In trials performed by the General Practitioner Clinical Research Group two rating scales have been employed extensively to measure depression. One includes some 17 target symptoms whilst the second is a shorter scale of 11 items. Although extensively used, neither scale has been validated against other measures of depression. An attempt was made to validate the 11-item scale, completed by the physician, against the Zung self-rating depression scale and the Wakefield Inventory, both patient-completed scales. Using thirty depressed patients the correlation between the 11-item scale and the Zung was 0.59 and between the 11-item scale and the Wakefield it was 0.5. Surprisingly, although the two scales are patient-completed and purport to measure the same thing, the correlation between the Zung and the Wakefield scales was only 0.69. All the correlations were statistically significant at the 1% level.
在全科医生临床研究小组进行的试验中，两种评定量表被广泛用于测量抑郁症。一种包含约17种目标症状，而另一种是较短的11项量表。尽管被广泛使用，但这两种量表均未与其他抑郁症测量方法进行过验证。有人尝试将医生填写的11项量表与患者填写的Zung自评抑郁量表和韦克菲尔德量表进行验证。使用30名抑郁症患者，11项量表与Zung量表之间的相关性为0.59，11项量表与韦克菲尔德量表之间的相关性为0.5。令人惊讶的是，尽管这两种量表都是由患者填写且旨在测量相同的内容，但Zung量表与韦克菲尔德量表之间的相关性仅为0.69。所有相关性在1%水平上均具有统计学意义。
