贝克抑郁量表（BDI）是最广泛使用的抑郁量表之一。许多研究已经检验了BDI的可靠性和有效性。然而，我们没有发现已发表的研究考虑多次给药（即超过3次试验）时BDI的稳定性，如在临床试验研究和一些临床干预中常见的情况。本研究的目的是检验BDI在非临床样本中的多次重测信度。结果显示，BDI评分在8周内下降了40%，主要影响约占方差的10%。我们仅通过重复测量，而不是任何干预，就使自我报告的抑郁症状减少了40%。这种变化可能代表了该仪器的测量误差，而不是抑郁症的任何“真实”变化。本文讨论了本研究的局限性、研究意义及其在临床实践中的应用。
The Beck Depression inventory (BDI) is one of the most widely used measures of depression. Many studies have examined the reliability and validity of the BDI. However, we found no published studies that considered the stability of the BDI over multiple administrations (i.e., more than 3 trials), such as is common in clinical trials research and during some clinical interventions. The purpose of this study is to examine the multiple test-retest reliability of the BDI in a presumably nonclinical sample. Results show a 40% decline in BDI scores over 8 weeks, a main effect that accounts for approximately 10% of the variance. We achieved a 40% decrease in self-reported symptoms of depression due to repeated measurement alone, not due to any intervention. This change likely represents measurement error with this instrument rather than any "real" change in depression. The limitations of this study, its implications for research, and its applications to clinical practice are discussed.
