This prospective study aimed to assess the suitability of the 21-item Beck Depression Inventory (BDI-21) as a screening method for current episodes of major depressive disorder in different phases of the disease. In a sample of treatment-seeking outpatients (n=125), a structured interview method (SCID) was used twice with a 2-year interval to screen whether the patient had a current episode of major depressive disorder. The validity of the BDI-21 was also analysed by means of receiver operating characteristic (ROC) curves. The results showed that with a cut-off point of 14/15 the BDI-21 can be used to indicate the presence of a major depressive episode regardless of the phase of the major depressive disorder. The sensitivity and specificity were quite satisfactory with this cut-off point. The areas under the ROC curves were large (0.81 at baseline and 0.93 at follow-up). The same BDI-21 cut-off point is suitable for screening major depression among outpatients in any phase of the disease.
这项前瞻性研究旨在评估21项贝克抑郁量表（BDI-21）作为在疾病不同阶段筛查当前重度抑郁症发作的一种方法的适用性。在一个寻求治疗的门诊患者样本（n = 125）中，采用结构化访谈方法（SCID），间隔2年进行两次，以筛查患者是否有当前的重度抑郁症发作。还通过受试者工作特征（ROC）曲线分析了BDI-21的有效性。结果表明，以14/15分为分界点，BDI-21可用于指示重度抑郁症发作的存在，而不论重度抑郁症处于何种阶段。该分界点的敏感性和特异性相当令人满意。ROC曲线下的面积较大（基线时为0.81，随访时为0.93）。相同的BDI-21分界点适用于筛查疾病任何阶段门诊患者中的重度抑郁症。
