Background The need for a culturally suitable scale for suicidality within the multilingual Nigerian society necessitated this research interest. Aim The study is a development and validation of the Redeemer's University Suicidality Scale (RUSS). Setting South western Nigeria. Methods This comprised of initial generation of items; face and content validity, item refinement and administration of RUSS to 150 university undergraduates, using exploratory factor analysis at the first, second and third stages. In the fourth stage, 184 undergraduates responded to the 20-item RUSS, Suicide Ideation Scale (SIS) and General Health Questionnaire (GHQ-12). Data gathered at this stage were analysed for congruent validity, reliability and norms. Results The principal component analysis extracted four components from items whose eigenvalues exceeded one. Twenty-one of the 25 items loaded best in the first, two in the second and one on the third component(s). Only items in the first component were retained. Item-total correlation further showed that the values of one item in the first component fell below the very good discrimination and was deleted from the scale. The RUSS has a Cronbach's alpha of 0.93. Congruence validity coefficient of r = 0.881 (p < 0.001) and r = 0.605 (p < 0.001) was observed between RUSS and SIS and between RUSS and GHQ-12, respectively. Conclusion The RUSS is gender-sensitive, has acceptable psychometric properties and is recommended as a diagnostic tool for assessing suicidal behaviour in adolescents and adults. Contribution This article contributes to the development of a culture sensitive measure for suicidality.

救世主大学自杀量表的开发和验证。

背景 在多语种的尼日利亚社会中，需要一个文化上适合的自杀量表，这使得这种研究兴趣成为必要。目的 本研究是救世主大学自杀量表 (RUSS) 的开发和验证。设置尼日利亚西南部。方法 这包括项目的初始生成；使用第一、第二和第三阶段的探索性因素分析，对 150 名大学本科生进行 RUSS 的表面和内容效度、项目细化和管理。在第四阶段，184 名本科生回答了 20 项 RUSS、自杀意念量表 (SIS) 和一般健康问卷 (GHQ-12)。分析在此阶段收集的数据的一致有效性、可靠性和规范。结果 主成分分析从特征值超过 1 的项目中提取了 4 个成分。25 个项目中的 21 个在第一个组件中加载得最好，两个在第二个组件中加载最好，一个在第三个组件中加载最佳。仅保留第一个组件中的项目。项目总相关性进一步表明，第一个组件中的一个项目的值低于非常好的区分度，并从量表中删除。RUSS 的 Cronbach α 系数为 0.93。在 RUSS 和 SIS 之间以及 RUSS 和 GHQ-12 之间分别观察到 r = 0.881 (p < 0.001) 和 r = 0.605 (p < 0.001) 的一致性有效性系数。结论 RUSS 对性别敏感，具有可接受的心理测量特性，推荐作为评估青少年和成人自杀行为的诊断工具。贡献 这篇文章有助于开发一种文化敏感的自杀措施。
