Abstract

Objective: To test the factor structure, reliability, and validity of the Brazilian version of the Abbreviated Suicidal Narrative Inventory (SNI-38).

Methods: We used an anonymous online questionnaire of the SNI-38 and self-report measures administered between November 2020 and October 2021 in the Brazilian community. Participants were recruited through social media advertisements. Confirmatory factor analysis (CFA) was performed to test the factor structure of the SNI-38. In addition, we assessed internal consistency and convergent validity against stressful life events, suicide crisis syndrome, suicidal ideation, and suicide attempts.

Results: A total of 2,660 participants were included. The eight-factor model of the SNI-38 had a good model fit (?2[637] = 7,473.98, p < 0.001, comparative fit index [CFI] = 0.99, Tucker-Lewis index [TLI] = 0.99, root mean squared error of approximation [RMSEA] = 0.07, standardized root mean residual [SRMR] = 0.06). Notably, all items were significantly and positively loaded onto their respective factors (factor loadings = 0.45). The reliability of all subscales except for goal disengagement ranged from good to high. Furthermore, all subscales except goal disengagement showed positive correlations with variables such as suicide crisis syndrome, stressful life events, lifetime/past month suicidal ideation, and lifetime suicide attempts.

Conclusion: These findings provide preliminary support for the validity of the Brazilian version of the SNI-38 as an appropriate, valid instrument for measuring suicidal narratives in Brazilian individuals.

简略自杀叙事量表：巴西样本的因子结构、内部一致性和有效性。

目的：研究巴西版简易自杀叙事量表（SNI-38）的因子结构、可靠性和有效性：我们在 2020 年 11 月至 2021 年 10 月期间在巴西社区使用了 SNI-38 匿名在线问卷和自我报告测量方法。参与者是通过社交媒体广告招募的。我们进行了确认性因子分析，以检验 SNI-38 的因子结构。此外，我们还检验了内部一致性，以及与生活压力事件、自杀危机综合征、自杀意念和自杀未遂的收敛效度。SNI-38八因子模型具有良好的模型拟合度（χ2[637] = 7,473.98, p < .001，CFI = .99，TLI = .99，RMSEA = .07，SRMR = .06）；所有项目都在各自的因子上有显著的正负荷（因子负荷≥ .45）。除目标脱离外，所有子量表的信度均为良好或较高。此外，除目标脱离外，所有分量表均与自杀危机综合征、生活压力事件、生前/上月自杀意念和生前自杀未遂呈正相关：这些研究结果为巴西版 SNI-38 的有效性提供了初步支持，它是测量巴西样本自杀叙事的适当而有效的工具。
