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.
