM（n = 80）或SP（n = 81）自杀未遂后住院的患者入院时和随访12个月时，均完成了贝克意向，自杀意念，抑郁量表和绝望量表。结果：入院时，使用VM的人的自杀意图高于使用SP的人（M = 16.2对13.3，p <.001），但抑郁评分较低（M = 22）。2比26.8，p <.05）。自杀意念（M = 20.1 vs. 23.1）或绝望感（M = 10.1 vs. 11.9）没有发现显着差异。在12个月的随访中，两组抑郁指数均显着降低，而绝望率仅在SP组下降。局限性：获得的统计功效低于预期。结论：自杀意向水平较高，而抑郁水平较低，则可能表明使用VM自杀的人的冲动性更高。自杀念头相对稳定。获得的统计功效低于预期。结论：自杀意向水平较高，而抑郁水平较低，则可能表明使用VM自杀的人的冲动性更高。自杀念头相对稳定。获得的统计功效低于预期。结论：自杀意向水平较高，而抑郁水平较低，则可能表明使用VM自杀的人的冲动性更高。自杀念头相对稳定。
