Abstract

Background: Identifying accurate methods of assessing suicidal ideation has important implications. The lack of a universal definition of suicidal ideation has complicated measurement efforts. This study details the development of a brief self-report measure of suicidal ideation which specifically focuses on thoughts of suicide.

Method: The Questionnaire for Suicidal Ideation (QSI) was developed by collating items from three existing measures of suicidal ideation. Items explicitly describing acts or behaviours were removed and Posner et al.'s (2007) definition of suicidal ideation was applied to the remaining items. The final questionnaire consisted of 6 items. Participants were adults (n = 192) and adolescents (n = 152) attending community mental health services in the Irish public health service.

Results: The QSI demonstrated excellent reliability in adult (α = .91) and adolescent ( = .90) samples. Exploratory factor analysis produced a one-factor solution explaining 70% and 66% of the variance in adult and adolescent samples respectively. Evidence of relation with other variables was demonstrated with strong correlations between the QSI and measures of depression, hopelessness and borderline symptoms (r = .48 - .68).

Conclusions: The results suggest that the QSI may be a reliable and valid method of assessing suicidal ideation in clinical populations.

自杀意念问卷（QSI）：在成人和青少年临床人群中测量自杀意念的简易工具的心理计量特性》（Psychometric Properties of a Brief Tool Measuring Suicidal Ideation in Adult and Adolescent Clinical Populations）。

背景：确定评估自杀意念的准确方法具有重要意义。由于缺乏对自杀意念的通用定义，使得测量工作变得复杂。本研究详细介绍了一种简短的自杀意念自我报告测量方法的开发过程，该方法特别关注自杀意念：自杀意念问卷（QSI）是通过整理现有的三种自杀意念测量方法中的项目而编制的。其中明确描述行为或举止的项目被删除，Posner 等人（2007 年）对自杀意念的定义适用于其余项目。最终问卷由 6 个项目组成。调查对象为在爱尔兰公共卫生服务机构接受社区心理健康服务的成年人（192 人）和青少年（152 人）：结果：QSI 在成人（= 0.91）和青少年（= 0.90）样本中显示出极佳的可靠性。探索性因子分析得出的单因子解分别解释了成人和青少年样本中 70% 和 66% 的变异。QSI与抑郁、绝望和边缘症状的测量结果（= .48 - .68）之间存在很强的相关性，证明了QSI与其他变量之间的关系：结果表明，QSI 可能是评估临床人群自杀意念的一种可靠而有效的方法。
