To develop a short, 5-item measure of the core symptoms of depression based on the 16-item Quick Inventory of Depressive Symptomatology - Self-Report (QIDS-SR ) and to evaluate psychometric properties of this new measure (Very Quick Inventory of Depressive Symptomatology - Self-Report: VQIDS-SR ).
Using data from a convenience sample of the Combining Medications to Enhance Depression Outcomes (CO-MED) trial, we evaluated the psychometric properties of the VQIDS-SR , its sensitivity to change, and its comparability to the QIDS-SR and clinician-rated scales (QIDS-C and VQIDS-C ).
The VQIDS-SR has a single-factor structure with an acceptable internal consistency (Cronbach's alpha: 0.67-0.81). The VQIDS-SR was as sensitive to change as its parent scale, then QIDS-SR and, detected change at an earlier time frame. Additionally, the VQIDS-SR was comparable to the QIDS-SR , QIDS-C , and VQIDS-C .
The VQIDS-SR can effectively evaluate the core symptoms of depression during the course of treatment.
基于16项抑郁症状快速自评量表(QIDS-SR)开发一个简短的、包含5个条目的抑郁核心症状测量工具,并评估这个新测量工具(极短抑郁症状自评量表:VQIDS-SR)的心理测量学特性。
利用联合药物治疗改善抑郁结局(CO-MED)试验便利样本的数据,我们评估了VQIDS-SR的心理测量学特性、其对变化的敏感性以及它与QIDS-SR和临床医生评定量表(QIDS-C和VQIDS-C)的可比性。
VQIDS-SR具有单因素结构,内部一致性可接受(克朗巴哈系数:0.67 - 0.81)。VQIDS-SR对变化的敏感性与其母量表QIDS-SR相同,且能在更早的时间框架内检测到变化。此外,VQIDS-SR与QIDS-SR、QIDS-C和VQIDS-C具有可比性。
VQIDS-SR能够在治疗过程中有效评估抑郁的核心症状。
