The present study assessed the presence of testing effects arising from the repeated administration of both the Beck and Zung depression scales to a group of 60 inpatient alcoholics. Thirty-seven men and 23 women were randomly assigned to one of three groups and administered the depression scales on one, two or three occasions, in successive weeks of treatment. Although the between group comparisons of initial test administration did not indicate a true change in depression, a within group comparison of initial with subsequent test administrations indicated a clear improvement in depression scores on both scales. Apparently the result of the reactive effects of testing, the within group differences could easily mislead a researcher into believing depression was alleviated when in fact it was not. This sizeable testing effect has obvious implications for studies which repeatedly assess depression.
本研究评估了对一组60名住院酗酒者重复使用贝克抑郁量表和zung抑郁量表所产生的测试效应。37名男性和23名女性被随机分配到三个组中的一组，并在连续治疗周内接受一次、两次或三次抑郁量表测试。尽管组间初始测试的比较未显示抑郁有真正变化，但组内初始测试与后续测试的比较表明，两个量表的抑郁得分均有明显改善。显然，作为测试反应效应的结果，组内差异很容易误导研究人员认为抑郁得到缓解，而实际上并非如此。这种相当大的测试效应对于反复评估抑郁的研究具有明显的意义。
