Suicide is a global public health problem. The goal of this study was to evaluate the psychometric properties of the measurement of suicide severity based on the Columbia suicide severity rating scale. We worked with a sample of 516 Argentinean adults, aged 18 to 75. The fit of a measurement model that differentiates between the various degrees of suicidal severity was verified. The specified model returns fit values above the suggested cut-off points, both for the occurrence and frequency indicators. The internal consistency indices from the composite reliability coefficient also show values above the cut-off points for both occurrence and frequency. Finally, evidence of construct validity was obtained from the relationship with external variables. The results are consistent with the theory, showing stronger effects of hopelessness on suicidal ideation compared to suicide attempts. Overall, evidence of construct validity for the measurement of suicidal severity is presented, a contribution that is essential in remedying the lack of studies on suicide in the region and promoting prevention strategies.
自杀是一个全球性的公共卫生问题。本研究的目的是评估基于哥伦比亚自杀严重程度评定量表对自杀严重程度测量的心理测量特性。我们对516名年龄在18至75岁之间的阿根廷成年人进行了抽样研究。验证了区分不同程度自杀严重程度的测量模型的拟合度。对于发生指标和频率指标，指定模型返回的拟合值均高于建议的临界点。综合信度系数的内部一致性指标在发生和频率方面也显示出高于临界点的值。最后，从与外部变量的关系中获得了结构效度的证据。结果与理论一致，表明绝望对自杀意念的影响比对自杀未遂的影响更强。总体而言，本研究提供了自杀严重程度测量的结构效度证据，这一贡献对于弥补该地区自杀研究的不足以及促进预防策略至关重要。
