the rate of death by suicide has increased in Mexico, representing a significant public health problem. To prevent and treat this phenomenon, it is crucial to identify reliable suicide risk factors among Mexicans. The Interpersonal Theory of Suicide has demonstrated empirical support for the role of thwarted belongingness, perceived burdensomeness, and acquired capability in the development of suicidal desire and behaviors. The measure of the theory's constructs-the Interpersonal Needs Questionnaire (INQ) and the Acquired Capability for Suicide Scale (ACSS)-has also shown good psychometric qualities.
translate, culturally adapt and validate these instruments.
495 university students from Mexico City participated in two independent samples ( = 239; = 256). For the INQ, the available version in Spanish was used. For the ACSS, the most current version in English was used. Based on the results from the first sample, items were modified, eliminated, or added for the second sample.
the INQ demonstrated good fit (RMSEA = .054, TLI = .97, IFI = .97, NFI = .95) with an internal consistency of .77 and .87 for thwarted belongingness and perceived burdensomeness, respectively. The ACSS obtained similar results (RMSEA = .011, CFI = .99, TLI = .99, IFI = .99, NFI = .91); the internal consistency was .77.
the Spanish version of the instruments display good psychometric properties and can be used to measure the constructs of the interpersonal theory of suicide. However, further replication is needed to support generalizability in other Spanish-speaking populations.
墨西哥的自杀死亡率有所上升，这是一个重大的公共卫生问题。为了预防和治疗这一现象，识别墨西哥人中可靠的自杀风险因素至关重要。自杀人际理论已在经验上支持了归属感受挫、感知到自身成为他人负担以及习得自杀能力在自杀欲望和行为发展中的作用。该理论结构的测量工具——人际需求问卷（INQ）和自杀习得能力量表（ACSS）——也显示出良好的心理测量学特性。
翻译、进行文化调适并验证这些工具。
来自墨西哥城的495名大学生参与了两个独立样本（样本1 = 239；样本2 = 256）。对于INQ，使用了西班牙语的现有版本。对于ACSS，使用了最新的英语版本。根据第一个样本的结果，对第二个样本的项目进行了修改、删除或添加。
INQ显示出良好的拟合度（RMSEA = .054，TLI = .97，IFI = .97，NFI = .95），归属感受挫和感知到自身成为他人负担的内部一致性分别为.77和.87。ACSS获得了类似的结果（RMSEA = .011，CFI = .99，TLI = .99，IFI = .99，NFI = .91）；内部一致性为.77。
这些工具的西班牙语版本显示出良好的心理测量学特性，可用于测量自杀人际理论的结构。然而，需要进一步重复研究以支持在其他西班牙语人群中的普遍性。
