ghq: Psychiatric diagnosis based on GHQ

In SMIR: Companion to Statistical Modelling in R

Description

These data were published by Silvapulle, and come from a psychiatric study of the relation between psychiatric diagnosis (as case or non-case) and the value of the score on a 12-item General Health Questionnaire (GHQ), for 120 patients attending a general practitioner's surgery. Each patient was administered the GHQ, resulting in a score between 0 and 12, (however there were no cases or non-cases with GHQ scores of 11 or 12) and was subsequently given a full psychiatric examination by a psychiatrist who did not know the patient's GHQ score. The patient was classified by the psychiatrist as either a “case”, requiring psychiatric treatment, or a “non-case”.
