Validity and uses of a screening questionnaire (GHQ) in the community.
The 30-item General Health Questionnaire (GHQ) has been validated against the criterion of a standardized psychiatric interview in the community. Used for screening, the GHQ misclassified 25 per cent of 105 respondents, being worse for men. Specificity and sensitivity were above .70. The alternative use of the GHQ as an estimator and as an indicator of morbidity in epidemiological surveys is described and discussed.
