背景资料：16项抑郁症状快速量表（QIDS）是一种新的抑郁症状严重程度的测量方法，它是从30项抑郁症状量表（IDS）衍生而来的，可以在自我报告和自我报告中使用。（QIDS-SR 16）和临床医生评定（QIDS-C-16）格式。本报告评估和比较QIDS-SR 16与IDS-SR 30和24项汉密尔顿抑郁量表的心理测量学特性结果：QIDS-SR 16（Cronbach’s alpha=.86）、IDS-SR 30（Cronbach’s alpha=.92）和HAM-D-24（Cronbach’s alpha=.88）的内部一致性较高。QIDS-SR 16总分与IDS-SR 30（.96）和HAM-D-24（.86）总分高度相关。项目与总分的相关分析显示，几个相似的项目与QIDS-SR 16和IDS-SR 30总分均高度相关。大约1.3倍的QIDS-SR 16总评分是预测的HAM-D-17（17项版本的HAM-D）总score.Conclusions：的QIDS-SR 16是敏感的症状变化的IDS-SR 30和HAM-D-24，表明高并发效度为所有三个量表。QIDS-SR 16具有高度可接受的心理测量学特性，这支持了这种抑郁症状严重程度的简短评级在临床和研究环境中的有用性。
Background: The 16-item Quick Inventory of Depressive Symptomatology (QIDS), a new measure of depressive symptom severity, derived from the 30-item Inventory of Depressive Symptomatology (IDS), is available in both self-report (QIDS-SR16) and clinician-rated (QIDS-C-16) formats.Methods: This report evaluates and compares the psychometric properties of the QIDS-SR16 in relation to the IDS-SR30 and the 24-item Hamilton Rating Scale for Depression (HAM-D-24) in 596 adult outpatients treated for chronic nonpsychotic, major depressive disorder.Results: Internal consistency was high for the QIDS-SR16 (Cronbach's alpha=.86), the IDS-SR30 (Cronbach's alpha=.92), and the HAM-D-24 (Cronbach's alpha=.88). QIDS-SR16 total scores were highly correlated with IDS-SR30 (.96) and HAM-D-24 (.86) total scores. Item-total correlations revealed that several similar items were highly correlated with both QIDS-SR16 and IDS-SR30 total scores. Roughly 1.3 times the QIDS-SR16 total score is predictive of the HAM-D-17 (17-item version of the HAM-D) total score.Conclusions: The QIDS-SR16 was as sensitive to symptom change as the IDS-SR30 and HAM-D-24, indicating high concurrent validity for all three scales. The QIDS-SR16 has highly acceptable psychometric properties, which supports the usefulness of this brief rating of depressive symptom severity in both clinical and research settings.
