The sensitivity of the GHQ and a revised scoring procedure (CGHQ) for chronic psychiatric complaints was investigated on 175 out-patients. The mean level of severity of symptoms of the groups with and without chronic complaints was not significantly different. However, patients with chronic complaints showed a significantly lower mean GHQ score than patients without chronic complaints. The mean CGHQ scores of the two groups did not differ, suggesting that the CGHQ is a better indicator of the severity of the chronic psychiatric state than the GHQ. The revised scoring procedure resulted in a decrease in the number of false negatives. The strongest reduction in false negatives, however, was induced by a combination of the original and the revised scoring procedures. This reduction was achieved at the expense of only a small increase in the number of false positives. Altogether, the revised scoring procedure proved to be only marginally better.
对175名门诊患者研究了一般健康问卷（GHQ）及一种修订评分程序（CGHQ）对慢性精神疾病主诉的敏感性。有慢性主诉组和无慢性主诉组的症状严重程度平均水平无显著差异。然而，有慢性主诉的患者GHQ平均得分显著低于无慢性主诉的患者。两组的CGHQ平均得分无差异，这表明CGHQ比GHQ更能较好地反映慢性精神状态的严重程度。修订后的评分程序减少了假阴性的数量。不过，假阴性减少最多的是原始评分程序与修订评分程序相结合的情况。这种减少是以假阳性数量仅少量增加为代价实现的。总体而言，修订后的评分程序仅被证明略好一点。
