Improving the validity of the GHO30 by rescoring for chronicity: a failure to replicate.
To replicate the finding by Goodchild and Duncan-Jones (1985), that rescoring the GHQ30 in order to take account of chronicity would improve its validity, a random sample of 244 people completed the GHQ. Of these 102 also took part in a second interview in which they were administered the PSE. There was no evidence that the new scoring scheme improved correlations between the GHQ and other measures of morbidity nor did this improve its sensitivity or specificity when validated agaist the PSE.
