OBJECTIVE
Single-item questionnaire assessments may be summarily dismissed by some, but it is unclear if this is warranted. We suggest here that the answer to that question depends on their reliability and construct validity. Reliability of a single-item index cannot be assessed via indices like coefficient alpha, but it can be addressed otherwise; construct validity can be assessed as it would be with any other quantitative index.
METHODS
In 489 patients with mood and anxiety disorders, we examined the Beck Depression Inventory Item 9's (BDI-Item 9) test-retest coefficient, and its validity, in part via invariance analyses. More specifically regarding invariance analyses, we determined whether a covariance structure including a multi-item assessment of suicidal ideation was invariant with a similar structure using a single-item assessment of suicidal ideation instead.
RESULTS
Reasonably supportive evidence emerged for the reliability and construct validity of this specific one-item index.
CONCLUSIONS
The BDI-Item 9 can reliably assess suicidal ideation when data lack multi-item assessments.
目的
单项问卷评估可能会被一些人一概摒弃，但尚不清楚这样做是否合理。我们在此表明，这个问题的答案取决于它们的信度和结构效度。单项指标的信度无法通过诸如α系数等指标来评估，但可以通过其他方式解决；结构效度的评估方式与任何其他定量指标相同。
方法
在489例情绪和焦虑障碍患者中，我们检验了贝克抑郁量表第9项（BDI-Item 9）的重测系数及其效度，部分通过不变性分析进行。关于不变性分析更具体地说，我们确定了一个包含自杀意念多项目评估的协方差结构是否与使用自杀意念单项评估的类似结构具有不变性。
结果
出现了关于这一特定单项指标的信度和结构效度的合理支持性证据。
结论
当数据缺乏多项目评估时，BDI-Item 9能够可靠地评估自杀意念。
