The psychometric properties of the Beck Inventory (BI), a revised, copyrighted version of the Beck Depression Inventory (BDI), were investigated in 204 university students. Two-week test-retest reliability was .90, coefficient alpha was .87, concurrent validity using the BDI as the criterion was .94, and the correlation between level of depression as measured by the two instruments was .86. The mean score on the BI was significantly but only one-half point lower than that on the BDI. Individual items were all highly and significantly correlated, but a significantly lower BI mean score occurred on the Sadness, Suicidal Ideas and Insomnia items. Depression was not significantly related to demographic variables.
贝克量表（BI）是贝克抑郁量表（BDI）的修订版且受版权保护，对204名大学生的该量表心理测量特性进行了调查。两周重测信度为0.90，α系数为0.87，以BDI作为标准的同时效度为0.94，两种工具测量的抑郁水平之间的相关性为0.86。BI的平均得分显著低于BDI，但仅低0.5分。各个项目之间的相关性都很高且显著，但在悲伤、自杀观念和失眠项目上，BI的平均得分显著更低。抑郁与人口统计学变量无显著相关性。
